Description

Technical Field

[0001] The invention relates to the technical field of hydraulic oil purification equipment, and in particular to a hydraulic oil purification device for hydraulic equipment. Background Art

[0002] After being used for a certain period of time, hydraulic oil will be mixed with mechanical impurities such as grinding chips and dust, and needs to be filtered and purified. The filtering device used in current hydraulic equipment is the hydraulic equipment itself. This hydraulic device is placed inside the hydraulic equipment. When damaged, most hydraulic equipment needs to disassemble the entire equipment to replace the filtering device. The operation is more complicated, which reduces the efficiency of filtering and purification and has poor practicality.

[0003] In order to solve the above problems, a Chinese patent with announcement number CN220365809U discloses a hydraulic oil filter device for hydraulic equipment, including a lower tank body, the upper end of the lower tank body is fixedly connected to the upper tank body, the lower surface of the upper tank body is fixedly connected to the upper end connection block, the upper surface of the lower tank body is fixedly connected to the lower end connection block, the center of the front end outer wall of the lower tank body is fixedly connected to the first pipe fixing block, the inner wall of the first pipe fixing block is fixedly connected to the first liquid discharge pipe, the center of the rear end outer wall of the lower tank body is fixedly connected to the second pipe fixing block, and the inner wall of the second pipe fixing block is fixedly connected to the second liquid discharge pipe. The device has multiple layers of filter screens inside, and the magnetic filter screen provided therein can adsorb the debris generated by pressure in the equipment on the filter screen to reduce the damage to the ordinary filter screen, extend the service life of the filter device, and thus extend the service life of the hydraulic equipment.

[0004] The above-mentioned device has the following problems during actual use: 1. The device requires workers to regularly disassemble and remove the filter to replace the filter to ensure that the hydraulic oil can be smoothly filtered and purified under the action of the filter. However, regular manual disassembly and replacement of the filter will, on the one hand, delay the progress of hydraulic oil filtration and purification and reduce the purification efficiency, and on the other hand, bring unnecessary trouble to the workers' work and increase the workers' workload; 2. If the filter is directly discarded without cleaning after being disassembled, the economic cost will increase. However, if the filter is only cleaned once, some debris will still remain on the filter, reducing the purification efficiency of the filter. However, if the worker cleans the filter many times, the worker's workload will increase, the work will be cumbersome, and the filter may even be incompletely cleaned, thereby affecting the reuse of the filter. Summary of the invention

[0005] The invention provides a hydraulic oil purification device for hydraulic equipment, so as to solve the problem that the existing filtering device cannot clean the filter net during the period when the filter net filters and purifies the hydraulic oil.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a hydraulic oil purification device for hydraulic equipment, comprising a filter cartridge with an inlet and an outlet, and also comprising a purification mechanism arranged in the filter cartridge; the purification mechanism comprises a rotating shaft, a filter plate, purification components symmetrically arranged on both sides of the rotating shaft along the axial direction of the rotating shaft, and a driving component for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the filter cartridge; the filter plate is connected to the filter cartridge; the purification component comprises a fixed block, a stirring block, a cleaning block, and a plurality of through holes are equidistantly opened along the length direction of the cleaning block; the fixed block is fixedly connected to the rotating shaft; the stirring block is fixedly connected to the fixed block; the cleaning block is connected to the stirring block, and the free end of the cleaning block is in contact with the filter plate.

[0007] The principles and advantages of this solution are:

[0008] 1. Put the hydraulic oil into the filter cylinder along the inlet, so that the filter plate can filter and purify the hydraulic oil. During the filtration of the filter plate, the debris mixed in the hydraulic oil can be filtered and retained on the filter plate, while the hydraulic oil can flow out of the filter plate and finally discharged from the outlet, that is, the separation of debris and hydraulic oil is achieved, and the filtration and purification of the hydraulic oil is completed.

