Description

Technical Field

[0001] The invention relates to the field of ore washing equipment, in particular to an ore washing machine for ore dressing. Background Art

[0002] After the ore is mined, it needs to be cleaned before crushing and screening to eliminate the dust, soil and other debris on the surface of the ore that may affect subsequent operations. Ore washing equipment is also divided into drum type and spiral type. Among them, the drum type ore washer is suitable for the cleaning process of ores with larger diameters. It mainly places the ore in a rotating drum and washes the ore through the mutual friction between the ores and the water flow.

[0003] Related technologies can refer to the Chinese patent with publication number CN114700307A, which discloses a water-saving ore washing device and ore washing method, including an ore washing mechanism and a circulating water supply mechanism, the ore washing mechanism includes rollers, a ore washing cylinder is rotatably arranged on the rollers, a spiral blade is arranged on the inner wall of the ore washing cylinder, the ore washing cylinder is divided into a rough washing section, a water discharge section and a fine washing section in sequence, the water discharge section is a grating ring connecting the rough washing section and the fine washing section, the lower part of the water discharge section is connected to the circulating water supply mechanism, a rough washing water pipe and a fine washing water pipe are respectively inserted in the rough washing section and the fine washing section, the rough washing water pipe and the fine washing water pipe are both connected to the circulating water supply mechanism, a plurality of spray pipes are arranged in the middle and lower part of the rough washing water pipe, and a plurality of nozzles are arranged in the middle and lower part of the fine washing water pipe. The device has the advantage of saving water resources.

[0004] With regard to the above-mentioned related technologies, during the ore cleaning process, after the ore raw materials are added into the ore washing drum, as the ore washing drum rotates, the ore will rotate with the ore washing drum, and will be cleaned in cooperation with the water flow sprayed from the coarse washing water pipe and the fine washing water pipe. However, when it is necessary to increase the cleaning speed of the ore and increase the rotation speed of the ore washing drum, the ore is easily moved to the top of the fine washing water pipe or the coarse washing water pipe under the action of centrifugal force and the push of the spiral blades, and falls to the fine washing water pipe or the coarse washing water pipe under the action of gravity, so that a small amount of ore is accumulated and stays above the water pipe under the adhesion of the soil, resulting in a waste of ore raw materials and increasing the load of the water pipe. Therefore, it is necessary to regularly clean the ore raw materials accumulated above the water pipe, and it is inconvenient to clean the water pipe when the ore washing drum continues to rotate. Summary of the invention

[0005] In order to facilitate the cleaning of deposits above the water pipe during the ore washing process, the present application provides an ore washing machine for mineral processing.

[0006] The present application provides an ore washing machine for mineral processing, which adopts the following technical solution:

[0007] An ore washing machine for mineral processing comprises a base and an ore washing barrel, wherein the ore washing barrel is located at the upper end of the base and is connected to the base in a rolling manner in the transverse direction, a plurality of spiral push plates are arranged on the inner wall of the ore washing barrel in a circumferential direction, a driving member for driving the ore washing barrel to roll is arranged on the base, a water pipe is arranged in the ore washing barrel, the water pipe is connected to a water supply system, the water pipe passes through the ore washing barrel and is located at the upper end of the ore washing barrel, a plurality of drainage ports are opened at the lower end of the water pipe in the length direction, a plurality of blocking pipes are arranged on the outer side of the water pipe, all the blocking pipes are connected to the water pipe in a coaxial rotation manner, a power member for driving the blocking pipe to rotate is arranged on the base, the drainage port is located between two adjacent blocking pipes, the blocking pipe avoids the drainage port, and a fixed device is arranged between the adjacent blocking pipes. A connecting plate is provided, and a side of the connecting plate close to the axis of the blocking pipe is fitted with the outer side of the water pipe. The connecting plate is slidably connected with a cleaning plate in the direction close to or away from the axis of the blocking pipe. The side of the cleaning plate close to the water pipe contacts the water pipe. An elastic member is provided between the cleaning plate and the connecting plate, and the elastic member is used to drive the cleaning plate close to the water pipe. An arc plate is provided at the lower end of the water pipe, and the axis of the arc plate is parallel to the axis of the water pipe. The connecting plate is provided with a avoidance opening matched with the arc plate, and a drainage hole is provided on the arc plate in the direction pointing to the outer circle along the axis of the water pipe. The cleaning plate is provided with a cleaning hole matched with the drainage hole, and one end of the cleaning hole is located at the end face of the cleaning plate close to the water pipe, and the other end is located at the end face of the cleaning plate along the axis of the blocking pipe.

