Description

Technical Field

[0002] Pure water equipment is a water treatment equipment that uses pretreatment, reverse osmosis technology, ultrapurification treatment and post-treatment methods to almost completely remove the conductive medium in the water, and remove the non-dissociated colloids, gases and organic matter in the water to a very low level. However, the ultrapure water equipment needs to use a filter to filter the water during the pretreatment step; Patent No. CN202120084459.X discloses a filter for an ultrapure water device, including a filter body, which is used for the ultrapure water device filter. The fixed frame and the filter screen are fixed by a pin rod to make its installation more convenient and stable, and then the mounting plate is installed inside the mounting groove. At this time, the threaded rod is rotated so that one end of the threaded rod is threadedly connected to the inside of the threaded groove, and the mounting plate is fixed by the threaded rod to prevent it from shaking during use, causing water leakage inside the filter body. When the filter screen needs to be replaced, the above operation is performed on the contrary, thereby achieving the purpose of more convenient use and higher replacement efficiency.

[0003] The disadvantage of the above disclosed filter is that a single filter screen cannot guarantee good filtering accuracy when filtering water, and the filter screen is connected and fixed with threaded rods, which is not convenient for disassembly.
