Description

Technical Field

[0001] This invention relates to the field of filtration technology, specifically to a quick-release filtration device for a washing pump. Background Technology

[0002] Washing pumps are widely used in industrial cleaning, agricultural irrigation, household water purification systems, car washing, and chemical liquid transportation. During operation, impurities in the fluid (such as silt, particles, and fibers) can easily enter the pump body, leading to impeller wear, seal failure, or pipeline blockage, reducing pump efficiency and lifespan. Therefore, the filtration device becomes one of the key components of a washing pump. Quick-release filtration devices for washing pumps are a highly efficient solution developed to address the problems of cumbersome disassembly and inconvenient maintenance associated with traditional filters, and are widely used in industrial cleaning, agricultural irrigation, and household water purification. Traditional filters suffer from inefficiencies due to bolt fixing, poor sealing, and long downtime maintenance periods. The quick-release design, through snap / screw structure, self-sealing technology, and modular filter screens, allows for tool-free disassembly, improving maintenance convenience. Furthermore, the combination of corrosion-resistant materials and a visual window enhances durability and monitorability.

[0003] Existing quick-release filter devices for washing pumps require cleaning of the filter rods after a certain period of use to prevent solid particles from affecting the filtration effect. Furthermore, the cleaning process requires specialized tools, adding to the inconvenience of subsequent maintenance. Therefore, this does not meet the current requirements. To address this, we propose a quick-release filter device for washing pumps. Summary of the Invention

[0004] This invention provides a quick-release filter device for a washing pump, which allows the filter rod to be cleaned simply by pulling the fixed plate, eliminating the need for special tools. This solves the problem mentioned in the background art that after a certain period of use, the filter rod needs to be cleaned to prevent solid particles from affecting the filtration effect, and that special tools are required for cleaning, which adds trouble to subsequent maintenance.

[0005] The present invention provides the following technical solution: a quick-release filter device for a washing pump, comprising a device housing, an inlet provided on the upper side of the device housing, an outlet provided on the lower side of the device housing, a push slide plate slidably connected inside the device housing, a plurality of mounting plates rotatably connected on the push slide plate, the mounting plates being used to install filter rods, and the push slide plate having vertical sliding grooves and arc sliding grooves, the vertical sliding grooves and the arc sliding grooves being connected;

[0006] The mounting plate is provided with a sliding bar, which is used to slide in connection with the vertical sliding groove and the arc sliding groove. A control protrusion is provided on the lower side of the mounting plate.

[0007] As an optional solution for a quick-release filter device for a washing pump according to the present invention, a connecting rod is provided in the middle of the push slide, and a fixed plate is fixedly connected to the other end of the connecting rod. The fixed plate is located inside the housing of the device and is slidably connected to the inside of the housing of the device. A locking groove is provided on the upper side of the fixed plate.

[0008] As an optional solution for a quick-release filter device for a washing pump according to the present invention, wherein: a fixed tube is fixedly connected to the lower side of the fixed plate, a sliding rod is slidably connected inside the fixed tube, a first spring is provided inside the fixed tube, one end of the first spring abuts against the fixed plate, and the other end of the first spring abuts against a protrusion on the sliding rod.

[0009] As an optional solution of the quick-release filter device for a washing pump according to the present invention, the upper end of the sliding rod is rotatably connected to a locking block, which is used to slide with the locking groove.

[0010] As an optional solution for a quick-release filter device for a washing pump according to the present invention, a support plate is provided on the lower side of the fixed plate, the fixed tube passes through the support plate and is slidably connected to the support plate, and an abutment rod is fixedly connected in the middle of the support plate.

[0011] As an optional solution for a quick-release filter device for a washing pump according to the present invention, the lower end of the sliding rod is fixedly connected to an inner support plate, and a plurality of inner support blocks are slidably connected inside the inner support plate, the inner support blocks being used to support the interior of the support plate.

