Description

Technical Field

[0001] The present invention relates to the technical field of wastewater deep purification devices, and specifically to a wastewater deep purification device and a purification ultrafiltration system. Background Art

[0002] The deep purification of wastewater includes multiple processes, and the main pollutants to be removed in each process are also different. When filtering in the ultrafiltration system, mainly macromolecular pollutants in the wastewater are filtered and separated.

[0003] Chinese Patent CN113800601B discloses a tubular ultrafiltration membrane wastewater purification device, in which a filtering component extending towards both ends is arranged inside the housing, and a dual-purpose pipe is connected to the top of the filtering component. The dual-purpose pipe is also connected to a circulation component, and the housing can be backwashed during the working process.

[0004] In the above patent and the prior art, when the ultrafiltration membrane works for a long time, the filtered pollutants will block the filtering holes on the ultrafiltration membrane, thus seriously affecting the filtering efficiency. And the process of replacing the ultrafiltration membrane is rather cumbersome, and the deep purification work of wastewater also needs to be stopped. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a wastewater deep purification device and a purification ultrafiltration system.

[0006] A wastewater deep purification device and a purification ultrafiltration system, including a sewage tank, a partitioning mechanism, and a fixing mechanism. The fixing mechanism is installed at the bottom of the partitioning mechanism. An inlet is provided at the top of the sewage tank, and an outlet is provided at the bottom of the sewage tank. The partitioning mechanism is installed inside the outlet, and a filtering mechanism is installed inside the partitioning mechanism;

[0007] The top of the filtering mechanism passes through the partitioning mechanism and extends into the sewage tank. The outside of the filtering mechanism is clamped with the fixing mechanism. The inside of the sewage tank is communicated with the partitioning mechanism through the filtering mechanism;

[0008] The partitioning mechanism includes a lower sealing ring and a sealing cover plate. The sealing cover plate is installed at the top of the filtering mechanism. When the filtering mechanism descends, it can drive the sealing cover plate to descend and be clamped with the lower sealing ring;

[0009] The sewage inside the sewage tank can flow out from the separation mechanism through the filtering mechanism. The filtering mechanism can deeply purify the sewage passing through it. The outside of the filtering mechanism is slidably connected to the inside of the separation mechanism. The fixing mechanism can release the fixation of the filtering mechanism. When the filtering mechanism slides inside the separation mechanism, it can drive the sealing cover plate to rotate and engage with the lower sealing ring. When the sealing cover plate engages with the lower sealing ring, it can seal the top of the separation mechanism. When the sealing cover plate rotates, it can separate the sealing cover plate from the filtering mechanism, and then remove the filtering mechanism from the inside of the separation mechanism to replace the filtering mechanism.

[0010] Preferably, the separation mechanism includes a separation plate, which is fixedly installed on the inner side wall of the water outlet. A lower sealing ring is installed on the top of the separation plate. A sealing groove is formed on the outside of the lower sealing ring. A sealing block is fixedly installed on the outside of the sealing cover plate. A connecting sleeve is installed inside the sealing cover plate. A connecting sleeve is formed inside the connecting sleeve. A magnetic attracting block is fixedly installed inside the connecting sleeve.

[0011] Preferably, a plurality of filtering installation holes are formed inside the separation plate. A limiting block is fixedly installed inside each of the plurality of filtering installation holes. The filtering mechanism is slidably installed inside each of the filtering installation holes. A corresponding lower sealing ring is provided at the top of each of the plurality of filtering installation holes;

[0012] The outside of the filtering mechanism is slidably installed inside the filtering installation hole under the restriction of the limiting block. The bottom of the sealing cover plate is clamped to the top of the filtering mechanism through the connecting sleeve.

[0013] Preferably, the process of the sealing block engaging with the sealing groove inside the lower sealing ring is divided into an inclined section and a horizontal section. The process of the filtering mechanism engaging with the connecting groove on the connecting sleeve is also divided into an inclined section and a horizontal section;

[0014] When the filtering mechanism descends and the sealing block passes through the inclined section of the sealing groove, it can drive the sealing cover plate to rotate. At this time, the engagement of the filtering mechanism with the connecting groove passes through the horizontal section and enters the inclined section. When the filtering mechanism continues to descend and passes through the inclined section of the engagement with the connecting groove, it continues to drive the sealing cover plate to rotate. When the sealing cover plate continues to rotate, it can drive the sealing block to engage with the horizontal section of the sealing groove.

