AI Technical Summary

Technical Problem

Existing filtration devices are unable to effectively capture small particles or foreign matter dissolved in liquids, resulting in the airflow still containing harmful substances and affecting the cleanliness of the components.

Method used

A negative pressure reverse osmosis filtration device is adopted, which uses reverse osmosis filter elements and a negative pressure environment to filter fluid through the pores of the reverse osmosis filter elements that are smaller than 0.001 microns. Combined with a heat exchange device and a drive device, multiple filtration and temperature regulation of the fluid are achieved.

Benefits of technology

It improves the cleanliness of the fluid, effectively blocking most harmful substances and impurities, extending the service life of components, reducing waste, lowering costs, and improving processing quality.

Abstract

A negative pressure reverse osmosis filtration device and system includes a cylindrical component, a connecting cap, an end cap unit, and a reverse osmosis filter element. The cylindrical component includes two oppositely arranged ends. The connecting cap is disposed at one end and includes two openings. The end cap unit includes an end cap detachably disposed at the other end, the end cap having an inner annular conical surface. The reverse osmosis filter element passes through the cylindrical component and abuts against the connecting cap and the end cap unit. The reverse osmosis filter element defines a conduit and includes an outer annular conical surface abutting against the inner annular conical surface. The reverse osmosis filter element and the cylindrical component define a chamber. The chamber and one of the openings define a first flow channel, and the conduit and the other opening define a second flow channel. One of the first and second flow channels creates a negative pressure state to drive water molecules through the reverse osmosis filter element. The reverse osmosis filter element filters the fluid, thereby improving the fluid cleanliness.
