Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a food waste treatment bin. Background Technology

[0002] Black soldier flies, also known as black water fly larvae, are saprophytic insects belonging to the family Banditidae. They primarily feed on animal feces and decaying organic matter. Life cycle: Approximately 30 days, including four stages: egg, larva, pupa, and adult. Reproductive capacity: They can lay about 500 eggs at a time, which hatch into larvae within 24 hours. Diet: The larvae are saprophytic, mainly feeding on animal feces and decaying organic matter.

[0003] Black soldier flies are highly effective at killing germs in garbage, quickly digesting and processing food waste, and converting it into their own nutrients. Furthermore, black soldier fly larvae can be collected, crushed, and dried to replace soybean meal, fishmeal, etc., as a source of feed protein. They can also be used directly to feed frogs, turtles, chickens, ducks, etc.

[0004] However, there is currently no technology that utilizes the growth characteristics of black soldier flies to process food waste. Utility Model Content

[0005] In view of this, the present invention provides a food waste treatment bin, the main purpose of which is to treat food waste by cultivating black soldier flies.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] This utility model provides a food waste treatment bin, which includes: a bin body, a breeding area and an adult insect area;

[0008] The box is equipped with a partition to divide the box into an upper space and a lower space, and there is a gap between one side of the partition and the inner wall of the box.

[0009] The breeding area includes a larval area and a pre-pupae platform, which are arranged sequentially at the bottom of the lower space, with the pre-pupae platform located directly below the interval.

[0010] The adult insect area includes multiple oviposition plates and multiple induction lamps. The multiple oviposition plates are arranged vertically in sequence in the upper space, and each oviposition plate corresponds to one of the induction lamps.

[0011] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0012] Optionally, it also includes a pull-out box, each of the oviposition plates including multiple flaps arranged in sequence, the central axis of each flap being rotatably connected to the opposite side wall of the box, the central axes of the multiple flaps being connected in sequence through a linkage mechanism, and the pull-out box being slidably disposed below the oviposition plate.

[0013] Optionally, a crank is also included, which is fixedly connected to the central axis of one of the flaps.

[0014] Optionally, it also includes a ramp, the lower end of which is connected to the larval area and the upper end of which is connected to the prepupae platform.

[0015] Optionally, it may also include multiple drawers, each of which is slidably disposed in the larval area.

[0016] Optionally, the larval area is provided with multiple slide rails, and each drawer is slidably connected to one of the slide rails.

[0017] Optionally, it also includes multiple gravity sensors and multiple electromagnetic ejection mechanisms. Each gravity sensor is disposed inside one of the slide rails, and each electromagnetic ejection mechanism is fixedly installed at the end of one of the slide rails. The gravity sensor is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the electromagnetic ejection mechanism.

[0018] Optionally, a collection box is also included, which is disposed below the pre-pupa platform, and the collection hole of the pre-pupa platform is connected to the collection box.

[0021] By employing the above technical solution, this utility model has at least the following advantages:

[0022] Fermented kitchen waste is laid in the larval area, and black soldier fly larvae feed is sprinkled on the kitchen waste. As the black soldier flies convert the kitchen waste into their own nutrients, the larvae gradually go through the first, second, and third instar stages and become pupae. The number of pupae gradually increases, and the pupae crawl to the prepupal platform. The prepupae emerge as adults, and under the influence of the induction light, the adults fly upward to each oviposition plate to lay their eggs. People can collect the larvae that hatch from the eggs. Some of the larvae are further processed to increase their added value, while the other part of the larvae are sprinkled back onto the kitchen waste in the larval area.

[0023] Through this cycle, kitchen waste is gradually consumed, thus preventing environmental pollution. Attached Figure Description

Detailed Implementation

[0034] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1 to 4 As shown, an embodiment of this utility model provides a kitchen waste treatment bin, which includes: a bin body 1, a breeding area and an adult insect area;

[0037] The box 1 is equipped with a partition 2 to divide the box 1 into an upper space and a lower space. There is a gap 3 between one side of the partition 2 and the inner wall of the box 1.

[0038] The breeding area includes a larval area and a pre-pupae platform 4, which are arranged sequentially at the bottom of the lower space. The pre-pupae platform 4 is located directly below the interval 3.

[0039] The adult area includes multiple oviposition plates 5 and multiple induction lamps 6. The multiple oviposition plates 5 are arranged vertically in the upper space, and each oviposition plate 5 corresponds to one of the induction lamps 6.

