Description

Technical Field

[0001] This utility model belongs to the technical field of mining equipment, specifically a feeding structure for a thickener. Background Technology

[0002] Mining thickeners are key pieces of equipment in industrial fields such as mineral processing plants and coal washing plants, mainly used for solid-liquid separation of slurries containing solid particles. Their core function is to concentrate thin mineral slurries into high-concentration underflow through the principle of gravity sedimentation, while simultaneously obtaining clarified overflow water, thereby achieving water resource recycling and efficient recovery of valuable minerals.

[0003] A thickener typically consists of a large, circular thickening tank and a slowly rotating rake frame. The slurry is fed into the center of the tank, and the solid particles gradually settle to the bottom under gravity, where they are scraped by the rotating rake frame and discharged through the central discharge port; the clarified overflow water flows out from the overflow weir at the top of the tank wall.

[0004] Patent document CN204246887U describes a mining thickener, including a thickening tank, an electric motor, a transmission device, and a rake frame. The rake frame is connected to the electric motor via the transmission device, and under the action of the electric motor, the rake frame reciprocates within the thickening tank. The rake frame is equipped with rake teeth, and partitions are provided between the rake teeth. Both the partitions and the rake frame have through cavities, and the through cavities of the partitions and the rake frame are connected. A small cylinder is installed within the through cavity of the rake frame, and a telescopic rod is installed within the through cavity of the partition. The telescopic rod is fixed to the piston shaft of the small cylinder. A control cam is provided on the transmission device, and the control cam is connected to the control end of the small cylinder via a wire.

[0005] Existing mining thickeners have certain shortcomings in use. Mining thickeners mainly achieve solid-liquid separation through the principle of gravity sedimentation. When the slurry enters the circular thickening tank directly, the slurry contains a large number of large particles of impurities, which increases the time required for solid-liquid separation. At the same time, the impact of the slurry on the bottom of the thickening tank will cause the already settled solid particles to be remixed. The impact can only be reduced by controlling the flow rate, which reduces the effectiveness of the thickener. Utility Model Content

[0006] This utility model provides a feeding structure for a thickener, which can solve the problem that existing mining thickeners mainly achieve solid-liquid separation through gravity sedimentation. When the slurry directly enters the circular thickening tank, the slurry contains a large number of large particles of impurities, which increases the time required for solid-liquid separation. At the same time, the impact of the slurry on the bottom of the thickening tank will cause the already settled solid particles to be remixed. A feeding structure for a concentrator includes a filter media box and a discharge component. The discharge component is fixedly installed on the outer surface of one end of the filter media box. A filter screen is movably installed inside the filter media box. A roller brush is movably installed on the lower surface of the filter screen. A conveying brush belt is movably installed on the upper surface of the filter screen. The discharge component includes a lower tube and an upper tube. The upper tube is fixedly installed on the outer surface of one end of the lower tube. The upper tube is located above the lower tube, and an inclined section is provided between the upper tube and the lower tube.

[0007] As a further technical solution of this utility model, a discharge nozzle is fixedly installed on the outer side surface of the filter media box, and the conveying brush belt is movably installed on the inner side of the discharge nozzle. By using the setting of the roller brush, the blockage in the filter screen can be pushed out when the filter screen moves, and the blockage on the filter screen can be discharged to one side by the movement of the conveying brush belt, so that it is discharged through one end of the discharge nozzle.

[0008] As a further technical solution of this utility model, the upper end of the discharge nozzle is provided with two sets of motors. The motors and the conveying brush belt are driven by a rotating drum. The rotating drum is driven by the motor, which in turn drives the conveying brush belt to move. The surface of the conveying brush belt is a brush structure. The cleaning operation of the first winding rod is completed through the contact between the conveying brush belt and the surface of the first winding rod.

[0009] As a further technical solution of this utility model, a first winding rod is fixedly installed at one end of the filter screen, and a second winding rod is fixedly installed at the other end of the filter screen. The rotation of the second winding rod and the first winding rod drives the filter screen to move, adjusts the position of the filter screen in the filter media box, and at the same time makes the bottom of the filter screen contact the roller brush. The roller brush pushes out the blockage stuck in the filter screen from bottom to top.

[0010] As a further technical solution of this utility model, the first winding rod and the second winding rod are symmetrically arranged, and the ends of the first winding rod and the second winding rod are provided with rotating rods. During operation, the rotating rods are driven by a motor, so that the rotating rods drive the first winding rod or the second winding rod to rotate, thereby driving the filter screen to move to one end or the other end.

[0011] As a further technical solution of this utility model, the upper part of the filter screen is provided with baffles on both sides of the conveying brush belt. The two sets of baffles are symmetrically arranged. By using the baffles, the blockages on the filter screen can be blocked, preventing the filter screen from carrying the blockages out from the lower part of the conveying brush belt during the movement, thereby improving the cleaning effect of the conveying brush belt on the blockages.

