Abstract
The utility model relates to a time delay protection device, which belongs to the field of production automation. A time delay protection device of an air locking valve for COREX vertical mill comprises a mill main motor (1) of COREX vertical mill and a plurality of air locking valve motors (2) on the grinding portion, and is characterized in that motor work sensors (3) are respectively mounted on the air locking valve motors (2), each sensor (3) is respectively connected with a time delay protection controller, the time delay protection controller comprises a signal source detection module connected with each sensor (3), the signal source is connected with a judging module after detecting a module, and is respectively connected with a main motor control module of a mill and a timing unit after judging a module, a comparison module is arranged in the timing unit, and is connected with the signal source detection module, and the main motor control module of the mill is connected with the power supply control loop of the mill main motor (1). The time delay protection device enables a vertical mill to continuously produce, reduces the frequent starting of the vertical mill, and is beneficial for prolonging the service span of the vertical mill.
Description
Technical field
The utility model relates to a kind of delay protection device, relates in particular to a kind of delay protection device that is used to protect the air valve of COREX Vertical Mill.
Background technology
In COREX Vertical Mill production process; two air valves that go out the mill place are easy to putty occur and situation about tripping; after generally all setting the air valve tripping operation now grinding machine master motor is carried out automatic trip, thereby protection, air valve tripping operation causing loop has influence on grinding machine master motor because changing.After the air valve tripping operation, can clear up, Vertical Mill is resumed production fast air valve.Process is to the analysis and the investigation of actual conditions in the practice, discovery air valve putty can be cleaned out very soon, need the time of processing not long, just can reply normal in short time, and the tripping operation of air valve can not influence the discharging circulation of grinding machine at short notice, can not cause in the grinding machine the various consequences that are unfavorable for Vertical Mill such as putty yet.
Yet with present system, there is a tripping operation will cause the automatic trip of grinding machine master motor in two air valves, such default makes the tripping operation of winner's motor frequent, and the equipment that makes is frequently closed down startup, is unfavorable for producing and easily shortening continuously the service life of equipment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of air valve delay protection device of the COREX of being used for Vertical Mill, solves the defective that prior art has influenced continuous production and shortened the service life of equipment.
Technical scheme
A kind of air valve delay protection device that is used for the COREX Vertical Mill; the grinding machine master motor 1 that comprises the COREX Vertical Mill; go out a plurality of air valve motors 2 at mill place; it is characterized in that: on air valve motor 2, be separately installed with machine operation sensor 3; each sensor 3 is connected with the delay protection controller respectively; described delay protection controller comprises the signal source detection module that is connected with each sensor 3; connection judgment module behind the signal source detection module; connect grinding machine master motor control module and timing unit behind the judge module respectively; timing unit includes comparison module; and be connected with the signal source detection module, grinding machine master motor control module is connected with the power control loop of grinding machine master motor 1.
The system controller 4 that described delay protection controller is the DCS scattered control system, described system controller also connect air valve policer operation station 5.
The system controller 4 of described DCS scattered control system is connected with the control loop of each air valve motor 2.
Beneficial effect
Air valve delay protection device of the present utility model is by reasonably managing the air valve of Vertical Mill and control; make Vertical Mill under the situation of the of short duration putty of air valve, still can continue to produce; and be connected with DCS control system in the factory; after the fast reaction cleaning; can make to produce and continue; and reduced the frequent unlatching of Vertical Mill, help prolonging the service life of Vertical Mill.

Fig. 1 is the utility model connection diagram.
Fig. 2 is the schematic block diagram of delay protection controller in the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of air valve delay protection device that is used for the COREX Vertical Mill; the grinding machine master motor 1 that comprises the COREX Vertical Mill; go out two air valve motors 2 at mill place; on two air valve motors 2, be separately installed with machine operation sensor 3; two sensors 3 are connected with the delay protection controller respectively; described delay protection controller comprises the signal source detection module that is connected with two sensors 3; connection judgment module behind the signal source detection module; connect grinding machine master motor control module and timing unit behind the judge module respectively; timing unit includes comparison module; and be connected with the signal source detection module, grinding machine master motor control module is connected with grinding machine master motor 1 electric power loop.
The system controller 4 that described delay protection controller is the DCS scattered control system, described system controller also connect air valve policer operation station 5.The system controller 4 of described DCS scattered control system is connected with the control loop of each air valve motor 2.
This system is mainly by air valve motor 2, grinding machine master motor 1 in the practice; DCS dcs controller 4 and active station 5 are formed; the whole protecting system utilizes the Automatic Control Theory of DCS Distributed Control System, according to two air valve tripping operations grinding machine master motor 1 trip condition is set action automatically by it.
After in two air valves a tripping operation being arranged, do not trip with interior grinding machine master motor 1 control at 5 minutes, if do not handle after 5 minutes, then the signal of passing back according to machine operation sensor 3 is controlled 1 tripping operation of grinding machine master motor.
And after two air valves trip simultaneously or in back 5 minutes of tripping operation another trip then control grinding machine master motor 1 directly tripping operation to prevent putty.
Compare with the existing system setting; the utility model has used the automatically operation principle of control of DCS Distributed Control System; situation in conjunction with the quick repairing time in the practice; set the time of delay tripping protection by active station; both guaranteed the continuously uninterrupted of production; can because of putty or frequently tripping operation cause and produce intermittently, avoided again the Frequent trip of grinding machine master motor 1 to cause that Vertical Mill is frequent to be opened and reduce service life, reduced machine cost.
