Device for preparing bio-organic fertilizer from biogas residue waste liquid based on straw

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, in particular to a device for preparing bio-organic fertilizer from straw-based biogas residue waste liquid. Background technique [0002] Organic fertilizer, commonly known as farmyard manure, consists of various animal and plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc., as well as cake fertilizers, mainly by means of supplying organic substances. It is a kind of fertilizer that can be mixed with each other in proportion or mixed with a small amount of soil for aerobic fermentation and decomposed to improve the physical and chemical properties of soil, promote plant growth and the circulation of soil ecosystem; [0003] There are also some technical solutions about the preparation of organic fertilizers in the prior art. For example, a Chinese patent with a bulletin number of CN 208087516U discloses a bio-...

Problems solved by technology

[0006] In order to make up for the shortcomings of the existing technology, the existing organic fertilizer preparation device is completed through conventional crushing and granulation. During the crushing and granulation process, it is easy to cause mechanical blockage, poor operation fluency, and affect the efficiency of preparation. , in the preparation process, due to the complex composition of materials, poor molding quality, and unenvironmental protection during the operation process, the present invention proposes a device for preparing bio-organic fertilizer based on straw biogas residue waste liquid
