Description

Technical Field

[0001] The present invention relates to the technical field of oil filter cleaning equipment, and specifically relates to a comprehensive cleaning equipment for oil filters. Background Art

[0002] As a key component of the engine lubrication system, the main function of the oil filter is to filter harmful impurities in the oil, ensure a clean oil supply to each moving pair inside the engine, and achieve effective lubrication, cooling, and cleaning effects, thereby extending the service life of these components. However, after the filter is processed and formed, a large amount of stains and dust often adhere to the surface of its housing, so special cleaning equipment is required for cleaning. The existing filter cleaning equipment usually sets stirring components in the soaking tank to improve the cleaning effect by stirring the cleaning liquid. However, the existing cleaning methods are difficult to ensure that all parts of the filter can be evenly and thoroughly cleaned, and there may still be cleaning dead corners, affecting the final cleaning quality.

[0003] Currently, a circulating cleaning equipment for an oil filter and its use method in a Chinese invention patent application (publication number CN113083785A) includes a main chassis, a spraying box body, and a recycling box body. A box door is arranged on the front of the main chassis, a water inlet pipe is fixedly communicated with the side of the main chassis, a plurality of straight pipes are fixedly communicated between the inner top wall of the main chassis and the inner bottom wall of the spraying box body, a plurality of connecting pipes are fixedly communicated between the inner bottom wall of the main chassis and the inner top wall of the recycling box body, a recycling pipe is communicated between the recycling box body and the inner side wall of the spraying box body, a water pump is arranged in the middle of the recycling pipe, a water outlet pipe is fixedly communicated with the inner side wall of the recycling box body, two symmetrically arranged first electric push rods are fixedly installed on the inner top wall of the main chassis, a clamping control board is fixedly installed between the output ends of the two first electric push rods, and a uniformly distributed clamping mechanism is arranged at the bottom of the clamping control board.

[0004] In the above prior art, the method of fixing the filter housing with clamping balls reduces the contact area between the fixture and the filter, exposing almost all parts of the filter surface, and using the cleaning liquid to fully clean the filter surface, maximizing the effective cleaning area of the filter while avoiding contact between the stirring component and the filter. However, the filter remains stationary during the cleaning process, and the flow of the cleaning liquid may not be uniform enough, and there may be cleaning dead corners. Therefore, there is a need for a comprehensive cleaning equipment that can make the oil filter rotate automatically during the cleaning process to overcome the problem of cleaning dead corners in the traditional fixed method. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, a comprehensive cleaning device for an oil filter is provided. In the present invention, a high-pressure water flow is guided through a water spraying channel to act on the surface of the filter in a tangential direction, promoting the cleaning liquid in the cleaning chamber to form a swirling state, enabling the filter to rotate on its own on the rotating support assembly, ensuring comprehensive cleaning and using centrifugal force to remove deep dirt.

[0006] To solve the problems of the prior art, the present invention provides a comprehensive cleaning device for an oil filter, including a cleaning pool. A number of cleaning chambers capable of accommodating the filter are arranged in a matrix in the cleaning pool. Each cleaning chamber is provided with a dynamic cleaning mechanism. The dynamic cleaning mechanism includes a rotating support assembly for placing the filter and a flushing assembly for cleaning the filter. In the working state, the rotating support assembly cooperates with the flushing assembly to drive the filter to rotate. The flushing assembly has a water spraying channel arranged in a tangential direction towards the surface of the filter.

[0007] The flushing assembly includes a plate member and nozzles provided on the plate member for cleaning the filter from the outside to the inside. The plate member is provided with the water spraying channel opened in a tangential direction towards the surface of the filter. A number of nozzles communicating with the water spraying channel are evenly distributed along the axial direction of the filter on the plate member.

[0008] Preferably, a number of the plate members are evenly distributed around the rotation axis direction of the filter in the cleaning chamber. When the nozzles on all the plate members spray water simultaneously, the cleaning liquid around the filter is in a swirling state, enabling the filter to be in a self-rotating cleaning state in the cleaning liquid.

[0009] Preferably, each plate member can rotate in the cleaning chamber to adjust the channel opening orientation of the water spraying channel according to the size of the filter. The rotation direction of the plate member is perpendicular to the rotation axis direction of the filter.

