Description

Technical Field

[0001] The invention relates to the technical field of filtration, and in particular to a quick-detachable filtration device for a washing pump. Background Art

[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 mud, particles, fibers, etc.) can easily enter the pump body, causing impeller wear, seal failure or pipe blockage, reducing the efficiency and life of the pump. Therefore, the filter device has become one of the key components of the washing pump. The quick-release filter device for washing pumps is an efficient solution developed to solve the problems of cumbersome disassembly and inconvenient maintenance of traditional filters. It is widely used in industrial cleaning, agricultural irrigation and household water purification. Traditional filters have defects such as bolt fixation, poor sealing, and long downtime for maintenance, which affect their efficiency. The quick-release design uses a snap / screw structure, self-sealing technology and modular filter screen to achieve quick disassembly without tools, improving maintenance convenience. At the same time, the combination of corrosion-resistant materials and visual windows enhances durability and monitorability.

[0003] The existing quick-detachable filter device for a washing pump requires cleaning of the filter rod after a certain period of use to prevent solid particles from affecting the filtering effect of the filter rod. During the cleaning process, special tools need to be used for cleaning, which adds trouble to subsequent maintenance. Therefore, it does not meet the existing needs. We have proposed a quick-detachable filter device for a washing pump. Summary of the Invention

[0004] The present invention provides a quick-detachable filter device for a washing pump, which has the beneficial effect of cleaning the filter rod only by pulling the fixed plate, and does not require the use of special tools to clean the filter rod. It solves the problem mentioned in the above background technology that the filter rod needs to be cleaned after a certain period of use to prevent solid particles from affecting the filtering effect of the filter rod, and during the cleaning process, special tools need to be used for cleaning, which adds trouble to subsequent maintenance.

[0006] A sliding bar is provided on the mounting plate, and the sliding bar is used for sliding 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-detachable filter device for a washing pump described in the present invention, a connecting rod is provided in the middle of the push sliding plate, and the other end of the connecting rod is fixedly connected to a fixed plate, the fixed plate is located inside the device housing, and the fixed plate is slidably connected to the inside of the device housing, and a snap-fit groove is provided on the upper side of the fixed plate.

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

[0009] As an optional solution of the quick-detachable filter device for a washing pump described in the present invention, the upper end of the sliding rod is rotatably connected to a locking block, and the locking block is used to be slidably connected to the locking groove.

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

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

[0012] As an optional solution for a quick-detachable filter device for a washing pump described in the present invention, one end of the inner support block is fixedly connected to a resistance bevel block, the resistance bevel block is used to resist the lower end of the resistance 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 block is provided on one side of the resistance rod.

[0013] As an optional solution of the quick-detachable filter device for a washing pump described in the present invention, a resistance column is installed on one side of the inner support plate, and the resistance column is used to resist the protruding block.

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

[0015] 1. The washing pump uses a quick-release filter device. When the filter rod needs to be cleaned, the operator drives the connecting rod and the push slide to move axially synchronously by pulling the fixed disk outward, so that the entire filter module (including the mounting disk and the filter rod) is quickly pulled outward along the inside of the device housing to achieve the overall removal of the filter assembly. Subsequently, by rotating the control protrusion at the bottom of the mounting disk, the sliding bar is triggered to rotate in the arc groove, releasing the locking state of the mounting disk and the push slide. At this time, continue to pull the fixed disk outward, and when the push slide retreats alone, its edge structure forms a dynamic scraping interface with the surface of the filter rod. With the help of the mechanical force of the slide displacement, the particles attached to the filter rod are automatically scraped off, achieving efficient cleaning of the filter rod, while avoiding the risk of secondary contamination of the filter medium during the traditional disassembly process. At the same time, by removing the filter rod 41 from the device, the particles cleaned from the filter rod 41 can be more easily cleaned, which can prevent the particles from falling into the interior of the device housing 1.

