Medical PVC particle production system

Abstract

The invention relates to a medical PVC particle production system. The system comprises a hot mixing machine, a cold mixing machine, an extruding machine, a granulating machine and an air supply system; the hot mixing machine is arranged at the upper part of the cold mixing machine; the extruding machine is arranged at the lower part of the cold mixing machine, and is connected with the granulating machine and the air supply system in sequence; a discharge port of the hot mixing machine is vertically formed in the upper part of a feed port of the cold mixing machine; a discharge port of the cold mixing machine is vertically formed in the upper part of a hopper of the extruding machine; a stirring device is arranged in the hot mixing machine; a cooling device is arranged in the cold mixing machine; a screw rod conveying module is arranged in the extruding machine; and a heating device is arranged out of the screw rod conveying module. The medical PVC particle production system is high in automation degree, is provided with time and temperature controllers on the hot mixing machine and the cold mixing machine for guaranteeing material stirring and cooling effects to lay foundation for subsequent PVC particle production, and is provided with a vacuum purifying device on one side of the extruding machine for effectively reducing molecular groups and impurities in materials to guarantee subsequent production quality.

Description

technical field [0001] The invention relates to the production field of medical PVC granules, in particular to a production system of medical PVC granules. Background technique [0002] PVC material is polyvinyl chloride, which is a white powder with an amorphous structure. It is often used to make pipe fittings, industrial packaging, daily necessities, etc. It can also be used to make acid and alkali resistant hoses, cable sheaths, insulation layers, and medical infusion tubes, etc. medical supplies. Medical PVC pellets require multiple steps in the production process, but most of the existing production equipment systems have low automation, low production efficiency, and product quality cannot be guaranteed, which affects the economic benefits of enterprises. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a production system of medical PVC pellets with strong continuity and high production efficiency. ...