[0010] Preferably, an upper shaft connection part and a lower shaft connection part for respectively rotatably connecting the upper and lower ends of all the plate members are provided in the cleaning chamber. A synchronous drive structure for driving all the plate members to rotate is provided on the lower shaft connection part.

[0011] Preferably, the flushing assembly further includes a spray pipe for cleaning the filter from the inside to the outside. A number of spray openings opened towards the nozzles are evenly distributed along the axial direction of one side of the spray pipe.

[0012] Preferably, the rotating support assembly includes a lower ball bearing seat arranged at the bottom of the cleaning chamber. The lower ball bearing seat has a fixed part and a rotating part. A sponge clamp capable of allowing the lower end of the filter to be clamped therein is provided on the rotating part. When the filter is affected by the swirling flow, the rotating part drives the filter to rotate together.

[0013] Preferably, the rotary support assembly further includes an upper ball bearing seat disposed at the top of the cleaning chamber body. The upper ball bearing seat has a plurality of first spheres evenly distributed around the rotation axis direction of the rotating part, and each of the first spheres can rollingly contact the outer side of the upper end of the filter.

[0014] Preferably, each first sphere can move towards the rotation axis direction of the rotating part. The upper ball bearing seat further has a guide rail for each first sphere to move, and a push rod capable of pushing the first sphere to move is provided on each guide rail.

[0015] Preferably, directly above the lower ball bearing seat, there is a lowering rod capable of accurately bringing the filter into the cleaning chamber body. An elastic inner support part capable of adaptively clamping the upper end of the filter is provided at the lower end of the lowering rod, and the elastic inner support part has a second sphere capable of rollingly contacting the inner side of the upper end of the filter.

[0016] The beneficial effects of this application compared with the prior art are as follows: 1. In the present invention, the high-pressure water flow is guided by the water spraying channel to act on the surface of the filter in a tangential direction, so that the cleaning liquid in the cleaning chamber body forms a swirling state, prompting the filter to rotate by itself on the rotary support assembly. This not only ensures the comprehensive cleaning of the filter, but also uses centrifugal force to throw out the fine particles and sediments deep in the micropores of the filter material, realizing deep cleaning.

[0017] Compared with static cleaning, it realizes the efficient and thorough cleaning of the oil filter. It improves the cleaning efficiency and quality, enables the filter to restore the best working state, extends the service life and ensures the filtering performance.

[0018] 2. In the present invention, the synchronous drive structure adjusts the angles of all the plate members according to the size of the filter, ensuring that the high-pressure water flow acts on the surface of the filter at the best angle. This makes the angle between each plate member and the filter equal, realizing uniform coverage. Subsequently, the nozzles on all the plate members spray high-pressure water flow simultaneously, so that the cleaning liquid forms a swirling state, prompting the filter to rotate by itself.

[0019] At the same time, combined with the water flow spraying of the spray pipe, the inner side of the filter is cleaned during the rotation process, ensuring cleaning without dead angles. This enables the inside and outside of the filter to be comprehensively and carefully cleaned, restores the best working state, extends the service life and ensures the filtering performance.

[0020] 3. In the present invention, through the synergistic effect of the lower ball bearing seat and the upper ball bearing seat, the stable self-rotation of the filter during the cleaning process is realized. Before cleaning, the sponge clamp of the lower ball bearing seat firmly clamps the lower end of the filter to ensure its centered placement. And the first spheres of the upper ball bearing seat rollingly contact the upper end of the filter, providing lateral limit and low-friction support.

