Description

Technical Field

[0001] The invention relates to the technical field of organic waste treatment, and in particular to a device for utilizing porous materials to assist in organic waste breeding of black soldier flies. Background Art

[0002] There are many organic wastes in our daily life, such as kitchen waste, vegetable waste, livestock and poultry excrement, and fish and shrimp processing waste. Moreover, since these wastes contain solid-liquid mixtures that require additional space for separation operations, and these wastes are also prone to perishability and fermentation, the processing costs and technical requirements are relatively high.

[0003] Black soldier flies feed on a wide range of food, such as kitchen waste, livestock and poultry manure, rotten fruits and vegetables, wheat bran, rice bran, distiller's grains, bean dregs and other agricultural and sideline products. And the black soldier fly larvae can treat organic waste with the following main advantages: 1. Efficient degradation. Black soldier fly larvae can quickly consume organic matter, degrade the amount of waste, and reduce greenhouse gas emissions. Traditional waste treatment such as landfill will produce greenhouse gases such as methane, and black soldier fly larvae treatment can significantly reduce these emissions. 2. Produce useful by-products. Efficiently degrade this type of organic waste and convert it into organic fertilizer for use in agriculture and other fields, increase resource recycling, and black soldier fly treatment takes up less space, and the maintenance cost is lower than traditional landfill or incineration, thereby saving space and cost. 3. Reduce pollution. Reduce groundwater pollution and air pollution caused by landfill waste. Therefore, there are already a large number of cases of black soldier fly larvae treating organic waste to prove that this is a more environmentally friendly, efficient and sustainable method.

[0004] However, in the existing technology and equipment for treating organic waste with black soldier flies, the mixed breeding area of ​​black soldier fly larvae and organic waste is a simple culture tank. If the space retention rate is to be improved, it can only be improved by simply accumulating the number, which will lead to the stacking of a large amount of organic waste and black soldier fly larvae, resulting in poor living conditions (such as air circulation is difficult, or only the surface black soldier fly larvae are sprayed for cooling, and water is difficult to penetrate into the lower layer, etc.), and it is difficult to continue to ensure a good growth environment. In addition, this method is difficult to ensure that the black soldier fly larvae are evenly distributed in the organic waste, which will inevitably lead to the problem of low processing efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a device for cultivating black soldier flies using porous materials to assist organic matter, so as to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the present invention provides a device for cultivating black soldier flies with organic matter using porous materials as an aid, the device comprising: a feed funnel, a spray unit, a breeding room, a porous material filling area, a removable filtrate blind plate, and a collecting funnel; wherein the top and bottom ends of the breeding room are respectively connected to the feed funnel and the collecting funnel; a porous material filling area is arranged inside the breeding room; a removable filtrate blind plate is arranged at the bottom of the breeding room; the spray unit is arranged in the upper half of the breeding room, and the spray unit is used to spray the filtrate collected by the collecting funnel onto the porous material filling area.

[0007] Optionally, the porous material filled area occupies at least 60% of the volume of the breeding room, and the porous material filled area consists of a plurality of cubic blocks.

[0008] Optionally, the device further comprises: a porous partition;

[0009] Wherein, the porous partition is arranged at the bottom of the breeding room and above the removable filtrate blind plate.

[0010] Optionally, the side length of the cubic block is greater than the hole diameter of the porous partition.

[0011] Optionally, the material of the cubic block includes at least one of the following: porous polyurethane sponge, porous ceramics, porous activated carbon, loofah, and steel wool.

[0012] Optionally, the device further comprises: a stirring device arranged in the porous material filling area, for uniformly mixing the black soldier fly larvae and the organic waste.

[0013] Optionally, the device further comprises: a collecting box disposed below the collecting funnel, for storing the filtrate.

[0014] Optionally, the device further comprises: a temperature baffle connected to the collection box, for determining whether to transport the filtrate according to the temperature of the breeding room.

[0015] Optionally, the device further comprises: a liquid transfer pipe for connecting the temperature baffle and the spray unit, and a water pump arranged on the liquid transfer pipe;

[0016] Wherein, the liquid transfer pipe is used to transport the filtrate; and the water pump is used to provide power for transporting the filtrate.

[0017] Optionally, the device further comprises: a stirring motor connected to the stirring device, for providing power to the stirring device.

[0018] Technical effects and advantages of the present invention:

[0019] 1. The present invention innovatively introduces a large number of small cubes made of porous materials to fill the black soldier fly breeding room. The loose and porous characteristics of the materials make it easy for air to circulate, which can provide sufficient oxygen conditions for the growth of the larvae. The larvae are fully mixed with the organic waste and evenly distributed therein through the stirring device, which maximizes the use of the spatial volume of the black soldier fly breeding room and improves the decomposition efficiency of the organic waste by the black soldier flies.