[0008] By adopting the above technical solution, after the ore is added to the ore washing barrel, under the support of the base, when the driving part drives the ore washing barrel to rotate, the ore washing barrel drives the ore to move along the axis of the ore washing barrel through the spiral push plate. In the initial state, the arc plate is at the lower end of the water pipe. After the water in the water supply system enters the water pipe, it enters the drainage hole of the arc plate along the drainage port, and is discharged to the ore along the drainage hole to clean the ore. The cleaned ore is discharged from the other end of the ore washing barrel. During the ore washing process, if some ore raw materials move to the top of the ore washing barrel under the action of centrifugal force and the spiral push plate, and fall into the water pipe under the action of gravity, the blocking pipe protects the water pipe and slows down the impact of the ore on the water pipe. At this time, the cleaning plate conflicts with the water pipe under the action of the elastic member, and the cleaning plate is in a storage state. When ore and soil are accumulated above the barrier pipe, the barrier pipe near the end of the water pipe is driven to rotate by the power part. Under the action of the connecting plate, all the barrier pipes rotate synchronously. When the barrier pipe rotates, the ore and soil pushed above it move downward and are separated from the barrier pipe under the action of gravity. When the barrier pipe rotates, it drives the cleaning plate to approach the arc plate. When the arc plate passes through the avoidance port and collides with the cleaning plate, it pushes the cleaning plate away from the water pipe. When one end of the cleaning hole is connected with the drainage hole, the water in the water pipe enters the cleaning hole along the drainage hole and is discharged from the other end of the cleaning hole to the outer edge of the barrier pipe, thereby cleaning the barrier pipe, thereby reducing the probability of soil adhering to the outside of the barrier pipe. It is more convenient to clean the deposits above the water pipe during the ore washing process.

[0009] Optionally, the power component includes a support block, sprocket one, sprocket two, a chain and a driving motor. The support block is located at the upper end of the base and is fixedly connected to the base. The blocking tube located at the end of the water pipe is rotatably connected to the support block. A set of sprockets is arranged on the outside of the blocking tube close to the support block and is coaxially fixed with the corresponding blocking tube. Sprocket two is rotatably connected to the support block. The chain is engaged between sprocket one and sprocket two. The driving motor is fixedly connected to the support block for driving sprocket two to rotate.

[0010] By adopting the above technical solution, the driving motor drives the sprocket two to rotate when working. Under the transmission action of the chain, the rotation of the sprocket two drives the sprocket one to rotate, and then drives the blocking tube to rotate, thereby realizing the cleaning of the blocking tube.

[0011] Optionally, the lower end of the support block is rotatably connected to a cleaning roller, which extends into the ore washing cylinder and is arranged parallel to the water pipe. The cleaning roller is located at the outer circle of the barrier tube and is on one side of the barrier tube in the horizontal direction. The cleaning roller is fixed with a scraper along the length direction, and a torsion spring is arranged between the cleaning roller and the support block. The torsion spring applies thrust to the cleaning roller so that the scraper fits against the outer circle of the barrier tube.

[0012] By adopting the above technical solution, under the action of the torsion spring, the cleaning roller drives the scraper to fit the outer edge of the barrier tube, and then when the barrier tube rotates, the scraper cleans the barrier tube, which is beneficial to further improve the cleaning effect of the barrier tube.

