Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a slag chute structure of a garbage incinerator. Background Art

[0002] In a waste incinerator, waste burns on the grate. The high-temperature flue gas generated by combustion exchanges heat with the boiler's heating surface and is used to generate electricity. The remaining ash flows through a slag chute and into a slag discharger, which then discharges it into a slag pit. Due to the complex composition of waste, the ash formed after combustion contains incombustible materials such as bricks, stones, and wire. These materials easily become entangled with the ash after burning on the grate. When they fall into the slag chute, they damage the furnace walls, shortening the chute's service life and necessitating extensive maintenance. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a slag chute structure for a waste incinerator, which can effectively prevent large pieces of slag from damaging the furnace wall and improve the service life.

[0005] A furnace wall, comprising a thermal insulation casting layer and a refractory casting layer, wherein the refractory casting layer is closely attached to the inner side of the thermal insulation casting layer;

[0006] A guard plate, the guard plate being closely attached to the outer side of the thermal insulation casting layer;

[0007] A Y-shaped nail, wherein both nail teeth of the Y-shaped nail are fixedly connected to the refractory casting layer, and the end of the Y-shaped nail passes through the thermal insulation casting layer and is fixedly connected to the guard plate;

[0008] A plurality of wear-resistant plates, wherein the plurality of wear-resistant plates are closely attached to the inner side of the refractory casting layer;

[0009] A support member, wherein a first end of the support member is fixedly connected to the wear-resistant plate, and a second end of the support member is fixedly connected to the guard plate after passing through the furnace wall.

[0010] Furthermore, the guard plate includes a steel plate and a channel steel, and the channel steel is in a well-shaped shape and is tightly attached to the outer side of the steel plate and is fixedly connected to the steel plate.

[0011] Furthermore, the slag chute body is a funnel structure with an opening facing upward.

[0012] Furthermore, the angle between the guard plate and the horizontal plane is greater than 60°.

[0013] Furthermore, an inspection port is provided on the slag chute body, and an inspection door is installed at the inspection port.

[0014] Furthermore, there is a gap between adjacent wear-resistant plates.

[0015] Furthermore, there are two slag chute bodies, and the two slag chute bodies are fixedly connected and symmetrically arranged.

[0016] Beneficial effects of the present invention: The present invention provides a slag chute structure for a waste incinerator. On the one hand, the design of the Y-shaped grabbing nails and the supporting parts can improve the integrity and stability of the slag chute body; on the other hand, the presence of the wear-resistant plate can effectively prevent large pieces of slag from damaging the furnace wall, thereby increasing the service life of the slag chute body.
