Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration membranes, in particular to an external pressure type ultrafiltration membrane water filtration component. Background Art

[0002] Ultrafiltration membrane is a microporous filtration membrane with consistent pore size specifications and a rated pore size range of less than 0.01 microns. By applying appropriate pressure on one side of the membrane, solute molecules smaller than the pore size can be screened out to separate particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers. Ultrafiltration membrane is one of the earliest developed polymer separation membranes. Ultrafiltration devices were industrialized in the 1960s. Ultrafiltration membrane water purification is divided into two methods: external pressure and internal pressure. When the external pressure ultrafiltration membrane purifies water, the raw liquid penetrates from the outer wall of the membrane fiber to the inner wall of the membrane fiber. The pollutants exist between the outer walls of each membrane fiber tube. Due to the obstruction of the membrane shell, the pollutants cannot be completely carried away by the direct current of clean water. Over time, the ultrafiltration membrane is blocked.

[0003] After searching, the Chinese patent application No. 202322912551.2 discloses an external pressure ultrafiltration membrane element, which includes an external pressure tube shell and a filter membrane fiber arranged in the external pressure tube shell, an annular tube located outside the filter membrane fiber is rotatably arranged in the external pressure tube shell, the inner wall of the annular tube is connected to a plurality of nozzles, a rotating assembly driving the annular tube to rotate is arranged on the external pressure tube shell, and a water inlet connected to the annular tube is fixed at the top of the external pressure tube shell;

[0004] Although the above patent can perform rotational spraying on the filter membrane fibers through the nozzle, thereby facilitating multi-angle flushing of the filter membrane fibers, facilitating sufficient cleaning of the filter membrane fibers, facilitating the use of the ultrafiltration membrane, and improving the filtration effect of the ultrafiltration membrane, there are still the following deficiencies during use: 1. When cleaning the filter membrane, it is necessary to connect the water inlet to the external water source separately, and the cleaning process is relatively complicated, which is not convenient for synchronous cleaning of the filter membrane during use; 2. When installing the external pressure tube shell, it is not convenient to flexibly adjust to match the installation requirements of different scenarios, resulting in poor practicality.

[0005] Therefore, an external pressure ultrafiltration membrane water filtration component is urgently needed to solve the above problems. Summary of the invention

[0027] like Figure 1-6 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the automatic sewage discharge component includes a dredging groove 120 opened on the bottom wall of the tube shell 100, and the dredging groove 120 is evenly distributed in two to five groups along the bottom wall of the tube shell 100. The bottom wall of the tube shell 100 is rotatably connected with a baffle 121, and the inner wall of the baffle 121 is provided with a guide groove 122 for cooperating with the dredging groove 120. The push plate 112 cooperates with the dredging groove 120 and the guide groove 122. Through the action of the baffle 121, the tube shell 100 can be easily closed and opened according to the needs of use, and the practicality is stronger.
