[0019] An online continuous vacuum degassing and stirring process method, based on the above-mentioned online continuous vacuum degassing and stirring machine, comprises the following steps: Step 1: Automatic injection, using the first electric telescopic shaft to drive the first one-way valve pipeline to be inserted into the mixing tank body, using the injection pipe to automatically transport the slurry in the raw material tank to the first one-way valve pipeline, and automatically injecting the slurry into the mixing tank body through the first one-way valve pipeline; Step 2: Degassing and stirring, using a driving motor to drive the rotation of the driving wheel, and through the transmission belt and the driven wheel to drive the central axis and the horizontal support to rotate, thereby driving the rotation of the stirring tank body after the filling is completed; at the same time, using a vacuum device to evacuate the inside of the sealed tank body, so that the sealed tank body and the stirring tank body become a vacuum state, thereby removing bubbles in the slurry; Step three: automatic material extraction. After the mixing tank body stops rotating, the second electric telescopic shaft is used to drive the second one-way valve pipe to be inserted into the mixing tank body. The finished product slurry in the mixing tank body is sucked by the extraction pipe and the second one-way valve pipe, thereby automatically sucking the finished product slurry into the finished product tank.

[0020] By adopting the above technical solution, automatically injecting slurry into the mixing tank body and automatically extracting the finished slurry in the mixing tank body helps to improve the loading and unloading efficiency of the vacuum degassing mixer, thereby helping to improve the production efficiency of the vacuum degassing mixer.

When the degassing and stirring of the slurry is completed, the driving motor 54 stops running, and when the positioning disk 13 rotates to a specific position, the piston rod of the positioning cylinder 15 extends, driving the positioning wedge 16 to insert into a specific positioning notch 14, which helps to stop the positioning disk 13 and the central shaft 52 from rotating, so that the stirring tank body 4 stops at a specific position, which is convenient for sucking the slurry in the stirring tank body 4.

[0051] Step 3: Automatic material extraction. When the mixing tank body 4 stops at a specific position, the driving motor 54 stops running. When the positioning disk 13 rotates to a specific position, the piston rod of the positioning cylinder 15 extends, driving the positioning wedge 16 to insert into the specific positioning notch 14, thereby helping to stop the positioning disk 13 and the central axis 52 from rotating, so that the mixing tank body 4 stops at a specific position.

After the extraction is completed, the second electric telescopic shaft 92 drives the second one-way valve pipeline 93 to be extracted from the mixing tank body 4, thereby helping to complete the automatic material extraction of a single mixing tank body 4, thereby helping to improve the material extraction efficiency of the vacuum deaerator, and helping to improve the production efficiency of the vacuum deaerator.

[0052] When the second one-way valve pipe 93 is pulled out of the mixing tank body 4, the piston rod of the telescopic cylinder 11 extends, driving the collecting box 12 to move to the bottom of the second one-way valve pipe 93, thereby facilitating the use of the collecting box 12 to collect the slurry dripping from the second one-way valve pipe 93, and helping to avoid the slurry from dripping outside the mixing tank body 4 as much as possible.

[0053] The driving motor 54 is running, driving the driving wheel 55 to rotate through the output shaft, and then driving the central shaft 52 to rotate through the transmission belt 57 and the driven wheel 56, so that the cross support 53 and the mixing tank body 4 rotate. When the central shaft 52 rotates, the positioning sensor 18 monitors the position of the sensing element 17 in real time. When the central shaft 52 rotates to a specific angle, the piston rod of the positioning cylinder 15 extends, driving the positioning wedge 16 to insert into the specific positioning notch 14, which helps to stop the positioning plate 13 and the central shaft 52 from rotating, so that the mixing tank body 4 stops at a specific position, which is convenient for automatic material extraction of several mixing tank bodies 4 in sequence.
