[0013] In a second aspect, a method for treating drinking water byproducts is provided, comprising the following steps: Step 1: Drinking water is injected into the water injection chamber. The drinking water passes through the activated carbon filter chamber, drainage assembly, intermediate filter chamber, annular semipermeable membrane, liquid storage chamber and water hole in sequence and then enters the drainage chamber. The activated carbon in the activated carbon filter chamber will perform primary filtration on the by-products in the drinking water, and the annular semipermeable membrane will perform secondary filtration on the by-products in the drinking water. Step 2: After filtering for a period of time, stop injecting water into the water injection chamber, connect the middle filter chamber with the outside of the base through the drainage component, and the water in the middle filter chamber will flow out. The drinking water stored in the liquid storage chamber will enter the middle filter chamber after being filtered through the annular semipermeable membrane. The flow of water will backflow and clean the annular semipermeable membrane, and the cleaned filter material will be discharged through the drainage component, thereby cleaning the filter material inside the middle filter chamber. Step 3: After the cleaning is completed, the connection with the outside of the base is cancelled through the drainage component to restore the working state of the filter, avoiding the need to remove the filter body for cleaning.

[0014] Compared with the prior art, the drinking water byproduct treatment device and treatment method described in the present invention have the following advantages: (1) When it is necessary to clean the impurities filtered out of the middle filter chamber, the middle filter chamber is connected to the outside of the base through the drainage component, and the drinking water in the middle filter chamber will flow out. The drinking water stored in the liquid storage chamber will enter the middle filter chamber after being filtered through the annular semipermeable membrane. The flow of water will backflow clean the annular semipermeable membrane, and the cleaned filtered material will be discharged through the drainage component, thereby cleaning the filtered material inside the middle filter chamber. During the entire cleaning process, there is no need to remove the filter body. The annular semipermeable membrane can be cleaned by the backflow of filtered water, which provides convenience for the staff to clean the filter body. In addition, the water flowing out of the drainage component flows downward from the top of the middle filter chamber. The downward flow of water will flow through the inner ring surface of the annular semipermeable membrane, driving the filtered material, which is conducive to thorough cleaning of the filtered material.

[0015] (2) According to the present invention, before removing the blockage from the bottom end of the drainage tube, the rotating seat is rotated, the rotating seat drives the drainage tube to rotate, the drainage tube drives the connecting frame to rotate, and the connecting frame simultaneously drives the two scrapers to scrape along the inner wall of the annular semipermeable membrane. On the one hand, the filtered matter adhering to the inner wall of the annular semipermeable membrane is preliminarily cleaned to reduce adhesion and facilitate subsequent discharge. On the other hand, the amount of filtered matter adhering to the inner wall of the annular semipermeable membrane is reduced, thereby reducing the difficulty of subsequent backflow cleaning.

[0016] During the sewage discharge process, the flow of both the water outlet pipe and the water inlet pipe is stopped, and the pressing seat is pushed upward. The pressing seat pushes the annular plug body through the pushing rod, and the annular plug body moves in the flow-pushing chamber, thereby pressurizing the water in the liquid storage chamber, so that the water in the liquid storage chamber flows back through the annular semipermeable membrane, flushing out the filtrate blocked in the annular semipermeable membrane, and then draining it away with the water in the middle filter chamber. On the one hand, countercurrent cleaning is achieved, and on the other hand, the driving force will accelerate the flow of water, which is conducive to taking away the filtrate.

[0017] In the process of pushing the pressing seat, the pressing seat will push the linkage ring to move through the pushing rod, and the linkage ring will drive the two gas springs to move. Before the linkage ring contacts the annular plug body, the pressing handle will apply pressure to the pressure sensor under external force. The pressure sensor will send a request message, requesting the controller to control the motor to start. The motor will indirectly drive the rotating seat to rotate, and then drive the sealing plug to rotate. The sealing plug will drive the drainage tube to rotate, and then drive the scraper to scrape and clean the inside of the annular semipermeable membrane, so as to achieve scraping and cleaning before backflow cleaning. Then, when the linkage ring contacts the annular plug body, the closing ring seals the water hole above. After sealing the water hole, the linkage ring will push the annular plug body to move and push the water in the liquid storage chamber, so as to push the water in the liquid storage chamber into the middle filter chamber. Before backflow cleaning, the water in the liquid storage chamber is restricted from being discharged from the water hole, and the inner wall of the annular semipermeable membrane is scraped and cleaned in advance, providing good conditions for backflow cleaning.

