Description

Technical Field

[0001] This utility model relates to the field of filter cloth technology, and in particular to a composite PE polypropylene filter cloth. Background Technology

[0002] Filter cloth is a high-efficiency composite filter material specifically designed for plate filtration equipment. By combining the material advantages of polyethylene and polypropylene, it achieves characteristics such as high-precision filtration, chemical corrosion resistance, and long service life.

[0003] Utility model patent CN211536969U discloses a plate filter. The key technical features are as follows: It includes a fixed frame, which comprises a fixed rod. Side rods are fixedly mounted on both sides of the bottom of the fixed rod. Sliding grooves are formed on the corresponding positions of the side rods. A movable frame is disposed within the fixed frame. The movable frame includes an mounting rod. Sliding rods are fixedly mounted on both sides of the top of the mounting rod. A filter screen is disposed between the sliding rods. The top of the sliding rod is disposed within the sliding groove. A receiving groove is formed at the bottom of the fixed rod corresponding to the sliding rod. Limiting holes are formed at the bottom of the side rods. Fixing holes are formed at both ends of the mounting rod corresponding to the limiting holes. This design securely connects multiple plate filters together, increasing their stability during use and ensuring their filtration effect. Furthermore, when excessive dust accumulates on the filter screen, the movable frame can be directly pulled out for easy cleaning and maintenance of the filter screen, making the process convenient, quick, and reducing labor time while improving work efficiency.

[0004] Regarding the above-mentioned content, the following technical defects exist: The composite PE polypropylene filter cloth used in plate filters is a high-efficiency composite filter material specifically designed for plate filter equipment. By combining the material advantages of polyethylene and polypropylene, it can achieve high-precision filtration, chemical corrosion resistance, and long service life. In normal use, the plate filter is directly connected to the air duct to filter particles in the air. When the filter cloth becomes clogged after long-term use, it can be disassembled and replaced using clips. However, the process of installing the filter cloth on the plate filter using clips is relatively cumbersome. Although the fixation stability is good, the speed of fixing several clips one by one is slow, which affects the speed of filter cloth replacement and thus increases the downtime of the entire plate filter.

[0005] Therefore, it is necessary to provide a new type of composite PE polypropylene filter cloth to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where, during use, the plate filter is directly connected to the air duct to filter airborne particles. When the filter cloth becomes clogged after prolonged use, it can be disassembled and replaced using clips. However, installing the filter cloth on the plate filter using clips is a cumbersome process. Although the stability of the fastener is good, the speed of fastening several clips one by one is slow, which affects the speed of replacing the filter cloth and increases the downtime of the entire plate filter.

[0007] To solve the above-mentioned technical problems, this utility model provides a composite PE polypropylene filter cloth, comprising: a plate filter, wherein a filter cloth body is installed on the inner wall of the plate filter, and an adjustment mechanism is provided on one side of the plate filter. The adjustment mechanism includes an installation frame, which is slidably connected to one side of the plate filter. The inner wall of the installation frame is fixedly connected to the filter cloth body. Four adjustment holes are opened on the side of the installation frame. Connecting rods are slidably passed through the inner walls of three of the adjustment holes. One end of the arc surface of the connecting rod is fixedly connected to one side of the plate filter. A fixing rod is slidably passed through the inner wall of the other adjustment hole. One end of the arc surface of the fixing rod is fixedly connected to one side of the plate filter. A rotating rod is fixedly passed through the inner wall of the fixing rod. An adjustment block is rotatably connected to the arc surface of the rotating rod. Coil springs are sleeved at both ends of the arc surface of the rotating rod. The two ends of the arc surface of the coil springs are fixedly connected to the rotating rod and the adjustment block, respectively. A limit plate is slidably connected to the inner wall of the adjustment block. One side of the limit plate is fixedly connected to one side of the plate filter.

[0008] The effects achieved by the above components are as follows: The composite PE polypropylene filter cloth body used in the plate filter is a high-efficiency composite filter material specifically designed for plate filter equipment. By combining the material advantages of polyethylene and polypropylene, it can achieve high-precision filtration, chemical corrosion resistance, and long service life. Normally, the plate filter is directly connected to the air duct to filter particles in the air. When the filter cloth body becomes clogged after prolonged use, it can be disassembled and replaced using clips. However, installing the filter cloth body on the plate filter using clips is cumbersome. Although the stability is good, fixing several clips one by one is slow, affecting the speed of replacing the filter cloth body and increasing the downtime of the entire plate filter. In this case, an adjustment mechanism can be used instead of clips to install the filter cloth body on the plate filter. The adjustment mechanism can increase the speed of installing the filter cloth body, shorten the installation time, and simplify the installation steps.

