Description
Technical field
The utility model relates to a kind of automatic sampler, relates in particular to a kind of liquid automatic sampler that mine tailing pulp-water mine-containing amount detects that is used for.
Background technology
In mining industry is produced, especially for the mine tailing exploitation, need be by taking a sample detection to determine the grade of mine tailing to containing the iron waste water ore pulp.Existing sampling method is divided into two kinds of hand sampling and mechanical samplings, there is inaccurate, the inaccurate defective of sample amount sample time in the former, be difficult to guarantee the accuracy of analysis data, the latter uses the work of driven by motor sampler, but adopt integrated chip control, the time interval is adjusted inconvenient, failure rate height under the more rugged surroundings of dust more, maintenance difficulty is big, poor practicability.
The utility model content
The technical problems to be solved in the utility model is: design that a kind of circuit is simple, reliable operation, sample time are adjusted easily, easy to maintenance, can be at the automatic sampler of permanently effective work under the rugged environment.
The technical solution of the utility model is: a kind of automatic sampler, comprise motor, sampling head and electric control circuit, it is characterized in that, described electric control circuit is by near switch S B1, starting switch SB2, contactor KM, auxiliary reclay KA1, auxiliary reclay KA2, sensor SQ and time relay KT form, automatic sampler power supply phase line is at first passed through near being divided into two-way behind the switch S B1, the first via is through starting switch SB2, get back to power ground behind the coil of auxiliary reclay KA1, the self-sustaining normal opened contact KA1a of auxiliary reclay KA1 is connected in parallel on the starting switch two ends; The second the tunnel gets back to power ground through being further divided into three the tunnel, the one tunnel behind the normal opened contact KA1b of auxiliary reclay KA1 behind sensor SQ, auxiliary reclay KA2 coil; Power ground is got back in another road behind time relay KT contact, auxiliary reclay KA2 normally closed contact, contactor KM coil, the self-sustaining normal opened contact of contactor KM is connected in parallel on time relay KT contact two ends; Third Road is got back to power ground behind the normally closed contact of contactor KM, time relay KT coil.
The utility model has following advantage compared with the prior art:
1, simple, the reliable operation, easy to maintenance of the utility model circuit.
2, the utility model has been owing to adopted time relay control sample time, and is easy to adjust.
3, the electrical equipment work of the utility model employing is not subjected to the influence of mine tailing dust, can permanently effective work under rugged environment.
Description of drawings
Fig. 1 is an electric control circuit schematic diagram of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 1 electric control circuit schematic diagram of the present utility model, electric control circuit is by forming near switch S B1, starting switch SB2, contactor KM, auxiliary reclay KA1, auxiliary reclay KA2, sensor SQ and time relay KT, automatic sampler power supply phase line L at first passes through near being divided into two-way behind the switch S B1, the first via is got back to power ground N behind the coil of starting switch SB2, auxiliary reclay KA1, the self-sustaining normal opened contact KA1a of a starting switch two ends auxiliary reclay KA1 in parallel; The second the tunnel is further divided into three the tunnel behind the normal opened contact KA1b of auxiliary reclay KA1, the first via is got back to power ground N behind sensor SQ, auxiliary reclay KA2 coil; The second the tunnel gets back to power ground N behind time relay KT contact, auxiliary reclay KA2 normally closed contact, contactor KM coil, the self-sustaining normal opened contact of a time relay KT contact two ends contactor KM in parallel; Third Road is got back to power ground N behind the normally closed contact of contactor KM, time relay KT coil.
The workflow of automatic sampler is as follows: press starting switch SB2, the coil of auxiliary reclay KA1 is charged, its self-sustaining contact KA1a adhesive, the same adhesive of another normal opened contact KA1b, time relay KT coil is charged after setting the sample interval time-delay by the normally closed contact of contactor KM, and contactor KM coil powers on through time relay KT contact, auxiliary reclay KA2 normally closed contact, its self-sustaining normal opened contact closure, electric motor starting drives sampler and starts working.After finishing once sampling, the sensor SQ closing of contact, auxiliary reclay KA2 coil is charged, its normally closed contact disconnects, contactor KM coil losing electricity, the motor stall, sampler stops sampling, this moment contactor KM the normally closed contact closure, time relay KT coil trigger, behind the sample interval that arrival is set, time relay KT coil motion, its normal opened contact closure, contactor KM coil is through time relay KT contact, auxiliary reclay KA2 normally closed contact powers on once more, its self-sustaining normal opened contact closure, electric motor starting, drive sampler and restart work, carry out so repeatedly.When disconnecting near switch S B1, the electric control loop outage, till pressing starting switch SB2 once more, system can re-power.
The liquid mine pulp sampling that the utility model can be widely used in mining firm detects, and also can be used for the equipment of other automatic samplers or the work of similar periodicity power on/off separately.
