Description

Technical Field

[0001] This utility model relates to the field of wound filter technology, and more specifically, to a wound filter. Background Technology

[0002] A filter element is a core component with filtration and purification functions. Its role is to purify raw fluids and easily separate specific components from them. Currently, filter elements are widely used in the filtration of fluids such as oil, air, and water.

[0003] The existing wound filter cartridges still have the following problems when in use: 1. Most filter elements are usually installed inside the filter housing, and the filter housing must be removed before replacement. During repeated disassembly and assembly, the threads are prone to wear due to repeated tightening, which may lead to a decrease in sealing performance and cause leakage problems, affecting the normal operation and safety of the entire filtration system.

[0004] 2. During long-term use, scale, impurities, and other deposits easily accumulate on the inner wall of the filter housing, forming a large amount of deposits. These deposits are difficult to remove completely, which not only affects the cleanliness of the filter housing but may also reduce filtration efficiency and increase the difficulty of subsequent maintenance.

[0005] 3. The filter element is placed inside the filter housing and is constantly subjected to the impact of water flow. If the fixing structure is not stable enough, it is prone to displacement or shaking. This will interfere with the normal working position of the filter element, affect its filtration stability, and may shorten its service life.

[0006] In view of this, we propose a wound filter element. Utility Model Content

[0007] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a wound filter element to solve the technical problems mentioned in the background art.

[0008] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a wound filter element, comprising a filter housing, the filter housing having an outlet, a pressure cap having an inlet on the upper part of the filter housing, a wound filter element installed between the filter housing and the pressure cap, a fixed column having circumferentially evenly distributed fixing posts fixedly connected to the filter housing, a limit hook slidably connected to the fixing posts, the limit hook engaging with the filter housing and the pressure cap for limiting, a spring fixedly connected between the limit hook and the fixing posts, the pressure cap having a limit structure, and a cleaning positioning structure being provided inside the filter housing.

[0009] The present invention is further configured such that the limiting hook is fixedly connected to a fixing block, the fixing block is provided with a through groove, the pressure cap is slidably connected to a sliding ring, and the sliding ring is fixedly connected to a connecting frame distributed circumferentially at equal intervals.

[0010] The present invention is further configured such that the connecting frame is fixedly connected to a fixing rod, and the fixing rod is slidably connected to the through groove of an adjacent fixing block.

[0011] The present invention is further configured such that the limiting structure includes a rotating ring, the rotating ring is rotatably connected to the pressure cap, and the rotating ring is fixedly connected with spaced limiting members.

[0012] The present invention is further configured such that the limiting hook is provided with a groove, and the limiting member is limited and engaged with the groove of the limiting hook.

[0013] The present invention is further configured such that the cleaning positioning structure includes a fixing ring, the fixing ring is fixedly connected to the inner wall of the filter shell, the filter shell is slidably connected to a sliding member, and an elastic member is fixedly connected between the sliding member and the fixing ring.

[0014] The present invention is further configured such that a circumferentially distributed pressing block is slidably connected to the lower side of the sliding member, and a circumferentially distributed fixing plate is fixedly connected to the sliding member.

[0015] The present invention is further configured such that an elastic element is fixedly connected between the fixed plate and the extrusion block, and an extrusion ring is fixedly connected inside the filter shell.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a wound filter element, which has the following beneficial effects: 1. This utility model releases the limiting position by rotating the rotating ring, and then pressing the sliding ring compresses the spring, causing the limiting hook to separate from the filter shell and the pressure cap, thus achieving quick disassembly and installation of the pressure cap. This design eliminates the traditional threaded connection, effectively avoiding thread wear and sealing failure caused by repeated tightening, and greatly simplifying the maintenance process.

[0017] 2. After the cover is opened, the elastic element can automatically drive the sliding element to slide upward along the inner wall of the filter shell. This process can not only scrape off the stubborn dirt attached to the inner wall and achieve self-cleaning, but also push the old wound filter element out of the shell, solving the problems of difficult filter element removal and inconvenient internal cleaning of the filter shell.

