Abstract
The utility model relates to an interlocking device of smelting furnaces and an electromagnetic stirrer. The interlocking device of the smelting furnaces and the electromagnetic stirrer comprises the smelting furnace, the electromagnetic stirrer and a PLC (programmable logic controller), wherein the electromagnetic stirrer is installed on a shifting frame through a lifting mechanism; the shifting frame is positioned on a slide rail and can move along the slide rail; at least one smelting furnace is arranged right above the slide rail; the electromagnetic stirrer can stir the smelting furnaces electromagnetically; and the PLC is connected with the electromagnetic stirrer and the smelting furnaces through leads. The interlocking device of the smelting furnaces and the electromagnetic stirrer is characterized in that the slide rail is at least provided with an approach switch, and the approach switches are connected with an input pin of the PLC through the leads. The interlocking device of the smelting furnaces and the electromagnetic stirrer provided by the utility model is simple in structure, easy to implement, low in cost, convenient to operate, and good and obvious in effects; one approach switch is installed on an overhauling position of the electromagnetic stirrer, and acts as a detection signal source at the position of the electromagnetic stirrer; and signals are led into the input end of the PLC through a signal wire, and the tipping control and series connection interlocking control of the smelting furnaces are realized through programs.
Description
Technical field
The utility model relates to the aluminium alloy production equipment, is specifically related to a kind of smelting furnace and magnetic stirrer interlock.
Background technology
In the aluminium production process, magnetic stirrer and smelting furnace are the equipment that two covers influence each other, cooperatively interact and use, and per two stoves are equipped with a magnetic stirrer.In process of production, magnetic stirrer has 3 positions is generally arranged, and 1 maintenance position is in the middle of two smelting furnaces, and 2 operating positions are respectively under two smelting furnaces.Be in stove bottom and rise during magnetic stirrer work, electromagnetic induction coil is pressed close to the smelting furnace bottom very much, begins energising then and stirs.In normal productive process, magnetic stirrer and smelting furnace do not have interlock function, and two complete equipments can independent operation, and so not influence each other is the situation that the smelting furnace that often occurs being tumbled when magnetic stirrer is worked under smelting furnace damages by pressure.In whipping process or magnetic stirrer when being in furnace bottom.
Summary of the invention
The utility model proposes a kind of smelting furnace and magnetic stirrer interlock to the deficiency that prior art exists.
The technical scheme of the utility model is: a kind of smelting furnace and magnetic stirrer interlock comprise smelting furnace, magnetic stirrer and PLC controller, wherein; The magnetic stirrer position is installed on the movable stand through elevating mechanism; Movable stand is positioned on the slide rail, and can move along slide rail, directly over slide rail, is provided with a smelting furnace at least; Magnetic stirrer can be to smelting furnace through the row electromagnetic agitation; The PLC controller is connected with smelting furnace with electric agitator through lead, on slide rail, is provided with one at least near switch, is connected near the input pin of switch through lead and PLC controller.
Described smelting furnace and magnetic stirrer interlock; Said PLC control system comprises the button and the relay of a PLC, some; Wherein, the 24V power supply connects the C34 supply pin of PLC, and three load button SB1, SB2, SB3 one ends connect common port B16; Other end correspondence connects input pin A3, A5, the A7 of PLC, is connected the A9 port of PLC near switch S 1; The coil correspondence of relay K A1, KA2, KA3 is connected A4, A6, the A8 output port of PLC.
Described smelting furnace and magnetic stirrer interlock, described elevating mechanism are two synchronous hydraulic cylinders or two synchronous electric push rods.
The beneficial effect of the utility model is: the utility model is simple in structure, implement easily, and cost is honest and clean, and is easy to operate, effective remarkable; The utility model is installed one near switch, as the sensed signal sources of magnetic stirrer present position on the maintenance position of magnetic stirrer.Through holding wire signal is incorporated into the input of PLC, realizes the control series connection interlocking control of tumbling of smelting furnace through program.
