Problems solved by technology

The electrostatic filter plate itself will absorb a lot of dust in the process of filtering air, but how to clean the filter plate has always been a technical problem that plagues the industry; if the gap between the filter plates is large, sometimes it is convenient to clean, but The filtering effect is reduced again
Patent No. CN202893510U discloses a dust collecting board; patent No. CN202336389U also discloses a similar technology, but does not completely solve the problem

Embodiment 1

[0032] like Figure 4 Shown, embodiment one of the present invention, a kind of parallel electrostatic air filter plate, is made up of six parallel dust collecting plates 1, and dust collecting plate 1 is made of the insulating electret material 3 of metal plate 2 and its external wrapping, The polarity of the power supply connected to two adjacent dust collecting plates 1 is opposite. The dust collecting plates are rectangular and flake-shaped. Two raised supporting points 5 of the same height, the distance between the two dust collecting plates 1 is smaller than the height of the raised supporting points 5; the other side of the raised supporting points 5 on the dust collecting plate 1 corresponds to a concave positioning groove 6. In the figure, the support point 5 on one dust collecting board is combined with the recessed positioning groove 6 on the other dust collecting board, and a small piece of the metal plate 2 sticks out to connect the power supply.

specific Embodiment 2

[0035] Specific embodiment two, the dust collecting plate can be like Figure 4 The same building block connection can also be made by one-time molding of the mold, and the dust collecting plates are fixedly connected by insulating electret materials, such as Figure 5 As shown in the combination, you can add more raised support points, such as Image 6 same combination. Figure 7 is true Image 6 Further refinement of the structure, in the figure, the dust collecting plates 1 are connected by raised support points 5, the dust collecting plates 1 include metal plates 2 and insulating electret materials 3, and there are air passages 4 between the dust collecting plates. Figure 7 It does not reflect the dust-collecting plates and how they are connected to each other. In practice, there are many electrical connections. Each dust-collecting plate can be electrically connected to the outside. Of course, the one-time formed electrostatic air filter plate is best to be connected t...

specific Embodiment 3

[0036] Specific embodiment three, such as Figure 13 As shown, the electrostatic air filter plate is composed of six dust-collecting plates 1, and two adjacent dust-collecting plates have protruding parts of metal plates 2 at both ends, which are used to connect positive or negative electrodes, and the two ends are respectively There are raised supporting points 5, and combined with the concave positioning groove 6, they are combined into an organic whole; the filtered air channel is divided into multiple small filtered air channels 8 by multiple sheets, Figure 12 is a cross-sectional view of a single dust collection plate, from Figure 9 , Figure 10 , Figure 11 It can be seen that the sheet 7 can have various forms, Figure 9 It is Z-shaped, with a disconnection in the middle, and it can also be in a connected state; Figure 10 It is V-shaped; Figure 11 It is S-shaped. Of course, it can also present various other forms, such as W shape, straight shape and so on.

Abstract

The invention provides a parallel static-electric air filtering plate which is composed of more than two parallel dust collection plates, herein each dust collection plate is composed of a metal plate and an insulating electret material coating the metal plate. The polarity of power supplies connected to two adjacent dust collection plates are arranged oppositely. The dust collection plate is in a rectangular sheet-like shape, wherein an air filtering channel is formed among the dust collection plates. More than two protruded support points being equal in height are formed between two adjacent dust collection plates, wherein the distance between the two adjacent dust collection plates is less than or equal to the height of the protruded support points. The parallel static-electric air filtering plate is composed of a plurality of dust collection plates, wherein a self-supporting body is formed among the dust collection plates and even integrated moulding is available. The air filtering plate is convenient to install, detach and clean. By means of the electret material for insulating or coating the metal plates, the air filtering plate is free of high-voltage discharging and generation of large quantity of ozone under continuous high-voltage discharging. The air filtering plate also has a dampness-proof function and is improved in safety.

Description

technical field [0001] The invention relates to an electrostatic air filter plate, in particular to a parallel electrostatic air filter plate. Background technique [0002] In the air that is constantly polluted in real life, fine particles, especially particles with a particle size less than or equal to 2.5 microns (PM2.5), cause great harm to human health; in order to improve the air in the living room or in the cab of a car, There are many devices that use the adsorption function of the electrostatic filter plate to achieve clean air. The electrostatic filter plate itself will absorb a lot of dust in the process of filtering air, but how to clean the filter plate has always been a technical problem that plagues the industry; if the gap between the filter plates is large, sometimes it is convenient to clean, but The filtering effect is reduced again. The patent of authorized announcement number CN202893510U discloses a kind of dust collecting board; The patent of authori...
