Description

Technical Field

[0001] The utility model relates to the technical field of insect breeding boxes, in particular to an improved breeding box. Background Art

[0002] In modern urban life, a large amount of food waste is generated every day. This waste contains a high concentration of water and organic matter, easily spoiling and producing foul odors. It also pollutes the environment and may even spread pathogens that harm human health. Therefore, effective treatment technologies are needed to reduce the environmental and economic burden of food waste.

[0003] Black soldier flies have a short life cycle and strong reproductive capacity. A female fly can lay about 100 eggs a day, and it only takes 20 days to hatch the next generation. During the breeding process of black soldier flies, black soldier flies can eat processed kitchen waste, and black soldier flies can effectively decompose kitchen waste and convert it into high-value biomass such as oil and protein. Using black soldier flies to treat kitchen waste is an environmentally friendly and economically profitable method.

[0004] The breeding process of black water snakeheads is mainly achieved through corresponding breeding boxes. During the breeding process of black water snakeheads, processed kitchen waste food is put into the breeding trays, and the black water snakehead larvae grow in the breeding trays by eating the processed kitchen waste food. The breeding trays containing food and larvae are stacked and placed inside the breeding boxes.

[0005] It should be pointed out that in the process of breeding black water bulls in breeding boxes, waste gas will be generated, and the waste gas contains ammonia, which produces a bad smell. In order to avoid the accumulation of waste gas affecting the growth of black water bulls, it is necessary to ensure the air quality in the breeding box by supplying fresh air and removing waste gas.

[0006] Among them, the patent number is: ZL202121705566.6, and the patent name is: A Chinese utility model patent for an insect breeding box, which discloses the following technical solutions, specifically: an insect breeding box, including a box body, an air inlet pipe, and an air outlet pipe. A cavity for breeding insects is formed inside the box body, and the air inlet pipe and the air outlet pipe are both connected to the box body. A fan is provided at the air outlet of the air outlet pipe. The fan can be driven to rotate to form a lower air pressure in the box body than the outside world, so that air enters the box body through the air inlet pipe; the air inlet pipe includes a first pipe that is connected to the external fluid, a second pipe and a third pipe that can be fluidically connected to the first pipe, one end of the second pipe and the third pipe is connected to the first pipe, and the other end is connected to the box body; the exhaust port of the second pipe located in the box body decreases from left to right, and the size of the specific exhaust port can be reduced by 3% successively, so that the fresh air is evenly distributed in the box body.

[0007] It should be pointed out that the above-mentioned insect breeding box has the following defects. Specifically, for the breeding method of black water snakehead by stacking breeding trays, the air intake and outlet methods of the above-mentioned insect breeding box cannot effectively discharge the waste gas, that is, there is a problem of insufficient discharge of breeding waste gas. Utility Model Content

[0008] The purpose of the utility model is to provide an improved breeding box to address the deficiencies of the existing technology. The improved breeding box has a novel structural design, sufficient exhaust gas discharge, and can be effectively applied to black water bull aquaculture by stacking breeding trays.

[0009] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0010] An improved breeding box includes a breeding box body in the shape of a rectangular box, a breeding chamber is formed inside the breeding box body, and an air inlet-exhaust assembly is installed at the rear end of the breeding box body;

[0011] The air intake-exhaust assembly includes a rear box body that is fastened to the rear end of the breeding box body. The interior of the rear box body is formed with an air intake chamber and an exhaust chamber that are open to the front and spaced apart on the left and right sides. The outer surface of the rear box body is provided with a box air intake hole and a box air exhaust hole. The box air intake hole is connected to the air intake chamber, and the box air exhaust hole is connected to the exhaust chamber. The rear box body is equipped with an exhaust fan for exhausting air outward at the position of the box air exhaust hole.

[0012] A vertically arranged middle partition is installed inside the breeding box, the rear end of the middle partition is connected to the rear side wall of the breeding box, and the front end of the middle partition is separated from the front side wall of the breeding box. The middle partition divides the breeding chamber into a first straight airflow channel, an airflow turning channel, and a second straight airflow channel that are connected in sequence along the airflow direction;

[0013] The rear side wall of the breeding box is provided with a rear side wall air inlet hole for connecting the air inlet chamber and the first air flow straight channel, and a rear side wall exhaust hole for connecting the air exhaust chamber and the second air flow straight channel; the rear side wall air inlet hole is composed of a number of air inlet long holes arranged in sequence from top to bottom and each of which is a horizontal long strip.

[0014] The outer surface of the rear box body is provided with two box body exhaust holes spaced apart from each other, and the rear box body is provided with an exhaust fan at each box body exhaust hole position;

[0015] The rear side wall of the breeding box body is provided with two rear side wall exhaust holes which are spaced apart from each other, and the two rear side wall exhaust holes are aligned with the two box body exhaust holes.

[0017] Wherein, a rolling door is installed at the front end of the breeding box.

