Polypropylene production equipment and production process thereof

Abstract

The invention belongs to the technical field of polypropylene production and processing, and particularly relates to polypropylene production equipment and a production process thereof. A baffle is fixedly connected to the top of the base, feeding ports are evenly formed in the baffle, a rotating shaft is arranged in the center in the baffle, and a hob is fixedly connected to the outer side of the rotating shaft; a fixed cutter is fixedly connected to the inner side of the baffle at each feeding port, a top plate is fixedly connected to the top of the baffle, a first motor is fixedly connected to the top of the top plate, and an output shaft of the first motor is fixedly connected with the rotating shaft; and a feeding roller is rotationally connected to each feeding port of the base, a second motor is fixedly connected to the bottom of the base, and the second motor is in transmission connection with the feeding roller. In the prior art, when a granulator is used for granulating a polypropylene strip material, only one feeding hole is formed, and the granulating efficiency is relatively low due to thelimited processing efficiency of an extruder. The plurality of feeding ports are formed, and the directions of the feeding ports are different, so that the granulator can be matched with a plurality of extruders for use, and the granulating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of polypropylene production and processing, in particular to a polypropylene production equipment and a production process thereof. Background technique [0002] Polypropylene is a polymer obtained by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89~0.91g / cm3, it is flammable, its melting point is 189°C, it softens at about 155°C, and its service temperature range is -30~140°C. It can resist the corrosion of acid, alkali, salt solution and various organic solvents below 80 ° C, and can decompose under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc., and is also used in food and drug packaging. Polypropylene needs to be extruded, coole...
