Plate chain slag remover bending angle limit protector

Abstract

The invention relates to a bent corner limit protector for a chain plate slag remover. The bent corner limit protector comprises an arc plate, and is characterized in that a positioning base fixed to the side wall of a slag remover groove body is arranged above the arc plate; a positioning plate with a bolt hole is arranged on the positioning base; a dual-head bolt bar fixedly connected with the positioning plate through a locking nut is arranged on the lower part of the positioning plate; the top of the dual-head bolt bar penetrates through the bolt hole; a tightness adjusting nut, a baffle sheet and a reset spring sequentially sleeve the lower part of the dual-head bolt bar; the lower end of the reset sprig is inserted into a groove in the upper surface of the arc plate; a normal fixing base and a U-shaped limit plate are arranged at each of the two ends of the arc plate; each normal fixing base consists of a T-shaped upright surface which slides in the manner of being relative to the U-shaped limit plate and a T-shaped top surface which limits the normal relative displacement of the U-shaped limit plate. The problem that a chain of the current chain plate slag remover is easily blocked by foreign matter is solved, the limit effect to the chain at a bent corner of the slag remover can be guaranteed, the chain can be protected when the foreign matter enters the slag remover, and the failure rate of the slag remover is obviously reduced.

Description

technical field [0001] The invention relates to slag removal equipment, in particular to a bend angle limit protector for a plate chain slag remover. Background technique [0002] At present, the boiler slag remover is generally not equipped with a backup system. When the boiler is in production in winter, once a problem occurs in the slag remover, it will inevitably cause the boiler system to stop production. If the shutdown time is too long, it will cause other accidents such as frozen pipes and equipment damage. The failure rate of slag removal equipment is very important. The existing boiler slag remover generally adopts the plate chain slag remover, and the most common mechanical failure of the plate chain slag remover is foreign matter stuck chain and so on. The part with the highest probability of foreign matter jamming is the corner of the slag remover. The traditional limit method for the corner of the slag remover is to weld two arc-shaped plates on the side wall ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a plate chain slag remover bend angle limit protector that solves the problem of foreign matter jamming in the existing plate chain slag remover, which can ensure the limit of the chain at the bend of the slag remover. position, and can protect the chain when foreign matter enters the slag remover, significantly reducing the failure rate of the slag remover
