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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, an air filter device comprises a cylinder body and a cone body 1, wherein the cylinder body comprises an outer cylinder body 2 and an inner cylinder body 3; an air inlet 4 is formed in the outer side of the outer cylinder 2, an inner cylinder 3 is fixedly arranged in the outer cylinder 2, and a cone 1 is arranged at the lower part of the outer cylinder 2; an outlet pipe 5 is arranged in the inner barrel 3, the lower end of the outlet pipe 5 and the lower end of the inner barrel 3 are positioned on the same horizontal plane, the top of the outlet pipe 5 penetrates through the top of the outer barrel 2 and extends out of the outer barrel 2, the bottom of the outlet pipe is sealed, and a filter screen 6 is arranged in the middle of the pipe body; a rotational flow plate 7 is arranged at the inner lower part of the inner cylinder 3, the excircle of the rotational flow plate 7 is fixedly connected with the inner wall of the inner cylinder 3, and the inner circle of the rotational flow plate 7 is fixedly connected with the outer wall of the outlet pipe 5; the cone 1 is connected with the outer cylinder 2 in a sealing way, and the lower part of the cone 1 is provided with a valve 9.
In this embodiment, a plurality of air inlets 4 are equidistantly formed on the outer side of the outer cylinder 2. As shown in fig. 2, a wire mesh 10 is provided at the air inlet 4. The aperture of the silk screen 10 is 1 cm.
In this embodiment, the middle of the inner cylinder 3 is provided with a mesh or grid, and the mesh or grid is wound with a filter screen 6. The aperture of the filter screen 6 is 10-30 meshes.
