    15 20 25 30 leaks at the upper edge of the door, especially great difficulties in maintaining the desired pressure in the furnace as well as good combustion economy and energy efficiency.
    These problems therefore exist when the door is closed, but also when the door is partially open.
    Namely, a door which is opened by being raised upwards means that the opening into the oven extends from the lower edge of the door opening and upwards to the lower edge of the door in the partially opened condition of the door. As long as a good seal can be guaranteed at the top of the door, even if the door is partially open, the gas exchange between the oven and the surroundings, which is less strong further down in the oven due to the lower pressure there, will be limited.
    The present invention solves the above problems.
    Thus, the present invention relates to a sealing pipe for a door to an industrial furnace adapted to be mounted vertically and filled with a liquid cooling medium, the pipe comprising an upper end arranged to face upwards when the pipe is mounted, and an opposite lower end , wherein the tube further comprises a first longitudinal opening arranged to receive a side edge of the door, and thereby slidably along the longitudinal direction of the tube be able to accommodate the side edge, and where the tube is arranged that, when the tube is so filled with the coolant that the coolant substantially fills the space defined in the cross section of the pipe perpendicular to its longitudinal direction by the combination of the inner surfaces of the pipe and the outer surfaces of the door around the side edge, sealingly connecting to the side edge of the door, and characterized in that the pipe also comprises a second longitudinal opening; to run from the upper end of the pipe and a piece towards the lower end, by that Application textdocx 2010-01-2 The first longitudinal opening runs further towards the lower end than the second longitudinal opening, in that the upper end of the tube is open between the mouth of the two longitudinal openings in the upper end of the tube, and in that the second longitudinal opening is arranged to be able to receive and slidably in the longitudinal direction of the pipe housing an elongate vertical sealing part of the door which is inserted into the second longitudinal opening along the longitudinal direction of the pipe from the upper end of the pipe.
    In the following, the invention will be explained in more detail, partly in connection with exemplary embodiments of the invention, and with reference to the accompanying drawings, in which: Figure 1 is a simplified perspective view of a part of a first preferred hatch sealing device according to the present invention. comprising a sealing pipe according to the invention; Figure 2 is a simplified perspective view of the hatch sealing device according to Figure 1 seen from the right side in 3-5 Figure 1; The figures are simplified perspective views from above of the door sealing device according to figure 1, where the upper part of the door sealing device is removed at. the horizontal section A, B and C, respectively, in Figure 1; Figure 6 is a simplified perspective view of a second preferred hatch sealing device according to the present invention, comprising a sealing tube according to the invention, in the form of a principle sketch; Figure 7 is a simplified perspective view from the right of the hatch sealing device according to Figure 6, where the right part of the hatch sealing device is removed at the vertical section D; Figures 8-10 are simplified perspective views from above of the hatch sealing device according to Figure 6, where the upper part of the hatch sealing device is removed far beyond the horizontal section E, F and G, respectively, in Figure 6; and Application text document 2010-01-26 100010EN 10 15 20 25 30 Figures 11-12 are two perspective views, from right and left, respectively, over the door sealing device according to figure 1 where the door is partially opened.
    Figures 1-5 and 6-10, respectively, illustrate corresponding views of the two preferred embodiments, and the same reference numerals are used for corresponding parts. The hatch sealing device illustrated in Figures 1-5 shows, for reasons of clarity, only one half (the left half in Figure 1) of the sealing device, where it is understood that the other half can advantageously be substantially mirror-symmetrical in relation to the half shown.
    The hatch sealing device illustrated in Figures 6-10 is a very simplified principle sketch, the purpose of which is to illustrate the principle of the present invention. The hatch sealing device illustrated in Figures 1-5 is more detailed. than the principle sketch, but is also simplified, and the dimensions in both figures are partly exaggerated, to increase the clarity of the figures.
    In the following, the door sealing device is described. only with reference to one half thereof, and it will be appreciated that corresponding properties may be ascribed to the other half as well.
    Figures 11-12 show the same partially removed door sealing device as in Figures 6-10, but with the door raised from a completely closed position to a partially open position.
