Description

Technical Field

[0001] The utility model mainly relates to the technical field of nanofiltration membrane components, in particular to a nanofiltration membrane component for treating salt lake brine. Background Art

[0002] Membrane separation technology has been matured year by year, and it has been widely used in various fields. Nanofiltration is a new membrane separation technology between reverse osmosis and ultrafiltration. It is a new type of pressure-driven membrane process developed to meet the needs of industrial softening water and reduce costs. Nanofiltration membranes are mainly used for the concentration and purification of macromolecular substances in solutions. Nanofiltration membrane separation water treatment systems have unique structures and properties.

A sewage treatment chamber is provided in the component housing, two buffer blocks are symmetrically fixed in the sewage treatment chamber, a buffer chamber is provided in the buffer block, two water holes are symmetrically provided on both sides of the buffer chamber, a buffer slider is slidably provided in the buffer chamber, the buffer slider is connected to the buffer chamber by a reset spring, an electromagnet is fixedly provided in the buffer block, and the position of the electromagnet corresponds to that of the buffer slider. The utility model adopts the design of the component housing, the buffer block, the nanofiltration membrane cylinder and the buffer slider. After the nanofiltration membrane component is powered on, the electromagnet is powered on to absorb the buffer slider to move, and after the electromagnet is powered off, the buffer slider is slowly reset by the reset spring, so that the water flow and pressure passing through the filter core tube can be gradually increased.

[0004] However, the above scheme still has shortcomings when used. The above scheme cannot set anti-detachment measures for the interface of the nanofiltration membrane component. After the water flow and pressure increase, the water pipe at the interface is easy to fall off under the action of the reverse thrust, resulting in the nanofiltration membrane component cannot be used normally and cause losses.

[0005] Therefore, we provide a nanofiltration membrane component for salt lake brine treatment to solve the defects of the above solutions. Utility Model Content
