Description

Technical Field

[0001] This utility model relates to the field of membrane filtration technology, and in particular to a membrane filtration concentration device. Background Technology

[0002] A membrane filtration concentration device is a device that uses membrane separation technology to filter and concentrate liquids. Membrane filtration technology uses high-precision membrane materials with selective separation function. According to the mechanical sieving principle, the separation and concentration of different components in the liquid are achieved through the precise matching of the filter element and the material system. When the equipment is running, the material is pressurized by the circulation pump, and the liquid flows along the surface of the filter membrane at a certain flow rate. Substances with a molecular weight greater than the membrane cutoff do not pass through the membrane and flow back to the circulation tank, while substances or molecules with a molecular weight less than the membrane cutoff pass through the membrane to form filtrate.

[0003] Patent document CN218188953U discloses a membrane filtration concentration device, relating to the field of membrane filtration concentration technology. The device includes a base, a support mounted on one side of the top of the base, a filter barrel mounted on the top of the support, a filter membrane installed inside the filter barrel, a motor mounted at the center of the top of the filter barrel, and a rotating shaft connected to the output end of the motor. One end of the rotating shaft passes through the interior of the filter barrel, and the rotating shaft is located at the center of the filter membrane. The bottom end of the rotating shaft is rotatably connected to the filter membrane. Connecting frames are fitted on both ends of the rotating shaft located inside the filter membrane. Two guide plates are connected between the two connecting frames, and the two guide plates are located at opposite ends of the connecting frames. This device can guide the concentrated liquid near the surface of the filter membrane to the center and maintain a relatively uniform liquid concentration inside the filter membrane through stirring blades, thereby making it easier for subsequent liquids to pass through and improving filtration efficiency.

[0004] While the aforementioned application improves the filtration effect during use, pressure variations can lead to different filtration results in actual applications. Therefore, when filtering different liquids, the filtration pressure needs to be adjusted according to their characteristics. If the pressure cannot be adjusted, it will affect the normal filtration operation of the device. Utility Model Content