[0016] 2. The quick-detachable filter device for the washing pump utilizes the synergistic effect of the oblique resistance block and the resistance rod. When the resistance rod and the oblique resistance block contact and squeeze each other, the oblique resistance block pushes the inner support block outward. Based on this design principle, the filter rod is firmly clamped between the inner support block and the push slide plate due to the interaction between the two. In this way, when the push slide plate moves upward from the bottom of the filter rod, it can effectively remove particulate matter attached to the filter rod, further cleaning the surface of the filter rod 41.

[0017] Not only that, in the second operation, when the inner support block is slid upward from the bottom of the filter rod, the locking block can be rotated to make it slide smoothly into the locking groove. Then, under the elastic restoring force of the first spring, the sliding rod will slide and drive the inner support plate and the inner support block to move synchronously until the inner support block and the pushing slide plate are on the same horizontal plane. At this time, the pushing slide plate and the inner support block work closely together to clamp the filter rod, thereby achieving comprehensive cleaning of the filter rod surface.

[0018] 3. The washing pump uses a quick-detachable filter device. When the sliding plate and the inner support block are pushed to slide along the filter rod from the lower end to the upper end, the coordinated movement between the two, with the precise cooperation of the protruding block and the resistance column, cleverly triggers the subtle vibration of the inner support block and the filter rod. This innovative design not only effectively cleans the surface of the filter rod, but also further enhances the cleaning effect through vibration. During the vibration process, the stubborn particles originally attached to the filter rod are effectively shaken off, which makes the cleanliness of the filter rod reach a new height and achieves more thorough and in-depth surface cleaning.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] For example 1, please refer to Figures 1-12 The present invention discloses a quick-detachable filter device for a washing pump, comprising a device housing 1, such as Figure 1 As shown, a closing door for opening and closing the device housing 1 is provided on the device housing 1, and a water inlet 11 is provided on the upper side of the device housing 1. Through the design of the water inlet 11, unfiltered water can enter the interior of the device through the water inlet 11. A water outlet 12 is provided below the device housing 1. Through the design of the water outlet 12, filtered water can flow out through the water outlet 12. A push slide 2 is slidably connected to the interior of the device housing 1, and a plurality of mounting discs 23 are rotatably connected to the push slide 2. The mounting disc 23 is used to install the filter rod 41. Through the design of the mounting disc 23, the mounting disc 23 can be installed. The filter rod 41 can be installed on the top, so that the position of the filter rod 41 can be stable, so that when the filter rod 41 is filtering water later, the water filtering effect will not be affected by the shaking of the filter rod 41. By pushing the design of the sliding plate 2, the particles attached to the filter rod 41 can be cleaned during the upward sliding of the sliding plate 2, so that the filter rod 41 does not need to be cleaned with special equipment, which can reduce the time for cleaning the filter rod 41 later. The sliding plate 2 is provided with a vertical slide groove 21 and an arc slide groove 22, and the vertical slide groove 21 and the arc slide groove 22 are connected;

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

[0035] A connecting rod 25 is provided in the middle of the push sliding plate 2, and 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 the fixed plate 26 is slidably connected to the inside of the device housing 1. Through the design of the connecting rod 25, the push sliding plate 2 and the fixed plate 26 can be fixed, so that the fixed plate 26 can drive the push sliding plate 2 to slide upward 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 water inlet 11, and the water outlet 12 is connected to the required device, so that the filtered water can be drawn out through the water outlet 12. When the device is used for a period of time and the filter rod 41 in the device needs to be cleaned, it is only necessary to open the device and pull the fixed plate 26 so that the fixed 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 fixed plate 26 can be taken out from the inside of the device shell 1, so that the mounting plate 23 on the push slide plate 2 and the filter rod 41 can be taken out from the inside of the device shell 1; the design of quickly disassembling the filter rod 41 and taking the filter rod 41 out of the device shell 1 can facilitate the cleaning of the filter rod 41 and prevent the cleaned solid particles from being left inside the device shell 1, so that the filter rod 41 can be cleaned more cleanly;

