Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a cleaning machine for ore processing. Background Art

[0002] Ore washing is an important part of ore processing, which aims to remove dirt, impurities and fine-grained gangue from the surface of the ore. This process is crucial to improving ore quality, avoiding blockage of mineral processing equipment and improving overall production efficiency. Ore washers are equipment used to perform ore washing operations. There are many types of ore washers, including drum washers, spiral washers and trough washers, which clean the ore through mechanical mixing, flushing and separation.

[0003] A Chinese patent application document with publication number CN113941544A discloses an environmentally friendly ore washer, which includes an ore washing mechanism, an automatic cleaning mechanism and a circulation mechanism. A first motor drives the ore washing shaft to rotate for ore washing. The cleaning parts arranged on the spiral blades and the multiple cleaning ports arranged on the ore washing shaft increase the cleaning efficiency and make the cleaning cleaner. The automatic cleaning mechanism is arranged to automatically clean the inner wall of the cylinder, and the cleaning rubber is used to effectively prevent the wear of the spiral blades and the cylinder due to the ore stuck between the spiral blades and the inner wall of the cylinder. The circulation mechanism is arranged to collect and filter the washed waste water and reuse it to prevent the water from being directly discharged to pollute the environment, thereby saving energy and protecting the environment.

[0004] However, the cleaning mode of the above-mentioned environmentally friendly ore washing machine in the prior art is relatively simple, and is only applicable to ores with a small mud content. The cleaning effect on ores with a large mud content is poor, and it is difficult to cope with the diversity of ore properties. Summary of the invention

[0005] The present invention provides a cleaning machine for ore processing, aiming to solve the problem that the environmentally friendly ore washing machine in the related art has a relatively single cleaning mode and is difficult to cope with the diversity of ore properties.

[0006] The present invention provides a cleaning machine for ore processing, which adopts the following technical solution:

[0007] A cleaning machine for ore processing, comprising a cylinder arranged on a frame, wherein the upper end of the cylinder is provided with a feeding port, the lower end of the cylinder is provided with a discharging port, and the cylinder is provided with: a roller, wherein a plurality of the rollers are spirally distributed in the cylinder around the central axis of the cylinder to guide the ore to move toward the discharging port, and a water gap is provided between two adjacent rollers to allow the sewage after cleaning to pass through; a plate brush and a cylinder brush, wherein the plate brush and the cylinder brush are staggeredly arranged on each roller along the axial direction of the roller to rotate with the roller around the axis of the roller The plate brush is dynamically used to clean the ore, the plate brush extends along the axial direction of the roller and is rotatably installed on the roller, so that the plate brush can be folded on the roller, a torsion spring is provided between the plate brush and the roller, and a one-way limiter for limiting the rotation of the plate brush is provided on the roller, so that the plate brush can be locked on the roller, thereby hindering the movement of the ore; a nozzle, a plurality of the nozzles are arranged on the inner wall of the cylinder to wash the ore; a driving assembly, the driving assembly is transmission-connected to each roller to drive each roller to rotate in the same direction.

[0008] By adopting the above technical scheme, a plurality of spirally distributed rollers are arranged in the cleaning machine for ore processing, and a staggered cylindrical brush and a plate brush are arranged on each roller; when the driving component controls each roller to rotate forward, the cleaning machine can enter the quick washing mode, and the locked state of the plate brush in the quick washing mode can guide the ore to fall quickly, the cleaning time is short, the cleaning force is small, and it is suitable for ores with small mud content; when the driving component controls each roller to rotate reversely, the cleaning machine can enter the strong washing mode, and the locked state of the plate brush in the strong washing mode can hinder the movement of the ore to provide continuous resistance and friction during the falling process of the ore, and insert the ore gap to clean the ore, the cleaning time is long, the cleaning force is large, and it is suitable for ores with large mud content; in this way, a more flexible cleaning mode is provided, which has strong adaptability to ores of different properties and can process various types of ores.

