Master batch indirect cooling device

Abstract

The invention relates to the technical field of master batch production equipment, in particular to a master batch indirect cooling device which comprises a heat conduction pipe, cooling liquid and a traction wheel set. The heat conduction pipe comprises a straight pipe section and a spiral pipe section, the cooling liquid is injected into a cooling liquid tank, a circulating pump is arranged in the cooling liquid tank, the spiral pipe section is immersed in the cooling liquid, the straight pipe section is connected with a master batch extruding device and a master batch pelletizing device, and the straight pipe section is provided with an air blowing valve and a discharge port; the spiral pipe section of the heat conduction pipe is in a vertical U shape; and ribs are arranged on the outer side of the heat conduction pipe. A traditional transverse water tank structure is changed, the longitudinal space is fully utilized, and the occupied area of equipment is reduced; a plastic master batch is prevented from being in direct contact with a cooling medium, so that environmental impurity pollution is avoided; a traditional dewatering and drying link is omitted, the production cost is reduced, and cooling liquid consumption and replacement frequency are further reduced; due to the spiral heat conduction pipe, the cooling efficiency is high; and the device is convenient to maintain and clean through the air blowing valve.

Description

technical field [0001] The invention relates to the technical field of master batch production equipment, in particular to an indirect cooling device for master batches. Background technique [0002] The full name of masterbatch is plastic masterbatch, alias masterbatch, which 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 passed through an extruder, etc. Common masterbatches can be divided into filling masterbatches and functional masterbatches, such as color masterbatches, anti-fog masterbatches, etc. . [0003] In the extrusion and pelletizing process, it needs to be cooled. In the existing process, the raw material melt is usually extruded into a masterbatch plastic strip in an extrusion device, and then passed through a water tank equipped with cooling water or directly Cooling by air cooling, and then enteri...

AI Technical Summary

Problems solved by technology

[0003] In the extrusion and pelletizing process, it needs to be cooled. In the existing process, the raw material melt is usually extruded into a masterbatch plastic strip in an extrusion device, and then passed through a water tank equipped with cooling water or directly Cooling by air cooling, and then entering the masterbatch pelletizing device, these cooling methods will make the plastic masterbatch directly contact with cooling water or exposed to the air for a long time, often have many disadvantages, such as: too much moisture in the masterbatch, The masterbatch is easily polluted, the equipment occupies too much area, the cooling is not sufficient, etc.
