Description
Technical field
The invention belongs to the technology of producing cement field, especially a kind of Controlling System for the blanking of manufacture of cement arc valve.
Background technology
Cement is important material of construction, and the mortar that water mud is made or concrete are firm durable, are widely used in engineerings such as civil construction, water conservancy, national defence.
In cement production process, the material product in the storage warehouse need be carried out the blanking discharging and transport, generally be provided with one or two feed opening on top, storing Kuku, adopt roller conveyor or machine for zipper charging; The bottom of the reservior is provided with one or more feed openings, feed opening mainly arranges according to the needs of blanking amount, each feed opening place is provided with an arc valve, open and close to select whether blanking by the control arc valve, opening and close for arc valve at present mainly is that electric motor by on the relay ac control system control arc valve rotates and reverse to realize out and close.
Adopt the mode of relay ac control system can satisfy existing requirement substantially, but hidden danger is bigger, mainly has following shortcoming: 1, most relays all are to carry out under long term wear and the weariness working condition, damage easily.And the contact of rly. is easy to generate electric arc, even can melt and produce mishandle together, causes serious consequence; 2, adopt the rly. number many, cause controlling box huge and heavy.3, as changing function or what's new, need take out stitches, wiring and even change components and parts, need cost plenty of time and man power and material to go the transformation of the way, install and debugging, cumbersome; 4, tolerance range is lower, and system is complicated, and maintenance is inconvenient.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Controlling System for the blanking of manufacture of cement arc valve, and this Controlling System is easy for installation, system stability, precision height, the convenient and long service life of maintenance.
The technical scheme that the present invention solves its technical problem employing is: a kind of Controlling System for the blanking of manufacture of cement arc valve, it is characterized in that: this Controlling System comprises that the programmable logic controller and that several arc valves, are built-in with programmodule is used for interactive man-machine interface, and man-machine interface links to each other with programmable logic controller; Programmable logic controller is provided with the output terminal of at least one group of control arc valve, the output terminal of every group of control arc valve comprises two output terminals, on the output terminal of each group control arc valve, be connected with first alternating current contactor and second alternating current contactor respectively, control rotating and reverse of electric motor on the arc valve respectively, and then the Kai Heguan of control arc valve valve; Be connected with an arc valve valve on first, second delivery port of programmable logic controller respectively and drive the limit switch of state and the limit switch of an arc valve valve off status.
Described arc valve is provided with 14, and the output terminal of corresponding control arc valve is provided with 14 groups.
Be provided with a stuff level switch for detection of high charge level in the 3rd input aperture of described programmable logic controller.
The 3rd delivery port at described programmable logic controller is connected with an emergency stop switch.
On described programmable logic controller, also be provided with two output terminals that are used for the control pilot lamp, on two output terminals for the control pilot lamp, be connected with run indicator and trouble indicating lamp respectively.
The invention has the beneficial effects as follows: 1, adopt programmable logic controller that total system is controlled, the reliability height, immunity from interference is strong; Replace a large amount of intermediate relay and the time relay with software, the only remaining a small amount of hardware relevant with input and output, and wiring reduces in a large number, and the fault that causes because of poor contact of contacts greatly reduces.2, adopt man-machine interface to carry out man-machine dialogue, replace traditional switch, longer service life with soft switch; By the program setting, can carry out electrodeless adjustablely to timing by man-machine interface, do not need to spend plenty of time and man power and material and go system is changed a social system, installs and debugs; Also can show current working state in man-machine interface simultaneously.3, each magnetic valve arranges a power switch, can select whether to enable this magnetic valve according to practical situation.
