As to technique scheme supplement and perfect, the present invention also comprises following technical characteristic.
The aperture width of getting described in described backflow through hole is positioned on the sidewall of soup room is obviously greater than height, becomes slit shape, expands the feed liquor scope of backflow through hole, to make to get when hydrops in soup room exceedes setting capacity can in time quick backflow to being incubated furnace chamber.
Described transmission system comprises a power transmission shaft vertically arranged, described impeller is arranged on this power transmission shaft, power transmission shaft arranges axial central through hole as described gas distribution channel, by this central through hole, inert gas is delivered directly to impeller place, while vane rotary, produce bubble in molten metal near impeller, auxiliary impeller breaks up neighbouring molten metal, plays better dispersion refining effect.
Described impeller is arranged at refining chamber near insulation smelting furnace side, the passway of described passage is positioned on the just right refining chamber bottom surface of impeller, the side away from insulation smelting furnace is located in the aperture that described transfusion through hole is positioned at refining chamber, extend the molten metal after impeller dispersion and be transported to the distance of getting soup room, play better refining and eliminate bubble.
Described transfusion through hole is positioned at the orifice position of refining chamber higher than described impeller upper surface.
The refining chamber sidewall of described transfusion through hole between the aperture of refining chamber and described insulation smelting furnace arranges the baffle plate protracted to refining chamber, plays better guide wire stream and froth breaking effect.
Two sides that described insulation smelting furnace is adjacent respectively arrange the refining chamber described in, two refining chamber are adjacent, and one fluid reservoir is set in adjacent side, all be communicated with described fluid reservoir by through hole bottom two refining chamber, when being incubated smelting furnace and refining chamber's maintenance, remaining molten metal can be stored into transfusion room.
The present invention by get soup room and insulation furnace chamber between partition wall on backflow through hole is set, following beneficial effect can be reached: 1, by molten metal reflux cycle, can remain that the molten metal temperature of getting in soup room reaches casting temperature requirement, reduce and get soup room and the temperature difference being incubated molten metal in smelting furnace, make to get soup room metal temperature to reach casting and require the molten metal temperature that prerequisite declines in low insulation smelting furnace, reduce energy consumption, reach energy-saving effect; 2, improve cast article qualification rate, reduce waste product and melt down, thus reduce energy consumption, reach energy-saving effect.
