Description
Technical field
The present invention relates to noble metal detection technique field, in particular to a kind of controllable supplementary air type cupel(lation) furnaces.
Background technique
Assaying of firing method is not only the means of ancient enrichment gold and silver, and is the important means of gold and silver analysis；It is both domestic and external
Geology, mine, silver smelting factory all are widely used in producing using it as most reliable analysis method.Under the high temperature conditions, make
Solid reagent melts in crucible with mineral, rock or other products containing gold and silver, traps gold and silver, shape in the molten state with lead
It is separated at the metal sinking crucible bottom containing gold and silver etc. with slag, obtained metal is carried out ash at moderate temperatures and blow down lead
Gold and silver just can be obtained and close grain, then make separation of gold and silver that can find out the content of Jin Heyin with pyrogenic process or wet process；Ash is blown as assaying of firing method
The important means that noble metal is separated with lead in important step and lead (zinc, tin, iron, nickel) ensaying of analysis method, cupel(lation) furnace
It is critically important equipment in the analytical procedure that ash is blown.
The cupel(lation) furnace bought on the market can all automate heating, but still have presence in actual production
Many problems open fire door in the case where high-temperature heating, increase oxygen feeding amount, inherently have shadow to the product in cupel(lation) furnace
It rings；Fire door is opened in production and wastes much electricity, and for production cost and a kind of waste, and lead at high temperature can gas
Change volatilization, therefore will also result in the occupational disease of permanent heavy metal accumulation to the body of production operator, this is for personal phase
When harmful.
Presently, there are a kind of cupel(lation) furnaces to make fire door work by increasing air intake passage and air exhaust passage on burner hearth
When be able to maintain long-term closing, guarantee the safety of operator, while this kind of structure also makes the temperature in burner hearth more uniform, mentions
High whole working efficiency and work quality, but in use there are still shortcoming, cupel is put into burner hearth or
When being taken out out of burner hearth, cold wind is had from burner hearth open-mouth and is entered, in addition the wind that air intake passage and air exhaust passage are formed recycles, hold
It easily causes the air inlet in burner hearth chaotic, influences the temperature uniformity in burner hearth；When burner hearth is entered the wind by air intake passage, air inlet
Amount can not be adjusted, and may cause that air quantity is much in burner hearth or air quantity is too small, influence the metal disintegrate-quality in burner hearth, therefore having must
It is improved.
