The system has the advantages of simple structure, convenience in mounting, stability, high timing precision, long service life and humanized design; the set time can be changed through a human-machine interface; and the system can be modified, mounted and debugged with a small amount of time, a small quantity of labors and a small quantity of resources.
Description
Technical field
The utility model belongs to the technology of producing cement field, especially a kind of cement production process raw material homogenizing storehouse system that is used for.
Background technology
Cement is important material of construction, and mortar that water mud is processed or concrete are firm durable, are widely used in engineerings such as civil construction, water conservancy, national defence.
In cement production process; Need carry out homogenizing to raw material; Changing in modern times in the cement factory generally all adopts the raw material homogenizing storehouse to carry out homogenizing and storage to the bigger raw material that go out to grind of chemical component fluctuation; Make into the kiln raw ingredients all neat, thereby stablize the thermal regulation of kiln, improve the grog output and the quality of kiln.
The raw material homogenizing storehouse is to lean on the air of certain pressure that raw material are carried out homogenizing.On the plate of bottom of the reservior, install the inflation mechanism of various types, at first make material loosening after the inflation, make it fluidization then and then stir, make raw ingredients even.Since the difference of inflation mechanism with arrange different, cause different homogenization process and multi-form raw material homogenizing storehouse.Mainly select which zone inflation through the keying of timing control SV at present, does not inflate in which zone, to reach the effect of homogenizing.
Adopt relay control mode can satisfy existing requirement basically, but have following problem: 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.Under the situation of full load delivery, rly. will produce a large amount of heat and noise, also consume a large amount of electric energy simultaneously; 3, relay control system must be manual wiring, installation, if simple change is arranged, also need spend plenty of time and man power and material and go the transformation of the way, installs and debugging; 4, tolerance range is lower, and timing can not be electrodeless adjustable.
Summary of the invention
The technical problem that the utility model will solve provides a kind of manufacture of cement raw material homogenizing storehouse bottom of the reservior ventilating control system that is used for, and this system is simple in structure, and is easy for installation, system stability, and timing accuracy is high, and long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of manufacture of cement raw material homogenizing storehouse bottom of the reservior ventilating control system that is used for; Comprise the inflation mechanism that is installed in raw material homogenizing storehouse bottom of the reservior; Be connected through pipeline between the said inflation mechanism; On the gas ducting of correspondence, be provided with SV; It is characterized in that: this system also comprises a programmable logic controller, and programmable logic controller is provided with the output terminal that connects one to one with said each SV and on each output terminal, is connected with an intermediate relay respectively, and the normally opened contact of intermediate relay is connected with the control coil of said SV.
Said programmable logic controller also is connected with the transfer lever of a manual control, and the manual one to one control input end of SV is connected with a manual switching push button of controlling under on programmable logic controller, being provided with on each manual control input end.
The control coil of said each SV links to each other with a power switch.
Said programmable logic controller is provided with the output terminal of two run indicator, and the output terminal of one of them run indicator is connected with automatic run indicator, and the output terminal of another run indicator is connected with manual run indicator.
Also be connected with one on the said programmable logic controller and be used for interactive man-machine interface.
The beneficial effect of the utility model is: 1, adopt programmable logic controller that total system is controlled, safety is high, and immunity from interference is strong; Replace a large amount of intermediate relay and the time relay with software, the only remaining little hardware relevant with import and export, 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 conventional switch, longer service life with soft switch; Through the program setting, can carry out electrodeless adjustablely to timing through man-machine interface, need not spend plenty of time and man power and material and go system is changed a social system, installs and debugs; Also can on man-machine interface, show current working state simultaneously.3, each SV is provided with a power switch, can select whether to launch this SV according to practical situation.
