Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, specifically relating to a shot blasting recovery device and a shot blasting machine. Background Technology

[0002] Shot blasting is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. It can simultaneously remove sand, cores, and clean castings. Most cast steel, gray cast iron, malleable iron, and ductile iron castings require shot blasting. Shot blasting removes oxide scale and adhering sand from castings, removes burrs from die castings, and achieves a decorative surface finish. It also allows for quality inspection, detecting surface defects such as subcutaneous porosity, slag inclusions, adhering sand, cold shuts, and peeling, improving the reliability of flaw detection results. The shot used in shot blasting is generally steel shot. When the shot-blasted castings are discharged from the working chamber, some shot inevitably escapes with them, resulting in wasted shot and increased production costs. Utility Model Content