[0009] Preferably, contact pads are fixedly connected to both sides of the limiting plate, and anti-slip textures are formed on the side of the contact pad away from the limiting plate.

[0010] The effect achieved by the above components is that the contact pad can increase the friction between the limiting plate and the inner wall of the adjusting block.

[0011] Preferably, the internal thread of the adjusting block has a positioning rod passing through it, and one end of the arc surface of the positioning rod is threadedly connected to the inner wall of the limiting plate.

[0012] The effect achieved by the above components is that the positioning rod can improve the stability of the connection between the adjusting block and the limiting plate.

[0013] Preferably, one end of the arc surface of the positioning rod is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the positioning rod.

[0014] The effect achieved by the above components is that the anti-slip groove can increase the friction on the surface of the positioning rod, thereby enabling the positioning rod to rotate faster.

[0015] Preferably, the rotating rod is a steel rod.

[0016] The effect achieved by the above components is that the steel rotating rod is relatively hard and not easily deformed even after long-term use.

[0017] Preferably, one end of the plate filter is provided with an auxiliary mechanism, which includes two connecting frames. Both connecting frames are fixedly connected to one end of the plate filter. A slider is slidably connected to the inner wall of one of the connecting frames. A hanging ring is fixedly connected to the side of the slider away from the plate filter. A limiting rod slides through the inner wall of the slider. The limiting rod slides through the other inner wall of the connecting frame. A spring is sleeved on one end of the arc surface of the limiting rod. The two ends of the spring are fixedly connected to the connecting frame and the limiting rod, respectively.

[0018] The effect achieved by the above components is that when connecting the plate filter to the air duct at a high position, the plate filter can be lifted by a crane in conjunction with an auxiliary mechanism, thereby facilitating subsequent installation tasks and improving the speed and efficiency of installing the plate filter on the air duct.

[0019] Preferably, the inner wall of the hanging ring is provided with a plurality of connecting grooves.

[0020] The effect achieved by the above components is that the connecting groove can increase the friction of the hanging ring surface.

[0021] Compared with related technologies, the composite PE polypropylene filter cloth provided by this utility model has the following beneficial effects:

[0022] By setting an adjustment mechanism, the filter cloth inside the plate filter can be fixed instead of using clips when replacing it. The adjustment mechanism can increase the speed of fixing the filter cloth, shorten the fixing time, simplify the steps, and thus reduce the downtime of the plate filter.

[0023] By setting up an auxiliary mechanism, when connecting the plate filter to the air duct at a high position, a crane can be connected to the auxiliary mechanism to facilitate the lifting of the entire plate filter. This improves the stability of the plate filter installation. Attached Figure Description

