The double offset rotatory feeder valve biomass feeding system, the quantity of revolving vane is on the central axis
4-8.
The double offset rotatory feeder valve biomass feeding system, the extended corner of the transitional slope are 15-
30°。
A kind of feeding method of double offset rotatory feeder valve biomass feeding system, this method comprises the following steps: raw
Material charge is fallen into through the blanking port on feed valve chest, and compartment, biomass material are formed between each adjacent two revolving vane
It drops into compartment, with the rotation of revolving vane, compartment, which is rotated to level-one offset rotatory feeder valve exit, enters second level
Offset rotatory feeder valve is passed through 1- in level-one offset rotatory feeder valve and second level offset rotatory feeder valve connectivity part
The gas of 10Kpa, level-one offset rotatory feeder valve rotate clockwise, and second level offset rotatory feeder valve rotates counterclockwise, raw
Material charge is discharged through second level offset rotatory feeder valve by discharge port, and realization continuous-feeding is looped back and forth like this.
The utility model has the advantages that
1. present system is simple and reliable, feed is stablized, and material applicability is wide, is suitable for rice husk, biomass block, biomass
Grain etc..
2. the present invention is suitable for using surge chamber pressurising and the dual-seal of offset rotatory feeder valve, good airproof performance to close
The more demanding positive pressure feeding system of envelope property.
3. blanking port of the present invention is eccentrically set on the side of revolving vane uplink, blanking port and housing junction are equipped with transition
Slope avoids the meeting point of revolving vane and shell from getting too close to feeding zone, material is caused to cause bite at meeting point.
