Cracking gasifier capable of uniformly mixing materials, dropping slag or discharging slag

Abstract

The invention provides a cracking gasifier capable of uniformly mixing materials, dropping slag or discharging slag. The cracking gasifier comprises a fixed disc, a slag disc, at least two driving mechanisms, at least two transmission mechanisms, at least two driving shafts and at least one rotating wheel, wherein all the driving shafts are coaxially connected together through a conical bearing ina manner that one driving shaft is nested at the periphery of the other driving shaft, and the driving shafts have three mounting positions in total; the transmission mechanisms are respectively connected with the driving shafts in a one-to-one correspondence manner so as to respectively drive different driving shafts to rotate at differential speeds; the driving shafts respectively drive the corresponding rotating wheels to rotate. After entering the cracking gasifier, materials fall into the fixed disc for cracking, and slag is formed and falls into the slag disc. The rotating wheel at thefirst mounting position rotates to mix the materials before falling into the fixed disc; the rotating wheel at the second mounting position drives the slag on the fixed disc to fall into the slag disc; the rotating wheel at the third mounting position rotates to sweep the slag on the slag disc to a slag outlet, so that slag discharging is realized.

Description

technical field [0001] The invention relates to the field of solid waste treatment, in particular to a cracking gasifier for uniform material mixing, slag falling and slag discharge. Background technique [0002] At present, most of the cracking gasifiers on the market use separate devices to achieve mixing, slag removal and slag removal respectively. The main defects of this structure of cracking gasifiers are: first, it can meet the requirements of mixing, The split structure with multiple functions of slag falling and slagging needs a large foundation, so the bottom of a general cracking gasifier needs to be dug into the ground or a high-level foundation cap should be built, which occupies a large area and requires a large investment. The cost is high; secondly, the general cracking gasifier adopts a simple slag discharge mechanism to realize slag discharge, and there is no slag discharge mechanism. When the fixed waste composition is complex and the slag particle size is...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a cracking gasifier with uniform material mixing, slagging or slagging, which solves the problem that the existing cracking gasifier adopts a split structure for mixing materials, slagging and slagging, which occupies a large area and requires a large investment. The cost is high, and the mechanism of slag falling and slag discharging is simple, which may easily cause the problem of blockage of the furnace plate