[0009] 2. When the filter plate is filtering and purifying the hydraulic oil, the stirring block moves along the circumferential direction of the filter plate, so that the stirring block can stir the hydraulic oil in the filter cylinder. During the movement of the stirring block, on the one hand, the flow rate of the hydraulic oil can be accelerated, so that the hydraulic oil can flow through the filter plate faster, which speeds up the purification efficiency of the filter plate and enhances the purification effect of the filter plate; on the other hand, it can change the location of the debris, reduce the number of debris accumulation, reduce the probability of the filter plate being blocked by debris, and thus ensure that the hydraulic oil can flow out of the filter plate more fully.

[0010] 3. During the movement of the stirring block, the cleaning block moves synchronously. During the movement of the cleaning block, the cleaning block has a certain force, so the cleaning block can scrape off the debris adhering to the filter plate, so that the debris will no longer adhere to the filter plate, thereby improving the filtration and purification quality of the filter plate, further reducing the probability of clogging of the filter plate, and ensuring that the hydraulic oil can flow out of the filter plate comprehensively.

[0011] Furthermore, the purification component also includes an auxiliary part; the auxiliary part includes an auxiliary shaft, a first cam, a first spring, a top hole opened on the stirring block, and an auxiliary unit for driving the auxiliary shaft to rotate; the cleaning block is slidably connected to the top hole; the auxiliary shaft is rotatably connected to the stirring block; the first cam is fixedly connected to the auxiliary shaft, and the first cam is against the cleaning block; the two ends of the first spring are respectively connected to the cleaning block and the top hole.

[0012] Through the cooperation of the first cam and the first spring, the cleaning block can reciprocate along the length direction of the top hole. During the horizontal reciprocating motion of the cleaning block relative to the length direction of the stirring block, the cleaning block has a strong force, so that the debris with strong adhesion can be easily scraped off under the horizontal reciprocating motion of the cleaning block, further reducing the amount of debris adhering to the filter plate, thereby enhancing the cleaning effect of the cleaning block, improving the working efficiency of the cleaning block, and ensuring that the debris on the filter plate can be completely cleaned.

[0013] Furthermore, a placement hole is provided on the filter plate; it also includes a collecting cylinder; the collecting cylinder is fixedly connected to the filter cylinder, and the collecting cylinder is connected to the placement hole; the purification component also includes a linkage part; the linkage part includes a first screw, a first guide rod, a nut seat, a bristle layer, and a power unit for driving the first screw to rotate; the first screw is rotationally connected to the stirring block; the first guide rod is fixedly connected to the stirring block; the nut seat is threadedly connected to the first screw, and the nut seat is slidingly connected to the first guide rod; the bristle layer is fixedly connected to the nut seat, the free end of the bristle layer is attached to the filter plate, the bristle layer is attached to the cleaning block, and the collecting cylinder is located on the movement trajectory of the bristle layer.

[0014] When the cleaning block scrapes the debris on the filter plate, the scraped debris can be accumulated on the side of the cleaning block close to the bristle layer, and then the bristle layer reciprocates along the length direction of the first guide rod, so that the bristle layer can drive the debris accumulated on the cleaning block to move to the location of the collection tube. Through the above movement, the amount of debris retained on the filter plate is reduced, so that all the debris can fall into the collection tube, completing the collection of the debris, facilitating the subsequent centralized cleaning of the debris by the workers, reducing the workers' workload, and improving the efficiency of debris recovery and cleaning.

[0015] Moreover, the bristle layer can further clean the filter plate during its movement, that is, the bristle layer can sweep away the debris adhering to the filter plate, reducing the probability of the filter plate being blocked, thereby enhancing the cleaning effect of the filter plate, improving the purification quality of the filter plate, and ensuring that the hydraulic oil can efficiently flow out of the filter plate. That is, through the cooperation of the bristle layer and the cleaning block, it is ensured that the filter plate can be cleaned more completely and thoroughly, comprehensively enhancing the cleaning effect of the filter plate, and further improving the purification efficiency of the filter plate.

[0016] Furthermore, the linkage part also includes a plurality of linkage blocks; the plurality of linkage blocks are arranged equidistantly along the length direction of the cleaning block; the linkage blocks are fixedly connected to the cleaning blocks, and the linkage blocks are located on the movement track of the bristle layer.

