Abstract
The utility model discloses a smelting device for copper-phosphorus brazing filler metal, which comprises a closed reaction unit and a fume purification device, wherein the closed reaction unit is provided with a feeding port, and the fume purification device is communicated with an inner cavity of the closed reaction unit through a fume exhaust pipeline. A lining layer is arranged on the inner surface of the closed reaction unit, an intermediate frequency induction coil is arranged in the closed reaction unit, a reaction crucible is arranged in the intermediate frequency induction coil, an upper cover is movably arranged on the feeding port, the fume purification device is a water pool, and the fume exhaust pipeline is arranged deeply in the water pool. The smelting device for the copper-phosphorus brazing filler metal has the advantages that when the copper-phosphorus brazing filler metal is smelted, phosphorus is not oxidized any more after complete reaction of oxygen and phosphorus in the reaction unit so that burning loss of the phosphorus is decreased, phosphorus pentoxide which is generated during smelting can be completely dissolved in water by the aid of the fume purification device, and generated phosphoric acid byproducts can be used for cleaning the copper-phosphorus brazing filler metal. The smelting device for the copper-phosphorus brazing filler metal belongs to short-process smelting devices, decreases energy and resource consumption brought by secondary smelting and is environment-friendly and energy-saving.
Description
Technical field
The utility model relates to smelting device, especially relates to the smelting device of the copper-phosphorus brazing alloy that a kind of welding field uses.
Background technology
Copper phosphorus series solder has the advantage of intensity height, good manufacturability as self-drill brazing filler, is widely used in household electrical appliance industries such as refrigerator, air-conditioning.Copper-phosphorus brazing alloy is in smelting process; When phosphorus adds fashionablely with simple substance form, be prone to generate a large amount of Vanadium Pentoxide in FLAKESs with airborne oxygen reaction, the Vanadium Pentoxide in FLAKES smog emission of generation can cause environmental pollution in air; Harm humans is healthy; And, make the composition of copper-phosphorus brazing alloy, quality be difficult to control because a large amount of oxidations of phosphorus are burnt seriously.The copper-phosphorus brazing alloy smelting technology adopts the secondary smelting mode to prepare the copper-phosphorus brazing alloy ingot mostly at present; That is: when copper-phosphorus brazing alloy was smelted, phosphoric added with the mode of high phosphorus copper phosphorus master alloy, and this smelting mode need be refined high phosphorus copper phosphorus master alloy in advance; Not only time-consuming taking a lot of work; Because impurity contents such as iron, silicon are too high, carry out copper-phosphorus brazing alloy when preparing as starting material in the high phosphorus copper phosphorus master alloy of preparing, can have a strong impact on the quality of copper-phosphorus brazing alloy with it; Still can generate a large amount of Vanadium Pentoxide in FLAKES smog in the smelting process simultaneously, cause environmental pollution; On the other hand, the energy that secondary smelting is brought and resource consumption do not meet energy conservation and environment protection again.
Summary of the invention
The purpose of the utility model be to provide a kind of pollution-free, the phosphorus scaling loss is few and the smelting device of the copper-phosphorus brazing alloy that can accomplish through melting once.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The smelting device of the described copper-phosphorus brazing alloy of the utility model, it comprises confined reaction device that has opening for feed and the smoke and dust purifier that passes through smoke discharging pipe and confined reaction device intracavity inter-connection; The internal surface of said confined reaction device is provided with the refractory heat-insulating air retaining wall, in said confined reaction device set inside the Medium frequency induction circle is arranged, and is placed with reaction crucible in the said Medium frequency induction circle, and said opening for feed is provided with loam cake; Described smoke and dust purifier is the pond, and said smoke discharging pipe gos deep in the suction sump.
Distance between said Medium frequency induction circle and the confined reaction device sidewall is greater than 250mm.
The said loam cake that fits with the confined reaction device is provided with asbestos seal ring.
The advantage applies of the utility model exists:
When 1, copper-phosphorus brazing alloy is smelted, after oxygen in the confined reaction device and phosphorus reaction are complete, phosphorus will not reoxidize the generation Vanadium Pentoxide in FLAKES, reduce the scaling loss of phosphorus, guarantee the composition and the quality of copper-phosphorus brazing alloy; Smoke and dust purifier can all be dissolved in the water the Vanadium Pentoxide in FLAKES that produces in the smelting process non-environmental-pollution simultaneously.
2, the be dissolved in the water phosphoric acid sub product that forms of Vanadium Pentoxide in FLAKES can be used for the cleaning of copper-phosphorus brazing alloy, and resource is fully used.
3, but the primary smelting of this device becomes the copper-phosphorus brazing alloy alloy, belongs to short flow process smelting device, has reduced the energy and resource consumption that secondary smelting is brought, has the environmental protection and energy saving meaning.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the smelting device of the described copper-phosphorus brazing alloy of the utility model, it comprises confined reaction device 1 that has opening for feed and the smoke and dust purifier that passes through smoke discharging pipe 2 and confined reaction device intracavity inter-connection; The internal surface of confined reaction device 1 is provided with refractory heat-insulating air retaining wall 3, in confined reaction device set inside Medium frequency induction circle 4 is arranged, and the distance between Medium frequency induction circle 4 and confined reaction device 1 sidewall is greater than 250mm; In Medium frequency induction circle 4, be placed with the desirable reaction plumbago crucible 5 that changes, need crucible be fixed after each the placement; Opening for feed is provided with loam cake 6, suit asbestos seal ring 8 on the loam cake 6, and loam cake 6 will keep flexible unlatching, to shorten the opening time; Smoke and dust purifier is pond 7, and smoke discharging pipe 2 gos deep in the suction sump 7.
During smelting, water filling in pond 7 guarantees that smoke discharging pipe 2 gos deep into the water surface below 1 meter; Putting into red phosphorus in the reaction plumbago crucible 5 in confined reaction device 1, is copper alloy liquid with meltings such as raw copper, silver in the smelting copper alloy stove, rapidly copper alloy liquid is skimmed then and pours in the reaction plumbago crucible 5; Cover loam cake 6 fast; 4 energisings of Medium frequency induction circle, the alloy in the heating crucible 5 is until complete alloying; The solder alloy liquid that then reaction is obtained in mould, is prepared into the copper-phosphorus alloy ingot around the stationary shaft rotary casting.Reaction process is in sealed state fully, and entire reaction course is no more than 15 minutes, and the Vanadium Pentoxide in FLAKES that generates in the reaction directly is dissolved in the water through smoke discharging pipe 2.After the oxygen in the confined reaction device reacts completely, phosphorus will be not the regeneration Vanadium Pentoxide in FLAKES, so the phosphorus scaling loss is seldom in the whole process.