[0012] As an optional solution for a quick-release filter device for a washing pump according to the present invention, wherein: one end of the inner support block is fixedly connected to an abutting inclined block, the abutting inclined block is used to abut against the lower end of the abutting rod, a second spring is provided between the inner support block and the inner support plate, the second spring is located inside the inner support plate, and a protrusion is provided on one side of the abutting rod.

[0013] As an optional embodiment of the quick-release filter device for a washing pump according to the present invention, an abutment post is installed on one side of the inner support plate, and the abutment post is used to abut against the protrusion.

[0014] The present invention has the following beneficial effects:

[0015] 1. This washing pump uses a quick-release filter device. When the filter rod needs cleaning, the operator pulls the fixed plate to drive the connecting rod and push the sliding plate to move axially in sync, causing the entire filter module (including the mounting plate and filter rod) to be quickly pulled outwards along the inner side of the device housing, thus removing the filter assembly as a whole. Subsequently, by rotating the control protrusion at the bottom of the mounting plate, the sliding bar is triggered to rotate in the arc groove, releasing the locking state between the mounting plate and the push sliding plate. At this time, by continuing to pull the fixed plate outwards, the edge structure of the push sliding plate forms a dynamic scraping interface with the surface of the filter rod when it retracts independently. With the mechanical force of the sliding plate displacement, the particles attached to the filter rod are automatically scraped off, achieving efficient cleaning of the filter rod. At the same time, it avoids the risk of secondary contamination of the filter media during traditional disassembly. In addition, by removing the filter rod 41 from the equipment, the particles cleaned on the filter rod 41 can be more easily cleaned, preventing particles from falling into the interior of the device housing 1.

[0016] 2. The washing pump uses a quick-release filter device. With the help of the synergistic action of the anti-collision block and the anti-collision rod, when the anti-collision rod and the anti-collision block come into contact with each other and squeeze each other, the anti-collision block will push the inner support block to expand outward. Based on this design principle, under the interaction of the inner support block and the push slide, the filter rod can be firmly clamped between the two. In this way, when the push slide moves upward from the bottom of the filter rod, it can effectively remove the particles attached to the filter rod and further clean the surface of the filter rod 41.

[0017] Furthermore, during the second operation, when the inner support block is slid upwards from the bottom of the filter rod, the locking block can be rotated to allow it to slide smoothly into the locking groove. Subsequently, under the elastic restoring force of the first spring, the sliding rod will slide, driving the inner support plate and the inner support block to move synchronously until the inner support block and the push slide plate are on the same horizontal plane. At this time, the push slide plate and the inner support block cooperate closely to clamp the filter rod, thereby achieving a comprehensive cleaning of the filter rod surface.

[0018] 3. This washing pump uses a quick-release filter device. When the sliding disc and the inner support block slide along the filter rod from the bottom to the top, the coordinated movement between the two, under the precise cooperation of the protrusion and the contact post, cleverly triggers a subtle vibration between the inner support block and the filter rod. This innovative design not only achieves effective cleaning of the filter rod surface, but also further enhances the cleaning effect through vibration. During the vibration process, stubborn particles that were originally attached to the filter rod are effectively shaken off, making the cleanliness of the filter rod reach a new level and achieving a more thorough and deep surface cleaning.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-12 This invention discloses a quick-release filter device for a washing pump, including a device housing 1, as shown in the figure. Figure 1 As shown, the outer casing 1 of the device is provided with a door for opening and closing the outer casing 1. An inlet 11 is provided on the upper side of the outer casing 1, allowing unfiltered water to enter the device. An outlet 12 is provided at the lower part of the outer casing 1, allowing filtered water to flow out. A sliding push plate 2 is slidably connected inside the outer casing 1, and multiple mounting plates 23 are rotatably connected to the sliding push plate 2. The mounting plates 23 are used to mount filter rods 41. The design of the mounting plates 23 allows the mounting plates 23 to... The filter rod 41 can be installed on the upper part, so that the position of the filter rod 41 can be stabilized. This ensures that the filter rod 41 will not affect the filtration effect when filtering water. The design of the push slide 2 allows the push slide 2 to clean the particles attached to the filter rod 41 as it slides upward, so that the filter rod 41 does not need to be cleaned with special equipment, which can reduce the cleaning time of the filter rod 41 to a certain extent. The push slide 2 is provided with a vertical slide groove 21 and an arc slide groove 22, which are connected.