[0021] During the process of placing the filter, in combination with the lowering rod and the elastic inner support part thereon, the filter can be accurately brought into the cleaning chamber and firmly clamped during the placement process. Ensure that the filter always maintains stable and efficient rotation during the cleaning process, and finally achieve the best cleaning effect. Brief Description of the Drawings

Detailed implementation manners

[0035] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] See Figures 1 - 6 As shown, a comprehensive cleaning device for an oil filter includes a cleaning pool 1. In the cleaning pool 1, a plurality of cleaning chamber bodies 2 capable of accommodating the oil filter 3 are arranged in a matrix. Each cleaning chamber body 2 is provided with a dynamic cleaning mechanism 4. The dynamic cleaning mechanism 4 includes a rotating support assembly 41 for placing the oil filter 3 and a flushing assembly 42 for cleaning the oil filter 3. In the working state, the rotating support assembly 41 cooperates with the flushing assembly 42 to drive the oil filter 3 to rotate. The flushing assembly 42 has a water spraying channel 4211 arranged tangentially to the surface of the oil filter 3. When the water flow passes through the water spraying channel 4211 and acts on the surface of the oil filter 3, the oil filter 3 is in a self-rotating state under the action of the tangential force of the high-pressure water flow, so that the oil filter 3 is efficiently cleaned.

[0037] When comprehensively cleaning the oil filter 3, first, the operator or an automated device places the oil filters 3 to be cleaned one by one inside the respective cleaning chamber bodies 2 arranged in a matrix in the cleaning pool 1.

[0038] With the official start of the cleaning program, the high-pressure water flow acts on the surface of the oil filter 3 through the water spraying channel 4211. Since the direction of the water flow is tangential to the surface of the oil filter 3, the oil filter 3 starts to rotate self-rotationally under the action of the tangential force generated by the high-pressure water flow. That is, the oil filter 3 starts to rotate slowly and steadily on the rotating support assembly 41, making a continuous and uniform rotational movement, so that every part of the oil filter 3 can receive sufficient water flow impact and cleaning, ensuring a cleaning effect without dead angles.

[0039] The filter 3 rotates continuously under the impetus of high-pressure water flow. The water flow continuously flushes the surface of the filter 3, effectively removing pollutants such as dirt, impurities, and oil stains adhering to it. During the dynamic cleaning process of the filter 3, compared with the static cleaning process, the water flow not only directly removes the dirt on the surface of the filter 3, but also further helps to eject the fine particles and sediments deep in the micropores of the filter material through the centrifugal force formed by rotation. The effective cleaning of the deep structure of the filter 3 is realized, the cleaning efficiency and quality are improved, the filter 3 is restored to its best working state, the service life is extended, and the filtering performance is ensured.

[0040] With the continuous cleaning process, the filter 3 gradually returns to its original clean state under the continuous high-pressure water flow and self-rotation action. The dirt on the surface of the filter 3 gradually decreases until the expected cleaning standard is finally reached.

[0041] See Figures 4 - 10 As shown, the flushing assembly 42 includes a plate member 421 and a nozzle 422 provided on the plate member 421 that can clean the filter 3 from the outside to the inside. The plate member 421 has the water spraying channel 4211 opened in the tangential direction of the surface of the filter 3, and a plurality of nozzles 422 communicating with the water spraying channel 4211 are evenly distributed along the axis direction of the filter 3 on the plate member 421.

[0042] When the flushing assembly 42 is started, the high-pressure water flow passes through the water spraying channel 4211 on the plate member 421. As the high-pressure water flow sprays out from the nozzle 422 and acts on the surface of the filter 3, due to the fact that the direction of the water flow is tangential to the surface of the filter 3, the filter 3 starts to rotate self-driven under the action of the tangential force generated by the high-pressure water flow. This enables the water flow to not only directly impact the outer surface of the filter 3, but also help to eject the fine particles and sediments deep in the micropores of the filter material through the centrifugal force formed by rotation.

[0043] Due to the arrangement of a plurality of nozzles 422 on the plate member 421, it is ensured that the water flow can clean the filter 3 comprehensively from the outside to the inside without leaving any dead corners. Through the coordinated work of a plurality of nozzles 422 on the plate member 421, the filter 3 can be efficiently and thoroughly cleaned under the action of the high-pressure water flow. It is ensured that every part of the filter 3 can receive sufficient water flow impact, so as to achieve the best cleaning effect.

[0044] See Figures 4 - 10 As shown, a plurality of the plate members 421 are evenly distributed around the rotation axis direction of the filter 3 in the cleaning chamber 2. When the nozzles 422 on all the plate members 421 spray water simultaneously, the cleaning liquid around the filter 3 is in a swirling state, so that the filter 3 is in a self-rotating cleaning state in the cleaning liquid.

