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
Put not give fat Novel rotary sealing valve.
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 body side plate, nipple, star-like rotor assembly, end cap composition separate cavities, power transmission shaft on star-like rotor assembly by installed in
In bearing on the end cap of valve body two ends, in order to ensure meet use environment in bearing separate cavities, it is necessary to by star-like rotor assembly with
Gap between valve body is sealed by sealing pair, while in separate cavities plus nitrogen or compressed air are sealed, make every
The pressure that air pressure is more than in valve pocket is sealed from intracavitary, prevents the coke powder in valve pocket from entering in separate cavities, existing dry coke quenching rotation
The sealing pair of sealing 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, by
In sealing pair it is 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 oil supply
Fat system goes wrong, and causes the temperature of valve body side plate too high after coke discharging temperature is too high, produced by badly influencing grease lubrication
Lubricating oil film, this will have a strong impact on the service life of sealing pair, use process, because coke blacking penetrates into sealing pair, sealing pair
Serious wear, steel ring press strip is easily deviate from, and causes equipment stuck, and sealing pair, coke breeze are close in sealing valve charging aperture two ends
Sealing pair is advanced to easily, sealing pair Fast Wearing is caused, and sealing pair service life is extremely low, and grease is costly, and grease is caused
Pollution environment, the CN202156737U announced for such as on 03 07th, 2012 is exactly typical this kind of design both at home and abroad at present；This
Bearing is displaced to outside separate cavities by the previous patent of inventor (LZ201520643298.8), using fan in separate cavities
Palace formula sealing pair is sealed, so as to cancel automatically to fat system, but easily enters coke powder in labyrinth type groove, close to labyrinth
The abrasion of by-product life is sealed, the star-like rotor assembly swell increment influenceed by coke discharging temperature is inconsistent, it is difficult to control concavo-convex labyrinth ring
Gap, easily produce card and relate to, the abrasion that the coke powder being accumulated in separate cavities is produced to the star-like rotor assembly that rotates for a long time,
The defect such as service life is short.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is that offer one kind need not be to fat, by non-
The secondary and a small amount of tolerance of contact seal carries out effective sealing gland, and the coke powder reduced in valve pocket enters in separate cavities, by fixed
Phase discharge avoids coke powder in separate cavities to the abrasion of the star-like rotor assembly rotated for a long time, eliminates to grease lubrication, this reality
New technique scheme is used, with potential faults are reduced, grease environmental pollution is solved, reduces use cost, it is ensured that equipment
Operation ratio, improves service life and temperature in use, technique effect easy to maintenance.
To achieve the above object, the utility model provides following technical scheme：Do not give fat Novel rotary sealing valve, bag
