AI Technical Summary

Technical Problem

Existing crystal growth devices are prone to bubbles when replenishing solutions into the reaction vessel, resulting in deformity in crystal growth, holes or cracks, and affecting crystal quality.

Method used

A continuous feeding device for crystal growth is designed. By setting an inner baffle and a filter in the reaction vessel, a crystallization area and a liquid replenishment area are formed. The filter filters and intercepts the bubbles to ensure that the crystal growth solution does not produce bubbles in the crystallization area.

Benefits of technology

It effectively avoids the occurrence of crystal growth deformities, holes or cracks, ensures the overall quality of the crystal, and realizes automatic control of solution replenishment through the liquid level meter and signal transmission system to ensure the stable output of high-quality crystals of the device.

Abstract

The utility model discloses a crystal growth continuous feeding device which comprises an operation box and a reaction container, the bottom wall of the reaction container protrudes upwards to form an inner baffle, the inner baffle enables a crystallization area and a liquid supplementing area to be formed in the reaction container, the top of the inner baffle is fixedly connected with a filter screen, and the top end of the filter screen is lower than the top end of the reaction container. A heater is arranged outside the crystallization area; a liquid conveying pipe is connected to the bottom side of the liquid box, the free end of the liquid conveying pipe is arranged in the liquid supplementing area, and the bottom end of the crystal block is arranged in the crystallization area. According to the utility model, a crystal growth solution is injected into the liquid supplementing area, and along with the rising of the liquid level in the liquid supplementing area, when the liquid level exceeds the inner baffle plate, the solution flows into the crystallization area, liquid supplementing is carried out on the crystallization area, and bubbles are filtered and intercepted by the filter screen, so that the crystal growth solution supplemented in the crystallization area does not generate bubbles; crystal growth malformation is avoided, holes or cracks are formed, and it is guaranteed that the whole device can stably output high-quality crystals.
