A two-stage reciprocating garbage incinerator inner slag breaking device

Abstract

The invention relates to a two-stage reciprocating type garbage incinerator slag crushing device, belonging to the technical field of a combustion apparatus. The two-stage reciprocating type garbage incinerator slag crushing device comprises a revolving shaft, a driving device and crushing knives, as well as a fixed seat and a telescopic oil cylinder and a transmission rack, wherein the fixed seat is arranged at the position where a backward pushing grate and a forward pushing grate are connected, the two-stage reciprocating type garbage incinerator slag crushing device is characterized in that the fixed seat consists of a left fixed seat and a right fixed seat, the revolving shaft is connected with the two fixed seats in a penetrating manner, the parts of two sides of the revolving shaft, protruding from the fixed seats, are set into a transmission gear structure, the driving device consists of a left driving device and a right driving device which are arranged in a matching manner, the transmission rack is arranged on the lower surface of the telescopic oil cylinder, the transmission rack and the transmission gear are connected in an engaged manner to do back-and-forth reciprocating movement, and the crushing knives are distributed on the revolving shaft at certain intervals and are driven by the transmission gear to do back-and-forth reciprocating movement. The two-stage reciprocating type garbage incinerator slag crushing device is a product which is smooth to use, good in crushing effect, and capable of effectively improving the garbage combustion efficiency.

Description

technical field [0001] The invention belongs to the technical field of combustion devices, and in particular relates to a slag breaking device in a two-stage reciprocating garbage incinerator. Background technique [0002] The garbage incinerator is a device for incinerating domestic garbage. It consists of a furnace body with a hopper, a feeder installed in the furnace body, a fire grate, an air chamber under the fire grate and a slag discharger. Its purpose is to carry out high-temperature combustion and carbonization of unsorted domestic waste without adding auxiliary fuel, so as to realize resource utilization, reduction and harmless treatment. However, when a large amount of unsorted garbage is incinerated at the same time, it is easy to form larger garbage slagging clusters and incompletely burned garbage clusters. These garbage clusters and slagging clusters affect the efficiency of garbage combustion, increase the heat loss of the incinerator, and It may block the s...

Problems solved by technology

However, when a large amount of unsorted garbage is incinerated at the same time, it is easy to form larger garbage slagging clusters and incompletely burned garbage clusters. These garbage clusters and slagging clusters affect the efficiency of garbage combustion, increase the heat loss of the incinerator, and It may block the slag outlet, so that the incinerator cannot operate normally

The VONROLL subsidiary of Hitachi Zosen Co., Ltd. provides a technical solution with shearing knives on the grate. Through the up and down movement of the shearing knives, the garbage on the grate is broken, which can reduce the garbage lumps and aggregates. The role of the slag, but the shearing knife is embedded in the grate, and sometimes there is metal melt or cinder on the grate, which is easy to get stuck in use

The Chinese invention patent "Disturbance Combustion Supporting Device for Garbage Incinerator", the patent number is: 200910116652.0, provides a technical solution for setting a disturbance flame retardant device under the stepped slideway. The technical solution is to rotate through a disturbance flame retardant device, or The two disturbing flame retardant devices rotate in opposite directions to break up the garbage and slagging groups, and also play a role in reducing the garbage and slagging groups. When encountering large and hard garbage or slagging clusters, it is easy to get stuck, affecting the crushing speed, or cannot be crushed repeatedly, resulting in accumulation
