Inner diameter, therefore there are sealing spaces between staving and staving pressing plate, if the air in sealing space is not discharged, staving
Pressing plate can not continue to move down.Therefore the staving pressing plate is equipped with exhaust valve 64 and check valve 65, the check valve connection
There is compressed gas pipeline, the on-off of compressed gas pipeline is controlled by the solenoid directional control valve, the exhaust valve and unidirectional
Valve is each provided on the upper annulus platen.The exhaust valve is manual exhaust valve, when the inner wall of staving pressing plate and staving contacts,
Exhaust valve is opened manually, and the air between staving pressing plate and staving is discharged to the external world from exhaust valve；The check valve folk prescription
To the channel for leading to the outside of staving from the inside of staving is enclosed, the check valve allows external note of the compressed gas from staving
Enter to the inside of the staving.
In order to realize automated production, the upper surface of the shell of the lifting device is equipped with metal inductive switch 8, the liter
It drops plate and is equipped with metal baffle 81, the metal inductive switch and the electromagnetic switch on the corresponding position of metal inductive switch
Valve is electrically connected.The work distance of reaction of metal inductive switch is set first, drops to dead point in the gas bar of Pneumatic power elevator apparatus
When, i.e., in metal inductive switch at a distance from metal baffle most in short-term, be at this time the work distance of reaction of metal inductive switch.By
It is electrically connected in metal inductive switch and the solenoid directional control valve, when the gas bar of Pneumatic power elevator apparatus drops to dead point, metal
Inductive switch issues signal instruction to solenoid directional control valve, so that solenoid directional control valve starts to commutate, Pneumatic power elevator apparatus at this time
Gas bar while up move the compressed gas pipeline also inject compressed gas together, the compressed gas passes through the list
The inside of staving is flowed into valve.
Referring to Fig. 2 and Fig. 3, for the utility model before use, being first turned on electromagnetic switch threshold switch, compressed gas injects gas
The gas bar of dynamic lifting device, Pneumatic power elevator apparatus drives lifter plate and single-screw (single screw) pump to rise to highest point, adjusts four sliding blocks
Distance then will be filled so that the distance between two sliding blocks on the same locating slot are consistent with the basal diameter of staving
The staving (opening) of high-viscosity material is placed on barrel bottom positioning mechanism, so that the opening of staving is being located at the annulus scraper plate just
Lower section, opens the reversing switch of solenoid directional control valve later, and the gas bar of Pneumatic power elevator apparatus drives under lifter plate and single-screw (single screw) pump
Drop.When the inner wall of staving pressing plate and staving contacts, exhaust valve is opened manually, by the air between staving pressing plate and staving from row
The external world is discharged at air valve.Then when staving pressing plate touches high-viscosity material, exhaust valve is turned off manually, starts single-screw (single screw) pump
Motor switch, single-screw (single screw) pump starts to work, and the intracorporal high-viscosity material of bucket is drawn by single-screw (single screw) pump from the suction chamber of lower end
In stator, high-viscosity material in stator is constantly up pushed by the helical rotation of rotor, and high-viscosity material is from discharge later
It is discharged at room.Finally, the intracorporal high-viscosity material of bucket is drained, at this time when the gas bar of Pneumatic power elevator apparatus drops to dead point
Metal inductive switch issues signal instruction to solenoid directional control valve, so that solenoid directional control valve starts to commutate, Pneumatic power elevator apparatus
Gas bar drive lifter plate and single-screw (single screw) pump while rising the compressed gas pipeline also inject compressed gas together, it is described
Compressed gas flows into the inside of the staving by the check valve, staving pressing plate is successfully up moved, with this
Meanwhile the motor switch of single-screw (single screw) pump is closed, when the gas bar of Pneumatic power elevator apparatus rises to highest point, the utility model enters
Standby mode.When carrying out the operation of clear bucket next time, empty barrel is replaced with to the new staving for filling high-viscosity material, is not needed to replacement
Staving afterwards carries out repositioning centering, can start new clear bucket operation.
The better embodiment of the utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make various equivalent changes without departing from the spirit of the present invention
Type or replacement, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
