Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-5 This embodiment provides a black soldier fly drying device, including a scraping and limiting input mechanism 100, a stacked drying chamber mechanism 200, a dual-air-outlet circulating heat exchange mechanism 500, and a limiting output mechanism 300. The stacked drying chamber mechanism 200 includes multiple layers of staggered conveyor network groups, each conveyor network group including at least alternating vertically arranged left conveyor network 201 and right conveyor network 202; the starting ends of the conveyor networks are arranged in vertically aligned front and back, and each end is provided with a material conversion interface 203; wherein, at least one layer of conveyor network extends from the starting end to provide a feeding connection structure 211, and at least one layer of conveyor network extends from the end to provide a discharging connection structure 212, the feeding connection structure 211 docks with the scraping and limiting input mechanism 100, and the discharging connection structure 212 docks with the limiting output mechanism 300; specifically, the left and right conveyor networks 202 are arranged vertically alternately, and are connected through the conversion interface 203 to form a continuous "zigzag" material trajectory, forming a multi-layer high-capacity drying chamber.

[0023] The aforementioned left conveyor network 201 is respectively set on the top and bottom of the stacked drying chamber mechanism 200; its feeding connection structure 211 is set on the starting end of the top left conveyor network 201 and docks with the scraping and limiting input mechanism 100; its discharging connection structure 212 is set on the end of the bottom left conveyor network 201 and docks with the limiting output mechanism 300; wherein the feeding connection structure 211 and the discharging connection structure 212 are mainly used for seamless docking of the target product tray on the scraping and limiting input mechanism 100 into the stacked drying chamber mechanism 200. The stacked drying chamber achieves a zigzag conveying and drying path of materials through the alternating vertical arrangement of the left and right conveyor networks 202 of the multi-layer staggered conveyor network group, and then the target product tray dried by the stacked drying chamber mechanism 200 is conveyed out to the feeding end 301 of the limiting output mechanism 300.

[0024] It should be noted that the alternating vertically arranged left and right conveyor networks are controlled by two independent rotating shafts. One rotating shaft controls all the left conveyor networks 201 within the stacked drying chamber mechanism 200, while the other rotating shaft controls all the right conveyor networks 202 within the stacked drying chamber mechanism 200. This achieves consistency, flexibility, and reliability in the multi-layer conveyor system, enabling the stacked drying chamber mechanism 200 to meet the high efficiency requirements of large-scale production.

[0025] The leveling and limiting input mechanism 100 includes a scraper, a first conveyor network, and a first limiting plate set at a preset distance on the first conveyor network. The scraper is located on the output end 101 of the leveling and limiting input mechanism 100 and is positioned above the first conveyor network. The first limiting plate on the first conveyor network is used to control the spacing of the target product tray during transport and to prevent the target product tray from moving when it is being transported upwards. The scraper is mainly used to level the black soldier fly larvae in the target product tray before it is fed into the stacked drying chamber mechanism 200, so that the black soldier fly larvae are evenly spread out and the larvae are dried evenly.

[0026] The dual-outlet circulating heat exchange mechanism 500 includes a heat exchanger 501, a blower duct 502, and a waste heat recovery unit 503. The hot air distribution port of the dual-outlet circulating heat exchange mechanism 500 is located on the output port of the blower duct 502. The input port of the blower duct 502 consists of a first air inlet and a second air inlet. The first air inlet is connected to the outlet of the heat exchanger 501. The hot air distribution port is located in the middle of one side of the stacked drying chamber mechanism 200 and is adapted to the interlayer gap of all conveyor networks in the stacked drying chamber mechanism 200. The recovery port of the waste heat recovery unit 503 is connected to the stacked drying chamber mechanism 200, and the output port is connected to the second air inlet. Specifically, the first air inlet is connected to the heat exchanger 501 to introduce high-temperature hot air, and the second air inlet is connected to the waste heat recovery unit 503 to receive the treated circulating hot air. The hot air distribution port is adapted to the gap between the conveyor belts in the stacked drying chamber, which can penetrate the material layer laterally to achieve uniform drying. At the same time, the waste heat recovery unit 503 recovers the heat of the humid air in the drying chamber, which is mixed with the fresh hot air through the second air inlet and recycled to form a closed-loop system, which has both high-efficiency drying and energy-saving characteristics.

[0027] In this embodiment, a vibration mechanism 400 is also included, with a limiting output mechanism 300 located between the stacked drying chamber mechanism 200 and the vibration mechanism 400. The inlet end 301 of the limiting output mechanism 300 is connected to the outlet connection structure 212 of the stacked drying chamber mechanism 200, and the outlet end 302 is connected to the vibration mechanism 400. After the target product tray in the stacked drying chamber mechanism 200 is dried, it is conveyed to the vibration mechanism 400 through the limiting output mechanism 300. The limiting output mechanism 300 includes a second conveyor network and a second limiting plate set at a preset distance on the second conveyor network. The dried target product tray is connected to the inlet end 301 of the second conveyor network through the outlet connection structure 212. The second baffle on the second conveyor network is used to control the spacing of the target product tray during conveying and to prevent the target product tray from moving when it is conveyed upward. It is then conveyed to the vibration mechanism 400 through the outlet end 302 at a set distance.

[0028] The vibration mechanism 400 includes a vibratory plate 401, a conveyor network 402, and a receiving plate 403. The conveyor network 402 is disposed on the vibratory plate 401 and is connected to the discharge end 302 of the limit output mechanism 300. The receiving plate 403 is disposed below the vibratory plate 401. When the target product plate reaches the conveyor network 402 of the vibration mechanism 400 through the discharge end 302 of the second conveyor network, the positioning sensor and tensioning component on the vibratory plate 401 work. The positioning sensor transmits the data information of the target product plate receiving the conveyor network 402 to the control terminal according to the set target position. The control terminal controls the rotation to stop and then controls the tensioning component to clamp the target product plate. Then the vibratory plate 401 starts to work, shaking off the insect excrement and debris in the target product plate through the fine mesh of the target product plate during vibration. The shaken insect excrement and debris fall into the receiving plate 403 through the conveyor network 402.

[0029] Working principle: The leveling and limiting input mechanism 100 conveys the target product tray through the first conveyor network and the first limiting plate. After the scraper levels the black soldier fly larvae in the tray, it is sent into the stacked drying chamber mechanism 200 through the feeding connection structure 211. Inside the stacked drying chamber, the left and right conveyor networks 202, which are arranged in multiple layers and vertically alternately, form a "Z" shape under the control of independent rotating shafts and through the material conversion interface 203. The T-shaped conveying path, the hot air distribution port of the dual-air-mouth circulating heat exchange mechanism 500 is adapted to the gap between the conveyor mesh layers. The high-temperature hot air generated by the heat exchanger 501 enters the blower duct 502 through the first air inlet, and then penetrates the material layer laterally through the hot air distribution port to achieve uniform drying. At the same time, the waste heat recovery unit 503 recovers the heat of the humid air, and mixes it with the fresh hot air through the second air inlet for recycling. The dried target product tray is transferred to the limiting output mechanism 300 through the discharge connection structure 212. The spacing is controlled by the second conveyor mesh and the second limiting plate and conveyed to the vibration mechanism 400. The vibration plate 401 of the vibration mechanism 400 starts working after the positioning sensor positions it and the tensioning component clamps the target product tray, shaking the insect excrement and debris through the mesh to the receiving plate 403, completing the efficient drying and impurity separation of the black soldier fly.
