Description

Technical Field

[0001] The present invention relates to the technical field of degassing units, and in particular to an exhaust device of a constant-pressure water-supplementing vacuum degassing unit. Background Art

[0002] Constant-pressure water-makeup vacuum degassing units are primarily used to address pressure fluctuations and air blockages in heating, air-conditioning, and other systems, improving system stability and reliability. In heating and air-conditioning systems, the flow and circulation of water is crucial for heat transfer and air conditioning. However, due to system complexity and volatile operating environments, pressure fluctuations and air blockages often occur, leading to unstable system operation and impacting heating and air-conditioning performance. Constant-pressure water-makeup vacuum degassing units effectively address these issues, ensuring system operation and improving heating and air-conditioning performance, while also contributing to energy conservation, emission reduction, and environmental protection.

[0003] When using the existing constant-pressure water-making vacuum degassing unit, it is found that during the degassing process of the degassing tank in the constant-pressure water-making vacuum degassing unit for degassing the gas in the water, the gas in the water cannot be fully squeezed out, so that some dense bubbles containing gas are mixed in the water, resulting in a low degassing effect of the degassing tank on the water. After long-term use, some pipes and parts in the constant-pressure water-making vacuum degassing unit will be corroded, resulting in a reduction in the service life of the constant-pressure water-making vacuum degassing unit. At the same time, since the general constant-pressure water-making vacuum degassing unit is vacuumed by direct pumping when pumping air, it is easy to pump out the water vapor inside the water tank, and some of the pumping devices are easily corroded due to the corrosive effect of water vapor, thereby affecting the overall service life. Summary of the Invention

At the same time, the driving mechanism drives the transmission pipe and the exhaust elbow to rotate, so that the water adsorbed on the blocking brush in the exhaust elbow is thrown out of the exhaust elbow under the action of centrifugal force, and then the blocking brush continues to adsorb the water vapor in the gas during the suction process, thereby effectively realizing the continuous removal of water vapor in the degassing tank during the suction and vacuum, effectively preventing the water vapor from corroding the vacuum pump and the pipeline, and improving the service life of the degassing unit.

[0018] (3) At the same time, when the degassing tank is exhausted after degassing, the exhaust valve on the connecting pipe can be opened, and then the gas degassed in the degassing tank is discharged through the exhaust elbow. At the same time, the blocking bristles in the exhaust elbow block the water vapor in the gas, preventing the loss of water in the degassing unit and causing waste of resources.

[0031] A transmission pipe 5 is rotatably connected to the degassing tank 4 , and an exhaust device is provided on the outer surface of the transmission pipe 5 . The exhaust device is used to vacuum the degassing tank 4 and squeeze out the gas in the water.

[0032] The exhaust device includes a plurality of exhaust elbows 11 fixedly connected to the transmission pipe 5, a plurality of blocking bristles 12 are fixedly connected inside the exhaust elbow 11, the top of the transmission pipe 5 is rotatably connected to a connecting pipe 13 fixedly connected to the degassing tank 4, and the top of the connecting pipe 13 is fixedly connected to a vacuum pump 14 fixedly connected to the mounting plate 1 through a pipeline, and the outer surface of the transmission pipe 5 is transmission-connected to a driving mechanism connected to the degassing tank 4, and the driving mechanism is used to drive the transmission pipe 5 to rotate.

[0035] When it is necessary to suction and vacuum the degassing tank 4, the vacuum pump 14 works at this time, and the vacuum pump 14 suctions and vacuums the transmission pipe 5 through the pipeline and the connecting pipe 13. Then the transmission pipe 5 evacuates the degassing tank 4 through the exhaust elbow 11, and the gas is discharged through the exhaust elbow 11. During the discharge process, the blocking bristles 12 in the exhaust elbow 11 block the water vapor contained in the gas during the exhaust process so that it adheres to the blocking bristles 12, preventing the water vapor contained in the gas from entering the vacuum pump 14 and the pipeline, thereby preventing the vacuum pump 14 and The pipeline is corroded, and at the same time, the driving mechanism drives the transmission pipe 5 to rotate, and the transmission pipe 5 drives the exhaust elbow 11 to rotate. At this time, the water vapor attached to the blocking bristles 12 in the exhaust elbow 11 is thrown out from the blocking bristles 12 under the action of centrifugal force, and then discharged into the degassing tank 4. Then the blocking bristles 12 continue to adsorb the water vapor in the gas during the suction process, thereby effectively realizing the continuous removal of water vapor in the degassing tank 4 during the suction and vacuuming, effectively preventing water vapor from corroding the vacuum pump 14 and the pipeline, and improving the service life of the degassing unit.

The outer surface of the transmission column 22 is fixedly connected to a plurality of first extrusion plates 23 slidably connected to the transmission tube 5. A plurality of second extrusion plates 24 fixedly connected to the transmission tube 5 are arranged below the first extrusion plates 23. A plurality of through grooves 25 are provided on the first extrusion plates 23 and the second extrusion plates 24. The top end of the connecting tube 13 is fixedly connected to an exhaust valve 26. The top end of the transmission column 22 is transmission-connected to a transmission mechanism transmission-connected to the degassing tank 4.

[0041] A spline groove is formed on the first extrusion disc 23 , and a transmission block fixedly connected to the transmission pipe 5 is slidably connected in the spline groove.

[0042] When the degassing tank 4 degasses the gas in the incoming water, the mounting plate 21 is driven to rotate through the transmission pipe 5, and the mounting plate 21 drives the connecting plate 31 to rotate, and then the connecting plate 31 drives the transmission rod 32 to rotate. At this time, the roller 35 on the transmission rod 32 is fitted with the arc-shaped transmission plate 36 on the degassing tank 4, and the arc-shaped transmission plate 36 drives the transmission rod 32 to move toward the center of the mounting plate 21, and the transmission rod 32 drives the first transmission block 33 to move, and the first transmission block 33 drives the second transmission block 34 to move downward, and the second transmission block 34 drives the transmission column 22 to move downward, and the transmission column 22 drives the first extrusion plate 23 to move downward.

[0043] At the same time, when the degassing tank 4 is exhausted after degassing, the exhaust valve 26 on the connecting pipe 13 can be opened, and then the gas degassed in the degassing tank 4 is discharged through the exhaust elbow 11. At the same time, the blocking bristles 12 in the exhaust elbow 11 block the water vapor in the gas to prevent the loss of water in the degassing unit and waste of resources.
