Abstract
The invention discloses a method and a system for controlling a feeder and a feeding belt in a grinding station. The method specifically comprises the following steps: the current value of a main circuit of a grinder is monitored in real time during operation of the grinder; the current value is compared with the standard current value for working of the grinder; when the current value of the main circuit is smaller than the standard current value, a feeder and a feeding belt run continuously; and when the main circuit is greater than or equal to the standard current value, the feeder and the feeding belt stop running under control. According to the invention, start-stop of the feeder and the feeding belt is controlled by the working current of the grinder instead of being controlled separately, so that the feed quantity of the grinder is ensured, full grinding is avoided, the grinder can conduct production continuously, the motor is protected from overload, the needs of production are satisfied, smooth and uninterrupted production is ensured, the motor is effectively protected from overload burnout due to full grinding and a large amount of materials, and the cost of electricity is reduced.
Description
Technical field
The present invention relates to construction material production technical field, be specifically related to technology of producing cement neck
Territory, being specifically related to batcher and the control method of charging belt and control in a kind of grinding station is
System.
Background technology
At present, rotary kiln is typically used to produce in field of cement production, the work of rotary kiln
Needing to coordinate grinding station to carry out, there is bigger problem after installing in the new grinding machine in grinding station, uses
Longer in the charging belt length of raw coal feeding, and do not take into account after the installation of grinding station
The impact of the length of material belt, after grinding machine electric current reaches predetermined value, grinding machine carries out coal-grinding work,
Now need to stop feeding, but owing to charging belt is individually to control, start at grinding machine
But can not stop feeding during work at once, and grinding machine and batcher all can be automatically stopped, feeding skin
Band continues feeding in grinding machine, and feeding too much causes the milling capacity of abrasive body not adapt to；When
Raw meal particle size becomes big, when grindability is deteriorated, reduces feeding the most in time；Material moisture is too high,
Improper ventilations etc. cause material sticks in steel ball and backing surface, block storehouse plate and the seam of grate plate
Gap, discharge difficulty, the most unnecessary material causes the vexed mill of grinding machine, and vexed mill not only can not normally produce
Fine coal, and energy consumption is the highest, is additionally easily caused grinding machine impaired, causes grinding machine fault, follow-up
Maintenance, replacement cost the highest.
Summary of the invention
It is desirable to provide in a kind of grinding station batcher and the control method of charging belt and
Control system, to solve can not regrind when machine works due to charging belt in existing grinding station to stop
Feeding and be easily caused the damp production existing for the vexed mill of grinding machine, energy consumption is high, grinding machine is easily damaged,
Follow-up maintenance high in cost of production problem.
The present invention is achieved by following technical solution:
Batcher and the control method of charging belt in a kind of grinding station, the method is particularly as follows: grind
The current value of grinding machine main circuit monitored in real time by machine when running, and by this current value and grinding machine work
Standard current value contrasts, the batcher and upper when the current value ＜ standard current value of main circuit
Material belt continuous running, controls batcher and upper when the current value >=standard current value of main circuit
Material belt shuts down.
Realize the control system bag of the control method of batcher and charging belt in above-mentioned grinding station
Include the ammeter on the main circuit being arranged on grinding machine, ammeter is provided with data acquisition unit, number
Being connected according to harvester and a microprocessor, microprocessor and a controller are connected, controller end
It is connected with feed motor and feeding motor.
Described feed motor is the driver element of batcher.
Described feeding motor is the driver element of charging belt.
The invention has the beneficial effects as follows:
Compared with prior art, batcher and the control of charging belt in the grinding station that the present invention provides
Method processed and control system, individually controlled change by the start-stop of batcher and charging belt by original
For being controlled by the operating current of grinding machine, this ensures that thering mill feeding amount, grinding machine will not be sent out
Raw vexed mill phenomenon, makes grinding machine to produce continuously, and also protecting motor will not transship simultaneously, full
The needs that foot produces, it is ensured that produce uninterrupted trouble-free operation, motor can be effectively protected because of vexed
Abrasive material is many and transships and burns out, and also reduces grid electricity fee cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of control system in the present invention；
In figure: 1-grinding machine, 2-main circuit, 3-ammeter, 4-data acquisition unit, 5-microprocessor,
6-controller, 7-feed motor, 8-feeding motor.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described further, but required guarantor
The scope of protecting is not limited to described；
As it is shown in figure 1, the present invention provide grinding station in batcher and the control system of charging belt
System, it includes the ammeter 3 being arranged on the main circuit 2 of grinding machine 1, ammeter 3 is provided with number
According to harvester 4, data acquisition unit 4 is connected with a microprocessor 5, microprocessor 5 and a controller
6 are connected, and controller 6 end is connected with feed motor 7 and feeding motor 8, and feed motor 7 is for giving
The driver element of material machine, feeding motor 8 is the driver element of charging belt.During use, main electricity
Road 2 energising makes grinding machine 1 work, and now ammeter 3 monitors the current value of main circuit 2, data in real time
Numerical value in harvester 4 collected current table 3 by this numerical value input microprocessor 5, micro-process
The data collected are contrasted by device 5 with normal data, when the real-time current value collected is low
When standard current value, controller 6 does not works, and now batcher and charging belt work on
And grinding machine 1 is carried out lasting feeding；When the current value collected is more than or equal to standard current value
Time, microprocessor 5 sends signal and controls feed motor 7 and feeding motor 8 by controller 6
Brake, it is achieved that when grinding machine 1 reaches standard working current value, be automatically switched off stopping feeding simultaneously,
The i.e. start-stop of batcher and charging belt is controlled by the electric current of grinding machine 1 completely, thus ensures
The inlet amount of grinding machine 1, grinding machine 1 will not occur vexed mill phenomenon, make grinding machine 1 to produce continuously,
Also protect motor will not transship simultaneously, meet the needs of production.Within one day, produce by grinding station
Within 8 hours, calculate, the production time can be saved 2 hours, grinding station general power 272KW, electricity can be saved
Take 272 × 2 × 0.47=255.8 unit.
