Description

Technical Field

[0001] The utility model relates to the technical field of liquid resistivity value adjustment, in particular to a resistivity value adjustment device. Background Art

[0002] In the production of semiconductors or liquid crystals, ultrapure water with low resistivity is required to clean the substrate. In the prior art, the resistivity value adjustment device uses a hollow fiber membrane component to dissolve gases such as carbon dioxide or ammonia in ultrapure water, generates ions through dissociation equilibrium, and uses the generated ions to reduce the resistivity value of ultrapure water, thereby obtaining ultrapure water with low resistivity for cleaning the substrate, thereby reducing the situation where the substrate is insulated or particles are attached again.

[0003] The existing resistivity value adjustment device includes a hollow fiber membrane assembly arranged in the inner cavity of the shell, various pipes connected to the interface on the hollow fiber membrane assembly to form a liquid pipeline and a gas pipeline, a solenoid valve arranged on the pipe to control the flow path, and an electrical component electrically connected to the solenoid valve and controlling it. During the working process, ultrapure water needs to be supplied to the hollow fiber membrane assembly, and the adjustment gas is dissolved in the ultrapure water in the hollow fiber membrane assembly, thereby adjusting the resistivity value of the ultrapure water. The existing resistivity value adjustment device uses a partition to separate the inner cavity of the shell, and the hollow fiber membrane assembly and the electrical component are installed separately to achieve water-electricity separation.

[0004] However, during actual use, the inventor conducted in-depth research and found that the hollow fiber membrane assembly of the adjustment device may leak, and the instability of the pipeline connection may also cause leakage. In order to protect the electrical components, the partition not only separates the inner cavity, but also fully ensures the sealing, which is crucial. In order to achieve the sealing between the partition and the shell, if the partition is directly welded and sealed with the inner wall of the shell over a large area, the outer surface of the shell corresponding to the partition welding area may bulge or be damaged over a large area, thereby affecting the appearance and integrity of the outer surface of the shell; and the space accommodating the hollow fiber membrane assembly and the pipeline may store a large amount of accumulated water due to the accumulation of water leakage. The accumulated water will exert pressure on the partition, causing it to shake toward the electrical components, and will also cause a certain degree of damage to the sealed connection between the partition and the shell, causing the seal to fail and lead to safety hazards.

[0005] Therefore, it is necessary to improve the resistivity value adjusting device to ensure the stability and reliability of the sealed connection between the partition and the shell. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a resistivity value adjusting device, which solves the safety problem of electrical components caused by the ultrapure water leaking from the existing resistivity value adjusting device damaging the sealed connection between the partition and the shell.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A resistivity value adjusting device, used for adjusting the resistivity value of ultrapure water, the adjusting device comprising:

[0009] a housing having an inner cavity;

[0010] A hollow fiber membrane assembly is disposed in the inner cavity of the shell;

[0011] A pipeline assembly, comprising a liquid pipeline, a gas pipeline and an electronic control module respectively connected to the hollow fiber membrane assembly;

[0012] An electrical component, electrically connected to the electronic control module;

[0013] A partition extending vertically is provided in the shell to separate the inner cavity of the shell into a first accommodating cavity and a second accommodating cavity, one of the hollow fiber membrane component and the electrical component is located in the first accommodating cavity, and the other is located in the second accommodating cavity;

[0014] The bottom end and the front and rear ends of the partition are respectively sealed and connected to the inner wall of the shell through sealing members, the sealing member at the bottom end of the partition extends along the length direction of the partition, and the sealing members at the front and rear ends of the partition extend along the height direction of the partition and connect with the sealing member at the bottom end of the partition;

[0015] At least one end of the front and rear ends of the partition is fixed with an extension piece, and the extension piece is provided with a through hole;

[0016] The adjustment device further comprises a fixing portion, and the fixing portion at least partially passes through the through hole to fix the extension member and the inner wall of the shell.

[0017] In the resistivity value adjustment device provided by the utility model, the inner cavity of the shell is divided into a first accommodating chamber and a second accommodating chamber distributed on the left and right by a partition, the hollow fiber membrane assembly and the pipeline assembly are placed in the first accommodating chamber, and the electrical assembly is placed in the second accommodating chamber, so as to realize the separation of the hollow fiber membrane assembly and the electrical assembly to meet the water-electricity separation. The bottom end and the front and rear ends of the partition are respectively arranged opposite to the inner wall of the shell. Considering that the leaked water of the first accommodating chamber will flow from the gap between the bottom end and the front and rear ends of the partition to the second accommodating chamber, sealing members are arranged at least at the corresponding positions of the bottom end and the front and rear ends of the partition and the inner wall of the shell. The arranged sealing members shall meet the following requirements: the length of the sealing member at the bottom end of the partition corresponds to the length of the partition, so as to completely seal the gap between the bottom end of the partition and the inner wall of the shell to ensure the sealing performance; the height of the sealing members at the front and rear ends of the partition corresponds to the height of the partition, so as to have a certain distance from the bottom to the top. The gaps between the front and rear ends of the sealing partition and the inner wall of the shell are separated to ensure sealing. The seals at the front and rear ends of the partition must be connected with the seals at the bottom end of the partition, so as to completely seal the gap between the corner of the bottom end of the partition and the inner wall of the shell. The above sealing arrangement and the cooperation between the seals only need to achieve a complete and continuous sealing path in a roughly concave shape between the bottom end, the front and rear ends of the partition and the inner wall of the shell. Therefore, the corresponding meaning of the above can be that the length of the seal is the same as the length of the partition, and the height of the seal can be the same as or different from the height of the front and rear ends of the partition.