[0013] Optionally, the drain outlet is arc-shaped, and a connecting pipe is fixedly provided on the side of the arc plate close to the axis of the water pipe. The connecting pipe is hollow and connected to the drain hole. A sealing plate is fixedly provided on the end of the connecting pipe away from the arc plate. The sealing plate is located on the inner side of the water pipe and fits against the inner wall of the water pipe. The water pipe is provided with a rotating part for driving the connecting pipe to rotate around its own axis.

[0014] By adopting the above technical solution, the sealing plate and the connecting pipe cooperate to seal the drain outlet, so that the water in the water pipe flows along the connecting pipe to the drain hole. When the connecting pipe is driven to move by the rotating part, the connecting pipe drives the arc plate to rotate along the circumference of the water pipe, thereby facilitating the adjustment of the drainage direction of the water pipe.

[0015] Optionally, the rotating part includes a rotating handle, a worm gear and a housing, a rotating rod is arranged along the axis line in the water pipe, the rotating rod rotates coaxially with the water pipe, all sealing plates are fixedly connected to the rotating rod, a vertical tube is fixedly provided at one end of the water pipe along the length direction, the rotating rod passes through the vertical tube and is rotatably connected to the vertical tube, the housing is fixed on the side of the vertical tube away from the water pipe, the end of the rotating rod passes through the vertical tube, is located in the housing and is coaxially fixed with the worm gear, the rotating handle passes through the housing and is rotatably connected to the housing, and the rotating handle is fixedly connected to a worm meshing with the worm gear.

[0016] By adopting the above technical solution, the box supports the rotating handle. When the rotating handle rotates, the worm gear is driven to rotate through the worm. Under the support of the vertical tube, the worm gear drives the rotating rod to rotate, and then the rotating rod drives all the sealing plates to rotate, so as to realize the adjustment of the arc plate.

[0017] Optionally, a blocking plate parallel to the water pipe is provided in the ore washing barrel, and the blocking plate is located close to the inner wall of the ore washing barrel. When the ore washing barrel rotates, the spiral push plate is driven to approach the blocking plate. The base is provided with a mounting frame for supporting the blocking plate. A plurality of interception plates are provided along the length direction on the side of the blocking plate away from the axis of the ore washing barrel. The interception plates are made of elastic material, and the interception plates extend in a direction away from the blocking plates in a natural state, and extend into the gap between the spiral push plate and the inner wall of the ore washing barrel.

[0018] By adopting the above technical solution, the bottom plate supports the blocking plate through the mounting frame. When ore, soil and other impurities move upward with the rotation of the ore washing tube, they are intercepted by the blocking plate, and the blocking plate extends into the gap of the spiral push plate. When the spiral push plate collides with the blocking plate, the blocking plate deforms and avoids the collision under the action of the spiral push plate. The blocking plate limits the moving range of ore and soil, which helps to slow down the accumulation speed of ore and soil above the blocking pipe.

[0019] Optionally, the mounting frame is bent along the circumference of the ore washing cylinder, and the mounting frame is slidably connected to a mounting seat along the length direction, a rotating shaft is fixed to the end of the blocking plate along the length direction, the rotating shaft passes through the mounting seat and is rotatably connected to the mounting seat, the mounting seat is provided with a positioning clamp for fixing the rotating shaft, the mounting seat is provided with a fixing bolt, and the mounting frame is provided with a plurality of threaded holes along the length direction, the fixing bolt passes through the mounting seat and is threadedly connected to any threaded hole.

[0020] By adopting the above technical solution, with the cooperation of the fixing bolts and the threaded holes, the mounting frame fixes and supports the mounting seat, the mounting seat supports the blocking plate through the rotating shaft, and limits the rotation of the rotating shaft through the positioning clamp. When the rotating shaft rotates, it drives the blocking plate to rotate, thereby facilitating the adjustment of the angle of the blocking plate during positioning.

[0021] Optionally, one end of the ore washing barrel along the length direction is set as a drain part. When the ore washing barrel is working, the ore moves toward the drain part in the ore washing barrel, and the spiral push plate extends toward the drain part along the axis of the ore washing barrel. The drain part is provided with a plurality of drain holes along the circumferential direction. A collecting box is fixedly provided at the upper end of the base. The collecting box is located directly below the drain part and fits with the outer circle of the drain part.

