Description

Technical Field

[0001] This invention relates to a manure treatment device, and more particularly to a multipurpose organic waste insect treatment device, system, and method. Background Technology

[0002] In people's production and daily life, organic waste such as feces and kitchen waste is constantly generated, including human excrement, animal feces, and food scraps. Improper treatment of this organic waste will cause serious environmental and odor pollution, and is also a waste of resources. Using saprophytic insects for treatment is a good option, solving environmental problems and turning waste into treasure. However, most existing processes are centralized, involving multiple steps and high costs. If there were a small-scale, intelligent insect-based treatment device for organic waste that could be used locally, it would significantly reduce collection and transportation costs, while also reducing pollution during transportation. Therefore, researching and developing a small-scale, intelligent insect-based organic waste treatment device and technology is of great significance for the treatment of feces and food scraps in urban areas and for the treatment of small-scale livestock manure in rural areas.

[0003] The treatment of fecal waste has certain unique characteristics. Fecal waste is primarily discharged into septic tanks. Septic tanks, as intercepting facilities designed to prevent blockages in drainage pipes, play a positive role in intercepting and settling large particles of impurities in sewage, preventing sewage pipe blockages, and protecting the environment. Although septic tanks are widely used in urban residential areas, their treatment process is simple and cannot completely remove various bacteria and foul odors from the fecal residue, and the remaining residue is difficult to recycle. The fecal residue trapped in the septic tank is generally transported to a wastewater treatment plant for centralized processing using vacuum trucks. The above methods are complex and costly. Data shows that fecal waste, when processed into agricultural fertilizer, contains not only the nutrients needed by crops but also nitrogen-fixing, phosphorus-solubilizing, and potassium-solubilizing bacteria. It can prevent soil compaction, improve soil fertility, enhance grain quality, and increase crop yield, possessing advantages unmatched by chemical fertilizers. If urban fecal waste can be rationally treated and utilized, its resource benefits are significant. Therefore, research on urban fecal waste treatment is of great importance. Summary of the Invention

[0004] This invention provides a multi-purpose organic waste insect treatment device, system and method, which can solve the existing urban manure and food waste treatment problems in a localized, miniaturized and automated manner, and can also solve the problem of manure treatment for small-scale livestock farming in rural areas.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A multi-purpose organic waste insect treatment device includes a box body with several discharge mechanisms at the bottom and an insect discharge mechanism at the top. The box body also has a material layer.

[0007] The discharge mechanism includes several rotating shafts and a stirring mechanism connected together. The rotating shafts are installed together with the stirring mechanism. The stirring mechanism includes stirring teeth. The stirring teeth on adjacent rotating shafts are staggered. When the staggered stirring teeth are at rest, they form a support mechanism to prevent material leakage. The rotating shafts are connected to a power mechanism.

[0008] Furthermore, preferably: the stirring mechanism includes a main shaft, which is mounted together with the rotating shaft, and a plurality of stirring teeth are alternately arranged on the main shaft;

[0009] Alternatively, the stirring mechanism may include several spiked plates with stirring teeth, the two ends of which are fixed to the rotating shaft via connecting parts. Further, preferably, the material layers from top to bottom are a rearing layer, a buffer layer, and a dry material layer, the heights of which ensure that the temperature of the rearing layer during air drying does not affect the normal growth or survival of the insects.

[0010] Furthermore, preferably: the insect discharge mechanism includes an insect collection trough located on the top of the box, and an insect collection tube is provided on the insect collection trough.

[0011] Furthermore, preferably, the insect discharge mechanism also includes an inclined insect-guiding corrugated plate disposed inside the box, the insect-guiding corrugated plate being connected to the insect-collecting trough.

[0012] Furthermore, preferably, the box body is provided with a sealing cover, and the sealing cover is provided with an insect inlet, a feed inlet, an exhaust outlet and / or a lighting mechanism.

