Description

Technical Field

[0001] This utility model relates to an active insect separation device, which belongs to the category of insect separation equipment. Background Technology

[0002] Insects can utilize organic waste and leftover crops as food. For example, black soldier fly larvae feed on decaying organic matter and animal feces, converting these wastes into nutrients, maximizing resource utilization, and reducing waste disposal costs and environmental pollution. After insect rearing, the insects and their excrement need to be screened and collected, with the collected adult insects used as protein feed. However, due to the complexity of organic waste materials and the uneven particle size distribution of the material after insect consumption, there are some insect excrement and large-diameter lightweight particles. These large-diameter lightweight particles, such as plastics and fibers, are similar in size to the insect bodies. Mechanical screening methods such as drum screens, vibrating screens, or air separators are insufficient to efficiently separate the insect bodies, excrement, and debris. Due to incomplete separation, manual intervention is required, using methods such as piling up and scraping the material to separate the insect bodies, resulting in low overall separation efficiency. Currently, to solve this problem, some studies utilize insects' sensitivity to environmental temperature and their aversion to light, using heating or light to induce larvae to crawl out of the insect-feed mixture on their own. However, the structural design is complex, the separation time is long, and the separation is incomplete. Utility Model Content

[0003] This invention provides an active insect separation device that solves the problems of existing separation devices that use heating or light, such as complex structural design, long separation time, and incomplete separation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An active insect separation device includes a box with a large upper opening and a small lower opening. The box is equipped with a heating mechanism. The inner wall of the box is wholly or partially equipped with a corrugated insect guide plate. The box is provided with an insect outlet hole, which is located at the top of the corrugated insect guide plate.

[0006] Furthermore, preferably, the top of the box is provided with an insulated cover.

[0007] Furthermore, preferably, the inside of the box is equipped with an insect-collecting net.

[0008] Furthermore, preferably, an insect-collecting mechanism is provided below the insect outlet hole.

[0009] Furthermore, preferably, the insect collecting mechanism is an insect collecting hopper or an insect collecting conveyor belt.

[0010] Furthermore, preferably, the heating mechanism is a water bath heating mechanism, and the bottom of the box is installed together with the water bath heating mechanism.

[0011] Furthermore, preferably, the water bath heating mechanism includes a water tank, a heating rod, and a temperature control switch.

[0012] Furthermore, preferably: an insulation board is provided on the outside of the box at the position where the wavy insect guide plate is not provided inside.

[0013] Furthermore, preferably: the high-temperature insect separation device further includes a lifting mechanism, and the heat-insulating cover and / or the insect-collecting net are installed together with the lifting mechanism.

[0014] Furthermore, preferably, the housing is installed together with the lifting mechanism.

[0015] The beneficial effects of this utility model are:

[0016] The separation device of this invention raises the temperature inside the chamber (e.g., 40-50°C) through a heating mechanism. Insects, due to their attraction to oxygen or avoidance of high temperatures, actively migrate to the lower-temperature area. For example, black soldier fly larvae will actively move towards the surface or vents at high temperatures. The top of the wavy insect guide plate of this device, acting as a low-temperature zone (or near the vents), guides the insects to concentrate at the exit hole. Compared to traditional sieving or manual sorting, this device utilizes the insects' instinctive behavior to reduce mechanical damage and improve separation efficiency.

[0017] The wavy insect guide plate design increases the movement path and contact area of ​​insects within the enclosure. Its wavy structure increases the friction between the insects and the inner wall of the enclosure, making them easier to guide during crawling. The wavy guide plate guides them towards the exit hole at the top, facilitating the concentrated collection of target insects. Simultaneously, the tortuous path of the wavy guide plate increases the time insects spend inside the enclosure, allowing the heating mechanism to more effectively filter the insects by temperature, making it easier to separate debris carried on the insects' surfaces and improving the separation efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are also described.

[0028] Example 1

[0029] like Figure 1 and 2 As shown, an active insect separation device includes a box 1 with a large upper opening and a small lower opening. The box 1 is mainly used for storing materials to be separated. Its vertical inclination is sufficient to allow insects to climb to the top of the box 1 without rolling down. The shape can be square, rectangular, or circular, depending on the actual situation. This embodiment uses a square box 1. The box in this embodiment includes a trapezoidal main body with a rectangular base at the bottom.

[0030] The box is equipped with a heating mechanism, which mainly provides a heat source for insect separation. The heating mechanism can be selected from various options, such as an electric heating rod 2, a hot water pipe, or a hot air pipe, to provide heat. The heating mechanism can be installed on the box according to actual needs. Its specific location within the box depends on the actual separation requirements; for example, it can be installed at the bottom, sides, or all around the box. In this embodiment, it is installed at the bottom of the box. In this embodiment, the heating mechanism uses an electric heating rod 2, which is installed inside the rectangular bottom.

