[0002] In the field of water treatment technology, the reverse osmosis method has rapidly occupied the market with its advantages of simple equipment, easy maintenance, and equipment modularization. It is not only applicable to seawater desalination but also suitable for brackish water desalination. The characteristic of reverse osmosis membrane separation is its "broad-spectrum" separation, that is, it can not only remove various ions in water but also remove particles larger than ions, such as most organic matters, colloids, viruses, bacteria, suspended solids, etc. Therefore, the reverse osmosis separation method is also known as the broad-spectrum separation method.

[0003] The reverse osmosis membrane housing is the core pressure vessel of the reverse osmosis system, and the quality of its sealing will affect the reliability and maintainability of the entire reverse osmosis system.

[0004] However, the sealing effect of the shell cover used to isolate the unfiltered liquid and the filtered liquid in the existing reverse osmosis membrane housing is poor, making it easy for the external unfiltered liquid to directly enter the interior of the membrane housing, resulting in the mixing of the unfiltered liquid and the filtered liquid, and it is not easy to be discovered, thus affecting the quality of water treatment. Summary of the Invention

That is, unless specifically stated otherwise, each feature is only an example of a series of equivalent or similar features.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an anti-mixing reverse osmosis membrane housing of the present utility model includes a membrane housing 1. One end of the membrane housing 1 is provided with a housing cover 16. A liquid inlet pipe 6 is installed on the housing cover 16. A sealing sleeve 3 is installed near the housing cover 16 of the membrane housing 1. One end of the sealing sleeve 3 wraps around the outside of the housing cover 16, and one end of the sealing sleeve 3 tapers inward to form a sealing part 5. The sealing part 5 is sleeved on the outside of the liquid inlet pipe 6. A fixing plate 8 is installed on the outer wall surface of the membrane housing 1. A chute is provided on the inner side surface of the fixing plate 8. A slider 7 is slidably installed in the chute. A C-shaped piece 4 that presses the sealing part 5 and the sealing sleeve 3 is movably installed on the slider 7. Limiting plates 9 that press the C-shaped piece 4 inward are installed on both sides of the fixing plate 8.

[0025] In this embodiment, the bottom surface of the C-shaped piece 4 abuts against the top surface of the sealing sleeve 3. The inner side surface of the sealing sleeve 3 abuts against the top surface of the housing cover 16. The inner circumferential surface of the C-shaped piece 4 abuts against the outer circumferential surface of the sealing part 5. The inner circumferential surface of the sealing part 5 abuts against the outer circumferential surface of the liquid inlet pipe 6.

[0026] In this embodiment, a plurality of positioning grooves 13 are provided on the outer surface of the slider 7, and positioning blocks 14 are installed at both ends of the C-shaped piece 4 corresponding to the positioning grooves 13. The positioning blocks 14 are slidably set in the positioning grooves 13. The cross-sections of the positioning blocks 14 and the positioning grooves 13 are both arranged in a trapezoidal structure, so that the positioning blocks can only move along the positioning grooves, thereby preventing the positioning blocks from detaching from the positioning grooves.

[0027] In this embodiment, the top surface of the limiting plate 9 is provided with a guide portion 10 in an inclined manner, and the bottom of the limiting plate 9 is bent and installed on the side surface of the fixing plate 8 .

[0028] In this embodiment, a screw hole 15 is vertically provided on the slider 7, a bearing is embedded on the bottom surface of the slide groove, an axial hole is provided on the top surface of the slide groove, a screw 11 is threadedly connected in the screw hole, one end of the screw 11 is installed in the inner ring of the bearing, and the other end extends through the axial hole to the outer casing, and a handwheel 12 is installed.

[0029] In this embodiment, the cross-sections of the slide groove and the slider 7 are arranged in a "T"-shaped structure, so that the slider can only move up and down along the slide groove, thereby preventing the slider from detaching from the slide groove.

[0030] In this embodiment, the C-shaped piece 4 is made of elastic metal material, so that the C-shaped piece has an outward elastic force. After moving out from between the limiting plates, the outward spring sheet can open the C-shaped piece outward and make the positioning block move outward along the positioning groove.

[0031] In this embodiment, a fixing ring 2 is installed near the sealing sleeve 3 of the membrane shell 1. The fixing ring 2 is fixedly connected to the sealing sleeve 3 to increase the contact area with the sealing sleeve and avoid the sealing sleeve from warping below and affecting the sealing quality.

[0032] During installation, after the shell cover is installed, the sealing sleeve can be stretched outward and sleeved on the shell cover, and the sealing part can be sleeved on the liquid inlet pipe. After the above is completed, the hand wheel is rotated, and the rotation of the hand wheel drives the screw rod, and the rotation of the screw rod drives the slider to move downward along the slide groove. The movement of the slider synchronously drives the positioning block and the C-type piece until the C-type piece is in contact with the top surface of the sealing sleeve. The C-type piece can increase the sealing between the membrane shell and the sealing sleeve, and as the C-type piece moves, the outer side of the C-type piece will be contacted by the guide part, so that the C-type piece is clamped inward until the C-type piece is clamped on the outside of the sealing part, thereby increasing the sealing between the liquid inlet pipe and the sealing part, thereby effectively sealing the membrane shell and the shell cover, and preventing the liquid to be filtered from entering the interior of the membrane shell.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
