In one particular embodiment of the present invention, the main cylinder 1 is connected with the flange round tube 9 being positioned above,
The flange round tube 9 is connected with condenser.
In order to facilitate above-mentioned technical proposal of the invention is understood, below by way of specifically used mode to above-mentioned skill of the invention
Art scheme is described in detail.
The conventional technical means such as welding can be used, is bolted in the mode of the present invention that is fixedly connected.
As shown in Fig. 2, the inside of main cylinder 1 is equipped with feeding screw 2, the right side of the main cylinder 1 is sealed, on right end
Portion is splitted as air inlet cinder notch 10, and the left end of main cylinder 1 is a driving motor（Air motor or hydraulic motor can also be used
Deng）7, the direction rotation of feeding screw 2 as needed can be driven, setting has the lime-ash out of taper below the barrel of main cylinder 1
Mouth 3, the diameter on 3 top of ash discharge cinder notch are less than the diameter of 3 lower part of ash discharge cinder notch, and ash discharge cinder notch 3 and curved surface sealing cover 4 cooperate,
It is opened and closed under the action of driving mechanism 6, there is ash slag bucket 5 below ash discharge cinder notch 3, for lime-ash access conduit is unified clear
Reason.Coupled logical flange round tube 9 is arranged at the top of main cylinder 1, for cracking gas to be accessed condenser.Opposite ash discharge cinder notch 3
Center barrel on be provided with lockable mechanism 8, can lock and locking curved surface sealing cover 4, guarantee close under the action of external impetus
It seals, does not leak cracking gas and lime-ash in operation.
It is protruded into pyrolysis furnace at the right end of cylinder 1 to flange round tube 9, lime-ash and cracking gas can be entered by air inlet cinder notch 10
In main cylinder 1.
The radial rotary face of flight and 1 inner wall of cylinder keep tangent cooperation in the rotary shaft of feeding screw 2, axial to turn
Lime-ash can be thoroughly shaved when dynamic and pushes to the discharge of ash discharge cinder notch 3.
As shown in figure 3, lockable mechanism 8 is a set of push-pull effort transformation mechanism being arranged on main cylinder 1, for realizing curved surface
Latch functions after the closure substantially of sealing cover 4 are suitble to the fast of curved surface sealing cover 4 due to the resistance brachium of lever in driving mechanism 6
Fast opening and closing movement, but it is difficult to ensure the lasting sealing for keeping curved surface sealing cover 4, the coupling mechanism force of lockable mechanism 8 is big, works as power device
（Electric cylinder, cylinder, oil cylinder etc.）When moving downward, the holding section of two levers is close to each other in lockable mechanism 8, and then clamps curved surface
Capping 4, is tamping it, power device, which moves to, just generates self-locking function when most descending, thus it is ensured that it seals and prevents to loosen, it is reversed to transport
When dynamic, locking is released, curved surface capping 4 can free-open-close.
As shown in figure 4, the inner curve of curved surface capping 4 is cylindrical surface, it is almost the same with the inner wall curved surface of main cylinder 1
A tubular structure is collectively formed with main cylinder 1 after 4 closure of curved surface capping；Curved surface capping 4 and ash discharge cinder notch 3 cooperate, curved surface
The sealing surface band of capping 4 and 3 touching position of ash discharge cinder notch is tapered, is conducive to mutually coincide, guarantees sealing.
Driving mechanism 6 and lockable mechanism 8 can connect controller, to realize the automation of ash discharge slag operation.
When specifically used, when temperature reaches 180 DEG C or so, lime-ash work, lime-ash and cracking in pyrolysis furnace are carried out out
Gas is entered in main cylinder 1 by air inlet cinder notch 10, and feeding screw 2 drives lime-ash and cracking gas to be moved to the left, and cracking gas passes through
Flange round tube 9 enters condenser, and lime-ash is gradually moved at ash discharge cinder notch 3 and constantly gathers here（Settable corresponding gear
Plate prevents the lime-ash from continuing to be moved to the left）；After a period of time, lockable mechanism 8 is acted, and releases the lockup state of curved surface capping 4,
Driving mechanism 6 acts, and curved surface capping 4 is opened, and lime-ash falls from ash discharge cinder notch 3, falls into ash slag bucket 5, to realize out
Lime-ash function.
In conclusion changing the skill that original pyrolysis furnace goes out lime-ash device by means of above-mentioned technical proposal of the invention
Art defect changes and cools and manually-operated problems for a long time, especially in high-volume（8 or more）Pyrolysis furnace is simultaneously
Production occasion, can be substantially energy saving, it can be achieved that be automatically brought into operation, and improves efficiency, saves a large amount of manpower and material resources, and be conducive to
The centralized processing of lime-ash.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