[0022] By adopting the above technical solution, the cleaned ore moves to the drain part under the action of the spiral push plate. At this time, the water used to clean the ore is discharged from the drain hole and falls into the collection box under the action of gravity, which is convenient for recycling.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After adding the ore into the washing barrel, under the support of the base, when the driving part drives the washing barrel to rotate, the washing barrel drives the ore to move along the axis of the washing barrel through the spiral push plate. In the initial state, the arc plate is at the lower end of the water pipe. After the water in the water supply system enters the water pipe, it enters the drainage hole of the arc plate along the drainage port, and is discharged to the ore along the drainage hole to clean the ore. The cleaned ore is discharged from the other end of the washing barrel. During the washing process, if some ore raw materials move to the top of the washing barrel under the action of centrifugal force and the spiral push plate, and fall into the water pipe under the action of gravity, the blocking pipe protects the water pipe and slows down the impact of the ore on the water pipe. At this time, the cleaning plate conflicts with the water pipe under the action of the elastic member, and the cleaning plate is in a storage state. When ore and soil are accumulated on the top of the blocking pipe, the blocking pipe near the end of the water pipe is driven to rotate by the power part. Under the action of the connecting plate, all the blocking pipes rotate synchronously. When the blocking pipe rotates, the ore and soil pushed on the top move downward and are separated from the blocking pipe under the action of gravity. When the blocking pipe rotates, it drives the cleaning plate to approach the arc plate. When the arc plate passes through the avoidance port and collides with the cleaning plate, it pushes the cleaning plate away from the water pipe. When one end of the cleaning hole is connected with the drainage hole, the water in the water pipe enters the cleaning hole along the drainage hole and is discharged from the other end of the cleaning hole to the outer edge of the blocking pipe, thereby cleaning the blocking pipe, thereby reducing the probability of soil adhering to the outside of the blocking pipe. It is more convenient to clean the deposits above the water pipe during the ore washing process.

[0025] 2. The bottom plate supports the blocking plate through the mounting frame. When ore, soil and other impurities move upward with the rotation of the ore washing tube, they are intercepted by the blocking plate, and the blocking plate extends into the gap of the spiral push plate. When the spiral push plate collides with the blocking plate, the blocking plate deforms and avoids it under the action of the spiral push plate. The blocking plate limits the moving range of ore and soil, which helps to slow down the accumulation speed of ore and soil above the blocking pipe. BRIEF DESCRIPTION OF THE DRAWINGS

When the ore-washing barrel 2 rotates, it drives the spiral push plate 21 to move.

[0038] Reference Figure 2 and Figure 3 One end of the ore-washing barrel 2 is set as the feed end. During the ore-washing process, the ore is transported into the ore-washing barrel 2 along the feed end. During the rotation of the ore-washing barrel 2, the ore raw material is driven to move along the axis direction of the ore-washing barrel 2 by the spiral push plate 21. A water pipe 3 is arranged in the ore-washing barrel 2. The water pipe 3 is located at the upper end of the ore-washing barrel 2, and the water pipe 3 is parallel to the axis of the ore-washing barrel 2.

[0039] Reference Figure 2 and Figure 4 The water pipe 3 is connected to a water supply system. When the water supply system is working, water is delivered to the water pipe 3.

When the rotating handle 51 rotates, the worm gear 52 is driven to rotate through the worm 511, and then all the sealing plates 34 are driven to move through the worm gear 52. When the sealing plates 34 move, the connecting pipes 33 and the arc plates 32 are driven to move, so as to adjust the direction of the drain hole 321. Further, in other embodiments, the rotating rod 35 can also be directly driven to rotate by a motor or other driving mechanism.

