Description

Technical Field

[0001] This utility model relates to the field of filter laminated mesh technology, and in particular to a multi-layer composite filter laminated mesh made of plastic. Background Technology

[0002] Filter laminates are widely used in modern industrial production and daily life. In the chemical industry, they are used to separate and purify chemical raw materials and products, ensuring product quality. In the environmental protection industry, they are key components of air purification and wastewater treatment equipment, helping to improve environmental quality. In the home sector, air purifiers, water purifiers, and other equipment also rely on filter laminates for air and water purification.

[0003] However, existing filter laminates still have the following problems: 1. Existing filter laminates have insufficient wear resistance. During long-term use, they frequently come into contact with impurities in the fluid and external objects, and the surface is easily worn. Once the surface is worn, it not only affects the appearance of the mesh, but also exposes the internal structure, resulting in a decrease in the filtration performance of the mesh, or even damage, shortening its service life and increasing replacement costs; 2. Existing filter laminates have a simple filtration structure and poor interception effect on fine dust, which increases the burden of subsequent processing. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model embodiment is to provide a multi-layer composite filter laminated mesh made of plastic material, which can solve the technical problems of insufficient wear resistance and poor interception effect of simple filter structure on fine dust in the prior art.

[0005] In a first aspect of this utility model, a multi-layer composite filter laminate made of plastic material is provided, comprising: a bottom support layer, a precision filter layer, a primary filter layer, and a protective layer.

[0006] The underlying support layer includes a base mesh, a first adhesive layer, and a reinforcing rib layer;

[0007] The precision filter layer includes a microporous membrane layer, a second adhesive layer, and a support framework layer;

[0008] The primary filter layer includes a coarse filter fiber mesh, an electrostatic adsorption layer, and a flow guiding mesh.

[0009] The protective layer includes a wear-resistant layer, a waterproof and breathable membrane, and a marking layer.

[0010] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0011] In this embodiment of the invention, the wear-resistant layer effectively resists friction, preventing the mesh surface from wearing down due to long-term use or contact with external objects, thus protecting the internal structure. The waterproof and breathable membrane prevents liquid penetration, preventing moisture intrusion from affecting the filtration effect, while ensuring normal gas flow. The marking layer allows operators to quickly identify information such as mesh specifications and applicable scenarios, facilitating management and replacement. When the fluid passes through the protective layer, the coarse filter fiber mesh quickly intercepts large particles of impurities, and the electrostatic adsorption layer captures fine dust. The two work together to complete the initial filtration. The flow-guiding mesh guides the fluid, ensuring its even distribution, which not only improves filtration efficiency but also reduces the pressure on the subsequent precision filtration layer and extends its service life. The fluid after primary filtration enters the precision filtration layer, where the microporous membrane layer, with its fine pore size, traps micron-sized particles, achieving high-precision filtration. The second adhesive layer firmly connects the microporous membrane layer to the supporting skeleton layer, preventing membrane deformation or damage during filtration and ensuring the stability and reliability of precision filtration. The reinforcing rib layer enhances the mesh's tensile and tear resistance, making it less prone to damage when subjected to greater pressure or tension. Attached Figure Description

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention.

[0023] Reference manual attached Figures 1 to 6 The diagram shows a structural schematic of a multi-layer composite filter laminate made of plastic material provided in an embodiment of the present invention.

[0024] The present invention provides a structure of a multi-layer composite filter laminated mesh made of plastic material, comprising: a bottom support layer 1, a precision filter layer 2, a primary filter layer 3, and a protective layer 4.

[0025] The bottom support layer 1 includes a bottom base mesh 11, a first adhesive layer 12, and a reinforcing rib layer 13;

[0026] The precision filter layer 2 includes a microporous membrane layer 21, a second adhesive layer 22, and a support framework layer 23;

[0027] The primary filter layer 3 includes a coarse filter fiber mesh 31, an electrostatic adsorption layer 32, and a flow guiding mesh 33;

[0028] The protective layer 4 includes an abrasion-resistant layer 41, a waterproof and breathable membrane 42, and a marking layer 43.

[0029] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0030] In this embodiment of the invention, the wear-resistant layer 41 effectively resists friction, preventing the mesh surface from wearing down due to long-term use or contact with external objects, thus protecting the internal structure. The waterproof and breathable membrane 42 prevents liquid penetration, preventing moisture intrusion from affecting the filtration effect, while ensuring normal gas flow. The marking layer 43 facilitates quick identification of mesh specifications, applicable scenarios, and other information by operators, making management and replacement convenient. When fluid passes through the protective layer 4, the coarse filter fiber mesh 31 quickly intercepts large particles of impurities, and the electrostatic adsorption layer 32 captures fine dust particles. The two work together to complete preliminary filtration. The flow guiding mesh 33... The fluid is guided to distribute it evenly, which not only improves the filtration efficiency but also reduces the pressure on the subsequent precision filter layer 2 and extends its service life. The fluid that has passed the primary filtration enters the precision filter layer 2. The microporous membrane layer 21, with its fine pore size, traps micron-sized particles to achieve high-precision filtration. The second adhesive layer 22 firmly connects the microporous membrane layer 21 to the support skeleton layer 23, preventing the membrane from deforming or breaking during the filtration process and ensuring the stability and reliability of the precision filtration. The reinforcing rib layer 13 enhances the tensile and tear resistance of the mesh, making it less prone to damage when subjected to greater pressure or tension.

