Description

Technical Field

[0001] This utility model relates to the field of temporary holding tank technology, and in particular to a temporary holding tank for crayfish production line. Background Technology

[0002] Temporary holding tanks for production lines are used to temporarily store aquatic products and fresh seafood awaiting processing or transfer within the production line. They are equipped with temperature control, oxygenation, and water circulation functions to maintain the freshness of the ingredients and prevent spoilage before processing. They are well-suited to the high-efficiency flow requirements of food processing production lines and are closely related to crayfish processing. Crayfish require a certain amount of time from being caught to being processed, and temporary holding tanks can ensure that they remain fresh within the production line, reducing losses.

[0003] In existing technologies, some crayfish production lines use temporary holding tanks that simulate a suitable natural aquatic environment for crayfish survival. These tanks also achieve automated cleaning and temporary holding management, providing healthy and fresh raw materials for subsequent processing. The tanks continuously inject filtered, temperature-controlled, and oxygenated water through an inlet system to maintain stable dissolved oxygen levels and water quality, preventing crayfish from being stressed due to lack of oxygen or sudden changes in water temperature. The sloping bottom design, combined with a bottom drain and a timed water circulation device, promptly removes crayfish excrement, uneaten feed, and other impurities, preventing water quality deterioration.

[0004] However, in actual use, if the conveying pipe is connected to the downstream cleaning, sorting or wastewater treatment process, the backflow will bring back pollutants such as sewage, detergent residue, crayfish excrement, and dead individual remains from the downstream into the temporary holding tank. These pollutants will quickly consume dissolved oxygen in the water, breed bacteria and harmful microorganisms, and cause the concentration of ammonia nitrogen and nitrite in the water to increase, triggering stress reactions in crayfish. In response to the above problems, a temporary holding tank for crayfish production lines is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a temporary holding tank for crayfish production lines, aiming to solve the problem that some temporary holding tanks used in existing crayfish production lines are difficult to prevent backflow in the conveying pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model constructs a water circulation filtration system by setting up a water storage tank, two pumps, a delivery pipe, and a filter assembly. One pump draws water from the temporary holding tank into the water storage tank, where it is purified by a filter plate and an activated carbon plate. The other pump returns the purified water to the temporary holding tank. The anti-backflow mechanism uses water pressure to push the sealing plate to overcome the spring force of the return spring to achieve water flow. When the pump stops working, the return spring automatically closes the sealing plate and the sealing ring, effectively preventing water backflow in the water storage tank. This design achieves continuous water purification, ensures the cleanliness of the temporary holding environment, and improves the operational stability and reliability of the water circulation system.

[0025] 2. In this utility model, a disassembly and assembly mechanism is provided on the placement net frame, enabling rapid assembly and disassembly of the net frame. During operation, the limit lever is pulled to unlock, and the sliding lever is pressed to retract under the action of the installation spring and detach from the holding tank body. The net frame can then be easily removed or placed using the handle. During installation, the spring's reset action automatically locks the sliding lever into the tank body, and the limit lever provides a secondary lock. This design simplifies the process of taking out and placing crayfish, and the double-locking structure ensures the stability of the placement net frame during the holding process, effectively preventing crayfish from escaping and improving the efficiency and safety of production operations.

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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a temporary holding tank for a crayfish production line, comprising a holding tank body 1. The holding tank body 1 provides a temporary holding space for crayfish, with a smooth inner wall to prevent crayfish from climbing, escaping, or suffering surface damage. A water storage tank 2 is fixedly connected to the rear exterior of the holding tank body 1. The water storage tank 2 stores fresh water to be replaced or recycled water, providing a stable water supply to the holding tank. A filter cover prevents impurities from entering. Pump bodies 3 are fixedly connected to the left and right exterior sides of the water storage tank 2. The pump bodies 3 provide power for water circulation, transporting water from the water storage tank 2 to the holding tank body 1. A filter screen prevents impurities from entering the pump body 3 and causing blockage. A rubber sealing ring ensures a tight seal, preventing leakage from affecting the operating efficiency of the pump body 3. The drive end of the pump body 3... A fixed connection to the conveying pipe 5 is provided, which is responsible for guiding the water conveyed by the pump body 3 into the temporary holding tank. The spray head disperses the water flow to avoid direct impact on the crayfish. An anti-backflow mechanism 4 is fixedly connected to the outside of the conveying pipe 5. A placement net frame 8 is slidably connected inside the temporary holding tank body 1. The placement net frame 8 is used to hold the crayfish in a centralized manner, which is convenient for batch handling and transfer. The mesh design ensures smooth water circulation and maintains a good temporary holding environment. Disassembly and assembly mechanisms 10 are fixedly connected to the left and right sides of the placement net frame 8. The disassembly and assembly mechanism 10 includes a connecting plate 101, which serves as the basic component of the disassembly and assembly mechanism 10 and provides installation support for the sliding clamp 102 and the limiting plate 103. The L-shaped structure saves space and facilitates the transmission of force.

