Description

Technical Field

[0001] This application relates to the field of abalone processing technology, and in particular to an abalone processing brine soaking pretreatment device and processing method. Background Technology

[0002] As an important economic shellfish, the pre-processing of abalone before deep processing is crucial to ensuring the quality of the final product. Existing abalone pre-processing technologies typically include temporary holding, cleaning, and soaking to remove sand. This primarily relies on static soaking in holding tanks, supplemented by manual scrubbing to remove surface mucus and sand. In terms of operation, after initial cleaning, the abalone are placed in a brine tank for a certain period. During this time, water temperature and salinity are monitored periodically by manual inspection or simple equipment. The wastewater after soaking is usually discharged directly or partially reused after simple filtration. The entire production process involves multiple independent work units, and material transfer between stages largely depends on manual operation. Maintaining brine concentration and temperature control are also mainly achieved through manual addition of salt and natural regulation.

[0003] However, in existing technologies, due to the lack of integrated automatic processing mechanisms and efficient closed-loop circulation systems, it is difficult to achieve water conservation and precise and stable control of process parameters while ensuring the survival rate of abalone and the sand removal effect. This results in low pretreatment efficiency and fluctuations in treatment quality. Summary of the Invention

[0014] A method for brine soaking pretreatment of abalone for processing includes the following steps: S1. Brine preparation: Fresh water and salt are mixed using a brine preparation unit and then transported to a brine storage tank. The concentration of the prepared brine is 2.5% to 3%. S2. Constant temperature temporary holding: Place the abalone in room temperature water and hold for 10-15 minutes to restore their freshness and reduce stress damage; S3.

Water treatment: The water used to soak the abalone is in a flowing state. When it passes through the sedimentation tank, the mud and sand expelled by the abalone are removed. After the mud and sand are removed, it is transported to the mucus treatment tank to remove the mucus. Finally, it is transported to the brine storage tank to achieve water circulation. S6. Brine replenishment: After the brine storage tank level drops, the brine mixing component delivers the prepared brine to the brine storage tank to replenish the brine and adjust the brine concentration, enabling continuous operation.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides an apparatus and method for brine soaking pretreatment of abalone. This method integrates a spray assembly, an abalone soaking tank, a sedimentation tank, a mucus treatment tank, and a brine preparation assembly, using a brine storage tank as the core hub, thus constructing a complete automated processing flow. The spray assembly dynamically sprays and washes the abalone, while the brine cooling assembly maintains a low-temperature environment. This allows the mud and mucus adhering to the abalone's surface to be initially removed before entering the tank. Simultaneously, the low temperature effectively inhibits bacterial growth and reduces the stress response of the abalone. 2. Based on the cooperation of the conveyor belt and the turning component in the abalone soaking tank, the abalone is periodically turned over during the movement, which ensures that the soaking solution can come into full contact with the abalone body surface and promotes the full discharge of mud and sand in the body; with the help of the trapezoidal structure and gravity sedimentation principle of the sedimentation treatment tank, large particles of mud and sand in the wastewater can be quickly separated. Then, the supernatant is transported to the mucus treatment tank through the water pumping component, and the composite filter structure is used to intercept small organic debris and mucus, realizing efficient solid-liquid and liquid-liquid separation. 3. Based on this, the purified brine flows back to the brine storage tank through a U-shaped tube to form a closed loop. In conjunction with the brine mixing component, based on the feedback signal from the concentration detector, the Bernoulli tee structure is used to precisely control the mixing ratio of the gas-salt-water three phases, compensate the brine concentration in real time, and prevent blockage.

[0016] 4. This effectively solves the problems of discrete steps, serious water waste, and unstable quality caused by fluctuations in processing parameters in traditional processes. Therefore, it avoids frequent manual intervention, large wastewater discharge, and high abalone mortality rates, and significantly improves the continuity of pretreatment operations, resource utilization, and consistency of product quality.

[0017] In summary, this application achieves integrated control of the entire process from flushing, soaking, sand removal to wastewater purification and regeneration through the synergistic effect and logical closed loop of various functional modules. This not only significantly reduces energy and water consumption, but also ensures the stability of the treatment effect through precise parameter control, thus possessing extremely high industrial application value.

[0020] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will be described in further detail.