[0015] Preferably, the filtering mechanism includes a filtering housing which is slidably installed inside the filtering installation hole. A filtering connection column is fixedly installed at the top of the filtering housing. A filtering connection block is fixedly installed on the outside of the filtering connection column. A filtering limit ring is fixedly installed on the outside of the filtering housing. A limit sliding groove is opened on the outside of the filtering housing. A sewage partition plate is fixedly installed inside the filtering housing. A sewage ultrafiltration pipe is fixedly installed inside the sewage partition plate. A filtering drain opening is opened at the bottom of the filtering housing;

[0016] The outside of the filtering housing is clamped and slidably installed inside the filtering installation hole through the limit sliding groove and a limit block inside the filtering installation hole.

[0017] Preferably, the filtering housing is provided with a water inlet only in the upper half section. The sewage partition plate can separate the upper half section with the water inlet and the closed lower half section of the filtering housing. The top of the sewage ultrafiltration pipe is fixedly connected to the top inside the filtering housing. The bottom of the sewage ultrafiltration pipe passes through the sewage partition plate and extends into the lower half section of the filtering housing;

[0018] The upper half section and the lower half section of the filtering housing are communicated through the sewage ultrafiltration pipe. The sewage ultrafiltration pipe can deeply purify the wastewater when the wastewater passes through.

[0019] Preferably, the outside of the filtering connection column is clamped with a connection card slot on the filtering limit ring through the filtering connection block. There is a notch at the top of the filtering connection column. The suction force between the magnetic attraction block and the filtering connection column can drive the sealing cover plate to rotate on the filtering connection column.

[0020] Preferably, the fixing mechanism includes a limit handle and a connection spring. The limit handle is slidably installed at the bottom of the partition plate. A filtering limit ring is fixedly installed inside the limit handle. Spring connection blocks are fixedly installed on both sides of the limit handle. The spring connection blocks are connected to the partition plate through the connection spring.

[0021] Preferably, the filtering limit ring is slidably installed at the bottom of the partition plate through the limit handle. The filtering limit ring outside the filtering housing is installed inside the partition plate through the limitation of the filtering limit ring;

[0022] When the bottom of the filtering limit ring contacts the filtering limit ring, the position of the filtering housing can be fixed. When the filtering limit ring is separated from the filtering limit ring by sliding, the filtering housing can slide inside the filtering installation hole.

[0023] Compared with the prior art, the present invention provides a wastewater deep purification device and a purification ultrafiltration system, which have the following beneficial effects:

[0024] 1. For this advanced wastewater purification device, when disassembling the filtration mechanism, the downward movement of the filtration mechanism can drive the sealing cover plate to rotate counterclockwise. When the sealing cover plate rotates counterclockwise, the sealing cover plate can be engaged with the lower sealing ring to seal the filtration installation hole and separate from the filtration mechanism. When installing the filtration mechanism, the upward movement of the filtration mechanism drives the sealing cover plate to rotate clockwise. When the sealing cover plate rotates clockwise, it can drive the disconnection from the lower sealing ring and engage with the filtration mechanism, enabling the rapid replacement of the filtration mechanism during the working process and preventing the pollutant blockage of the filtration holes on the ultrafiltration membrane due to long-term operation.

[0025] 2. For this advanced wastewater purification device, the inclined section and the horizontal section are respectively arranged on the sealing card slot and the connection card slot. When the filtration mechanism moves up and down, it can drive the sealing cover plate to rotate in different directions according to the different positions of the sealing block and the filtration connection block. When installing and disassembling during the up and down movement of the filtration mechanism, it can automatically drive the sealing cover plate to connect and separate from the lower sealing ring. When the sealing cover plate is connected to the lower sealing ring, it can seal the filtration installation hole to prevent the unpurified sewage from flowing out of the filtration installation hole.

[0026] 3. For this advanced wastewater purification device, during the working process, the position of the filtration mechanism is fixed by the clamping of the filtration limiting ring and the partition plate to the filtration limiting ring. During the disassembly and assembly process, only by pulling the limiting handle can the filtration limiting ring be separated from the filtration limiting ring, thus quickly completing the disassembly, assembly, and replacement of the filtration mechanism.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a wastewater deep purification device and a purification ultrafiltration system.

