[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] Existing metal powder processing collection and drying devices typically include a heating chamber, a discharge pipe, and a stirring device. The heating chamber is heated by an electric heating wire, and the metal powder is mixed by the stirring device to ensure that the powder is heated evenly. After drying, the powder is discharged and collected through the discharge pipe inserted at the bottom of the heating chamber.

[0024] Example 1

[0025] Please refer to Figures 1-5 A mixing device for various plastic granules includes a tank 1, an end cap 2, and a limiting seat 3. The end cap 2 is bolted to the top of the tank 1 for support and limiting. The limiting seat 3 is welded to the middle of the tank 1. A sealing cap 4 is bolted to the top of the limiting seat 3, and a servo motor 5 is bolted to the top of the sealing cap 4. A connecting pipe 6 is inserted into the side wall of the limiting seat 3. A blower 7 is fixed to the side wall of the end cap 2 near the limiting seat 3, and a flexible hose 8 is inserted into the top of the blower 7. A vertical rod 10 is fixed to the output end of the servo motor 5 via a coupling. Several sets of stirring rods 11 are sleeved on the outer surface of the vertical rod 10. Starting the servo motor 5 can drive the vertical rod 10 and the stirring rods 11 to rotate for mixing. The plastic granules and the stirring rod 11 have several nozzles 12 inserted into their side walls. The stirring rod 11 and the nozzles 12 are symmetrically distributed. The external dimensions of the stirring rod 11 are adapted to the internal dimensions of the tank 1. The vertical rod 10 is fitted with a connecting seat 16 near the outer surface of the servo motor 5. The side wall of the connecting seat 16 has a groove 17, and the inner side wall of the groove 17 has a connecting groove 18. The connecting groove 18 is connected to the nozzles 12 to facilitate air circulation and improve the stability of the stirring rod 11 during rotation. The limiting seat 3 has a first slot 19 in the middle for the connecting seat 16 to rotate. The first slot 19 is connected to the connecting pipe 6. The other end of the hose 8 is inserted into the middle of the connecting pipe 6 to improve the stability of gas circulation.

[0026] A filter 13 is threadedly connected to the input end of the blower 7 side wall. A filter element is snapped into the middle of the filter 13. The filter element is made of non-woven fabric to filter impurities in the air, improving the safety and stability of the air intake. The top of the limiting seat 3 has a second slot 20 that communicates with the first slot 19. The surface of the limiting seat 3 near the second slot 20 has four threaded holes symmetrically provided for bolt connection. The bottom end of the sealing cover 4 is fixed with a sealing ring 21. The bottom end of the sealing ring 21 has an anti-slip groove. The external dimensions of the sealing ring 21 are adapted to the internal dimensions of the second slot 20. The surface of the sealing cover 4 has four limiting grooves 22. The four limiting grooves 22 are adapted to the threaded holes for bolt insertion, improving the convenience of installation and positioning of the limiting seat 3 and the sealing cover 4. The limiting grooves 22 pass through the sealing cover 4 in sequence, improving the sealing performance of the limiting seat 3 installation.

[0027] A discharge pipe 9 is inserted into the middle of the bottom of the tank body 1. A valve is installed in the middle of the discharge pipe 9. The mixed plastic granules can be discharged by opening the valve. Four support legs 15 are symmetrically fixed at the bottom of the tank body 1. A feed hopper 14 is inserted into the surface of the end cover 2. The feed hopper 14 is funnel-shaped and passes through the end cover 2 to facilitate the operator to add plastic granules.

[0028] When using this multi-plastic granule mixing device, the operator first connects an external power source and pours the plastic granules to be mixed into the tank 1 from the feed hopper 14. Then, the servo motor 5 is started to drive the stirring rod 11 and the nozzle 12 to rotate, thereby mixing the plastic granules. When the mixing is complete, the operator opens the valve installed in the middle of the discharge pipe 9 to allow the plastic granules to be discharged under gravity. When some plastic granules are adsorbed on the inner wall of the tank 1, the operator starts the blower 7 to deliver air through the connecting pipe 6 to the first slot 19. The gas then enters the middle of the stirring rod 11 through the groove 17 and the connecting groove 18 and is evenly discharged through the nozzle 12, thereby cleaning the inner wall of the tank 1. The servo motor 5 is started to drive the vertical rod 10 and the stirring rod 11 to rotate, thereby expanding the cleaning range and causing the adsorbed plastic to be blown off and discharged through the discharge pipe 9. This improves the cleaning efficiency of the tank 1 of the multi-plastic granule mixing device, thereby reducing pollution and improving the subsequent mixing quality.

[0029] Furthermore, considering the presence of impurities and pollution in the air, the internal filter element of filter 13 filters out impurity particles, thereby improving the safety of the intake air.

[0030] Furthermore, considering that air leakage from the limit seat 3 would affect the purging quality, the sealing ring 21 was engaged in the middle of the second slot 20 to improve the sealing performance of the connection between the limit seat 3 and the sealing cover 4.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