[0017] During the movement of the bristle layer, the linkage block and the cleaning block move synchronously, that is, the linkage block acts on the bristle layer, so that the bristle layer can continuously swing. Therefore, while the bristle layer reciprocates along the length direction of the first guide rod, the bristle layer itself can also swing. During the swinging of the bristle layer, the bristle layer has a certain force. On the one hand, the bristle layer can more efficiently push the debris into the collection tube, thereby improving the efficiency of debris recovery; on the other hand, the bristle layer can clean the filter plate more effectively, thereby further reducing the amount of debris adhering to the filter plate, reducing the probability of clogging of the filter plate, and enhancing the filtering effect of the filter plate.

[0018] Moreover, when the linkage block is beating the bristle layer, the amount of debris adhering to the bristle layer can be reduced, so that the debris eventually falls onto the filter plate, thereby cleaning the bristle layer, enhancing the cleaning effect of the bristle layer on the filter plate, and improving the cleaning efficiency of the bristle layer.

[0019] Furthermore, the filter plate is slidingly connected to the filter cylinder and the collection cylinder respectively; the linkage part also includes a vibration unit; the vibration unit includes a second cam, a guide block, a vibration block, a second spring, and a third spring; the second cam is fixedly connected to the second screw; the guide block is fixedly connected to the stirring block; a guide groove is opened on the guide block, the vibration block is slidingly connected to the guide groove, the vibration block abuts against the filter plate, and the second cam abuts against the vibration block; the two ends of the second spring are respectively connected to the vibration block and the guide groove; the two ends of the third spring are respectively connected to the filter plate and the filter cylinder.

[0020] The filter plate can be continuously vibrated by the joint action of the vibration block, the second spring and the third spring. During the vibration of the filter plate, on the one hand, the debris blocked on the filter plate can be prompted to make vertical reciprocating motion, so that the debris no longer blocks the filter holes on the filter plate, and finally falls on the filter plate, further reducing the probability of the filter plate being blocked; on the other hand, during the vibration of the filter plate, the flow rate of the hydraulic oil can be accelerated, so that the hydraulic oil can quickly flow out through the filter plate, thereby accelerating the purification efficiency of the hydraulic oil and shortening the purification treatment time of the hydraulic oil.

[0021] Moreover, during the vibration, the filter plate can cooperate with the swing of the bristle layer, so that the bristle layer can efficiently clean and sweep the filter plate, comprehensively enhancing the cleaning effect of the bristle layer on the filter plate, so that the filter plate can be cleaned more comprehensively under the action of the bristle layer.

[0022] Furthermore, the auxiliary part also includes a stirring unit; the stirring unit includes a short shaft, a stirring blade, and a driving unit for driving the short shaft to rotate; the short shaft is rotatably connected to the stirring block; and the stirring blade is fixedly connected to the short shaft.

[0023] The driving unit drives the short shaft to rotate forward and reverse continuously, so that the stirring blade can alternately stir clockwise and counterclockwise, increasing the stirring treatment method of the hydraulic oil and making the hydraulic oil move disorderly. That is, the debris can be mixed more evenly in the hydraulic oil, further reducing the probability of debris accumulation, ensuring that the filter plate can always efficiently filter the hydraulic oil, and speeding up the progress of hydraulic oil filtration and purification.

[0024] That is, through the stirring of the stirring block and the stirring blade, on the one hand, the flow rate of the hydraulic oil can be accelerated, ensuring that the hydraulic oil can flow out of the outlet along the filter plate more efficiently and quickly; on the other hand, the probability of debris accumulation into agglomerations is reduced, thereby improving the filtering quality of the filter plate.

[0025] Furthermore, the rotating shaft is a second screw; the purification mechanism also includes an extrusion assembly; the extrusion assembly includes a second guide rod, an extrusion plate, and an auxiliary hole opened on the extrusion plate; the second guide rod is fixedly connected to the filter cartridge; the extrusion plate is threadedly connected to the second screw, and the extrusion plate is slidably connected to the second guide rod.

