[0002] Microporous filter is a new type of filtration equipment that uses tiny particles in the filter material to form a screening device or filter element in the fluid medium. It has the advantages of small size, light weight, compact structure, high filtration accuracy, fast transition speed, less adsorption, no medium shedding, acid and alkali corrosion resistance, and easy operation. Microporous filter can filter out particles and bacteria above 0.1um in liquid or gas, and is now widely used as necessary equipment in industries such as medicine, chemical industry, electronics, beverages, fruit wine, biochemical water treatment, and environmental protection.

[0003] After searching, application number 202120764727.2 discloses a microporous filter, including a base, a sealing cover is arranged on the base, a filter element located in the sealing cover is clamped on the base, and a connecting assembly is arranged on the base. The connecting assembly includes two clamping rings, two connecting half rings and a locking piece. The two clamping rings are respectively installed on the base and the sealing cover, and the connecting half rings are clamped and installed on the two clamping rings. One end of the two connecting half rings is rotatably connected, and the locking piece is installed at the other end of the two connecting half rings and is used to connect the two connecting half rings. The two clamping rings are pressed against each other under the action of the connecting half rings. The present application has the effect of reducing the time required for the removal and installation of the filter element, thereby increasing the production efficiency of the microporous filter.

[0026] As mentioned above, in this case, when in use, the water bucket 301 is connected to the bottom of the inner cavity of the filter body 1, and after the three filter elements 3 are placed on the water bucket 301, the card plate 4 is placed on the internal ring plate of the filter body 1, and the card plate 4 is clamped on the top of the three filter elements 3, and the top cover 2 is placed as a whole. After all the components are placed, the threaded tube 201 is rotated to drive the driving disk 202 to rotate, and the inner extrusion block 2021 and the outer extrusion block 2022 on the driving disk 202 respectively squeeze the card blocks 401 on both sides of the three filter elements 3. The card block 401 is squeezed in the top slide of the card plate 4 and slides until the head of the card block 401 is clamped in the annular groove of the installation head 302, that is, the fixation is completed. When it needs to be dismantled for maintenance, it only needs to be rotated in the opposite direction, so that after the card block 401 leaves, the top cover 2 can be removed to maintain the interior. The device is simple and efficient to operate, and has strong linkage and good fixing effect.

[0027] like Figure 1-Figure 5 As shown, the top of the threaded tube 201 is fixedly connected to a hand wheel 2011 , the hand wheel 2011 is designed to be anti-slip, and a spring 402 is connected between the side of the clamping block 401 away from the mounting head 302 and the corresponding groove on the top of the clamping plate 4 .

[0028] As mentioned above, a hand wheel 2011 is set at the top of the threaded tube 201, which is convenient for driving the threaded tube 201 to drive the driving disk 202 at the bottom to rotate stably during work, and a spring 402 is connected to the tail of the block 401, so that the tension generated by the spring 402 during disassembly drives the block 401 to automatically leave, thereby improving the disassembly efficiency.

[0029] like Figure 1-Figure 3As shown, a water inlet 101 is provided on the upper side of the filter body 1, a water outlet 102 is provided at the bottom of the filter body 1, the water outlet 102 is connected to the bottom of the water outlet bucket 301, a water outlet pipe 1022 is provided on the side wall of the water outlet 102, a control plug 1021 is threadedly connected below the water outlet 102, a sewage outlet 103 is provided below the filter body 1 on the opposite side of the water inlet 101, a valve 1031 is provided on the sewage outlet 103, the filter body 1 is placed on the base 5, four universal wheels 501 are provided at the bottom of the base 5, brake pads are installed on the universal wheels 501, and the top cover 2 is mounted on the top of the filter body 1 using a bump snap-fit.

The material enters the filter body 1 through the water inlet 101, and the material filtered by the filter element 3 flows out from the bottom water outlet pipe 1022, and the impurities generated by the filtration can flow out from the sewage outlet 103. The filter body 1 is placed on the top of the base 5, and the base 5 is provided with a universal wheel 501 with a brake pad, which can reduce the wear on the filter body 1 and facilitate the movement and fixation of the device. The top cover 2 and the filter body 1 are installed by snap-fitting, which is simple to operate, stable to install, and easy to disassemble and maintain.

[0031] like Figure 5-Figure 7 As shown, the clamping surface of the clamping block 401 is designed to be an arc-shaped surface, and the inner extrusion block 2021 and the outer extrusion block 2022 are evenly distributed along the center of the driving disk 202, corresponding to three filter elements 3 respectively.

[0032] As mentioned above, the clamping surface of the clamping block 401 is designed to be an arc-shaped surface, which is more conducive to fitting with the annular groove of the mounting head 302 during the clamping and fixing process, thereby enhancing the fixing effect.

[0033] Working principle: When using this case, after placing all the components, turn the handwheel 2011 to drive the bottom threaded tube 201 to rotate, and the threaded tube 201 drives the driving disk 202 to rotate. The inner extrusion block 2021 and the outer extrusion block 2022 on the driving disk 202 respectively squeeze the blocks 401 on both sides of the filter element 3 at three places, and the blocks 401 are squeezed in the top slide of the card plate 4 to slide until the arc-shaped part of the head of the block 401 is stuck in the annular groove of the mounting head 302, which means that the fixation is completed and it cannot be rotated. When it needs to be dismantled for maintenance, it only needs to be rotated in the opposite direction. After the tension generated by the spring 402 drives the block 401 to automatically leave, the top cover 2 can be removed and the internal maintenance can be carried out. The operation of this device is simple and efficient, and the linkage is strong and the fixing effect is good.