[0013] Furthermore, preferably: a heating mechanism is provided inside the box;

[0014] And / or the bottom of the enclosure is provided with a bracket or feet;

[0015] And / or the enclosure is provided with a first air inlet and / or a second air inlet;

[0016] And / or the lower part of the discharge mechanism is provided with a discharge hopper, and the discharge hopper is provided with a discharge valve;

[0017] And / or the aforementioned box body, discharge hopper and sealing cover are provided with a heat insulation layer;

[0018] And / or the rotating shafts are interconnected via sprockets or gears. This invention also provides a multi-purpose organic waste insect treatment system, including the insect treatment device, deodorization mechanism, automatic insect feeding mechanism, feeding mechanism, air supply mechanism, temperature control mechanism, weighing and collecting mechanism, and control system. The deodorization mechanism is connected to the exhaust port, the automatic insect feeding mechanism is connected to the insect feeding port, the feeding mechanism is connected to the feeding port, the air supply mechanism is connected to the first air inlet and the second air inlet respectively, the temperature control system includes a temperature and humidity sensor, which is installed on the breeding layer, buffer layer, and / or manure discharge layer of the box, the weighing and collecting mechanism is located at the lower part of the collecting pipe, and the discharging mechanism, deodorization mechanism, automatic insect feeding mechanism, feeding mechanism, air supply mechanism, temperature control mechanism, and weighing and collecting mechanism are respectively connected to the control system.

[0019] Furthermore, preferably, the feeding mechanism includes a screening mechanism and / or a crushing mechanism.

[0020] This invention also provides an integrated continuous insect breeding, drying, and manure removal method, employing the insect treatment system of this invention, including the following steps:

[0021] (1) Place dry insect excrement or other dry substrate into the box to form a buffer layer and a dry material layer. The height of the buffer layer and the dry material layer is adjusted according to the overall height of the box and the weight of the feed so that the height of the buffer layer and the dry material layer can ensure that the temperature of the breeding layer during air drying does not affect the normal growth or survival of the insects.

[0022] (2) Connect the material supply pipe to the feeding mechanism, and use the screening mechanism to feed the solid part as feed for raising insects, which enters the box to form a feeding layer. The liquid part returns to the material supply pipe through the pipe.

[0023] (3) Introduce saprophytic insects of different ages into the box. The proportion of insects introduced is determined based on the weight of the solid portion filtered by the material supply pipe each day, ensuring that the introduced saprophytic insects will completely convert the feces and waste entering the box within one day.

[0024] (4) During the feeding process, the temperature and humidity sensor detects the temperature of the breeding environment and controls the temperature and humidity of the breeding environment. The feeding mechanism sends the sieved solid part into the box from time to time, and the breeding exhaust enters the deodorization mechanism for treatment before being discharged.

[0025] (5) Mature insects enter the weighing and collecting mechanism through the insect collection trough and insect exit hole for weighing and collection.

[0026] (6) The control system controls the automatic insect feeding mechanism to put in new larvae according to the weight of the collected insects, and controls the discharge mechanism to start discharging. When discharging, the control system starts the air supply mechanism according to the data of the temperature and humidity sensor. When the humidity does not meet the discharge requirements, the control system starts the air supply mechanism to send in dry hot air to dry it so that it meets the discharge standard.

[0027] (7) Repeat steps (5) and (6) to achieve continuous treatment of fecal waste.

[0028] The beneficial effects of this invention are:

[0029] The present invention discloses a multi-purpose organic waste insect treatment device, the discharge mechanism of which includes several rotating shafts interconnected together. Each rotating shaft is equipped with stirring teeth, with the stirring teeth on adjacent rotating shafts arranged alternately. The rotating shafts are connected to a power mechanism. The alternating arrangement of the stirring teeth has the following advantages:

[0030] (1) The combination of the rotating shaft and the staggered stirring teeth, when stationary, the staggered stirring teeth are on the same horizontal plane, so that the insect excrement will not fall off during the breeding process, and plays a supporting and sealing role.

[0031] (2) The staggered mixing teeth have a turning effect on the squeezed insect excrement, which can be discharged smoothly;

[0032] (3) Small gaps will be left between the stirring teeth, which is conducive to ventilation and drying.

[0033] It can be seen that the discharge mechanism of the present invention has four functions: sealing, support, discharge and ventilation.

[0034] The present invention divides the box into a breeding layer, a buffer layer and a dry feed layer from top to bottom. The height of the buffer layer and the dry feed layer can ensure that the temperature of the breeding layer during air drying does not affect the normal growth or survival of the insects. It can realize the continuous and simultaneous operation of breeding, air drying, manure removal and insect removal, which can effectively reduce equipment investment and make it more widely used.

