Technical Field

[0001] This utility model relates to the field of high-pressure pump filtration technology, and in particular to a water flow filtration device for a high-pressure pump inlet pipe. Background Technology

[0002] The main purpose of installing a water flow filter on the inlet pipe of a high-pressure pump is to intercept impurities such as sand, rust, and suspended solids in the water, preventing them from entering the high-pressure pump and causing damage to its internal components, thus ensuring the stable and efficient operation of the high-pressure pump equipment.

[0003] When a water flow filtration device is installed on the inlet pipe of a high-pressure pump, the filter element built into the device filters impurities in the high-pressure water flow after the pump starts, thus ensuring the purity of the water entering the pump and ensuring the pump's operating efficiency and safety. However, the filter element is prone to wear and damage after prolonged use, requiring replacement. Since the filtration device usually requires the use of wrenches and other tools to disassemble the bolts one by one, the time required to replace the filter element is extended, which is not conducive to reducing downtime during filter element replacement.

[0004] Therefore, this application provides a high-pressure pump inlet pipe water flow filtration device to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-pressure pump inlet pipe water flow filtration device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure pump inlet pipe water flow filtration device, comprising a filtration device body and a filter element, wherein the filter element is disposed inside the filtration device body, and further comprising: The quick-release assembly is located at the bottom of the filter device body. The quick-release assembly includes a sealing top cover connected to the bottom of the filter device body. A sealing bottom cover is provided at the bottom of the sealing top cover. Both sides of the outer surface of the sealing bottom cover are provided with snap-fit ​​blocks. The sealing bottom cover is snapped into the sealing top cover by the snap-fit ​​blocks. A sealing assembly, which is located inside the quick-release assembly and is used to prevent water leakage, includes a sealing groove formed on the sealing top cover and the sealing bottom cover on opposite sides, and a sealing gasket is provided inside the sealing groove.

[0007] Furthermore, a limiting plate is connected to the side of the sealing bottom cover near the sealing top cover, and the limiting plate is engaged with the sealing top cover.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the limiting plate contacts the groove first, which facilitates the quick alignment of the sealing top cover and the sealing bottom cover, thereby ensuring that the sealing top cover and the sealing bottom cover are aligned and reducing the risk of leakage caused by misalignment.

[0009] Furthermore, a push plate is connected to the top of the sealing top cover near the snap-fit ​​block, and the push plate has an arc-shaped structure with a high center and low sides.

[0010] The beneficial effects of adopting the above-mentioned further solution are: to achieve the locking of the sealing bottom cover and the sealing top cover, so that the two fit together more tightly and seal, which is conducive to further improving the sealing safety between the sealing top cover and the sealing bottom cover.

[0011] Furthermore, the sealing top cover, push plate, and snap-fit ​​block are all provided with snap-fit ​​grooves, and pins are inserted into the snap-fit ​​grooves. The snap-fit ​​block is snapped into the sealing top cover by the pins.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the pin fixes the angle of the snap-fit ​​block on the sealing top cover, ensuring that the snap-fit ​​block will not accidentally come off under high pressure, thus enhancing safety.

[0013] Furthermore, a sliding groove is provided on one end of the sealing bottom cover near the snap-fit ​​block, and a slider is slidably connected inside the sliding groove, the slider being connected to the snap-fit ​​block.

[0014] The beneficial effects of adopting the above-mentioned further solution are: ensuring the accuracy of the locking block's rotation on the sealing bottom cover; at the same time, the slider and the groove cooperate to limit the movement path of the locking block, prevent the locking block from deviating during rotation, reduce the friction during rotation, and ensure the stability of the locking block when rotating and moving on the sealing bottom cover.