    An industrial furnace 100 is provided in one of its side walls with a through opening 110 for introducing material into or out of the furnace 100. A vertically arranged and openable door 200 is arranged to be able to tightly cover the through application text 2010-01-26 100010EN 10 15 20 25 30 the opening 110. The door 200 is opened by moving it upwards, and closed again by lowering it back to the original position. The door 200 is shown in Figures 1-10 in the closed position and in Figures 11-12 in the partially opened position.
    The connection of the door 200 to the oven 100 is preferably arranged to be sealed around its entire periphery, i.e. the side edge 201, edge 203 of the door 200, along its upper edge 202 and its lower one by means of a door sealing device 300 according to the present invention.
    The door sealing device 300 comprises a vertically arranged sealing tube 310, in which the vertical side edge 201 of the door 200 is arranged to be received and along which the side edge 201 is arranged to run slidably. This is most clearly shown in Figures 4, in which the sealing tube 310 is formed as a circular cylinder, and in 9, in which the tube 310 is in the form of a rectangular cavity in the wall of the furnace 100. The sealing tube 310 preferably extends at least along the length of substantially the entire side edge 201 when the door 200 is in the closed position, and substantially along the entire side edge 111 of the entire opening 110.
    The sealing tube 310 is provided with a first longitudinal opening 314, 318, preferably and as illustrated in Figures 1-5 in the form of a groove extending from an upper end 311 of the sealing tube 310, arranged to face upwards, and further downwards when the sealing tube 310 is mounted for operation as part of the sealing device 300.
    The side edge 201 of the door 200 is then inserted into the sealing pipe 310 through the groove 314, 318, and is arranged therein to be completely enclosed by the pipe 310 when the door 200 is in the closed position. When the door 200 is opened or closed, its side edge 201 runs inside the tube 310 in the longitudinal vertical direction of the tube 310.
    Application text doc. 2010-01-26 100010EN 10 15 20 25 30 Here, the term “vertical”, as used to describe the sealing tube 310, the side edge 111 of the door 200 and so on, refers to a spatial orientation which is substantially vertical. In other words, a vertically arranged part does not have to be absolutely vertical, but can have a certain horizontal directional component, as long as. the orientation is sufficiently vertical to allow an elongate water column to be present for sealing purposes in or adjacent to the verse below. In other words, the opening 110 of the furnace 100 may be slightly sloping, as long as it has a vertical component which is larger, preferably substantially larger, than its horizontal component.
    A liquid refrigerant circulation device (not shown) is arranged to continuously allow refrigerant 370, shown in Figures 6-10 but not Figures 1-5 and 11-12, to flow through the tube 310, by supplying refrigerant 370 at a supply point, preferably to the tube 310 or to an upper trough 350 (see below), and preferably level with or above the upper end 311 of the tube 310 in the direction of gravityl Det. It is further preferred that a lower trough 360, located directly below the lower end 312 of the tube 310, opposite the upper end 311, is arranged to collect the coolant 370.
    The refrigerant is arranged to flow through the lower end 312, and the circulation device is further preferably arranged to return the refrigerant 370 to the supply point by means of a pump which is conventional per se (not shown). so designed 314, 318 is According to a preferred embodiment, the tube 310 is that it springs back towards a position where the groove is closed. The resilient action of the tube 310 can be achieved in that the tube 310 itself is formed in a resilient material, or comprises spring means (not shown) which cause the tube 310 to spring back towards a position in which the grooves 314, 318 are closed.
    Alternatively, and as shown in Figures 1-5, however, the tube 310 includes an outer tube 317, made of a rigid material, preferably metal, and an inner tube 313, made of a flexible material. The outer tube 317 and the inner tube 313 are preferably concentric. The inner tube 313 further comprises a longitudinal groove 314, which corresponds to the longitudinal groove 318 along the outer tube 317 and which is arranged to receive and house the side edge 201 of the door 200 together with the groove 318.
    Such a construction results in a robust and heat-resistant yet simple and thus cost-effective solution.
    The structure shown in Figures 6-10 includes only one tube 310, with no inner tubes.
    The inner tube 313 is preferably made of a resilient material, for example in the form of a thick rubber tube with the notch 314 as a longitudinal and continuous section.