[0034] The mounting plate 23 is provided with a sliding bar 24, which is used to slide and connect with the vertical sliding groove 21 and the arc sliding groove 22. A control protrusion 212 is provided on the lower side of the mounting plate 23. Through the design of the vertical sliding groove 21, the arc sliding groove 22 and the sliding bar 24, the mounting plate 23 can be fixed inside the push sliding plate 2, thereby providing a stable mounting platform for the mounting plate 23. At the same time, the filter rod 41 can be threaded to the mounting plate 23. Through the threaded design, the filter rod 41 can be more stably fixed to the mounting plate 23. At the same time, through the design of the control protrusion 212, it is convenient to rotate the mounting plate 23 when it is necessary to detach the mounting plate 23 from the push sliding plate 2.

[0035] A connecting rod 25 is provided in the middle of the push slide 2. The other end of the connecting rod 25 is fixedly connected to a fixed plate 26. The fixed plate 26 is located inside the device housing 1 and is slidably connected to the inside of the device housing 1. Through the design of the connecting rod 25, the push slide 2 and the fixed plate 26 can be fixed together, so that the fixed plate 26 can drive the push slide 2 to slide upward together during the upward sliding process. A locking groove 27 is provided on the upper side of the fixed plate 26.

[0036] During use, the water source is connected to the inlet 11, and the outlet 12 is connected to the required device, so that the filtered water can be drawn out through the outlet 12. When the filter rod 41 inside the device needs to be cleaned after the device has been used for a period of time, simply open the device and pull the fixing plate 26, so that the fixing plate 26 can drive the push slide plate 2 to slide together through the connecting rod 25, so that the push slide plate 2 and the fixing plate 26 can be removed from the inside of the device housing 1, so that the mounting plate 23 on the push slide plate 2 and the filter rod 41 can be removed from the inside of the device housing 1. This design of quick disassembly of the filter rod 41 and removal of the filter rod 41 from the inside of the device housing 1 can facilitate the cleaning of the filter rod 41 and prevent the cleaned solid particles from being left inside the device housing 1, so that the filter rod 41 can be cleaned more thoroughly.

[0037] After removing the push slide 2, fixed plate 26, and filter rod 41 from the device housing 1, the mounting plates 23 are rotated by controlling the protrusion 212. This allows the mounting plates 23 to rotate together with the sliding strip 24, enabling the sliding strip 24 to slide within the arc groove 22. The sliding strip 24 then slides to the junction of the vertical groove 21 and the arc groove 22, allowing it to slide into the vertical groove 21. This releases the mounting plate 23 from the push slide 2, preventing it from sliding upwards with the push slide 2 when the fixed plate 26 is pulled to move the connecting rod 25 and the push slide 2 upwards. Simultaneously, the upward sliding of the push slide 2 cleans the surface of the filter rod 41.

[0038] It should be noted that the threaded connection between the filter rod 41 and the mounting plate 23 has a certain amount of space, so that when the mounting plate 23 is rotated by the control protrusion 212, the mounting plate 23 will not affect the filter rod 41 during the rotation process, thus preventing damage to the filter rod 41.

[0039] In this embodiment: by designing that the sliding plate 2 and the fixed plate 26 can slide together inside the device housing 1, when it is necessary to clean the filter rod 41, the fixed plate 26 can be pulled to drive the connecting rod 25, the sliding plate 2 and the mounting plate 23 to slide together into the device housing 1, so that the filter rod 41 can be quickly removed from the device housing 1; at the same time, by controlling the protrusion 212 to rotate the mounting plate 23, the mounting plate 23 can be released from the fixing between the mounting plate 2 and the sliding plate 2. Then, by continuing to pull the fixed plate 26 to drive the sliding plate 2 to slide together, the sliding plate 2 can clean the surface of the filter rod 41 during the sliding process, so that the particles on the filter rod 41 can be cleaned.