[0026] During the hydraulic oil filtration, the vertical downward movement of the extrusion plate enables the extrusion plate to squeeze the hydraulic oil, thereby accelerating the flow rate of the hydraulic oil, causing the hydraulic oil to flow to the location of the filter plate, thereby further accelerating the filtering and purification efficiency of the filter plate on the hydraulic oil.

[0027] That is, under the stirring action of the stirring block and the stirring blade, the vibration action of the filter plate and the extrusion action of the extrusion plate, the flow velocity of the hydraulic oil can be comprehensively improved, so that the hydraulic oil can flow out of the filter plate efficiently, thereby accelerating the efficiency of filtering and purifying the hydraulic oil.

[0028] Furthermore, it also includes an annular rack; the annular rack is fixedly connected to the filter cartridge; the auxiliary unit is a first gear; the first gear is fixedly connected to the auxiliary shaft, and the first gear is meshed with the annular rack.

[0029] When the auxiliary shaft moves synchronously with the stirring block in a circumferential direction, the first gear moves synchronously. When the first gear moves, the first gear is engaged with the annular rack, so the first gear rotates. When the first gear rotates, the auxiliary shaft rotates synchronously, that is, the auxiliary shaft can rotate while the auxiliary shaft moves in a circumferential direction.

[0030] Furthermore, the power unit includes a worm and a worm wheel; the worm is fixedly connected to the auxiliary shaft; the worm wheel is fixedly connected to the first screw; and the worm wheel is meshed with the worm.

[0031] When the auxiliary shaft rotates, the worm rotates synchronously. When the worm rotates, the worm wheel rotates synchronously. When the worm wheel rotates, the first screw rotates synchronously.

[0032] Furthermore, the driving unit includes a second gear and a rack; the second gear is fixedly connected to the short shaft; the rack is fixedly connected to the cleaning block, and the rack is meshed with the second gear.

[0033] When the cleaning block reciprocates along the length direction of the top hole, the rack moves synchronously. During the movement of the rack, the rack meshes with the second gear, so that the second gear can rotate forward and reverse. During the rotation of the second gear, the short shaft rotates synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Specific implementation process:

[0054] The hydraulic oil is put into the filter cartridge 1 along the inlet 35, so that the filter plate 3 can filter and purify the hydraulic oil. During the filtering process of the filter plate 3, the debris mixed in the hydraulic oil can be filtered and retained on the filter plate 3, while the hydraulic oil can flow out from the filter plate 3 and finally be discharged from the outlet 34, that is, the separation of the debris and the hydraulic oil is achieved, and the filtering and purification of the hydraulic oil is completed.

[0055] While the filter plate 3 is filtering and purifying the hydraulic oil, the servo motor 32 is started, and the second screw is driven to rotate by the output shaft of the servo motor 32. During the rotation of the second screw, the fixed block 4 moves synchronously. During the movement of the fixed block 4, the stirring block 5 moves circumferentially along the circumferential direction of the filter plate 3 driven by the fixed block 4.

[0056] The stirring block 5 can stir the hydraulic oil in the filter cartridge 1 by moving the stirring block 5 along the circumferential direction of the filter plate 3. During the movement of the stirring block 5, on the one hand, the flow rate of the hydraulic oil can be accelerated, so that the hydraulic oil can flow through the filter plate 3 faster, thereby accelerating the purification efficiency of the filter plate 3 and enhancing the purification effect of the filter plate 3; on the other hand, the position of the debris can be changed, the number of debris accumulation groups can be reduced, and the probability of the filter plate 3 being blocked by debris is reduced, thereby ensuring that the hydraulic oil can flow out of the filter plate 3 more fully.

[0057] During the movement of the stirring block 5, the cleaning block 6 moves synchronously. During the movement of the cleaning block 6, the cleaning block 6 has a certain force, so the cleaning block 6 can scrape off the debris adhering to the filter plate 3, so that the debris will no longer adhere to the filter plate 3, thereby improving the filtration and purification quality of the filter plate 3, further reducing the probability of clogging of the filter plate 3, and ensuring that the hydraulic oil can flow out of the filter plate 3 in an all-round way.

