A gas pressure stabilizing device for an electric furnace used in the production of quartz drawn tubes

Abstract

The invention discloses an air pressure stabilizing device for an electric furnace used in the production of quartz drawn tubes. The exhaust pipe is provided with a pressurized air pump on one side of the outer wall of the gas storage tank, and three pressure regulating structures are arranged at the left end of the gas storage tank, and the pressure regulating structures are connected with corresponding exhaust pipes. The pressure regulating structure includes a pinch plate, the pinch plate is in the shape of a long strip, and a strip-shaped groove is opened in the middle of the pinch plate, and the two sides of the top of the pinch plate are symmetrically provided with clamping plates, which are embedded in the inner sides of the two clamping plates. There is a sliding mixing tank. In the present invention, by adding three exhaust pipes and a pressure regulating structure at the left end of the gas storage tank, the gas inside the gas storage tank can be discharged into the mixing tank on the three pressure regulating structures by using a pressurized air pump, and can be passed through The hydraulic cylinder adjusts the position, and the air pressure inside the electric furnace is quickly adjusted by using the pressurized air pipe and the 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
