[0033] The filter cylinder 404 is sleeved on the outer side of the fixed pipe 401 and fixedly connected with the outer tooth ring 403, and the part of the filter cylinder 404 that exceeds the fixed pipe 401 is provided with a filter hole, which is used for realizing the filtering operation of the ore pulp;

[0034] The reduction motor 410 is fixedly installed on the outer side of the top of the fixed pipe 401 through the connecting frame 411, the first gear 412 is fixedly connected to the output end of the reduction motor 410 and meshes with the outer tooth ring 403, and the rotation of the filter cylinder 404 is realized by the operation of the reduction motor 410;

[0035] The scraping and conveying unit comprises a second annular groove 405, a rotating disc 406, an annular inner tooth groove 407, an L-shaped connecting arm 408, a spiral feeding piece 409, a connecting shaft 413 and a second gear 414.

[0036] The second annular groove 405 is arranged on the outer side of the end of the filter cylinder 404 away from the outer tooth ring 403, and the rotating disc 406 is rotationally connected to the inner side of the second annular groove 405.

[0037] The annular inner tooth groove 407 is formed on the end face of the rotating disc 406 close to the outer tooth ring 403, the connecting shaft 413 is fixed to one end of the first gear 412, the second gear 414 is fixed to one end of the connecting shaft 413 and distributed on the inner side of the annular inner tooth groove 407, and the second gear 414 meshes with the annular inner tooth groove 407.

[0038] The L-shaped connecting arm 408 is fixed to the end of the rotating disc 406 away from the outer tooth ring 403, the vertical part of the L-shaped connecting arm 408 is fixedly connected with the spiral feeding piece 409, the spiral feeding piece 409 extends to the inner side of the filter cylinder 404 and is attached to the inner wall of the filter cylinder 404, and the ore slag in the filter cylinder 404 is scraped and conveyed to the discharge port of the filter cylinder 404 by the rotation of the rotating disc 406, the L-shaped connecting arm 408 and the spiral feeding piece 409.

[0039] In the embodiment, it should be noted that the flotation machine body 1 has the same operation principle as the common flotation machine in the market, and therefore the internal structure of the flotation machine body 1 is not described here.

[0040] When the ore slag needs to be discharged, the electric valve 3 and the reduction motor 410 are started at the same time, the electric valve 3 is opened, the ore pulp in the flotation machine body 1 flows through the discharge port 2, the electric valve 3 and the fixed pipe 401 in sequence and enters the inside of the filter cylinder 404 (it should be noted that the filter cylinder 404 has a relatively long length, so that the ore pulp will not impact the discharge port of the filter cylinder 404).

[0041] The ore pulp entering the inside of the filter cylinder 404 will flow out through the filter holes on the filter cylinder 404, and the ore dregs in the ore pulp are intercepted inside the filter cylinder 404 (it is to be noted that a corresponding flow guide groove is arranged at the lower region of the filter cylinder 404 to collect and transport the outflowing ore pulp to the next process);

[0042] At the same time, the deceleration motor 410 drives the first gear 412 and the second gear 414 to rotate synchronously, the first gear 412 drives the outer tooth ring 403 and the filter cylinder 404 to rotate, compared with fixed different filter cylinder structures, the filter cylinder 404 can keep good filtering effect;

[0043] The second gear 414 drives the rotating disc 406, the L-shaped connecting arm 408 and the spiral feeding piece 409 to rotate as a whole, and the rotating direction of the spiral feeding piece 409 is opposite to that of the filter cylinder 404, the rotating spiral feeding piece 409 can scrape the inner wall of the filter cylinder 404 and push the filtered ore dregs to the direction of the discharge port of the filter cylinder 404, which not only realizes efficient separation of the ore dregs and the ore pulp, but also effectively avoids the filter cylinder 404 from being blocked, thereby ensuring long-time stable filtering effect of the ore dregs discharging and filtering assembly 4.

[0044] Please pay attention to Figs. 1-4 The filter cylinder 404 is not provided with filter holes at the position close to the fixed pipe 401 and the second annular groove 405.

[0045] In the embodiment, the ore pulp and the ore dregs will not contact the rotating region of the outer tooth ring 403 and the rotating disc 406 through the structure, thereby ensuring stable rotation of the outer tooth ring 403 and the rotating disc 406.

[0046] It is to be further noted that the first gear 412, the connecting shaft 413 and the second gear 414 are distributed above the filter cylinder 404, the filter cylinder 404 keeps low-speed rotation, and the ore pulp will not splash upward, thereby further avoiding the ore pulp from contacting the first gear 412, the connecting shaft 413 and the second gear 414, so that the first gear 412 and the second gear 414 keep good transmission state.

[0047] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
