Description

Technical Field

[0001] This utility model relates to the field of fluid mechanical filtration technology, specifically to a diffusion filter connection device. Background Technology

[0002] A diffusion filter is a pipeline device that intercepts solid particles in a fluid through a porous medium. Its core consists of a metal filter screen or a sintered filter element. During operation, the fluid enters the housing through the connecting pipe, impurities are trapped by the filter components, and the purified fluid is discharged from the outlet. In scenarios such as semiconductor cleaning and food-grade liquid transportation, diffusion filters need to ensure airtightness while meeting the requirements of high-frequency cleaning.

[0003] The diffusion filter has a cleaning plate on its side wall. When cleaning the diffusion filter, the cleaning plate can be removed to clean the inside of the filter. However, existing diffusion filter cleaning plates are generally flanged to the filter housing. When cleaning or maintenance of the filter screen requires disassembly, the fixing bolts of the cleaning plate must be removed, and the cleaning plate must be manually moved to the ground. Large diffusion filter cleaning plates are heavy, requiring multiple people to work together after disassembly. Furthermore, manually moving the cleaning plate poses a certain risk of falling. When reinstalling the cleaning plate, manual assistance is needed to align the flange holes, making the construction difficult. Therefore, those skilled in the art provide a diffusion filter connection device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a diffusion filter connection device to solve the problems mentioned in the background section of the prior art.

[0005] This utility model provides the following technical solution: a diffusion filter connection device, including a housing and a filter assembly for intercepting impurities. The filter assembly is fixedly installed inside the housing. A connecting pipe is connected to the middle of one side of the housing. A fixing flange is fixedly connected to the end of the connecting pipe away from the housing. A connecting assembly is installed on one side of the fixing flange. A blocking plate is installed inside the connecting assembly. A limiting component for preventing the blocking plate from rotating is installed at the upper end of the connecting assembly.

[0006] As a preferred embodiment of the above technical solution, the connecting assembly includes a fixing plate, and two fixing plates are provided, which are symmetrically arranged. Both fixing plates are fixedly connected to the outer wall of the fixing flange. A rotating rod is rotatably connected between the two fixing plates. Two connecting plates are fixedly sleeved on the outside of the rotating rod, and a blocking plate is fixedly connected to one side of the two connecting plates.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes a mounting block and a toggle lever. The mounting block is fixedly connected to one side of the upper end face of the upper fixing plate, and the toggle lever is fixedly connected to the upper end face of the upper connecting plate.

[0008] As a preferred embodiment of the above technical solution, a sliding cavity is provided inside the mounting block. Multiple springs are fixedly connected to the inner wall of the sliding cavity near the fixed flange. The ends of the multiple springs away from the fixed flange are jointly fixedly connected to a sliding plate, which is slidably connected inside the sliding cavity.

[0009] As a preferred embodiment of the above technical solution, a locking block is fixedly connected to the end of the sliding plate away from the fixed flange. The locking block is wedge-shaped and penetrates the inner wall of the sliding cavity. The locking block is slidably disposed on the outside. An actuating port is provided on the inner wall of the sliding cavity near the housing. An actuating block is slidably connected in the actuating port. One end of the actuating block is fixedly connected to the side wall of the sliding plate.

[0010] As a preferred embodiment of the above technical solution, multiple bolts penetrate the edge of the blocking plate, all of which penetrate the fixing flange, and nuts are threaded onto the outside of each bolt. Connecting flanges are fixedly connected to the upper and lower ends of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a diffusion filter connection device, including a housing 1 and a filter assembly 2 for intercepting impurities. The filter assembly 2 is fixedly installed inside the housing 1. A connecting pipe 3 is connected to the middle of one side of the housing 1. A fixing flange 4 is fixedly connected to the end of the connecting pipe 3 away from the housing 1. A connecting assembly 5 is installed on one side of the fixing flange 4. A blocking plate 6 is installed inside the connecting assembly 5. A limiting assembly 7 for preventing the blocking plate 6 from rotating is installed at the upper end of the connecting assembly 5.

[0022] Furthermore, after disassembling bolts 8 and nuts 9, a handle is fixedly connected to one side of the blockage plate 6. The blockage plate 6 can be pulled open by using the handle in conjunction with the connecting component 5, thereby reducing the risks associated with manually moving the blockage plate 6 and greatly reducing the difficulty of restoring the blockage plate 6. This makes cleaning the filter component 2 inside the housing 1 easier. After the blockage plate 6 is opened, the limiting component 7 can automatically limit the blockage plate 6 to ensure that the blockage plate 6 is stably stopped after opening, preventing the blockage plate 6 from being accidentally closed by the staff during maintenance. This provides a stable working space for maintenance personnel and significantly improves the operational convenience and safety during equipment maintenance.

[0023] It is worth noting that filter component 2 is existing technology, mainly composed of double-layer large-opening filter screens. It is usually made of stainless steel to trap impurities. Built-in fluid balance blades or guide plates evenly distribute the flow rate to eliminate turbulence, and can integrate magnets to adsorb iron particles. When working, the fluid enters the outside of the filter screen from the inlet, and impurities are blocked on the surface of the filter screen. The clean medium flows into the interior through the mesh and then flows out from the outlet. This will not be elaborated further here.

