Leakage-proof waste incineration reciprocating fire grate

Abstract

The invention discloses aleakage-proof waste incineration reciprocating fire grate. The leakage-proof waste incineration reciprocating fire grate comprises a frame, a movable frame, a crank connectingrod mechanism, two hydraulic cylinders, a connecting shaft, fire grate pieces, movable beams, fixed beams, a plurality of steel plates, idler wheels, and supporting frames; the movable frame is located in the frame, and comprises a bottom beam and a movable inclined beam which are connected, a plurality of reinforcing beams are arranged between the bottom beam and the movable inclined beam, the movable inclined beam is installed on the frame, the steel plates are arranged on the lower face of the bottom beam, the idler wheels are arranged between the steel plates and the supporting frames, the two hydraulic cylinders are located on two side plates of the frame correspondingly, both connected to the upper end of the crank connecting rod mechanism, and the lower end of the crank connectingrod mechanism is connected with the bottom beam through the connecting shaft. According to the leakage-proof waste incineration reciprocating fire grate, the hydraulic cylinders are arranged on the two sides of the fire grate, thus maintenance is convenient, heat dissipation of the hydraulic cylinders is facilitated, and the service life of the leakage-proof waste incineration reciprocating fire grate is prolonged.

Description

technical field [0001] The invention belongs to the technical field of incinerators, in particular to a reciprocating fire grate for leak-proof garbage incineration. Background technique [0002] With the development of economy and technology, waste incineration grate has become the mainstream technology for waste treatment. It has the characteristics of waste reduction and resource utilization. Therefore, it is being widely adopted and promoted under the background of increasingly strict environmental protection requirements. [0003] The existing garbage incineration grate equipment on the market usually adopts forward push reciprocating grate, and the grate is driven by hydraulic pressure. The hydraulic cylinder is usually located at the front end of the grate, which is not conducive to heat dissipation and inconvenient for maintenance; the air hole of the grate blade is usually horizontal or inclined. Arranged upwards, fuel or ash is easy to stuff into the air line, caus...

Problems solved by technology

[0003] The existing garbage incineration grate equipment on the market usually adopts forward push reciprocating grate, and the grate is driven by hydraulic pressure. The hydraulic cylinder is usually located at the front end of the grate, which is not conducive to heat dissipation and inconvenient for maintenance; the air hole of the grate blade is usually horizontal or inclined. Arranged upwards, fuel or ash is easy to stuff into the air line, causing material and ash leakage problems; there is no leakage-proof lap joint structure between adjacent grate pieces, which is easy to leak material and ash (when the fuel is plastic, it will cause serious problem of plastic oil leakage); the grate beam is made of steel pipe beam, which has poor deformation resistance
