Plastic particle drying machine

Abstract

The invention discloses a plastic particle drying machine. The plastic particle drying machine comprises a stand, wherein a cylindrical material barrel is axially and rotationally mounted on the stand; a charging port is formed in one end of the material barrel; a feeding device is mounted at the charging port; a lamp box which extends into the material barrel from the charging port and can emit light to heat a material is mounted on the stand; a fan is further arranged on the stand; an air exhaust pipe which is communicated with the material barrel to exhaust air in the material barrel is connected to the fan; a limiting device which is used for limiting the axial position of the material barrel is arranged at each of two ends of the material barrel; a discharging port is formed in the barrel wall of the material barrel; a cover plate is mounted at the discharging port and is driven to close or open the discharging port by a cover plate driving device. The plastic particle drying machine can be used for drying plastic particles, and is good in complete drying effect, high in heat energy utilization rate, and stable and reliable to work.

Description

technical field [0001] The invention relates to a dryer, in particular to a plastic particle dryer Background technique [0002] In order to improve the quality of plastic products, their raw materials are generally processed into plastic particles. Loose plastic particles are susceptible to moisture when exposed to air. The chemical properties of plastic products made of damp plastic raw materials will be significantly reduced, which will affect the quality of the product. Therefore, loose plastic particles need to be dried before being processed into plastic products. The common method is to use a heat dissipation fan to pass the heat of the heater through The pipe feeds directly into a pile of loose material where it is dried. The heat will diffuse in the loose raw materials, and the peripheral raw materials will be heated later, and the raw materials are in close contact with each other, which reduces the contact area between the heat and the raw materials, and the wat...

AI Technical Summary

Problems solved by technology

The heat will diffuse in the loose raw materials, and the peripheral raw materials will be heated later, and the raw materials are in close contact with each other, which reduces the contact area between the heat and the raw materials, and the water vapor generated after the raw materials are heated cannot be removed in time. The disadvantages of long drying time, large energy waste and low energy utilization rate
