Description
Technical field
The present invention relates to a kind of dedusting of concrete mixing plant and the control device of material loading.
Background technology
Most of concrete mixing plant of Present Domestic generally have employed dedusting and the material-uploading style of the Non-follow control combined with stirring system, the circuit more complicated of its control system, cable more, and Installation and Debugging are also more loaded down with trivial details.
Summary of the invention
The object of this invention is to provide a kind of cement filler silo dedusting with swiping the card blows grey automation control system, with solve complex circuit that traditional manual control system exists, cable more, Installation and Debugging are more loaded down with trivial details and can not regularly carry out the technical matters such as patrolling and examining to equipment.
In order to realize foregoing invention object, the technical solution adopted in the present invention is as follows:
A kind of cement filler silo dedusting blows grey automation control system with swiping the card, and this system mainly comprises by the control switch of plug-in card way to take power, controller, topworks and upper PC, described controller is connected with upper PC, described control switch is the opened and closed positions limiting feeding port, be separately mounted on corresponding material loading electromagnetic turnover front end, described each control switch is connected with line of electric force by air switch after connecting with the first corresponding relay and electromagnetic turnover control coil, the coils connected in series of the auxiliary reclay that the normally opened contact of described first relay is corresponding with control box, be connected on the DC terminal of direct supply, the normally opened contact of described auxiliary reclay, be connected between power supply and controller signals input end, be connected to two between output control terminal and power end respectively in the correspondence two of controller and export control auxiliary reclay, these two export the normally closed contact controlling auxiliary reclay and realize electrical interlocks in the mode of mutually connecting, described two normally opened contacts exporting control auxiliary reclay are connected in same electric loop with corresponding action control relay coil, and the normally opened contact of described action control relay is serially connected in the power supply loop of controlled control blower fan or Vib..
Technical scheme tool of the present invention has the following advantages: with mixing plant dust pelletizing system for control object, adopt PLC and field control combined technology, design the dedusting control system that a set of mixing plant is suitable for, this system Installation and Debugging difficulty is little, effectively can avoid the generation of material loading mistake, reduce the working strength of operating personnel; Appliance computer carries out on-line monitoring to dust pelletizing system, regularly patrols and examines equipment, ensures that whole system is reliable, energy-saving safe.
Accompanying drawing explanation
Fig. 1 is circuit theory of constitution figure of the present invention.
Embodiment
Concrete structure of the present invention and principle of work as follows: see Fig. 1, mainly comprise the control switch of plug-in card way to take power, controller, topworks and upper PC; Control switch is the working method of plug-in card power taking, also known as plug-and-consume switch, comprise magnetic card electricity-getting switch, IC-card electricity-getting switch etc., this switch is conventional in hotel guest room, when guest enters guest room, CUSTOM HOUSE HOTEL is inserted in special card electricity-getting switch, just can use the equipment such as the illumination in guest room, air-conditioning and TV, extract CUSTOM HOUSE HOTEL after walking and just can close (time delay) above-mentioned consumer.This control switch is separately mounted on corresponding material loading electromagnetic turnover front end, described each control switch is connected with line of electric force by air switch after connecting with the first corresponding relay and electromagnetic turnover control coil, the coils connected in series of the auxiliary reclay that the normally opened contact of described first relay is corresponding with control box, be connected on the DC terminal of direct supply, the normally opened contact of described auxiliary reclay, be connected between power supply and controller signals input end, be connected to two between output control terminal and power end respectively in the correspondence two of controller and export control auxiliary reclay, these two export the normally closed contact controlling auxiliary reclay and realize electrical interlocks in the mode of mutually connecting, described two normally opened contacts exporting control auxiliary reclay are connected in same electric loop with corresponding action control relay coil, and the normally opened contact of described action control relay is serially connected in the power supply loop of controlled control blower fan or Vib..
Control system primary control (PLC) realization is to the soft start of cleaner and programmed control.First utilize the plug-in card electricity getting device (control switch) be arranged on material loading electromagnetic turnover to limit the opened and closed positions of feeding port, which number turnover panel which number card opens, and prevents wrong material on powder tank car.Then controller sends instruction by being stored in inner software in advance, controls topworks and carries out corresponding a series of actions according to program, reach the object of dedusting.
PLC is connected with host computer (PC) by software, can on-line monitoring system ruuning situation, and can need to modify to the program of PLC inside according to the difference of producing.
System cloud gray model flow process:
1. system electrification, QF1 ~ QF9 air switch is energized, PLC power-on self-test, and system brings into operation internal processes.
2. driver's plug-in card, this example of electricity getting device SB1(is for SB1 plug-in card) electric, relay K M4 is energized, and electromagnetic turnover control coil YM4 energising is simultaneously opened, and the trap of often bursting at the seams of KM4 is closed, and causes the auxiliary reclay KA4 in far-end control box to be energized.The trap of often bursting at the seams of KA4 is closed, then produce a lasting electric signal at the I1 input end of PLC, trigger PLC internal processes according to the instruction of writing in advance, from Q1, Q2 output terminal alternating output signal, by the break-make of auxiliary reclay KA1, KA2 pilot relay KM1, KM2.Control motor by KM1, KM2, and then control the work of blower fan and Vib..
3. in order to prevent KA1, KA2 simultaneously electric, mutually connect at the normally closed contact of KA1, KA2, carry out electrical interlocks.
4., when fly-ash separator discharging is not smooth, press SB4 button, auxiliary reclay KA3 is energized, and KM3 obtains electric, and motor obtains electric, discharging vibrator works, accelerates discharge rate.
5. host computer (PC) is connected with PLC by software, can on-line monitoring system ruuning situation, and according to the different needs produced, can be modified to the program of PLC inside by control cables WS.
If 6. have two or more electricity getting devices simultaneously electric, system carries out work according to program equally.
