The utility model provides a pair of wear wall hood with self-cleaning function, beneficial effect lies in: this device simple structure can reach the automatically cleaning purpose, does not need artifical clearance filterable impurity, simultaneously owing to adopt the pipe sheathed tube mode, the inlet port sets up including pipe circumference, and the resistance of admitting air is little, reduces the load of new trend fan.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the sealing device comprises a first plugging piece 1, an inner pipe 2, a screw rod 3, a soft plastic sealing piece 4, a nut 5, an outer pipe 6, a bottom plate 7, a rotating shaft 8 and fan blades 9.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a wall-through hood with a self-cleaning function comprises a fresh air pipeline and an outer pipe 6 penetrating through a wall body, wherein the total length of the outer pipe 6 is 400-500mm, preferably 450mm, the end of the outer pipe 6 arranged indoors is connected with the fresh air pipeline, an inner pipe 2 is coaxially arranged inside the outer pipe 6, the inner pipe 2 is fixed inside the outer pipe 6 through a bracket, an air channel is reserved between the inner wall of the outer pipe 6 and the outer wall of the inner pipe 2, the end of the inner pipe 2 pointing indoors is sealed through a bottom plate 7, the end of the inner pipe 2 pointing outdoors is open, the end of the inner pipe 2 pointing outdoors is sealed through a first plugging part 1, a plurality of holes for ventilating and flowing dust are circumferentially arranged on the inner pipe 2, a spiral rod 3 is arranged inside the inner pipe 2, brush bristles are circumferentially arranged on the spiral rod 3, the brush bristles are tangent to the inner wall of the inner pipe, a rotating shaft 8 is rotatably connected to the axis of the bottom plate 7, and a fan blade 9 is fixedly connected to the end of the rotating shaft 8 arranged outside the inner pipe 2, one end of the rotating shaft 8 arranged in the inner tube 2 is fixedly connected with the screw rod 3.
When a fresh air pipeline of a fresh air system is used for exhausting air, outdoor air flow enters the air channels of the inner pipe 2 and the outer pipe 6 through the opening of the inner pipe 2 and a hole for ventilating and flowing dust of the inner pipe 2, air flow impurities are blocked by the hole, finally clean air flow is blown on the fan blade 9 and sent into the fresh air pipeline, the fan blade drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the screw rod 3 to rotate, the impurities filtered on the inner wall of the inner pipe 2 are brushed off by bristles on the screw rod 3, and the brushed impurities are pushed out of the room by the screw rod 3 to achieve the purpose of self-cleaning.