[0021] Reference Figure 1A pretreatment device for brine soaking in abalone processing includes a brine storage tank 1, a spray assembly 2 installed on the brine storage tank 1 for dynamically spraying and rinsing the abalone and assisting in removing impurities and mucus; an abalone soaking tank 3 installed on the brine storage tank 1 for low-temperature soaking of the abalone, an abalone conveyor belt 4 installed inside the abalone soaking tank 3, and a sedimentation treatment tank 5 located below the abalone soaking tank 3 for receiving soaking wastewater and achieving sedimentation separation of large particles of silt and sand. The brine storage tank 1 is located away from the sedimentation tank 5, and a sludge treatment tank 6 is installed on the side of the tank. The sludge treatment tank 6 is connected to the sedimentation tank 5 through a pumping assembly 7. The pumping assembly 7 is used to transport the water from which the sediment has been removed to the sludge treatment tank 6 to remove the sludge. After the sludge is treated, the sludge treatment tank 6 transports the clean brine back to the brine storage tank 1 to achieve closed-loop reflux and reuse of the purified brine. A brine mixing assembly 8 is installed at one end of the brine storage tank 1. The brine mixing assembly 8 is used to monitor and automatically compensate the brine concentration in real time to stabilize the pretreatment process parameters.

[0022] The brine storage tank 1 can refer to a container structure that serves as the central hub for the brine supply of the entire system, used to store the prepared pre-treated brine. In the overall technical solution, the brine storage tank 1 is connected to the spray assembly 2, the abalone soaking tank 3, the mucus treatment tank 6, and the brine mixing assembly 8, respectively, playing the role of collecting, buffering, and distributing brine to ensure that each processing unit has a stable brine source.

[0023] The spray assembly 2 refers to a fluid jetting mechanism installed on and connected to the brine storage tank 1, used to dynamically rinse the abalone entering the system. The function of the spray assembly 2 is to initially remove mud, sand, and some mucus adhering to the abalone's surface using the impact force of flowing brine, while simultaneously reducing stress on the abalone through the low-temperature brine. The spray assembly 2 works in conjunction with the abalone soaking tank 3, located in the path of the abalone before it enters the soaking tank 3. It forms a water curtain or spray zone through high-pressure or atmospheric-pressure jetting, allowing the abalone to undergo preliminary cleaning before entering the still water environment. The spray assembly 2 can be implemented by combining spray pipes, a spray pump, and spray heads.

[0024] Water is continuously sprayed into the abalone soaking tank 3 by the spray component 2. The impact force of the water generates bubbles, which increases the oxygen content in the abalone soaking tank 3 and can effectively improve the survival rate of abalone. The abalone soaking tank 3 refers to a tank structure located above or to the side of the brine storage tank 1, used to accommodate abalone for low-temperature soaking and sand removal treatment. The internal space of the abalone soaking tank 3 is sufficient to accommodate the movement of the abalone conveyor belt 4 and ensure that the abalone are completely submerged in the brine. The abalone soaking tank 3 is connected to the brine storage tank 1 to maintain liquid level balance or facilitate water exchange. In the overall system, the abalone soaking tank 3 is the core reaction site, and its internal environment (such as temperature and flow rate) directly affects the sand removal efficiency and survival rate of the abalone.

[0025] The abalone conveyor belt 4 refers to a conveying mechanism installed inside the abalone soaking tank 3, used to carry abalone and move them at a uniform speed within the tank 3. The function of the abalone conveyor belt 4 is to transport the abalone from the inlet to the outlet, while keeping them in a soaking state during the movement. The abalone conveyor belt 4 works in conjunction with the abalone turning component 9 to ensure that the abalone are evenly stressed during transport, preventing abalone accumulation. Simultaneously, it turns the abalone during soaking, effectively improving the abalone's ability to expel sand and sediment from its body.

[0026] The sedimentation treatment tank 5 can refer to the tank structure located below the abalone soaking tank 3, which is used to receive wastewater containing mud and sand impurities discharged from the abalone soaking tank 3.

[0027] The working principle of the sedimentation treatment tank 5 is to use gravity sedimentation to allow the denser mud and sand particles to sink naturally in the tank, thereby achieving preliminary solid-liquid separation.

[0028] The sedimentation tank 5 and the abalone soaking tank 3 are arranged vertically to facilitate gravity flow of wastewater. The bottom of the sedimentation tank 5 can be designed as an inclined or conical structure to facilitate the accumulation of impurities.

