Abstract

Air filtering top cotton comprises a top cotton body and a plurality of reticular fiber meshes, wherein the reticular fiber meshes are adhered to the surface of the top cotton body and also adhered together by the aid of adhesive layers, and mesh densities of the reticular fiber meshes are different and are increased layer by layer from outside to inside. The stereoscopic air filtering top cotton is simple in structure, time-saving and labor-saving in manufacture, firm in adhesion and high in filtering precision, the technology of gradually increasing the densities is adopted, namely, the fiber densities are gradually increased along the direction of clean air so that high filtering efficiency can be achieved, dust can be stopped on the layers with different densities according to the size of the dust so that more dust is more effectively contained, and the structure of the top cotton can be washed out for reuse by means of reverse washing during use.

Description

A kind of air filtration top is cotton

Technical field

The utility model relates to a kind of airfiltering air filtration top cotton that is used for, and is used for the air handling system in workshops such as painting dressing automobiles, bio-pharmaceuticals, and various better purifying spaces, metallurgy have the air cleaning and the external coating field of requirement for height; Filter for paint spray booth and central air-conditioning are terminal specially and design, can filter out the particle that all particles that can destroy the quality of spraying paint and central air-conditioning end have quality.

Background technology

On Chinese market, this material is with fitting with gauze behind the cotton first impregnation in top, extruding unnecessary impregnating agent with pressure roller at last at present.Its shortcoming is: the energy is taken when taking a lot of work in (1); (2) because manual work is fitted, gauze is cotton bonding insecure with the top, opens easily; (3) jelly does not soak into fully, influences filter efficiency; (4) plain gauze is used on the surface, and constancy, filterability, permeability are relatively poor, have influenced the air-flow circulation of filtered air.

The utility model content

It is cotton that the purpose of the utility model provides a kind of air filtration top, addresses the above problem.

The purpose of the utility model realizes through following technical scheme.

A kind of air filtration top is cotton; Comprise cotton body in top and multilayer reticular fibre net, multilayer reticular fibre net is bonded in the top layer of the cotton body in top, also bonds together through adhesive-layer between the multi-layered web; The mesh density of multi-layered web is different, adopts from outside to inside cipher mode successively.

The described three-dimensional air filtration of the utility model top cotton knot structure is simple, manufacturing is time saving and energy saving, bonding is firm, filtering accuracy is high;

Utilize encryption technology gradually, promptly increase gradually, can reach, can it be blocked in the level of different densities, more effectively hold more dust according to dust-size than filtration efficiency toward the fibre density of pure air direction;

The mode of back flush capable of using in the use is rinsed top cotton knot structure well, reuses.

Description of drawings

According to accompanying drawing and embodiment the utility model is done further explain below.

Fig. 1 is the cotton structure chart in the utility model embodiment described air filtration top;

Fig. 2 is the structure chart of outer layer web;

Fig. 3 is the structure chart of inner layer web.

Among the figure:

1, pushes up cotton body; 2, multilayer reticular fibre net.

The specific embodiment

Extremely shown in Figure 3 like Fig. 1; A kind of air filtration top is cotton; Comprise cotton body 1 in top and multilayer reticular fibre net 2, the top layer of cotton body 1 is bonded with multilayer reticular fibre net 2 on the top, also bonds together through adhesive-layer between the multilayer reticular fibre net 2; The mesh density of multi-layered web 2 is different, adopts from outside to inside cipher mode successively.

The described a kind of three-dimensional air filtration of the utility model top is cotton, and it is simple in structure, and is time saving and energy saving, and bonding is firm, filtering accuracy is high;

Utilize and to encrypt multilayer technique gradually, promptly the fibre density toward the pure air direction increases gradually, can reach high filtration efficiency, can it be blocked in the level of different densities according to dust-size, more effectively holds more dust;

Person skilled in the art should be familiar with; The above embodiment only is the purpose that is used for explaining the utility model; And be not with the qualification of doing the utility model; As long as in the essential scope of the utility model, to the foregoing description do variation, modification all will drop in the claim scope of the utility model.

Claims

1. an air filtration top is cotton; It is characterized in that; Comprise cotton body in top and multilayer reticular fibre net, multilayer reticular fibre net is bonded in the top layer of the cotton body in top, also bonds together through adhesive-layer between the multi-layered web; The mesh density of multi-layered web is different, adopts from outside to inside cipher mode successively.
