Electric furnace air pressure stabilizing device for quartz tube drawing production

Abstract

The invention discloses an electric furnace air pressure stabilizing device for quartz tube drawing production. The device comprises an air storage tank, the air storage tank is cylindrical, a sealing cover is arranged at the right end of the air storage tank, three exhaust pipes are arranged at the left end of the air storage tank, and a pressurizing air pump is arranged on one side of the outer wall of the air storage tank. Three pressure regulating structures are further arranged at the left end of the air storage tank, the pressure regulating structures communicate with the corresponding exhaust pipes, each pressure regulating structure comprises a long-strip-shaped buckle plate, a strip-shaped groove is formed in the middle of each buckle plate, clamping plates are symmetrically arranged on the two sides of the top of each buckle plate, and a slidable mixing tank is embedded into the inner sides of the two clamping plates. The three exhaust pipes and the pressure regulating structures are additionally arranged at the left end of the air storage tank, gas in the air storage tank can be exhausted into the mixing tank on the three pressure regulating structures through the pressurizing air pump, the position can be adjusted through a hydraulic cylinder, and the gas pressure in an electric furnace is rapidly adjusted through a pressurizing gas pipe and an exhaust structure.

Description

technical field [0001] The invention relates to the technical field of quartz tube-drawing production equipment, in particular to an air pressure stabilizing device for an electric furnace used in quartz tube-drawing production. Background technique [0002] Quartz tube is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. It is used in electric fire barrels, electric ovens, and electric heaters to generate heat. Quartz tubes can be roughly divided into the following types: transparent quartz tubes (outer diameter 1.5mm-300mm), UV filter quartz tubes, colored quartz tubes, etc. A quartz tube is used for closed-tube diffusion. This is because the quartz tube can withstand a high temperature of about 1250°C, and it will become very soft and sticky when it is above 1800°C, and can be made into the desired shape. On the other hand, since the raw material of the quart...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electric furnace pressure stabilizing device for quartz tube production, which solves the problem that: during the processing and production of quartz tubes, the pressure of the electric furnace is adjusted. Using a single gas for pressure regulation, the overall pressure regulation is not fast enough, which affects the effect of pressure regulation, resulting in a lower pass rate of processed products
