A drying and deodorizing cooling device for plastic

Abstract

The invention discloses a drying and deodorizing cooling device for plastics. The drying and deodorizing cooling device includes a bracket, a drying mechanism, a deodorizing and heat dissipation mechanism, and a cooling mechanism. The drying mechanism and the cooling mechanism are sequentially arranged on the bracket from top to bottom. A deodorizing heat dissipation mechanism and a drying mechanism are sequentially arranged on the bracket from left to right. The drying mechanism makes the plastic pellets fall from a high place and performs high-temperature drying on the plastic pellets. The water vapor deodorizes, dissipates heat and provides cooling air for the cooling mechanism. The cooling mechanism makes the plastic pellets fall from a high place and cools and air-dries the plastic pellets. The invention is scientific and reasonable, safe and convenient to use, and the drying mechanism enables The plastic pellets fall from a high place to perform free fall movement, and at the same time, the drying mechanism uses the spiral high-temperature airflow to dry the plastic pellets falling from a high place, so that the plastic pellets can fully contact with the high-temperature airflow and dry during the falling process. .

Description

technical field [0001] The invention relates to the technical field of drying, deodorizing and cooling plastics, in particular to a drying and deodorizing cooling device for plastics. Background technique [0002] In the plastic manufacturing industry, due to the degree of dryness of plastic pellets and the transparency of the final product, color purity, mechanical properties including bending, torsion, elasticity, tension index, yield, etc., and electrical properties including insulation, conductivity, etc. Therefore, before the plastic pellets are fed into the injection molding machine, extruder, blister machine or other plastic processing machinery, they must be dried accordingly. [0003] So far, many drying methods for plastic material pellets have been proposed, but the most widely used method is the dry air method, that is, the heated air is passed through the plastic pellets to remove the corresponding moisture. However, drying plastic pellets only through heated a...

AI Technical Summary

Problems solved by technology

However, drying plastic pellets only through heated airflow not only requires high energy consumption, but also takes a long time to dry, resulting in a large proportion of drying in plastic production costs.

Especially in recent years, the increase in the requirements for the removal of plastic odors has led to the need for multiple dryings of plastics, which has greatly increased the production costs of plastic manufacturers and severely restricted the development of related companies.

[0004] Moreover, after the plastic pellets are dried at high temperature, the pellets need to be cooled again, and the cooling method is mostly cooling liquid cooling, and the cooling liquid takes away the heat emitted by the plastic pellets to achieve the cooling effect, but the plastic pellets have It may be that during the cooling process, due to the high temperature generated by the accumulation, it will stick together, which will affect the use of plastic pellets, and the time to cool down with cooling liquid is relatively long
