Description

Technical Field

[0001] The utility model relates to the technical field of colloid preparation devices, in particular to a preparation device for colloid chemicals. Background Art

[0002] Fe(OH)3 is a colloid that is often prepared in the laboratory. During the preparation of Fe(OH)3, the distilled water in the beaker needs to be heated to boiling, and then FeCl3 is dripped into the boiling distilled water through a dropper. After further boiling, the liquid in the beaker becomes reddish brown, and the preparation of Fe(OH)3 colloid is completed.

[0003] However, during the boiling process of distilled water, the water surface will roll. When the operator drops FeCl3, if he does not control the height well, the dripping FeCl3 saturated solution will collide with the hot water, causing water to splash. Some of the water will fly out of the beaker and come into contact with the operator's skin, easily causing burns to the operator. Utility Model Content

The splash cover 2, as a truncated cone, can raise the insertion tube 3, thereby maintaining the distance between the dropper and the beaker 1 to ensure the height required for the dropper to drip. The splash cover 2, the insertion tube 3 and the reflux plate 6 are cast in one piece. The diameter of the reflux plate 6 is 0.98 times the diameter of the beaker 1, so that the splashed liquid will stick to the inner wall of the splash cover 2, and under the action of gravity, it will slide to the reflux plate 6, and be guided by the reflux plate 6 to flow to the inside of the beaker 1 to ensure that the liquid will not overflow from the gap between the splash cover 2 and the beaker 1. The reflux plate 6 is annular, and the reflux plate 6 extends out of the bottom end of the splash cover 2 by 2-3 cm. The diameter of the first circular through groove of the insertion tube 3 is twice the diameter of the dropper, so as to facilitate the insertion of the dropper.
