Polyvinyl chloride granule production equipment and production method thereof

Abstract

The invention discloses polyvinyl chloride granule production equipment and a production method thereof. The polyvinyl chloride granule production equipment comprises a fixed bottom plate, a shell and a stirring barrel, wherein a stirring shaft is movably arranged in the stirring barrel, the upper end of the stirring shaft penetrates through the lower wall of a protection box to be movably connected to a gearbox, a temperature control stirring frame is arranged on the outer side of the stirring shaft and the outer side of a spiral blade, the temperature control stirring frame comprises an electric heating assembly, a semiconductor refrigeration assembly is arranged on the side, away from the electric heating assembly, of the stirring shaft, an extrusion device is fixedly arranged at an outlet in the lower end of the stirring barrel and comprises a second motor, a spiral extrusion part is movably arranged at the output end of the second motor, a vacuum pipeline is fixedly arranged at the end, away from the second motor, of the spiral extrusion part, a grid is fixedly arranged at the front end of the vacuum pipeline, and the front end of a rotating rod of the spiral extrusion part penetrates through the vacuum pipeline and is fixedly provided with a cutting knife. Therefore, the equipment is high in working efficiency, small in occupied area, capable of effectively saving manpower and material resources and suitable for wide popularization.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride stirring equipment, and in particular relates to a polyvinyl chloride pellet production equipment and a production method thereof. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a polymer formed by the polymerization of vinyl chloride monomers in peroxides, azo compounds and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. Polyvinyl chloride is widely used in various building materials due to its good physical properties, chemical properties and low price. A plasticizer is a substance added to materials to improve their processability, plasticity, flexibility, and stretchability without changing the basic chemical properties of the plasticized material. It is mainly used in polyvinyl chloride resin, and its usage in PVC can account for more than 98% of the total plasticizer usage. Th...

Problems solved by technology

In the production process of polyvinyl chloride, it is often necessary to stir and mix the materials. The traditional production equipment for the production of polyvinyl chloride has a single structure and function. When the materials are processed differently, they need to be transferred to different machines.

As a result, the cost is higher, the work efficiency is lower, and the site area is larger
