Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing and drying, in particular to a drying device for plastic particle processing. Background Art

[0002] At present, the drying device for the production and processing of plastic particles is a device used to dry the surface moisture of the raw materials for the production of cleaned plastic products or the plastic products after surface cleaning to facilitate their subsequent processing or transportation and sales. It has been widely used in the field of plastic product production.

[0003] When some existing drying devices are working, most of them place the particles into a tank, then use a stirring mechanism to stir the particles, and then use a hot air blower to input hot air into the tank to achieve the purpose of drying. For example, the prior art discloses a drying device for plastic particle processing and molding with application number CN202220022724.6. By setting a connection relationship between a rotating motor, a rotating column, a rotating rod and a box body, the rotating rod is driven to rotate by starting the rotating motor, so that the plastic particles are stirred, which is convenient for fully contacting the moisture on the plastic particles with the hot air, and is convenient for improving the drying efficiency. However, there is a large gap between the upper and lower rotating rods, which makes it easy to have a stirring dead angle, making it difficult to stir particles at different levels, affecting the drying efficiency. Secondly, when drying the ultrasonic particles, moisture will be generated, and the moisture contains a large amount of heat. If it is directly discharged, it will cause energy waste, which is not in line with the concept of energy saving and environmental protection. Utility Model Content
