Description
Technical field
The invention belongs to coking, metallurgy, cement equipment technical field, a kind of mineral aggregate, block, coke, sintering deposit be related to it both
Discharge, while the material discharger of sealing effectiveness is needed, more particularly to a kind of dry coke quenching, sintering, cement vertical mill discharge dress
The Novel rotary sealing valve put.
Background technology
The structure of existing rotary sealing valve in coke dry quenching includes valve body, star-like rotor assembly, charging aperture and discharging opening, by valve
Power transmission shaft on side plate, nipple, star-like rotor assembly, end cap composition separate cavities, star-like rotor assembly passes through installed in valve
In bearing on the end cap of body two ends, in order to ensure meeting use environment in bearing separate cavities, it is necessary to by star-like rotor assembly and valve
Gap between body is sealed by sealing pair, while adding nitrogen or compressed air to be sealed in separate cavities, makes isolation
Intracavitary sealing air pressure is more than the pressure in valve pocket, prevents the coke powder in valve pocket from entering in separate cavities, existing dry quenching rotary sealing
The sealing pair of valve leans on steel ring press strip clamping, and each steel ring press strip is divided into multistage, and whole circle is all compressed by steel ring press strip, due to sealing
Pair is to be pressed on by spring on valve body side plate end face, it is therefore desirable to permanently effective to be lubricated to grease, such as gives grease system
Go wrong, cause the temperature of valve body side plate too high after coke discharging temperature is too high, badly influence the lubricating oil produced by grease lubrication
Film, this will have a strong impact on the service life of sealing pair, use process, and because coke blacking penetrates into sealing pair, sealing pair abrasion is tight
Weight, steel ring press strip is easily deviate from, and causes equipment stuck, and sealing pair is close at sealing valve charging aperture two ends, and coke breeze just enters easily
Enter to sealing pair, cause sealing pair Fast Wearing, sealing pair service life is extremely low, and grease is costly, the pollution ring that grease is caused
Border, the CN202156737U announced for such as on 03 07th, 2012 is exactly typical this kind of design both at home and abroad at present；Before the present inventor
Bearing is displaced to outside separate cavities by one patent (LZ201520643298.8), and labyrinth sealing pair is used in separate cavities
Sealed, so as to cancel automatically to fat system, but easily enter coke powder, the mill given birth to labyrinth seal by-product in labyrinth type groove
Damage, the star-like rotor assembly swell increment influenceed by coke discharging temperature is inconsistent, it is difficult to the gap of concavo-convex labyrinth ring is controlled, easily production
Raw card is related to, and the abrasion that the coke powder being accumulated in separate cavities is produced to the star-like rotor assembly rotated for a long time, the short grade of service life lacks
Fall into.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide one kind noncontact need not be passed through to fat
Formula sealing pair and a small amount of tolerance carry out effective sealing gland, and the coke powder reduced in valve pocket enters in separate cavities, by periodically arranging
Put and avoid coke powder in separate cavities to the abrasion of the star-like rotor assembly rotated for a long time, eliminate to grease lubrication, skill of the present invention
Art scheme, with potential faults are reduced, solves grease environmental pollution, reduces use cost, it is ensured that equipment operation ratio, carry
High service life and temperature in use, technique effect easy to maintenance.
To achieve the above object, the invention provides following technical scheme：Do not give fat Novel rotary sealing valve, including valve body
With the star-like rotor assembly in valve body, described star-like rotor assembly is provided with power transmission shaft, and described power transmission shaft passes through valve body