[0043] Reference Figure 2 and Figure 6 A material blocking plate parallel to the water pipe 3 is also provided in the ore washing cylinder 2. The base 1 is provided with two mounting frames 14 for supporting the material blocking plate. The two mounting frames 14 are respectively located at both ends of the ore washing cylinder 2 along the length direction. The mounting frames 14 are semi-annular, and the mounting frames 14 are located at the upper end of the ore washing cylinder 2 and are coaxial with the ore washing cylinder 2. A support column is fixedly provided at the upper end of the base 1, and the support column is fixedly connected to the mounting frame 14. The base 1 supports the mounting frame 14 through the support column.

[0044] Reference Figure 2 and Figure 6The blocking plate 6 is located between the two mounting frames 14. The mounting frame 14 is provided with a mounting seat 15. The mounting seat 15 is slidably connected with the mounting frame 14 along the length direction of the mounting frame 14. The mounting seat 15 is provided with a fixing bolt 151. The mounting frame 14 is provided with a plurality of threaded holes 141 adapted to the fixing bolt 151 along the length direction. The fixing bolt 151 passes through the mounting seat 15 and is threadedly connected with any threaded hole 141. The fixing bolt 151 cooperates with the mounting frame 14 to support the mounting seat 15. When the fixing bolt 151 is threadedly connected with different threaded holes 141, the mounting seat 15 is installed at different positions, thereby facilitating the adjustment of the position of the mounting seat 15.

[0045] Reference Figure 2 and Figure 6 , both ends of the blocking plate 6 along the length direction are fixed with a rotating shaft 62, the rotating shaft 62 is inserted into the mounting seat 15 and is rotatably connected to the mounting seat 15, the mounting seat 15 is provided with a positioning clamp, the positioning clamp includes a fixing block 161 and a positioning bolt 162, the fixing block 161 can be one, two or three. In this embodiment, two fixing blocks 161 are set, and the two fixing blocks 161 are respectively located on both sides of the rotating shaft 62. The fixing seat is provided with a mounting groove for placing the fixing block 161, and the fixing block 161 is located in the mounting groove and fits with the inner wall of the mounting groove. The rotating shaft 62 is provided with a plurality of positioning grooves 621 along the circumferential direction, and the positioning grooves 621 are arranged along the axial direction of the rotating shaft 62. The fixing block 161 is provided with positioning teeth 163 adapted to the positioning grooves 621. The positioning teeth 163 are inserted into the positioning grooves 621 and fit with the inner wall of the positioning grooves 621. The fixing block 161 limits the rotation of the rotating shaft 62 through the cooperation between the positioning teeth 163 and the positioning grooves 621, and then positions the blocking plate 6 through the rotating shaft 62. The positioning bolts 162 correspond to the fixing blocks 161 one by one, and the positioning bolts 162 pass through the fixing blocks 161 and are threadedly connected to the mounting seat 15, thereby positioning the fixing blocks 161.

[0046] Reference Figure 2 and Figure 6 The blocking plate 6 is located near the inner wall of the ore-washing barrel 2. When the ore-washing barrel 2 rotates, the centrifugal force and the spiral push plate 21 drive the ore, soil and other materials to approach the blocking plate 6. The blocking plate 6 and the spiral push plate 21 do not interfere with each other. When the ore and soil collide with the blocking plate 6, the blocking plate 6 blocks them, thereby reducing the probability of the ore and soil moving to the top of the ore-washing barrel 2. A plurality of interception plates 61 are fixedly arranged on one side of the blocking plate 6 close to the inner wall of the ore-washing barrel 2. The interception plates 61 are evenly arranged along the length direction of the blocking plate 6, and the interception plates 61 extend to the gaps of the spiral push plate 21 along the circumferential direction.

[0047] Reference Figure 2 and Figure 6The interception plate 61 is made of elastic material, such as rubber. When the spiral push plate 21 contacts the interception plate 61, the interception plate 61 is pushed to deform and avoid the spiral push plate 21. The interception plate 61 is conducive to improving the blocking effect of the blocking plate 6, and further reducing the probability of ore and soil moving to the top of the ore washing cylinder 2. By adjusting the rotating shaft 62, the blocking plate 6 is in an inclined state, reducing the probability of ore and soil that pass over the interception plate 61 falling and accumulating and staying above the blocking plate 6.

