Abstract
This is a dynamic measure method for surveying the materials, which are on the transporting device. On the transporting device is installed a sensor to monitor the data of material's mass flow quantity, and send this data to processor to calculate the transported materials mass and flow quantity. The accurate degree is according to the data's accurate and the survey method.
Description
Technical field
The present invention relates to a kind of metering method and device to mass flow and quality, is a kind of method and apparatus of dynamic measurement.
Background technology
In industrial material conveying process, need the mass transport flow is monitored and measured.The method and apparatus that uses has at present:
1, the use LOAD CELLS is weighed and is measured.Method is LOAD CELLS to be installed weigh and measure on equipment such as belt conveyor, storage bin, bearing platform, has belt claim, weigh storehouse, rotor to claim etc. in this kind equipment.
2, realize material metage by metering to quality of material kinetic energy.Method is that the relation of measuring and demarcating material kinetic energy and quality is measured weighing and metering by kinetic energy, and this kind equipment has the flowmeter of impact, Coriolis scale etc.
3, liquid material can the flow metering of use traffic instrumentation amount.
Above-mentioned all methods all need to use a special metering outfit.This kind equipment general precision is had relatively high expectations, thereby equipment cost is also high, in order to realize that in course of conveying metering needs metering outfit is installed, has increased system and construction investment simultaneously.
Summary of the invention
The present invention proposes fully metering method different from the past, promptly do not use LOAD CELLS also not measure quality of material kinetic energy, is to realize metering to material by the measurement to the energy consumption in the material conveying process.Material can be subjected to displacement in being transferred process, and the energy that this displacement consumed equals 1/2mV
2+ mh (m=quality, V=speed, h=displacement height).Measure the energy that conveying equipment consumes, deducting various losses is exactly the energy that the material displacement consumes, and can calculate the flow and the quality that have been transferred material thus.
Sensor installation on conveying equipment, utilization obtains the required every data of calculated mass flow to the monitoring of conveying equipment, the various data that record from conveying equipment are sent into data processing unit and are carried out computing and draw the quality and the flow of convey materials, and measuring accuracy depends on DATA REASONING precision and computing method.
Conveying equipment of the present invention is suitable for equipment and the pump apparatus that hoister, belt feeder, worm conveyor etc. can make material generation level and perpendicular displacement.Data processing unit is suitable for computing machine, Programmable Logic Controller, single-chip microcomputer and has the instrument of data-handling capacity.
The present invention uses the present invention and can simplify process system because be to utilize the measurement to conveying equipment to realize metering, special-purpose metering outfit in the saving system and corresponding technology, construction investment.
Specific embodiments
The present invention is applicable to various conveying equipments, only is that example is made a detailed description below with the hoister:
Electric current, voltage and the pulling speed of electric current, voltage, speed pickup measurement hoister are installed.Sensor signal inserts data processing unit, and data processing unit can use a computer or Programmable Logic Controller or single-chip microcomputer or have the instrument of data-handling capacity.
Computing method
M-quality of material, i-hoister electric current, u-hoister voltage, t-time, η in the formula
1-electric efficiency, η
2-mechanical efficiency, k-correction factor, v-Hoist Speed, g-acceleration of gravity, h-hoisting depth.Need to prove η under the situation that flow varies in size
1η
2Be vicissitudinous, need be when system debug to the result of calculation materials calibration, error is proofreaied and correct with correction factor.The situation difference was very big when hoister started in the docking process with even running, can use with starting current be that the mathematical model of function is to improve precision.