[0018] Since the partition will shake or move after being subjected to the leakage water pressure, the front and rear ends of the partition will move and the seal will become unstable. Even if the bottom or top end of the partition is fixed to the shell, it is far from enough because the partition has a certain height and will still shake when subjected to a large amount of leakage water pressure. Then, an extension piece with a through hole and a fixing part at at least one end of the front and rear ends of the partition are connected to the inner wall of the shell. The extension piece, the fixing part and the sealing part are combined to achieve an effective and stable sealed and fixed connection between at least one end of the front and rear ends of the partition and the inner wall of the shell. The extension piece can also increase the contact area with the inner wall of the shell, further improving the connection stability between the partition and the inner wall of the shell. At the same time, the fixing part is limited to pass through the through hole to achieve fixed connection with the shell and the extension piece, so that the volume and area of ​​the fixing part will not It is too large. When the above-mentioned connection and fixing method of the extension piece, through hole, fixing part and the inner wall of the shell is adopted, the extension piece and the inner wall of the shell can have sufficient contact area to ensure a certain connection strength, and the front and rear walls of the shell can be fixed without large-area welding. Even if the fixing part is welded to the inner wall of the shell, the welding area is very small, which can reduce the damage to the surface of the shell caused by welding. At the same time, it reduces the shaking of the partition relative to the shell due to the pressure of leaking water, thereby avoiding the situation where the partition shakes when the hollow fiber membrane assembly leaks water and affects the sealing of the seal. Under the synergistic effect of the seal, the fixing part and the extension piece with the through hole, the partition and the shell have sufficient connection strength to ensure that the seal always plays a sealing role when the partition is subjected to the pressure of leaking water.

[0019] Preferably, the sealing member is an adhesive, and the adhesive is provided at a connection between the partition and the inner wall of the shell, and a part of the adhesive is bonded to the partition, and another part of the adhesive is bonded to the inner wall of the shell.

[0020] With such a configuration, the advantage of the adhesive is that it can adapt to the connection between the end of the partition and the inner wall of the shell. Regardless of the shape and length of the gap formed between the end of the partition and the inner wall of the shell, the adhesive can not only cover and seal the gap at the connection between the end of the partition and the inner wall of the shell, but also fill the gap to enhance the water-proof sealing of the gap; since one part of the adhesive is bonded to the partition and the other part is bonded to the inner wall of the shell, it is ensured that the adhesive can be connected to the partition and the shell at the same time, and the initial connection and positioning of the adhesive to the partition and the inner wall of the shell can be achieved.

[0021] Preferably, the extending member is fixed to the front and rear ends of the partition, the extending member extends along the height direction of the partition, and the extending member abuts against the front and rear inner side walls of the shell.

[0022] With such an arrangement, the front and rear ends of the partition are provided with extension pieces, that is, the front and rear ends of the partition are fixedly connected to the inner wall of the shell, and the extension pieces are extended in the height direction to realize a fixed connection with the partition and the inner wall of the shell at a certain distance, thereby increasing the fixed connection area of ​​the extension pieces with the shell in the height direction, thereby ensuring the connection strength between the front and rear ends of the partition and the inner wall of the shell, and can further reduce the shaking amplitude of the partition relative to the shell, strengthen the stability of the connection between the partition as a whole and the shell, and avoid the shaking of the partition to destroy the sealing effect of the seal itself and cause the connection seal between the partition and the shell to fail; and each extension piece is respectively abutted against the front and rear inner walls of the shell to ensure the contact area between the extension piece and the inner wall of the shell, improve the stability of the fixed installation of the partition and the shell, and can also form a tiny gap beside the gap formed by the front and rear ends of the partition and the inner wall of the shell, so that the path of the gap becomes longer, and cooperates with the seals located at the front and rear ends of the partition and the front and rear inner walls of the shell to further improve the sealing performance of the partition.

[0023] Preferably, the fixing portion includes a first fastener and a second fastener, the first fastener is fixed on the inner wall of the shell and passes through the through hole, the second fastener is arranged on the side of the extension member away from the inner wall of the shell, and the second fastener is detachably connected to the first fastener.

[0024] In this way, the first fastener is fixed on the inner wall of the shell and passes through the through hole. The first fastener is connected to the second fastener within the through hole. The first fastener will not be too large but can ensure sufficient connection strength, thereby achieving a fixed connection between the extension piece and the inner wall of the shell. Even if the first fastener is welded and fixed to the inner wall of the shell, the problem of large-area welding of the first fastener and the inner wall of the shell damaging the outer surface of the shell and leaving marks on the outer surface of the shell can be avoided.

