Evaporation and concentration device for potassium chloride production

The utility model relates to an evaporation concentration device for potassium chloride production, which comprises a tank body, an upper cover, a power assembly, a water spraying assembly and an impurity cleaning assembly, the upper cover seals the upper side of the tank body, the power assembly is arranged above the upper cover, the water spraying assembly is a coil pipe with a plurality of nozzles, and the water spraying assembly performs lifting motion along a straight line under the action of the power assembly. And spraying water to the inner side wall of the tank body to clean the side wall. Therefore, after the work of evaporating and concentrating potassium chloride is finished, an air cylinder in the power assembly is started, water sprayed by the water spraying assembly is used for cleaning, impurity precipitates can be quickly dissolved in the water, and then sewage with dissolved impurities is discharged, so that the impurities can be efficiently cleaned, and the problem that after the work of pu
