Description

Technical Field

[0001] The utility model relates to the technical field of fresh fish transport vehicles, in particular to a water circulation device for fresh fish transport vehicles. Background Art

[0002] Fresh fish transport vehicles are used as a means of transport for long-distance transportation of fresh aquatic products. They have large transport capacity and low transport costs, so they are widely used. Fresh fish transport vehicles are equipped with refrigeration equipment and oxygen injection equipment, which can keep the water in the water tank at a low temperature and sufficient oxygen content, thereby improving the transportation survival rate of aquatic products.

[0003] At present, fresh fish transport vehicles are equipped with water circulation devices to cooperate with refrigeration equipment and oxygen injection equipment to accelerate the circulation of water in the water tank and ensure that the water temperature and oxygen content in various parts of the water tank are consistent. However, the water circulation devices of some existing fresh fish transport vehicles lack a separate filtering structure and are only filtered by the filtering structure of the water pump itself. The residue particles generated by the respiration and excretion of aquatic products during transportation are small and cannot be effectively filtered. Since the single transportation volume of aquatic products is large and the transportation time is long, the aquatic products generate more residues, which will affect the water quality and thus reduce the transportation survival rate of aquatic products. Therefore, a water circulation device for a fresh fish transport vehicle is proposed to address the above problems. Utility Model Content

[0028] Workflow: The water tank 1 of this device is an existing component. This device is installed on a live fish transport vehicle for use. The water pump 7 of this device is an electrical instrument. There is a mobile power source on the live fish transport vehicle, and the water pump 7 can be powered by the mobile power source. There is an external controller on the live fish transport vehicle, and the operation state of the water pump 7 can be controlled through the external controller. All of the above are existing technologies. Before use, fill the water tank 1 with clean water and add the aquatic products to be transported into the water tank 1. The driver turns on the water pump 7 through the external controller. The water pump 7 pumps water through the confluence pipe 6. The water at the bottom of the water tank 1 can be pumped out through the suction pipe 2 and the suction nozzle 3. The grid plate of the suction nozzle 3 can prevent smaller aquatic products from being sucked into the suction nozzle 3. The pumped water can return to the water tank 1 again from the drain pipe 4 and the drain nozzle 5 after passing through the water pump 7 and the filter box 8 on the top of the support plate 9, thus forming a water cycle. The grid plate of the drain nozzle 5 can prevent smaller aquatic products from accidentally entering the drain nozzle 5. During the water cycle process, water enters from the water inlet on the left side of the filter box 8. Since the sealing plate 12 seals the top of the collection shell 14, after the water is double-filtered by the first filter plate 15 and the second filter plate 16 inside the support frame 13, it can be discharged from the water outlet on the right side of the filter box 8. The first filter plate 15 and the second filter plate 16 can effectively filter the residue particles in the water. The particulate matter is intercepted and collected in the collection shell 14 inside the filter box 8. The particulate matter content in the transparent collection shell 14 can be observed through the viewing windows 10 on the front and back sides of the filter box 8. When there is more particulate matter in the collection shell 14, the water pump 7 can be paused. Since the filter box 8 is at a relatively high position, the water in the filter box 8 flows back to the water tank 1 through the drain pipe 4. At this time, open the sealing plate 11 and take out the support frame 13 and the collection shell 14, pour out the particulate matter in the collection shell 14, wash the support frame 13, the collection shell 14, the first filter plate 15 and the second filter plate 16 and then install them back into the filter box 8, and then the water pump 7 can be restarted. This process is simple, fast, time-saving and labor-saving. This device can effectively filter water during the water cycle process, intercept and collect the residue particles generated by the respiration and excretion of aquatic products during transportation, and the collection amount of the residue particles can be directly observed. When there is more particulate matter collected, the water cycle can be paused and the particulate matter can be quickly poured out, and then the water cycle can be restarted, so as to ensure the water quality during transportation, and further ensure that the survival rate of aquatic products during transportation will not be reduced due to water quality problems.
