Description
One, technical field
The invention belongs to the granular material self-measuring device, relate in particular to a kind of granular material self-measuring device under flow state.
Two., technical background
Need to use a large amount of granular materials in commercial production and the engineering construction.The bulk cement that will use in the building operation particularly, use amount is big, require metering speed fast, and the cement environmental pollution is serious, responsive to airborne wetness reaction, and present employed sensor electronics scale static weighing or the fast response transducer static weighing of being of domestic and international most of users, as " a kind of self-measuring device of granular material " (ZL97209417.2), the degree of accuracy of metering is limited; Continuous powder dispensing installation withflow regulatory circuit-computes rate of delivery from continuous weighings inconjunction with powder density and controlled duct characteristics (WO9007740) is affected because of the lack perseverance press mechanism makes degree of accuracy; " novel rotor weigher " (CN89219398.0) adopts LOAD CELLS slow to environmental requirement height, cost height, speed; Germany Pf company product, Chinese patent, their weak point just is that speed is slow.Also having on the documents and materials to propose to measure its weight by the granular material volume, but because the bulk density of most of granular materials is not a constant, is 0.9T/m as the bulk density of cement
3～1.7T/m
3, and be difficult to be applicable to the metering of variety classes granular material.
Three, summary of the invention
The purpose of this invention is to provide the device that under flow state, can carry out automatic gauge that a kind of speed is fast, accuracy is high, cost is low to different inviscid granular materials.
To achieve these goals, the technical solution adopted in the present invention is: the centerline at housing is equipped with the auger thruster movingly, the angle of rake right-hand member of auger is installed in the right-hand member of housing, the angle of rake left end of auger is installed in the center of resistance net, the auger thruster by kinematic train by direct motor drive, photoelectric sensor is equipped with at the place at the angle of rake axle of auger right-hand member, and photoelectric sensor links to each other with computer control system; The resistance net is positioned at the discharging opening right side and is fixed on the circle of housing, in the left side of discharging opening the constant voltage door is housed.
The angle of rake pressure surface of described auger is the helicoid of varying pitch, and the interior circle of the cylindrical of this helicoid and housing is for movingly.
The right-hand member fixed connection of the center of described constant voltage door and automatic constant-pressure telescoping mechanism, the left end of automatic constant-pressure telescoping mechanism is installed in the center of division board movingly, and fork constant voltage depression bar is pressed in the end of automatic constant-pressure telescoping mechanism left end.
Described automatic constant-pressure telescoping mechanism by kinematic train by direct motor drive.
On the angle of rake axle of described auger the little vibrating device of high frequency is housed, the little vibrating device of high frequency is positioned at the below of charging aperture.
Because adopt technique scheme, the present invention can carry out automatic gauge quickly and accurately to inviscid granular materials different under the flow state, has simple in structure, with low cost, characteristic of strong applicability.