[0045] When the cleaning chamber 2 is filled with cleaning liquid, the cleaning liquid passes through the filter 3, and a number of plate members 421 evenly distributed around the axis of rotation of the filter 3 start to work. The spray nozzles 422 on each plate member 421 spray high-pressure water jets through the water spray channels 4211 facing the tangential direction of the surface of the filter 3. When the spray nozzles 422 on all the plate members 421 spray water simultaneously, the high-pressure water jets form a strong swirling state around the filter 3. The swirling causes the filter 3 to be in a self-rotating cleaning state in the cleaning liquid, ensuring that every part of it can be subjected to uniform and continuous water flow impact.

[0046] As the filter 3 continuously rotates by itself, the centrifugal force generated throws out the fine particles and sediments deep in the micropores of the filter media, enabling the cleaning liquid to clean every part of the filter 3. Since the spray nozzles 422 on multiple plate members 421 work together, the swirling flow formed can cover the filter 3 comprehensively without any dead corners, thus achieving an efficient and thorough cleaning effect. It ensures that every position of the filter 3 in the cleaning liquid can be fully cleaned, ultimately reaching the best cleaning state.

[0047] See Figures 4 - 10 As shown, each plate member 421 can rotate in the cleaning chamber 2 to adjust the orientation of the orifice of the water spray channel 4211 according to the size of the filter 3, and the rotation direction of the plate member 421 is perpendicular to the axis of rotation direction of the filter 3.

[0048] When starting the cleaning program, the automation system first adjusts the angles of the respective plate members 421 according to the specific size and shape of the filter 3 to be cleaned. By rotating the plate members 421, the orientation of the orifice of the water spray channel 4211 can be precisely changed to ensure that the high-pressure water jets can act on the surface of the filter 3 at the best angle. The spray nozzles 422 on all the plate members 421 spray high-pressure water jets simultaneously. Due to the angle adjustment of the plate members 421, the water flow can more effectively cover the entire surface of the filter 3.

[0049] As the filter 3 rotates by itself in the cleaning liquid, the adjusted water spray channels 4211 enable the water flow not only to directly impact the outer surface of the filter 3, but also to throw out the fine particles and sediments deep in the micropores of the filter media through the centrifugal force generated by the rotation. Through the flexible angle adjustment of the plate members 421, it is ensured that regardless of the size of the filter 3, a uniform and efficient cleaning effect can be achieved without any dead corners, thus reaching the best cleaning state.

[0050] See Figures 4 - 10 As shown, in the cleaning chamber 2, there are upper shaft connection parts 21 and lower shaft connection parts 22 for the upper and lower ends of all the plate members 421 to be rotatably connected respectively, and a synchronous drive structure 23 for driving all the plate members 421 to rotate is provided on the lower shaft connection part 22.

[0051] The angle between each of the said plate members 421 and the filter 3 is equal.

[0052] The synchronous drive structure 23 has synchronous wheels 231 connected to the lower ends of each plate member 421 and a drive belt 232 connected to all the synchronous wheels 231. When the drive belt 232 runs, the synchronous wheels 231 are all in a rotating state, enabling all the plate members 421 to adjust their angles relative to the filter 3 synchronously.

[0053] The synchronous drive structure 23 also has a rotary driver for driving the drive belt 232 to drive, and the rotary driver is not shown in the figure.

[0054] When the cleaning program is started, the rotary driver drives the drive belt 232 to run, causing all the synchronous wheels 231 to rotate simultaneously, thereby driving all the plate members 421 to adjust their angles relative to the filter 3 synchronously. Due to the synchronous operation of the synchronous drive structure 23 on all the plate members 421, the angle between each plate member 421 and the filter 3 always remains equal, ensuring that the water flow can evenly cover the entire surface of the filter 3.

[0055] Specifically, when the drive belt 232 runs, the synchronous wheels 231 start to rotate, prompting each plate member 421 to rotate around its axis joint, achieving precise adjustment of the orientation of the water spray channels 4211. All the plate members 421 can change their angles in a coordinated manner, enabling the high-pressure water flow to act on the surface of the filter 3 at the best angle, thereby causing the filter 3 to rotate by itself due to the swirling effect, ensuring an efficient and uniform cleaning effect.