[0037] After the pushing slide 2, the fixed plate 26 and the filter rod 41 are taken out from the inside of the device housing 1, it is only necessary to rotate each mounting plate 23 by controlling the protrusion 212 so that the mounting plate 23 can drive the sliding bar 24 to rotate together, so that the sliding bar 24 can slide in the arc slide groove 22, so that the sliding bar 24 can slide to the intersection of the vertical slide groove 21 and the arc slide groove 22, so that the sliding bar 24 can slide into the vertical slide groove 21, so that the mounting plate 23 can be released from the fixation between the pushing slide plate 2, so that in the subsequent process of pulling the fixed plate 26 to drive the connecting rod 25 and the pushing slide plate 2 to slide upward together, the mounting plate 23 will not slide upward with the pushing slide plate 2, and at the same time, by pushing the slide plate 2 to slide upward, the surface of the filter rod 41 can be cleaned.

[0038] It should be noted that there is a certain amount of space left in the threaded connection between the filter rod 41 and the mounting disk 23, so that when the mounting disk 23 is subsequently rotated by controlling the protrusion 212, the mounting disk 23 will not affect the filter rod 41 during the rotation process, thereby preventing damage to the filter rod 41.

[0039] In this embodiment: by the design that the pushing slide plate 2 and the fixed plate 26 can slide together in the device housing 1, when the filter rod 41 needs to be cleaned later, the connecting rod 25, the pushing slide plate 2 and the mounting plate 23 can be driven to slide out into the interior of the device housing 1 by pulling the fixed plate 26, so that the filter rod 41 can be quickly taken out from the interior of the device housing 1; at the same time, the mounting plate 23 is rotated by the control protrusion 212 so that the mounting plate 23 can be released from the fixation between the pushing slide plate 2, and then the fixed plate 26 is continued to be pulled to drive the pushing slide plate 2 to slide together, so that the pushing slide plate 2 can clean the surface of the filter rod 41 during the sliding process, thereby cleaning the particles on the filter rod 41.

[0040] Example 2: This example is intended to solve the problem that some fixed particles will be attached to the filter rod 41 during use. In the subsequent cleaning process of the particles, special tools need to be used, which increases the cleaning time. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-12 The lower side of the fixed plate 26 is fixedly connected to a fixed tube 28. Through the design of the fixed connection between the fixed plate 26 and the fixed tube 28, the fixed plate 26 can drive the fixed tube 28 to slide upward during the upward sliding process. The interior of the fixed tube 28 is slidably connected to a sliding rod 29. A first spring 210 is provided inside the fixed tube 28. One end of the first spring 210 contacts the fixed plate 26, and the other end of the first spring 210 contacts the protrusion on the sliding rod 29. Through the design of the protrusion on the sliding rod 29, the force of the first spring 210 can act on the sliding rod 29. Through the design of the first spring 210, a certain power can be provided for the sliding rod 29, so that when the restriction on the sliding rod 29 is subsequently released, the sliding rod 29 can be driven to 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, which is used to be slidably connected to the locking groove 27. Through the design of the locking block 211, the locking block 211 can limit the position of the sliding rod 29 during the process of interference 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, and 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, a fixed tube 28 passes through the support plate 4, and the fixed tube 28 is slidingly connected to the support plate 4, and a resistance 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 at the same time, a stable installation platform can be provided for the resistance rod 34.

[0043] The lower end of the sliding rod 29 is fixedly connected to the inner support plate 3, and the inner sliding connection of the inner support plate 3 is multiple inner support blocks 31. 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 as the fixed plate 26 slides upward, so that the inner support plate 3 can 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 when the sliding plate 2 is pushed to clean the filter rod 41, the filter rod 41 can be cleaned more thoroughly.

[0044] One end of the inner support block 31 is fixedly connected to a conflicting inclined block 32, which is used to conflict with the lower end of the conflicting rod 34. Through the design of the mutual conflict between the conflicting inclined block 32 and the conflicting rod 34, when the conflicting inclined block 32 conflicts with the conflicting rod 34, each conflicting inclined block 32 can drive the inner support block 31 to expand outward under the interference of the conflicting rod 34, so that the inner support block 31 can support the inside of the filter rod 41. A second spring 33 is provided between the inner support block 31 and the inner support disk 3. The second spring 33 is located inside the inner support disk 3. Through the design of the second spring 33, it can provide power for the reset of the inner support block 31, and a protrusion block 35 is provided on one side of the conflicting rod 34.