[0025] Preferably, the second fastener abuts against the surface of the extension member away from the inner wall of the shell. In this way, the extension member is pressed as far as possible toward the inner wall of the shell, the gap between the front and rear ends of the partition and the inner wall of the shell is reduced, and the stability of the partition and the shell is improved.

[0026] Preferably, the fixing portion is a welding portion located in the through hole, and the welding portion welds and fixes the inner wall of the through hole to the inner wall of the shell. With this arrangement, the inner wall of the through hole and the inner wall of the shell are directly welded to form a welding portion, which can ensure that the extension part and the inner wall of the shell have a corresponding welding area and connection strength, while avoiding the situation where the deformation caused by the large welding area between the front and rear inner walls of the shell and the partition affects the aesthetic appearance of the shell.

[0027] Preferably, the extending member is fixed to the bottom end of the partition, and the extending member extends along the length direction of the partition.

[0028] With such arrangement, when the partition is shaken by water pressure, the bottom end of the partition will move and will also affect the seal arranged between the bottom end of the partition and the bottom inner wall of the shell. The bottom end of the partition is fixedly connected to the bottom inner wall of the shell through the extension piece at the bottom end of the partition, thereby ensuring the sealing effect of the seal at the bottom end of the partition and making the stability of the connection between the partition and the shell better.

[0029] Preferably, the shell comprises a frame, a top plate, a side plate and a panel, the frame comprises a bottom plate and a circular piece extending upward from the front and rear ends of the bottom plate, the panel is fixed to the outer surface of the circular piece, and the top plate is fixed to the top end of the circular piece;

[0030] The partition is located between the two circular pieces, and the front and rear ends of the partition are respectively in contact with the inner surfaces of the circular pieces, so that a gap is formed between the front and rear ends of the partition and the panel, the adhesive is filled in the gap, and the fixing part is fixed to the panel.

[0031] With such an arrangement, the use of the above-mentioned shell structure can make the shell have better connection strength, but the gap between the end of the partition and the inner wall of the panel will always exist and be large. In addition, there are multiple buttons on the panel. When the buttons are operated, the panel will also be subjected to external force. The panel is deformed by force, which can easily cause the gap to change. Because the deformation of the panel will affect the adhesive sealing connection between the panel and the partition, unless the panel and the partition are welded and sealed, they will be less affected by the deformation of the panel. On the other hand, when there is too much water in the accommodating cavity, the accumulated water will also put pressure on the panel, which will also cause the panel to be deformed by force and affect the adhesive seal between it and the partition. Therefore, the extension piece and the fixing part at the end of the partition are used to fix the circular piece and the panel. The circular piece and the fixing part can hold the panel, and the part of the adhesive filled in the gap can also hold the panel. The panel is not easily deformed by force, which prevents the gap between the partition and the inner wall of the panel from further increasing, which helps to stabilize the size of the gap and avoid tearing the adhesive or causing the sealing connection between the adhesive and the extension piece or the inner wall of the panel to fail, thereby causing failure of water and electricity isolation.

[0032] Preferably, a connecting piece extends inwardly from the top end of the circular piece, and the top end of the partition is fixed to the connecting piece to improve the connection stability between the top end of the partition and the circular piece, and also increase the structural strength of the shell.

[0033] Preferably, the sealing member is located in the first accommodating chamber, and the extension member is located in the second accommodating chamber. With such an arrangement, water leaking from the hollow fiber membrane assembly can be prevented from entering the gap between the partition and the inner wall of the shell from the very beginning, and the water in the gap can be prevented from exerting force on the inner wall of the shell and the end of the partition to expand the gap, thereby preventing the sealing connection of the sealing member from failing. The extension member is located in the second accommodating chamber. When the accumulated water in the first accommodating chamber exerts pressure on the partition, the extension member of the second accommodating chamber is fixedly connected to the inner wall of the shell to transfer the pressure to the shell, and can also provide an opposite force to reduce the deformation or shaking amplitude of the partition, so as to ensure the stability of the seal between the partition and the inner wall of the shell.

[0034] Preferably, the electric control module is inserted through the partition or the shell, and the sealing member is provided at the connection between the electric control module and the partition or the shell. In this way, the electric control module is installed on the partition to avoid the electric control module being suspended in the air, which is not conducive to the installation between the electric control module, liquid pipelines, and gas pipelines. When there is a lot of water leakage in the accommodating cavity where the hollow fiber membrane assembly is installed and accumulates to a certain depth, in order to prevent the leaked water from leaking from the gap at the connection between the electric control module and the partition or the shell to another accommodating cavity or the outside, the sealing member can also play a sealing role.

