[0003] The desludging device for mining and mineral processing is a device used to separate and remove impurities (usually the finer particle size) such as fine clay and silt on the surface of ore particles or in the ore pulp during ore mining and mineral processing.

It also helps to protect mineral processing equipment and extend the service life of equipment.

[0004] However, the current desludging devices for mining and mineral processing have the following shortcomings: 1. Since the ore slurry contains silt and minerals, it is easy for silt to clog the filter components if it is simply treated by centrifugation; 2.

[0035] See also Figures 1 to 7The present invention provides a technical solution: a desludging device for mining and mineral processing, comprising a main body 1, a U-shaped groove 2 is fitted on the top of the main body 1, a diverter box 3 is arranged at one end of the main body 1, a hydrocyclone 4 is arranged between the main body 1 and the diverter box 3, and the main body 1 is connected to the water inlet of the hydrocyclone 4 through a pipeline, a stirring member 5 is rotatably connected inside the U-shaped groove 2, a first driving gear 6 is rotatably connected to the outer wall of one side of the U-shaped groove 2, and the first driving gears 6 are meshed and connected, a sieve plate 7 is slidably connected inside the main body 1 through a slider, a plurality of nozzles 8 distributed at equal distances are connected to the inner top wall of the main body 1 through a pipeline, a cam 9 is rotatably connected inside the main body 1, the nozzle 8 and the cam 9 are respectively located above and below the sieve plate 7, and the cam 9 is fitted to the bottom of the sieve plate 7, and the inner walls of the main body 1 are rotatably connected to the diverter box 3. The separation belt 10 is provided, and one end of the separation belt 10 is adjacent to and below one end of the sieve plate 7. The outer wall of one side of the main body 1 and the position of the corresponding cam 9 inside the main body 1 are rotatably connected with a synchronous belt 11. The inner bottom wall of the main body 1 is fitted with a sedimentation rack 12, and the sedimentation rack 12 is located below the cam 9. The inner wall of one side of the main body 1 is rotatably connected with a pulley 13, and the pulley 13 is connected to the sedimentation rack 12 by a pull rope 14. The upper net belt 15 and the lower net belt 16 are rotatably connected between the inner walls of the diverter box 3, respectively, and the upper net belt 15 is located above the lower net belt 16. The outer wall of the diverter box 3 is rotatably connected with a second driving gear 18, and the second driving gears 18 are meshed with each other. One end of the diverter box 3 is fixedly connected with a guide plate 19, and the other end of the diverter box 3 is fixedly connected with a drainage trough 20, and the drainage trough 20 is connected to the water outlet of the hydrocyclone 4 through a pipeline.

[0036] The stirring element 5 is composed of a roller body 501, a blade group 502 and a mud groove 503. The mud groove 503 and the blade group 502 are equiangular and distributed on the outer wall of the roller body 501 in a staggered structure. One end of the mud groove 503 is rotatably connected to a fan-shaped panel 504.

[0037] A support rod 1201 is fixedly connected to the top of one end of the precipitation rack 12, and a movable plate 1202 is rotatably connected to the other end of the precipitation rack 12.

[0038] In this embodiment, Figure 1 and Figure 2As shown, the U-shaped trough 2 is integrally connected to the main body 1 through a frame via bolts, and the U-shaped trough 2 is fitted and erected on the top of the main body 1 at an inclined angle of 10°, and the main body 1 and the lower end of the U-shaped trough 2 are fitted with a through slot; compared with the traditional horizontally arranged trough structure, the inclination angle allows the material to flow naturally toward the main body 1 under the action of gravity, avoiding the accumulation of materials inside the U-shaped trough 2, ensuring the continuity of the processing flow, so that the slurry is not only affected by the stirring force of the stirring member 5, but also by the component force of gravity in the inclined direction, which makes the flow of the slurry more complex and violent, and helps to better separate the minerals and sediment in the slurry. The U-shaped trough 2, as a preliminary treatment equipment, can effectively improve the desludging effect.

