[0027] The driven shaft 7 is rotatably arranged on the top surface of the end plate 41, and the bottom end of the driven shaft 7 is fixedly connected with a driven fan gear 71 that can mesh with the driving fan gear 62. When the driving fan gear 62 meshes with the driven fan gear 71 and the driving shaft 6 rotates, the driven shaft 7 can be driven to rotate.

[0028] The transmission shaft 8 is rotatably arranged on the top surface of the end plate 41. The transmission shaft 8 passes through the threaded seat 72 to prevent the threaded seat 72 from rotating.

[0029] See also Figure 1 to Figure 6 Preferably, a plurality of guide rail seats 13 are fixedly connected to the side wall of the base 1, one end of each guide rail seat 13 is provided with an opening, the guide rail seats 13 are connected to the closing plate 32 in a one-to-one correspondence, and the inner side walls of the guide rail seats 13 are provided with sealing strips that can cooperate with the closing plate 32, which can improve the sealing effect.

[0030] See also Figure 1 to Figure 6 Preferably, a matching groove is provided on the side wall of the base 1 at one end of the opening of the guide rail seat 13, an auxiliary plate 33 is provided on the side of the closing plate 32 close to the outer tube 2, a plurality of pins passing through the auxiliary plate 33 are fixedly connected to the side wall of the closing plate 32, and a plurality of second springs are provided between adjacent auxiliary plates 33 and the closing plate 32. When the plurality of second springs are in a natural state, the auxiliary plate 33 cooperates with the matching groove, and a sealing strip that cooperates with the closing plate 32 is fixedly connected to the auxiliary plate 33, which can further improve the sealing effect.

[0031] See also Figure 1 to Figure 6 Preferably, the bottom end of the inner tube 22 is connected to a base 5, the base 5 is fixedly connected to the bottom surface of the base 1, a plurality of flow ports are opened on the side wall of the base 5, and a plurality of baffles 34 are fixedly connected to the bottom surface of the turntable 3 located below, and the baffles 34 correspond to the flow ports one by one.

[0032] See also Figure 1 to Figure 6 Preferably, when the device is in use, the base 1 is immersed in a domestic wastewater pool, so the driving member 61 should be waterproofed.

[0033] See also Figure 1 to Figure 6 Preferably, the driving member 61 is a rotating motor that can provide sufficient power.

[0034] See also Figure 1 to Figure 6 Preferably, the user can add a plurality of air ducts on the outer surface of the base 1, and the air ducts are all fixedly connected to the base 1. The air ducts are all connected to a blower, and the blower can blow air into the domestic wastewater pool, thereby driving the domestic wastewater to flow and preventing impurities from being deposited at the bottom of the domestic wastewater pool.

