Description

Technical Field

[0001] The present invention belongs to the technical field of thickeners, and specifically relates to a thickener with defoaming and sedimentation functions. Background Art

[0002] A thickener is a solid-liquid separation device widely used in the mining, metallurgy, chemical, and environmental protection industries. It is mainly used to increase the solid concentration of pulp or industrial slurry, achieving efficient sedimentation and clarification of overflow. Its core working principle is based on gravitational sedimentation. By slowly stirring, it promotes the aggregation and compression of solid particles to form a high-concentration underflow, while discharging the clarified overflow water for recycling.

[0003] First of all, the foaming agents remaining in the flotation process (such as surfactants like pine oil and alcohols) will significantly reduce the liquid surface tension, promoting the formation and stability of bubbles. Gas is involved during the pulp transportation process due to pipeline turbulence, pumping, or high-position dropping, and the eddies generated during the operation of the stirring device (such as the rake frame) entrain air. The accumulation of bubbles forms a foam layer, which will hinder the normal sedimentation of solid particles, resulting in reduced sedimentation efficiency and insufficient underflow concentration. At the same time, the foam carries fine particles into the overflow, causing the overflow water quality to be turbid and affecting the recycling of the return water.

[0004] For example, in the disclosed patent: CN118807273A defoaming and sedimentation thickener, in this invention, the hair roller is partially immersed under the liquid surface, and the rake frame drives the hair roller to revolve, so that the foam relatively converges in front of the hair roller, making the foam on the liquid surface fully converge into the defoaming process, facilitating the full defoaming of the thickening tank; the hair roller rotates in a form of partial immersion under the liquid surface and rolling forward, so that the foam in front of the hair roller is punctured, cut, or pressed into the liquid to dissolve and break, making the foam effectively and quickly break.

[0005] However, when the above hair roller breaks the foam, some foaming agents and oily substances may adhere to the surface of the bristles after the foam breaks. The oily substances may cause adjacent bristles to stick together in bundles. When the brush rotates, the adhered part cannot swing freely, which will reduce the shearing force on the foam, thereby reducing the foam breaking efficiency.

[0006] Therefore, the present invention provides a thickener with defoaming and sedimentation functions. Summary of the Invention

[0007] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

The other end of the first water pipe is communicated with the inside of the thickener body, and the other end of the second water pipe is communicated with the cleaning box. One-way valves are arranged on both the first water pipe and the second water pipe.

[0013] The bottom end of the rotating shaft is provided with a water-permeable box. The other end of the first water pipe penetrates through the rotating shaft and extends into the water-permeable box. A water pressure groove for the cleaning box to slide is opened inside the placement box, and the other end of the second water pipe extends into the water pressure groove.

[0014] A driving motor is fixedly installed on the top end of the fixed platform. The output shaft of the driving motor is fixedly connected with a transmission rod. A first bevel gear is rotatably installed on the transmission rod. A sliding rod is fixedly installed at the bottom end of the piston. A reciprocating lead screw is connected to the inside of the sliding rod by threads. The bottom end of the reciprocating lead screw is fixedly installed with a second bevel gear meshing with the first bevel gear.

[0015] A rotating block is fixedly installed on one side of the first bevel gear. A ratchet wheel is rotatably installed inside the rotating block. A ratchet rod for blocking the ratchet wheel is elastically installed inside the rotating block. The ratchet wheel is fixedly installed on the outer wall of the transmission rod.

[0016] One end of the transmission rod extends into the processing roller and is elastically installed with a clamping block. A clamping groove for the clamping block to engage is opened inside the processing roller. One end of the clamping block is inclined.

[0017] Connecting rods are fixedly connected to the side walls of the two cleaning plates. Guide rods are fixedly installed on the side walls of the connecting rods. A control disk is rotatably installed inside the cleaning box. A dial rod for pushing the guide rod is fixedly installed at the bottom end of the control disk.

[0018] A diversion pipe is fixedly installed inside the cleaning box. One end of the diversion pipe extends into the water pressure groove and is provided with a water inlet hole. A return spring is arranged between the top end of the cleaning box and the top end inside the water pressure groove.

For the thickener with the functions of defoaming and ore settling described in the present invention, through the water inlet holes opened on the diversion pipe, the water entering the water pressure tank can be sent into the cleaning box. While the water flows through, the water turbine blades can be impacted, so that the water turbine blades drive the rotating rod to rotate. At this time, the control disk will drive the lever to push the guide rods on the two cleaning plates in sequence, and with the cooperation of the connecting springs, the two cleaning plates will slide left and right in sequence, thereby further improving the cleaning effect on the brush bristles.