[0040] Example 2 aims to address the issue that filter rod 41 accumulates fixed particles during use, requiring specialized tools for subsequent cleaning and increasing cleaning time. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-12 A fixed tube 28 is fixedly connected to the lower side of the fixed plate 26. The design of the fixed connection between the fixed plate 26 and the fixed tube 28 allows the fixed tube 28 to slide upwards along with the fixed plate 26. A sliding rod 29 is slidably connected inside the fixed tube 28. A first spring 210 is installed inside the fixed tube 28. One end of the first spring 210 abuts against the fixed plate 26, and the other end of the first spring 210 abuts against the protrusion on the sliding rod 29. The protrusion on the sliding rod 29 allows the force of the first spring 210 to act on the sliding rod 29. The design of the first spring 210 provides a certain power to the sliding rod 29, so that when the restriction on the sliding rod 29 is released, the sliding rod 29 can slide under the action of the first spring 210.

[0041] The upper end of the sliding rod 29 is rotatably connected to a locking block 211. The locking block 211 is used to slide with the locking groove 27. Through the design of the locking block 211, the position of the sliding rod 29 can be restricted when the locking block 211 is in contact with the fixed plate 26. At this time, the first spring 210 is in a compressed state, preventing the sliding rod 29 from sliding under the action of the first spring 210. At the same time, the locking block 211 and the sliding rod 29 will not separate.

[0042] A support plate 4 is provided on the lower side of the fixed plate 26. The fixed tube 28 passes through the support plate 4 and is slidably connected to the support plate 4. An abutment rod 34 is fixedly connected in the middle of the support plate 4. Through the design of the support plate 4, one end of the filter rod 41 can be fixed, and a stable installation platform can be provided for the abutment rod 34.

[0043] The lower end of the sliding rod 29 is fixedly connected to the inner support plate 3. Multiple inner support blocks 31 are slidably connected inside the inner support plate 3. Through the design of the fixed connection between the sliding rod 29 and the inner support plate 3, the sliding rod 29 can drive the inner support plate 3 to slide upward together as the fixed plate 26 slides upward. This allows the inner support plate 3 to support the inside of the filter rod 41 with the inner support blocks 31. The inner support blocks 31 are used to support the inside of the support plate 4. Through the design of the inner support blocks 31, the inside of the filter rod 41 can be supported, so that the filter rod 41 can be cleaned more thoroughly when the sliding plate 2 is cleaning it.

[0044] One end of the inner support block 31 is fixedly connected to an abutting inclined block 32. The abutting inclined block 32 is used to abut against the lower end of the abutting rod 34. Through the design of the abutting inclined block 32 and the abutting rod 34 abutting against each other, during the process of abutting against the abutting rod 34, each abutting inclined block 32 can drive the inner support block 31 to expand outward, so that the inner support block 31 can support the interior of the filter rod 41. A second spring 33 is provided between the inner support block 31 and the inner support plate 3. The second spring 33 is located inside the inner support plate 3. Through the design of the second spring 33, it can provide power for the reset of the inner support block 31. A protrusion 35 is provided on one side of the abutting rod 34.

[0045] After removing the filter rod 41 from the inside of the device housing 1, when cleaning the filter rod 41, you can first pull the fixed plate 26 to drive the fixed tube 28, sliding rod 29 and inner support plate 3 to slide upward together. When the sliding rod 29 drives the inner support plate 3 to slide to the contact rod 34, the contact rod 34 can contact the contacting inclined block 32, so that each inner support block 31 can expand outward, thereby allowing the inner support block 31 to support the inside of the filter rod 41. This allows the pushing slide plate 2 to clean the surface of the filter rod 41 more thoroughly as it slides upward. When the inner support block 31 slides from the lower end of the filter rod 41 to the upper end of the filter rod 41, push the fixed plate 26 again to make the inner support block 31 slide back to the lower end of the filter rod 41. At this time, the inner support block 31 and the pushing slide plate 2 are on different horizontal planes.

