Technical Field

[0002] A powder separator is a powder classification device widely used in industries such as cement, coal, mines, and chemicals. Its main function is to classify a mixture of materials with different particle sizes so as to separate materials with different particle sizes. There are various types of powder separators, such as centrifugal powder separators, cyclone powder separators, three-separation powder separators, etc.

[0003] When some existing powder separators are working, the air inside the machine cannot be recycled, and a large amount of fresh air often needs to be supplemented from the outside. When the powder separator replenishes air, the internal air flow of the powder separator may be unstable due to the entry of external air, thus reducing the powder separation efficiency. External gas may also bring in unnecessary dust and impurities, which will accelerate the wear of the equipment and increase the maintenance cost. Moreover, too frequent air replenishment will lead to a higher exhaust volume, which may cause environmental pollution. Therefore, there are certain limitations. To solve the above problems, a new type of three-separation powder separator is urgently needed to be developed. Content of the Utility Model

A blanking cylinder 9 is fixedly connected to the inner cavity of the powder separation chamber 1. A rotor 10 is rotatably connected to the inner cavity of the blanking cylinder 9. The top end of the rotor 10 is fixedly connected to the bottom end of the rotating rod 6. A medium powder discharge port 12 penetrates through the bottom of the powder separation chamber 1. One end of the medium powder discharge port 12 penetrates into the inner cavity of the powder separation chamber 1 and is rotatably connected to the bottom of the rotor 10. Four blanking holes 13 are formed at the bottom of the blanking cylinder 9. A coarse powder discharge port 14 is communicated with the bottom of the powder separation chamber 1. A wind channel 15 is communicated with the bottom of the powder separation chamber 1. A feed inlet 16 is communicated with the top of the powder separation chamber 1. Four symmetrically arranged fine powder collection cylinders 17 are communicated with the top of the powder separation chamber 1. A blower 18 is arranged on one side of the powder separation chamber 1. The air outlet of the blower 18 is communicated with the wind channel 15. The tops of the four fine powder collection cylinders 17 are commonly communicated with a circulation pipeline 19. One end of the circulation pipeline 19 is communicated with the blower 18.

[0019] In the present utility model: The driving structure 4 includes a driving motor 41. A speed reducer 42 is fixedly connected to the bottom of the driving motor 41. Through the settings of the driving motor 41 and the speed reducer 42, it plays a role in matching the rotation speed, improving the working efficiency of the equipment, and effectively reducing vibration and noise.

[0020] In the present utility model: A fixing seat 3 is fixedly connected to the top of the mounting plate 2. The top of the fixing seat 3 is fixedly connected to the speed reducer 42. Through the setting of the fixing seat 3, it plays a role in fixing and supporting the driving structure 4, avoiding the problem that the driving structure 4 falls due to vibration during operation.

[0021] In the present utility model: The bottom end of the rotor 10 penetrates to the outside of the blanking cylinder 9 and is fixedly connected with a spreading plate 11. The spreading plate 11 is located above the medium powder discharge port 12.

Then, the driving structure 4 and the fan 18 are turned on. The materials will fall into the inside of the blanking cylinder 9 and then fall onto the spreading plate 11 through the blanking holes 13. The air generated by the fan 18 will be transported into the inside of the powder selection chamber 1 through the air duct 15. At this time, the driving structure 4 will drive the driving pulley 5 to rotate. The rotation of the driving pulley 5 will drive the driven pulley 7 to rotate through the transmission of the transmission belt 8. The driven pulley 7 will drive the rotor 10 to rotate through the rotating rod 6. The rotation of the rotor 10 will drive the spreading plate 11 to rotate, so as to evenly disperse the materials. The materials will be screened by the air blown in by the fan 18, the centrifugal force generated by the rotation of the rotor 10, and the blades on the surfaces of the blanking cylinder 9 and the rotor 10. The coarse powder will continue to move downward due to inertia after being screened and finally be discharged from the coarse powder discharge port 14. The medium powder will enter the inside of the rotor 10 due to the guidance of the blades of the rotor 10 and be discharged from the medium powder discharge port 12. The fine powder will be screened and then blown into the inside of the fine powder collection cylinder 17 by the swirling wind generated by the centrifugal force, thus completing the triple classification of the materials. The air inside the powder selection chamber 1 will return to the inside of the fan 18 through the circulation pipeline 19 connected to the top of the fine powder collection cylinder 17 and then be sent into the inside of the powder selection chamber 1 by the fan 18, so as to achieve the purpose of air circulation.
