Polyvinyl chloride cable material drying equipment

Abstract

The invention discloses polyvinyl chloride cable material drying equipment. The polyvinyl chloride cable material drying equipment comprises a shell, a cover plate is arranged on the shell. A microwave heater is arranged in the shell, and a cold air pipeline is connected to the side wall of the shell in a penetrating mode. According to the polyvinyl chloride cable material drying equipment, through the cooperation of a servo motor, a rotating pillar, a belt, a bottom plate, a base and a fixing pillar, a fixing rod is pulled out towards the outer side of a squeezing groove, a cable material isput between the fixing rod and the fixing pillar, the fixing rod is loosened, the cable material is clamped under the action of the first springs, the servo motor is started, the rotating pillar is driven to rotate through the belt, then the fixing pillar on the base is made to rotate, and moisture on the surface of the cable material is separated under the centrifugal force. By means of the device, not only moisture can be separated through centrifugation, drying is faster, but also materials are heated from the inside to the outside at the same time, the inner-outer temperature difference ofthe materials is very small, drying is fast and high in efficiency, the drying period is greatly shortened, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride, in particular to a polyvinyl chloride cable material drying equipment. Background technique [0002] Polyvinyl chloride is a high-viscosity, heat-sensitive polymer thermoplastic material, and it is one of the most widely used plastics at present. PVC cable material is made of polyvinyl chloride series resin as raw material, adding plasticizer, stabilizer, flame retardant and other special processing aids, etc., after mixing, extruding, plasticizing and granulating, PVC Vinyl cable materials need to use drying equipment in the processing engineering. However, when drying PVC cable materials in the prior art, since most of the water is on the surface of the material, it takes a lot of time to dry the water on the surface, which is not conducive to drying, and conventional vacuum drying equipment uses steam to dry. Heating needs to be heated from the outside to the inside, the heating s...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to propose a drying equipment for polyvinyl chloride cable material to solve the problem in the prior art that when drying polyvinyl chloride cable material in the prior art, it takes a lot of time because most of the water is on the surface of the material. Drying the water on the surface is not conducive to drying, and conventional vacuum drying equipment uses steam for heating, which needs to be heated from the outside to the inside, the heating speed is slow, and a large amount of coal is consumed
