Specific embodiment
As depicted in figs. 1 and 2, a kind of high pressure roller disintegrating machine, including feed arrangement, drawing mechanism 6, frame 1 and motor
4, frame 1 is provided with the first compression roller 2 and the second compression roller 3 being parallel to each other, and its shaft core position is fixed with interior all first respectively
The roll shaft 31 of roll shaft 21 and second, motor 4 by power transmission 41 connect the first roll shaft 21 one end, the first roll shaft 21 it is another
One end connects one end of the second roll shaft 31 by transmission device 8, make the first roll shaft 21 and the second roll shaft 31 and they be connected it is crowded
Pressure roller synchronization opposite direction rotating.
As shown in Figure 3 and Figure 4, transmission device 8 includes first idle pulley 81 and the second idle pulley 82 of engagement, the first roll shaft 21 with
Second roll shaft 31 fixes first gear 83 and second gear 48 respectively, and the first idle pulley 81 is engaged with fixed first gear 83, and second
Idle pulley 82 is engaged with second gear 48.
First roll shaft 21 and the second roll shaft 31 fix first gear 83 and second gear 48 by swelling disk respectively.
As shown in figure 1, feed arrangement includes feed pipe 5, feed pipe 5 is connected between the first compression roller 2 and the second compression roller 3
The upper end in gap, feed pipe 5 is provided with throttle plate 51 and lower throttle plate 52, and upper throttle plate 51 ends before shutdown, etc.
Shut down again after discharge nozzle is unstowed, it is ensured that No Load Start.The discharge adjustable amount of lower throttle plate 52, realizes that the roll gap set up can be obtained
To not only saturation but also only stifled feed, prevents from lacking material or supersaturation charging worn roll skin.
As shown in figure 1, drawing mechanism 6 connects the lower end in gap between the first compression roller 2 and the second compression roller 3.
Feed arrangement includes being arranged on the feed hopper of the top of feed pipe 5.
When gap enters iron block between the first compression roller 2 of regulation and the second compression roller 3, iron block can not be crushed, if
There is no protection device, the roller skin on the outside of pressure roller will be damaged.
As shown in figure 1, the size in order to adjust gap between the first compression roller 2 and the second compression roller 3, the first roll shaft 21 is consolidated
It is scheduled in frame 1, the second roll shaft 31 is located on the sliding part of frame 1, when it is slided on sliding part, the first compression roller can be adjusted
2 and second gap between compression roller 3 size.The secured adjusted device 7 of second roll shaft 31, adjusting means 7 is fixed in frame 1.
As shown in figure 5, adjusting means 7 includes hydraulic cylinder 72, the cylinder body of hydraulic cylinder 72 is fixed in frame 1, hydraulic cylinder
Piston 73 be fixedly connected connector 71, the bearing of connector 71 connects the second roll shaft 31.The second roll shaft of distance 31 of hydraulic cylinder 72 compared with
Pressure sensor is provided with the oil cylinder 74 of remote side, the oil inlet pipe of oil cylinder 74 is provided with oil pump 76, and the flowline of oil cylinder 74 is provided with valve
Door 75, pressure sensor is electrically connected with oil pump 76, valve 75.
Enter iron block during charging, the second roll shaft 31 to the lateral movement of hydraulic cylinder 72 1, now, lived by the pressure in oil cylinder 74
The extruding of plug 73 but pressure increase, and after pressure sensor data measured, open valve 75, and flowline in oil cylinder 74 is opened and let out
Pressure so that the second roll shaft 31 continues to retreat, after iron block passes through, pressure of second roll shaft 31 from material reduces so that the second roller
Axle 31 is returned, and the pressure in oil cylinder 74 reduces, and after pressure sensor data measured, closes valve 75, opens oil pump 76, makes oil cylinder
Pressure in 74 recovers, while the second roll shaft 31 returns to original position, after pressure sensor data measured, stops oil pump 76.This
Damage of sample when protecting charging into iron block to roller skin.
In order to prevent entering iron block during charging, charging conveying sets tramp iron separator, reduces the probability that iron block enters.
Its operation principle：
Proved through research practice, in material particles crushing process, the deformation for applying pure pressure and producing is to apply pure shear
Be deformed five times of shear force, energy consumption needed for material individual particle is crushed under high pressure 100-300Mpa is significantly less than traditional grinding
Energy consumption and individual particle high pressure are crushed and cannot realized in commercial scale.Only entering the crushing of the horizontal high voltage bed of material to material particles group just has
Practical significance, here it is the operation principle of high pressure roller.
When material is fed to gap between the first compression roller 2 and the second compression roller 3 from feed arrangement, two rely on roller
Two are horizontally mounted and the compression roller of synchronous opposite direction rotating enters the crushing of the horizontal high voltage bed of material, and what material was squeezed roller nibbles pressure, and material is received
To extruding force gradually increase, but pulverized and be squeezed into closely knit material and discharged from the drawing mechanism 6 under roller, this material cake is squeezed
Compressive Strength is very low, and hand twists with the fingers just broken, wherein containing a large amount of fine powders ,≤2.5mm's accounts for 60-70%, wherein coarse granule internal structure also by
, there are many micro-cracks in destruction, it is easy to further powder processed.
Its feature and summary item：
1st, feed hopper, bucket capacity >=3 cubic metre should be equipped with two bin level indicators（Single rod oscillatory type bin level indicator）
Control dispenser feed and stopping feed.
2nd, feed pipe, there is two throttle plates, and upper throttle plate ends before shutdown, waits discharge nozzle to stop again after unstowing
Machine, it is ensured that No Load Start.Lower throttle plate discharge adjustable amount, what is realized the available not only saturation of the roll gap set up but also only block up gives
Material, prevents from lacking material or supersaturation charging worn roll skin.
3rd, roller pressure regulation is moved.
4th, single motor connection a new generation TPB planet-gear speed reducers, are connected roller end axle with swelling disk, and reductor is singly
Side torque support arm bears torsion, and moment of torsion is passed in movable roll and keeps opposite synchronous by fixing roller by one group of floating gear.
This load mode escapable cost 25%, reduces by 40% floor space.
5th, key points for operation：
(1) feeding conveying system must be provided with tramp iron separator, it is ensured that without iron block in charging, to ensure not enter iron, should also set
Metallic element detector.Conveyer can be found and stopped when tramp iron separator fails, and remove metal piece.
(2) the work of efficient stable, it is necessary to assure feeding is continuous and has certain material pressure.
(3) feed size≤0.025D D-roll neck aniseed is more to impair smoothness of operation and weight roller shelling damage.
(4) No Load Start, feed well of being unstowed before parking.
(5) after shutting down, hydraulic system release should be made, grease up after a stoppage of every eight hours, and check gear shaft
The lubricating status for holding, and hydraulic electric appliance system should carry out installation and debugging Inspection and maintenance according to industry standard specification.
