Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a nanoparticle-enhanced gradient pore metal filter structure. Background Technology

[0002] Traditional filter cartridges have a simple filtration structure, mostly with a single filtration layer. When faced with fluids containing complex components, they cannot accurately intercept various impurities, resulting in poor filtration performance.

[0003] For example, in food and beverage production, incomplete removal of microorganisms and particulate impurities may affect product quality and safety; in industrial wastewater treatment, the inability to fully filter pollutants makes it difficult to meet discharge standards; ordinary filter materials have limited ability to intercept microparticles and lack antibacterial properties, allowing microorganisms to easily grow and multiply on the filter surface, causing not only secondary pollution but also clogging the filter and significantly shortening its lifespan. This results in low filtration efficiency and rapid accumulation of impurities, leading to filter blockage and increased maintenance costs and replacement frequency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of traditional filter cartridges, which have simple filtration structures and contain only a single filtration layer, making it difficult to accurately intercept various impurities in complex fluids, and the filter cartridge materials have poor interception ability for small particles and lack antibacterial properties, resulting in poor filtration effect. This utility model provides a nanoparticle-enhanced gradient pore metal filter cartridge structure.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A nanoparticle-reinforced gradient pore metal filter element structure includes a central rod, a supporting skeleton sleeved on the outer side of the central rod, and a fine filter assembly, a transition assembly, and a coarse filter assembly sleeved around the outer periphery of the central rod. A top cover ring is sleeved on the top of each of the fine filter assembly, the transition assembly, and the coarse filter assembly, and a bottom cover plate is sleeved on the bottom of each of the fine filter assembly, the transition assembly, and the coarse filter assembly. The outer end of the supporting skeleton penetrates the sidewalls of the fine filter assembly, the transition assembly, and the coarse filter assembly. The pore inner diameter on the sidewalls of the fine filter assembly, the transition assembly, and the coarse filter assembly increases sequentially. The fine filter assembly is made of a nickel-based alloy and nano-Ag particles. The transition assembly includes an intermediate substrate, a transition hole, and a transition channel. The transition hole is located on the sidewall of the intermediate substrate, and the outer end of the transition channel is located inside the transition hole on the inner sidewall of the intermediate substrate.

[0007] Furthermore, the fine filtration assembly includes an inner substrate and fine filtration holes. The fine filtration holes are disposed on the sidewall of the inner substrate, and the fluid is filtered with high precision through the fine filtration holes on the sidewall to intercept impurities such as tiny particles and microorganisms.

[0008] Furthermore, the sidewall of the supporting skeleton penetrates the sidewall of the intermediate substrate. Both the intermediate substrate and the transition channel are made of titanium alloy and have a nano-TiO coating on their surface. The nano-TiO coating enhances the surface's hydrophilicity and anti-fouling ability, preventing impurities from adhering and accumulating in the channel.

[0009] Furthermore, the coarse filter assembly includes an outer substrate and coarse filter holes. The coarse filter holes are disposed on the sidewall of the outer substrate. The outer substrate is made of stainless steel and nano-SiC to initially intercept large particulate impurities in the fluid. The nano-tungsten carbide particles enhance the wear resistance and impact resistance of the outer substrate.

[0010] Furthermore, the central rod is made of stainless steel, and the support frame is made of titanium alloy, providing stable central support for the entire filter element.

[0011] Furthermore, the support frame is fixed to the fine filter assembly, the transition assembly, and the coarse filter assembly by welding, providing additional support for each assembly and enhancing the overall structural strength of the filter element.

[0012] Furthermore, nano-tungsten carbide particles are uniformly added inside the outer substrate, which enhances the wear resistance and impact resistance of the outer substrate and ensures the stability of the coarse filter assembly when intercepting large particulate impurities.

[0013] Furthermore, a limiting nut is sleeved on the top of the central rod, and the bottom side of the limiting nut is movably connected to the top axis of the support frame, which plays a limiting role for the support frame and the entire filter element structure, preventing the components from shifting in the axial direction.

[0014] Compared with the prior art, this utility model provides a nanoparticle-enhanced gradient pore metal filter element structure, which has the following beneficial effects:

[0015] This nanoparticle-enhanced gradient pore metal filter element structure achieves graded filtration of impurities of different particle sizes through the layered interlocking of fine filtration components, transition components, and coarse filtration components. The fine filtration components are made of nickel-based alloy and nano-Ag particles, which not only significantly improve the interception capability of small particles, but also endow it with antibacterial properties, effectively inhibiting the growth of microorganisms and ensuring the purity and safety of the filtered fluid. The intermediate matrix and transition channel of the transition component work together to effectively intercept medium-sized impurities and optimize the fluid transition effect. The gradient pore design allows the fluid to be filtered gradually as it passes through the filter element, which not only improves filtration efficiency, but also reduces the risk of clogging and extends the service life of the filter element.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example:

[0024] like Figures 1-6 As shown, a nanoparticle-reinforced gradient pore metal filter element structure includes a central rod 1, a support frame 2 sleeved on the outer side of the central rod 1, a fine filter assembly 4, a transition assembly 5, and a coarse filter assembly 6 sleeved around the outer periphery of the central rod 1, an upper cover ring 3 sleeved on the top of the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6, and a bottom cover plate 7 sleeved on the bottom of the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6. The outer end of the support frame 2 penetrates the sidewalls of the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6. The pore inner diameters on the sidewalls of the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6 increase sequentially. A limiting nut 8 is sleeved on the top of the central rod 1, and the bottom side of the limiting nut 8 is movably connected to the top axis of the support frame 2. The support frame 2 is fixed to the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6 by welding.

