Technical field
The present invention relates to a kind of pick-up unit, particularly relate to a kind of pick-up unit of pipeline flow signal.
Background technology
The monitoring that flow had or not when industry spot was to pipeline transmission slag slurry material at present lacks simple and reliable detection means.Because the high precipitability of slag slurry material and the undulatory property of the water cut of material own; The sensor of conventional contact class flow detector is placed on this environment under and can be very soon lost efficacy by sediment obstruction or corrosion, and conventional noncontact class flow detector costs an arm and a leg, to the environmental requirement height of industry spot; And there is a large amount of electromagnetic interference (EMI) in actual industry spot; Noise, dust and irregular oscillation, conventional with this understanding noncontact class flow detector is also powerless.On-the-spot control system and the idle running of slag stock pump protection also require to collect at least the switching value signal (promptly having or not) of slag slurry flow, so that implement the integral body control and the protection production equipment of non-blind area.
Summary of the invention
The object of the present invention is to provide a kind of pick-up unit of pipeline flow signal; In order to collect the switching value signal of slag slurry flow; This device can be under abominable industry spot environment; Collect having or not of slag slurry flow simple and reliablely, pipe shape and length of straight pipe are not had any restriction, can be useful in the application scenario of different moisture content simultaneously again.
The objective of the invention is to realize through following technical scheme:
A kind of pick-up unit of pipeline flow signal; Include gas generator, gas delivery conduit, pipeline, outlet pump, gas concentration sensor, signal Processing and output unit; The pick-up unit of its said a kind of pipeline flow signal is set up gas detection signals at the material input, the output terminal that flow; Gas generator is connected with gas delivery conduit and pipeline, and gas concentration sensor is arranged at by the outlet pump, and gas concentration sensor is connected with signal Processing and output unit.
The pick-up unit of described a kind of pipeline flow signal; Its described gas generator and gas concentration sensor are pick-up unit independently; At the gas concentration sensor that pipeline exit is placed, signal processing circuit output services signal is connected with main control unit or actuator.
The pick-up unit of described a kind of pipeline flow signal, its described gas generator gas places pipeline, and gas generator, gas concentration sensor, signal processing circuit and corresponding output unit are formed detecting unit.
Advantage of the present invention and effect are:
1. the present invention can detect the switching value signal of slag slurry flow simple and reliablely, has enlarged the monitoring range of automatic control system, has reduced the maintenance cost of equipment.

3. the present invention is through detecting the concentration of specific gas at pipeline exit; At the additional simple additional gas detection signal of the material input end that flows; Characterize the switching value of mobile material then in the characteristic of output terminal detection additional gas detection signal; Carry the independent detection device of gas generator and gas concentration sensor, be applicable to that all pipeline transportation materials are to close in the field of containing slag slurry impurity.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present invention;
Fig. 2 is that the side of the pipeline among Fig. 1 when flow is arranged cutd open synoptic diagram.
Embodiment
With reference to the accompanying drawings the present invention is elaborated.
Among the figure: 1 gas generator, 2 gas delivery conduit, 3 pipelines, 4 outlet pumps, 5 gas concentration sensors, 6 signal Processing and output unit, 7 slag slurry materials.
In Fig. 1; The certain density gas that gas generator 1 produces is injected in the pipeline 3 through gas delivery conduit 2; Be arranged near the outlet pump 4 gas concentration sensors 5 and detect in real time gas concentration and signal is delivered to signal Processing and output unit 6 is handled, accomplish the output of flow signal.
In Fig. 2; When in the pipeline 3 during the slag slurry Flow of Goods and Materials; The certain density gas that produces by gas generator 1 through gas delivery conduit 2 by all or part of being dissolved in the slag slurry material 7 in real time; The concentration that is positioned near the detected gas that is produced by gas generator 1 of the gas concentration sensor 5 outlet pump 4 is lower than pre-set threshold, and output has flow signal to give main control unit or actuator after signal processing circuit.
When not having the slag slurry Flow of Goods and Materials in the pipeline 3; The certain density gas that is produced by gas generator 1 is transmitted to outlet pump 4 along pipeline 3 through gas delivery conduit 2; The concentration that is positioned near the detected gas that is produced by gas generator 1 of the gas concentration sensor 5 outlet pump 4 is more than or equal to pre-set threshold, and the no flow signal of output is to main control unit or actuator after signal processing circuit.
It is in the flow signal monitoring of material that the present invention is applied in the slag slurry, is suitable for exporting the fields such as idle running protection and control system Centralized Monitoring of pump.Through at the additional simple additional gas detection signal of the material input end that flows, characterize the switching value of mobile material then in the characteristic of output terminal detection additional gas detection signal.The present invention is suitable for exporting fields such as idle running protection and the control system Centralized Monitoring of pump.
Gas generator of the present invention produces in the certain density gas delivery inlet pipe road; If there is the Dual-Phrase Distribution of Gas olid body flowing in the pipeline; Then this gas incorporates in the fluid; The detected gas concentration of gas concentration sensor of placing at pipeline exit does not reach pre-set threshold, and the signal of output operate as normal is given main control unit or actuator after signal processing circuit, if there is not the Dual-Phrase Distribution of Gas olid body flowing in the pipeline; This gas flow pipe outlet then; The detected gas concentration of gas concentration sensor of placing at pipeline exit reaches pre-set threshold, and the out-of-work signal of output is given main control unit or actuator after signal processing circuit, has also just reached the idle running protection purpose of outlet pump.Carry the independent detection device of gas generator and gas concentration sensor.Be applicable to that all pipeline transportation materials are to close in the field of containing slag slurry impurity.The variation of corresponding gas concentration is handled and is obtained corresponding switch controlling signal when having or not the slag slurry material in pipeline, to flow through detection.Detect the concentration of specific gas at pipeline exit.