    According to a preferred embodiment, however, the outer diameter of the flexible tube 313, when the tube 313 is at rest, is larger than the inner diameter of the outer tube 317, and the edges 315 of the flexible tube 313 at the notch 314 are curved or folded toward the center of the outer tube 317. when mounted in the outer tube 317 and when the side edge 301 is inserted through the cup 318, folded edges 315 provide above the tubes 314 which said spring action. This results in a very good seal during operation, as described below.
    Application text document 2010-01-26 100010EN 10 15 20 25 30 According to a particularly simple and therefore preferred embodiment, the flexible tube 313 is designed as a mat of flexible inner material, advantageously wider than the circumference of the outer tube 317, which mat in the rest state is substantially flat but which is rolled into a tube shape when mounted in the outer tube 317.
    It is also possible to supplement a resilient outer tube with an inner, flexible tube 313 as above.
    According to the invention, the circulation device is arranged to provide continuous flow of the coolant 370 through the outer tube 317, so that the coolant 370 substantially fills the space defined in the cross section of the tube 310 by the combination of the inner surfaces of the tube 310 and the outer surfaces of the door 200 around the side edge 201. If several interlocking tubes are used as above, for example an inner flexible tube 313 together with an outer rigid tube 317, the coolant 370 is arranged to flow through the inner or innermost tube 313 and substantially fill the entire space between the inner surfaces of this tube and the outer surfaces of the side edge 111.
    The refrigerant 370 according to a preferred embodiment is water, but may be any suitable liquid refrigerant, such as water with a suitable conventional friction reducing and / or abrasion reducing additive conventionally, or a suitable liquid low friction cooling medium.
    The circulation device is arranged to continuously discharge the coolant 370 from the tube 310 by means of gravity, for example via leakage from the tube 310 through the groove 314, 318 or through leaks or other openings in the tube 310.
    Because the coolant 370 continuously flows through the tube 310, it cools efficiently during operation, and it is therefore possible to achieve a satisfactory service life of the tube 310.
    Furthermore, the spring action of the tube 310 ensures back against the lock 314, the position where the groove 314, 318 is closed that the groove 314, 318 tightly closes around the outer sides 201 of the side edge 201. That the groove 318 "closes tightly" is to be interpreted as meaning that no gas can pass through the groove 314, 318 when the pipe 310 is filled with coolant 370 at least up to a certain level 371 in the pipe 310. The level 371 is regulated, by means of the circulation device, so that it is high enough to achieve a satisfactory seal according to the other hand, can leak the invention. The refrigerant 370, through the groove 314, 318 to some extent as long as the level 371 can be maintained despite the leakage. According to a preferred embodiment, the lower end 312 of the tube 310 is provided with a flow valve (not shown), which is continuously controlled by the circulation device to regulate the liquid level 371.
    The pipe 310 is tightly attached to the outer wall of the industrial furnace 100 by means of sealing fasteners 320. Furthermore, an overpressure occurs inside the pipe 310 due to the liquid column of coolant inside the pipe 310, which causes the volume between the inner surfaces of the pipe 310 in combination with the outer edge 201 of the door 200. surfaces are always filled with coolant during operation. Thereby an effective seal is achieved between the side edge 201 of the door 200 and the side edge 111 of the opening 110 on the oven 100.
    Since the tube 310 is arranged to spring back towards a position where the groove 314, 318 is closed, the liquid column in the tube 310 will also be maintained along the parts of the tube. Application text doc. 2010-01-26 100010EN 10 15 20 25 30 10 310 under the door 200 side edge 201 along which the side edge 201 of the door 200 does not extend when the door 200 is fully or partially opened.
    According to the present invention, in addition to the first longitudinal opening 314, 318, the tube 310 also comprises. a second longitudinal opening 316, 319 running from the upper end 311 and a piece downwards towards the lower end 312. Both the longitudinal openings 314, 318; 316, 319 extend all the way up to, and open into, the upper end 311. The first longitudinal opening 314, 318 is arranged to run further down towards the lower end 312 than the second longitudinal opening 316, 319, to, preferably all the way from the upper end 311 forward and opening into, the lower end 312. In addition, it is preferred that the vertical distance between the end of the first longitudinal opening 314, 318 downwards and the corresponding downward end of the second longitudinal opening 316, 319 be greater than that of the opening. 110 height. In addition, the upper end 311 of the tube 310 is at least partially open, especially adjacent the mouth of the upper end 311 of the two longitudinal openings 314, 318; 316, 319, and in particular so that the two orifices are connected to each other by means of an opening in the upper end 311 of the tube 310 so that a sealing part in the form of a metal plate can be inserted into the tube 310 and the two longitudinal openings 314, 318; 316, 319 from above when mounted for operation via said opening in the upper end 311.
