Technical Field

[0001] The utility model belongs to the field of sewage treatment, and in particular relates to an automatic dispensing device for polyaluminium chloride flocculant. Background Art

[0002] In the field of packaging of polyaluminium chloride flocculants, the existing automatic packaging machine mechanical structure has realized the basic packaging function. Through a series of mechanical transmission and positioning mechanisms, the flocculant is transferred from the storage container to the packaging container. However, although these mechanical structures meet the packaging needs to a certain extent, they still expose some potential deficiencies in actual applications.

[0003] The existing mechanical structure of the automatic polyaluminium chloride flocculant dispenser is not convenient for controlling the amount of aluminium chloride flocculant added during the dispensing process, resulting in excessive or insufficient dosage of aluminium chloride flocculant during dispensing, and the problem of uneven concentration of aluminium chloride flocculant exists during the dispensing process.

[0004] Therefore, in order to address the problems of insufficient filling accuracy and adaptability of the mechanical structure of the above-mentioned polyaluminum chloride flocculant automatic dispenser, a stirring component and a controllable automatic quantitative feeding structure are designed to reduce the error of the aluminum chloride flocculant filling method and improve stability.
