Detailed implementation manners

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The present invention provides a three-dimensional bionic conversion system for insect organic waste, including a screw conveyor, a stirring and mixing device, a multi-layer conversion rack 1, a multi-layer feeder 2, a transfer device, a turning mechanism 3, and an insect-material separation device 4.

[0025] The screw conveyor is connected to the stirring and mixing device and is used to convey materials (i.e., organic waste) into the stirring and mixing device, and the stirring and mixing device is used to perform stirring pretreatment on the materials.

[0026] As Figure 2 shown, the multi-layer conversion rack 1 includes a rack body, and a plurality of conversion boxes 11 are fixed on the rack body, and the plurality of conversion boxes 11 are arranged at intervals along the height direction of the multi-layer conversion rack 1.

[0027] In some embodiments, as Figure 5 shown, the rack body may include four columns 12, and the conversion boxes 11 may be fixed on the columns 12 by bolts. As Figure 6 shown, a support plate 15 is fixedly arranged on the rack body by bolts, support feet are arranged on the conversion boxes 11, the support feet are placed on the support plate 15, and the support feet are fixedly connected to the columns 12 by bolts.

[0028] In some embodiments, as Figure 2 shown, the multi-layer conversion rack 1 may also be modularly arranged. The multi-layer conversion rack 1 includes multiple sections of columns 12. As Figure 3As shown in the figure, a plurality of connection ports 111 are provided on both sides of the conversion box 11. A limiting plate is fixedly arranged in the middle of the connection port 111. The upper end of the column 12 can be inserted into the lower end of the connection port 111 and abutted against the limiting plate, and the lower end of the column 12 can be inserted into the upper end of the connection port 111 and abutted against the limiting plate. The column 12 and the connection port 111 are fixed by a mortise and tenon structure, thereby forming a structure of multiple conversion boxes 11. An insertion port matching the column 12 is provided on the base 14, so that the column 12 can be fixed on the base 14, and the base 14 is made of a stainless steel structure.

[0029] In addition, a threaded connection form can also be adopted. For example, Figure 4 As shown in the figure, internal thread connectors 121 and external thread connectors 122 are respectively arranged at both ends of the column 12. Internal threads are arranged on the inner wall of the internal thread connector 121, and external threads are arranged on the outer wall of the external thread connector 122. The two columns 12 can be threadedly connected through the internal thread connector 121 and the external thread connector 122, that is, the column 12 inserted from above the connection port 111 and the column 12 inserted from below the connection port 111 can be threadedly connected, and the column end faces 123 of the two columns 12 abut against both ends of the connection port 111.

[0030] For example, Figure 3 As shown in the figure, the conversion box 11 includes a bottom surface and four side surfaces. Among them, three side surfaces are perpendicular to the bottom surface, and the fourth side surface forms an obtuse angle (such as 135°) with the bottom surface, which is convenient for pouring the material out of the conversion box 11. The bottom surface of the conversion box 11 and the side surfaces perpendicular to the bottom surface are both water-permeable and air-permeable surfaces, and the side surface forming an obtuse angle with the bottom surface only includes a plastic plate, which is convenient for smooth discharging. The bottom surface of the conversion box 11 and the side surfaces perpendicular to the bottom surface both include plastic plates, and holes are provided on the plastic plates. The holes can be structures such as circular, square or long strip-shaped. A support net 13 is arranged on the holes. The support net 13 can adopt structures such as a stainless steel wire mesh or a polyester mesh belt. The support net 13 is integrated with the plastic plate during the plastic plate forming process. The support net 13 can permeate air, water and heat, and the plastic plate can block light, providing an artificial natural environment close to the growth of insects, increasing the oxygen content of the material, avoiding anaerobic fermentation, reducing the methane and carbon dioxide emissions during the anaerobic process, and the increase in the oxygen content of the material is beneficial to enhancing the vitality of insects and probiotics, obtaining an increase in biomass and improving the conversion efficiency.

[0031] Furthermore, a retaining edge is arranged inward at the top of the three side surfaces perpendicular to the bottom surface. The retaining edge is parallel to the bottom surface, and the retaining edge is used to block insects from climbing out of the conversion box 11 when the temperature and humidity are not suitable.

