The charcoal-isolated drum sieve comprises a drum sieve screen and a drum frame supporting the drum sieve screen. The inner wall of the left end of the drum frame is connected with a pipe, a bearing penetrates into the pipe, the bearing, the pipe and an axis of the drum frame are superposed, one ends of the bearing and the pipe extend out of an adsorption groove, and a sealing device is arranged at a contact position of the pipe and the adsorption groove. Since the drum sieve of the charcoal-isolated drum sieve can rotate, open area of the ore pulp on a charcoal-isolated sieve is improved by three times as compared with that of an original fixed type drum sieve, utilization of the sieve screen is up to 100%, the service life of the sieve screen is prolonged by one time as compared with that of the original fixed type drum sieve, and the sieve screen can be replaced flexibly and conveniently. Further, activated charcoals blocking screen meshes can be scoured by the ore pulp along with rotation of the drum sieve, and the problem of blockage of the sieve screen is solved. By the aid of the sealing device, loss of gold between grooves is avoided and economic loss is reduced.