[0039] In this embodiment, Figure 2 and Figure 3 As shown, two groups of stirring members 5 are provided, and the shaft head at one end of the roller body 501 passes through the axis of the first driving gear 6 at the corresponding end thereof and forms an integral connection therewith, and the stirring members 5 form a relative rotational motion through the first driving gear 6, and at the same time, the blade groups 502 corresponding to the surfaces of the stirring members 5 that are in relative motion are distributed in an alternating structural form; the relative rotational motion of the two groups of stirring members 5 makes the stirring direction multi-dimensional, so that the slurry can be subjected to stirring force in all directions in the U-shaped trough 2, so that the minerals and sediment in the slurry can be stirred more fully, and through more intense stirring, the fine-grained sediment in the slurry can be more effectively stripped from the surface of the mineral particles, so that the separation of sediment and minerals is finer, the quality of desludging is improved, and the mixing speed of the slurry and the added agents (such as flocculants, dispersants, etc.) can be accelerated to play their role faster, thereby improving the efficiency of the entire desludging process.

[0040] In this embodiment, Figure 3 As shown, the outer wall of the mud trough 503 is provided with grid holes, and the interior of the mud trough 503 presents a cavity, and the fan-shaped panel 504 is located at the lower end of the stirring member 5, and the fan-shaped panel 504 forms an opening and closing structure at one end of the mud trough 503, and the fan-shaped panel 504 is located at the upper end and is threadedly connected to the mud trough 503 through a quick-release bolt; when the stirring member 5 is rotating, the large particles of mud and sand peeled off will be embedded in the interior through the grid holes on the surface of the mud trough 503 due to its soft characteristics. Since the large particles of mud and sand have a certain motion trajectory and inertia in the stirring flow field, the grid holes provide a special collection path for these mud and sand, which are effectively separated from the ore particles, avoiding the large particles of mud and sand from being mixed into the slurry again, and improving the efficiency and accuracy of mud removal. When it is necessary to clean the mud and sand in the mud trough 503, the operator can easily disassemble the fan-shaped panel 504 to remove the accumulated mud and sand, thereby solving the problem of difficult mud and sand cleaning in traditional equipment and reducing the risk of equipment failure and secondary pollution caused by residual mud and sand.

[0041] In this embodiment, Figure 4 As shown, the screen plate 7 is distributed inside the main body 1 in an inclined shape, and the sliding block surface of the screen plate 7 is fixedly connected with a spring, and one end of the spring is fixed in a slide groove corresponding to the inner wall of the main body 1, and the screen plate 7 reciprocates through the cam 9 below it through the spring, and the cam 9 is respectively distributed at the highest end and the lowest end of the bottom of the screen plate 7; the ore and ore slurry preliminarily processed by the U-shaped groove 2 will all flow into the main body 1, and the large particles of ore will be intercepted by the aperture of the screen plate 7 and remain on the screen plate 7, and move in a specific direction under the combined action of inclination and vibration, while the slurry, gravel and Small ores can flow downward through the sieve holes smoothly, achieving preliminary separation of materials of different particle sizes and improving screening efficiency. The sieve plate 7 reciprocates up and down under the action of the elastic reset structure composed of the cam 9 and the spring to prevent the sieve holes from being blocked. For some particles with particle sizes close to the size of the sieve holes, the vibration can enable them to continuously adjust their positions, which is more conducive to passing through the sieve holes. At the same time, the vibration can also make the material more evenly distributed on the sieve plate 7, avoiding the accumulation of materials in local areas that affect the screening effect, further improving the separation ability of ores and sediments of different particle sizes, and allowing them to be transported to the surface of the separation belt 10 at a uniform speed and flow rate.

[0042] In this embodiment, Figure 4 As shown, the main body 1 forms an upper and lower cavity through the screen plate 7, and the cam 9 and the precipitation frame 12 are located in the lower cavity, the nozzle 8 is located in the upper cavity, and the precipitation frame 12 is slidably connected to the lower cavity through the support rod 1201, and at the same time, a semi-enclosed baffle is arranged in the area of ​​the main body 1 corresponding to the lower cavity and on the same side as the pulley 13, the pulley 13 is distributed up and down, and the pull rope 14 is inserted and slidably connected to the slit on the inner wall of the pulley 13, and a metal column for winding the pull rope 14 is fixedly connected to the position of the outer wall of the main body 1 corresponding to the pulley 13; when the screen plate 7 moves, the nozzle 8 washes the vibrating ore on the screen plate 7, which can effectively remove impurities such as mud and sand attached to the surface of the ore, The secondary separation is realized, and with the assistance of vibration, it is more comprehensive and thorough, and the sewage, mud and small ore mixed slurry produced by the clear washing falls into the lower cavity. Through the pipeline connected to the lower cavity and the hydrocyclone 4, these materials can be smoothly transferred to the hydrocyclone 4 for further separation treatment. The hydrocyclone 4 uses the principle of centrifugal force to more accurately separate materials of different densities and particle sizes. The small ore with larger density will move on the inner wall of the hydrocyclone 4 and be discharged from the bottom flow port. The bottom of the main body 1 is a semi-closed structure, so that the ore can be maintained in a relatively sealed cavity when the preliminary particle size screening is realized, reducing the splashing of the slurry.