[0035] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0036] In the resistivity value adjustment device of the utility model, the inner cavity of the shell is divided into a first accommodating chamber and a second accommodating chamber distributed on the left and right by a partition, the hollow fiber membrane assembly and the pipeline assembly are placed in the first accommodating chamber, and the electrical assembly is placed in the second accommodating chamber, so as to realize the separation of the hollow fiber membrane assembly and the electrical assembly to meet the separation of water and electricity. The bottom end and the front and rear ends of the partition are respectively arranged opposite to the inner wall of the shell. Considering that the leaked water of the first accommodating chamber will flow from the gap between the bottom end and the front and rear ends of the partition to the second accommodating chamber, sealing members are arranged at least at the corresponding positions of the bottom end and the front and rear ends of the partition and the inner wall of the shell. The arranged sealing members shall meet the following requirements: the length of the sealing member at the bottom end of the partition corresponds to the length of the partition, so as to completely seal the gap between the bottom end of the partition and the inner wall of the shell to ensure the sealing performance; the height of the sealing member at the front and rear ends of the partition corresponds to the height of the partition, so as to have a certain distance from the bottom to the top. The gaps between the front and rear ends of the sealing partition and the inner wall of the shell are separated to ensure sealing. The seals at the front and rear ends of the partition must be connected with the seals at the bottom end of the partition, so as to completely seal the gap between the corner of the bottom end of the partition and the inner wall of the shell. The above sealing arrangement and the cooperation between the seals only need to achieve a complete and continuous sealing path in a roughly concave shape between the bottom end, the front and rear ends of the partition and the inner wall of the shell. Therefore, the corresponding meaning of the above can be that the length of the seal is the same as the length of the partition, and the height of the seal can be the same as or different from the height of the front and rear ends of the partition.

[0037] Since the partition will shake or move after being subjected to the leakage water pressure, the front and rear ends of the partition will move and the seal will become unstable. Even if the bottom or top end of the partition is fixed to the shell, it is far from enough because the partition has a certain height and will still shake when subjected to a large amount of leakage water pressure. Then, an extension piece with a through hole and a fixing part at at least one end of the front and rear ends of the partition are connected to the inner wall of the shell. The extension piece, the fixing part and the sealing part are combined to achieve an effective and stable sealed and fixed connection between at least one end of the front and rear ends of the partition and the inner wall of the shell. The extension piece can also increase the contact area with the inner wall of the shell, further improving the connection stability between the partition and the inner wall of the shell. At the same time, the fixing part is limited to pass through the through hole to achieve fixed connection with the shell and the extension piece, so that the volume and area of ​​the fixing part will not It is too large. When the above-mentioned connection and fixing method of the extension piece, through hole, fixing part and the inner wall of the shell is adopted, the extension piece and the inner wall of the shell can have sufficient contact area to ensure a certain connection strength, and the front and rear walls of the shell can be fixed without large-area welding. Even if the fixing part is welded to the inner wall of the shell, the welding area is very small, which can reduce the damage to the surface of the shell caused by welding. At the same time, it reduces the shaking of the partition relative to the shell due to the pressure of leaking water, thereby avoiding the situation where the partition shakes when the hollow fiber membrane assembly leaks water and affects the sealing of the seal. Under the synergistic effect of the seal, the fixing part and the extension piece with the through hole, the partition and the shell have sufficient connection strength to ensure that the seal always plays a sealing role when the partition is subjected to the pressure of leaking water.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] As attached Figure 1 and attached Figure 2 As shown, the embodiment of the utility model discloses a resistivity value adjusting device for adjusting the resistivity value of ultrapure water, and the adjusting device comprises a housing 1, a hollow fiber membrane assembly 2, a pipeline assembly 3 and an electrical assembly 4. The housing 1 has an inner cavity for accommodating the hollow fiber membrane assembly 2, the pipeline assembly 3 and the electrical assembly 4 and playing a protective role.

[0056] The hollow fiber membrane assembly 2 is used to adjust the resistivity value of ultrapure water, and includes an outer shell and a hollow fiber membrane (not shown) located inside the outer shell. The hollow fiber membrane separates the hollow fiber membrane assembly 2 into a liquid phase region (not shown) for the circulation of ultrapure water and a gas phase region (not shown) for the circulation of adjusting gas. It should be noted that the hollow fiber membrane assembly 2 is a prior art, and its principle has been disclosed in the prior art and will not be repeated here.

[0057] The pipeline assembly 3 is connected to the hollow fiber membrane assembly 2 and includes a liquid pipeline, a gas pipeline and an electronic control module respectively connected to the hollow fiber membrane assembly 2. The liquid pipeline includes a liquid inlet pipe and a liquid outlet pipe. The liquid inlet pipe is connected to the shell and communicated with the liquid phase area, and is used to input ultrapure water into the liquid phase area; the liquid outlet pipe is connected to the shell and communicated with the liquid phase area, and is used to discharge the ultrapure water in the hollow fiber membrane assembly 2 from the liquid phase area. The gas pipeline includes an air inlet pipe and an exhaust pipe. The air inlet pipe is connected to the shell and communicated with the gas phase area, and is used to input the adjustment gas into the gas phase area. The exhaust pipe is connected to the shell and communicated with the gas phase area, and is used to discharge the adjustment gas or other gases or condensed water from the gas phase area. The adjustment gas in the gas phase area penetrates into the liquid phase area through the hollow fiber membrane and dissolves in the ultrapure water to adjust the resistivity value of the ultrapure water.

