Specific embodiments

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model.

[0028] Embodiment 1

[0029] Refer to Figure 1 , 2, 4 and 6 are the first embodiment of the present utility model. This embodiment provides a circular vibrating sieve for ultra-fine bismuth powder, including a screening box 1. A number of groups of elastic mechanisms 2 are symmetrically arranged at the bottom of the surface of the screening box 1. One side of the front of the screening box 1 is fixedly installed with a circular vibration mechanism 3. The bottom of the elastic mechanism 2 is fixedly provided with a bottom plate 4. The edge of the top surface of the bottom plate 4 is fixedly installed with a high-pressure air pump 5. The back of the screening box 1 is fixedly installed with a translation mechanism 6. The surface of the translation mechanism 6 is threadedly connected with a high-pressure spray pipe 7; the translation mechanism 6 includes an A servo motor 601 fixedly installed on the back of the screening box 1, and the output end of the A servo motor 601 is fixedly provided with a threaded lead screw 602.

[0030] Specifically, the elastic mechanism 2 includes A fixing blocks 201 symmetrically arranged at the bottom of the surface of the screening box 1. The bottom of the A fixing blocks 201 is fixedly provided with vibration springs 202. The bottom of the vibration springs 202 is fixedly provided with B fixing blocks 203. The circular vibration mechanism 3 includes a B servo motor 301 fixedly installed on one side of the front of the screening box 1. The output end of the B servo motor 301 is fixedly provided with an eccentric block 302. The output end of the high-pressure air pump 5 is communicated with an air delivery pipe 11. One end of the air delivery pipe 11 is connected and communicated with the high-pressure spray pipe 7. A number of high-pressure nozzles 12 are equidistantly communicated along the axial direction on the top surface of the high-pressure spray pipe 7. One side of the screening box 1 is fixedly installed with a discharge inclined plate 13. Both sides of the inner wall of the screening box 1 are provided with sliding grooves, and both ends of the high-pressure spray pipe 7 are slidably connected inside the sliding grooves.

[0031] Furthermore, when screening ultra-fine bismuth powder, the material is put into the screening box 1, and the external power supply is connected. The B servo motor 301 drives the eccentric block 302 to rotate, driving the screening box 1 to vibrate. The vibration springs 202 are compressed and deformed accordingly to screen the bismuth powder. After the circular vibrating sieve is used, the A servo motor 601 is connected to the external power supply to drive the threaded lead screw 602 to rotate, so that the high-pressure spray pipe 7 translates on the bottom surface of the sieve plate 8. The high-pressure air pump 5 delivers high-pressure gas to the high-pressure spray pipe 7 through the air delivery pipe 11, and then blows out the gas through the high-pressure nozzles 12 to blow away the bismuth powder blocked in the mesh holes of the sieve plate 8, avoiding the blockage of the sieve plate 8 and affecting the screening of ultra-fine bismuth powder.

[0032] Embodiment 2

[0033] Refer to Figure 1 , 2 And 3 are the second embodiment of the present utility model. This embodiment is based on the previous embodiment. A sieve plate 8 is slidably connected inside the screening box 1. Both sides of the sieve plate 8 are fixedly installed with limiting mechanisms 9; the limiting mechanisms 9 include limiting springs 901 fixedly installed on both sides of the sieve plate 8. One end of the limiting springs 901 is fixedly provided with sliding blocks 902. One side of the sliding blocks 902 is fixedly provided with limiting blocks 903.

[0034] Specifically, limiting grooves are provided on both sides of the sieve plate 8, and the sliding block 902 is slidably connected to the inside of the limiting groove. Clamping blocks 10 for limiting the limiting block 903 are fixedly installed on both sides of the screening box 1.

[0035] Furthermore, when installing the sieve plate 8, insert the sieve plate 8 into the screening box 1, move the limiting block 903 to compress the limiting spring 901 by the sliding block 902. When the sieve plate 8 is installed in place, release the limiting block 903, and the limiting spring 901 rebounds to insert the limiting block 903 into the clamping block 10, enabling the sieve plate 8 to be quickly fixed. When disassembling the sieve plate 8, only need to remove the limiting block 903 from the clamping block 10 for disassembly, which is convenient for personnel to replace and maintain the sieve plate 8.

[0036] Working principle: When installing the sieve plate 8, insert the sieve plate 8 into the screening box 1, move the limiting block 903 to compress the limiting spring 901 by the sliding block 902. When the sieve plate 8 is installed in place, release the limiting block 903, and the limiting spring 901 rebounds to insert the limiting block 903 into the clamping block 10, enabling the sieve plate 8 to be quickly fixed. When disassembling the sieve plate 8, only need to remove the limiting block 903 from the clamping block 10 for disassembly, which is convenient for personnel to replace and maintain the sieve plate 8. When screening ultra-fine bismuth powder, put the material into the screening box 1, connect to the external power supply, the B servo motor 301 drives the eccentric block 302 to rotate, driving the screening box 1 to vibrate. The vibration spring 202 is compressed and deforms accordingly to screen the bismuth powder. After the circular vibrating screen is used, connect the A servo motor 601 to the external power supply to drive the threaded screw 602 to rotate, causing the high-pressure nozzle 7 to translate on the bottom surface of the sieve plate 8. The high-pressure air pump 5 transports high-pressure gas to the high-pressure nozzle 7 through the air delivery pipe 11, and then blows out the gas through the high-pressure nozzle 12 to blow away the bismuth powder blocked in the mesh holes of the sieve plate 8, preventing the sieve plate 8 from being blocked and affecting the screening of ultra-fine bismuth powder.