[0032] For example, Figure 7As shown in the figure, the multi-layer feeder 2 includes a feeding rack 24, a lifting mechanism 23, a blanking bin 25, a feeding mechanism 26, and multiple material receiving mechanisms. The lifting mechanism 23, the blanking bin 25, and the feeding mechanism 26 are all installed on the feeding rack 24. The blanking bin 25 is arranged between the lifting mechanism 23 and the feeding mechanism 26. The lifting mechanism 23 is used to lift the material to the top of the blanking bin 25, and the multiple material receiving mechanisms are used to guide the material onto the feeding mechanism 26. Both the lifting mechanism 23 and the feeding mechanism 26 adopt belt conveyors. The lifting mechanism 23, the feeding mechanism 26, and the material receiving mechanisms are all controlled by a feeding controller.

[0033] As Figure 7 shown in the figure, the right end of the lifting mechanism 23 is fixed on the elevation block 21, and a retaining wall 22 is arranged at the right end of the lifting mechanism 23. The retaining wall 22 can block the material falling on the lifting mechanism 23 to prevent it from falling.

[0034] As Figure 9 、 10 shown in the figure, the top of the blanking bin 25 is in a flared shape. The top of the blanking bin 25 is connected to the left end of the lifting mechanism 23. An outlet 251 is opened on one side of the blanking bin 25 close to the feeding mechanism 26. The outlet 251 extends from the position of the blanking bin 25 close to the flared structure to the bottom end of the blanking bin 25.

[0035] As Figure 8 shown in the figure, the feeding mechanism 26 includes multiple feeding conveyors 261. The multiple feeding conveyors 261 are arranged corresponding to the multiple conversion boxes 11 for feeding each conversion box 11. The material receiving mechanisms are arranged at the outlet 251. The multiple material receiving mechanisms are arranged corresponding to the multiple feeding conveyors 261. The material receiving mechanism includes a material receiving driving mechanism and a material receiving plate 27. The material receiving plate 27 is provided with a material receiving position and an avoidance position. The material receiving driving mechanism is used to control the material receiving plate 27 to move to the material receiving position to pick up the material falling in the blanking bin 25 and transfer it to the feeding conveyor 261, or control the material receiving plate 27 to move to the avoidance position to avoid the material falling in the blanking bin 25.

[0036] As Figure 8 shown in the figure, the topmost material receiving plate 27 is in the avoidance position, and the other material receiving plates 27 are all in the material receiving position. The material can fall onto the second-layer (from top to bottom) feeding conveyor 261 through the second material receiving plate 27, so as to transfer the material to the corresponding conversion box 11. When it is necessary to feed other conversion boxes 11, the corresponding material receiving plate 27 can be controlled to move to the material receiving position, and the material receiving plate 27 above it moves to the avoidance position, then the feeding of the corresponding conversion box 11 can be realized; the present invention realizes the feeding of multiple conversion boxes 11, and the feeding structure is simple and easy to maintain.

[0037] In some embodiments, the material receiving drive mechanism can be installed on the feeding rack 24 or the drop bin 25 or the feeding mechanism 26. A rotating shaft is set at one end of the material receiving plate 27, and the rotating shaft is arranged close to the feeding conveyor 261. The material receiving drive mechanism controls the rotation of the material receiving plate 27 through the rotating shaft, so that the other end of the material receiving plate 27 turns to the inside of the drop bin 25 to receive the material. Figure 8 The material receiving drive mechanism is not shown in the figure. The material receiving drive mechanism can adopt a reduction motor, which is installed on the feeding rack 24 by bolts. The output end of the reduction motor is connected to one end of the rotating shaft, and the rotating shaft is arranged at the discharge port 251 of the blanking bin 25. The other end of the rotating shaft can be rotatably connected to the blanking bin 25. The rotation of the material receiving plate 27 can be controlled by the reduction motor. When the material receiving plate 27 rotates to the vertical direction, the material receiving plate 27 is in the avoidance position. When the material receiving plate 27 rotates to one end and abuts against the inner wall of the blanking bin 25, the material receiving plate 27 is in the material receiving position.

