Waste plastic crushing device

Abstract

The invention relates to a waste plastic recycling technology field, and discloses a waste plastic crushing device which comprises a cylindrical crusher, a first belt conveyor and a second belt conveyor; the upper end of the crusher is provided with a feed port, the lower end of the crusher is provided with a discharge port, one end of the crusher is connected with a motor, and an output shaft of the motor is connected with the crusher; the feed port is connected with the first belt conveyor, and the discharge port is connected with the second belt conveyor. The waste plastic crushing device has the advantages of low cost, simple structure and convenient use; an iron brush can sweep raw material of the feed port into the crusher, crushed raw material can be carried away timely, concentration of the raw material in the crusher can be avoided, the service life of a blade of the crusher is prolonged, and the number of replacement times is reduced.

Description

technical field [0001] The invention relates to the technical field of waste plastic recycling, in particular to a waste plastic crushing device. Background technique [0002] Food packaging bags, agricultural film, woven bags, beverage bottles, plastic basins, barrels, toys, old sandals, household appliance casings, and waste materials in the plastic molding process, etc., the white pollution formed by a large amount of waste directly threatens human dependence environment to survive. As a measure to save energy and protect the environment, the recycling of waste plastics is getting more and more attention. Especially in developed countries, the work started early and has already received obvious benefits. Petroleum reserves are dwindling, and recycled plastics also mean oil regeneration. The use of waste plastics to melt and granulate can alleviate the contradiction between the supply and demand of plastic raw materials, and can save a lot of foreign exchange for the cou...

Problems solved by technology

[0003] In the recycling system of waste plastics, the crushing link is a key step. The existing waste plastics crushing technology is one-time crushing into sheets. Since the sheets need to reach a certain size, the sheets stay in the crusher for a long time. The formed sheet cannot be discharged in time under the wrapping of waste plastics and large sheets, there are many wear debris, the surface finish of the sheet is reduced, the wear degree of the blade of the crusher is increased, the blade is replaced frequently, the production time is prolonged, and the energy consumption is increased.
