Description

Technical Field

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

[0002] Plastic granules refer to granular plastics. Common plastic granules include general-purpose plastics, engineering plastics, special plastics, etc. Before processing plastic granules, it is often necessary to use a drying device to dry the water droplets on the surface of the plastic granules;

[0003] When using the existing plastic particle drying device, a stirring mechanism is usually used in conjunction with a heating mechanism to dry the plastic particles in the device. However, in actual use, we found that the entire drying process can only dry the entire surface of the plastic particles in the device. It is still difficult to ensure that the water droplets on each plastic particle are dried even with the stirring mechanism. At the same time, some plastic particles will stick to the inner wall of the device during the drying process, which makes it difficult to heat and dry these plastic particles and subsequently recycle them. Therefore, how to solve this problem is what we need to consider. Utility Model Content

[0023] Among them, a circular inner groove 12 is opened at the upper end of the rotating shaft 11, and a hot air blower 3 is installed at the upper end of the shell 1 (this is the prior art, and the hot air blower 3 is mainly composed of three parts: a blower, a heater, and a control circuit). The air outlet end of the hot air blower 3 is connected with an air duct 4, and the other end of the air duct 4 is connected to the circular inner groove 12 through a rotating joint 5. The lower end of the rotating shaft 11 extends to the inner bottom of the shell 1, and the left and right sides of the rotating shaft 11 are fixedly connected with C-shaped connecting pipes 13. Each C-shaped connecting pipe 13 consists of a horizontal pipe at the upper end, a vertical pipe in the middle, and an inclined pipe at the lower end. The two horizontal pipes The opposite sides of the two vertical pipes are connected to the circular inner groove 12, and the opposite sides of the two vertical pipes are provided with a plurality of air outlet holes 14, and the aperture of each air outlet hole 14 is smaller than the diameter of the plastic particles. When the hot air blower 3 is turned on, the hot air will be discharged along the plurality of pipes and finally through the plurality of air outlet holes 14, thereby drying the inside of the entire plastic particles. The side of the two vertical pipes away from the rotating shaft 11 and the side of the two inclined pipes away from the rotating shaft 11 are both in contact with the inner wall of the shell 1, and the plastic particles remaining on the inner wall of the shell 1 can be scraped off during rotation, thereby effectively improving the drying and recycling efficiency of these plastic particles;

[0024] Among them, a plurality of stirring rods 15 are horizontally symmetrically fixedly connected to the rotating shaft 11, and a spiral blade 16 is fixedly connected to the rotating shaft 11. The spiral blade 16 is located above the discharge port 10.
