[0019] Please refer to Figures 1-5 , the present invention provides a technical solution: a new type of conical centrifuge, including a drum 8, an outer shell 14 and a material distributing component 10. The drum 8 is arranged inside the outer shell 14, and the inner surface of the drum 8 is coated with a sieve mesh 7. The drum 8 is composed of a secondary cone 21 and a main cone 23. According to the different screening areas required for different materials, the screening structure of the main cone 23 can be selected alone, or a combined structure of the secondary cone 21 and the main cone 23 can be adopted, so as to change the area of the drum 8 and meet the use requirements. As shown in Figure 1 the figure, it is the combined screening state of the secondary cone 21 and the main cone 23. As shown in Figure 4As shown, it is the separate screening state of the main cone 23. The upper and lower ends of the auxiliary cone 21 and the upper end of the main cone 23 are respectively set as turned-out edge structures. Reinforcing rods 22 are fixed in the circumferential direction of the outer circumference of the main cone 23. The lower end of the auxiliary cone 21 is attached to the upper end of the main cone 23. The turned-out edge structure increases the contact area between the auxiliary cone 21 and the main cone 23. At the same time, a gasket is arranged between the two contact surfaces to increase the sealing performance of the connection. The upper end of the reinforcing rod 22 passes through the turned-out edge of the auxiliary cone 21 to the upper side. The reinforcing rod 22 can not only strengthen the structural strength of the main cone 23, but also serve as a connecting part for the auxiliary cone 21, eliminating the need to separately set a bolt connection structure. While strengthening the structural strength, it saves connection components. A locking nut 20 is arranged on the reinforcing rod 22. The auxiliary cone 21 and the main cone 23 are reliably connected together through the locking nut 20. This structure is convenient for connection and installation, bringing convenience to the work. The material distribution component 10 is arranged at the bottom of the drum 8. The material distribution component 10 includes a frustum 26. The upper end of the frustum 26 is set as a conical structure. Arc-shaped material deflecting plates 27 are arranged in the circumferential direction of the frustum 26. The upper end of the outer shell 14 is fixed with an upper cover 11 through a quick clamp 12. A feed pipe 30 is arranged at the center of the upper cover 11. The lower end of the feed pipe 30 corresponds to the center of the frustum 26. Materials enter the drum 8 through the feed pipe 30. After being distributed by the conical structure, under the high-speed rotation of the material distribution component 10, the arc-shaped material deflecting plates 27 deflect the materials towards the screen 7.

[0020] A protrusion 9 is arranged at the center of the bottom of the drum 8. A positioning groove 29 is arranged at the center of the lower surface of the frustum 26. The positioning groove 29 and the protrusion 9 play a role in positioning and matching to ensure accurate position during installation. The frustum 26 is stuck on the protrusion 9 through the positioning groove 29. The frustum 26 and the bottom of the drum 8 are connected by welding or bolt fixing, specifically selected according to actual needs. An inlet baffle 24 is arranged above the frustum 26. A fixing screw 28 is arranged between the inlet baffle 24 and the frustum 26. A material receiving port 25 is arranged at the center of the inlet baffle 24. The inlet baffle 24 plays a role in gathering materials, enabling all materials to be deflected by the arc-shaped material deflecting plates 27, improving the centrifugal separation efficiency. The lower end of the feed pipe 30 passes through the material receiving port 25.

[0021] A rotating shaft 2 is arranged at the center of the lower end of the main cone 23. A bearing chamber 4 is arranged inside the outer shell 14. The lower end of the rotating shaft 2 passes through the bearing 3 inside the bearing chamber 4, and a driven pulley 18 is arranged at the lower end of the rotating shaft 2. Through an external driving part, the driven pulley 18 is driven to rotate to realize the centrifugal screening work.

[0022] Inside the outer shell 14, an inner shell 15 is provided. The lower end of the inner shell 15 is provided as a fine material outlet 19. The undersize of the screen 7 falls inside the inner shell 15 through the holes of the rotating drum 8, and then falls downward and is discharged through the fine material outlet 19. A coarse material cavity 13 is provided between the inner shell 15 and the outer shell 14. The lower end of the coarse material cavity 13 is connected to a coarse material outlet 16. The oversize of the screen 7 moves upward under the action of centrifugal force, enters the coarse material cavity 13, and then falls downward and is discharged through the coarse material outlet 16.

[0023] A sufficient gap is left between the upper end of the inner shell 15 and the rotating drum, which will not affect the rotation of the rotating drum. There is a channel in the lower part of the inner shell 15 for liquid discharge. This structure can be adapted and modified according to the actual situation. This part is conventional technology and will not be described here.

[0024] A motor 6 is provided on the outer side of the outer shell 14. A driving pulley 5 is provided on the output shaft of the motor 6. The driving pulley 5 is connected to a driven pulley 18 by a belt. The motor 6 serves as the driving power and drives the rotating shaft 2 to rotate at a high speed through the belt drive set. The rotating shaft 2 drives the rotating drum 8 to rotate at a high speed to separate the materials.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Without departing from the spirit and scope of the present invention, the present invention has various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
