Embodiment Construction
[0024] Below in conjunction with accompanying drawing, technical scheme of the present invention is described as follows:
[0025] Such as figure 1 As shown, the heat insulation device of the refining equipment in the furnace of the present invention includes a left heat insulation board 1, a middle heat insulation board 2 and a right heat insulation board 4. There are two hinge points on the left and right sides of the middle heat insulation board 2, and the left heat insulation board There are 2 hinge points on the right side of the board, and 2 hinge points on the left side of the right heat shield board. The left heat shield board 1 and the right heat shield board 4 are respectively hinged on the left and right sides of the middle heat shield board 2 through 2 hinge points. At the hinge point, the left and right sides of the middle heat shield 2 are respectively hinged with the left heat shield 1 and the right heat shield 4; the bottom end of the middle heat shield 2 is hi...

The invention discloses a thermal insulation device of in-furnace refining equipment. The thermal insulation device comprises a left thermal insulation plate, a middle thermal insulation plate and a right thermal insulation plate. The bottom end of the middle thermal insulation plate is hinged to the front end of a mounting support of a stirring mechanism; the left side and right side of the middle thermal insulation plate are hinged to the left thermal insulation plate and the right thermal insulation plate correspondingly; telescoping mechanisms are hinged to the rear portion of the left thermal insulation plate and the rear portion of the right thermal insulation plate correspondingly; the telescoping mechanisms are disposed on the mounting support of the stirring mechanism; and a through hole out of which a stirring shaft of the stirring mechanism extends is formed in the middle thermal insulation plate. By means of the thermal insulation device, in-furnace thermal radiation can be effectively stopped, temperature drop of a melting furnace or a holding furnace is reduced, a machine body of the in-furnace refining equipment is protected against overheating, and meanwhile, the tail end of the high-temperature stirring shaft is cooled through low-temperature air flow which is fed into thermal insulation shields through a fan, so that the effect that overheating of the stirring mechanism is avoided is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of processing equipment for molten aluminum, in particular to a heat insulation device for refining equipment in a furnace. Background technique [0002] In the aluminum processing and aluminum casting industry, in order to produce high-quality aluminum alloy products, it is usually necessary to reduce the content of hydrogen, alkali metals and non-metallic inclusions in the molten aluminum liquid in the melting furnace or holding furnace. The most advanced and efficient equipment currently used to realize this process is furnace refining equipment. [0003] The furnace door needs to be opened during the working process of the refining equipment in the furnace, but when the furnace door is open, the melting furnace or holding furnace will radiate and lose a large amount of heat to the external environment through the furnace door, which will reduce the temperature of molten aluminum, which will affect the su...
