Description
Technical Field
[0001] This utility model relates to a filter assembly, and more particularly to a novel filter assembly. Background Technology
[0002] With the acceleration of industrialization, the application of various liquid filtration devices is becoming increasingly widespread. Filtration systems are widely used in various industrial production processes, such as chemical, pharmaceutical, and food processing. These industries require equipment that can effectively remove impurities from liquids to ensure product quality and the smooth operation of the production process. Filtration technology plays a vital role in the cleaning, purification, and separation of liquids.
[0003] Existing liquid filters typically consist of a housing, end caps, filter cartridges, and a manifold. The housing has an inlet and an outlet, each fitted with an end cap. The end caps have fluid channels that connect to the manifold, guiding the filtered liquid out. The filter cartridge usually consists of an outer filter layer and an inner manifold. The manifold collects the filtered liquid, while the outer filter layer removes impurities. One end of the manifold is closed, typically facing the inlet, while the other end is open and connects to the end cap at the outlet.

[0059] Please see Figure 1 , Figure 2 and Figure 4This application discloses a novel filter assembly in a preferred embodiment, which can be used to filter out particulate impurities of a target particle size from liquids. The filter assembly includes a housing 10, a first end cap 20, a mounting plate 30, a filter element 40, and a second end cap. The housing 10 includes a first accommodating space 110, and has a first opening 120 and a second opening 130, both of which communicate with the first accommodating space 110. The first end cap 20 covers the first opening 120 of the housing 10, and has a first flow channel 210 communicating with the first accommodating space 110. The mounting plate 30 is detachably connected to the housing 10. A fluid channel 310 is provided in the mounting plate 30 at the second opening 130, and the inlet of the fluid channel 310 is connected to the first accommodating space 110; a filter element 40 is provided in the first accommodating space 110, and the filter element 40 includes an interface 413 connected to the first accommodating space 110 for discharging filtered liquid, and the interface 413 of the filter element 40 is connected to the inlet of the fluid channel 310; a second end cap is provided at the outlet of the fluid channel 310 on the mounting plate 30, and the second end cap has a second flow channel opening connected to the outlet.
[0060] Specifically:
[0061] The housing 10 is the main outer shell of the entire filter assembly, typically made of corrosion-resistant, high-strength materials such as stainless steel or engineering plastics. The housing 10 contains a first accommodating space 110 for accommodating the filter element 40 and the fluid during the filtration process. The housing 10 has a first opening 120 and a second opening 130. The first opening 120 connects to the first end cap 20, and the second opening 130 is used for connecting the mounting plate 30. Both the first opening 120 and the second opening 130 communicate with the first accommodating space 110, allowing fluid to flow in and out of this space.
[0062] The first end cap 20 is installed at the first opening 120 of the housing 10, and its main function is to seal the housing 10 and prevent fluid leakage. The first end cap 20 has a first flow channel 210, which communicates with the first accommodating space 110 for fluid input or discharge and connects to an external pipeline. The first end cap 20 is usually made of a material with good sealing properties, which can ensure stable pressure inside the housing 10 and prevent external contaminants from entering.
[0063] The mounting plate 30 is one of the core innovations of this invention. It is detachably connected to the housing 10 and is located at the second opening 130. A fluid channel 310 is provided within the mounting plate 30, and the inlet of this channel communicates with the first accommodating space 110 within the housing 10. The design of the mounting plate 30 allows the entire filter element 40 to be replaced by replacing the mounting plate 30, without having to replace the entire filter assembly. The mounting plate 30 is typically made of lightweight, corrosion-resistant materials, facilitating disassembly and cleaning, and providing excellent sealing to prevent fluid leakage. Its disassembly and connection methods can employ threads or snap-fit mechanisms to ensure convenient and reliable operation. Furthermore, sealing gaskets can be installed on both the side of the mounting plate 30 facing the housing 10 and the side of the mounting plate 30 away from the housing 10 to fill the assembly gaps after the filter assembly is assembled, preventing filtrate leakage.
