The bottom of staving is placed on the position between four sliding blocks.After a upper staving completes the operation of clear bucket, if next
The size of staving is not changed, and need to only be placed into next staving on the position between four sliding blocks can carry out clearly at once
Bucket operation, eliminates the step of carrying out repositioning centering to the staving after replacement.
Using the above structure, beneficial effects of the present invention:The present invention uses single-screw (single screw) pump as the work pump housing, due to single spiral shell
The flow trim of bar pump, pressure pulse is small, noise is low, high-efficient, the service life is long, reliable operation, and single-screw (single screw) pump is to medium
Viscosity is insensitive, therefore the work pump housing for being highly suitable as clear barrel uses.The present invention due to setting there are two lifting device,
Therefore staving pressing plate can smoothly be gone up and down, and avoid the phenomenon that staving pressing plate is tilted to side;It is fixed that the present invention is additionally provided with barrel bottom
Position mechanism, since the bottom of staving that bucket bottom positioning mechanism can operate last time carry out memory positioning, when needing replacing staving
And when the specification of staving does not change, the bottom of the staving after replacement directly can be placed on bucket bottom positioning mechanism
On, the step of repositioning centering is carried out to staving after replacing staving is eliminated, production efficiency is improved.
It is further used as preferred embodiment, since the feed inlet of single-screw (single screw) pump of the invention is located at the end of stator,
Discharge port is located between screw rod rotating device and transmission device, therefore the high-viscosity material of high pressure passes through transmission device in order to prevent
Power output device is entered, high-pressure-resistant sealed room 7 is equipped between the transmission device and screw rod rotating device.High-pressure-resistant sealed
Room is sealed using fixed double combination, i.e. transmission device one end for being sealedly connected on the high-pressure-resistant sealed room, screw rod rotation
Device is sealedly connected on the other end of the high-pressure-resistant sealed room, and the high-pressure-resistant sealed room is as buffer area.
After the staving pressing plate is contacted with staving, since the outer diameter of the annulus scraper plate on staving pressing plate is slightly larger than the staving
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 solenoid directional control valve on the corresponding position of metal inductive switch
It is electrically connected.The work distance of reaction of metal inductive switch is set first, when the gas bar of Pneumatic power elevator apparatus drops to dead point,
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.Due to
Metal inductive switch and the solenoid directional control valve are electrically connected, when the gas bar of Pneumatic power elevator apparatus drops to dead point, metal sense
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 movement the compressed gas pipeline also inject compressed gas together, the compressed gas is by described unidirectional
The inside of valve inflow staving.
Referring to Fig. 2 and Fig. 3, before use, being first turned on electromagnetic switch threshold switch, compressed gas injection is pneumatic to rise the present invention
Falling unit, the gas bar of Pneumatic power elevator apparatus drive lifter plate and single-screw (single screw) pump to rise to highest point, adjust four sliding blocks away from
From then filling high viscous so that the distance between two sliding blocks on the same locating slot are consistent with the basal diameter of staving
Degree material staving (opening) be placed on barrel bottom positioning mechanism so that the opening of staving be located at the annulus scraper plate just under
Side, opens the reversing switch of solenoid directional control valve later, and the gas bar of Pneumatic power elevator apparatus drives lifter plate and single-screw (single screw) pump decline.
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 exhaust
The external world is discharged at 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 are started 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 to be determined
In son, high-viscosity material in stator is constantly up pushed by the helical rotation of rotor, and high-viscosity material is from discharge room later
Place's discharge.Finally, the intracorporal high-viscosity material of bucket is drained when the gas bar of Pneumatic power elevator apparatus drops to dead point, it is golden at this time
Belong to inductive switch and issues signal instruction to solenoid directional control valve, so that solenoid directional control valve starts to commutate, Pneumatic power elevator apparatus
Gas bar drives compressed gas pipeline while lifter plate and single-screw (single screw) pump rising also to inject compressed gas, the pressure together
Contracting gas flows into the inside of the staving by the check valve, and staving pressing plate is successfully up moved, same with this
When, 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 present invention enters standby shape
State.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 the bucket after replacement
Body carries out repositioning centering, can start new clear bucket operation.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
