Abstract
The utility model relates to a waste hard alloy furnace reclaiming with zinc-fusion method, which comprises a furnace proper, a dust collector, a water liquid dust collector and a vacuum pump, wherein, the water liquid dust collector is connected respectively with the dust collector through a ''tee'', the dust collector is connected with the furnace proper through a corrugated pipe, the furnace inner lining is sequentially provided with a zinc collecting crucible, a transition crucible, a zinc melting crucible and a zinc extraction crucible from bottom to top, the zinc collecting crucible is arranged in a zinc transition chamber, the furnace proper is covered by a heat mantle; with an one-driving-two method adopted, the production period is shortened greatly; after one zinc extraction process is finished, the heating mantle is directly arranged on the other process for operation so the temperature increasing and decreasing processes are left out, and electric power is saved; a production period is shortened from 40-48 hours to 18-20 hours, the relative production output is increased from 50kgs to 100kgs, the electric power consumption is decreased by one third; zinc content is lowered below 0.02 percent, the operation becomes easier and more convenient.
Description
Technical field
The utility model relates to the molten method of a kind of zinc and reclaims the hard alloy scraps stove.
Background technology
As everyone knows, zinc and cobalt can form the zinc cobalt-base alloy at low temperatures, zinc is not had an effect with refractory carbide again, and the vapour pressure of zinc, cobalt differs greatly, the boiling point of zinc is 906 ℃, the boiling point of cobalt is 2900 ℃, and the vapour pressure of zinc is 2.46 normal atmosphere in the time of 1000 ℃, and the vapour pressure of cobalt is less than 1 mmhg.The molten method of zinc is exactly to utilize the cobalt in zinc and the Wimet to form low melting point zinc cobalt-base alloy, destroys the cohesive action of cobalt, with vacuum distillation method zinc is evaporated then, stays whole compositions of Wimet, becomes a kind of recovery method of loose spongy material.Having the molten method recovery of zinc hard alloy scraps stove now has two kinds, and a kind of is to go up to receive the zinc stove, and about every stove loading amount 50Kg, intensification, zinc melt, propose zinc, cooling, and 40～48 hours production cycles, main drawback is that production efficiency is low, and power consumption is big; Another kind is to receive down the zinc stove, and main drawback is that hard alloy scraps and zinc are contained in a plurality of crucibles to carry out zinc molten, and zinc is recovered in the crucible when carrying zinc, essential saw was thin when zinc re-used, operate pretty troublesome, the 2nd, the quality instability, contain zinc and exceed standard, this kind stove there be limited evidence currently of uses.
Summary of the invention
The purpose of this utility model just provides the molten method of a kind of zinc that overcomes defective in the prior art and reclaims the hard alloy scraps stove.
The technical solution of the utility model is by approach realization once.
The utility model contains body of heater, dust-precipitator, water liquid dust-precipitator and vacuum pump, wherein, water liquid dust-precipitator connects dust-precipitator respectively by three links, dust-precipitator is connected with body of heater by corrugated tube again, the inner bag of body of heater is disposed with from the bottom to top and receives the zinc crucible, excessively crucible, zinc melt crucible and carries the zinc crucible, and receive the zinc crucible and be positioned at that to take out zinc indoor, furnace body overcoat has heating mantles.
The utility model adopts traditional bell-type furnace, be designed to one drag two formula (shown in Figure 1), inner covers are overlapped in i.e. heating system configuration two, one be enclosed within intensification, melting, carry zinc, another set ofly then cool off, take on stove, this shortens the production cycle greatly, after a cover is carried zinc and is finished, heating mantles directly lifts to another set of going up and works, and saves cooling and heats up economize on electricity greatly.Make the production cycle foreshorten to 18～20 hours by 40～48 hours; Every furnace output is increased to 100Kg by 50Kg; Current consumption reduces by 1/3; Zinc content is guaranteed (standard is 0.02%) below 0.02%.Owing to designed four crucibles (as shown in Figure 2) in the stove, promptly received zinc crucible, transition crucible, the molten crucible of zinc, carry the zinc crucible.The molten crucible of zinc is used to adorn hard alloy scraps and zinc, and to carry out zinc molten; Receiving the zinc crucible is that the zinc that after zinc melts vacuum distilling is gone out is collected; Carry the zinc crucible zinc melt is carried zinc once more, guarantee the quality of reclaimed materials.Designing the purpose of the molten crucible of a zinc, is that the zinc of receiving the zinc crucible need not draw off and saw carefully, adds the direct zinc of hard alloy scraps and melts, and receipts zinc crucible originally becomes the molten crucible of zinc, and the molten crucible of zinc becomes receives the zinc crucible, more convenient to operate simple.

Wherein, body of heater 1, dust-precipitator 2, water liquid dust-precipitator 3, vacuum pump 4, corrugated tube 5, receive zinc crucible 6, excessively crucible 7, the molten crucible 8 of zinc, carry zinc crucible 9, heating mantles 10, take out zinc chamber 11, inner bag 12.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model contains body of heater 1, dust-precipitator 2, water liquid dust-precipitator 3 and vacuum pump 4, wherein, water liquid dust-precipitator 3 connects dust-precipitator 2 respectively by three links, dust-precipitator 2 is connected with body of heater 1 by corrugated tube 5 again, be disposed with from the bottom to top in the inner bag 12 of body of heater 1 and receive zinc crucible 6, excessive crucible 7, the molten crucible 8 of zinc and carry zinc crucible 9, and receipts zinc crucible 6 is positioned at takes out zinc chamber 11, the body of heater 1 outer heating mantles 10 that is with.
The utility model adopts traditional bell-type furnace, be designed to one drag two formula (shown in Figure 1), inner covers are overlapped in i.e. heating system configuration two, one be enclosed within intensification, melting, carry zinc, another set ofly then cool off, take on stove, this shortens the production cycle greatly, and after a cover was carried zinc and finished, heating mantles directly lift on another set of and works.Designed four crucibles (as shown in Figure 2) in the stove, promptly received zinc crucible, transition crucible, the molten crucible of zinc, carry the zinc crucible.The molten crucible of zinc is used to adorn hard alloy scraps and zinc, and to carry out zinc molten; Receiving the zinc crucible is that the zinc that after zinc melts vacuum distilling is gone out is collected; Carry the zinc crucible zinc melt is carried zinc once more, guarantee the quality of reclaimed materials.Designing the purpose of the molten crucible of a zinc, is that the zinc of receiving the zinc crucible need not draw off and saw carefully, adds the direct zinc of hard alloy scraps and melts, and receipts zinc crucible originally becomes the molten crucible of zinc, and the molten crucible of zinc becomes receives the zinc crucible, more convenient to operate simple.
With hard alloy scraps 100Kg, zinc 180Kg packs in the molten crucible 8 of zinc, is warming up to 800～850 ℃ during use, be incubated 8～10 hours and carry out zinc to melt; After zinc is molten temperature is risen to 880～900 ℃, vacuumize and carry zinc, the time is 8～10 hours; Then heating mantles 10 is winched on another inner cover and work on, this stove then carries out naturally cooling.