[0031] The inner wall of the box is provided with a wavy insect guide plate 3 in whole or in part, and the box is provided with an insect outlet hole 4, which is located at the top of the wavy insect guide plate 3.

[0032] The wavy insect guide plate 3 includes alternating crests and troughs, and can be V-shaped, U-shaped, or sinusoidal, etc. This embodiment uses a V-shaped structure. The wavy insect guide plate 3 is integrally molded and laid along the inner side wall of the box. The laying area and position of the wavy insect guide plate 3 can be selected according to the actual situation. For example, the inner wall of the box may be entirely or partially covered with the wavy insect guide plate 3. In this embodiment, the wavy insect guide plate 3 is laid on the two trapezoidal sides of the trapezoidal box.

[0033] The operation process of this embodiment is as follows: the material containing insects is placed into the box, the heating mechanism is turned on, and the temperature of the material rises. In order to avoid the harm of high temperature, the insects crawl out of the material, crawl along the top of the wavy insect guide plate 3, and fall out of the insect outlet 4 and are collected, thus completing the separation of insects.

[0034] The wavy structure of the wavy insect guide plate 3 increases the friction between the insects and the inner wall of the box, making it easier to guide the insects during crawling. The wavy guide plate 3 guides them towards the outlet hole 4 at the top, which is beneficial for the concentrated collection of target insects. At the same time, the tortuous path of the wavy guide plate 3 can also increase the time that the insects stay in the box, making the temperature screening effect of the heating mechanism more effective and making it easier to separate the debris carried on the insect surface, thus improving the separation effect.

[0035] Example 2

[0036] like Figure 3-5 As shown, it is basically the same as Example 1, except that:

[0037] The top of the chamber is equipped with an insulation cover 5, which mainly serves to quickly heat up and keep the temperature, thereby improving separation efficiency and reducing energy consumption.

[0038] The box contains an insect-collecting net 6, primarily designed to improve insect separation efficiency. Insects take a considerable amount of time to move outwards; the net 6 allows insects in the center to easily escape, and these insects are then manually or automatically removed from the net and poured into the collection box. The insect-collecting net 6 is typically made of elastic plastic. When installed, it is taut and fixed to the box, enlarging the mesh to facilitate insects crawling out of the material and into the net. When retracted, the mesh shrinks, effectively preventing insects from falling off.

[0039] Below the insect outlet 4 is an insect collecting mechanism. This mechanism can be a fixed mechanism such as an insect collecting hopper 9, or an automatic insect collecting mechanism such as a conveyor belt, or a combination of both. A screening mechanism can even be installed to separate the larvae.

[0040] The heating mechanism is a water bath heating mechanism 8. Using this mechanism ensures stable heating and cooling, effectively preventing damage to insects from rapid temperature increases. The bottom of the box is installed together with the water bath heating mechanism 8.

[0041] The water bath heating mechanism 8 is a conventional heating mechanism, which generally includes a water tank 83, a heating rod 82, and a temperature control switch 81, etc.

[0042] To further improve separation efficiency, an insulation board 7 is installed on the outside of the box at the location where there is no corrugated insect guide plate 3 inside. This can effectively reduce heat loss and improve the separation effect.

[0043] Example 3

[0044] like Figure 6 and 7 As shown, it is basically the same as in Embodiment 1, except that the high-temperature insect separation device of this utility model also includes a lifting mechanism. The function of the lifting mechanism is to lift any one or more of the heat preservation cover 5, the insect collecting net 6 and the box as needed, change their distance, and place them in a better position to achieve a better separation effect.

[0045] For example, lifting the insulation cover 5 is used to control the feeding and temperature inside the box, making the temperature inside the box more suitable for the separation of insects;

[0046] The insect-collecting net 6 is used to collect insects from the insect-collecting net 6;

[0047] The enclosure was raised to change the contact area between the enclosure and the water bath, and the temperature was adjusted to make it more suitable for insect separation.

[0048] The lifting mechanism can be set as needed. In this embodiment, two lifting mechanisms are set up, which are used to lift the heat insulation cover 5 and the insect collection net 6 respectively.

[0049] The lifting mechanism can be a conventional lifting mechanism, such as a rope lifting mechanism, chain lifting mechanism, hydraulic lifting mechanism, or rack and pinion lifting mechanism, etc., selected according to actual needs. In this embodiment, the lifting mechanism includes two columns 13, each with a slide rail 14 and a slider 12. The slider 12 is installed within the slide rail 14 and has a power mechanism 10. The slider 12 is fixed to the insulation cover 5 or the insect-collecting net 6 by a pull rope 11.

[0050] This embodiment can effectively adjust the distance between the heat preservation cover 5, the insect collection net 6 and the box by setting a lifting mechanism, so that the insect separation is in a good state and helps to improve the separation efficiency.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
