Operation, to guarantee the operational safety of system.In Fig. 1, still kettle safety interlocking control process is as follows:
1) when, 1# still kettle needs work, manually opened two sides kettle door sealing balloon valve 6, operator feeds intake, to
1# start button on point touching screen after feeding intake, touch screen issue PLC enabling signal in control cabinet, kettle door shutdown hydraulic cylinder
Movement, kettle door are begun to shut off, and kettle door is issued close to switch closes signal in place, and hydraulic cylinder stops, and kettle door does not issue pass close to switch
It when signal in place, i.e. PLC do not receive close to switching signal, is automatically stopped, triggering alarm module prompts warning message, operator
Equipment is maked an inspection tour, reason is searched.The movement of clip rotating hydraulic cylinder, the rotation of kettle badge hoop is issued close to switch closes signal in place, hydraulic
Cylinder stops, and the rotation of kettle badge hoop does not issue pass signal in place close to switch, is automatically stopped, and prompts warning message.Steam discharge solenoid valve 3
Begin to shut off to issue close in place signal, main steam discharge solenoid valve 7 begin to shut off to issue close signal, solenoid valve 3,7 are not sent out in place
Signal in place is closed out, is automatically stopped, and warning message is prompted.Sealing bypass solenoid valve 2, which is started to open to sending, reaches a signal, opens
Begin to be that both ends seal groove is inflated, seal groove inflation delay T11=15 second.It is started to open into vapour electric control valve 8, starts to rise in kettle
Pressure, until reaching operating pressure.After reaching operating pressure, self-sealing bypass solenoid valve 1 starts to open to sending and reaches a signal,
It seals steam pipe way solenoid valve 2 to close to pass signal in place is issued, realizes kettle self-sealing.Pressure, temperature signal in kettle is anti-at any time
It is fed to PLC, and then feeds back to touch screen.Operating pressure can be needed to be arranged on the touchscreen according to production technology, PLC can be according to setting
The operating pressure set carries out PID automatic adjustment into vapour electric control valve 8, rationally controls the air inflow in 1# still kettle, makes kettle
Interior steam pressure maintains the operating pressure of setting.
2), after the completion of 1# still kettle technique, if you do not need to 2# still kettle carries out leading vapour, operator's point touching screen
Upper 1# stop button.Electric control valve 8 is closed in place, and solenoid valve 7 is opened to sending and reaches a signal, and solenoid valve 3 is opened extremely
A signal is reached in sending, and 1# still kettle starts steam discharge, until exhaust pneumoelectric magnet valve is opened to hair after pressure is zero in 1# still kettle
It (can voluntarily be adjusted) after reaching signal T12=60 second out, complete exhaust vapour.1# still kettle self-sealing bypass solenoid valve 1 is closed extremely
Signal, steam discharge solenoid valve 3 close extremely sending pass signal, the closing of exhaust vapour solenoid valve 4 to sending pass in place in place in place for sending pass
Signal, main steam discharge solenoid valve 7, which are closed to sending, closes signal in place.Electric slurry valve 5 automatically opens to sending and reaches a signal, to
In kettle slurry mixture discharge after, setting T13=2min(can voluntarily adjust) afterwards electric slurry valve 5 be automatically closed to issue close arrive
Position signal.Clip rotating hydraulic cylinder starts to act, and the rotation of kettle badge hoop is issued close to switch reaches a signal, and hydraulic cylinder stops,
The rotation of kettle badge hoop does not issue close to switch reaches a signal, is automatically stopped, prompts warning message.Kettle door enabling hydraulic cylinder is dynamic
Make, kettle door starts to open, and kettle door issues close to switch and reaches a signal, and hydraulic cylinder stops, and kettle door is not issued close to switch and reached
Position signal, is automatically stopped, and prompts warning message.1# still kettle is automatically stopped step completion, and operator can be according to field condition
Feeding is carried out in into kettle.
3), after the completion of 1# still kettle technique, carry out leading vapour if necessary to 2# still kettle, on point touching screen 2# lead vapour by
Button, 2# still kettle start automatically.And then be automatically performed in succession 2# kettle door close in place, 2# kettle badge hoop rotate in place, row
Vapour solenoid valve 3 close in place, main steam discharge solenoid valve 7 close in place, sealing pipeline electromagnetic valve 2 opens in place.
It closes into vapour electric control valve 8 in place, then to pass is issued, signal, steam discharge solenoid valve 3 are beaten in place for the main closing of steam discharge solenoid valve 7
It opens to sending and reaches a signal, steam discharge solenoid valve 3 is opened to sending and reaches a signal, and steam starts to 2# steam pressure in 1# still kettle
Kettle leads vapour, until pressure is in a basic balance in 1#, 2# kettle.After two kettle pressure are in a basic balance, steam discharge solenoid valve 3, which is closed to sending, to be closed
Signal in place, 2# still kettle are started to open into vapour electric control valve 8, and PLC can be according to the operating pressure of setting into vapour electric adjustable
It saves valve 8 and carries out PID automatic adjustment, rationally control the air inflow in 2# still kettle, steam pressure in kettle is made to maintain the work of setting
Make pressure.When two kettle pressure are in a basic balance, after signal in place is closed in the sending of steam discharge solenoid valve 3, main steam discharge solenoid valve 7 is opened to sending
A signal is reached, 1# still kettle starts steam discharge, until exhaust pneumoelectric magnet valve opens T12=60 second after pressure is zero in 1# still kettle
(can voluntarily adjust) completes exhaust vapour.Then 1# still kettle starts automatic running to 1# stop mode, until 1# still kettle is automatic
Stop step completing, operator can enter according to field condition carries out feeding in kettle.
Relative to the process that still kettle before is controlled by relay and key, the utility model has the following advantages:
1, in the case where there is emergency episode, control cabinet can be grasped by button skilled hand and is operated manually；2, kettle door switch, kettle door
Clip rotary setting limit switch, if control cabinet PLC does not receive signal in place, system is automatically stopped, and triggering alarm module mentions
Show warning message, operator need to make an inspection tour field device, search reason, just can be carried out and be automatically brought into operation in next step；3,PLC
It acquires each solenoid valve and reaches position, the signal of pass in place, if PLC does not receive open and close signal in place, system is automatically stopped,
Warning message is prompted, operator need to make an inspection tour field device, search reason, just can be carried out and be automatically brought into operation in next step；4,
When there are more still kettle paired runnings, vapour operation button is led on point touching screen, can accomplish to be free from risk, fault-free, conveniently
It fast carries out leading vapour, rationally using remaining vapour in kettle, reduces production cost；5, the utility model can pass through setting superpressure, overtemperature etc.
Warning circuit generates alarm signal when there is accident；6, the utility model is electrically at low cost, and automation is at high cost, passes through a little
Virtual push button on touch screen is hit, realizes that still kettle start & shutdown through one key, a key lead vapour, foolproof full-automatic control system the degree of automation
Height, automatic control is at low cost, there is no required by having to operating staff technical ability, using effect is good.
The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art can also make a variety of changes accordingly
Change, but it is any with the utility model equally or similar variation should all cover it is within the protection scope of the present utility model.
