Problems solved by technology

When the quartz crucible 3 is in operation, the temperature between the crucible and the molten glass reaches more than 1,000 degrees Celsius, and the part in contact with the bottom of the crucible and the flat-bottomed water plug has a low local temperature due to the cooling effect of the water plug. Explosion occurs, damages the quartz crucible 3, and causes leakage at the bottom of the crucible, which affects production efficiency and increases production costs

Embodiment Construction

[0013] Such as figure 2 Shown. The present invention is installed on the water plug support, through the upward elastic pressing force of the spring, the cone surface of the water plug body 7 is close to the leakage opening 1 of the quartz pot 3, and the cone surface of the water plug body 7 has an automatic centering function. It not only meets the work needs, but also ensures the consistency of the quartz pot temperature. When the quartz preparation furnace is working, the water plug blocks the leaking port, the raw materials are melted into glass liquid 2 at high temperature, and the water plug circulates in the cooling water through the water inlet pipe 6 and the water outlet pipe 5 to cool the water plug, thereby protecting the water plug The role of. The water plug body 7 is a heat-resistant stainless steel product with a diameter of about φ40mm, an axial hollow (wall thickness not less than 3.5mm), and closed ends. The lower end of the water plug body 7 is provided w...

Abstract

The name of the invention is a water stemming of a discharge hole of a quartz crucible material-preparation furnace. The invention belongs to the technical field of material preparation of environment-friendly optical glass and lanthanide optical glass. The invention mainly solves the problem of cracking of a crucible bottom when a quartz crucible is used to prepare raw materials of environment-friendly optical glass or lanthanide optical glass at present. The main characteristics are that: the water stemming comprises a water stemming body, and an inlet pipe and an outlet pipe which are disposed on a lower end surface of the water stemming body; an upper end surface of the water stemming body is a conical surface fitted to a discharge hole with a cone angle of 110 DEG-130 DEG; the water stemming body is made of heat-resistant stainless steel with an external diameter of phi 36-phi 45 mm, a wall thickness of not less than 3.5 mm, and an upper end surface thickness of not less than 4 mm; an upper port of the outlet pipe is higher than an upper port of the inlet pipe by 8 mm-12 mm. The invention is characterized in that: the invention not only meets the production requirements of a quartz crucible material-preparation furnace, but also effectively protects the quartz crucible, reduces production cost, and improves production efficiency, and the invention is mainly used to plugging the discharge hole at the crucible bottom when a quartz crucible is used to prepare raw materials of environment-friendly optical glass or lanthanide optical glass.

Description

Technical field [0001] The invention belongs to the technical field of preparation of environmentally friendly optical glass and lanthanide optical glass raw materials. Specifically, it relates to a water plug for a material leakage port at the bottom of the pot when the quartz pot is used to prepare environmentally friendly optical glass or lanthanide optical glass raw materials. Background technique [0002] Quartz preparation furnace is mainly used for the first smelting preparation of environmentally friendly optical glass and lanthanide optical glass, to solve the problems of coloring and light fluctuation caused by optical glass primary materials. It uses silicon molybdenum rods as heating materials, and the working temperature is between 1100°C and 1500°C. It uses a quartz pot with an opening at the bottom as a preparation container. The bottom hole (leakage) of the pot needs to be blocked during operation, and the raw material is melted. If it can be easily discharged fr...
