Description

Technical Field

[0001] This utility model relates to the field of nonwoven filter material technology, and in particular to low-resistance impregnated nonwoven filter material. Background Technology

[0002] Low-resistance impregnated nonwoven filter media is a high-performance filter material widely used in air purification, industrial dust removal, and liquid filtration. This filter media combines the structural advantages of nonwoven fabrics with improvements in impregnation technology, resulting in low resistance and high filtration efficiency.

[0003] These filter materials are typically made of polyester fiber, glass fiber, or other synthetic fibers, possessing good mechanical strength and air permeability. For example, the prior art, Chinese Patent Publication No. "CN211542705U", provides a low-resistance meltblown nonwoven filter material, comprising a nonwoven layer and a meltblown fiber layer, with the meltblown fiber layer covering the bottom of the nonwoven layer. The nonwoven layer consists of a horizontally woven fiber layer and fiber bundles perpendicular to the horizontally woven fiber layer, with the fiber bundles penetrating the horizontally woven fiber layer. The low-resistance meltblown nonwoven filter material in this application electrostatically charges the fibers of the meltblown fiber layer during the manufacturing process of meltblown PP material, making the fibers into electrostatic electrets with a diameter of 2-5μm, which cover the bottom of the nonwoven layer. This filter material containing electrostatic electrets, in addition to utilizing the filtration mechanism of traditional air filter materials, also utilizes the Coulomb force of charged fibers to capture particles, thus exhibiting high dust holding capacity, high efficiency, and low resistance.

[0004] Currently, most non-woven filter media are single-layer structures. With prolonged use, the filter media is easily damaged due to material wear and external forces. Therefore, it is necessary to further increase the wear resistance of the filter media and add multi-layer designs to improve the filtration stability of the filter media for long-term use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-5 The low-resistance impregnated nonwoven filter material includes a base filter screen 1, a base filter screen 2 on one side of the base filter screen 1, an odor removal filter screen 3 on the other side of the base filter screen 2, and an outer protective filter screen 4 on the other side of the odor removal filter screen 3. The base filter screen 1 is bonded and fixed to the base filter screen 2 along its edge with resin adhesive. The other side of the base filter screen 2 is bonded and fixed to the odor removal filter screen 3 along its edge. The other side of the odor removal filter screen 3 is bonded and fixed to the outer protective filter screen 4 along its edge.

[0029] Both the surface of base filter screen 1 and the surface of base filter screen 2 are provided with pleats.

[0030] The base filter 1 includes a fiber layer 10 and a fiber layer 11, which are arranged in an interlaced pattern. The base filter 2 has the same composition as the base filter 1.

[0031] Fiber layer 10 is composed of an impregnation layer 1001 and an interlayer 1002, with the impregnation layer 1001 covering the surface of the interlayer 1002. Fiber layer 11 has the same composition as fiber layer 10.

[0032] It should be further noted that the odor removal filter 3 is made of activated carbon fiber material. Activated carbon fiber has an extremely high specific surface area, which can provide a large number of adsorption sites, improve adsorption efficiency and capacity. Activated carbon fiber has good adsorption performance for organic matter, heavy metal ions, gas molecules, etc., and is suitable for applications in air purification, water treatment, waste gas treatment and other fields. Because the pore size of activated carbon fiber is uniform and has good connectivity, the diffusion resistance during the adsorption process is small and the adsorption speed is fast, making it suitable for application scenarios that require rapid response.

[0033] It should be further noted that the outer filter screen 4 is made of glass fiber material. Glass fiber can maintain stable performance at high temperatures, making it suitable for applications in high-temperature environments. It has high tensile and compressive strength, can withstand large loads and stresses, and is suitable for reinforcing composite materials and structural components. It has good corrosion resistance to most acids, alkalis and salts, making it suitable for applications in corrosive environments such as chemical, marine, and sewage treatment industries. Glass fiber has a low density, which can reduce the weight of the structure.

[0034] It should be further noted that the impregnation layer 1001 is made of a resin impregnating agent material, which mainly comprises:

[0035] Epoxy resin has good mechanical strength, chemical resistance and electrical insulation properties, and is often used in electronic packaging, composite materials and other fields.

[0036] Polyester resin: It has good corrosion resistance and mechanical strength, and is often used in ships, pipelines, storage tanks and other fields;

[0037] Phenolic resins have good heat resistance and electrical insulation properties, and are often used in electronic components, insulating materials and other fields.

[0038] It should be further noted that the interlayer 1002 is made of polyester fiber material. Polyester fiber has high tensile strength and tear resistance, can withstand large loads and stresses, has good wear resistance, can maintain a long service life under friction and wear conditions, has good resistance to most acids, alkalis and detergents, and has good heat resistance, can maintain stable performance at high temperatures.

[0039] It should be further explained that an anti-tension rope 21 is provided between the base filter 1 and the base filter 2. The two ends of the anti-tension rope 21 are sewn and fixed to the inward side of the base filter 1. Several connecting blocks 22 are distributed on the surface of the anti-tension rope 21. The surfaces of the base filter 1 and the base filter 2 are respectively bonded and fixed to the corresponding connecting blocks 22 with resin adhesive. By adding the anti-tension rope 21 structure between the base filter 1 and the base filter 22, and fixing it to the corresponding base filter 1 and the base filter 22 through the connecting blocks 22 on the anti-tension rope 21, the overall connection stability of the base filter 1 and the base filter 22 can be improved.

[0040] It should be further noted that the tensile rope 21 is made of nylon rope material, which has good abrasion resistance and can maintain a long service life under friction and wear conditions. It has high tensile strength and can withstand large loads and stresses. Nylon rope is relatively soft, easy to bend and knot, convenient to operate and use, and has good corrosion resistance to most acids, alkalis and salts. It is suitable for applications in humid and corrosive environments. It is relatively light, easy to carry and transport, and suitable for application scenarios where weight reduction is required.

[0041] It should be further noted that the connecting block 22 is made of rubber material. Rubber material has good wear resistance and can maintain a long service life under friction and wear conditions. Different types of rubber materials have different degrees of tolerance to various chemicals and are suitable for corrosion protection and sealing applications in industries such as chemical, pharmaceutical, and food. Rubber material has excellent elasticity and recovery ability and can quickly return to its original shape after being compressed or deformed. Rubber material can maintain stable performance under extreme temperature conditions and is suitable for sealing and insulation in low-temperature environments as well as heat-resistant applications in high-temperature environments.

[0042] Working method: By setting up a combination of base layer filter 1 and base layer filter 2, a double-layer structure can be set for the non-woven fabric core filter material. This not only improves the stability of filtration, but also improves the durability of the filter material. An odor-removing filter 3 made of activated carbon fiber material is added to the outward side of the base layer filter 2 to assist in the treatment of odors when filtering dust. Furthermore, an outer protective filter 4 made of glass fiber material is added to the outside of the odor-removing filter 3 to provide wear-resistant, scratch-resistant and puncture-resistant protection for the non-woven fabric filter material structure.

[0043] Both the base filter 1 and the base filter 2 are staggered with fiber layers 10 and 11, which can ensure air circulation while filtering dust. Both fiber layers 10 and 11 are composed of interlayer 1002 and impregnation layer 1001, which can improve the acid and alkali resistance, wear resistance and high temperature resistance of fiber layers 10 and 11. An anti-tensile rope 21 structure is added between the base filter 1 and the base filter 22, and the connecting blocks 22 on the anti-tensile rope 21 are fixed to the corresponding base filter 1 and base filter 22 respectively, which can improve the overall connection stability of the base filter 1 and base filter 22.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
