Description
Technical field
This utility model relates to thermal power plant slag removal equipment, specifically a kind of slag crusher.
Background technology
Slag crusher is the equipment that slag removal system of thermal power plant must be used, and being used for crushing material bigger for granule is grain
The material that footpath is less.But existing slag crusher grinding, roll material time, because of rotating shaft high speed rotating, rotating shaft is the most overheated, from
And shorten slag crusher service life.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of good heat dissipation effect, the slag crusher of length in service life.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of slag crusher, including housing,
Stator and rotor, described stator is fixed in housing, rotates, described rotor bag in described rotor is arranged on stator and in stator
Including rotating shaft and the impeller being sleeved in rotating shaft, there are cooling water pipeline, described leaf in the inside of described rotating shaft along the axially arranged of rotating shaft
That takes turns is circumferentially provided with arc shaped blade.
Further, described stator includes that ring skeleton and grizzly bar, described grizzly bar are embedded in ring skeleton.
Further, the blade quantity on described impeller is three.
Further, the transverse section of described grizzly bar is triangle.
Further, the material of described arc shaped blade is diamond.
Further, the thickness of described arc shaped blade is radially gradually reduced along impeller.
The beneficial effects of the utility model are: by arranging axial cooling water pipeline inside rotating shaft, can make disintegrating slag
Machine is dispelled the heat when running, it is to avoid it is overheated, and the blade of impeller is arc, by cutting way rather than roll mode, subtracts
Vanelets and the contact area of material, relatively big due to percentage of blade surface area while reducing heat production, rapid heat dissipation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the slag crusher of this utility model embodiment.
Fig. 2 is the structural representation of the slag crusher of this utility model embodiment.
Label declaration:

Road.
Detailed description of the invention
By describing technology contents of the present utility model in detail, being realized purpose and effect, below in conjunction with embodiment and join
Conjunction accompanying drawing is explained.
The design of this utility model most critical is: by arranging axial cooling water pipeline inside rotating shaft, can make broken
Slag machine is dispelled the heat when running, it is to avoid it is overheated, and the blade of impeller is arc, by cutting way rather than roll mode,
Reduce the contact area of blade and material, relatively big due to percentage of blade surface area while reducing heat production, rapid heat dissipation.
Refer to Fig. 1 and Fig. 2, a kind of slag crusher, including housing 1, stator and rotor, described stator is fixed in housing,
Rotating in described rotor is arranged on stator and in stator, described rotor includes rotating shaft 32 and the impeller 31 being sleeved in rotating shaft,
There is cooling water pipeline 33 inside of described rotating shaft along the axially arranged of rotating shaft, described impeller be circumferentially provided with arc shaped blade 311.
Knowable to foregoing description, the beneficial effects of the utility model are: by arranging axial cooling inside rotating shaft
Waterpipe, can make slag crusher be dispelled the heat when running, it is to avoid it is overheated, and the blade of impeller is arc, by cutting way
It not the mode of rolling, reduce the contact area of blade and material, relatively big due to percentage of blade surface area while reducing heat production, heat radiation
Hurry up.
Further, described stator includes ring skeleton 21 and grizzly bar 22, and described grizzly bar is embedded in ring skeleton.
Seen from the above description, the Cracking Mechanism of this utility model slag crusher is cutting and rolls, after slag enters housing,
Enter cylindric bore of stator, by the impeller propelled of high speed rotating, along the inwall of stator with impeller together high speed rotating, arc
The slag in blade front is under the influence of centrifugal force by grizzly bar grinding, and the slag near blade edge is then cut by blade and breaks
Broken, the fine slag after being broken releases bore of stator under the wind-force that impeller produces, and from slag crusher under wind-force and action of gravity
Feed opening discharge.
Further, the blade quantity on described impeller is three.
Seen from the above description, blade quantity is 3, slag can be made to be ground by it well in stator, blade simultaneously
Between be not likely to produce resonance.
Further, the transverse section of described grizzly bar is triangle.
Seen from the above description, the transverse section of grizzly bar is triangle, and wedge angle is outwardly so that be cut or stove after grinding
The gap that slag is easier between grizzly bar out, is difficult to block.
Further, the material of described arc shaped blade is diamond.
Seen from the above description, use diamond material to make arc shaped blade, and the thickness of blade is along impeller the most gradually
Reducing so that the edge of arc shaped blade is the sharpest, stock-removing efficiency is high.
Refer to Fig. 1 and Fig. 2, embodiment of the present utility model is: a kind of slag crusher, including housing 1, stator and rotor,
Described stator is fixed in housing, rotates in described rotor is arranged on stator and in stator, and described rotor includes rotating shaft 32 He
The impeller 31 being sleeved in rotating shaft, there is cooling water pipeline 33 inside of described rotating shaft along the axially arranged of rotating shaft, described impeller
It is circumferentially provided with arc shaped blade 311.Described stator includes ring skeleton 21 and grizzly bar 22, and described grizzly bar is embedded in ring skeleton
In.Blade quantity on described impeller is three.The transverse section of described grizzly bar is triangle.
In sum, having the beneficial effects that of the slag crusher that this utility model provides: by arranging inside rotating shaft axially
Cooling water pipeline, slag crusher can be made to be dispelled the heat when running, it is to avoid it is overheated, and the blade of impeller is arc, by cutting
Mode rather than roll mode, reduces the contact area of blade and material, relatively big due to percentage of blade surface area while reducing heat production,
Rapid heat dissipation；Blade quantity is 3, slag can be made to be ground by it well in stator, be not likely to produce resonance simultaneously between blade；
The transverse section of grizzly bar is triangle, and wedge angle is outwardly so that be cut or between slag after grinding is easier between grizzly bar
Gap out, is difficult to block；Use diamond material to make arc shaped blade, and the thickness of blade is radially gradually reduced along impeller, makes
The edge obtaining arc shaped blade is the sharpest, and stock-removing efficiency is high.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize the equivalents that this utility model description and accompanying drawing content are made, or be directly or indirectly used in relevant technology neck
Territory, is the most in like manner included in scope of patent protection of the present utility model.
