Abstract
The utility model provides a kind of liquid level emasuring device to comprise the ball float contacting with testing liquid is set, and signal conversion module, is characterized in that, also comprises the cantilever that connects described ball float and signal conversion module, and described cantilever is that non-flexible material is made.Cantilever by an inflexibility is connected with ball float, can measure real-time and accurately the liquid level of liquid, and can not affect because of silt the degree of accuracy of liquid level emasuring device.
Description
Technical field
The utility model relates to the technical field of level gauging, relates in particular to a kind of liquid level emasuring device being applied in generating plant slag removing system.
Background technology
In generating plant slag removal equipment, be conventionally all provided with sewage disposal system, in prior art, conventionally adopt plug-in type fluid level measuring gauge to measure the liquid level of sewage, the principle of work of this liquid-level type meter is: the proportional principle of height based on surveyed fluid pressure to this liquid, static pressure is converted to electric signal, pass through again temperature compensation and linear revise, change into standard electric signal.
But in sewage disposal system, because the husky mud suspending in sewage is more, the liquid level gauge that so just causes putting in sewage is often covered by the mud of bottom settlings, so measurement result is inaccurate.
In order to solve plug-in type liquid level gauge because silt causes the inaccurate technical matters of measurement result, a kind of settling mode is for adopting the contactless liquid level gauges such as ultrasound wave to measure, if but the mode of employing ultrasonic measurement, again because the higher easy generation water vapor of sewage temperature, so liquid level meter probes place easily discloses, measurement result is also not accurate enough, and ultrasonic measurement also exists the problem that equipment is large, expense is high.
Meter while also having a kind of floating-ball level switch, although can solve above the deficiencies that two kinds of liquid level gauges exist, can only send liquid level the highest with two measured values of minimum point, can not measure in real time the height of liquid level.
Utility model content
The above-mentioned technical matters existing in order to solve meter in prior art, the utility model provide a kind of can be in real time, the liquid level emasuring device of Measurement accuracy sewage quantity.
A kind of liquid level emasuring device that the utility model provides comprises the ball float that setting contacts with testing liquid, and signal conversion module, is characterized in that, also comprises the cantilever that connects described ball float and signal conversion module, and described cantilever is that non-flexible material is made.
Preferably, above-mentioned signal conversion module comprises the slide rheostat being connected with above-mentioned cantilever.
Preferably, above-mentioned signal conversion module is also provided with the inner conductors connecting in slide rheostat, send element with the change being connected with inner conductors.
Preferably, above-mentioned signal conversion module also comprises the pipeline that wraps up inner conductors, and the flange being connected with described pipeline.
Adopt technique scheme, be connected with ball float by the cantilever of an inflexibility, can measure real-time and accurately the liquid level of liquid, and can not affect because of silt the degree of accuracy of liquid level emasuring device.By slide rheostat, can convert the movement of liquid level change information bronze drum cantilever to electric signal, more convenient liquid level information is passed to outside control center.Further, by flange, liquid level emasuring device can be fixedly mounted on to outside, avoid the wire of existing plug-in type liquid level gauge to twine the risk on rotary machine.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of liquid level emasuring device of relating to of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it should be noted that, these specific descriptions just allow those of ordinary skill in the art be more prone to, clearly understand the utility model, but not to limited explanation of the present utility model.
Embodiment
As Fig. 1, preferably, the present embodiment provides a kind of liquid level emasuring device 1 to comprise the ball float 3 that is arranged on sewage (liquid level) 2 tops, and the cantilever 4 being connected with ball float 3, and cantilever 4 other ends are connected with signal conversion module.Signal conversion module comprises that a slide rheostat (R) 5 connects, and cantilever 4 is made for flexible material, such as the higher material of the hardness such as steel, alloy, in sewerage, sewage level changes like this, can directly drive the movement of slide rheostat 5 by cantilever 4, the variation of the resistance by slide rheostat 5 detects the variation of liquid level in sewerage in real time.Preferably, cantilever 4 surfaces are antirust, corrosion-resistant material in addition, such as paint.
Preferably, signal conversion module also comprises an inner conductors 6 being connected with slide rheostat 5, inner conductors 6 is also connected to a signal transmitting element 9, signal transmitting element 9 can be by the signal of slide rheostat 5 through linear revise, change into standard electric signal, can directly be passed to outside control center or display unit.
Preferably, liquid level emasuring device 1 also comprises the pipeline 7 of parcel inner conductors, and the flange 8 being connected with described pipeline; Can pass through like this flange, liquid level emasuring device is fixedly mounted on to outside, avoid the wire of existing plug-in type liquid level gauge to twine the risk on rotary machine.
Adopt the preferred technical scheme of the present embodiment, can have following beneficial effect: 1, ball float cantilever metering system is more accurate; 2, liquid level emasuring device fixed installation, the risk of avoiding that liquid level gauge occurs and twining rotary machine; 3, ball float cantilever metering system strong adaptability, is widely used; 4, variation that can real time monitoring liquid level, measures blind area little; 5, equipment dependability is high, and maintenance is little, can ensure the normal input of liquid level control interlock circuit.
Finally it should be noted that, above-mentioned explanation is only most preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction.Any those of ordinary skill in the art; do not departing within the scope of technical solutions of the utility model; all can utilize way and the technology contents of above-mentioned announcement to make many possible variations and simple replacement etc. to technical solutions of the utility model, these all belong to the scope of technical solutions of the utility model protection.
