[0020] A constant-pressure water replenishment vacuum degassing device comprises a water tank 1, on which a water pipe 2 and an air pipe 3 are respectively arranged, on which a water pump 4 is arranged, on which an air pump 5 is arranged, on which a mounting box 6 is fixedly installed on the top of the water tank 1, and the mounting box 6 is communicated with the water tank 1, and a pressure sensor 7 is fixedly installed on the top of the mounting box 6, and a movable plate 8 is slidably arranged on the mounting box 6, and springs 1 9 and springs 2 10 are fixedly installed on both sides of the movable plate 8, respectively, and the spring 1 9 is pressed between the mounting box 6 and the movable plate 8, and the spring 2 10 is pressed between the pressure sensor 7 and the movable plate 8, and a floating plate 11 is fixedly installed on one end of the movable plate 8 away from the mounting box 6, and stirring rods that are evenly distributed and symmetrical are arranged in the water tank 1. 12, the water tank 1 is provided with a driving member 13 for driving the stirring rod 12 to stir the water, the driving member 13 includes a motor 131 fixedly mounted on the water tank 1, a gear 132 and a gear 132 rotatably mounted on the water tank 1, and a rotating rod 134 rotatably mounted in the water tank 1, the end of the output shaft of the motor 131 is fixedly mounted on the middle part of the gear 1 132, the gear 1 132 is meshingly connected with the gear 2 133 for transmission, the top of the rotating rod 134 is fixedly mounted on the middle part of the gear 2 133, the stirring rods 12 are respectively fixedly mounted on the rotating rod 134, and the stirring rods 12 are fixedly mounted with stirring blades 14 evenly distributed, and a heating portion 15 is sleeved on the bottom of the water tank 1, and a heating resistance wire is arranged in the heating portion 15.

[0021] The water tank 1 is provided with a controller, which is respectively connected with the water pump 4, the vacuum pump 5, the pressure sensor 7, the motor 131 and the heating resistance wire.

[0022] Working principle:

[0023] When the water level in the water tank 1 changes, the floating plate 11 will float up and down accordingly. Since the floating plate 11 is fixedly connected to the movable plate 8, the movable plate 8 will also slide up and down in the installation box 6. When the water level rises, the floating plate 11 drives the movable plate 8 to move upward, compressing the spring 19 and stretching the spring 2 10 at the same time. Conversely, when the water level drops, the floating plate 11 drives the movable plate 8 to move downward, the spring 19 returns to its original state and the spring 2 10 is compressed. In this process, the pressure sensor 7 will monitor the pressure changes caused by the spring 19 on it in real time, and transmit these signals to the controller. The controller determines the current water level according to the received pressure signal, and controls the working state of the water pump 4 accordingly. By starting the water pump 4, the water tank 1 can be accurately replenished with water through the water pipe 2. By combining the mechanical and electronic control systems, the water replenishment efficiency of the water tank 1 can be significantly improved. The vacuum pump 5 on the air pipe 3 is started to perform a vacuum operation vertically.

[0024] When the motor 131 is started, its output shaft drives the gear 132 to rotate. Since the gear 132 is meshed and connected with the gear 2 133, the rotation of the gear 132 will drive the gear 2 133 to rotate synchronously. The middle part of the gear 2 133 is fixedly installed with the top of the rotating rod 134, so the rotating rod 134 will also rotate with the rotation of the gear 2 133, and the stirring rod 12 and the stirring blade 14 fixedly installed on the rotating rod 134 will rotate accordingly to fully stir the water. At the same time, the heating resistance wire in the heating part 15 is energized and heated under the control of the controller to heat the water at the bottom of the water tank 1, which can not only make the gas in the water easier to precipitate through stirring, but also further reduce the solubility of the gas through heating, thereby enhancing the vacuum pump 5 The vacuuming effect, the controller controls the working state of the motor 131 and the heating resistance wire according to the needs of the system to ensure stable and efficient operation of the system;

[0025] The constant-pressure water-replenishing vacuum degassing device can significantly improve the water-replenishing efficiency and vacuuming effect of the water tank 1, ensuring stable and efficient operation of the system. The overall structure of the device is simple and highly practical.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
