Description
Technical field
The present invention relates to a kind of coke dry quenching furnace, specifically a kind of dry coke quenching furnace roof bleeding device.
Background technology
Dry Quenching Technology is widely used in coking industry at present, and in dry coke quenching technique, furnace roof exhaust stack is direct
Connection dry coke quenching prestores room, for diffusing the indoor high-temperature gas that prestores, 900 DEG C or so of gas temperature.Exhaust stack top sets water seal
And manhole cover, by cylinder control manhole cover switch.Current design is substantially the parallel exhaust stack of being close to of cylinder and arranges, makes
With during, as exhaust stack diffuses high-temperature gas, the expansion after the cylinder block and piston of close exhaust stack side are heated becomes
Shape amount is more than opposite side, in the state of being in discontinuity all the time at the cooperation of cylinder body and piston during cylinder use, because
This causes cylinder to leak air in use for some time, clamping stagnation situations such as, service life is shorter, and breakdown maintenance rate is high, seriously
Have impact on the production efficiency of dry coke quenching technique.
Content of the invention
It is an object of the invention to provide a kind of dry coke quenching furnace roof bleeding device, it is able to ensure that the cylinder body of cylinder is equal with piston
Even be heated, make cylinder body and piston mating surface border uniform force, effectively extend the service life of cylinder, reduce equipment failure rate,
Improve the production efficiency of dry coke quenching technique.
The present invention for achieving the above object, is achieved through the following technical solutions：Including exhaust stack, at exhaust stack top export
Water seal is set, and water seal top arranges manhole cover, and manhole cover side is hinged with first connecting lever one end, by being hinged in the middle part of the first connecting lever
Seat is connected with exhaust stack, and the first connecting lever other end is connected with the piston rod of cylinder by driving member, and cylinder is hinged with mounting seat, gas
Cylinder is arranged along the extended line direction for diffusing pipe diameter.The driving member includes that connecting rod, connecting rod one end are hinged with the first connecting lever, connecting rod
The other end be hinged with one end of the second connecting lever, be hinged with mounting seat in the middle part of the second connecting lever, the second connecting lever other end and cylinder
Piston rod be hinged.Connecting rod is opened up near one end of the first connecting lever and install in bar hole, bar hole sliding axle, sliding axle and first
Connecting lever connects.
It is an advantage of the current invention that：The cylinder body and piston thermally equivalent of cylinder is able to ensure that, cylinder body and piston mating surface is made
Border uniform force, effectively extends the service life of cylinder, reduces equipment failure rate, improves the production efficiency of dry coke quenching technique
Deng.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
A kind of dry coke quenching furnace roof bleeding device of the present invention includes exhaust stack 1, arranges water at 1 top export of exhaust stack
Envelope 2,2 top of water seal arrange manhole cover 3, and 3 side of manhole cover is hinged with 4 one end of the first connecting lever, by being hinged in the middle part of the first connecting lever 4
Seat 5 is connected with exhaust stack 1, and 4 other end of the first connecting lever is connected with the piston rod of cylinder 9 by driving member, cylinder 9 and mounting seat 8
It is hinged, cylinder 9 is arranged along the extended line direction of 1 diameter of exhaust stack.During use, the stretching motion of 9 piston rod of cylinder is by transmission
Part is transferred to the first connecting lever 4, drives the first connecting lever 4 to rotate, so as to realize the open and close of manhole cover 3.Current this area skill
Art personnel have been generally acknowledged that drive dry coke quenching exhaust stack manhole cover cylinder trouble rate higher be that cylinder itself cannot be in hot environment
Medium-term and long-term use and caused, must often change the drive cylinder of manhole cover during dry coke quenching process operation.And the present invention is by gas
Cylinder 9 is arranged along the extended line direction of 1 diameter of exhaust stack, it can be ensured that it is poor that the diametric(al) of cylinder 9 will not produce heat, it is ensured that cylinder
Cylinder body and piston in the range of the heat radiation of exhaust stack 1 thermally equivalent, this improvement effectively extends the use longevity of cylinder
Life, enables cylinder be used in hot environment for a long time, reduces equipment failure rate, improves the production effect of dry coke quenching technique
Rate.
Driving member of the present invention can adopt various structures, and wherein preferred structure is：The driving member includes connecting rod 6,
6 one end of connecting rod is hinged with the first connecting lever 4, the other end of connecting rod 6 be hinged with one end of the second connecting lever 7, in the middle part of the second connecting lever 7 with
Mounting seat 8 is hinged, and 7 other end of the second connecting lever is hinged with the piston rod of cylinder 9.The structure have take up room little, be easy to putting
Dissipate pipe nearby to install, assembly precision demand is relatively low, do not receive Effect of Hyperthermic Environment a little.Certainly driving member of the present invention may be used also
Using other multiple drive mechanisms such as gear, sprocket wheel, but these structures take up room relatively large, and need to assembly precision
Ask higher, easily break down after temperature distortion in hot environment.
The present invention can open up bar hole in connecting rod 6 near one end of the first connecting lever 4 to prevent driving member from clamping stagnation occur
10, sliding axle 11 is installed in bar hole 10, sliding axle 11 is connected with the first connecting lever 4.