[0058] Specifically, the adjustment gas can be a gas such as carbon dioxide or ammonia that can dissolve in ultrapure water and generate ions through dissociation equilibrium, and the ions generated by the dissolution are used to reduce the resistivity value of ultrapure water. The electric control module includes but is not limited to solenoid valves, electric control opening and closing valves, and electric control pressure valves arranged on the liquid pipeline and the gas pipeline, which are used to control the pressure and flow of the fluid inside the pipeline. In addition, manual valves can also be arranged on the liquid pipeline and the gas pipeline. The electrical component 4 is electrically connected to the electrical control module, and the electrical component 4 includes but is not limited to a PLC controller, a power supply, a time relay, and a resistivity meter.

[0059] As attached Figure 1 and attached Figure 2 As shown, the shell 1 of this embodiment is roughly rectangular, and the shell 1 has a length direction (i.e., left-right direction), a width direction (i.e., front-to-back direction) and a height direction (i.e., vertical direction), and a vertically extending partition 5 is provided inside the shell 1. The partition 5 has a length direction (i.e., front-to-back direction) and a height direction (i.e., vertical direction). The partition 5 is located in a roughly central area inside the shell 1, and the front and rear ends of the partition 5 are respectively opposite to the inner walls of the front and rear ends of the shell 1, the bottom end of the partition 5 is opposite to the bottom inner wall of the shell 1, and the top end of the partition 5 is opposite to the top inner wall of the shell 1, thereby dividing the inner cavity of the shell 1 into a first accommodating cavity 15 and a second accommodating cavity 16 distributed on the left and right, the hollow fiber mold assembly 2 and the pipeline assembly 3 are located in the first accommodating cavity 15, the electrical assembly 4 is located in the second accommodating cavity 16, the solenoid valve in the pipeline assembly 3 is electrically connected to the electrical assembly 4, the solenoid valve can be arranged on the partition 5, and a part of the solenoid valve is located in the first accommodating cavity 15, and the other part is located in the second accommodating cavity 16.

[0060] Considering that in actual use, if the hollow fiber membrane assembly 2 and / or the pipeline assembly 3 in the first accommodating chamber 15 leaks, the water will flow from the gap between the bottom end and the front and rear ends of the partition 5 to the second accommodating chamber 16, which will affect the electrical components 4 in the second accommodating chamber 16, not only causing damage to the entire adjustment device, but also causing certain safety hazards. Therefore, a sealing member 53 is provided at least at the corresponding positions of the bottom end and the front and rear ends of the partition 5 and the inner wall of the shell 1, and the bottom end and the front and rear ends of the partition 5 are respectively sealed and connected to the inner wall of the shell 1 through the sealing member 53, and the sealing member 53 at the bottom end of the partition 5 is provided along the length of the partition 5 (referring to Figure 2 The length of the sealing member 53 at the bottom of the partition 5 is roughly corresponding to the length of the partition 5, thereby completely sealing the gap between the bottom of the partition 5 and the inner wall of the shell 1. The sealing members 53 at the front and rear ends of the partition 5 extend in the height direction of the partition 5 (referring to the Figure 2 The sealing member 53 at the front and rear ends of the partition 5 can be connected with the sealing member 53 at the bottom of the partition 5, that is, the height of the sealing member 53 at the front and rear ends of the partition 5 can be consistent with or inconsistent with the height of the partition 5, but the sealing member 53 at the front and rear ends of the partition 5 must be connected with the sealing member 53 at the bottom of the partition 5 to ensure that the gap between the bottom corner of the partition 5 and the inner wall of the shell 1 can also be effectively sealed, thereby completely sealing the gap between the front and rear ends of the partition 5 and the inner wall of the shell 1. As a result, the leaked water in the first accommodating chamber 15 cannot flow into the second accommodating chamber 16 through the gap between the bottom end of the partition 5 and the inner wall of the bottom of the shell 1, and the gap between the front and rear ends of the partition 5 and the inner wall of the front and rear ends of the shell 1, thereby achieving water and electricity isolation between the first accommodating chamber 15 and the second accommodating chamber 16.

[0061] However, during the use of the adjustment device, whether the housing 1 is subjected to external force or the pressure exerted on the partition 5 by the leaked accumulated water ( Figure 2 The water in the middle is pressurized in the left and right directions), which may cause the partition 5 to Figure 2 The water sways in the left and right directions, thereby affecting the sealing performance of the seal 53 between the end of the partition 5 and the inner wall of the shell 1, making the original sealing of the seal 53 ineffective.

[0062] Therefore, in order to avoid or reduce the shaking of the partition 5, at least one of the front and rear ends of the partition 5 is fixed with an extension piece 51, and a through hole 511 is provided on the extension piece 51. The adjustment device also includes a fixing portion 17, and the fixing portion 17 at least partially passes through the through hole 511 to fix the extension piece 51 and the inner wall of the shell 1. The extension piece 51 and the sealing member 53 are combined to realize the fixed connection between the partition 5 and the shell 1. The extension piece 51 can also increase the contact area with the inner wall of the shell 1, and further improve the connection stability between the partition 5 and the inner wall of the shell 1; the above connection method can reduce the surface damage of the shell 1 without welding the front and rear inner walls of the shell 1 in a large area, and can also avoid the shaking of the partition 5 relative to the shell 1 caused by a large amount of water leakage of the hollow fiber membrane assembly 2, so that the partition 5 does not shake easily. Under the synergistic effect of the sealing member 53 and the fixing portion 17, the partition 5 has sufficient connection strength to ensure that the sealing member 53 always plays a sealing role.

