Abstract
The utility model discloses a grinding roller sealing device for a vertical roller mill, which comprises a shaft sleeve fixed on a grinding roller shaft and a transparent cover arranged on the shaft sleeve in a sleeving manner. Two oil seals are arranged between the transparent cover and the shaft sleeve; a check block arranged on the shaft sleeve in a sleeving manner is arranged outside the two oil seals; and the check block is fixedly arranged on the transparent cover. The grinding roller sealing device for the vertical roller mill is characterized in that a check ring is arranged outside the check block; the check ring is fixed on the shaft sleeve; and a V-shaped sealing ring is arranged between the check ring and the check block. The grinding roller sealing device for the vertical roller mill not only can stop outside dust from entering a grinding roller, but also can block lubricating oil in the grinding roller from outflowing; the grinding roller sealing device for the vertical roller mill has a simple and compact structure, is firm and reliable, has good sealing performance and a long service life, is convenient for manufacturing and alignment in the installing process and has a certain adaptability to both vibration of the vertical mill and eccentricity of the shaft sleeve; and loss of a great amount of lubricating oil, pollution and shutdown of the mill, which are caused by oil leakage of the grinding roller, can be avoided, effective operating efficiency of the vertical mill is greatly improved, and substantial maintenance cost can be saved.
Description
Technical field
The utility model relates to a kind of grinding and grinding equipment of non-metal solid material, particularly relates to a kind of vertical roller grinder grinding-roll sealing device.
Background technique
At present, a kind of energy-conservation milling equipment that generally is used for the industries such as cement, iron and steel, electric power, chemical industry, mining is Vertical Mill, but because the damage of grinding roller of vertical mill sealing causes the phenomenon of grinding roller leakage of oil that generation is often arranged, not only bring the troubles such as replacing, maintenance to the user, also can therefore cause Vertical Mill to stop production simultaneously, cause certain economic loss.
Summary of the invention
The utility model provides a kind of good sealing effect, the vertical roller grinder grinding-roll sealing device of long working life for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of vertical roller grinder grinding-roll sealing device, comprise the axle sleeve that is fixed on the grinding roller roll shaft and the transparent cover that is sleeved on the axle sleeve, between described transparent cover and described axle sleeve, be provided with the twice oil sealing, be provided with the block that is sleeved on the described axle sleeve in the outside of the described oil sealing of twice, described block is packed on the transparent cover, the outside of described block is provided with back-up ring, described back-up ring is fixed on the described axle sleeve, is provided with v-ring between described back-up ring and described block.
Described v-ring is fixed on the described block.
Described back-up ring adopts jackscrew to be fixed on the described axle sleeve.
Advantage and the good effect that the utlity model has are: by be covered with dust structure with oil sealing combination of employing, can stop entering of external dust, outflow that again can shutoff grinding roller internal lubrication oil; And can protect V-shaped seal ring and first oil sealing not to be damaged by passing into lubricating grease.The utility model is simple in structure, compact, solid and reliable, good seal performance, and long service life is convenient to make and centering is installed, and the vibration of Vertical Mill and the off-centre of axle sleeve are all had certain adaptability; Can avoid greatly having improved effective running rate of Vertical Mill because lubricant oil that the grinding roller leakage of oil causes loses in a large number, pollution and grinding machine stop production, can save considerable maintenance cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, axle sleeve, 2, jackscrew, 3, back-up ring, 4, v-ring, 5, block, 6, oil sealing, 7, spacer ring, 8, transparent cover, 9, roll shaft.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of vertical roller grinder grinding-roll sealing device, comprise the axle sleeve 1 that is fixed on the grinding roller roll shaft 9 and the transparent cover 8 that is sleeved on the axle sleeve 1, between transparent cover 8 and axle sleeve 1, be provided with twice oil sealing 6, between twice oil sealing 6, be provided with spacer ring 7, be provided with the block 5 that is sleeved on the axle sleeve 1 in the outside of twice oil sealing 6, block 5 is packed on the transparent cover 8, the outside of block 5 is provided with back-up ring 3, back-up ring 3 adopts jackscrew 2 to be fixed on the axle sleeve 1, be provided with v-ring 4 between back-up ring 3 and block 5, v-seal 4 is fixed on the block 5.
During installation, at first axle sleeve 1 is enclosed within on the roll shaft 9, and at transparent cover 8 interior placement twice oil sealings 6, makes and form counterrotating slip surface between axle sleeve 1 and the oil sealing 6.V-shaped seal ring 4 of insert on the block in the transparent cover outside is fixed with back-up ring 3 and jackscrew 2.
Working principle of the present utility model:
Vertical Mill is when operation, and axle sleeve and oil sealing on the grinding roller relatively rotate, and the twice oil sealing is tightly embraced axle sleeve, stops the inner thin oil that is used for lubricating bearings of grinding roller to leak.Utilize one V-shaped seal ring to stop that external dust and foreign matter enter in the outside of transparent cover.In case V-shaped seal ring damages, the first oil sealing that is arranged on the outer end also can block entering of dust.After equipment is installed; should be in the middle of twice oil sealing and spacer ring and the V-shaped seal ring place be coated with full lubricating grease; the function of lubricating grease is to make between axle sleeve and the oil sealing and forms the oil film protection between V-shaped seal ring and the back-up ring; reduce friction factor, with the part injury of avoiding causing because producing the dry friction heating between the two.This novel grinding-roll sealing device by being covered with dust and combining with oil sealing, compact structure, sealing effect is good, has solved the difficult problem of the frequent leakage of oil of grinding roller, when the Vertical Mill running rate is improved greatly, also reduced by a considerable economic loss because keeping in repair and stopping production and cause for the user.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
