Abstract
The utility model discloses a bearing seal device of a powder selecting machine, which comprises a bearing housing arranged inside a center cylinder of the powder selecting machine, transparent coversarranged at the two ends of the bearing housing, oil seals arranged inside the transparent covers, split-type oil seal gland bushes fixedly installed on the transparent covers, and split-type oil seals arranged inside the split-type oil seal gland bushes. The bearing seal device adopts the split-type oil seals to rapidly handle the oil leakage without the shaft removing, thereby facilitating themaintenance; split-type butter sleeves are fabricated at the upper parts of the oil seal gland bushes, packing is arranged at the upper part of the sleeves, and the sleeves are filled with butter, thereby isolating dust and prolonging the service life of the oil seals; a vent pipe is arranged in the center cylinder of the powder selecting machine to convert the central negative pressure to the positive pressure, thereby reducing the dust accumulation and further prolonging the service life of the oil seals; and with the bearing seal device, the site environment of the powder selecting machineis greatly improved, the consumptions of an oil product and an oil pump are greatly reduced, and the operating rate is increased to above 90%. The bearing seal device is also applied to machines suchas raw mill powder selecting machines, coal mill separators and the like with remarkable effect.
Description
Technical field
The utility model relates to a kind of powder concentrator that is used to produce cement, particularly a kind of powder concentrator associated sealing arrangement for bearings.
Background technology
At present, N3500 rotor of powder separator diameter 3500mm, setting height(from bottom) 36m, main shaft and rotor weigh 7.6 tons, the employing Lubricating-oil Station is lubricated, and it is 105～175T/h that cement selects powder yield, and its base bearing is in the powder concentrator enclosure interior, central negative pressure during the powder concentrator operation, main bearing seat is in the middle of the cement flour, and saturating lid is installed at two ends, is provided with oil sealing in the saturating lid, cover the installation gland thoroughly, be provided with packing_seal in the gland.Because work under bad environment, oil sealing often damages, and the average life span of oil sealing was at 3～5 months.It is very serious that oil sealing damages back powder concentrator leakage of oil, causes on-the-spot pollution thus, ecological deterioration.More than 400 kilograms of the losses every month of oil.The damage of oil sealing also causes bearing wear, and Lubricating-oil Station is brought in oil return into, oil pump heavy wear, and frequent the replacing, system shutdown, output descends.Change oil sealing, need pull down main shaft and rotor, need hundred tons of cranes, stop production at least more than the two weeks, inconvenient maintenance, required expense is higher.
Summary of the invention
The utility model provides a kind of powder concentrator associated sealing arrangement for bearings for solving the technical problem that exists in the known technology, and this device not only can prolong the life-span of oil sealing, and easy to maintenance.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of powder concentrator associated sealing arrangement for bearings, comprise the bearing block that is installed in the powder concentrator central tube, the bearing block two ends are equipped with lid, be provided with oil sealing in the saturating lid, cover thoroughly and be installed with the dissection type oil sealing cover, be provided with the dissection type oil sealing in the described dissection type oil sealing cover.
The utility model can also adopt following technical measures:
Above-mentioned powder concentrator associated sealing arrangement for bearings, be characterized in: described covering is connected with dissection type butter sleeve, described butter upper cartridge is the torus of threaded shaft, described torus inner circumferential is provided with and the contacted packing_seal circle of axle, described butter sleeve is provided with oil filler point, is marked with butter in the described butter sleeve.
Above-mentioned powder concentrator associated sealing arrangement for bearings is characterized in: described powder concentrator central tube is equipped with and is communicated with the inside and outside ventilation duct of powder concentrator.
Above-mentioned powder concentrator associated sealing arrangement for bearings is characterized in: install the dissection type gland on the described dissection type oil sealing cover, be provided with the packing_seal circle in the described dissection type gland.
Advantage and the good effect that the utlity model has are: adopt the dissection type oil sealing, can be under the situation of not taking out axle, and the fast processing leakage of oil, easy to maintenance; Made dissection type butter sleeve on oil sealing cover top, upper cartridge adds packing, fills stagnant butter in the sleeve, and isolated dust enters, and has prolonged the life-span of oil sealing; The powder concentrator central tube is equipped with ventilation duct, and central negative pressure is become malleation, reduces the accumulation of dust, has further prolonged the life-span of oil sealing; In a word, use the utility model, the powder concentrator site environment is greatly improved, oil product, oil pump consumption reduce greatly, the operation rate is brought up to more than 90%, and the utility model can also be applied on types such as raw mill powder concentrator, coal mill separator, and effect is remarkable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, gland, 2, packing, 3, oil sealing cover, 4, the subdivision oil sealing, 5, go up saturating lid, 6, nut, 7, bearing, 8, saturating lid down, 9, gland, 10, sleeve, 11, packing, 12, oil filler point, 13, bearing block, 14, central tube, 15, ventilation duct.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the right-hand part of Fig. 1 is a structure of the present utility model, the left side is a prior art constructions, analyze prior art bearing block position and structure, bearing block 13 is installed in the central tube 14 of powder concentrator, and wind speed is bigger in the powder concentrator, the center is a negative pressure, dust stratification buries bearing block, and the main shaft rotation is ground bearing seal bad, and the main shaft damage causes leakage of oil.Adopt the dissection type oil sealing at the problems referred to above, can be under the situation of not taking out axle, the fast processing leakage of oil.The utility model utilizes former bearing block bolt, cancelled former packing gland 9, made dissection type oil sealing cover 3, oil sealing cover 3 is assembled by two lobe splits, gland 3 installed inside subdivision oil sealing 4, made dissection type butter sleeve 10 on oil sealing cover 3 tops, the subdivision body of butter sleeve 10 is fixedly connected by the connecting plate of both sides.Butter sleeve 10 tops are the torus of threaded shaft, and the torus inner circumferential is provided with and contacted packing 11 of axle and sealing, and sleeve 10 interior filling by oil filler point 12 are added butter, and isolated dust enters.In service, butter in the butter sleeve 10 were changed oil, clean in per 3 months and can guarantee operation.Site environment greatly improves, and oil product, oil pump consumption reduce greatly.For further isolated dust enters dissection type oil sealing 4, can on dissection type oil sealing cover 3, install dissection type gland 1, be provided with packing 2 in the dissection type gland 1.Above-mentioned oil sealing cover 3 is fixed on and covers on 5, goes up saturating lid 5 and is fixed on the bearing block 13, and bearing 7 is installed in the bearing block 13, and top bearing 7 is by nut 6 lockings, and following bearing 7 is by down saturating lid 8 axial location.Because the lower end of bearing block 13 is positioned at the housing outside of powder concentrator, dust seldom can not add the butter sleeve, and other structures are identical with the upper end of bearing block 13.
In order further to improve the running rate of powder concentrator, on the central tube 14 of powder concentrator,, central negative pressure is become malleation to machine by two ventilation ducts 15 have been installed in the machine, reduce the accumulation of dust.