[0018] 3. When a new filter element is installed, the downward movement of this invention pushes the sliding component and the squeezing block through the squeezing ring, causing multiple squeezing blocks to tighten radially and simultaneously, thus firmly clamping the filter element from the inside. This structure effectively suppresses the shaking of the filter element under the impact of water flow, improving its stability and reliability during operation. Attached Figure Description

[0024] Please see Figures 1-5A wound filter element includes a filter housing 1, a water outlet 2, a pressure cap 3 on the upper part of the filter housing 1, a water inlet 4 on the pressure cap 3, a wound filter element 5 installed between the filter housing 1 and the pressure cap 3, fixed posts 6 evenly distributed circumferentially on the filter housing 1, a limit hook 7 slidably connected to the fixed posts 6, the limit hook 7 limiting the filter housing 1 and the pressure cap 3, a spring 8 fixedly connected between the limit hook 7 and the fixed posts 6, a limit structure on the pressure cap 3, a cleaning and positioning structure inside the filter housing 1, a fixed block 9 fixedly connected to the limit hook 7, the fixed block 9 having a through groove, a sliding ring 10 slidably connected to the pressure cap 3, a connecting frame 11 evenly distributed circumferentially on the sliding ring 10, and a fixed rod 12 fixedly connected to the connecting frame 11, the fixed rod 12 slidably connected to the through groove of the adjacent fixed block 9.

[0025] Please see Figure 3 and Figure 4 The limiting structure includes a rotating ring 13, which is rotatably connected to the pressure cap 3. The rotating ring 13 is fixedly connected with spaced limiting members 14. The limiting hook 7 is provided with a groove, and the limiting member 14 is matched with the groove of the limiting hook 7 for limiting.

[0026] Please see Figure 2 and Figure 5 The cleaning and positioning structure includes a fixing ring 15, which is fixed to the inner wall of the filter housing 1. The filter housing 1 is slidably connected to a sliding member 16, and an elastic member 17 is fixedly connected between the sliding member 16 and the fixing ring 15. A circumferentially distributed pressing block 18 is slidably connected to the lower side of the sliding member 16. A circumferentially distributed fixing plate 19 is fixedly connected to the sliding member 16. An elastic member 20 is fixedly connected between the fixing plate 19 and the pressing block 18. A pressing ring 21 is fixedly connected inside the filter housing 1.

[0027] The working principle of this utility model: When using this device, connect the inlet 4 and outlet 2 to the pipeline. When it is necessary to replace the wound filter element 5, first rotate the rotating ring 13. The rotating ring 13 drives the limiting member 14 to move. The limiting member 14 loses contact with the groove of the limiting hook 7. Then press down the sliding ring 10. The sliding ring 10 drives the fixing rod 12 to move down through the connecting frame 11. The fixing rod 12 slides down along the through groove of the fixing block 9, so that the limiting hook 7 slides along the fixing post 6. The spring 8 is compressed, and the limiting hook 7 loses contact with the filter shell 1 and the pressure cover 3. Then remove the pressure cover 3 from the filter shell 1.

[0028] After the cap 3 separates from the filter housing 1, under the elastic force of the elastic element 17, the sliding element 16 moves upward along the inner wall of the filter housing 1. The sliding element 16 cleans the deposits on the inner wall of the filter housing 1 and brings the wound filter element 5 out of the filter housing 1, making it easy to replace the wound filter element 5.

[0029] After replacing the new wound filter element 5, the wound filter element 5 causes the sliding member 16 to move downward, the elastic member 17 is stretched, the sliding member 16 causes the extrusion block 18 to move downward, the extrusion block 18 is squeezed with the extrusion ring 21, causing the four extrusion blocks 18 to move closer to each other, the elastic member 20 is stretched, and the four extrusion blocks 18 clamp and fix the wound filter element 5, improving the stability of the wound filter element 5 in the filter shell 1.