Specific embodiments

[0035] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figures 1 to 11 shown, a thickener with defoaming and ore-settling functions according to an embodiment of the present invention includes a thickener body 1. A rotating shaft 2 is rotatably installed inside the thickener body 1. A placement box 3 is fixedly installed on the rotating shaft 2. One end of the placement box 3 is open. A water leakage port 20 is provided on the placement box 3. A treatment roller 10 is rotatably installed inside the placement box 3. A row brush is fixedly installed on the treatment roller 10;

[0037] The rotating shaft 2 can be driven by a motor and is used to drive the placement box 3 to rotate inside the thickener body 1 through the rotating shaft 2. The bottom end of the placement box 3 extends below the liquid level. When the placement box 3 rotates, the bubbles floating in the thickener body 1 can be scraped into the inside of the placement box 3. Since the water leakage port 20 is provided on the placement box 3, when scraping the foam into the inside of the placement box 3, the water flow will not be blocked, thus affecting the entry of the foam.

[0038] The brush row is fixedly installed on the outer wall of the treatment roller 10. There are bristles on the brush row. There are multiple brush rows, and the multiple brush rows are arranged in a ring on the outer wall of the treatment roller 10. One end of the bristles extends below the liquid level, and the bristles also fit against the inner wall of the placement box 3. Therefore, when controlling the rotation of the treatment roller 10, it is more convenient to pierce the foam scraped into the interior of the placement box 3.

[0039] A cleaning box 22 is slidably installed inside the placement box 3. Two cleaning plates 25 for cleaning the brush row are slidably installed inside the cleaning box 22, and the two cleaning plates 25 are symmetrically arranged;

[0040] The bottom of the cleaning box 22 is open, and the cross-section of the cleaning box 22 is an inverted C shape. The cleaning box 22 can be retracted inside the placement box 3 without affecting the rotation of the treatment roller 10 driving the brush row. When the bristles need to be cleaned, control the treatment roller 10 to rotate one of the brush rows and the bristles to directly below the cleaning box 22. At this time, control the cleaning box 22 to slide downward until the brush row is located between the inner walls of the cleaning box 22. At the same time, the two cleaning plates 25 will be located on both sides of the bristles. By sliding the two cleaning plates 25, the middle bristles can be rubbed, and the bristles stuck together due to oily substances can be separated.

[0041] The cleaning box 22 has a cavity. One end of the cleaning box 22 close to the cleaning plate 25 is provided with a water outlet 24, and the bottom end of the cleaning box 22 is provided with a drain port 26;

[0042] A fixed platform 4 is fixedly installed on the rotating shaft 2. A water supply component is arranged on the fixed platform 4 for sending the water in the thickening tank body 1 into the interior of the cleaning box 22.

[0043] When the cleaning box 22 is sleeved on the brush row, at this time, the water is conveyed into the interior of the cleaning box 22 through the water supply component. At this time, when the two cleaning plates 25 rub the bristles (the cleaning plates 25 can be silica gel plates), the water entering the cleaning box 22 can enter between the two cleaning plates 25 through the water outlet 24 to assist the two cleaning plates 25 in cleaning the oily substances on the brush, and the sewage can be discharged through the drain port 26.

[0044] An electric heating wire can also be arranged inside the cleaning box 22 to heat up the water entering the cleaning box 22. The heated water can further improve the treatment effect on the oily substances. By cleaning the bristles, the situation of the bristles sticking is reduced, the contact area between the bristles and the foam can be increased, the shearing force on the foam can be improved, and thus the crushing efficiency of the foam can be improved.

[0045] As a preferred embodiment of the present invention, the water delivery assembly includes a water delivery cylinder 6, a piston 13, a first water pipe 7 and a second water pipe 8. The water delivery cylinder 6 is fixedly installed on the side wall of the placement box 3, the piston 13 is slidably installed inside the water delivery cylinder 6, both the first water pipe 7 and the second water pipe 8 are fixedly installed on the outer wall of the water delivery cylinder 6. The other end of the first water pipe 7 is communicated with the inside of the thickener body 1, and the other end of the second water pipe 8 is communicated with the cleaning box 22. One-way valves are provided on both the first water pipe 7 and the second water pipe 8.

[0046] The one-way valve provided on the first water pipe 7 only allows the water in the thickener body 1 to enter the water delivery cylinder 6.

[0047] The one-way valve provided on the second water pipe 8 only allows the water in the water delivery cylinder 6 to enter the second water pipe 8.

