Detailed Description

An embodiment of the window nested air filtering device of the utility model is shown in fig. 1 to fig. 4, the device comprises a closed box body 1 which is used for embedding and fixing on a wall window of a fan room, an air inlet 11 is arranged at the suspended part on the bottom plate of the box body, and the air inlet adopts a shutter air inlet or a grating air inlet structure; the part of the box body back plate close to the box top is provided with an air outlet 13 which is just opposite to and connected with the wall vent when in use, and the air outlet adopts a shutter air outlet structure; the space from the air inlet to the air outlet in the box body is a filtering air duct provided with three-stage filtering, the three-stage filtering is a first filtering layer 2, a second filtering layer 3 and a third filtering layer 4 which are sequentially arranged from bottom to top at intervals, the first filtering layer adopts a plate-type primary filter 5 to implement filtering, and the second filtering layer and the third filtering layer both adopt a plate-type intermediate filter 6 to implement filtering. During operation, outside air is sucked from the air inlet 11, and after three-stage filtration, clean air enters the machine room from the air outlet 13. This filter equipment is in the use, and primary filter and medium-effect filter all need regularly to be changed, consequently, still are equipped with the access door 12 of opening when changing the filter on the box, and the access door is opened and is established on the box front bezel, is convenient for implement the change operation like this, for the leakproofness of improvement door, is provided with sealed the pad between access door 12 and box 1.

In the three-stage filter layer, the structures of the second filter layer and the third filter layer are completely the same, the first filter layer and the second filter layer have the same structure except that the adopted filters are different, and the specific structure of the filter layer is described below by taking the second filter layer as an example.

The second filter layer comprises a base plate 7 which is horizontally arranged, the periphery of the base plate is hermetically fixed on the box body, and the upper space and the lower space of the base plate are divided into independent air chambers; the base plate 7 is provided with a filter unit which can be pulled and moved towards the direction of the access door, the filter unit comprises a middle-effect filter 6 and a drawer type supporting box 101 which is guided and slidably assembled on the base plate, the supporting box main body is of a box body structure with an open front side and a closed rear side and left and right sides, the middle-effect filter 6 is placed in the supporting box, and the size of the middle-effect filter is matched with the space in the supporting box; when the filter box works normally, the support box 101 is pressed against the box body back plate, the middle effect filter 6 is pressed against the rear side plate of the support box, the position is the normal working position of the filter, at the moment, the middle effect filter is just right opposite to the vent 105 at the bottom of the support box and the vent 72 of the base plate, the vent 72 of the base plate is right opposite to the vent 105 at the bottom of the support box, and the air flow of the air chamber below the base plate can enter the air chamber above the base plate only after passing through the middle effect filter 6 through the two vents, so that primary filtering is realized. In order to improve the sealing property of the assembly and prevent air leakage, a gasket may be additionally provided between the middle-efficiency filter 6 and the holder 101. In addition, the number of the filter units on the base plate 7 can be selected according to the required air volume, and can be one, two or three, if two or three filter units are arranged on the base plate, the left and right spacing arrangement mode is adopted, and the adopted filters are all necessarily the same.

The filter unit realizes drawing movement through the guiding sliding fit of the support box 101 and the base plate 7, and the specific structure is that a guide rail pair extending along the front and back directions of the box body is fixed on the base plate 7, the support box 101 is assembled in the middle of the guide rail pair in a sliding way and is in guiding fit with the guide rail 71, and under the guiding action of the guide rail 71, the support box 101 can be pushed and pulled to move in the front and back directions without deflection; meanwhile, because the front side of the tray 101 is open, and the left and right side plates of the tray and the middle filter 6 therein form a blocking relationship, the middle filter can be pushed and pulled in the tray and can not deflect. Therefore, when the filter is replaced, the support box 101 is pulled out, the filter 6 is pulled out from the support box, a new filter is pushed to abut against the rear side plate of the support box, and the support box is pushed to abut against the box body back plate, so that the filter and the support box can smoothly return to the working position. In addition, a drawer handle is arranged on one side of the support box facing the access door, so that the support box can be conveniently pulled out when the filter is replaced.

In order to prevent the filter unit from jumping due to overlarge wind resistance pressure during operation to cause air leakage, guide flanges 104 extending outwards are arranged on two sides of the bottom surface of the support box, a guide groove is correspondingly arranged between the guide rail 71 and the base plate 1, the guide flanges 104 are inserted into the guide groove and are in sliding fit with the guide groove, and the support box 101 cannot jump upwards due to the structure; meanwhile, in the filter unit, the filter is pressed and fixed through a pressing piece 102 detachably pressed on the top surface of the filter, the upward jumping of the filter relative to the support box is prevented, the pressing piece 102 is fixed on the support box 101, and when the filter is replaced, the part of the pressing piece pressed on the filter can be removed. In this embodiment, the pressing member 102 is a pressing sheet, one end of the pressing sheet is fixed on the support box by a screw, and the other end of the pressing sheet presses on the top surface of the filter.

In this embodiment, all be equipped with baffle 8 in the top of the filter of every grade of filter layer, just open the position to the filter on the baffle has ventilation hole 81, and baffle 8 is sealed fixed on box 1 all around, and like this, will form independent air chamber 82 between every baffle and the adjacent board in top, and in the use, atmospheric pressure, even flow can be stabilized to independent air chamber, can also the noise reduction.

In this embodiment, the access door adopts a filter to set up a corresponding access door, like this, the size of access door size as long as can take out change a filter can, the access door can be as little as possible, when opening the access door and changing the filter, can reduce unfiltered air from the access door inflow box to the at utmost.

When the air filtering device is installed, the rear part of the box body is partially embedded into a window of a wall body of a fan room, the length and width of the box body are matched with those of the window of the wall body, the box body is fixed on the wall body through expansion bolts, and a sealing gasket is installed between a back plate of the box body and the wall body.
