[0035] Example 1

[0036] This embodiment applies to a filtration device used for filtering air.

[0037] Please see Figures 1 to 3 This embodiment provides an air filter fixing bracket 100, which includes a body 110, a pressure block 120, a limiting member 130, and an elastic member 140.

[0038] The main body 110 is provided with a connecting part 111, a rod part 112 and a plug-in part 113. The connecting part 111 is located at one end of the rod part 112, and the plug-in part 113 is provided on the outer wall of the rod part 112, and the plug-in direction is parallel to the axial direction of the rod part 112.

[0039] The connecting part 111 includes a first surface and a second surface, the first surface and the second surface are disposed opposite to each other, and the first surface faces the insertion part 113. One end of the insertion part 113 extends to the first surface, and the second surface is provided with a positioning part 114.

[0040] In this embodiment, the connecting part 111 can be set to be cylindrical, with a first surface being circular and a second surface being circular, and the axis of the rod part 112 being located at the center of the connecting part 111.

[0041] During manufacturing, the connecting part 111 is welded to the rod part 112 to form a welded rod. The end of the rod part 112 away from the connecting part 111 is provided with an external thread. It can be understood that the rod part 112 can be configured as a screw, and the screw is welded to the connecting part 111 to form a welded screw.

[0042] The pressure block 120 is fitted onto the body 110. Specifically, the pressure block 120 is fitted onto the rod 112. The pressure block 120 has a slot 1211, which engages with the insertion part 113.

[0043] In this embodiment, the pressure block 120 is provided with a sleeve 121 and a pressing part 122. The sleeve 121 is sleeved on the body 110, the elastic member 140 is supported on the end of the sleeve 121, and the sleeve 121 is provided with a slot 1211. The slot 1211 is provided on the inner wall of the sleeve 121, and the pressing part 122 is provided on the outer wall of the sleeve 121.

[0044] The pressure block 120 is also provided with reinforcing ribs 123, which are connected to the sleeve 121 and the pressing part 122 respectively. The reinforcing ribs 123 can improve the strength of the pressure block 120 and prevent the pressing part 122 from bending and deforming.

[0045] There are two pressing parts 122, which are symmetrically arranged along the radial direction of the sleeve 121. The number of reinforcing ribs 123 is the same as that of the pressing parts 122 and they correspond one-to-one.

[0046] The limiting member 130 is installed on the body 110. Specifically, the limiting member 130 is installed on the other end of the rod 112. The limiting member 130 is detachably connected to the body 110. In this embodiment, the limiting member 130 is provided with an internal thread, that is, the limiting member 130 is threadedly connected to the rod 112, thereby realizing the detachable connection between the limiting member 130 and the body 110.

[0047] During manufacturing, the limiting member 130 can be configured as a nut.

[0048] The elastic element 140 is supported between the limiting member 130 and the pressure block 120 along the insertion direction of the insertion portion 113. In this embodiment, the elastic element 140 is sleeved on the rod portion 112. In this embodiment, the elastic element 140 can be configured as a compression spring.

[0049] When the plug part 113 disengages from the slot 1211, the elastic element 140 deforms; when the plug part 113 is inside the slot 1211, the elastic element 140 returns to its original shape.

[0050] Based on the above, this embodiment further explains the installation principle of the air filter fixing bracket 100 as follows:

[0052] S200. First, fit the pressure block 120 into the rod 112, and then fit the elastic element 140 into the rod 112.

[0053] S300. Screw the limiter 130 onto the other end of the rod 112.

[0054] Example 2

[0055] Please see Figures 4 to 6 Based on the above embodiments, this embodiment provides a filtration device, which includes an air filter element 200, a perforated plate 300, and an air filter element fixing bracket 100 of Embodiment 1. The air filter element fixing bracket 100 is fixed to the air filter element 200 and the perforated plate 300.

[0056] The air filter element 200 is provided with a flange cover 210 on top.

[0057] Please see Figure 5 The tube sheet 300 is provided with a positioning groove 310, which cooperates with the positioning part 114 of the air filter fixing bracket 100 to achieve the positioning function.

[0058] In practical applications, after the positioning part 114 and the positioning groove 310 are engaged, welding is performed at the connection between the air filter element fixing bracket 100 and the tube sheet 300, thereby improving the stability and reliability of the air filter element fixing bracket 100 and preventing gas leakage when filtering high-pressure gas.

[0059] Please see Figure 2 , Figure 7 and Figure 8 Based on the above, this embodiment further explains the operating principle of the filtration device as follows:

[0060] S110. Lift the pressure block 120 upwards, so that the slot 1211 disengages from the insertion part 113, the holding part 122 leaves the flange cover 210, the fixation is released, and the elastic element 140 is compressed and stored.

[0061] S120. Rotate the pressure block 120 to keep the slot 1211 from the insertion part 113.

[0062] S130. Replace the filter element.

[0063] S140. Rotate the pressure block 120 again so that the slot 1211 engages with the insertion part 113 and the pressing part 122 presses against the flange cover 210 to achieve fixation.

[0064] In this embodiment, two air filter elements 200 can be arranged along the first direction. After rotating 90°, the pressing part 122 leaves the flange cover 210. After rotating 90° in the opposite direction, the pressing part 122 presses back onto the flange cover 210.

[0065] In this embodiment, the insertion part 113 cooperates with the slot 1211 to press the pressure block 120 against the air filter element 200, thereby fixing the air filter element 200. Then, by disengaging the insertion part 113 from the slot 1211, the air filter element 200 can be replaced. In addition, this embodiment is provided with an elastic element 140, which can automatically reset when fixing and replacing the air filter element 200, simplifying the disassembly and assembly process of replacing the air filter element 200, making it easy to operate and saving time and effort.