The water hole 7 connects the drainage chamber 102 with the liquid storage chamber 6. It also includes a drainage component, which is arranged between the middle filter chamber 5, the activated carbon filter chamber 3 and the base 2. When filtering, the water passing through the activated carbon filter chamber 3 is drained into the middle filter chamber 5. When cleaning the annular semipermeable membrane 4, the bottom end of the middle filter chamber 5 is connected to the outside of the base 2.

[0025] The cover 101 is also connected to a water inlet pipe 8 and a water outlet pipe 9. The water inlet pipe 8 is connected to the water injection chamber 103, and the water outlet pipe 9 is connected to the drainage chamber 102. It should be understood that drinking water is injected into the water injection chamber 103 through the water inlet pipe 8, and the water in the drainage chamber 102 is discharged through the water outlet pipe 9. The filter body also includes an upper sealing ring 10 and a lower sealing ring 11. The top opening of the activated carbon filter chamber 3 is fixedly connected to the inner ring wall of the upper sealing ring 10. The upper sealing ring 10 and the lower sealing ring 11 are respectively fixedly connected to the top and bottom ends of the annular semipermeable membrane 4. The lower sealing ring 11 contacts the top of the base 2. The upper sealing ring 10 is connected to the bottom opening of the water injection chamber 103. The water in the water injection chamber 103 will pass through the upper sealing ring 10 and the top opening of the activated carbon filter chamber 3 to enter the activated carbon filter chamber 3. Two filter plates 12 are fixedly connected to the inner wall of the activated carbon filter chamber 3. Activated carbon is filled between the two filter plates 12. The water entering the activated carbon filter chamber 3 will pass through the two filter plates 12 and the activated carbon and then be discharged from the inner ring cavity of the lower sealing ring 11 to achieve activated carbon filtration. Specifically, the top of the treatment tank 1 has a lap joint 13 and a threaded docking ring 47, the outer ring surface of the threaded docking ring 47 is provided with a first threaded surface 14, the inner top surface of the cover 101 is fixedly connected with a pressing cover 15, the pressing cover 15 is pressed against the top of the upper sealing ring 10, and the inner edge of the cover 101 is provided with a second threaded surface 16. After the second threaded surface 16 is threadedly connected to the first threaded surface 14, a drainage cavity 102 is formed between the threaded docking ring 47, the cover 101 and the pressing cover 15. The top of the treatment tank 1 is provided with a water outlet 104, and the water outlet 104 is connected to the drainage cavity 102. 2 is connected, a water injection chamber 103 is formed on the inner side of the pressing cover 15, the water inlet pipe 8 passes through the cover body 101 and enters the water injection chamber 103, the water outlet pipe 9 passes through the cover body 101, the water injection chamber 103 and the pressing cover 15 in sequence and enters the drainage chamber 102, and is pressed tightly by the pressing cover 15, and the filter body enters the interior of the treatment tank 1 through the water through port 104, and the upper sealing ring 10 overlaps in the overlap port 13. It should be understood that the filter body is installed in the treatment tank 1 by clamping the pressing cover 15 and the base 2, and when maintenance is needed, the filter body can be directly taken out by unscrewing the cover body 101, which is convenient for operation.

[0026] The specific by-product treatment method is as follows: Step 1: Drinking water is injected into the water injection chamber 103. The drinking water passes through the activated carbon filter chamber 3, the drainage assembly, the intermediate filter chamber 5, the annular semipermeable membrane 4, the liquid storage chamber 6 and the water through hole 7 in sequence and then enters the drainage chamber 102. The activated carbon in the activated carbon filter chamber 3 will perform primary filtration on the by-products in the drinking water, and the annular semipermeable membrane 4 will perform secondary filtration on the by-products in the drinking water. Step 2: After filtering for a period of time, stop injecting water into the water injection chamber 103, connect the intermediate filter chamber 5 with the outside of the base 2 through the drainage component, and the water in the intermediate filter chamber 5 will flow out. The drinking water stored in the liquid storage chamber 6 will enter the intermediate filter chamber 5 after being filtered by the annular semipermeable membrane 4. The flow of water will perform countercurrent cleaning on the annular semipermeable membrane 4, and the cleaned filtered matter will be discharged through the drainage component, thereby cleaning the filtered matter inside the intermediate filter chamber 5. Step 3: After the cleaning is completed, the connection with the outside of the base 2 is cancelled through the drainage component to restore the filtering working state, avoiding the need to remove the filter body for cleaning.

