Description

Technical Field

[0001] The utility model relates to the technical field of alumina production, in particular to a device for preparing a flocculant for alumina production. Background Art

[0002] The preparation of flocculants for alumina production typically involves selecting suitable raw materials, such as polyaluminium chloride (PAC), hydrating and granulating them to increase their activity. The raw materials are then dissolved in water to create a solution of the desired concentration, which is then used to improve the settling properties of the slurry, thereby increasing the efficiency of alumina extraction.

[0003] The prior art patent document with publication number CN211800755U provides a device for preparing a flocculant for alumina production. The device includes a reaction tank, an expansion tank and an ethanol absorption tank. The reaction tank includes a tank body, a jacket, a stirring device and a temperature detection component, which can realize the control of reaction conditions and the stability of the reaction system. At the same time, ethanol is used to absorb exhaust gas to realize pollution-free production of flocculant. Although the device has many beneficial effects, it still has the following problems: the overall setting of the reaction tank body of the device is relatively simple, and the heat inside it is easy to diffuse outward through the tank wall, which is not conducive to the temperature control inside the tank body, and thus easily affects the preparation of the flocculant, and is not convenient for the use of the device for preparing the flocculant for alumina production. For this reason, we propose a device for preparing a flocculant for alumina production. Utility Model Content
