Abstract
The utility model discloses an exhaust fan used in a chemical experiment. The exhaust fan comprises a clamping plate, wherein a fixed sleeve is fixedly arranged on the clamping plate; a telescopic rod is arranged in the fixed sleeve; the fixed sleeve is provided with a fixing bolt which can be used for fixing the telescopic rod; the clamping plate is in threaded connection with the bolt; the end part of the bolt is provided with a pressure plate; the telescopic rod is connected with a shell; the shell is provided with an air suction hole; the top of the shell is provided with a suction fan; the suction fan is communicated with the air suction hole; the suction fan is communicated with a conveying air pipe; a pipe joint is connected to the conveying air pipe; a filtering device is arranged between the conveying air pipe and the pipe joint; and the thickness of a non-woven fabric layer is 3 millimeters. During working, the suction fan works, and waste gas enters the filtering device through the conveying air pipe and is exhausted via the filtering device. When the exhaust fan is applied to the chemical experiment, waste gas can be exhausted conveniently, and the environmental pollution caused by waste gas is lowered.
