Description

Anaerobic circular fermentation mechanism

Technical Field

The utility model relates to a fermentation equipment of material, in particular to circular fermentation mechanism of anaerobism belongs to fermentation auxiliary engine technical field.

Background

The existing anaerobic soybean meal fermentation mainly has the following forms: material pile type fermentation, rectangular bed type fermentation, box type fermentation, rotating disc type fermentation and cylinder rotating arm fermentation machines.

The material pile type fermentation has no structure, so that the material pile is random, the yield is low, the continuous production can not be realized, and the fermentation condition is difficult to control, thereby causing the uneven fermentation quality.

The bed of material of rectangle bed formula fermentation is difficult to do the height, adopts the mode ejection of compact auger to ejection of compact, and the auger buries in the material below, and the material that has fermented is very glutinous, even the below material is drawn empty, and the inside adhesion stress of material self is fine, and the material of auger top can not fall into the auger in many times, consequently can't discharge smoothly, and consequently the bed of material can not be very high. In addition, the fermentation bed is long in length and large in area, and surface materials are not isolated from air, so that the anaerobic effect is not good, and the fermentation quality is not good compared with bottom materials.

The single box of box fermentation is small, and the material is piled and is fermented in the box, and the mode that the box upset can only be passed through to quick ejection of compact, therefore the box is inconvenient to be done greatly, and output is low, and the transport of making a round trip is wasted time and energy, and difficult clearance is difficult to accomplish serialization production hardly.

The rotating disc type fermentation adopts a disc rotating mode, materials are stacked on a disc, the disc needs to carry the animal materials to rotate together during material distribution and material discharge, and the load is large and the energy consumption is large. For the anaerobic fermentation working condition, the higher the material is piled up, the better the fermentation effect is, and the tray rotating mode load is just bigger, and the material above can not completely cut off the air in addition, and the anaerobic condition can not be controlled, and the fermentation effect is relatively poor.

The cylindrical rotating arm fermentation machine comprises a circular tower body, a circular fermentation bed is arranged at the lower part of the circular tower body, a central cylinder body extending upwards is arranged at the center of the circular fermentation bed, a rotary large arm extending horizontally along the radial direction is installed at the top of the central cylinder body, the outer end of the rotary large arm is supported at the upper port of the circular tower body through a traveling driving mechanism, a lifting mechanism is installed on one side of the rotary large arm, a feeding and discharging auger is arranged at the lower end of the lifting mechanism, and a material sensing device is arranged on the outer side of the feeding and discharging auger.

During material distribution, the material from the central material pipe falls into the central area of the round fermentation bed through the inclined chute and is gradually accumulated; when the materials are stacked to the height of the feeding and discharging packing auger, the feeding and discharging packing auger rotates forwards to convey the materials from the central area to the peripheral area. When the material sensing device outside the feeding and discharging auger detects a material signal, the traveling driving mechanism drives the rotary big arm to revolve around the axis of the circular tower body. And after the material signal of the material sensing device disappears, the rotary big arm stops revolution, and the revolution is repeated, so that the materials are uniformly paved on the circular fermentation bed. The lifting mechanism can drive the feeding and discharging auger to lift so as to change the height of the material layer. When the fermentation is finished and the material is discharged, the feeding and discharging auger reversely rotates to convey the material from the peripheral area to the inside of the central cylinder and flow out from the lower end of the central cylinder. The lifting mechanism can drive the feeding and discharging auger to descend layer by layer until the materials on the round fermentation bed are completely discharged.
