A pvc pellet production granulation device

Abstract

The invention relates to the technical field of PVC production and granulation, in particular to a PVC granule production and granulation device. The PVC granule production and granulation device comprises a base, a driving motor is installed in the middle of the upper end face of the base, a pair of symmetrical stand columns are vertically welded to the left side and the right side of the upper end face of the base, a cross beam is transversely installed at the upper ends of the stand columns, and a feeding port is formed in the right side of the upper end face of the cross beam in the vertical direction. The PVC granule production and granulation device has the beneficial effects that through the cooperation between a rotary drum and an extrusion drum, the purposes of extrusion and granulation are achieved, the granulation size is controlled through granulation rings, meanwhile, through the cooperation between condensation flowing channels and gas exhausting ports, sufficient condensation is achieved, and then the granulation forming efficiency and quality are improved; and through the relative rotation between the rotary drum and the extrusion drum, the purpose of automatic cutting-off is achieved under the cooperation of cutting-off knives, extrusion among particles caused by scraping of a scraper is avoided, and meanwhile condensers are prevented from affecting the raw materials.

Description

technical field [0001] The invention relates to the technical field of PVC production and granulation, in particular to a PVC granulation production and granulation device. Background technique [0002] PVC is a white powder with an amorphous structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77-90°C, it begins to decompose at about 170°C, and it has poor stability to light and heat. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. [0003] In the process of using PVC for granulation production, in the prior art, the cooperation of scraper and pressing plate is often used to realize granulation. In the granulation process of this method, the condensation time is decisiv...

AI Technical Summary

Problems solved by technology

In the granulation process of this method, the condensation time is decisive, and it is easy to cause the particles to stick to each other, thereby reducing the quality of granulation. At the same time, the existing pressing plate granulation device is inconvenient for filling and scraping. Scrape the through hole at the lower end of the scraper, which will cause the particles to squeeze each other. Under the action of the condenser, the raw materials on the scraper will also solidify, which is not conducive to mass production for a long time

[0004] To this end, a PVC pellet production and granulation device is provided to solve the problems that the condensation time is too short and the granulation process is complicated, which is not conducive to mass production.
