Detailed description of the invention
As depicted in figs. 1 and 2, a kind of high pressure roller disintegrating machine, comprise 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 be parallel to each other, its shaft core position is fixed with the first roll shaft 21 and the second roll shaft 31 respectively, motor 4 connects one end of the first roll shaft 21 by power transmission 41, the other end of the first roll shaft 21 connects one end of the second roll shaft 31 by transmission device 8, the synchronous opposite direction rotating of compression roller making the first roll shaft 21 and the second roll shaft 31 and connect respectively.
As shown in Figure 3 and Figure 4, transmission device 8 comprises the first idle pulley 81 and the second idle pulley 82 of engagement, first roll shaft 21 and the second roll shaft 31 are fixed the first gear 83 and the second gear 48, first idle pulley 81 respectively and are fixed the first gear 83 and engage, and the second idle pulley 82 engages with the second gear 48.
First roll shaft 21 and the second roll shaft 31 fix the first gear 83 and the second gear 48 respectively by swelling dish.
As shown in Figure 1; feed arrangement comprises feed pipe 5; feed pipe 5 connects the upper end in gap between the first compression roller 2 and the second compression roller 3; feed pipe 5 is provided with throttle plate 51 and lower throttle plate 52; upper throttle plate 51 ends before shutdown; wait for that discharge nozzle is shut down after unstowing again, guarantee No Load Start.Lower throttle plate 52 discharge adjustable amount, the roll gap realizing setting up can obtain not only saturated 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 comprises the feed hopper be arranged on above feed pipe 5.
When between adjustment first compression roller 2 and the second compression roller 3, gap enters iron block, iron block can not be pulverized, if do not have protective device, the roller skin outside pressure roller is by damaged.
As shown in Figure 1, in order to regulate the size in gap between the first compression roller 2 and the second compression roller 3, the first roll shaft 21 is fixed in frame 1, and the second roll shaft 31 is located on the sliding part of frame 1, when it slides on sliding part, the size in gap between the first compression roller 2 and the second compression roller 3 can be regulated.Second roll shaft 31 secured adjusted device 7, adjusting device 7 is fixed in frame 1.
As shown in Figure 5, adjusting device 7 comprises hydraulic cylinder 72, and the cylinder body of hydraulic cylinder 72 is fixed in frame 1, and the piston 73 of hydraulic cylinder is fixedly connected with connector 71, and connector 71 bearing connects the second roll shaft 31.Be provided with pressure sensor in the oil cylinder 74 of hydraulic cylinder 72 apart from the second roll shaft 31 side far away, 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 75, and pressure sensor and oil pump 76, valve 75 electrically connect.
Iron block is entered during charging, second roll shaft 31 is to hydraulic cylinder 72 1 lateral movement, now, pressure in oil cylinder 74 is subject to the extruding of piston 73 but pressure increase, after pressure sensor data measured, open valve 75, pressure release opened by flowline in oil cylinder 74, the second roll shaft 31 is made to continue to retreat, after iron block passes through, second roll shaft 31 reduces from the pressure of material, second roll shaft 31 is returned, pressure in oil cylinder 74 reduces, after pressure sensor data measured, valve-off 75, open oil pump 76, make the pressure recover in oil cylinder 74, second roll shaft 31 returns to original position simultaneously, after pressure sensor data measured, oil pump 76 is stopped.The damage of iron block pair roller skin is entered when protecting charging like this.
In order to prevent entering iron block during charging, charging conveying arranges tramp iron separator, reduces the probability that iron block enters.
Its operation principle:
Facts have proved after deliberation, to in material particles crushing process, apply pure pressure and the distortion that produces is five times that apply that pure shear shear force produces distortion, store list particle pulverizes under high pressure 100-300Mpa that required energy consumption is significantly less than the energy consumption of traditional grinding and the pulverizing of individual particle high pressure cannot realize in commercial scale.Only have to material particles group carry out the high pressure bed of material pulverize just have Practical significance, the operation principle of high pressure roller that Here it is.
When material is fed to gap between the first compression roller 2 and the second compression roller 3 from feed arrangement, two pair rollers rely on two levels to install and the compression roller of synchronous opposite direction rotating carries out the pulverizing of the high pressure bed of material, what material was squeezed roller nibbles pressure, the extruding force that material is subject to increases gradually, but pulverized and be squeezed into the drawing mechanism 6 of closely knit material from roller and discharge, this material cake crushing strength is very low, hand is twisted with the fingers just broken, wherein containing a large amount of fine powder, ≤ 2.5mm accounts for 60-70%, wherein coarse granule internal structure is also destroyed, and there is many micro-cracks, is easy to further powder process.
Its feature and summary item:
1, feed hopper, bucket capacity >=3 cubic metre, should be equipped with two bin level indicators (single excellent oscillatory type bin level indicator) and control dispenser feed and stop feed.
2, feed pipe, have two throttle plates, upper throttle plate ends before shutdown, waits for that discharge nozzle is shut down after unstowing again, guarantees No Load Start.Lower throttle plate discharge adjustable amount, the roll gap realizing setting up can obtain not only saturated but also only stifled feed, prevents from lacking material or supersaturation charging worn roll skin.
3, action roller pressure regulates.
4, single motor connects TPB planet-gear speed reducer of new generation, is connected and fixed roller end axle with swelling dish, and the one-sided torque support arm of reductor bears torsion, and moment of torsion to be passed in movable roll by one group of floating gear and keeps synchronous in opposite directions by stationary roll.This load mode escapable cost 25%, reduces by the floor space of 40%.
5, key points for operation:
(1) feeding conveying system must arrange tramp iron separator, guarantees without iron block in charging, for ensureing not enter iron, also should arrange metallic element detector.Can find when tramp iron separator loses efficacy and stop conveyer, removing metal piece.
(2) the work of efficient stable, must ensure that feeding continuously and have certain material pressure.
(3) feed size≤0.025D D-roller footpath aniseed is more impairs smoothness of operation and weight roller shelling damage.
(4) No Load Start, feed well of unstowing before parking.
(5) after shutting down, hydraulic system release should be made, every eight hours grease ups after a stoppage, and check the lubricating status of gear-bearing, and hydraulic electric appliance system should carry out installation and debugging Inspection and maintenance according to industry standard specification.
