Degasser is a wheelbarrow type degassing equipment equipped with imported hydraulic lift (or mechanical lifting system) with online measurement of liquid aluminum temperature rotating rotor degassing equipment, degassing medium using 99.99 percent of argon or nitrogen, its principle is: After the degasser is installed with a graphite rotor placed in liquid aluminum, through the controlled rotation of the graphite shaft and rotor, the measured inert gas is pressed into liquid aluminum and broken up into tiny bubbles, so that the gas partial pressure of bubbles evenly dispersed in the molten metal is zero. Because the hydrogen partial pressure is high, so in liquid aluminum from hydrogen bubbles in the diffusion of liquid aluminum, at the same time the non-metallic inclusions in the aluminum liquid is adsorbed on the bubble surface, useless hydrogen and nonmetallic inclusions inert gas bubbles rise to the fluid surface adhesion, processed, graphite rod rises, for skimming achieved the goal that in addition to hydrogen and oxide inclusions. The degassing arm is equipped with an online liquid aluminum temperature measuring device, which can understand the change of liquid aluminum temperature when degassing, so as to facilitate the operator to understand whether the liquid aluminum meets the requirements of casting temperature. The degasser can be moved flexibly and can be conveniently placed anywhere in the workshop.

Next, let's introduce the types of degasser

First, ultrasonic degasser

It is said that the operation is simple and the degassing effect is good. Used for degassing metal melt, especially for effective removal of hydrogen in aluminum melt. It is an eco-friendly product, which will not emit any harmful substances to the environment during use, and it is also a product with a short payback period.

Two. Water quality degasser

The main cause of fish bubble disease is too much oxygen and nitrogen in the water. What's dangerous to the fish in this case is an excess of individual nitrogen molecules in the water. Water cannot be supersaturated more than 250 to 300 percent, which is rare in nature and lasts for a short time. Through experiments and literature, it has been proved that the percentage of influence of nitrogen saturation on fish growth is: carp should not exceed 115 percent, salmon should not exceed 110 percent to 150 percent. Artificial hatching of fish eggs was carried out in beihai.

Three. Online degasser for aluminum melt

The physical and chemical principle of on-line degassing of liquid aluminum is introduced, and the research status and shortcomings of on-line degassing of liquid aluminum at home and abroad are analyzed. It is found that there are bubbles and short flows in the dynamic two-phase flow. And put forward effective solutions. At the same time invented a number of patent technology, play to the advantages of cooperation, the development of degasser in energy conservation and emission reduction technology and equipment.