[0064] The filter element 40 is located within the first accommodating space 110 of the housing 10, and its main function is to remove impurities from the fluid. The interface 413 of the filter element 40 is connected to the inlet of the fluid channel 310, allowing the filtered liquid to be discharged into the fluid channel 310. Replacing the filter element 40 is very simple; users only need to replace the mounting plate 30 and the filter element 40 to adapt to different filtration accuracy requirements.
[0065] The second end cap is located at the outlet of the fluid channel 310 on the mounting plate 30 and has a second flow port. When fluid exits from the fluid channel 310, it is discharged through the second flow port, which is connected to an external pipeline to discharge the filtered purified water. The second end cap typically uses the same sealing design as the first end cap 20 to ensure that fluid does not leak when passing through the second end cap.
[0066] The working principle of this filter component is as follows:
[0067] Liquid flows into the first receiving space 110 through the first flow channel 210 and passes through the filter element 40. The first end cap 20 ensures that liquid enters the receiving space only through this flow channel, preventing leakage from other parts. The filter element 40 effectively removes impurities from the liquid, and the filtered liquid enters the fluid channel 310 through the interface 413 of the filter element 40. The filtered liquid flows out through the fluid channel 310 and exits from the second flow channel of the second end cap.
[0068] When adjusting the filtration accuracy, the user simply needs to remove the mounting plate 30, detach the filter element 40 and mounting plate 30 as a whole from the filter assembly, and then replace the mounting plate 30 with the one containing the filter element 40 of the target filtration accuracy. This process is much more convenient than replacing the entire filter assembly. Furthermore, the detachable connection method of the mounting plate 30 can be selected, such as threads or snap-fit, making disassembly easy and ensuring good sealing performance to prevent fluid leakage during the filtration process.
[0069] In this embodiment, due to the use of a detachable mounting plate 30, the filter element 40 can be replaced according to different filtration accuracy requirements, without the user needing to replace the entire filter. This not only reduces equipment maintenance costs but also improves equipment flexibility. The precise connection between the filter element 40 and the fluid channel 310 ensures effective filtration of the liquid during the filtration process, and the design of the fluid channel 310 ensures smooth liquid flow, improving filtration efficiency. Furthermore, by simply disassembling and replacing the filter element 40, users can easily adjust the filtration accuracy without complex equipment replacement or debugging. The detachable connection design of the mounting plate 30 makes this operation more convenient and ensures a tight seal. Moreover, the design of this invention reduces the need for equipment replacement, allowing companies to replace only the filter element 40 when facing various filtration accuracy requirements, without purchasing new filtration equipment, thereby saving costs.
[0070] Furthermore, in some embodiments, such as Figure 2 to Figure 5 As shown, the filter element 40 typically consists of a manifold 410 and a filter element 420, which work together to perform the functions of liquid filtration and collection. The manifold 410 includes a second accommodating space 411, and an interface 413 is formed on the surface of the manifold 410, communicating with the second accommodating space 411. The surface of the manifold 410 also has filter holes 412. The filter element 420 is disposed on the surface of the manifold 410, and covers the filter holes 412 to filter out impurities in the liquid entering the filter holes 412.
[0071] The manifold 410 is a core component of the filter element 40, typically made of a material with sufficient strength and corrosion resistance (such as stainless steel or engineering plastics). The manifold 410 is usually cylindrical or has other adaptable structures, featuring a second receiving space 411 for containing and guiding the filtered liquid flow. An interface 413 is provided on the surface of the manifold 410, communicating with the second receiving space 411 to discharge the filtered liquid from the manifold 410. Furthermore, filter holes 412 are provided on the surface of the manifold 410, allowing impurities in the liquid to be effectively removed as the filter layer passes through, with the filtered liquid entering the second receiving space 411 of the manifold 410.
