AI Technical Summary

Technical Problem

Existing salt crystallizers directly heat the salt slurry through heating tubes, resulting in high surface temperatures of the heating tubes. This can easily lead to localized overheating of the nearby salt slurry, rapid evaporation of moisture, scaling, reduced heating efficiency, increased energy consumption, and shortened lifespan of the heating tubes.

Method used

It adopts a heating method combining heat-conducting plates and electric heating plates, and is equipped with a cleaning component and an auxiliary exhaust component. The heat-conducting plate is seamlessly connected to the cylinder, and the electric heating plate is in close contact with the lower surface of the heat-conducting plate. The cleaning component rotates with the stirring component to remove salt crystals on the surface of the heat-conducting plate, and the auxiliary exhaust component accelerates the gas discharge to prevent scale formation.

Benefits of technology

Improve heating efficiency, reduce energy consumption, prevent scale buildup from damaging heating components, extend the service life of heat-conducting plates, and reduce the erosion of the device by high-temperature hot air.

Abstract

The application provides a crystallization device for salt production, and relates to the technical field of crystallization. The device comprises a cylinder with an opening at the bottom and a heating assembly arranged at the opening of the bottom of the cylinder. The heating assembly comprises a heat-conducting plate, an electric heating plate and a protective plate. The heat-conducting plate is seamlessly connected to the bottom of the cylinder. The electric heating plate is arranged close to the lower surface of the heat-conducting plate. The protective plate is arranged close to the lower surface of the heat-conducting plate. An exhaust pipe is connected to the top of the cylinder. A salt slurry injection pipe is connected to one side of the cylinder. A stirring assembly is rotatably arranged in the cylinder. The device adopts a heating mode combining the heat-conducting plate and the electric heating plate, which can effectively heat and protect the electric heating plate. The cleaning assembly can rotate with the stirring assembly, timely remove the salt crystals on the surface of the heat-conducting plate and effectively prevent the formation of scale. Compared with the prior art, the device can improve the heating efficiency, reduce energy consumption, avoid damage of the heating assembly caused by scale and prolong the service life of the heat-conducting plate.