[0045] When the filter rod 41 is taken out from the inside of the device shell 1, when the filter rod 41 needs to be cleaned, the fixed plate 26 can be directly pulled to drive the fixed tube 28, the sliding rod 29 and the inner support plate 3 to slide upward together, so that 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 contact 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, so that the surface of the filter rod 41 can be cleaned more thoroughly during the upward sliding process of the pushing slide plate 2. 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, the fixed plate 26 is pushed 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 at different horizontal planes.

[0046] It should be noted that, in the process of pulling the fixed plate 26 to slide, the position of the support plate 4 needs to be fixed. Through such a design, the fixed plate 26 can drive the sliding plate 2, the fixed tube 28, the sliding rod 29, the inner support plate 3 and the inner support block 31 to slide together during the sliding process. At the same time, the support plate 4, the filter rod 41 and the resistance rod 34 are in a stationary state, so that the sliding plate 2 and the inner support block 31 can slide from the lower end of the filter rod 41 to the upper end of the filter rod 41, thereby realizing the cleaning of 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 again, the locking block 211 is rotated at this time, so that the locking block 211 slides 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 in the same horizontal plane as the pushing slide plate 2. Through such a design, the filter rod 41 is clamped between the pushing slide plate 2 and the inner support block 31, 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 during the process of sliding from the lower end of the filter rod 41 to the upper end of the filter rod 41.

[0048] In this embodiment, the cooperation between the oblique block 32 and the oblique rod 34 enables the oblique block 32 to expand the inner support block 31 when the oblique rod 34 contacts the oblique block 32. With this design, the filter rod 41 can be clamped between the inner support block 31 and the push slide plate 2 under the cooperation between the inner support block 31 and the push slide plate 2. With this design, the push slide plate 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, thereby further cleaning the surface of the filter rod 41.

[0049] Not only that, when the inner support block 31 is slid from the lower end of the filter rod 41 to the upper end of the filter rod 41 for the second time, the locking block 211 can be rotated so that the locking block 211 can 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 in the same horizontal plane as the pushing slide plate 2, so that the pushing slide plate 2 can clamp the filter rod 41 between the inner support block 31, so that the surface of the filter rod 41 can be cleaned.

[0050] Example 3: This example is intended to promote the solution of the problem that it is difficult to clean the particles on the filter rod 41 when pushing the sliding plate 2 to clean the particles attached to the filter rod 41. This example is an improvement made on the basis of Example 1 and Example 2. For details, please refer to Figures 1-12 A resistance column 36 is installed on one side of the inner support plate 3, and the resistance column 36 is used to resist the protruding block 35. Through the cooperation between the resistance column 36 and the protruding block 35, when the resistance column 36 resists the protruding block 35, the resistance rod 34 can vibrate.

[0051] In the process of pulling the inner support plate 3, the inner support block 31 and the interference inclined block 32 to slide upward, the interference column 36 can be driven to slide upward together. The upward sliding of the interference column 36 can cooperate with the protruding block 35, so that the interference rod 34 and the inner support plate 3 vibrate. When the interference rod 34 vibrates, the interference inclined block 32 and the inner support block 31 vibrate together. Through such a design, the vibration of the inner support block 31 can make the filter rod 41 vibrate together during the process of cleaning the surface of the filter rod 41, so that the particles attached to the filter rod 41 can be cleaned more cleanly.

[0052] In this embodiment: in the process of pushing the sliding 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 cooperation between the protrusion block 35 and the interference column 36 allows the inner support block 31 and the filter rod 41 to vibrate. Through such a design, the filter rod 41 can be vibrated while being cleaned, so that the particles attached to the filter rod 41 can be cleaned more cleanly, and the surface of the filter rod 41 can be further cleaned.

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

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