[0063] The partition 5 and the extension piece 51 can be arranged in such a way that the extension piece 51 can be formed by welding another plate-like structure with the corresponding end of the partition 5, or by bending and flanging a plate itself to form the partition 5 and the extension piece 51. Preferably, in this embodiment, the partition 5 is formed by bending and flanging a plate, and the extension piece 51 is formed after flanging. The extension piece 51 and the partition 5 are arranged in one piece, which has fewer processing steps, and the structure of the partition 5 is more stable and the appearance of the partition 5 is more beautiful.

[0064] The seal 53 may be a sealing gasket or an adhesive, etc. In other embodiments, when the seal 53 is a sealing gasket, the sealing gasket fills the gap between the end of the partition 5 and the inner wall of the shell 1 and is compressed and deformed to seal. In this embodiment, the seal 53 is an adhesive, which is arranged at the connection between the partition 5 and the inner wall of the shell 1, and one part of the adhesive is bonded to the partition 5 and the other part is bonded to the inner wall of the shell 1. The advantage of the adhesive is that it can be applied to the connection between the partition 5 and the inner wall of the shell 1, one part of the adhesive is bonded to the partition 5 and the other part is bonded to the inner wall of the shell 1, ensuring that the adhesive can be connected to the partition 5 and the shell 1 at the same time. While the adhesive plays a sealing role, it can also play a preliminary connection and positioning role for the connection between the extension 51 and the inner wall of the shell 1, and regardless of the shape and length of the gap between the end of the partition 5 and the inner wall of the shell 1, the adhesive can also be filled in the gap to enhance the water-proof sealing. It should be noted that the adhesive can be selected from glass glue, and the connection strength of glass glue itself to the extension 51 and the inner wall of the shell 1 is not very strong.

[0065] As mentioned above, although the adhesive can play a good sealing role when it is adhered to the partition 5 and the corresponding inner wall of the shell 1 at the same time, the connection effect itself is very low, and it can only play a preliminary positioning role for the partition 5. In addition, the adhesive itself is not hard enough. When the partition 5 is deformed or shaken, the adhesive is easy to tear or detach or break, and lose the waterproof isolation effect. Therefore, in this embodiment, in order to improve the connection strength and stability between the partition 5 and the shell 1, and ensure that the sealing of the sealing member 53 is basically not affected by leakage and pressure, the front and rear ends of the partition 5 are fixed with extension members 51, that is, the front and rear ends of the partition 5 are fixedly connected to the inner wall of the shell 1, further enhancing the connection stability between the partition 5 and the shell 1. In addition, the extension member 51 extends along the height direction of the partition 5 to become a strip, so that the extension member 51 has a certain height distance and is fixedly connected to the inner wall of the shell 1. After the extension member 51 is connected to the inner wall of the shell 1, the stability will be better and it is not easy to shake or deform under water pressure.

[0066] In addition, when the partition 5 at the front and rear ends of the partition 5 abuts against the inner wall of the bottom end of the shell 1, the extension member 51 not only realizes the fixation of the partition 5 and the shell 1, cooperates with the fixing portion 17 and the sealing member 53 to ensure a stable sealing connection between the partition 5 and the inner wall of the shell 1, but also extends the partition 5 and the inner wall of the shell 1. Figure 2 The length of the gap in the left and right directions prolongs the path length of water leakage from the first accommodating chamber 15 into the second accommodating chamber 16, and can also achieve a certain sealing effect.

[0067] In this embodiment, the strip-shaped extension piece 51 abuts against the front and rear inner walls of the shell 1, increasing the connection area between the extension piece 51 and the inner wall of the shell 1, improving the stability of the installation of the partition 5, and further reducing the gap between the front and rear ends of the partition 5 and the inner wall of the shell 1, and cooperating with the seal 53 located at the front and rear ends of the partition 5 and the front and rear inner walls of the shell 1, the sealing performance of the partition 5 is further improved, and the extension piece 51 can also reduce the shaking of the partition 5 relative to the shell 1, avoiding damage to the sealing strength of the seal 53 itself and the connection sealing with the partition 5 and the shell 1.

[0068] Furthermore, the structure of the fixing portion 17 can be various, such as Figure 2 , Attachment Figure 5 and attached Figure 6 As shown, the fixing part 17 includes a first fastener 171 and a second fastener 172. The first fastener 171 is fixed to the inner wall of the housing 1 and passes through the through hole 511. The second fastener 172 is arranged on the side of the extension 51 away from the inner wall of the housing 1. The second fastener 172 is detachably connected to the first fastener 171. In this embodiment, the diameter of the through hole 511 can be 6 mm, and the diameter of the first fastener 171 is 5 mm. The number of the through holes 511 is the same as that of the first fastener 171 and is multiple.

