[0022] Example: A tobacco foreign body sorting and removing device, such as Figure 1-Figure 3As shown, it includes a bottom plate 1, an outer shell 2, an inner shell 3, a motor 4, a cover plate 5, a partition 14 and a door panel 17. The outer shell 2 is mounted on the bottom plate 1 through a bracket. The outer shell 2 is a spherical shell as a whole. The inner shell 3 is rotatably mounted inside the outer shell 2. The inner shell 3 is a shell with multiple openings. The motor 4 is mounted on the bottom plate 1. The output shaft of the motor 4 passes through the outer shell 2 and is connected to the inner shell 3. The tops of the outer shell 2 and the inner shell 3 are both provided with a feed opening. The cover plate 5 is provided on the discharge port of the outer shell 2, and a plurality of partitions 14 are evenly fixedly installed on the inner wall of the inner shell 3 in the circumferential direction. The front side wall of the outer shell 2 is provided with an opening, and the outer shell 2 is provided with a door panel 17 through the opening. The door panel 17 is a curved plate that fits tightly against the curved surface of the outer shell 2. The motor 4 drives the inner shell 3 to rotate in the outer shell 2, so that the tobacco raw material placed in the inner shell 3 can be filtered out of foreign matter in the tobacco raw material to the inner wall of the outer shell 2 under the action of centrifugal force.

[0023] like Figure 3 and Figure 4 As shown, sealing rubber pads are provided at the discharge port of the shell 2 and the edge of the lower side of the cover plate 5. The two sealing rubber pads fit together to improve the air tightness inside the shell 2; it also includes a limiting block 6 and a clamping block 7. The limiting blocks 6 are symmetrically provided at the top of the shell 2 near the discharge port, and the clamping blocks 7 are provided on the left and right sides of the bottom of the cover plate 5. The limiting blocks 6 and the corresponding clamping blocks 7 are adapted and snapped to each other, so that the cover plate 5 can be stably placed on the top of the shell 2.

[0024] like Figure 2 and Figure 3 As shown, it also includes an air pump Ⅰ8 and an air inlet pipe Ⅰ9. The air pump Ⅰ8 is installed on the top of the cover plate 5, and the air outlet of the air pump Ⅰ8 is connected to the bottom of the cover plate 5 through the air inlet pipe Ⅰ9. The air inlet pipe Ⅰ9 runs through the entire cover plate 5 and extends into the inner shell 3; it also includes an air outlet pipe 10 and a filter 11. The cover plate 5 is connected with the air outlet pipe 10, and the filter 11 is installed on the top of the air outlet pipe 10. The air outlet pipe 10 is used to discharge the waste gas generated during the sorting of foreign matter in tobacco, and the waste gas is safely discharged after being filtered by the filter 11.

[0025] like Figure 2 As shown, it also includes an arc-shaped magnetic plate 12, which is fixedly mounted on the inner wall of the outer shell 2, and the arc-shaped magnetic plate 12 does not cover the position of the front side of the outer shell 2 corresponding to the door panel 17; a scraper 13 is provided on the arc-shaped magnetic plate 12, and an arc-shaped slide groove is opened on the side wall of the outer shell 2, and the slide groove does not extend to the front side of the outer shell 2. The outer shell 2 is slidably mounted with a scraper 13 through the slide groove, and the lower end of the scraper 13 is attached to the inner wall of the arc-shaped magnetic plate 12.

[0026] like Figure 3 As shown, it also includes an air pump II 15 and an air intake pipe II 16. The air pump II 15 is installed at the bottom of the outer shell 2. The air outlet of the air pump II 15 passes through the outer shell 2 through the air intake pipe II 16 and is connected to the bottom of the inner shell 3. The air pump II 15 is used to assist and cooperate with the air pump I8 to perform airflow sorting.

[0027] When using the present device to sort foreign matter in tobacco raw materials, the operator first lifts up the cover plate 5 by hand and puts the tobacco raw materials to be sorted into the inner shell 3. When the tobacco raw materials are put out, the cover plate 5 can be stably put back on the outer shell 2 after the limit block 6 and the card block 7 are aligned. Then the motor 4 is activated. The motor 4 drives the inner shell 3 to rotate in the outer shell 2 through the coupling, so that the rotating inner shell 3 can drive the tobacco raw materials inside it to roll through the partition 14. When the inner shell 3 rotates at high speed, foreign matter such as metal mixed in the tobacco raw materials inside it will be thrown to the outside of the inner shell 3 under the action of centrifugal force. In this process, the air pump I8 and the air pump II15 are activated at the same time. The air pump I8 injects gas downward into the inner shell 3 through the air inlet pipe I9, and the air pump II15 injects gas upward into the inner shell 3 through the air inlet pipe II16. At this time, the two air flows injected into the inner shell 3 from the upper and lower directions will collide, so that the collided air flows will enter The tumbling rate of the tobacco raw materials in the inner shell 3 is further accelerated, and the high-speed rotation of the inner shell 3 is combined with the various foreign matter mixed in the tobacco raw materials to be further separated. At the same time, the separated small metal foreign matter will be attracted by the arc-shaped magnetic plate 12, pass through the openings on the inner shell 3 and be adsorbed on the inner wall of the arc-shaped magnetic plate 12, while other non-metallic foreign matter will fall on the bottom of the outer shell 2 after passing through the openings on the inner shell 3. When the tobacco raw materials are sorted for foreign matter in the inner shell 3, the waste gas generated will enter the outlet pipe 10 and be safely discharged into the outside air after being filtered by the filter 11. After a batch of tobacco raw materials is sorted, the door panel 17 is opened and the scraper 13 is slid along the arc-shaped slide groove on the outer shell 2. The scraper 13 can scrape the metal foreign matter adsorbed on the inner wall of the arc-shaped magnetic plate 12 to the front opening of the outer shell 2 for subsequent collection and recycling. Finally, the cover plate 5 is opened to pour the sorted tobacco out of the outer shell 2 for centralized collection.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