    As illustrated in the figures, the second longitudinal opening 316, 319, as well as the first longitudinal opening 314, 318 are arranged as a radially through opening through the tube 310, tube 313, i.e. through all superimposed 317.
    According to the invention, the second elongate opening 316, 319 is further arranged to be able to receive and slidably in the longitudinal direction of the tube 310 accommodate an elongate vertical sealing part 204 of the door 200, which sealing part 204 can be passed and is accommodated in the second longitudinal opening 316, 319 along the longitudinal direction of the tube 310 from the upper end 311 when mounting the door 200. Such an insertion is made possible by the second opening 316, 319 opening into the upper end 311, which is at least partially open, as described above. 319 can i 318.
    The second longitudinal opening 316, cross-sections similar to the first longitudinal opening 314, However, the tube 310 is preferably not arranged to spring back towards a position in which the second longitudinal opening 316, 319 is closed. According to a preferred embodiment, the second opening 316, 319 is formed as a longitudinal section in the tube 310 which is so wide that it can marginally receive the vertical sealing part 204. In other words, the lower part of the sealing part 204 is arranged to be surrounded by coolant 370 as it passes through the second longitudinal opening 316, 319.
    As best seen in Figures 2, 3, 7 and 8, the second opening 316, 319 is adapted to be connected to an upper trough 350 for coolant 370, so that a liquid connection 351 is established between the upper trough 350 and the tube 310 via the second 319. the opening 316, When the level 371 of coolant 370 in the tube 310 and / or the upper trough 350 is sufficiently high, the coolant can thus be caused to form a continuous body which is common to the tube 310 and the upper trough 350. Such a continuous body of refrigerant 370 can be provided, for example, by continuously supplying the refrigerant 370 to the upper trough 350 and then allowing it to flow from the upper trough 350, via the liquid connection 351 and down into the tube 310. , so that the level of coolant 370 in both the upper trough 350, the liquid connection 351 and the tube 310 can be kept constant. Alternatively, the upper trough 350, the liquid connection 351 and the tube 310 may share a common liquid surface of refrigerant, which has the same level everywhere but per se may be continuous or fragmented, the trough 350, the connection 351 and the tube 310 forms communicating vessels.
    By means of such a sealing pipe 310 a sealing connection between on the one hand a substantially horizontal, upper seal between the upper edge 202 of the door 200 and the furnace 100 and on the other hand a substantially vertical seal can be provided between the side edge 201 of the door 200 and the furnace 100, since a side edge 335 of a part of the sealing means 20 of the door 200 for its upper edge 202 can be arranged so as to run into the tube 310 through the second longitudinal opening 316, 319 and into the environment inside the tube 310 sealing due to the coolant 370 connect to the side edge 201 of the door 200, the parts of the door 200 sealing the upper edge 202 and side edge 201 of the door 200 to the oven 111 and the connection between said edges 201, 202 running entirely through a continuous body of coolant 370.
    This is described in more detail in the following. A door sealing device 300 according to the present invention for the connection of the door 200 to the opening 110 thus comprises a sealing pipe 310 as above. It will be appreciated that the sealing device 300 typically includes a sealing tube 310 at both sides of the door 200, as illustrated in Figures 6-10. When the pipe 310 is sufficiently filled with coolant, the door 200 is sealed against the oven 100 by having its side edge 201 running inside and along the pipe 310 as described in OVEBII.
    According to the invention, the sealing device 300 further comprises the upper trough 350, which is arranged above the upper edge 112 of the opening 110 and is additionally sealingly connected to the furnace 100, and a U-shaped projection 330 sealingly connected to the door 200, comprising a first upwardly from the door 200 extending part 331 and a second again downwardly extending part 333. When the door 200 is at the end, i.e. completely immersed, position, and the upper trough 350 is sufficiently filled with coolant 370, a lower edge 334 of the second part 333 is arranged to run below the level 371 for, and completely enclosed by, cooling medium 370 in the upper trough 350. Thus, a sealing connection between the door 200 and the oven 100 along the entire upper edge 112 of the opening 110 can be achieved. also the liquid connection The sealing device 300 comprises 351, between the upper trough 350 and the pipe 310 via the second longitudinal opening 316, 319 of the pipe 310, which connection 351 is arranged to enable the coolant 370 to be common to the upper trough 350 and the pipe 310 when both are sufficient. filled with refrigerant, as described above.
