[0002] Plastic granules are a kind of granular semi-finished products made from plastic raw materials or synthetic resins. They can be used to produce various plastic products or composite materials. There are many types of plastic granules. According to different properties and uses, they can be divided into three categories: general-purpose plastics, engineering plastics and special plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, etc. They are characterized by low cost, easy processing and wide application. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate, etc. They have the characteristics of high strength, high heat resistance and high corrosion resistance, and are often used to manufacture mechanical parts, electronic components, etc. Special plastics include thermosetting plastics, functional polymer plastics, etc. They have special physical or chemical properties and are often used to manufacture artificial organs, aerospace equipment, etc.

[0003] The prior art publication number: CN211541901U discloses a mixer for the production of plastic particles. By turning on the fan, the fan draws air into the heating chamber through the third connecting pipe through the filter head connected thereto, and the heating pipe is turned on to heat the air in the inner cavity of the heating chamber.

[0027] Preferably, the air inlet pipe 7 is a tapered pipe, the small diameter end of the air inlet pipe 7 is connected to the air inlet of the hot air blower 6, and the filter 8 is arranged at the large diameter end of the air inlet pipe 7. The design of the tapered pipe can gradually change the direction and speed of air flow, which helps to reduce the turbulence intensity of the flow, thereby improving the flow efficiency of the air flow. This helps to improve the overall efficiency of the hot air blower 6 and reduce energy consumption; when the air flow flows in the tapered pipe, as the pipe diameter gradually decreases, the wind speed will gradually increase. This change helps to reduce local turbulence and eddy currents, and further reduce energy loss.

This can provide stable support for the tank body 1, and prevent the tank body 1 from tilting or shaking during use; the plurality of support columns 2 evenly distribute the weight of the tank body 1 to each support point, and reduce the pressure on each support point. This not only enhances the durability of the support column 2, but also reduces the load on the ground or the foundation structure.

[0034] When in use, pull the pull block 24 to make the protective cover 23 rotate at the feed port through the hinge 22, and pour the material into the tank body 1 through the feed port. Then start the hot air blower 6 to blow the external air into the tank body 1 through the filter 8, the air inlet pipe 7 and the guide pipe 5, start the motor 10, and drive the stirring blade 12 to rotate through the rotating rod 11 to complete the mixing. When the mixing is completed, open the valve 3 to allow the material to flow out of the tank body 1 through the discharge port 4.

[0035] When the inner wall of the tank body 1 needs to be cleaned after long-term use, the handle 19 is rotated to make the threaded rod 18 rotate upward inside the protrusion 16 and the second fixed block through the threaded hole 17.

When the installation ring 27 is completely moved out of the arc-shaped limit plate 25 through the limit groove 26, the filter screen 8 can be cleaned.

[0037] Due to the adoption of the above technical solution, the detachable cover plate 9 can facilitate the cleaning of the inner wall of the tank body 1, thereby avoiding the inconvenience of the staff to clean the inside of the tank body 1 after long-term use, which can easily cause poor mixing effect. The arc-shaped limit plate 25, limit groove 26 and mounting ring 27 are arranged to facilitate the cleaning of the filter 8, thereby preventing the inconvenience of cleaning the filter 8 caused by the filter 8 being directly fixed to the air inlet pipe 7 during long-term use.
