Triangle roll-over type moving grate

Abstract

The invention relates to the turn over type fire grate technology field, in particular to a triangular turn over type moving fire grate, and has a plurality of parallelly arranged fire bars. The main bodies of the fire bars are triangular prisms, chamfering or rounding is at the edge angles of the main bodies of the fire bars, axle heads concentric with the fire bars are at the two ends of the fire bars, the fire bars are rotatively connected with a furnace body through the axle heads at the two ends, axle heads at one ends of the fire bars stretch out of the furnace body, rotating plates are fixedly installed at the ends of the axle heads outside the furnace body, a rotating plate driving mechanism driving the intermittent rotation of the rotating plates is also arranged outside the furnace body, and when the rotating plate driving mechanism is in the non-working state, each fire bar has an edge surface being parallel to the connecting line of the axle center of each fire bar. The invention solves the technical problems that the existing moving fire grate structure can not enable the fuel to be fully burned, the moving fire grate is easy to fail, and the service quantity is large, etc., the invention has simple structure, and can realize automatic deslagging under the condition of not shutting down the furnace, not stopping the fire, and not opening the furnace door, the fuel is fully burned, the failure is uneasy to happen, as well as the maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of reversible grate, in particular to a triangular reversible movable grate which can be used in incinerators which require high combustion temperature for treating medical wastes and chemical residues. Background technique [0002] At present, boilers or waste incinerators all use movable grates to realize automatic slagging, and chain grates, push grates and rotary grates are more widely used. The main disadvantages of the chain grate are: First, the combustion is not sufficient. Because the fuel is on the grate, the moving grate moves forward to burn the fuel. The fuel and the grate are relatively stationary, and the direction of fire is from top to bottom. It does not have the ability to poke the fire itself, so the fire conditions are very poor, and the fuel requirements are very high. The fuel with low volatility is difficult to burn, and the fuel in the lower layer is not easy to penetrate, resulting ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to solve the technical problems that the existing movable grate structure cannot fully burn the fuel, the movable grate is prone to failure, and the maintenance amount is large. The present invention provides a triangular flip-type movable grate, which The structure is simple, it can realize automatic slagging under the conditions of non-stop furnace, non-stop fire, and no opening of the furnace door, the fuel is fully burned, it is not easy to break down, and it is easy to maintain