    As best seen in Figures 3 and 8, respectively, the sealing device 300 also includes a connection 336 between the second portion 333 of the U-shaped projection 330 and the side edge 201 of the door 200, which by running inside and along the tube 310 forms the vertical of the door 200. sealing part. The connection 336 is arranged to be located partly below the liquid level 371 of the coolant 370, when the upper trough 350 and the tube 310 are sufficiently filled with coolant and the door 200 is also closed. The part of the connection 336 which in this position is arranged above the liquid level 371 in the tube 310 is arranged to sealingly connect the second part 333 of the projection 330 to the side edge 201 of the door 200. Since it part of the connection 336 which is arranged below the liquid level 371 will be sealing due to the coolant 370, thus the whole connection 336 becomes sealing.
    According to the preferred embodiment illustrated in Figure 3, the first 331 and second 333 parts of the U-shaped projection 330, the upper part of the side edge 201 of the door 200 and the connection 336 form a single, continuous wall running on the upper edge 202, 318 and second 316, running along the door transverse through the tube 310 via the first 314, 319 longitudinal openings and back again parallel along the upper edge 202 of the door 200. In this case, the first part of the U-shaped projection 330 331 at its side edge 332 in fact the upper part of the side edge 201 of the door 200.
    According to the preferred embodiment illustrated in Fig. 8, the first part 331 of the U-shaped projection 330 is in fact constituted by the upper part of the door 200, which thus forms part of a continuous wall corresponding to the embodiment illustrated in Fig. 3, and which also includes the second portion 333 of the U-shaped projection 330 and the connection 336.
    Thus, this transverse 310, 310, continuous wall runs through. the tube in a plane perpendicular to a diameter of the tube via the two longitudinal openings 314, 318; 316, 319, which openings are thus arranged at two different angular positions in the tube 310. with a roof part 340. The continuous wall is provided see figures 1, 2, 6, 7. The roof part 340 is sealingly connected to both the U-shaped the first 331 and second 333 parts of the projection 330 and to the connection 336, and the application text doc. 2010-01-26 100010EN 10 15 20 25 30 l5 is arranged to seal on one side the seal between the side edge 201 of the door 200 and the pipe 310 and. on the other hand, the seal between the second part 333 of the U-shaped projection 330 and the upper trough 350 when the door 200 is closed and the upper trough 350 and the tube 30 are sufficiently filled with cooling medium 370.
    The latter seal is provided by the above-described continuous wall and roof portion 340 together forming a dense, hood-like structure. Since the second part 333 of the U-shaped projection 330 runs along the upper trough 350 below the level 371 of coolant 370 and further, all the time below said level 371, into the tube 3010, and there connects, via the connection 336, to the side edge of the door 200 20l, which in turn continues downward along the pipe 310, all the way enclosed by coolant 370, no gas will be able to leak into or out of the hood structure, neither via the horizontal seal, the vertical seal or the connection between these two respective seals .
    As most clearly illustrated in Figures 1 and 6, according to a preferred embodiment, the first 331 and second 333, respectively, of the first 331 and second 333, respectively, of the U-shaped projection 330 are connected to each other through the connection 336 both in the tube 300 and also inside part of the tube 301 extension outside the tube 310 above its upper end 311. In other words, the roof portion 340 is arranged outside and above the pipe 310.
    In the preferred case where the door sealing device 300 comprises two sealing pipes, each of which is arranged to sealingly connect a respective side edge of the door 200 to the oven 100, the upper trough 350, the roof part 340 and the U-shaped projection 330 are preferably common to both pipes. Thus, the above-described continuous wall seen from above in the figures will form a closed curve, which is tightly closed by means of the roof part 340. This is most clearly shown in figure 6. Thus formed a tight-fitting hood which effectively seals all the edges of the door 200 against the oven 100, except possibly between the lower edge 203 of the door 200 and the lower edge 113 of the opening 110.