[0035] The device of the present invention has a simple structure and is easy to operate. The insects produced can be used as protein feed, and the insect excrement can be used as organic fertilizer. It can realize the automated treatment of manure and waste, and realize the resource treatment and utilization of manure. Attached Figure Description

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figure 1 and 2 As shown, a multi-purpose organic waste insect treatment device includes a support frame 9 and a housing 14, with the housing 14 mounted on the support frame 9. The support frame 9 serves to fix and install the housing 14. It can be made of different materials depending on the actual situation, but is generally made of I-beams. It can be configured as legs, such as casters, as needed. In this embodiment, no moving mechanism is provided.

[0051] The box 14 is the main component for insect breeding. It is generally a square box or a round box. In this embodiment, a square box is used. The box 14 is generally made of corrosion-resistant materials, such as stainless steel or tempered plastic. In this embodiment, stainless steel is used.

[0052] The bottom of the box 14 is equipped with several discharge mechanisms, and the lower part of the discharge mechanism is equipped with a first air inlet 10. The top of the box 14 is equipped with an insect discharge mechanism. The box 14 consists of a breeding layer 2, a buffer layer 3, and a dry feed layer 4 from top to bottom. The height of the buffer layer 3 and the dry feed layer 4 can ensure that the temperature of the breeding layer 2 during air drying does not affect the normal growth or survival of the insects. There is no clear dividing line between the breeding layer 2, the buffer layer 3, and the dry feed layer 4 inside the box 14. It can be seen that the amount of material to be processed and the size of the equipment are determined. The main purpose is to ensure that the hot air introduced from the dry feed layer 4 will not have a significant impact on the life or survival of the insects in the breeding layer 2 while drying, and will not cause the insects to die.

[0053] The discharge mechanism includes several interconnected rotating shafts 6 and a stirring mechanism. The rotating shafts 6 are mounted together with the stirring mechanism, which includes stirring teeth. The stirring teeth on adjacent rotating shafts are staggered, and when stationary, the staggered stirring teeth form a support mechanism to prevent material leakage. The rotating shafts are connected to a power mechanism. The rotating shafts 6 are interconnected via sprockets 30 or gears 5.

[0054] like Figure 5 As shown, the stirring mechanism includes a main shaft 29, which is mounted together with the rotating shaft, and a plurality of stirring teeth are staggered on the main shaft 29.

[0055] In this embodiment, each rotating shaft 6 is equipped with a gear 5, which meshes with each other to connect the rotating shafts 6 together. There are at least two rotating shafts 6; the specific number depends on the size of the housing 14. In this embodiment, 12 rotating shafts 6 are used. The stirring teeth are generally circular stirring teeth 15 or square stirring teeth 36. This embodiment uses circular stirring teeth, as this shape provides better sealing and support, preventing feces from falling out. Of course, they can be set as needle-shaped or square stirring teeth, but the needle tip of the needle-shaped stirring teeth should be as short as possible to prevent leakage when the rotating shaft 6 is stationary.

[0056] The discharge mechanism can be set according to the actual situation; generally, one discharge mechanism is sufficient. For example... Figure 6 As shown, if the material has high moisture content and a large quantity, causing severe compression and affecting air permeability, multiple discharge mechanisms can be installed, with a branch outlet between two discharge mechanisms to quickly dry the material between them. Figure 6 Two discharge mechanisms are set up in the middle.

[0057] When configured with two discharge mechanisms, a third air inlet can be installed between the two discharge mechanisms to deliver dry hot air for drying the material between the two discharge mechanisms.

[0058] The function of the power mechanism is to drive the gears on the rotating shaft to rotate. Any power mechanism that can perform the above function is acceptable. In this embodiment, the power mechanism uses a motor 8 and a pulley. The pulley 7 is mounted on a rotating shaft 6 and is connected to the motor via a belt. The gears 5 on the rotating shaft mesh with each other.

