Full-automatic organic fertilizer feeding and distribution device and control method

Abstract

The invention relates to a full-automatic organic fertilizer feeding and distribution device, which comprises a feeding apparatus, a distribution apparatus, a fermentation tank and a central controller. The feeding apparatus is mainly composed of biogas residue bins, an auxiliary material bin, a material returning bin, an inoculant bin, spiral conveyors and a belt conveyor. The biogas residue bins, the auxiliary material bin, the inoculant bin and the material returning bin are all provided with weighing equipment, the bottoms of the biogas residue bins, the auxiliary material bin, the inoculant bin and the material returning bin are all equipped with the spiral conveyors, which are connected to the belt conveyor. The belt conveyor is connected to the distribution apparatus, and the distribution apparatus is mainly composed of a telescopic belt conveyor, an upper frame beam, a forward and reverse rotation belt conveyor and a lower frame beam. The upper frame beam and the lower frame beam form a double-layer cross-shaped frame beam structure; and the telescopic belt conveyor is arranged in the upper frame beam. The invention has the beneficial effects that: control signals of the feeding apparatus, the distribution apparatus and other equipment are accessed into a control system, thus realizing automatic feeding and distribution of all materials.

Description

technical field [0001] The patent relates to a fully automatic organic fertilizer feeding and distributing device and a control method, belonging to the technical field of preparing organic fertilizer from biogas engineering biogas residue. Background technique [0002] After anaerobic fermentation and solid-liquid separation of organic waste, a large amount of biogas residue is produced. Except for methane, carbon dioxide, water-soluble ammonia and other components, other nutrients are basically retained in the biogas residue. Therefore, biogas residue contains more comprehensive nutrients and is an excellent raw material for the preparation of organic fertilizers. But at the same time, biogas residue has the characteristics of high moisture content, low carbon-nitrogen ratio, and contains a large amount of colloidal substances with certain viscosity, which makes the preparation of organic fertilizers a certain challenge. [0003] At present, in the technical field of prep...

AI Technical Summary

Problems solved by technology

Since the moisture content of the raw materials drops below 65% after mixing, the fluidity is poor, and manual or semi-automatic feeding and distributing methods are used to easily cause uneven distribution of organic fertilizers; under the action of turning machines and aeration systems, large-scale The degree of organic fertilizer fermentation in the biogas residue fermentation tank is not uniform, some organic fertilizers are incompletely fermented, and some organic fertilizers are excessively fermented, resulting in the loss of nutrients

When the situation is more serious, it will lead to the deterioration of the aerobic fermentation environment, and eventually lead to the failure of organic fertilizer preparation
