Color master batch production device

Abstract

The invention relates to a color master batch production device. The color master batch production device comprises a machine barrel as well as double screws arranged in a spiral groove of the machine barrel; each screw comprises a threaded section and a mixing section which is formed by a plurality of high-low staggered special-shaped blocks; the mixing section and the threaded section are fixedly connected together by a locking screw; the machine barrel is provided with heaters by bolts; a plurality of cooling water jackets are arranged among the heaters; each cooling water jacket is connected with a circulation water conveying pipe by respective water circulation pipes; a dust absorption opening is arranged in the upper part of the machine barrel; the dust absorption opening is connected with a vacuum dust absorber by a dust absorption pipe. The color master batch production device provided by the invention can effectively reduce heat generated in the shearing friction process, enables shearing to be uniform, thereby guaranteeing the stable and reliable quality of produced bar materials.

Description

technical field [0001] The invention belongs to the technical field of color masterbatch production devices, and in particular relates to a color masterbatch production device. Background technique [0002] In the process of masterbatch production and processing, screw extrusion equipment is usually used to fully mix plastics, fillers, pigments, etc., and then extrude, and then granulated by a granulator for final molding. At present, the commonly used screw extrusion equipment is a kind of mixing equipment jointly developed by foreign companies. The mixing machine includes a barrel and a screw arranged inside the barrel. The process of groove and mixing has three parts: continuous feeding, continuous mixing and continuous debinding. The characteristics of the transfer type continuous mixer are: high production efficiency, strong self-cleaning ability in the barrel and on the screw, it is very convenient to clean the barrel and screw when changing the rubber material, and i...

AI Technical Summary

Problems solved by technology

The characteristics of the transfer type continuous mixer are: high production efficiency, strong self-cleaning ability in the barrel and on the screw, it is very convenient to clean the barrel and screw when changing the rubber material, and is suitable for mixing of various rubber materials; its disadvantages It is due to the unreasonable selection and installation of the screw design (all threads with the same pitch), the selection and installation of the heater (using the liquid heating system), and the selection and installation of the cooling device (using the air cooling system), resulting in poor mixing effect. , which cannot meet the needs of production and processing. In addition, the dust particles and water vapor generated during the processing cannot be eliminated, resulting in a decline in the quality of the rubber compound.
