Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to an oxygen-filled transport packaging bag for living aquatic products. Background Art

[0002] During transportation, live aquatic products usually require special packaging methods to keep them fresh and alive. For aquatic products such as crabs or shrimps that are sensitive to temperature but can withstand low oxygen environments for a short period of time, you can use packaging boxes or small packaging boxes with ice cubes inside for short-distance transportation or short-term storage. Although this method is simple and low-cost, it is only suitable for short-distance and short-term transportation because it cannot provide enough oxygen and a suitable water quality environment for aquatic products. However, for live aquatic products such as fish that have higher requirements for dissolved oxygen and water quality in water, simply using packaging boxes or small packaging boxes with ice cubes is not applicable during long-distance transportation. This is because long-term transportation will gradually reduce the oxygen in the box, and the ice cubes cannot maintain stable water quality after melting, resulting in the death of fish due to lack of oxygen or deterioration of water quality. Therefore, when transporting high-demand aquatic products such as fish over long distances, special packaging bags for live aquatic products are required.

[0003] At present, during the transportation process, the existing packaging bags are closed, and the contact area between water and oxygen in the packaging bags is small, resulting in uneven distribution of oxygen in the water body. This makes aquatic products tend to gather in areas with more concentrated oxygen, accelerating the consumption of oxygen in this area, while oxygen in other areas is not fully utilized. As transportation proceeds, this uneven oxygen consumption causes the overall oxygen level to drop rapidly to a critical point, causing the risk of overall oxygen depletion. Therefore, the present application provides an oxygenated live aquatic product transportation packaging bag to meet the demand. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an oxygen-filled live aquatic product transport packaging bag to solve the existing problem of small contact area between water and oxygen in the packaging bag and uneven oxygen distribution during the transport of live aquatic products.

[0014] In the above scheme, a bubble plate and a contact plate are provided. The bubble plate is located at the bottom of the bag body and continuously releases tiny bubbles. The bubbles are in full contact with water during the rising process, thereby increasing the amount of dissolved oxygen. At the same time, the bubbles released by the bubble plate will encounter peaks and troughs during the rising process, which will break up large clusters of bubbles and disperse them into smaller bubbles, thereby increasing the contact area between oxygen and water and promoting uniform distribution of oxygen.

DETAILED DESCRIPTION

[0025] The following is a detailed description of a polymer material injection molding device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an embodiment of the utility model provides an oxygenated live aquatic product transport packaging bag, comprising: a bag body 1; a bubble plate 5, which is arranged on the bottom wall of the inner cavity of the bag body 1, and is used to release tiny bubbles; two contact plates 6, which are respectively arranged on the inner walls of the bag body 1, and the bottoms of the contact plates 6 are in contact with the bubble plates 5; a plurality of wave crests 61, which are arranged on the contact plates 6 and are distributed along the lateral direction of the contact plates 6; a plurality of wave troughs 62, which are arranged on the contact plates 6 and are distributed along the lateral direction of the contact plates 6; and the wave crests 61 and the wave troughs 62 alternately form continuous longitudinal waves to ensure that the water flow generates continuous vortices and turbulence inside the packaging bag.

[0027] The bubble plate 5 is provided to release oxygen bubbles continuously or on demand, thereby increasing the oxygen content in the water body. At the same time, the rise of the bubbles also drives the circulation of the water body, which is conducive to the uniform distribution of oxygen and reduces the stress response of aquatic products due to lack of oxygen. The wave crest 61 is provided, and the vortex and turbulence inside the water body are guided by the wave crest 61 to enhance the dissolution and diffusion of oxygen, thereby improving the utilization rate of oxygen. At the same time, it also promotes the dispersion of harmful substances inside the water body, reduces the accumulation of local pollutants, and is conducive to maintaining a healthier and more stable aquatic environment. The trough 62 is provided to cooperate with the wave crest 61 to form a more complex water flow pattern, thereby further optimizing the circulation inside the water body.

[0028] like Figure 5 As shown, it also includes: a plurality of pores 63, which are arranged on the wave crest 61, and the pores 63 are arranged in a spiral or grid shape. By setting the pores 63 as additional points for oxygen release, oxygen can directly enter the water body through these holes, thereby increasing the contact area and dissolution efficiency of oxygen. The pores 63 are arranged in a spiral shape, which can reduce the aggregation of bubbles and avoid the formation of large bubble clusters, thereby reducing the impact and pressure on aquatic products, maintaining the stability of hydrodynamics, and reducing the pressure on organisms; the pores 63 are arranged in a grid shape, which reduces the dead angle of oxygen transmission and is conducive to the generation of smaller and denser bubbles. These tiny bubbles rise slowly and can be in contact with the water body for a longer time, thereby increasing the solubility of oxygen.

