Automatic device for realizing rapid reduction and drying treatment of livestock and poultry manure by utilizing black soldier flies and application of automatic device

Abstract

The present invention discloses an automatic device for realizing rapid reduction and drying treatment of livestock and poultry manure by utilizing black soldier flies and an application of the automatic device. The complete automatic device includes a manure and ingredient mixing and conveying unit, a material and black soldier fly larvae distribution unit, a manure stacked conveying and drying unit and a manure and worm vibration screening and reducing unit. The automation degree, modularization degree and spatial utilization ratio of the device disclosed by the present invention are high, and the rapid reduction and drying treatment of manure with high water content is accelerated according to the characteristics of saprophagous property, high water content tolerance and heating in activity of the black soldier fly larvae, so that not only may rapid and harmless treatment of manure in a livestock and poultry farm be solved, but also a high-quality organic fertilizer and a high-protein feedstuff may be obtained, and the manure may be truly changed into things of value and may become a new profit growth point of a breeding owner.

Description

technical field [0001] The invention belongs to the fields of agricultural resource utilization and ecological environment protection, and in particular relates to a complete set of automatic equipment for rapidly reducing and drying treatment of breeding manure by using black soldier flies and its application. Background technique [0002] With the increasing scale of livestock and poultry breeding, the degree of production intensification is getting higher and higher, and it is increasingly out of touch with the planting industry. There is not enough land for drying of livestock and poultry manure and feed residues within a certain time and space. Therefore, the unreasonable treatment of a large amount of manure has caused serious pollution to the atmosphere, soil and water environment. According to statistics, the discharge of livestock and poultry manure has become the primary source of pollution in agriculture. At present, the total annual discharge of livestock and poul...

AI Technical Summary

Problems solved by technology

[0005] Generally speaking, the above patents all involve the method of treating livestock and poultry manure by using the scavenging characteristics of black soldier fly larvae, but the technical methods provided are difficult to quickly solve the problem of drying a large number of high-humidity manure in farms

Generally speaking, the water content range with high fecal conversion efficiency for black soldier fly larvae is usually around 70%, but most types of livestock and poultry farms (such as pigs, cattle, ducks, etc.) 80%, or even close to 90% in some feeding stages (such as meat duck manure), the higher water content seriously restricts the efficiency of black soldier fly larvae transformation and utilization of manure

In addition, compared with the traditional manure treatment method, aerobic composting needs to add more auxiliary materials because the moisture content is controlled at about 60%. Although the anaerobic fermentation method can meet the harmless treatment requirements, the post-fermentation There are still hidden dangers in biogas slurry treatment