[0072] The filter element 420 is typically made of high-efficiency filter material (such as porous metal mesh, fiber material, etc.), possessing strong filtration capabilities and able to trap particulate impurities in the liquid. The filter element 420 covers the filter holes 412 on the surface of the collector 410, ensuring that impurities in the liquid entering the filter holes 412 are filtered out. The design of the filter element 420 ensures that impurities are effectively intercepted by the filter element 420 when the liquid flows, and only clean liquid can pass through the filter holes 412 into the second receiving space 411 of the collector 410.
[0073] During the filtration process, the liquid to be filtered first enters the first accommodating space 110 through the filter inlet, and then flows through the filter element 420, which removes most of the particles within the target particle size range (the precision structure of the filter element 420 ensures that only the filtered liquid can pass through). After that, the filtered liquid enters the second accommodating space in the collector 410 through the filter hole 412, and is discharged from the filter element 40 through the interface 413 of the collector 410, so as to flow into the fluid channel 310 for further processing.
[0074] Furthermore, in some embodiments, such as Figure 2 and Figure 3 As shown, the aforementioned collector 410 and filter 420 are a collector tube and a filter disc, respectively. One end of the collector tube has the interface 413, and the other end is a closed end. A plurality of filter holes 412 are formed around the periphery of the collector tube. The filter 420 is a filter disc, and there are several filter discs, each fitted onto the outside of the collector tube. Furthermore, the filter element 40 also includes a pressing member and a clamping mechanism. The pressing member is fitted onto the outside of the collector tube, and the side of the pressing member facing the mounting plate 30 abuts against the filter disc furthest from the mounting plate 30. The clamping mechanism is located at the closed end of the collector tube, and includes a controlled-moving clamping end that abuts against the side of the pressing member away from the mounting plate 30 to apply pressure to the pressing member pointing towards the mounting plate 30.
[0075] Specifically:
[0076] A manifold is a robust, corrosion-resistant tubular assembly, typically made of stainless steel or plastic. One end of the manifold has an interface 413 connected to a liquid flow channel to guide the filtered liquid out. Several filter holes 412 are formed on the periphery of the manifold; these holes, together with the filter discs, effectively filter the liquid entering the manifold.
[0077] The filter discs consist of multiple circular discs, typically made of high-efficiency filter materials (such as fiber mesh), providing strong filtration performance. Multiple filter discs are fitted around the outside of the manifold and evenly distributed around it. The design of the filter discs not only increases the filtration area but also achieves effective filtration of impurities in the liquid through their porous structure.
[0078] The engagement of the pressing component and the clamping mechanism compresses several filter discs to form a dense filter layer around the periphery of the manifold along its axial direction. The pressing component is fitted onto the outside of the manifold and contacts the furthest filter disc on the side facing the mounting plate 30. The function of the pressing component is to apply pressure to compact the filter discs.
[0079] The pressing end contacts the side of the pressing component away from the mounting plate 30, and presses the pressing component against the mounting plate 30 by applying pressure, thereby effectively fixing the filter disc and ensuring the stability and sealing of the filter element 40.
[0080] During the filtration process, liquid enters the housing 10 through the inlet and then passes through a dense filter layer formed by multiple pressed filter discs. The filter discs trap impurities in the liquid, ensuring filtration accuracy. The liquid then flows through the filter holes 412 of the manifold into the second accommodating space 411 within the manifold, and finally exits through the interface 413 of the manifold. The cleaned liquid smoothly enters the downstream system or is discharged. The filter discs, through their porous structure, effectively screen impurities of different particle sizes, purifying the liquid. Furthermore, during this filtration process, the pressing mechanism applies pressure to each filter disc through the pressing component, causing the filter discs to form a dense filter layer that surrounds the manifold, thus filtering the liquid flowing through the filter holes 412 within the target accuracy range.
