Description
Technical field
The utility model belongs to coking of coal dry coke quenching production technical field more particularly to a kind of rotary sealing valve in coke dry quenching people
Port lid.
Background technology
Rotary seal valve is the component part of discharging device for coke in the cold burnt discharge system of dry coke quenching, and effect is vibrating feed
The coke that device is quantitatively discharged continuously is discharged under air-tight state.
Rotary sealing valve in coke dry quenching operating temperature requirements are no more than 210 DEG C, using N2Sealing, it is close in processing dry coke quenching rotation
It, just must be into being about to rotate if rotary seal valve is taken to rotate forward, in the case that reversion cannot all discharge foreign matter when sealing valve failure
Sealing valve manhole cover is opened, into rotary seal valve inside by foreign body.In practical maintenance process, it is found that existing rotation is close
Envelope valve manhole cover has the following disadvantages：
1) since the requirement of rotary seal valve manhole cover must be tight, when rotary seal valve seals, prior art needs are adopted
It will be filled between gasket and valve body, manhole cover with high-temperature seal adhesive, though such sealing means disclosure satisfy that production needs,
Result in opening the time of rotary seal valve manhole cover 2 hour operations of needs under malfunction；
2) it when processing rotary seal valve failure need to open manhole cover, as long as manhole cover is slightly loosened, must just reduce
Otherwise the living load of dry coke quenching can spray a large amount of high temperature toxic gases at rotary seal valve manhole, can cause production operation
Personnel are poisoned and burn and scald；
3) after reducing living load, being forced to stop production for dry coke quenching has been resulted in, the stable operation of dry coke quenching has been influenced, causes
Dry quenched coke carbon yield reduces, and influences dry coke quenching steam raising amount；If overlong time, dry quenching laying furnace body can also be made
Into injury；
In conclusion it is badly in need of for existing rotary seal valve manhole cover is insufficient present in maintenance process to existing manhole
Lid is improved, and makes it that can handle rotary seal valve failure safely, rapidly under poor working conditions.
In the prior art, it is quick to disclose a kind of rotary sealing valve in coke dry quenching manhole by patent publication No. CN203419489U
Headstock gear is mainly compressed rotary seal valve with the elastic deformation of spring, and over time, this position is in life
It is ceaselessly to shake between term, while is high temperature position again, it is easy to causes spring breaking down, cause large area leakage gas, give
Production brings baneful influence.
Invention content
In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a kind of rotary sealing valve in coke dry quenching manhole
Lid, in rotary seal valve blocking foreign matter or ironware, post operation personnel can in time open manhole cover, avoid the occurrence of personnel
Poisoning reduces the time that influence dry coke quenching normally produces.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of rotary sealing valve in coke dry quenching manhole cover, including expanding tense machine, cover, pedestal, flange, support plate, in support plate
Equipped with pedestal, groove, the groove grafting of cover and pedestal, support plate bottom and flange welding, flange and rotation are equipped in pedestal
Sealing valve housing is fixedly connected；Expanding tense machine top is connected with bolt, and bolt bottom end is resisted against in cover, and expanding tense machine will by bolt
Manhole cover is compressed with pedestal and is sealed；Pedestal is bolted to connection with rotatory sealing valve housing.
The expanding tense machine bottom is equipped with handgrip.
The cover is fixed with handle.
Reserved thermometer hole is equipped among the cover.
Refractory seals glue and gasket are equipped between the pedestal and rotatory sealing valve housing.
Rubber sheet gasket is equipped in the groove.
Compared with prior art, the beneficial effects of the utility model are：
Rotary sealing valve in coke dry quenching manhole cover structure is simple, can make, with rotary seal valve manhole size to matching；
Post personnel are relatively laborsaving during manhole cover is opened, and shorten the processing time of failure.Using refractory seals glue, pad
Piece, rubber sheet gasket can ensure that sealing effect.Cover and pedestal use expanding tense machine fixing seal using inserting mode, handling and
In recovery process, the equal used time is shorter, can ensure the personal safety of operating post personnel, while improves the production effect of dry coke quenching
Rate.
