Abstract
The utility model provides a found bearing cooling device who grinds selection powder machine, include and separate heat exchanger and breather pipe, it installs the outside at the bearing frame to separate heat exchanger to the thermal -insulated space that forms with the outside hub of bearing frame, the one end and the outside intercommunication of breather pipe, the other end of breather pipe passes bearing frame and thermal -insulated space intercommunication, the breather pipe is two at least, has solved current found the selection powder machine that grinds the bearing application temperature is too high down, fragile and problem that life is short to improve the job stabilization nature and the reliability of a whole set of machinery.
Description
Technical field
The utility model relates to a kind of cooling device, especially a kind of bearing cooler of roller mill separator.
Background technology
The main shaft of roller mill separator is erect by upper and lower two pairs of bearings to be arranged in the housing of powder concentrator; that being wherein arranged on this main shaft bottom is all arranged in bearing block usually to bearing (lower bearing); this lower bearing and bearing block thereof are in powder concentrator powder air channel; like this; the wheel hub of powder concentrator lower bearing is surrounded by high-temperature gas, can transfer heat to bearing, makes bearing temperature higher; cause bearing to burn out, and then cause shutdown to stop production.In order to give the cooling of powder concentrator lower bearing, the method that usual employing improves the lubricating oil quality of this bearing, lubricants capacity and lubrication time or improves, can ensure that vertical mill system runs well at environmental protect temperature and lubrication nominal situation, but poor effect, every couple of days just there will be to be reported to the police to fall to stop and maintenance (or replacing) more than two hours of having to frequently stop to grind because of this Bearing Temperature, production of could again starting shooting when this bearing temperature is reduced to safe temperature.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of bearing cooler of roller mill separator, too high to solve existing roller mill separator lower bearing serviceability temperature, the problem that fragile and service life is short, thus the job stability and the reliability that improve a whole set of machinery.
The utility model solves the technical scheme that its technical problem adopts: a kind of bearing cooler of roller mill separator, comprise heat shield and breather pipe, described heat shield is arranged on the outside of bearing block, and the insulated space formed with the outside wheel hub of bearing block, one end of described breather pipe and ft connection, the other end of described breather pipe is communicated with insulated space through bearing block, and described breather pipe is at least two.
The utility model beneficial effect is:
1, reduce powder concentrator lower bearing temperature, the bearing cooler of this roller mill separator installs heat shield outside the bearing block of main shaft of roller mill separator lower bearing, this heat shield is connected outward with powder concentrator by breather pipe, powder concentrator internal negative pressure principle can be utilized like this, external environment gas is drawn in heat shield through breather pipe naturally this bearing is cooled, do not need external force that roller mill separator lower bearing environment can be made to obtain limited cooling.
2, owing to substantially prolongs the service life of lower bearing; because this reducing maintenance and the number of times changed and power generating ratio to the impact of producing; so decrease maintenance and device change the shutdown brought, the stability of whole production line and reliability are all largely increased.
Accompanying drawing explanation
fig. 1 is the utility model structural representation.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
The bearing cooler of a kind of roller mill separator as shown in Figure 1, a setting is had to be arranged on main shaft 1 in powder concentrator, with the lower bearing 2 and the bearing block 3 thereof that are arranged on main shaft 1 bottom, also comprise heat shield 4 and breather pipe 5, described heat shield 4 is arranged on the outside of bearing block 3, and the insulated space 6 formed with the outside wheel hub of bearing block 3, one end of described breather pipe 5 and ft connection, the other end of described breather pipe 5 is communicated with insulated space 6 through bearing block 3, and described breather pipe 5 is at least two.
Claims (1)
