Description
Technical field
The utility model relates to a kind of screen window, especially relates to a kind of embedding core pattern electrostatic dust collection window screen.
Background technology
At present, it is one of generally acknowledged effective ways that Electrostatic Absorption method is removed fine particle, and for example some anti-PM2.5 mouth mask is exactly to adopt easily to make with the special material of static, and it has the good effect of removing fine particle after testing.But this series products is owing to cleaning difficulty, majority is disposable products.
Before screen window field, had and screen window is connected to improve the way of screen window efficiency of dust collection with electrostatic generator, but still cannot overcome difficult difficulty of cleaning, electrostatic generator is comparatively expensive simultaneously, has increased cost in kind.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of embedding core pattern electrostatic dust collection window screen, and this screen window is with low cost, be easy to clean, and effectively dust removal.
A kind of embedding core pattern electrostatic dust collection window screen that the utility model provides, comprise frame, gauze, induction machine and drive motors, in described frame, gauze is set, described gauze is formed by the interlaced braiding of interconnective many filaments, the tail end of described many filaments converges bunchy in one end of screen window, is connected with in induction machine 1 or 2 discharge metal balls by stainless steel wire; Induction machine is connected by motor shaft with drive motors; Wherein: described filament is lamination layer structure, internal layer is conductive core, and skin is insulating coating.
Conductive core described in above-mentioned filament is stainless steel material; Described insulating coating is glass fiber, polypropylene or resinous material.
In the utility model, when induction machine work, produce electric charge by the mode of friction starting point, and converge in two metal ball.Because conductive core used in gauze is insulated material parcel, electric charge is not easy to escape, therefore on screen window surface uniform band like charges and become Electrostatic Absorption material, thereby can reach the effect of effective dedusting; After stopping supplying with charge inducing, due to the existence of conductive core, gauze surface is difficult for hoarding electric charge, therefore becomes again antistatic material and reach the effect of easy cleaning.In addition, the utility model also has with low cost and simply constructed advantage.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, a kind of embedding core pattern electrostatic dust collection window screen that the utility model provides, comprises frame, gauze, induction machine and drive motors.Gauze is set in frame, and gauze is formed by the interlaced braiding of interconnective many filaments, and the tail end of many filaments converges bunchy in one end of screen window, is connected with in induction machine 1 or 2 discharge metal balls by stainless steel wire; Induction machine is connected by motor shaft with drive motors; Wherein: filament is lamination layer structure, internal layer is conductive core, and skin is insulating coating.
In the utility model, adopt J2310 electrostatic induction machine as induction machine, while specifically enforcement, we do not configure Leyden jar; Wind is removed simultaneously; Drive motors 1 is connected by motor shaft with induction machine, and drive motors 1 is fixed on induction machine by fixed transverse rod 2, drive motors 1 drive and can manual adjustments induction machine in the rotation of disk 7.
In the utility model, the conductive core of each silk thread interconnects, and is connected with a stainless steel wire 11, and stainless steel wire 11 is connected in the generation of static electricity end (being discharge metal ball 10) of induction machine.Two discharge metal balls 10 can be connected with stainless steel wire 11 simultaneously, also can only use a discharge metal ball 10, another secure package.
Concrete operations of the present utility model are as follows: the rotational power by drive motors 1 as induction machine, drive drive 3 and driving wheel 4, metallic brush 6 produces charge inducing with the sheet metal friction on glass backing plate 9, collecting electrostatic charge by collecting comb 5 reaches on discharge metal ball 10, discharge metal ball 10 is connected with stainless steel wire 11, stainless steel wire 11 is connected with the conductive core of gauze, thereby makes to respond to electrostatic charge on gauze belt, realizes dedusting.In the time stopping supplying with charge inducing, the electrostatic charge on gauze surface is escaped from conductive core conduction, thereby becomes a kind of antistatic material, is difficult for absorption dust, convenient cleaning.
In order to test the efficiency of dust collection of our finished product, we are by the polyamide coating screen window being prepared into and polyethylene coating screen window sample is delivered to its overall removal efficiency to fine particle of Fudan University's Atmospheric Chemistry Spot detection and the Removal efficiency of particulate matter under different-grain diameter distributes, and obtain result as Fig. 2, Fig. 3.
Fig. 2, Fig. 3 are respectively polyamide coating layer screen window and polyethylene coating screen window is schemed by several concentration of the particle of gauze over time in affix charge inducing front and back.Measuring apparatus is 3771 type particle condensation counters, adopts normal flow 0.3 L/min, and the particle size range of measuring particle is 10 nm ~ 3 μ m, can be approximated to be the granule number of PM2.5, and adopts Real Atmosphere as test specimens gas; Additional electrostatic equipment is J2310 type induction machine, and rotating speed is 85 r/min.
Test result shows: polyamide coating screen window for the clearance of fine particle up to 85%, and the efficiency of dust collection that only needs can reach more than 80% for 9 seconds.In the situation that continuing additional charge, also can keep stable efficiency of dust collection.Stop after additional charge, because additional charge is progressively neutralized or escapes, the several concentration that detect progressively return to the actual concentration in atmosphere, because this composite material is difficult for hoarding electric charge, electrostatic charge can be escaped more quickly, make this screen window be difficult for adsorption particle thing.
For polyethylene coating screen window, there is certain barrier effect to cause several concentration to decline to some extent therefore aperture on screen window is little to particle.But only need 30s can reach 83% clearance after additional charge, and effect stability.
Further, we also by the difference particle diameter scanner (TDMA) at Fudan University's Atmospheric Chemistry center to Atmospheric particulates with carry out the particle diameter scanning of number concentration under different-grain diameter by the particle of additional charge gauze, simultaneously with the disposable active charcoal mouth mask newly sealed off as a comparison, calculate the removal efficiency under different-grain diameter, the results are shown in Figure 4.
As can be seen from Figure 4, the clearance of two kinds of screen windows particle more than 100 nm is up to more than 90%, and the effect of specific activity charcoal mouth mask is better; Below 80 nm time, because particle motion is violent, Electrostatic Absorption effect declines to some extent, even but still keep 80% removal efficiency at the granule at 30 nm places; The particle size range of 100 nm to 600 nm can be used as the high-effective dust-removing section of this screen window, and the Removal efficiency of particulate matter of this particle size range reaches more than 90%.
