technical field

The invention relates to the field of chemical solution preparation devices, in particular to a self-sealing quantitative feeding mechanism.

Background technique

At present, in the general industrial chemical production process, when a solution needs to be prepared, it is necessary to calculate the amount of raw materials per unit time, and then select a container with a corresponding capacity for the preparation of the solution. During the preparation of the solution, if the solute is a powdery material, then It is necessary to accurately measure the amount of the powdery solute first, then slowly pour it into the pre-prepared container manually, and at the same time use manual stirring to fully dissolve the powdery solute and the solvent. This mode of operation will cause the volume of the required equipment to be too large. The configuration takes a long time, and in the process of mixing the solute and the solvent into a solution, the solution will splash due to the chemical reaction, which brings safety hazards to the operator.