[0043] In this embodiment, Figure 5As shown, the sedimentation rack 12 has edges on all four sides and a sloped structure inside, and the movable plate 1202 is located at a low point of the sedimentation rack 12; as the bottom structure in the main body 1, the sedimentation rack 12 will inevitably have a small amount of residual mud and sand accumulated on the surface, and the sedimentation rack 12 can be lifted by pulling the pull rope 14, making the cleaning work convenient, and the sloped structure inside the sedimentation rack 12 provides a natural gathering direction for the settled mud and sand, so that the mud and sand gradually gather along the slope to the low point where the movable plate 1202 is located, and the movable plate 1202 is located at a low point of the sedimentation rack 12. After lifting the sedimentation rack 12, the movable plate 1202 can be opened, so that the mud and sand settled in the sedimentation rack 12 can be completely discharged, and thorough cleaning is achieved. Compared with the traditional fixed structure, the cleanliness of the sedimentation rack 12 after each cleaning is guaranteed, which helps to maintain the stable operation of the equipment and improve the operating stability and reliability of the entire desludging device.

[0044] In this embodiment, Figure 4 and Figure 6 As shown, the separation belt 10 is located below the end where the endpoint of the screen plate 7 is low, and the separation belt 10, the upper belt 15 and the lower mesh belt 16 are all rotatably connected to a number of support rollers distributed at equal distances, and the support rollers at both ends of the separation belt 10 are integrally connected to the synchronous wheels in the synchronous belt 11 through shafts, and at the same time, the upper belt 15 and the lower mesh belt 16 are rotatably connected to pulleys 17; the separation belt 10 is located below the end where the endpoint of the screen plate 7 is low, and can receive the large ores screened and slipped down from the screen plate 7, thereby realizing seamless connection of materials between different processing links. Since the separation belt 10, the upper belt 15 and the lower mesh belt 16 are all provided with support roller structures, they can withstand a certain material weight and pressure, and can still maintain a good operating state when facing ores and muds of different particle sizes and viscosities.

[0045] In this embodiment, Figure 6 and Figure 7 As shown, the second driving gear 18 is coaxially connected to the pulley 17 at the corresponding end thereof, and relative motion is formed between the upper belt 15 and the lower belt 16, and there is a gap between the upper belt 15 and the lower belt 16, and a microporous structure is distributed on the surface of the lower belt 16; when the material and slurry treated by the hydrocyclone 4 enter between the upper belt 15 and the lower belt 16, an extrusion effect is formed through their relative motion, and this extrusion can effectively squeeze out the liquid in the solid material, so that the liquid flows into the cavity of the diversion box 3 through the microporous structure on the surface of the lower belt 16, while the solid material is trapped on the surface of the lower belt 16, and after being extruded into blocks, it flows out with the transmission of the lower belt 16, ensuring that materials in different phases are separated and processed in an expected manner, thereby improving the convenience and environmental protection of subsequent processing.

