Therefore, this utility model provides a water pump delivery type filter bag water treatment device to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water pump delivery type filter bag water treatment device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump conveying filter bag water treatment device, comprising a housing, an installation plate, a fixing plate, and a frame inside the housing. The fixing plates are symmetrically fixed on both sides of the inner wall of the housing. The filter bag is disposed inside the frame. The installation plate and the fixing plate are engaged by a positioning structure. An installation hole is provided through the installation plate. A positioning ring is fixedly provided on the top of the frame, wherein the positioning ring is engaged with the inner wall of the installation hole.

[0010] Preferably, the positioning structure includes a limiting rod slidably disposed inside the mounting plate, both ends of the limiting rod penetrating the mounting plate, and the lateral end of the limiting rod inserting into the fixing plate and engaging with its inner wall.

[0011] Preferably, the mounting plate has an internal mounting groove, and a reset elastic element is fixedly disposed between the outer surface of the limiting rod and the inner wall of the mounting groove.

[0012] Beneficial effects This utility model provides a water treatment device using a water pump-driven filter bag. Compared with the prior art, it has the following advantages: (1) The water pump conveying filter bag water treatment equipment replaces the traditional multi-bolt connection method by using the snap-fit ​​design of the positioning structure and the positioning ring. The mounting plate and the fixing plate are quickly snap-fitted and fixed by the limit rod and the reset elastic element. The frame is assembled by the "vertical insertion + horizontal rotation" of the positioning block and the positioning groove. When disassembling, it can be unlocked by simply operating in the reverse direction. There is no need to use tools to loosen the bolts one by one, which greatly shortens the time for filter bag replacement and equipment maintenance. It is especially suitable for high-frequency filter bag replacement scenarios and significantly improves the ease of operation.

[0013] (2) The water pump conveying filter bag water treatment equipment adopts a snap-fit ​​positioning structure, which reduces the hard friction loss between parts.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-6This utility model provides a technical solution: a water pump conveying filter bag water treatment device, including a housing 1, an installation plate 2, a fixing plate 3 and a frame 4 arranged inside the housing 1. The fixing plate 3 is symmetrically fixed on both sides of the inner wall of the housing 1. The fixing plate 3 is L-shaped, and its horizontal section provides a support reference for the installation plate 2. The vertical section is used to cooperate with the positioning structure 5 to fix the installation plate 2. The filter bag is arranged inside the frame 4. The installation plate 2 and the fixing plate 3 are connected by the positioning structure 5. The installation plate 2 has a through hole 6. The top of the frame 4 is fixedly provided with a positioning ring 7, wherein the positioning ring 7 is engaged with the inner wall of the installation hole 6.

[0019] Regarding the specific snap-fit ​​design between the positioning ring 7 and the mounting hole 6, positioning blocks 8, made of rubber, are symmetrically slidably mounted on the outer side of the positioning ring 7. A positioning groove 9 is connected to the inner wall of the mounting hole 6, and the positioning blocks 8 are inserted into the positioning groove 9 and snap-fitted against its inner surface. The snap-fit ​​between the positioning blocks 8 and the positioning groove 9 restricts the vertical displacement of the frame 4, preventing the frame from floating due to water pressure during operation. Furthermore, the rubber material has a certain elasticity, which can fill the gap between the positioning blocks 8 and the positioning groove 9, improving sealing performance and preventing unfiltered water from leaking through the gap. The positioning ring 7 also seals the side of the positioning groove 9.

[0020] For details regarding the specific structure of the housing 1, frame 4, and filter bag in this technical solution, please refer to Chinese Patent A Water Treatment Device for Convenient Filter Bag Replacement (Announcement No. CN209173493U, Announcement Date: 2019-07-30).