[0056] See Figures 4 - 8 As shown, the flushing assembly 42 further includes a spray pipe 423 capable of cleaning the filter 3 from the inside out. A plurality of spray openings 4231 are evenly distributed along one side of the spray pipe 423 in the axial direction thereof and are opened towards the nozzle 422.

[0057] When the cleaning program is started, the high-pressure water flow passes through the inside of the spray pipe 423 and sprays out from all the spray openings 4231 towards the filter 3 for impact. During the process of flushing from the inside out, due to the self-rotation of the filter 3, it is ensured that the high-pressure water flow can cover all areas inside the filter 3, effectively removing dirt, impurities, and deposits adhering to the internal filter media.

[0058] Since the spray openings 4231 are evenly distributed along the axial direction of the spray pipe 423, the water flow can impact the inside of the filter 3 from different positions simultaneously, ensuring that there are no dead corners and high efficiency during the cleaning process. Finally, under the coordinated action of the spray pipe 423 and the nozzle 422, the inside and outside of the filter 3 are comprehensively and meticulously cleaned. As the cleaning liquid is discharged from the cleaning chamber body 2, the water flow sprayed by the spray pipe 423 and the nozzle 422 can thoroughly clean the filter 3.

[0059] See Figure 4 , Figure 11 and Figure 12 As shown, the rotary support assembly 41 includes a lower ball support 411 disposed at the bottom of the cleaning chamber 2. The lower ball support 411 has a fixed portion 4111 and a rotary portion 4112. A sponge clip 4113 into which the lower end of the filter 3 can be snapped is provided on the rotary portion 4112. When the filter 3 is affected by the swirling flow, the rotary portion 4112 drives the filter 3 to rotate together.

[0060] Before the start of the cleaning process, the operator or automated equipment places the filter 3 on the lower ball support 411 at the bottom of the cleaning chamber 2. That is, the lower end of the filter 3 is aligned and snapped into the sponge clip 4113 on the rotary portion 4112 to ensure that the filter 3 is stably and centrally placed. The sponge clip 4113 can not only provide stable support, but also ensure that the clamped part of the filter 3 can also contact the cleaning liquid infiltrated in the sponge clip 4113.

[0061] When the cleaning program is started, the high-pressure water flow impacts the surface of the filter 3 tangentially through the water spray channels 4211 on the plate member 421. Since the direction of the water flow is tangential to the surface of the filter 3, the filter 3 is subjected to a strong tangential force and begins to rotate by itself. At this time, since the lower end of the filter 3 is clamped in the sponge clip 4113 of the rotary portion 4112, the filter 3 starts to rotate due to the swirling flow, and the rotary portion 4112 also rotates synchronously. The rotary portion 4112 of the lower ball support 411 can drive the filter 3 to rotate smoothly and with low resistance. So that the filter 3 can rotate stably and continuously under the action of the high-pressure water flow, ensuring that every part can uniformly receive the impact and cleaning of the water flow, thereby achieving efficient cleaning without dead angles in all directions.

[0062] See Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, the rotary support assembly 41 further includes an upper ball support 412 disposed at the top of the cleaning chamber 2. The upper ball support 412 has a plurality of first spheres 4121 uniformly distributed around the rotation axis direction of the rotary portion 4112. Each of the first spheres 4121 can rollingly contact the outer side of the upper end of the filter 3.

[0063] When the filter 3 is completely placed in the cleaning chamber 2, all the first spheres 4121 keep rolling contact with the outer side of the upper end of the filter 3, realizing the lateral limit of the filter 3 and keeping the filter 3 coaxial with the rotary portion 4112.

[0064] When the cleaning program is started, the filter 3 starts to rotate by itself. At this time, the first spheres 4121 on the upper ball support 412 roll along with the rotation of the filter 3, providing stable and low-resistance support.

