[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a method for using a microporous filtration device in a three-in-one filtration device.

[0041] Embodiment 1:

[0042] See also Figure 1 - Fig. 9 A microporous filtration device comprises a filtration chamber 1, a stirring mechanism 2 and a bottom filtration mechanism 4, wherein the stirring mechanism 2 is installed at the top of the filtration chamber 1, the bottom filtration mechanism 4 is arranged below the filtration chamber 1, an internal filtration mechanism 3 is installed inside the filtration chamber 1, a feed inlet 5 is installed at the top of the filtration chamber 1, a pressure valve port 6 is installed at the top of the filtration chamber 1, a discharge port 7 is installed outside the filtration chamber 1, and a heating mechanism 8 is fixedly installed inside the side wall of the filtration chamber 1;

[0043] The stirring mechanism 2 includes a hydraulic telescopic rod 22 and a motor transmission rod 28. The hydraulic telescopic rod 22 can drive the motor transmission rod 28 to move up and down. The bottom of the motor transmission rod 28 passes through the top of the filter chamber 1 and extends into the interior of the filter chamber 1.

[0044] The internal filtering mechanism 3 includes a filtering connection ring 33 and a filtering sleeve 34, and a plurality of filtering sleeves 34 are movably mounted at the bottom of the filtering connection ring 33;

[0045] The bottom filtering mechanism 4 can seal the bottom of the filtering chamber 1, the stirring mechanism 2 can stir the suspension inside the filtering chamber 1, the air pressure valve port 6 can pressurize the inside of the filtering chamber 1, the filtering sleeve 34 and the bottom filtering mechanism 4 can filter the washing liquid in the suspension, discharge the washing liquid to form a filter cake with the particles in the suspension, and then inject the washing liquid into the filtering chamber 1 through the feed port 5, repeatedly stir and filter to purify the filter cake, and the heating mechanism 8 and the stirring mechanism 2 can dry and crush the filter cake.

[0046] During operation, the bottom of the filter bin 1 is first sealed through the bottom filter mechanism 4, and then the suspension is injected into the filter bin 1 through the feed port 5. After the suspension is injected, the inside of the filter bin 1 is pressurized through the air pressure valve port 6. After the pressure inside the filter bin 1 rises, the washing liquid in the suspension can be discharged from the filter bin 1 under the filtration of the bottom filter mechanism 4 and the filter sleeve 34. During the filtration process, the stirring mechanism 2 can stir the suspension to prevent the particles in the suspension from settling quickly. When the motor drive rod 28 moves up and down to make the stirring more uniform, it can also drive the filter sleeve 34 to move up and down synchronously, so that the filter sleeve 34 is always in contact with the suspension. After the washing liquid in the suspension is completely discharged, the particles in the suspension form a filter cake. Then, washing liquid is injected into the filter bin 1 through the feed port 5, and the filter cake is broken up by the stirring mechanism 2 to form a suspension for washing and filtration. The above washing work is repeated until the filter cake meets the requirements, and then the inside of the filter bin 1 is heated by the heating mechanism 8, and stirred by the stirring mechanism 2 to dry and crush the filter cake, and then the filter cake in the filter bin 1 is discharged through the discharge port 7, and the residual filter cake remains on the bottom filter mechanism 4. In the process of filtering the suspension, by increasing the pressure inside the filter bin 1 and arranging a plurality of filter sleeves 34 inside the filter bin 1, the filter sleeve 34 and the bottom filter mechanism 4 are used to filter the suspension together, which can significantly increase the filtration area and filtration efficiency, thereby improving the filtration effect.

[0047] Embodiment 2:

[0048] See also Figure 3 - Figure 6, the difference from the above embodiment is that the stirring mechanism 2 includes a mounting base 21, the mounting base 21 is fixedly mounted on the top of the filter bin 1, a hydraulic telescopic rod 22 is fixedly mounted on the top of the mounting base 21, a lifting sliding column 23 is fixedly mounted on the top of the mounting base 21, the movable end of the hydraulic telescopic rod 22 is connected to a lifting platform 24, a driving motor 25 is fixedly mounted on the top of the lifting platform 24, a motor gear 26 is mounted on the output end of the driving motor 25, the internal rotation of the lifting platform 24 is mounted on a motor transmission rod 28, a transmission gear 27 is mounted on the top of the motor transmission rod 28, a stirring blade 29 is mounted on the bottom of the motor transmission rod 28, and a lifting block 210 is fixedly mounted on the outside of the motor transmission rod 28.

[0049] The lifting platform 24 is movably mounted on the top of the mounting base 21 through a hydraulic telescopic rod 22, and the interior of the lifting platform 24 is slidably connected to the exterior of the lifting sliding column 23;

[0050] The hydraulic telescopic rod 22 can drive the lifting platform 24 to move up and down on the top of the mounting base 21. The lifting platform 24 can move up and down along the outside of the lifting sliding column 23. When the lifting platform 24 moves up and down, it can drive the drive motor 25 and the motor transmission rod 28 to move up and down. When the motor transmission rod 28 moves up and down, it can drive the stirring blade 29 and the lifting block 210 to move up and down inside the filter bin 1.

