[0019] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-6The present invention provides a technical solution: a composite powder classifier, which includes: a first filter bin 6, an air flow bin 17 and a second filter bin 16. The upper end of the first filter bin 6 is fixedly connected with a storage bin 2. The material can be poured into the storage bin 2 before use. The lower end of the first filter bin 6 is rotatably connected to the gear ring 10, and the other side of the gear ring 10 is rotatably connected to the fixed ring 12. The impurities in the first filter bin 6 can be cleaned by rotating the gear ring 10. The lower side of the fixed ring 12 is fixedly connected to the air flow bin 17, and the lower side of the air flow bin 17 is fixedly connected to the second filter bin 16. The lower end of the second filter bin 16 is fixedly connected to the discharge bin 21. After the material passes through the second filter bin 16, it can be screened again, so that the two sizes of materials are separated and the storage bin 2 is used. The upper end of the bin 2 is fixedly connected to a motor 1, and the output end of the motor 1 is fixedly connected to a rotating rod 3, which can be driven to rotate by the motor 1. The other end of the rotating rod 3 is fixedly connected to the upper end of the vertebral plate 7, and a number of stirring plates 5 are fixedly connected to the surface of the rotating rod 3. When the rotating rod 3 rotates, the stirring plates 5 rotate accordingly. The inner wall of the storage bin 2 is fixedly connected to a number of fixed plates 4, and the several fixed plates 4 are evenly divided into upper and lower layers. The horizontal heights of the several stirring plates 5 are between the horizontal heights of the upper fixed plates 4 and the lower fixed plates 4. At this time, when the stirring plate 5 rotates, it will continuously pass through the fixed plates 4, and the end of the several fixed plates 4 away from the storage bin 2 does not contact the rotating rod 3, so that the material can be stirred and broken up to avoid agglomeration.

[0021] Pour the material into the storage bin 2 and start the motor 1. At this time, the stirring plate 5 starts to rotate, and the stirring plate 5 continuously passes through the fixed plate 4, so that the agglomerated parts of the material will be squeezed and broken up by the stirring plate 5 and the fixed plate 4, thereby improving the overall utilization rate.

[0022] The tip of the vertebral plate 7 is upward, and the lower end of the vertebral plate 7 is fixedly connected to the screen plate 9. When the material passes through the storage bin 2 and enters through the through hole at the upper end of the first filter bin 6, the material will first contact the upper end of the vertebral plate 7, and then slide along the vertebral plate 7. The surfaces of the vertebral plate 7 and the screen plate 9 are both provided with filter holes 8. The side of the screen plate 9 is fixedly connected to the inner ring surface of the fixing ring 12. The material can be filtered through the filter holes 8, so that the coarse powder is separated. The upper and lower sides of the gear ring 10 are fixedly connected with protrusions, and the protrusions on both sides are respectively inserted into the first filter bin 6 and the fixing ring 12, so that the gear ring 1 0 can rotate normally, and a discharge port 13 is provided on the side of the fixed ring 12, which is convenient for cleaning the coarse powder. A number of scrapers 11 are evenly and fixedly connected to the inner ring surface of the gear ring 10. The other end of the scraper 11 is in contact with the vertebral plate 7, and the lower side of the scraper 11 is in contact with the upper surface of the sieve plate 9. When the gear ring 10 rotates, the scraper 11 will rotate accordingly, and the coarse powder can be scraped by the scraper 11. The extension line of the scraper 11 does not intersect with the center of the sieve plate 9 to ensure that the scraper 11 is in an inclined state. At this time, when the scraper 11 rotates, the coarse powder can move along its surface and finally be discharged from the discharge port 13.

[0023] When the material enters the first filter bin 6, it will slide along the surface of the vertebral plate 7. When passing through the filter hole 8, the medium powder and fine powder will pass through the filter hole 8, while the coarse powder will continue to slide to the surface of the sieve plate 9. At this time, when the gear ring 10 rotates, the scraper 11 can scrape the coarse powder, causing it to move along the scraper 11 and be discharged from the discharge port 13.

[0024] The outer side of the gear ring 10 is meshed with the gear 25, and the gear 25 is fixedly connected to the output end of the motor 2 24. When the motor 24 rotates, the gear 25 rotates, thereby driving the gear ring 10 to rotate. The motor 24 is fixedly connected to the outer surface of the airflow chamber 17.

[0025] The air flow bin 17 is fixedly connected to the air guide pipe 23, and the other end of the air guide pipe 23 is fixedly connected to the output end of the air pump 22. After the air pump 22 is started, the air pump 22 will rush a large amount of high-speed air into the air flow bin 17 through the air guide pipe 23. The interior of the air flow bin 17 and the air guide pipe 23 are interconnected, and the inner wall of the air guide pipe 23 is tangent to the inner wall of the air flow bin 17, so that the air flow can rotate along the inner wall of the air flow bin 17 to form a cyclone. The inner wall of the air flow bin 17 is fixedly connected to the fixing frame 15, and the fixing frame 15 is fixedly connected to the conical member 14, and the conical member 14 does not contact the air flow bin 17, so that the material can enter the air flow bin 17, and the tip of the conical member 14 is upward, and the tip of the conical member 14 is fixedly connected to the inner wall of the upper end of the vertebral plate 7. At this time, the position of the conical member 14 is fixed, and the surface of the conical member 14 does not contact the inner wall of the vertebral plate 7, so that the medium powder and fine powder can slide along the surface of the conical member 14.

[0026] When the material enters through the filter hole 8, it can slide along the surface of the cone 14 and then enter the edge of the air flow bin 17. At this time, the air pump 22 is started, and a cyclone is generated in the air flow bin 17. Under the influence of gravity and wind, the material begins to rotate and fall along the inner wall of the second vertebral plate 18. At this time, under the action of the sieve hole 19, the fine powder will pass through the sieve hole 19, while the medium powder will continue to move along the second vertebral plate 18.

[0027] The tip of the vertebral plate 18 is downward-pointing, and a plurality of sieve holes 19 are evenly opened on the surface of the vertebral plate 18. The upper side of the vertebral plate 18 is fixedly connected to the inner wall of the discharge bin 21 to fix the vertebral plate 18. The lower end of the vertebral plate 18 is fixedly connected to the guide pipe 20. At this time, the medium powder can be discharged along the guide pipe 20. The other end of the guide pipe 20 passes straight through the discharge bin 21. The diameter of several filter holes 8 is larger than the diameter of the sieve hole 19, and the fine powder can be discharged through the discharge bin 21.

[0028] When the fine powder is separated from the medium powder, the two can be discharged separately through the gap of the discharge bin 21 and the guide pipe 20.

[0029] During actual use, start motor 1, motor 2 24 and air pump 22, and add material into storage bin 2 at this time. When passing through storage bin 2, the agglomerated parts in the material will be broken up. When passing through the first filter bin 6, the coarse powder will be filtered out by vertebral plate 1 7 and stored on the surface of sieve plate 9. Under the action of scraper 11, the coarse powder is discharged from discharge port 13. When the remaining material enters the edge of air flow bin 17 along conical part 14, it will rotate along the inner wall of vertebral plate 2 18 under the action of wind force, thereby separating medium powder from fine powder. The medium powder is discharged from guide pipe 20, and the fine powder is discharged from discharge bin 21, thereby realizing screening of material cement, and the different grades of parts can be screened separately as a whole to avoid materials of different sizes falling together, thereby improving product quality.
