Abstract
Provided is a dry ash bulk machine control system using a PLC to control. The system is characterized in that on the basis of an original relay control circuit of a dry ash bulk machine, a manual control function is remained, and a programmable logic controller (PLC) is added to realize an automatic control function. The programmable controller is used to realize an automatic ash unloading function of the dry ash bulk machine, so as to improve stability of the control system, and reduce labor intensity of personnel.
Description
Technical field
The present invention relates to electricity generating equipment technical field, be specifically related to a kind of dry ash bulk machine control system adopting PLC to control.
Background technology
Dry ash bulk machine manually, automatically control all adopt pure relay circuit, the automatic control mode under relay circuit is immature, can only use at ordinary times and manually put ash, and personnel labor intensity is large, and accurately cannot control grey tank car material level and cause overload of vehicle.
Summary of the invention
Technical matters to be solved by this invention is that a kind of method is simple, the dry ash bulk machine control system that the employing PLC that practicality is good controls.
Technical matters to be solved by this invention realizes by the following technical solutions:
The dry ash bulk machine control system adopting PLC to control, is characterized in that, on the former relay control circuit basis of dry ash bulk machine, retains Non-follow control function, increases a Programmable Logic Controller (PLC) and realize automatic control function;
Control method is as follows:
Retain Non-follow control function, automatic control loop is all realized by PLC, the lifting of loading spout is manually, all can operate under automated manner, the decline interlocked startup that puts in place of loading spout takes out dirt blower fan, material level blower fan, sack cleaner, a newly-increased key unloads grey button, button is pressed rear time delay 60s and is opened discharging dome valve (guarantee taken out in tank body dirt blower fan take out put ash for negative pressure is beneficial to), the false alarm caused is changed for hiding pressure in dome valve unlatching moment stuff level switch, arrange the full signal lag 2s of material to report to the police, interlocking close discharging dome valve after the full signal alarm of material, time delay 30s automatic lifting loading spout, stop taking out dirt blower fan, material level blower fan, sack cleaner the alerting signal that resets, wait for next time and unload ash.For preventing discharging dome valve after the full warning of material because the faults such as valve bite can not be closed in time, warning, blocking function are set, when in 5s after the full signal of material triggers, dome valve shutdown signal does not arrive the locking loading spout also alarm operating personnel that automatically rise and takes urgent measure.
Dry ash bulk machine control loop is pure Control, and the application increases Programmable Logic Controller on original relay control circuit basis, adopts programming in logic to realize dry ash bulk machine automatic ash-discharging.The present invention adopts Programmable Logic Controller to realize dry ash bulk machine automatic ash-discharging function, improves stability of control system, alleviates personnel labor intensity.
The invention has the beneficial effects as follows:
1) achieve real dry ash bulk machine automatically to control.
2) labour intensity of operating personnel is alleviated.
3) manyly there is not overloading again in what by material level interlocking, standard ash tank car can be filled.
4) PLC control system controls more stable than relay circuit.
Accompanying drawing explanation
Fig. 1 is PLC elementary diagram of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of dry ash bulk machine control system adopting PLC to control, on the former relay control circuit basis of dry ash bulk machine, retains Non-follow control function, increases a Programmable Logic Controller (PLC) and realize automatic control function.PLC adopts the one-piece type Body Controller of Schneider Twido series TWDLCPA16DR, and 9 24V direct current inputs, 7 relays export, and meet on-the-spot needs completely, can also reserve enough inputs, output channel is for subsequent use.By procedure configuration, bulk machine automatic control mode is realized by PLC.Finally realize bulk machine automatic control function, comprise a key and put grey function, material level interlock, warning function etc.
Bulk machine control principle before transformation:
Grey tank car enter specify unload grey position time, loading spout manually falls and enters tank car feeding mouth by operating personnel, manually boot and take out dirt blower fan, material level blower fan, sack cleaner, manually opened discharging dome valve, whether fill according to comprehensive descision ash tank cars such as putting the ash time, manual-lock discharging dome valve, hand hoisting loading spout, to tip position, manually stops taking out dirt blower fan.
Bulk machine control principle after transformation:
Retain Non-follow control function, automatic control loop is all realized by PLC, the lifting of loading spout is manually, all can operate under automated manner, the decline interlocked startup that puts in place of loading spout takes out dirt blower fan, material level blower fan, sack cleaner, a newly-increased key unloads grey button, button is pressed rear time delay 60s and is opened discharging dome valve (guarantee taken out in tank body dirt blower fan take out put ash for negative pressure is beneficial to), the false alarm caused is changed for hiding pressure in dome valve unlatching moment stuff level switch, arrange the full signal lag 2s of material to report to the police, interlocking close discharging dome valve after the full signal alarm of material, time delay 30s automatic lifting loading spout, stop taking out dirt blower fan, material level blower fan, sack cleaner the alerting signal that resets, wait for next time and unload ash.For preventing discharging dome valve after the full warning of material because the faults such as valve bite can not be closed in time, warning, blocking function are set, when in 5s after the full signal of material triggers, dome valve shutdown signal does not arrive the locking loading spout also alarm operating personnel that automatically rise and takes urgent measure.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
