Compared with the prior art, the utility model discloses there is following advantage:
the utility model discloses at the peripheral drainage screen panel that goes up of impeller of fan, the material is followed air intake department and is inhaled feed opening by the impeller, and later the material reachs impeller department, is blown off from discharge opening by the impeller again, follows the outside transport away of air outlet promptly. In the process, the material particles are conveyed inside the water filtering screen cover and driven to flow by wind power, but the water in the material particles passes through the water filtering screen cover and sinks to the bottom of the sealing shell, and the water draining structure at the lower part of the sealing shell can drain the settled water in time. The utility model discloses a fan drainage device can filter most moisture in the material, alleviates the load of fan load and follow-up drying process.
Drawings
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view of the present invention;
fig. 2 is an exploded view of the present invention.
Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
A fan drainage device as shown in fig. 1 to 2, which comprises a fan for conveying materials, wherein the fan comprises a driving motor 1 and an impeller 2 arranged on an output shaft of the driving motor 1, a sealing shell 3 for enclosing the impeller 2 in a cavity of the impeller 2 is arranged outside the impeller 2, an air inlet 31 and an air outlet 32 are arranged on the sealing shell 3, and a water filtering screen 4 is arranged between the impeller 2 and the sealing shell 3, wherein the mesh size of the water filtering screen 4 needs to be adapted to the size of material particles, i.e. the mesh size of the water filtering screen 4 only allows water to pass through but not allows the material particles to pass through; the water filtering screen 4 surrounds the impeller 2, a feeding opening 41 is formed in the position of the air inlet 31 of the water filtering screen 4, a discharging opening 42 is formed in the position of the air outlet 32 of the water filtering screen 4, and a water discharging structure is arranged on the lower portion of the sealing shell 3. Namely, the utility model discloses at 2 peripheral water screen covers 4 that strain of impeller of fan, the material is followed air intake 31 and is located by impeller 2 suction feed opening 41, and later the material reachs impeller 2 department, is blown off from discharge opening 42 by impeller 2 again, follows the outside transport away of air outlet 32 promptly. In the process, the material particles are conveyed inside the water filtering screen 4 and driven to flow by wind power, but the water in the material particles passes through the water filtering screen 4 and is settled to the bottom of the sealing shell 3, and the settled water can be discharged in time by the drainage structure at the lower part of the sealing shell 3. The utility model discloses a fan drainage device can filter most moisture in the material, alleviates the load of fan load and follow-up drying process.
More specifically, the side wall of the feeding opening 41 is closely attached to the inner wall of the air inlet 31. The air inlet 31 is connected with an input pipeline for inputting materials, and after the materials reach the air inlet 31, in order to ensure that the materials completely enter the water filtering mesh enclosure 4 from the feeding opening 41, the side wall of the feeding opening 41 is tightly attached to the inner wall of the air inlet 31, so that no gap for leakage exists between the side wall of the feeding opening 41 and the inner wall of the air inlet 31.
