Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, synchronous flexible compression roller system of the present invention, comprise hydraulic power system, hydraulic actuator, grinding roller 1, pressure arm 2, connect base 3 and ground connecting base 4, described hydraulic power system is connected with hydraulic actuator, described hydraulic actuator is oil hydraulic cylinder 5, described oil hydraulic cylinder 5 one end is connected with floor base, the other end is connected with pressure arm 2, described pressure arm 2 is fixedly connected with grinding roller 1, described pressure arm 2 away from oil hydraulic cylinder 5 one end be connected base 3 and connect, described oil hydraulic cylinder 5 is two, and is arranged symmetrically.Also comprise rigid connecting rod 6, the two ends of described rigid connecting rod 6 are connected with pressure arm 2 respectively.Described pressure arm 2 is connected by U-bolt 7 with grinding roller 1.Basis is fixed on by connecting base 3 in hydraulic jack one end, and one end is connected on synchronous pressure arm 2 in addition.Pressure arm 2 is fixed on tumbling mill base by connecting bearing, then with U bolt, grinding roller 1 system is connected with synchronous pressure arm 2 fast transport arriving power.Between two ends pressure arm 2, be connected with rigid connecting rod 6, make whole pressure arm 2 mechanism have rigid water hammer function.
Described hydraulic power system comprises fuel tank 8, oil pump 9 and selector valve 10, the import of described oil pump 9 is communicated with fuel tank 8, described pump discharge is communicated with selector valve 10, described selector valve 10 is communicated with oil hydraulic cylinder 5, and two oil hydraulic cylinders 5 are connected in parallel in the oil hydraulic circuit of hydraulic power system and oil hydraulic cylinder 5 composition.During concrete enforcement, hydraulic oil unit is placed in outside tumbling mill, oil hydraulic circuit comprises hydraulic power system, hydraulic control component and two identical hydraulic jacks 5, when the normal abrasive material of grinding machine, cylinder rod chamber enters pressure oil, rodless cavity connects petrol station, and the pulling force that piston rod produces makes grinding roller 1 be pressed onto tightly on material.Because two oil hydraulic cylinders 5 are connected in parallel, therefore the lifting of roller is controlled by same selector valve 10, has asynchrony phenomenon to exist when there will not be grinding roller 1 to be elevated.
Throttle valve 11 is provided with between oil pump 9 and selector valve 10.Throttle valve 11 can adjust the rising or falling speed of oil hydraulic cylinder 5 in real time according to process requirements, thus controls the rising or falling speed of grinding roller 1.
Bidirectional hydraulic lock 12 is provided with between oil pump 9 and selector valve 10.The pressure of bidirectional hydraulic lock 12 for making grinding roller 1 keep stable in grinding machine working procedure.
Oil pump 9 outlet port is provided with relief valve 13.The relief valve 13 in oil pump 9 outlet port is used for restriction system pressure, ensures security of system.
Oil pump 9 pump inlet place is provided with filter 14.Filter 14 is used for the impurity in filtered fluid force feed, and the hydraulic element in guarantee system are without prejudice.
Electromagnetic relief valve 15 is also provided with between described selector valve 10 and oil hydraulic cylinder 5.Material enters cylindrical shell by charging port, due to cylindrical shell High Rotation Speed, material is distributed in barrel wall surface due to centrifugal action, by the adjustment of stock guider, material moves to discharging port from charging port successively, need pressing roll system constantly to provide pressure to grind in the process, reach the final quality needed to make material.Due in grinding process, abrasive particle size is uneven, easily causes grinding roller pressure surge, adopts electromagnetic relief valve can make the pressure stability of grinding roller in milling process, thus improves grinding effect.