[0059] The main function of the insect-collecting mechanism is to collect mature insects according to their living habits. Different structures can be designed based on the different habits of various insects. The saprophytic insects (such as black soldier fly larvae) raised in this invention generally crawl out of their feed in the later stages of maturation to seek a dry, quiet environment for pupation. Therefore, the insect-collecting mechanism of this invention includes an insect-collecting trough 1 located at the top of the box 14, with an insect-collecting hole on it. The insect-collecting trough 1 can be located around the box 14, or in one or more locations, as long as insects can crawl in for collection. An insect-collecting tube 13 can be installed below the insect-collecting hole for convenient insect collection.

[0060] The bottom of the box 14 is well sealed due to the interaction between the discharge mechanism, the dry material layer 4, and the buffer layer 3. However, in order to make better use of the drying hot air, a discharge hopper 11 can be set at the bottom of the discharge mechanism. A discharge valve 12 is set on the discharge hopper 11, and the first air inlet 10 is set on the discharge hopper 11.

[0061] The device in this embodiment can be used for insect rearing. After processing and crushing organic waste suitable for insects, materials of different heights are filled according to the height of the buffer layer 3 and the dry material layer 4 to ensure that the temperature of the rearing layer 2 during air drying does not affect the normal growth or survival of the insects, and then the insects are reared.

[0062] During the rearing process, new raw materials are continuously added. Mature insects crawl out of the box 14 and enter the insect collection trough 1 for collection. When the insect excrement in the box 14 reaches a certain thickness, hot dry air is introduced through the first air inlet 10. The hot dry air passes through the dry material layer 4, the buffer layer 3, and the rearing layer 2 in sequence, drying the insect excrement in the dry material layer 4 to meet the discharge standard. During the drying process, the hot dry air moves from bottom to top, with the temperature continuously decreasing and the humidity continuously increasing. This ensures that when it reaches the rearing layer 2, it does not cause large fluctuations in the temperature of the raw materials in the rearing layer 2, thus maintaining the requirements for insect growth or survival. Then, the discharge mechanism is activated to discharge the insect excrement from the dry material layer 4 as raw material for organic fertilizer. The insect excrement in the buffer layer 3 falls to the dry material layer 4 under the action of gravity, filling the dry material layer 4. The insect excrement at the bottom of the rearing layer 2 falls to become the buffer layer 3, thus providing space in the rearing layer 2 for the addition of new raw materials. This achieves continuous feeding, rearing, insect discharge, and excrement discharge in a cyclical operation, and can also realize automated production.

[0063] The device in this embodiment can be used not only for insect rearing, but also for separating insect excrement after other insect rearing. The method of use is as follows:

[0064] 1. The material from insect rearing is introduced into the box 14 of this invention;

[0065] 2. Introduce hot dry air (or allow the material to ferment and generate heat on its own or use other heating methods);

[0066] 3. The material heats up from bottom to top;

[0067] 4. The insect moves upwards;

[0068] 5. Once the insects enter the insect collection trough, the discharge mechanism is activated to discharge the insect excrement from the dry material layer 4.

[0069] 6. Continue to feed in the insects and insect excrement to be separated, and continuously carry out operations such as separating insect excrement and insects, drying insect excrement, and discharging.

[0070] Example 2

[0071] like Figure 3As shown, a multi-purpose organic waste insect treatment device has a structure basically similar to the embodiment, except that the upper part of the box 14 is equipped with a sealing cover 17, which can be set according to different breeding environments or insects, to seal the box 14 and reduce the pollution of the environment by the exhaust gas generated during the breeding process. The sealing cover 17 is provided with an insect inlet 18, a feeding inlet 28 (located opposite the insect inlet 18, not shown in the figure), and an exhaust outlet 16. Heating mechanisms, supplemental lighting mechanisms, and trace element supplementation mechanisms can be set according to the different living habits of insects.

[0072] A second air inlet 19 or an exhaust vent can be installed on the housing 14 according to actual needs. The exhaust vent on the housing can effectively remove excessively humid air in a timely manner, preventing it from affecting the materials on the upper layer.

[0073] Setting up two air inlets makes it easier to precisely control the breeding environment. The second air inlet 19 is used for ventilation, oxygenation and heat exchange control during the breeding process; the first air inlet 10 is used for drying and manure removal by passing hot dry air. Of course, the first air inlet 10 can also be used for ventilation, oxygenation and heat exchange operations during the breeding process.

