Strip steel through-type shot blasting cleaning machine

Abstract

The invention relates to a shot blasting cleaning machine and in particular relates to a strip steel through-type shot blasting cleaning machine, belonging to the technical field of shot blasting cleaning equipment. The strip steel through-type shot blasting cleaning machine comprises an elevator, a maintenance platform, a shot-sand separator, an upper screw conveyer, a cleaning chamber body, a lower screw conveyer, a base and a water curtain dust removal device, wherein the cleaning chamber body fixed on the base is formed below the shot-sand separator and is communicated with the water curtain dust removal device by virtue of a dust removal pipe; a dust removal fan is fixed at the upper end of the water curtain dust removal device and is communicated with the water curtain dust removal device; a cyclone dust collector is arranged in the middle of the dust removal pipe; the cleaning chamber body is connected with the lower part of the elevator by virtue of the lower screw conveyer; and a longitudinal auger is arranged in the cleaning chamber body. According to the strip steel through-type shot blasting machine disclosed by the invention, coiled strip steel can be continuously subjected to continuous shot blasting, and the cleaning machine can be applied to cleaning of strip steel with various sizes and specifications and is wide in application range; and moreover, a secondary dust removal system consists of the cyclone dust collector and the water curtain dust removal device, the dust removal effect is excellent, and the environmental pollution degree is low.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to a strip passing type shot blasting machine, which belongs to the technical field of shot blasting equipment. Background technique [0002] The existing surface rust removal technology in the domestic strip steel industry is pickling, and it is difficult to dispose of the waste acid solution, which brings serious pollution to the surrounding environment. The special shot blasting machine for strip steel uses the high-speed fine granular steel shots projected by the shot blasting machine to hit the surface of the strip steel, so as to achieve the effect of derusting the surface of the strip steel. [0003] The strip steel shot blasting machine is mainly used for derusting the surface of the annealed carbon strip steel or stainless steel strip to clean the scale, and can also be used for derusting and cleaning the surface of the annealed carbon alloy strip steel. The pre-process of surfac...

Problems solved by technology

[0004] The traditional strip steel shot blasting machine usually uses the steel plate to be conveyed on the roller table for blasting. However, due to the small width of the strip steel and the impact of the conveying device on the cleaning effect, there are few special equipment for strip steel shot blasting cleaning, often by means of Other shot blasting equipment or methods to clean the strip

[0005] Traditional dust collectors mostly use bag and filter cartridges for dust removal, which are easy to block during use

The service life of the dust removal system is short, the maintenance is frequent, and the maintenance workload is heavy; the maintenance will cause secondary pollution to the environment
