Mobile apparatus and method for producing concrete with cooling of bulk material

摘要

The invention relates to a mobile apparatus and a method for concrete production, comprising a cooling apparatus for cooling bulk material, in particular aggregates for concrete production. The cooling apparatus (100) comprises a bulk material hopper (110), a wetting apparatus (120) and an air supply apparatus (130). The cooling apparatus has a bulk material feeder (140) for feeding bulk material into the bulk material hopper via a bulk material feeder path (141), the bulk material feeder and the wetting apparatus being adapted and disposed in such a way that bulk material to be fed comes into contact on at least one part of the bulk material feeder path with water that is being discharged from the wetting apparatus.

1. A mobile apparatus for concrete production, comprising a cooling apparatus for evaporatively cooling bulk material, including aggregates for concrete production, said cooling apparatus comprising a bulk material hopper, a wetting apparatus and an air supply apparatus,
characterised in that the cooling apparatus is disposed in a frame corresponding to a container, and the cooling apparatus has a bulk material feeder for feeding bulk material into the bulk material hopper via a bulk material feeder path, said bulk material feeder comprising a bulk material feeder shaft which extends upwards from the bulk material hopper and in which a zigzag vibrating conveyor is arranged, wherein bulk material to be fed is guided on several parts of the bulk material feeder path on a path of movement corresponding substantially to free fall of the bulk material, the bulk material feeder and the wetting apparatus being adapted and disposed in such a way that bulk material to be fed comes into contact on at least one part of the bulk material feeder path with water that is being discharged from the wetting apparatus, and is guided on said part of the bulk material feeder path on a path of movement corresponding substantially to free fall of the bulk material, and the bulk material hopper is closed airtight, except for the outlet through bulk material feeder shaft, such that the air blown into the bulk material hopper by the air supply apparatus can only exit the bulk material hopper via the zigzag vibrating conveyor in a direction opposite to the bulk material feeder path;characterised by an air discharge apparatus; andcharacterised in that the wetting apparatus, the air discharge apparatus and an air cooling device are adapted and disposed in such a way that an air outlet of the air discharge apparatus is connected to an air inlet of the air cooling device and a water outlet of the air cooling device is connected to a water inlet of the wetting apparatus.