[0027] It can be seen from the above-mentioned treatment method that when it is necessary to clean the impurities filtered out of the intermediate filter chamber 5, the intermediate filter chamber 5 is connected to the outside of the base 2 through the drainage component, and the drinking water in the intermediate filter chamber 5 will flow out. The drinking water stored in the liquid storage chamber 6 will be filtered through the annular semipermeable membrane 4 and then enter the intermediate filter chamber 5. The flow of water will perform a countercurrent cleaning on the annular semipermeable membrane 4, and the cleaned filtered material will be discharged through the drainage component to achieve the cleaning of the filtered material inside the intermediate filter chamber 5. During the entire cleaning process, there is no need to remove the filter body. The annular semipermeable membrane 4 can be cleaned by the backflow of filtered water, which provides convenience for the staff to clean the filter body, and the water flowing out of the drainage component flows downward from the top of the intermediate filter chamber 5. The downward flow of water will flow through the inner annular surface of the annular semipermeable membrane 4, driving the filtered material, which is conducive to thorough cleaning of the filtered material.

[0028] like Figures 2 to 6As shown, in one embodiment, the drainage assembly includes a drainage tube 17 and a first plug-in port 18. The top end of the drainage tube 17 is rotatably connected to the bottom end of the activated carbon filter chamber 3. A one-way valve 19 is provided at the top end of the drainage tube 17. The first plug-in port 18 is provided on the base 2. The bottom end of the drainage tube 17 passes through the lower sealing ring 11 and the first plug-in port 18 and extends to the bottom of the base 2. A sealing plug 20 is provided at the bottom end of the drainage tube 17. A drainage port 21 is provided at the portion of the drainage tube 17 in the middle filter chamber 5. It should be understood that during the filtration process, the water in the water injection chamber 103 will enter the activated carbon filter chamber 3 through the water port 104 at the top of the treatment tank 1, and after being filtered by the activated carbon in the activated carbon filter chamber 3, a first-level filtration is obtained. The water filtered by the activated carbon will enter the drainage component through the one-way valve 19, and enter the intermediate filter chamber 5 under the drainage action of the drainage component. The water in the intermediate filter chamber 5 will pass through the annular semipermeable membrane 4 and obtain a secondary filtration. The water after the two-stage filtration will enter the drainage chamber 102 through the water hole 7, and the filtered water will be discharged to achieve filtration. When sewage needs to be discharged, the sealing plug 20 can be removed from the bottom end of the drainage pipe 17, and the water in the intermediate filter chamber 5 will flow into the drainage pipe 17 from the drainage port 21, and then be discharged from the bottom end of the drainage pipe 17, thereby realizing the discharge of the filtered material in the intermediate filter chamber 5.

[0029] like Figure 2 、 Figure 3 、 Figure 5 and Figure 8 As shown, in one embodiment, the bottom of the base 2 is also fixedly connected to a drainage chamber 22, and a drainage pipe 23 is connected to the side wall of the drainage chamber 22. A rotating seat 24 is rotatably mounted on the inner bottom surface of the drainage chamber 22. The bottom end of the rotating seat 24 passes through the drainage chamber 22 and extends to the outside of the drainage chamber 22. The top of the rotating seat 24 is fixedly connected to an electric cylinder 25, and the output end of the electric cylinder 25 is fixedly connected to the bottom end of the sealing plug 20. It should be understood that by activating the electric cylinder 25, the electric cylinder 25 pulls the sealing plug 20, thereby canceling the blockage of the bottom end of the drainage tube 17, allowing air to enter and drain. After the drainage is completed, the electric cylinder 25 pushes the sealing plug 20 to seal the bottom end of the drainage tube 17, thereby achieving the blockage or opening of the bottom end of the drainage tube 17, which is convenient for operation.

