Abstract
The invention discloses a crushing rotor with a cooling function. The crushing rotor comprises a main shaft; a plurality of hammer plates sleeve the main shaft in an axial direction; hammer holes are circumferentially and evenly formed in each hammer plate; a hammer shaft is connected in each hammer hole; a machine hammer sleeves each hammer shaft; a belt wheel is connected to one end of the main shaft, while a flywheel for balancing is connected to the other end of the main shaft; an axial cooling primary main line is arranged within the main shaft and comprises an inlet and an outlet, and the inlet and the outlet both are arranged at one end, close to the flywheel, of the main shaft; a cooling branch is arranged at the joint of the main shaft and each hammer plate; an annular cooling path is arranged inside each hammer plate in a circumferential direction; a cooling secondary main line is arranged within each hammer shaft in an axial direction and communicates with each annular cooling path through a connecting channel; by using the rotor, lots of friction heat generated at the joint of each machine hammer and each hammer shaft can be quickly reduced, and further, heat at the joint of each machine hammer and each hammer shaft can be bought away together, and therefore, the probability of thermal deformation and even breakage of the hammer shaft or the machine hammer can be reduced.
Description
Technical field
The present invention relates to field of cracking machine, be specifically related to the broken rotor with refrigerating function.
Background technology
Mine crushing machine is also stone crusher, refers to that content that granularity in discharge is greater than three millimeters accounts for the size reduction machinery of total withdrawal rate more than 50%; Mine crushing machine is widely used in numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.
Existing mine crushing machine comprises hammer mill, jaw crusher etc., wherein hammer mill primarily of broken casing, be positioned at broken casing top feed space, be positioned at the crushing chamber in the middle part of broken casing and be positioned at broken casing bottom screening room form, and the broken rotor in crushing chamber, be the core of disintegrating machine, broken rotor is under high-speed rotation, and make the volume machine hammer swing that rotor is rotationally connected, owing to being high velocity environment, the kinetic energy that machine is hammered into shape is large, carries out impact broken to the broken thing dropping into crushing chamber, but in actual use, find because hammer axle is rough, machine hammer is also rough with junction, hammer axle surface, when causing machine to hammer swing into shape, frictional force is large, in addition a large amount of dust can be produced in fragmentation, and these dust adhesion are on hammer axle, increase the roughness on hammer axle surface, the broken time all reaches several hours simultaneously, make machine hammer and hammer shaft connection place frictional heat into shape large, temperatures as high 300 DEG C, and under hammering axle and machine hammer into shape junction being in hot conditions for a long time, very easily cause hammer axle or the distortion of machine hammer, and then cause hammer axle or the fracture of machine hammer, cause the accident.
Summary of the invention
The invention is intended to provide the broken rotor with refrigerating function, solved machine hammer and hammer shaft connection place frictional heat, and heat cannot derive caused hammer axle or the distortion of machine hammer, the problem of the hammer axle caused or the fracture of machine hammer.
The broken rotor with refrigerating function in this programme, comprises main shaft, and described main shaft is axially socketed with some hammer plates, the circumference of hammer plate is evenly equipped with hammer hole, and hammer is connected with hammer axle in hole, and hammer axle is socketed organic hammer, be connected with belt wheel in main shaft one end, the main shaft other end is connected with the flywheel for balancing; Described main shaft inside is provided with axial cooling major trunk roads, and cooling major trunk roads comprise import and outlet, and import and outlet are all located at main shaft one end near flywheel, is provided with cools branch at main shaft and hammer plate junction; Described hammer intralamellar part and be circumferentially provided with annular cooling duct, inner and be axially provided with cooling subsidiary road on described hammer axle, described cooling subsidiary road is communicated with by interface channel with between annular cooling duct.
The operation principle of this programme and beneficial effect thereof:
By injecting cooling fluid in import in flowing cooling major trunk roads, and the cooling fluid that flows enters into annular cooling duct by cooling branch, flowing cooling fluid being dispersed at the interface channel by being connected with annular cooling duct hammers into shape in axle, cooling subsidiary road simultaneously in hammer axle is by the flowing cooling fluid come to interface channel, when flowing cooling fluid is hammered into shape by machine and hammers shaft connection place into shape, according to thermodynamics second theorem, frictional heat conducts in cryogenic liquid, and takes away with cooling fluid; And the route of cooling fluid in time coming taking away heat returns, heat is derived.Adopt this rotor, not only can reduce a large amount of frictional heats that machine hammer and hammer shaft connection place produce fast, the heat outside machine hammer and hammer shaft connection place also together can also be taken away, reduce hammer axle or the possibility that even ruptures of machine hammer thermal deformation.
Further, described import and outlet are equipped with bearing with main shaft junction, and bearing inner sleeve is connected to carrier pipe.Avoid carrier pipe to rotate, and then guarantee that the conveying of cooling fluid is stablized.
Further, described bearing is socketed with the shell for preventing cooling fluid from revealing.Cooling fluid is revealed, and the cooling liquid measure inputting rotor can be caused to reduce, cause the cooling fluid quantity not sufficient of internal rotor, makes tup with hammer shaft connection place because the heat produced that rubs cannot derive fast.
Further, described carrier pipe is connected with oil pump.By oil pump, cooling fluid is pressed into internal rotor, and then tup and the hammer axle heat produced that rubs are derived by cooling fluid.
