    A process and apparatus based on a high temperature resistant conveyor belt constructed so as to be able to undergo expansion in any direction, and consisting of two separated but joined elements (1, 2) carrying out the separate functions of load bearing (1) and of driving (2). The belt is enclosed in a tight sealed steel box (15) applied to the boiler bottom, so that the belt continuously receives and discharges the ash.

    专利说明:

    The invention relates to the continuous removal of ash from under the furnaces of steam boilers, in particular, to devices for the dry removal of ash from the bottom.
    The purpose of the invention is to simplify the process of removing ash and increasing its efficiency.
    Figure 1 shows the device, side view; figure 2 - sections aa and bb in figure 1; Fig. 3 shows a conveyor belt passing along the surface of the driving drum; figure 4 is the same, bottom view; FIG. 5 a section bb of FIG. four; in fig. 6 - support detail, section.
    The device for the continuous dry removal of boiler ash contains wire tape 1 of high-strength and heat-resistant steel, made in the form of a plurality of steel plates 2 partially overlapping one another, each plate being connected to the tape by bolts 3 and nuts 4, which are connected to crossbars 5, Properly inserted into the links of the wire tape 1 “In some cases, rivets or other similar fasteners can be used instead of bolts and nuts. This open system allows the plates 2 to freely expand in any direction, thus avoiding permanent deformation and constant adjustment of the wire ribbon in the event of a temperature change.
    Each plate is provided with side plates 6, and some plates with transverse struts 7, which divide the flow into individual sections in order to eliminate the likelihood of the material slipping back on inclined sections. Thus, the plates 2 perform the load-carrying function, the wire tape 1 being driven.

    The steel wire belt 1 is driven by friction by means of a cylindrical driving drum 8 and receives the necessary tension by means of a tension drum 9, which is affected by a tensioning system (not shown). This drive system, whose principle of operation is based on friction and tension, allows the wire tape 1 to expand freely in any direction.
    The movement of the wire tape with the load is supported by smooth rollers 10, and the reverse movement of the tape (already without load) by cast-iron or steel wheels 11. The shafts 12 of the smooth rollers 10 protrude beyond the limits of the hermetically sealed steel box 13 installed in the bottom part of the boiler so that ash fell directly onto the conveyor belt in this box. The shafts 12 can be supported by bearings 14 installed in the high temperature zone and supported by the supports 15. Between the shafts 12 and the corresponding holes made in the box 13, heat resistant seals 17 are installed, which exclude the possibility of air leakage and the passage of gas, but allow free sliding shaft 12, which is necessary in view of the possible expansion of the plates. The guide and adjustment pin 18 protrudes from a hole made in the support 15 and provided with a sealing gasket 19. I
    The use of the invention makes it possible to remove and transport ashes even as large pieces without crushing them and recovering energy from unburned coal particles.
    The industrial use of dry ash is stimulated by the absence of water and unburned particles.