[0030] like Figures 2 to 6As shown, in one embodiment, a connecting frame 26 is fixedly connected to the surface of the drainage tube 17, and the connecting frame 26 is located at the bottom end of the middle filter chamber 5. Scrapers 27 are fixedly connected to both ends of the connecting frame 26. The scrapers 27 are in contact with the inner annular surface of the annular semipermeable membrane 4, and the drainage port 21 is located below the connecting frame 26. It should be understood that before the bottom end of the drainage tube 17 is unblocked, the rotating seat 24 is rotated, and the rotating seat 24 drives the drainage tube 17 to rotate, and the drainage tube 17 drives the connecting frame 26 to rotate. The connecting frame 26 synchronously drives the two scrapers 27 to scrape along the inner wall of the annular semipermeable membrane 4. On the one hand, the filtered matter adhering to the inner wall of the annular semipermeable membrane 4 is preliminarily cleaned to reduce adhesion and facilitate subsequent discharge. On the other hand, the amount of filtered matter adhering to the inner wall of the annular semipermeable membrane 4 is reduced, making it easier to clean up the backflow in the later stage.

[0031] Specifically, the tops of the two scrapers 27 are fixedly connected with connecting rings 46, and the bottom of the upper sealing ring 10 is provided with an annular groove that is slidably connected to the connecting ring 46. It should be understood that the connection between the connecting ring 46 and the annular groove supports the tops of the scrapers 27.

[0032] like Figure 2 、 Figure 3 、 Figure 5 and Figure 8 As shown, in one embodiment, a motor 28 is fixedly mounted at the bottom of the sewage chamber 22, and a driving gear 29 is fixedly connected to the output end of the motor 28. A follower gear 30 is fixedly connected to the bottom end of the rotating base 24, and the follower gear 30 is meshed with the driving gear 29. It should be understood that when it is necessary to scrape and clean the annular semipermeable membrane 4, the motor 28 is started, the motor 28 drives the driving gear 29 to rotate, the driving gear 29 drives the follower gear 30, and the follower gear 30 drives the rotating base 24 to rotate, providing scraping power to the scraper 27 in the middle filter chamber 5. This has the effect of arranging the power source outside the treatment tank 1 and providing scraping power to the scraper 27 in the middle filter chamber 5 inside the treatment tank 1.

[0033] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, a flow-pushing chamber 31 is formed between the base 2 and the inner wall of the processing tank 1, and an annular plug body 32 is slidingly arranged in the flow-pushing chamber 31. A push rod 33 is arranged at the bottom of the annular plug body 32, and the bottom end of the push rod 33 passes through the base 2 and extends to the outside of the base 2. The bottom end of the push rod 33 is fixedly connected to a pressing seat 34, and a support spring 35 is sleeved on the surface of the push rod 33. The two ends of the support spring 35 are respectively fixedly connected to the pressing seat 34 and the bottom of the base 2, and a pressure relief hole 36 connected to the flow-pushing chamber 31 is opened at the top of the base 2. It should be understood that in the process of sewage discharge, the flow of both the water outlet pipe 9 and the water inlet pipe 8 is stopped, and the pressing seat 34 is pushed upward. The pressing seat 34 pushes the annular plug body 32 through the pushing rod 33, and the annular plug body 32 moves in the flow-pushing chamber 31, thereby pressurizing the water in the liquid storage chamber 6, so that the water in the liquid storage chamber 6 flows back through the annular semipermeable membrane 4, flushing out the filtrate blocked in the annular semipermeable membrane 4, and then draining it away with the water in the middle filter chamber 5. On the one hand, countercurrent cleaning is achieved, and on the other hand, the driving force will accelerate the flow of water, which is conducive to taking the filtrate away.

[0034] like Figure 7 As shown, in one embodiment, a mounting groove 37 is provided at the bottom of the pressing seat 34, a pressure sensor 38 is fixedly installed in the mounting groove 37, a pressing handle 39 is inserted at the notch of the mounting groove 37, a reset spring 40 is fixedly connected between the pressing handle 39 and the mounting groove 37, a linkage ring 41 is fixedly connected to the top of the push rod 33, the linkage ring 41 is slidably connected to the surface of the base 2, two linkage rods 42 are fixedly connected to the top of the linkage ring 41, and the two linkage rods 42 are fixedly connected to the gas spring 43 after passing through the annular plug body 32, and the tops of the two gas springs 43 are fixedly connected to a closing ring 44. It should be understood that in the process of pushing the pressing seat 34, the pressing seat 34 will push the linkage ring 41 to move through the pushing rod 33, and the linkage ring 41 will drive the two gas springs 43 to move.
