Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning, and particularly to a cleaning device for a medium box of a magnetic separator. Background Art

[0002] High-gradient magnetic separators are widely used in the separation of weakly magnetic minerals, and have the characteristics of large enrichment ratio, strong adaptability to fluctuations in feed particle size, concentration and grade. During operation, magnetic substances in the pulp will slowly adsorb on the magnetic medium of the medium box. As the high-gradient magnetic separator operates, the medium rods of the medium box will be completely coated, eventually blocking the entire medium box and seriously affecting the magnetic separation effect. Therefore, the magnetic medium box of the high-gradient magnetic separator needs to be removed regularly for cleaning. Since the covering on the medium rods is firmly adsorbed and difficult to clean, currently, using a high-pressure water gun to clean the medium box is a relatively effective method, or using sulfuric acid to soak and then rinse. However, using a high-pressure water gun for cleaning has the problem of high labor intensity. Using sulfuric acid to soak can reduce the cleaning difficulty, but there are environmental protection problems.

[0003] In this regard, the Chinese utility model patent CN215543487U provides a reciprocating high-gradient magnetic separator flushing device, which drives the screw to rotate through a driving unit, and then drives the nozzle to reciprocate axially along the screw through the nut on the screw, realizing the automatic cleaning operation of the magnetic medium box. However, since the nozzle only reciprocates linearly directly above the magnetic medium box, the flushing angle cannot completely cover the entire magnetic medium box, and there are still cleaning dead corners, resulting in poor cleaning effect. Summary of the Utility Model

[0004] The utility model provides a cleaning device for a medium box of a magnetic separator to solve the technical problem that the existing flushing device cannot achieve all-round cleaning of the medium box of the magnetic separator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will refer to the drawings for a detailed description of the embodiments of the present utility model, but the present utility model can be implemented in many different ways defined and covered by the following.

[0024] Figure 1 and Figure 2 jointly show the magnetic separator medium box cleaning device provided by an embodiment of the present utility model, which is used for automatically cleaning the medium box of a magnetic separator, can achieve all-round flushing without dead angles, and effectively improve the flushing efficiency and flushing effect.

[0025] Specifically, the magnetic separator medium box cleaning device includes a positioning seat 1, a displacement mechanism 2 and a flushing mechanism 3. The positioning seat 1 is provided with a clamping position 11 for fixing the medium box. The displacement mechanism 2 is erected above the clamping position 11. The displacement mechanism 2 includes an annular displacement component 21 and a driving component 22. The vertical projection of the annular displacement component 21 on the positioning seat 1 surrounds the clamping position 11. The driving component 22 is connected to the annular displacement component 21 and is used to drive the annular displacement component 21 to move annularly. The flushing mechanism 3 includes a nozzle 31 and a liquid supply component 32. The nozzle 31 is arranged on the annular displacement component 21. The liquid supply component 32 is connected to the nozzle 31 and is used to output high-pressure liquid through the nozzle 31. The annular displacement component 21 is used to drive the nozzle 31 to move around the medium box on the clamping position 11 under the drive of the driving component 22.

[0026] The magnetic separator medium box cleaning device first positions and fixes the medium box through the positioning seat 1, and then drives the nozzle 31 to move annularly above the medium box through the annular displacement component 21, so that the nozzle 31 can perform a full-round flushing operation around the medium box. During the movement of the nozzle 31, not only can the flushing position be gradually adjusted, but also the flushing direction can be continuously changed, and the medium box can be flushed from all around respectively, so as to better wash away the adsorbed substances on the medium box completely and effectively improve the flushing efficiency and flushing effect.

[0027] It should be understood that the annular displacement component 21 surrounds the clamping position 11, which does not limit that the annular displacement component 21 can only be in a perfect circular ring shape, but means that the surrounding line of the annular displacement component 21 is set according to the shapes of the clamping position 11 and the medium box. The annular displacement component 21 can specifically be set as a perfect circle, an ellipse or a waist-shaped hole structure, etc., as long as the vertical projection of the annular displacement component 21 on the positioning seat 1 can surround the clamping position 11 and the nozzle 31 can fully clean the medium box on the clamping position 11 during the moving flushing process.

