AI Technical Summary

Technical Problem

The heat inside the crystallization furnace is rapidly dissipated, resulting in a large number of small crystal nuclei precipitated, which is not conducive to the growth of the crystal.

Method used

A crystallization furnace insulation device is designed, including a hollow shell, annular insulation tube, a hot water component and a vacuum shell layer. The hot water is circulated through the annular insulation tube, and the vacuum shell layer suppresses heat dissipation, delays heat loss, and maintains the heat in the crystallization furnace.

Benefits of technology

Effectively prevent the heat in the crystallization furnace from dissipating rapidly, avoiding the sudden drop in temperature, reducing the precipitation of small particles of crystal nuclei, which is conducive to the growth of crystals and improving crystallization efficiency.

Abstract

The utility model provides a heat preservation device of a crystallization furnace and belongs to the technical field of crystallization furnaces. Comprising a crystallization furnace body, a stirring assembly is arranged in the crystallization furnace body, a hollow shell is arranged on the outer furnace wall of the crystallization furnace body, an annular heat preservation pipe is arranged in the hollow shell, a hot water supply assembly communicated with the annular heat preservation pipe is arranged at the top of the crystallization furnace body, and a vacuum shell layer is arranged on the outer wall of the hollow shell; the hot water supply assembly comprises a water storage tank, a water pump is arranged in the water storage tank, and a water outlet pipe communicated with the upper ring pipe is arranged on the side wall of the water pump. Under the combined action of the hollow shell, the vacuum shell layer, the annular heat preservation pipe, the hot water supply assembly and the like, high-temperature heat in the crystallization furnace is relatively slowly dissipated outwards through the hollow shell and the vacuum shell layer, the heat in the crystallization furnace can be prevented from being quickly dissipated outwards, the heat preservation effect is good, a large number of small-particle crystal nucleuses are prevented from being separated out due to sudden temperature drop, and the service life of the crystallization furnace is prolonged. The crystal growth is facilitated.
