Embodiment Construction

[0026] Such as figure 2 Shown is a schematic structural view of the low-resistance and low-maintenance ventilation purification device provided by the present invention, which has two filter material rolls 1 oppositely arranged, and the two filter material rolls 1 are respectively driven by a motor 3 through crawler belts 4 , a filter material 2 is wound between two filter material rolls 1;

[0027] Different from the prior art, there are also two rows of spacing shafts 5, one row of spacing shafts 5 is close to the air inlet side A, and the other row of spacing shafts 5 is close to the air outlet side B. The filter material 2. Reciprocate and reciprocate sequentially between the two rows of limit shafts 5 to form a "zigzag" winding path to increase the effective filtration area of ​​the filter material 2, thereby increasing the processing air volume and reducing the resistance of the device.

[0028] The present invention has two modes of operation - normal ventilation and ...

Abstract

The invention provides a low-resistance and low-maintenance ventilation purification device. The low-resistance and low-maintenance ventilation purification device comprises two filter material coilswhich are oppositely arranged, wherein the two filter material coils are respectively driven by a motor, and a filter material is wound between the two filter material coils. The low-resistance and low-maintenance ventilation purification device disclosed by the invention is further provided with two rows of interval limit shafts, one row of the limit shafts are close to the air inlet side, the other row of the limit shafts are close to the air outlet side, and the filter material is sequentially and repeatedly wound among the two rows of the limiting shafts to form a Z-shaped winding path. The low-resistance and low-maintenance ventilation purification device disclosed by the invention can increase an effective filtration area of the filter material; thus, treated air volume is improved,and device resistance is reduced.

Description

technical field [0001] The invention relates to a purification device for ventilation. Background technique [0002] In recent years, with the deterioration of air pollution in the outdoor environment and the improvement of people's attention to indoor air quality, a large number of large buildings such as shopping malls, office buildings, stadiums and rail transit platforms are facing the need to increase and improve filtration and purification measures. need. [0003] Because the ventilation and air-conditioning systems used in the above-mentioned large-scale venues have the characteristics of large quantity and large volume, the traditional technical solution of using filters for purification treatment has defects such as low degree of automation, frequent maintenance, and high labor costs required for the maintenance process. . [0004] Existing automatic roller shutter filter devices, such as figure 1 As shown, a filter material 2 is wound between two opposite filter...
