Abstract

The invention discloses a device and method for automatic cleaning of PS and ABS waste and old plastic. The device solves the problem that the existing cleaning device cannot carry out batch cleaning of waste and old plastic and has a low impurity removal rate. The device comprises a crusher which is provided with a material inlet connected to an automatic ton bag feeding mechanism, a first rinsing tank which is connected to a discharge outlet of the crusher and is filled with a rinsing liquid comprising common salt, calcium chloride and water and having salinity of 13-15, a second rinsing tank which is communicated with the first rinsing tank and is filled with a rinsing liquid comprising common salt, calcium chloride and water and having salinity of 7-8, an environmentally friendly material treatment system communicated with the second rinsing tank, and a precipitate material treatment system communicated with the second rinsing tank. The device has a reasonable and rigorous design, is convenient for operation, has a high automation degree, realizes batch and stable cleaning of PS or ABS waste and old plastic, has a high impurity removal rate, can simultaneously clean an environmentally friendly material and non-environmentally friendly material. The device and method have high application values.

Description

[0001] technical field [0002] The invention relates to a cleaning device, in particular to a device for automatically cleaning PS and ABS waste plastics and its realization method. Background technique [0003] With the increasing consumption of plastic products, waste plastics are also increasing year by year (such as PS and ABS). At present, my country's waste plastics are mainly plastic films, plastic yarns and woven products, foam plastics, plastic packaging boxes and containers, daily-use plastic products, plastic bags and agricultural mulch films. In addition, the annual consumption of plastics for automobiles in my country has reached about 400,000 tons, and the annual consumption of plastics for electronic appliances and home appliances has reached more than 1 million tons. These products have become one of the important sources of waste plastics after they are scrapped. [0004] It is understood that in 2012, the amount of waste plastics produced in my countr...
