Waste gas filtering device for cleaning nano magnetic beads

The utility model discloses a waste gas filtering device for cleaning nano magnetic beads, which is mainly used for treating generated waste gas in the process of cleaning the nano magnetic beads, so that the gas can be directly discharged into external air subsequently. A first motor is placed at the upper end of the device shell; the stirring shaft is connected with the output end of the first motor, and the stirring shaft and the device shell form a rotating mechanism through a bearing mounted on the device shell; the stirring rods are symmetrically arranged outside the stirring shaft; comprising a fixing plate installed on the inner surface of the device shell. According to the waste gas filtering device for nanometer magnetic bead cleaning, through rotation of a stirring rod, cleaning liquid in the device shell can be stirred in the process that nanometer magnetic beads are put into the device for cleaning, and the situation that the cleaning liquid precipitates is avoided; the waste gas is fully filtere