[0048] Therefore, when the piston 13 slides downward from top to bottom inside the water delivery cylinder 6, the water inside the thickener body 1 can be pumped into the water delivery cylinder 6 through the first water pipe 7. Subsequently, when the piston 13 slides upward from bottom to top inside the water delivery cylinder 6, the water inside the water delivery cylinder 6 can be sent into the cleaning box 22 through the second water pipe 8.

[0049] As a preferred embodiment of the present invention, a water permeable box 9 is provided at the bottom end of the rotating shaft 2. The other end of the first water pipe 7 penetrates through the rotating shaft 2 and extends into the interior of the water permeable box 9. A water pressure groove 21 for the cleaning box 22 to slide is opened inside the placement box 3, and the other end of the second water pipe 8 extends into the interior of the water pressure groove 21.

[0050] The water permeable box 9 has a cavity and is provided with a plurality of holes on the outside. The first water pipe 7 extends into the interior of the water permeable box 9, and the clear water in the thickener body 1 can be pumped in. The water sucked into the first water pipe 7 can be filtered through the opened holes.

[0051] The second water pipe 8 sends water into the interior of the water pressure groove 21. As the water accumulates inside the water pressure groove 21, the cleaning box 22 can be pushed downward inside the water pressure groove 21 under the action of water pressure. At this time, the cleaning box 22 can be sleeved on the brush.

[0052] As a preferred embodiment of the present invention, a driving motor 5 is fixedly installed at the top end of the fixed platform 4. The output shaft of the driving motor 5 is fixedly connected with a transmission rod 14. A first bevel gear 18 is rotatably installed on the transmission rod 14. A sliding rod 12 is fixedly installed at the bottom end of the piston 13. A reciprocating lead screw 11 is threadedly connected inside the sliding rod 12. The bottom end of the reciprocating lead screw 11 is fixedly installed with a second bevel gear 19 that meshes with the first bevel gear 18.

[0053] When the driving motor 5 rotates, the first bevel gear 18 can be driven to rotate through the transmission rod 14. At the same time, the second bevel gear 19 drives the reciprocating lead screw 11 to rotate. At this time, the sliding rod 12 can reciprocate up and down on the outer wall of the reciprocating lead screw 11, and at the same time drive the piston 13 to reciprocate inside the water delivery cylinder 6, and cooperate with the first water pipe 7 and the second water pipe 8 to pump out the water in the thickener body 1, and send it into the inside of the cleaning box 22 through the second water pipe 8 for cleaning the brush bristles.

[0054] As a preferred embodiment of the present invention, a rotating block 15 is fixedly installed on one side of the first bevel gear 18. A ratchet wheel 16 is rotatably installed inside the rotating block 15. A ratchet lever 17 for blocking the ratchet wheel 16 is elastically installed inside the rotating block 15. The ratchet wheel 16 is fixedly installed on the outer wall of the transmission rod 14.

[0055] Through the arrangement of the ratchet lever 17, the clockwise rotation of the ratchet wheel 16 can be blocked, and at the same time, the clockwise rotation of the transmission rod 14 can also be blocked.

[0056] When the driving motor 5 drives the transmission rod 14 to rotate clockwise, through the arrangement of the ratchet lever 17, the rotating block 15 can be driven to rotate clockwise. At this time, the first bevel gear 18 also drives the second bevel gear 19 to rotate, so that the reciprocating lead screw 11 rotates. At this time, the sliding rod 12 can reciprocate up and down on the outer wall of the reciprocating lead screw 11, and at the same time drive the piston 13 to reciprocate inside the water delivery cylinder 6, and cooperate with the first water pipe 7 and the second water pipe 8 to pump out the water in the thickener body 1, and send it into the inside of the cleaning box 22 through the second water pipe 8 for cleaning the brush bristles.

[0057] When the driving motor 5 rotates counterclockwise, at this time the ratchet lever 17 does not block the ratchet wheel 16. Therefore, when the transmission rod 14 rotates counterclockwise, it cannot drive the first bevel gear 18 to rotate.

[0058] As a preferred embodiment of the present invention, one end of the transmission rod 14 extends into the inside of the processing roller 10, and a clamping block 33 is elastically installed. A clamping groove 34 for the clamping block 33 to engage is opened inside the processing roller 10. One end of the clamping block 33 is inclined.

[0059] Through the inclined clamping block 33, when the transmission rod 14 rotates clockwise, through the pressing of the inclined surface of the clamping block 33 against the clamping groove 34, the clamping block 33 can be pushed into the inside of the transmission rod 14. At this time, the transmission rod 14 cannot drive the processing roller 10 to rotate clockwise synchronously.

