Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an ultrapure water reverse osmosis treatment device. Background Art

[0002] Reverse osmosis technology is the most advanced and effective membrane separation technology today. Its principle is to separate substances and water under the action of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. When performing reverse osmosis treatment on liquids, an ultrapure water reverse osmosis treatment device is required.

[0003] The processing device in the prior art cannot conveniently disassemble and replace multiple filter plates. When performing reverse osmosis treatment on the liquid, the filter plate needs to be used first to perform initial filtration treatment on the liquid, thereby reducing the filtration burden of the reverse osmosis membrane filter element. However, the processing device in the prior art cannot conveniently disassemble and replace the filter plate. Since the filter plate will inevitably be damaged or dirty after long-term use, it needs to be disassembled and replaced. If it is not disassembled and replaced, the filtration effect of the filter plate will be greatly reduced, thereby affecting the reverse osmosis treatment effect and efficiency of the processing device for the liquid, and further increasing the filtration burden of the reverse osmosis membrane filter element. In addition, after the reverse osmosis membrane filter element has been used for a long time, the reverse osmosis membrane filter element will also be damaged. At this time, if the reverse osmosis membrane filter element cannot be disassembled and replaced, it will also affect the reverse osmosis treatment effect of the processing device on the liquid.

[0004] Compared with the Chinese patent with publication number CN213537468U, the utility model relates to the field of water treatment technology, and discloses a reverse osmosis device for ultrapure water treatment system, including a shell, a first cavity and a second cavity are arranged inside the shell, a liquid outlet pipe is arranged at the outer end of the second cavity, and a reverse osmosis membrane is arranged in the second cavity; a liquid inlet pipe is arranged at the top of the first cavity away from the second cavity, a sewage pipe is arranged directly below the liquid inlet pipe, and a preliminary filter cartridge is inserted in the liquid inlet pipe, and the port of the preliminary filter cartridge is fixed with a mounting block through a connecting rod, and a rotating shaft is rotatably installed at the bottom end of the mounting block, and a spiral blade is arranged at the upper end of the rotating shaft, and bristles are arranged on the rotating shaft. Before the reverse osmosis filtration is performed, the device first filters the liquid by the preliminary filter cartridge to remove impurities with larger internal volume, thereby reducing the filtration burden of the reverse osmosis membrane.

[0005] The above scheme can easily reduce the filtering burden of the reverse osmosis membrane, but after the filter plate and the reverse osmosis membrane have been used for a long time, it is still impossible to effectively disassemble and replace the filter plate and the reverse osmosis membrane, and fails to solve the problems raised in the above background technology.

[0006] In view of this, we propose an ultrapure water reverse osmosis treatment device. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1 - Figure 5 as shown, this embodiment provides an ultra-pure water reverse osmosis treatment device, including a base 1, and further including:

[0029] A filter cylinder 3 is fixedly connected to the upper surface of the base 1 through a first support frame 2. A sealing cover 4 is provided above the filter cylinder 3. A rotating rod 12 is provided inside the filter cylinder 3. The bottom end of the rotating rod 12 is fixedly connected to a limiting disc 13. A plurality of filter nets 14 are fixedly connected to the outside of the rotating rod 12, and a cleaning brush 15 is fixedly connected to the outside of each of the plurality of filter nets 14;

[0030] A processing box 5 is fixedly connected to the upper surface of the base 1. A plurality of filter plates 17 are provided inside the processing box 5. The processing box 5 and the filter cylinder 3 are connected and communicated through a first water pump 21 and a pipeline;

[0031] A positioning component is arranged inside the processing box 5 and is used for positioning and installing a plurality of filter plates 17, so as to facilitate the user to disassemble, replace and install the plurality of filter plates 17;

[0032] The treatment cylinder 7 is fixedly connected to the upper surface of the base 1 through the second support frame 6. A mounting plate 23 is provided above the treatment cylinder 7. A reverse osmosis membrane filter element 26 is fixedly connected to the bottom of the mounting plate 23. The treatment cylinder 7 is connected to the treatment box 5 through a second water pump 22 and a pipeline. The bottom of the treatment cylinder 7 is connected to a drain pipe 28 through a solenoid valve 27.

[0033] The connecting assembly is symmetrically arranged outside the treatment cylinder 7 and is used for disassembling and installing the reverse osmosis membrane filter element 26 .

[0034] The above working principle: when it is necessary to perform reverse osmosis treatment on the liquid, it is only necessary to first add the liquid into the filter cartridge 3. At this time, the filter screen 14 inside the filter cartridge 3 can effectively perform the initial filtration treatment on the liquid, thereby reducing the larger impurities in the liquid. After the initial filtration of the liquid is completed, the first water pump 21 starts to run. At this time, the liquid in the filter cartridge 3 will be pumped into the treatment box 5. The multiple filter plates 17 inside the treatment box 5 can effectively perform the second filtration treatment on the liquid. After the liquid filtration is completed, the second water pump 22 starts to run. At this time, the liquid in the treatment box 5 will be pumped into the treatment cartridge 7, and then pass through the inside of the treatment cartridge 7. The reverse osmosis membrane filter element 26 is filtered, which not only improves the reverse osmosis filtration effect of the liquid, but also effectively reduces the filtration burden of the reverse osmosis membrane filter element 26. When the filter plate 17 needs to be disassembled and replaced, the filter plate 17 can be easily taken out from the inside of the treatment box 5 through the positioning component, so that the user can replace the filter plate 17 conveniently. When the reverse osmosis membrane filter element 26 needs to be disassembled and replaced, the reverse osmosis membrane filter element 26 can be easily taken out from the inside of the treatment cylinder 7 through the connecting component, so that the user can disassemble and replace the reverse osmosis membrane filter element 26 conveniently, saving time and effort.

