Description

Technical Field

[0001] The utility model relates to the technical field of black soldier fly insects, in particular to a fermentation tank for black soldier fly manure. Background Technique

[0002] The black soldier fly, a saprophagous insect of the family Stratiomyidae, can feed on livestock and poultry manure and domestic waste, and produce high-value animal protein feed. Due to its rapid reproduction, large biomass, wide food habits, high absorption and conversion rate, easy management, low feeding cost, good animal palatability and other characteristics, it is used for resource utilization. The manure of black soldier fly insects can be fermented and used as organic fertilizer, which has the effect of driving away house flies and various root pests, and can effectively reduce the use of pesticides and fertilizers. Usually, a fermentation tank for black soldier fly manure is used for operation.

[0003] However, the existing fermentation device still has the disadvantage of being inconvenient to separate the fermentation liquid from the fermentation residue. When the existing fermentation device discharges the fermentation liquid, the fermentation liquid is discharged together with the fermentation residue, and then the fermentation residue is screened out from the fermentation liquid, which improves the working efficiency and reduces the production volume. Therefore, a fermentation tank for black soldier fly manure is proposed.

[0004] A fermentation device using black soldier fly manure disclosed in the publication number CN217733077U. Although a fermentation device using black soldier fly manure includes four bases, the upper surfaces of the four bases are fixedly connected with a working box. A screening component is arranged inside the working box, a stirring mechanism is arranged inside the working box, a feeding pipe is arranged on the upper surface of the working box, and an air extraction pump is fixedly connected to the right side of the upper surface of the working box. The screening component includes a screw rod fixedly connected to the inside of the driven wheel. A moving block is threadedly connected to the outer surface of the screw rod, a limiting rod is slidably connected to the inside of the moving block, and a brush is fixedly connected to the upper surface of the moving block. With this fermentation device using black soldier fly manure, through the screening component, the fermentation liquid and the fermentation residue can be discharged separately. Compared with the traditional fermentation device, the fermentation liquid and the fermentation residue can be separated, avoiding the later-stage filtration of the fermentation liquid and the fermentation residue by the staff, increasing the workload and improving the production volume.

[0005] Although the above patent can discharge the fermentation liquid and the fermentation residue separately through the screening component, compared with the traditional fermentation device, the fermentation liquid and the fermentation residue can be separated, avoiding the later-stage filtration of the fermentation liquid and the fermentation residue by the staff, increasing the workload and improving the production volume. However, this device lacks the function of filtering harmful substances and removing odors from the discharged gas to ensure that the gas meets the atmospheric emission standards before being discharged to avoid environmental pollution.

[0006] Therefore, it is very necessary to invent a fermentation tank for black soldier fly manure to solve the above problems. Content of the Utility Model