[0051] The top of the motor transmission rod 28 is connected to the driving motor 25 through the transmission gear 27 and the motor gear 26, and the outside of the motor transmission rod 28 is in contact with the internal filtering mechanism 3 through the lifting block 210;

[0052] When the driving motor 25 is started, it can drive the motor transmission rod 28 to rotate. When the motor transmission rod 28 rotates, it can drive the stirring blade 29 to stir the suspension inside the filter chamber 1.

[0053] During operation, the extension and contraction of the hydraulic telescopic rod 22 can drive the lifting platform 24 to move up and down along the lifting sliding column 23. When the lifting platform 24 moves up and down, it can synchronously drive the motor transmission rod 28 to move up and down. When the motor transmission rod 28 moves up and down, it can drive the stirring blade 29 to move up and down inside the filter bin 1. The up and down movement of the stirring blade 29 can stir the suspension and filter cake at different liquid level heights. When the motor transmission rod 28 moves up and down, the height of the filter sleeve 34 can be adjusted by the lifting block 210, so that the bottom of the filter sleeve 34 is always in contact with the suspension. When the stirring blade 29 stirs the suspension, it can prevent the particles in the suspension from settling, and make the washing liquid clean the particles more evenly. The adjustment of the height of the filter sleeve 34 can make the filter sleeve always located inside the suspension, so as to prevent the air inside the filter bin 1 from being discharged from the internal filtering mechanism 3 during the filtering process, resulting in a decrease in the internal pressure of the filter bin 1.

[0054] Embodiment three:

[0055] See also Figure 5 - Figure 8 , which is different from the above-mentioned embodiment, the internal filtering mechanism 3 comprises a fixed connecting pipe 31, which is fixedly mounted on the inner wall of the filtering bin 1, one end of which is connected to a lower connecting pipe 32, and the other end of which is fixedly connected to a filtering connecting ring 33, and the outsides of the plurality of filtering sleeves 34 are all fixedly connected to filtering connecting rods 35, and the other ends of the plurality of filtering connecting rods 35 are all fixedly connected to the same connecting rod transmission ring 36;

[0056] The interior of the connecting rod transmission ring 36 does not contact the motor transmission rod 28 , and the bottom of the connecting rod transmission ring 36 contacts the top of the lifting block 210 .

[0057] The filter sleeve 34 includes a connecting sleeve 341, which is fixedly mounted on the bottom of the filter connecting ring 33, a sleeve limiting block 342 is fixedly connected to the bottom of the connecting sleeve 341, an external filter sleeve 343 is slidably mounted on the outside of the connecting sleeve 341, an internal connecting sleeve 345 is slidably mounted on the inside of the connecting sleeve 341, and the outside of the external filter sleeve 343 is fixedly connected to the filter connecting rod 35;

[0058] The bottom of the internal connecting sleeve 345 is fixedly connected to the bottom of the outside filter sleeve 343 through the sleeve connecting block 344. There is a gap at the connection between the internal connecting sleeve 345 and the sleeve connecting block 344. The outside of the connecting sleeve 341 fits with the external filter sleeve 343. The inside of the connecting sleeve 341 fits with the internal connecting sleeve 345.

[0061] During operation, after the internal pressure of the filter chamber 1 increases, the washing liquid in the suspension can move upward along the filter sleeve 34, and then be discharged from the inside of the filter chamber 1 through the filter connecting ring 33 and the fixed connecting pipe 31. During filtering, the external filter sleeve 343 can isolate the particles in the suspension outside the external filter sleeve 343, and the washing liquid in the suspension can pass through the external filter sleeve 343, and then enter the filter connecting ring 33 through the internal connecting sleeve 345 and the connecting sleeve 341. When the motor drive rod 28 moves upward, the connecting rod drive ring 36 can be driven to move upward through the lifting block 210, and when the connecting rod drive ring 36 moves upward, the external filter sleeve can be driven through the filter connecting rod 35. 343 and the internal connecting sleeve 345 move upward, and when the motor transmission rod 28 moves downward, it can drive the lifting block 210 to move downward. When the lifting block 210 moves downward, the external filter sleeve 343 and the internal connecting sleeve 345 can move downward under the action of gravity, so that when the external filter sleeve 343 and the internal connecting sleeve 345 move downward, they can drive the connecting rod transmission ring 36 to move downward. By setting a plurality of filter sleeves 34, the filtering area and filtering effect can be increased. As the stirring blade 29 moves up and down, the external filter sleeve 343 can always be in the suspension, which can prevent the gas inside the filter chamber 1 from being discharged from the internal filter mechanism 3, resulting in a decrease in the internal pressure of the filter chamber 1.

[0065] The sealed bottom cover 41 can seal the bottom of the filter chamber 1 , the bottom filter screen 42 can filter the washing liquid in the suspension, and the drainage pipe 45 can discharge the filtered washing liquid.

[0066] During operation, the sealing bottom cover 41 can seal the bottom of the filter bin 1, and the mounting buckle 43 can fix the sealing bottom cover 41 to the bottom of the filter bin 1; during washing and filtering, the bottom filter screen 42 can separate and filter the particles in the suspension and the washing liquid, leaving the particles in the suspension inside the filter bin 1, while the washing liquid in the suspension can pass through the bottom filter screen 42 and then be discharged from the drainage pipe 45; after washing and drying, the remaining filter cake can remain on the surface of the bottom filter screen 42; the detachable structure of the sealing bottom cover 41 makes it easier to clean and maintain the interior of the filter bin 1.
