Abstract
The utility model relates to the field of clarification pool liquid-level control technology, especially a clarification pool liquid-level alarm device. On the pumping station warning water level of the clarification pool is disposed a liquid-level switch, which is connected with a sound-light alarm disposed in the motor transmission chamber through a switch signal wire, and connected with a PLC control device disposed in the control chamber. When the liquid reaches the warning water level, the liquid-level switch can be activated to send the switch signal and the sound-light alarm in the motor transmission chamber can be also activated. When the liquid is below the warning water level, the liquid-level switch can be reset and send a reset signal to observe the liquid level of the clarification pool effectively. By modifying the PLC ladder diagram, the point can be changed to a signal, which allows the activation of the standby water pump motor, when the liquid is below the warning water level, and sign an alarm on the resistance state diagram. The utility model has the advantages of reducing the suspended production caused by the motor burning damage in the motor transmission chamber, observing and dealing with the problem of water level exceeding limit to prevent the accidents.
Description
Technical field
The utility model relates to clarifying basin liquid level control technology field, particularly a kind of liquid level alarm device of clarifying basin.
Background technology
At present, pump station of recirculation water 29m clarifying basin liquid level and pump house ground level are at a distance of extremely near.Ring pump works clarifying basin post worker leans on naked eyes fully to the monitoring of liquid level now.When the liquid level of clarifying basin rises rapidly, cause the recirculated water in the clarifying basin to overflow, the activity in production in ore dressing plant has been caused seriously influence.
Summary of the invention
The utility model provides a kind of liquid level alarm device of clarifying basin.Avoid since between turn(a)round or the backwater amount excessive, cause liquid level to rise rapidly, cause and handle untimely and cause the stirring motor in the pump house to be taken place by the accident of water logging scaling loss.
The purpose of this utility model realizes by following technical proposals:
The liquid level alarm device of clarifying basin of the present utility model, it is characterized in that level switch is installed at pump house warning line place in clarifying basin, this level switch is connected by the switching value signal wire audible-visual annunciator indoor with being arranged on drive of motor, and is connected with PLC control device in being arranged on the pulpit.
When liquid level arrives warning line, touch level switch and send the switching value signal, trigger the indoor audible-visual annunciator of drive of motor, prompting post workman carries out emergency treatment, starts stand-by pump, adds high throughput, prevents that liquid level from rising rapidly; When liquid level was lower than warning line, level switch resetted, and sent reset signal, and its auxiliary post worker is effectively monitored the clarifying basin liquid level.The contact of correspondence is inserted in the production control system in workshop, the ladder diagram of PLC is made corresponding modification, this point is arranged to remain the permission signal that the reserve pump motor starts simultaneously, and on resistance state figure, make prompting and report to the police
The beneficial effects of the utility model are: can reduce the stopping production that drive of motor indoor motor scaling loss causes, in time find to handle the problem that water level transfinites, prevent because the accident that motor burning causes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the given embodiment of accompanying drawing, further specify embodiment of the present utility model.
As shown in Figure 1, the liquid level alarm device of clarifying basin of the present utility model, it is characterized in that level switch 5 is installed at pump house warning line place in clarifying basin 1, this level switch 5 is connected with audible-visual annunciator in being arranged on drive of motor chamber 2 by the switching value signal wire, and is connected with PLC control device in being arranged on pulpit 3.4 is motor among the figure.
When liquid level arrives warning line, touch level switch 5 and send the switching value signal, trigger the indoor audible-visual annunciator of drive of motor, prompting post workman carries out emergency treatment, starts stand-by pump, adds high throughput, prevents that liquid level from rising rapidly; When liquid level was lower than warning line, level switch resetted, and sent reset signal, and its auxiliary post worker is effectively monitored the clarifying basin liquid level.The contact of correspondence is inserted in the production control system in workshop, the ladder diagram of PLC is made corresponding modification, this point is arranged to remain the permission signal that the reserve pump motor starts simultaneously, and on resistance state figure, make prompting and report to the police.
The beneficial effects of the utility model are: can reduce the stopping production that motor-driven indoor motor 4 scaling loss cause, in time find to process the problem that water level transfinites, prevent because the accident that motor 4 scaling loss cause.
