[0002] Waste aluminum sulfate generally refers to waste containing aluminum sulfate generated during the production or use process. Aluminum sulfate is a solid chemical substance, usually colorless crystals or white crystals. In industrial production, such as water treatment, metallurgy and other processes, wastewater or solid waste containing aluminum sulfate will be generated.

[0003] The existing waste aluminum sulfate recovery is to first filter the waste aluminum sulfate solution through a filter disk, then add sodium hydroxide to the waste aluminum sulfate solution to react and form solid aluminum sulfate, then take out the solid aluminum sulfate, and then take out the remaining aluminum sulfate solution for recycling. Since the aluminum sulfate solution needs to be recycled repeatedly by manual labor, the aluminum sulfate solution cannot be directly recycled to prepare solid aluminum sulfate, which affects the recovery efficiency of the waste aluminum sulfate solution and is relatively inconvenient.

[0007] In one of the embodiments, a slag discharge pipe and a valve are also included. The lower side of the collecting hopper is connected to the slag discharge pipe, and the middle part of the slag discharge pipe is rotatably connected to the valve.
