Double-barrel protein separation device

The invention discloses a double-barrel protein separation device. The device comprises an outer barrel with a circular horizontal section, wherein a water inlet and a water outlet are respectively formed in the bottom and the upper part of the outer barrel; the water inlet is connected with a water pump; an inner barrel is arranged in the middle of the inner cavity of the outer barrel; the innerbarrel comprises a conical barrel and a circular barrel which are respectively arranged at the upper and lower parts; the conical barrel adopts a structure with an upper narrow part and a lower wide part; a plurality of granular filtering materials are mounted in a gap between the outer barrel and the inner barrel; and a backwashing opening is formed in one side of the circular barrel and on the side wall of the outer barrel. The device is simple in structure, can increase the filtering water flow area during normal filtering on the premise that the backwashing effect is guaranteed, and is good in filtering effect. 本发
