Description

Technical Field

[0001] This utility model relates to the field of spunlace filter cartridge technology, and in particular to a high-efficiency spunlace folded antistatic filter cartridge. Background Technology

[0002] Spunlace pleated filter cartridges are made by reinforcing and folding filter materials such as filter paper or filter cloth into a compact filter element structure through a spunlace process. This design not only increases the filtration area but also improves the filtration efficiency. In addition, spunlace pleated filter cartridges are specially treated to have good antistatic properties.

[0003] Traditional filter cartridges are often fixed to the frame by direct sleeve or bolt connection. Direct sleeve connection is prone to loosening during long-term use, resulting in a decrease in filter cartridge filtration efficiency. Bolted connection is inconvenient for disassembly, cleaning or replacement during daily maintenance. Therefore, we propose a high-efficiency hydroentangled pleated antistatic filter cartridge to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where filter cartridges are directly fitted onto the frame, which can easily become loose, and the bolt fixation makes it inconvenient to disassemble for cleaning or replacement during daily maintenance. Therefore, this invention proposes a high-efficiency hydroentangled folded antistatic filter cartridge.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency spunlace pleated antistatic filter cartridge includes an inner frame. A right fixing ring and a left fixing ring are symmetrically arranged on the outer wall of the inner frame. A single spunlace filter cartridge is disposed on the side of the right and left fixing rings that are close to each other, and the spunlace filter cartridge is sleeved on the outer wall of the inner frame. A positioning ring is threadedly connected to the outer wall of the inner frame on the side of the right fixing ring, and a limiting ring is slidably sleeved on the outer wall of the inner frame on the side of the left fixing ring. The filter cartridge further includes:

[0007] The positioning component is located on one side of the positioning ring and is used to position the water-jet filter cartridge.

[0008] The fixing component is located on one side of the limiting ring and is used to fix the water-jet filter cartridge.

[0009] In one possible design, the right and left fixing rings are each provided with a water-spun groove on their adjacent sides, and the two ends of the water-spun filter cartridge are respectively inserted into the corresponding water-spun grooves and engaged with the water-spun grooves.

[0010] In one possible design, the positioning component includes four positioning blocks, which are fixedly arranged at equal intervals on the side of the positioning ring near the right fixed ring. The right fixed ring has a positioning groove corresponding to the positioning block on the side near the positioning ring, and the four positioning blocks are inserted into the corresponding positioning groove.

[0011] In one possible design, the fixing component includes a compression ring slidably fitted onto an inner frame. A limiting ring has an annular groove on one side, and one end of the compression ring is inserted into and slidably connected to the annular groove. A rotating ring is fitted onto the outer wall of the inner frame on one side of the compression ring, and the rotating ring is rotatably connected to the compression ring. The inner frame has a notch and a limiting opening, and the notch and the limiting opening are connected. A limiting block is provided inside the rotating ring, and the limiting block slidably engages with the notch and is engaged with the limiting opening.

[0012] In one possible design, multiple springs are fixedly installed at equal intervals on one side of the inner wall of the annular groove. One end of each spring is fixedly connected to one side of the extrusion ring. The elastic force of the multiple springs causes the limiting ring to be extruded towards the left fixed ring, thereby extruding and fixing the spunlace filter cartridge connected to the left fixed ring, preventing it from sliding on the inner frame.

[0013] In one possible design, sealing rings are provided on the opposite sides of the right and left fixing rings, with the two sealing rings respectively fitting against one side of the corresponding positioning ring and limiting ring.

[0014] In this application, during installation, firstly, the positioning ring is threaded onto the inner frame. Then, both ends of the spunlace filter cartridge are inserted into the spunlace grooves on the right and left fixing rings, respectively, and engaged with the spunlace grooves to achieve initial fixation of the spunlace filter cartridge. Next, it is fitted onto the inner frame, and the positioning block in the positioning assembly cooperates with the positioning groove on the right fixing ring to achieve positioning and initial fixation of the spunlace filter cartridge on the inner frame. Then, the limiting ring is slidably fitted onto the inner frame, and the limiting ring is pressed against the left fixing ring to generate a certain compressive force on the spunlace filter cartridge, thereby achieving firm fixation of the filter cartridge.

[0015] Meanwhile, in order to provide extrusion force to the limiting ring, a rotating ring, an extrusion ring, and springs are used. Specifically, the rotating ring is fitted onto the inner frame. During the process, the limiting block on the rotating ring first slides into the notch on the inner frame. After moving to a certain position, the rotating ring is rotated, causing the limiting block to slide into the limiting opening, thereby fixing the position of the rotating ring on the inner frame. Since the extrusion ring is rotatably connected to the rotating ring, when the rotating ring is fitted onto the inner frame, the extrusion ring is also fitted onto the inner frame and contacts the limiting ring. Multiple springs are set between the limiting ring and the extrusion ring, so that the limiting ring and the extrusion ring are pushed away from each other by elastic force. The extrusion ring is limited by the position of the rotating ring and cannot move. Therefore, the limiting ring will move toward the spunlace filter cartridge, thereby extruding and fixing the spunlace filter cartridge.

