Abstract
The utility model relates to a poor and the selection powder spindle holds cooling device that provides of cooling effect is held to current vertical roller mill separator selection powder spindle in the vertical roller mill field. Including the pivot, locate the outside bearing of pivot, be equipped with cooling device in the bearing outside, this cooling device has the cavity that holds the coolant liquid including locating the outside dissipating heat set of bearing in this dissipating heat set, be equipped with inlet and liquid outlet that the intercommunication holds the coolant liquid cavity on dissipating heat set, feed liquor pipeline, liquid outlet intercommunication drain pipe way are connected to the inlet. The utility model discloses simple structure is equipped with cooling device outward with the bearing, and during equipment operation, the water inlet lets in condenser tube, and the pond is got rid of with the cooling water to the delivery port, when the cooling water moves at equipment, circulates always, constantly takes the heat that the bearing produced out of equipment, makes the bearing not fragile, and product life is longer.
Description
Technical field
This utility model belongs to vertical mill field, the powder concentrator bearing cooler of more particularly, to a kind of vertical mill.
Background technology
Vertical mill separator is the part that vertical mill is used for selecting powder, and its operation principle is that inside has individual high-speed rotation
Rotor, using centrifugal principle, the material that vertical pulverizing grinds is screened.Equipped with the axis of rolling in the drive shaft of rotor
Hold, when rotor high-speed rotation, bearing can send amount of heat, if bearing temperature problem rises to a certain extent, will damage
Bad.Current technology is by grease-added to bearing, plays lubrication cooling effect, but if rotor speed is too fast, grease
Cooling-down effect be not fine, bearing is easily damaged.
Utility model content
The purpose of this utility model is providing for existing vertical mill separator powder concentrator bearing cooling effect difference
Plant powder concentrator bearing cooler.
To achieve these goals, technical solution adopted in the utility model is：
A kind of powder concentrator bearing cooler, the bearing outside including rotating shaft, located at rotating shaft, it is provided with cooling in Bearing outer
Device, this chiller includes the radiating sleeve located at Bearing outer, has the cavity accommodating coolant in this radiating sleeve, in radiating
Put the inlet being communicated with accommodating coolant cavity and liquid outlet, inlet connects input duct, liquid outlet connects out liquid
Pipeline.
Described radiating sleeve has and will accommodate the discharge outlet that coolant cavity is in communication with the outside, connect at discharge outlet
There is blocking, discharge outlet is located at the bottom of cavity.
Described radiating sleeve include the inner sleeve fitting tightly with bearing outer ring and be tightly connected with inner sleeve and with inner sleeve it
Between form the overcoat of cavity, discharge outlet puts located at outward.
Bearing includes upper bearing (metal) and lower bearing, is provided with the first oil filler on upper bearing (metal), is provided with and lower axle on radiating sleeve
Hold the second oil filler of connection.
The beneficial effects of the utility model：This utility model structure is simple, and bearing is externally provided with chiller, equipment operation
When, water inlet is passed through cooling water pipe, and cooling water drainage is removed pond by outlet, and cooling water, when equipment runs, circulates always, by axle
The heat holding generation constantly takes equipment out of, so that bearing is hardly damaged, and product service life is longer.
Brief description
Fig. 1 is sectional view of the present utility model.
Specific embodiment
With reference to embodiment, this utility model is described further.
Embodiment
A kind of powder concentrator bearing cooler as shown in Figure 1, the upper bearing (metal) 3 outside including rotating shaft 1, located at rotating shaft and under
Bearing 7, is externally connected to bearing block in two bearings, is provided with chiller outside two bearings seat, this chiller include located at
Radiating sleeve outside bearing block, has the cavity 6 accommodating coolant in this radiating sleeve, be communicated with accommodating cooling on radiating sleeve
The inlet 5 of sap cavity body and liquid outlet 9, inlet connects input duct, and liquid outlet connects drain pipe road.In described radiating sleeve
On have and will accommodate the discharge outlet 8 that is in communication with the outside of coolant cavity, be connected with blocking at discharge outlet, discharge outlet is located at cavity
Bottom.Described radiating sleeve include with bearing outer ring or bearing block outside the inner sleeve that fits tightly, also include and inner sleeve sealing
Overcoat that is connecting and forming cavity and inner sleeve between, discharge outlet puts located at outward.First oil filler 2 is provided with upper bearing (metal),
The second oil filler 4 being connected with lower bearing is provided with radiating sleeve.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, in the art commonly
The simple change of technical staff and replace be all within protection domain of the present utility model.
