Description

technical field [0001] The invention relates to a mechanism for on-line detection of the position of a material basket for solar gravity heat pipe annealing in a multi-chamber vacuum furnace, in particular to a mechanism for on-line detection of the position of the material basket of a three-chamber automatic continuous vacuum furnace. Background technique [0002] Heat pipes are widely used in solar water heaters and solar water heating systems. The heat pipe is a high-efficiency heat transfer device that uses the working fluid to transfer heat in disguise. It has a large thermal conductivity and good temperature uniformity. Generally, copper (oxygen-free copper TU1) is used as the shell material. In the manufacturing process of the copper shell heat pipe, in order to improve its toughness and facilitate the subsequent inspection process, vacuum annealing and degassing treatment is required. Most of the existing annealing equipment is a single-chamber vacuum furnace, and th...

Problems solved by technology

In the manufacturing process of the copper shell heat pipe, in order to improve its toughness and facilitate the subsequent inspection process, vacuum annealing and degassing treatment is required. Most of the existing annealing equipment is a single-chamber vacuum furnace, and the annealing adopts the method of manual feeding and reclaiming. After the copper tube enters the vacuum furnace, it needs to complete the process of vacuuming, heating, heat preservation, and cooling in the furnace, which has problems such as low efficiency, easy pollution, and high energy consumption.

Some people are trying to develop an automatic continuous vacuum furnace, which adopts the continuous processing method of three chambers (preparation feeding chamber, vacuum heating chamber, cooling chamber). The vacuum heating chamber is always in a high temperature and high vacuum state to avoid external pollution and save repeated Vacuuming, repeated heating and cooling time can ensure the needs of mass production, but because the vacuum heating chamber is always in a state of high vacuum and high temperature when working, it has become a technical difficulty to accurately detect the position of the workpiece basket in the vacuum heating chamber
