[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, the present invention provides a centrifugal concentrator for ore dressing, comprising a buffer mechanism 1, the buffer mechanism 1 is arranged inside a centrifugal mechanism 2, a rotating mechanism 3 is arranged inside the centrifugal mechanism 2, the centrifugal mechanism 2 is arranged inside a main mechanism 4, and the buffer mechanism 1 is located above the rotating mechanism 3;

[0031] The buffer mechanism 1 includes a baffle 101, a slanted groove 102 and a sealing groove 112 are provided at the bottom of the baffle 101, an slanted plate 103 is slidably connected inside the slanted groove 102, a connecting plate 104 is fixedly connected to the bottom of the slanted plate 103, a first slide groove 105 is provided at the top of the connecting plate 104, a first limiting groove 106 is provided on the inner wall of the first slide groove 105, an anti-collision pad 107 is fixedly connected to the bottom of the connecting plate 104, a first slide groove 105 is slidably connected inside the first slide groove 108, first limiting blocks 109 are slidably connected on both sides of the first slide groove 108, a piston rod 110 is fixedly connected to the top of the first slide groove 108, and a first spring 111 is fixedly connected to the top of the piston rod 110.

[0032] The top of the piston rod 110 passes through the bottom of the baffle 101 and extends to the inside of the sealing groove 112. The top of the piston rod 110 is elastically connected to the inner wall of the sealing groove 112 through the first spring 111. The first limit block 109 is slidingly connected to the first limit groove 106. There are six baffles 101.

[0033] The above scheme is adopted: by setting the cooperation of structures such as the baffle 101 and the connecting plate 104, it is convenient to discharge the tailings. When the rotation speed of the drum 204 reaches the discharge speed, the device completes the selection and stratification through centrifugal force. At this time, the top of the second slider 303 and the bottom of the anti-collision pad 107 are completely released. At this time, the baffle 101 will rotate downward under the action of gravity and centrifugal force, driving the anti-collision pad 107 to re-abut against the side of the second slider 303, so that the tailings discharge chute 207 channel is opened. At this time, the particles with smaller density located at the center of the drum 204 will be discharged from the tailings discharge port 403 through the tailings discharge chute 207 with the water flow. In this process, the baffle 101 will move forward under the pressure of the water flow and the impact of the particles. The second slider 303 is rotated in the direction close to the second slider 303, so that the baffle 101 moves in the direction close to the connecting plate 104. At this time, the first slider 108 slides with the first slide groove 105, and the inclined plate 103 slides with the inclined groove 102. At the same time, the piston rod 110 squeezes the gas inside the sealing groove 112 and the first spring 111. The impact force is buffered by the air pressure and the elastic force of the first spring 111, and the baffle 101 is supported to prevent the impact from causing wear to the second slider 303. At the same time, the baffle 101 can shield the second limit groove 306 and the second limit block 307 on the second slider 303 to prevent the remaining particles from affecting the subsequent resetting of the second slider 303, resulting in the device not being able to work normally.

[0034] like Figures 3 to 8As shown, the centrifugal mechanism 2 includes a motor 201, the top of the output end of the motor 201 is rotatably connected to a first gear 202, the side of the first gear 202 is meshed with a second gear 203, the top of the second gear 203 is fixedly connected to a rotating drum 204, a concentrate discharge hole 205 is provided at the bottom of the rotating drum 204, an electronic valve 206 is arranged inside the concentrate discharge hole 205, a tailings discharge chute 207 is provided at the bottom of the rotating drum 204, a rotating groove 208 is provided on the inner wall of the tailings discharge chute 207, and six second chute grooves 209 are evenly arranged on the inner wall of the rotating groove 208.

[0036] The rotating mechanism 3 includes a driven housing 301, and six third sliding grooves 302 are evenly arranged on the inner wall of the driven housing 301. The inside of the third sliding groove 302 is slidably connected with a second slider 303, the top of the second slider 303 is fixedly connected with a sliding rod 304, the side of the second slider 303 is provided with a second limiting groove 306, the side of the second slider 303 away from the second limiting groove 306 is fixedly connected with a second limiting block 307, and the side of the second slider 303 away from the second limiting groove 306 is fixedly connected with a second spring 305.

[0037] The second slider 303 is elastically connected to the inner wall of the driven housing 301 through the second spring 305. There are six second sliders 303. The size of the second limit block 307 is adapted to the size of the second limit groove 306. The six second sliders 303 are combined to form a flat plate. A tailings discharge chute 207 is provided at the bottom of the driven housing 301. The slide rod 304 is slidingly connected to the second slide groove 209. The six baffles 101 are respectively located above the six second sliders 303. The bottom of the anti-collision pad 107 is against the top of the second slider 303. The third slide groove 302 and the second slide groove 209 are staggered.

