Wall flow type vacuum degassing system based on automatic circulating liquid degassing technology

Abstract

The invention discloses a wall flow type vacuum degassing system based on an automatic circulating liquid degassing technology, and relates to the technical field of opto-mechatronics. The system comprises a frame body, a degassing tank, a water pump, a suction fan and a control electric box, the water pump is fixedly installed at one side of the interior of the frame body, and the suction fan isfixedly installed at the other side of the inner wall of the frame body; and the degassing tank is fixed to one side of the upper end face of the frame body, the control electric box is fixedly installed on the other side of the upper end face of the frame body, a connecting air pipe is fixed between the suction fan and the degassing tank, and an upper cover plate is fixedly installed on the upperend face of the degassing tank. According to the vacuum degassing system, vacuum can be quickly formed in the degassing tank, so that an external operator can operate and treat the degassing tank conveniently, the degassing tank can be quickly and effectively fixed, the external operator can operate and process the degassing tank conveniently, meanwhile, the airtightness between the connecting air pipe and the hollow pipe is better, and gas leakage is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of optical-mechanical-electrical integration, in particular to a wall-flow vacuum degassing system based on circulating liquid automatic degassing technology. Background technique [0002] The vacuum degassing of molten steel is carried out in a special vacuum chamber, which is lined with refractory bricks. At the bottom, there are two pipes made of refractory materials that can be inserted into molten steel, namely, molten steel riser and The downcomer, when the driving gas is passed into the upcomer, can promote the molten steel in the ladle to circulate through the vacuum chamber, and the wall flow vacuum degassing is a new technology that can realize the removal of gas from the circulating liquid. The liquid circulating under pressure swirls out along the airtight container to form a water film, while the gas escapes from the liquid in the central vacuum area of ​​the container and rises to the exhaust v...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a wall-flow vacuum degassing system based on circulating liquid automatic degassing technology, which solves the problem that there is no good flow guide mechanism inside, which causes some small gases to adhere to the inside of the barrel wall , resulting in some gas remaining inside the vacuum machine, which is not conducive to the vacuum treatment of the specified liquid
