Double-discharging barrel of underpants-shaped lime bin of double-opening discharging type quantitative lime adding equipment

The underpants-shaped lime bin double-discharging barrel of the double-opening discharging type quantitative lime adding equipment is characterized in that the existing single-opening discharging type lime adding equipment is improved into the double-opening discharging type lime adding equipment, and the underpants-shaped lime bin double-discharging barrel is mainly innovated. Comprising a trouser waist cylinder, underpants cylinders, a crotch cylinder, trouser leg cylinders, trouser leg cylinders and a discharge hole flange, the underpants-shaped lime bin double-discharging barrel is connected with the lime bin, and the underpants-shaped lime bin double-discharging barrel is connected with the double-vibration discharging hopper; two sets of vibration discharging hoppers and quantitative feeding hoppers share one lime bin, quantitative feeding can be automatically conducted on two material mixing tanks of a filter press group at the same time, the structure is compact, the occupied area is small, and the li
