    A forehearth for the conveyance of molten glass has a cooling zone (10, 12) with a roof (17) having two spaced downward projections (28, 30) which define a central channel (36) and two side channels (38, 40). The roof (17) has an area of reduced thickness (44) over the central channel and an enclosed upper cooling channel (54) extends longitudinally of the forehearth over the area of reduced thickness so that cooling air can flow along the cooling channel longitudinally of the forehearth out of contact with the glass.

    专利说明:

    The invention relates to glass industry and can be used when feeding glass mass from a glass furnace bath to a feeder.
    The purpose of the invention is to increase the reliability of the device.
    FIG. 1 shows the feed channel, the horizontal section; in fig. 2 - the same, vertical section; in fig. 3 - the same cross section; in fig. 4 — leveling zone of the feed channel, partial cross section; in fig. 5 - overlapping block placed above the holes in the arch block, end view.
    The feeding channel of the glass melt is made of refractory material and installed in a metal supporting structure 1 where insulating bricks 2 are located. In order to enable the installation of the feeding channel at a certain level, a layer 3 of powdered alumina is poured between the groove.
    A channel may include a plurality of substantially identical cooling zones 4 and 5. An anterior air conditioning zone 6 adjoins the front end of zone 5.
    The code of each cooling zone 4 and 5 contains blocks 7 in which burners 8 are installed for heating the glass. Burners 8 are spaced apart along cooling zones 4 and 5 on both sides. The arch contains many blocks 9, laid close to each other along the length (

    O4
    3150
    zones 5 and 6 of cooling from above on blocks 7 and fixed in the supporting structure. Each block 9 consists of two parts 10 and 11. The blocks of arch 9 have two protrusions 12 and 13 that are at some distance from each other, which extend down to the glass below the level of the central line of the burners. Each protrusion 12 and 13 has a curved inclined surface 14 facing the blocks 7, and a flat surface 15 facing the flat surface 15 of the other protrusion. Due to this design, three transversely spaced longitudinally extending channels from the lower side of the roof are formed, namely the central channel 16 located above the central part of the molten glass flow, and the side channels 17 and 18. The blocks of the roof 9 have a Y-shaped notch 19 formed by cutting off both corners of the inner end of parts 10 and 11 of block 9. When stacking a number of blocks 9, the conjugate V-shaped notches 19 form an almost square hole 20 that passes through the blocks 9.
    Each of the longitudinally spaced holes 20, passing through the roofing blocks and communicating with the central channel 16, is covered with a blocking block 21 of refractory material having good thermal conductivity. On top of the blocks 9 are insulated blocks 22 which are used to form a closed longitudinal channel 23 in each cooling zone A and 5, having an inlet 24 for cooling air inlet and an outlet 25 for outgoing cooling air. The upper surface of block 21 may be ribbed. Ribs 26 extend longitudinally to increase heat transfer.
    Each of the cooling zones 4 and 5 has two exhaust holes 27, one of which communicates with one side channel 17, and the other communicates with the other side channel 18. An adjustable damper 28 is provided for each of the exhaust holes. Projections 12 and 13 of blocks 9 extend below the level of the burner axes. Thus, the external surfaces
    four
    The 14 protrusions 12 and 13 will serve to radiate heat back to the glass melt, thereby helping to reduce the temperature gradient.
    Cooling of the sub-channel can be ensured by forming a divided cooling channel 29 in the insulating units. It also provides a transverse channel 30 having a partition 31 for providing two passage ways for admitting cooling air into the cooling channel 29.
    The conditioning zone 6 does not have any means for cooling molten glass, but it does have means for heating. The conditioning zone 6 includes a U-shaped channel 32 of refractory material, installed in the supporting structure 1 with the placement of the insulating blocks 33. On both sides of the gutter, blocks 34 are placed close to each other in which the burners are installed. On blocks 34 impose close to each other blocks 35 of the arch. Each block 35 consists of a single element, the central part 36 of which protrudes down below the level of the central line of the burners. The protrusion 36 usually has a triangular cross section and thus includes an inclined surface 37. Heat, reflected from it, goes down to the outer parts of the glass in the channel 32. The protrusion 36 forms two channels 37 and 38 under the blocks 35.
    Exhaust channels 39 and 40 are provided in the roof and insulation block to ensure the discharge of combustion products. The channels 39 and 40 have the usual independently adjustable shutters 41, which, when adjusted, provide the desired degree of traction. In the feed channel, the central part of the glass flow is cooled by cooling air passing in the longitudinal direction that is not in contact with the glass. Cooling air In each zone, it is controlled independently. There is a heating means for the outer parts of the glass flow. The heating means on each side in each zone is independently controlled. The heating means may include gas burners or may include electrodes immersed in the flow of glass and located through the Defined
    intervals along the channel, so that the flow of current leads to preferential heating of the glass along the edges. The bottom of the central part of the glass flow is also cooled, which is independently controlled, which increases the reliability of the device.