[0048] Reference Figure 1 and Figure 2 The end of the washing cylinder 2 away from the feed end is set as a drain portion 22, and the drain portion 22 is provided with a plurality of drain holes 221 along the circumferential direction, and the muddy water mixed with the ore is discharged from the drain holes 221. A collecting box 17 is installed at the upper end of the base 1, and the collecting box 17 is located below the drain portion 22 and contacts the outer edge of the drain portion 22. The muddy water passing through the drain holes 221 enters the collecting box 17, which is convenient for recycling and processing.

[0049] Reference Figure 2 and Figure 4 A plurality of blocking tubes 4 are sleeved on the outside of the water pipe 3. The blocking tubes 4 are coaxially connected to the water pipe 3 for rotation. The blocking tubes 4 are spaced apart from the arc plate 32. A connecting plate 41 is fixedly connected between adjacent blocking tubes 4. When any blocking tube 4 rotates, the other blocking tubes 4 are driven to rotate through the connecting plate 41. The connecting plate 41 is provided with an avoidance opening 411 corresponding to the arc plate 32. When the blocking tube 4 rotates, the connecting plate 41 avoids the arc plate 32 through the avoidance opening 411.

[0050] Reference Figure 2 and Figure 4 The connecting plate 41 is provided with a sliding groove connected to the avoidance opening 411, and a cleaning plate 42 is provided in the sliding groove. The cleaning plate 42 is slidably connected to the connecting plate 41 in a direction close to or away from the axis of the water pipe 3. The connecting plate 41 limits the cleaning plate 42 through the sliding groove, so that the cleaning plate 42 is driven to move when the connecting plate 41 moves. An elastic member 43 is provided between the cleaning plate 42 and the connecting plate 41. The elastic member 43 is a spring, one end of the spring is fixedly connected to the cleaning plate 42, and the other end is fixedly connected to the connecting plate 41. When the elastic member 43 is in a natural state, one end of the cleaning plate 42 close to the water pipe 3 contacts the water pipe 3, and the other end is flush with the end surface of the connecting plate 41 away from the water pipe 3.

[0051] Reference Figure 2 and Figure 4The cleaning plate 42 is provided with a cleaning hole 421, one end of which is located at the end surface of the cleaning plate 42 close to the water pipe 3, and the other end is located at the end surface of the cleaning plate 42 along the axial direction of the water pipe 3. The blocking pipe 4 covers and protects the water pipe 3. When part of the ore and soil passes over the blocking plate 6 and the intercepting plate 61 and moves to the top of the washing cylinder 2 and falls to the water pipe 3 under the action of gravity, the blocking pipe 4 intercepts them, reducing the probability of the ore hitting and damaging the water pipe 3.

[0052] Reference Figure 1 and Figure 2 The base 1 is provided with a power member 12 for driving the blocking pipe 4 to rotate. When the blocking pipe 4 needs to be cleaned, the blocking pipe 4 rotates to drive the ore and soil accumulated on the blocking pipe 4 to move, so that they are gradually separated from the blocking pipe 4 under the action of gravity. Initially, the connecting plate 41 is above the water pipe 3. When cleaning the blocking pipe 4, the blocking pipe 4 drives the connecting plate 41 and the cleaning plate 42 to move toward the arc plate 32. After the cleaning plate 42 contacts the arc plate 32, it moves along the arc plate 32 in a direction away from the water pipe 3. At this time, the elastic member 43 gradually deforms, so that the end of the cleaning plate 42 away from the water pipe 3 extends out of the sliding groove, so that the end of the cleaning hole 421 faces the outer edge of the blocking pipe 4. When the cleaning hole 421 is directly opposite to the drain hole 321, water flows from the drain hole 321 into the cleaning hole 421, and sprays toward the outer edge of the blocking pipe 4 along the cleaning hole 421, thereby cleaning the blocking pipe 4 and improving the cleaning effect of the blocking pipe 4.

