Description

Technical Field

[0001] This utility model relates to the field of saprophytic insect separation technology, specifically to a saprophytic insect separation device. Background Technology

[0002] Black soldier flies are saprophytic insects that can feed on organic waste such as poultry and livestock manure and household garbage, producing high-value insect biomass. Due to their rapid reproduction, wide range of diets, high absorption and conversion rate, ease of management, low feeding costs, good palatability to animals, and great potential for high-value utilization, they have been widely used in recent years to treat organic waste such as kitchen waste, livestock and poultry manure, and carcasses of diseased and dead livestock and poultry.

[0003] However, for large-scale black soldier fly farming, the insects are used as protein feed, so the black soldier flies need to be separated from the farming material. Currently, manual separation or vibrating screening is usually used for separation. Manual separation is labor-intensive and inefficient, while vibrating screening makes it difficult to completely separate the black soldier flies from the farming material, resulting in low separation efficiency and poor separation effect.

[0004] Chinese utility model patent application CN114223617A discloses a method for separating black soldier flies. This method uses a sealing element to isolate the separation tank from the outside environment, reducing the oxygen concentration in the fly frass. Temperature control forces the black soldier flies to escape from the frass and gather in a mesh. The sealing element is then removed to collect the flies from the mesh, thus separating them from the frass. However, this method requires transferring the farmed black soldier flies along with their frass to the separation tank before separation can occur; it cannot directly separate the flies from the farming area, resulting in low separation efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a saprophytic insect separation device that allows black soldier flies to be separated manually in one operation.

[0006] To solve the above-mentioned technical problems, this utility model provides a saprophytic insect separation device, including a flexible cover for completely covering saprophytic insects and their breeding materials. The cover has a sealing element at its edge to seal the edge of the cover to the ground to prevent or reduce air entry. A separation chamber is provided inside the cover, and multiple separation holes are opened at the bottom of the separation chamber, through which saprophytic insects can enter the separation chamber.

[0007] This invention utilizes a flexible covering to completely cover saprophytic insects and their aquaculture material. A sealing element seals the edges of the covering to the ground, gradually reducing oxygen levels in the aquaculture material. This forces the saprophytic insects to emerge from the material and enter the separation chamber through separation holes, thus separating them from the aquaculture material. Because the covering is flexible, it is suitable for aquaculture materials of varying thicknesses. Furthermore, for saprophytic insects and aquaculture material laid directly on the ground or soil, simply laying the covering on top of the material achieves effective and efficient separation. In addition, for large areas of saprophytic insects and aquaculture material laid on the ground or soil, a larger covering can be made to complete the separation in one go. The flexible covering is also lightweight, allowing for easy manual lifting. With existing technology, the saprophytic insects and aquaculture material must be placed into the separation tank multiple times for sequential separation.

[0008] Furthermore, the cover includes an upper cover and a lower cover, and a support member is provided between the upper cover and the lower cover. The support member supports the upper cover and the lower cover apart, so that the separation cavity is formed between the upper cover and the lower cover, and the separation hole is formed on the lower cover.

[0009] The cover of this utility model consists of two layers, namely an upper cover and a lower cover. By setting a support, the upper cover and the lower cover are separated and form a certain space, namely a separation cavity. The oxygen content in the separation cavity is high, which will attract saprophytic insects to gather in the separation cavity. The support can be a block structure or a strip structure. The upper and lower surfaces of the support can be glued to the upper cover.

[0010] Furthermore, the edges of the upper and lower covers are only partially connected or not connected, and the unconnected edges of the upper and lower covers are set as discharge outlets, so that saprophytic insects entering the separation chamber can be discharged from the discharge outlets.

[0011] This invention features a discharge outlet, which allows saprophytic insects to gather in the separation chamber. By lifting the cover, rotating and shaking the cover, the saprophytic insects can be shaken out from the discharge outlet, making the operation convenient.

[0012] Furthermore, the cover is rectangular (other shapes are also possible, but lack operational convenience), the support is elongated, the support is parallel to the width direction of the cover, and multiple supports are arranged along the length direction of the cover, thereby dividing the upper cover and the lower cover into multiple separation cavities, and the outlet is located on the long side of the cover.

[0013] This invention uses multiple elongated support members to divide the upper and lower cover into multiple separation chambers. After saprophytic insects gather in each separation chamber, they can be shaken out from the discharge port along the elongated support members, thus avoiding the difficulty of shaking out the saprophytic insects due to obstruction by the support members.

[0014] Furthermore, the upper cover is made of an opaque material.

[0015] This invention avoids the poor separation effect caused by the black soldier fly's aversion to light by using an opaque material for the upper cover.

[0016] Furthermore, the lower cover is mesh-like, and the diameter of the separation hole is 3-7 mm.

[0017] Furthermore, the seal is a flexible sealing structure to adapt to ground undulations.

[0018] Furthermore, the support includes a hollow tube, one end of which extends out to a cover and is connected to a vacuum pump.

[0019] This invention makes the sealing element flexible, which is convenient to adapt to uneven ground and fields.

[0020] Furthermore, suction holes are provided on both sides of the hollow tube near the top.

[0021] Furthermore, a pull cord or pull ring may be provided at the corners of the cover.

