Dust removal shot blasting machine

Abstract

The invention provides a dust removal shot blasting machine, and solves the problem of difficult breathing of operators caused by generation of a lot of dust during working of a traditional shot blasting machine through arrangement of a fan and a dust removing device on the shot blasting machine. Through three stages of dust removal of a first dust remover, a second dust remover and a cyclone dustremover, the dust removing effect is greatly improved, and the pollution of workshop environments by dust is prevented; the first dust remover removes the dust through collision inertia principles; afirst baffle plate and a second baffle plate are used for forming a zigzag channel to stop linear advancement of air currents; multiple first collision bars and second collision bars are used for forming multiple air current quick steering points, so that the collision frequency of the air currents with the first collision bars and the second collision bars is increased, and the separation efficiency is improved; the second dust remover uses a separation module for uniformly distributing the air currents entering the second dust remover; water forms water curtains on the surfaces of a first separation piece, a second separation piece, a third separation piece and a fourth separation piece; and water drops and the air currents relatively move to realize wet dust removal.

Description

technical field [0001] The invention relates to the technical field of shot blasting machines, in particular to a dust removal type shot blasting machine. Background technique [0002] In the casting production process, in order to remove the sand or oxide on the surface of the casting and improve the surface quality of the casting, all castings need to use a shot blasting machine. Shot blasting machine is a casting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can shake out sand, remove cores and clean castings at the same time. Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. are subject to shot blasting, which is not only to remove scale and sticky sand on the surface of castings, but also an indispensable preparation process before quality inspection of castings. However, when the existing shot blasting machine is working, a large amou...

AI Technical Summary

Problems solved by technology

However, when the existing shot blasting machine is working, a large amount of dust will be generated when it hits the surface of the workpiece, which will easily affect the treatment effect on the surface of the workpiece, and the dust will damage the air environment in the workshop after leakage, which will easily cause breathing difficulties for the operators, thus affecting their health.
