Description
Technical field
The invention belongs to powder raw material manufacture field, and in particular to a kind of weight-loss type for powder material continuous charging
Drawing-in device and feeding method, especially a kind of weight-loss type drawing-in device continuously accurately fed for energetic material powder material
And feeding method.
Background technology
Accurate production is the optimal mode of production of the industries such as energetic material, and the amount of testing of reaction solution can be greatly decreased,
And ensure reaction solution consistence of composition, so as to ensure the high-quality of product quality；Accurate charging be ensure accurate production must
Condition is wanted, feeding quantity can only be adjusted by detection reaction solution composition without accurately charging, although on-line checking can be detected in time
The concentration deviation of reaction solution, and feeding quantity is adjusted, because detection has hysteresis quality, therefore there is gap with accurate production.
Energetic material industry quantity-produced powder charging precision is not high always, and the accuracy of belt scale for using at present reaches
1% but still the accurate quantity-produced requirement of energetic material can not be met.
Common weight-loss type feeding machine precision is up to 0.5% in the prior art, but because the defect of its metering method is determined
It is applied to interruption powder charging, there is a problem of continuously precisely measuring in continuous accurate production process：It is to pass through
Weightlessness is calculated and controls charging rate, and when powder material, material is reduced to minimum material position in feeder feed bin during charging
When must carry out feed supplement, material position can gradually add to highest from minimum during feed supplement, be mended on whole feed supplement process feeding machine side
The discharging of material side.But because itself design defect of its measuring principle occurs that weight of material weighs the larger error of appearance and not can determine that
Accurate charging, this stage is referred to as the precision stage out of control.In order to make up this defect, prior art is mended in weight-loss type feeding machine
This stage of charging is carried out during material by the variable-frequency motor frequency by memory to control, or by the change after the change for calculating material position
Frequency electric machine frequency curve come control with assume a fixed feeding quantity carry out charging and control program computing, cause add up mistake
Difference and charging error, make the precision and material in this stage that weight-loss type feeding machine fed in feed supplement it is accumulative occur it is out of control
Or the phenomenon that cannot accurately measure；Therefore can not to meet energetic material accurately continuous for common weight-loss type feeding machine of the prior art
The requirement of production.
The content of the invention