[0069] The first fastener 171 is fixed to the inner wall of the shell 1. This fixing can be that the first fastener 171 is integrally formed on the shell 1, or the first fastener 171 is welded to the inner wall of the shell 1. Because the first fastener 171 has to pass through the through hole 511, the first fastener 171 will not be set to a too large area or volume. No matter which of the above fixing methods is used, it can avoid damaging the outer surface of the shell 1 or leaving as few marks on the outer surface of the shell 1 as possible. After the first fastener 171 passes through the through hole 511, it is connected to the second fastener 172, thereby realizing the fixed connection between the extension 51 and the inner wall of the shell 1. More preferably, the second fastener 172 abuts against the surface of the extension 51 away from the inner wall of the shell 1, pressing the extension 51 to the inner wall of the shell 1 as much as possible, reducing the gap between the front and rear ends of the partition 5 and the inner wall of the shell 1 while improving the stability of the fixation of the partition 5 and the shell 1.

[0070] In a specific embodiment, the first fastener 171 is a stud welded to the inner wall of the housing 1, and the second fastener 172 is a nut, which is screwed onto the stud and abuts against the inner wall of the extension 51. Since the diameter of the stud is very small, the smaller stud is welded to the inner wall of the housing 1 by spot welding, which has little effect on the welding of the inner wall of the housing 1, and basically does not leave any marks on the outer surface of the housing 1. Moreover, the screwing and fixing of the stud and the nut facilitates processing, and the welding gun used for welding is too large and not easy to insert for welding.

[0071] In another specific embodiment, the first fastener 171 is a columnar structure with a slot on the outer surface, and the portion of the columnar structure with the slot is extended into the through hole 511. The second fastener 172 is a limit card, which is stuck in the slot. At the same time, the limit card presses against the inner wall of the extension 51 to achieve a stable and non-shaking connection. At this time, the diameter of the first fastener 171 is smaller to avoid damaging the outer surface of the shell 1 or leaving as few marks on the outer surface of the shell 1 as possible.

[0072] In another embodiment, the fixing portion 17 is a welding portion located in the through hole 511, and the welding portion is formed by the solder extruded after the inner wall of the through hole 511 is welded and fixed to the inner wall of the shell 1. The welding area between the inner wall of the through hole 511 and the shell 1 will not be too large, but it can ensure the connection strength between the extension piece 51 and the shell 1 while avoiding deformation of the front and rear surfaces of the shell 1, and will not affect the appearance of the device.

[0073] In this embodiment, an extension piece 51 is fixed to the bottom end of the partition 5. The extension piece 51 extends along the length direction of the partition 5 ( Figure 2The middle partition 5 extends in the front-to-back direction), and in addition to at least one end of the front and rear ends of the partition 5 being fixedly connected to the inner wall of the shell 1 without much damage through the extension piece 51 and the fixing part 17, it can effectively limit the shaking amplitude of the partition 5 when it is subjected to water pressure on the left and right sides, and can also fix the bottom end of the partition 5 to the inner wall of the shell 1. It can also ensure the sealing connection between the bottom end of the partition 5 and the inner wall of the shell 1, and make the installation connection of the entire partition 5 stable.

[0074] In addition, the seal 53 can be arranged between the extension 51 and the inner wall of the bottom of the shell 1. For example, the seal 53 is a sealing gasket. The sealing gasket is deformed by the extension 51 to increase the sealing area, further improving the sealing effect. The seal 53 can also be arranged between the end of the partition 5 and the inner wall of the shell 1 without contacting the extension 51. For example, the seal 53 is an adhesive coated on the end of the partition 5 and the inner wall of the shell 1 for sealing connection. The extension 51 further strengthens the connection between the partition 5 and the shell 1 through the fixing part 17 to prevent the sealing failure of the seal 53 caused by the shaking of the partition 5.

[0075] As attached Figure 2 As shown, the housing 1 includes a frame 11, a top plate 12, a side plate 13 and a panel 14. The frame 11 includes a bottom plate 111 and a circular piece 112 extending upward from the front and rear ends of the bottom plate 111. Each panel 14 is fixed to the outer surface of each circular piece 112. The panel 14 has two circular pieces 112 located in the front and rear directions. The top of the circular piece 112 is also fixedly connected to the partition 5. A connecting piece 113 extends inwardly from the top of the circular piece 112. The top of the partition 5 is fixed to the connecting piece 113 to improve the connection stability between the partition 5 and the housing 1, prevent the partition 5 from shaking during the use of the device and destroying the seal, and also increase the structural strength of the housing 1.

[0076] In some actual products, the partition 5 is located between the two circular pieces 112, and only the top of the partition 5 is fixedly connected to the top of the circular piece 112, and adhesive is coated at the connection between the front and rear ends and the bottom end of the partition 5 and the inner wall of the shell to seal the gap and connect. The front and rear ends and the bottom end of the partition 5 are fixed to the shell 1 with adhesive. Such a structure will cause the fixation of the partition 5 to be unstable and easy to shake. In addition, since some buttons or connectors connected to external devices are generally provided on the panel 14, and since the panel 14 is made of sheet metal, when the buttons or connectors thereon are operated, the panel 14 may be deformed, thereby causing the gap between the partition 5 and the inner wall of the panel 14 to change, and the adhesive may be deformed due to force, and the adhesive may be damaged, resulting in sealing failure; in addition, the force on the panel 14 may also be transmitted to the partition 5, causing the partition 5 to move, the adhesive is damaged, and the gap between the partition 5 and the inner wall of the shell 1 becomes larger, resulting in sealing failure.