[0030] 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.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 The present invention provides a composite PE polypropylene filter cloth, comprising: a plate filter 1, a filter cloth body 4 installed on the inner wall of the plate filter 1, an adjustment mechanism 2 on one side of the plate filter 1, and an auxiliary mechanism 3 on one end of the plate filter 1.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The adjustment mechanism 2 includes a mounting frame 201, which is slidably connected to one side of the plate filter 1. The inner wall of the mounting frame 201 is fixedly connected to the filter cloth body 4. Four adjustment holes 202 are provided on the side of the mounting frame 201. Connecting rods 203 slide through the inner walls of three of the adjustment holes 202, with one end of the arc surface of the connecting rod 203 fixedly connected to one side of the plate filter 1. A fixing rod 204 slides through the inner wall of the other adjustment hole 202, with one end of the arc surface of the fixing rod 204 fixedly connected to one side of the plate filter 1. A rotating rod 205 is fixedly connected through the inner wall of the fixing rod 204, and an adjustment block 207 is rotatably connected to the arc surface of the rotating rod 205. A coil spring 206 is fitted at both ends of the arc surface. The two ends of the arc surface of the coil spring 206 are fixedly connected to the rotating rod 205 and the adjusting block 207, respectively. A limit plate 208 is slidably connected to the inner wall of the adjusting block 207. One side of the limit plate 208 is fixedly connected to one side of the plate filter 1. The composite PE polypropylene filter cloth body 4 used in the plate filter 1 is a high-efficiency composite filter material specifically designed for plate filter equipment. By combining the material advantages of polyethylene and polypropylene, it can achieve high-precision filtration, chemical corrosion resistance, and long service life. Normally, the plate filter 1 is directly connected to the air duct to filter particles in the air. When the filter cloth body 4 becomes clogged after long-term use, it can be... The filter cloth body 4 is disassembled and replaced using clips. However, installing the filter cloth body 4 onto the plate filter 1 using clips is a rather cumbersome process. Although the stability of the fastener is good, the speed of fixing several clips one by one is slow, which affects the speed of replacing the filter cloth body 4 and increases the downtime of the entire plate filter 1. In this case, the adjustment mechanism 2 can be used instead of clips to install the filter cloth body 4 onto the plate filter 1. By adjusting the mechanism 2, the speed of installing the filter cloth body 4 can be increased, the installation time can be shortened, and the installation steps can be simplified. Contact pads 210 are fixedly connected to both sides of the limiting plate 208. The side of the contact pad 210 away from the limiting plate 208 has anti-slip texture. The touch pad 210 can increase the friction between the limiting plate 208 and the inner wall of the adjusting block 207. The internal thread of the adjusting block 207 passes through the positioning rod 209. One end of the arc surface of the positioning rod 209 is threaded to the inner wall of the limiting plate 208. The positioning rod 209 can improve the stability of the connection between the adjusting block 207 and the limiting plate 208. Several anti-slip grooves 211 are opened at one end of the arc surface of the positioning rod 209. Several anti-slip grooves 211 are evenly distributed on the positioning rod 209. The anti-slip grooves 211 can increase the friction on the surface of the positioning rod 209, so that the positioning rod 209 can be rotated faster. The rotating rod 205 is a steel rod. The steel rotating rod 205 is relatively hard and is not easy to deform after long-term use.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The auxiliary mechanism 3 includes two connecting frames 31, both of which are fixedly connected to one end of the plate filter 1. A slider 32 is slidably connected to one inner wall of the connecting frame 31. A hanging ring 33 is fixedly connected to the side of the slider 32 away from the plate filter 1. A limiting rod 34 slides through the inner wall of the slider 32. The limiting rod 34 slides through the other inner wall of the connecting frame 31. A spring 35 is sleeved on one end of the arc surface of the limiting rod 34. The two ends of the spring 35 are fixedly connected to the connecting frame 31 and the limiting rod 34 respectively. When connecting the plate filter 1 to the air duct at a high place, the plate filter 1 can be lifted by a crane in conjunction with the auxiliary mechanism 3, which facilitates the subsequent installation task and improves the speed and efficiency of installing the plate filter 1 on the air duct. The inner wall of the hanging ring 33 is provided with several connecting grooves 36, which can improve the friction of the surface of the hanging ring 33.

[0035] The working principle of the composite PE polypropylene filter cloth provided by this utility model is as follows: Rotating the adjusting block 207 on the rotating rod 205 causes the adjusting block 207 to move and deform the coil spring 206. At this time, the adjusting hole 202 on the mounting frame 201 can be connected to the arc surface of the connecting rod 203 through the adjusting block 207 and the fixing rod 204. After the connection is completed, the adjusting block 207 can be released. The coil spring 206 will reset and drive the adjusting block 207 to move and press the adjusting block 207 towards the limiting plate 208, so that the inner wall of the adjusting block 207 contacts the limiting plate 208. At this time, the mounting frame 201 can be fixed on one side of the plate filter 1 by the contact between the adjusting block 207 and the limiting plate 208, thereby completing the replacement of the filter cloth body 4 installed in the mounting frame 201.

[0036] When the auxiliary mechanism 3 is needed to cooperate with the crane, the limit rod 34 can be pulled first. The movement of the limit rod 34 will cause the spring 35 to stretch. At this time, the slider 32 can be slid into the connecting frame 31. After the slider 32 is slid in, the limit rod 34 can be released. The spring 35 will return to its original position and cause the limit rod 34 to slide. The sliding of the limit rod 34 can be connected to the inner wall of the slider 32 through the connecting frame 31. At this time, the slider 32 can be fixed on the connecting frame 31. At this time, the hanging ring 33 can be fixed on the plate filter 1. The hanging ring 33 can be used to complete the task of lifting the plate filter 1.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
