Abstract
The invention relates to a mixing and conveying device for mixing and subsequently conveying semifluid materials, in particular mortar and concrete. The device comprises a compressor for generating compressed air, and a mixing vessel connected to a conveying conduit and an agitator gear. The mixing vessel is charged with the material to be mixed and conveyed, and compressed air is admitted into the mixing vessel for discharging the semifluid materials through the conveying conduit. The agitator gear is driven by at least one compressed air motor that is supplied with a proportion of the compressed air generated by the compressor.
Claims30
A mixing and conveying device for discontinuous mixing being interrupted by feeding processes, and conveyance of semifluid materials, comprising:
- a mixing vessel (14);
- a conveying conduit (26) connected to the mixing vessel (14);
- a motor-driven agitator gear (13) connected to the mixing vessel (14);
- a compressor element (3) connected to a power source for generating compressed air;
- and
- at least one compressed air motor (12) connected to and driving the agitator gear (13), and being supplied with compressed air from the compressor element (13);
- wherein the mixing vessel is filled with the material being mixed and conveyed, the material is discharged through the conveying conduit (26) by the compressed air generated in the compressor element (3).
A method for operating a mixing and conveying device for discontinued mixing, interrupted by feeding processes and conveyance of semifluid materials, comprising:
- charging a mixing vessel with the material to be mixed and conveyed, said mixing vessel being connected to a conveying conduit and a-motor-driven agitator gear (13);
- generating compressed air in a compressor element, and supplying said compressed air to at least one compressed air motor;
- and
- discharging the semifluid material from said mixing vessel via said conveying conduit when said mixing vessel is acted upon by the compressed air;
- wherein during a mixing phase the compressed air only supplies said compressed air motor (12) and wherein during a conveying phase the compressed air conveys the semifluid material and supplies said compressed air motor (12).