[0009] Furthermore, multiple plate brushes are distributed along the circumference of the roller, and mounting seats corresponding to each plate brush are fixed on the outer circumference of the roller. The mounting seats are respectively provided with the one-way limiter and the one-way rotation groove on both sides of the length direction of the plate brush, and the one-way rotation groove is used to allow the plate brush to be folded.

[0010] Furthermore, a rotating head is fixed to one end of the plate brush close to the rotating roller, a rotating shaft is passed through and fixed on the rotating head, the rotating shaft is rotatably installed in the mounting seat, the torsion spring is connected between the rotating head and the mounting seat, and the one-way limiter can abut against the side wall of the rotating head to limit the rotation of the plate brush.

[0011] Furthermore, a water collecting plate is fixed inside the cylinder, and the water collecting plate is distributed below the multiple rollers and spirally arranged synchronously with the multiple rollers. The interior of the water collecting plate is hollow to form a guide channel, and the upper surface of the water collecting plate is provided with multiple water holes.

[0012] The above technical solution is adopted to collect the sewage after cleaning and guide the sewage to be discharged, so that the sewage after cleaning is separated from the ore in time to ensure the cleaning effect.

[0013] Furthermore, the water collecting plate is inclined downward from outside the cylinder to inside the cylinder, and a plurality of the water collecting plates are distributed along the radial direction of the cylinder.

[0014] The above technical solution can help turn over the ore that falls between two adjacent rollers and change the position of the ore in the axial direction of the roller, thereby further enhancing the cleaning effect.

[0020] Furthermore, the bristles of the cylindrical brush are soft bristles, and the bristles of the plate brush are hard bristles.

[0021] By adopting the above technical solution, the combined use of soft bristles and hard bristles can provide different resistances during the movement of the ore, which will make the downward movement speed of the ore passing through the cylindrical brush and the plate brush different. The ore in the two areas moves relative to each other, which can increase the friction and collision between the ores, produce a scrubbing action, and more effectively remove impurities and clay on the surface of the ore.

[0022] The beneficial effects of a cleaning machine for ore processing provided by the present invention are as follows: the cleaning machine for ore processing is provided with a plurality of spirally distributed rollers, and each roller is provided with a staggeredly distributed cylindrical brush and a plate brush; when the driving component controls each roller to rotate forward, the cleaning machine can enter a quick washing mode, and the locked state of the plate brush in the quick washing mode can guide the ore to fall quickly, the cleaning time is short, the cleaning force is small, and it is suitable for ores with a small mud content; when the driving component controls each roller to rotate reversely, the cleaning machine can enter a strong washing mode, and the locked state of the plate brush in the strong washing mode can hinder the movement of the ore to provide continuous resistance and friction during the falling process of the ore, and insert into the gap between the ore to clean the ore, the cleaning time is long, the cleaning force is large, and it is suitable for ores with a large mud content; in this way, a more flexible cleaning mode is provided, which has strong adaptability to ores of different properties and can process various types of ores.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 6 As shown, an embodiment of the cleaning machine for ore processing of the present invention includes a frame 10, a cylinder 20, a roller 30, a cylinder brush 40, a plate brush 50, a nozzle 60, a water collecting plate 70, a center column 80, a driving assembly and a filter plate 90.

[0033] like Figure 1 and Figure 2 As shown, the cylinder 20 is fixed on the frame 10, and the frame 10 is used to support the cylinder 20. The cylinder 20 includes a feeding part 210, a cleaning part 220 and a discharging part 230 connected in sequence from top to bottom. The feeding part 210 is funnel-shaped, so that a feeding port 211 is formed at the upper end of the cylinder 20, which is used to feed the ore to be cleaned into the cylinder 20. The cleaning part 220 is cylindrical, and a cleaning area is formed in the cleaning part 220. The discharging part 230 is funnel-shaped, so that a discharging port 231 is formed at the lower end of the cylinder 20, which is used to discharge the cleaned ore. The setting of the funnel-shaped structure can guide the flow of materials, and facilitate the input, cleaning, collection and discharge of materials.

