Technical Field
[0001] This utility model relates to the technical field of high-tank ultrafiltration equipment, specifically an integrated flat-sheet membrane high-tank ultrafiltration device. Background Art
[0002] An ultrafiltration machine is a device that uses ultrafiltration technology to purify water. The difference between it and other water purification equipment is that it uses an ultrafiltration membrane. An ultrafiltration membrane is a microporous filter membrane with a uniform pore size and a rated pore size range of 0.01-0.001 microns. In the existing technology, the liquid lacks a pretreatment function before being filtered by the filter membrane, which leads to too much impurity being intercepted by the ultrafiltration membrane, which can easily cause blockage. At the same time, it lacks the function of quick loading and unloading of pretreatment components.
[0003] For example, the authorized patent document with application number CN202122171170.4 discloses an integrated flat-sheet membrane high-tank biochemical ultrafiltration device, belonging to the field of water purification technology. It includes a tank body, a top cover at the upper end of the tank body, the top cover being hinged to the tank body, a snap-fit mechanism installed on the side surface of the tank body, a side plate fixedly connected to the inner side wall of the tank body, a sliding groove fixedly connected to the front side surface of the side plate, a flat-sheet filter membrane being installed inside the sliding groove, and a sealing component being installed inside the top cover. The beneficial effect of this utility model is that the side plate and the sliding groove fixedly connected to the side surface of the side plate inside the tank body cooperate with the filter membrane frame snapped to the outside of the flat-sheet filter membrane, thereby making it easy to remove the flat-sheet filter membrane from the inside of the tank body. Therefore, it is convenient for users to clean, replace or repair the flat-sheet filter membrane, thereby reducing unnecessary trouble for users.
[0004] The aforementioned patent lacks a pretreatment function before the liquid is filtered by the membrane, resulting in excessive impurities being intercepted by the ultrafiltration membrane, which easily causes blockage. Therefore, we need to provide an integrated flat sheet membrane high-tank ultrafiltration device. Utility Model Content

[0023] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0024] Please see Figure 1-4 This utility model provides a technical solution: an integrated flat-sheet membrane high-tank ultrafiltration device, comprising:
[0025] The tank 2 has a drain valve 1. The top of the tank 2 is fixedly fitted with a cover plate 21 with a water inlet pipe 3. The bottom of the cover plate 21 is fixedly fitted with a filter frame 5 with an ultrafiltration membrane 4. The top of the cover plate 21 is fitted with a filter element 6 for liquid pretreatment.
[0026] The filter element 6 includes a mounting bracket 61 set on the top of the cover plate 21. A housing 62 is fixedly installed inside the mounting bracket 61. A sealing cover 63 is threaded on one side of the housing 62. A connecting pipe 64 is embedded in one side of the inner wall of the housing 62. Two filter elements 65 are sealed and installed inside the sealing cover 63. One side of the two filter elements is sealed and fitted to the inner wall of the sealing cover 63. Water supply pipes 66 are connected to both sides of the sealing cover 63.
[0027] A fitting sleeve 7 is fixedly installed on the surface of the connecting pipe 64, and a stop block 8 with a slot 9 is fixedly installed on both sides of the connecting pipe 64. A quick-release part 10 that can be quickly connected to the connecting pipe 64 is installed on the surface of the water inlet pipe 3.
[0028] In this embodiment, water flows into the housing 62 through two water supply pipes 66. The water flowing into the housing 62 passes through two filter elements 65 before entering the connecting pipe 64. The water is initially filtered by the two filter elements 65. The treated water flows into the pipe body through the inlet pipe 3. A filter frame 5 with a double-layer ultrafiltration membrane 4 is provided at the bottom of the cover plate 21 to filter the water again. After filtration, the water flows out through the drain valve 1.
[0029] When the inlet pipe 3 is connected to the connecting pipe 64, the connecting pipe 64 is inserted into one end of the inlet pipe 3, and the two pull rods 103 are pulled to engage with the slots 9 on the surfaces of the two stops 8 respectively. At this time, one end of the inlet pipe 3 will squeeze the fitting sleeve 7, causing the fitting sleeve 7 to deform. The rotating cylinder 101 can rotate on the surface of the inlet pipe 3. The inside of the rotating cylinder 101 is threaded to the surface of the inlet pipe 3. Pulling the ring body 102 will drive the two pull rods 103 away from the connecting pipe 64, which will make the one end of the inlet pipe 3 squeeze the fitting sleeve 7 more tightly and enhance the sealing effect.
