Description

Technical Field

[0001] The utility model relates to the technical field of vacuum degassing, in particular to a vacuum degassing device. Background Art

[0002] Circulating water is required in heating and cooling systems. When there is gas in the circulating water, it is easy to cause air blockage in the equipment, resulting in unbalanced system resistance. When the system circulation is not smooth, it is easy to generate noise and cavitation, which has many adverse effects on the operation of the equipment. Therefore, the circulating water needs to be degassed during the water supply process to prevent gas from flowing into the equipment with the circulating water. This solution specifically involves a vacuum degassing device. The existing vacuum degassing device adopts negative pressure degassing, but the inner wall of the water supply pipe is easily corroded after long-term use. The debris detached from the inner wall forms suspended matter and flows into the vacuum degassing device with the circulating water, causing pipeline blockage. At the same time, during the negative pressure degassing process, the tiny bubbles in the circulating water will still retain air, and the bubbles cannot be punctured. The retained air cannot be removed, which will affect the degassing effect. Utility Model Content

[0003] The main purpose of the utility model is to provide a vacuum degassing device, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A vacuum degassing device comprises a base frame, a vacuum tank is fixedly mounted on one side of the top of the base frame, an ultrasonic generator is arranged at the top of the base frame and at the front end of the vacuum tank, an ultrasonic vibration rod connected to the ultrasonic generator is installed inside the vacuum tank, and the bottom end of the ultrasonic vibration rod is fixedly connected to the tank body of the vacuum tank, and a vacuum degassing pump is fixedly mounted on the top of the base frame and at one side of the ultrasonic generator.

[0006] As a further solution of the utility model, a water pipe is fixedly installed between the water outlet of the vacuum tank and the water inlet of the vacuum degassing pump, and a through valve is fixedly installed at the water outlet of the vacuum degassing pump.

[0007] As a further solution of the utility model, an electric control box is fixedly installed on the top of the base frame and on one side of the vacuum tank.

[0008] As a further solution of the utility model, an exhaust valve is fixedly installed through the top of the vacuum tank, and a pressure gauge is fixedly installed through the top of the vacuum tank and located on one side of the exhaust valve.

[0009] As a further solution of the utility model, a solenoid valve is fixedly installed at the water inlet of the vacuum tank, and an ultrafiltration membrane filter element is installed at the front end of the solenoid valve.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model is provided with a vacuum tank, a vacuum degassing pump, an ultrasonic generator, an ultrasonic vibration rod and an ultrafiltration membrane filter element. When circulating water passes through the ultrafiltration membrane filter element, it is filtered by the ultrafiltration membrane filter element to remove suspended matter in the water, and prevents the suspended matter from entering the vacuum degassing device with the circulating water to cause blockage. When water enters the interior of the vacuum tank, the vacuum degassing pump and the ultrasonic generator are started, and negative pressure is formed inside the vacuum tank. At the same time, the ultrasonic vibration rod vibrates, and the formed ultrasonic wave shatters the bubbles in the circulating water. Under the negative pressure state, the free and dissolved water in the circulating water is released and then discharged through the exhaust valve, so that the degassing process is completed, and it is prevented that the bubbles in the circulating water wrap the gas and affect the degassing effect.

The pressure inside the vacuum tank 2 is monitored by the pressure gauge 9 to prevent the negative pressure from exceeding the load of the vacuum tank 2. At the same time, the exhaust valve 8 is used to facilitate the discharge of gas inside the vacuum tank 2.

[0021] A solenoid valve 10 is fixedly installed at the water inlet of the vacuum tank 2 , and an ultrafiltration membrane filter element 11 is installed at the front end of the solenoid valve 10 .