[0034] Specifically, the main body of the temporary holding tank 1 protects crayfish from escaping and injury; the water storage tank 2 provides stable water supply and prevents impurities; the pump body 3 drives water circulation, prevents blockage and leakage; the delivery pipe 5 sprays water inlet to avoid impact; the net frame 8 facilitates the handling of crayfish and maintains water circulation; the disassembly and assembly mechanism 10 and the connecting plate 101 save space. Overall, it ensures a good temporary holding environment, is easy to operate, and improves the safety and efficiency of crayfish temporary holding.

[0035] The connecting plate 101 is externally fixedly connected to the left and right sides of the outer surface of the mesh frame 8. A sliding latch 102 is slidably connected to the outside of the connecting plate 101. The sliding latch 102 achieves locking or disengagement of the latch head with the limiting latch 105 through sliding. The T-shaped structure facilitates gripping and operation. A limiting plate 103 is slidably connected inside the connecting plate 101. The limiting plate 103 limits the maximum stroke of the sliding latch 102, preventing the latch head from overextending or falling off. Welding ensures synchronous movement with the sliding latch 102. A mounting spring 104 is sleeved on the outside of the sliding latch 102. Spring 104 provides continuous clamping force to sliding lever 102, ensuring that it remains locked when there is no external force. Limit lever 105 is slidably connected to the outside of the temporary holding tank body 1. Limit lever 105 cooperates with sliding lever 102 to adjust the height of the mesh frame 8. Multiple positioning holes allow the height of the mesh frame to be adjusted according to the temporary holding requirements. The outside of limit lever 105 is clamped to the outside of sliding lever 102. One end of spring 104 is fixedly connected to the outside of connecting plate 101, and the other end of spring 104 is fixedly connected to the outside of limit plate 103.

[0036] Specifically, the connecting plate 101 supports the sliding rod 102 and the limiting plate 103. The T-shaped structure of the sliding rod 102 facilitates operation. The limiting plate 103 prevents the rod from falling off and moves synchronously. The spring 104 ensures that the rod remains locked. The limiting rod 105 has multiple positioning holes to adjust the height of the mesh frame. Overall, the height of the mesh frame 8 is adjustable and the locking is stable. The operation is convenient and adaptable to different temporary maintenance needs.

[0037] The anti-backflow mechanism 4 includes a mounting housing 41, which serves as the basic frame for the anti-backflow mechanism and provides installation space for internal components. The mounting housing 41 is externally fixedly connected to the outside of the right-side delivery pipe 5. A cross-shaped placement plate 42 is fixedly connected to the inside right side of the mounting housing 41, providing stable support for the connecting housing 43. The cross structure minimizes obstruction to water flow while ensuring strength. The connecting housing 43 is externally fixedly connected to the cross-shaped placement plate 42, providing precise guidance for the sliding rod 44 and ensuring its smooth axial movement. The tapered guide structure facilitates the sliding rod's movement. When 44 is reset smoothly, a sliding rod 44 is slidably connected to the outside of the housing 43. The sliding rod 44 drives the sealing plate 461 to open and close by sliding axially. The chrome-plated surface reduces friction and wear, ensuring that the sliding accuracy is maintained after long-term use. A reset spring 45 is sleeved on the outside of the sliding rod 44. The reset spring 45 provides continuous sealing pressure to the sealing plate 461 to ensure reliable sealing when there is no positive water flow. A sealing assembly 46 is fixedly connected inside the housing 41. The sealing assembly 46 includes a sealing plate 461. The sealing plate 461 is the core component for achieving sealing and can tightly fit the sealing ring 462.

[0038] Specifically, in the anti-backflow mechanism 4, the mounting housing 41 is used for component installation, the cross-shaped placement plate 42 stably supports the connecting housing 43 and minimizes water flow obstruction, the connecting housing 43 guides the sliding rod 44 to move smoothly, the sliding rod 44 with sealing plate 461 opens and closes, and the return spring 45 ensures that the sealing plate 461 seals reliably, preventing backflow of water as a whole, ensuring stable water circulation, and improving the reliability of water supply to the temporary holding tank.

