Problems solved by technology

For some industries, the medium discharged by the centrifugal fan contains greasy components. After a long time of use, a large amount of oil will flow out along the front and rear sides of the fan casing and flow to the surrounding sites, and the oil adsorption fibers will become Inflammables, polluting the surrounding environment and easily causing fire and other safety accidents, bringing hidden dangers to production safety

Abstract

The invention discloses a centrifugal fan which comprises a fan shell, a wind collection ring, an impeller and a motor, wherein the fan shell is internally provided with the wind collection ring and the impeller, the motor is arranged outside the fan shell, an output shaft of the motor is connected with the impeller, and a first dripping pan and a second dripping pan are respectively arranged at the front side and the rear side of the fan shell; the first dripping pan is positioned below the wind collection ring; the second dripping pan is positioned below the output shaft of the motor; and oil drain pipes which are communicated with the dripping pans are arranged below the first dripping pan and the second dripping pan. According to the centrifugal pan, after the centrifugal fan is used for conveying oily substance-containing medium for a long time, a great amount of oil stains flow out along with the front side and the rear side of the fan shell, and flows in the first dripping pan and the second dripping pan in the first time, so that pollution to the ambient environment can be avoided, the occurrence of safety accidents such as fire disaster can be prevented, and hidden production safety hazard can be eliminated.

Description

technical field [0001] The invention relates to a fan, in particular to a centrifugal fan. Background technique [0002] Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is widely used in power plants, mines and other industries. For some industries, the medium discharged by the centrifugal fan contains greasy components. After a long time of use, a large amount of oil will flow out along the front and rear sides of the fan casing and flow to the surrounding sites, and the oil adsorption fibers will become Inflammable materials, polluting the surrounding environment and easily causing fire and other safety accidents, bringing hidden dangers to production safety. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a centrifugal fan that can avoid pollution to the surrounding environment and prevent safety accidents such as fi...
