Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to an ultrapure water equipment which is convenient for replacing an RO reverse osmosis membrane. Background Art

[0002] Ultrapure water was originally produced by the US scientific community using distillation, deionization, reverse osmosis, or other appropriate supercritical fine technology to develop ultrapure materials (such as semiconductor components and nano-fine ceramics). Today, ultrapure water is widely used in the fields of biology, medicine, and automobiles. Besides water molecules (H2O), this water contains virtually no impurities, including bacteria, viruses, organic matter like chlorinated dioxins, and essential minerals and trace elements. Ultrapure water has no hardness and tastes sweet, often referred to as soft water. It can be drunk directly or boiled.

[0003] Ultrapure 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 colloidal substances, gases and organic matter in the water to a very low level. During the use of ultrapure water equipment, the RO reverse osmosis membrane needs to be replaced frequently. In the existing technology, the RO reverse osmosis membrane and the ultrapure water equipment are connected by threads. When replacing the RO reverse osmosis membrane, the RO reverse osmosis membrane needs to be disassembled with a disassembly tool. The internal space of the ultrapure water equipment is small, and the disassembly of the RO reverse osmosis membrane is relatively cumbersome, which leads to the inconvenience of disassembling the RO reverse osmosis membrane, thereby affecting the disassembly efficiency.

[0029] Working principle: The utility model is an ultrapure water equipment which is convenient for replacing RO reverse osmosis membrane. During use, by opening the cover plate 5 and then moving the pressing plate 14 upward, the pressing plate 14 drives the cross plate 16 to move upward on the outer edge of the limit rod 18, and at the same time the compression spring 19 is squeezed, and then the RO reverse osmosis component 10 is moved to the inner cavity of the groove 15 at the top of the supporting plate 11. At this time, the RO reverse osmosis component 10 is located directly under the pressing plate 14. Then, the force on the pressing plate 14 is slowly released, and the pressing plate 14 moves downward under the action of gravity and the compression spring 19. The pressing plate 14 moves downward to the top of the RO reverse osmosis component 10, and the top of the RO reverse osmosis component 10 and the bottom of the inner cavity of the groove 15 at the bottom of the pressing plate 14 fit together, thereby completing the installation of the RO reverse osmosis component 10. Then, the water inlet pipe 12 and the water outlet pipe 13 are connected to the RO reverse osmosis component 10 by threads, and the water is filtered through the RO reverse osmosis component 10.

[0030] When disassembling the RO reverse osmosis component 10, first unscrew the water inlet pipe 12 and the water outlet pipe 13, then move the pressing plate 14 upward, the pressing plate 14 drives the cross plate 16 to move upward along the outer edge of the limit rod 18, and at the same time the compression spring 19 is squeezed, the pressing plate 14 moves away from the RO reverse osmosis component 10, and then the RO reverse osmosis component 10 is moved away from the supporting plate 11, thereby disassembling the RO reverse osmosis component 10, which is simple and convenient to operate;

[0031] When the cover plate 5 is closed, the cover plate 5 is fixed by the adsorption action of the first magnet 8 and the second magnet 9 .
