Description

Technical Field

[0002] The reducing agent is a substance that loses electrons in the redox reaction. In a broad sense, the reducing agent itself is also an antioxidant and has reducing properties. When oxidized, its product is called an oxidation product. The reduction and oxidation reactions are carried out simultaneously, that is, while the reducing agent is undergoing a reduction reaction with the reduced substance, it is also oxidized and becomes an oxide. The reactant with a certain substance whose valence increases is the reducing agent. The feeding mechanism is usually used in the processing of denitrification reducing agents, which is convenient for processing the reducing agent and improves work efficiency.

The utility model can not only spray the reducing agent evenly in the dilution barrel through the coordinated use of the guide tube and the storage bag, and reduce the use of manual labor, but also can change the degree of squeezing of the storage bag by the pressing block by moving the force frame, which is conducive to controlling the amount of outflow of the storage bag, and can also help the flow of liquid in the dilution barrel by rotating the stirring frame, thereby improving the practicality of the mechanism.
