The invention utilizes a semipermeable membrane for filtration, the semipermeable membrane is a membrane only allowing certain molecules and ions to diffuse in and out, generally speaking, the semipermeable membrane only allows ions and small molecular substances to pass through, but biomacromolecule substances cannot freely pass through the semipermeable membrane, because the size of pores of the semipermeable membrane is larger than that of the ions and the small molecules, but smaller than biomacromolecules such as protein, starch and the like, such as parchment paper, cellophane and the like, belonging to the semipermeable membrane, but the existing filter cloth still has the problems of less filtration times, incomplete filtration and easy damage.
Therefore, it is necessary to invent an improved nano composite filter cloth.
Disclosure of Invention
In order to solve the technical problems, the invention provides an improved nano composite filter cloth to solve the problems that the conventional filter cloth still has less filtration times, incomplete filtration and easy damage. An improved nanocomposite filter cloth, comprising a screen support layer, a semi-permeable filter layer, a primary protective filter layer, a cushion, a secondary reverse osmosis layer, a confluent layer and a guiding guide contact, wherein: the semi-permeable filtering layer is arranged on the upper surface of the filtering screen supporting layer through filaments and resin adhesive, the primary protection filtering layer is arranged on the upper surface of the semi-permeable filtering layer through filaments and resin adhesive, and the buffer pad is adhered to the surface of the primary protection filtering layer through resin adhesive; the lower surface of the filter screen supporting layer is provided with a secondary reverse osmosis layer through filaments and resin adhesive, the confluence layer is arranged on the lower surface of the secondary reverse osmosis layer through filaments and resin adhesive, and the guide contact is adhered to the lower surface of the confluence layer through resin adhesive; the direction guide contact includes the supporter, flexible glue lag and flowing water guide way, and the flexible glue lag nestification is at the surface of supporter, and this flowing water guide way sets up the surface at the flexible glue lag.
The filter screen supporting layer is made of light and thin stainless steel metal sheets, and a plurality of hexagonal open holes which are uniformly arranged are formed in the surface of the filter screen supporting layer.
The semi-permeable filter layer and the secondary permeable layer adopt a plurality of layers of collodion semipermeable membranes, the semipermeable membranes are overlapped with each other, and the permeation direction between the semipermeable membranes is consistent.
The buffer pad adopts a plurality of cotton-flax fibers, and the cotton-flax fibers in the buffer pad incline to one side for a certain angle.
The guide contacts are fine long-strip-shaped rubber particles and are parallel to each other.
Compared with the prior art, the invention has the following beneficial effects:
1. the filter screen supporting layer is favorable for forming a plurality of stress points, prevents the semi-permeable filter layer below from being damaged when water needing to be filtered is pushed downwards by pressurizing from above, and prolongs the service life of the semi-permeable filter layer.
2. The semi-permeable filtering layer and the secondary permeable layer are arranged, so that impurities in the water to be filtered can be greatly filtered through permeation, and the impurities with the diameter larger than that of the nano permeable membrane can be prevented from continuously advancing.
3. The arrangement of the guide contact is beneficial to enabling filtered water to flow downwards according to a specified path, and the filtered water is prevented from flowing everywhere.

Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figures 1 to 3.
The invention provides an improved nano composite filter cloth, which comprises a filter screen supporting layer 1, a semi-permeable filtering layer 2, a primary protective filtering layer 3, a buffer pad 4, a secondary reverse osmosis layer 5, a confluence layer 6 and a guide contact 7, wherein the permeation direction of the semi-permeable membrane needs to be noticed in the use process, otherwise, the semi-permeable membrane can be torn under the participation of water pressure, the semi-permeable membrane is a thin membrane only allowing certain molecules and ions to diffuse in and out, generally speaking, the semi-permeable membrane only allows ions and small molecular substances to pass through, but biomacromolecule substances can not freely pass through the semi-permeable membrane, because the size of pores of the semi-permeable membrane is larger than that of the ions and the small molecules, the semi-permeable membrane is a main filtering structure of the invention, but the semi-permeable membrane is fragile, so the use of the filter screen supporting layer 1 is added, a plurality of stress points can be formed, and the semi-permeable filtering layer 2 below can, increase the service life of the semi-permeable filtering layer 2; under the action of the filter screen supporting layer 1, the semi-permeable filtering layer 2 and the secondary permeable layer 5 can bear increased pressure, impurities in the water to be filtered are greatly filtered through permeation, and the impurities with the diameter larger than that of the nano permeable membrane are prevented from continuously advancing; when water to be treated enters, the filter cloth is required to be impacted, and the filter cloth is prevented from being torn due to the fact that water flowing through the filter cloth directly impacts the filter cloth due to pressure by using the buffer pad 4; finally, the filtered water is collected through the guide of the guide contact 7, and the filtering is completed.
The technical solutions of the present invention or similar technical solutions designed by those skilled in the art based on the teachings of the technical solutions of the present invention are all within the scope of the present invention to achieve the above technical effects.
