[0001] This utility model relates to the field of bioconversion technology of organic waste, specifically a black soldier fly larvae-based kitchen waste treatment device. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of food waste generated is increasing year by year. Traditional waste disposal methods, such as landfill and incineration, not only occupy a large amount of land resources, but may also cause secondary pollution to the environment. In recent years, the use of insects to convert organic waste has become a green, environmentally friendly and sustainable emerging treatment method. Among them, black soldier flies can convert large amounts of food waste into valuable biological resources, such as insect protein and organic fertilizer, in a short period of time, thereby achieving the goal of waste resource utilization.

[0003] Existing black soldier fly larvae food waste treatment equipment on the market has certain limitations in its structural design. The main limitation is that the connection between the waste inlet and the hatching area is not smooth enough. This results in the food waste not being evenly distributed in the hatching area, affecting the feeding efficiency and growth rate of the black soldier fly larvae. Furthermore, this structural deficiency may also cause local waste accumulation, leading to problems such as odor emission and uneven humidity, which are not conducive to maintaining a healthy growth environment for black soldier flies and also increase the difficulty of equipment maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a black soldier fly food waste treatment device to solve the problems mentioned in the background art, such as uneven waste distribution, low feeding efficiency, and poor growth environment caused by poor connection between the waste inlet and the hatching area in current black soldier fly food waste treatment devices.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a black soldier fly food waste treatment device, including an incubation box 1. A feeding hopper 2 is located at the top center of the incubation box 1. A rectangular guide groove 3 is located on the rear inner wall of the incubation box 1. A drive block 4, which can move laterally, is symmetrically arranged inside the rectangular guide groove 3. A movable distribution plate 5 is rotatably connected to the outer side of the drive block 4. An internal suspended plate 7 is located at the bottom of the incubation box 1. The four corners of the bottom of the internal suspended plate 7 are connected to the bottom inner wall of the incubation box 1 through support columns 8. Dynamic ventilation mechanisms 6 are provided on both sides of the incubation box 1. The dynamic ventilation mechanism 6 includes a stepper motor 61, a swing arm 62, a ventilation pipe 63, and a conveying hose 64. With this structure, when food waste falls from the feeding hopper 2 into the incubation box 1, the drive block 4 can... By lateral displacement within the rectangular guide channel 3, the movable distribution plate 5 is driven to swing orderly inside the incubation chamber 1. The swinging of the movable distribution plate 5 disperses the kitchen waste, distributing it more evenly onto the internal support plate 7. The space formed between the internal support plate 7 and the bottom inner wall of the incubation chamber 1 via the support column 8 facilitates air circulation and humidity control, preventing direct contact between kitchen waste and the bottom of the incubation chamber 1, reducing the possibility of water accumulation, and preventing odor emission and bacterial growth caused by waste buildup. Simultaneously, the dynamic ventilation mechanism 6, through the coordinated operation of the stepper motor 61, swing rod 62, ventilation pipe 63, and conveying hose 64, provides fresh air more evenly to the interior of the incubation chamber 1, maintaining a suitable humidity and temperature environment. This device promotes the feeding efficiency and growth rate of black soldier fly larvae. Overall, it solves the problem of poor connection between the waste inlet and the hatching area in existing technologies, avoids the potential local accumulation of kitchen waste after entering the hatching chamber 1, reduces the risk of odor emission and uneven humidity, provides a healthier and more stable growth environment for black soldier flies, and improves the stability and efficiency of the entire treatment process. A servo motor 41 is bolted to the center of the drive block 4, and a rotating shaft 42 connected to the output shaft of the servo motor 41 is located on the outside of the drive block 4. A bearing is provided at the connection between the output shaft of the servo motor 41 and the rotating shaft 42. The top of the movable distribution plate 5 is fixedly sleeved on the outside of the rotating shaft 42. This structure... Servo motor 41 drives rotating shaft 42 to rotate, enabling movable distributing plate 5 to rotate synchronously with rotating shaft 42. This linkage mechanism ensures that movable distributing plate 5 can effectively swing, breaking up and evenly distributing the kitchen waste falling from feed hopper 2 into incubation box 1. Rectangular guide trough 3 has a transverse opening in the middle, and cylinders 9 are symmetrically fixed to the outer wall of the back side of incubation box 1 by support members. The output end of cylinder 9 extends to the transverse opening of rectangular guide trough 3 through a connector and is fixedly connected to the back side of drive block 4. When it is necessary to adjust the position of movable distributing plate 5 to break up and evenly distribute kitchen waste, the output end of cylinder 9 pushes or pulls drive block 4 to move precisely along rectangular guide trough 3, allowing movable distributing plate 5 to swing flexibly according to actual needs.Several ribs 51 are uniformly welded and fixed to the bottom end of the movable distribution plate 5, and the cross-section of each rib 51 is trapezoidal. These ribs 51 can swing synchronously with the movable distribution plate 5. Through physical cutting and stirring, the ribs 51 further disperse and evenly spread the waste, preventing material accumulation and ensuring uniform distribution of waste on the built-in overhead plate 7. The stepper motor 61 of the dynamic ventilation mechanism 6 is symmetrically fixed to both sides of the top of the incubation box 1 via a bracket. The ventilation pipe 63 is vertically installed on both sides inside the incubation box 1, with several air outlets evenly distributed on the outer side of the ventilation pipe 63. The two ends of the swing rod 62 are connected to the output shaft of the stepper motor 61 and the top of the ventilation pipe 63, respectively. Swing ports matching the structure of the swing rod 62 are opened on both sides of the incubation box 1. The conveying hose 64 is connected to the... The ventilation duct 63 runs through the middle of the back side and penetrates the side wall of the incubator 1. When the stepper motor 61 starts, this structure drives the swing arm 62 to rotate around its output shaft. The rotation of the swing arm 62 causes the ventilation duct 63 to swing at a certain amplitude. Simultaneously, the swing openings on both sides of the incubator 1 ensure the smooth movement of the swing arm 62. The outer end of the delivery hose 64 can be connected to a gas supply device to uniformly provide fresh air to the interior of the incubator 1. Several circular filters 71 are evenly embedded in the built-in overhead plate 7, and the gaps between the circular filters 71 are provided with strip-shaped guide channels 72 with arc-shaped inner walls. This structure of the circular filters 71 effectively filters out larger solid particles, ensuring that only materials of suitable size pass through, while the strip-shaped guide channels 72 help guide the smooth flow of liquids and fine particles, avoiding blockages.

[0019] Working Principle: When using this black soldier fly larvae to process kitchen waste, firstly, when the kitchen waste falls from the feed hopper 2 into the incubation chamber 1, the output end of the cylinder 9 pushes or pulls the drive block 4 along the rectangular guide groove 3 for precise lateral movement via the connector. At the same time, the servo motor 41 drives the rotating shaft 42 to rotate, causing the movable dispersing plate 5 to swing. Thus, as the drive block 4 moves and the movable dispersing plate 5 swings synchronously, the movable dispersing plate 5 can effectively disperse the kitchen waste, and the rib plate 51 can further disperse and evenly spread the waste. Meanwhile, when the stepper motor 61 of the dynamic ventilation mechanism 6 starts, its output shaft drives the swing rod 62 to rotate, causing the ventilation pipe 63 to swing at a certain amplitude. The gas supply equipment connected to the conveying hose 64 delivers air to provide fresh air to the incubation chamber 1, maintaining a suitable humidity and temperature environment. When the kitchen waste falls onto the built-in overhead plate 7, several circular filters 71 can effectively filter out larger solid particles, while the strip-shaped guide groove 72 can guide the smooth flow of liquid and fine particles, thereby completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
