Description

Technical Field

[0001] This utility model relates to the field of fish oil processing and filling technology, specifically to a storage, filling, and nitrogen-filling device for fish oil processing. Background Technology

[0002] Fish oil is rich in various unsaturated fatty acids, offering numerous health benefits such as lowering blood lipids, preventing cardiovascular disease, anti-inflammation, and promoting brain development. It has wide applications in the food, health product, and pharmaceutical industries. However, the unsaturated fatty acids in fish oil are chemically reactive and readily react with oxygen in the air to produce harmful substances such as peroxides, aldehydes, and ketones. This not only darkens the color and deteriorates the odor of the fish oil, reducing its nutritional value and sensory quality, but may also produce harmful components, affecting its safety and efficacy. Therefore, nitrogen purging is used during storage and bottling. However, existing nitrogen purging devices, after injecting a large amount of high-pressure nitrogen into the tank, move the tank to the capping station via a conveyor. During this movement, the open end of the tank is exposed for an extended period, causing the high-pressure nitrogen to escape and allow air to enter, resulting in poor purging effectiveness. Therefore, a new nitrogen purging device for fish oil processing, storage, and bottling is needed to solve these problems. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses a first electric push rod to drive a movable limiting frame and a quantitative addition unit to move synchronously forward along a track plate to the capping position of the tank. During this process, the quantitative addition unit remains at the tank opening, using a pressing plate and rubber gaskets to seal the opening, effectively preventing nitrogen gas from overflowing from the tank and avoiding external air from entering.

The quantitative addition unit is equipped with a turbine flow meter and a flow control valve. After the delivery pipe delivers nitrogen to the flow control valve, the nitrogen flow rate can be precisely controlled. After being metered by the turbine flow meter, the nitrogen is sprayed into the tank through the nozzle, accurately controlling the amount of nitrogen added to the tank to meet the nitrogen filling requirements of different sizes of fish oil tanks and ensuring the stability and consistency of the nitrogen filling process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides an embodiment of a nitrogen-filling and storage device for fish oil processing, comprising a first electric push rod 1, a track plate 2, a movable limiting frame 3, a fixed plate 4, a quantitative addition part 5, and a fixed frame 6. The fixed frame 6 is fixedly connected to one end of the track plate 2. The first electric push rod 1 is fixedly installed on the fixed frame 6. The bottom end of the movable limiting frame 3 is slidably engaged with the track plate 2, and the front end of the first electric push rod 1 is fixedly connected to the bottom end of the movable limiting frame 3. The fixed plate 4 is fixedly installed on the inner side of the track plate 2. The quantitative addition part 5 is disposed on the movable limiting frame 3. The first electric push rod 1 can drive the movable limiting frame 3 and the quantitative addition part 5 to move forward synchronously with the tank along the track plate 2 to the position where the cap is added. During this process, the quantitative addition part 5 is always located at the opening of the tank, sealing the opening so that the added nitrogen does not overflow and external air does not enter the interior of the tank. Then, the sealing cap is quickly screwed on. The device is fixedly installed in the designated position by the fixed plate 4.

[0018] The metering unit 5 includes a second electric push rod 7, a sliding adjustment frame 8, a fixed mounting plate 9, a third electric push rod 10, a turbine flow meter 11, a delivery pipe 12, a flow control valve 13, a pressing plate 14, and a nozzle 16. The sliding adjustment frame 8 is fixedly connected to the upper end of the second electric push rod 7, and the fixed mounting plate 9 is fixedly connected to the end of the sliding adjustment frame 8. The third electric push rod 10 is fixedly mounted on the fixed mounting plate 9 by bolts. The turbine flow meter 11 is fixedly connected to the front end of the third electric push rod 10. The pressing plate 14 is fixedly connected to the bottom end of the turbine flow meter 11. The flow control valve 13 is fixedly connected to the upper end of the turbine flow meter 11. The delivery pipe 12 is fixedly mounted on the flow control valve 13. The nozzle 16 is fixedly connected to the middle of the bottom end of the pressing plate 14. The nozzle 16 communicates with the interior of the turbine flow meter 11. The delivery pipe 12 is connected to an external nitrogen supply device through a hose.

[0019] A rubber gasket 15 is fixedly installed at the bottom of the pressing plate 14.

[0020] The sliding adjustment frame 8 is slidably engaged with the movable limit frame 3, and the second electric push rod 7 is fixedly installed on the movable limit frame 3.

[0021] The nozzle 16 is located on the side of the track plate 2 away from the fixed plate 4.

[0022] The sliding adjustment bracket 8 is arranged in a cross shape, which ensures stability during sliding.

[0023] Working principle: When adding nitrogen, the second electric push rod 7 drives the sliding adjustment frame 8 to slide on the moving limit frame 3. The fixed mounting plate 9 serves as the basic support component. The third electric push rod 10 pushes the turbine flow meter 11 forward, thereby adjusting the position of the nozzle 16 so that it is aligned with the opening of the fish oil tank. This also brings the pressing plate 14 close to the tank opening, and when the nozzle 16 is inserted into the opening, the pressing plate 14 seals the opening of the fish oil tank. The rubber gasket 15 fixedly installed at the bottom of the pressing plate 14 provides a sufficient seal to prevent nitrogen leakage and the entry of external air. The delivery pipe 12 delivers nitrogen to the flow control valve 13. After the flow control valve 13 accurately controls the nitrogen flow, the nitrogen is metered by the turbine flow meter 11 and then sprayed into the tank from the nozzle 16, realizing the filling and nitrogen filling operation of the fish oil. When an appropriate amount of nitrogen is filled into the tank, the first electric push rod 1 is activated. Because it is fixedly installed on the fixed frame 6 and its front end is aligned with the tank opening, the first electric push rod 1 is activated. The bottom end of the movable limiting frame 3 is fixedly connected and slidably engaged with the track plate 2. Therefore, the first electric push rod 1 can drive the movable limiting frame 3 and the quantitative addition part 5 to move forward synchronously with the tank along the track plate 2 to the position where the cap is added. During this movement, the quantitative addition part 5 is always located at the opening of the tank. The opening is sealed by the pressing plate 14 and the rubber gasket 15, so that the nitrogen added inside the tank will not overflow, and the outside air will not enter the inside of the tank. When the device moves to the capping position, the pressing plate 14 and the nozzle 16 quickly rise and are pulled out from the opening to reset. Then, the tank is quickly screwed to add the sealing cap, completing the sealing and preservation of the fish oil after filling and nitrogen filling, ensuring the quality and safety of the fish oil. The entire device achieves continuous, efficient and sealed operation of the fish oil filling and nitrogen filling process through the coordinated action of each component, effectively solving the problems existing in the prior art.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
