Embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of energy-conservation crust breaking cylinder for aluminum electrolysis industry is (referring to Fig. 1-Fig. 5), it comprises large cylinder barrel 7, be provided with piston rod 11 in the large cylinder barrel 7, be provided with large piston 10 between large cylinder barrel 7 and the piston rod 11, one end of large cylinder barrel 7 is provided with protecgulum 12, piston rod 11 passes protecgulum 12 and connects fork-shaped extension bar 13, connect little cylinder barrel 6 by setting sleeve 15 in the large cylinder barrel 7, be provided with small piston 4 in the little cylinder barrel 6, guide piston 3, be provided with two way sealed 18 and J type sealing 16 between little cylinder barrel 6 and the small piston 4, large cylinder barrel 7 the other ends are provided with reversing valve complement 2, reversing valve complement 2 order of connection valves 1, sequence valve 1 is by the first Pneumatic valve 1-1, the second Pneumatic valve 1-2, gas circuit 22 consists of, and reversing valve complement 2 comprises the first selector valve 2-1, the second selector valve 2-2, on it with control mouthfuls 20, working hole 21 also is fitted with braking lock 23.Control mouthful 20 connection 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.Cavity between reversing valve complement 2, little cylinder barrel 6, large cylinder barrel 7 and the setting sleeve 15 has formed 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, the protecgulum 12 is rod chamber 17.Cavity between small piston 4, little cylinder barrel 6, the reversing valve complement 2 has formed rodless cavity 19.The second selector valve 2-2 communicates with rod chamber 17 by breathing pipe 8, protecgulum 12.Small piston 4, hook 9, large piston 10, spring sheet 14, setting sleeve 15 have formed hook system, realize connection and the disengaging of large piston and small piston.Hook 9, spring sheet 14 are fixed on above the large piston 10, and setting sleeve 15 is fixed on the 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 into the pressurized air that pressure is 0.6 ~ 1MPa at working hole 21.As can be seen from Figure 6, this moment, rod chamber 17 was full of pressurized air, and large piston 10, hook 9 rest on as shown in Figure 6 position; Cylinder tail end braking lock 23 is in opening state; The spool of the second selector valve 2-2 is positioned at initial position, the cylinder attonity.
2, pass into the pressurized air that pressure is 0.6-0.1MPa at control mouth 20, the spool action of the second selector valve 2-2, the spool commutation, the second Pneumatic valve 2-2 is in closed condition simultaneously.The pressurized air that pass into by working hole 21 this moment 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 Figure 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, do not seal this moment, and the pressurized air in the rodless cavity 19 enters into gas storage chamber 5.Because large piston 10 left side rod chambers 17 have pressurized air, air pressure is all identical with pressure in working hole 21, rodless cavity 19, the gas storage chamber 5, and large piston both sides compression area is identical, therefore piston rod 11, small piston 4, guide piston 3 continue to left movement under the Action of Gravity Field of the hammer body that self and front end connect.
4, when moving to position shown in Figure 8, large piston 10, hook 9 leave setting sleeve 15, and hook 9 is in state shown in Figure 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 ends touch load, because piston 10 pressure at both sides are identical greatly, this moment 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, the rod chamber 17 raises simultaneously.When setting value that the pressure in the gas storage chamber 5 raises, the action of the first Pneumatic valve 1-1 spool, the first selector valve 2-1 control gas circuit is connected, the action of the first selector valve 2-1 spool, rod chamber 17 is in the pressure release state.The power that large piston 10, small piston 4, piston rod 11 produce left promotes load, finishes the action of requirement, stretches out state fully until move to piston rod 11, as shown in Figure 9.
Piston rod retraction process:
1, cylinder removes the pressurized air of control mouthful K under state shown in Figure 9, and the second selector valve 2-2 spool resets under spring action, and rodless cavity 19, gas storage chamber 5 are in exhaust condition.The second Pneumatic valve 1-2 commutation, the control gas circuit of the first selector valve 2-1 is in the mistake gaseity, the commutation of the first selector valve 2-1 spool, working hole 20 communicates with rod chamber 17, and large piston 10, small piston 4, piston rod 11 move right.
2, move to state shown in Figure 8 when large piston 10, small piston 4, piston rod 11, hook 9, hook 9 beginnings contact with setting sleeve 15, and along with said modules further moves right, hook 9 breaks away from small piston 4 gradually, thereby large piston 10 and small piston 4 are broken away from, 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 directions.In the 1st, 2 step, the air pressure of gas storage chamber drops to specified value from peak, and this moment, small piston 4 left side pressure were the pressure of gas storage chamber 5, and the right side is barometric pressure, and small piston 4, piston rod 11 are subjected to power to the right, move right, until move to state shown in Figure 9.
