Abstract

A non-woven fabric primary filter screen comprises a filter frame and a filter screen in the filter frame, wherein the filter screen is folded into a wave shape, wave-shaped support screens are arranged at the upper side and the lower side corresponding to the wave-shaped filter screen, and a layer of protective screen is attached to the upper side and the lower side of each wave-shaped support screen; the wave filter screen has the advantages that the filter effect of the plane filter screen is increased, the filter efficiency is improved, the filter screen resistance is smaller, the air supply is more uniform, the performance is stable, and the filter effect is good.

Description

Non-woven fabric primary filter screen

Technical Field

The utility model belongs to the technical field of just imitate the filter core, a non-woven fabrics is just imitated filter screen is related to.

Background

It is known that various viruses and bacteria invade human beings every moment on the earth where we live, and various diseases are formed. The most common atmospheric pollution is the damage of haze, particularly serious in northern areas, when people go out to wear masks, visibility is low, and serious hairs and skins can be stained, so that skin diseases and respiratory diseases are caused.

Although the country has great control in the aspect of air in recent years, the pollution of the air can not be thoroughly cured, at the moment, the fresh air machine is matched with the filter screen, the purifying effect can be well achieved, the PM2.5 value of the air filtered out by the fresh air machine with excellent quality can reach 0, and the high efficiency of 0PM2.5 is realized. The fresh air machine is a household appliance which has certain removal capacity for solid pollutants (such as pollen, dust, bacteria-carrying particles and the like) and gaseous pollutants in indoor air, the fresh air machine is generally divided into a plurality of layers of protective filter screens, wherein a primary filter screen is an initial protective barrier of the air purifier, the air purifying capacity of the air purifier is determined, the primary filter screen is suitable for primary filtration of a fresh air system and is mainly used for filtering dust particles with the particle size of more than 5 micrometers, in the process of using the fresh air machine, the filter needs to be cleaned regularly, otherwise, the air output is reduced, and the air filtering effect is poor. The prior primary filter screen is generally planar, so that the filter screen has low use efficiency and low dust holding rate.

The air quality requirement of people cannot be met, which creates hidden danger to the body.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve prior art's problem, provide a non-woven fabrics primary efficiency filter screen, its wavy structure improves the availability factor of filter screen.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a non-woven fabrics primary efficiency filter screen, includes the filter frame, the filter screen in the filter frame, and the filter screen is folding to be the wave, corresponds the upper and lower both sides of wave filter screen and is equipped with the wave supporting network, the attached one deck protection network in both sides about the wave supporting network.

Further, the protective net is of a flat-plate stainless steel mesh structure.

Furthermore, the filter frame is an aluminum frame.

Technical scheme for prior art, just imitate the filter screen and be used for catching air dust granule and various suspended solids, the wave just imitates various dust and suspended solids of filter screen in to the air more than 5 microns and can reach 99.99%, has realized better initial protection protective screen to new fan, has further gone on further filtration more tiny pollutant to new fan and has laid good basis to filter layers such as high-efficient filter core and activated carbon plate in the new fan have been protected. The wave filter screen has the advantages that the filter effect of the plane filter screen is increased, the filter efficiency is improved, the filter screen resistance is smaller, the air supply is more uniform, the performance is stable, and the filter effect is good.
