Description

Technical Field

[0001] This utility model relates to the technical field of stacked ultrafiltration membrane devices, specifically a stacked self-rotating ultrafiltration membrane device. Background Technology

[0002] Stacked-plate ultrafiltration membrane devices are advanced membrane separation technology equipment. Their core components consist of multiple stacked membrane sheets, which typically have a double-sided grooved structure with different orientations, creating numerous intersections and cavities to intercept impurities in the water. The membrane sheets are usually made of high-quality engineering plastics with extremely high wear resistance. During use, impurities accumulate inside the stacked-plate ultrafiltration membrane device. When there are many impurities, cleaning is necessary. Cleaning is usually done through backwashing, but backwashing is not quick and thorough, and impurities can easily clog the membrane sheets during filtration, affecting filtration efficiency. Therefore, we propose a stacked-plate self-rotating ultrafiltration membrane device. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: a stacked self-rotating ultrafiltration membrane device, including a support, an ultrafiltration membrane assembly, a filter cartridge, a rotating assembly, a hose, a drain pipe, and a flow guiding assembly. The ultrafiltration membrane assembly includes a vertical pipe connected to the support bearing, a backwash pipe arranged on the outside of the vertical pipe, a first valve arranged on the vertical pipe, and a plurality of ultrafiltration membrane stacks arranged on the vertical pipe. The filter cartridge is fixed to the top of the support by screws. The rotating assembly includes a drive motor arranged at the bottom of the support, a first pulley arranged at the output end of the drive motor, and a second pulley connected to the first pulley by a belt and arranged on the outside of the vertical pipe. The hose is arranged on the backwash pipe, the drain pipe is arranged at the bottom of the support, and a second valve is arranged on the drain pipe. The flow guiding assembly is arranged on the support.

[0005] Preferably, the bracket has mounting holes for installing the flow guiding components, and gaskets are evenly distributed on both sides of the bracket.

[0006] Preferably, a baffle is provided on the outside of the vertical tube.

[0007] Preferably, the top of the filter cartridge is provided with a connecting pipe for connecting to the conveying pipeline, and the outer side of the filter cartridge is provided with a transparent plate.

[0010] Preferably, the flow guiding assembly includes a crossbar passing through the mounting hole, a flow guiding tube arranged on the left side of the crossbar, a stop block arranged on the flow guiding tube, and a nut threadedly connected to the crossbar.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up an ultrafiltration membrane assembly, filter cartridge, rotating assembly, hose, and drain pipe, achieves a self-rotating effect without affecting the use of the ultrafiltration membrane device, thus facilitating filtration and impurity removal. Simultaneously, by setting up a flow guiding assembly, liquid drainage is facilitated during rotation. In use, the user can connect one end of the hose to a tap water pipe and the other end to a backwash pipe. After connection, the first valve can be rotated to close, and then tap water can be transported through the vertical pipe to the ultrafiltration membrane stack for backwashing. The drive motor of the rotating assembly can then be controlled to operate. The motor drives the vertical tube and ultrafiltration membrane stack to rotate via the first and second pulleys. The rotating ultrafiltration membrane stack can quickly and thoroughly remove impurities through centrifugal force. The filtered impurities can be discharged through the drain pipe for use. During filtration, the rotating ultrafiltration membrane stack is not easily clogged by impurities, which greatly improves the filtration efficiency. At the same time, the crossbar of the flow guiding component can be inserted into the mounting hole of the bracket, and then the flow guiding tube can be inserted into the bottom of the vertical tube. By rotating the nut and fixing it to the crossbar, the flow guiding component can be fixed on the bracket.
