Technical Field

[0001] The utility model relates to the technical field of exhaust hoods, in particular to a movable anti-corrosion exhaust hood. Background Art

[0002] During the automated precious metal ingot casting process, the precious metal mixture is heated and melted into liquid, which will emit a large amount of toxic high-temperature flue gas containing weak acid. Usually, a set of anti-corrosion exhaust hoods (made of anti-corrosion titanium alloy or 316 stainless steel) is installed at the exhaust port above the precious metal ingot casting equipment to collect the exhaust gas and discharge it into the exhaust duct.

[0003] However, in the prior art, when using the anti-corrosion exhaust hood of precious metal ingot casting equipment, it is found that the exhaust hood is generally fixedly arranged above the ingot casting equipment. However, since the feeding position is also located above the ingot casting equipment, it will affect the feeding equipment and it is not convenient to add materials from the ingot casting equipment to the ingot casting equipment. Secondly, the anti-corrosion exhaust hood of the precious metal ingot casting equipment cannot be adjusted according to the distance from the feeding and exhaust port to absorb the smoke.

[0004] Therefore, a movable anti-corrosion exhaust hood is proposed to solve the above problems. Utility Model Content

[0012] As a preferred embodiment, four of the eight rollers form a group, and the surfaces of two groups of rollers are movably embedded in the two hanging rails, and the surface of one side of the gear is meshedly connected to the surface of the rack.

[0013] As a preferred embodiment, the tops of the four electric telescopic rods are fixedly connected to the bottom of the mobile box, and the surfaces of the two top ends of the telescopic hoses are fixedly embedded in the inside of the other end of the exhaust slot.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. The utility model connects one end of the telescopic hose to an industrial smoke extractor, and then connects the device to an external power supply device, which provides power to an automatic control box, a bidirectional motor and an electric telescopic rod.