[0040] The working process of a food waste disposal bin is as follows:

[0041] Fermented kitchen waste is laid in the larval area, and black soldier fly larvae feed is sprinkled on the kitchen waste. As the black soldier flies convert the kitchen waste into their own nutrients, the larvae gradually go through the first, second, and third instar stages and become pupae. The number of pupae gradually increases, and the pupae crawl to the prepupal platform 4. The prepupae emerge as adults and fly upwards to each oviposition plate 5 under the light of the induction lamp 6. They lay their eggs on the oviposition plate 5. People can collect the larvae that hatch from the eggs. Some of the larvae are processed to increase their added value, while the other part of the larvae are sprinkled on the kitchen waste in the larval area again.

[0042] Through this cycle, kitchen waste is gradually consumed, thus preventing environmental pollution.

[0043] Specifically, both solid meat and solid vegetable waste undergo pre-fermentation before being introduced into the larval area. The fermentation process involves high-temperature sterilization followed by fermentation in a fermentation chamber for 8-10 days under the action of aerobic microorganisms. During this period, continuous ventilation is required at both the top and bottom of the fermentation chamber. This design utilizes the principle of high-temperature drying and sterilization. However, due to the high composition of kitchen waste, some toxic microorganisms can adversely affect the growth of black soldier flies, posing a significant safety hazard. After high-temperature treatment, the kitchen waste is placed in a constant-temperature fermentation chamber where the crushed waste undergoes microbial fermentation. This fermentation process creates a more favorable environment for black soldier fly growth, providing a suitable breeding environment for aerobic microorganisms.

[0044] like Figure 3 and Figure 4As shown, in a specific embodiment, it also includes a pull-out box 7. Each oviposition plate 5 includes multiple flaps 501 arranged in sequence. The central axis of each flap 501 is rotatably connected to the opposite side wall of the box body 1. The central axes of the multiple flaps 501 are connected in sequence through a linkage mechanism 8. The pull-out box 7 is slidably disposed below the oviposition plate 5.

[0045] In this embodiment, specifically, there is a limiting rod 502 between adjacent flaps 501. The two ends of the limiting rod 502 are respectively fixedly connected to the side wall of the box 1. The opposite axial sides of the limiting rod 502 are respectively designed with bevels, and the opposite sides of the flaps 501 match the bevel design of the limiting rod 502.

[0046] During normal egg-laying by adult insects, multiple flaps 501 and multiple limiting rods 502 alternately and sequentially fit together to form a plane. Under the influence of the induction lamp 6, the eggs laid by the adult insects are received on multiple flaps 501. As the number of eggs and larvae accumulated on the flaps 501 gradually increases, people can use the linkage mechanism 8 to make multiple flaps 501 rotate synchronously, so that the eggs and larvae fall downwards into the pull-out box 7. Pulling out the pull-out box 7 makes it easy to take out the eggs and larvae of black soldier flies, which facilitates the subsequent processing of larvae or the cyclical cultivation of black soldier flies.

[0047] After the larvae fall downwards, multiple flaps 501 rotate in the opposite direction, and the multiple flaps 501 form a plane again, which makes it easier to continue to receive black soldier fly eggs.

[0048] like Figure 3 and Figure 6 As shown, in a specific embodiment, a crank 9 is also included, which is fixedly connected to the central axis of one of the flaps 501.

[0049] In this embodiment, specifically, when people need to rotate multiple flaps 501, they can hold the crank handle 9 to rotate the multiple flaps 501.

[0050] The handle 9 is fixedly connected to the central axis of the flap 501 at the end of the oviposition plate 5. When multiple flaps 501 and multiple limiting rods 502 alternately fit together to form a plane, the handle 9 is located on the far side of the oviposition plate 5. Due to the weight of the handle 9, the multiple flaps 501 will not automatically flip to the vertical position. Only by manually turning the handle 9 can the multiple flaps 501 be rotated to the vertical position so that the eggs and larvae can fall downwards.

[0051] like Figure 4 As shown, in a specific embodiment, it also includes a ramp 10, the lower end of which is connected to the larval area and the upper end of which is connected to the prepupa platform 4.

[0052] In this embodiment, specifically, when the inclination angle of the ramp plate 10 is 30° to 60°, because the black soldier fly pupa has the habit of climbing slopes when it grows to the sixth instar, the ramp plate 10 is set up to facilitate the movement of the black soldier fly pupa towards the pre-pupa platform 4.

[0053] like Figure 4 and Figure 5 As shown, in a specific embodiment, it also includes multiple drawers 11, which are slidably disposed in the larval area.

