Description
Technical field
The present invention relates to particulate material batching technical field, in particular to a kind of particulate material metering device.
Background technology
The metrology applications of particulate material in a lot of industries, such as grain and oil, brewage, chemical industry, fertilizer etc. production and processing industry, all need
Granular material is accurately measured, common this kind of particulate material typically has certain granularity, such as particle diameter 0.1～
3 millimeters.The use more to the measurement technology of particulate material generally requires, in technology of the package, the material for exporting a certain specified rate,
And need to repeat metering in a large number, the volume under this condition of work using a normal volume is relatively good to measure.Current
Particulate material is sent into hopper by conveyor screw machine as join on the equipment such as fertilizer in Blending Fertilizer by the multiplex weighing balance of metering form,
When controlling organization is detected and reaches preset weight, stop the motion of conveying mechanism；This kind of form occurs when conveyor screw machine
Measuring accuracy during the not smooth and feeding of blanking unstable situation it is difficult to ensure that, in addition if desired quick metering when, its speed
Can not more take into account with precision.Therefore in these use occasions it is thought that by dividing into conveying sheave in hopper, by control
Revolution reaches the metering of weight or volume, transports material in packaging bag while metering.In theory, metering sheave will be counted
Amount fully digitalization, it should more accurate than general weighing balance, but actually by conveying sheave, to measure still, there are the following problems：
If one is that the material in measuring tank is unable to the complete blowing of each rotation guarantee, random accumulation will be produced, and then affects metering
Precision；Two is that most of materials generally have stronger hygroscopicity, containing higher moisture content, generally in 3%～8% moisture content,
Such as fertilizer etc., is easily caused measuring tank and makes moist, and then aggravates sizing, and its result is to cause error in dipping too big, or even cannot count
Amount, there is a big difference with theoretic accurate metering for this；This is also the maximum barrier that metering sheave cannot be used for accurate metering at present
Hinder.
