Description
Technical field
The utility model relates to concentrator, relates in particular to a kind of automatic discharge device of concentrator.
Background technology
Concentrator is based on the solid-liquid separating equipment of gravitational settling effect, is widely used in fields such as chemical industry, metallurgy, papermaking, pottery, sewage disposal.
Conventional concentrator is made up of parts such as pond, transmission device, shelf, rake, drench pit, recipient, automatic hoisting mechanism and overload indicators, the pond is drum shape, steel plate tubbing body is arranged and with two kinds of armored concrete systems, being flat shape at the bottom of the steel plate pond processed, is taper at the bottom of the cement pond processed.Behind electric motor starting, pass to worm screw by the rotation of shaft coupling drive reductor and make worm gear order about rake hour hands revolution downstream, thus the process of finishing the work.The rotating rake precipitation object with in the ore pulp gradually scrapes central authorities at the bottom of the pond, and the ore pulp after concentrating is extracted out from gape by slush pump, and the liquid of having clarified is flowed out by upper isopipe.
Precipitation object in the ore pulp is discharged from gape, but must note discharge concentration in the operating process, and sometimes because material is very dense, and deslagging is untimely, causes the concentrator overload, and dump skip is silted up, moment of torsion is crossed crooked or other device damage of ambassador's target holder.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic discharge device of concentrator in order to overcome problems such as existing concentrator discharge is untimely.The utility model is based on the existing conventional concentrator.
The utility model is provided with power of motor monitor, power comparator, programmable logic controller (PLC), air control unit and ecp and carries out valve; The input of described power of motor monitor is connected with the spindle motor of concentrator, the Monitoring Data output termination power ratio of power of motor monitor is than the input of device, the input of the enabling signal output termination programmable logic controller (PLC) of power comparator, the input of the execution switching signal output termination air control unit of programmable logic controller (PLC), the output termination ecp of air control unit is carried out valve, and ecp is carried out valve and is connected with the slag-drip opening of concentrator.
Slag-drip opening at concentrator also can be established manually-operated gate.
Described power of motor monitor is connected with spindle motor, and data monitored transferred to is attached thereto the power comparator that connects; The power comparator is delivered to programmable logic controller (PLC) with enabling signal by power ratio; After programmable logic controller (PLC) receives enabling signal, send the signal of carrying out switch to air control unit; Ecp is carried out the signal that valve is carried out air control unit, opens valve and carries out deslagging.
Described spindle motor is for can monitor power-type, with the supporting use of power of motor monitor.The signal transmission path of described automatic discharge device and being electrically connected.
Described power comparator is provided with benchmark power, and the power that obtains when the power of motor detector monitors is during more than or equal to benchmark power, and the power comparator sends enabling signal to programmable logic controller (PLC).Wherein benchmark power is that the practical production experience summary draws, with the prerequisite that prevents that dump skip silts up.
Described manually-operated gate uses when breaking down in the automatic discharge system as the backup of automatic discharge device.
Outstanding advantage of the present utility model is as follows:
1, adopting the power of motor monitor is to have utilized the power output of motor by the definite principle of load as the signal source of programmable logic controller (PLC).When the load increase, the motor moment of resistance increases, and causes that rotating speed reduces, and it is big that the speed discrepancy of rotor and rotating excitation field becomes, and causes that the input current change is big, and power of motor rises.
2, adopt the mode of power of motor monitor and power comparator, need not improve conventional concentrator again and can realize function, simple in structure.
3, adopt the control of comparator and programmable logic controller (PLC), control is simple, the reliability height, and be provided with various faults prediction scheme and treatment measures.