[0040] Embodiment 1:

[0041] Please refer to Figure 1 - Figure 10 , a wastewater deep purification device, including a sewage tank 1, a partition mechanism 4 and a fixing mechanism 6. The fixing mechanism 6 is installed at the bottom of the partition mechanism 4. A water inlet 2 is opened at the top of the sewage tank 1, a water outlet 3 is opened at the bottom of the sewage tank 1, the partition mechanism 4 is installed inside the water outlet 3, and a filtering mechanism 5 is installed inside the partition mechanism 4;

[0042] The top of the filtering mechanism 5 passes through the separating mechanism 4 and extends into the interior of the sewage tank 1. The exterior of the filtering mechanism 5 is snap-connected to the fixing mechanism 6. The interior of the sewage tank 1 is communicated with the separating mechanism 4 through the filtering mechanism 5.

[0043] The separating mechanism 4 includes a lower sealing ring 44 and a sealing cover plate 46. The sealing cover plate 46 is installed on the top of the filtering mechanism 5. When the filtering mechanism 5 descends, it can drive the sealing cover plate 46 to descend and be snap-connected to the lower sealing ring 44.

[0044] The sewage inside the sewage tank 1 can flow out from the separating mechanism 4 through the filtering mechanism 5. The filtering mechanism 5 can deeply purify the sewage passing through. The exterior of the filtering mechanism 5 is slidably connected to the interior of the separating mechanism 4. The fixing mechanism 6 can release the fixation of the filtering mechanism 5. When the filtering mechanism 5 slides inside the separating mechanism 4, it can drive the sealing cover plate 46 to rotate and be snap-connected to the lower sealing ring 44. When the sealing cover plate 46 is snap-connected to the lower sealing ring 44, it can seal the top of the separating mechanism 4. When the sealing cover plate 46 rotates, the sealing cover plate 46 can be separated from the filtering mechanism 5, and then the filtering mechanism 5 can be removed from the interior of the separating mechanism 4 to replace the filtering mechanism 5.

[0045] During operation, first, the wastewater is injected into the interior of the sewage tank 1 through the water inlet 2. After the wastewater enters the interior of the filtering mechanism 5, the filtering mechanism 5 can deeply purify the wastewater. The purified wastewater is discharged from the bottom of the filtering mechanism 5. During long-term operation, the pollutants accumulated inside the filtering mechanism 5 increase and the purification efficiency decreases. Then, the fixing mechanism 6 releases the fixation of the filtering mechanism 5 to replace the filtering mechanism 5. When the filtering mechanism 5 descends, it can drive the sealing cover plate 46 to move downward, and during the process of the filtering mechanism 5 driving the sealing cover plate 46 to descend, it can also drive the sealing cover plate 46 to rotate. When the sealing cover plate 46 rotates, it can be snap-connected to the lower sealing ring 44 to seal the filtering installation hole 42. And after the lower sealing ring 44 rotates, the sealing cover plate 46 can be separated from the filtering mechanism 5 to prevent the wastewater from flowing out of the filtering installation hole 42 during the replacement of the filtering mechanism 5. When the new filtering mechanism 5 is slidably installed, the top of the filtering mechanism 5 is disengaged from the sealing cover plate 46, and the sealing cover plate 46 is driven to rotate again, so that the sealing cover plate 46 is snap-connected to the top of the filtering mechanism 5. Then, the position of the filtering mechanism 5 is fixed through the fixing mechanism 6, and the replacement of the filtering mechanism 5 can be completed. This device can replace the filtering mechanism 5 without interrupting the deep purification of wastewater during the working process, preventing the filtering holes on the ultrafiltration membrane from being blocked by pollutants during long-term operation of the ultrafiltration membrane.

[0046] Embodiment 2:

[0047] Please refer to Figure 2 - Figure 6, different from the above embodiments, the separating mechanism 4 includes a separating plate 41, the separating plate 41 is fixedly installed on the inner side wall of the water outlet 3, a lower sealing ring 44 is installed on the top of the separating plate 41, a sealing groove 45 is formed on the outside of the lower sealing ring 44, a sealing block 47 is fixedly installed on the outside of the sealing cover plate 46, a connecting sleeve 48 is installed inside the sealing cover plate 46, and a magnetic attraction block 410 is fixedly installed inside the connecting sleeve 48.

