When the 2 normal operations of fixed bed intermittent type vapourizing furnace, the sealed valve 7 of clack box 6 inside is opened, and this vapourizing furnace in-furnace dust slag enters dreg discharge box 26 by the vapourizing furnace bottom of furnace body; When grey under the needs, by industry controlling machine 1 under the PC bus is controlled to realize closing sealed valve 7, put in place by checking near switch 4 whether sealed valve 7 closes, open ash outlet 9 and can realize fixed bed intermittent type vapourizing furnace 2 normal operations ash at present, after following ash finishes, close ash outlet 9, ash outlet close qualified after, opening encapsulation valve 7 gets final product.
Before the chain Controlling System of oil circuit is for ash under the not blowing out during initial state, the ash outlet solenoid operated directional valve 21 that ash outlet oil cylinder 18 connects is not charged, ash outlet oil cylinder 18 oil-in band oil pressure, ash outlet oil cylinder 18 oil outlets are not with oil pressure, stretch out oil compression rod owing to ash outlet oil cylinder 18 rodless cavity cross-sectional areas receive pressure this moment, and ash outlet 9 is closed; The sealed valve solenoid operated directional valve 22 that links to each other with sealed valve oil cylinder 3 simultaneously is electriferous state not, so the time sealed valve oil cylinder 3 oil-in band oil pressure, oil outlet is in band oil pressure state all the time, sealed valve oil cylinder 3 rodless cavity cross-sectional area stressed areas cause cylinder rod to stretch out greater than rod chamber cross-sectional area stressed area, sealed valve 7 unlatchings this moment, this vapourizing furnace in-furnace dust slag enters dreg discharge box 26 by the vapourizing furnace bottom of furnace body.
After grey program begins under the not blowing out:
The first step: sealed valve 7 is closed: the sealed valve solenoid operated directional valve 22 that be connected with sealed valve 7 this moment is charged, sealed valve oil cylinder 3 oil-ins are in passive state after the sealed electromagnetic reversing valve is charged, rodless cavity does not have oil pressure to sealed valve oil cylinder 3 because rod chamber has oil pressure, rod chamber is stressed to cause the cylinder rod indentation, and this moment, sealed valve 7 was closed.
Second step: open ash outlet 9 on the basis that assurance sealed valve 7 is closed, the closed state of the sealed valve 7 continuity the first steps; The hydraulic control one-way valve 23 pressure-bearing oil-in places that link to each other with ash outlet oil cylinder 18 oil-ins receive pressure, but ash outlet hydraulic control one-way valve 23 interior hydraulic efficiency oil two-way flows this moment, ash outlet oil cylinder 18 continuous ash outlet solenoid operated directional valves 21 are charged, ash outlet oil cylinder 18 oil-ins do not have oil pressure, oil outlet band oil pressure, the 18 cylinder rod indentations of ash outlet oil cylinder, this moment, ash outlet 9 was opened.
The 3rd step: after following ash finishes, make 21 outages of ash outlet solenoid operated directional valve, this moment, ash outlet 9 was closed.
The 4th step: make 22 outages of sealed valve solenoid operated directional valve, this moment, sealed valve was opened; Be back to initial state.
The chain Controlling System of oil circuit in the utility model has chain function, in chain Controlling System, be provided with ash outlet hydraulic control one-way valve 23, liquid can realize uniflux at any time but under the stressed situation in its pressure-bearing oil-in place, liquid can oppositely flow by this valve.For this reason, if sealed valve solenoid operated directional valve 22 is not charged, namely sealed valve 7 is not closed, even then operator's mishandle, make ash outlet solenoid operated directional valve 21 charged, ash outlet oil cylinder 18 also will namely can't be opened ash outlet 9 because oil cylinder oil-in loop is cut off and can't moves.So just assurance only on the basis that sealed valve 7 is closed, could be opened ash outlet 9 this safety interlocking function.Equally, be in open period at ash outlet 9, because ash outlet solenoid operated directional valve 21 is charged, ash outlet oil cylinder 18 oil-ins do not have oil pressure, 24 of sealed valve hydraulic control one-way valves will can only not make hydraulic efficiency oil by uniflux because the pressure-bearing oil-in does not have pressure, even this moment people's mishandle is arranged, make 22 outages of sealed valve solenoid operated directional valve, sealed valve oil cylinder 3 oil-ins also will can't be with pressure because of being cut off, and so sealed valve 7 valve rods just can not stretch out and sealed valve 7 is opened.