[0021] Regarding the structural design of the positioning slot 9, the positioning slot 9 consists of a vertical slot 901 and a horizontal slot 902, with the opposite sides of the vertical slot 901 and the horizontal slot 902 connected. The positioning block 8 is engaged with both the vertical slot 901 and the horizontal slot 902. The vertical slot 901 provides a vertical insertion channel for the positioning block 8, facilitating quick alignment of the frame 4 with the mounting hole 6. The horizontal slot 902 is used to receive the positioning block 8, achieving precise positioning of the frame 4 through a "vertical insertion + horizontal rotation" assembly method. Regarding the structural design of the positioning block 8, the side of the positioning block 8 relative to the transverse slot 902 is positioned as an inclined surface 801, which facilitates the positioning block 8 to slide into the transverse slot 902, reduces assembly resistance, and at the same time, the inclined structure can enhance the snap-fit ​​stability and prevent the positioning block from accidentally coming out; the height of the transverse slot 902 is less than the height of the positioning block 8; when the positioning block 8 slides into the interior of the transverse slot 902, it deforms due to the squeezing action, reducing its height, thereby causing the sealing ring 11 to move down a certain distance through the positioning rod 10, so that the sealing ring 11 is tightly attached to the surface of the mounting plate 2, improving the sealing performance.

[0022] As a further technical solution, a positioning rod 10 is fixedly installed on one side of the positioning block 8. The positioning rod 10 passes through the positioning ring 7 and extends to the top of the positioning ring 7 at one end. A sealing ring 11 is fixedly installed at the top of the positioning rod 10 to seal the opening of the vertical slot 901. A rubber ring is fixedly installed at the bottom of the sealing ring 11 to seal the opening of the vertical slot 901, prevent water from entering the interior of the positioning ring from the slot, and avoid corrosion or jamming of the positioning structure.

[0023] Regarding the design scheme between the positioning rod 10 and the positioning ring 7, the positioning rod 10 consists of a horizontal rod 1001 and a vertical rod 1002. The positioning ring 7 has a through-hole horizontal groove 701 and a vertical groove 702. The vertical rod 1002 is slidably disposed within the vertical groove 702, and the horizontal rod 1001 is disposed within the horizontal groove 701. The horizontal rod 1001 slides within the horizontal groove 701, providing guidance for the lateral movement of the positioning block 8; the vertical rod 1002 slides within the vertical groove 702, restricting the rotation of the positioning rod and ensuring operational stability. Furthermore, the inner diameter of the horizontal groove 701 is larger than the inner diameter of the horizontal rod 1001, reserving a certain amount of space for the overall movement of the positioning rod 10.

[0024] Regarding the design of the positioning structure 5, the positioning structure 5 includes a limiting rod 501 slidably disposed inside the mounting plate 2. The limiting rod 501 is made of flexible metal material that can be bent and recover its shape. After the filter bag is installed, the bottom of the sealing ring 11 abuts against the top of the limiting rod 501. Both ends of the limiting rod 501 penetrate the mounting plate 2, and the lateral end of the limiting rod 501 is inserted into the fixing plate 3 and engaged with its inner wall. The fixing plate 3 has a locking groove, and the end of the limiting rod 501 is inserted into the locking groove and engaged with its inner wall. Through the cooperation of the limiting rod 501 and the locking groove, the horizontal displacement of the mounting plate 2 is restricted, preventing the mounting plate 2 from shifting due to water flow impact. The mounting plate 2 has an installation groove 502 inside, and a reset elastic element 503 is fixedly disposed between the outer surface of the limiting rod 501 and the inner wall of the installation groove 502. The reset elastic element 503 is a spring, and its elastic coefficient can be set according to requirements.

[0025] After aligning the positioning block 8 with the vertical slot 901 and pressing it down to its end, the sealing ring 11 is in contact with the top of the mounting plate 2. Then, the sealing ring 11 is rotated synchronously, causing it to move the positioning block 8 into the horizontal slot 902 via the positioning rod 10. At the same time, under the action of the inclined surface 801, the inclined surface 801 squeezes the positioning block 8, compressing it. This causes the sealing ring 11 to move down a small distance via the positioning rod 10, making it fit more tightly against the surface of the mounting plate 2. Meanwhile, the bottom of the sealing ring 11 will squeeze the end of the limiting rod 501, causing the limiting rod 501 to move on the inner wall of the mounting plate 2 and engage with the snap-fit ​​groove on the fixing plate 3.
