DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0026] Refer to Figures 1 - 6, A ultrafine powder processing device, including a base 1 and a workbench 2. Multiple symmetrically arranged foot pads are fixedly connected to the lower end surface of the base 1. A rotating motor 3 is provided on the lower end surface of the base 1. A rotating shaft 4 is provided on the rotating motor 3. One end of the rotating shaft 4 away from the rotating motor 3 penetrates the base 1. One end of the rotating shaft 4 away from the rotating motor 3 is fixedly connected to a centrifugal disc 18. The centrifugal disc 18 fits the upper end surface of the base 1. By means of the centrifugal disc 18, the falling materials are received, so that these materials can move to the edge of the hopper-shaped cavity 5 under the action of centrifugal force when rotating with the centrifugal disc 18, and then smoothly cooperate with the workbench 2 and the base 1 to complete the grinding work, avoiding the accumulation of materials at the central position and affecting the grinding efficiency. A hopper-shaped cavity 5 is provided on the lower end surface of the workbench 2. An inlet 6 is provided on the upper inner wall of the hopper-shaped cavity 5. A feed hopper 16 is provided on one side wall of the workbench 2 away from the base 1. The feed hopper 16 is communicated with the inlet 6, making it more convenient for the staff to feed materials. One end of the rotating shaft 4 away from the rotating motor 3 is fixedly connected to a connecting frame 7. The connecting frame 7 is fixedly connected to the inner wall of the inlet 6, so that the workbench 2 can be controlled to rotate relative to the base 1, and then the ultrafine powder grinding work is completed. Multiple lifting grooves 8 are provided on the inner wall of the inlet 6. Multiple lifting blocks 9 are slidably connected in the multiple lifting grooves 8;
[0027] Lifting pull rods 17 are fixedly connected to the upper end surfaces of the multiple lifting blocks 9. The multiple lifting pull rods 17 are respectively slidably connected in the multiple lifting grooves 8. By means of the lifting pull rods 17, it is convenient for the staff to pull the lifting blocks 9 for taking and placing work. At the same time, the lifting pull rods 17 can block the lifting grooves 8 to prevent materials from entering the lifting grooves 8 and affecting the processing work. The multiple lifting blocks 9 are jointly fixedly connected to a dividing mesh plate 10. In this way, the dividing mesh plate 10 can be disassembled, which is convenient for the staff to clean. An initial processing component is provided on one side of the workbench 2 away from the base 1. The initial processing component includes multiple suspension columns 11. The suspension columns 11 are arranged on the corresponding top beams to complete the suspension and fixing work. The multiple suspension columns 11 are jointly fixedly connected to a suspension seat 12. A hydraulic cylinder 13 is provided on the upper end surface of the suspension seat 12. A hydraulic column 14 is provided on the hydraulic cylinder 13. One end of the hydraulic column 14 away from the hydraulic cylinder 13 penetrates the suspension seat 12 and is fixedly connected to a pressing table 15. The pressing table 15 is matched with the inlet 6. The lifting of the pressing table 15 in cooperation with the rotation of the dividing mesh plate 10 can initially crush the materials falling on the dividing mesh plate 10, so that the materials falling below are not too large, and then the grinding work will not be adversely affected by too large pieces of materials.
[0028] During the use of the utility model, materials are directly put into the feeding port 6 through the feeding hopper 16. At this time, the rotating motor 3 drives the centrifugal disc 18 and the connecting frame 7 to rotate through the rotating shaft 4, and then drives the workbench 2 and the dividing screen plate 10 arranged in the feeding port 6 to rotate. The hydraulic cylinder 13 controls the lifting of the extrusion table 15 through the hydraulic column 14. In this way, the materials can enter the feeding port 6 when the extrusion table 15 rises, fall on the dividing screen plate 10, and then be crushed between the descending extrusion table 15 and the rotating dividing screen plate 10, and then fall through the dividing screen plate 10. In this way, it can effectively prevent the falling materials from being too large and affecting the safe and stable progress of the ultrafine powder grinding work. Subsequently, after the falling materials fall on the centrifugal disc 18, they will be thrown to the edge of the bucket-shaped cavity 5 under the action of centrifugal force, and then the grinding work is completed under the combined action of the rotating workbench 2 and the base 1. Subsequently, the materials are separated from the base 1 to complete the discharging work.
[0029] Refer to Figures 4 - 6 , an ultrafine powder sieving machine, including a base 19. A plurality of universal wheels 32 are symmetrically arranged on the lower end surface of the base 19. The universal wheels 32 enable the base 19 to be conveniently moved, and then it is convenient for the staff to push the entire device to move. Two symmetrically arranged support seats 20 are provided on the upper end surface of the base 19. A material box 21 is provided on the upper end surface of the base 19. The material box 21 is located between the two support seats 20. A support frame 22 is fixedly connected to the side walls of one ends of the two support seats 20. A vibration motor 23 is provided on the side wall of the support frame 22 away from the two support seats 20. A vibration shaft 24 is provided on the vibration motor 23. The end of the vibration shaft 24 away from the vibration motor 23 is fixedly connected to a vibration frame 25. Two screening components are provided on the vibration frame 25;
[0030] The screening component includes a magnet groove 26 arranged on the vibration frame 25. A magnet disc 27 is fixedly connected to the inner wall of the magnet groove 26. A magnet block 28 is slidably connected in the magnet groove 26. The magnet block 28 and the magnet disc 27 attract each other. The magnet block 28 is fixedly connected to a screening mesh plate 29. In this way, by means of magnet adsorption, the screening mesh plate 29 can conveniently complete the vibration work and can be conveniently disassembled and assembled. In this way, when some of the screening mesh plates 29 are being cleaned, the cooperation of multiple screening mesh plates 29 can ensure that the screening work can continue without being affected, greatly ensuring the long-term stability of the screening work. Slide grooves 30 are provided on the side walls of the two support seats 20 close to each other. Slide bars 31 are slidably connected in the two slide grooves 30. The two slide bars 31 are respectively fixedly connected to the side walls of the two ends of the screening mesh plate 29. In this way, the screening mesh plate 29 can slide and vibrate more stably, and at the same time, it is convenient to pull and lift the screening mesh plate 29 by means of the slide bars 31, which is convenient for the staff to operate.
[0031] During the use of the utility model, the ultrafine powder product will fall onto the screening mesh plate 29. At this time, the vibration motor 23 can control the vibration of the vibration frame 25 by means of the vibration shaft 24, and then drive the screening mesh plate 29 to vibrate through the mutual attraction of the magnet disk 27 and the magnet block 28. In this way, the screening mesh plate 29 can complete the vibration screening work of the product. When the screening mesh plate 29 in operation needs to be cleaned due to blockage or other problems, the staff can take out another standby screening mesh plate 29, and by sliding the sliding strip 31 in the sliding groove 30, stably insert the screening mesh plate 29 between the two support seats 20, so that the magnet block 28 on this screening mesh plate 29 is inserted into the corresponding magnet groove 26 and adsorbed with the magnet disk 27. Then, the screening mesh plate 29 to be cleaned can be removed. The newly installed screening mesh plate 29 can ensure that the screening work will not be affected during this process. The product can complete the screening work through the new screening mesh plate 29 and then fall into the material box 21. Such an operation greatly ensures the long-term stability of the screening work and is very beneficial for the staff to use.

Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the utility model.