[0012] As a further technical solution of this utility model, one end of the filter media box is provided with a discharge hole for use with the discharge component, and one end of the lower pipe body is connected to the discharge port. By using the discharge component, the flow rate of the slurry when it is discharged from the filter media box can be reduced, thus avoiding secondary scouring of the sediment at the bottom of the thickener.

[0013] As a further technical solution of this utility model, support rods are fixedly installed at the bottom of both the lower pipe and the upper pipe. The two sets of support rods are at different heights, so that the support rods can support the lower pipe and the upper pipe at different heights, creating a height difference between the lower pipe and the upper pipe. When the slurry enters the upper pipe from the lower pipe, the slurry flow rate decreases.

[0014] As a further technical solution of this utility model, a number of sets of arc-shaped protrusions are fixedly installed on the inner side of the upper pipe body. The sets of arc-shaped protrusions are arranged side by side. The upper surface of the arc-shaped protrusions has an arc-shaped structure. By using the arrangement of the arc-shaped protrusions, when the slurry enters the interior of the upper pipe body, it can flow in a wave-like manner, impacting the surface of the arc-shaped protrusions and reducing the slurry flow rate.

[0015] As a further technical solution of this utility model, a slag hopper is fixedly installed on the outer side surface of the filter media box. The slag hopper is located below the discharge nozzle and can be used to collect the blockage discharged from the discharge nozzle.

[0016] The beneficial effects of this utility model are as follows: By setting up a conveyor brush belt and a roller brush, this utility model provides a filtration and cleaning structure for the feed structure of the thickener, enabling continuous slurry filtration while effectively preventing clogging. During operation, the rotation of the second and first winding rods drives the filter screen to move, adjusting its position within the filter media box. Simultaneously, the bottom of the filter screen contacts the roller brush, which pushes out blockages stuck in the filter screen from bottom to top. The baffle plate further prevents blockages from forming on the filter screen during its movement. During the process, the blockage is carried out from the bottom of the conveying brush belt, improving the cleaning effect of the conveying brush belt on the blockage. The rotating drum driven by the motor moves the conveying brush belt. The surface of the conveying brush belt has a brush structure. The first winding rod is cleaned by contact between the conveying brush belt and the surface of the first winding rod. With the setting of the roller brush, the blockage in the filter screen can be pushed out when the filter screen moves. Then, the movement of the conveying brush belt will discharge the blockage on the filter screen to one side, so that it is discharged through one end of the discharge nozzle, so that the filter screen always keeps in good working condition and removes large particles in the slurry. By setting up a discharge component, the flow rate of the slurry discharged from the filter box can be reduced when the feed structure of the thickener is used, thus avoiding secondary scouring of the sediment at the bottom of the thickener. The two sets of support rods are at different heights, so that the support rods can support the lower and upper pipes at different heights, creating a height difference between the lower and upper pipes. When the slurry enters the upper pipe from the lower pipe, the slurry flow rate decreases after passing through the inclined section. Secondly, the upper surface of the arc-shaped convex strip has an arc-shaped structure. By using the arc-shaped convex strip, when the slurry enters the interior of the upper pipe, it flows in a wave-like manner, impacting the surface of the arc-shaped convex strip and reducing the slurry flow rate.

[0021] like Figures 1-3 As shown, a feed structure for a concentrator includes a filter box 1 and a discharge component 2. The discharge component 2 is fixedly installed on the outer surface of one end of the filter box 1. A filter screen 4 is movably installed inside the filter box 1. A roller brush 9 is movably installed on the lower surface of the filter screen 4. A conveying brush belt 7 is movably installed on the upper surface of the filter screen 4. The discharge component 2 includes a lower tube body 12 and an upper tube body 13. The upper tube body 13 is fixedly installed on the outer surface of one end of the lower tube body 12. The upper tube body 13 is located above the lower tube body 12, and an inclined section is provided between the upper tube body 13 and the lower tube body 12.

[0022] A discharge nozzle 5 is fixedly installed on the outer side surface of the filter media box 1. A conveying brush belt 7 is movably installed inside the discharge nozzle 5. With the setting of the roller brush 9, the blockage in the filter screen 4 can be pushed out when the filter screen 4 moves. Then, with the movement of the conveying brush belt 7, the blockage on the filter screen 4 is discharged to one side, so that it is discharged through one end of the discharge nozzle 5.

[0023] Two sets of motors 6 are provided at the upper end of the discharge nozzle 5. The motors 6 and the conveying brush belt 7 are driven by a rotating drum. The motors 6 drive the rotating drum, which in turn moves the conveying brush belt 7. The surface of the conveying brush belt 7 is a brush structure. The cleaning operation of the first winding rod 10 is completed through the contact between the conveying brush belt 7 and the surface of the first winding rod 10.

