Embodiment: a kind of energy-conservation crust breaking cylinder for aluminum electrolysis industry (see Fig. 1-Fig. 5), it comprises large cylinder barrel 7, piston rod 11 is provided with in large cylinder barrel 7, large piston 10 is provided with between large cylinder barrel 7 and piston rod 11, one end of large cylinder barrel 7 is provided with protecgulum 12, piston rod 11 connects fork-shaped extension bar 13 through protecgulum 12, little cylinder barrel 6 is connected by setting sleeve 15 in large cylinder barrel 7, small piston 4 is provided with in little cylinder barrel 6, guide piston 3, two way sealed 18 and J type sealing 16 is provided with between little cylinder barrel 6 and small piston 4, large cylinder barrel 7 the other end is provided with reversing valve complement 2, reversing valve complement 2 order of connection valve 1, sequence valve 1 is by the first Pneumatic valve 1-1, second Pneumatic valve 1-2, gas circuit 22 is formed, reversing valve complement 2 comprises the first selector valve 2-1, second selector valve 2-2, with control mouth 20 on it, working hole 21, also be fitted with braking lock 23.Control mouth 20 and be communicated with the first selector valve 2-1, the second Pneumatic valve 1-2.Working hole 21 is communicated with the first selector valve 2-1, the second selector valve 2-2.Reversing valve complement 2, little cylinder barrel 6, large cavity between cylinder barrel 7 and setting sleeve 15 define gas storage chamber 5.Gas storage chamber 5 is communicated with the first Pneumatic valve 1-1 by gas circuit 22.Cavity between large piston 10, large cylinder barrel 7, piston rod 11, protecgulum 12 is rod chamber 17.Cavity between small piston 4, little cylinder barrel 6, reversing valve complement 2 defines rodless cavity 19.Second selector valve 2-2 is communicated with rod chamber 17 by breathing pipe 8, protecgulum 12.Small piston 4, hook 9, large piston 10, spring sheet 14, setting sleeve 15 constitute hook system, realize connection and the disengaging of large piston and small piston.Hook 9, spring sheet 14 are fixed on above large piston 10, and setting sleeve 15 is fixed on little cylinder barrel 6.
Working principle:
Piston rod stretches out process:
1, as shown in Figure 6, cylinder piston rod 11 is in complete retracted mode, passes at working hole 21 pressurized air that pressure is 0.6 ~ 1MPa.As can be seen from Figure 6, now rod chamber 17 is full of pressurized air, and large piston 10, hook 9 rest on position as shown in Figure 6; Cylinder tail end braking lock 23 is in opening state; The spool of the second selector valve 2-2 is positioned at initial position, cylinder attonity.
2, pass into the pressurized air that pressure is 0.6-0.1MPa, the spool action of the second selector valve 2-2 at control mouth 20, spool commutates, and the second Pneumatic valve 2-2 is in closed condition simultaneously.The pressurized air now passed into by working hole 21 enters into the little cylinder barrel rodless cavity 19 of cylinder, promotes small piston 4, guide piston 3 and piston rod 11 to left movement.
3, when piston rod 11, small piston 4 and guide piston 3 run to position shown in Fig. 7, small piston 4 contacts with large piston 10, and two way sealed 18 is separated with little cylinder barrel 6, and J type sealing 16 is one-way sealings, now do not seal, the pressurized air in rodless cavity 19 enters into gas storage chamber 5.Because on the left of large piston 10, rod chamber 17 has pressurized air, air pressure is all identical with the pressure in working hole 21, rodless cavity 19, gas storage chamber 5, and large piston both sides compression area is identical, therefore, under the Action of Gravity Field of hammer body that piston rod 11, small piston 4, guide piston 3 connect in self and front end, continue to left movement.
4, when moving to position shown in Fig. 8, large piston 10, hook 9 leave setting sleeve 15, and hook 9 is in state shown in Fig. 8 under the effect of spring sheet 14, and large piston 10, small piston 4 connect as a whole by hook 9.
5, after piston rod 11 front end touches load, because large piston 10 pressure at both sides is identical, now no-output power, piston rod 11, large piston 10, hook 9, small piston 4, guide piston 3 action movement under load stops, the pressure in rodless cavity 19, gas storage chamber 5, rod chamber 17 raises simultaneously.When the setting value that the pressure in gas storage chamber 5 raises, the first Pneumatic valve 1-1 spool action, the first selector valve 2-1 controls gas circuit and connects, and the first selector valve 2-1 spool action, rod chamber 17 is in pressure release state.Large piston 10, small piston 4, piston rod 11 produce power left, promote load, complete the action of requirement, until move to piston rod 11 to stretch out state completely, as shown in Figure 9.
Piston rod retraction process:
1, cylinder is under state shown in Fig. 9, and remove the pressurized air controlling mouth K, the second selector valve 2-2 spool resets under the action of the spring, and rodless cavity 19, gas storage chamber 5 are in exhaust condition.Second Pneumatic valve 1-2 commutates, and the control gas circuit of the first selector valve 2-1 is in mistake gaseity, and the first selector valve 2-1 spool commutation, working hole 20 communicates with rod chamber 17, and large piston 10, small piston 4, piston rod 11 move right.
2, when large piston 10, small piston 4, piston rod 11, hook 9 move to state shown in Fig. 8, hook 9 starts to contact with setting sleeve 15, and along with said modules further moves right, hook 9 departs from small piston 4 gradually, thus large piston 10 is departed from small piston 4, as shown in Figure 7.
3, when Fig. 7 state, J type Sealing enters into little cylinder barrel 6, plays seal action from gas storage chamber 5 to rodless cavity 19 direction.In the 1st, 2 step, the air pressure of gas storage chamber drops to specified value from peak, and now small piston 4 left pressure is the pressure of gas storage chamber 5, and right side is barometric pressure, and small piston 4, piston rod 11, by power to the right, move right, until move to state shown in Fig. 9.
