The invention belongs to the technical field of
organic fertilizer preparation, and particularly relates to a device for preparing a bio-
organic fertilizer from
biogas residue waste
liquid based on
straw, the device comprises a circulation box, a feeding
pipe and a discharging
pipe, the upper end and the lower end of the side wall of the circulation box are connected with the feeding
pipe and the discharging pipe respectively, and a protective cover is fixed in the circulation box; the multiple scrapers are continuously matched for operation,
solid waste is arranged, the smoothness of the
solid waste in the conveying process can be improved, meanwhile, later forming operation is facilitated,
extrusion forming of the formed waste is achieved after the
solid waste is flatly laid and in the rolling process of the roller, integrated
machining operation can be achieved, transfer is reduced, and the production efficiency is improved. And meanwhile, the overall
processing fluency is improved, the
fertilizer processing efficiency is improved, stable forming of solid waste can be ensured when raw materials are insufficient or mechanical faults occur, so that the quality of the bio-
organic fertilizer is improved, meanwhile, when the raw materials are insufficient, an alarm can be given in time, shutdown can be conducted in time, energy is saved, and the environment is better protected.
