Problems solved by technology

[0003] The existing filters mainly use non-woven fabric or paper to filter particle dust, activated carbon to absorb harmful odors, etc., but these materials also have many defects. For example, once activated carbon is combined with water molecules in the air, it loses the ability to effectively adsorb. capacity, non-woven or paper materials are easy to absorb water and deform or even break, and the filter cannot be cleaned effectively, so the existing filter has a short service life and poor capacity, and the filtering effect needs to be improved

Embodiment 1

[0032] Such as figure 1 As shown, a filter screen includes a filter screen frame 1 and a filter material 3 arranged in the filter screen frame 1, and the filter material 3 is a polyurethane synthetic resin filter material. The polyurethane synthetic resin filter material is foamed into a spongy filter material with pores, and the spongy filter material is arranged in the filter screen frame 1 .

[0033] The polyurethane synthetic resin filter material is directly arranged in the filter screen frame 1 to effectively filter dust, germs and even mosquitoes in the air. The polyurethane synthetic resin filter material has a large filter area and is viscous at the same time. The air passing through the filter can be fully filtered without affecting the air permeability; when dust, germs and even mosquitoes in the air pass through the filter, it will Adhering to the surface of polyurethane synthetic resin filter material, the filtering effect is good; polyurethane synthetic resin fi...

Embodiment 2

[0036] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that it also includes a support body 2 connected to the screen frame 1, and the polyurethane synthetic resin filter material is adhered to the support body 2.

[0037]The support body 2 is a linear body or a filament 22 . The diameter of the linear body or filamentary body 22 is 0.01 mm to 1 mm. The two ends of linear body or filamentary body 22 are connected to filter screen frame 11, and linear body or filamentary body 22 can be arranged in parallel, or staggered arrangement, are arranged closely in the filter screen frame 11, effectively filter the dust in the air, Germs and even mosquitoes. The diameter of the linear body or the filament 22 is 0.01 mm to 1 mm, specifically, the diameter can be set to 0.01 mm, 0.02 mm, 0.03 mm, 0.05 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm mm, 0.8mm, 1.0mm, etc., use the linear body or filament 22 with the above-mentioned diameter, s...

Embodiment 3

[0040] Such as image 3 As shown, the difference between this embodiment and Embodiment 2 is that the support body 2 includes several linear bodies or several filamentary bodies 22, and several support rods 21, and the several support rods 21 are vertically arranged on the screen frame In the plane formed by 11 , the linear body or filament 22 is wound around different support rods 21 , and the polyurethane synthetic resin filter material is arranged on the linear body or filament 22 .

[0041] Such as Figure 4 As shown, the linear bodies or filaments 22 are alternately wound around different support rods 21 to form a filter screen core layer, and the filter screen core layer is more than two layers. The linear body or filament 22 is wound irregularly or regularly on the support rod 21 to form a filter core layer, and then a second layer of filter core is formed on the first layer of filter core layer with its mesh staggered After several times in this way, a three-dimensio...

Abstract

The invention belongs to the technical field of filtering devices, and particularly relates to a filter screen. The filter screen comprises a filter screen frame and a filtering material arranged in the filter screen frame; the filtering material is a polyurethane synthetic resin filtering material. The polyurethane synthetic resin filtering material has a relatively large filtration area and viscosity at the same time; air passing the filter screen can be filtered fully without influence on air permeability; when passing the filter screen, dust, germs even mosquitoes in the air can be stuck on the surface of the polyurethane synthetic resin filtering material; the filter effect is good; the polyurethane synthetic resin filtering material can be cleaned repeatedly; the matters stuck on the surface can be cleaned with tap water or detergent; original surface viscosity can be recovered; the filter screen can be cleaned effectively; the service life is long.

Description

technical field [0001] The invention relates to the technical field of filter devices, in particular to a filter net. Background technique [0002] At present, environmental pollution is becoming more and more serious. The residues discharged in the process of daily power generation, industrial production, and automobile exhaust emissions produce a large amount of particulate matter that can enter the lungs, which directly endangers people's health; residents living in cities are exposed to air pollution. Therefore, the research and development of a filter screen that can effectively filter dust, pathogenic microorganisms and other substances in the air will play a positive role in human health. [0003] The existing filters mainly use non-woven fabric or paper to filter particle dust, activated carbon to absorb harmful odors, etc., but these materials also have many defects. For example, once activated carbon is combined with water molecules in the air, it loses the ability...