[0074] Temperature control is generally required during insect rearing. Therefore, insulation layers are provided on the box 14, the discharge hopper 11, and the sealing cover 17 to effectively improve the utilization rate of heat sources and reduce operating costs.

[0075] Example 3

[0076] like Figure 4 As shown, a multi-purpose organic waste insect treatment system includes a multi-purpose organic waste insect treatment device, a deodorization mechanism 21, an automatic insect feeding mechanism 20, a feeding mechanism 24, an air supply mechanism 27, a temperature control mechanism, a weighing and collecting mechanism 22, and a control system.

[0077] The structure of the multipurpose organic waste insect treatment device is the same as that in Example 2, and will not be described again.

[0078] The deodorization mechanism 21 is connected to the exhaust port 16, the automatic insect feeding mechanism 20 is connected to the insect feeding port 18, the feeding mechanism 24 is connected to the feeding port 28, the air supply mechanism 27 is connected to the first air inlet 10 and the second air inlet 19 respectively, the temperature control system includes a temperature and humidity sensor 23, the temperature and humidity sensor 23 is installed on the breeding layer 2, the buffer layer 3 and / or the manure discharge layer of the box 14, the weighing and collecting insect mechanism 22 is installed at the lower part of the collecting pipe 13, and the discharging mechanism, deodorization mechanism 21, automatic insect feeding mechanism 20, feeding mechanism 24, air supply mechanism 27, temperature control mechanism and weighing and collecting insect mechanism 22 are respectively connected to the control system.

[0079] The deodorization mechanism 21 is mainly used for the purification of waste gas during the breeding process. The appropriate deodorization mechanism 21 can be selected according to different raw materials and insects. The deodorization mechanism 21 is a conventional equipment and will not be described in detail.

[0080] The automatic insect feeding mechanism 20 is mainly used for feeding insect larvae. Appropriate equipment can be selected based on the habits of different insects. If breeding black soldier fly larvae or similar insects, an insect feeding system based on CN110150235A, which enables automated feeding of small black soldier fly larvae over multiple days / times, can be selected. The specific structure is described in detail in this patent.

[0081] The feeding mechanism 24 is mainly used for the preliminary processing of raw materials. Depending on the actual situation, it can be configured with different functions. In this embodiment, the feeding mechanism 24 includes a hopper 25 and a crushing feeding mechanism 26. This embodiment uses a screw feeder for the feeding mechanism, and a solid-liquid separation mechanism can also be provided as needed. The separated solids are used as raw materials to feed insects.

[0082] The air supply mechanism 27 primarily provides the system with hot, dry air for drying and controls the temperature, humidity, and dissolved oxygen in the rearing environment. It can use a fan with a heating function, or two fans: one for providing hot, dry air and one for controlling the rearing environment. The fan providing hot, dry air is connected to the first air inlet 10, and the fan for controlling the rearing environment is connected to the second air inlet 19. Of course, when the ambient air temperature and humidity are suitable, only one fan for controlling the rearing environment is needed to achieve both rearing and drying; a separate hot, dry air fan is not required.

[0083] The temperature control mechanism is used to detect the temperature and humidity of the aquaculture drying environment. It generally uses temperature and humidity sensors, and usually two temperature and humidity sensors are set. One is set in the dry feed layer 4 to detect the temperature and humidity of the manure discharge, and the other is set in the breeding layer 2 to detect the temperature and humidity of the breeding environment.

[0084] The weighing and insect collection mechanism 22 is mainly used to detect the weight of the insects and to control the discharge and feeding of insects.

[0085] The system of the present invention can also be equipped with a solar power supply system to provide power for system operation.

[0086] Control systems typically use programmable microcontrollers for overall system monitoring and control; this is common knowledge and will not be explained in detail.

[0087] Example 4

[0088] An integrated continuous insect breeding, drying, and manure removal method, using the processing system of Example 3, includes the following steps:

[0089] (1) Place dry insect excrement or other dry substrate into the box 14 to form a buffer layer 3 and a dry material layer 4. The height of the buffer layer 3 and the dry material layer 4 is adjusted according to the overall height of the box 14 and the weight of the feed so that the height of the buffer layer 3 and the dry material layer 4 can ensure that the temperature of the breeding layer 2 during air drying does not affect the normal growth or survival of the insects.