[0028] Such as Figure 2As shown, preferably, the annular displacement assembly 21 includes a chain 211 and a limiting wheel 212. The chain 211 surrounds the clamping position 11 to form a closed-loop structure connected end to end. There are multiple limiting wheels 212. The multiple limiting wheels 212 are arranged at intervals along the circumference of the chain 211 and respectively abut against the chain 211 to keep the chain 211 in a preset annular structure. The limiting wheel 212 is in line contact with the chain 211 and is used to roll relative to the chain 211 when the chain 211 moves. By respectively limiting and fixing different positions of the chain 211 with multiple limiting wheels 212, while ensuring that the chain 211 maintains a preset annular structure, since the limiting wheel 212 is in line contact with the chain 211, rather than the chain 211 being wound around the limiting wheel 212, that is, the limiting wheel 212 does not need to fill the inner space of the chain 211 at the bending position, and the radius of the limiting wheel 212 is smaller than the bending radius of the chain 211 at the bending position, the size of the limiting wheel 212 can be flexibly reduced, the occupied space of the limiting wheel 212 can be reduced, and the limiting wheel 212 can be prevented from blocking the flushing operation of the nozzle 31.

[0029] Preferably, the limiting wheel 212 includes an inner limiting wheel 2121 and an outer limiting wheel 2122. The inner limiting wheel 2121 abuts against the inner ring of the chain 211, and the outer limiting wheel 2122 abuts against the outer ring of the chain 211. Both the inner limiting wheel 2121 and the outer limiting wheel 2122 are arranged in multiple numbers at intervals along the circumference of the chain 211, and the inner limiting wheel 2121 and the outer limiting wheel 2122 are arranged in one-to-one correspondence. By respectively abutting against the inner and outer sides of the chain 211 with the inner limiting wheel 2121 and the outer limiting wheel 2122, the chain 211 can neither deform outwards nor inwards, and the chain 211 can be better limited and fixed.

[0030] Preferably, the flushing mechanism 3 further includes a mounting bracket 33. The first end of the mounting bracket 33 is connected to the chain 211. The second end of the mounting bracket 33 bypasses the limiting position of the inner limiting wheel 2121 from above the inner limiting wheel 2121 and is arranged towards the inner ring of the chain 211. The nozzle 31 is arranged at the second end of the mounting bracket 33. By mounting the nozzle 31 through the mounting bracket 33, the nozzle 31 can be arranged to bypass the limiting position of the inner limiting wheel 2121, preventing the inner limiting wheel 2121 from blocking the flushing operation of the nozzle 31 and ensuring an all-round flushing effect.

[0031] Furthermore, the mounting bracket 33 is detachably connected to the chain 211, and / or the nozzle 31 is detachably connected to the mounting bracket 33, so as to disassemble and replace nozzles 31 of different specifications, realize different spraying functions and facilitate maintenance and repair.

[0032] Preferably, the driving assembly 22 includes a driving motor (not shown in the figure, the same below) and a driving gear 221 connected to the output shaft of the driving motor. The driving gear 221 meshes with the outer ring of the chain 211 and is used to drive the chain 211 to move under the drive of the driving motor. Since the driving gear 221 is arranged on the outer ring of the chain 211, it will not block the inner ring of the chain 211, which is more conducive to the nozzle 31 performing a full-round flushing operation on the inner ring of the chain 211.

[0033] More preferably, the limiting wheel 212 further includes a driving limiting wheel 2123. The driving limiting wheel 2123 abuts against the inner ring of the chain 211 and is arranged opposite to the driving gear 221. By the driving limiting wheel 2123 reversely pressing against the chain 211, the chain 211 is clamped and fixed between the driving limiting wheel 2123 and the driving gear 221, so as to ensure that the driving gear 221 is in close contact with the chain 211 and can stably drive the chain 211 to move from the outer ring of the chain 211.

