Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane filtration technology, specifically to an ultrafiltration vibrating membrane separation device. Background Technology

[0002] Ultrafiltration technology, as a core branch of pressure-driven membrane separation technology, has been widely applied in various fields such as municipal wastewater treatment and reuse, advanced industrial wastewater treatment, and drinking water purification due to its core advantages of precise pore size, no phase change, relatively low energy consumption, and ability to retain pollutants such as colloids, macromolecular organic matter, and microorganisms. In industrial applications, flux decline caused by membrane fouling remains the core bottleneck restricting the efficient and stable operation of ultrafiltration technology. By incorporating a vibration component, the fouling layer on the membrane can be automatically removed.

[0003] Existing devices primarily use filter cartridges equipped with ultrafiltration membranes to filter wastewater. Many existing technologies resemble ultrafiltration membrane separation equipment. The structure of device CN220550026U includes a shell, a central tube inserted inside the shell, a base fixed to the bottom of the central tube, and a sliding fit between the base and the shell. A top pressure plate is slidably fitted onto the central tube, and this top pressure plate is also slidably fitted onto the shell. A filter element is movably fitted between the base and the top pressure plate. This device facilitates individual or complete replacement of the filter element and is relatively convenient to operate. However, there are still areas for improvement.

[0004] Existing devices mainly fix the filter cartridge on the support, making it difficult for some devices to drive the filter cartridge to vibrate at high frequency through the vibration separation mechanism. This makes it difficult to automatically clean the ultrafiltration membrane inside the filter cartridge, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an ultrafiltration vibration membrane separation device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an ultrafiltration vibration membrane separation device to solve the problem mentioned in the background art that the existing devices mainly fix the filter cartridge on the support, making it difficult for some devices to drive the filter cartridge to vibrate at high frequency through the vibration separation mechanism, thus making it inconvenient to automatically clean the ultrafiltration membrane in the filter cartridge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrafiltration vibrating membrane separation device, including a base support, a lifting frame provided directly above the base support, a filter cartridge fixedly mounted on the inner wall of the lifting frame, a transmission box fixedly mounted on the bottom left side of the top plate of the base support, a vibration separation mechanism provided inside the transmission box, a controller fixedly mounted on the front upper side of the transmission box, an inlet pipe fixedly connected to the bottom middle of the filter cartridge, a sewage pipe fixedly connected to the bottom right side of the filter cartridge, and a purified water pipe fixedly connected to the bottom left side of the filter cartridge.

[0007] Preferably, the filter cartridge has layers of ultrafiltration membranes stacked inside, and a fastening screw runs through the inner outer ring of the filter cartridge. The fastening screws are arranged in a ring array, and the inner outer ring of the ultrafiltration membrane has through holes corresponding to the fastening screws.

[0008] Preferably, the vibration separation mechanism includes a drive motor, the rear side of which is fixedly mounted below the front side of the transmission box, a drive shaft is fixedly connected to the middle of the rear side of the drive motor, the rear end of the drive shaft passes through the front side wall of the transmission box and is fixedly connected to a crankshaft, and the rear central shaft of the crankshaft is rotatably mounted on the rear side of the inner wall of the transmission box.

[0009] Preferably, a connecting rod is rotatably sleeved on the middle of the outer wall of the crankshaft, and a push-pull rod is movably connected to the top of the connecting rod. The top of the push-pull rod passes through the left top plate of the base bracket and is fixedly connected to the bottom left side of the lifting frame.

[0010] Preferably, a limiting rod is inserted into the bottom of the top plate of the base bracket, and the top end of the limiting rod passes through the top plate of the base bracket and is fixedly connected to the bottom of the lifting frame.

[0011] Preferably, a spring is fixedly connected to the top of the base bracket on the outer ring of the limiting rod, and the top end of the spring is fixedly connected to the bottom of the lifting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a movable connection between a base support and a lifting frame, allowing the lifting frame to drive the filter cartridge to vibrate up and down relative to the base support. This facilitates the addition of a vibration separation mechanism to the filter cartridge.
