Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical reagent filtration technology, and in particular to a self-cleaning microporous membrane chemical reagent filtration device. Background Technology
[0002] Microporous membranes are porous films made of polymers and are used to filter crystalline precipitates from chemical reagents. Some chemical reagents produce crystals or precipitates during production; to remove these precipitates, microporous membranes are typically used to filter the reagents, resulting in a purer product.
[0003] Currently, when filtering chemical reagents using microporous membranes, the resulting crystals and precipitates remain on the surface of the membrane. Over time, this can easily cause clogging of the membrane, thus affecting the filtration of chemical reagents. However, microporous membranes can be reused multiple times when cleaned under specified operating conditions. Therefore, a self-cleaning microporous membrane chemical reagent filtration device is needed to meet the application requirements. Utility Model Content

[0012] The beneficial effects of this utility model are:
[0013] In this invention, the extension of the electric adjusting rod will move the second support block, the guide tube, and the nozzle forward, positioning the nozzle at the opening of the filter tank. Then, the pump body will be activated, and the pump body will pump the cleaning solution into the delivery tube through the pumping pipe. The cleaning solution will enter the hose through the delivery tube, and then enter the guide tube through the hose. Finally, it will be sprayed onto the microporous filter membrane through the nozzle, continuously rinsing and cleaning the microporous filter membrane to ensure its normal use without clogging.
[0014] In this invention, the extension of the miniature electric push rod causes the L-shaped fixing block to slide forward inside the filter tank and press against the microporous filter membrane to fix it. The sealing sleeve can seal the contact surface between the L-shaped fixing block and the filter tank. Then, the drive motor is started, and the rotation of the drive motor will drive the half gear to rotate. One rotation of the half gear will drive the rotating shaft to rotate half a rotation.

[0021] Example:
[0022] like Figure 1-5 As shown, this embodiment provides a self-cleaning microporous membrane chemical reagent filtration device, including a base 1, a vertical plate 2 mounted on the base 1, a rotating shaft 3 rotatably mounted inside the vertical plate 2, a filter tank 4 mounted at the end of the rotating shaft 3, a strainer 5 installed inside the filter tank 4, a microporous membrane 6 disposed inside the filter tank 4, a fixing mechanism 7 disposed on the filter tank 4, a rotating drive mechanism 8 disposed on the vertical plate 2 and the rotating shaft 3, and a cleaning mechanism 9 disposed on the base 1 and the vertical plate 2; the microporous membrane 6 is placed on the strainer 5, and the chemical reagent to be filtered is poured into the filter tank 4. The chemical reagent poured into the filter tank 4 will be filtered by the microporous membrane 6 and flow out from the bottom of the filter tank 4 through the strainer 5. A collection container can be placed below the filter tank 4 to collect the filtered chemical reagent. When the microporous filter membrane 6 needs to be cleaned, the fixing mechanism 7 can fix the microporous filter membrane 6, and the flipping drive mechanism 8 will drive the flipping shaft 3 to rotate 180 degrees, thereby flipping the opening of the filter tank 4 to the bottom. The cleaning mechanism 9 sprays cleaning liquid onto the microporous filter membrane 6, continuously rinsing and cleaning the microporous filter membrane 6 to ensure that the microporous filter membrane 6 is not clogged during normal use, and the waste liquid after rinsing is collected.
[0023] To secure the microporous filter membrane 6 before cleaning, a fixing mechanism 7 includes an L-shaped fixing block 71 slidably installed inside the filter canister 4. A sealing sleeve 72 is fixedly fitted onto the L-shaped fixing block 71. A first support block 73 is installed on the filter canister 4, and a miniature electric push rod 74 is installed on the first support block 73. The L-shaped fixing block 71 is installed at the output end of the miniature electric push rod 74. When cleaning of the microporous filter membrane 6 is required, the miniature electric push rod 74 extends, causing the L-shaped fixing block 71 to slide forward inside the filter canister 4 and press against the microporous filter membrane 6 to secure it. The sealing sleeve 72 seals the contact surface between the L-shaped fixing block 71 and the filter canister 4.
