Description

Technical Field

[0001] The utility model relates to the technical field of sodium metaaluminate preparation, in particular to a reaction kettle for preparing sodium metaaluminate. Background Art

[0002] Sodium aluminate, an alkaline substance with the chemical formula NaAlO2, is a white granule, hygroscopic, highly soluble in water, insoluble in ethanol. Its aqueous solution is strongly alkaline and can be used in water treatment as a water purifier additive. It can also be mixed with water glass for plugging leaks during construction. Sodium aluminate can generally be prepared using a reactor.

[0003] For example, a reaction kettle for preparing a sodium aluminate solution with publication number CN219051352U includes a reaction kettle shell, in which undissolved materials continuously enter the stirring shell through the reflux hole during the circulation process and are then intercepted by the filter plate, so that the undissolved materials are continuously collided by the high-speed rotating propeller blades in the narrow stirring shell to accelerate the dissolution rate;

[0004] The reactor for preparing sodium aluminate solution has a detachable upper cover installed above the reactor shell, and the sodium aluminate solution is prepared in cooperation with a stirring shell and a stirring shaft in the reactor shell. However, since no fixed structure is provided between the reactor shell and the upper cover, when the motor drives the stirring shaft and the propeller blades to rotate, the stirring shaft and the propeller blades will drive the internal liquid to perform centrifugal motion, and hit the inner wall of the reactor shell, etc., so that the reactor shell shakes, which makes it easy for the upper cover above the reactor shell to move, causing the structure connected to the upper cover to collide with the inner wall of the reactor shell and be damaged. At the same time, no heat-insulating structure is provided on the outer wall of the reactor shell in the above method. In this way, when the liquid flows into the reactor shell from the stirring shell, the heat in the liquid will still be conducted to the outside through the reactor shell, causing heat loss. In view of this, it is very necessary to design a reactor for preparing sodium aluminate to solve this problem. Utility Model Content