[0058] The auxiliary shaft 8 moves synchronously with the stirring block 5 in the circumferential direction, and the first gear 27 moves synchronously. During the movement of the first gear 27, the first gear 27 is engaged with the annular rack 26, so that the first gear 27 rotates. During the rotation of the first gear 27, the auxiliary shaft 8 rotates synchronously, that is, while the auxiliary shaft 8 moves in the circumferential direction, the auxiliary shaft 8 can also rotate.

[0059] During the rotation of the auxiliary shaft 8, the first cam 9 rotates synchronously. During the rotation of the first cam 9, when the protrusion of the first cam 9 abuts against the cleaning block 6, the cleaning block 6 moves toward the position where the second screw is located, and the first spring is compressed; when the protrusion of the first cam 9 no longer abuts against the cleaning block 6, the cleaning block 6 is reset under the action of the first spring, and the cleaning block 6 moves away from the position where the second screw is located. Therefore, the cleaning block 6 can reciprocate along the length direction of the top hole 36.

[0060] During the lateral reciprocating motion of the cleaning block 6 relative to the length direction of the stirring block 5, the cleaning block 6 has a strong force, so that debris with strong adhesion can be easily scraped off under the lateral reciprocating motion of the cleaning block 6, further reducing the amount of debris adhering to the filter plate 3, thereby enhancing the cleaning effect of the cleaning block 6, improving the working efficiency of the cleaning block 6, and ensuring that the debris on the filter plate 3 can be completely cleaned up.

[0061] While the cleaning block 6 is scraping the debris on the filter plate 3, the scraped debris can be accumulated on the side of the cleaning block 6 close to the bristle layer 14. During the accumulation of debris, the worm 28 rotates synchronously with the auxiliary shaft 8. During the rotation of the worm 28, the worm wheel 29 meshes with the worm 28, so that the worm wheel 29 rotates. During the rotation of the worm wheel 29, the first screw 11 rotates synchronously. During the rotation of the first screw 11, the nut seat 13 can reciprocate along the length direction of the first guide rod 12. During the movement of the nut seat 13, the bristle layer 14 moves synchronously.

[0062] During the movement of the bristle layer 14 toward the position where the collecting barrel 10 is located along the length direction of the first guide rod 12, the bristle layer 14 can drive the debris accumulated on the cleaning block 6 to move toward the position where the collecting barrel 10 is located. Through the above movement, the amount of debris retained on the filter plate 3 is reduced, so that the debris can all fall into the collecting barrel 10, completing the collection of the debris, facilitating the subsequent centralized cleaning of the debris by the workers, reducing the workload of the workers, and improving the efficiency of the recycling and cleaning of the debris.

[0063] Moreover, the bristle layer 14 can further clean the filter plate 3 during the movement, that is, the bristle layer 14 can sweep away the debris adhering to the filter plate 3, thereby reducing the probability of clogging of the filter plate 3, thereby enhancing the cleaning effect of the filter plate 3, improving the purification quality of the filter plate 3, and ensuring that the hydraulic oil can efficiently flow out of the filter plate 3. That is, through the cooperation of the bristle layer 14 and the cleaning block 6, it is ensured that the filter plate 3 can be cleaned more completely and thoroughly, comprehensively enhancing the cleaning effect of the filter plate 3, and further improving the purification efficiency of the filter plate 3.

[0064] During the movement of the bristle layer 14, the linkage block 15 moves synchronously with the cleaning block 6, that is, the linkage block 15 acts on the bristle layer 14, so that the bristle layer 14 can continuously swing. Therefore, while the bristle layer 14 reciprocates along the length direction of the first guide rod 12, the bristle layer 14 itself can also swing. During the swinging of the bristle layer 14, the bristle layer 14 has a certain force. On the one hand, the bristle layer 14 can more efficiently push the debris into the collection tube 10, thereby improving the efficiency of recycling the debris; on the other hand, the bristle layer 14 can clean the filter plate 3 more effectively, thereby further reducing the amount of debris adhering to the filter plate 3, reducing the probability of clogging of the filter plate 3, and enhancing the filtering effect of the filter plate 3.

