Description

Technical Field

[0001] This invention belongs to the field of membrane filtration technology, and specifically relates to a novel caustic soda brine membrane filtration component with good cleaning and maintenance effects and is detachable. Background Technology

[0002] Membrane filtration technology, also known as pressure-driven membrane separation technology, is an advanced method for deep water treatment. Under certain pressure, when the feed solution flows over the membrane surface, the numerous tiny pores on the membrane surface allow only water and small molecules to pass through, becoming the permeate. Substances in the feed solution with a volume larger than the pore size are retained on the feed side of the membrane, becoming the concentrate. This achieves the separation and concentration of the feed solution.

[0003] In the process of using membrane filtration modules to filter industrial water, multiple sets of membrane filtration modules need to be used in combination. Existing membrane filtration modules are inconvenient to maintain and clean when a single set is needed, and they do not have a function for feedback on the internal pressure of the filter module. Based on this, we propose a new type of caustic soda brine membrane filtration module with good cleaning and maintenance effect and is detachable. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. With the inlet pipe in place, during use, the user first connects the inlet pipe and outlet pipe to the pipe requiring the filtration component. Simultaneously, valve two is closed and valve one is opened, allowing the water to be filtered to flow from the inlet pipe into the cylinder. Under the spiral guidance between the threaded plate and the inner sleeve, the water flows into the bottom of the inner sleeve and then into the inner side of the inner sleeve through the inlet hole. After being pressured by the water flow, the water flows through the inclined filter plate and metal filter screen to reduce the clogging of large particles. Then, through the multi-layer filtration of the SST filter membrane module, the water finally flows through the inner cylinder and outlet pipe to the next component. The overall filtration efficiency is high, and it can be installed upside down or square according to needs for easy filtration.

[0022] 2. With the U-tube in place, when disassembly, cleaning, and maintenance are required, first connect the U-tube to one end of the next outlet pipe via the flange plate and bolt assembly. Then, close valve one and open valve two inside the U-tube to guide the water flow around the inside of the cylinder and into the next filter assembly. Afterward, insert the bolts inside the top cover and flange plate one to lift the inner cylinder out of the cylinder and remove the spherical shell. Clean the large particles remaining inside the spherical shell and cylinder. Rotate the inclined filter plate to remove the inclined filter plate and metal filter screen, allowing the mounting ring and SST filter membrane assembly to be removed for cleaning and maintenance. This increases the convenience of disassembly and assembly without affecting the operation of other filter components, making maintenance easy and improving performance.

[0023] 3. With the piston in place, during use, water pressure flows through the inclined filter plate and metal filter screen to the bottom and inside of the piston. The pressure is transmitted upward through the support rod sliding limit on the inside of the mounting ring, and then through the flange plate squeezing the spring, causing the conductive block to slide inside the resistance winding. The current and voltage changes of this section can be measured by connecting the conductive block and the resistance winding with wires, thus indirectly determining the internal water pressure. This adds the function of detecting different filter components during use, resulting in good overall performance. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-5As shown, a novel caustic soda brine membrane filter assembly with good cleaning and maintenance performance and detachable assembly includes a cylindrical body 1. A flange plate 25 is fixedly installed on the outer side of the top of the cylindrical body 1. An inner sleeve 24 is fixedly installed inside the cylindrical body 1. Several inlet holes 21 are opened inside the bottom of the inner sleeve 24. An inner cylinder 15 is movably sleeved on the inner side of the inner sleeve 24. A top cover 10 is fixedly installed on the top of the inner cylinder 15. Several fastening bolts 11 are movably inserted into the inside of the top cover 10. A sealing ring is fixedly sleeved on the outer side of the inner cylinder 15. Gasket 16, a spherical shell 3 is movably installed at the bottom of the cylinder 1, flange plate 4 is fixedly installed at the connection between the spherical shell 3 and the cylinder 1, a base plate 2 is fixedly installed at the bottom of the spherical shell 3, an elastic telescopic column 22 is fixedly installed at the bottom of the inner cavity of the spherical shell 3, a soft ball 33 is fixedly installed at the top of the elastic telescopic column 22, a threaded plate 19 is fixedly installed on the opposite side of the inner sleeve 24 and the cylinder 1, an inlet pipe 7 is connected to one side of the top of the cylinder 1, an outlet pipe 8 is connected to one side of the inlet pipe 7, and the inner... The inner sleeve 15 is equipped with valve 6. A U-tube 13 is connected to one side of the inlet pipe 7. Valves 9 are installed inside both the outlet pipe 8 and the U-tube 13. A water outlet pipe 12 is connected to one side of the top of the inner cylinder 15. An inclined filter plate 23 is threadedly connected to the bottom of the inner sleeve 24. A metal filter screen 20 is fixedly installed on the top of the inclined filter plate 23. Several mounting rings 30 are movably installed on the top of the metal filter screen 20. An SST filter membrane assembly 31 is installed inside the mounting rings 30. A movably fitted inner side of the mounting rings 30 is... A piston 32 is attached to a support rod 26 at its top. A ring plate 25 is attached to the outside of the support rod 26. A partition plate 17 is movably sleeved on the outside of the support rod 26. Several support columns 18 are fixedly installed at the bottom of the partition plate 17. A sleeve 28 is movably sleeved on the top of the support rod 26. A resistance winding 27 is sleeved inside the sleeve 28. A conductive block 34 is electrically connected to the inside of the resistance winding 27. A spring 29 is sleeved on the outside of the sleeve 28. A viewing window 14 is provided on the outside of the cylinder 1.