[0060] Through the cooperation of the flat part of the clamping block 33 and the clamping groove 34, the transmission rod 14 can drive the processing roller 10 to rotate counterclockwise.

[0061] When it is necessary to clean the bristles on the processing roller 10, it is necessary to control the driving motor 5 to rotate counterclockwise to control the processing roller 10 to rotate one of the row brushes to directly below the cleaning box 22 (the control method of the driving motor 5 is a common technical means for those skilled in the art, so it will not be elaborated here). At this time, by controlling the driving motor 5 to rotate clockwise, through the setting of the ratchet rod 17, the rotating block 15 can be driven to rotate clockwise. At this time, the first bevel gear 18 will also drive the second bevel gear 19 to rotate, causing the reciprocating lead screw 11 to rotate. At this time, the sliding rod 12 can reciprocate up and down on the outer wall of the reciprocating lead screw 11, and at the same time drive the piston 13 to reciprocate inside the water delivery cylinder 6, and cooperate with the first water pipe 7 and the second water pipe 8 to pump out the water in the thickening tank body 1 and send it into the cleaning box 22 through the second water pipe 8 for cleaning the bristles.

[0062] As a preferred embodiment of the present invention, connecting rods 29 are fixedly connected to the side walls of both cleaning plates 25. Guide rods 31 are fixedly installed on the side walls of the connecting rods 29. A control disk 30 is rotatably installed inside the cleaning box 22. A lever 32 for pushing the guide rod 31 is fixedly installed at the bottom end of the control disk 30.

[0063] A diversion pipe 23 is fixedly installed inside the cleaning box 22. One end of the diversion pipe 23 extends into the water pressure tank 21 and is provided with a water inlet hole. A return spring is provided between the top end of the cleaning box 22 and the inner top end of the water pressure tank 21.

[0064] Through the arranged return spring, the cleaning box 22 can always be kept away from the row brush on the processing roller 10.

[0065] A water wheel blade 28 is rotatably installed inside the diversion pipe 23. The bottom end of the water wheel blade 28 is fixedly connected to a rotating rod 27. One end of the rotating rod 27 penetrates through the diversion pipe 23 and is fixedly connected to the control disk 30.

[0066] Both connecting rods 29 are installed inside the cleaning box 22 through connecting springs.

[0067] When the water delivery cylinder 6 sends water into the water pressure tank 21 through the second water pipe 8, under the action of water pressure, the cleaning box 22 will be pushed downward until the water in the water pressure tank 21 can enter the inner cavity of the cleaning box 22 through the water inlet hole on the diversion pipe 23. At the same time, when the water flows through, the water wheel blade 28 can be impacted, causing the water wheel blade 28 to drive the rotating rod 27 to rotate. At this time, the control disk 30 will drive the lever 32 to push the guide rods 31 on both cleaning plates 25 in turn, and with the cooperation of the connecting spring, the two cleaning plates 25 will slide left and right in turn, thereby further improving the cleaning effect on the bristles.

[0068] Working principle: When it is necessary to clean the bristles on the processing roller 10, control the driving motor 5 to rotate counterclockwise to control the processing roller 10 to rotate one of the row brushes to directly below the cleaning box 22, and then control the driving motor 5 to rotate clockwise. Through the setting of the ratchet rod 17, the rotating block 15 can be driven to rotate clockwise. At this time, the first bevel gear 18 will also drive the second bevel gear 19 to rotate, causing the reciprocating lead screw 11 to rotate. At this time, the sliding rod 12 can slide up and down reciprocally on the outer wall of the reciprocating lead screw 11, and at the same time drive the piston 13 to slide reciprocally inside the water delivery cylinder 6. In cooperation with the first water pipe 7 and the second water pipe 8, the water in the thickening tank body 1 can be pumped out and sent into the water pressure tank 21 through the second water pipe 8. Under the action of water pressure, the cleaning box 22 will be pushed downward until the water in the water pressure tank 21 can enter the inner cavity of the cleaning box 22 through the water inlet holes on the diversion pipe 23. At the same time, when the water flows through, the water turbine blades 28 can be impacted, causing the water turbine blades 28 to drive the rotating rod 27 to rotate. At this time, the control disk 30 will drive the shift lever 32 to push the guide rods 31 on the two cleaning plates 25 in sequence, and with the cooperation of the connecting springs, the two cleaning plates 25 will slide left and right in sequence, thereby further improving the cleaning effect on the bristles. By cleaning the bristles and reducing the sticking of the bristles, the contact area between the bristles and the foam can be increased, the shearing force on the foam can be improved, and thus the crushing efficiency of the foam can be improved.
