device of feeding from the bottom and mixing of material accumulation, particularly useful in the process of rapid composting of municipal solid waste putrescibili and method of use

摘要

The invention relates to a device for feeding material from below to a tip and to the mixing of the material in the tip, in particular for the rapid composting of quickly rotting municipal refuse. In order to obtain a good compost, the centrally fed material can be initially conveyed downwards, then outwards and subsequently upwards by an outer conveyor worm (10) and at the same time - if appropriate whilst retaining an upper insulating layer - mixed with the material of the tip (11) by means of a central pipe (1) which is fixedly arranged on a transporting device (3), a rotatable outer tube (7) and an inner conveyor worm (8), a blade distributor (9) and the outer conveyor worm (10).