[0029] The slime treatment tank 6 refers to a purification unit located on the side of the brine storage tank 1 away from the sedimentation tank 5. It is used for deep filtration of the supernatant after sedimentation, removing abalone slime and small organic debris. The slime treatment tank 6 is connected to the sedimentation tank 5 via a pumping assembly 7, receiving relatively clear water from the sedimentation tank 5. The slime treatment tank 6 may contain filter cartridges, membranes, or other adsorbent materials. Its function is to be a key purification link in the closed-loop brine circulation, preventing slime backflow from contaminating the abalone or clogging the pipes. The slime treatment tank 6 can be a closed-pipe type or an open tank type, depending on the actual filtration requirements.

[0030] The pumping assembly 7 can refer to a power transmission device connecting the sedimentation tank 5 and the sludge treatment tank 6, such as a water pump, submersible pump, or pneumatic diaphragm pump. The function of the pumping assembly 7 is to provide power to extract the supernatant from the sedimentation tank 5 after gravity settling and transport it to the sludge treatment tank 6 for further treatment. The flow rate and head of the pumping assembly 7 can be matched and set according to the height difference between the two tanks and the pipeline resistance to ensure continuous and stable water flow.

[0031] The brine mixing component 8 refers to an automatic proportioning and control device installed at one end of the brine storage tank 1, used to monitor the brine concentration in real time and automatically replenish fresh water or salt. The function of the brine mixing component 8 is to maintain the stability of the brine concentration within the system, solving the problem of concentration fluctuations caused by water evaporation, water loss from abalone, or waste discharge. The brine mixing component 8 can be electrically connected to a concentration detection sensor to form a feedback control loop, automatically adding salt when the detected concentration is below the set value and automatically replenishing water when it is above the set value.

[0032] The core innovation of this application lies in constructing a closed-loop circulating treatment system that integrates dynamic rinsing, low-temperature soaking, tiered sedimentation, deep filtration of mucus, and automatic brine preparation. By spatially and functionally integrating the spray assembly 2, abalone soaking tank 3, sedimentation treatment tank 5, mucus treatment tank 6, and brine preparation assembly 8, the entire abalone pretreatment process is automated and continuous.

[0033] The working process and principle of this application are as follows: Abalone is first dynamically rinsed by low-temperature brine in the spray assembly 2 to remove most of the mud and mucus from its surface; then it enters the abalone soaking tank 3 and moves with the abalone conveyor belt 4 to be soaked in low-temperature water, which promotes the abalone to expel sand; the wastewater generated during soaking flows into the sedimentation treatment tank 5 below, where the mud and sand settle by gravity; the clear liquid at the top is pumped into the mucus treatment tank 6 by the water pumping assembly 7 to remove fine mucus and organic matter; the purified brine is returned to the brine storage tank 1 for reuse; during this process, the brine mixing assembly 8 monitors and adjusts the brine concentration in real time to ensure the stability of the process parameters of the entire circulation system.

[0034] Before the water in the sedimentation tank 5 is transferred to the slime treatment tank 6, the water valve on the pipe connecting the sedimentation tank 5 and the abalone soaking tank 3 needs to be closed. Water is then pumped out using the pumping assembly 7 to create negative pressure inside the sedimentation tank 5, allowing the gas in the sediment to be quickly discharged and the sediment to sink to the bottom of the sedimentation tank 5. The pumping assembly 7 then transfers the supernatant to the slime treatment tank 6 for further processing.

[0035] As a preferred embodiment, the solution of this application is specifically implemented as follows: After the device is started, the brine preparation component 8 injects fresh water and adds salt into the brine storage tank 1 to prepare a brine concentration of 2.5%~3%. The spray component 2 is turned on to cool the brine to 0~4℃, dynamically rinsing the abalone for about 30 seconds. The rinsed abalone falls onto the abalone conveyor belt 4 of the abalone soaking tank 3. The conveyor belt runs at a certain speed, and the abalone soaks in the tank for about 20 minutes. During this time, wastewater containing mud and sand continuously overflows to the sedimentation treatment tank 5 below. After settling for 10 minutes, the supernatant is pumped by the water pumping component 7 to the mucus treatment tank 6. After the mucus is filtered out, the clean brine returns to the brine storage tank 1 through the return pipe. During system operation, if the brine concentration detector detects a drop in concentration to 2.4%, the brine preparation component 8 automatically starts the salting program until the concentration returns to 2.8%.

