[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 2-Figure 3 As shown, the utility model provides a special cleaning device for ultrafiltration, comprising: a device body 1, a clean water tank 2 is provided on the top of the device body 1, two installation tanks 3 are provided on the top of the device body 1, a fixed tank 4 is provided on the top of the device body 1, an ultrafiltration membrane 5 is movably inserted in the inner surface wall of the fixed tank 4, a cleaning mechanism 6 is provided on the inner surface walls of the two installation tanks 3, and a sewage tank 7 is provided on the bottom of the inner wall of the two installation tanks 3;

[0023] The cleaning mechanism 6 includes two water pumps 601, the output ends of the two water pumps 601 are fixedly connected to water pipes 602, and one end of the outer wall of the two water pipes 602 is fixedly connected to the two ends of the outer wall of the ultrafiltration membrane 5 respectively, the input ends of the two water pumps 601 are fixedly connected to valves A603 through pipelines, and the input ends of the two valves A603 are fixedly connected to water inlet pipes 604.

[0024] The effect achieved by the entire embodiment 1 is that by setting two identical cleaning mechanisms 6, the ultrafiltration membrane 5 is stuck inside the fixed groove 4, and then the two ends of the ultrafiltration membrane 5 are respectively connected to one end of the two water pipes 602. In this way, when the ultrafiltration membrane 5 needs to be flushed forward, it is only necessary to start the water pump 601 connected to one end of the water inlet of the ultrafiltration membrane 5 to transport clean water into the ultrafiltration membrane 5, and then the sewage will flow out through the bottom of the other water pipe 602, and finally flow into the corresponding sewage tank 7. When reverse flushing is required, start the other water pump 601, and clean water will enter through the sewage outlet of the ultrafiltration membrane 5 to flush out the impurities inside the ultrafiltration membrane 5 from the water inlet, thereby improving the efficiency of cleaning the ultrafiltration membrane 5.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the bottom ends of the two water pipes 602 are fixedly connected with valves B605, the output ends of the two valves B605 are fixedly connected with hoses 606, and the output ends of the two hoses 606 are respectively connected to the interiors of the two sewage tanks 7, a water quality sensor 8 is provided on one side of the inner wall of the two sewage tanks 7, and one side of the outer wall of the two sewage tanks 7 and the clean water tank 2 are fixedly connected with a drain port 9 through a valve, a top cover 10 is movably installed on the top of the device body 1, two clamping blocks 11 are fixedly installed on the bottom of the top cover 10, and the two clamping blocks 11 are respectively movably inserted in the inner surface walls of the two fixed grooves 4, a handle 12 is welded on the top of the top cover 10, and a rubber sleeve 13 is welded on the top of the handle 12.

[0026] The effect achieved by the entire embodiment 2 is that, by setting the valve B605 and the hose 606, it is connected with the sewage tank 7, so that the sewage can be directly discharged into the sewage tank 7 to prevent it from being discharged into the installation tank 3 to pollute the device body 1. At the same time, the sewage discharged into the sewage tank 7 will also be monitored by the water quality sensor 8 at any time to confirm whether the flushing is completed. During the flushing process, the top cover 10 and the block 11 can fix the ultrafiltration membrane 5 in the fixed tank 4 to prevent the ultrafiltration membrane 5 from shifting due to shaking, thereby improving the stability of the entire device.

[0027] The working principle of the whole device is as follows: first, connect the two water inlet pipes 604 to the container storing the water source, and at the same time, install the ultrafiltration membrane 5 in the fixed groove 4, and connect the two ends of the ultrafiltration membrane 5 to the output ends of the two water pipes 602 respectively, and then cover the top cover 10, and let the block 11 be stuck in the installation groove 3 to prevent the ultrafiltration membrane 5 from shaking. Here, it is assumed that the left side of the ultrafiltration membrane 5 is the water inlet and the right side is the sewage outlet. When the ultrafiltration membrane 5 needs to be forward flushed, open the valve B605 on the right, start the water pump 601 on the left, and let the clean water on one side of the container enter the interior of the ultrafiltration membrane 5 through the water inlet pipe 604, the water pump 601, the water pipe 602 and the water inlet of the ultrafiltration membrane 5, and a part of the clean water will flow into the clean water tank 2 through the outlet of the ultrafiltration membrane 5, and then pass through The drain outlet 9 of the clean water tank 2 is discharged outside the device for recycling, thereby achieving an environmental protection effect. In addition, muddy water containing impurities will be discharged into the water pipe 602 on the right through the drain outlet, and discharged into the sewage tank 7 on the right through the bottom end of the water pipe 602 on the right, valve B605 and hose 606, and then discharged outside the device for recycling through the drain outlet 9 in the sewage tank 7. Then the sewage accumulated in the sewage tank 7 will be continuously detected by the water quality sensor 8. When it is detected that the water quality meets the requirements, it means that the flushing is completed. When reverse flushing is required, it is only necessary to follow the above-mentioned steps in the opposite direction to allow clean water to enter through the drain outlet of the ultrafiltration membrane 5 to achieve reverse flushing. When both the forward flushing and the reverse flushing are completed, the rubber sleeve 13 on the handle 12 can be held to remove the top cover 10, and then the ultrafiltration membrane 5 can be removed.

[0028] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
