Description

Technical Field

[0001] The utility model relates to the technical field of purified water preparation, in particular to an ultrafiltration device for purified water preparation. Background Art

[0002] Purified water is water for medicinal use made by distillation, ion exchange, reverse osmosis or other suitable methods. It does not contain any additives and is a colorless, clear liquid. Ordinary water contains a variety of ions, such as sodium ions, chloride ions, etc. Some fields in chemistry or physics require extremely pure water that does not contain any ions. Ordinary water cannot meet the needs of some chemical reactions, so the ions in the water are removed through ultrafiltration equipment, and the resulting product is purified water.

[0003] Patent application number "CN202321885021.7" describes "an ultrafiltration device for preparing purified water. It includes a frame on which a device body is arranged, and the device body includes two ultrafiltration cartridges. During rotation, a cam drives the filter membrane cartridge to squeeze the reset spring upward. As the cam continues to rotate, when the protruding end moves away from the filter membrane cartridge, it is driven downward rapidly by the elastic restoring force of the reset spring, which can shake off the substances blocked on the surface, reduce the probability of blockage of the filter membrane cartridge, and improve the preparation efficiency of purified water."

[0004] However, the above-mentioned equipment can only vibrate the ultrafiltration equipment up and down during use. However, since the filter membrane is generally placed vertically inside the ultrafiltration cartridge, the filter membrane can only vibrate up and down during the vertical vibration process, which causes the equipment to only shake off a small amount of blocked material on the surface of the filter membrane.
