Problems solved by technology

[0004] Since the grate is composed of three rows of modules, there will be problems of compensation for thermal expansion of the expansion joints between the modules, and a block structure of the grate is required to absorb thermal expansion and control the leakage of ash and slag and prevent stacking.

Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, a domestic waste incineration grate, because the moisture content in the waste is as high as 50%, the thickness of the waste layer is about 500mm when burning, the surface temperature of the fire grate is between 200-450°C, and the waste contains highly corrosive For leachate, there is a drop wall of about 1.6m between the three stages of drying, burning, and burnout in the length direction of the grate. When the garbage falls from the drop wall, it has a loose effect, but it will have an impact on the expansion structure. Therefore, the material is made of high-chromium cast steel with high temperature resistance, wear resistance, corrosion resistance and impact resistance.

[0021] Such as Figure 3 ~ Figure 6 As shown, a grate block structure for domestic waste incineration, the structure is to assemble a number of grate block structures with the same size between each row of grate modules; the side grate block is L-shaped in ...

Abstract

The invention relates to a domestic waste incinerator fire-grate fire-block structure. The structure is to assemble a plurality of fire-grate block structures with the same size among rows of fire-grate modules, side-face fire-grate blocks are in L shapes on the cross sections, the inner side faces of the fire-grate blocks are fixed to the inner side of a fire-grate support beam through bolts, thetop faces of the fire-grate blocks and the support beam form cavities, rib plates are arranged on the lower face sides of the side-face fire-grate blocks to form clamping grooves with the support beams, rib plates are arranged on the upper face sides of the side-face fire-grate blocks, and after symmetrical assembling, the two rib plates of the side-face fire-grate blocks form a side-face fire-grate block clamping groove. The problem of thermal expansion is solved, and fire-grate grate-by-grate modules can be additionally arranged in the width direction. According to the domestic waste incinerator fire-grate fire-block structure, the service life of the structure can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of incineration equipment, in particular to an intermediate grate block structure applied to the grate of an incinerator. Background technique [0002] With the continuous development of urban economic construction and the continuous improvement of citizens' living standards, a large amount of municipal solid waste is continuously produced every day. Therefore, the processing capacity of a single line of waste incineration mechanical grate needs to be further improved. With the increase of processing capacity, the grate area also increased. [0003] Therefore, in order to increase the daily processing capacity of the grate and increase the surface area of ​​the grate without changing the length direction, it is necessary to add a row of grate modules in the width direction of the grate. Each row of grate has a separate drive device, which can freely adjust the speed to prevent the material inequalities [0004] Sinc...
