Abstract
A system includes a first pump to meter colorant and a second pump to pressurize a mixture of water and the colorant. Also included is a mixer body defining a chamber with an inlet and an outlet and one or more liquid input ports in fluid communication with the second pump to receive the mixture. The chamber receives solid pieces through the inlet and discharges the pieces through the outlet. One or more rotary conveying members are included that are positioned in the chamber to intermix the mixture and the solid pieces and convey the solid pieces from the inlet to the outlet. These members can be rotated by one or more drivers. A process and system for treating cinders are also disclosed.
Claims8
A system, comprising:
- a first pump to meter colorant;
- a second pump in fluid communication with the output of the first pump and a water supply input to pressurize a mixture of water and colorant;
- a mixer body including a chamber with an inlet and an outlet and one or more liquid input ports in fluid communication with said second pump to receive the mixture under pressure, said chamber being configured to receive solid pieces through said inlet and to discharge the pieces through said outlet;
- a first rotary conveying member positioned in the chamber adapted to convey the solid pieces from the inlet toward the outlet;
- a second rotary conveying member positioned in the chamber to intermix the mixture and the solid pieces and to convey the solid pieces to the outlet;
- and
- one or more drivers operable to provide rotational mechanical power to rotate the first and second rotary conveying members at different speeds relative to one another.
A system comprising:
- a first pump to meter colorant;
- a second pump to pressurize a mixture of water received from a water supply and colorant received from the first pump;
- a mixer body including a chamber with an inlet and an outlet and one or more liquid input ports in fluid communication with said second pump to receive the mixture under pressure, said chamber being configured to receive solid pieces through said inlet and to discharge the pieces through said outlet;
- one or more rotary conveying members positioned in said chamber to intermix the mixture and the solid pieces and to convey the solid pieces from the inlet to the outlet, at least one of said one or more rotary members including a shaft with a number of fixed paddles and a number of adjustable-pitch paddles;
- and
- one or more drivers operable to provide rotational mechanical power to rotate said one or more rotary conveying members.
A system, comprising:
- a pump connected to a source of colorant;
- a mixer body including a chamber with an inlet and an outlet and one or more liquid input ports in fluid communication with said pump to receive the colorant, the chamber being configured to receive solid pieces through said inlet and to discharge the pieces through the outlet;
- one or more rotary conveying members positioned in the chamber to intermix the colorant and the solid pieces and to convey the solid pieces from the inlet to the outlet, at least one of the one or more rotary members comprising a shaft with a plurality of adjustable-pitch paddles;
- and
- one or more drivers operable to provide rotational mechanical power to rotate the one or more rotary conveying members.
A system, comprising:
- a pump in fluid communication with a colorant source;
- a mixer body including a chamber with an inlet and an outlet and one or more liquid input ports in fluid communication with said pump to receive the colorant, the chamber being configured to receive solid pieces through said inlet and to discharge the pieces through the outlet,
- a first rotary conveying member positioned in the chamber for conveying solid pieces from the inlet toward the outlet;
- a second rotary conveying member positioned in said chamber to intermix colorant and solid pieces and to convey solid pieces to the outlet;
- and
- one or more drivers operable to rotate said rotary conveying members at different speeds relative to each other.
