The ore is placed on the filter plate of the ore dressing barrel and rotated for screening. The qualified material is generally screened by the filter plate aperture and discharged from the discharge pipe, while the large volume of material deposited above the filter plate generally requires people to insert tools or limbs into the barrel to remove it, which makes it difficult to remove. Summary of the Invention

[0003] The object of the present invention is to provide a rotary ore dressing machine.

[0004] The technical problems of the present invention are mainly solved by the following technical solutions:

[0005] A rotary ore concentrator comprises a barrel, wherein a discharge pipe is provided on the bottom of the barrel side wall, and a feed pipe is provided on the top cover plate.

[0006] A circular tube extending to the bottom of the barrel is provided in the middle of the barrel body, wherein a filter plate is provided at the top of the circular tube, and a circular plate is also provided in the top opening of the circular tube, and a circle of arc grooves are correspondingly provided on the outer arc wall of the circular plate and the inner wall of the circular tube, wherein a number of steel balls are provided in the two groups of arc grooves, and a polygonal through hole is also provided in the middle of the circular plate, wherein a vertical tube is provided in the through hole, and the bottom end of the vertical tube extends into the circular tube, wherein multiple groups of discharge ports are vertically provided on the outer side wall of the vertical tube in the circular tube, and a mounting hole for the top of the vertical tube to pass through is provided on the filter plate, wherein a circle of extrusion parts is provided on the vertical tube above the filter plate, and the top of the vertical tube is sealed and driven by a motor, and the cover plate accommodates the mounting opening for the up and down movement of the box body, wherein the motor is provided in the box body, and a mounting bracket connected to the box body is also provided above the cover plate, and the mounting bracket is driven by an electric push rod.

[0007] Preferably, a circle of annular seats is provided on the inner wall of the barrel body and is located below the filter plate, wherein the top of the annular seat is evenly provided with a receiving groove with a cross-section of a superior arc, and the receiving groove is provided with a ball with the top end extending to the outside and abutting against the bottom edge of the filter plate, wherein the side wall at the edge of the filter plate is a solid structure.

[0008] Preferably, the height of the top of the filter plate gradually increases from the middle toward the edge.

[0009] Preferably, the size of the vertical pipe is adapted to the size of the through hole and the mounting hole, wherein a circle of limiting parts is provided on the vertical pipe below the discharge port.

[0010] Preferably, a plurality of groups of strip plates are radially arranged on the top of the filter plate.

[0011] The beneficial effect of the present invention is that the motor in the present invention drives the vertical tube to rotate, and the vertical tube drives the filter plate to rotate in the barrel body by resisting the side wall of the mounting hole. When the filter plate rotates under the influence of the vertical tube, the filter plate can drop the qualified sieve in the material above it, while the large volume material continues to accumulate on its top. When the large volume material above the filter plate needs to be discharged, the electric push rod drives the mounting frame to drive the box body to move upward in the mounting opening. At this time, the box body drives the vertical tube upward through the motor to drive the discharge port to move to above the filter plate. When the bottom end of the discharge port is flush with the top end of the filter plate, the material on the top of the filter plate can flow along its inclined surface to the discharge port, and finally enter the vertical tube and be discharged to the collection box below it by the circular tube. Of course, at this time, the motor can also drive the vertical tube to drive the filter plate to rotate at a low speed to swing the material above the filter plate so that it can quickly enter the vertical tube through the discharge port and be discharged.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] A rotary ore concentrator comprises a barrel 1, wherein a discharge pipe is provided at the bottom of the side wall of the barrel 1, and a feed pipe is provided on the top cover plate 2.

[0019] A circular tube 3 extending to the bottom of the barrel 1 is provided in the middle, wherein a filter plate 4 is provided at the top of the circular tube 3, and a circular plate 5 is further provided in the top opening of the circular tube 3. A circle of arc grooves is provided on the outer arc wall of the circular plate 5 and the inner wall of the circular tube 3, wherein a number of steel balls 6 are provided in the two groups of arc grooves. A polygonal through hole 7 is further provided in the middle of the circular plate 5, wherein a vertical tube 8 is provided in the through hole 7, and the bottom end of the vertical tube 8 extends into the circular tube 3, wherein the outer side of the vertical tube 8 in the circular tube 3 There are multiple groups of discharge ports 18 vertically arranged on the wall, and the filter plate 4 is provided with a mounting hole 9 for the top end of the vertical pipe 8 to pass through, wherein a circle of extrusion part 10 is provided on the vertical pipe 8 above the filter plate 4, and the top end of the vertical pipe 8 is sealed and driven by a motor 11. The cover plate 2 has a mounting opening for accommodating the up and down movement of the box body 12, wherein the motor 11 is arranged in the box body 12, and a mounting bracket 13 connected to the box body 12 is also provided above the cover plate 2, and the mounting bracket 13 is driven by an electric push rod 14.

