[0002] The production process of paint requires a lot of stirring and mixing reactions. During the stirring process, a large number of bubbles will inevitably be mixed into the paint. Due to the high viscosity of the paint, the bubbles in it cannot be discharged naturally. The bubbles in the paint will cause the oxidation of the reactive substances in the paint, affecting the performance of the paint and being detrimental to the long-term storage of the paint. Therefore, after the paint is prepared, the paint is usually defoamed to remove the bubbles in the paint. The more common way to defoam paint is vacuum defoaming. However, the defoaming efficiency of the existing vacuum defoaming device is low and the defoaming is not sufficient. Utility Model Content

The first disc plate 13 and the second disc plate 14 are respectively provided with a filter hole 17. The first disc plate 13 is located above the second disc plate 14, and a hollow bracket 15 is provided between the first disc plate 13 and the second disc plate 14. A motor 16 for driving the baffle rotating shaft is provided in the middle position of the hollow bracket 15. A plurality of inclined plates 10 are staggered below the second disc plate 14. The other end of the inclined plate 10 except the bottom layer is a free end and extends obliquely downward in the defoaming tank 12. A discharge pipe 11 is provided at the bottom of the discharge area 3 to be connected to the discharge port.

[0016] Furthermore, the outlet of the feed pipe 6 faces the first disc plate 13 .

[0017] Furthermore, the shaft baffle 7 is connected to the motor via a shaft 18 .

[0018] Furthermore, the filter material holes 17 of the first disc plate 13 and the filter material holes 17 of the second disc plate 14 are provided with valve switches, wherein the filter material holes 17 of the first disc plate 13 and the filter material holes 17 of the second disc plate 14 are staggered in vertical arrangement.

[0019] Furthermore, the distance from the position of the filter hole 17 to the center of the disc is the radius length.

[0020] Furthermore, the discharge port is connected to a discharge pipe 11 , one end of the bottom inclined plate is fixedly connected to the inner wall of the defoaming tank 12 , and the discharge pipe 11 is connected to a paint storage tank.

[0021] When in use, the paint is injected from the feed pipe above the defoaming tank, and the paint to be defoamed is introduced into the feed area through the feed pipe. Each disc plate can be provided with multiple filter holes, and the ratio of the distance from the position of the filter hole to the center of the disc plate to the radius of the disc plate must meet the following requirements: The paint flows to the first and second disc plates. The two disc plates cooperate with a mechanical vibrator to form a large-area thin layer of flow during debubbling, so that the paint can be evenly debubbled everywhere. The large-area thin layer accelerates the rate of bubble detachment, thereby improving the debubbling effect. The debubbling process can be processed by setting a timer. When the timer reaches a preset time, the rotating shaft baffle can be started to automatically clean the paint remaining on the disc plate, allowing it to flow out through the filter holes of the disc plate. When the paint flows to the inclined plate arranged on the inner wall of the debubbling tank from top to bottom, the paint forms a serpentine curved flow after entering the inclined plate, which prolongs the debubbling time of the paint and allows the bubbles in the paint to be more fully detached. The debubbling efficiency is high and the debubbling is very sufficient. The detached bubbles are discharged from the exhaust port, and the degassed paint enters the discharge area and is discharged from the discharge port.

[0022] The beneficial effects of the vacuum vibration defoaming device of the utility model are as follows: filling and defoaming are carried out simultaneously, and the two disc plates cooperate with the mechanical vibrator to make the paint always flat during defoaming to form a large-area thin layer of flow, so that the paint everywhere can be defoamed evenly, and the large-area thin layer accelerates the rate of bubble detachment, thereby improving the defoaming effect. The inclined plate is arranged on the inner wall of the defoaming tank at an angle from top to bottom. After the paint enters the inclined plate, it forms a serpentine curved flow, which prolongs the defoaming time of the paint, so that the bubbles in the paint can be more fully detached, and the defoaming efficiency is high and the defoaming is sufficient.
