Plate link chain stepped dry slag remover

Abstract

The invention belongs to the technical field of dry deslagging systems of coal-fired boilers, and relates to a plate link chain stepped dry slag remover. The plate link chain stepped dry slag remover comprises a box of which one end is provided with a slag outlet, wherein the box is provided with a horizontal portion and an oblique portion; the other end of the oblique portion is connected with the slag outlet; the upper end face of the horizontal portion is provided with a slag inlet which is hermetically connected with the slag outlet in the lower portion of a boiler slag storage bucket; a high-temperature-resistant stepped conveying plate block for conveying slag falling off from the slag outlet to the slag outlet for dropping is arranged in the box; the high-temperature-resistant stepped conveying plate block comprises a horizontal conveying segment and a stepped ascending conveying segment; a partition baffle plate which partitions the inside of the box into a high-temperature cooling segment and a low-temperature cooling segment is arranged in the box. By adopting the plate link chain stepped dry slag remover, the defects of falling of slag, friction of a conveying device and slag, quick equipment wear, high maintenance cost and the like during conveying of large-sized slag in the slag remover are overcome, and long service life, high efficiency, large angle, stability, safety and environmental friendliness in running of the slag remover are realized.

Description

technical field [0001] The invention relates to the technical field of a coal-fired boiler dry slag removal system, in particular to a plate chain stepped dry slag remover. Background technique [0002] At present, the dry slag removal machine for coal-fired boilers in power stations mainly adopts two structural forms: metal conveyor mesh belt and crawler belt. But these two types of equipment all have certain deficiencies and cannot meet the needs of production. [0003] 1. The metal conveying mesh belt type dry slag removal machine has the following deficiencies: [0004] (1) The conveying section of the metal conveying mesh belt type dry slag removal machine adopts a metal conveying mesh and scale plate structure, and large pieces of slag are prone to roll-off due to the unstable center of gravity during operation, resulting in low conveying efficiency and large equipment loss. (2) The conveying section of the metal conveying mesh belt type dry slag removal machine adop...

AI Technical Summary

Problems solved by technology

[0009] Because the slag and the conveying plate are relatively stationary, the present invention overcomes the disadvantages of the traditional slag remover, such as the slag is easy to roll off when conveying large pieces of slag, the conveying device and the slag rub against each other, the equipment wears quickly, and the maintenance cost is high, and the long life of the slag remover is realized. , high efficiency, large angle, stable, safe and environmentally friendly operation, and can be widely used in various coal-fired boiler slag discharge systems
