Magnesium sulfate crystallization device

Abstract

The invention relates to a magnesium sulfate crystallization device. The magnesium sulfate crystallization device comprises a crystallization furnace, wherein a pair of feeding inlets are arranged onthe crystallization furnace; a discharge outlet is arranged at the bottom part of the crystallization furnace; a motor is fixedly arranged at the top part of the crystallization furnace and connectedwith a stirring rod; a partition plate dividing the space of the interior of the crystallization furnace into an upper layer and a lower layer is arranged in the crystallization furnace; the interiorof the crystallization furnace is divided into a crystallization area and a storage area by the partition plate; an opening is arranged at the middle part of the partition plate; a sealing unit used for sealing the opening is arranged in the storage area; and a discharging unit used for opening and closing the discharge outlet is arranged at the bottom part of the crystallization furnace. According to the invention, the interior of the crystallization furnace is divided into the crystallization area and the storage area through the partition plate; crystallization of a solution placed in the crystallization area is completed; crystals are injected into the storage area to be stored; and discharging can be performed after a plurality of times of crystallization. A sealing block is driven byan electric push rod to seal the opening, so a magnesium sulfate solution is prevented from accidentally leaking into the storage area during crystallization. Through an opening and closing mechanismand a disc, the disc is driven to open and close the discharge outlet for discharging.

Description

technical field [0001] The invention relates to magnesium sulfate production and processing equipment, in particular to a magnesium sulfate crystallization device. Background technique [0002] Traditional magnesium sulfate is produced by sulfuric acid method. To obtain magnesium sulfate crystals, it is necessary to evaporate and crystallize the reacted magnesium sulfate solution. In traditional crystallization devices, the next crystallization can only be carried out after the crystallization is completed and the crystals are completely discharged. The process It takes a long time and the labor intensity of the workers is high. Since the volume of magnesium sulfate crystals crystallized at one time occupies a small volume of the crystallization tank, magnesium sulfate is produced in large quantities, and the crystallization process takes too long. Therefore, a magnesium sulfate crystallization device is needed to solve the above problems. Contents of the invention [0003...

Problems solved by technology

[0002] Traditional magnesium sulfate is produced by sulfuric acid method. To obtain magnesium sulfate crystals, it is necessary to evaporate and crystallize the reacted magnesium sulfate solution. In traditional crystallization devices, the next crystallization can only be carried out after the crystallization is completed and the crystals are completely unloaded. It takes a long time and the labor intensity of the workers is high. Since the volume of magnesium sulfate crystals crystallized at one time occupies a small volume of the crystallization tank, magnesium sulfate is produced in large quantities, and the crystallization process takes too long. Therefore, a magnesium sulfate crystallization device is needed to solve the above problems
