PURPOSE:To mix powder and liquid in such a way that the mixing ratio of both is kept always constant by constituting a continuous type mixer for powder and liquid of a powder charging upper vessel provided with scraping vanes and a lower vessel provided with a liquid lead-in port and an impeller. CONSTITUTION:While a motor 9 is being driven, a constant amount of liquid is supplied through a liquid lead-in port 3 into a lower vessel 1, and a constant amount of powder is charged through a powder lead-in pipe 6 into an upper vessel 2. The powder is dropped from the top of a guide wall 7 onto a rotating impeller 11 of the vessel 1 by the rotation of scraping vanes 13 mounted to an arm connected to the motor 9. The liquid supplied through the port 3 passes between a lower partition plate 15 and the vessel bottom, is moved as if to be released from the impeller 11 by blades 16, and is mixed with the powder by the impeller 11. Further, these are allowed to collid against stationary vanes 18 by the velocity energy during agitating and are thereby thoroughly mixed. The mixture is removed through a discharge pipe 5. Since the entire amount of the charged powder is mixed, the fluctuation in mixing ratios does not occur. |