[0053] Reference Figure 4 and Figure 5 The power member 12 includes a support block 121, a sprocket wheel 122, a sprocket wheel 123, a chain 124 and a driving motor 125. The support block 121 is located at the end of the ore-washing barrel 2, and the support block 121 is fixed to the side of the mounting frame 14 away from the ore-washing barrel 2. The water pipe 3 is located on the side of the support block 121 close to the base 1. The blocking pipe 4 at the end of the water pipe 3 passes through the support block 121 and is rotatably connected to the support block 121. The sprocket wheel 123 is located on the side of the support block 121 close to the ore-washing barrel 2 and is rotatably connected to the support block 121, and the sprocket wheel 122 is located outside the blocking pipe 4 and is coaxially fixed with the blocking pipe 4. The chain 124 is between the sprocket wheel 122 and the sprocket wheel 2 123, and the chain 124 is meshed with both the sprocket wheel 122 and the sprocket wheel 2 123. The driving motor 125 is fixed to the supporting block 121, and the output shaft of the driving motor 125 is connected to the sprocket 2 123. When the driving motor 125 is working, the sprocket 2 123 is driven to rotate. When the sprocket 2 123 rotates, the chain 124 drives the sprocket 1 122 to rotate, and then the sprocket 1 122 drives the blocking tube 4 to rotate.

[0054] Reference Figure 3 and Figure 4A cleaning roller 13 is provided at the lower end of the support block 121. The cleaning roller 13 is located below the water pipe 3 and on the side of the water pipe 3 away from the blocking plate 6. The cleaning roller 13 is arranged parallel to the water pipe 3 and passes through the ore washing cylinder 2. The cleaning roller 13 is rotatably connected to the support block 121 in the vertical direction. A torsion spring 131 is provided between the support block 121 and the cleaning roller 13. One end of the torsion spring 131 is fixedly connected to the support block 121, and the other end is fixedly connected to the cleaning roller 13. A scraper 132 is provided on the side of the cleaning roller 13 close to the blocking pipe 4. The scraper 132 is arranged along the length direction of the cleaning roller 13. The torsion spring 131 applies a thrust to the cleaning roller 13, so that the scraper 132 fits the outer circle of the blocking pipe 4. When the blocking pipe 4 rotates, the scraper 132 cleans the outer periphery of the blocking pipe 4, thereby making the scraper 132 clean the blocking pipe 4, further improving the cleaning effect of the blocking pipe 4.

[0055] The working principle of an ore washing machine for mineral processing in an embodiment of the present application is as follows: the movement of ore and soil is intercepted during the rotation of the washing tube 2 by the cooperation of the blocking plate 6 and the interception plate 61, thereby preliminarily reducing the probability of ore and soil moving above the washing tube 2. When a small amount of ore and soil moves to the top of the washing tube 2 and falls toward the water pipe 3 under the action of gravity, the blocking pipe 4 protects the water pipe 3, thereby reducing the probability of the ore hitting and damaging the water pipe 3 when falling. When there is a large amount of ore and soil accumulated above the blocking pipe 4, the blocking pipe 4 close to the support block 121 is driven to rotate by the driving motor 125. Under the connection of the connecting plate 41, when any blocking pipe 4 rotates, the remaining blocking pipes 4 are driven to rotate. When the barrier pipe 4 rotates, the soil and ore accumulated on it fall down under the action of gravity, and when the barrier pipe 4 rotates, the cleaning plate 42 is driven to move through the connecting plate 41. When the cleaning plate 42 contacts the arc plate 32, it gradually moves away from the water pipe 3. When the cleaning hole 421 is connected with the drainage hole 321, the water in the water pipe 3 enters the cleaning hole 421 along the drainage hole 321, and is sprayed toward the outer edge of the barrier pipe 4 along the cleaning hole 421, so that the water flow cleans the barrier pipe 4. During the cleaning of the barrier pipe 4, the ore washing cylinder 2 does not need to be stopped, which makes it convenient to clean the deposits above the water pipe 3 during the ore washing process.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