[0030] The quick-release component 10 facilitates the removal of the filter element 6 and makes maintenance of the filter element 6 easier.
[0031] The quick-release part 10 includes a rotating cylinder 101 threaded onto the surface of the water inlet pipe 3. A ring 102 is movably sleeved on the surface of the rotating cylinder 101. Pull rods 103 are hinged on both sides of the ring 102. Each of the two pull rods 103 has a limiting groove 104 inside that cooperates with the stop block 8. The limiting groove 104 inside the pull rod 103 engages with the slot 9 on the surface of the stop block 8.
[0032] Specifically, when connecting the inlet pipe 3 to the connecting pipe 64, insert the connecting pipe 64 into one end of the inlet pipe 3, pull the two pull rods 103 to engage with the slots 9 on the surfaces of the two stops 8 respectively. At this time, one end of the inlet pipe 3 will squeeze the fitting sleeve 7, causing the fitting sleeve 7 to deform. The rotating cylinder 101 can rotate on the surface of the inlet pipe 3. The inside of the rotating cylinder 101 is threaded to the surface of the inlet pipe 3. Pulling the ring body 102 will drive the two pull rods 103 away from the connecting pipe 64, which will make the one end of the inlet pipe 3 squeeze the fitting sleeve 7 more tightly, enhancing the sealing effect.
[0033] Limiting rings 11 are provided on both sides of the ring body 102. Both limiting rings 11 are fixedly installed on the surface of the rotating cylinder 101, and one end of the water inlet pipe 3 is attached to the fitting sleeve 7.
[0034] Two limiting rings 11 are set on the surface of the rotating cylinder 101 to prevent the ring body 102 from detaching.
[0035] A sliding plate 12 is fixedly installed at the bottom of the mounting bracket 61. Two sliding strips 13 are fixedly installed at the bottom of the sliding plate 12. A groove 14 for sliding the two sliding strips 13 is opened at the top of the cover plate 21.
[0036] It is worth noting that two sliding strips 13 are provided at the bottom of the mounting bracket 61 to match the two sliding grooves 14 at the top of the cover plate 21, which facilitates the alignment and installation of the filter element 6.
[0037] Both sides of the top of the filter frame 5 are fixedly installed with insert plates 15. The inside of the cover plate 21 is embedded with alignment frames 16 for the two insert plates 15 to be snapped together. Two limit bolts 17 are slidably installed inside the two alignment frames 16. The inside of the insert plate 15 is provided with two threaded holes 18 that are threaded to the limit bolts 17.
[0038] The insertion plate 15 and the alignment frame 16 can be separated by rotating the limiting bolt 17 and the threaded hole 18 in the insertion plate 15, so that the ultrafiltration membrane 4 and the filter frame 5 can be maintained or replaced.
[0039] It also includes a sealing ring 19, which is installed on the inner wall of the sealing cover 63 and is used to seal one end of the two filter elements 65.
[0040] Specifically, a sealing ring 19 is set on the inner wall of the sealing cover 63, which works with the housing 62 to seal the two filter elements 65 inside the housing 62, so that the water must pass through the two filter elements 65 before it can flow out through the connecting pipe 64, and at the same time, it can facilitate the replacement of the two filter elements 65.
[0041] The fitting sleeve 7 is set as a rubber sleeve 20;
[0042] The bonding sleeve 7 is a rubber strip, which enhances the sealing performance and also has the ability to deform.
[0043] Water flows into the housing 62 through two water supply pipes 66. The water in the housing 62 passes through two filter elements 65 before entering the connecting pipe 64. The water is initially filtered by the two filter elements 65. The treated water then enters the pipe body through the inlet pipe 3. A filter frame 5 with a double-layer ultrafiltration membrane 4 is provided at the bottom of the cover plate 21 to filter the water again. After filtration, the water flows out through the drain valve 1.
[0044] When the inlet pipe 3 is connected to the connecting pipe 64, the connecting pipe 64 is inserted into one end of the inlet pipe 3, and the two pull rods 103 are pulled to engage with the slots 9 on the surfaces of the two stops 8 respectively. At this time, one end of the inlet pipe 3 will squeeze the fitting sleeve 7, causing the fitting sleeve 7 to deform. The rotating cylinder 101 can rotate on the surface of the inlet pipe 3. The inside of the rotating cylinder 101 is threaded to the surface of the inlet pipe 3. Pulling the ring body 102 will drive the two pull rods 103 away from the connecting pipe 64, which will make the one end of the inlet pipe 3 squeeze the fitting sleeve 7 more tightly, enhancing the sealing effect.
[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
