Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically a gas conveying pipeline for insect breeding. Background Technology

[0002] Maggots are a type of insect. Current maggot farming generally uses kitchen waste as a substrate for maggot growth. This not only renders the waste harmless but also accelerates the growth of maggots. However, maggots need an environment with suitable humidity, temperature, and oxygen concentration to grow. In this environment, maggots will grow rapidly, and at the same time, kitchen waste will decompose and rot quickly, emitting various unpleasant odors.

[0003] A search revealed CN208581728U, which discloses an air treatment device for fly larvae breeding beds. This device includes: a breeding bed, a gas input device, a gas extraction device, and a gas treatment device. The breeding bed includes a frame and a multi-layer breeding conveyor belt mounted on the frame. The gas input device has an air delivery pipe, which includes a main delivery pipe and branch delivery pipes. The main delivery pipe is located on one side of the breeding bed frame. The branch delivery pipes are fixed to the upper part of the breeding conveyor belt and are evenly arranged. An air outlet is located at the lower part of the branch delivery pipes, facing the breeding conveyor belt. The gas extraction pipe is located on the other side of the breeding bed frame. This invention's gas input and gas extraction devices can replace the surrounding air of the breeding conveyor belt and extract waste generated by fly larvae growth, which is then adsorbed using activated carbon. This avoids the direct emission of odorous gases into the atmosphere, preventing environmental pollution.

[0004] However, in practical applications, it is necessary to ensure that the oxygen content, temperature and humidity in different areas of the fly larvae breeding space where the breeding conveyor belt is located are relatively stable. If the temperature difference, humidity difference and oxygen content difference between different areas are large, it will cause the fly larvae to crawl around randomly and affect their normal growth.

[0005] Existing technology uses branch conveyor pipes to deliver gas above the breeding conveyor belt. When the gas is discharged from the branch conveyor pipe, it is easy for the gas to accumulate directly in front of the branch conveyor pipe, making it difficult to maintain stable temperature, humidity and oxygen concentration above the breeding conveyor belt, which in turn affects the normal growth of fly larvae. Therefore, we need a gas delivery pipe for insect breeding. Utility Model Content

[0006] The purpose of this invention is to provide a gas delivery pipeline for insect farming, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas conveying pipeline for insect breeding, comprising multiple pipeline units, each pipeline unit including a straight pipe, a tee pipe, a connecting pipe, and a gas nozzle. The upper end of the tee pipe is provided with a first interface, the lower end of the tee pipe is provided with a second interface, and the side of the tee pipe is provided with an inclined third interface. The first and second interfaces can be fitted and snapped together with the end of the straight pipe, the third interface can be fitted and snapped together with the tail of the connecting pipe, the gas nozzle can be fitted and snapped together with the head of the connecting pipe, and the surface of the gas nozzle is provided with a strip-shaped exhaust port.

[0008] Preferably, the gas nozzle includes an installation pipe that can fit into the connecting pipe, a bent plate, and two trapezoidal plates. The bent plate is a steel plate with curved ends and a flat middle. The trapezoidal plates are fixedly welded to both sides of the bent plate, and a gap is left between the two trapezoidal plates. The installation pipe is fixedly connected to the middle of the bent plate and passes through the bent plate.

[0009] Preferably, the inner walls of the first interface, the second interface, and the third interface are all fixedly connected with sealing sleeves.

[0010] Preferably, the tee pipe includes a first branch pipe and a second branch pipe, and an adjustment mechanism for adjusting the orientation of the third interface is provided between the first branch pipe and the second branch pipe. The adjustment mechanism includes a limiting ball sleeve, a steering ball tube, two annular anti-slip seats, two threaded rods and two locking nuts. The limiting ball sleeve is fixedly connected to the end of the first branch pipe, the steering ball tube is fixedly connected to the end of the second branch pipe, and the steering ball tube is rotatably connected to the inside of the limiting ball sleeve. The two threaded rods are symmetrically fixedly connected to both sides of the steering ball tube, and the threaded rods penetrate to the outside of the limiting ball sleeve. The annular anti-slip seats are sleeved on the outside of the threaded rods and fixedly connected to the limiting ball sleeve. The locking nuts are threadedly connected to the threaded rods.

[0013] Beneficial effects

[0014] This utility model provides a gas conveying pipeline for insect breeding, which has the following beneficial effects:

[0015] 1. This gas delivery pipeline for insect breeding, by setting up multiple pipeline units and using the interlocking connection between the straight pipe and the first and second interfaces, can combine multiple pipeline units to adapt to breeding on conveyor belts of different lengths, thus improving adaptability. Moreover, by setting up connecting pipes and gas nozzles, the gas in the straight pipe can be evenly discharged from the strip exhaust port. Compared with the existing technology, this effectively avoids gas accumulation in front of the branch delivery pipe, thereby facilitating the maintenance of stable temperature, humidity and oxygen concentration above the breeding conveyor belt, which provides convenience for the normal growth of fly larvae.

