Device and method for recycling grinding material from grinding material gas jet

Abstract

The invention relates to a device and a method for recycling a grinding material from a grinding material gas jet. The device comprises an air compressor, a material storage tank, a nozzle, a magneticsorting machine, a gravity sorting machine and a grain size sorting machine; a grinding material recycling cover is arranged on a nozzle cover; a recycling pipe is connected with the grinding material recycling cover; the recycling pipe is respectively connected with a first conveying pipeline and a second conveying pipeline through a first three-way valve; the first conveying pipeline is connected with the magnetic sorting machine; a grinding material recycling port of the magnetic sorting machine is connected with a third conveying pipeline and the grain size sorting machine through a second three-way valve; the second conveying pipeline is connected with the third conveying pipeline and the gravity sorting machine through a third three-way valve; the grinding material recycling port ofthe gravity sorting machine is connected with the third conveying pipeline and the grain size sorting machine through the second three-way valve; the grinding material recycling port of the grain size sorting machine is connected with a grinding material recycling box; a discharging port of the grinding material recycling box is connected with a lateral feeding port of the material storage tank.The device and the method provided by the invention have the advantages that the grinding material use ratio of the grinding material gas jet is increased, the impurities and wastes in the jet operation are classified and treated, and the like.

Description

technical field [0001] The design of the invention belongs to the field of abrasive jets, and in particular relates to an abrasive gas jet abrasive recovery device and method. Background technique [0002] Abrasive gas jet is a new type of special processing technology, which has been widely used in drilling, cutting, deburring and other fields. In the field of metal processing, the grinding and derusting of metal workpieces are important links in industrial production and equipment maintenance. For the rust and paint removal of metal workpieces, there are problems such as large equipment is not easy to move, and paint and rust are difficult to remove. [0003] The high-pressure abrasive gas jet uses compressed air as the power to form a high-speed jet beam to spray the spray material onto the surface of the workpiece to be processed at high speed, so that the mechanical properties of the outer surface of the workpiece surface change, and then form erosion wear.

AI Technical Summary

Problems solved by technology

[0005] For the high-pressure abrasive gas jet, the abrasive particles can be reused within a certain particle size, but the waste generated by the jet eroding the workpiece contains a lot of impurities such as rust and paint, which are not easy to sieve and reuse, resulting in a large amount of abrasive waste and difficult mixing of waste Poor working environment for cleaning and discharging erosion waste into the open air