    This seal is effective as described above as long as the liquid level 371 of coolant 370 is sufficiently high and as long as the door 200 is in the closed position. According to a further preferred embodiment, however, the upper trough 350 is deep enough, and both the second part 333 of the U-shaped projection 330 and the sealing part of the connection 336 between the second part 333 of the U-shaped projection 330 and the side edge 201 of the door 200 are high enough that the lower edge 334 of the second part 333 of the U-shaped projection 330 should be completely immersed in coolant 370 in the trough 350, and that the part of the connection 336 which is arranged above the liquid level 371 of the coolant 370 in the tube 310 connect the second portion 333 of the U-shaped projection 330 to the side edge 201, for all positions of the door 200 from fully closed to sufficiently open for full access to the opening 110 in the oven 100, all provided that the tube 310 and the upper trough 350 are connected sufficiently filled with refrigerant 370.
    The effect of such an arrangement is most easily seen from Figures 11 and 12, where the door 200 is shown in a partially opened position.
    From Figure 12 it can be seen that the part of the connection 336 which is arranged above the liquid level 371 sealingly connects the second part 333 of the U-shaped projection 330 and the side edge 201 of the door 200 is in the form of a solid, 200-sloping, tight wall. When the door, this tight wall is thus moved downwards along the pipe Application text 2010-01-26 100010EN 10 15 20 25 30 17 310 and the two longitudinal openings 314, 318; 316, 319, as described above. From the cross-section shown in Figure 12, it can be seen that the second part 333 of the U-shaped projection 330 is still arranged partly in the upper trough 350, despite the fact that the door 200 has been opened in relation to its closed position. In order to adapt the sealing device 300 to close tightly for a certain largest hatch opening, a sufficient depth for the upper trough 350 and a sufficient height for the connection 336 is selected.
    In this way, a complete seal can be achieved along all the edges of the door 200, possibly except at the lower edge 203 of the door 200, even if the door 200 is fully or partially opened. Thus, problems with leakage at door opening can be reduced, since the gas pressure in the furnace 100 is higher further up in the furnace 100 and therefore constitutes a minor problem below the lower edge 203 of the door 200.
    According to a preferred embodiment, moreover, the lower edge 203 of the door 200 is arranged that, when the door 200 closes, it is lowered into the lower trough 360 to a position below the liquid level therein, so that a sealing connection between the lower edge 302 of the door 200 and the oven 100 is achieved when the door 200 is in the closed position and the lower trough 360 is sufficiently filled with coolant 370.
    This thus provides a seal also along the lower edge 203 of the door 2003. The level in the lower trough 360 is regulated in a conventional manner by means of a circulation device for an outflow in the vicinity of the lower trough (for example by means of a flow valve (not shown). the bottom of the trough 360.
    According to a particularly preferred embodiment, which is most clearly illustrated in Figures 5 and 10, respectively, in the position when the lower trough 360 is sufficiently filled with coolant 370, the lower end of the tube 310 is 310. 312 arranged in the lower trough 360 so far down that the end 312 is completely immersed in the coolant. As the refrigerant 370 continuously flows down through the tube 310, this results in the tube and out into the lower trough 360, 310 sealingly connecting to the lower trough 360. Furthermore, the lower edge 203 of the door 200 connects to a lower end of the side edge of the door 200. 201, so that a tight connection is achieved between, on the one hand, the seal between the side edge 201 of the door 200 and the pipe 310 and, on the other hand, the seal between the lower edge 203 of the door 200 and the lower trough 360. In this way, when the door 200 is completely closed, , a complete seal of all the edges of the door 200 in relation to the oven 100.
    In other words, in the manner described above, the sealing device 300 provides a complete seal of the door 200, so that atmospheric air can not leak into the industrial furnace 1 and so that the gases of the furnace atmosphere can not leak out of the furnace 100.
    The above invention has been explained above. reference to exemplary embodiments. However, it will be appreciated that the invention is not limited to the embodiments described, but may be varied within the appended claims.
    In particular, geometric configurations other than those specifically shown in the figures may be useful in achieving the advantages described above, as long as such configurations include the necessary parts and the connections between them described above to achieve the present sealing objects.
