Abstract
A mixing device for mixing flowable materials, especially dry materials, such as pulverant or powdered materials, in which a pair of inlet conduits have the downstream ends connected to a fitting which is also connected to the upstream end of a discharge conduit with a valve for selectively controlling the downstream ends of the supply conduits. Separate supply chambers are connected to the upstream ends of the supply conduits and charge a respective material into the associated supply conduit in conformity with the setting of the flap valve. A secondary mixing device is connected to receive mixed material in the discharge conduit for further mixing of the material while air may also be extracted from the material.
Claims20
In a device for mixing flowable materials, especially dry materials, comprising;
- at least a pair of supply conduits each adapted to convey a respective material, a discharge conduit, a fitting connected to the downstream ends of said supply conduits and to the upstream end of said discharge conduit, valve means selectively operable for closing off either one of the discharge ends of said supply conduits, and means for supplying materials to the supply conduits under control of the valve means positioned alternately to block and to permit discharge of material from the respective conduit.
In a device for mixing flowable materials, especially dry materials, comprising;
- at least a pair of supply conduits each adapted to convey a respective material, a discharge conduit, a fitting connected to the downstream ends of said supply conduits and to the upstream end of said discharge conduit, valve means selectively operable for closing off either one of the discharge ends of said supply conduits, and a secondary mixing device connected to the downstream end of said discharge conduit.
In a device for mixing flowable materials, especially dry materials, comprising;
- at least a pair of supply conduits each adapted to convey a respective material, a discharge conduit, a fitting connected to the downstream ends of said supply conduits and to the upstream end of said discharge conduit, valve means selectively operable for closing off either one of the discharge ends of said supply conduits, and a further mixing device having said discharge conduit as one supply conduit and a further conduit as the second supply conduit.
In a device for mixing flowable materials, especially dry materials, comprising;
- at least a pair of supply conduits each adapted to convey a respective material, a discharge conduit, a fitting connected to the downstream ends of said supply conduits and to the upstream end of said discharge conduit, valve means selectively operable for closing off either one of the discharge ends of said supply conduits, respective supply chambers at the upstream ends of said supply conduits, and venturi charging devices connecting each chamber with the respective supply conduits.
