Description
Technical Field
The utility model relates to a self-cleaning formula new trend device of filter screen.
Background
The fresh air system mainly blocks or filters particles in outside air through a filter screen with a fine aperture, including pollen, insects and particles thereof, for example, the publication No. CN205037456U discloses a fresh air and air purification dual-purpose system, which is provided with a dust screen with a simple filtering function, a detachable electronic dehumidification filter screen and a dust removal deodorization filter screen which can be cleaned repeatedly; however, as time goes on, the particles block the filter screens, so that the air suction resistance of the fresh air system is increased, and the air exchange capacity of the fresh air system is reduced. Although the filter screen can be taken out for manual cleaning or replacement by adopting a detachable and cleanable mode, the labor cost is increased, and the filter screen is easy to damage.
Most of the prior art screens are made of polymer or non-woven fabrics, and due to the insulation, the particles (generally, insulators) in motion contact with the screens to rub to generate static electricity, and the static electricity is adsorbed on the screens under the action of the static electricity. This adsorption makes post-cleaning difficult due to its strong adsorption force.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is overcome the defect of the clean difficulty of filter screen of fresh air system among the prior art, a self-cleaning formula new trend device of filter screen is provided.
In order to solve the technical problem, the utility model provides a following technical scheme:
a filter screen self-cleaning type fresh air device comprises a ventilation pipe and a fresh air introducing fan, wherein both an air inlet and an air outlet of the ventilation pipe are provided with protective nets, and a coarse filter screen, a fine filter screen and a cleaning fan are sequentially arranged between the air inlet and the fresh air introducing fan;
the protective net is a metal net with the aperture of 1-10 mm, and the coarse filter screen is a metal net or a plastic net with the aperture of 200-500 microns; the peripheral surfaces of the coarse filter screen and the fine filter screen are respectively attached to the inner wall of the ventilation pipe;
the pore size of the fine filter screen is 5-100 microns, or the glass fiber is added with a plastic net, and a layer of 100-300nm thick nano self-cleaning coating is arranged on the fine filter screen.
Furthermore, the nano self-cleaning coating is a nano metal oxide coating or a porous super-hydrophobic nano coating. Nano self-cleaning coating
Further, the air volume of the cleaning fan is 500m3/h～5000m3H is used as the reference value. The cleaning fan and the fresh air introducing fan rotate in opposite directions. The cleaning fan and the fresh air introducing fan do not work simultaneously. When the fresh air device is started, the direction of air flow from the outdoor to the indoor is changed, when the fine filter screen needs to be cleaned, the air flow flows from the inside to the outside, the air volume of the cleaning fan is large during cleaning, and therefore dust on the self-cleaning layer is blown out of the fresh air device.
The utility model discloses the beneficial effect who reaches is: the utility model discloses add inside the new trend device and establish the one deck coarse strainer to be provided with the self-cleaning coating of nanometer on thin filter screen thereafter, the self-cleaning coating of nanometer makes the adhesion of thin filter screen surface dust very little, and the clean fan can be according to the big air volume fan that the size of new trend system selects to be suitable, thereby blows off the dust very easily, guarantees the cleanliness of thin filter screen. The coarse filter screen can prevent large-particle pollen, dust, mosquitoes or insects from blocking the fine filter screen, prevent large particles and the like from agglomerating on the nano self-cleaning coating of the fine filter screen to influence the self-cleaning effect, and the protective screen can prevent external mechanical impact or invasion of small animals and damage a fresh air system; finally, the times of dismantling and cleaning the fine filter screen can be greatly reduced, the filter screen can be cleaned even without dismantling the filter screen, the labor cost is saved, the service life of the filter screen is prolonged, a fresh air system is guaranteed to have good air supply quantity, and the performances of purifying air and adjusting temperature of equipment are improved.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
In the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Examples
As shown in fig. 1, a filter screen self-cleaning fresh air device comprises a ventilation pipe 1 and a fresh air introducing fan 6, wherein an air inlet protection net 2 and an air outlet protection net 7 are respectively arranged at an air inlet 11 and an air outlet 12 of the ventilation pipe 1, and a coarse filter screen 3, a fine filter screen 4 and a cleaning fan 5 are sequentially arranged between the air inlet 11 and the fresh air introducing fan 6;
the air inlet protection net 2 and the air outlet protection net 7 are metal nets with the aperture of 1-10 mm, and the coarse filter net 3 is a metal net or a plastic net with the aperture of 200-500 microns; the peripheral surfaces of the coarse filter screen 3 and the fine filter screen 4 are respectively attached to the inner wall of the ventilation pipe 1, so that impurities in the air can be effectively filtered.
The pore size of the fine filter screen is 5-100 microns, or the glass fiber is added with a plastic net, and a layer of 100-300nm thick nano self-cleaning coating is arranged on the fine filter screen. The nano self-cleaning coating is a nano metal oxide coating such as a nano silicon dioxide film or a porous super-hydrophobic nano coating such as the nano self-cleaning coating disclosed in the patent CN 104467648A.
Further, the air volume of the cleaning fan is 500m3/h～5000m3H is used as the reference value. The cleaning fan and the fresh air introducing fan rotate in opposite directions. The cleaning fan and the fresh air introducing fan do not work simultaneously. When the fresh air device is started, the direction of air flow from the outdoor to the indoor is changed, when the fine filter screen needs to be cleaned, the air flow flows from the inside to the outside, the air volume of the cleaning fan is large during cleaning, and therefore dust on the self-cleaning layer is blown out of the fresh air device.
For further proving the utility model discloses an effect sets up as follows contrast experiment:
