Shot blasting machine

Abstract

The invention discloses a shot blasting machine which comprises a rack, a shot blasting machine working chamber, shot blasting devices, a suspension mechanism, a shot collecting device, a drag box, a cope box, a lifting device and a dust removing device. The shot collecting device is provided with a shot sorting structure. The dust removing device comprises a dust removing box which communicates with the top of the upper end of the shot blasting machine working chamber through a dedusting tube. A dedusting fan is arranged on the dedusting tube. Six dust removing cloth bags are arranged inside the dust removing box. An upward air outlet pipeline is arranged at the top of the dust removing box, and air flow is made to flow out of the air outlet pipeline through the dust removing cloth bags. According to the shot blasting machine, dust can be efficiently and fast removed, sorting can be achieved in the working process, small-diameter shots and impurities are removed at the same time, and the shot blasting machine has the advantages of being fast and efficient in dust removing, timely and reliable in dust removing, free of blocking and the like; the shot blasting treatment effect and efficiency of the devices are improved; the service life is prolonged; and the working hygiene of the devices is improved.

Description

technical field [0001] The invention relates to the field of surface treatment equipment for metal parts, in particular to a shot blasting machine. Background technique [0002] Shot blasting machine is a casting equipment that uses high-speed projectiles ejected from a shot blasting device to clean or strengthen the surface of castings. The shot blasting machine hits the surface of the metal with one or more sand materials to remove some attachments on the metal surface, such as rust, or to obtain a specific surface layer through shot blasting impact. The shot blasting medium can be sand of various specifications, silicon carbide particles, small steel balls, etc. [0003] An existing shot blasting machine has the following structure: a shot blasting machine working room with a box structure, a shot blasting device is arranged on one side of the shot blasting machine working room facing the room, and a useful The suspension mechanism for hanging workpieces is equipped wit...

Problems solved by technology

But this method is cumbersome on the one hand, and on the other hand, it belongs to post-processing, which is not timely

[0006] In addition, when the shot blasting machine is working, it will generate a lot of dust when it hits the surface of the workpiece, which will easily affect the surface treatment effect of the workpiece and reduce the environmental sanitation after the dust leaks out.

In some shot blasting machines, a simple filter will be added to remove dust by filtering, but the dust removal efficiency is low and it is inconvenient to clean and replace the filter element frequently
