Problems solved by technology

The disadvantage of this device is: its structure is relatively complicated, especially the design of the support is more difficult
But it also has the following disadvantages: when it is used for incinerating garbage, especially unsorted garbage, it is difficult to avoid debris such as wedges, nails, steel balls, etc. in the garbage, if these debris once Embedding between the grate and the side seal compensation device will cause problems such as combustion short circuit, local overheating of the grate piece, failure of the spring at high temperature, etc., which will directly affect the effect of the compensation device to keep the ventilation gap of the grate constant, and also cause fire grate pieces, Damage to components such as springs, increasing the amount of daily maintenance of the incinerator

Embodiment

[0013] The structure of existing incinerator grate can refer to figure 1 or figure 2 , image 3 , which includes fixed grate beams 5 and movable grate beams 6 arranged in a staggered manner on the furnace body 7 with an insulating layer, and a group of fixed grate pieces 1a are connected to each fixed grate beam 5 to form A row of fixed fire grates, a group of movable fire grate sheets 1b are connected on each movable fire grate support beam 6 to form a row of movable fire grates (in image 3 In the figure, only the two-stage fixed fire grate and two-stage movable fire grate arranged in a staggered manner are shown), wherein the movable fire grate is also connected to a component that can make it reciprocate through its movable grate support beam 6 (this component is not shown in the figure) can be expressed). This existing incinerator, no matter movable fire grate or fixed fire grate, all are fixed on the body of heater with insulation layer 7 by the both sides ends of fi...

Abstract

Mechanical compensation device for incinerator grate. The thermal expansion absorbing device that can prevent the change of the grate ventilation gap caused by the thermal expansion and contraction of the incinerator grate sheet. It includes a fixed fire grate and a movable fire grate which are arranged in a staggered manner and one side of which is fixed on the furnace body. The side compensation block, the connecting piece and the sliding bracket are sequentially installed on the fixed grate beam at the end; the connecting piece includes a flat plate perpendicular to each other and a sliding block that can take the grate beam as a guide rail and can slide on it. The upper part has an outer protrusion which can be ring-embedded in the radial inner concave of the fire grate piece; the sliding bracket is slidably connected to the fixed fire grate support beam. In this way, the gap between the grate of the incinerator is constant and the air intake is stable, and because the grate piece is always attached to the side compensation block to prevent the embedding of foreign matter, it avoids short circuit of combustion and local overheating of the grate, thus reducing the amount of daily maintenance and improving the efficiency of incineration. efficiency and extend the life of the incinerator.

Description

technical field [0001] The invention relates to a thermal expansion absorbing device which can prevent the change of the ventilation gap of the grate caused by the thermal expansion and contraction of the grate of the incinerator, especially a device which can automatically compensate the change of the grate gap caused by the thermal expansion and contraction of the grate. Mechanical compensation device for incinerator grate. Background technique [0002] As we all know, when the incinerator is working, because of the difference in temperature and material between the grate piece and the furnace body structure, the gap between the grate and the furnace body will change, thereby changing the air intake space under the grate to the incineration on the grate. The ventilation gaps between the spaces lead to problems such as uneven ventilation, insufficient incineration, and decreased combustion efficiency, and also increase the difficulty of controlling the air intake volume and...
