Being mainly used in cupel(lation) furnace burner hearth, device is in burner hearth before rearward air outlet, and whole gas flow guiding assembly first half is positioned at stove
Rear portion in thorax, latter half of horn mouth embeds in the insulation material before air outlet slit, serves the effect front and back accepted.Bottom it to
The inclined-plane deflector that air duct direction tilts, the guiding hot-air that play the guiding role sinks to pressing close to cupel plate.After closing fire door
Form furnace air circulation passage, make to be placed on cupel and be enclosed with the shot surface of gold sample and can touch the oxygen of abundance, from
And complete to aoxidize ash and blow.Meanwhile, burner hearth and air outlet slit front portion are isolated into two regions by this gas flow guiding assembly, effectively hinder
In having stopped burner hearth, a large amount of of heat scatter and disappear, and temperature in keeping burner hearth has been played key effect.
The front end of described air inlet pipe is provided with inlet air flow adjustable valve；The end of escape pipe is provided with on-off control of giving vent to anger
Valve, inlet air flow adjustable valve and switching control pilot of giving vent to anger linker control system respectively.
Collection lead box it is provided with, it is simple to collect the Hydrocerussitum (Ceruse) condensed bottom described escape pipe.
Fire Assaying cupel(lation) furnace must be placed under strength exhaust hood.After closing fire door, empty in forming nearly two meters of long stoves
Air-flow circulation passage, the escape pipe being arranged on cupel(lation) furnace top defines certain air draft under exhaust hood strength pump drainage, whole
It individual air loop is from top to bottom negative pressure.Even without outside air draft, remain in whole air duct produce certain nature
Upwards draft, must pay attention to so regulating and controlling charge flow rate.
This utility model simple in construction, easy to use, reasonable in design, application flexibly, can be effectively improved ash and blow efficiency and effect
Really.Lead steam and lead oxide dust injury to human body are greatly decreased, protect environment, the performance improving Fire Assaying cupel(lation) furnace is risen
Arrive key effect.