[0015] Furthermore, the outer surface of the pin is provided with an anti-slip coating.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the anti-slip coating increases the friction between the pin and the locking groove, ensuring the stability of the pin inside the locking groove and reducing the risk of accidental detachment.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model, by setting up a quick-release component, allows the rotating snap-fit ​​block to align with the disassembly slot of the sealing top cover, pull the sealing bottom cover to separate from the sealing top cover, remove the old filter element from inside the filter device body, place the new filter element on top of the sealing bottom cover, push the sealing bottom cover and sealing top cover to close again, and the new filter element will be sent into the filter device body. Finally, rotate the snap-fit ​​block to re-engage with the sealing top cover, completing the fixation of the sealing top cover and sealing bottom cover, realizing the replacement of the filter element. This solves the problem of long filter element replacement time in traditional filter devices, improves the maintenance efficiency of the filter device body, reduces equipment downtime, and lowers maintenance costs.

[0018] 2. This utility model features a sealing component with sealing grooves on both the top and bottom sealing covers. The sealing gasket is placed inside the sealing grooves. When the top and bottom sealing covers are closed, they will press the sealing gasket together from different directions, ensuring that the sealing gasket fully fills the gap between them. This prevents high-pressure water from leaking from the interface, ensuring the stable operation of the high-pressure pump water inlet system and improving its safety. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a high-pressure pump inlet pipe water flow filtration device, including a filter device body 1 and a filter element 4, the filter element 4 being disposed inside the filter device body 1, and further including: like Figures 1-3 As shown, quick-release assembly 2 is placed at the bottom of filter device body 1. Quick-release assembly 2 includes a sealing top cover 21 connected to the bottom of filter device body 1. A sealing bottom cover 22 is provided at the bottom of the sealing top cover 21. Both sides of the outer surface of the sealing bottom cover 22 are provided with snap-fit ​​blocks 23. The sealing bottom cover 22 is snapped into the sealing top cover 21 through the snap-fit ​​blocks 23. like Figures 2-3 As shown, the sealing assembly 3 is located inside the quick-release assembly 2 and is used to prevent water leakage. The sealing assembly 3 includes a sealing groove 31 formed on the sealing top cover 21 and the sealing bottom cover 22, which are close to each other. A sealing gasket 32 ​​is provided inside the sealing groove 31. By installing the snap-fit ​​block 23 on the outside of the sealing bottom cover 22, when the filter element 4 needs to be replaced, the snap-fit ​​block 23 is rotated to align the snap-fit ​​block 23 with the disassembly slot on the sealing top cover 21. The sealing bottom cover 22 is pulled to separate it from the sealing top cover 21. Then, the filter element 4 inside the filter device body 1 is replaced. The new filter element 4 is placed on top of the sealing bottom cover 22, and the sealing bottom cover 22 and the sealing top cover 21 are pushed to close again. The filter element 4 is sent into the interior of the filter device body 1. The snap-fit ​​block 23 is then rotated again. The filter element 4 is replaced by re-engaging the top cover 21 with the bottom cover 22, thus facilitating quick replacement. This solves the problem that filter devices usually require the use of wrenches and other tools to remove bolts one by one, which prolongs the working time for replacing the filter element 4. It helps to improve the maintenance efficiency of the filter device body 1, reduce downtime, and lower maintenance costs. Furthermore, by opening the sealing groove 31 on the top cover 21 and the bottom cover 22, and placing the sealing gasket 32 ​​inside the sealing groove 31, when the top cover 21 and the bottom cover 22 are closed, they simultaneously squeeze the sealing gasket 32 ​​from different directions, causing the sealing gasket 32 ​​to fill the gap between the top cover 21 and the bottom cover 22, preventing high-pressure water from leaking from the interface and ensuring the stable operation and safety of the high-pressure pump water inlet system.

[0023] Furthermore, such as Figures 2-3As shown, a limiting plate 24 is connected to the side of the sealing bottom cover 22 near the sealing top cover 21. The limiting plate 24 is snapped into the sealing top cover 21. By welding the limiting plate 24 to the top of the sealing bottom cover 22 and opening a groove on the sealing top cover 21 that matches the limiting plate 24, the limiting plate 24 contacts the groove first during the installation of the sealing bottom cover 22, which facilitates quick alignment of the sealing top cover 21 and the sealing bottom cover 22, thereby ensuring that the sealing top cover 21 and the sealing bottom cover 22 are aligned and reducing the risk of leakage due to misalignment.