[0016] 2. This gas delivery pipe for insect breeding, by setting an adjustment mechanism, allows the rotating ball tube to be easily rotated after the locking nut is loosened, thereby adjusting the orientation of the second branch pipe and then the orientation of the third interface, so as to change the orientation of the gas nozzle. Tightening the locking nut can fix the limiting ball sleeve and the rotating ball tube relatively, which facilitates the fine adjustment of the exhaust direction of the strip exhaust port, thereby improving the ease of use.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figure 1-3 This utility model provides a technical solution: a gas conveying pipeline for insect breeding, comprising multiple pipeline units 1. Each pipeline unit 1 includes a straight pipe 2, a tee pipe 3, a connecting pipe 4, and a gas nozzle 5. The upper end of the tee pipe 3 is provided with a first interface 6, the lower end of the tee pipe 3 is provided with a second interface 7, and the side of the tee pipe 3 is provided with an inclined third interface 8. The first interface 6 and the second interface 7 can be fitted and snapped together with the end of the straight pipe 2, the third interface 8 can be fitted and snapped together with the tail of the connecting pipe 4, the gas nozzle 5 can be fitted and snapped together with the head of the connecting pipe 4, and the surface of the gas nozzle 5 is provided with a strip-shaped exhaust port 9.

[0024] The gas nozzle 5 includes an installation pipe 10 that can fit into the connecting pipe 4, a bending plate 11, and two trapezoidal plates 12. The bending plate 11 is a steel plate with curved ends and a flat middle. The trapezoidal plates 12 are fixedly welded to both sides of the bending plate 11, and a gap is left between the two trapezoidal plates 12. The installation pipe 10 is fixedly connected to the middle of the bending plate 11 and passes through the bending plate 11. By setting multiple pipe units 1, and using the straight pipe 2 to fit and snap into the first interface 6 and the second interface 7, multiple pipe units 1 can be combined to adapt to different lengths of conveyor belts for breeding, thus improving adaptability. Moreover, by setting the connecting pipe 4 and the gas nozzle 5, the gas in the straight pipe 2 can be evenly discharged from the strip exhaust port 9. Compared with the prior art, this effectively avoids the gas from accumulating in front of the branch conveyor pipe, thus facilitating the maintenance of stable temperature, humidity, and oxygen concentration above the breeding conveyor belt, which is convenient for the normal growth of fly larvae.

[0025] The inner walls of the first interface 6, the second interface 7, and the third interface 8 are all fixedly connected with sealing sleeves 13. By setting the sealing sleeves 13, leakage at the connection points of the first interface 6, the second interface 7, and the third interface 8 can be effectively prevented.

[0026] Example 2, please refer to Figure 1-4Including Embodiment 1, and based on Embodiment 1, this utility model provides a technical solution: the three-way pipe 3 includes a first branch pipe 14 and a second branch pipe 15. An adjustment mechanism 16 for adjusting the orientation of the third interface 8 is provided between the first branch pipe 14 and the second branch pipe 15. The adjustment mechanism 16 includes a limiting spherical sleeve 17, a steering ball pipe 18, two annular anti-slip seats 19, two threaded rods 20, and two locking nuts 21. The limiting spherical sleeve 17 is fixedly connected to the end of the first branch pipe 14, and the steering ball pipe 18 is fixedly connected to the end of the second branch pipe 15. The steering ball pipe 18 is rotatably connected to the inner side of the limiting spherical sleeve 17. The two threaded rods 20 are symmetrically fixedly connected to the steering ball pipe 18. The threaded rod 20 extends to the outside of the limiting spherical sleeve 17 on both sides. The annular anti-slip seat 19 is sleeved on the outside of the threaded rod 20 and fixedly connected to the limiting spherical sleeve 17. The locking nut 21 is threadedly connected to the threaded rod 20. By setting the adjustment mechanism 16, after loosening the locking nut 21, the rotating ball tube 18 can be rotated easily, thereby adjusting the orientation of the second branch tube 15, and thus adjusting the orientation of the third interface 8, so as to change the orientation of the gas nozzle 5. Tightening the locking nut 21 will press against the annular anti-slip seat 19, which can fix the limiting spherical sleeve 17 and the rotating ball tube 18 relatively, providing convenience for fine-tuning the exhaust direction of the strip exhaust port 9, thereby improving the ease of use.

[0027] The surface of the annular anti-slip seat 19 is provided with multiple anti-slip grooves 22 in an annular array. By setting the anti-slip grooves 22, the rotation of the locking nut 21 after tightening is effectively prevented, which would cause the orientation of the strip-shaped exhaust port 9 to change.

[0028] The surface of the limiting spherical sleeve 17 is symmetrically provided with two movable grooves 23. By setting the movable grooves 23, the rotation angle range of the steering ball tube 18 can be increased.

[0029] Working principle: When the gas delivery pipeline for insect breeding is in use, the straight pipe 2 can be connected to the output end of a blower, oxygen generator, or atomizer. Then, different numbers of pipe units 1 are selected and connected according to the length of the conveyor belt for breeding fly larvae. The first interface 6 is sealed at the tail end using a pipe plug. During operation, the gas will pass from the straight pipe 2 through the tee pipe 3, and then from the tee pipe 3 through the connecting pipe 4 into the gas nozzle 5. The airflow is limited by the bending plate 11 and two trapezoidal plates 12. Then, the gas is evenly discharged through the strip exhaust port 9, so that the gas flows above the breeding conveyor belt. Compared with the existing technology, it effectively avoids the gas from accumulating in front of the branch delivery pipe, thus facilitating the maintenance of stable temperature, humidity, and oxygen concentration above the breeding conveyor belt, which provides convenience for the normal growth of fly larvae.
