[0038] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0039] Embodiment 1

[0040] This embodiment provides a technical solution: an environmentally friendly and emission-reducing clean feed ultrafine grinding device, such as Figure 1-Figure 8As shown, it includes a processing cylinder 1, a crushing cylinder group 2, a suction component 4 and a driving component 5.

[0041] In the specific implementation, such as Figure 3-Figure 6 As shown, the grinding cylinder group 2 is evenly arranged in an annular shape in the processing cylinder 1, and the grinding cylinder group 2 includes an outer semi-ring cylinder 201 with a discharge hole 6, an inner semi-ring cylinder 202, a mounting gasket 203 and a mounting bent rod 204. The outer semi-ring cylinder 201 and the inner semi-ring cylinder 202 are relatively cylindrically arranged. The aperture size of the discharge hole 6 on the outer semi-ring cylinder 201 should be determined according to the set particle size. Both ends of the outer semi-ring cylinder 201 and the inner semi-ring cylinder 202 are provided with connecting pieces for connection. When in use, the connecting pieces on both sides of the outer semi-ring cylinder 201 are attached to the connecting pieces on both sides of the inner semi-ring cylinder 202 and are fixed by the connecting piece The fixed connection can make the outer semi-annular cylinder 201 and the inner semi-annular cylinder 202 be used as a whole, the mounting gasket 203 is fixedly installed on the bottom of the outer semi-annular cylinder 201 and the inner semi-annular cylinder 202, the mounting bent rod 204 is installed between the mounting gasket 203 and the inner wall of the processing cylinder 1, the cross-sectional shape of the mounting bent rod 204 is a triangle, and the triangles of the triangle are arranged with one corner at the top and two corners at the bottom. By installing the bent rod 204, the crushing cylinder group 2 can be stably arranged and its two side surfaces can play a role in guiding the particles falling from above, which can facilitate the situation where a large number of particles are retained on the mounting bent rod 204.

[0042] In the specific implementation, such as Figure 5-Figure 6 As shown, a crushing assembly 3 is arranged in the crushing cylinder group 2, and the crushing assembly 3 includes a motor 301, a brake rod 302 and a plurality of crushing blades 303. The inner walls of the outer semi-ring cylinder 201 and the inner semi-ring cylinder 202 are welded with a mounting semi-ring piece 10 and a plurality of semi-ring spacers 11 with sieve holes 12 in sequence from bottom to top. The size of the sieve holes 12 on the semi-ring spacers 11 should be reduced from top to bottom to ensure a stable falling process and avoid blockage. In addition, the semi-ring spacers 11 can separate a plurality of crushing chambers between each other to achieve crushing effects to different degrees. The motor 301 is fixedly mounted on the bottom of the mounting semi-ring piece 10, and a mounting hole is provided at the center position of the semi-ring spacer 11. The brake rod 302 is mounted on the output shaft of the motor 301 and rotatably mounted in the mounting hole. The crushing blades 303 are evenly mounted on the brake rod 302, and the crushing blades 303 are evenly arranged in a plurality of crushing chambers to ensure that each crushing chamber has a good crushing effect and can produce a composite feed particle output.

[0043] In the specific implementation, such as Figure 3 and Figure 8As shown, the attraction component 4 is used to absorb the feed particles in the crushing cylinder group 2. The attraction component 4 is arranged between the crushing cylinder group 2 and the inner wall of the processing cylinder 1. The attraction component 4 includes a mounting plate 401 and a corona wire 402. The corona wire 402 is installed on one side of the mounting plate 401 and is arranged corresponding to the external semi-annular cylinder 201. The attraction effect generated by the corona wire 402 can attract and move feed particles of qualified size toward the corona wire 402, and then the feed particles can pass through the discharge hole 6 on the external semi-annular cylinder 201 and move out and be attracted to the corona wire 402. It should be noted that an independent power supply needs to be set on the mounting plate 401 to power the electrical appliances on the mounting plate 401.

