AI Technical Summary

Technical Problem

Existing salt lake brine evaporation and crystallization devices cannot simultaneously achieve crystal crushing, stirring, and tank inner wall cleaning, resulting in crystals adhering to the tank inner wall and causing evaporation crystals to accumulate and clump at the bottom of the tank, leading to unsatisfactory evaporation and crystallization effects.

Method used

The system employs a composite component, including a stirring rod, a support rod, a vertical plate, and scraper blades. The staggered shearing force of the stirring blades agitates the brine in the salt lake, while the scraper blades scrape off crystals. The rake teeth prevent sedimentation and clumping, and the stirring blades break up large crystals, achieving effective agitation and cleaning.

Benefits of technology

It effectively prevents crystals from adhering to the inner wall of the tank, prevents sedimentation and clumping, improves the evaporation and crystallization effect, and allows the brine inside large crystals to flow out smoothly, thus improving the efficiency and effectiveness of evaporation and crystallization.

Abstract

The utility model provides a kind of salt lake brine evaporation crystallization device, belong to salt lake resource development technical field. Including double-layer crystallizing tank, double-layer crystallizing tank is equipped with composite component, composite component includes stirring rod, and the upper and lower ends of the rod body of stirring rod are symmetrically equipped with support rod, and vertical plate is equipped between the end of same side support rod, and a plurality of scraper leaves that are attached to the inner wall of double-layer crystallizing tank and are arranged obliquely are equidistantly arranged on the side wall of vertical plate, and a plurality of peg harrow teeth are equidistantly arranged on the bottom of lower support rod. The utility model is stirred by composite component, stirring blade one and stirring blade two to salt lake brine, and the crystallization adhered on the inner wall of double-layer crystallizing tank is scraped off by scraper leaf, to prevent evaporation crystallization from adhering to the inner wall of tank, which is beneficial to subsequent cleaning, peg harrow teeth continuously turn the bottom crystal close to tank bottom, to prevent sedimentation from caking, and stirring blade one and stirring blade two are matched to break and crack large crystallization, so that the salt lake brine inside large evaporation crystallization is discharged, and the evaporation crystallization effect is more ideal.
