High-quality nonmetallic sand-blasting abrasive circulating device

Abstract

The invention discloses a high-quality non-metallic sandblasting abrasive circulation device. In the process of recycling the sandblasting abrasive, it is also prepared after separation of fine powder and large particles, magnetic separation, particle size separation, and density separation. Use a dehumidifier to send the dry air to the material storage device and the sandblasting host to prevent the abrasive from getting damp, so that the abrasive sprayed from the spray gun is of high quality with no dust pollution, uniform particle size, uniform density, no moisture, and no agglomeration. High-quality sandblasting abrasives ensure that precious workpieces will not be damaged due to the influence of abrasives during the sandblasting process. The device includes a sand blasting room, the bottom of the sand blasting room passes through the sand suction pipe and the sand return device, the iron removal device, the material storage device 1, the particle size separation device, the specific gravity separation device, the sand lifting device, the material storage device 2, the spraying The sand host is connected in series, and the sand blast host performs sandblasting treatment on the surface of the workpiece through the sand valve sandblasting tube spray gun assembly. The material storage device 1, the material storage device 2, and the blasting host are respectively communicated with an air dehumidifier that provides dry air.

Description

technical field [0001] The invention relates to an abrasive circulation device for sandblasting equipment, especially for sandblasting treatment of carbon fiber products in the field of glass fiber reinforced plastics and aerospace, or an abrasive circulation device for sandblasting and paint removal of automobiles and aircrafts, in particular to a high-quality non-metallic sandblasting abrasive circulation device . Background technique [0002] The sandblasting machine is a mechanical device that sprays abrasives onto the surface of the workpiece with the power of compressed air to perform various surface treatment processes such as paint removal and stain removal. Different abrasives can be selected according to the surface treatment requirements of the workpiece, including metal abrasives or non-metallic abrasives. . Usually, impurities, oxide layers, variegated colors, sludge, dirt, paint and other attachments are treated on the surface of the workpiece. [0003] Carbo...

AI Technical Summary

Problems solved by technology

When the existing equipment blasts the surface of the aircraft and carbon fiber products, it is easy for sand, welding slag, iron filings and other particles larger than resin sand to be mixed into the circulation device of the abrasive, which will damage or damage the substrate when it is sprayed on the surface of the workpiece. In addition, when the air is humid during the rainy season, the abrasive is easy to agglomerate and has poor fluidity, which affects the quality of sandblasting
