Description
Technical field
A vertical roll grinder grinding roller sealer with assembled, belongs to the vertical roll grinder field of grinding system in the industries such as building materials, electric power, mine, chemical industry, is specifically related to vertical grinding roller machine grinding-roll sealing device.
Background technique
At present, general grinding roller sealing device for vertical roller mill is by rocking arm, seal arrangement, seal ring forms, during work, by blower fan, provide pressurized gas, by the inlet hole on rocking arm, enter in seal arrangement, form continuously outside mobile air-flow, by the annular slot between fixing seal ring and rotating seal ring, spray, to stop the dust granules of grinding roller outside to enter in seal arrangement, but existing annular slot general control is between 2-5mm, dust granules is easy to enter in seal arrangement by annular slot, between grinding roller oil sealing cover and grinding roller axle sleeve, easily gather dust-laden greasy filth, the damage of aggravation grinding roller axle sleeve and oil sealing, and present oil sealing cover is non-adjustable, easily cause oil seal leak, moreover the frame of existing seal arrangement is all designed to an overall structure, can only when equipment rebuilding, take seal arrangement apart and carry out examination and maintenance, be unfavorable for the regular maintenance to seal arrangement, directly affected stability and the reliability of seal arrangement.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: a kind of vertical roll grinder grinding roller comprises shaft of grinding roller with sealer with assembled, rocking arm and seal arrangement form, it is characterized in that described seal arrangement comprises the oil sealing chamber that grinding roller axle sleeve and oil sealing base form, in-built a plurality of oil sealing and spacer ring, outer end fills the trim ring of adjustable compression oil sealing, interior ring dress " O " shape seal ring of trim ring, the cylindrical dress cylindrical of oil sealing base is step-like rotating seal ring, the in-built inner circle of frame is step-like fixing seal ring, fixing seal ring and rotating seal ring form labyrinth channel, during grinding roller work, pressurized gas enters in seal arrangement by the inlet hole on rocking arm, forming continuously outside mobile air-flow outwards sprays through labyrinth channel, the dust granules that wish is entered to seal arrangement by labyrinth channel stops beyond labyrinth channel, play good seal action, frame is provided with a plurality of peep holes can check at any time the sealing situation of oil sealing when shutting down, if there is the housing screw of the adjustable trim ring of oil sealing seepage, makes trim ring compress oil sealing.
Described shaft of grinding roller is provided with spill port, when lubricant oil enters into oil sealing when indoor, can flow back into lubricating loop by spill port, to stop outflow of lubrication oil seal arrangement to form, reveals.
Described trim ring is two half-turns, to facilitate installation " O " shape seal ring.
Bonding composition when described " O " shape seal ring is Assembling.
Compared with prior art, the beneficial effect that a kind of vertical roll grinder grinding roller of the present invention has with sealer with assembled is:
1, on shaft of grinding roller, establish spill port, make to enter the indoor lubricant oil of oil sealing and be back to rapidly lubricating loop, prevent that outflow of lubrication oil seal arrangement from causing leakage.
2, " O " the shape seal ring in trim ring and oil sealing form multiple-sealedly, and trim ring can adjust the compression degree of oil sealing at any time, can effectively stop oil leak.
3, labyrinth channel can effectively stop dust granules to enter in seal arrangement, prevents wearing and tearing and the inefficacy of seal arrangement.
4, peep hole can carry out examination and maintenance to seal arrangement in of short duration stopping process, can find early the generation of Burnisher apparatus fault, improves operation rate, reduces equipment maintenance cost, improves stability and the reliability of seal arrangement.
Accompanying drawing explanation:
Fig. 1 is the structural representation of sealer with assembled for a kind of vertical roll grinder grinding roller of the present invention.
Wherein: 1, inlet hole 2, roller mill axle sleeve 3, shaft of grinding roller 4, " O " shape seal ring 5, trim ring 6, oil sealing 7, spacer ring 8, rotating seal ring 9, spill port 10, fixing seal ring 11, oil sealing base 12, rocking arm 13, peep hole 14, housing screw 15, frame 16, labyrinth channel.
Embodiment
Fig. 1 is the most preferred embodiment of sealer with assembled for a kind of vertical roll grinder grinding roller of the present invention, and below in conjunction with accompanying drawing 1, the present invention will be further described.
With reference to Fig. 1: a kind of vertical roll grinder grinding roller sealer with assembled, comprise shaft of grinding roller 3, rocking arm 12 and seal arrangement form, it is characterized in that described seal arrangement comprises that roller mill axle sleeve 2 and oil sealing base 11 form oil sealing chamber, in-built a plurality of oil sealing 6 and spacer ring 7, outer end fills the trim ring 5 of adjustable compression oil sealing 6, interior ring dress " O " shape seal ring 4 of trim ring 5, the cylindrical dress cylindrical of oil sealing base 11 is step-like rotating seal ring 8, the in-built inner circle of frame 15 is step-like fixing seal ring 10, fixing seal ring 10 forms labyrinth channel 16 with rotating seal ring 8, frame 15 is provided with a plurality of peep holes 13.
Described shaft of grinding roller 3 is provided with spill port 9, when lubricant oil enters into oil sealing when indoor, can flow back into lubricating oil path by spill port 9.
Described trim ring 5 is two half-turns, to facilitate installation " O " shape seal ring 4.
Bonding composition when described " O " shape seal ring 4 is Assembling.
Working principle and working procedure are as follows:
During shaft of grinding roller 3 work, by oil sealing base 11 driven rotary seal rings 8, rotate; rotating seal ring 8 forms labyrinth channel 16 with fixing seal ring 10; when pressurized air enters in seal arrangement by inlet hole 1; forming continuously outside mobile air-flow outwards sprays through labyrinth channel 16; the dust granules that wish is entered to seal arrangement by labyrinth channel 16 stops beyond labyrinth channel 16, and peep hole 13 can check at any time the sealing situation of oil sealing 6 when shutting down.