[0046] It should be noted that during the sliding of the fixed plate 26, the position of the support plate 4 needs to be fixed. This design allows the fixed plate 26 to slide together with the push plate 2, the fixed tube 28, the sliding rod 29, the inner support plate 3, and the inner support block 31. At the same time, the support plate 4, the filter rod 41, and the contact rod 34 are stationary, allowing the push plate 2 and the inner support block 31 to slide from the lower end of the filter rod 41 to the upper end of the filter rod 41, thereby cleaning the surface of the filter rod 41.

[0047] When the inner support block 31 slides back to the lower end of the filter rod 41, the locking block 211 is rotated, causing the locking block 211 to slide into the locking groove 27. At the same time, under the action of the first spring 210, the sliding rod 29 can drive the inner support plate 3 to slide downward, so that the inner support block 31 can be on the same horizontal plane as the pushing slide plate 2. Through this design, the pushing slide plate 2 and the inner support block 31 clamp the filter rod 41, so that the pushing slide plate 2 and the inner support block 31 can better clean the particles attached to the surface of the filter rod 41 as they slide from the lower end of the filter rod 41 to the upper end of the filter rod 41.

[0048] In this embodiment: through the cooperation between the abutting inclined block 32 and the abutting rod 34, the abutting rod 34, during the process of abutting the abutting inclined block 32, causes the abutting inclined block 32 to expand outward from the inner support block 31. Through this design, the filter rod 41 can be clamped between the inner support block 31 and the pushing slide 2 under the cooperation of the inner support block 31 and the pushing slide 2. Through this design, the pushing slide 2 can clean the particles attached to the filter rod 41 during the process of sliding from the lower end of the filter rod 41 to the upper end of the filter rod 41, and further clean the surface of the filter rod 41.

[0049] Furthermore, when the inner support block 31 is slid from the lower end to the upper end of the filter rod 41 for the second time, the locking block 211 can be rotated, allowing the locking block 211 to slide into the locking groove 27. At the same time, under the action of the first spring 210, the sliding rod 29 can be driven to slide, so that the sliding rod 29 can drive the inner support plate 3 and the inner support block 31 to slide together, so that the inner support block 31 can be on the same horizontal plane as the pushing slide plate 2. This allows the pushing slide plate 2 to clamp the filter rod 41 between the inner support block 31, thereby cleaning the surface of the filter rod 41.

[0050] Example 3 aims to address the problem that, during the cleaning process of the sliding disc 2, particles attached to the filter rod 41 may be difficult to clean completely. This example is an improvement upon Examples 1 and 2. For details, please refer to... Figures 1-12 An abutment post 36 is installed on one side of the inner support plate 3. The abutment post 36 is used to abut against the protrusion 35. Through the cooperation between the abutment post 36 and the protrusion 35, the abutment rod 34 can vibrate when the abutment post 36 abuts against the protrusion 35.

[0051] As the inner support plate 3, inner support block 31, and abutting inclined block 32 slide upwards, the abutting column 36 slides upwards as well. The upward sliding of the abutting column 36 engages with the protrusion 35, causing the abutting rod 34 and inner support plate 3 to vibrate. The vibration of the abutting rod 34 causes the abutting inclined block 32 and inner support block 31 to vibrate together. Through this design, the vibration of the inner support block 31 allows the filter rod 41 to vibrate together during the cleaning process, making the particles attached to the filter rod 41 cleaner.

[0052] In this embodiment: during the process of pushing the slide plate 2 and the inner support block 31 to slide from the lower end of the filter rod 41 to the upper end of the filter rod 41, the inner support block 31 and the filter rod 41 can vibrate due to the cooperation between the protrusion block 35 and the abutment post 36. With this design, the filter rod 41 can vibrate while being cleaned, so that the particles attached to the filter rod 41 can be cleaned more thoroughly, and the surface of the filter rod 41 can be cleaned even more effectively.

[0053] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
