Each time the furnace cavity is cleaned, the silicon-carbon heating rods and ceramic tubes need to be pulled out, and then the cover is lifted. Due to the brittle nature of the silicon-carbon heating rods and ceramics, operational damage to the silicon-carbon heating rods and ceramic tubes is inevitable during this process, resulting in unnecessary waste and increased production costs. Summary of the Invention

[0006] As an optimal technical solution of the present invention, supports are symmetrically arranged on one side of the insulation furnace body, a rotatable shaft is arranged between the two supports, one end of the insulation bag cover is fixed on the outer side of the shaft, and a tilting cylinder is arranged on one side of the insulation furnace body, and the telescopic rod of the tilting cylinder corresponds to the flange position of the insulation bag cover.

[0007] As a preferred technical solution of the present invention, there are two tilting cylinders, which are symmetrically arranged on both sides of the insulation furnace body.

[0008] As a preferred technical solution of the present invention, the maximum flip angle of the thermal insulation cover is 70°.

[0009] As a preferred technical solution of the present invention, an observation hole is provided on one side of the insulation furnace body.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the pneumatic flip cover structure of the aluminum liquid insulation furnace is reasonably designed and ingeniously conceived. By arranging the silicon-carbon heating rod and the ceramic tube in the insulation cover, the insulation cover can be lifted up by the flipping cylinder during maintenance, so that there is no need to pull out the silicon-carbon heating rod and the ceramic tube, avoiding unnecessary damage to the silicon-carbon rod and the ceramic tube during maintenance, reducing the probability of component damage, and effectively reducing production costs.