[0038] In addition, in some embodiments, the receiving plate 27 can also receive or avoid materials through linear motion. For example, the receiving plate 27 is arranged at an angle, and the receiving drive mechanism controls the receiving plate 27 to move horizontally into the material bin 25 until the upper end of the receiving plate 27 abuts the inner wall of the material bin 25. At this time, the receiving plate 27 is in the material receiving position. The receiving drive mechanism controls the receiving plate 27 to move horizontally outside the material bin 25 until the upper end of the receiving plate 27 is flush with the discharge port 251 of the material bin 25. At this time, the receiving plate 27 is in the avoidance position. The receiving drive mechanism can be a cylinder, which can also be mounted on the feeding frame 24. The cylinder can be connected to the receiving plate 27 via an L-shaped connecting rod. The connecting rod is arranged on the side of the material bin 25 near the feeding mechanism 26. One end of the connecting rod is connected to the cylinder, and the other end of the connecting rod is connected to the center of the receiving plate 27, thereby controlling the horizontal movement of the receiving plate 27. However, in this solution, the material will fall onto the connecting rod.

[0039] In some embodiments, the height of the discharge port 251 is equal to the sum of the lengths of the plurality of receiving plates 27 , so that the discharge port 251 can be closed when the plurality of receiving plates 27 rotate to the avoidance position.

[0040] like Figure 8 As shown, when the receiving plate 27 rotates to the avoidance position, it can connect with the receiving plate 27 above it, thereby achieving the closure of the discharge port 251. The closure of the discharge port 251 does not need to be completely sealed, but only needs to ensure that most of the material does not splash out of the discharge bin 25 when falling in the discharge bin 25. In addition, a sealing colloid can also be provided on the edge of the receiving plate 27. The receiving plate 27 contacts the inner wall of the discharge bin 25 and the adjacent receiving plate 27 through the sealing colloid, thereby improving the sealing performance.

[0041] In some embodiments, as Figure 11As shown, the multi-layer conversion rack 1 is arranged on the track 5. The track 5 is parallel to the conveying direction of the feeding conveyor 261. The multi-layer conversion rack 1 is connected with a pushing and pulling mechanism, which is used to control the multi-layer conversion rack 1 to move towards or away from the feeding conveyor 261, so that the materials on the feeding conveyor 261 evenly fall onto the conversion box 11.

[0042] It can be understood that Figure 7 In the state shown, the materials can only be conveyed to one end of the conversion box 11 and accumulate. Therefore, it is necessary to move the conversion box 11 during the conveying process so that the materials evenly fall into the conversion box 11. By setting the track 5 and the pushing and pulling mechanism, the even spreading of the materials in the conversion box 11 can be realized.

[0043] As Figure 11 shown, a placement platform 6 is arranged on the track 5. The bottom of the placement platform 6 is provided with rollers 61, so that the placement platform 6 can move on the track 5. The two sides of the rollers 61 are stuck on both sides of the track 5, so that the rollers 61 are not easily derailed. The multi-layer conversion rack 1 can be installed on the placement platform 6. The multi-layer conversion rack 1 and the placement platform 6 can be fixedly connected by bolts or snap connection. For example, a connecting plate is integrally arranged at the bottom of the multi-layer conversion rack 1, bolt holes are opened on the placement platform 6, and the multi-layer conversion rack 1 can be fixed by fixing the connecting plate on the placement platform 6; or fixing holes are opened on the side of the bottom of the multi-layer conversion rack 1, multiple card holes are opened on the placement platform 6, and an elastic locking pin is arranged on the side of the placement platform 6. After the bottom of the multi-layer conversion rack 1 is inserted into the card hole, one end of the elastic locking pin extends into the card hole and is inserted into the fixing hole of the multi-layer conversion rack 1, so as to fix the multi-layer conversion rack 1. When the multi-layer conversion rack 1 needs to be removed, pull the elastic locking pin so that one end of the elastic locking pin is withdrawn from the fixing hole of the multi-layer conversion rack 1.

