Description

Technical Field

[0001] This utility model relates to the technical field of oxygenation equipment, and more specifically, to a multi-branch portable shrimp and fish fry packaging and oxygenation device. Background Technology

[0002] In the aquaculture and logistics industry, the short- to medium-distance or long-distance transport of live aquatic animals such as shrimp larvae and fish fry is a crucial link in ensuring aquaculture production and market supply. Because these organisms are highly sensitive to dissolved oxygen levels, temperature, and cleanliness in the water, their survival rate is closely related to the oxygen supply conditions during transport. Therefore, a common practice is to use oxygen-filled packaging bags for repackaging and to maintain the oxygen concentration inside the bags using aeration equipment to ensure the survival of the larvae during transfer.

[0003] The oxygen filling and dispensing equipment widely used in the industry typically consists of a high-pressure oxygen cylinder, a pressure reducing valve, a gas delivery hose, and a multi-head gas distribution manifold.

[0004] Currently, in the actual use of traditional oxygen filling and dispensing equipment, traditional equipment is not conducive to multiple people working at the same time in centralized filling operations, and the pressure inside the oxygen cylinder is not easy to control, lacking safety features.

[0005] Therefore, in view of this, we have studied and improved the existing structure to provide a multi-branch portable shrimp and fish fry packaging and aeration device, in order to achieve a more practical purpose. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a multi-branch portable shrimp and fish fry sorting and aeration device. It can facilitate multiple people to work simultaneously in centralized sorting operations, while avoiding the impact of sudden air pressure changes on shrimp and fish fry, improving the safety of the device, preventing water hammer effect from damaging the pipeline, extending the service life of the equipment, and is suitable for transportation and outdoor operations.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A multi-branch portable shrimp and fish fry dispensing and aeration device includes an oxygen cylinder and several flanges. A pressure control valve is installed at the air outlet of the oxygen cylinder via the flange. A multi-branch oxygen support is installed at one end of the pressure control valve via the flange. Each branch of the multi-branch oxygen support has a long flexible tube installed via the flange at its air inlet. An air gun is fixedly installed at the end of the long flexible tube furthest from the multi-branch oxygen support. A buffer air cylinder is installed at the end of the multi-branch oxygen support via the flange. A piston is slidably connected inside the buffer air cylinder, and a spring is installed between the piston and the inner wall of the buffer air cylinder.

[0011] Furthermore, an independent gas valve is fixedly installed on the top of the oxygen cylinder.

[0012] Furthermore, the number of branch air ports on the multi-branch oxygen support is no less than four.

[0013] Furthermore, the interior of the buffer cylinder consists of an air groove and a sliding groove, with the diameter of the air groove being smaller than the diameter of the sliding groove.

[0014] The piston slides inside the groove.

[0015] Furthermore, the two ends of the spring are fixed to the piston end face and the inner wall end of the buffer cylinder, respectively, and the spring is always kept in a compressed state.

[0016] Furthermore, on the multi-branch oxygen support, the distance between any two adjacent branch air ports is equal.

[0017] 3. Beneficial Effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] ① This solution, through the design of a multi-branch oxygen support, can support multiple people to work at the same time, significantly improving the dispensing efficiency. The equidistant layout of any adjacent branch air inlets ensures uniform airflow distribution and avoids local oxygen shortage. At the same time, it facilitates multiple people to work at the same time in centralized dispensing operations.

[0020] With dual regulation by pressure control valve and independent air valve, the oxygen output pressure can be precisely controlled to adapt to the needs of different dispensing scenarios, while avoiding the impact of sudden air pressure changes on shrimp fry and fish fry, thus improving the safety of the device.

[0021] ② In this solution, the buffer air cylinder absorbs pressure fluctuations when the air gun is suddenly shut off through the linkage of the piston and spring, effectively preventing water hammer effect from damaging the pipeline and extending the service life of the equipment;

[0022] All components in the device are connected via flanges, facilitating quick disassembly and maintenance. The lightweight design of the long hose and air gun makes it suitable for transportation and outdoor operations. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1 - Figure 4 A multi-branch portable shrimp and fish fry dispensing and oxygenation device includes an oxygen cylinder 1 and several flanges 2. The air outlet of the oxygen cylinder 1 is equipped with a pressure control valve 3 through the flange 2. One end of the pressure control valve 3 is equipped with a multi-branch oxygen support 4 through the flange 2. Each branch air outlet of the multi-branch oxygen support 4 is equipped with a long hose 5 through the flange 2. An air gun 6 is fixedly installed at the end of the long hose 5 away from the multi-branch oxygen support 4. A buffer air cylinder 7 is installed at the end of the multi-branch oxygen support 4 through the flange 2. A piston 8 is slidably connected inside the buffer air cylinder 7. A spring 9 is installed between the piston 8 and the inner wall end of the buffer air cylinder 7.

[0031] See Figure 1 Specifically, an independent air valve 101 is fixedly installed on the top of oxygen cylinder 1.

[0032] The oxygen cylinder 1 can be closed by using the independent valve 101, and the oxygen cylinder 1 can be easily replaced by the corresponding flange 2.

[0033] See Figure 1 , Figure 2 , Figure 3 Specifically, the number of branch air ports on the multi-branch oxygen stent 4 shall not be less than four.

[0034] The multi-branch oxygen support 4 has multiple branch air inlets, which facilitates the separate packaging and oxygenation of multiple groups of shrimp fry and fish fry.

[0035] See Figure 4 Specifically, the interior of the buffer air cylinder 7 consists of an air groove 701 and a sliding groove 702, with the diameter of the air groove 701 being smaller than the diameter of the sliding groove 702.

[0036] Piston 8 slides inside groove 702.

[0037] Specifically, the two ends of the spring 9 are fixed to the end face of the piston 8 and the end of the inner wall of the buffer cylinder 7, respectively, and the spring 9 is always kept in a compressed state.

[0038] The air groove 701 is connected to the air passage of the multi-branch oxygen support 4. The slide groove 702 restricts the movement direction and range of the piston 8. When multiple air guns 6 are closed at the same time, it can play a buffering role. At this time, the spring 9 is further compressed and the piston 8 slides to avoid water hammer effect causing damage to the multi-branch oxygen support 4.

[0039] See Figure 1 , Figure 2 , Figure 3 Specifically, on the multi-branch oxygen stent 4, the distance between any two adjacent branch air ports is equal.

[0040] Working principle:

[0041] After oxygen is output from oxygen cylinder 1, the pressure is regulated by pressure control valve 3, and the multi-branch oxygen support 4 splits the flow. The oxygen is then guided to the air gun 6 by the corresponding long hose 5 and sprayed out at the air gun 6. During this process, the independent air valve 101 can quickly cut off the gas source.

[0042] During normal oxygen supply: the airflow is stably output through the gas trough 701, and the piston 8 is in the initial position of the slide 702 under the tension of the spring 9. When the valve is suddenly closed: the gas pressure rises sharply, pushing the piston 8 to compress the spring 9, and the volume of the slide 702 increases to temporarily store the high-pressure gas. After the gas pressure is balanced, the spring 9 returns to its original position. This process allows excess oxygen to be released through the buffer system, avoiding back pressure impacting the oxygen cylinder 1.

[0043] During operation, each branch air gun 6 can be operated independently, and the pressure control valve 3 monitors the total air pressure in real time to ensure that the opening and closing of any branch does not affect the oxygen supply stability of other branches.

[0044] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
