Shot blasting waste recycling system and method

Abstract

The invention relates to the field of machining, and discloses a shot blasting waste recycling system and method, wherein the shot blasting waste recycling system comprises a shot-sand separator (10), a vibration screening device (20) and a magnetic separating device (30) which are sequentially arranged, wherein the shot-sand separator (10) is used for separating shots containing pills from the shot blasting waste; the vibration screening device (20) is used for screening the shots into pills and iron-containing ash; and the magnetic separating device (30) is used for separating iron powder from the iron-containing ash. Beneficial resources in the shot blasting waste can be effectively recycled by the following triple separating steps: firstly, carrying out shot-sand preliminary separation on the shot blasting waste by the shot-sand blasting separator; secondly, separating out the pills in the shots by the vibration screening device; and finally, separating out iron-containing resources in screen underflow of the shots by the magnetic separating device, thereby recycling the beneficial resources in the shot blasting waste to a maximum extent.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a system and method for recycling shot blasting waste. Background technique [0002] The shot blasting process is a surface treatment process that throws projectiles on the surface of the workpiece to make the surface reach a predetermined roughness. It is widely used in vehicle manufacturing and other fields. In the process of implementing the shot blasting process on the vehicle, a large amount of waste will be produced, part of which comes from the vehicle itself, such as rust, paint and dust off the surface of the vehicle, and the other part comes from the steel worn by the shot blasting surface. Scraps and waste projectiles whose diameter does not meet the requirements (for example, the diameter is less than 0.8mm). In addition, the projectiles used in the shot blasting process also fall into these waste materials. If these waste materials are treated as solid waste, a...

AI Technical Summary

Problems solved by technology

If these wastes are treated as solid waste, additional costs will be incurred, increasing manufacturing costs

In addition, these wastes contain a large amount of recyclable resources (mainly iron and steel resources), if treated as solid waste, it will cause a great waste of resources

[0003] There is a problem that the shot blasting waste cannot be effectively recycled in the prior art
