The upper section includes the filtering battery made of polyester filtering sleeves, equipped with a compressed air tank (with ATEX certified electro valves) for the sleeves cleaning by counter current jet pulses, automatically activated when needed, upon the pressure loss of the filters. The filter housing output is flanged for connecting to the pipework and to the fan.
The lower section is the waste storage chamber, equipped with strong adjustable support legs and thick flat bottom to support the multi-leaf double spring extractor. The rotating springs, made of harmonic steel, move the waste toward 3 possible simultaneous hopper outlets. One outlet is connected to a plastic bag for an emergency discharge, while the 2 remaining outlets can be connected to a briquetting machine, a pneumatic transfer system to a container and a screw conveyor to feed a biomass boiler. An inspection door provides easy extractor maintenance, and Lexan windows allow visual inspection of the material within the silo, as well as one or more level indicators.