[0090] (2) Connect the material supply pipe to the feeding mechanism, and use the screening mechanism to feed the solid part as feed for raising insects, which enters the box 14 to form a feeding layer. The liquid part returns to the material supply pipe through the pipe.

[0091] (3) In the box 14, put saprophytic insects of different ages into the box. The proportion of the insects put into the box is determined according to the weight of the solid part filtered by the material supply pipe every day, so as to ensure that the saprophytic insects put into the box 14 will completely convert the feces and sewage that enter the box 14 within one day.

[0092] (4) During the feeding process, the temperature and humidity sensor 23 detects the temperature of the breeding environment and controls the temperature and humidity of the breeding environment. The feeding mechanism sends the sieved solid part into the box 14 from time to time. The breeding exhaust gas enters the deodorization mechanism 21 for treatment and then is discharged.

[0093] (5) Mature insects enter the weighing and collecting mechanism 22 through the insect collecting trough 1 and the insect exit hole for weighing and collection.

[0094] (6) The control system controls the automatic insect feeding mechanism 20 to feed new larvae according to the weight of the collected insects, and controls the discharge mechanism to discharge the material. When discharging the material, the control system starts the air supply mechanism 27 according to the data of the temperature and humidity sensor 23. When the humidity does not meet the discharge requirements, the control system starts the air supply mechanism 27 to enter the dry hot air for drying so that it meets the discharge standard.

[0095] (7) Repeat steps (5) and (6) to achieve continuous treatment of fecal waste.

[0096] Example 5

[0097] The multi-purpose organic waste insect treatment system of the present invention can be used as a mechanism integrating breeding, drying and discharging, or as a separate insect discharging and drying mechanism. The specific structure is as follows:

[0098] like Figure 7-10 As shown, an insect-discharging mechanism for organic waste includes a support 9 and a box 14, with the box 14 mounted on the support 9. The bottom of the box 14 has several discharge mechanisms, each with a discharge hopper below it. The top of the box 14 has a sealing cover 17 and an insect-discharging mechanism, with a feeding port 28 on the sealing cover 17.

[0099] The discharge mechanism includes several interconnected rotating shafts 6 and a stirring mechanism. The rotating shafts 6 are mounted together with the stirring mechanism, which includes stirring teeth. The stirring teeth on adjacent rotating shafts are staggered, and when stationary, the staggered stirring teeth form a support mechanism to prevent material leakage. The rotating shafts are connected to a power mechanism. The rotating shafts 6 are interconnected via sprockets 30 or driven gears 5.

[0100] The power mechanism in this embodiment includes a motor and a sprocket 30. The sprocket 30 is mounted on a rotating shaft, and the motor is connected to the sprocket 30 via a chain 31.

[0101] The stirring mechanism includes several spiked shaft plates 34 with stirring teeth. Both ends of each spiked shaft plate 34 are fixed to the rotating shaft 6 via connecting parts 35. In this embodiment, there are two spiked shaft plates 34, and the stirring teeth on the spiked shaft plates 34 are square stirring teeth 36. In this embodiment, the spiked shaft plates 34 are made by stamping the square stirring teeth 36 from a steel plate, which is simpler to manufacture and lower in cost compared to welding stirring teeth onto the main shaft 29.

[0102] The insect discharge mechanism includes an insect collection trough 1 located at the top of the box, and an insect collection tube 13 is provided on the insect collection trough 1.

[0103] The larvae-exiting mechanism also includes an inclined corrugated guide plate 32 disposed within the box, which is connected to the larvae-collecting trough 1. The corrugated guide plate 32 is a plate with corrugated grooves on one side. This mechanism facilitates the rapid exit of mature larvae from the box and into the collecting trough, improving collection efficiency. A heating mechanism 33 is installed within the box. The heating mechanism 33 typically employs either electric or water heating; in this embodiment, a water heating mechanism is used. Compared to ventilation heating during rearing, the heating mechanism allows for faster temperature rise, facilitating the quick separation of mature larvae.

