Abstract
The present invention provides a mixer having a duct into which a fluid (or fluids) is (or are) inducted and a stirrer disposed within the duct and adapted to stir and/or mix the fluid (or fluids) by repeating division and join on the fluid (or fluids) when the fluid (or fluids) moves (move) through the duct. The stirrer has a vane device dividing the interior of the duct into a plurality of spaces and openings formed in the vane device and through which the fluid (or fluids) moves (move) from one space to another. The mixer further includes a vibrator for vibrating the stirrer at a desired frequency. The vibrator may be of any one of various types vibrators such as an electromagnetically driven type vibrator consisting a coil and a permanent magnet, a motor drive type vibrator consisting of a motor-cam mechanism of a cam-follower mechanism and the like. The vibration of the duct or stirrer from the vibrator basically greatly increases the efficiency of the same stirring action as in the static type mixer and is also useful to eliminate any clogging on mixing powdery fluids. In addition, the vane may be in the form of a spiral screw-shaped vane which can exert a propelling force to…