[0065] Moreover, when the linkage block 15 is beating the bristle layer 14 , the amount of debris adhering to the bristle layer 14 can be reduced, so that the debris eventually falls onto the filter plate 3 , thereby cleaning the bristle layer 14 , enhancing the cleaning effect of the bristle layer 14 on the filter plate 3 , and improving the cleaning efficiency of the bristle layer 14 .

[0066] During the rotation of the first screw rod 11, the second cam 16 rotates synchronously. During the rotation of the second cam 16, when the raised portion of the second cam 16 abuts against the vibration block 18, the vibration block 18 moves vertically downward, and the second spring is compressed; when the raised portion of the second cam 16 no longer abuts against the vibration block 18, the vibration block 18 is reset under the action of the second spring, and the vibration block 18 moves vertically upward. Therefore, the vibration block 18 can perform vertical reciprocating motion.

[0067] The vibration block 18 reciprocates vertically, and the filter plate 3 is continuously vibrated under the joint action of the third spring and the vibration block 18. During the vibration of the filter plate 3, on the one hand, the debris blocked on the filter plate 3 can be prompted to reciprocate vertically, so that the debris no longer blocks the filter holes on the filter plate 3, and finally falls on the filter plate 3, further reducing the probability of the filter plate 3 being blocked; on the other hand, during the vibration of the filter plate 3, the flow rate of the hydraulic oil can be accelerated, so that the hydraulic oil can quickly flow out through the filter plate 3, thereby accelerating the purification efficiency of the hydraulic oil and shortening the purification processing time of the hydraulic oil.

[0068] Moreover, during the vibration, the filter plate 3 can cooperate with the swing of the bristle layer 14 , so that the bristle layer 14 can efficiently clean and sweep the filter plate 3 , comprehensively enhancing the cleaning effect of the bristle layer 14 on the filter plate 3 , so that the filter plate 3 can be cleaned more comprehensively under the action of the bristle layer 14 .

[0069] While the cleaning block 6 is reciprocating along the length direction of the top hole 36, the rack 31 moves synchronously. During the movement of the rack 31, since the rack 31 is meshed with the second gear 30, the second gear 30 can rotate forward and reverse. During the rotation of the second gear 30, the short shaft 21 rotates synchronously. During the continuous forward and reverse rotation of the short shaft 21, the stirring blade 22 can alternately stir clockwise and counterclockwise, increasing the stirring treatment method for the hydraulic oil and allowing the hydraulic oil to move in a disordered manner. That is, the debris can be more evenly mixed in the hydraulic oil, further reducing the probability of debris accumulation, ensuring that the filter plate 3 can always efficiently filter the hydraulic oil, and speeding up the progress of filtering and purifying the hydraulic oil.

[0070] That is, through the stirring of the stirring block 5 and the stirring blade 22, on the one hand, the flow rate of the hydraulic oil can be accelerated, ensuring that the hydraulic oil can flow out from the outlet 34 along the filter plate 3 more efficiently and quickly; on the other hand, the probability of debris accumulation is reduced, thereby improving the filtering quality of the filter plate 3.

[0071] During the rotation of the second screw, the extrusion plate 24 can move vertically downward along the length direction of the second guide rod 23. The vertical downward movement of the extrusion plate 24 can squeeze the hydraulic oil, thereby accelerating the flow speed of the hydraulic oil, and causing the hydraulic oil to flow to the position where the filter plate 3 is located, thereby further accelerating the filtering and purification efficiency of the filter plate 3 on the hydraulic oil.

[0072] That is, under the stirring action of the stirring block 5 and the stirring blade 22, the vibration action of the filter plate 3, and the extrusion action of the extrusion plate 24, the flow velocity of the hydraulic oil can be comprehensively improved, so that the hydraulic oil can flow out of the filter plate 3 efficiently, thereby accelerating the efficiency of filtering and purifying the hydraulic oil.
