The invention has the beneficial effects as follows: when copper-phosphorus brazing alloy is smelted, after the oxygen in confined reaction device and phosphorus reaction are complete, phosphorus will not reoxidize generation Vanadium Pentoxide in FLAKES, decrease the scaling loss of phosphorus, ensure that composition and the quality of copper-phosphorus brazing alloy; The flue dust produced in reaction process sinks under gravity, air pump aspirates the flue dust bottom reaction chamber, simultaneously smoke and dust purifier purifies flue dust, can by the Vanadium Pentoxide in FLAKES produced in smelting process whole cooled and solidified, non-environmental-pollution; And smoke and dust purifier can also purify for the impurity element such as iron, silicon, reduces the content of impurity, effectively improves the reaction efficiency in reaction chamber, facilitates the utilization ratio of reaction raw materials; The hot air circulate can also fallen after purification enters the recycling of confined reaction device.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described upper cover is provided with asbestos seal ring near described opening for feed place.
Adopt the beneficial effect of above-mentioned further scheme to be: asbestos seal ring can promote the stopping property of upper cover, strengthen
Further, described smoke and dust purifier is weld fumes refining plant.
The beneficial effect of above-mentioned further scheme is adopted to be: weld fumes refining plant can be effectively that Fe2O3, SiO2, MnO and HF adsorb to the harmful substances that mainly contains in flue dust.
