Technical Field

[0001] The utility model relates to the technical field of filter cores, in particular to a PP filter membrane wound filter core. Background Technique

[0002] PP is polypropylene, which has the advantages of good chemical stability, acid and alkali resistance, etc. The structure of the PP filter membrane wound filter element is made by winding the PP filter membrane in a special way. Its working principle is that when liquid or gas passes through the filter element, impurities are intercepted by the filter membrane on one side of the filter element, while the clean fluid can pass through the filter membrane to the other side, thereby realizing the filtering function.

[0003] Generally, the filter element is placed inside the sleeve to filter sewage. When the filter element is used inside the sleeve, it will be soaked for a long time and is likely to adhere to the inside of the sleeve, making it inconvenient to take out. The existing ones cannot be ejected during disassembly and are prone to cracking. In view of this, we need a PP filter membrane wound filter element. Content of the Utility Model

[0004] The purpose of the utility model is to provide a PP filter membrane wound filter element to solve the problems raised in the above background technique.

Detailed Embodiment

[0022] As Figures 1-4As shown in the figure, the utility model provides a technical solution: a PP filter membrane winding filter element, which includes a sleeve 1 and a cover plate 2. The installation is carried out by pushing the cover plate 2 towards the sleeve 1. A filter element 3 is arranged inside the sleeve 1, and the installation is carried out by placing the filter element 3 inside the sleeve 1. A water inlet pipe 4 is arranged on the cover plate 2, and a water outlet pipe 5 is arranged on the outer wall of the sleeve 1. Mounting plates 6 are fixedly installed on both the sleeve 1 and the cover plate 2. The fixed installation of the cover plate 2 can be completed through the mounting plates 6 fixedly installed on the sleeve 1 and the cover plate 2. A jacking mechanism 7 is arranged on the sleeve 1 and the cover plate 2, and a stabilizing mechanism 8 is arranged on the jacking mechanism 7.

[0023] In this embodiment, a jacking mechanism 7 is arranged on the sleeve 1 and the cover plate 2. Through the elastic force of the bearing spring 73 in the jacking mechanism 7, the slider 71 can drive the push plate 72 on the outer wall to drive the filter element 3 to move out of the inside of the sleeve 1, which is convenient for removing the filter element 3. At the same time, the impurities attached to the inner wall of the sleeve 1 are removed by the push plate 72 to prevent it from affecting reuse.

[0024] In this embodiment, a stabilizing mechanism 8 is arranged on the jacking mechanism 7. When the bottom end of the extrusion rod 83 in the stabilizing mechanism 8 is extruded, the extrusion rod 83 can rotate. By driving the clamping blocks 84 at the end of the extrusion rod 83 to move towards the filter element 3, the outer wall of the filter element 3 can be clamped and fixed by the two clamping blocks 84, preventing the filter element 3 from shaking inside the sleeve 1 and affecting the use.

[0025] The above-mentioned jacking mechanism 7 includes a slider 71, which is slidably connected to the inner wall of the sleeve 1. A push plate 72 is fixedly installed on the outer wall of the slider 71, and the push plate 72 is in a fitting state with the inner wall of the sleeve 1. One end of the bearing spring 73 is fixedly connected to the outer wall of the slider 71, and the other end of the bearing spring 73 is fixedly connected to the inner wall of the sleeve 1. The bearing spring 73 is in a compressed state. Through the elastic force of the bearing spring 73, the slider 71 can drive the push plate 72 on the outer wall to drive the filter element 3 to move out of the inside of the sleeve 1, facilitating disassembly. A top rod 74 is fixedly installed on the inner wall of the cover plate 2, and the end of the top rod 74 is in a fitting state with the outer wall of the push plate 72. By driving the top rod 74 on the inner wall of the cover plate 2 to extrude the outer wall of the slider 71, the slider 71 can extrude the bearing spring 73 and move towards the inside of the sleeve 1.

[0026] The above-mentioned stabilizing mechanism 8 includes a rotating rod 81. The rotating rod 81 is rotatably connected to the inner wall of the push plate 72. One end of the outer wall of the rotating rod 81 is fixedly connected to one end of a torsion spring 82, and the other end of the torsion spring 82 is fixedly connected to the inner wall of the push plate 72. The elastic force of the torsion spring 82 can cause the rotating rod 81 to drive the extrusion rod 83 to rotate and reset, so that the extrusion rod 83 no longer clamps the filter element 3 for removal, facilitating the replacement of the filter element 3. An extrusion rod 83 is fixedly installed on the outer wall of the rotating rod 81. The extrusion rod 83 is arranged in a bent shape. By extruding the bottom end of the extrusion rod 83 through the inner wall of the sleeve 1, the extrusion rod 83 can be rotated. A clamping block 84 is fixedly installed at the end of the extrusion rod 83. By driving the clamping block 84 at the end by the extrusion rod 83 to move towards the filter element 3, the two clamping blocks 84 can clamp and fix the outer wall of the filter element 3, preventing the filter element 3 from shaking inside the sleeve 1 and affecting the use.

[0027] In this embodiment, the filter element 3 is placed inside the sleeve 1, and then the cover plate 2 is pushed towards the sleeve 1 for installation. The ejector rod 74 on the inner wall is driven by the cover plate 2 to extrude the outer wall of the slider 71, so that the slider 71 extrudes the bearing spring 73 and moves towards the inside of the sleeve 1. At the same time, the push plate 72 on the outer wall is driven by the slider 71 to move towards the inside of the sleeve 1, so that the filter element 3 moves into the inside of the sleeve 1 for installation. At this time, the inner wall of the sleeve 1 extrudes the bottom end of the extrusion rod 83, causing the extrusion rod 83 to rotate, and then the extrusion rod 83 drives the clamping block 84 at the end to move towards the filter element 3. The two clamping blocks 84 clamp and fix the outer wall of the filter element 3, preventing the filter element 3 from shaking inside the sleeve 1 and affecting the use. Finally, the cover plate 2 is fixedly installed through the mounting plate 6 fixedly installed on the sleeve 1 and the cover plate 2. When the internal filter element 3 needs to be disassembled, first, the mounting plate 6 is removed, and then the elastic force of the bearing spring 73 causes the slider 71 to drive the push plate 72 on the outer wall to drive the filter element 3 to move out of the inside of the sleeve 1. At the same time, the impurities attached to the inner wall of the sleeve 1 are removed by the push plate 72. At the same time, the elastic force of the torsion spring 82 causes the rotating rod 81 to drive the extrusion rod 83 to rotate and reset, so that the extrusion rod 83 no longer clamps the filter element 3 for removal, facilitating the replacement of the filter element 3.
