[0002] At present, in the field of membrane concentration and separation technology, the end seal of the separation membrane shell adopts a common O-ring seal. Some raw liquid media are prone to crystallization in the sealing area. Due to the long-term accumulation of crystals, the O-ring seal of the sealing plate may fail and leak, causing corrosion of the outer stressed metal parts.
[0003] With the continuous expansion of the application field of membrane concentration and separation technology, the components of the treated media are becoming more and more complex, and the sealing requirements for the end parts of the separation membrane shell are becoming higher and higher. At present, the commonly used sealing structures in this field are prone to crystallization in the sealing area, and leakage is becoming more and more common. Utility Model Content

[0007] Furthermore, the tube body includes: a first fixed tube and a second fixed tube, the first fixed tube and the second fixed tube are arranged at both ends of the main body and extend into the main body; a connecting tube, arranged between the first fixed tube and the second fixed tube, and the variable diameter structure is the connecting tube.
[0008] Further, the diameter of the first fixed tube is greater than the diameter of the second fixed tube.
[0009] Furthermore, two grooves are provided on the outer edge of the body, and the sealing member is arranged in the grooves.
[0010] Furthermore, the sealing member is an O-ring.
[0011] Furthermore, the main body and the tube body are an integrally formed part.

[0029] The preferred embodiments of the present disclosure are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.
[0030] See also Figures 1 to 4As shown, the utility model provides a separation membrane housing sealing plate suitable for crystallization media, comprising: a main body 1, which is a plate-like structure; a tube body 2, which is arranged at both ends of the main body 1, and the tube body 2 is provided with a variable diameter structure, and the variable diameter structure is located in the main body 1; a first guide channel 3 and a second guide channel 4, which are obliquely arranged in the main body 1, the first guide channel 3 is connected to the variable diameter structure, and the second guide channel 4 is connected to the tube body 2; a guide groove 5, and the guide groove 5 is arranged on the outer edge of the main body 1; a seal 6, which has two, and the two seals 6 are arranged on the outer edge of the main body 1, and the seal 6 is used to seal the guide groove 5.
[0031] By arranging a tube body 2 at both ends of the main body 1 and arranging a variable diameter structure inside the tube body 2, the first guide channel 3 can be used to communicate with the variable diameter structure, the second guide channel 4 can be connected to the tube body 2, and a guide groove 5 is arranged on the outer edge of the main body 1, so that the separated concentrated liquid flows out through the concentrated water outlet, enters the main body 1 through the tube body 2 and the variable diameter structure, and the separated concentrated liquid enters the guide groove 5 through the first guide channel 3, and then flows out through the second guide groove 5. The membrane center of the separation membrane shell is small molecule permeate, and the small molecule permeate enters the guide groove 5 through the first guide channel 3 for circulation, and then flows out through the second guide groove 5 back to the tube body 2 to flow out. In this way, it can effectively avoid the formation of crystals in the second seal 6 area when the first seal 6 fails, resulting in leakage due to seal failure and corrosion of metal pressure-bearing parts.
[0032] In this embodiment, the first guide channel 3 and the second guide channel 4 are arranged in parallel. Since the first guide channel 3 and the second guide channel 4 are arranged obliquely relative to the main body 1, the inclination angles of the first guide channel 3 and the second guide channel 4 relative to the main body 1 are consistent.
[0033] Of course, the inclination angles of the first guide channel 3 and the second guide channel 4 relative to the main body 1 may be different; specifically, they can be set according to actual conditions.
[0034] In some optional embodiments, the tube body 2 includes: a first fixed tube 7 and a second fixed tube 8, which are arranged at both ends of the main body 1 and extend into the main body 1; a connecting tube 9, which is arranged between the first fixed tube 7 and the second fixed tube 8, and the variable diameter structure is the connecting tube 9.
[0035] By providing the first fixed pipe 7 and the second fixed pipe 8 and connecting them to the body 1 , the separated concentrated liquid passes through the first fixed pipe 7 and the connecting pipe 9 , and then passes through the first guide channel 3 and the second guide channel 4 , and is discharged from the second fixed pipe 8 .
[0036] The diameter of the first fixing tube 7 is larger than the diameter of the second fixing tube 8. This arrangement is adapted to the connecting tube 9.
[0037] Specifically, the diameter of the first fixed pipe 7 is φD, and the diameter of the second fixed pipe 8 is φd. According to the law of conservation of energy in fluid mechanics, under a certain pressure P, the smaller the pipe diameter, the greater the flow rate and the greater the loss along the way, φD>φd, that is, the pressure at the first fixed pipe 7 is greater than the pressure at the second fixed pipe 8, and the small molecule permeate enters the guide groove 5 through the first guide channel 3 for circulation, and then flows out through the second guide groove 5 and returns to the tube body 2 to flow out. This can effectively avoid the formation of crystals in the second seal 6 area when the first seal 6 fails, resulting in leakage due to seal failure and corrosion of metal pressure-bearing parts.
[0038] In some optional embodiments, two grooves 10 are provided on the outer edge of the body 1, and the seal 6 is provided in the grooves 10. The provision of the grooves 10 facilitates the installation of the seal 6 in the grooves 10, that is, provides installation space for the seal 6.
[0039] Specifically, the sealing member 6 is an O-ring.
[0040] In some optional embodiments, the body 1 and the tube 2 are integrally formed. The body 1 and the tube 2 integrally formed by injection molding can ensure the overall strength of the sealing plate and the stability of the sealing plate in use.
[0041] The utility model also provides a separation membrane housing, which is a separation membrane housing sealing plate suitable for crystallization media; it also includes: a shell 11, a main body 1 is sleeved in the shell 11, and a positioning groove 12 is provided on the inner wall of the shell 11; a support block 13, which is arranged in the shell 11 and abuts against the main body 1, and the support block 13 is used to support the shell 11; a stopper 14, which is arranged in the positioning groove 12 and abuts against the support block 13.
[0042] The housing 11 is made of glass fiber reinforced plastic. Specifically, the housing 11 is made of a glass fiber reinforced plastic blank by grinding and turning; the support plate is formed by casting; the stopper 14 is formed by casting;
[0043] When preparing the separation membrane shell: the first step is to assemble the sealing plate, the support plate and other accessories; the second step is to install the assembled end plate into the glass fiber reinforced plastic shell 11, install the stopper 14, and the separation membrane shell is prepared.
[0044] When the separation membrane housing is in use: due to the design of the first guide channel 3 and the second guide channel 4, the circulation dilution of the liquid between the two seals 6 can be achieved to avoid the formation of crystals and ensure that the medium does not leak, thereby ensuring the good corrosion resistance and sealing performance of the separation membrane housing.
[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