[0020] like Figure 1 As shown, a circle of annular seats 15 are provided on the inner wall of the barrel body 1 and located below the filter plate 4, wherein the top of the annular seat 15 is evenly provided with a receiving groove with a cross-section of a superior arc, and the receiving groove is provided with a ball 16 with the top extending to the outside and abutting against the bottom edge of the filter plate 4, wherein the side wall at the edge of the filter plate 4 is a solid structure.

[0021] The annular seat 15 and the balls 16 support and fix the edge of the filter plate 4 to improve its stability. At the same time, when the filter plate 4 rotates, the balls 16 can be driven to rotate in the receiving groove, thereby reducing the resistance caused by the balls to the rotation of the filter plate 4.

[0022] In this embodiment, the height of the top of the filter plate 4 gradually increases from the middle toward the edge. When the vertical pipe 8 drives the discharge port 18 to move above the filter plate 4, the material on the top of the filter plate 4 can easily flow along the inclined surface toward the middle, and finally flow into the vertical pipe 8 through the discharge port 18 and be discharged.

[0023] In this embodiment, the size of the vertical tube 8 is adapted to the size of the through hole 7 and the mounting hole 9. A stopper 17 is provided on the vertical tube 8 below the discharge port 18. This allows the vertical tube 8 to rotate by abutting against the side walls of the through hole 7 and the mounting hole 9, thereby driving the corresponding filter plate 4 and circular plate 5 to rotate.

[0024] In this embodiment, a plurality of strip plates are radially arranged on the top of the filter plate 4. When the filter plate 4 rotates, the strip plates can drive the top materials to rotate together, thereby allowing the filter plate 4 to cause the top materials to fall through the aperture screen during the rotation process.

[0025] When in use, the annular seat 15 and the ball 16 support the edge of the filter plate 4, and the output shaft of the motor 11 exerts a downward squeezing effect on the middle of the filter plate 4 through the vertical tube 8 and the squeezing part 10, thereby preventing the filter plate 4 from moving up and down in the barrel body 1;

[0026] The material is introduced into the barrel body 1 above the filter plate 4, and the motor 11 drives the vertical pipe 8 to rotate, and the vertical pipe 8 drives the filter plate 4 to rotate in the barrel body 1 by abutting against the side wall of the mounting hole 9. At this time, the vertical pipe 8 also drives the arc groove on the circular plate 5 to rotate on the steel ball 6 by abutting against the side wall of the through hole 7, so that it does not affect the rotation of the vertical pipe 8. When the filter plate 4 is rotated under the influence of the vertical pipe 8, the filter plate 4 can drop the qualified sieve in the material above it, while the large volume of material continues to accumulate on its top. In the above process, the circular plate 5 prevents the material above the filter plate 4 from falling into the circular pipe 3 when the sieve falls, and at this time the discharge port 18 is located in the circular pipe 3, so that the material above the filter plate 4 will not flow out through it.

[0027] like Figure 1 As shown, the material sieved and falling at the bottom of the barrel body 1 is discharged through the discharge pipe. When the large volume of material above the filter plate 4 needs to be discharged, the electric push rod 14 drives the mounting frame 13 to drive the box body 12 to move upward in the mounting opening. At this time, the box body 12 drives the vertical pipe 8 upward through the motor 11 to drive the discharge port 18 to move above the filter plate 4. At the same time, the vertical pipe 8 will also drive the limit part 17 to move upward and contact the circular plate 5 to prevent the vertical pipe 8 from moving upward excessively. When the bottom end of the discharge port 18 is flush with the top end of the filter plate 4, the material on the top of the filter plate 4 can flow along its inclined surface to the discharge port, and finally enter the vertical pipe 8 and be discharged from the circular pipe 3 to the collection box below it. Of course, at this time, the motor 11 can also drive the vertical pipe 8 to drive the filter plate 4 to rotate at a low speed to swing the material above the filter plate 4 so that it can quickly enter the vertical pipe 8 through the discharge port 18 and be discharged.

[0028] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