[0081] In this embodiment, the manifold, through its multiple filter holes 412, works in conjunction with the filter discs to form a highly efficient liquid filtration path, effectively removing impurities from the liquid and improving filtration accuracy. Furthermore, the design of the pressing component and clamping mechanism effectively maintains the stability of the filter discs, ensuring that each filter disc forms a dense filter layer under pressure, thus guaranteeing the filtration effect on the liquid.
[0082] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping mechanism includes a threaded post, an abutment, and an adjusting nut. The threaded post is located at the closed end of the manifold, the abutment is sleeved on the outside of the threaded post, and the end of the abutment facing the mounting plate 30 is the clamping end. The adjusting nut is threadedly connected to the threaded post, and the adjusting nut abuts against the side of the abutment away from the mounting plate 30.
[0083] Specifically:
[0084] In this embodiment, the clamping mechanism is designed with greater precision, including a threaded post, abutment, and adjusting nut. These components work together to achieve precise pressure regulation, thereby maintaining stability and sealing between the filter disc and the manifold.
[0085] The threaded post is located at the closed end of the manifold, and its outer surface is designed with threads to allow for threaded connection with the adjusting nut. The other end of the threaded post is firmly fixed to the closed end of the manifold and can be adjusted by rotating it under the action of the adjusting nut, thereby adjusting the overall pressure.
[0086] The abutment is an assembly that fits over the threaded post, located on the outside of the threaded post and abutting downward against the mounting plate 30. The side of the abutment facing the mounting plate 30 is designed as a clamping end, directly contacting the outermost edge of the filter disc, thereby providing pressure applied to the filter disc.
[0087] The adjusting nut is threadedly connected to the threaded post, and its function is to control the movement of the threaded post by adjusting its position through rotation. The adjusting nut contacts the side of the abutment member opposite to the mounting plate 30. By rotating the adjusting nut, the pressure applied to the pressing member can be precisely controlled, thereby adjusting the pressure between the filter discs and the manifold to achieve the desired tightening effect. This design ensures that each filter disc remains compressed at all times, thus guaranteeing the filtration effect.
[0088] During operation, the rotation of the adjusting nut causes the threaded column to move axially, further pushing the abutment towards the mounting plate 30. The clamping end of the abutment applies pressure to the filter disc, ensuring its stable fixation. By rotating the adjusting nut, the operator can precisely control the pressure applied to the filter disc according to different filtration requirements and pressure demands, ensuring good sealing and stability between the filter disc and the manifold, preventing liquid leakage and ensuring filtration effectiveness.
[0089] In this embodiment, due to the design of the adjusting nut and threaded post, the user can precisely control the pressure applied to the pressing component, thereby achieving precise clamping of the filter discs and ensuring the stability of the filtration effect. Furthermore, this design, through a reasonable clamping structure, ensures the tightness of the filter discs, contributing to improved efficiency and filtration accuracy of the entire filtration system and guaranteeing high-quality liquid filtration. Moreover, the pressure can be easily adjusted by rotating the adjusting nut, allowing users to quickly adjust the pressure according to different operating conditions, simplifying equipment maintenance and adjustment.
[0090] To prevent unfiltered liquid from seeping into the manifold through the gap between two adjacent filter discs, in some embodiments, the filter element 40 further includes several sealing sheets, each of which is disposed between adjacent filter discs to fill the gap between adjacent filter discs, thereby enhancing the sealing performance and filtration effect of the filter element 40.
[0091] Specifically:
[0092] The sealing strips are located between adjacent filter discs, and each sealing strip can fit tightly against the contact surface of the adjacent filter disc, filling the gap between the two discs and ensuring that unfiltered liquid cannot seep into the manifold through these gaps. The sealing strips are usually made of materials with good elasticity and sealing properties, such as rubber or polymers, which can effectively prevent liquid penetration.
