Description

Technical Field

[0001] The utility model relates to the technical field of membrane separation, in particular to a membrane separation device with multiple separation and filtering functions. Background Art

[0002] With the increasing demand for material separation and purification in modern industrial production and environmental protection, membrane separation technology has become an indispensable key technical means in many industries such as chemical, food, pharmaceutical, environmental water treatment, resource recycling, etc., due to its significant advantages such as high efficiency, energy saving, simple operation, and no phase change. However, in the face of complex and diverse systems to be separated, a single membrane component or a single filtration level of membrane separation equipment is often difficult to quickly separate substances of different particle sizes or molecular weights at one time. Therefore, a membrane separation equipment with multiple separation and filtration functions is needed to perform efficient and fast one-time separation and filtration of the liquid to be separated.

[0003] When the existing membrane separation equipment processes complex mixtures, the design of multiple separation and filtration functions can achieve fine separation of substances with different particle sizes or molecular weights, significantly improving the separation efficiency and purity. However, along with its high separation performance, there are high requirements for the maintenance and cleaning of the separation membrane. Especially when dealing with materials with high solid content, easy to scale or containing biologically active substances, the problem of membrane fouling is particularly prominent. Although the conventional backwash cleaning method can restore the membrane flux to a certain extent, its implementation process is complicated for multiple separation and filtration equipment, and often requires a large amount of water resources. In addition, the existing membrane separation equipment with multiple separation and filtration functions is often not convenient enough for the replacement of separation membranes in design. When the membrane is severely contaminated or the performance is degraded due to long-term use, due to the complex installation structure of the equipment itself, the replacement process of the separation membrane requires complex disassembly and assembly steps, which is time-consuming and labor-intensive, affecting the efficiency of the overall operation. For the problems in the related art, no effective solution has been proposed yet. Therefore, it is necessary to propose a membrane separation device with multiple separation and filtration functions to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, in order to achieve a sliding connection between the telescopic rod and the end of the transmission motor, a sliding block is fixedly connected to the end of the telescopic rod, and a sliding groove is opened at the end of the transmission shaft of the transmission motor. The sliding block cooperates with the sliding groove.

[0010] Furthermore, in order to realize the detachable installation of the sealing cover, a sealing ring is fixedly connected to one end of the coarse filter cartridge, the fine filter cartridge and the ultrafiltration cartridge, and a sealing groove is opened at one end of the sealing cover.