[0034] like Figures 1 to 5 As shown, a plurality of rollers 30 are spirally distributed in the cleaning section 220 around the central axis of the cylinder 20 to guide the ore to move toward the discharge port 231. There is a water gap between two adjacent rollers 30 to allow the washed sewage to pass through. Figure 5 In the direction shown in , the counterclockwise rotation of the roller 30 is positive rotation, and the clockwise rotation of the roller 30 is reverse rotation. When multiple rollers 30 rotate forward, the movement of the ore can be accelerated to enter the fast washing mode, with a shorter washing time and a smaller washing force, which is suitable for ores with a smaller mud content. When multiple rollers 30 rotate reversely, the movement of the ore can be slowed down to enter the strong washing mode, with a longer washing time and a larger washing force, which is suitable for ores with a larger mud content.

[0035] like Figures 2 to 5 As shown, the cylindrical brush 40 and the plate brush 50 are staggeredly arranged on each roller 30 along the axial direction of the roller 30 to clean the ore as the roller 30 rotates around the axis of the roller 30.

[0036] The cylindrical brush 40 is cylindrical, and the bristles of the cylindrical brush 40 are evenly fixed on the outer peripheral side of each rotating roller 30. The bristles of the cylindrical brush 40 are soft, such as nylon and rubber, and are used to clean the ore, and the resistance to the movement of the ore is small.

[0037] The plate brush 50 is plate-shaped and extends along the axial direction of the rotating roller 30. The bristles of the plate brush 50 are relatively hard, such as metal wires and abrasive wires, and are used to clean the ore, and can provide stronger friction to generate greater resistance to the movement of the ore, thereby hindering the movement of the ore and inserting into the gap between the ore to clean the ore.

[0038] It should be noted that since the bristles of the cylindrical brush 40 and the plate brush 50 produce different resistances to the movement of the ore, the downward movement speed of the ore passing through the cylindrical brush 40 and the plate brush 50 will be different. The ore in the two areas will move relative to each other, which can increase the friction and collision between the ores, produce a scrubbing action, and more effectively remove impurities and clay on the surface of the ore.

[0039] like Figures 4 to 6 As shown, two plate brushes 50 are distributed along the circumference of the roller 30. A mounting seat 510 corresponding to each plate brush 50 is fixed on the outer peripheral side of the roller 30, and the mounting seat 510 is respectively provided with a one-way limiter 511 and a one-way rotation groove 512 on both sides of the length direction of the plate brush 50. The one-way limiter 511 is used to limit the rotation of the plate brush 50 so that the plate brush 50 can be locked on the roller 30, thereby hindering the movement of the ore, so as to provide continuous resistance and friction during the ore falling process, thereby enhancing the cleaning effect. The one-way rotation groove 512 is used to allow the plate brush 50 to rotate so that the plate brush 50 can be folded on the roller 30, thereby ensuring the smooth progress of the unloading process and preventing the ore from being stuck at the plate brush 50. A rotating head 520 is fixed at one end of the plate brush 50 close to the roller 30, and a rotating shaft 530 is fixed through the rotating head 520, and the rotating shaft 530 is rotatably mounted in the mounting seat 510. The one-way stopper 511 can abut against the side wall of the rotating head 520 to limit the rotation of the plate brush 50. A torsion spring 540 is provided between the rotating head 520 and the mounting seat 510 to apply elastic force to the plate brush 50 so that the plate brush 50 is perpendicular to the outer peripheral side of the rotating roller 30, so that it can more effectively hinder the movement of the ore to enhance the cleaning effect.

[0040] like Figure 5 and Figure 6As shown, specifically, the one-way stopper 511 is located on the side of the plate brush 50 facing the positive rotation direction of the roller 30, and the one-way rotation groove 512 is located on the side of the plate brush 50 facing the reverse rotation direction of the roller 30. Figure 5 In the position shown in , when the roller 30 rotates forward to enter the fast washing mode, the plate brush 50 on the roller 30 rotates from the roller 30 facing the upper right side to the roller facing vertically upward, and then rotates from the roller facing vertically upward to the roller facing the lower left side. In the process of the plate brush 50 rotating from the roller facing the upper right side to the roller facing vertically upward, under the action of the one-way rotation groove 512, the plate brush 50 can be folded downward on the roller 30 to ensure the smooth progress of the material discharge process; in the process of the plate brush 50 rotating from the roller facing vertically upward to the roller facing the lower left side, under the action of the one-way limiter 511, the plate brush 50 is limited in its downward rotation and can be locked on the roller 30 to guide the ore to fall quickly.