[0093] During filtration, liquid enters through the filter discs on the outside of the manifold and impurities are removed by the filter layers of the discs. However, if gaps or gaps exist between adjacent filter discs, unfiltered liquid may enter the manifold through these gaps, affecting the filtration effect. Therefore, a sealing strip is designed to fill these gaps, ensuring that liquid can only enter the manifold through the filter holes 412 of the filter layer and cannot permeate through the gaps. The contact surface between the sealing strip and the adjacent filter discs fits tightly. When liquid flows through the filter discs during filtration, the sealing strip acts as an "isolation," effectively preventing the penetration of unfiltered liquid and ensuring the thoroughness of the filtration process. Moreover, due to the presence of the sealing strip, gaps between filter layers are effectively filled, avoiding leakage problems that may occur due to differences in filtration precision. Therefore, this design can adapt to higher precision filtration requirements and maintain higher filtration efficiency.
[0094] In this embodiment, the gaps between the filter discs are filled with sealing sheets, ensuring that liquid can only be filtered through the filter holes 412 of the filter layer, avoiding bypass flow of the liquid, thereby greatly improving the filtration accuracy and overall filtration effect. Furthermore, the sealing sheets can effectively prevent contamination of the filter element 40 due to gap leakage, extending the service life of the filter element 40 and reducing the frequency of equipment maintenance and replacement costs.
[0095] In other embodiments, to accommodate filtering with different target precision, such as Figure 4 to Figure 5As shown, the flow collector 410 is a flow collector tube, one end of which is the interface 413, and the other end of which is a closed end. A plurality of filter holes 412 are provided on the periphery of the flow collector tube. The filter element 420 is a filter cloth, which covers the outer periphery of the flow collector tube to cover all the filter holes 412. Furthermore, the number of fluid channels 310 opened in the mounting plate 30 is a plurality, and the number of filter elements 40 is also a plurality. The outlet interface 413 of each filter element 40 is connected to the inlet of each fluid channel 310 in a one-to-one correspondence.
[0096] Specifically, the manifold 410 is designed as a manifold tube, which works with the filter cloth and multiple fluid channels 310 to provide a more flexible and efficient filtration solution.
[0097] The manifold 410 is designed as a manifold tube, with one end being the interface 413 and the other end being a closed end. Several filter holes 412 are formed on the periphery of the manifold tube, which allow liquid to pass through and remove impurities. The closed end of the manifold tube ensures that liquid can collect within the tube and flow out smoothly. Furthermore, the number and distribution of the filter holes 412 in the manifold tube design can be adjusted as needed to adapt to different filtration precision requirements.
[0098] The filter cloth, acting as a filter element 420, covers the outer periphery of the manifold, encompassing all filter pores 412. The filter cloth's function is to filter impurities in the liquid, preventing larger particles from entering the filter pores 412 of the manifold. The material, weave density, and pore size of the filter cloth can be selected according to different filtration precision requirements, ensuring that filtration needs of varying precision can be met.
[0099] The mounting plate 30 contains several fluid channels 310, each with its inlet connected to a corresponding filter element 40 interface 413. Multiple filter elements 40 can operate in parallel, each corresponding to a different flow channel and filtration task. This design also allows users to select filter elements 40 of varying precision according to their needs, connecting them to the manifold interface 413 via the flow channels on the mounting plate 30, thus providing filtration solutions with different precision requirements.
[0100] After the liquid enters the first accommodating space 110 of the housing 10 through the inlet, it gradually submerges in each filter element 40. During this process, the liquid flows into the filter element 40 due to pressure difference, causing it to flow into the manifold. Upon entering the manifold, the liquid first passes through the filter cloth covering its surface. The filter cloth's fibrous structure effectively filters out impurities within the target particle size range, ensuring that only purified liquid flows into the manifold. Afterward, the filtered liquid flows into the manifold through the filter holes 412. The manifold's design ensures smooth flow of liquid within it, and the liquid enters the corresponding fluid channel 310 on the mounting plate 30 through the interface 413. Finally, the purified liquid flowing out of the manifold enters the flow channel at the second end cap through the fluid channel 310 on the mounting plate 30, and is ultimately discharged through this flow channel into an external pipeline.