[0044] The pushing and pulling mechanism can control the movement of the placement platform 6 by using the principle of gear and rack. For example, the pushing and pulling mechanism includes a reduction motor, which is arranged below the placement platform 6. The output end of the reduction motor is fixedly connected with a gear, and a rack is arranged at the bottom of the placement platform 6. The rack and the gear mesh to generate a linear displacement. During the movement process, it should be moved slowly to ensure the stable movement of the multi-layer conversion rack 1.

[0045] As Figure 12 shown, the material turning mechanism 3 includes a material turning seat 31. A material turning frame 32 is rotatably arranged on the material turning seat 31. An installation position is arranged on the material turning frame 32, and the multi-layer conversion rack 1 can be fixed at the installation position. A turning driving mechanism 33 is arranged on the material turning seat 31, and the turning driving mechanism 33 is used to drive the material turning frame 32 to rotate, so as to turn the multi-layer conversion rack 1 at the installation position. As Figure 15 shown, by setting the material turning mechanism 3, all the materials and insects in all the conversion boxes 11 on the entire multi-layer conversion rack 1 can be poured out simultaneously, improving the work efficiency.

[0046] As shown Figure 14 in the figure, a rotating bearing 311 is provided at the top of the turnover seat 31. The turnover frame 32 is rotatably connected to the turnover seat 31 through the rotating bearing 311. As shown Figure 13 in the figure, the turnover driving mechanism 33 is installed on the outer side of the turnover seat 31. The turnover driving structure can adopt a reduction motor.

[0047] As shown Figure 12 in the figure, a plurality of cross beams 321 are provided on the left and right sides of the turnover frame 32. A locking device 323 is provided on the cross beam 321. After the multi-layer conversion rack 1 is transported onto the turnover frame 32, the multi-layer conversion rack 1 can be locked by the locking device 323, so that the multi-layer conversion rack 1 can rotate together with the turnover frame 32. The locking device 323 can adopt an electromagnetic lock, and corresponding magnets are fixedly provided on the multi-layer conversion rack 1, that is, the multi-layer conversion rack 1 is fixed by magnetic force; the locking device 323 can also adopt an electric telescopic shaft, and corresponding locking holes are opened on the multi-layer conversion rack 1, and one end of the electric telescopic shaft can extend into the locking holes, thereby fixing the multi-layer conversion rack 1.

[0048] As shown Figure 12 in the figure, a plurality of limiting beams 322 are provided on the front side of the turnover frame 32. After the multi-layer conversion rack 1 is transported onto the turnover frame 32, it is abutted against the limiting beams 322, so that the magnets on the multi-layer conversion rack 1 just fit with the electromagnetic lock. At this time, the electromagnetic lock is turned on to fix the multi-layer conversion rack 1.

[0049] The insect-material separation device 4 uses the method of suffocating insects for insect-material separation or uses the mechanical separation method of vibrating screening for insect-material separation.

[0050] In some embodiments, the insect-material separation device 4 uses the method of suffocating insects for insect-material separation. As shown Figure 16 、 17 in the figure, the insect-material separation device 4 includes a flexible covering member 41. The covering member 41 is used to completely cover the insects and materials. A sealing member 43 is provided at the edge of the covering member 41. The sealing member 43 is a flexible structure, such as a flexible rubber sealing strip. The sealing member 43 is used to seal the edge of the covering member 41 with the ground to prevent or reduce the entry of air. A separation cavity 44 is provided inside the covering member 41. A plurality of separation holes 45 are opened at the bottom of the separation cavity 44, so that insects can enter the separation cavity 44 through the separation holes 45, thereby realizing insect-material separation.

[0051] It can be understood that by using the flexible covering member 41 to completely cover the insects and the material, and using the seal 43 to seal the edge of the covering member 41 with the ground, the oxygen in the material will gradually decrease, forcing the insects to drill out of the material and enter the separation chamber 44 through the separation holes 45, thereby separating the insects from the material. Since the covering member 41 is flexible, it is applicable to materials of different thicknesses. And for the insects and materials directly laid flat on the ground or soil, by laying the covering member 41 on the material, the separation of insects from the material can be achieved, with good separation effect and high separation efficiency.

