Mixing machine

摘要

A mixer 1 for thermal treatment of a material for mixing consisting of solid particles comprises a mixing vessel 2 for admitting the material for mixing. The vessel 2 has at least one thermal medium channel that with its surface gets at least partially in contact with the solid particles to be heat-treated, through which thermal treatment media are fed when the mixer 1 is in operation. Additionally, the mixer 1 has available a device for circulating the material for mixing found in the container 2. The container 2 is turnably supported about an axis R that penetrates the two front sides 7, 20. A motorized drive 17, 18, 18.1 serves as a circulating device to turn the container 2.

1. A mixer for thermal treatment of a material for mixing consisting of solid particles comprising:
a mixing vessel for receiving the material for mixing mounted in a rack; the mixing vessel having a dual wall and at least one thermal medium channel that has a surface that at least partially contacts with the solid particles to be heat-treated; thermal treatment media are fed through the thermal medium channel when the mixer is in operation; a device for circulating the material for mixing situated in the mixing vessel, said device having a first axis of rotation along a longitudinal axis of the mixing vessel and a second axis of rotation transverse to the first axis of rotation; the mixing vessel is turnably supported in the rack about the first axis of rotation transversing two front sides of the vessel and with a motorized drive that is provided as a circulating device for turning the vessel; the mixing vessel being pivotably supported in the rack to allow the vessel to rotate around the second axis of rotation from a first filling position, to a mixing position where the first axis of rotation is substantially horizontal and then to second emptying position; wherein the vessel around its circumference has multiple thermal treatment channels; wherein the vessel has structures being hollow strips projecting inward in a radial direction for enlarging its inner surface; wherein the structures projecting inward are implemented as thermal medium channels; wherein each of the thermal medium channels has an inside for containing the thermal treatment media, which inside is not in fluid connection with an inside wall of the mixing vessel for receiving the material for mixing during a mixing procedure, such that thermal treatment media inside the thermal medium channels are kept separate from material for mixing inside the mixing vessel when the mixer is in operation; a thermal medium inlet line and a thermal medium drain line in fluid connection with the thermal medium channels; and the thermal medium inlet and the thermal medium drain line each in fluid connections with a feed through such that the thermal treatment media is circulated into and out of the thermal medium channels of the mixing vessel while the mixing vessel is rotating around the first axis of rotation.
