Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene filter cloth modules, and in particular to a polypropylene filter cloth module. Background Technology
[0002] Polypropylene filter cloth modules refer to filter cloth modules made of polypropylene material. They are commonly used in filtration systems to remove solid particles, impurities, or contaminants. Polypropylene is a common synthetic fiber that is widely used in industrial fields, especially in the filtration of liquids or gases, due to its excellent chemical stability, high temperature resistance, strong corrosion resistance, and good mechanical properties.
[0003] Existing technologies, such as the utility model patent with publication number CN213090072U, disclose a folded sandwich cloth filter module and air purifier with sterilization and disinfection functions. This patent uses a fixed frame and a filter element. The fixed frame is square, with one end open and the other end equipped with supporting ribs for airflow. The filter element is placed inside the fixed frame; it is a double-layer sandwich cloth filled with filter particles and folded repeatedly to form a pleated surface, which is the ventilation surface. The flat-plate filter module provided by this utility model, without changing the structure and function of existing air purifiers, fresh air systems, and air conditioning systems, can achieve highly efficient sterilization of bacteria and viruses simply by replacing the filter module.
[0004] In their daily work, the inventors discovered that in the prior art, the filter cloth module body is limited by fitting part of the filter cloth module body onto the arc surface of the support cylinder. Since this limiting method cannot effectively maintain the correct tension at all times, during the filtration process, the pressure of the liquid flow will cause the filter cloth module body to slide or shift within the support cylinder, or even wrinkle or loosen. This will reduce the effective filtration area of the filter cloth module body and affect the filtration efficiency.
[0005] Therefore, it is necessary to provide a new type of polypropylene filter cloth module to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this utility model is to solve the shortcomings of the prior art, where the filter cloth mold body in the prior art will slide or shift in the support cylinder during the filtration process, or even wrinkle or loosen, which will lead to a decrease in the effective filtration area of the filter cloth module body. Therefore, a polypropylene filter cloth module is proposed.
[0007] To solve the above-mentioned technical problems, this utility model provides a polypropylene filter cloth module, including: a support cylinder, a filter cloth module body slidably connected inside the support cylinder, a limiting structure on the arc surface of the support cylinder, the limiting structure including two fixing blocks, the two fixing blocks being fixedly connected to the support cylinder, two positioning posts being fixedly connected to both sides of each fixing block, a connecting plate slidably connected to the arc surface of each positioning post, two slots being formed inside the fixing blocks, an auxiliary groove and two limiting grooves being formed on the inner wall of the connecting plate, and a moving block being slidably connected to the inner wall of each limiting groove. Two movable blocks are fixedly connected to each other on their sides. A compression spring is provided between the movable block away from the support cylinder and the limiting groove. The two ends of the compression spring are fixedly connected to the movable block and the limiting groove, respectively. A spring is sleeved on the arc surface of the positioning post. The two ends of the spring are fixedly connected to the positioning post and the connecting plate, respectively. A connecting block is fixedly connected to the side of the connecting block away from the support cylinder. A locking block is fixedly connected to the side of the connecting block close to the fixed block. The locking block is slidably connected to the locking groove. The four connecting plates are grouped in pairs. A pressing plate is fixedly connected to the side of each pair of connecting plates that are close to each other.
[0008] The effect achieved by the above components is that when personnel need to place the filter cloth module body inside the support cylinder for use, they can move the two squeezing plates to make the locking block slide into the inner wall of the slot, thereby limiting the filter cloth module body and preventing the filter cloth module body from deforming inside the support cylinder, which would affect the filtration efficiency of the filter cloth module body.
[0009] Preferably, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the limiting rod is slidably connected to the moving block.
[0010] The effect achieved by the above components is that the limiting rod can limit the movement of the moving block and prevent the moving block from becoming misaligned during the sliding process on the inner wall of the limiting groove.
[0011] Preferably, protective pads are fixedly connected to the sides of the two extrusion plates that are close to each other, and the protective pads abut against the filter cloth module body.
[0012] The effect achieved by the above components is that the protective pad can protect the filter cloth module body and prevent the extrusion plate from directly contacting the filter cloth module body.
[0013] Preferably, a pull ring is fixedly connected to the side of the connecting block away from the fixed block, and the pull ring has a circular cross-section.
[0014] The effect achieved by the above components is that the pull ring allows personnel to easily move the connecting block, thereby improving the ease of operation for personnel.
[0015] Preferably, the arc surface of the pull ring is fixedly connected to an anti-slip sleeve, and the cross-section of the anti-slip sleeve is a hollow circle.
[0016] The effect achieved by the above-mentioned components is that the anti-slip sleeve can increase the friction between the person's hand and the pull ring, and can prevent the person from slipping when moving the pull ring.
[0017] Preferably, the positioning post is a stainless steel post.
[0018] The effect achieved by the above components is that the stainless steel column has high strength and good wear resistance, which can prevent the positioning column from deforming during short-term use.
[0019] Compared with related technologies, the polypropylene filter cloth module provided by this utility model has the following beneficial effects:
[0020] By setting a limiting structure, when personnel need to install the filter cloth module body inside the support cylinder for use, the limiting structure can limit the filter cloth module body, which can prevent the filter cloth module body from deforming inside the support cylinder and affecting the filtration efficiency of the filter cloth module body.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] Please see Figure 1 The present invention provides a polypropylene filter cloth module, comprising: a support cylinder 2, wherein a filter cloth module body 1 is slidably connected inside the support cylinder 2, and a limiting structure 3 is provided on the arc surface of the support cylinder 2.
