[0001] This utility model relates to the field of screening equipment technology, specifically a drum-type multi-stage desliming screening equipment. Background Technology

[0002] Traditional screening equipment often only achieves a single or limited screening level, and when the screening drum rotates, the material often accumulates at the bottom of the screening drum, resulting in the material in the upper area of ​​the material pile not being able to fully contact the screen, and some material failing to be effectively screened, resulting in low screening efficiency. Utility Model Content

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a drum-type multi-stage desliming and screening device.

[0004] This invention is implemented as follows: a drum-type multi-stage desliming and screening device is constructed. The device includes a base, a controller fixedly connected to the side wall of the base, and a servo motor fixedly connected to the side wall of the base. The output shaft of the servo motor drives a connecting frame to rotate and connect with the side wall of the base. A protrusion is fixedly connected to the base in the area below the circular frame. A drive shaft is rotatably connected to the center of the connecting frame. The drive shaft is fixedly connected to the center of a meshing gear, which meshes with the drive gear. The drive gear is fixedly connected to the output shaft of the drive motor, and the drive motor is fixedly connected to the side wall of the connecting frame. The side wall of the drive shaft is fixedly connected to the side wall of the circular frame. From the outside to the inside of the circular frame, a first screening frame, a second screening frame, and a third screening frame are fixedly connected, and these four sets of frames are coaxially arranged. The circular frame is rotatably connected to the side wall of the connecting frame.

[0005] Preferably, the drive shaft is hollow inside, the drive shaft is fixedly connected to the upper end of the delivery pipe, and the delivery pipe is connected to the spray pipe.

[0006] Preferably, there are four sets of spray pipes, which are respectively arranged in the screening space between the circular frame, the first screening frame, the second screening frame, and the third screening frame.

[0007] Preferably, multiple sets of valves are fixedly connected to the side wall of the circular frame away from the drive motor. These valves are connected to the screening space to facilitate the subsequent discharge of materials.

[0010] This utility model has the following advantages: This utility model provides an improved drum-type multi-stage desliming and screening device, which, compared with similar equipment, has the following improvements:

[0011] The drum-type multi-stage desliming and screening equipment of this utility model achieves multi-stage screening of materials through a first screening frame, a second screening frame, and a third screening frame. The screening aperture gradually increases in size, which can gradually separate materials of different particle sizes, improving the efficiency and accuracy of screening.

[0020] Specifically, a protrusion 4 is fixedly connected to the base 1 in the area below the circular frame 10. When the circular frame 10 rotates, the contact rod 17 on the side wall of the circular frame 10 presses against the protrusion 4. A drive shaft 6 is rotatably connected to the center of the plug-in frame 5. The drive shaft 6 is fixedly connected to the center of the meshing gear 7. The meshing gear 7 meshes with the drive gear 8. The drive gear 8 is fixedly connected to the output shaft of the drive motor 9. The drive motor 9 is fixedly connected to the side wall of the plug-in frame 5. The circular frame 10 is rotatably connected to the side wall of the plug-in frame 5.

[0021] Specifically, the drive shaft 6 is fixedly connected to the side wall of the circular frame 10. The first screening frame 11, the second screening frame 12, and the third screening frame 13 are fixedly connected from the outside to the inside of the circular frame 10, and the four sets of circular frame 10, the first screening frame 11, the second screening frame 12, and the third screening frame 13 are arranged coaxially.

[0022] Specifically, the drive shaft 6 is hollow inside, and the drive shaft 6 is fixedly connected to the upper end of the conveying pipe 14. The conveying pipe 14 is connected to the spraying pipe 15. The spraying pipe 15 is provided in four sets, and the four sets of spraying pipes 15 are respectively arranged in the screening space between the circular frame 10, the first screening frame 11, the second screening frame 12, and the third screening frame 13.

[0023] Specifically, multiple sets of valves 16 are fixedly connected to the side wall of the circular frame 10 away from the drive motor 9. The multiple sets of valves 16 are connected to the screening space to facilitate the subsequent discharge of materials. Contact rods 17 are slidably connected to the inner side walls of the circular frame 10, the first screening frame 11, the second screening frame 12, and the third screening frame 13. A return spring 18 is fixedly connected to the side wall of the contact rod 17. The bottom of the return spring 18 is fixedly connected to the circular frame 10. A crossbar 19 is fixedly connected to the side wall of the contact rod 17. Multiple sets of insertion rods 20 are provided on the crossbar 19. A rubber layer is provided in the contact area between the contact rod 17 and the circular frame 10 to improve the sealing performance of the contact between the contact rod 17 and the circular frame 10.

[0024] Specifically, the sieve apertures of the first sieve frame 11, the second sieve frame 12, and the third sieve frame 13 are set from small to large, with the third sieve frame 13 having the largest sieve aperture.

[0025] Specifically, when screening materials, the servo motor 3 is controlled to drive the circular frame 10 to rotate upward, and the material is put into the interior of the third screening frame 13 through the opening at the right end of the third screening frame 13.

As the circular frame 10 rotates, it drives the contact rod 17 to rotate to the bottom area. The contact rod 17 then presses against the protrusion 4, causing the contact rod 17 to move upwards, which in turn moves the crossbar 19. The crossbar 19 then moves the insertion rod 20, which stirs the material. As the circular frame 10 continues to rotate upwards, the contact rod 17, assisted by the return spring 18, moves upwards, causing the insertion rod 20 to move to the first screening frame 11, the second screening frame 12, and the third screening frame 13.

The water from the outside enters through the conveying pipe 14 and is then conveyed to the first screening frame 11, the second screening frame 12, and the third screening frame 13 through the spray pipe 15, which can clean the surface of the material in the first screening frame 11, the second screening frame 12, and the third screening frame 13; then the mud and water fall below the circular frame 10 and can be discharged outward through the valve 16; after screening is completed, the servo motor 3 is controlled to drive the circular frame 10 to tilt to the right, so that the material slides down to the area of ​​the valve 16, and then the respective valves 16 are opened, and the material inside can be discharged outward.
