Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, and more specifically, to a shot blasting dust removal system. Background Art

[0002] A shot blasting machine is a casting equipment that uses high-speed projectiles thrown by a shot blasting device to clean or strengthen the surface of castings. The shot blasting machine can simultaneously perform sand falling, core removal, and cleaning on castings. During the use of the shot blasting machine, a large amount of dust is often generated, and these dusts are usually sucked by a blower into a bag filter for filtration by filter bags. The clean air is discharged into the atmosphere, and the dust on the cloth bags falls into the dust collection box at the lower part of the dust collector by mechanical vibration for regular dust removal. Although this method can play a role in dust removal, the effect is often poor only through a single filtering method, resulting in a relatively high dust content in the air discharged into the atmosphere. Therefore, in view of this, the existing structure is studied and improved to provide a shot blasting dust removal system, with the aim of achieving a more practical value. Summary of the Utility Model
