Fully automatic continuous vacuum furnace

Abstract

The invention discloses a full-automatic continuous vacuum furnace and solves the technical difficult problems of low efficiency, high possibility of pollution and high energy consumption of conventional heating pipe annealing equipment. The vacuum furnace comprises a preparation feeding chamber (20), a vacuum heating chamber (1) and a cooling chamber (25), wherein a vacuum heating chamber roller transmission system (3) and a charging basket (4) are arranged in the vacuum heating chamber (1); a sealed detection rotary shaft bearing seat (5) and a brass shaft sleeve (7) are arranged on the side wall of the vacuum heating furnace; a charging basket position detection rotary shaft (9) is movably arranged in the brass shaft sleeve; the inner side of the charging basket position detection rotary shaft penetrates the side wall of the vacuum heating chamber (1) and a vacuum heating chamber furnace pipe (2) in sequence to be connected with a T-shaped detection rod (10); the T-shaped detection rod is arranged above the vacuum heating chamber roller transmission system (3); a sealed detection barrel body (14) is connected to the outer side of the detection rotary shaft bearing seat (5); a position switch (17) is arranged in the sealed detection barrel body. Therefore, the vacuum heating pipe annealing efficiency is improved and the vacuum heating pipe annealing quality is guaranteed.

Description

technical field [0001] The invention relates to a vacuum furnace for annealing a solar gravity heat pipe, in particular to a continuous vacuum furnace for performing three-chamber automatic continuous vacuum annealing on a material basket equipped with a solar gravity heat pipe. Background technique [0002] In solar water heating systems, heat pipes are widely used. 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 the annealing adopts the method of manual feeding and reclaiming. After the copper...
