Description

TECHNICAL FIELD

[0001] The utility model relates to filter material field, especially a kind of multilayer filter cloth. BACKGROUND

[0002] Filter cloth is the filter medium woven from natural fiber or synthetic fiber. Including metal net or filter screen. Mainly applied to air filtration and dust removal, dust powder, to purify air, protect environment, in smelting plant, chemical plant, sugar, dye, medicine, food and other industries. The existing composite filter cloth is poor in filtering effect after long-term use, and cannot play the filtering effect. SUMMARY

[0003] The utility model relates to filter material field, especially a kind of multilayer filter cloth.

[0004] In order to solve the above technical problems, the utility model discloses a kind of multilayer filter cloth, including first non-woven cloth layer, first water absorption layer, middle filter layer, second water absorption layer and second non-woven cloth layer, middle filter layer is set in middle layer, first water absorption layer and second water absorption layer are respectively set in the two outer layers of middle filter layer, first non-woven cloth layer is set in the outer layer of first water absorption layer, second non-woven cloth layer is set in the outer layer of second water absorption layer, the middle filter layer includes activated carbon cloth layer and melt-blown cloth layer.

[0005] In the utility model, the activated carbon cloth layer and melt-blown cloth layer are heat-pressed and shaped.

[0006] In the utility model, the first water absorption layer and the second water absorption layer are both made of spunlace cotton by heat pressing.

[0007] In the utility model, the first non-woven cloth layer and the second non-woven cloth layer are made of electrostatic cotton by heat pressing.

[0008] Beneficial effect: the multilayer filter cloth of the utility model sets the upper and lower two layers of non-woven cloth layer and water absorption layer, places middle filter layer in the middle, protects filter layer, and enhances the filtering effect of filter cloth. BRIEF DESCRIPTION OF DRAWINGS

[0009] The above and / or other aspects of the utility model will become more apparent by describing in detail the utility model with reference to the accompanying drawings and specific embodiments.

[0010] Figure 1 It is structural schematic diagram.

[0011] In the drawing, reference numerals: 1, first non-woven cloth layer, 2, first water absorption layer, 3, middle filter layer, 4, second water absorption layer, 5, second non-woven cloth layer. DETAILED DESCRIPTION

[0012] Embodiment:

[0013] As Figure 1 The embodiment provides a multi-layer filter cloth, which comprises a first non-woven fabric layer 1, a first water absorption layer 2, a middle filter layer 3, a second water absorption layer 4 and a second non-woven fabric layer 5, the middle filter layer is arranged in a middle layer, the first water absorption layer and the second water absorption layer are arranged in two outer layers of the middle filter layer respectively, the first non-woven fabric layer is arranged in an outer layer of the first water absorption layer, the second non-woven fabric layer is arranged in an outer layer of the second water absorption layer, and the middle filter layer comprises an activated carbon cloth layer and a melt-blown cloth layer. The activated carbon cloth layer and the melt-blown cloth layer are shaped through hot pressing. The first water absorption layer and the second water absorption layer are both formed through hot pressing of spunlace cotton. The first non-woven fabric layer and the second non-woven fabric layer are formed through hot pressing of electrostatic cotton.

[0014] In use, the first water absorption layer 2 and the second water absorption layer 4 adsorb water, prevent too much water from entering the middle filter layer, and play a protection role.

[0015] The utility model provides a kind of multi-layer filter cloth's thought and method, the method and approach of many for specifically realizing this technical scheme, above-mentioned only is the preferred implementation mode of the utility model, it should be pointed out, for the ordinary skilled in the art of this technology, under the premise of not departing from the principle of the utility model, still can make several improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the utility model.The components not specified in the embodiment can be realized using existing technology.
