Uniform drying device

Abstract

The invention discloses a uniform drying device and relates to the technical field of plastic machinery. The uniform drying device comprises a drying box, a support frame, a receiving box and a hot-blast air device, wherein the drying box comprises a box body and a discharging end cover, and the discharging end cover is matched with the lower end of the box body; a feeding hole is formed in the side face of the box body; the receiving box is arranged below the drying box; the drying box and the receiving box are fixed on the support frame; the hot-blast air device is connected onto the upper end of the drying box; the hot-blast air device comprises a shell, a radiating fan, a heating wire and a plurality of blast tubes; the upper ends of the blast tubes are fixed with an air outlet of the radiating fan; a plurality of radiating holes are formed in the lower ends of the blast tubes; a drive motor for driving the hot-blast air device is further mounted on the support frame. A plurality of blast tubes and a plurality of radiating holes are formed, and the drive motor can drive the hot-blast air device to rotate relative to the drying box, so that the blast tubes can stir plastic particles, the plastic particles can be heated more uniformly when dried, and the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of plastic machinery, in particular to a plastic drying device. 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, because the heat is continuously absorbed by the plastic particles during the diffusion, so that the closer to the center of the plastic particles, the higher the t...

AI Technical Summary

Problems solved by technology

The heat will diffuse in the loose raw materials, because the heat is continuously absorbed by the plastic particles during the diffusion, so that the closer to the center of the plastic particles, the higher the temperature, which will lead to uneven heating and the drying efficiency of the plastic particles is not high
