Drying, deodorizing and cooling device for plastic

Abstract

The invention discloses a drying, deodorizing and cooling device for plastic. The drying, deodorizing and cooling device comprises a support, a drying mechanism, a deodorizing and heat dissipating mechanism, and a cooling mechanism, wherein the drying mechanism and the cooling mechanism are sequentially arranged on the support from top to bottom; the deodorizing and heat dissipating mechanism andthe drying mechanism are sequentially arranged on the support from left to right; the drying mechanism is used for dropping plastic granules from height and carrying out high-temperature drying on theplastic granules; the deodorizing and heat dissipating mechanism is used for carrying out deodorizing and heat dissipating treatment on high-temperature water vapor generated by the drying mechanism,and supplying air required for cooling to the cooling mechanism; and the cooling mechanism is used for dropping the plastic granules from height, and cooling and air-drying the plastic granules. Thedrying, deodorizing and cooling device is scientific and reasonable; the use is safe and convenient; through the drying mechanism, the plastic particles can drop from height to perform freely-fallingbody motion; meanwhile, spiral high-temperature airflow is utilized by the drying mechanism for the drying treatment on the plastic particles which drop from height; and consequently, the plastic particles can be in sufficient contact with the high-temperature airflow and dried in the dropping 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...

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