[0016] During the filtration process, air or liquid is filtered through the spunlace filter cartridge. Due to the folded design of the filter cartridge, the filtration area is increased and the filtration efficiency is improved. At the same time, the filter cartridge material is specially treated to have anti-static properties, effectively avoiding static electricity accumulation and safety hazards. When the filter cartridge needs to be replaced, simply rotate the rotating ring to release the position restriction of the rotating ring, and then the corresponding accessories and spunlace filter cartridge can be loosened and removed, which is convenient and quick.

[0017] Beneficial effects: In this utility model, the high-efficiency spunlace folded antistatic filter cartridge avoids the loosening or wear that occurs in traditional filter cartridges during use through the positioning component, thereby improving the filtration efficiency of the filter cartridge;

[0018] In this utility model, the high-efficiency spunlace folded antistatic filter cartridge, through the fixing component, not only achieves stable fixing of the filter cartridge, but also facilitates installation and disassembly. Installation or disassembly can be completed without complicated tools or equipment, reducing installation costs and maintenance difficulties.

[0019] In this utility model, the high-efficiency spunlace folded antistatic filter cartridge has a fixed assembly in which the spring force keeps the limiting ring under a certain compressive force on the spunlace filter cartridge, thus ensuring the stability of the filter cartridge during long-term use.

[0020] In this invention, the positioning component avoids the loosening or wear that occurs in traditional filter cartridges during use, thereby improving the filtration efficiency of the filter cartridge. The fixing component not only achieves stable fixing of the filter cartridge, but also facilitates installation and disassembly. Installation or disassembly can be completed without complicated tools or equipment, reducing installation costs and maintenance difficulty. Furthermore, the elasticity of the internal spring ensures that the limiting ring always maintains a certain squeezing force on the water-jet filter cartridge, ensuring the stability of the filter cartridge during long-term use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: Refer to Figure 1-4 A filter cartridge includes an inner frame 1, with a right fixing ring 3 and a left fixing ring 4 symmetrically arranged on the outer wall of the inner frame 1. A spunlace filter cartridge 2 is disposed on the side of the right fixing ring 3 and the left fixing ring 4 that are close to each other, and the spunlace filter cartridge 2 is sleeved on the outer wall of the inner frame 1. To fix the position of the spunlace filter cartridge 2, a positioning ring 5 is threadedly connected to the outer wall of the inner frame 1 on the side of the right fixing ring 3, and a limiting ring 6 is slidably sleeved on the outer wall of the inner frame 1 on the side of the left fixing ring 4.

[0028] Furthermore, the filter cartridge in this embodiment also includes a positioning component and a fixing component. The positioning component is disposed on one side of the positioning ring 5 and is used to position the spunlace filter cartridge 2. The fixing component is disposed on one side of the limiting ring 6 and is used to fix the spunlace filter cartridge 2.

[0029] First, insert both ends of the spunlace filter cartridge 2 into the spunlace grooves 7 located on the adjacent sides of the right fixing ring 3 and the left fixing ring 4, respectively, and engage with the grooves 7 to initially fix the position of the spunlace filter cartridge 2. Then, rotate the positioning ring 5 to connect it to the outer wall of the inner frame 1 via threads, further fixing one end of the spunlace filter cartridge 2 using the positioning assembly. Next, slide the limiting ring 6 to one side of the left fixing ring 4, and fix the other end of the spunlace filter cartridge 2 using the fixing assembly.

[0030] The positioning assembly includes four positioning blocks 501, which are fixedly arranged at equal intervals on the side of the positioning ring 5 near the right fixing ring 3. Correspondingly, the right fixing ring 3 has a positioning groove 301 on the side near the positioning ring 5, corresponding to the positioning blocks 501. When the positioning ring 5 rotates onto the inner frame 1, the four positioning blocks 501 will insert into the corresponding positioning grooves 301, thereby achieving the positioning connection between the positioning ring 5 and one end of the spunlace filter cartridge 2.

[0031] The fixing component includes a compression ring 8, which is slidably fitted onto the inner frame 1. A limiting ring 6 has an annular groove 601 on one side, and one end of the compression ring 8 is inserted into and slidably connected to the annular groove 601. To drive the compression ring 8, a rotating ring 9 is fitted onto the outer wall of the inner frame 1 on one side of the compression ring 8, and the rotating ring 9 is rotatably connected to the compression ring 8. The inner frame 1 has a notch 101 and a limiting opening 102, which are connected. A limiting block 901 is provided inside the rotating ring 9, which slides with the notch 101 and engages with the limiting opening 102.

[0032] To achieve compression and fixation of the spunlace filter cartridge 2, multiple springs 10 are fixedly installed at equal intervals on one side of the inner wall of the annular groove 601, and one end of each spring 10 is fixedly connected to one side of the compression ring 8. Through the elastic force of the multiple springs 10, the limiting ring 6 is compressed against the left fixing ring 4, thereby compressing and fixing the spunlace filter cartridge 2 connected to the left fixing ring 4, preventing it from sliding on the inner frame 1.

[0033] This application can be used in the field of spunlace filter cartridge technology, or in other fields applicable to this application.