[0038] The main mechanism 4 includes a main shell 401, a concentrate discharge port 402 and a tailings discharge port 403 are arranged at the bottom of the main shell 401, a top cover 404 is arranged at the top of the main shell 401, a feed port 405 and a water injection port 406 are arranged at the top of the top cover 404, the tailings discharge port 403 is located below the tailings discharge chute 207, the concentrate discharge port 402 is located below the concentrate discharge hole 205, the motor 201 is fixedly connected to the bottom of the main shell 401, the first gear 202 passes through the bottom of the main shell 401 and extends to the interior of the main shell 401, the first gear 202 and the second gear 203 are both rotatably connected to the inner wall of the main shell 401, the water injection port 406 is located above the motor 201, and the feed port 405 is located above the tailings discharge chute 207.

[0039] The above scheme is adopted: by setting the cooperation of the driven housing 301 and the second slider 303 and other structures, the tailings are discharged conveniently. During the rotation of the drum 204, the second slide groove 209 drives the slide bar 304 to rotate around the tailings discharge chute 207, and the bottom of the second slider 303 slides with the third slide groove 302 to move it toward the direction close to the second spring 305. During the movement of the second slider 303, the six second sliders 303 are combined to form a central position of the flat plate with an empty slot, and the second slider 303 and the third slide groove 302 are connected. The sliding of the third slide groove 302 will squeeze the second spring 305, and the elastic force of the second spring 305 will drive the driven housing 301 to rotate inside the rotating groove 208. The rotation of the driven housing 301 will reduce the sliding distance of the second slider 303 in the third slide groove 302, and make the rotation speed of the driven housing 301 slower than the rotation of the second slider 303, thereby preventing the second slider 303 from moving faster inside the third slide groove 302 and causing the empty slot to expand faster, causing the tail material to be discharged before the material selection and stratification are completed, resulting in incomplete material selection.

[0040] The working principle and use process of the present invention are as follows: first, the ore pulp is injected into the interior of the main housing 401 through the feed port 405, and then the motor 201 is started to rotate the first gear 202. The rotation of the first gear 202 drives the second gear 203 to rotate. The rotation of the second gear 203 drives the drum 204 to rotate inside the main housing 401. The rotation of the drum 204 causes the ore pulp inside thereof to be subjected to a huge centrifugal force, so that the particles with high density in the slurry are pressed against the chamber wall to form a concentrated layer, while the light particles move toward the center with the water flow. Since the centrifugal force is much greater than the gravity, the heavy minerals gather on the chamber wall, while the light minerals are located at the center of the drum 204 with the water flow.

[0041] During the rotation of the drum 204, the second chute 209 drives the slide bar 304 to rotate around the tailings discharge chute 207, and causes the bottom of the second slider 303 to slide with the third chute 302 to move toward the second spring 305. During the movement of the second slider 303, an empty slot will appear at the center of the flat plate formed by the combination of the six second sliders 303. The sliding of the second slider 303 and the third chute 302 will squeeze the second spring 305, and the elastic force of the second spring 305 will drive the driven housing 301 to rotate inside the rotating groove 208. The rotation of the driven housing 301 will reduce the sliding distance of the second slider 303 inside the third chute 302, and make the rotation speed of the driven housing 301 slower than the rotation of the second slider 303.

[0042] During the movement of the second slider 303, the bottom of the anti-collision pad 107 will gradually release the contact with the second slider 303. When the rotation speed of the drum 204 reaches the discharge speed, the device completes the selection and stratification through centrifugal force. At this time, the top of the second slider 303 and the bottom of the anti-collision pad 107 are completely released. At this time, the baffle 101 will rotate downward under the action of gravity and centrifugal force, driving the anti-collision pad 107 to re-contact the side of the second slider 303, so that the tailings discharge chute 207 is opened. At this time, the particles with smaller density at the center of the drum 204 will pass through the tailings discharge chute 207 with the water flow. 7 is discharged from the tailings discharge port 403. During this process, the baffle 101 rotates toward the second slider 303 under the impact of water flow pressure and particles, so that the baffle 101 moves toward the connecting plate 104. At this time, the first slider 108 slides with the first slide groove 105, and the inclined plate 103 slides with the inclined groove 102. At the same time, the piston rod 110 squeezes the gas inside the sealing groove 112 and the first spring 111. The impact force is buffered by the air pressure and the elastic force of the first spring 111, and the baffle 101 is supported, so as to avoid the impact causing wear to the second slider 303;

[0043] Finally, the motor 201 is stopped to stop the drum 204 from rotating, and the second slider 303 is reset under the elastic force of the second spring 305, and at the same time, the inclined surface of the connecting plate 104 is pressed to make the baffle 101 rotate upward and reset to the position as shown in FIG. Figure 2 In the initial position shown, the tailings discharge chute 207 is sealed, and the concentrate discharge hole 205 is aligned with the concentrate discharge port 402, then the electronic valve 206 is opened and water is injected into the main shell 401 through the water injection port 406, so that the particles with higher density are discharged from the concentrate discharge port 402 with the water flow.