[0104] The operation process of this embodiment:

[0105] The heating mechanism raises the temperature inside the chamber to the set temperature. Then, the feed after the insects have been fed is added through the feeding port 28. Under high temperature, the insects in the feed crawl into the insect collection trough through the insect guide corrugated plate and are finally collected and separated through the insect collection pipe. The insect sand accumulates inside the chamber. When the insect sand in the chamber accumulates to a certain height, the power mechanism is activated to drive the rotating shaft to rotate and discharge the insect sand from the chamber through the discharge hopper. At the same time, new materials are continuously added and the speed of the power mechanism is controlled to achieve continuous addition of mixture and continuous discharge of insect sand. This achieves continuous operation of insect separation and insect sand discharge in the mixture, effectively improving the separation efficiency.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.

The rotating shafts and the stirring mechanism are mounted together. The stirring mechanism includes stirring teeth, which are staggered on adjacent rotating shafts. When stationary, the staggered stirring teeth form a support mechanism to prevent material leakage. The rotating shafts are connected to a power mechanism. The material layer consists of a breeding layer, a buffer layer, and a dry feed layer from top to bottom. The height of the buffer layer and the dry feed layer ensures that the temperature of the breeding layer does not affect the normal growth or survival of the insects during air drying. A discharge hopper is located at the bottom of the discharge mechanism, and a discharge valve is installed on the discharge hopper. A first air inlet is located on the discharge hopper. During the rearing process, new feed is continuously added. Mature insects crawl out of the box and into the collection trough. When the insect excrement in the box reaches a certain thickness, hot dry air is introduced through the first air inlet. The hot dry air passes through the dry feed layer, the buffer layer, and the rearing layer in sequence, drying the insect excrement in the dry feed layer to meet the discharge standard. During the drying process, the hot dry air moves from bottom to top, with the temperature continuously decreasing and the humidity continuously increasing. When it reaches the rearing layer, it will not cause large fluctuations in the temperature of the feed material, ensuring that it still meets the requirements for insect growth or survival. Then, the discharge mechanism is activated to discharge the insect excrement from the dry feed layer as raw material for organic fertilizer. The insect excrement in the buffer layer falls to the dry feed layer under the action of gravity, filling the dry feed layer. The insect excrement at the bottom of the rearing layer falls to become the buffer layer, leaving space in the rearing layer for the addition of new feed, realizing continuous feeding, rearing, insect discharge, and excrement discharge in a cyclical operation.

9. A method of integrated continuous insect rearing, air-drying and manure removal, characterized by, The multi-purpose organic waste insect treatment system according to claim 8 includes the following steps: (1) Place dry insect excrement or other dry substrate into the box to form a buffer layer and a dry material layer. The height of the buffer layer and the dry material layer is adjusted according to the overall height of the box and the weight of the feed so that the height of the buffer layer and the dry material layer can ensure that the temperature of the breeding layer during air drying does not affect the normal growth or survival of the insects. (2) Connect the material supply pipe to the feeding mechanism, and use the screening mechanism to feed the solid part as feed for raising insects, which enters the box to form a feeding layer. The liquid part returns to the material supply pipe through the pipe. (3) Introduce saprophytic insects of different ages into the box. The proportion of insects introduced is determined based on the weight of the solid portion filtered by the material supply pipe each day, ensuring that the introduced saprophytic insects will completely convert the feces entering the box within one day. (4) During the feeding process, the temperature and humidity sensor detects the temperature of the breeding environment and controls the temperature and humidity of the breeding environment. The feeding mechanism sends the sieved solid part into the box from time to time, and the breeding exhaust enters the deodorization mechanism for treatment before being discharged. (5) Mature insects enter the weighing and collecting mechanism through the insect collecting trough and the insect exit hole, and are weighed and collected; (6) The control system controls the automatic insect feeding mechanism to feed new larvae according to the weight of the collected insects, and controls the discharge mechanism to start discharging. When discharging, the control system starts the air supply mechanism to send in hot dry air to dry the larvae according to the data of the temperature and humidity sensor. When the humidity does not meet the discharge requirements, the control system starts the air supply mechanism to dry the larvae so that they meet the discharge standards. (7) Repeat steps (5) and (6) to achieve continuous treatment of fecal waste.