[0077] Therefore, in this embodiment, the partition 5 is located between the two circular pieces 112, and the front and rear ends of the partition 5 are respectively abutted against the inner surfaces of the circular pieces 112 on the corresponding sides, so that a gap is formed between the front end of the partition 5 and the front panel 14, and the rear end and the rear panel 14, and the adhesive is filled in the gap. At the same time, the partition 5 is connected to the panel 14 at the same time through the fixing part 17. On the one hand, the circular piece 112 and the panel 14 are fixed by the extension pieces 51 and the fixing parts 17 at the front and rear ends of the partition 5, and the panel 14 is not easily deformed by force, which is helpful to stabilize the gap and control the gap between the partition 5 and the panel 14 to basically not change; on the other hand, when there is too much water accumulated in the first accommodating chamber 15 and pressure is applied to the partition 5 to cause the partition 5 to deform, the circular piece 112 and the fixing part 17 can pull the panel 14 to prevent the gap between the partition 5 and the inner wall of the panel 14 from further increasing, thereby preventing the adhesive from being torn or the sealing connection between the adhesive and the extension piece 51 or the inner wall of the panel 14 from failing, thereby causing the overall sealing failure of the seal 53.

[0078] In this embodiment, the top plate 12 is fixed to the top of the two circular pieces 112, covering the top of the frame 11 and the top of the partition. The two side panels 13 are respectively connected to the left and right sides of the two circular pieces 112, covering the left or right side of the frame 11. The top plate 12 and the side panels 13 are an integrated structure to form an L-shaped plate, which has a more stable structure. Of course, in other embodiments, the top plate 12 and the side panels 13 are independent plate structures, which are respectively fixedly connected to the circular pieces 112.

[0079] As attached Figure 4 As shown, the seal 53 is located in the first accommodating chamber 15, which can prevent water leakage of the hollow fiber membrane assembly 2 from entering the gap between the partition 5 and the inner wall of the shell 1 from the beginning. Figure 7 In the embodiment shown, the seal 53 is an adhesive, which is applied to the bottom end of the partition 5 and extends along the length direction (front and rear direction) of the partition 5. The adhesive is applied to the front and rear ends of the partition 5 in the height direction. The height on the front and rear ends of the partition 5 can be consistent with the height of the partition 5, and the adhesive on the front and rear ends of the partition 5 and the adhesive at the bottom end of the partition 5 are connected and transitioned, so the adhesives at the front and rear ends and the bottom end of the partition 5 are combined into a shape similar to a concave character to seal the front and rear ends and the bottom end of the partition 5 and the inner wall of the shell 1. Of course, in other embodiments, the extension height of the adhesive at the front and rear ends of the partition 5 can also be lower than the height of the partition 5, as long as it can meet the water and electricity isolation requirements to a certain extent.

[0080] As attached Figure 4As shown, the extension piece 51 is located in the second accommodating chamber 16. When the accumulated water in the first accommodating chamber 15 applies pressure to the partition 5, the extension piece 51 is connected and fixed to the inner wall of the shell 1. On the one hand, the pressure is transmitted to the shell 1. On the other hand, when the partition 5 is under pressure, the extension piece 51 can also provide an opposite force to prevent the partition 5 from deforming or shaking, so as to ensure the stable sealing between the partition 5 and the inner wall of the shell 1.

[0081] In addition, a notch 52 is formed at the corner of the partition 5, i.e., at the junction of the bottom end of the partition 5 and the extension pieces 51 at the front and rear ends. In order to improve the waterproof sealing effect, a sealing piece 53 is also provided in the notch 52, i.e., coated with adhesive.

[0082] Finally, the electric control module is inserted through the partition 5 or the housing 2, and a seal 53 is provided at the connection between the electric control module and the partition 5 or the housing 2. In this way, the electric control module is installed on the partition 5 to avoid the electric control module being suspended in the air, which is not conducive to the installation between the electric control module, the liquid pipeline, and the gas pipeline. When the water leakage in the accommodating cavity where the hollow fiber membrane assembly 2 is installed is large and accumulates to a certain depth, when the electric control module (such as a solenoid valve) is inserted through the partition 5, the attached Figure 3 It can be seen that one part of the solenoid valve is located in a accommodating chamber equipped with a hollow fiber membrane component 2 and connected to the pipeline, and the other part is located in a accommodating chamber equipped with an electrical component 4 and connected between the electrical component. Therefore, in order to avoid a certain depth of leakage of water from the gap at the connection between the solenoid valve and the partition 5 to the accommodating chamber equipped with the electrical component 4, a seal 53 is used to seal the gap at the connection between the solenoid valve and the partition 5. The seal 53 here includes but is not limited to sealing gaskets, O-rings, adhesives, etc.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
