Abstract
The utility model discloses a rolling bearing type cement mill, a main milling device applied on a novel dry type cement production line. In the technical scheme, a feeding hollow shaft and a discharging hollow shaft are respectively provided with a double-row aligning roller bearing. The double-row aligning roller bearings are adopted instead of the existing slipper bearing. Since sliding friction is replaced by rolling friction, significant energy-saving effect can be achieved during operation. The water cooling system of the prior art is maintained, and a thin oil station is additionally arranged to lubricate the rolling bearing. Therefore, the rolling bearing type cement mill has a simple and reasonable structure, the vibration and wear of the parts of the rolling bearing type cement mill can be reduced, the operating efficiency of the rolling bearing type cement mill can be increased, the maintenance rate of the rolling bearing type cement mill can be decreased, and the service life of the rolling bearing type cement mill can be prolonged.
Description
Technical field
The utility model relates to a kind of main milling equipment that is used for new type nonaqueous cement production line, especially a kind of rolling bearing cement mill.
Background technology
The cement mill of Φ 4.2 rice diameters and above specification is the main milling equipment of new type nonaqueous cement production line, and cement grinding is the finishing operation that cement is made, and also is the maximum operation of power consumption.Its major function is clinker (reaching gelling agent, performance adjustment material etc.) grinding to suitable granularity (with fineness, expressions such as specific areas), form certain grain composition, increase its aquation area, quicken hydration rate, satisfy the cement slurry requirement of condensing, harden.
Because cement mill is to large scale development, its bearing load is also more and more big, and hot stream temperature is high again, generally uses the crawler shoe supporting on the large-scale cement mill.Slide shoe bearing since wheel band and the machining accuracy of carrying out watt and roughness are required tighter, thereby than cost height with base bearing supporting grinding machine.The structure of slide shoe bearing and safeguard more complicated in case certain link breaks down in the system, requires in time to find and repair, otherwise will influence the normal operation of whole grinding machine.And owing to be sliding friction, grinding machine starting energy consumption is bigger.
The utility model content
The purpose of this utility model provides a kind of rolling bearing cement mill, and this grinding machine can overcome above-mentioned the deficiencies in the prior art, and is simple and reasonable, and long service life replaces sliding friction with rolling friction, can save energy.
The technical solution adopted in the utility model is for achieving the above object:
The utility model comprises feed arrangement 1, live bearing device 3, charging quill shaft 4, cylindrical shell 5, discharging quill shaft 7, rigid bearing device 8, drawing mechanism 9, diaphragm coupling 10, center transmission speed reducer 11 and motor 12, it is characterized in that: a double-row self-aligning roller bearing 2 and 6 respectively are installed on charging quill shaft 4 and discharging quill shaft 7.
Double-row self-aligning roller bearing 2 and 6 internal diameters installed reach 2.25 meters.
Double-row self-aligning rolling bearing hot jacket is on quill shaft, and inner ring is fixed with two and half locating rings, stops the axial displacement of bearing, and bearing outer ring is fixed in the bearing groove of bearing block.
The utility model has been installed ultra-large type double-row self-aligning rolling bearing at the charging and discharging quill shaft, and it is to replace former existing slide shoe bearing with the double-row self-aligning rolling bearing, owing to replace sliding friction with rolling friction, makes it the obvious energy-saving effect that has been in operation.Promptly kept the prior art water-cooling system, increased Lubricating-oil Station again and lubricated rolling bearing, made it simple and reasonable for structure, and can reduce vibration, reduce parts depreciation, improve running efficiency, its maintenance rate reduces, prolong service life, and power savings is more obvious, generally can reduce power consumption 10～20%.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed narration.
As shown in Figure 1, the rolling bearing cement mill comprises feed arrangement 1, ultra-large type double-row self-aligning rolling bearing 2, live bearing device 3, charging quill shaft 4, cylindrical shell 5, ultra-large type double-row self-aligning rolling bearing 6, discharging quill shaft 7, rigid bearing device 8, drawing mechanism 9, diaphragm coupling 10, center transmission speed reducer 11, motor 12.Motor 12 is by center transmission speed reducer 11, drive charging quill shaft 4, cylindrical shell 5 and 7 rotations of discharging quill shaft through diaphragm coupling 10, ultra-large type double-row self-aligning rolling bearing 2 hot jacket charging quill shafts 4 are installed on the live bearing device 3, ultra-large type double-row self-aligning rolling bearing 6 hot jacket discharging quill shafts 7 are installed on the rigid bearing device 8, feed arrangement 1 is installed in charging quill shaft 4 one ends, and drawing mechanism 9 is installed in discharging quill shaft 7 one ends.Be illustrated in figure 2 as charging quill shaft, ultra-large type double-row self-aligning rolling bearing, live bearing device installation diagram.Be illustrated in figure 3 as discharging quill shaft, ultra-large type double-row self-aligning rolling bearing, rigid bearing device installation diagram.
Ultra-large type double-row self-aligning rolling bearing 2 hot jackets are on quill shaft, and inner ring is fixed with two and half locating rings, stop the axial displacement of bearing, and bearing outer ring is fixed in the bearing groove of bearing block.Because pulverizing cement produces a large amount of heats, bearing adopts the Lubricating-oil Station forced feed lubrication, passes to cooling water and cool off in bearing block.
The bearing arrangement of feed end is the live bearing device, and the roller that promptly has a row axially to roll along the charging quill shaft between bearing block and the base when the grinding machine expanded by heating or catch a cold when shrinking, can be done freely stretch to feed end.
The utility model embodiment is applicable to Φ 4.2 rice diameters and goes up the rolling bearing ball cement mill of specification, because adopt the rolling bearing ball mill of big specification, its economic benefit is more remarkable, generally calculate by falling energy consumption 10%, 4.2 * 14 meters rolling bearing ball mills of Φ use 3555 kilowatts of power, by 24 hours on the one, calculated, and can save: 3555 * 10% * 24 * 300=2559600 degree in 1 year 300 days.