[0039] The sealing plate 461 is externally fixedly connected to the outside of the sliding rod 44. A sealing ring 462 is internally fixedly connected to the mounting housing 41. The sealing ring 462 provides a sealing reference surface for the sealing plate 461, and its mirror polishing ensures a tight fit with the sealing plate 461. The L-shaped cross-section enhances structural strength and prevents deformation under pressure. The outside of the sealing plate 461 contacts the outside of the sealing ring 462. A filter assembly 47 is slidably connected inside the water storage tank 2. The filter assembly 47 includes a top cover 471, which serves as both the mounting base for the filter assembly 47 and a seal for the top opening of the water storage tank 2. To prevent dust and impurities from falling in, the top cover 471 is slidably connected to the outside of the water storage tank 2. A filter plate 472 is fixedly connected to the bottom of the top cover 471. The filter plate 472 performs physical filtration of the water source. The multi-layer filter structure intercepts impurities of different sizes step by step, ensuring that the water entering the water storage tank 2 is free of particulate matter. Activated carbon plates 473 are fixedly connected to the left and right sides of the top cover 471. The activated carbon plates 473 use the adsorption effect of activated carbon to remove odors, pigments and some organic pollutants from the water, improving water quality. The honeycomb structure increases the contact area and improves adsorption efficiency.

[0040] Specifically, the sealing plate 461 and the sealing ring 462 fit tightly to prevent backflow, and the sealing ring 462 has a strong structure to prevent deformation; the top cover 471 in the filter assembly 47 prevents impurities from entering the water storage tank 2, the filter plate 472 filters impurities step by step, and the activated carbon plate 473 removes odors and improves water quality. The whole system ensures that there is no backflow in the water circuit and that the water is clean, providing a high-quality water environment for the temporary holding of crayfish.

[0041] Reference Figures 2 to 4 The sealing plate 461 is externally slidably connected to the inside of the mounting shell 41, and the sliding rod 44 is externally slidably connected to the inside of the mounting shell 41. Oxygenators 6 are fixedly connected to the left and right sides of the temporary holding tank body 1. Oxygenators 6 supplement the water in the temporary holding tank with oxygen, ensuring that the crayfish get sufficient oxygen during the temporary holding process and avoid death or decreased vitality due to lack of oxygen. The symmetrical installation on both sides makes the oxygen distribution more even. Oxygen pipes 7 are fixedly connected to the outside of the oxygenator 6. Oxygen pipes 7 are responsible for transporting the oxygen generated by the oxygenator 6 to the bottom of the temporary holding tank. They are suitable for long-term immersion in water. The reinforced structure prevents the pipe from being deformed and blocked by pressure. The outside of the oxygen pipe 7 is fixedly connected to the bottom of the inside of the temporary holding tank body 1. Handles 9 are fixedly connected to the front and rear sides of the net frame 8. The handles 9 provide convenient force points for picking up and putting down the net frame 8. The U-shaped design is easy to hold with both hands and is suitable for operators to carry the net frame containing crayfish.

[0042] Specifically, the sealing plate 461 and the sliding rod 44 slide smoothly within the mounting housing 41, helping to prevent backflow and sealing. The oxygenator 6 supplies oxygen from both sides to maintain the vitality of the crayfish. The oxygen pipe 7 is resistant to aging and delivers oxygen to the bottom of the pond. The handle 9 has a U-shaped design for easy gripping and placing / removing the net frame. The overall design strengthens the anti-backflow function, ensures uniform oxygen supply, improves operational convenience, and optimizes the temporary holding conditions for crayfish.

[0043] Working principle: When filtering and preventing backflow of the water inside the holding tank 1, the pump body 3 on the left side pumps the water inside the holding tank 1 into the water storage tank 2 through the delivery pipe 5. The water then passes through the filter plate 472 and activated carbon plate 473 to filter impurities. At this time, the pump body 3 on the right side drives the filtered water through the delivery pipe 5 to squeeze the sealing plate 461. This causes the sliding rod 44 outside the sealing plate 461 to slide inside the connecting housing 43, causing the return spring 45 outside the sliding rod 44 to deform. This allows the water to flow back into the holding tank 1 through the cross placement plate 42, thus achieving water circulation. When the pump body 3 stops, the return spring 45 rebounds, causing the sealing plate 461 to lock with the sealing ring 462, thus preventing backflow inside the water storage tank 2.

[0044] When removing the lobsters from the holding tank 1, pulling the limiting lever 105 separates it from the sliding lever 102, allowing the sliding lever 102 to slide inside the connecting plate 101. This causes the limiting plate 103 to slide inside the connecting plate 101, which in turn compresses the mounting spring 104, separating the sliding lever 102 from the outside of the holding tank 1. Then, pulling the handle 9 moves the net frame 8 to... The lobsters are removed from the holding tank body 1. When placing the lobsters inside the holding tank body 1, the handle 9 is used to move the placement net frame 8 into the holding tank body 1, so that the connecting plate 101 is in contact with the top of the holding tank body 1. At this time, by releasing the sliding latch 102, the mounting spring 104 rebounds, which in turn locks the sliding latch 102 against the outside of the holding tank body 1. Then, by inserting the limiting latch 105, the limiting latch 105 is locked against the outside of the sliding latch 102, thus realizing the placement of the lobsters.
