[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a device for quickly replacing filter cloth, comprising:

[0027] The quick-change assembly includes a base 101, an H-shaped support frame 102, a limiting rod 103, and a round tube 104. The H-shaped support frame 102 is fixedly connected to the base 101, and the limiting rod 103 is fixedly connected to the H-shaped support frame 102. The filter fan is movably placed in the gap between the limiting rods 103. The round tube 104 is fixedly connected to the base 101, and the bottom end of the filter fan is movably engaged in the round tube 104. The limiting rod 103 and the round tube 104 work together to make the filter fan form an inverted triangle shape.

[0028] The H-shaped support frame 102 provides a guarantee for the installation of the limiting rod 103. The gap between the limiting rods 103 is used to flexibly engage the filter fan, and the round tube 104 further engages the bottom of the filter fan.

[0029] The limiting rods 103 are equidistant from each other, and the circular tubes 104 are equidistant from each other;

[0030] The placement of these components ensures that multiple filter fans can be arranged at equal intervals.

[0031] The quick-change assembly also includes a guide cylinder 105 and a pull rod 106. The guide cylinder 105 is fixedly connected to the limit rod 103, and the pull rod 106 is movably inserted between the guide cylinders 105.

[0032] The guide cylinder 105 provides a guarantee for the movable connection of the pull rod 106, which is used to further limit the position of the filter fan.

[0033] The quick-change assembly also includes a diagonal reinforcing rod 107, which is fixedly connected between the base 101 and the H-shaped support frame 102.

[0034] The diagonal reinforcing rod 107 is used to further reinforce the connection between the base 101 and the H-shaped support frame 102, ensuring the stability of their connection.

[0035] The quick-change assembly also includes a trapezoidal toolbox 108, with the trapezoidal toolbox 108 being fixedly connected between the H-type support frame 102 and the limiting rod 103.

[0036] The trapezoidal toolbox 108 contains tools for replacing the filter cloth on the filter fan.

[0037] The quick-change component also includes a rectangular block 109, a square block 1010 and a circular hole 1011. The rectangular block 109 and the square block 1010 are fixedly connected to the base 101. A circular hole 1011 is opened in the middle of the square block 1010.

[0038] There are two rectangular blocks 109 in total, and the gap between them is used to snap the wide flat area of ​​the filter fan. The circular hole 1011 in the middle of the square block 1010 is used to snap the narrow cylindrical area of ​​the filter fan. The above steps realize the fixation of the filter fan, thereby facilitating the installation or removal of the filter cloth from one end.

[0039] Working principle: After removing the filter fan, insert the flat end of the filter fan with the old filter cloth into the gap between the two rectangular blocks 109. Then, take out the tool from the trapezoidal toolbox 108 to remove the clamp on the cylindrical end of the filter fan, and then remove the old filter cloth. Then, insert the flat end of the filter fan with the removed filter cloth into the gap between the two rectangular blocks 109. Put the new filter cloth on the filter fan. At this time, remove the filter fan along with the filter cloth. Insert the cylindrical end of the filter fan into the circular hole 1011. Then move the filter cloth so that it completely surrounds the flat end of the filter fan. Then, clamp the filter fan along with the new filter cloth into the gap between the two rectangular blocks 109. Use the tool in the trapezoidal toolbox 108 to completely fit the other parts of the new filter cloth onto the cylindrical end of the filter fan. Then, use the clamp to firmly clamp it. Then, place the filter fan with the replaced filter cloth between the corresponding adjacent limit rods 103, and insert its bottom into the circular tube 104.

[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The guide and quick-locking assembly includes a rectangular block 201, a slot 202, and a magnetic block 203. The rectangular block 201 is fixedly installed on the middle position limiting rod 103. The total number of guide cylinders 105 is one less than that of the limiting rods 103. The guide cylinders 105 are fixedly installed on all the other limiting rods 103 except the middle position. The slot 202 is opened through the middle of the rectangular block 201. The magnetic block 203 is fixedly installed in the middle of the slot 202. The magnetic block 203 is magnetically connected to the pull rod 106.

[0042] The quantity and installation position of the guide cylinders 105 can limit and guide the movement of the pull rod 106, preventing the pull rod 106 from tilting up and down, and enabling the pull rod 106 to move quickly, thereby indirectly improving the installation and disassembly efficiency of the filter fan. The rectangular block 201 provides a guarantee for the opening of the slot 202. The slot 202 can effectively limit the insertion ends of the two pull rods 106, and the installation of the magnetic block 203 in the middle of the slot 202 can further securely connect the pull rods 106, preventing them from shaking and slipping during connection.

[0043] Working principle: Before removing the filter fan with the waste filter cloth attached, pull the pull rod 106 first. At this time, the pull rod 106 moves along the guide cylinder 105. After the filter fan with the waste filter cloth attached is removed, the operator moves the pull rod 106 in the opposite direction until the insertion end of the pull rod 106 is inserted into the slot 202. At this time, the magnetic block 203 magnetically connects it. When installing the filter fan with the new filter cloth attached, the above process is repeated in reverse.
