Problems solved by technology

This structure results in a small number of water inlet holes on the central tube and a small water intake, which affects the filtered water flow rate and water volume.
[0005] In addition, in the existing water purification equipment, when the central tube wrapped with the diaphragm is taken out of the membrane shell for replacement or maintenance, it is necessary to apply force from one end of the central tube
Due to the tight seal between the center tube and the membrane shell, a relatively large force needs to be applied when taking it out, and due to the structural limitations of the existing center tube itself, it is impossible to find a suitable force application point when applying force, and it is very difficult to operate even with tools. Inconvenient, or even damage, causing a lot of inconvenience for replacement and repair

Embodiment Construction

[0038] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] figure 1 , figure 2 As shown, the integrated composite roll-type membrane provided by the present invention is installed in a standard membrane housing 12 . It includes an RO reverse osmosis membrane 13 and a hollow central pipe 15 wound with the RO reverse osmosis membrane 13 . The central pipe 15 is provided with several water inlet holes 4 , and the water filtered by the RO reverse osmosis membrane 13 enters the pure water inlet chamber 10 of the central pipe 15 through the water inlet holes 4 .

[0040] The inner diameter of the center pipe 15 is set according to the diameter of the coiled membrane casing 12 , and an activated carbon filter element 14 is installed in the pure water inlet cavity 10 of the center pipe 12 .

[0041] The coiled membrane composed of a membrane and a hollow central tube woun...

Abstract

The invention discloses an integrated composite spiral-wound membrane. The integrated composite spiral-wound membrane is arranged in a spiral-wound membrane housing, and comprises a spiral-wound membrane which is mainly composed of a membrane sheet and a hollow center tube used for winding the membrane sheet; the hollow center tube is provided with a plurality of water inlets; water filtered via the membrane sheet is delivered into a tube chamber of the hollow center tube; the diameter of the hollow center tube matches the tube diameter of the spiral-wound membrane housing; and a filter material is arranged in the tube chamber of the hollow center tube. The integrated composite spiral-wound membrane is capable of reducing whole machine size, increasing water yield, and is convenient for dismounting.

Description

technical field [0001] The invention relates to a water filtering device, in particular to an integrated composite roll-type membrane structure. Background technique [0002] With the rapid development of the country's industrialization, water pollution has become a major problem that the country needs to solve urgently. People's pursuit of a healthy life forms a sharp contradiction with the deteriorating domestic drinking water. In order to solve the current situation of drinking water, reverse osmosis pure water machines are favored by users. [0003] The structure of the existing water purification equipment is: the diaphragm is wound on the center pipe in circles, and then the center pipe is installed in the membrane shell. The diameter of the membrane shell is standard and fixed in the industry. The inner diameter of the center pipe is usually very small, and several water inlet holes are opened on it. The water filtered by the membrane enters the cavity of the cent...
