[0027] During operation, the grease and defoaming agent that need to be degassed can be injected along the feed pipe 7, and the motor 3 can be used to drive the stirring rod 5 to rotate. The rotation of the stirring rod 5 can drive the stirring plate 6 to stir the tank, so that the two liquids are mixed and the bubbles inside the grease are eliminated. When the bubbles are eliminated, the operating handle 15 is turned to drive the butterfly valve 9 to rotate, and the defoamed grease inside the degassing box 2 is discharged from the degassing box 2, and the stirred grease will flip up and down. The No. 1 limit block 19 abuts against the rotating plate 18 to prevent the liquid from flowing back, and the injection rotating plate 18 will rotate along the rotating shaft 16 to inject the liquid into the degassing box 2, which solves the problem of backflow through a single inlet and outlet causing pollution to the unmixed liquid.

[0037] During operation, the transmission belt 10 can drive the reciprocating screw 11 to rotate, and the rotation of the reciprocating screw 11 will drive the lower pressure plate 12 to move up and down. The No. 3 limit block 14 ensures that the lower pressure plate 12 will not fall off, and the grease will interact up and down along the air hole 13. The mixing effect achieved in this way better solves the problem of poor mixing effect in the past and improves the mixing effect of grease and defoaming agent.

[0038] The working principle is that the grease and defoaming agent that need to be degassed can be injected along the feed pipe 7, and the motor 3 drives the stirring rod 5 to rotate. The rotation of the stirring rod 5 drives the stirring plate 6 to stir the tank, so that the two liquids are mixed and the bubbles inside the grease are eliminated. When the bubbles are eliminated, the operating handle 15 is turned to drive the butterfly valve 9 to rotate, and the defoamed grease inside the degassing box 2 is discharged from the inside of the degassing box 2, and the stirred grease will flip up and down. The No. 1 limit block 19 abuts against the rotating plate 18 to prevent the liquid from flowing back, and the injection-type rotating plate 18 will rotate along the rotating shaft 16 to inject the liquid into the degassing box 2, which solves the problem of contamination of the unmixed liquid caused by backflow through a single inlet and outlet in the past. When the grease needs to be injected along the feed pipe 7, the rotating plate 18 will rotate along the rotating shaft 16, and when the rotating plate 18 rotates, it will abut against the side of the No. 2 limit block 20 to avoid the problem of excessive rotation of the rotating plate 18, thereby realizing one-way injection.

The reciprocating screw 11 rotates to drive the lower pressure plate 12 to move up and down, and the reciprocating screw 11 rotates and runs more stably at the top of the degassing box 2. The No. 3 limit block 14 can prevent the lower pressure plate 12 from reaching the maximum position when moving up and down to the effect of slipping off the lower pressure plate 12 from the outside of the air vent 13. The reciprocating screw 11 can be driven by the transmission belt 10 to rotate, and the rotation of the reciprocating screw 11 will drive the lower pressure plate 12 to move up and down, and the No. 3 limit block 14 ensures that the lower pressure plate 12 will not fall off, and the grease will interact up and down along the air vents 13. The mixing effect is better solved in this way, and the problem of poor mixing effect in the past is improved.