[0101] This embodiment, through the precision filtration of the filter cloth and the design of the manifold, can flexibly adapt to impurities with different particle sizes, meeting filtration requirements of varying precision. Simultaneously, the modular design allows for adjustments to filtration precision and flow channel configuration according to actual needs. Furthermore, replacing the filter element 40 without replacing the entire filter significantly reduces maintenance costs and extends the equipment's lifespan. The modular design increases the convenience of maintenance and operation. This filtration assembly, through the flexible configuration of the filter element 40 and flow channels, can adapt to various industrial application scenarios, providing efficient filtration solutions and meeting filtration precision requirements under different operating conditions.
[0102] In summary, the filter element 40 in this embodiment and the aforementioned filter element 40 (the filter element 40 composed of a manifold and filter discs) can be replaced by directly disassembling the mounting plate 30, which makes the filter accuracy adjustment more convenient and broadens the applicability of the filter assembly proposed in this application.
[0103] When the liquid to be filtered enters the housing 10 through the inlet, the liquid directly impacts the closed end of the manifold. If the impact is too large, the manifold may deform, bend, or twist radially. Therefore, in some embodiments, such as... Figure 5 As shown, the filter element 40 also includes a constraint mechanism, which includes several positioning elements and an end plate. Each positioning element is correspondingly disposed at the closed end of each of the manifolds, and the end plate has several positioning holes, which are correspondingly fitted onto each positioning element to restrict the deformation of each manifold along its own radial direction. In addition, the end plate also has several connecting grooves for liquid flow.
[0104] In this embodiment, to prevent the liquid to be filtered from directly impacting the closed end of the manifold after entering the housing 10 through the inlet, causing radial deformation or twisting of the manifold, especially when the liquid flow rate is large or the liquid impact is strong, a constraint mechanism is designed to limit the deformation of the manifold. The constraint mechanism includes several positioning elements and end plates, and its specific structure and function are described below:
[0105] Positioning elements are installed one-to-one at the closed end of each manifold. The function of the positioning elements is to restrict the movement of the closed end of the manifold by physically contacting and engaging with the end plate.
[0106] Multiple positioning holes are provided on the end plate, each corresponding to a positioning element on the manifold. By inserting the positioning element into the positioning hole on the end plate, the positioning element and the end plate cooperate to form a stable support structure. This limits the radial deformation of the manifold and ensures that the manifold maintains its correct shape and stability under liquid impact.
[0107] Furthermore, to ensure smooth liquid flow through the constraint mechanism, several connecting slots are provided on the end plate. These slots provide channels for liquid flow, preventing obstruction as the liquid passes through the constraint mechanism. The design of the connecting slots ensures that the liquid can flow smoothly through the manifold and enter the subsequent filtration process.
[0108] This embodiment, through the cooperative structure of the positioning component and end plate, effectively prevents radial deformation or twisting of the manifold caused by liquid impact, thereby ensuring the stability of the manifold and extending the service life of the equipment. Specifically, the cooperative structure of the positioning component and end plate enhances the stability and impact resistance of the entire filter element 40, enabling it to adapt to higher liquid flow rates and impact forces, and making it suitable for more complex and higher-load working environments. Furthermore, the design of the connecting groove ensures smooth liquid flow within the constraint mechanism, preventing liquid flow resistance caused by the constraint mechanism, thereby improving the overall flow efficiency of the filter assembly.
[0109] In summary, the design of the constraint mechanism in this embodiment enables the filter assembly to better adapt to the liquid flow rate and impact force requirements under different working conditions, ensuring stable operation under high flow rates or large pressure differences, and improving the adaptability and versatility of the equipment.
