Description

Technical Field

[0001] The utility model relates to the technical field of aluminum sulfate production, in particular to a cooling device for aluminum sulfate production. Background Art

[0002] Aluminum sulfate is an inorganic compound, a white crystalline powder. It is used as a precipitant for rosin glue, wax emulsion and other sizing materials in the papermaking industry, as a flocculant in water treatment, and as an internal retention agent in foam fire extinguishers. It is also a raw material for making alum and aluminum white, and a raw material for petroleum decolorizing, deodorizing agents, and medicines.

[0003] The production process of aluminum sulfate is mostly as follows: crush aluminum ore into particles, place in a reactor, add sulfuric acid of a certain concentration; stir for several hours to allow it to fully react chemically; cool and dilute the solid-liquid mixture obtained by the reaction, and send it to a sedimentation tank through a conveying pipeline. During the production process of liquid aluminum sulfate, a cooling device is required to reduce the temperature of the liquid aluminum sulfate. During the production process, it is generally cooled by natural cooling or fans, which makes the heat dissipation effect poor, resulting in relatively low cooling efficiency, affecting the production of aluminum sulfate.

The output end of the driving motor passes through the tank body and is fixedly connected to a rotating rod, which extends to the bottom of the tank body.