[0018] The breeding box includes a main steel frame and an insulation board fixed on the main steel frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects, specifically:

[0020] 1. Since the air inlet holes on the rear side wall are composed of a number of air inlet holes that are arranged in sequence from top to bottom and are in the shape of horizontal strips, when in use, the air inlet holes are aligned with the gaps between the trays of the tray stack, that is, the air flow will directly blow to the black water bull breeding area of the breeding tray. The exhaust gas generated during the breeding of black water bulls can be quickly blown away from the breeding area of the breeding tray along with the air flow, thereby ensuring that the exhaust gas generated during the breeding of each breeding tray can be discharged in a timely and sufficient manner;

[0021] 2. The airflow flows unidirectionally along the first straight airflow channel, the airflow turning channel and the second straight airflow channel. This orderly and stable airflow can fully discharge the exhaust gas in the breeding chamber of the breeding box;

[0022] 3. Therefore, the utility model has the advantages of novel structural design and sufficient exhaust gas discharge, and can be effectively applied to black water bull aquaculture by stacking aquaculture trays. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present invention will be described below in conjunction with specific implementation methods.

[0030] Example 1, as Figures 1 to 3 As shown, an improved breeding box includes a breeding box body 1 in the shape of a rectangular box, a breeding chamber is formed inside the breeding box body 1, and an air intake-exhaust component 2 is installed at the rear end of the breeding box body 1.

[0031] Among them, such as Figures 1 to 3 As shown, the air intake-exhaust assembly 2 includes a rear box 21 that is fastened to the rear end of the breeding box 1. The interior of the rear box 21 is formed with an air intake chamber 22 and an exhaust chamber 23 that are open to the front and arranged at intervals on the left and right. The outer surface of the rear box 21 is provided with a box air intake hole 24 and a box exhaust hole 25. The box air intake hole 24 is connected to the air intake chamber 22, and the box exhaust hole 25 is connected to the exhaust chamber 23. The rear box 21 is equipped with an exhaust fan 26 for exhausting air outward at the position of the box exhaust hole 25.

[0032] Further, such as Figure 2 and Figure 3 As shown, the interior of the breeding box 1 is equipped with a vertically arranged middle partition 11, the rear end of the middle partition 11 is connected to the rear side wall of the breeding box 1, and the front end of the middle partition 11 is separated from the front side wall of the breeding box 1. The middle partition 11 divides the breeding chamber into a first airflow straight channel 12, an airflow turning channel 13, and a second airflow straight channel 14 that are connected in sequence along the airflow direction. Specifically, as Figure 3 As shown, the airflow directions of the first straight airflow channel 12 and the second straight airflow channel 14 are completely opposite.

[0033] Furthermore, Figure 2 and Figure 3 As shown, the rear side wall of the breeding box 1 is provided with a rear side wall air inlet hole for connecting the air inlet chamber 22 and the first air flow straight channel 12, and a rear side wall exhaust hole for connecting the air exhaust chamber 23 and the second air flow straight channel 14; the rear side wall air inlet hole is composed of a number of air inlet long holes 15 arranged in sequence from top to bottom and in the shape of horizontal long strips.

[0034] like Figure 2 and Figure 3 As shown, a plurality of tray stacks 3 are placed in the first straight airflow channel 12 and the second straight airflow channel 14 respectively. The tray stacks 3 are formed by stacking a plurality of culture trays 31, and each culture tray 31 is used to place food and seawater insect seedlings. Among them, for each tray stack 3, an inter-disc gap 32 for airflow to pass through is formed between two adjacent culture trays 31.

[0035] When the improved breeding box of the first embodiment of the present invention is in use, fresh air enters the air inlet chamber 22 through the box air inlet hole 24 of the rear box body 21, and the fresh air entering the air inlet chamber 22 enters the first air flow straight channel 12 through the rear side wall air inlet hole. The air flow entering the breeding chamber flows along the first air flow straight channel 12, the air flow turning channel 13 and the second air flow straight channel 14, and finally enters the exhaust chamber 23 through the rear side wall exhaust hole. The exhaust gas entering the exhaust chamber 23 is discharged under the action of the exhaust fan 26.

[0036] It should be pointed out that since the air inlet holes on the rear side wall are composed of a number of air inlet long holes 15 arranged in sequence from top to bottom and are respectively in the form of horizontal long strips, when in use, each air inlet long hole 15 is aligned with the inter-disc gap 32 of the disk stack 3, that is, the air flow will blow directly to the black water bull breeding area of the breeding disk 31, and the exhaust gas generated during the breeding of the black water bull can be quickly blown away from the breeding area of the breeding disk 31 with the air flow, thereby ensuring that the exhaust gas generated during the breeding of each breeding disk 31 can be discharged in a timely and sufficient manner.

[0037] In addition, the airflow flows unidirectionally along the first airflow straight channel 12, the airflow turning channel 13 and the second airflow straight channel 14. The orderly and stable airflow can fully discharge the exhaust gas in the breeding chamber of the breeding box 1.

[0038] In summary, it can be seen that, through the above structural design, the improved breeding box of the first embodiment has the advantages of novel structural design and sufficient exhaust gas discharge, and can be effectively applied to black water bull aquaculture by stacking the breeding trays 31.