[0110] To improve the applicability of the filter assembly proposed in this application, in some embodiments, the collector 410 is a collector tube, one end of which has an interface 413. The interface 413 of the collector tube communicates with the inlet of the fluid channel 310 opened on the mounting plate 30, and the collector tube is detachably connected to the mounting plate 30. The other end of the collector tube is a closed end, and a plurality of filter holes 412 are opened on the periphery of the collector tube. The number of fluid channels 310 opened in the mounting plate 30 is several. The filter assembly also includes a plurality of fillers (not shown in the figure), each filler being connected to each fluid channel 310 in a one-to-one correspondence, and the fillers are configured to block the fluid channels 310 when the fillers are placed in the fluid channels 310.
[0111] The filter assembly is configured such that when the number of filter elements 40 is one, such as Figure 2 to Figure 3 As shown: the interface 413 of the manifold is threadedly connected to the inlet of only one of the fluid channels 310, and the remaining fluid channels 310 are filled one by one by the corresponding fillers. The filter element 420 is a filter disc, and there are several filter discs, each of which is sleeved on the outside of the manifold.
[0112] The filter element 40 further includes a pressing member, a clamping mechanism, and several sealing sheets. The pressing member is sleeved on the outside of the manifold, and the side of the pressing member facing the mounting plate 30 abuts against the filter disc furthest from the mounting plate 30. The clamping mechanism is disposed at the closed end of the manifold, and includes a controllably movable clamping end that abuts against the side of the pressing member away from the mounting plate 30 to apply pressure to the pressing member pointing towards the mounting plate 30. Several sealing sheets are disposed between adjacent filter discs to fill the gaps between adjacent filter discs.
[0113] The filter assembly is configured such that when the number of filter elements 40 is a certain number, such as Figure 4 to Figure 5As shown: the interfaces 413 of each of the manifolds are threadedly connected to the inlets of each of the fluid channels 310 in a one-to-one correspondence, and the remaining fluid channels 310 are all filled by the corresponding fillers. The second flow channel is configured to communicate with the outlet of each of the fluid channels 310. The filter element 420 is a filter cloth, which covers the outer periphery of the manifold to cover all the filter holes 412. The filter element 40 also includes a constraint mechanism, which includes several positioning elements and an end plate. Each positioning element is correspondingly disposed at the closed end of each of the manifolds, and the end plate has several positioning holes, which are correspondingly fitted onto each positioning element to restrict the radial deformation of each manifold. Furthermore, the end plate also has several communicating grooves for liquid flow.
[0114] Specifically:
[0115] When there is only one filter element 40, the manifold interface 413 is threadedly connected to the inlet of the single fluid channel 310. This design allows the liquid to flow purposefully through a single fluid channel 310, ensuring high efficiency in the filtration process and control over the liquid flow. Other fluid channels 310 are sealed with packing material to prevent liquid from flowing through unused channels and avoid unnecessary flow paths.
[0116] Filter discs are fitted around the outside of the manifold, and the number of discs can be adjusted as needed. The multiple filter discs design results in a larger filtration area, providing more efficient filtration. The multiple filter discs are isolated by sealing plates, ensuring that liquid flows only through the filter holes 412, preventing liquid sideflow.
[0117] The pressing component is fitted onto the outside of the manifold, facing the mounting plate 30, to ensure that the filter discs do not shift during filtration and to stably filter the liquid. The clamping mechanism is located at the closed end of the manifold and consists of a controlled-moving clamping end. The pressure it applies keeps the pressing component stable, preventing the components from loosening due to liquid flow and ensuring the stability of the filtration process.
[0118] The sealing plate is located between adjacent filter discs and serves to fill the gaps between them, preventing liquid from flowing through these gaps and ensuring filtration accuracy.
