Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to the attached drawing 1, the one-use one-standby efficient filtering fan box in the embodiment includes a box body 1, a channel for air circulation is arranged in the box body 1, an air inlet 11 is arranged at one end of the channel, an air outlet 12 is arranged at the other end of the channel, a filter 2 and an induced draft fan 3 are arranged in the ventilation duct, the filter 2 is arranged at one end, close to the air inlet 11, in the air duct, and the induced draft fan 3 is arranged at one end, close to the air outlet 12, in the duct. The draught fan 3 conveys air in the pipeline out of the air outlet 12, negative pressure is formed in the pipeline, air outside the filtering fan box enters the pipeline from the air inlet 11, then is filtered through the filter 2, pollutants in the air are removed, and the air is discharged from the air outlet 12 under the action of the draught fan 3, so that the air purifying effect is achieved.

In some embodiments, referring to fig. 1, an access door 13 is disposed on the box 1, and the filter 2 and the induced draft fan 3 disposed inside the box 1 can be taken out for maintenance or replacement through the access door 13, preferably, the access door 13 is disposed in a plurality, and positions of the access doors 13 correspond to positions of the filter 2 and the induced draft fan 3 one by one, so as to facilitate taking out the filter 2 or the induced draft fan 3 from the corresponding access door 13, or maintain or repair the filter 2 and the induced draft fan 3 directly through the access door 13.

In some embodiments, referring to fig. 1 and fig. 2, two air outlets 12 are provided, namely a first air outlet 121 and a second air outlet 122, an induced draft fan 3 is disposed at each of the first air outlet 121 and the second air outlet 122, and an edge of an air supply outlet of the induced draft fan 3 is disposed along an edge of the corresponding air outlet 12, so as to improve air supply efficiency of the induced draft fan 3. The first air outlet 121 and the air inlet 11 are located on the same horizontal plane, so that the suction force of the induced draft fan 3 of the first air outlet 12 to the air inlet 11 is maximum, and air can pass through the filter 2 conveniently. The second air outlet 122 is arranged right above the first air outlet 121, so that the structure of the fan box is compact, and the occupied area is reduced. Second air outlet 122 department is provided with draught fan 3, the draught fan 3 of second air outlet 122 department passes through the backup pad to support, and set up directly over the draught fan 3 of first air outlet 121 department, under normal operating conditions, gaseous under the effect of the draught fan 3 of first air outlet 121 department discharges through first air outlet 121, when first draught fan 3 needs to be maintained or maintain, can start the draught fan 3 of second air outlet department, make gaseous 2 backward upward flows through the filter, discharge from second air outlet 122. Therefore, when the induced draft fan of the first air outlet 121 needs to be maintained, the filtering fan box can be always in a working state. Through the arrangement of the two draught fans 3 and the two air outlets 12, the working efficiency of the filtering fan box is improved.

In some embodiments, referring to fig. 5 and fig. 6, the difference from the above embodiments is that the first air outlet 121 and the second air outlet 122 are arranged side by side, the vertical heights of the first air outlet 121 and the second air outlet 122 are the same, and the linear distances to the air inlet 11 are equal, only one air outlet 12 and the induced draft fan 3 corresponding to the air outlet are opened to supply air when in use, when one induced draft fan 3 needs to be maintained or repaired, the other induced draft fan 3 continues to operate, and the two induced draft fans 3 and the two air outlets 12 are arranged to enable the two induced draft fans 3 and the two air outlets 12 to alternately operate, so that the fan box cannot operate due to the fact that one induced draft fan 3 needs to be maintained, maintained or replaced, and further the working efficiency is improved. And through the setting of two draught fans 3, make two draught fans 3 and two air outlets 12 work in turn, can not reduce the life of draught fan 3 because of the long-time work of one of them draught fan 3. In this embodiment, the induced draft fan 3 is a centrifugal fan 31 (fig. 3) or an axial flow fan 32 (fig. 4), and any induced draft fan that can let air enter from the air inlet 11 and let air out from the air outlet 12 is suitable for the filter fan box.

In some embodiments, the filter 2 may be at least one selected from a primary filter 21 (fig. 3), a medium-efficiency filter 22 (fig. 2) and a high-efficiency filter 23 (fig. 1), and the specific specification of the filter 2 may be any one of a plate filter 2 and a bag filter 2, wherein the "primary filter 23" mainly refers to a filter for filtering dust particles of 5 μm or more; "intermediate filter 22" means a filter capable of filtering dust and suspended particles having a diameter of 1 to 5 μm; the "high efficiency filter 21" refers to a filter capable of filtering particles of 0.5 μm or less. The filter 2 is detachably connected with the box body 1, and the filter 2 can be replaced or maintained at regular intervals.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
