AI Technical Summary

Technical Problem

Existing quartz crucible melting equipment has a slow and uneven heating rate during the heating process, and cannot perform multi-point heating according to the size of the crucible, resulting in low preparation efficiency.

Method used

A three-section conical discharge tower structure is adopted. By setting three sets of positive graphite electrode rods and three rings of negative graphite electrode rods, a multi-layer heating zone is formed. The distance and angle of the electrode rods are adjusted by using a lifting frame and a negative electrode displacement component to achieve uniform heating.

Benefits of technology

It heats up faster, distributes heat more evenly, and can adapt to the needs of preparing crucibles of different sizes, thus improving preparation efficiency.

Abstract

The invention discloses quartz crucible melting equipment, and relates to the technical field of crucible melting. The device comprises a lifting hanging bracket, a mounting plate, a positive pole mounting assembly and a negative pole displacement assembly, the positive pole mounting assembly is mounted below the mounting plate through a connecting rod group, the positive pole mounting assembly comprises a positive pole ceramic sleeve, and three groups of positive pole graphite electrode bars are arranged on the positive pole ceramic sleeve; the mounting plate is provided with three circles of uniformly arranged cathode displacement assemblies, and the bottom end of the cathode graphite electrode bar surrounds the bottom end of the anode graphite electrode bar to form a conical discharge tower. By arranging the three structural layer positive graphite electrode bars and the three circles of negative graphite electrode bars, three groups of conical discharge towers are formed, a larger heating area can be formed, and the problems that existing heating is conducted at one point position, the heating speed is low, and heating is unbalanced are solved.
