It belongs to chemical production technology, that is, chemical process. The obtained products are called chemicals or chemical products. In the process of chemical preparation, people need to use transfer tanks to store intermediate products or recyclable filtrates. For example, in the nitration process, the nitration filtrate can be reused once, and the nitration filtrate needs to be temporarily stored in a transfer tank. After being stored in the transfer tank, a large number of bubbles will appear on the surface of the filtrate, affecting its use.

In this patent, defoaming is achieved by rotating the cross arm, but the height adjustment of the cross arm is sliding in the slide groove, which requires manual adjustment, so it needs to be adjusted before adding the transfer liquid, and the amount of transfer liquid added may be different from the original estimate, resulting in the height of the cross arm inside being not the optimal height, resulting in unsatisfactory defoaming effect.

[0004] This case was created to solve the above problems. Utility Model Content