[0032] The working principle of the above technical solution is as follows:

[0033] In use, the user first connects the inlet pipe 7 and the outlet pipe 12 and installs them in the pipe where the filtration component is needed. At the same time, the user closes valve 29 and opens valve 16, so that the water to be filtered is introduced into the cylinder 1 through the inlet pipe 7. Under the spiral guidance between the threaded plate 19 and the inner sleeve 24, the water flows into the bottom of the inner sleeve 24 and enters the inner side of the inner sleeve 24 through the inlet hole 21. Then, under the water pressure, the water flows through the inclined filter plate 23 and the metal filter screen 20 to reduce the clogging of large particles. Then, the water flows through the multi-layer filtration of the SST filter membrane module 31 and finally enters the next component through the inner cylinder 15 and the outlet pipe 12. The overall filtration efficiency is high, and it can be installed upside down or square according to needs for easy filtration.

[0034] In another implementation scheme, such as Figures 1-3 As shown, the inlet holes 21 are arranged in a circumferential linear uniform pattern inside the inner sleeve 24, and one end of the inlet pipe 7 is connected to the top of the threaded plate 19.

[0035] The inlet hole 21 can form a large-diameter filter screen, which can block large particles of debris, stones and other impurities while dispersing the spiral water flow. The position of the inlet pipe 7 makes it easy to guide the water flow into the inside of the threaded plate 19. The threaded plate 19 can apply a spiral force to the water flow, which can facilitate the stirring and rotation of impurities and prevent them from accumulating in one place.

[0036] In another implementation scheme, such as Figure 1 and Figure 2 As shown, the fastening bolts 11 move through the top cover 10 and the flange plate 2 5 and extend to the bottom of the flange plate 2 5. The fastening bolts 11 are evenly distributed in a circle on the outside of the top cover 10 and the flange plate 2 5.

[0037] The fastening bolts 11 fix the top cover 10 to the position of the flange plate 25, which facilitates the limiting of the inner cylinder 15 and makes it easy to carry out stable operation and use.

[0038] In another implementation scheme, such as Figures 1-3 As shown, the base plate 2 has an installation hole inside, the flange plate 4 is fixedly installed inside by bolts, a sealing ring is provided at the connection between the cylinder 1 and the spherical shell 3, and the specifications and dimensions of the bottom of the inlet hole 21 are compatible with the specifications and dimensions of the spherical shell 3.

[0039] When the base plate 2 is installed as a whole in the filter assembly or other structures, the bottom can be fixed by inserting bolts into the base plate 2. It can be installed upside down or upright for assistance, which helps to increase the structural strength. The cylinder 1 and the spherical shell 3 can be fixed by the flange plate 4, which helps to increase the sealing of the connection and the overall performance is good.

[0040] In another implementation scheme, such as Figures 1-3 As shown, flange plates are installed at one end of the inlet pipe 7, outlet pipe 8, outlet pipe 12, and U-pipe 13.

[0041] When disassembly, cleaning, and maintenance are required, first connect U-tube 13 to one end of the next outlet pipe 8 via flange plate and bolt assembly. Then, close valve 6 and open valve 9 inside U-tube 13 to guide the water flow around the inside of cylinder 1 and into the next filter assembly. Afterward, insert the bolts inside the top cover 10 and flange plate 4 respectively, remove the inner cylinder 15 from the inside of cylinder 1, and remove the spherical shell 3. Clean the large particles of impurities remaining inside the spherical shell 3 and cylinder 1, and rotate the inclined filter plate 23 to remove the inclined filter plate 23 and metal filter screen 20. This allows the mounting ring 30 and SST filter membrane assembly 31 to be removed for cleaning and maintenance, increasing the convenience of disassembly and assembly without affecting the operation of other filter components. This facilitates maintenance and provides good performance.

