Coating workshop steel sand shot blasting machine

Abstract

The invention discloses a coating workshop steel grit blasting machine. The coating workshop steel grit blasting machine comprises a shot blasting chamber (1), wherein a conveying roller way (2) is arranged in the shot blasting chamber (1) in a penetrating manner; the outlet end of the shot blasting chamber (1) is provided with a reverse dust removal device (4); the shot blasting chamber (1) is connected with a belt type elevator (5) through an auger mechanism; a steel grit collector (6) is arranged between the belt type elevator (5) and the shot blasting chamber (1), a steel grit filtering device (61) is arranged at the inlet end of the steel grit collector (6), a plurality of sand discharging pipelines (62) are arranged at the lower end of the steel grit collector (6), and the sand discharging pipelines (62) are provided with a quick-cutting valve (63) and a regulating valve (64). The coating workshop steel grit blasting machine is high in safety coefficient, high in working efficiency, good in dust removal effect and shot blasting effect and not easy to block.

Description

technical field [0001] The invention relates to a shot blasting machine in a coating workshop, in particular to a steel grit shot blasting machine in a coating workshop. Background technique [0002] Existing surface treatment such as rust removal for workpieces generally adopts a through-type shot blasting machine. The workpiece inlet and outlet doors are set at both ends of the shot blasting chamber, and the workpiece enters from one end of the shot blasting chamber driven by the roller transmission system. The shot blasting device installed under the shot blasting chamber performs shot blasting treatment on the workpiece, and the processed workpiece is taken out of the shot blasting chamber by the roller table transmission system. In order to increase the versatility of the shot blasting derusting machine, the diameter of the workpiece inlet and outlet of the shot blasting chamber is generally the maximum diameter of the steel pipe designed, without blocking it, it is eas...

AI Technical Summary

Problems solved by technology

In order to increase the versatility of the shot blasting derusting machine, the diameter of the workpiece inlet and outlet of the shot blasting chamber is generally the maximum diameter of the steel pipe designed, without blocking it, it is easy to cause the sand shot moving at high speed in the shot blasting chamber to splash out of the shot blasting chamber and damage the environment, and even hurt the staff, so that the safety factor of the work is not high; after the workpiece enters the shot blasting room, due to the unreasonable structural design of the shot blasting machine, the impact and friction between the steel grit and the surface of the workpiece are unbalanced , the friction area is small, and the oxide skin and rust layer on the surface of the shot blasting workpiece are not clean, which affects the post-processing and service life of the workpiece; the speed and amount of sanding cannot be well controlled, and the degree of coordination with the cleaning speed of the workpiece is not enough , it is easy to block the shot blasting room, and it needs to be shut down frequently for cleaning, resulting in low work efficiency; in addition, in the process of shot blasting and rust removal, there will be more rust, dust and other sundries removed, so only one dust collector connected to the shot blasting room is used The dust removal effect of the pipeline is not ideal. There will still be impurities in the sand shot that falls back after being lifted, which is easy to block the shot blasting machine, resulting in low work efficiency. The generated dust is easy to accumulate on the surface of the workpiece. The existing dust collector is not enough to clean the surface of the workpiece after shot blasting. When the workpiece comes out of the shot blaster, the dust deposited on the surface of the workpiece will be taken out, thereby polluting the environment

Therefore, the existing steel sand shot blasting machine has the problems of insufficient safety factor, low working efficiency, unsatisfactory dust removal effect and shot blasting effect, and easy blockage of the shot blasting machine.