[0025] Among them, the central rod 1 is made of 316L stainless steel and the support frame 2 is made of titanium alloy, which provides stable central support for the entire filter element and ensures that each component will not be displaced or deformed due to fluid pressure during the filtration process.

[0026] like Figure 6 As shown, the fine filtration component 4 includes an inner substrate 41 and fine filtration holes 42. The fine filtration holes 42 are disposed on the side wall of the inner substrate 41 to trap impurities such as tiny particles and microorganisms.

[0027] Among them, the fine filter component 4 is made of nickel-based alloy and nano Ag particles, which improves the filtration performance of the fine filter component 4 and also gives it certain antibacterial properties.

[0028] like Figure 3 , Figure 5 and Figure 6 As shown, the transition component 5 includes an intermediate base 51, a transition hole 52, and a transition channel 53. The transition hole 52 is located on the side wall of the intermediate base 51, and the outer end of the transition channel 53 is located inside the transition hole 52 on the inner side wall of the intermediate base 51. The side wall of the support frame 2 penetrates through the side wall of the intermediate base 51.

[0029] The intermediate substrate 51 and the transition channel 53 are both made of titanium alloy. The transition channel 53 optimizes the flow path of the fluid, effectively intercepts medium-sized impurities, and has a nano-TiO coating on its surface, which enhances the surface's hydrophilicity and anti-fouling ability, preventing impurities from adhering and accumulating in the channel.

[0030] like Figure 6 As shown, the coarse filter assembly 6 includes an outer substrate 61 and coarse filter holes 62. The coarse filter holes 62 are disposed on the side wall of the outer substrate 61. The larger coarse filter holes 62 can initially intercept large particulate impurities in the fluid.

[0031] The outer substrate 61 is made of stainless steel and 20% nano-SiC. Nano-tungsten carbide particles are uniformly added inside the outer substrate 61 to enhance its wear resistance and impact resistance, ensuring the stability of the coarse filter assembly 6 when intercepting large particulate impurities.

[0032] Working principle: such as Figures 1-6 As shown, fluid introduction: the fluid enters from the outer periphery of the filter element and first contacts the coarse filter assembly 6. The coarse filter assembly 6, which is composed of a stainless steel matrix containing 20% ​​nano SiC and an outer matrix 61 with uniformly distributed nano tungsten carbide particles inside, initially intercepts large particulate impurities in the fluid with its large coarse filter pores 62. The nano tungsten carbide particles enhance the wear resistance and impact resistance of the outer matrix 61, ensuring the stability of the coarse filter assembly 6 when intercepting large particulate impurities.

[0033] Graded filtration

[0034] Transition filtration: The fluid after coarse filtration continues to be filtered through transition component 5. The transition hole 52 on the side wall of the intermediate substrate 51 guides the fluid in. Then the fluid flows along the transition channel 53 made of titanium alloy and coated with nano TiO. The transition channel 53 optimizes the flow path of the fluid and effectively intercepts medium-sized impurities. The nano TiO coating enhances the surface's hydrophilicity and anti-fouling ability, preventing impurities from adhering and accumulating in the channel.

[0035] Fine filtration process: The fluid that has passed the intermediate filtration reaches the fine filtration component 4. The inner substrate 41, made of nickel-based alloy and nano Ag particles, performs high-precision filtration of the fluid through the fine filtration holes 42 on the side wall, intercepting impurities such as tiny particles and microorganisms. The nano Ag particles not only improve the filtration performance of the fine filtration component 4, but also endow it with certain antibacterial properties, inhibiting the growth of microorganisms and ensuring the quality of the filtered fluid.

[0036] Structural support and stability

[0037] Central support: The central rod 1, made of 316L stainless steel, provides stable central support for the entire filter element, ensuring that the components will not be displaced or deformed due to fluid pressure during the filtration process;

[0038] External support: The support frame 2, made of titanium alloy, runs through the side walls of the fine filter assembly 4, the transition assembly 5, and the coarse filter assembly 6, and is fixedly connected to them by welding. This not only provides additional support for each assembly, but also enhances the overall structural strength of the filter element, enabling it to withstand greater fluid pressure and ensuring stable operation of the filter element under different working conditions.

[0039] Sealing and Limiting

[0040] Sealing design: The top cover ring 3 and the bottom cover plate 7 are respectively fitted onto the top and bottom of the fine filter assembly 4, the transition assembly 5 and the coarse filter assembly 6 to prevent fluid leakage and ensure that the fluid can only pass through the filter element for filtration along a predetermined path.

[0041] Limiting and fixing: The limiting nut 8 at the top of the center rod 1 is movably connected to the top axis of the support frame 2, which plays a limiting role in the support frame 2 and the entire filter element structure, preventing the components from shifting in the axial direction and ensuring the stability of the filter element structure.
