Description

Technical Field

[0001] The utility model relates to the technical field of water purification devices, in particular to a non-aerated immersed ultrafiltration membrane structure. Background Art

[0002] Ultrafiltration membranes are widely used in the water treatment industry and can effectively remove impurities such as suspended solids, colloids, microorganisms, and macromolecular organic matter in water. However, as impurities gradually accumulate on the membrane surface, they will cause contamination and clogging of the membrane; therefore, the ultrafiltration membrane needs to be cleaned to extend its service life.

[0003] When submerged ultrafiltration membrane is used to treat drinking water, in order to make pollutants fall off the surface of membrane fibers, a high-pressure fan is usually set to blow air into the membrane pool to enhance the turbulence of the pool water and the shaking of the membrane fibers. Sometimes, due to insufficient or uneven air distribution, pollutants cannot fall off the surface of the membrane fibers smoothly, resulting in poor cleaning effect, thereby reducing the water output of the membrane system. In addition, due to the high power of the fan and high operating costs, the fan electricity cost accounts for more than half of the total operating cost.

[0004] Therefore, it is necessary to propose a non-aerated immersed ultrafiltration membrane structure to improve the cleaning effect of the ultrafiltration membrane while saving equipment costs and operating expenses. Summary of the invention

Under the elastic force of the elastic seat, the vibration amplitude of the installation frame increases, and the installation frame transmits the vibration to the ultrafiltration membrane curtain assembly.

[0025] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1-Figure 2 The utility model proposes an aeration-free immersed ultrafiltration membrane structure, including an elastic seat 1, a mounting frame 2, a vibration motor 3, and a plurality of ultrafiltration membrane curtain assemblies 4.

[0027] In this embodiment, the utility model needs to be placed in a membrane pool for filtration, and the membrane pool is used to store water source water. When filtering the water source water, the pumping pipe absorbs water from the ultrafiltration membrane curtain assembly 4, and the ultrafiltration membrane curtain assembly 4 absorbs the raw water in the membrane pool. After the raw water is filtered, it flows from the inside of the ultrafiltration membrane curtain assembly 4 to the pumping pipe, and the pollutants will adhere to the surface of the ultrafiltration membrane curtain assembly 4. During the cleaning process, the vibration motor 3 is used to transmit high-frequency vibration to the installation frame 2. Under the elastic force of the elastic seat 1, the vibration amplitude of the installation frame 2 increases, and then the installation frame 2 transmits the vibration to the ultrafiltration membrane curtain assembly 4. On the membrane curtain assembly 4, since one end of the ultrafiltration membrane curtain assembly 4 is elastically connected to the inner side of the mounting frame 2, the vibration amplitude increases again at this time, and the mounting frame 2 drives the ultrafiltration membrane curtain assembly 4 and the pool water to vibrate at a high frequency, producing a principle similar to ultrasonic cleaning of objects, so that pollutants are quickly removed from the surface of the ultrafiltration membrane or pollutants are difficult to approach the surface of the ultrafiltration membrane. Compared with the method of the blower in the prior art blowing air at the bottom of the ultrafiltration membrane to remove pollutants from the surface of the ultrafiltration membrane and cleaning by driving water turbulence with bubbles, the utility model adopts vibration to better realize the cleaning function and improve the cleaning effect;

[0028] In summary, the aeration-free immersed ultrafiltration membrane structure improves the cleaning effect of the ultrafiltration membrane and saves equipment cost and operation cost at the same time.

[0029] In this embodiment, an elastic connecting frame 21 is provided in the mounting frame 2, one end of the elastic connecting frame 21 is elastically connected to an inner side of the mounting frame 2, and one end of a plurality of ultrafiltration membrane curtain assemblies 4 is fixedly connected to the other end of the elastic connecting frame 21; in order to increase the swing amplitude of the ultrafiltration membrane curtain assembly 4 during vibration, the elastic connecting frame 21 is provided inside the mounting frame 2, that is, when the mounting frame 2 vibrates, the vibration is transmitted to the ultrafiltration membrane curtain assembly 4 through the elastic connecting frame 21, and the ultrafiltration membrane curtain assembly 4 generates non-directional swinging vibration, and during the continuous vibration process, under the elastic action of the elastic connecting frame 21, the vibration direction of the mounting frame 2 will also be staggered with the vibration direction of the ultrafiltration membrane curtain assembly 4, thereby increasing the amplitude of the vibration, and the vibration causes the impact force of the water to clean the ultrafiltration membrane curtain assembly 4.

[0031] In this embodiment, a fixing rod group 22 is provided in the installation frame 2, and one end of the fixing rod group 22 is fixedly connected to an inner side of the installation frame 2.

When vibrating cleaning is performed, high-frequency swinging vibration will be performed with the connection between the second connecting rod 221 and the ultrafiltration membrane curtain assembly 4 as the origin of the angle swing.

In this way, there is enough space between the ultrafiltration membrane curtain assemblies 4 to guide the detached pollutants to flow out of the membrane pool space, so that the pollutants are precipitated at the bottom of the membrane pool, and the membrane pool will also regularly discharge the precipitated pollutants through the sewage pipe to ensure that the pollutant concentration in the membrane pool is maintained at a low level.

[0033] In this embodiment, the ultrafiltration membrane curtain assembly 4 includes a fixed pipe rack 41 and a plurality of ultrafiltration membrane filaments 42. The plurality of ultrafiltration membrane filaments 42 are arranged in sequence and fixedly connected to the fixed pipe rack 41, and the plurality of ultrafiltration membrane filaments 42 are all connected to the fixed pipe rack 41. The fixed pipe rack 41 is a hollow structure, which is connected to an external water pumping pipe.
