The invention discloses a novel amalgamation barrel device. The novel amalgamation barrel device comprises a base; support legs are arranged under the base; motors are fixedly arranged on one sides ofthe support legs; a rotary separation device is arranged on the base, and comprises an outer rotating disc; an inner rotating disc is arranged in the outer rotating disc, and is connected with a transmission rod; guide rails are arranged on the inner rotating disc and the outer rotating disc, and are provided with rollers; the rollers are matched with the guide rails; a support rod is arranged between the rollers; rotating shafts are arranged at the two ends of the support rod, and are movably connected with the support rod and the rollers; the inner rotating disc and the outer rotating discare connected through the rollers; and the inner rotating disc drives an inner barrel, and an outer barrel is driven through the rollers, so that the outer barrel and the inner barrel are different inrotating speed to filter raw materials to achieve the effect of full filtration. The novel amalgamation barrel device has the beneficial effects of simple structure and convenience to use; and through different rotating speeds of the inner barrel and the outer barrel, the filtration and separation effect is achieved, and the filtration and separation effect is improved.
