[0021] The diaphragm 14 is placed in the middle of the guide plate 13, and a sealing rubber ring is added at the connection between the diaphragm 14 and the guide plate 13 to increase the sealing of the connection to a certain extent. The diaphragm 14 and the guide plate 13 are stacked and assembled at intervals, and the inlet and outlet water flows through the "S"-shaped gap between the diaphragm 14 and the guide plate 13. The diaphragm 14 is embedded in the middle of the slot 15 opened in the membrane column 5 through the insert 16, and then a hydraulic suction cup clamp 17 is used to form a clamping and fixing structure for the diaphragm 14 to ensure the stability and position accuracy of the diaphragm during the installation process. The hydraulic suction cup clamp 17 can be adjusted according to different sizes and shapes of the diaphragm 14, so as to achieve adaptability to the installation of the diaphragm 14, improve the installation efficiency of the diaphragm 14, and enhance the ease of maintenance.

[0022] Furthermore, the upper end of the membrane shell 1 is fittedly connected with an upper end cover 2, and the upper end cover 2 is penetrated by a screw 3, and the two ends of the screw 3 are threadedly connected with a first nut 4, and the bottom end of the membrane shell 1 and the screw 3 are penetrated by a lower end cover 10. The upper end cover 2 and the lower end cover 10 are located at the upper and lower ends of the membrane column 5, together with the membrane shell 1, the diaphragm 14, the guide plate 13 and other components, through the screw 3 to penetrate the two end covers, and are fixed by the first nut 4 to form a complete membrane column structure.

[0023] Furthermore, threaded coils 6 are provided at the upper and lower ends of the membrane column 5, and washers 7 are fitted and connected at the upper and lower ends of the membrane column 5 and at the connection points with the upper end cover 2 and the lower end cover 10. The upper and lower ends of the membrane column 5 are threadedly connected with a second nut 8, and washers 7 are added at the connection points between the upper end cover 2 and the lower end cover 10 and the membrane column 5.

[0024] Furthermore, a feed port 9 is fixedly connected to the upper end surface of the upper end cover 2, and the other end of the feed port 9 passes through the middle of the guide plate 13. A permeate outlet 11 is fixedly installed at the bottom end of the membrane column 5. The permeate outlet 11 is added to the bottom of the membrane column 5 to allow the permeate after filtration, purification and desalination by the membrane assembly to flow out of the membrane assembly, thereby completing the entire filtration and purification process.

[0025] Furthermore, a sealing disk 12 is connected to the lower end surface of the upper end cover 2, the inner end surface of the lower end cover 10 and the guide disk 13.

[0026] Working principle: For this type of DTRO membrane column diaphragm installation and connection device, the diaphragm 14 is placed in the middle of the guide plate 13, and a sealing rubber ring is added at the connection between the diaphragm 14 and the guide plate 13. The diaphragm 14 and the guide plate 13 are stacked and assembled at intervals. The inlet and outlet water flows through the "S"-shaped gap between the diaphragm 14 and the guide plate 13. The diaphragm 14 and the membrane column 5 are installed through a hydraulic suction cup clamp 17 to form an upper and lower clamping and fixing structure for the diaphragm 14, so as to ensure the stability and position accuracy of the diaphragm during the installation process. Then, the sealing plate 12 is covered on the outer surface of the guide plate 13 at both ends, and then the upper end cover 2 and the lower end cover 10 are covered on the sealing plate. 12 upper and lower ends are fastened together by screw 3 to form a complete membrane column structure, and finally the pretreated water flow enters the membrane assembly through the feed port 9. When the incoming water enters the membrane assembly, the centrifugal force generated by the "S"-shaped structure will cause the suspended matter and sediment in the incoming water to be thrown off and deposited on the inside and outside of the membrane to form a filter press layer. The incoming water enters the internal flow channel of the membrane assembly through the membrane pores inside the diaphragm 14. These membrane pores only allow water and dissolved substances to pass through, while most of the solute and solvent molecules are retained, thereby realizing the separation and purification of water. The pure water passing through the membrane assembly is discharged through the water outlet and becomes a clear water source that can be directly used.