[0024] A first winding rod 10 is fixedly installed at one end of the filter screen 4, and a second winding rod 11 is fixedly installed at the other end of the filter screen 4. By rotating the second winding rod 11 and the first winding rod 10, the filter screen 4 is driven to move, and the position of the filter screen 4 in the filter media box 1 is adjusted. At the same time, the bottom of the filter screen 4 is brought into contact with the roller brush 9, and the roller brush 9 pushes out the blockage stuck in the filter screen 4 from bottom to top.

[0025] The first winding rod 10 and the second winding rod 11 are symmetrically arranged. The ends of the first winding rod 10 and the second winding rod 11 are provided with rotating rods 16. During operation, the rotating rods 16 are driven by a motor, so that the rotating rods 16 drive the first winding rod 10 or the second winding rod 11 to rotate, thereby driving the filter screen 4 to move to one end or the other end.

[0026] The upper part of the filter screen 4 is provided with baffles 8 on both sides of the conveyor belt 7. The two sets of baffles 8 are symmetrically arranged. The baffles 8 can block the blockages on the filter screen 4, preventing the filter screen 4 from carrying the blockages out from the lower part of the conveyor belt 7 during the movement, thus improving the cleaning effect of the conveyor belt 7 on the blockages.

[0027] One end of the filter media box 1 is provided with a discharge hole for use with the discharge component 2. One end of the lower pipe body 12 is connected to the discharge port. By using the discharge component 2, the flow rate of the slurry when it is discharged from the filter media box 1 can be reduced, thus avoiding secondary scouring of the sediment at the bottom of the thickener.

[0028] Support rods 15 are fixedly installed at the bottom of both the lower pipe body 12 and the upper pipe body 13. The two sets of support rods 15 are at different heights, so that the support rods 15 can support the lower pipe body 12 and the upper pipe body 13 at different heights, creating a height difference between the lower pipe body 12 and the upper pipe body 13. When the slurry enters the upper pipe body 13 from the lower pipe body 12, the slurry flow rate decreases.

[0029] Several sets of arc-shaped protrusions 14 are fixedly installed on the inner side of the upper pipe body 13. The sets of arc-shaped protrusions 14 are arranged side by side. The upper surface of the arc-shaped protrusions 14 has an arc-shaped structure. By using the arrangement of the arc-shaped protrusions 14, when the slurry enters the interior of the upper pipe body 13, it can flow in a wave-like manner, impacting the surface of the arc-shaped protrusions 14 and reducing the slurry flow rate.

[0030] A slag hopper 3 is fixedly installed on the outer side of the filter media box 1. The slag hopper 3 is located below the discharge nozzle 5. The slag hopper 3 can be used to collect the blockage discharged from the discharge nozzle 5.

[0031] A feeding structure for a thickener, in use, incorporates a conveyor brush belt 7 and a roller brush 9. This feeding structure provides a filtration and cleaning mechanism, enabling continuous slurry filtration while effectively preventing clogging. During operation, the rotation of the second winding rod 11 and the first winding rod 10 drives the filter screen 4 to move, adjusting its position within the filter media box 1. Simultaneously, the bottom of the filter screen 4 contacts the roller brush 9, which pushes out blockages from the filter screen 4 from bottom to top. A baffle 8 further prevents blockages from forming on the filter screen 4 during its movement. The conveyor belt 7 carries out the blockage from the lower part, improving the cleaning effect of the conveyor belt 7 on the blockage. The motor 6 drives the drum, which in turn moves the conveyor belt 7. The surface of the conveyor belt 7 is a brush structure. The conveyor belt 7 cleans the first winding rod 10 by contacting the surface of the first winding rod 10. The roller brush 9 can push out the blockage in the filter screen 4 when the filter screen 4 moves. The conveyor belt 7 then moves the blockage on the filter screen 4 to one side and discharges it through one end of the discharge nozzle 5, so that the filter screen 4 is always in good working condition and removes large particles from the slurry. By setting the discharge component 2, when the feed structure of the thickener is used, the flow rate of the slurry discharged from the filter box 1 can be reduced, avoiding secondary scouring of the sediment at the bottom of the thickener. The two sets of support rods 15 have different heights, so that the support rods 15 can support the lower pipe 12 and the upper pipe 13 at different heights, creating a height difference between the lower pipe 12 and the upper pipe 13. When the slurry enters the upper pipe 13 from the lower pipe 12, the slurry flow rate is reduced after passing through the inclined section. Secondly, the upper surface of the arc-shaped protrusion 14 has an arc-shaped structure. By using the setting of the arc-shaped protrusion 14, when the slurry enters the interior of the upper pipe 13, it flows in a wave-like manner, impacting the surface of the arc-shaped protrusion 14 and reducing the slurry flow rate.

[0032] The above description is merely an example and illustration of the structure of this utility model.
