Preferably, frame is also provided with for walking on stage of overhauling.
According to the present invention, by screening plant, the dust in copper scrap material is removed, be this improves the quality of copper scrap, decreased the adverse effect that the smelting of dust impurities to copper scrap brings.
Accompanying drawing explanation
Fig. 1 is the side-looking structural representation according to drum screen for scrap copper of the present invention.
Fig. 2 looks closely structural representation according to drum screen for scrap copper of the present invention.
Detailed description of the invention
As depicted in figs. 1 and 2, Reference numeral 1 represents cylindrical shell, and Reference numeral 2 represents Left Drive device, Reference numeral 3 represents seal closure, Reference numeral 4 represents mainframe, and Reference numeral 5 represents riding wheel apparatus, and Reference numeral 6 represents right transmission device, Reference numeral 7 represents feed hopper, Reference numeral 8 represents feeder frame, and Reference numeral 9 represents walks on stage, and Reference numeral 10 represents catch wheel device, Reference numeral 11 represents embedded scraper transporter, and Reference numeral 12 represents discharge flapper.
According to one embodiment of present invention, provide and to useless recycled copper, can carry out for No. 2 useless recycled copper the drum sieve sieving process especially.
According to drum screen for scrap copper of the present invention, be made up of parts such as cylindrical shell 1, Left Drive portion 2, right driving section 6, seal closure portion 3, riding wheel apparatus 5, catch wheel device 10, embedded scraper transporters 11.
Copper scrap is added in the cylindrical shell 1 of drum sieve from feed hopper 7, and the speed that cylindrical shell 1 turns (preferred 10r/min) with 5-16 per minute rotates, and drive copper scrap to stir, copper scrap is kicked up upset, and mutually collides, and causes the dust impurities on copper scrap to be separated.
Because cylindrical shell 1 has the angle of inclination of 3 °-8 ° (preferably 5 °), copper scrap also moves forward while rotation, external from the other end expelling tube of cylindrical shell 1.
