principle of work:
1. original state:
A. launching spring (4) locates to stretch state and makes to launch bar (11) and locate right position, simultaneously, a left side stir magnetic valve (33), the right side stir magnetic valve (34), when triggering cylinder solenoid valve (35) and connecting source of the gas, make to trigger that cylinder (15), a left side are stirred cylinder (17), the right side is stirred cylinder (23) and located retracted state, locking stop (14) is separated with transmitting tailgate (12), gear (6) and craspedodrome tooth (27) engagement, motor start switch (16) be closed, stir starting switch (25) closed, lock starting switch (13) and often open.
B. automatically emission temperature value is set, and during due to converter tapping, initial stage fire box temperature is higher, approach and can decrease latter stage, and every furnace temperature is poor substantially fixing, usings this constant as temperature switch signal feeding value, by temperature acquisition switch (31), is transferred to PLC.
C. programming and by installation to PLC:
Network 1: after bus, parallel connection started after the normal battle of normal battle, rly., then series connection stops normally closed point and relay1 coil;
Network 2: after bus tandem promoter often make war, the normally closed point of timing register 1, relay1 coil;
Network 3, after bus in parallel start often make war, after normal battle of rly., two normally closed switch of connecting, more simultaneously connect relay1 coil and timing register 1(establishes: 1 second) and timing register 2(establish: 2 seconds);
Network 4: after bus in parallel start often make war, intermediate relay often makes war, then after the normally closed point of the timing register 4 of connecting, connect intermediate relay coil simultaneously, timing register 3(establishes: 15 seconds), timing register 4(establishes: 15 seconds);
Network 5: after bus after the normal battle of timing register 2 in parallel, relay normally open, the normally closed point of series connection timing register 3, relay1 coil.
2. system accumulation of energy and dress ball
Press system power-on switch (29) by PLC program network 1 make intermediate relay coil (38) that system is obtained is electric in electric connection intermediate relay contact (39).Now, can by PLC program network 2, make motor relay coil (36) obtain electric motor relay contact (37) closure that allows because of the closure of motor start switch (16) allows motor (19) inverse time rotate, by connecting hand (20), step-down gear (18), fifth wheel (21), transmission shaft (7), positioning key (8) driven gear (6) rotation, gear (6) promotes craspedodrome tooth (27), transmitting bar (11) left-hand moves, and emitting head plate (3) compression ejection-spring (4) starts accumulation of energy.When touching, transmitting tailgate (12) makes to lock starting switch (13) when closed, by PLC program network 3, making to trigger cylinder solenoid valve (35) obtains electric and drives lock cylinder (15) to promote locking stop (14) pinning transmitting tailgate (12) Return-ing direction, timing is in the time of 1 second, in PLC program network 2, the normally closed of timing register opened, make motor relay (27) dead electricity, motor (19) stops operating; In the time of 2 seconds, in PLC program network 5 the normal switching of timing register close make a left side stir magnetic valve (33), the right side stir magnetic valve (34) electric, make a left side stir cylinder (17), the right side and stir that cylinder (23) promotes left Shifting rack (10), left Shifting rack (5) is released gear (6) to finish with the separated accumulation of energy of craspedodrome tooth (27).Because the left-hand of emitting head plate (3) moves, transfer lime (24) endoporus is opened, slag-blocking ball (28) is rolled in transmitting tube (2).
3, slag-blocking ball transmitting
(1) automatic emission process:
In the converter tapping later stage, temperature acquisition switch (31) Information Monitoring make to trigger magnetic valve (35) dead electricity by PLC program networking 3 when fire box temperature reaches set(ting)value, triggering cylinder (15) retracts locking stop (14) with to launch tailgate (12) release separated, energy release due to ejection-spring (4), promotes fast emitting head plate (3) slag-blocking ball (28) is launched to converter.
(2) artificial emission process:
At converter tapping later stage arbitrary period, press manual emission switch (32) and make to trigger magnetic valve (35) dead electricity by PLC program network 3, triggering cylinder (15) retracts locking stop (14) with to launch tailgate (12) release separated, energy release due to ejection-spring (4), promotes fast emitting head plate (3) slag-blocking ball (28) is launched to converter.
4, automated cycle process:
In each emission process, because all will touching, transmitting tailgate (12) stirs starting switch (25), when closed in the moment of stirring starting switch (25), in PLC program network 4, timing register 3 can disconnect PLC program network 5 after 15 seconds, make a left side stir magnetic valve (33), magnetic valve (34) dead electricity is stirred on the right side, allow a left side stir cylinder (17), the right side is stirred cylinder (23) and is driven, left Shifting rack (10), right Shifting rack (5) retracts gear (6) with the tooth of keeping straight on (27) and meshes, touch the closure of motor start switch (16) simultaneously, starter motor (19) running again, transfer lime (24) endoporus is opened, slag-blocking ball (28) is rolled into the intelligent automated cycle process in transmitting tube (2).