[0044] In the specific implementation, such as Figure 3 and Figure 7 As shown, the driving assembly 5 is used to control the movement of the suction assembly 4. The driving assembly 5 is arranged on the top of the processing cylinder 1. The driving assembly 5 includes a motor 501, a brake gear 502 and a driven gear ring 503. A built-in ring 7 is welded on the top of the inner wall of the processing cylinder 1, and a mounting ring 8 is welded on the bottom of the inner side of the built-in ring 7. The driven gear ring 503 is rotatably mounted on the outside of the mounting ring 8. A pad 9 is installed on the outside of the processing cylinder 1. The motor 501 is fixedly installed on the pad 9. The brake gear 502 is installed on the output shaft of the motor 501. A through hole is opened on one side of the processing cylinder 1. One end of the brake gear 502 passes through the through hole and is connected to the driven gear ring 503 are meshed, and the mounting plate 401 is fixedly installed at the bottom of the driven gear ring 503. The motor 501 can drive the brake gear 502 to rotate, so the brake gear 502 can drive the driven gear ring to rotate, and under the drive of the driven gear ring, the attraction component 4 can be controlled to move continuously in a circular trajectory, so that the qualified feed particles in each crushing cylinder group 2 can be driven to move out through the attraction component 4, and because the attraction component 4 is in a moving state, most of the attracted and moved feed particles will fall directly downwards after moving out of the crushing cylinder group 2 due to the loss of the attraction effect, thereby facilitating the collection of a large amount of feed particles.

[0045] In the specific implementation, such as Figure 1 As shown, a top plate 18 is fixedly installed on the top of the processing cylinder 1, and a card-releasing hole corresponding to the top of the external semi-annular cylinder 201 and the internal semi-annular cylinder 202 is opened on the top plate 18. A feed pipe 19 is arranged on the top of the top plate 18, and a diverter pipe 20 is installed between the bottom edge of the feed pipe 19 and the card-releasing hole. A discharge pipe 21 is arranged at the bottom of the processing cylinder 1, and the feed pipe 19, the diverter pipe 20 and the discharge pipe 21 can facilitate the input and discharge of materials.

[0046] During processing, the grains are put into the feed pipe 19, and under the action of gravity, they can evenly enter each crushing barrel group 2 through each diversion pipe 20, and the crushing assembly 3 is started in the crushing barrel. The motor 301 can drive the brake rod 302 and each crushing cutter head 303 to rotate, and the crushing cutter head 303 can crush the grains entering the crushing barrel group 2. Since a plurality of crushing chambers are arranged in the crushing barrel group 2 and the size of the sieve holes 12 on the semi-ring spacer 11 at the bottom of each crushing chamber should decrease from top to bottom, the semi-ring spacer 11 can prevent the grains from falling directly to ensure sufficient crushing time, and the feed particles retained in each crushing chamber have different specifications, so that the crushing can have a strong sense of hierarchy and reduce blockage. After the crushing starts Start the driving component 5 and the corona wire 402, the motor 501 can drive the brake gear 502 to rotate, so the brake gear 502 can drive the driven gear ring to rotate, and under the drive of the driven gear ring, the suction component 4 can be controlled to move continuously in a circular trajectory. During movement, the feed particles in each crushing cylinder group 2 can be attracted and moved under the suction action of the corona wire 402, so qualified feed particles with a particle size smaller than the size of the discharge hole 6 can pass through the discharge hole 6, and then continue to move toward the position of the corona wire 402. Moreover, since the suction component 4 is in a moving state, most of the attracted and moved feed particles will directly fall downwards after moving out of the crushing cylinder group 2 due to the loss of suction effect and be discharged through the discharge pipe 21 at the bottom.

[0047] Embodiment 2

[0048] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, in order to better realize the present invention, the following configuration is particularly adopted: In this embodiment, in order to prevent qualified feed particles and unqualified feed particles from accumulating at the bottom of the grinding cylinder group 2, a reflux component 13 is added that can push the accumulated particles at the bottom upward.

