DETAILED DESCRIPTION

[0038] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

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

[0040] Embodiment 1:

[0041] See also Figure 1 - Fig.10 A wastewater deep purification device comprises a sewage tank 1, a partition mechanism 4 and a fixing mechanism 6, wherein the fixing mechanism 6 is installed at the bottom of the partition mechanism 4, a water inlet 2 is provided at the top of the sewage tank 1, a water outlet 3 is provided 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 filter mechanism 5 passes through the partition mechanism 4 and extends into the interior of the sewage tank 1. The exterior of the filter mechanism 5 is engaged with the fixing mechanism 6. The interior of the sewage tank 1 is connected with the partition mechanism 4 through the filter mechanism 5.

[0043] The partition 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 filter mechanism 5. When the filter mechanism 5 descends, it can drive the sealing cover plate 46 to descend and engage with the lower sealing ring 44.

[0044] The sewage inside the sewage tank 1 can flow out from the partition mechanism 4 through the filtering mechanism 5, and the filtering mechanism 5 can deeply purify the sewage passing through. The outside of the filtering mechanism 5 is slidably connected to the inside of the partition mechanism 4, and the fixing mechanism 6 can release the fixation of the filtering mechanism 5. When the filtering mechanism 5 slides inside the partition mechanism 4, it can drive the sealing cover plate 46 to rotate and engage with the lower sealing ring 44. When the sealing cover plate 46 is engaged with the lower sealing ring 44, the top of the partition mechanism 4 can be sealed. 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 is removed from the inside of the partition mechanism 4 to replace the filtering mechanism 5.

[0045] During operation, waste water is first injected into the sewage tank 1 through the water inlet 2. After entering the filter mechanism 5, the waste water can be deeply purified by the filter mechanism 5. The purified waste water is discharged from the bottom of the filter mechanism 5. When the filter mechanism 5 works for a long time, the accumulated pollutants in the filter mechanism 5 increase and the purification efficiency decreases. Then, the filter mechanism 5 is released from the fixing mechanism 6 and the filter mechanism 5 is replaced. When the filter mechanism 5 descends, the sealing cover plate 46 can be driven to move downward, and the sealing cover plate 46 can also be driven to rotate during the process of the filter mechanism 5 driving the sealing cover plate 46 to descend. When the sealing cover plate 46 rotates, it can be engaged with the lower sealing ring 44 to the filter mounting hole 4. 2 is sealed, and after the lower sealing ring 44 rotates, the sealing cover plate 46 can be separated from the filter mechanism 5 to prevent wastewater from flowing out of the filter installation hole 42 during the replacement of the filter mechanism 5. When the new filter mechanism 5 is slidably installed, the top of the filter mechanism 5 is released 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 clamped on the top of the filter mechanism 5, and then the position of the filter mechanism 5 is fixed by the fixing mechanism 6, so that the replacement of the filter mechanism 5 can be completed. The device can replace the filter mechanism 5 without interrupting the deep purification of wastewater during the working process, so as to prevent the ultrafiltration membrane from working for a long time and the pollutants from clogging the filter holes on the ultrafiltration membrane.

[0046] Embodiment 2:

[0047] See also Figure 2 - Figure 6The difference from the above embodiment is that the partition mechanism 4 includes a partition plate 41, which is fixedly mounted on the inner wall of the water outlet 3, a lower sealing ring 44 is mounted on the top of the partition plate 41, a sealing groove 45 is provided on the outside of the lower sealing ring 44, a sealing block 47 is fixedly mounted on the outside of a sealing cover plate 46, a connecting sleeve 48 is mounted on the inside of the sealing cover plate 46, a connecting sleeve 48 is provided on the inside of the connecting sleeve 48, and a magnetic card block 410 is fixedly mounted on the inside of the connecting sleeve 48.

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

[0049] The outside of the filter mechanism 5 is slidably installed in the inside of 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 clamping block 47 and the sealing clamping 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 and the connecting clamping 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, the sealing block 47 passes through the inclined section on the sealing slot 45 and can drive the sealing cover plate 46 to rotate. At this time, the filter mechanism 5 and the connecting slot 49 pass through the horizontal section and enter the inclined section. The filter mechanism 5 continues to descend and continues to drive the sealing cover plate 46 to rotate through the inclined section engaged with the connecting slot 49. When the sealing cover plate 46 continues to rotate, it can drive the sealing block 47 to engage with the horizontal section of the sealing slot 45.

