Abrasive blasting waste and old optical disk processing equipment

Abstract

The invention discloses an abrasive blasting waste and old optical disk processing equipment, comprising a transmission system, an abrasive blasting system and a sand returning system, wherein the transmission system comprises a host conveying belt and a received material transmission rack; the host conveying belt comprises a host conveying belt working part and a host conveying belt rotation part, wherein the front end of the host conveying belt working part is a feeding hole, and the rear end of the host conveying belt working part is a discharge hole; an abrasive blasting system is arranged on the host conveying belt working part between the feeding hole and the discharge hole; the discharge hole is provided with the received material transmission rack; and the lower part of the received material transmission rack is provided with the sand collection bucket of the sand returning system. The abrasive blasting waste and old optical disk processing equipment has high recovery result and is efficient and economic, and the problem that larger waste is caused because substance on the surface of the optical disk is planed main by a cutter in the common dry-method physical method can be overcome.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of waste materials, in particular to a sandblasting type waste optical disc processing equipment. Background technique [0002] With the rapid development of audio-visual, video, software and other industries, the optical disc industry is also developing continuously, and the production volume of optical discs is increasing by a huge amount every year. At present, the annual consumption of optical discs in my country alone is about 7 billion. The production and consumption of so many optical discs is bound to generate a large number of discarded optical discs every year. Over 99.97% of the base material of waste CD discs and defective discs eliminated by the manufacturing process is polycarbonate (PC). Polycarbonate is an engineering plastic with high toughness and high transparency. It has excellent properties such as heat resistance, impact resistance and stability. It is wide...

Problems solved by technology

The product quality of this kind of process treatment is good, but it will bring the secondary pollution problem of cleaning wastewater treatment discharge

The dry method is the physical method. At present, the cutter is mainly used to remove the surface layer of the disc. However, due to the difficulty in controlling the thickness of the cutter, the loss of polycarbonate together with the plating layer is generally 30%, resulting in a large waste.
