Abstract
The invention discloses a rotary container intelligent pressure measurement system, and the following dynamic stable pressure source connects with the PID control regulating valve opened with the gas source, and through two gas pipes, the following dynamic stable pressure source respectively connects with the upper and lower probes located in the upper and lower parts of the rotary container, and there are hole boards above the two gas pipes; a first pressure difference transmitter of one receiving hole board both sides pressure difference signal controls the work of the instrument control regulating valve through the PID; above the two gas pipes, and between the hole board and the probe, there is the second pressure difference transmitter to reflect the measured material thickness in the rotary container. Through the input of consecutive and steady low-speed jet gas flow of the upper and lower probes of the rotary container, the pressure difference value between the two gas pipes is on behalf of the material thickness ratio between the upper and lower probes, and converted into the material thickness. According to the pressure difference changes it timely adjusts the gas source input volume, to obtain high measurement precision.
Description
Technical field:
The present invention relates to a kind of device of measuring material thickness in the rotary container.
Background technology:
The thickness measuring system of material thickness in the existing various measurement rotary container adopts power consumption method and noise method, and affected by environment big, measuring error is big.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, the Intellectualized pressure difference thickness measuring system for rotary container that measuring accuracy is high.
Technical solution of the present invention is:
A kind of Intellectualized pressure difference thickness measuring system for rotary container, it is characterized in that: the trailing type potential source that dynamically weighs is arranged, trailing type dynamically weigh potential source be connected with PID regulating and controlling valve that source of the gas communicates, trailing type dynamically weigh potential source by two tracheaes respectively be positioned at the upper and lower position of rotary container go up probe, probe is connected down, is equipped with orifice plate on above-mentioned two air pipe passways; First pressure difference transmitter that receives orifice plate upside pressure and following wall pressure pressure difference signal, work by PID control instrument regulating and controlling valve, produce dynamically weighing apparatus potential source, wall pressure is the change value of pressure in the reflection rotary container on the described orifice plate, described wall pressure down is the pressure in the weighing apparatus potential source, the pressure acting in conjunction of orifice plate upper and lower sides produces pressure difference on orifice plate; Weighing apparatus potential source and rotary container are followed mutually, and the potential source that dynamically weighs forms weighing apparatus stream source between orifice plate and rotary container; Between two weighing apparatus flow tubes, be connected to second pressure difference transmitter, the pressure difference between popping one's head in up and down in the rotary container during second pressure difference transmitter reflection pressure constantly changes, its information is exactly the thickness of determinand.
First pressure difference transmitter is connected on dynamically weigh orifice plate both sides between potential source and the last probe of trailing type.
The present invention is rational in infrastructure, and by the continuous fixed low-speed jet air-flows of input weighing apparatus of two probes up and down on rotary container, the pressure reduction number of degrees between two conduits have just been represented the relation of the material thickness proportion between the probe up and down, can be converted into material thickness.Can in time adjust the source of the gas input quantity according to the variation of pressure reduction, the measuring accuracy height.Be specially adapted to the fields such as measurement of coal dust layer thickness in the coal pulverizer.
