The lower sealing ring includes sealing ring one and sealing ring two, and sealing ring one is fitted close and is arranged on the upper of sealing ring two
Portion；The section of the sealing ring one is rectangle, and sealing ring two includes section for two circular size identical seals；Institute
State the level match spread configuration of sealing ring two.
Oiling device is set on described in oil filler point, and oiling device includes the spring and steel installed in oil filler point bottom
Pearl, steel ball Matching installation are communicated in spring top, the bottom of oil filler point by oiling passage with bearing fit.
Beneficial effect：
Pass through the upper and lower sealing ring of setting, upper and lower sealing ring, upper and lower compressed air inlet, oil filler point；Add relevant device
Sealing, avoid coal dust from entering in the bearing of junction, and compressed air is passed through by compressed air inlet, make warehouse
The pressure of junction is more than the pressure in warehouse, avoids the coal dust in warehouse from entering in bearing.
Brief description of the drawings
Fig. 1 is the upper fixed warehouse of the present invention and the sealed structural representation of rotation warehouse；
Fig. 2 is the lower fixed warehouse of the present invention and the sealed structural representation of rotation warehouse.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present invention proposes a kind of sealing device for being applied to rotation cleaner, including the upper method installed in upper fixed warehouse 1
Upper sealing ring 3 between the outer rim 21 of orchid 11 and upper rotary support, outer rim 21 and the upper fixed warehouse 1 of upper rotary support
Outside upper steel ring 12 is equipped with upper sealing ring 4, oil filler point 5 is set on the top of upper flange 11, in the upper water of upper sealing ring 3
It is flat that upper compressed air inlet 8 is set；Set between the outer lower steel ring 62 of lower fixed warehouse 6 and the outer rim 22 of lower revolving support
Lower seal 10, the lower flange 61 of the outer rim 22 of lower revolving support and lower fixed warehouse 6 is equipped with lower sealing ring 15, under
The top of revolving support sets lower oil filler point, and compressed air entrance 9 is horizontally disposed with the lower side of lower flange 61.
Outside upper steel ring of the passage of the upper compressed air inlet 8 from the horizontal-extending supreme fixed bin body 1 of end inlets
Place, and the diameter of end inlets is more than the diameter inside passage；The passage of the upper compressed air inlet 8 edge at innermost end
Outside upper steel ring 12 rounds setting.
The passage of the compressed air entrance 9 extends straight up again after being run horizontally for some distance from end inlets
Rounded setting to the junction of outer rim 22 and the lower flange 61 of lower revolving support, and along lower flange 61.
The passage of the upper compressed air inlet 9 is located at the top of upper sealing ring 4.
It is located at the bottom of lower sealing ring 15 at the feeder connection of the compressed air entrance.
The lower sealing ring 15 includes sealing ring 1 and sealing ring 2 152, and sealing ring 1 is fitted close and is arranged on
The top of sealing ring 2 152；The section of the sealing ring 1 is rectangle, and sealing ring 2 152 includes section for circular two
Individual size identical seal；The level match spread configuration of sealing ring 2 152.
Oiling device is set on described in oil filler point 5, and oiling device includes the He of spring 52 installed in oil filler point bottom
Steel ball 51, the Matching installation of steel ball 51 are communicated in the top of spring 52, the bottom of oil filler point 5 by oiling passage with bearing fit.
Upper and lower revolving support, upper and lower warehouse, warehouse 13 is rotated, upper and lower flange is prior art device, and it passes through
Prior art is connected.The section of upper sealing ring 4 is in irregular abnormity, and upper compressed air inlet 9 passes through compressed air
Conveying so that the pressure outside warehouse is more than the pressure in warehouse, makes coal dust be not easily accessible at bearing.Compressed air inlet leads to