[0049] In the specific implementation, such as Figure 4 and Figure 8As shown, a reflux assembly 13 for controlling the upward movement of feed particles at the bottom is provided at the bottom of the outer side of the built-in semi-annular cylinder 202. The reflux assembly 13 includes an arc-shaped plate frame 1301, a push block 1302 and a control cylinder 1303. The arc-shaped plate frame 1301 is fixedly installed at the outer bottom of the built-in semi-annular cylinder 202. A receiving cavity is provided in the arc-shaped plate frame 1301. The control cylinder 1303 is fixedly installed at the top of the arc-shaped plate frame 1301. The push block 1302 is clamped in the receiving cavity and installed at the output end of the control cylinder 1303. A discharge port 14 and a reflux port 15 are provided at the bottom of the built-in semi-annular cylinder 202. The reflux port 15 is located at the discharge port 1 4, the bottom of the reflux port 15 is at the same level as the top of the semi-ring plate 10 to ensure that the feed particles accumulated at the bottom can also be transported out. The reflux port 15 needs to be set at least on the side of the second to last grinding chamber and above the middle position of the grinding chamber, so as to ensure that the refluxed particles have enough space to move to increase the probability of being sucked out, and at the same time, it can better prevent the particles in the grinding chamber from moving out of the reflux port 15. The pushing block 1302 is attached to the outside of the discharge port 14 and the reflux port 15. The length of the pushing block 1302 is greater than the distance between the discharge port 14 and the reflux port 15 to prevent the leakage of feed particles in the grinding cylinder group 2.

[0050] In the specific implementation, such as Fig. 9 As shown, a limiting slope 16 is provided on the top of the push block 1302, and the limiting slope 16 can ensure that the feed particles can move back to the grinding cylinder group 2 along the limiting slope 16 under the action of gravity after moving to the reflux port 15.

[0051] During the crushing process, the reflux component 13 is started, and the control cylinder 1303 can drive the pushing block 1302 to move up and down continuously. During the movement, the extension depth of the control cylinder 1303 can be adjusted so as not to be too fast to ensure a smooth process. When the pushing block 1302 moves to the lowest part, the pushing block 1302 is located at the bottom of the discharge port 14. Therefore, the feed particles accumulated at the bottom of the lowest crushing chamber can pass through the discharge port 14 into the arc plate frame 1301 under the action of gravity. Then, the control cylinder 1303 can pull the pushing block 1302 upward, and at the same time, the bottom of the pushing block 1302 can block the discharge port 14. After the feed particles recovered from the top move to the reflux port 15 position, they can move back to the crushing barrel group 2 along the limiting slope 16 under the action of gravity. Therefore, the refluxed feed particles can be crushed again, and qualified feed particles are very likely to be attracted and removed, thereby ensuring a high product qualification rate.

[0052] Embodiment 3

[0053] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Figure 3 , Figure 7 , Fig.10and Fig.11 As shown, in order to better realize the present invention, the following setting is particularly adopted: in this embodiment, in order to prevent the corona wire 402 from being adsorbed with more feed particles and causing the attraction effect to deteriorate, a cleaning component 17 is added that can automatically clean the surface of the corona wire 402 without stopping the machine.

[0054] In the specific implementation, such as Fig.10 and Fig.11 As shown, a cleaning assembly 17 for scraping off feed particles is provided on the mounting plate 401, and the cleaning assembly 17 includes an upper scraper 1701, a lower scraper 1702, a linkage rod 1703, a control frame 1704, a control sheet 1705 and a hydraulic cylinder 1706. The upper scraper 1701 and the lower scraper 1702 are both sleeved on the outside of the corona wire 402, and the linkage rod 1703 is installed between the upper scraper 1701 and the lower scraper 1702, and both sides are provided with a to ensure that the upper scraper 1701 and the lower scraper 1702 have a good connection stability. The upper scraper 1701 can clean the upper part of the corona wire 402, and the lower scraper 1702 can clean the lower part of the corona wire 402, thereby ensuring a good cleaning effect. Guide grooves are provided on both sides of the mounting plate 401, the control frame 1704 is installed on one side of the connecting rod 1703 and is clamped in the guide groove, the control plate 1705 is installed on the rear side of the control frame 1704 and is located on the rear side of the mounting plate 401, the hydraulic cylinder 1706 is fixedly installed on the rear side of the mounting plate 401, and the control plate 1705 is installed on the output end of the hydraulic cylinder 1706.

[0055] During cleaning, the hydraulic cylinder 1706 is started by timing control. The hydraulic cylinder 1706 can drive the control plate 1705 to move up and down, so the control plate 1705 can drive the control frame 1704 and the connecting rod 1703 to move up and down along the guide groove. Driven by the connecting rod 1703, the upper scraper 1701 and the lower scraper 1702 can move along the surface of the corona wire 402, so that the feed particles attached to the surface of the corona wire 402 can be scraped off, thereby ensuring that the corona wire 402 can be used normally.
