Description

Technical Field

[0001] The utility model relates to the technical field of water treatment and purification, and particularly relates to a composite structure of an ultrafiltration membrane and a carbon filter element. Background Technique

[0002] A water treatment device is a device used to improve water quality. Its working principle mainly includes physical methods, chemical methods, and biological methods. In physical methods, the water treatment device uses devices such as filters, sedimentation tanks, and centrifugal settlers to remove suspended solids, impurities, and particulate matter in water. Through filters or media with different pore sizes, the suspended solids in water can be effectively filtered out, making the water clear and transparent.

[0003] Currently, an external pressure ultrafiltration membrane is often used for water filtration. The working principle of the external pressure ultrafiltration membrane is that the influent water flows through the outside of the hollow membrane filaments of the ultrafiltration membrane and penetrates into the inside of the membrane filaments under external pressure to become the permeate, while the concentrated water is discharged outside it. The characteristic of this filtration method is that the influent side is outside the membrane filaments, and the inner cavity is clean product water, so the inner cavity will not be blocked. However, after the ultrafiltration membrane is used for a period of time, a large amount of impurities will adhere to its outside, which easily affects the penetration of the water source, and the filtration effect will decline after long-term use. It needs to be replaced or cleaned regularly, which is time-consuming and laborious.

[0004] Therefore, we propose a composite structure of an ultrafiltration membrane and a carbon filter element. Content of the Utility Model

[0022] In one embodiment provided by the present utility model, the connecting cylinder 4 is located directly below the external convex body 3, and the connecting cylinder 4 and the diversion pipe 6 are of a through structure. The diversion pipe 6 can facilitate the derivation of the purified water source when in use.

[0023] In another embodiment provided by the present utility model, the disassembly and assembly head 5 and the external thread 10 are of an integrally formed structure, and the connecting cylinder 4 and the internal thread 11 are of an integrally formed structure. The external thread 10 can be threadedly connected to the internal thread 11 when in use, facilitating the disassembly and assembly between the disassembly and assembly head 5 and the connecting cylinder 4.