[0031] In one possible implementation, the first adhesive layer 12 covers the upper surface of the base mesh 11, and the reinforcing rib layer 13 is attached to the upper surface of the first adhesive layer 12.

[0032] In this embodiment of the utility model, the reinforcing rib layer 13 is bonded to the bottom base mesh 11 through the first adhesive layer 12, which can evenly distribute the pressure and tension on the mesh to the entire bottom support layer 1, effectively avoiding the damage to the bottom base mesh 11 caused by stress concentration, and enhancing the load-bearing capacity of the mesh under complex working conditions.

[0033] In one possible implementation, the bottom base mesh 11 is a woven structure, the first adhesive layer 12 is a thermoplastic resin layer, and the reinforcing rib layer 13 is a mesh structure.

[0034] In this embodiment of the invention, the bottom base mesh 11 of the woven structure has three-dimensional interlaced pores. The first adhesive layer 12 made of thermoplastic resin can fully penetrate into the pores of the base mesh in the molten state. After cooling, it forms a mechanical interlocking structure. The mesh-like reinforcing rib layer 13 forms multi-point anchoring with the warp and weft nodes of the woven base mesh, further enhancing the interlayer bonding force.

[0035] In one possible implementation, the microporous membrane layer 21 is attached to the upper surface of the reinforcing rib layer 13, the second adhesive layer 22 covers the upper surface of the microporous membrane layer 21, and the support skeleton layer 23 is connected to the upper surface of the second adhesive layer 22.

[0036] In this embodiment of the present invention, the microporous membrane layer 21 is directly attached to the upper surface of the mesh-like reinforcing rib layer 13. The mesh structure of the reinforcing rib layer 13 provides uniform support for the microporous membrane, so that the pressure borne by the microporous membrane during the filtration process can be effectively dispersed, avoiding local stress concentration that could lead to membrane pore deformation or damage, and ensuring that the microporous membrane layer 21 always maintains stable filtration accuracy.

[0037] In one possible implementation, the microporous membrane layer 21 is a polytetrafluoroethylene membrane, the second adhesive layer 22 is an epoxy resin layer, and the support skeleton layer 23 is a rigid plastic skeleton.

[0038] In this embodiment of the invention, the support frame layer 23 composed of rigid plastic skeleton has good rigidity and compressive strength, which can provide reliable support for the microporous membrane layer 21. During high-pressure filtration, it can effectively prevent the microporous membrane layer 21 from collapsing or deforming due to force, maintain the normal shape of the micropores of the microporous membrane layer 21, and ensure that the filtration efficiency does not decrease.

[0039] In one possible implementation, the coarse filter fiber mesh 31 is connected to the upper surface of the support skeleton layer 23, the electrostatic adsorption layer 32 is laid on the upper surface of the coarse filter fiber mesh 31, and the flow guiding mesh 33 is attached to the upper surface of the electrostatic adsorption layer 32.

[0040] In this embodiment of the utility model, the coarse filter fiber mesh 31 is connected to the support skeleton layer 23, which first intercepts large particulate impurities. The electrostatic adsorption layer 32 is laid on the coarse filter fiber mesh 31, which can capture the tiny dust and particles remaining after coarse filtration, thereby achieving graded filtration. The flow guiding mesh 33 is attached to the surface of the electrostatic adsorption layer 32, which guides the fluid to pass through each layer evenly, reduces filtration dead angles, and improves the overall filtration efficiency.

[0041] In one possible implementation, the coarse filter fiber mesh 31 is a polyester fiber woven mesh, the electrostatic adsorption layer 32 is a charged fiber layer, and the flow guiding mesh 33 is a polypropylene mesh.

[0042] In this embodiment of the invention, the coarse filter fiber mesh 31 woven from polyester fiber has excellent chemical corrosion resistance and can work stably in acidic and alkaline environments. At the same time, its high strength characteristics can withstand the impact of high-flow fluid and it is not easily damaged during long-term use. After capturing dust particles, the electrostatic adsorption layer 32 made of charged fiber material can alleviate the impact of particles and reduce charge loss by its own flexibility, ensuring that the electrostatic adsorption effect is long-lasting and stable. The flow guiding mesh 33 composed of polypropylene mesh has stable chemical properties, strong anti-aging ability, and is not easily deformed during long-term use, and can continuously play a uniform flow guiding role.

[0043] In one possible implementation, the abrasion-resistant layer 41 is attached to the upper surface of the flow-guiding mesh 33, the waterproof and breathable membrane 42 is adhered to the upper surface of the abrasion-resistant layer 41, and the marking layer 43 is attached to the upper surface of the waterproof and breathable membrane 42.

[0044] In this embodiment of the utility model, the wear-resistant layer 41 is directly connected to the flow guide mesh 33. The high-strength material effectively resists the scouring and wear of particles in the fluid, thereby improving the wear resistance of the surface of the primary filter layer 3. Even in fluid environments with high sand content, it can protect the lower structure from mechanical damage and extend the service life of the entire filter laminate mesh.

[0045] In one possible implementation, the wear-resistant layer 41 is a polyurethane layer, the waterproof and breathable membrane 42 is an ethylene-vinyl acetate copolymer membrane, and the marking layer 43 is a polycarbonate layer.

[0046] In this embodiment of the invention, the wear-resistant layer 41 made of polyurethane material has extremely high hardness and toughness, which can effectively resist the high-speed scouring of sharp particles such as sand and metal shavings in the fluid.
