The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of feeding device of useless composition brass foam, comprise charging hopper, have the storage bin of inlet point and discharging opening and fixing brandreth, described charging hopper is located at the charge door place, top of storage bin, described discharging opening is positioned at the bottom of storage bin, described storage bin is fixed on the brandreth, it is characterized in that: described feeding device also comprises:
A plurality of air inlet pipes are laid in the upper, middle and lower and the bottom of storage bin, and the first group of air inlet pipe that wherein is positioned at the going up of storage bin, middle part is annular intake pipe, be to be surrounded on the storage bin inwall and to arrange, and offer a plurality of downward opening through holes on pipeline; Be positioned at second group of air inlet pipe of the bottom of storage bin, its pipeline in storage bin arranges down that along inwall the opening of pipeline is over against the discharging opening top; The 3rd group of air inlet pipe that is positioned at the bottom of storage bin directly is connected with the discharge nozzle of being located at discharging opening;
The other end of described discharge nozzle inserts in the interior melt of body of heater.
As improvement, described storage bin is coniform, and described first group of air inlet pipe is 2-3, respectively along on the storage bin, middle part inwall circumference is arranged in parallel, the through hole on the air inlet pipe pipeline is well-distributed 8-14 down of an opening.Can guarantee that like this air-flow is even in the storage bin, and aperture is not stopped up because of the whereabouts of copper foam.
As improvement, described second group of air inlet pipe is 2-3, and respectively along the conical inclined surface rectangular distribution of storage bin, and opening is provided with down.
As improvement, described a plurality of air inlet pipes are connected with the inlet pipe connection that is used to supply gas respectively, and are provided with the control gate valve in the junction.Can carry out the tolerance regulation and control according to the size of copper foam amount like this.
Improve again, be connected by flange between described charging hopper and the inlet point, and be provided with the valve of master cock.
At last, described discharge nozzle adopts double-coating, and internal layer is a gapless stainless steel tube, and skin is a refractory material, is provided with butterfly valve between the discharging opening of described storage bin and the discharge nozzle.
Compared with prior art, advantage of the present utility model is: all carry out automatically the osed top device from being fed to discharging, save the packing and the hand stock of useless composition brass foam, save time, laborsaving, dispersing when having avoided the copper foam reinforced simultaneously, and the flue gas of fusing generation; Upper, middle and lower and bottom at storage bin are provided with a plurality of air inlet pipes, and upward the air inlet pipe at middle part is to be provided with around the storage bin inwall, can carry out the tolerance regulation and control according to the size of copper foam amount simultaneously, make the copper foam be uniformly dispersed, and avoid precipitating producing, thereby increase operation rate; The copper foam enters directly through discharge nozzle that melt all melts in the stove (being to add copper under the liquid), makes the recovery rate of iron height, and is energy-conservation.Rational in infrastructure, the safety of operation of feeding device of the present utility model, practical, can increase work efficiency greatly and improve working environment.
