A kind of insulation smelting device

Technical field

The present invention relates to technical field of soldering materials, particularly one insulation smelting device.

Background technology

The smelting process of high phosphor copper alloy the most general at present first prepares two plumbago crucibles, and a crucible dries thoroughly and cools, and is put into by phosphorus wherein; Another crucible puts electrolytic copper, and be heated to 1200 ~ 1250 DEG C and form copper solutions, poured into by copper liquid in last crucible, jog crucible 5 ~ 10min promotes reaction, and uncap, stirs evenly alloy solution, cast of skimming; This method when melting high phosphor copper alloy, because phosphorus content is higher, phosphorus in copper solutions rapid flotation to surface and contact with air, cause a large amount of phosphorus to become P in the reaction ₂o ₅gaseous volatilization, not only contaminate environment, cause a large amount of losses of phosphorus raw material; In addition, if add violent boiling, the splashing that copper solutions must cause copper solutions in the crucible directly to loading phosphorus, the personnel safety of operator is jeopardized; Prior art heat-insulating property is not strong, and energy waste is large.

Summary of the invention

Technical problem to be solved by this invention is to provide the insulation smelting device that a kind of bilayer carries out being incubated, heat-insulating property is strong, can reduce energy consumption, promote efficiency.

The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of insulation smelting device, comprise closed unit, crucible, heating unit, Venturi tube and tank, described crucible is placed in described closed unit, the upper end of described crucible is provided with dismountable sealing cover, described heating unit is around described crucible, the exit end of described Venturi tube stretches into the bottom in described crucible through described sealing cover, the entrance end of described Venturi tube passes described closed unit and passes through pipeline communication with nitrogen delivery conduit and Yellow Phosphorus Tanks respectively, the pipeline that described nitrogen delivery conduit and Yellow Phosphorus Tanks are communicated with the entrance end of described Venturi tube is respectively arranged with the first magnetic valve and the second magnetic valve, described tank is placed in the side of described closed unit, and the upper end of described crucible is drawn vapor pipe and passed the bottom that described closed unit stretches into described tank, the inner side of described closed unit is provided with the first thermal insulation layer around its inwall, and the outer ring of described closed unit is provided with the second thermal insulation layer around its outer wall.

The invention has the beneficial effects as follows: the first thermal insulation layer and the second thermal insulation layer bilayer are incubated housing, promote heat insulation effect, reduce the energy consumption of heating unit, promote efficiency.

On the basis of technique scheme, the present invention can also do following improvement.

Further, the outside of described Venturi tube is coated with incubation cavity, and described incubation cavity is communicated with by through hole with inside described closed unit.

The beneficial effect of above-mentioned further scheme is adopted to be: to freeze when incubation cavity can prevent phosphorus solution from being sucked Venturi tube by nitrogen.

Further, described first thermal insulation layer is made up of slag wool, and described second thermal insulation layer is made up of silicon rubber foam material.

Adopt the beneficial effect of above-mentioned further scheme to be: slag wool and silicon rubber foam material good effect of heat insulation, skin can touch silicon rubber foam material by hand, promotes security.