[0024] Furthermore, such as Figures 2-3 As shown, a push plate 25 is connected to the top of the sealing top cover 21 near the snap-fit ​​block 23. The push plate 25 has an arc-shaped structure with a high center and low sides. By welding the push plate 25 to the top of the sealing top cover 21, since the center of the push plate 25 is high, when the snap-fit ​​block 23 slides along the push plate 25, the push plate 25 pushes the snap-fit ​​block 23 up through its own inclined surface, thereby locking the sealing bottom cover 22 and the sealing top cover 21, making the two fit more tightly and sealing more effectively, which helps to further improve the sealing safety between the sealing top cover 21 and the sealing bottom cover 22.

[0025] Furthermore, such as Figures 2-3 As shown, the sealing top cover 21, push plate 25, and snap-fit ​​block 23 are all provided with snap-fit ​​grooves 27. A pin 26 is inserted into the inside of the snap-fit ​​groove 27. The snap-fit ​​block 23 is snapped into the sealing top cover 21 through the pin 26. By inserting the pin 26 into the inside of the snap-fit ​​groove 27, the pin 26 fixes the angle of the snap-fit ​​block 23 on the sealing top cover 21, ensuring that the snap-fit ​​block 23 will not accidentally come off under high pressure, thus enhancing safety.

[0026] Furthermore, such as Figures 3-4 As shown, a groove is provided on one end of the sealing bottom cover 22 near the snap-fit ​​block 23. A slider 28 is slidably connected inside the groove. The slider 28 is connected to the snap-fit ​​block 23. By welding the snap-fit ​​block 23 to the outside of the slider 28, the two snap-fit ​​blocks 23 are aligned. When one snap-fit ​​block 23 is rotated, the snap-fit ​​block 23 drives the other snap-fit ​​block 23 to rotate synchronously through the slider 28. This ensures the accuracy of the snap-fit ​​block 23's rotation on the sealing bottom cover 22. At the same time, the slider 28 and the groove cooperate to limit the movement path of the snap-fit ​​block 23, prevent the snap-fit ​​block 23 from deviating during rotation, and reduce the friction during rotation, ensuring the stability of the snap-fit ​​block 23 when rotating and moving on the sealing bottom cover 22.

[0027] Furthermore, such as Figure 4As shown, an anti-slip coating 29 is provided on the outer surface of the pin 26. By spraying the anti-slip coating 29 onto the outer surface of the pin 26, when the pin 26 is inserted into the slot 27, the anti-slip coating 29 increases the friction between the pin 26 and the slot 27, ensuring the stability of the pin 26 inside the slot 27 and reducing the risk of it accidentally falling off.

[0028] Working principle: such as Figures 1-4 As shown, the filter body 1 is installed on the inlet pipe of the high-pressure pump. When the high-pressure pump is started, the high-pressure water flows through the filter body 1, and the filter element 4 filters impurities. After the filter element 4 has been used for a long time and is worn or damaged, it needs to be replaced. At this time, rotate the locking block 23. The locking block 23 rotates on the sealing bottom cover 22 through the cooperation of the sliding groove and the slider 28, and aligns with the disassembly port on the sealing top cover 21. Pull the sealing bottom cover 22 to separate it from the sealing top cover 21, and remove the filter element 4 from the inside of the filter body 1 for replacement. At the same time, seal the inside of the sealing groove 31. After replacing the gasket 32, the sealing bottom cover 22 is reinstalled at the bottom of the sealing top cover 21. The limiting plate 24 first contacts the groove on the inner side of the sealing top cover 21 to align the sealing bottom cover 22 with the sealing top cover 21 and prevent displacement. The sealing bottom cover 22 is then pushed, and the snap-fit ​​block 23 passes through the disassembly port on the sealing top cover 21. The snap-fit ​​block 23 is pushed to rotate along the push plate 25. The push plate 25 lifts the snap-fit ​​block 23 through its own inclined surface. The snap-fit ​​block 23 drives the sealing bottom cover 22 to move upward and cooperates with the sealing top cover 21 to squeeze the sealing gasket 32, so that the sealing gasket 32 ​​seals the gap between the two.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
