[0028] Please refer again Figures 1 to 9 The fixing mechanism 200 is used to fix the protection mechanism 100 to the filter plate groove 44 and includes a slider 20, a track 25a, a telescopic spring 27, and a connecting band 26. The slider 20 and the track 25a are respectively mounted on the first clamping plate 10, and the telescopic spring 27 and the connecting band 26 are respectively mounted on the second clamping plate 11. Furthermore, the telescopic spring 27 is mounted in the telescopic spring groove 15 of the second clamping plate 11. One side of the telescopic spring 27 is fixed to one side of the telescopic spring groove 15 by conventional means, such as welding, but not limited thereto. The connecting band 26 has a through hole 26b and a connecting hole 26a at both ends. The other side of the telescopic spring 27 passes through the connecting hole 26a and is fixed to one end of the connecting band 26.

[0029] The slider 20 includes a slider upper plate 21 , a slider lower plate 22 , a spring sheet 23 , and a spring 24 .

The slider 20 slides in the track 25a, tightening the connecting belt 26, thereby fixing the first splint 10 and the second splint 11 together.

[0030] It can be understood that the spring groove 22d is used to install the spring 24, which is used to prevent the spring 24 from deflecting during movement. The spring piece 23 is composed of two fixed ends 23a and a positioning end 23b. The fixed end 23a can engage the serrated protrusion to fix the slider 20.

[0034] Please refer again Figures 1 to 9 It can be understood that the filter cloth 42 is fixed to the filter plate groove 44 via a rubber ring 45. In order to reinforce and fix the filter plate 43, filter cloth 42 and rubber ring 45 that are tightly connected, a reinforcement and leak-proof device is invented to reduce the material loss of the leaf filter. The fixing strip 12 reinforces and seals the filter plate 43, filter cloth 42 and rubber ring 45. The fixing strip 12 is reinforced by a fixing mechanism 200 connected to the first plywood 10 and the second plywood 11 of the protection mechanism 100, and is reinforced at the filter plate groove 44. In the fixing mechanism 200, one side of the connecting belt 26 is connected to the slider 20, and the other side is connected to the telescopic spring 27. The telescopic spring 27 can adjust the length of the connecting belt 26. Press the slider 20, and the slider 20 slides in the track 25a. After releasing the hand, the spring 24 bounces the slider 20 up, and the clamping end 23a of the spring sheet 23 fixes the serrated protrusion on the track plate 25, and then adjusts the length between the first splint 10 and the second splint 11 according to the thickness of the filter plate 43, the filter cloth 42 and the rubber ring 45, and the reinforced anti-leakage device is tightly fixed in the filter plate groove 44.

[0035] Working principle of the present invention: Before the leaf filter starts working, several filter plates 43 and filter cloths 42 should be installed as needed. The filter cloth 42 is fixed to the edge of the filter plate 43 with a rubber ring 45, and several of the reinforcement and leak-proof devices are respectively installed on both sides of the filter plate 43. The positioning protrusion 12a of the fixing strip 12 in the protective mechanism 200 is used to position the fixing block 12b and fix it on one side of the edge of the filter plate 43. The fixing block 12b is inserted into the filter plate groove 44, pressed and ensured that the fixing strip 12 is pressed against the rubber ring 45 and the filter cloth 42 is tightly connected to the filter plate 43. Track plate grooves 13 are respectively provided on the first splint 10 near the two ends away from the filter plate 43. The track plate 25 is installed in the track plate groove 13. A track 25a is provided in the track plate 25. The slider 20 slides in the track 25a. The telescopic spring 27 is installed and fixed to the second splint 1 1 In the telescopic spring groove 15, the slider 20 is connected to one side of the connecting belt 26, and the other side of the connecting belt 26 is connected to the telescopic spring 27, which stretches and contracts, pressing and pushing the sliders 20 on both sides of the first clamping plate 10 to move toward each other in the track 25a, thereby adjusting and tightening the length of the connecting belt 26. Stop pressing the slider 20, and the spring piece 23 of the slider 20 The clamping end 23a fixes the serrated protrusion on the track plate 25, thereby tightening and fixing the first clamping plate 10 and the second clamping plate 11, completing the fixation of the upper part of the filter plate 43. If the lower part of the filter plate 43 needs to be installed, the reinforcement and leak-proof device is rotated 180°, and the reinforcement of the lower part is completed according to the above steps. After the completed filter plate 43 and the filter cloth 42 are reinforced, they are installed on the leaf filter using the ear holes 41 and the filter plate positioning holes. The filter plate positioning holes are consistent with the positioning holes 16. If replacement is required, press the slider 20 in the opposite direction, loosen the first clamping plate 10 and the second clamping plate 11, pull the clamping strip 12 out of the filter plate groove 44, and remove the reinforcement and leak-proof device. From the above process, it can be seen that the clamping strip 12 is used to further fix and seal the filter plate 43, the filter cloth 42 and the rubber ring 45. The track plate 25 and the serrated protrusions provided on the track plate 25 are made of sheet metal and are firmly fixed. The slider 20, the connecting belt 26 and the telescopic spring 27 of the fixing mechanism 200 cooperate with each other. The tightness of the fixing mechanism 200 is adjusted according to the thickness of the filter plate 43 and the filter cloth 42, thereby fixing the first clamping plate 10 and the second clamping plate 11. The assembly and disassembly efficiency is high, and the flexibility of the two clamping plates is high. It is not easy to damage the filter plate 43, and the number of effective uses of the filter cloth 42 fixing the filter plate 43 without leakage is increased, the service life is extended, and the maintenance cost is moderate.

[0036] The present invention also provides a reinforcement and leakage prevention method for reducing material loss in a leaf filter, wherein the reinforcement and leakage prevention method adopts the above reinforcement and leakage prevention device and comprises the following steps: S1: Place the filter cloth 42 on the filter plate 43, use the rubber ring 45 to fix the two sides of the filter cloth 42 to the filter plate groove 44, install the reinforcement and leak-proof device on the opposite sides of the filter plate 43, use the positioning protrusion 12a to locate the fixing block 12b, and insert the fixing block 12b into the filter plate groove 44, press and ensure that the fixing strip 12 is pressed against the rubber ring 45 and the filter cloth 42 is tightly connected to the filter plate 43; Furthermore, the positioning protrusion 12a of the fixing strip 12 is used to position the reinforcement leak-proof device on one side of the filter plate inlet groove 44, and the fixing block 12b of the fixing strip 12 is fixed to the filter plate groove 44. The fixing strip 12 is pressed to increase the contact area between the fixing block 12b, the rubber ring 45 and the filter cloth 42 on the filter plate 43, and ensure a tight connection. S2: The two fixing mechanisms 200 are respectively installed at both ends of the first clamping plate 10 and the second clamping plate 11, connecting the first clamping plate 10 and the second clamping plate 11. By controlling the mutual cooperation of the fixing mechanisms 200: the two sliders 20 of the first clamping plate 10 are pressed to move relative to each other, driving and tightening the connecting belt 26 and the telescopic spring 27 located on the second clamping plate 11, and then releasing the slider 20.
