Abstract
The invention relates to an integrated mass concentration online detection method for high-concentration ore pulp, and belongs to the field of high-concentration heavy metal concentration metering. The technological process of the method comprises the following steps of: adopting an integrated technological mode, and utilizing a radar location instrument to be matched with a Parshall flume to cooperate so as to complete the flow metering of an open channel; and adopting a Krohne densimeter and an SPX peristaltic pump to match with each other so as to realize random concentration mass and concentration detection. The method is used for metering the ore pulp and guiding the tailings concentration control in an ore dressing process, so that a problem that online flow, concentration and density detection cannot be carried out on high-concentration fluid without radioactive sources is solved. The methods for metering high-concentration heavy metals are widened, and the method has good application and popularization prospects.
Description
Technical field
The present invention relates to a kind of high-concentration ore slurry mass concentration and be integrated in line detecting method, belong to mining and metallurgy specialty metering detection technique.
Background technology
Dense (close) degree meter, for the online detection of industrial process material density, concentration, is obtained the density of material to gamma-ray principle of absorption according to material online, then by the concentration of density calculation out-feed liquid or the proportioning of two kinds of compositions.Dense (close) degree meter all adopts radioactive source online, except expensive, also need put on record in the Ministry of Public Security.From factors such as safety, management, consider, the existence of radioactive source has restricted its applying in the mining industry industry.And nowadays automatic, the extensive application of intellectualized technology in the mining and metallurgy production procedure, to the control of ore pulp or mine tailing quality, the dense granularity more strict requirement of having withdrawn deposit.
Existing dense (density) detector, be subject to the restriction of safety and price, is difficult to large scale application, particularly in the mining industry industry, applies, and therefore seeks a kind of high concentration mass concentration detection method that does not rely on radioactive source, has important practical significance.
Summary of the invention
Target of the present invention is to provide a kind of online random quick high-concentration ore slurry mass concentration integrated testing method that detects, and can be to greatest extent for the robotization of mineral processing circuit, intelligent online dense degree detect, provides economic, applicable, convenient, safety, easy technical support.
Solving technical matters of the present invention realizes by following technical scheme: establish Bashel groove (Parshall flume) on the ore pulp open channel, adopt the radar locating instrument to coordinate the associated working of Bashel groove to complete open-channel flow measurement; Adopt Cologne densitometer and peristaltic pump to coordinate, grab sample detects concentration quality and the concentration of ore pulp open channel.
Adopt radar locating instrument and electromagnetic flowmeter associated working to complete open channel, pipeline flow metering; The radar locating instrument is connected with the PLC interface by data line respectively with the Cologne densitometer.
The sampling pulp density or tailings concentration 25～85%, flow 1～500m
3/ h.
The invention has the beneficial effects as follows: adopt described Cologne densitometer, radar locating instrument, Bashel groove and peristaltic pump that the collection in worksite signal is sent to pulpit, thereby reached discharging the time suitable monitoring of dense degree, solved except radioactive source, existing instrument can't detect online to the high concentration fluid difficult problem of flow, dense degree, to accelerate implementing mineral processing circuit robotization, intelligent online dense degree, detecting economic, applicable, convenient, safety, easy technical support are provided.
With existing various existing mining and metallurgy specialty measurement technologies, compare, the present invention does not have radiological hazard fully, can carry out remote visual grab sample, and mineral slurry flux, quality, concentration directly show, ore pulp can be according to the need of production random sampling, avoids ore pulp for a long time to the impact wear of electronic scale.
The accompanying drawing explanation
Fig. 1 is principle process chart of the present invention
.
Embodiment
Referring to Fig. 1, adopt a Cologne densitometer OPTIMASS1300-S15(DN25 PN40 220VAC power supply, 4-20mA output) coordinate with the SPX peristaltic pump and carry out dense degree detection; On the densimeter measurement pipeline, the MP034 electrical ball valve has been installed, by PLC, control, realize the automatic cleaning of density measurement system input, excision and pipeline.
On-the-spot PLC cabinet and the touch-screen (being integrated in PLC cashier's office in a shop) installed, the radar locating instrument is connected with the PLC interface by data line respectively with the Cologne densitometer, carries out collection, processing, the demonstration of the data such as mineral slurry flux and concentration; Data are by the optical fiber teletransmission to the remote terminal that is arranged on control room, and the dispatcher can monitor mine tailing flow and concentration of emission at any time, and the condition of production is carried out to rational management; On-the-spot PLC cabinet and motorized valve power supply draw the pumping plant outside ore pulp open channel tunnel, and the data communication optical cable is applied to control room along near communication line.
The panel switches of native system are that in System cabine, (from left to right) first two-phase isolating switch is the system total power switch, second power switch that the two-phase isolating switch is disposal system, the 3rd two-phase switch is the instrument of other DC24V power supply and the power switch of touch screen.
That in system, start that cause first determines connecting system is AC220V, the 50HZ two-phase alternating current, when closing isolating switch because of first close (from left to right) first, if do not have abnormal occurrence just can close second and the 3rd isolating switch after closing.If the abnormal occurrence of burst is arranged because disconnecting immediately first isolating switch at the system operational process, if will carry out power down process to system when system is normally moved, should first disconnect second and the 3rd isolating switch and then disconnect first isolating switch.When electric power system can work, just can push the switch on S7-200 CPU the position of RUN, at this moment system just can be carried out data and processed.Should first push the STOP position to this switch before each system cut-off, after emergency-off, also should push this switch on the STOP position.