[0052] When the filter mechanism 5 is disassembled, the filter mechanism 5 moves downward, and during the descending process of the filter mechanism 5, the sealing cover plate 46 is driven to move downward synchronously. When the sealing cover plate 46 descends, the sealing block 47 first contacts the inclined section on the sealing groove 45. When the sealing cover plate 46 drives the sealing block 47 to descend along the inclined section on the sealing groove 45, it can drive the sealing cover plate 46 to rotate counterclockwise. When the sealing cover plate 46 rotates, the filter connection block 53 also moves from the horizontal section of the connection groove 49 to the inclined section of the connection groove 49. The filter mechanism 5 continues to carry The position of the dynamic sealing cover plate 46 is lowered, and the filter connection block 53 slides along the inclined section of the connection slot 49 to continue to drive the sealing cover plate 46 to rotate counterclockwise. When the sealing cover plate 46 rotates counterclockwise, it drives 47 to engage with the sealing slot 45 to seal the top of the filter installation hole 42. Then the filter connection column 52 is separated from the sealing cover plate 46 to remove the filter mechanism 5 from the inside of the filter installation hole 42. When the filter mechanism 5 is installed, the filter mechanism 5 moves upward. When the filter mechanism 5 moves upward, the filter connection column 52 is inserted into the connection sleeve 48 The filter connection block 53 then enters the inclined section of the connection slot 49. When the filter 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 connection with the sealing slot 45. Then, the filter connection column 52 and the magnetic card block 410 attract each other to drive the sealing cover plate 46 to continue to rotate clockwise, and then continue to move the filter mechanism 5 upward until the filter limit ring 54 contacts the partition plate 41, and then through The fixing mechanism 6 fixes the position of the filter mechanism 5. When the filter mechanism 5 moves up and down inside the filter installation hole 42, the limit block 43 is engaged with the limit slide groove 55 to prevent the limit slide groove 55 from rotating during the up and down movement. When the filter mechanism 5 moves up and down, it can automatically drive the sealing cover plate 46 to connect and separate with the lower sealing ring 44 during installation and disassembly. When the sealing cover plate 46 is connected to the lower sealing ring 44, the filter installation hole 42 can be sealed to prevent unpurified sewage from flowing out of the filter installation hole 42.

[0053] Embodiment three:

[0054] See also Figure 6 - Fig.10 , which is different from the above-mentioned embodiment, is that the filter mechanism 5 comprises a filter housing 51, which is slidably mounted inside the filter mounting hole 42, a filter connecting column 52 is fixedly mounted on the top of the filter housing 51, a filter connecting block 53 is fixedly mounted on the outside of the filter connecting column 52, a filter limiting ring 54 is fixedly mounted on the outside of the filter housing 51, a limiting slide groove 55 is provided on the outside of the filter housing 51, a sewage partition plate 57 is fixedly mounted inside the filter housing 51, a sewage ultrafiltration pipe 56 is fixedly mounted inside the sewage partition plate 57, and a filter drain port 58 is provided at the bottom of the filter housing 51;

[0055] The outside of the filter housing 51 is slidably mounted inside the filter installation hole 42 through the limiting sliding groove 55 and the limiting block 43 inside the filter installation hole 42 .

[0056] The filter housing 51 is provided with a water inlet only in the upper half, and the sewage partition plate 57 can separate the upper half of the filter housing 51 provided with the water inlet and the closed lower half, the top of the sewage ultrafiltration tube 56 is fixedly connected to the top of the inside of 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 connected via a sewage ultrafiltration pipe 56 , which can deeply purify the wastewater as it passes through.

[0058] The outside of the filter connecting column 52 is connected to the connecting groove 49 on the filter limiting ring 54 through the filter connecting block 53. A notch is provided on the top of the filter connecting column 52. The suction force between the magnetic block 410 and the filter connecting column 52 can drive the sealing cover plate 46 to rotate on the filter connecting 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. A filter limit ring 62 is fixedly installed inside the limit handle 61. Spring connecting blocks 63 are fixedly installed on both sides of the limit handle 61. The spring connecting blocks 63 are connected to the partition plate 41 through the connecting spring 64.

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

[0062] During deep sewage purification, the sewage enters the interior of the filter housing 51 from the water inlet of the upper half of the filter housing 51. After the sewage enters the interior of the filter housing 51, the sewage ultrafiltration tube 56 can isolate the large molecular pollutants in the sewage outside the sewage ultrafiltration tube 56, and the relatively clean water flow passes through the sewage ultrafiltration tube 56 and the sewage partition plate 57 to enter 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 clamping of the filter limit ring 62 and the partition plate 41 to the filter limit ring 54. During the disassembly and assembly process, you only need to pull the limit handle 61 to drive the filter limit ring 62 to separate from the filter limit ring 54, thereby quickly completing the disassembly and replacement of the filter mechanism 5.