[0065] Each first sphere 4121 is evenly distributed and in close contact with the outer side of the upper end of the filter 3, ensuring that the filter 3 remains stable and centered during the entire rotation process, preventing any deviation or wobbling. It not only provides additional support but also further ensures that the filter 3 can rotate and clean itself smoothly, thus achieving an efficient and comprehensive cleaning effect.

[0066] See Figure 4 、 Figure 5 、 Figure 11 and Figure 12 As shown, each first sphere 4121 can move towards the rotation axis direction of the rotating part 4112. The upper ball support 412 also has a guide rail 4122 for each first sphere 4121 to move, and each of the guide rails 4122 is provided with a push rod 4123 capable of pushing the first sphere 4121 to move.

[0067] A spring 4124 capable of enabling the first sphere 4121 to adaptively contact the filter 3 is provided between each push rod 4123 and the cleaning chamber body 2.

[0068] Each guide rail 4122 is provided with a pressing driver capable of controlling the corresponding push rod 4123 to maintain the pressing state against the first sphere 4121 after the first sphere 4121 is in adaptive contact with the filter 3. The pressing driver is not shown in the figure.

[0069] When the filter 3 is placed in place, under the action of the spring 4124, the first sphere 4121 is in close contact with the upper end of the filter 3. To ensure that the first sphere 4121 continuously provides stable support during the entire cleaning process, once the first sphere 4121 is in adaptive contact with the filter 3, the pressing driver will control the corresponding push rod 4123 to maintain the pressing state against the first sphere 4121, preventing it from loosening or shifting. It not only ensures that the filter 3 always remains stable and centered during the self-rotation process but also can automatically adjust the support force according to the specific shape and size of the filter 3, providing the best contact and support effect.

[0070] See Figures 2 - 5 、 Figure 11 and Figure 12 As shown, directly above the lower ball support 411, there is a lowering rod 5 capable of accurately bringing the filter 3 into the cleaning chamber body 2. The lower end of the lowering rod 5 is provided with an elastic inner support portion 51 capable of adaptively clamping the upper end of the filter 3, and the elastic inner support portion 51 has a second sphere 511 capable of rolling contact with the inner side of the upper end of the filter 3.

[0071] The cleaning pool 1 is provided with a lifting driver for driving the lowering rod 5 to move up and down. The lifting driver is not shown in the figure.

[0072] A plurality of the elastic inner support portions 51 are evenly distributed along the circumferential direction of the lowering rod member 5, and each of the elastic inner support portions 51 has two second spheres 511 arranged one above the other.

[0073] Before the filter 3 is placed into the cleaning chamber 2, first, an operator sleevs the upper end of the filter 3 on the lower end of the lowering rod member 5. At this time, the upper end of the filter 3 is caught in each of the elastic inner support portions 51, that is, caught between every two second spheres 511, so that the filter 3 is clamped. Subsequently, the lowering rod member 5 descends, and the filter 3 is brought into the cleaning chamber 2 until the lower end of the filter 3 is caught in the sponge clamp 4113.

[0074] Subsequently, after the filter 3 is laterally limited by the first sphere 4121, the filter 3 is positioned in the cleaning chamber 2. Since the rotating portion 4112 can drive the filter 3 to rotate, and the first sphere 4121 and the second sphere 511 are in rolling contact, the filter 3 can rotate normally with reduced friction.

[0075] In the present invention, the high-pressure water flow is guided by the water spraying channel 4211 to act on the surface of the filter 3 in a tangential direction, so as to promote the cleaning liquid in the cleaning chamber 2 to form a swirling state, and the filter 3 rotates on its own on the rotating support assembly 41, ensuring comprehensive cleaning and using centrifugal force to remove deep dirt.

[0076] As the synchronous drive structure 23 adjusts the angle of the plate member 421 according to the size of the filter 3, it is ensured that the angle between each plate member 421 and the filter 3 is equal. The nozzles 422 on all the plate members 421 spray high-pressure water flow simultaneously to achieve a swirling effect and promote the filter 3 to rotate on its own. Combined with the inner side flushing of the spray pipe 423, the inside and outside of the filter 3 are comprehensively and carefully cleaned, restoring the best working state, extending the service life and ensuring the filtering performance, and the whole process is efficient without any cleaning dead angle.

[0077] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
