Uniform drying machine for plastic particles
Technical Field
The invention relates to a dryer, in particular to a uniform dryer for plastic particles.
Background
The plastic particles refer to granular plastics, and are generally divided into more than 200 types and are subdivided into thousands of types. Common plastic particles include general plastics, engineering plastics and special plastics. The recycled plastic particles have wide application space. In daily life, the regenerated particles can be used for manufacturing various plastic bags, barrels, basins, toys, furniture, stationery and other articles of daily life and various plastic products.
The plastic particles need to be dried during production, and the drying efficiency needs to be improved through rotation or stirring during drying, most of the prior art puts a large amount of cleaned plastic particles into a vertical container for drying, for example, an invention patent with publication number CN108058409B discloses a plastic particle cleaning and drying all-in-one machine, the device is in a cleaning and drying integrated form, the plastic particles are firstly dried after being cleaned, after being dried for a period of time, an electric heating plate is started to dry the plastic particles, the plastic particles are placed on a rotary drying plate during drying, and the position randomness of the plastic particles on the drying plate is too high in such a way, and the centrifugal force is easily accumulated at a baffle plate, so that the drying efficiency is greatly influenced.
