Description

Technical Field

[0001] This application belongs to the field of black soldier fly farming technology, specifically a black soldier fly farming device based on the separation of solid residue from kitchen waste. Background Technology

[0002] Black soldier fly farming is an activity with both ecological and economic value. First, a suitable breeding site must be prepared, such as a well-ventilated indoor space with suitable lighting or a specially built breeding shed. Breeding containers can be plastic boxes, wooden crates, etc. As for feed, black soldier fly larvae feed on organic waste such as kitchen waste and livestock manure. These feeds need to be pre-treated, such as crushing and fermenting, to facilitate larval feeding and growth. Black soldier flies have a strong reproductive capacity. After mating, adults will lay eggs in a suitable place. After the eggs hatch, they become larvae. After several instars of growth and development, the larvae will pupate, and the pupae will then emerge as adults, and so on.

[0003] For example, the utility model patent with announcement number CN220479702U discloses a kitchen waste solid slag conversion device based on a black soldier fly breeding system. It includes a main body, a crushing box, an oil extraction box, a three-phase separator, and a breeding box. The top surface of the main body is fixedly connected to a feed inlet. The crushing box, oil extraction box, and three-phase separator are arranged vertically inside the main body. By setting the crushing box, oil extraction box, and three-phase separator arranged vertically inside the main body, and the breeding box set at the bottom of the main body, all the structures that need to be connected after the kitchen waste is crushed adopt an integrated mechanism, which can avoid leakage during the conveying process, prevent the spread of odor from leaked waste residue and liquid, reduce environmental pollution, and reduce the footprint of the entire equipment, which is conducive to the placement of the equipment.

[0004] However, during actual use, it was discovered that the device directly discharged the solid residue of the crushed and separated kitchen waste into the breeding box to feed black soldier flies.

[0005] However, the solid residue of kitchen waste contains large molecules that are difficult for black soldier flies to digest and absorb, affecting its palatability and larval feeding efficiency. In addition, the solid residue can carry pathogens and parasite eggs, which can easily breed and spread in the breeding box, causing black soldier flies to get sick and thus reducing breeding efficiency. Therefore, a black soldier fly breeding device based on the separation of solid residue from kitchen waste is provided. Utility Model Content

The circular mesh cylinder 6 is provided to facilitate the forward movement of the crushed solid slag inside it, while the liquid inside the solid slag is located inside the conveying shell 3, thereby achieving solid-liquid separation.

[0024] refer to Figure 1 , Figure 2 and Figure 3 A drain pipe 8 is fixedly installed at one end of the conveying housing 3 and is connected to an external liquid collection tank. The drain pipe 8 facilitates the discharge of liquid from the inside of the conveying housing 3 for subsequent processing.

[0025] refer to Figure 1 , Figure 3 The solid slag conveying mechanism 7 includes a rotating shaft 701, a spiral conveying blade 702, and a motor 703.

The crushing rollers are connected to the rotating shaft 701 through a pulley, so that the rotating shaft 701 can drive the crushing rollers to rotate together when it rotates, which facilitates the crushing treatment of kitchen waste.

[0027] refer to Figure 1 , Figure 3 and Figure 4 The fermentation treatment component 5 includes an inner fermentation shell 501, a connecting pipe 502, a stirring shaft 503, a motor 504, a liquid distribution plate 505, a drain hole 506, and a connecting guide pipe 507.

The discharge pipe allows personnel to open the electrically controlled valve to allow the fermented solid residue inside the inner fermentation shell 501 to enter the interior of the breeding box 1 for feeding black soldier flies. The connecting pipe 502 facilitates the entry of the kitchen waste solid residue after solid-liquid separation into the interior of the inner fermentation shell 501.

[0028] refer to Figure 1 , Figure 3 and Figure 4 A liquid distribution plate 505 is fixedly installed on the top surface of the inner fermentation shell 501.

A temperature sensor 12 is fixedly installed on the top surface of the processing tank 2, with the monitoring end of the temperature sensor 12 extending into the interior of the processing tank 2. The liquid inlet pipe 9 facilitates the introduction of external liquid into the interlayer between the processing tank 2 and the inner fermentation shell 501. The liquid is then heated by the motor heat pipe 11, and with the monitoring of the temperature sensor 12, the liquid temperature is controlled within a suitable range. This facilitates the decomposition of additives and thorough mixing of solid residue, thereby improving the fermentation efficiency of solid residue.

[0031] The implementation principle of the black soldier fly breeding device based on the separation of solid residue from kitchen waste in this application is as follows: The user first pours the kitchen waste into the crushing box 4. The crushing roller in the crushing box 4 will crush the kitchen waste. The crushed small pieces of kitchen waste enter the circular mesh cylinder 6. In the circular mesh cylinder 6, the solid residue formed by the small pieces of kitchen waste moves forward continuously under the push of the spiral conveying blades 702. During this process, the liquid in the solid residue flows into the conveying shell 3 through the mesh holes on the circular mesh cylinder 6 and is discharged through the drain pipe 8, while the solid residue continues to move forward and enters the inner fermentation shell 501 through the connecting pipe 502.

[0032] At this time, the operator starts the motor heat pipe 11 to heat the liquid in the interlayer between the processing tank 2 and the inner fermentation shell 501, thereby maintaining the internal temperature of the inner fermentation shell 501 within a suitable range. Subsequently, the operator starts the external liquid supply pump to deliver an appropriate amount of microbial agents and other additives for solid residue fermentation to the connecting liquid guide pipe 507. The additives are discharged through the drain hole 506 at the bottom of the liquid distribution plate 505 and mixed with the solid residue in the inner fermentation shell 501. At the same time, the motor 504 drives the stirring shaft 503 to rotate, so that the microbial agents and solid residue are fully mixed, effectively improving the fermentation process. The fermentation efficiency of the solid residue is such that the fermented residue is fed into the breeding tank 1 through the discharge pipe for breeding black soldier flies. This device can effectively ferment the solid residue, and the fermentation process can effectively remove bacteria and parasite eggs from the residue, reducing the possibility of bacteria and parasite eggs breeding and spreading in the breeding tank, reducing the risk of disease in black soldier flies, and creating a healthier living environment for black soldier flies. On the other hand, fermentation changes the physical and chemical properties of the solid residue, making it more palatable, which can increase the feeding enthusiasm of black soldier flies, promote their growth and development, and thus improve the breeding quality and yield of black soldier flies.
