Description

Technical Field

[0001] The invention relates to the technical field of plastic particle drying, in particular to a drying device for processing environmentally friendly flame-retardant plastic particles. Background Art

[0002] Plastic particles are mainly particles processed from some discarded plastics. They are mainly composed of high polymer molecules. They are formed into various plastic bags, toys and other daily necessities through hot melt injection molding and the cooperation of molds. They have extremely high practical value and economic value. In the processing of plastic particles, they generally need to be dried to remove all the moisture in them.

[0003] However, when using a plastic dryer, a blower conveys hot air into the tank to dry the moisture contained in the plastic particles. Existing dryers generally do not have a stirring component, and plastic particles with more moisture stick together, making it inconvenient to fully contact with the hot air. The undried plastic particles contain moisture, which will cause problems such as bubbles and water marks on plastic products, thereby affecting the appearance and performance of the products. When the discharged plastic particles are re-conveyed into the tank for drying, the operator is required to manually open the sealing plate installed at the lower hopper, and the manual adjustment makes it impossible to accurately adjust the moving distance of the sealing plate. When the open lower feeding port is larger, the discharge amount of plastic particles in the tank also increases. The storage space of the storage hopper is limited, and the plastic particles cannot be conveyed to the feeding screw in time, which may cause them to fall out of the storage hopper, making it inconvenient to repeatedly dry the plastic particles. Summary of the invention

The conduit 404 is fixedly connected to the tank body 1. Through the conduit 404, the hot air can be discharged into the tank body 1, and then the hot air can dry the plastic particles discharged into the tank body 1. During the drying process, the control switch of the motor 301 can be turned on, and the motor 301 drives the rotating shaft 302 fixed at its output end to rotate in the tank cover 7. Since a number of rotating racks 303 are equidistantly installed on the side wall of the rotating shaft 302, when the rotating shaft 302 rotates, the rotating rack 303 can be driven to rotate, and the first hydraulic rod 307 installed in the rotating rack 303 is started.

When the scraper 305 moves to a state of contacting the inner wall of the tank body 1, the plastic particles attached to the inner wall of the tank body 1 can be scraped off when the sliding rod 304 rotates with the rotating frame 303. At the same time, a mixing rod 306 is also installed at the bottom end of the rotating frame 303. When it rotates with the rotating frame 303, the plastic particles bonded together can be separated, so that the plastic particles are fully in contact with the hot air. Starting the second hydraulic rod 603 can drive the sealing plate 602 fixed at the telescopic end to slide in the direction away from the discharge hopper 601. The second hydraulic rod 603 is installed at the top of the fixed plate 604, and the fixed plate 604 is installed on the discharge hopper 601. The fixed plate 604 can be easily disassembled by fixing bolts. Since the discharge hopper 601 is arranged at an angle, when the sealing plate 602 slides inside it, the discharge hopper 601 can be connected with the interior of the tank body 1, so that the plastic particles in the tank body 1 are discharged into the storage hopper 501 through the discharge hopper 601.
