A kind of emery wheel cooled fluorine is moulded flour mill, comprises grinding wheel spindle, the middle part fixed installation emery wheel of described grinding wheel spindle; The two ends of described grinding wheel spindle are rotated by bearing and are arranged on the bearing block; Emery wheel inlet opening and emery wheel apopore that described emery wheel inside is provided with cooling chamber and is communicated with cooling chamber; The emery wheel of described grinding wheel spindle has a main shaft inlet opening with the part on a left side along the axle center, the emery wheel of grinding wheel spindle has a main shaft apopore with the part on the right side along the axle center, described main shaft inlet opening is communicated with the emery wheel inlet opening, and described main shaft apopore is communicated with the emery wheel apopore; The inlet of described main shaft inlet opening is connected water pump.
Described cooling chamber is the annular chamber concentric with emery wheel, and it is the thin dumbbell shaped in big centre, two ends, the left and right sides in the cross section along diameter;
Described emery wheel inlet opening and emery wheel apopore are communicated with the bigger part in cooling chamber two ends respectively;
Described emery wheel inlet opening and emery wheel apopore lay respectively at 12 directions and 6 directions of emery wheel.
The beneficial effects of the utility model are: establish cooling chamber in the emery wheel, feed the cold water that flows in the cooling chamber, played the emery wheel effect of cooling rapidly; Cooling chamber is the thin special shape in big centre, two, has increased the time that cold water stops in cooling chamber, has further improved cooling effect; Emery wheel inlet opening and emery wheel apopore are communicated with the bigger part in cooling chamber two respectively, and are oppositely arranged, and as much as possible separately the distance of the two makes and the stop that cold water is grown as far as possible to absorb more heat, improve heat absorption efficiency in cooling chamber.

The specific embodiment
Below in conjunction with accompanying drawing, a kind of emery wheel cooled of the utility model fluorine is moulded the preferred implementation of flour mill and is made detailed description:
As shown in Figure 1, the groundwork that this emery wheel cooled fluorine is moulded flour mill partly is emery wheel 6, emery wheel 6 is fixedly mounted on the middle part of grinding wheel spindle 2, the two ends of grinding wheel spindle 2 are rotatably assorted by ball bearing 3 and bearing block 4, grinding wheel spindle 2 is rotated by motor-driven, and then drive emery wheel 6 rotation at a high speed, finish fluorine and mould the dry grinding abrasive dust.
Grinding wheel spindle 2 is being installed the part of emery wheel 6 positions with a left side, offer a main shaft inlet opening 5 along its axle center, the cross section, hole of main shaft inlet opening 5 is circular, its center of circle is positioned on the axial line of grinding wheel spindle 2, grinding wheel spindle 2 is being installed the part of emery wheel 6 positions with the right side, offer a main shaft apopore 8 along its axle center, the cross section, hole of main shaft apopore 8 also is circular, and its center of circle is positioned on the axial line of grinding wheel spindle 2.
As shown in Figures 2 and 3, the inside of emery wheel 6 is the center with himself center of circle, offered the cooling chamber 7 of an annular, cooling chamber 7 is shaped as the thin and symmetrical dumbbell shaped in big centre, two ends, the left and right sides on section of diameter, emery wheel 6 inside offer emery wheel inlet opening 71 and emery wheel apopore 72, emery wheel inlet opening 71 is communicated with the left side major part of cooling chamber 7, inlet is located on the installing hole hole wall of grinding wheel spindle 2 at emery wheel 6 centers, emery wheel apopore 72 is communicated with the right major part of cooling chamber 7, exports on the installing hole hole wall of the grinding wheel spindle 2 that also is located at emery wheel 6 centers.Emery wheel inlet opening 71 and emery wheel apopore 72 lay respectively at 12 directions and 6 directions of emery wheel 6.
Emery wheel inlet opening 71 is connected with the right-hand member of main shaft inlet opening 5, and emery wheel apopore 72 is connected with the left end of main shaft apopore 8.The left end of main shaft inlet opening 5 is connected water pump 1, and the outlet pipe of water pump 1 is embedded in the left end of main shaft inlet opening 5 and supplies water in the hole, and the right-hand member of main shaft apopore 8 is connected drainpipe, and drainpipe is enclosed within outward on the grinding wheel spindle 2.
When this emery wheel cooled fluorine was moulded flour mill work, emery wheel 6 produced high temperature owing to rotate dry friction at a high speed, and heat is passed to grinding wheel spindle 2 by emery wheel 6, again to bearings at both ends 3 direction transmission; The water pump 1 of high pressure is evacuated to cold water in the main shaft inlet opening 5, cold water is in emery wheel inlet opening 71 enters cooling chamber 7, high speed rotation along with emery wheel 6, cold water is under action of centrifugal force, on the long-time roof attached to cooling chamber 7, the very first time absorbs most of heat that emery wheel 6 produces, reached the purpose of rapid cooling, under the effect of high-pressure hydraulic pump 1, the cold water in the cooling chamber 7 is forced out from emery wheel apopore 72, discharges from main shaft apopore 8 again, when cold water flows through main shaft inlet opening 5 and main shaft apopore 8, absorb the heat on the grinding wheel spindle 2, guaranteed that heat transmits substantially less than bearing 3 places, has prolonged the service life of bearing 3 and grinding wheel spindle 2; Cooling chamber 7 adopts the thin shape in big centres, two ends, adds that emery wheel inlet opening 71 and emery wheel apopore 72 are oppositely arranged, and makes cold water greatly increase to the time of staying of discharging cooling chamber 7 from entering cooling chamber 7, has improved the cold water heat absorption efficiency, has saved the cold water resource.