[0030] In the embodiments of this utility model, please refer to Figures 2 to 5The limiting structure 3 includes two fixing blocks 301, which are fixedly connected to the support cylinder 2. Two positioning posts 303 are fixedly connected to both sides of each fixing block 301. A connecting plate 316 is slidably connected to the arc surfaces of the two positioning posts 303. Two slots 302 are formed inside the fixing blocks 301. An auxiliary groove 305 and two limiting grooves 306 are formed on the inner wall of the connecting plate 316. Moving blocks 308 are slidably connected to the inner walls of the limiting grooves 306. A connecting block 310 is fixedly connected to the side of the two moving blocks 308 closest to each other, and a connecting block 310 is fixedly connected to the side of the moving blocks 308 away from the support cylinder 2. A compression spring 309 is provided between 06. The two ends of the compression spring 309 are fixedly connected to the moving block 308 and the limiting groove 306 respectively. A spring 304 is sleeved on the arc surface of the positioning post 303. The two ends of the spring 304 are fixedly connected to the positioning post 303 and the connecting plate 316 respectively. A connecting block 311 is fixedly connected to the side of the connecting block 310 away from the support cylinder 2. A locking block 317 is fixedly connected to the side of the connecting block 311 close to the fixing block 301. The locking block 317 is slidably connected to the locking groove 302. The four connecting plates 316 are in pairs. A pressing plate 314 is fixedly connected to the side of each pair of connecting plates 316 that are close to each other. When personnel need to place the filter cloth module body 1 inside the support cylinder 2 for use, they can move the two extrusion plates 314 to slide the locking block 317 into the inner wall of the locking groove 302, thereby limiting the filter cloth module body 1 and preventing deformation of the filter cloth module body 1 inside the support cylinder 2, which would affect the filtration efficiency of the filter cloth module body 1. The inner wall of the limiting groove 306 is fixedly connected to the limiting rod 307, which is slidably connected to the moving block 308. The limiting rod 307 can limit the moving block 308 and prevent the moving block 308 from being misaligned during sliding on the inner wall of the limiting groove 306. Protective pads 315 are fixedly connected to the side of the two extrusion plates 314 that are close to each other, and the protective pads 315 abut against the filter cloth module body 1. The protective pad 315 protects the filter cloth module body 1, preventing direct contact between the extrusion plate 314 and the filter cloth module body 1. A pull ring 312 is fixedly connected to the side of the connecting block 311 away from the fixing block 301. The pull ring 312 has a circular cross-section. The pull ring 312 facilitates movement of the connecting block 311, improving operational convenience. An anti-slip sleeve 313 is fixedly connected to the arc surface of the pull ring 312. The anti-slip sleeve 313 has a hollow circular cross-section. The anti-slip sleeve 313 increases the friction between the user's hand and the pull ring 312, preventing slippage during movement. The positioning post 303 is made of stainless steel. Stainless steel posts have high strength and good wear resistance, preventing deformation of the positioning post 303 during short-term use.
[0031] The working principle of the polypropylene filter cloth module provided by this utility model is as follows: When personnel need to install the filter cloth module body 1 inside the support cylinder 2, they can first move the filter cloth module body 1 inside the support cylinder 2, and move one end of the filter cloth module body 1 to the side where the support cylinder 2 and the two extrusion plates 314 are close to each other. Then, the personnel move the two extrusion plates 314, causing them to move closer to the filter cloth module body 1. The extrusion plates 314 drive the two connecting plates 316 and the protective pad 315 to move closer to the filter cloth module body 1. The protective pad 315 can protect the filter cloth module body 1 and prevent the extrusion plates 314 from colliding with the filter cloth module. The main body 1 makes direct contact, and then the connecting plate 316 drives the two springs 304 to stretch. The connecting plate 316 also drives the two moving blocks 308, the two limiting rods 307, and the two compression springs 309 to move towards the fixed block 301. The limiting rods 307 can limit the moving blocks 308 to prevent them from misaligning during sliding on the inner wall of the limiting groove 306. Then, the two moving blocks 308 drive the connecting block 310 to move towards the fixed block 301. The connecting block 310 drives the connecting block 311 to move towards the fixed block 301. The connecting block 311 drives the locking block 317 and the pull ring 312 to move towards the fixed block. The pull ring 312 drives... The anti-slip sleeve 313 moves closer to the fixed block 301. The pull ring 312 facilitates movement of the connecting block 311, improving operational convenience. As the locking block 317 moves closer to the fixed block 301, its inclined surface abuts against the fixed block 301. The fixed block 301 then moves the locking block 317 away from the connecting plate 316. The locking block 317 then moves the connecting block 311 away from the connecting plate 316. The connecting block 311 then moves the connecting block 310 away from the connecting plate 316. The connecting block 310 then moves the two moving blocks 308 away from the connecting plate 316. The moving blocks 308 are positioned at the limit rod. The arc surface of 307 slides, and the moving block 308 also drives the compression spring 309 to rewind until the locking block 317 corresponds to the slot 302. At this time, the protective pad 315 abuts against the filter cloth module body 1. Then, the two compression springs 309 rebound, causing the locking block 317 to move closer to the slot 302 until the locking block 317 slides into the inner wall of the slot 302. The anti-slip sleeve 313 on the arc surface of the pull ring 312 can increase the friction between the person's hand and the pull ring 312, and can prevent the person from slipping during the movement of the pull ring 312. The positioning post 303 is a stainless steel post. Stainless steel posts have high strength and good wear resistance, which can prevent the positioning post 303 from deforming during short-term use.
