Description

Technical Field

[0001] The utility model relates to the technical field of collector glass tubes, and specifically relates to a sealed annealing box for the production of collector glass tubes. Background Technique

[0002] A collector glass tube refers to a heat absorber composed of three concentric glass tubes, namely an inner tube, a middle tube, and an outer tube, with the characteristics of high absorptivity and low emissivity. Since the raw materials used in such collectors are abundant, glass tubes with corrosion resistance and resistance to sunlight irradiation are used instead of metals as structural materials, which can not only save resources, reduce costs, but also extend the service life.

[0003] When processing collector glass tubes, annealing treatment needs to be carried out on the collector glass tubes to improve the strength of the collector glass tubes and achieve the tight connection between the three concentric glass tubes, namely the inner tube, the middle tube, and the outer tube.

[0004] However, when the existing annealing boxes are in use, generally the materials are directly placed in the annealing boxes and heated with gradual cooling to achieve the annealing operation. Such an annealing method is likely to cause uneven heating of the materials, resulting in stress change damage, and is not convenient for discharging the heated hot air or soot, etc. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sealed annealing box for the production of collector glass tubes, which has the advantages of driving the annealing materials to rotate for heating and annealing, improving the uniform heating of the materials, maintaining the same stress, discharging hot air or soot through a guide, improving the smoke exhaust efficiency, and being convenient for adjustment and control, so as to solve the problems raised in the above background technique.