[0052] As Figure 18 shown, the covering member 41 includes an upper covering member 411 and a lower covering member 412. The upper covering member 411 and the lower covering member 412 have the same rectangular structure. Both the upper covering member 411 and the lower covering member 412 include long sides and short sides, and the size of the upper covering member 411 is greater than or equal to that of the lower covering member 412. The upper covering member 411 is made of light-proof materials, such as black and white film, black film, rainproof cloth, etc. As Figure 19 shown, the lower covering member 412 is provided with a plurality of separation holes 456. The lower covering member 412 can adopt a structure such as a mesh cloth, and the aperture of the separation holes 456 is 3 - 7 mm. Only part of the edges of the upper covering member 411 and the lower covering member 412 are connected or not connected, and the unconnected part of the edges of the upper covering member 411 and the lower covering member 412 is set as the discharge port, so that the insects entering the separation chamber can be discharged from the discharge port.

[0053] A support member 42 is arranged between the upper covering member 411 and the lower covering member 412. The support member 42 can adopt low-density materials such as foam, and the upper surface of the support member 42 can be fixed to the upper covering member 411 by glue. The support member 42 can also adopt a pipeline. Suction holes are opened at a position near the top of the pipeline. One end of the support member 42 extends out of the covering member 41 and is connected to an air extraction pump. Through the air extraction pump, the air within the coverage range of the covering member 41 can be quickly discharged, accelerating the reduction rate of oxygen within the coverage range and saving the separation time.

[0054] As Figure 1 shown, based on the above-mentioned three-dimensional bionic conversion system for insect organic waste, the present invention provides a three-dimensional bionic conversion process for insect organic waste, including: S1. Material pretreatment: Using a screw conveyor to convey the material to a stirring and mixing device, and using the stirring and mixing device to stir the material; through pretreatment, the physical, chemical and biological properties of the material such as carbon-nitrogen ratio, temperature, humidity, physical state and microbial inoculum are comprehensively processed. It is suitable for the resource utilization of insects such as maggots, mealworms, black soldier flies, bamboo worms, breadworms, feed worms, protein worms, and superworms.

[0055] S2, feeding: the stirred material is transported to the multi-layer feeder 2, and insect seedlings are added simultaneously when the material is transported to the multi-layer feeder 2. The multi-layer feeder 2 transports the material to each transformation box 11 of the multi-layer transformation rack 1; specifically including: The lifting mechanism 23 continuously lifts the material to the top of the drop bin 25, and the feeding controller controls a certain material receiving drive mechanism so that the material receiving plate 27 corresponding to the material receiving drive mechanism rotates to the material receiving position, and the material receiving plates 27 above the material receiving plate 27 corresponding to the material receiving drive mechanism are all in the avoidance position; the feeding conveyor 261 conveys the material to the corresponding conversion box 11; the push-pull mechanism controls the multi-layer conversion rack 1 to move toward or away from the feeding conveyor 261, so that the material on the feeding conveyor 261 falls evenly onto the conversion box 11, completing the feeding of the conversion box 11 on this layer; repeat the above steps until the feeding of all conversion boxes 11 is completed.

[0056] It should be noted that generally, material should be added starting from the conversion box 11 at the lowest position to avoid the center of gravity of the bogie becoming higher and affecting its stability.