[0048] A plurality of filter installation holes 42 are formed inside the separating plate 41, a limit block 43 is fixedly installed inside each of the plurality of filter installation holes 42, a filter mechanism 5 is slidably installed inside each of the filter installation holes 42, and a corresponding lower sealing ring 44 is arranged at the top of each of the plurality of filter installation holes 42;

[0049] The outside of the filter mechanism 5 is slidably installed inside the filter installation hole 42 under the restriction of the limit block 43, and the bottom of the sealing cover plate 46 is clamped with the top of the filter mechanism 5 through the connecting sleeve 48.

[0050] The clamping process of the sealing block 47 with the sealing groove 45 inside the lower sealing ring 44 is divided into an inclined section and a horizontal section, and the clamping process of the filter mechanism 5 with the connecting groove 49 on the connecting sleeve 48 is also divided into an inclined section and a horizontal section;

[0051] When the filter mechanism 5 descends and the sealing block 47 passes through the inclined section of the sealing groove 45, it can drive the sealing cover plate 46 to rotate. At this time, the clamping of the filter mechanism 5 with the connecting groove 49 passes through the horizontal section and enters the inclined section. When the filter mechanism 5 continues to descend, it continues to drive the sealing cover plate 46 to rotate through the inclined section of the connection with the connecting groove 49. When the sealing cover plate 46 continues to rotate, it can drive the sealing block 47 to be clamped with the horizontal section of the sealing groove 45.

[0052] When disassembling the filtering mechanism 5, the filtering mechanism 5 moves downward. During the downward movement of the filtering mechanism 5, it drives the sealing cover plate 46 to move downward synchronously. When the sealing cover plate 46 descends, the sealing block 47 first contacts the inclined section of the sealing slot 45. When the sealing cover plate 46 drives the sealing block 47 to descend along the inclined section of the sealing slot 45, it can drive the sealing cover plate 46 to rotate counterclockwise. When the sealing cover plate 46 rotates, the filtering connection block 53 also moves from the horizontal section of the connection slot 49 to the inclined section of the connection slot 49. The filtering mechanism 5 continues to drive the position of the sealing cover plate 46 to descend, and the filtering connection block 53 slides along the inclined section of the connection slot 49 to continue driving the sealing cover plate 46 to rotate counterclockwise. When the sealing cover plate 46 rotates counterclockwise, it drives 47 to be clamped with the sealing slot 45 to seal the top of the filtering installation hole 42. Then, the filtering connection column 52 is separated from the sealing cover plate 46, and the filtering mechanism 5 is removed from the inside of the filtering installation hole 42. When installing the filtering mechanism 5, the filtering mechanism 5 moves upward. When the filtering mechanism 5 moves upward, the filtering connection column 52 is inserted into the inside of the connection sleeve 48. Then, the filtering connection block 53 enters the inclined section of the connection slot 49. When the filtering connection block 53 moves upward along the inclined section of the connection slot 49, it can drive the sealing cover plate 46 to rotate clockwise. When the sealing cover plate 46 rotates clockwise, it can drive the sealing block 47 to release the clamping with the sealing slot 45. Then, through the mutual attraction between the filtering connection column 52 and the magnetic attraction block 410, the sealing cover plate 46 is driven to continue rotating clockwise. Then, the filtering mechanism 5 continues to move upward until the filtering limit ring 54 contacts the partition plate 41. Then, the position of the filtering mechanism 5 is fixed by the fixing mechanism 6. When the filtering mechanism 5 moves up and down inside the filtering installation hole 42, the limit block 43 is clamped with the limit sliding groove 55, which can prevent the limit sliding groove 55 from rotating during the up and down movement. When the filtering mechanism 5 is installed and disassembled during the up and down movement, it can automatically drive the sealing cover plate 46 to connect and separate from the lower sealing ring 44. When the sealing cover plate 46 is connected to the lower sealing ring 44, it can seal the filtering installation hole 42 to prevent the unpurified sewage from flowing out of the filtering installation hole 42.