[0042] In another implementation scheme, such as Figure 3 and Figure 5 As shown, the mounting rings 30 are arranged linearly and uniformly inside the inner sleeve 24, and sealing rings are stacked on opposite sides of the mounting rings 30.

[0043] The mounting ring 30 is kept in a stable position by the support rod 26 and the inner cylinder 15. The multiple sets are designed to increase the filtration effect. The overall structure has a good performance and facilitates the flow of water through the inner side of the mounting ring 30 and the SST filter membrane module 31.

[0044] In another implementation scheme, such as Figure 3 and Figure 4 As shown, the support column 18 is evenly distributed in a circle around the support rod 26 at the bottom of the partition plate 17. The partition plate 17 is fixedly installed inside the inner cylinder 15. The outer diameter of the support rod 26 is matched with the inner diameter of the mounting ring 30. A soft pad is fixedly installed at the bottom of the support column 18.

[0045] The bottom end of the support column 18 contacts the outer ring of the uppermost mounting ring 30, which facilitates the stabilization of the structural position, increases the stability of the torque, reduces deflection, and increases the stability between structures. The support rod 26 is sleeved on the inner side of the mounting ring 30, which facilitates the stabilization of the position, increases the overall limit and usability, and has a good performance.

[0046] In another implementation scheme, such as Figures 3-5 As shown, the conductive block 34 is fixedly installed on the top of the support rod 26. The specifications and dimensions of the support rod 26 are compatible with those of the sleeve 28. The top of the spring 29 is fixedly installed on the top of the inner cavity of the inner cylinder 15, and the bottom of the spring 29 is fixedly installed on the top of the ring plate 25.

[0047] With the piston 32 in place, during use, water pressure is guided by the inclined filter plate 23 and the metal filter screen 20 to the bottom and inner side of the piston 32. The pressure is transmitted upward through the support rod 26 sliding limit on the inner side of the mounting ring 30. Then, the flange plate 25 compresses the spring 29, causing the conductive block 34 to slide inside the resistance winding 27, forming a sliding rheostat. The current and voltage changes of this section can be measured by connecting the conductive block 34 and the resistance winding 27 with wires. Therefore, the internal water pressure can be indirectly determined, increasing the ability to detect different filter components during use, resulting in good overall performance.

[0048] The working principle and usage process of this invention are as follows: In use, the user first connects the inlet pipe 7 and the outlet pipe 12 within the pipe requiring the filtration assembly. Simultaneously, valve 29 is closed and valve 16 is opened, allowing the water to be filtered to flow from the inlet pipe 7 into the cylinder 1. Under the spiral guidance between the threaded plate 19 and the inner sleeve 24, the water flows into the bottom of the inner sleeve 24 and then into the inner side of the inner sleeve 24 through the inlet hole 21. Subsequently, under water pressure, the water flows through the inclined filter plate 23 and the metal filter screen 20 to reduce large particles. The water is initially blocked by particulate matter, then filtered through the multi-layered SST filter membrane module 31, and finally guided by the inner cylinder 15 and the outlet pipe 12 into the next component. The overall filtration efficiency is high, and it can be installed inverted or upright as needed for easy filtration. When disassembly, cleaning, and maintenance are required, firstly, connect the U-tube 13 to one end of the next outlet pipe 8 using a flange plate and bolt assembly. Then, close valve 6 and open valve 9 inside the U-tube 13 to guide the water flow around the inside of the cylinder 1 and into the next filter component. The bolts inside the top cover 10 and flange plate 4 can be inserted separately to remove the inner cylinder 15 from the cylinder 1. The spherical shell 3 can then be removed to clean any remaining large particles of impurities inside the spherical shell 3 and cylinder 1. The inclined filter plate 23 and metal filter screen 20 can then be removed, allowing the mounting ring 30 and SST filter membrane assembly 31 to be removed for cleaning and maintenance. This increases the ease of disassembly and assembly without affecting the operation of other filter components, facilitating maintenance and improving performance. Furthermore, the piston 32, during operation, allows water pressure to pass through the inclined filter plate 23 and... The flow from the metal filter screen 20 enters the bottom and inner side of the piston 32. The pressure is transmitted upward through the support rod 26, which slides and limits the movement inside the mounting ring 30. Then, the flange plate 25 compresses the spring 29, causing the conductive block 34 to slide inside the resistance winding 27, forming a sliding rheostat. The current and voltage changes in this section can be measured by connecting the conductive block 34 and the resistance winding 27 with wires. Therefore, the internal water pressure can be indirectly determined, increasing the ability to detect different filter components during use. The overall performance is good.
