Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and in particular relates to an automatic cleaning device for domestic sewage membrane. Background Art

[0002] Sewage membrane technology has been widely used as an efficient and environmentally friendly sewage treatment method. When the sewage membrane filters sewage, various dirt and impurities are easily accumulated, resulting in clogging of the membrane pores and degradation of performance, which seriously affects the efficiency and quality of sewage treatment. It is necessary to use an automatic sewage membrane cleaning device to clean the sewage membrane.

[0003] In the prior art, an automatic cleaning device is provided at the bottom of the MBR membrane pool. Although such a design can be used for cleaning, the cleaning speed of membrane pollution is slow and the cleaning is not thorough. After a period of time, the system needs to be stopped to perform drug washing on a separate MBR membrane assembly. When the MBR membrane is cleaned separately, the sludge and viscous substances on the MBR membrane must first be cleaned, and then the membrane must be soaked in drugs before it can be cleaned. When cleaning the sludge and viscous substances on the MBR membrane, it is necessary to rinse it with clean water. Due to the high density of the MBR membrane, some sludge and viscous substances are sandwiched between the membranes, and the MBR membrane needs to be manually shaken to clean the sludge and viscous substances, which consumes a lot of manpower and material resources.

[0004] The existing patent (application number: CN215782756U) is a domestic sewage MBR membrane automatic cleaning device. The first swing rod swings to drive the two cleaning parts at both ends to move up and down in turn, which can fully clean both sides of the MBR membrane and increase the cleaning area. The first swing rod can also reduce the driving power source. The clamp is hinged on the body and can also drive the MBR membrane to rotate. Impurities on the MBR membrane can be removed by shaking, achieving double-layer cleaning and better cleaning effect.

[0005] In view of the above problems, existing patents have provided solutions. However, in actual use, the cleaning of the sewage membrane by the cleaning parts may increase the risk of damage to the membrane material. If not properly controlled, it may damage the microstructure of the sewage membrane and may cause the membrane pores to deform, expand or even rupture, thereby affecting the filtration performance and service life of the membrane. Improvements are needed. For this purpose, an automatic cleaning device for domestic sewage membrane is proposed. Utility Model Content

[0031] Working principle:

[0032] 1. In the initial state of the device, the sewage membrane 2 and the frame 3 outside it are in the position to be installed. The operator places the frame 3 and the sewage membrane 2 as a whole on the horizontal plate 7 stably, ensuring that the frame rod in the middle of the bottom surface of the frame 3 is accurately slid into the limit opening 8 of the horizontal plate 7. This step ensures that the sewage membrane 2 and the frame 3 are stably aligned in the device;

[0033] Subsequently, the operator drives the driving members 11 on both sides, that is, turns the handle 113, so that the screw rod 112 on the connecting plate 111 rotates. The screw rod 112 and the clamping plate 9 are threadedly connected, so the rotation of the screw rod 112 drives the clamping plate 9 to move horizontally on the crossbar 6. When the connecting port 10 on the side of the clamping plate 9 is completely inserted into the frame rod at the bottom of the frame 3, the clamping plates 9 on both sides clamp and fix the frame 3 and the sewage membrane 2. This clamping method is not only stable, but also can adapt to sewage membranes 2 and frames 3 of different sizes.

[0034] 2. After the fixation is completed, the operator starts the rotating mechanism 12, and the motor 121 is used as the power source. Its output shaft drives the driving wheel 122 to rotate. The driving wheel 122 is connected to the driven wheel 123 through the belt 124, so the driven wheel 123 also rotates. The driven wheel 123 is fixedly installed in the middle of the bottom surface of the turntable 4, so the rotation of the turntable 4 will drive the frame 3 and the sewage membrane 2 fixed thereon to rotate together.

[0035] At the same time, the spraying mechanism 13 starts to work, the electric spray disc 134 is connected to the external water source through the water pipe 135, and after starting, it sprays water to directly flush the rotating sewage membrane 2, and the electric slide 132 drives the electric slider 133 to slide on the slide, thereby realizing the height adjustment of the electric spray disc 134. This function enables the device to flush different parts of the sewage membrane 2, ensuring the comprehensiveness and uniformity of the cleaning effect;

[0036] 3. During the rotation of the sewage membrane 2, due to the action of centrifugal force, the dirt attached to the surface of the membrane is subjected to an outward force, making it easier to separate from the membrane body. At the same time, the impact force of the water flow sprayed by the spraying mechanism 13 is combined with the centrifugal force to more effectively remove stubborn dirt. This combined cleaning method not only improves the cleaning efficiency, but also avoids the damage to the membrane body that may be caused by traditional mechanical cleaning.

[0037] 4. During the entire cleaning process, the operator can automatically control the various components of the device through the controller. The controller is electrically connected to the motor 121, the electric slide 132, the electric slider 133, the electric spray disc 134 and other components, which can realize automatic control of the entire cleaning process, which not only improves the convenience of operation, but also reduces the error and labor intensity of manual operation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
