Recycled plastic drying device

Abstract

The invention discloses a recycled plastic drying device. A drying box of the recycled plastic drying device adopts a hollow cylindrical structure; a driving motor is connected with the center of one end of the drying box; a material port is formed in the opposite other end of the drying box; long strip-shaped ventilating holes are densely formed in the outer circumferential surface of the drying box; outer heat-conducting fins are arc-shaped, and the outer heat-conducting fins are fixed to the outer circumferential surface of the drying box; inner heat-conducting fins are arc-shaped, and the inner heat-conducting fins are fixed to the inner circumferential surface of the drying box; the inner heat-conducting fins correspond to the outer heat-conducting fins one by one; the inner heat-conducting fins are connected with the outer heat-conducting fins through heat-conducting columns running through the circumferential wall of the drying box; the driving motor is supported on a motor supporting component; a drying box supporting component is provided with an arc-shaped groove matched with the outer circumferential surface of the drying box; the drying box is placed inside the arc-shaped groove; an electric heater is arranged inside the drying box supporting component. The recycled plastic drying device is high in drying efficiency and good in safety.

Description

technical field [0001] The invention relates to the field of plastic product manufacturing, in particular to a recycled plastic dewatering device. Background technique [0002] In order to achieve resource recycling and relieve environmental pressure, plastic products are usually recycled and reprocessed. In order to facilitate the subsequent reprocessing process, the recycled plastic is usually crushed into recycled plastic pellets before being sent to the next process. Recycled plastics usually contain high moisture content and need to be thoroughly dried before being sent to the next process for further processing. The common drying method is to use the heat dissipation fan to send the heat of the heater directly into a pile of recycled plastic particles through the pipeline, and dry the recycled plastic particles through the transfer of heat from the inside to the outside. However, such a heating method has the problem that the internal water vapor cannot be eliminated...

AI Technical Summary

Problems solved by technology

However, this heating method has the problem that the internal water vapor cannot be eliminated in time, and the drying effect is not good.

At the same time, the heat is transferred from the inside to the outside, and the internal temperature is easy to be too high, which may cause the recycled plastic particles inside to melt or catch fire, posing a safety hazard