[0046] In this embodiment, Figure 6 and Figure 7 As shown, the drainage groove 20 is L-shaped and forms an independent cavity, and the drainage groove 20 is horizontal and fits the surface of the lower mesh belt 16, and a plurality of inclined water holes are arranged in the horizontal area and form a through surface with the inner cavity of the drainage groove 20, and the guide plate 19 is distributed at 45 degrees, and the end with the higher end point is an arc surface and fits the corner of the lower mesh belt 16, and an independent cavity is formed in the diverter box 3 through the lower mesh belt 16, and a drainage port is arranged on one side of the outer wall of the diverter box 3 corresponding to the area of ​​the cavity; the material after being treated by the hydrocyclone 4 The substance and slurry are transported to the drainage trough 20 through the centrifugal pump and pipeline. The structure and shape of the drainage trough 20 are helpful to effectively guide the substance and slurry transported from the hydrocyclone 4, ensure the flow direction of the substance to be treated, complete the solid-liquid separation, and the medium entering the independent cavity in the diversion box 3 through the microporous structure of the lower mesh belt 16 can be processed through the drainage port and the external pipeline, which helps to maintain the continuity of the entire desludging process, so that each link can cooperate closely, and improve the working efficiency and stability of the entire device.

[0047] In summary, the desludging device for mining and mineral processing, when in use, uses an external conveying device to convey the slurry to the inside of the U-shaped trough 2, wherein the first driving gear 6 on one side is driven to rotate by a servo motor, thereby rotating the other group of first driving gears 6 meshing therewith, and the two groups of stirring members 5 inside the U-shaped trough 2 rotate relatively, and under the relative rotational movement, the slurry is subjected to a multi-dimensional stirring force in the U-shaped trough 2, which makes the minerals and mud and sand be fully stirred, and the fine-grained mud and sand are effectively stripped from the surface of the mineral particles, and at the same time accelerates the mixing of the slurry and the additives (such as flocculants, dispersants, etc.), and in the stirring process, the large-grained mud and sand are embedded in the internal cavity of the mud trough 503 through the grid holes on the outer wall thereof due to their relatively soft characteristics, and due to the inclined distribution of the U-shaped trough 2, the large-grained mud and sand are embedded in the internal cavity of the mud trough 503 through the grid holes on the outer wall thereof. 2 The ore and ore pulp after preliminary processing are all collected into the main body 1 through the slot and fall on the surface of the screen plate 7. The slurry will directly flow into the area where the sedimentation rack 12 is located at the bottom through the through hole. At the same time, the screen plate 7 will intercept the mineral raw materials. The two groups of cam 9 components rotate synchronously through the synchronous belt 11. The cam 9 contacts the upper screen plate 7 when rotating, and the screen plate 7 reciprocates up and down under the action of the spring. The large particles of ore are intercepted by the aperture of the screen plate 7 and remain on the screen plate 7. Under the combined action of inclination and vibration, they move in a specific direction, while the slurry, gravel and small ore fall downward into the lower cavity of the main body 1 through the screen hole to achieve preliminary screening. The large particles of ore on the surface of the screen plate 7 will be transported to the surface of the separation belt 10 at a uniform speed and flow rate. At the same time, when When the sieve plate 7 is moving, the nozzle 8 is connected to the external water supply equipment through a pipeline to wash the vibrating ore on the sieve plate 7. The washing can more comprehensively and thoroughly remove impurities such as mud and sand attached to the surface of the ore to achieve secondary separation. At the same time, the centrifugal pump on one side of the diversion box 3 will drive the mixed slurry containing mud and small ores in the lower cavity of the main body 1 into the hydrocyclone 4 (ZC-300) from the lower cavity of the main body 1. The hydrocyclone 4 uses the principle of centrifugal force to more accurately separate materials of different densities and particle sizes. Small ores with larger density move on the inner wall of the hydrocyclone 4 and are discharged from the bottom flow port, while particles and liquids with smaller density are discharged from the overflow port and transported to the inside of the drainage trough 20 through the pipeline and the centrifugal pump. At the same time, the water at the front end of the drainage trough 20 The drainage holes arranged at the horizontal position merge into the space between the upper belt 15 and the lower belt 16. There is a gap between the upper belt 15 and the lower belt 16, and they are driven by a pulley 17 and a second driving gear 18 coaxially connected to the pulley 17, respectively, to form a relative motion. When the material and slurry enter between the two, the relative motion produces an extrusion effect, which squeezes out the liquid in the solid material. The liquid passes through the microporous structure of the lower belt 16 and merges into the cavity in the diversion box 3. The solid material is trapped on the surface of the lower belt 16, and after being extruded into blocks, it is driven by the lower belt 16 and discharged from the guide plate 19, thereby completing the entire ore dressing and washing process.
