Description

Technical Field

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

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Plastic products, synthetic rubber and synthetic fibers form the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material that uses natural or synthetic resin as the main component, with various additives added, and can be molded into a certain shape under certain conditions of temperature and pressure, and maintains the same shape at room temperature.

[0003] The existing particle drying device for plastic product processing has poor drying effect during use, which is easy to affect subsequent production. In addition, the drying process only uses high-temperature air to heat the particles. The moisture on the outer surface of the particles evaporates after being heated and is discharged together with the hot air, which wastes heat energy and increases the drying cost. Therefore, a particle drying device for plastic product processing is urgently needed to solve the above problems. Utility Model Content

[0028] In order to improve the drying efficiency, Figures 1 to 5As shown, the present application adopts the following structure. Through the arrangement of the motor 4, the shaft 5, the spiral blade 6, the feeding barrel 7, the discharge hole 8, the spiral track 10 and the connecting track 11, the particle drying device for plastic product processing has the effect of improving the drying effect. Through the coordinated arrangement of the shaft 5, the spiral blade 6, the feeding barrel 7, the discharge hole 8, the spiral track 10 and the connecting track 11, during use, the particles to be dried are directly poured into the interior of the feed hopper 3. At this time, the particles can be transported to the interior of the drying tank 1 through the auger loader 2, and fall into the interior of the upper end of the spiral track 10, and then automatically slide to the connecting track 11. During the sliding process, high-temperature hot air is pumped into the interior of the drying tank 1 through the hot air inlet pipe 12. , the motor 4 drives the shaft 5 and the spiral blade 6 to rotate, and at this time, the particles in the connecting track 11 can be conveyed upward, and during the conveying process, some particles are discharged from the discharge hole 8.

At this time, the air pump 21 works to pump air into the interior of the drying tank 1, and the air is discharged from The air enters from the upper end of the first heat exchange tube 16, and can be preheated through the exhaust pipe 15 during the flow process, thereby increasing the temperature of the air entering the drying tank 1. A portion of the air enters the second heat exchange tube 18 from the lower end of the funnel 19. At this time, the cold air from the outside cools the spiral condenser 20, causing the water vapor to condense and be discharged. The air entering from the funnel 19 can also be preheated by the exhaust pipe 15 and the spiral condenser 20, and can also exchange energy with the hot air discharged from the exhaust pipe 15.
