[0019] The following is a further description of the utility model in conjunction with the drawings and embodiments. Embodiment 1
[0020] As Figures 1 to 3 , a dust collection device for cooperating with building wall construction, including a box body 2, a plurality of air inlet holes 3 are provided on the box wall of the box body 2, and an exhaust fan 1 communicating with the inner cavity of the box body 2 is provided on the top of the box body 2.
[0021] A sewage discharge bin 5 communicating with the box body 2 is provided outside the box body 2, a main shaft 10 is provided in the sewage discharge bin 5, and an auxiliary shaft 9 is provided at a position above the air inlet hole 3 in the cavity of the box body 2.
[0022] A filter screen 12 is wound around the main shaft 10 and the auxiliary shaft 9, the filter screen 12 is arranged across the air duct in the box body 2, and filters the dust passing through the air duct.
[0023] A drive motor 4 for driving the main shaft 10 or the auxiliary shaft 9 to rotate is provided on the box body 2. The drive motor 4 is a reduction motor with a gearbox. The main shaft 10 and the auxiliary shaft 9 are driven by the drive motor 4 to rotate slowly, and the filter screen 12 rotates together. The filter screen 12 is made of nylon mesh with relatively high structural strength.
[0024] A spray pipe 11 is provided at the middle position of the filter screen 12 in the sewage discharge bin 5. A group of nozzles 13 facing the lower filter screen 12 are provided on the spray pipe 11. A water supply pipe 7 extending into the box body 2 and communicating with the spray pipe 11 is provided on the box body 2.
[0025] Working principle:
[0026] The utility model has an air duct that enters the box body 2 from the air inlet hole 3 and is discharged from the box body 2 by the exhaust fan 1. During use, dust is sucked into the interior of the box body 2 from the air inlet hole 3, and then discharged by the exhaust fan 1 after being filtered by the filter screen 12. The dust adheres to the filter screen 12.
[0027] Water is supplied into the spray pipe 11 through the water supply pipe 7 and then sprayed out by the nozzles 13 to form a water mist, washing the part of the filter screen 12 located in the sewage discharge bin 5 clean. The sewage falls to the bottom of the sewage discharge bin 5.
[0028] As the filter screen 12 rotates, the dust is continuously washed into the sewage discharge bin 5 for collection. After the dust collection is completed, the sewage discharge bin 5 can be opened for cleaning, or a sewage discharge pipe 6 can be connected to the bottom of the sewage discharge bin 5 for direct sewage discharge.
[0029] In addition, the main shaft 10 and the auxiliary shaft 9 can be slightly inclined, with the main shaft 10 slightly lower than the auxiliary shaft 9, making the filter screen 12 slightly inclined to facilitate the concentrated downward fall of the water for washing the filter cloth 12.
[0030] The utility model collects dust through a rotatable filter cloth, and then forms a water mist through the nozzles 13 to wash the part of the filter screen 12 that rotates into the sewage discharge bin 5. Thus, while cleaning the filter screen 12, the dust can be collected, avoiding the cumbersome steps of continuously replacing the filter screen 12 in traditional dust collection devices. In addition, the filter screen 12 wetted by water can make the dust better adhere to the surface and then be washed into the sewage discharge bin 5 as the filter screen 12 rotates, with better dust collection effect. Embodiment 2
[0031] This embodiment is further optimized on the basis of the above embodiment. Specifically:
[0032] As Figure 4 , the spray pipe 11 is in a long strip-shaped annular structure, and more nozzles 13 can be arranged to improve the efficiency of washing the filter screen 12.
[0033] As Figure 1 and Figure 3, a detachable drawer 8 is provided at the bottom of the box body 2. After a large amount of dust adheres to the wet filter screen 12, it may agglomerate and fall off. When the agglomerates fall off, the drawer 8 can be used for collection.
[0034] The present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present utility model, and the changed content still falls within the protection scope of the present utility model.
