Description

Technical Field

[0001] The utility model relates to the technical field of degassing membranes, and more specifically to a degassing membrane hydrophobic treatment device. Background Art

[0002] A large number of hollow fibers are installed in the degassing membrane. There are tiny holes on the walls of the fibers. Water molecules cannot pass through such small holes, while gas molecules can pass through. During operation, water flows through the inside of the hollow fibers under a certain pressure, and the gas outside the hollow fibers is continuously pumped away under the action of a vacuum pump, forming a certain negative pressure. In this way, the gas in the water continuously overflows from the water through the hollow fibers, so as to achieve the purpose of removing the gas in the water. Installing a large number of hollow fibers in the degassing membrane can expand the area of the gas-liquid interface, thus accelerating the degassing speed.

[0003] The degassing membrane can perform gas-liquid separation. When the existing degassing membrane is in use, pipelines are installed at its liquid inlet end, liquid outlet end and air extraction end. Generally, they are connected to the pipelines through flanges. However, the positions of the flanges are fixed. When the connection holes of the two flanges are not aligned, it is inconvenient to connect the two flanges at this time, resulting in inconvenient disassembly and assembly.

The surface of the T-shaped insertion rod abuts against the inner wall of the positioning hole. A threaded hole is formed in the side surface of the installation box. A screw rod is threadedly connected to the inner wall of the threaded hole. The end surface of the screw rod abuts against the side surface of the T-shaped insertion rod. A rotating block is fixedly connected to the end of the screw rod away from the T-shaped insertion rod.

[0007] Further, an arc-shaped mounting plate is installed on the surface of the degassing membrane body. The inner ring surface of the arc-shaped mounting plate abuts against the surface of the degassing membrane body. A fixing plate is fixedly connected to the back surface of the arc-shaped mounting plate. Mounting holes are formed in the back surface of the fixing plate.

The upper surface and the lower surface of the T-shaped positioning block are both arc-shaped. A plurality of positioning grooves adapted to the T-shaped positioning block are formed in the surface of the degassing membrane body. The surface of the T-shaped positioning block abuts against the inner wall of the positioning groove. The number of the T-shaped positioning blocks is two, and the two T-shaped positioning blocks are symmetrically arranged on the inner ring surface of the arc-shaped mounting plate.