[0024] As one implementation method in this embodiment, please refer to Figures 2-3As shown, the connecting assembly 5 includes a fixing plate 501. There are two fixing plates 501, and the two fixing plates 501 are arranged symmetrically. Both fixing plates 501 are fixedly connected to the outer wall of the fixing flange 4. A rotating rod 502 is rotatably connected between the two fixing plates 501. Two connecting plates 503 are fixedly sleeved on the outside of the rotating rod 502. A blocking plate 6 is fixedly connected to one side of the two connecting plates 503.

[0025] Furthermore, by pulling the blocking plate 6, the connecting plate 503 can rotate around the rotating rod 502 as the axis, thereby opening and closing the blocking plate 6. This reduces the risk of manually handling the blocking plate 6 and greatly reduces the difficulty of restoring the blocking plate 6, making it easier to clean the filter assembly 2 inside the housing 1.

[0026] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the limiting component 7 includes a mounting block 701 and a toggle lever 702. The mounting block 701 is fixedly connected to one side of the upper end face of the fixing plate 501 at the upper position, and the toggle lever 702 is fixedly connected to the upper end face of the connecting plate 503 at the upper position.

[0027] The mounting block 701 has a sliding cavity 703. Multiple springs 704 are fixedly connected to the inner wall of the sliding cavity 703 near the fixed flange 4. The ends of the multiple springs 704 away from the fixed flange 4 are fixedly connected to a sliding plate 705. The sliding plate 705 is slidably connected in the sliding cavity 703.

[0028] A locking block 706 is fixedly connected to one end of the sliding plate 705 away from the fixed flange 4. The locking block 706 is wedge-shaped and penetrates the inner wall of the sliding cavity 703. The locking block 706 is slidably disposed on the outside. An actuating port 707 is provided on the inner wall of the sliding cavity 703 near the housing 1. An actuating block 708 is slidably connected in the actuating port 707. One end of the actuating block 708 is fixedly connected to the side wall of the sliding plate 705.

[0029] Furthermore, when the blocking plate 6 rotates, the actuating rod 702 at the upper end of the connecting plate 503 moves along the rotation path. When the side wall of the actuating rod 702 contacts the inclined surface of the locking block 706, it pushes the sliding plate 705 to compress the spring 704. When the actuating rod 702 passes the apex of the locking block 706, the spring 704 resets and releases its elastic force. The spring 704 pushes the locking block 706 to move to the other side of the actuating rod 702. The vertical surface on one side of the locking block 706 limits the actuating rod 702, forming a mechanical self-lock. The limiting component 7 can automatically limit the blocking plate 6, ensuring that the blocking plate 6 is stably stopped after opening, preventing the blocking plate 6 from being accidentally closed during maintenance, and providing a stable working space for maintenance personnel. After maintenance is completed, the user pushes the actuating block 708, causing the locking block 706 to temporarily retract into the sliding cavity 703, releasing the locking block 706 from limiting the blocking plate 6, and then the blocking plate 6 can be closed, significantly improving the operational convenience and safety during equipment maintenance.

[0030] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4 As shown, multiple bolts 8 penetrate the edge of the blocking plate 6, and all of the multiple bolts 8 penetrate the fixing flange 4. Nuts 9 are threaded onto the outside of the multiple bolts 8. Connecting flanges 10 are fixedly connected to the upper and lower ends of the housing 1.

[0031] Furthermore, the through-type connection of bolts 8 and nuts 9, together with the fixed flange 4, forms a modular sealing system. The even distribution of stress between the plug plate 6 and the fixed flange 4 is achieved through the even distribution of multiple bolts 8, which not only ensures the sealing reliability under high pressure conditions, but also enables quick disassembly and maintenance through the standardized interface of the fixed flange 4. The connecting flange 10 is used to connect the shell 1, connecting the shell 1 to the designated water inlet and drainage points.

[0032] Working principle: When cleaning and maintenance of the filter assembly 2 inside the housing 1 is required, the bolts 8 and nuts 9 are removed, and then the blocking plate 6 is pulled, so that the connecting plate 503 can rotate around the rotating rod 502 as the axis, realizing the opening and closing of the blocking plate 6. This reduces the risk of manually handling the blocking plate 6 and greatly reduces the difficulty of restoring the blocking plate 6, making it easier to clean the filter assembly 2 inside the housing 1. When the blocking plate 6 rotates, the actuating rod 702 at the upper end of the connecting plate 503 moves along the rotation path. When the side wall of the actuating rod 702 contacts the inclined surface of the locking block 706, it pushes the sliding plate 705 to compress the spring 704. When the actuating rod 702 passes the top of the locking block 706, it springs back. Spring 704 returns to its original position and releases its elastic force. Spring 704 pushes the locking block 706 to move to the other side of the actuating lever 702. The vertical surface of one side of the locking block 706 limits the actuating lever 702, forming a mechanical self-lock. The limiting component 7 can automatically limit the blocking plate 6, ensuring that the blocking plate 6 is stably stopped after opening, preventing the blocking plate 6 from being accidentally closed by the staff during maintenance, and providing a stable working space for the maintenance personnel. After maintenance is completed, the user pushes the actuating block 708, causing the locking block 706 to temporarily retract into the sliding cavity 703, which releases the limiting of the blocking plate 6 by the locking block 706, and then the blocking plate 6 can be closed, significantly improving the convenience and safety of operation during equipment maintenance.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