[0035] In order to conveniently disassemble the sealing cover 4 and the filter cartridge 3, thereby facilitating the cleaning of the filter screen 14 and the cleaning brush 15, a first fixing ring 10 is fixedly connected to the outside of the sealing cover 4, and a second fixing ring 11 is fixedly connected to the outside of the filter cartridge 3. The first fixing ring 10 and the second fixing ring 11 are fixedly connected by bolts. When the filter screen 14 and the cleaning brush 15 need to be cleaned, it is only necessary to unscrew the bolts and then separate the first fixing ring 10 and the second fixing ring 11. At this time, the sealing cover 4 can be opened, so that the user can disassemble and clean the filter screen 14 and the cleaning brush 15 conveniently.

[0036] Considering that when the liquid is subjected to reverse osmosis filtration treatment, it is necessary to remove the larger impurities in the liquid first, so the upper surface of the sealing cover 4 is fixedly connected with a driving box 8, one side of the driving box 8 is fixedly connected with a driving motor 9, the output shaft of the driving motor 9 is fixedly connected with a driving rod 29 through a coupling, the other end of the driving rod 29 is fixedly connected with a first bevel gear 30, the top end of the rotating rod 12 is rotatably connected with the inner top end of the driving box 8, and the outer side of the rotating rod 12 is fixedly connected with a second bevel gear 31 meshing with the first bevel gear 30. When the liquid needs to be filtered for the first time, it only needs to be added into the filter cartridge 3 first. At this time The driving motor 9 starts to run, driving the driving rod 29 to rotate synchronously, the driving rod 29 drives the first bevel gear 30 to rotate synchronously, the first bevel gear 30 drives the second bevel gear 31 to rotate synchronously, the second bevel gear 31 drives the rotating rod 12 to rotate synchronously, and the rotating rod 12 drives the filter screen 14 to rotate synchronously. At this time, the liquid can be initially filtered through the filter screen 14, thereby reducing the larger impurities contained in the liquid. During the rotation of the filter screen 14, the cleaning brush 15 is also driven to rotate synchronously. At this time, the cleaning brush 15 can effectively clean the impurities adhered to the inner wall of the filter cylinder 3.

[0037] In order to effectively filter the liquid and reduce the filtering burden of the reverse osmosis membrane filter element 26, the multiple filter plates 17 are, from left to right, a quartz sand filter plate 17, an activated carbon filter plate 17 and a resin filter plate 17. Through the cooperation between the quartz sand filter plate 17, the activated carbon filter plate 17 and the resin filter plate 17, the filtering effect of the device on the liquid can be effectively improved. On the one hand, the device can effectively filter the liquid, and on the other hand, it can effectively reduce the filtering burden of the reverse osmosis membrane filter element 26.

[0038] In order to conveniently disassemble the filter plate 17, so as to facilitate the user to replace the filter plate 17, the positioning component includes a plurality of U-shaped plates 16 fixedly connected to the inner bottom end of the processing box 5. The upper surfaces of the plurality of U-shaped plates 16 are all provided with guide grooves for the filter plate 17 to move. The upper surface of the processing box 5 is provided with a plurality of guide grooves for the filter plate 17 to move. The upper surfaces of the plurality of filter plates 17 are all fixedly connected with connecting plates 18. The bottoms of the plurality of connecting plates 18 are symmetrically provided with insertion blocks 19. The front surface and the rear surface of the processing box 5 are both fixedly connected with a plurality of clamping blocks 20. The upper surfaces of the plurality of clamping blocks 20 are all provided with guide grooves for the insertion blocks 19 to move. When it is necessary to disassemble the filter plate 17, only need to pull the connecting plate 18. At this time, the connecting plate 18 will drive the insertion block 19 to move synchronously. The connecting plate 18 will also drive the filter plate 17 to move synchronously. When the insertion block 19 is pulled out from the guide groove opened on the upper surface of the clamping block 20, the filter plate 17 can be pulled out from the guide groove on the upper surface of the U-shaped plate 16. At this time, the filter plate 17 can be disassembled, so as to facilitate the user to replace it.

[0039] In addition, in order to conveniently disassemble and replace the reverse osmosis membrane filter element 26, the connecting component includes connecting blocks 25 symmetrically arranged outside the processing cylinder 7. The bottom of the mounting disc 23 is symmetrically provided with mounting blocks 24. The upper surfaces of the two connecting blocks 25 are both provided with guide grooves for the mounting blocks 24 to move. The two mounting blocks 24 and the connecting blocks 25 are fixedly connected by bolts. When it is necessary to disassemble the reverse osmosis membrane filter element 26, only need to unscrew the bolts and then pull the mounting disc 23. At this time, the mounting disc 23 will drive the mounting blocks 24 to move synchronously. When the mounting blocks 24 are pulled out from the guide grooves opened on the upper surfaces of the connecting blocks 25, the reverse osmosis membrane filter element 26 can be pulled out from the inside of the processing cylinder 7. At this time, the reverse osmosis membrane filter element 26 can be disassembled, so as to facilitate the user to replace it.
