Description

Technical Field

[0001] This utility model relates to the field of environmental engineering, specifically to an automatic separation device for black soldier fly sand and pre-pupae. Background Technology

[0002] Black soldier flies are a resource-rich insect currently widely used in the treatment of organic waste, such as kitchen waste. Utilizing black soldier flies to treat organic waste can address the shortage of animal protein sources that hinders the development of the livestock industry. Their excrement can also be transformed into organic fertilizer through substrate processing or composting, achieving the goals of resource recovery, harmless treatment, and volume reduction of organic waste. This provides a new approach for the healthy and sustainable development of my country's circular economy.

[0003] When using organic waste to raise black soldier flies, a large amount of insect waste is produced as the flies feed and grow. This waste is a mixture of black soldier fly excrement, undigested food, and larval excrement. Insect waste is rich in organic matter and nutrients, and after substrate processing or composting, it can be disposed of in the fields, which is beneficial to soil environment improvement and crop growth. Black soldier fly prepupae contain high levels of protein and fat, making them a high-quality protein feed for the aquaculture industry, thus offering economic benefits. Therefore, it is necessary to separate black soldier fly prepupae from insect waste.

[0004] Because black soldier fly larvae vary in size, they are difficult to separate using sieves, and manual separation methods are costly. When feeding black soldier flies with organic waste such as kitchen waste, the overall moisture content of the larvae's sand is high, making it viscous and hindering separation from the pupae. Currently, most experiments using black soldier flies to treat organic waste rely on manual separation, which is labor-intensive and often ineffective. Using existing separation equipment in the aquaculture industry is costly and unsuitable for laboratory use. Therefore, there is an urgent need for a black soldier fly larvae-sand separation device that is easy to assemble, has a simple structure, and can be used in experimental operations to address the issue of high manpower requirements in laboratories and improve the efficiency of larvae-sand separation. Utility Model Content

[0005] To address the problems of low efficiency, easy damage to insect bodies, low automation, and high cost in existing technologies for separating black soldier fly larvae from sand, especially the inapplicability of large-scale aquaculture separation devices when separating a small number of larvae from sand in the laboratory, this utility model aims to provide a black soldier fly larvae-sand separation device and method that is easy to build, simple in structure, low in cost, and can be used in experimental operations, so as to achieve efficient separation of black soldier fly prepupae from larvae-sand, reduce labor costs, and improve experimental efficiency.

[0006] This utility model is achieved through the following technical solution: an automatic separation device for black soldier fly sand and pre-pupae, comprising: a separation box, an insect body collection box, and a filtrate collection box. A separation component is installed inside the separation box. The insect body collection box is placed on the right side of the separation box, and the filtrate collection box is placed in the fixing frame at the bottom of the separation box. The separation box includes an outer shell, a cover plate, a fixing frame, a filtrate plate, and a separation component.

[0007] The top, left, and rear ends of the outer shell are made of a single piece of acrylic sheet, while the front and right ends are open acrylic sheets. Two filter plates are fixed in the middle of the lower side of the outer shell.

[0008] The left, right and rear ends of the fixing frame are fully covered plates, while the front end is left open, and it is combined with the filtrate collection box.

[0009] The filter plate includes a filter plate one and a filter plate two. The filter plate one is provided with three slots. The climbing plate and the filter plate are connected by slot one, slot two and slot three on the filter plate one. The filter plate two is a fixed plate below the filter plate one.

[0010] The sizes of the leakage holes in the first filter plate and the second filter plate are different;

[0011] As an implementation of the device, the separation component includes a climbing plate, a support plate, a circular hole, an angle hole one, an angle hole two, an angle hole three, and a positioning hole. The support plate can be divided into a base plate and a telescopic plate. The telescopic plate can be fixed to the positioning hole on the base plate through the angle hole one, angle hole two, and angle hole three, and the angle of the climbing plate can be adjusted. The climbing plate and the support plate are connected through the circular hole.

[0012] The insect collection box is located at the right end of the separation box and is attached to the support plate. A handle is provided on the outside of the separation box.

[0013] The filtrate collection box is located inside the fixed frame, and its top is attached to the second filtrate plate.

[0014] The beneficial effects of this utility model are as follows: by setting up a separation component, the climbing plate can separate the black soldier fly from the insect sand and allow it to enter the insect body collection box. The residue and filtrate in the insect sand are initially separated by the first filtrate plate. The larger residue will be left on the first filtrate plate, and the smaller residue will be separated by the second filtrate plate. At this time, the black soldier fly enters the insect body collection box, the insect sand remains on the filtrate plate, and the filtrate enters the filtrate collection box, thereby achieving the purpose of efficient separation of the black soldier fly pre-pupa from the insect sand.
