Fire grate of household garbage incinerator

Abstract

The fire grate of the household garbage incinerator comprises a fire grate body and ventilation holes formed in the fire grate body in a rectangular array mode, two sets of insertion blocks are symmetrically and fixedly connected to the top of the fire grate body, two sets of insertion grooves matched with the insertion blocks are symmetrically formed in the bottom of the fire grate body, and a push-pull groove is formed in the side, close to the insertion grooves, of the front end of the fire grate body. The inner side of the push-pull groove is horizontally and slidably connected with a lock column penetrating through the insertion groove and the insertion block. According to the fire grate assembly structure, firstly, a lock catch type assembly structure is adopted, convenient and fast assembly treatment between fire grates can be achieved, the workload of operators is reduced, the convenience of fire grate assembly operation is improved, and therefore actual installation and use of the fire grates are facilitated; the abrasion resistance of the top face of the fire grate and the fire resistance of the bottom face of the fire grate are improved, the phenomena of fire grate scratching and heat loss fracture are reduced, and therefore the service life of the fire grate is prolonged.

Description

technical field [0001] The invention relates to the technical field of incinerator components, in particular to a fire grate of a domestic garbage incinerator. Background technique [0002] A component that stacks solid fuel in a boiler or industrial furnace and makes it burn effectively. The whole grate mainly includes two parts, the frame and the grate piece. The grate pieces are usually made of cast iron, and the necessary ventilation gaps are maintained between the pieces after assembly, and a separate ventilation room that can adjust the air volume is often set under the grate, so that the air can enter the fuel layer through the gaps for combustion. The burnt ash is discharged manually or mechanically. There are fixed type, mobile type, reciprocating type, vibrating type and downward feeding type. However, there are still deficiencies in the existing fire grate for domestic waste incinerators: when splicing the fire grate and the fire grate, the operator needs to us...