[0022] The beneficial effects of this invention are as follows: This invention utilizes a flexible covering to completely cover saprophytic insects and their aquaculture materials, and uses a sealing element to seal the edges of the covering to the ground. The oxygen in the aquaculture materials gradually decreases, forcing the saprophytic insects to emerge from the materials and enter the separation chamber through the separation holes, thus separating the saprophytic insects from the aquaculture materials. Because the covering is flexible, it is applicable to aquaculture materials of varying thicknesses. Furthermore, for saprophytic insects and aquaculture materials laid directly on the ground or soil, simply laying the covering on top of the aquaculture materials achieves effective and efficient separation. In addition, for large areas of saprophytic insects and aquaculture materials laid on the ground or soil, a larger covering can be made to complete the separation in one go. The flexible covering is also lightweight, allowing for easy manual lifting. With existing technology, the saprophytic insects and aquaculture materials must be placed into the separation tank multiple times for sequential separation. Attached Figure Description

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figure 1 , 2 As shown, this embodiment provides a saprophytic insect separation device, including a flexible upper cover 1 and a lower cover 2. The upper cover 1 and lower cover 2 have identical rectangular structures, each including a long side and a short side. The size of the upper cover 1 is greater than or equal to that of the lower cover 2. The upper cover 1 is made of an opaque material, such as a black and white film, a black film, or a rainproof cloth. Figure 4 As shown, the lower cover 2 is provided with multiple separation holes 6. The lower cover 2 can be made of mesh or other structures, and the diameter of the separation holes 6 is 3-7mm.

[0030] like Figure 1 , 2 As shown, multiple support members 3 are provided between the upper cover 1 and the lower cover 2. The support members 3 support the upper cover 1 and the lower cover 2, forming a separation cavity 5 between them. The separation cavity 5 communicates with the outside through a separation hole 6. The support member 3 is elongated, with its length equal to the width of the upper cover 1. The support member 3 is arranged parallel to the width direction of the cover, and multiple support members 3 are evenly arranged along the length direction of the upper cover 1 to form multiple separation cavities 5. The support members 3 can be made of low-density materials such as foam, and their upper surfaces can be fixed to the upper cover 1 using adhesives or similar materials.

[0031] Alternatively, the support component 3 can be a hollow tube, with one end extending into a cover and connected to an air pump. The hollow tube and air pump can be connected using a quick-connect device. By using the air pump and hollow tube to expel air from the area covered by the upper cover 1, the oxygen reduction rate in the covered area is accelerated, saving one-third of the separation time. The hollow tube can be used for suction at its end, or the end of the hollow tube can be sealed, with multiple suction holes opened on the tube wall for suction. These suction holes are arranged near the top of the hollow tube.

[0032] like Figure 1 , 3 As shown, a sealing element 4 is fixedly provided around the edge of the upper cover 1. The sealing element 4 is used to seal the edge of the cover to the ground to prevent or reduce air ingress. In this embodiment, the sealing element 4 is a flexible sealing structure to adapt to the ground. The sealing element 4 can be a flexible rubber sealing strip, which can enhance the strength and durability of the upper cover. Alternatively, the sealing element 4 can be provided without a ring, but rather short strip-shaped sealing elements 4 can be spaced along the edge of the upper cover 1, which only needs to reduce air ingress.

[0033] In order to facilitate the discharge of black soldier flies that have entered the separation chamber 5, in this embodiment, the short sides of the upper cover 1 and the lower cover 2 can be fixedly connected as one piece, while the long sides of the upper cover 1 and the lower cover 2 are separated, thereby forming an outlet. The black soldier flies that have entered the separation chamber 5 can be shaken out along the long side of the upper cover 1 and the lower cover 2 under the guidance of the support 3.

[0034] In this embodiment, pull ropes or pull rings are provided at the four corners of the upper cover 1. Since the saprophytic insect separation device is lightweight, it can be lifted directly by manpower using the pull ropes or pull rings.

[0035] This embodiment uses the black soldier fly as an example. The method for separating black soldier flies using this saprophytic insect separation device includes:

[0036] S1, such as Figure 2 , 3 As shown, the black soldier flies and the breeding material 7 in the breeding area are spread evenly on the hardened ground or field, with the spreading thickness controlled at 5-50cm and the ambient temperature controlled at 10-50℃; the breeding material can be chicken manure, pig manure, kitchen waste, etc.

[0037] S2. A cover is laid on the flat breeding material 7. The edges of the cover are sealed by the sealing element 4. Since the sealing element 4 is flexible, it can prevent or reduce the entry of outside air into the breeding material 7 for hardened ground and soil with uneven surfaces.

[0038] S3. The oxygen in the culture material 7 is gradually consumed by black soldier flies, while the oxygen concentration in the separation chamber 5 is high, which will force the black soldier flies to crawl out of the culture material 7 and enter the separation chamber 5 through the separation hole 6. Since the upper cover 1 is opaque, it can avoid the separation effect from deteriorating due to the black soldier flies' aversion to light. After standing for 3-15 minutes, use a rope or pull ring to manually lift the two short sides of the cover and rotate it with the axis of the cover parallel to the long side as the rotation axis. This will shake the saprophytic insects from the discharge outlet to the collection area.

[0039] If the support 3 is made of hollow tube, an air pump is used to exhaust the air in the covered area of ​​the cover through the hollow tube. The oxygen concentration near the hollow tube is higher than that in other areas, which causes the black soldier fly to crawl out of the breeding material 7 and enter the separation chamber 5 through the separation hole 6 and approach the hollow tube. The air pump only needs to pump air for a short time, such as 5 seconds, so that an oxygen-deficient environment is formed in the covered area of ​​the cover.

[0040] This saprophytic insect separation device is mainly used for separating saprophytic insects and aquaculture materials 7 that are spread over a large area on hardened ground or soil. A flexible covering of the corresponding size is directly applied, and black soldier flies can be separated manually in one go, achieving a separation rate of over 99%. This saprophytic insect separation device is simple to manufacture, low in cost, and highly efficient, making it suitable for large-scale black soldier fly farming. Furthermore, it is also applicable to saprophytic insects with similar characteristics to black soldier flies.

[0041] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
