Crushing machine for separating crushed material

Abstract

The invention discloses a crushing machine for separating crushed materials. The crushing machine comprises a machine body, wherein the machine body is internally provided with a crushing chamber and a separation chamber; a feeding hole is connected with the crushing chamber through a feeding channel; a heating device is arranged inside the feeding channel; the crushing chamber is internally provided with a stirring and crushing device; the stirring and crushing device comprises a fixed screw rod and a crushing screw rod; a motor is connected to one end of the crushing screw rod; spiral cutters A are arranged on the fixed screw rod; spiral cutters B are arranged on the crushing screw rod; a filtering net is arranged at the opening of the lower end of the crushing chamber; the separation chamber comprises a centrifugal pump, a separation cylinder and a separation device; the separation cylinder is electrified; the separation device comprises a material discharge groove, a positive electrode plate, a negative electrode plate and a microcomputer controller; an electrostatic separation space consisting of the positive electrode plate and the negative electrode plate is arranged below the material discharge groove. According to the crushing machine for separating crushed materials, plastic can be molten by using hot air, so that abrasion to the crushing cutters can be reduced, and the processing efficiency and the processing quality can be improved; as different crushed materials are separated by using high-pressure static electricity, the crushing machine has the characteristics of low cost, high efficiency, no pollution, and the like.

Description

technical field [0001] The invention relates to a cutting device, which belongs to the technical field of pulverizers, in particular to a pulverizer for separating broken materials. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as a laminate. With the development of the economy and the adjustment of the rural industrial structure, the market demand for plastic films in various industries in China continues to rise, and the share of plastic packaging and plastic packaging products in the market is increasing, especially composite plastic flexible packaging. Widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great benefits to people's lives. convenience. ...

AI Technical Summary

Problems solved by technology

The separation process of waste plastics manual sorting, two-stage crushing, magnetic separation, clear water flotation, and brine flotation. Although the present invention can realize the separation of mixed plastics, the whole sorting process is cumbersome; The salt water tank is used for specific gravity differential separation. Since the density ranges of many plastics overlap or the characteristic densities are very similar (for example, the characteristic densities of PVC and PET are 1.39g·cm-3 and 1.37g·cm-3 respectively), so simply Relying on density differences has low sorting efficiency, and the products need to be dehydrated and dried, and there are environmental pollution control problems such as sludge and wastewater treatment.