[0029] like Figure 5As shown, it also includes: the crest 61 is dome-shaped or triangular, which is used to change the dynamics of the water flow; the trough 62 is circular, semicircular or V-shaped, which is used to change the dynamics of the water flow. By setting the crest 61 to be dome-shaped, the water pressure can be more evenly dispersed and the pressure concentration on the bottom and side walls of the packaging bag can be reduced; the crest 61 is triangular, and the sharp edge of the triangle can cause local water flow disturbance, which helps to increase the dissolution of oxygen and the exchange of substances in the water body, especially in the area near the pore 63; the trough 62 is circular, which can evenly distribute stress and avoid stress concentration at certain points, which helps to reduce the risk of damage to the packaging bag under dynamic load; the trough 62 is semicircular, and the semicircular shape increases the bending ability of the packaging bag, so that it can better deform without breaking when squeezed; the trough 62 is V-shaped, and the V-shape can effectively guide the water flow to the lowest point, which is convenient for discharging accumulated water or changing water quality.

[0030] like Figure 1 As shown, the bag also includes: a handle 2, which is arranged on the top of the bag body 1; an oxygen inlet pipe 3, which is connected to the bag body 1 and is used to fill the bag with oxygen. By providing the handle 2, a convenient gripping point is provided, which is convenient for carrying and moving the packaging bag; by providing the oxygen inlet pipe 3, an external oxygen input channel is provided, and oxygen can be continuously or on demand added to the interior of the packaging bag.

[0031] like Figure 2 and Figure 4 As shown, it also includes: a suspension part 4, which is arranged in the bag body 1, and the suspension part 4 includes: a suspension line 41, which is arranged in the bag body 1; and the suspension line 41 is U-shaped. By setting the suspension part 4, during transportation, the suspended matter 44 can move along the suspension line 41, and the bag body 1 is divided into multiple areas by the limiting block 42; for those aquatic products that tend to sink to the bottom, such as some fish, shellfish or shrimps and crabs, the suspension part 4 can effectively prevent them from sinking to the bottom of the bag body 1, avoiding the accumulation of sediments and waste, reducing the risk of bacterial growth, and at the same time reducing the deterioration of water quality caused by the accumulation of biological metabolic waste in the bottom water body.

[0032] like Figure 4 As shown, it also includes: a plurality of limiting blocks 42, which are arranged on the suspension line 41; and a suspended object 44, which is movably arranged on the suspension line 41. By setting the limiting blocks 42 and limiting the movement range of the suspension line 41, the suspended object 44 is kept in an appropriate position in the water body, so as to avoid excessive concentration or collision of the aquatic product against the container wall during transportation, thereby reducing physical damage; by setting the suspension line 41, a movement track can be provided for the suspended object 44; by setting the suspended object 44, a platform or structure is provided, so that the aquatic product can remain suspended in the bag body 1 to avoid sinking to the bottom or accumulation.

[0033] like Figure 4As shown, it also includes: two plugs 43, which are detachably arranged on the suspended matter 44; the plugs 43 are made of an adsorbent material and are used to adsorb harmful substances in the water. A slot is set on the suspended matter 44, and the plugs 43 are inserted into the slots. If the plugs 43 need to be replaced, the plugs 43 are taken out; the plugs 43 purify the water quality and reduce harmful substances in the water that may threaten the health of aquatic products.

[0034] The technical solution provided by the utility model is as follows: unfold the top of the bag body 1, add a proper amount of water, pour the aquatic product in, seal the top of the bag body 1, and then connect it to the oxygen inlet pipe 3 through an external oxygen supply device to fill the bag body 1 with oxygen; carry the packaging bag to the transportation vehicle through the handle 2, and during the transportation, the bubble plate 5 continuously releases bubbles, and the bubbles will rise through the water body; provide a platform for the aquatic product through the suspended matter 44; when the water body circulates in the bag body 1, the alternating arrangement of the crests 61 and the troughs 62 will guide the water flow to form vortices and turbulence, and the vortex will help to disperse the bubbles to every corner of the water body, while the turbulence can accelerate the bursting of the bubbles; the bubbles released by the bubble plate 5 will encounter the crests 61 and the troughs 62 during the rising process, which will break up the large bubbles and disperse them into smaller bubbles, thereby increasing the contact area between oxygen and water and promoting the uniform distribution of oxygen.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
