Anti-blocking polyethylene granulating and discharging device

Abstract

The invention discloses an anti-blocking polyethylene granulating and discharging device which comprises a discharging machine shell, wherein a discharging hopper is fixedly connected to the top of the discharging machine shell, a smashing device is fixedly mounted in the discharging machine shell, a scraping device is fixedly mounted at the position, located at the bottom of the smashing device,in the discharging machine shell, and a filtering device is fixedly mounted at the bottom end in the discharging machine shell. Large-particle polyethylene particles are cut and crushed into small-particle polyethylene through the crushing device, the large-particle polyethylene particles which are completely crushed are filtered out through the filtering device, material returning and re-crushingare conducted through the material returning device, so that it is guaranteed that the discharged raw materials are all small-particle polyethylene particles and are easier to melt in a hot melting extrusion process; and the probability of blockage is reduced. The blanking speed is controlled through the speed control device, and heat in a screw extruder is prevented from being transferred into aconnecting pipe through a heat extraction device, so that materials in the connecting pipe are prevented from being molten by hot air to cause adhesion.

Description

technical field [0001] The invention relates to the technical field of polyethylene processing, in particular to an anti-clogging polyethylene granulation and feeding equipment. Background technique [0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. Insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. [0003] However, some enterprises will dissolve and remelt irregular large particles of polyethylene into regular small particles. It is not only easy to cause blockage, but also the quality after molding is poor. Contents of the invention [0004] 1. technical problem to be solved [0005] In view of the problems existing in the prior art...