[0057] In addition, the push-pull mechanism can be controlled by the feeding controller, and the multi-layer feeder 2 can also automatically control the feeding time and amount through the feeding controller. Since the conveying speed of the lifting mechanism 23 and the feeding conveyor 261 is known, the feeding time of each conversion box 11 can be calculated according to the conveying speed and the amount of material to be added, that is, the time T0 that each receiving plate 27 is in the receiving position. Specifically: In the initial state, all the receiving plates 27 are in the avoidance position. The lowest conversion box 11 is fed first. The feeding controller controls the lifting device, the feeding conveyor 261, and the push-pull mechanism to open. The material falls directly to the bottom of the drop bin 25 and slides to the lowest feeding conveyor 261. The feeding conveyor 261 conveys the material to the lowest conversion box 11. Under the action of the push-pull mechanism, the multi-layer conversion rack 1 makes the material fall evenly onto the conversion box 11. After T0 time, the feeding controller controls the corresponding feeding drive of the feeding conveyor 261 on the second layer (from bottom to top). The mechanism rotates the receiving plate 27 to the receiving position, and the material will fall onto the receiving plate 27 and be transported to the second layer (from bottom to top) of the conversion box 11 through the second layer of feeding conveyor 261. After T0 time, the feeding controller controls the feeding drive mechanism corresponding to the feeding conveyor 261 of the third layer (from bottom to top) to rotate the receiving plate 27 to the receiving position, and feed the conversion box 11 of the third layer (from bottom to top). Repeat this process until all the conversion boxes 11 are fed. The feeding controller controls the lifting device, feeding conveyor 261, and push-pull mechanism to close.

[0058] S3. Transformation.

[0059] S4. After the conversion is completed, the multi-layer conversion rack 1 is transferred to the turning mechanism 3. The multi-layer conversion rack 1 can be automatically transferred by an unmanned forklift; S5. The turning mechanism 3 pours out all the materials and insects in the conversion box 11; a conveyor belt can be set below the turning mechanism 3 to transport the materials and insects to the position corresponding to the insect material separation process.

[0060] S6, the insect material separation device 4 separates the poured material and insects, specifically including: S61, such as Figure 17 As shown, a cover 41 is laid on the flat material, and the edge of the cover 41 is sealed by a seal 43; wherein the material and insects are spread flat on the hardened ground or field, the thickness of the flat material is controlled to be 5-50 cm, and the ambient temperature is controlled to be 10-50°C; S62: Let it stand for a while, lift the cover, and take out the insects that have entered the separation chamber 44.

[0061] It is understood that since the seal 43 is flexible, it can prevent or reduce the entry of outside air for both undulating hardened ground and land. The oxygen in the material is gradually consumed by insects, and the high oxygen concentration in the separation chamber 44 forces the insects to crawl out and enter the separation chamber 44 through the separation hole 45. Since the upper cover 411 is opaque, it can avoid the separation effect being reduced due to the photophobia of some insects. After standing for 3-15 minutes, the insects can be shaken off from the discharge port to the collection area. If the support member 42 adopts a hollow tube, an air pump is used to discharge the air in the covering area of the cover 41 through the hollow tube. The oxygen concentration in the range close to the hollow tube is higher than the oxygen concentration in other areas, so that insects crawl out of the material and enter the separation chamber 44 through the separation hole 45 and approach the hollow tube. The air pump only needs to pump air for a short time, for example, 5 seconds, so that an oxygen-deficient environment is formed in the covering area of the cover.

[0062] The insect material separation device 4 is primarily used to separate insects and materials spread over a large area on hardened ground or land. By directly covering the insects and materials with a correspondingly sized flexible cover 41, the insects can be manually separated in one go, achieving a separation rate exceeding 99%. The insect material separation device 4 is simple to manufacture, low in cost, and highly efficient.

[0063] In order to achieve a low-cost conversion process, the applicant has developed a conversion system that simultaneously realizes multi-layer material feeding, conversion, and flipping. Through a multi-layer three-dimensional process design, the present invention expands the insect breeding from a planar pond breeding mode to a three-dimensional breeding mode. Compared with the planar pond breeding mode, the three-dimensional breeding mode saves land, is conducive to deodorization treatment, has a simple equipment function process, is fully automated during the breeding process, has high efficiency, low breeding cost, can be scaled up, industrialized, clean and environmentally friendly, and is conducive to industrial promotion.

[0064] The present invention has a reasonable structure, is convenient to operate, occupies a small area, and requires a small amount of labor, and is particularly suitable for large-scale factory breeding. The resource utilization of organic waste eliminates the pollution of livestock and poultry manure, which is of great significance for protecting the ecological environment and promoting the sustainable development of agriculture.
