Intelligent temperature control type heating furnace for preparing low-hydroxyl quartz glass

Abstract

The invention discloses an intelligent temperature control type heating furnace for preparing low-hydroxyl quartz glass, which comprises a cuboid heating furnace, a heat insulation plate is arranged in the heating furnace, a guide rail is arranged at the top of the heat insulation plate, and a heating frame structure is slidably connected to the top of the heat insulation plate. A temperature adjusting control assembly is arranged at the top of the heating furnace, a plurality of casting blocks used for heat conduction are arranged on the outer wall of the heating furnace at equal intervals, waste heat recovery structures are arranged between the adjacent casting blocks, the temperature adjusting control assembly comprises a cover plate, and a long-strip-shaped protruding column is arranged at the top of the cover plate. The interior of the convex column is hollow and is provided with a plurality of storage cavities, gas storage tank bodies are symmetrically arranged on the two sides of the top of the cover plate, a plurality of storage chambers are arranged in the gas storage tank bodies at equal intervals, and a plurality of base plates are arranged on the inner wall of the cover plate at equal intervals. The quartz glass can be heated in a temperature control mode, waste heat can be recycled, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of quartz glass processing equipment, in particular to an intelligent temperature-controlled heating furnace for preparing low-hydroxyl quartz glass. Background technique [0002] Quartz glass is made by melting various pure natural quartz (such as crystal, quartz sand, etc.). The linear expansion coefficient is extremely small, which is 1 / 10-1 / 20 of ordinary glass, and has good thermal shock resistance. Its heat resistance is very high, the temperature for regular use is 1100℃-1200℃, and the temperature for short-term use can reach 1400℃. Quartz glass is mainly used in laboratory equipment and refining equipment for special high-purity products. Because of its high spectral transmission, it is not damaged by radiation, so it is also an ideal glass for use in spacecraft, wind tunnel windows and spectrophotometer optical systems. [0003] Quartz glass is a special industrial technical glass with a single c...
