Problems solved by technology

The existing fire grate is an eccentric integral fire grate, which is composed of three eccentric forward rotating active fire grates, the first forward rotating driven fire grate, and the second forward rotating driven fire grate welded to the main shaft sleeve. The positive rotating active grate, the first forward rotating driven grate and the second forward rotating driven grate are all equipped with slag discharge holes, and the integral rotary grate is driven by the motor to rotate, and the slag is removed from the furnace under the action of eccentric force. The furnace body is discharged from the slag discharge hole, but the existing grate has the following disadvantages: First, large slagging and hard objects are prone to appear in the garbage incineration. Hard slag objects are easily blocked between the grates or stuck in the slag discharge hole, resulting in unsmooth slag discharge; and the overall resistance of the grate is large, and the grate is likely to be stuck and burn out the motor or reducer; the second is that the combustion air passes through the exhaust After the slag hole enters the air from the slagging hole of the grate and the gap between the grates, it is fully mixed with the garbage material. If a large slagging hard object is blocked between the grates or stuck in the slagging hole, it will affect the combustion air intake. The amount of combustion air intake is small, which affects the mixing effect of combustion air and garbage

Abstract

The invention relates to a rotary fire grate which comprises a fixed shaft, a main shaft sleeve, a first forward driven fire grate, a second forward driven fire grate and a forward driving fire grate connected with a driving mechanism. The forward driving fire grate, the first forward driven fire grate and the second forward driven fire grate have slag removing holes. The forward driving fire grate, the first forward driven fire grate and the second forward driven fire grate are fixedly connected with the main shaft sleeve which is movably sleeved with the fixed shaft. The rotary fire grate further comprises a reverse driving fire grate. The forward driving fire grate, the reverse driving fire grate, the first forward driven fire grate and the second forward driven fire grate are arranged sequentially from bottom to top and distances are reserved between adjacent fire grates. The forward driving fire grate is connected with the driving mechanism, the reverse driving fire grate is movably sleeved with the main shaft sleeve, and the reverse driving fire grate has a slag removing hole. The rotary fire grate is good in slag breaking effect and smooth in slag discharge.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment engineering, and in particular relates to a rotary grate of a vertical pyrolysis gasification furnace. Background technique [0002] The vertical pyrolysis gasification incinerator is a new type of waste treatment equipment. Although it appeared relatively late in the waste treatment industry, it has received more and more attention due to its compact structure, low operating cost, and good tail gas emission effect. application, and with the increasing improvement of technology, the vertical pyrolysis gasification incinerator will become an important choice for small and medium domestic waste incineration power plants in the future. The grate is the core component of the vertical pyrolysis gasification incinerator. The grate mainly plays the following functions: one is the support function, holding up the garbage material to make the garbage material burn, pyrolyze and gasify in the ...
