Description
Technical field
It the utility model is related to the bearing seal ring of vertical spindle coal pulveriser, more particularly to vertical spindle coal pulveriser Burnisher apparatus.
Background technology
Grinding roller is the core component of grinding machine, is mainly made up of roller set, roller support, roll shaft, bearing block, bearing, oil sealing etc..It
Between mill and pressue device (pressure frame), positioned by pressure frame.During machine startup, come by seal fan close
The tunnels of Feng Fengfen tetra- reach grinding roller sealing, tie-rod sealing, separator sealing and lower frame sealing position.Seal and separate to lower frame
Butterfly valve is housed on device sealing pipeline, for distributing air quantity.Sealing air to grinding roller is entered in coal pulverizer by airduct outside separator,
Internally enter roller support further through air loop duct and three moveable vertical airducts equipped with joint ball bearing, when being milled with guarantee
Grinding roller swings the input for not influenceing sealing air with play.Because existing vertical spindle coal pulveriser Burnisher apparatus is using sealing air secret
Envelope, makes that its cost is higher, and sealing effectiveness is general.
Utility model content
The utility model is in order to solve problem of the prior art, there is provided and one kind has preferable sealing effectiveness, without using
Seal fan, effectively reduce the bearing seal ring of the vertical spindle coal pulveriser Burnisher apparatus of cost.
Concrete technical scheme is as follows：The bearing seal ring of vertical spindle coal pulveriser Burnisher apparatus, including main body, fixed part and inclination
Portion, the fixed part are arranged on main body one end, and main body is provided with stomata, and stomata connects with the cavity in the middle part of main body, the inclination
Portion is connected with main body, and rake is obliquely installed with respect to axis where main body, and the rake includes first end and the second end,
First, second end is located at main body both sides respectively, and the second end is located at below main body, and the second end has arcwall face.
It is attached technical scheme of the present utility model below.
Preferably, the radian of the arcwall face is 45 °.
Preferably, the fixed part is circle, and fixed part is provided with multiple mounting holes, and mounting hole is arranged in circle
Shape.
Preferably, the first end is cambered surface, and radian is 12 °.
Preferably, the bearing seal ring is set on bearing, has inlet chamber between stomata and bearing.
Technique effect of the present utility model：The bearing seal ring of vertical spindle coal pulveriser Burnisher apparatus of the present utility model can be adopted
Entered with air is introduced so as to cut off dusty gas inside grinding roller, protect grinding roller internal bearings, serve airtight effect；This
Outside, it can substitute seal fan of the prior art, effectively reduce cost.
Brief description of the drawings
Fig. 1 is the installation diagram of the bearing seal ring of the vertical spindle coal pulveriser Burnisher apparatus of the utility model embodiment.
Fig. 2 is the schematic diagram of the bearing seal ring of the vertical spindle coal pulveriser Burnisher apparatus of the utility model embodiment.
Fig. 3 is another schematic diagram of the bearing seal ring of the vertical spindle coal pulveriser Burnisher apparatus of the utility model embodiment.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
As shown in Figure 1 to Figure 3, the bearing seal ring 100 of the vertical spindle coal pulveriser Burnisher apparatus of the present embodiment includes main body 1,
Fixed part 2 and rake 3, the fixed part 2 are arranged on the one end of main body 1.Main body 1 is provided with stomata 11, stomata 11 with main body
The cavity 12 in portion connects.The rake 3 is connected with main body 1, and in the present embodiment, rake is to be wholely set with main body.Tilt
Portion 3 is obliquely installed with respect to axis where main body, and the rake 3 includes first end 31 and the second end 32, first, second end
Portion is located at the both sides of main body 1 respectively, and the second end 32 is located at below main body, and the second end 32 has arcwall face 321.Above-mentioned technical side
In case, grinder system is negative-pressure operation, and air A enters inside grinding machine and entered containing for sealing ring from the stomata 11 of bearing seal ring
Dust and gas body B meets, and enters so as to cut off dusty gas inside grinding roller, protects grinding roller internal bearings, serve airtight effect.Figure
Middle arrow refers to air A and dusty gas B respectively, consequently facilitating explanation gas trend.Pass through above-mentioned technical proposal, it can strengthen
The sealing effectiveness of Burnisher apparatus, reduces cost.
As shown in Figure 1 to Figure 3, further, the radian of the arcwall face is 45 °.The fixed part 2 is circle, fixed
Portion is provided with multiple mounting holes 21, and mounting hole 21 is arranged in circle, can be fixed bearing seal ring by mounting hole.Described first
End 31 is cambered surface, and radian is 12 °.The bearing seal ring is set on bearing 200, is had between stomata 11 and bearing 200
Inlet chamber 4.
The bearing seal ring of the vertical spindle coal pulveriser Burnisher apparatus of the present embodiment, which can use, introduces air so as to cut off dust-laden
Gas enters inside grinding roller, protects grinding roller internal bearings, serves airtight effect；In addition, it can be substituted in the prior art
Seal fan, effectively reduce cost.
It is pointed out that above-mentioned preferred embodiment is only to illustrate technical concepts and features of the present utility model, its purpose
It is to allow person skilled in the art to understand content of the present utility model and implements according to this, this reality can not be limited with this