[0020] 2. The present invention omits the redundant step of separating solids and liquids in the traditional treatment of organic waste by utilizing a combination of a temperature baffle, a water pump and a spraying device. At the same time, while saving the space required by the traditional solid-liquid treatment device of organic waste, the leachate of the organic waste can be directly used to spray and cool the larvae in the black soldier fly breeding room, thereby achieving a liquid circulation effect. In addition, since the breeding room is filled with a large number of small blocks made of loose porous materials, the liquid can also fully penetrate downward, solving the problem of poor larval growth space caused by the traditional technical facilities that simply rely on stacking to improve the treatment efficiency. Therefore, while achieving the purpose of controlling the temperature of the black soldier fly breeding room, a better growth environment is provided for the growth of the larvae.

[0026] In order to solve the shortcomings of the prior art, the present invention discloses a device for cultivating black soldier flies using porous materials to assist organic matter. Figure 1 The device comprises: a feed funnel 1, a spray unit 2, a breeding house 3, a porous material filling area 4, a stirring device 5, a stirring motor 6, a porous partition 7, a removable filtrate blind plate 8, a collecting funnel 9, a collecting box 10, a temperature baffle 11, a water pump 12, and a liquid transfer pipe 13.

[0027] The top and bottom of the breeding house 3 are connected to the feed funnel 1 and the collecting funnel 9 respectively; a collecting box 10 is arranged below the collecting funnel 9, and preferably, a collecting box is fixed at the bottom of the collecting funnel.

[0028] Among them, the temperature baffle 11 connected to the collection box 10 is preferably provided at the bottom of the collection box; the temperature baffle is connected to the spray unit 2 through a liquid transfer pipe 13, and a water pump 12 is provided on the liquid transfer pipe 13; and a spray device 5 is horizontally placed in the upper area of ​​the breeding room 3. Specifically, the temperature baffle can be opened and closed according to the temperature in the breeding room to achieve the purpose of determining whether to allow liquid to pass through. When the temperature baffle is opened, the leachate waste passes through the liquid transfer pipe, and the leachate can be transported to the spray unit through the water pump.

[0029] Among them, a porous partition 7 is fixed at the bottom of the black soldier fly breeding room 3, and the bottom of the porous partition 7 is tightly attached to a detachable filtrate blind plate 8, and the bottom of the detachable filtrate blind plate is connected to a collecting funnel, and a collecting box is fixed at the bottom of the collecting funnel.

[0030] Wherein, a porous material filling area 4 is arranged inside the breeding room 3, and the porous material filling area 4 occupies at least 60% of the space in the black soldier fly breeding room 3. The porous material filling area is composed of a plurality of small cubic blocks, the side length of the cubic blocks should be greater than the hole diameter of the porous partition 7, and the cubic blocks can be selected from at least one of porous polyurethane sponge, porous ceramics, porous activated carbon, loofah, and steel wool, but are not limited thereto.

[0031] A stirring device 5 is transversely fixed in the porous material filling area 4, and the stirring device is connected to a stirring motor 6 outside the breeding room.

[0032] In order to better understand the scheme, the following also provides a method for using a device for cultivating black soldier flies using porous materials to assist organic matter, as follows:

[0033] 1. First, install the removable filtrate blind plate 8, and let the black soldier fly larvae and the solid-liquid mixture of organic waste (such as kitchen waste, etc.) enter the breeding room 3 through the feeding funnel 1 in turn.

[0034] 2. Start the stirring motor 6, and the stirring device 5 starts to work. At this time, the black soldier fly larvae and the organic waste are fully mixed in the small cube area composed of a large amount of porous materials, that is, the porous material filling area 4. Because of its loose and porous characteristics, it can ensure the air flow in the breeding room and allow the liquid to penetrate downward. The stirring device 5 can be stopped after being turned on for a period of time. At this time, the black soldier fly larvae and the organic waste are fully and evenly mixed in the breeding room 3 due to the filling of the porous material and the action of the stirring device, and the liquid in the organic waste penetrates to the lower layer due to gravity.

[0035] 3. The permeated filtrate passes through the porous partition 7 and the removable filtrate blind plate 8 in sequence, and is temporarily stored in the collection box 10 through the collecting funnel 9.

[0036] 4. The temperature baffle 11 is selectively opened according to the temperature conditions in the breeding room 3. When the temperature reaches a certain threshold, the temperature baffle 11 is opened, and the leachate is transported to the spray unit 2 through the liquid transfer pipe 13 due to the action of the water pump 12 and cooled. This process achieves the effect of cooling the breeding room 3 by circulating the waste liquid without solid-liquid separation during feeding.

[0037] 5. After the one-week breeding cycle is completed, the detachable filtrate blind plate 8 is removed, the temperature baffle switch is turned off, and the stirring device 5 is turned on to allow the black soldier fly adults and the organic fertilizer converted from the organic waste to fall into the collection box 10 through the collection funnel 9. In addition, since the cube block is made of porous material, the side length of the cube block is elastic under certain materials, so its side length should be greater than the hole diameter of the porous partition 7 so that it cannot pass through, so as to continue to be recycled in the breeding room 3.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