[0054] In this embodiment, specifically, multiple drawers 11 are filled with a certain amount of kitchen waste. When the kitchen waste in a certain drawer 11 is completely consumed by the black soldier fly, the drawer 11 is pulled out and kitchen waste is added.

[0055] like Figure 7 and Figure 8 As shown, in a specific embodiment, the larval area is provided with multiple slide rails 12, and each drawer 11 is slidably connected to one of the slide rails 12.

[0056] In this embodiment, specifically, the bottom surfaces of drawer 11 are slidably connected to slide rails 12 on opposite sides, making it easier to pull out or push drawer 11 into the larval area.

[0057] like Figure 7 and Figure 8 As shown, in a specific embodiment, it also includes multiple gravity sensors 13 and multiple electromagnetic push-out mechanisms 14. Each gravity sensor 13 is correspondingly disposed inside one of the slide rails 12, and each electromagnetic push-out mechanism 14 is fixedly installed at the end of one of the slide rails 12. The gravity sensor 13 is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the electromagnetic push-out mechanism 14.

[0058] In this embodiment, specifically, the controller has a level value representing the lower limit of the weight of drawer 11. When drawer 11, which is filled with kitchen waste, is pushed into the larval area, the black soldier fly gradually consumes the kitchen waste. Gravity sensor 13 detects that the weight of drawer 11 gradually decreases. When the weight of drawer 11 drops to the lower limit, gravity sensor 13 sends an electrical signal to the controller. The controller controls the electromagnetic coil of electromagnetic push mechanism 14 to be energized, driving the push rod to push drawer 11 along slide rail 12 out of the larval area, so that people can add kitchen waste to drawer 11 in time.

[0059] Specifically, the height of the gravity sensor 13 is higher than the height of the slide rail 12, and the lower side of the end of the drawer 11 adopts an arc design. When the drawer 11 is just pushed into the larval area, the drawer 11 moves inward along the slide rail 12. When the arc surface of the drawer 11 contacts the gravity sensor 13, the drawer 11 is slightly lifted and moved inward. In this way, the weight of the drawer 11 is applied to the gravity sensor 13, which facilitates the monitoring of the weight of the drawer 11.

[0060] like Figure 9 As shown, specifically, the electromagnetic ejection mechanism 14 includes an electromagnetic valve body, an electromagnetic coil 1401 disposed within the electromagnetic valve body, a piston rod 1402, and a spring 1403. The piston rod 1402 is axially fixedly connected to a retaining ring 1404. When the electromagnetic coil is energized, the piston rod 1402 overcomes the elastic force of the spring 1403, extends out of the electromagnetic valve body, and pushes the drawer 11. When the electromagnetic coil 1401 is de-energized, the spring 1403 pushes the retaining ring 1404, and the piston rod 1402 retracts into the electromagnetic valve body.

[0061] like Figures 1 to 4 As shown, in a specific embodiment, a collection box 15 is also included. The collection box 15 is disposed below the pre-pupa platform 4, and the collection hole 16 of the pre-pupa platform 4 is connected to the collection box 15.

[0062] In this embodiment, specifically, after the black soldier fly pupae move to the pre-pupa platform 4, some pupae fall into the collection box 15 through the collection hole 16, which facilitates the subsequent processing to obtain high-quality insect protein and insect sand. The insect protein can be processed into animal protein feed or converted into biodiesel, and the insect sand can be processed into organic fertilizer. The other part emerges into adult insects and flies upward to lay eggs.

[0063] like Figure 2 and Figure 5 As shown, in a specific embodiment, it also includes two guide plates 17, each guide plate 17 being fixedly connected to the ramp plate 10 and the pre-pupa platform 4 respectively, and the collection hole 16 is located between the two guide plates 17.

[0064] In this embodiment, specifically, two guide plates 17 are arranged side by side. The pupa between the two guide plates 17 crawls upward and eventually falls into the collection box 15 through the collection hole 16. The pupa outside the two guide plates 17 crawls upward and emerges as an adult on the prepupa platform 4. The slope area is divided by the two guide plates 17, thereby controlling the proportion of prepupa being diverted, and thus controlling the proportion of prepupa emergence and collection.

[0065] like Figure 1 As shown, in a specific embodiment, an inspection port is provided on the side wall of the box 1 away from the partition 2, and a sealing door panel 18 is installed on the inspection port.

[0066] In this embodiment, specifically, after the device has been used for a long time, people can open the sealed door 18 to facilitate cleaning and maintenance of the internal environment of the box 1 through the inspection port.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