[0041] When the roller 30 rotates in the reverse direction and enters the strong washing mode, the plate brush 50 on the roller 30 rotates from the roller 30 facing the lower left side to the roller 30 facing vertically upward, and then rotates from the roller 30 facing vertically upward to the roller 30 facing the upper right side. In the process of the plate brush 50 rotating from the roller 30 facing the lower left side to the roller 30 facing vertically upward, under the action of the one-way limiter 511, the downward rotation of the plate brush 50 is limited and can be locked on the roller 30, thereby hindering the movement of the ore, so as to provide continuous resistance and friction during the ore falling process, and insert into the ore gap to clean the ore, thereby enhancing the cleaning effect; in the process of the plate brush 50 rotating from the roller 30 facing vertically upward to the roller 30 facing the upper right side, under the action of the one-way rotation groove 512, the plate brush 50 can be folded downward on the roller 30 to ensure the smooth progress of the material discharge process.

[0042] like Figures 1 to 3 As shown, the center column 80 is fixed in the cleaning section 220 and is coaxially arranged with the cylinder 20. The upper end of the center column 80 gradually decreases. The upper end of the center column 80 in the embodiment is hemispherical, which is convenient for the ore to be cleaned to fall to the surroundings. An installation area is formed inside the center column 80, and the installation area is used to install the drive assembly. The drive assembly includes a motor 810 and a transmission shaft 820. The output end of the motor 810 is connected to the transmission shaft 820 to drive the transmission shaft 820 to rotate. The transmission shaft 820 is provided with a driving gear corresponding to each roller 30. The end of each roller 30 close to the center column 80 extends into the installation area and is fixed with a driven gear meshing with the driving gear, so as to achieve the same direction of rotation of each roller 30 driven by gear meshing.

[0043] The cleaning water channel 610 is fixed to the inner wall of the cleaning part 220 and is spirally arranged synchronously with the plurality of rollers 30. Clean water flows into the cleaning water channel 610. A plurality of nozzles 60 are fixed to the cleaning water channel 610 and are evenly spaced so that the high-pressure water flow can impact the ore while the brush is cleaning, thereby enhancing the cleaning effect.

[0044] The water collecting plate 70 is fixed in the cleaning part 220. The water collecting plate 70 is distributed under the multiple rollers 30 and is spirally arranged synchronously with the multiple rollers 30. The inner hollow of the water collecting plate 70 forms a guide channel. The upper surface of the water collecting plate 70 is provided with multiple water holes to collect the sewage after cleaning and guide the sewage to be discharged, so that the sewage after cleaning is separated from the ore in time to ensure the cleaning effect. The water collecting plate 70 is tilted downward from the outside of the cylinder 20 to the inside of the cylinder 20, which can help turn over the ore that falls between two adjacent rollers 30 and change the axial position of the ore in the roller 30, further enhancing the cleaning effect. There are two water collecting plates 70 distributed along the radial direction of the cylinder 20.

[0045] The filter plate 90 is fixed in the discharge part 230, and a drainage channel 910 is formed between the filter plate 90 and the inner wall of the cylinder 20. The lower end of the guide channel is connected to the drainage channel 910. A drainage pipe 920 connected to the drainage channel 910 is fixed outside the discharge part 230 to discharge the sewage in a centralized manner. The ore filtered by the filter plate 90 is discharged in a centralized manner from the discharge port 231.

[0046] Thus, the embodiment of the cleaning machine for ore processing provides a more flexible cleaning mode, has strong adaptability to ores of different properties, and can process various types of ores.
