Abstract
The utility model discloses a cement filler silo dust removing and card swiping ash blowing automatic control system. The system mainly comprises master switches which take electricity in a card inserting manner, a controller, an execution mechanism and a host PC. The mater switches are respectively installed at the front end of a corresponding feeding electromagnetic turnover panel; each mater switch is connected with the power line; a first relay controls an intermediate relay in a far-end control box; the intermediate relay is a normally open coil and connected between a power supply and a signal input terminal of the controller; two output control intermediate relays are respectively connected at two corresponding output control terminals of the controller, and normally closed contacts of the two output control intermediate relays are in series connection with each other so as to achieve electric interlock; and the two output control intermediate relays control a control blower fan or a vibrator to operate. The technical problems that a traditional manual control system is complex in circuit, more cables are used, installation and debugging are relatively tedious, and inspection tour cannot be carried out for equipment regularly and the like can be solved.
Description
Technical field
The utility model 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 has generally adopted dedusting and the material-uploading style of the manual control combining with stirring system, the circuit more complicated of its control system, and it is more that cable is used, and Installation and Debugging are also more loaded down with trivial details.
Utility model content
The purpose of this utility model is to provide the dedusting of a kind of cement flour feed bin and blows grey automation control system with swiping the card, with solve that complex circuit, cable that traditional manual control system exists use more, Installation and Debugging are more loaded down with trivial details and can not be regularly equipment be patrolled and examined etc. to technical matters.
In order to realize above-mentioned utility model object, the technical scheme that the utility model adopts is as follows:
The dedusting of a kind of cement flour feed bin is blown 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 that limits feeding port, be mounted respectively at corresponding material loading electromagnetic turnover front end, described each control switch is connected with line of electric force by air switch with after corresponding the first relay and the series connection of electromagnetic turnover control coil, the coil series connection of the normally opened contact of described the first relay and auxiliary reclay corresponding in 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, between two output control terminals of correspondence of controller and power end, be connected to respectively two outputs and control auxiliary reclays, the normally closed contact of these two output control auxiliary reclays is realized electrical interlocks in the mode of mutually connecting, the normally opened contact that auxiliary reclay is controlled in described two outputs is 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..
The technical solution of the utility model tool has the following advantages: taking mixing plant dust pelletizing system as control object, adopt PLC and field control combined technology, design the applicable dedusting control system of a set of mixing plant, this system Installation and Debugging difficulty is little, can effectively avoid the generation of material loading mistake, reduce operating personnel's working strength; Appliance computer carries out on-line monitoring to dust pelletizing system, regularly equipment is patrolled and examined, and ensures that whole system is reliable, energy-saving safe.
Brief description of the drawings
Fig. 1 is the electric circuit constitute schematic diagram of the present utility model.
Embodiment
Concrete structure of the present utility model and principle of work are as follows: referring to Fig. 1, mainly comprise control switch, controller, topworks and the upper PC of plug-in card way to take power; Control switch is the working method of plug-in card power taking, claim again plug-and-consume switch, comprise magnetic card electricity-getting switch, IC-card electricity-getting switch etc., this switch is conventional in hotel guest room, in the time that guest enters guest room, CUSTOM HOUSE HOTEL is inserted specially in card electricity-getting switch, just can use the equipment such as illumination, air-conditioning and TV in guest room, after walking, extract CUSTOM HOUSE HOTEL and just can close (time delay) above-mentioned consumer.This control switch is mounted respectively at corresponding material loading electromagnetic turnover front end, described each control switch is connected with line of electric force by air switch with after corresponding the first relay and the series connection of electromagnetic turnover control coil, the coil series connection of the normally opened contact of described the first relay and auxiliary reclay corresponding in 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, between two output control terminals of correspondence of controller and power end, be connected to respectively two outputs and control auxiliary reclays, the normally closed contact of these two output control auxiliary reclays is realized electrical interlocks in the mode of mutually connecting, the normally opened contact that auxiliary reclay is controlled in described two outputs is 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 major control device (PLC) is realized soft start and the programmed control to cleaner.First utilize the plug-in card electricity getting device (control switch) being 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 advance inner software, controls topworks and carries out corresponding a series of actions according to program, reaches 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 operational scheme:
1. system powers on, QF1 ~ QF9 air switch energising, PLC power-on self-test, the system internal processes that brings into operation.
2. driver's plug-in card, this example of electricity getting device SB1(is taking SB1 plug-in card as example) electric, relay K M4 energising, electromagnetic turnover control coil YM4 energising is simultaneously opened, the trap of often bursting at the seams of KM4 is closed, and causes the auxiliary reclay KA4 energising in far-end control box.The trap of often bursting at the seams of KA4 is closed, produce a lasting electric signal at the I1 of PLC input end, trigger PLC internal processes according to the instruction of writing in advance, replace output signal from Q1, Q2 output terminal, 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..
For prevent KA1, KA2 simultaneously electric, mutually connect at the normally closed contact of KA1, KA2, carry out electrical interlocks.
4. in the time that fly-ash separator discharging is not smooth, press SB4 button, auxiliary reclay KA3 energising, KM3 obtains electric, and motor obtains electric, and discharging vibrator works is accelerated discharge rate.