[0053] Embodiment 3:

[0054] Please refer to Figure 6 - Figure 10 which is different from the above embodiment in that the filtering mechanism 5 includes a filtering housing 51, the filtering housing 51 is slidably installed inside the filtering installation hole 42, a filtering connection column 52 is fixedly installed at the top of the filtering housing 51, a filtering connection block 53 is fixedly installed outside the filtering connection column 52, a filtering limit ring 54 is fixedly installed outside the filtering housing 51, a limit sliding groove 55 is opened outside the filtering housing 51, a sewage partition plate 57 is fixedly installed inside the filtering housing 51, a sewage ultrafiltration pipe 56 is fixedly installed inside the sewage partition plate 57, and a filtering drain port 58 is opened at the bottom of the filtering housing 51;

[0055] The outside of the filter housing 51 is clamped and slidably installed inside the filter mounting hole 42 through the limit chute 55 and the limit block 43 inside the filter mounting hole 42.

[0056] The filter housing 51 is only provided with a water inlet in the upper half. The sewage partition plate 57 can separate the upper half with the water inlet and the closed lower half of the filter housing 51. The top of the sewage ultrafiltration tube 56 is fixedly connected to the top inside the filter housing 51, and the bottom of the sewage ultrafiltration tube 56 passes through the sewage partition plate 57 and extends into the lower half of the filter housing 51;

[0057] The upper half and the lower half of the filter housing 51 are communicated through the sewage ultrafiltration tube 56, and the sewage ultrafiltration tube 56 can deeply purify the wastewater when the wastewater passes through.

[0058] The outside of the filter connection column 52 is clamped with the connection card slot 49 on the filter limit ring 54 through the filter connection card block 53. There is a notch at the top of the filter connection column 52, and the suction force between the magnetic attraction card block 410 and the filter connection column 52 can drive the sealing cover plate 46 to rotate on the filter connection column 52.

[0059] The fixing mechanism 6 includes a limit handle 61 and a connecting spring 64. The limit handle 61 is slidably installed at the bottom of the partition plate 41. The filter limit ring 62 is fixedly installed inside the limit handle 61. Spring connection blocks 63 are fixedly installed on both sides of the limit handle 61, and the spring connection blocks 63 are connected to the partition plate 41 through the connecting spring 64.

[0060] The filter limit ring 62 is slidably installed at the bottom of the partition plate 41 through the limit handle 61, and the filter limit ring 54 outside the filter housing 51 is installed inside the partition plate 41 through the limitation of the filter limit ring 62;

[0061] When the bottom of the filter limit ring 62 contacts the filter limit ring 54, the position of the filter housing 51 can be fixed. When the filter limit ring 62 is separated from the filter limit ring 54 by sliding, the filter housing 51 can slide inside the filter mounting hole 42.

[0062] When the sewage is deeply purified, the sewage enters the interior of the filter housing 51 from the water inlet at the upper half of the filter housing 51. After entering the interior of the filter housing 51, the sewage ultrafiltration tube 56 in the sewage can isolate the macromolecular pollutants in the sewage outside the sewage ultrafiltration tube 56. The relatively clean water flow then passes through the sewage ultrafiltration tube 56, through the sewage partition plate 57, into the lower half of the filter housing 51, and then is discharged through the filter drain port 58. The position of the filter housing 51 is fixed by the snap connection of the filter limit ring 62 and the partition plate 41 to the filter limit ring 54. During the disassembly and assembly process, only by pulling the limit handle 61 can the filter limit ring 62 be separated from the filter limit ring 54, so as to quickly complete the disassembly, replacement and installation of the filter mechanism 5.

[0066] Then, the sewage is deeply purified by the filter mechanism 5, and the purified sewage is discharged from the water outlet 3;

[0067] After the fixing mechanism 6 releases the fixation of the filter mechanism 5, the filter mechanism 5 can be moved downward. When the filter mechanism 5 descends, it can drive the sealing cover plate 46 to rotate counterclockwise. When the sealing cover plate 46 rotates counterclockwise, the sealing block 47 can be engaged with the sealing slot 45, and drive the connecting sleeve 48 to be separated from the filter mechanism 5, so as to remove the limit sliding groove 55;

[0068] Then, move the replaced filter mechanism 5 upward. When the limit sliding groove 55 moves upward, it can drive the sealing cover plate 46 to rotate clockwise.
