Abstract
A novel liquid level meter is provided, which is characterized in: the novel liquid level meter comprises an air compressor, a gas tube, and a cracker tube, wherein, one end of the gas tube is connected to the cracker tube that is open to the other end of the gas tube, a flow controller is arranged on the gas tube, and a micro-differential pressure transmitter is provided on the cracker tube.
Description
Technical field
The utility model relates to a kind of liquid level gauge of measuring liquid level, particularly a kind of novel liquid level meter of measuring glass metal liquid level in the glass furnace.
Background technology
In the production of glass fibre, it is the most key operation that glass metal melts system, extremely important as the liquid level control of one of kiln control three elements, if liquid level meeting on the low side causes the wire-drawing operation difficulty, influences output and product quality; If liquid level is higher, then can cause glass temperature wayward, increase the kiln burden, influence product quality.Tank level control system is by liquid level gauge the liquid level signal that records to be passed to DCS, through default definite value relatively after, DCS output control signal is arranged, control the rate of feeding of batch charger, realize sluggish adjusting of tandem with batch charger.Comparatively advanced at present liquid level gauge is the nucleon liquid level indicator, but this nucleon liquid level indicator not only comparatively complicated but also its radioactive source that adopts of structure is a caesium-137, careless manipulation very easily causes irreversible radiation damage to human body, so its cost of safeguarding, adjusting is very high, has very big potential safety hazard.
Summary of the invention
The purpose of this utility model just is to provide a kind of liquid level gauge simple in structure, easy to maintenance.
Its technical solution is as follows:
A kind of novel liquid level meter, it includes air compressor, gas pipe line and bubbling pipe, and described gas pipe line one end is communicated with the gas pipe line other end and is communicated with bubbling pipe, and described gas pipe line is provided with flow quantity control instrument, and bubbling pipe is furnished with differential pressure transmitter.
The utility model in use, the outlet side of bubbling pipe is inserted in the glass metal, keep the gas flow in the bubbling pipe constant by flow quantity control instrument, according to formula P=ρ gh, P liquid internal pressure, ρ is a fluid density, g is a constant, is the distance from the measured point to the liquid level, in the identical liquid of density, then the size of P is directly proportional with the size of h, can determine h as long as promptly record the concrete numerical value of P.When the pressure of bubbling pipe inner outlet is a bit larger tham the pressure of glass metal inside, gas will be flowed out by the bubbling pipe outlet, the interior pressure of bubbling pipe this moment can be approximately equal to the pressure of this glass metal of selecting, if stationkeeping with bubbling pipe, and gas flow is constant in the maintenance pipeline, then working as liquid level changes, gas pressure intensity in the pipeline will change along with the liquid level height, can detect thus that the variation of gas pressure intensity obtains liquid level change in the pipeline by differential pressure transmitter, control the rate of feeding of stove according to above-mentioned liquid level change.The beneficial effects of the utility model are to obtain indirectly by the variation of measuring certain some pressure in the glass metal variable quantity of liquid level, thereby the rate of feeding of control stove batch charger is simple in structure and be easy to maintenance, has saved the operation and maintenance cost greatly.
As improvement of the present utility model, above-mentioned bubbling pipe and differential pressure transmitter pipeline are provided with the buffering gas tank, and described cushion gas canister incoming gas mouth is communicated with bubbling pipe, and the gas outlet is communicated with differential pressure transmitter.Because the pipeline caliber that the utility model adopted is thinner, when by gas flow, underfed causes the manifold pressure fluctuation apparent in view, disturb the work of differential pressure transmitter, influence measuring accuracy, after installing above-mentioned buffering gas tank additional, can make the fluctuation of the interior gaseous tension of pipeline tend towards stability, increase the measuring accuracy of differential pressure transmitter.
Below in conjunction with accompanying drawing the utility model is done further description:
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model consists predominantly of air compressor 1, gas pipe line 2 and bubbling pipe 3, described gas pipe line 2 one ends are communicated with air compressor 1 other end and are communicated with bubbling pipe 3, and described gas pipe line 1 is provided with flow quantity control instrument 4, and bubbling pipe is furnished with differential pressure transmitter 5.Above-mentioned bubbling pipe 3 and differential pressure transmitter 5 pipelines are provided with buffering gas tank 6, and buffering gas tank 6 air intake openings are communicated with bubbling pipe 3, and the gas outlet is communicated with differential pressure transmitter 5.During use, keep the air mass flow in the bubbling pipe 3 constant by flow quantity control instrument, differential pressure transmitter 5 can be monitored the pressure change in the bubbling pipe 3 in real time, and compares with setting value, thereby the rate of feeding in the control stove, the constant height of metal level in the maintenance stove.
Above-mentioned air compressor 1, flow quantity control instrument 4 and differential pressure transmitter 5 all can adopt or use for reference prior art, influence the quality of glass metal for preventing that foreign gas and glass metal react in the air, and pressure gas can adopt nitrogen or other inert gases.