[0035] During the implementation of the present invention: during the use of the device, the closing plate 32 does not cooperate with the through-hole 12, and the shielding plate 34 cooperates with the flow port. At this time, the suction pump at the extension pipe 21 connected to the clean water tank is started, and the domestic wastewater flows from the domestic wastewater tank to the outer pipe 2. The water filter membrane 4 filters the domestic wastewater passing through it, and the impurities filtered out are attached to the outer wall of the water filter membrane 4. When there are too many impurities attached to the water filter membrane 4, the above-mentioned suction pump is turned off, and the driving member 61 is started. The driving member 61 rotates forward, driving the driving shaft 6 to rotate clockwise, and under the meshing action of the transmission gear 83 and the arc rack 9, the turntable 3 is driven to rotate a certain angle, so that the closing plate 3 2 cooperates with the through-opening 12 (adjusting the connection mode between the arc rack 9 and the turntable 3 so that the arc rack 9 can drive the turntable 3 to rotate. This is a prior art and will not be described in detail). In this process, since the active fan gear 62 and the driven fan gear 71 are in meshing state, the active shaft 6 drives the driven shaft 7 to rotate, so that the threaded seat 72 rises along the driven shaft 7 until the locking sleeve 73 abuts against the side wall of the connecting plate 31 to achieve the locking of the connecting plate 31. At this time, the active fan gear 62 is disengaged from the driven fan gear 71, and the lifting sleeve 64 lifts the lifting gear 63, so that the lifting gear 63 is disengaged from the arc rack 9 (during this period, the closing plate 32 is firstly engaged with the through-opening 12 cooperates, at this time, the active fan gear 62 is still meshed with the driven fan gear 71, the lifting gear 63 is still meshed with the arc rack 9, the active shaft 6 continues to rotate clockwise, the guide rail seat 13 limits the closing plate 32, so that the turntable 3 cannot continue to rotate, the first spring is compressed), and then the driving member 61 continues to drive the active shaft 6 to rotate clockwise. Since the active fan gear 62 is not meshed with the driven fan gear 71, the lifting gear 63 is not meshed with the arc rack 9, and the active fan gear 62 can be meshed with the inner gear ring, the active shaft 6 only drives the turntable 3 to rotate, so that the spiral brush 44 cleans the surface of the water filter membrane 4. At the same time, the extension of the cleaning liquid chamber is connected The suction pump at the tube 21 is started, so that the cleaning liquid passes through the outer tube 2 and rushes to the water filter membrane 4 (the cleaning liquid is generally cleaning water containing sodium hypochlorite or hydrogen peroxide as the first oxidant, which is a prior art and will not be described in detail). The cleaning liquid backwashes and soaks the water filter membrane 4 (the user can also add a suction pump at the inner tube 22 to drain the domestic wastewater in the base 1 before backwashing and soaking the water filter membrane 4 to improve the cleaning effect). After soaking for a certain period of time, the suction pump at the extension tube 21 connected to the clean water tank is started to pump water into the outer tube 2 to flush the water filter membrane 4, and the flushed impurities and domestic wastewater are discharged into the impurity tank through the inner tube 22.Then the driving member 61 drives the active shaft 6 to rotate counterclockwise, and under the cooperation of the fixed lever 45 and the one-way lever 82, drives the transmission shaft 8 to rotate. At this time, the transmission gear 83 and the driven fan gear 71 are in a meshing state (when the active shaft 6 rotates clockwise, the fixed lever 45 and the one-way lever 82 cooperate to make the one-way lever 82 rotate with its connection point with the mounting seat 81 as the center of the circle, and cannot drive the transmission shaft 8 to rotate). The transmission gear 83 drives the driven fan gear 71 to rotate until the driven fan gear 71 is meshed with the active fan gear 62, and the active fan gear 62 continues to rotate counterclockwise, driving the threaded seat 72 to descend, the locking sleeve 73 is disengaged from the connecting plate 31, the lifting gear 63 is meshed with the arc rack 9, and drives the extension tube 21 to reset.

[0036] The user can control the rotation direction and start-up time of the driving member 61 through PLC, and can also add a water quality detector inside the outer tube 2 and the inner tube 22 to determine the water filtering effect. These are all existing technologies and will not be described in detail in the present invention.

[0037] The present invention provides an immersion type ultrafiltration water purification device, which has the following beneficial effects: 1. By setting up structures such as filter membranes and closing plates, it is possible to not only perform ultrafiltration purification on domestic wastewater, but also clean the surface of the filter membrane, thereby extending the working time of the filter membrane. Moreover, there is no need to dismantle the structure when cleaning the filter membrane, thus ensuring good operating efficiency.

[0038] 2. By setting up structures such as inner pipes and outer pipes, the diversion of purified water and clean water can be achieved, and impurities can be prevented from flowing back into the domestic wastewater pool during cleaning, ensuring a good domestic wastewater filtration effect.

[0039] 3. By setting up spiral brushes, inner tubes and outer tubes and other structures, the water filter membrane can be soaked and backwashed, which improves the cleaning effect of the water filter membrane and extends its service life and continuous operation time.

[0040] In summary, the beneficial effects of the present invention are: it can not only perform self-cleaning by combining immersion and backwashing on the water filter membrane without disassembling the device, but also prevent impurities from flowing back into the domestic wastewater pool, thereby extending the service life and continuous operation time of the device and ensuring good operating efficiency and filtering effect.