[0034] Furthermore, each link of the chain 211 is provided with a driving hole 2111. The driving gear 221 includes driving teeth 2211 corresponding to the driving holes 2111. The driving gear 221 is used to drive the chain 211 to move by inserting the driving teeth 2211 into the driving holes 2111 when rotating, so as to realize the driving action.

[0035] Preferably, the annular displacement assembly 21 further includes a roller 213 arranged at the bottom of the chain 211. Above the positioning seat 1, there is a support platform (not shown in the figure, the same below). The roller 213 is placed on the support platform and is used to roll along the support platform. By the support platform supporting the annular displacement assembly 21, the chain 211 moves on the support platform through the roller 213, which can reduce the friction force, ensure the smooth movement of the chain 211, avoid jamming, and thus improve the flushing stability of the nozzle 31.

[0036] Furthermore, an annular limiting track is arranged on the support platform. The roller 213 is embedded in the annular limiting track and is used to guide and move along the annular limiting track. Through the cooperation of the annular limiting track and the roller 213, the annular movement line of the chain 211 is guided and limited, effectively improving the movement accuracy and stability of the chain 211.

[0037] It should be noted that in other embodiments, when the annular limiting track is provided on the support platform, the annular displacement assembly 21 may not need to be provided with the limiting wheels 212. Through the annular limiting track, the chain 211 can also be maintained in a preset annular structure, and the structure can be further simplified, completely freeing up the inner space of the chain 211, and not blocking the nozzle 31 at all, thereby improving the flushing effect of the nozzle 31.

[0038] As Figure 1 shown, the magnetic separator medium box cleaning device further includes a sealing cover 4. The sealing cover 4 covers the positioning seat 1 and encloses a cleaning chamber 41 with the positioning seat 1. The displacement mechanism 2 is arranged in the cleaning chamber 41. That is, by covering the medium box with the sealing cover 4 in a closed space for flushing operation, it can not only prevent external dust from entering the cleaning chamber 41 and affecting the flushing effect, but also prevent the adsorbed substances flushed out from flying outwards, avoiding environmental impact and facilitating collection and recycling.

[0039] Preferably, the positioning seat 1 is further provided with a drain groove (not shown in the figure, the same below) and a drain valve 12. The clamping position 11 is provided with a hollow structure. The drain groove is located below the clamping position 11 and is inclined downward in the direction towards the drain valve 12. The drain valve 12 is used to conduct the drain groove to the outside of the positioning seat 1. The drain groove is used to collect the flushing liquid and the adsorbed substances flushed out and guide them to the drain valve 12 by using the inclined structure of the drain groove, which is convenient for quick drainage.

[0040] Preferably, the magnetic separator medium box cleaning device further includes a timing mechanism 5. The timing mechanism 5 is used to time the running time of the driving component 22 and the liquid supply component 32. By controlling the cleaning time through the timing mechanism 5, the driving component 22 and the liquid supply component 32 are stopped simultaneously after the annular displacement component 21 moves one cycle or multiple cycles. There is no need for manual control of the cleaning time, which ensures the cleaning effect and avoids waste of resources. It should be understood that the specific components and working principles of the timing mechanism 5 all belong to the prior art, and this embodiment does not involve the improvement of the control method of the timing mechanism 5.

[0041] Preferably, the liquid supply component 32 includes a water tank 321, a high-pressure pump 322 and a water pipe 323 connected in sequence. One end of the water pipe 323 away from the high-pressure pump 322 is connected to the nozzle 31. The high-pressure pump 322 is used to pump out the flushing liquid in the water tank 321 and transport it to the nozzle 31 along the water pipe 323. Since the liquid supply component 32 is equipped with its own water tank 321, the installation position can be flexibly adjusted to ensure sufficient water source.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
