[0002] Filter cloth is a filter medium woven from natural or synthetic fibers. It is mainly used for air filtration and dust removal to purify the air and protect the environment.

[0003] As the core filtration element of solid-liquid separation equipment, the installation stability of filter cloth directly affects filtration efficiency and equipment operation safety. The existing filter cloth locking method mainly uses multiple sets of bolts to fix the edge of the filter cloth to the equipment frame. During disassembly and assembly, each bolt needs to be tightened one by one, which consumes a lot of time for each disassembly and assembly. Moreover, the bolts are in contact with the filtration environment for a long time and are prone to corrosion. Once corroded, they are difficult to disassemble and often need to be cut and replaced, which greatly increases maintenance costs. Utility Model Content

[0016] Example 1, such as Figure 1-5 As shown, a filter cloth locking structure includes a U-shaped mounting frame 1, which is made of 304 stainless steel and has a chrome-plated surface for rust prevention.

[0017] Reference Figure 3-5 As shown in this embodiment: an installation device 2 is provided between the inner walls of the two vertical ends and the inner wall of the horizontal end of the U-shaped mounting frame 1. The installation device 2 includes a U-shaped mounting groove 201 formed between the inner walls of the two vertical ends and the inner wall of the horizontal end of the U-shaped mounting frame 1. A U-shaped frame 202 is slidably inserted into the U-shaped mounting groove 201. A filter cloth body 203 is fixedly installed between the four inner walls of the U-shaped frame 202. Two U-shaped plates 204 are fixedly installed on one side surface of the U-shaped frame 202. A threaded rod 205 is rotatably connected between the inner walls of the two ends of one of the U-shaped plates 204. A rotating wheel 2 is fixedly installed at one end of the threaded rod 205. 06, a sliding rod 207 is fixedly installed between the inner walls of the two ends of another U-shaped plate 204. A T-shaped plate 208 is threadedly connected to the surface of the threaded rod 205. The T-shaped plate 208 is slidably connected to the sliding rod 207 via the threaded rod 205. An insertion rod 209 is fixedly installed on the surface of the T-shaped plate 208. An insertion hole 210 matching the insertion rod 209 is opened on the inner wall surface of one side of the U-shaped mounting groove 201. The inner wall of the U-shaped mounting groove 201 is covered with a polytetrafluoroethylene wear-resistant layer. The U-shaped frame 202 is made of ABS engineering plastic. The filter cloth body 203 is made of synthetic fiber. The threaded rod 205 is made of 45# steel with a pitch of 2mm and is galvanized for rust prevention.

[0018] Reference Figure 2-4 As shown in this embodiment: a blocking device 3 is provided between the inner walls of the two ends of the U-shaped mounting groove 201. The blocking device 3 includes a rotating shaft 31 rotatably connected between the inner walls of the two ends of the U-shaped mounting groove 201. A sealing plate 32 is fixedly installed on the outer wall surface of the rotating shaft 31. A mounting seat 4 is fixedly installed on one side surface of the sealing plate 32 and one side surface of the U-shaped mounting frame 1. Mounting holes are opened on the surfaces of the two mounting seats 4. An extension plate 33 is fixedly installed on the top surface of the U-shaped mounting frame 1. A bolt 34 is threadedly connected to the surface of the extension plate 33. A threaded hole 35 matching the bolt 34 is opened on the top surface of the sealing plate 32. The bolt 34 is equipped with a spring washer.

[0019] Working principle: When using this device, first align the pre-loaded filter cloth U-shaped frame 202 with the entrance of the U-shaped mounting groove 201, ensuring the edge of the U-shaped frame 202 fits against the inner wall of the U-shaped mounting groove 201; slowly push the U-shaped frame 202, allowing it to slide along the inner wall of the U-shaped mounting groove 201 until the left and right sides of the U-shaped frame 202 fit against the inner walls of the two vertical ends of the U-shaped mounting groove 201, confirming the U-shaped frame 202 is in place, and then rotate the U-shaped frame 202 clockwise. The rotating wheel 206 on one side drives the threaded rod 205 to rotate on the inner wall of the U-shaped plate 204. Since the T-shaped plate 208 is threadedly connected to the threaded rod 205 and is limited by the sliding rod 207, the rotation of the threaded rod 205 will cause the T-shaped plate 208 to slide. The insertion rod 209 on the surface of the T-shaped plate 208 will move together until the insertion rod 209 is inserted into the insertion hole 210. After the loop frame 202 is locked, the edge of the closing plate 32 is then held and rotated around the rotating shaft 31. Move the sealing plate 32 until it fits against the open end surface of the U-shaped mounting frame 1. During this process, pay attention to the position of the sealing plate 32 to ensure that its surface is aligned with the edge of the U-shaped mounting frame 1 to avoid misalignment and poor sealing. Next, align the bolt 34 on the surface of the extension plate 33 with the threaded hole 35 of the sealing plate 32 and use a wrench to turn the bolt 34 clockwise until it is tightened. The bolt 34 locks the sealing plate 32 in conjunction with the threaded hole 35, preventing the sealing plate 32 from rotating around the shaft 31 during filtration. At the same time, the spring washer on the bolt 34 can play an anti-loosening role to prevent the bolt 34 from loosening due to vibration. Finally, fix the entire filter cloth locking structure to the filter equipment, such as the solid-liquid separator or the preset bracket of the air purifier, through the mounting seat 4 on the surface of the U-shaped mounting frame 1 and the sealing plate 32. Tighten the external bolts one by one through the mounting holes on the surface of the mounting seat 4 to ensure that the whole device is not offset or shaken, providing a stable foundation for subsequent filtration operations.