[0119] After the liquid enters the housing 10, it flows through a dense filter layer composed of several filter discs and enters the manifold through the filter holes 412. The filtered liquid then enters the fluid channel 310 through the interface 413 and is discharged into the external pipe through the second flow channel opening. According to the design, the remaining fluid channel 310 is sealed by a filler to ensure that the liquid can only flow along a predetermined path.
[0120] When the liquid to be filtered is introduced into the housing 10, it flows through a dense filter layer composed of multiple filter discs. The filter discs remove impurities from the liquid. The filtered liquid then enters the fluid channel 310 through the manifold interface 413 and is finally discharged through the second flow port. The remaining unused fluid channels 310 are sealed with fillers to ensure that the liquid flow is not affected.
[0121] When there are multiple filter cartridges 40, the interface 413 of each manifold is threadedly connected to the inlet of each fluid channel 310 in a one-to-one correspondence. Each fluid channel 310 is connected to its corresponding manifold interface 413 to ensure that liquid can flow into the corresponding fluid channel 310. Furthermore, the second flow port is configured to communicate with the outlet of each of the fluid channels 310, so that the filtered liquid passing through any fluid channel 310 will converge and be discharged from the second flow port.
[0122] The filter cloth covers the outer periphery of the manifold to cover all the filter holes 412. The filter cloth can be selected with different filtration precision according to the characteristics of the liquid, and can adapt to a variety of filtration requirements.
[0123] The constraint mechanism includes several positioning elements and an end plate. The positioning elements are fixed to the closed end of the manifold, and the end plate has multiple positioning holes. The positioning elements are fitted into the positioning holes, restricting the radial deformation of the manifold. This design enhances the structural stability of the manifold under high-pressure fluid flow and avoids radial deformation caused by changes in liquid pressure. The end plate also has a connecting groove to ensure unobstructed liquid flow.
[0124] When the liquid to be filtered enters the housing 10, impurities in the liquid are filtered out as it passes through the filter cloth. The multi-layered structure of the filter cloth can filter particles of different sizes as needed. The filtered liquid flows into the corresponding fluid channel 310 and is finally discharged through the second flow port. The design of multiple fluid channels 310 provides greater processing capacity and can accommodate higher flow rate requirements.
[0125] In both embodiments of this invention, the detachable threaded connection between the manifold and the mounting plate 30 serves the following specific functions:
[0126] First, the threaded connection between the manifold and the mounting plate 30 makes the connection very convenient, allowing users to easily disassemble the manifold for cleaning, maintenance, or replacement of the filter element 40. Especially in environments requiring frequent maintenance, this design significantly reduces operational complexity and improves system operability.
[0127] Secondly, this detachable design allows users to replace the manifold with different sizes or types as needed. For example, when dealing with liquids requiring different flow rates or precision, users can replace the manifold without replacing the entire filter assembly. This flexibility is unattainable with traditional fixed-connection designs.
[0128] Furthermore, the detachable design facilitates maintenance and replacement, reducing equipment downtime and repair costs. It also minimizes unnecessary parts replacements, thereby lowering operating costs and improving the system's economic efficiency.
[0129] Therefore, when the number of manifolds is one, this filter assembly is suitable for scenarios requiring precise control of the liquid flow path and improved filtration accuracy. Its advantages lie in its simple and stable structure, making it particularly suitable for handling single-flow liquids, and its packing design and compression components ensure system stability and high efficiency.
[0130] When multiple manifolds are used, it is suitable for scenarios with higher flow rates and more complex filtration requirements. Through its design with multiple manifolds and filter cloths, it can handle larger liquid flow rates and allows for flexible adjustment of filtration accuracy. It is suitable for applications requiring greater adaptability.
[0131] Furthermore, both solutions enhance system stability, simplify maintenance and replacement processes, and provide flexibility through the detachable threaded connection between the manifold and the mounting plate 30, allowing users to adjust and maintain the system according to actual needs. This design improves the long-term reliability of the system and reduces operating costs, especially in applications requiring frequent maintenance or replacement of the filter element 40.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
