Description
Technical field
The present invention relates to medium-speed pulverizer sealing technique, especially a kind of drive plate sealing device.
Background technique
Medium-speed pulverizer is the main powder manufacturing apparatus of the industries such as current electric power, metallurgy, building materials chemical industry, is especially answered in thermal power plant
It is the important component part of power plant's pulverized coal preparation system with more extensive.Its main task is will to be ground into granular material to grind materials,
It is supplied to boiler plant.Therefore the work quality of medium-speed pulverizer directly affects the safety and economic benefit of entire unit, drive plate sealing
Device is the important moving component of medium speed mill, and drive plate is then the crux sealing position of medium-speed pulverizer.Currently used drive plate
It is sealed into carbon crystal sealing；When work, carbon crystal sealing and drive plate rigid contact.Abrasion and particle media because of carbon crystal sealing
The generation of intrusion and leakage, causes the ring packing air compartment wind pressure in grinding machine to be difficult to maintain, and particle media can be made to invade
More, the abrasion for aggravating intrusion and the carbon crystal sealing of particle media, finally results in carbon crystal seal failure.In conclusion existing
The abrasion of carbon crystal sealing is also easy to produce leakage, and sealing air compartment air loss rate is excessive, and sealing air compartment wind pressure is low；Occur so as to cause easy
The phenomenon that powder leakage, and then pollute the environment and equipment of production scene；In serious powder leakage, medium-speed pulverizer is unfavorable also by forced outage
In equipment reliability service and spare.
Summary of the invention
Present invention aim to solve problem above, a kind of drive plate sealing device is provided, can effectively solve existing
The defect of carbon crystal sealing, avoids and is easy to appear powder leakage phenomenon, ensure that the environment of production scene, extends equipment and uses the longevity
Life.
The technical scheme is that realized by following measures: a kind of drive plate sealing device, including pedestal, carbon
Crystalline substance sealing, carbon crystal seal outer ring；Its main feature is that: it is equipped with flexible seal ring in the bottom of carbon crystal sealing outer ring, in flexible seal ring
Bottom be equipped with cricoid metal sealing supporting plate, flexible seal ring be clipped in carbon crystal sealing outer ring and sealing supporting plate between, in flexibility
The outside of sealing ring is fixed on the bottom that carbon crystal seals outer ring for supporting plate is sealed with multiple bolts；Side ring surface is set in flexible seal ring
There are the flexible wear inner ring and multiple tracks circular ring shape oil storage tank, the inner ring surface of flexible wear inner ring and the outer shaft of pedestal of multiple tracks annular shape
Face is in close contact；Flexible seal ring is equipped with the opening being easily installed, and the outer ring surface opening lap-joint of flexible seal ring is equipped with flexibility
Sealing ring connector, the flexible seal ring connector are equipped with multiple inlet nozzles, each inlet nozzle and corresponding oil storage tank
Between be equipped with oil inlet pipe.
Further, the flexible seal ring outer surface, which is equipped with, pre-tightens becket.
Further, the multiple tracks oil storage tank is twice.
Further, the multiple tracks flexible wear inner ring is twice.
Further, the disconnected section of the flexible seal ring is " E " font.
The configuration of the present invention is simple, it is at low cost, efficiently solve big, the sealing that seals existing seal clearance of existing pedestal carbon crystal
Wind leakage rate is big；The problems such as solving powder leakage phenomenon, avoiding the environment and equipment of pollution production scene.
Detailed description of the invention
Fig. 1 is left half of schematic cross-sectional view of the invention.

Specific embodiment
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to Figure of description
Butut mode be described, such as: front, rear, top, and bottom, left and right positional relationship be the Butut according to Figure of description
Direction determines.
Below with reference to examples and drawings, the invention will be further described:
Fig. 3 is existing left half of schematic cross-sectional view.
As shown in Figure 1 and Figure 2, this drive plate sealing device includes pedestal 1, flexible seal ring 5, flexible wear inner ring 6, ring
The sealing supporting plate 9 of the metal of shape.Disconnected section is " inner arc surface of E " font flexible seal ring 5 is equipped with twice flexible wear inner ring
6, twice oil storage tank 8；Flexible seal ring is equipped with the opening being easily installed, and is equipped in the outer surface of flexible seal ring 5 and pre-tightens metal
The outer ring surface opening lap-joint of ring, flexible seal ring is equipped with flexible seal ring connector 11, on flexible seal ring connector 11
Equipped with multiple inlet nozzles 12, oil inlet pipe 7 is equipped between each inlet nozzle 12 and corresponding oil storage tank 8.
The setting of flexible seal ring 5 seals between outer ring 13 and sealing supporting plate 9 in carbon crystal, and carbon crystal seals outer ring 13 and sealing support
It is connected between plate 9 with bolt 10.
The disconnected section of oil storage tank 8 and flexible wear inner ring 6 is in "mouth" shape, and the inner arc surface of wear-resisting inner ring 6 is close to
1 outer cylinder of pedestal.
The flexible seal ring 5 of opening forms a full circle ring packet in pedestal 1 by the connection of flexible seal ring connector 11
Outside outer cylinder, and being close to reach and effectively prevent powder leakage existing by flexible wear inner ring 6 inside flexible seal ring 5 and pedestal 1
