Description

Technical Field

[0001] The utility model relates to the field of mother liquid evaporators, in particular to a mother liquid evaporator. Background Art

[0002] Mother liquor refers to the saturated solution remaining after the precipitate or crystals are separated from the solution during the chemical precipitation or crystallization process. In experiments, mother liquor can also refer to the highly concentrated liquid obtained when preparing chemical substances, or the liquid used to prepare nutrient media, such as culture media. In industrial production, the mother liquor wastewater generated generally needs to be dried through steps such as evaporation to obtain the residual material in the kettle, so as to avoid direct discharge of the mother liquor and cause environmental pollution.

[0003] Chinese patent publication number CN206793191U discloses a centrifugal dispersed sea salt mother liquor filtration device, including a crystal concentration collection box, a centrifugal filter cartridge, a sea salt mother liquor filter tank and a hollow rotating shaft. The sea salt mother liquor filter tank is assembled on a support frame, and a fixing ring is installed on the inner wall of the sea salt mother liquor filter tank. This device facilitates the collection of sea salt mother liquor crystals. The filtered sea salt mother liquor is prevented from further precipitation of crystals under the stirring rod, thereby improving the filtration of the sea salt mother liquor. However, after the evaporator has been used for a period of time, a large amount of material will be adhered to the inner wall of the evaporator, which will seriously affect the evaporation accuracy. To this end, we propose a mother liquor evaporator to solve the above problem. Utility Model Content
