A plastic masterbatch processing and preparation system

Abstract

The invention discloses a plastic masterbatch processing and preparation system, which includes molding equipment and drying equipment. The drying device includes a shell. The upper end of the shell is connected to a hopper. A parabolic cloth is fixedly connected to the inner wall of the shell, and a parabolic cloth is pressed below. A plurality of eccentric wheels are fixed on the rotating shaft driven by the motor; the right end of the housing is hinged to the hinge plates on both sides, the right side of the housing is connected to a discharge pipe, and the left lower end of the housing is pressed against The lifting plate is fixedly connected to the output shafts of multiple hydraulic lifting cylinders; the upper end of the casing is connected to the inlet of the fan through the air outlet hose, and the outlet of the fan is connected to the condensation box. There is a cooling inlet placed horizontally in the condensation box. Water cooling plate, the condensation box is connected with a partition, the lower end of the partition is a water collection tank, and a liquid level sensor is installed in the water collection tank. The right side of the condensation box is connected to the top of the shell through the air inlet hose, and the left side of the water collection tank is It is connected with the inlet of the recovery pump, and the outlet of the recovery pump is connected with the top of the water storage tank.

Description

technical field [0001] The invention relates to the technical field of plastic masterbatch production equipment, in particular to a plastic masterbatch processing and preparation system. Background technique [0002] Plastic masterbatch means that in the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and then measured, mixed, melted and processed by extruders and other equipment. Granules produced by extrusion, pelletizing, screening, drying and other processing processes. The masterbatch is composed of carrier resin, various fillers and various additives. The limit of additives in the masterbatch or the content of fillers is higher than that of the actual plastic. The required amount in the finished product is several to ten times higher. During the processing and molding of the masterbatch, special equipment is required to shape the plastic...

Problems solved by technology

[0003] The current masterbatch drying device basically adopts static convection heat exchange drying, the drying efficiency is low, and the drying time is long. At the same time, the water vapor carried in the hot air after drying cannot be effectively recovered, and it is generally discharged to the environment regularly. In addition, causing a certain waste of materials

[0004] At the same time, in the production process of plastic masterbatch production equipment currently on the market, the molten plastic discharged from the extruder is directly pelletized after being cooled by the water tank, resulting in unstable structures of various additives and fillers on the surface of the plastic masterbatch. It is easy to fall off from the surface of the plastic masterbatch during transportation, which reduces the product quality of the plastic masterbatch
