Description
Technical field
The present invention relates to a kind of liquid level detection device, the real-time online that is specially adapted to the tank level in Emulsion Explosive Production detects.
Background technology
In the production of emulsion explosive, in order to guarantee the security of the continuity of producing and production, the accurate detection of tank level is seemed to particularly important.Due to stirrer and heating coil being arranged in storage tank, the operating mode complexity, medium temperature is high in addition, and many liquid level instruments are difficult to be competent at, thereby the mode that we have selected radar level gauge to add waveguide pipe detects liquid level.But detect the demand that effect can not meet production, low precision usually occurs, the phenomenon of false liquid level even occurs.By analysis, low precision is to be caused by the bubble in medium or suspension, and false liquid level is (as adopted guided wave radar, on the guided wave bar, bridging also can produce deceptive information) of being caused in the bridging of waveguide pipe inwall by the suspension in medium.
Chinese patent application 200910145595.9 discloses a kind of liquid storage tank liquid-level meter, comprising: float, runner, stay cord, motor, power sensor, elastomeric element and pedestal; Wherein, the rotating shaft of motor connects runner, and the runner outer felt is wound with stay cord, and float hangs on stay cord; The first end of power sensor is fixedly connected with motor; The second end of the first end of elastomeric element and pedestal is fixedly connected with the power sensor, and the second end of elastomeric element is fixedly connected with the first end of pedestal.But it is the detection under quiescent conditions that this liquid storage tank liquid-level meter only is suitable for liquid in storage tank, can't detect online for the real-time high-precision of the tank level of the production of emulsion explosive.
Summary of the invention
Purpose of the present invention is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to maintenance, can guarantee the real time on-line detection device of tank level in the Emulsion Explosive Production of anti-bridging Anti-bubble of measuring accuracy.
For reaching above-mentioned task of the present invention, in a kind of Emulsion Explosive Production of the present invention, the real time on-line detection device of tank level is by the following technical solutions:
The real time on-line detection device of tank level in a kind of Emulsion Explosive Production of the present invention, it comprises radar level gauge, waveguide pipe, described radar level gauge is arranged on the upper end of waveguide pipe, and the size of the loudspeaker of the internal diameter of described waveguide pipe and radar level gauge bottom is complementary; Described waveguide pipe is for being metal material, and it is good selecting stainless-steel tube, and the waveguide pipe inner wall smooth is without burr; The top of waveguide pipe have one or several for balance pipe in the air hole of outer boundary, the position of described air hole on waveguide pipe is higher than the higher limit of liquid level; Lower end in waveguide pipe is sealed by a sheet metal, and described sheet metal central authorities leave the inflow and outflow square hole of measured medium, a pair of guide groove of welding below described sheet metal, and described guide groove is installed screen pack, and described screen pack is metal material; The size of guide groove and screen pack is complementary, and is fixed after assurance screen pack insertion guide groove.
Described waveguide pipe internal diameter is that 50 ~ 100mm is advisable.
In a kind of Emulsion Explosive Production of the present invention, the real time on-line detection device of tank level is because its waveguide pipe only has the unique feed inlet and outlet in lower end, and installed screen pack additional, make suspension and bubble in medium not enter waveguide pipe, thereby guaranteed the precision that liquid level detects.The structure of pick-up unit makes screen pack have self-cleaning function and long service life, safeguards the characteristics such as simple.
After in a kind of Emulsion Explosive Production of the present invention, the real time on-line detection device of tank level adopts technique scheme, has following beneficial effect: solved the problems such as bridging during liquid level detects, guarantee the online precision that detects in real time of liquid level, met the requirement of Emulsion Explosive Production.This device has the characteristics such as processing is simple, and expense is low, and working service is convenient.
