Stirring apparatus used for producing polyvinyl chloride

Abstract

The invention discloses stirring apparatus used for producing polyvinyl chloride. The apparatus comprises a stirring chamber and a stirring device arranged in the stirring chamber, the stirring devicecomprises a stirring shaft, stirring paddles arranged on the stirring shaft and a driving member used for driving the stirring shaft to rotate; and each stirring paddle is provided with turbulent passages for guiding a fluid to flow in the rotation process of the stirring paddles to generate turbulence in the stirring chamber. According to the apparatus provided by the invention, the turbulent passages are arranged, so that when the stirring apparatus works, the stirring chamber can be in a turbulent state, materials are fully impacted, the materials are uniformly mixed, and the stirring effect is good; and the performance of the prepared polyvinyl chloride is effectively improved, and the impact resistance and bending resistance of the polyvinyl chloride are improved.

Description

technical field [0001] The invention belongs to the technical field of polyethylene processing, in particular to a stirring device for producing polyvinyl chloride. Background technique [0002] Polyvinyl chloride (pvc) is a plastic whose output is only lower than that of polyethylene (PE) in the prior art. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. [0003] The traditional preparation process for polyvinyl chloride is usually to uniformly mix the materials through a stirring device, and then extrude them through a molding machine. However, the existing mixing equipment has a poor mixing effect on materials. In the polyvinyl chloride produced by stirring, the mixing uniformity between each material is low, which greatly affects the performance of polyvinyl chloride. Its impact resistance ...

AI Technical Summary

Problems solved by technology

However, the existing mixing equipment has a poor mixing effect on materials. In the polyvinyl chloride produced by stirring, the mixing uniformity between each material is low, which greatly affects the performance of polyvinyl chloride. Its impact resistance The strength and bending resistance performance are difficult to meet the needs of outdoor use

Moreover, during the stirring process, the resistance of the stirring parts is relatively large, the loss of kinetic energy is large, and the consumption of electric energy is serious.