[0024] To clean the filter canister 4, it is flipped over. The flipping drive mechanism 8 includes a rotating shaft 81 mounted on the other end of the flipping shaft 3, a half gear 82 meshing on the rotating shaft 81, a support plate 83 mounted on the vertical plate 2, and a drive motor 84 mounted on the support plate 83. The half gear 82 is mounted on the output end of the drive motor 84. When the drive motor 84 rotates, it drives the half gear 82 to rotate. One rotation of the half gear 82 drives the rotating shaft 81 to rotate half a rotation. The rotation of the rotating shaft 81 half a rotation drives the flipping shaft 3 to rotate 180 degrees, thereby flipping the opening of the filter canister 4 to the bottom.
[0025] To clean the microporous filter membrane 6, a cleaning mechanism 9 is installed on a base 1. A pump body 92 is installed inside the cleaning liquid tank 91. The pump body 92 has a pumping pipe 93 and a delivery pipe 94 installed at its inlet and outlet. A hose 95 is installed on the delivery pipe 94, a conduit 96 is installed on the hose 95, and a nozzle 97 is installed on the conduit 96. A collection cylinder 98 is installed on the base 1. The pump body 92 pumps the cleaning liquid into the delivery pipe 94 through the pumping pipe 93. The cleaning liquid then enters the hose 95 through the delivery pipe 94, and then enters the conduit 96 through the hose 95. Finally, it is sprayed onto the microporous filter membrane 6 through the nozzle 97, continuously cleaning the microporous filter membrane 6 and ensuring its normal use without clogging. The collection cylinder 98 is placed on the base 1 beforehand to collect the waste liquid after rinsing.
[0026] To adjust the position of nozzle 97, brackets 99 and second support blocks 911 are respectively installed on vertical plate 2 and guide tube 96. Electric adjusting rods 910 are installed on brackets 99 and second support blocks 911. When the electric adjusting rod 910 extends, it will move the second support block 911, guide tube 96, and nozzle 97 forward, positioning nozzle 97 at the opening of filter tank 4. When the electric adjusting rod 910 retracts, it will move nozzle 97 backward, misaligning it with filter tank 4, without affecting the collection of filtered chemical reagents.
[0027] To facilitate the addition of cleaning fluid to the cleaning fluid tank 91, a level bar 912 and a filling pipe 913 are provided on the cleaning fluid tank 91; the cleaning fluid in the cleaning fluid tank 91 can be observed through the level bar 912, and the cleaning fluid can be added to the cleaning fluid tank 91 through the filling pipe 913.
[0028] Working principle: In use, place the microporous filter membrane 6 on the strainer 5 and pour the chemical reagent to be filtered into the filter canister 4. The chemical reagent poured into the filter canister 4 will be filtered by the microporous filter membrane 6 and flow out from the bottom of the filter canister 4 through the strainer 5. A collection container can be placed below the filter canister 4 to collect the filtered chemical reagent. When it is necessary to clean the microporous filter membrane 6, the miniature electric push rod 74 extends and drives the L-shaped fixing block 71 to slide forward in the filter canister 4 and press against the microporous filter membrane 6 to fix the microporous filter membrane 6. The sealing sleeve 72 can seal the contact surface between the L-shaped fixing block 71 and the filter canister 4. Then, start the drive motor 84. The rotation of the drive motor 84 will drive the half gear 82 to rotate. One rotation of the half gear 82 will drive the rotating shaft 81 to rotate half a rotation. The rotation of the rotating shaft 81 will drive the flipping shaft 3 to rotate 180 degrees, thereby flipping the opening of the filter canister 4 to the bottom. At this time, start the electric adjusting rod 910 to adjust the electric adjustment. When the extension of the lever 910 is activated, it will move the second support block 911, the conduit 96, and the nozzle 97 forward, positioning the nozzle 97 at the opening of the filter tank 4. Then, the pump body 92 will be activated, and the pump body 92 will pump the cleaning liquid into the delivery pipe 94 through the pumping pipe 93. The cleaning liquid will enter the hose 95 through the delivery pipe 94, and then enter the conduit 96 through the hose 95. Finally, it will be sprayed onto the microporous filter membrane 6 through the nozzle 97, continuously rinsing and cleaning the microporous filter membrane 6 to ensure that the microporous filter membrane 6 can be used normally without clogging. A collection cylinder 98 is placed on the base 1 in advance to collect the waste liquid after rinsing during the rinsing process.