[0036] Through the above technical solutions, this application achieves the following beneficial effects: Due to the combined dynamic rinsing and static soaking mechanism of the spray component 2 and the abalone soaking tank 3, the removal efficiency of impurities on the abalone surface is significantly improved; Because a tiered wastewater treatment system consisting of a sedimentation treatment tank 5 and a mucus treatment tank 6 is set up, and the purified water is returned to the brine storage tank 1, a closed-loop recycling of brine is achieved, greatly reducing water consumption and wastewater discharge; Because a brine mixing component 8 is equipped for real-time monitoring and automatic compensation, concentration fluctuations caused by manual control are effectively avoided, ensuring the stability of the abalone's sand-expelling rate and reducing stress-induced mortality.

[0037] Reference Figure 1 A brine concentration meter 12 is installed inside the brine storage tank 1, and the brine concentration meter 12 is electrically connected to the brine preparation assembly 8.

[0038] During the ongoing abalone pretreatment process, the salinity concentration in the brine storage tank 1 fluctuates as the abalone expels sand, sheds mucus, and loses moisture through evaporation or carry-over. A brine concentration detector 12, installed inside the tank, continuously collects the current salinity signal and transmits this analog or digital signal to the brine mixing component 8. Upon receiving the signal, the brine mixing component 8 compares it with the target concentration value stored internally. If the current concentration is determined to be too low, the salt-adding mechanism automatically performs a quantitative salt dispensing operation; if the concentration is normal, no action is taken. The entire process requires no manual intervention, achieving automated linkage from sensing to execution, ensuring the stability of the soaking environment.

[0039] Reference Figure 1 , Figure 2The spray assembly 2 includes a spray pipe 21, a spray water pump 22 is installed on the spray pipe 21, a spray plate cavity 23 is fixed at the end of the spray pipe 21 away from the brine storage tank 1, a plurality of spray nozzles 24 are fixed in an array on the lower side of the spray plate cavity 23, and a brine cooling assembly 25 is installed on the spray pipe 21, which is connected to the brine preparation assembly 8.

[0040] The spray pump 22 is installed on the spray pipe 21. Its function is to provide pressure energy for the flow of brine in the pipeline, ensuring that the brine can reach the spray plate cavity 23 with sufficient flow rate and pressure and be sprayed out from the spray nozzle 24 to form a water column with scouring force to peel off the mud and some mucus from the abalone's body surface.

[0041] In this embodiment, the working process of the spray assembly 2 is as follows: When the system starts the pretreatment process, the spray water pump 22 starts working, drawing brine from the brine storage tank 1 and transporting it through the spray pipe 21; during the transport process, the brine cooling assembly 25 (the brine cooling assembly 25 can refer to a refrigeration device integrated on the spray pipe 21 for reducing the temperature of the brine, such as a compressor refrigeration module, a semiconductor refrigeration chip, or a plate heat exchanger, etc., with a thermometer installed inside) monitors and adjusts the temperature of the spray assembly 2, and the brine flowing through the brine cooling assembly 25 is cooled to the set temperature; subsequently, the low-temperature brine enters the spray plate cavity 23 and flows evenly inside it, and is sprayed downward through multiple spray nozzles 24 distributed in an array, performing all-round, dynamic low-temperature spray rinsing on the abalone located below; during this process, the brine concentration detector 12 monitors the brine concentration parameter in real time and adjusts the brine concentration through the brine mixing assembly 8 to ensure that the temperature of the spray brine is always maintained within a suitable range, completing the pre-cleaning and cooling treatment of the abalone.

[0042] As a preferred embodiment, the solution of this application is implemented as follows: Before the abalone enters the abalone soaking tank 3, it first passes through the treatment area of ​​the spray assembly 2. The spray water pump 22 operates at rated power, drawing brine from the brine storage tank 1 into the spray pipe 21. The brine is cooled as it flows through the brine cooling assembly 25 installed on the pipeline. The cooled brine flows into the spray plate cavity 23 spanning above the conveyor belt, and is sprayed downwards through dozens of evenly distributed spray nozzles 24 on the plate, producing a fine and pressurized jet of low-temperature brine. These jets cover the entire width of the abalone conveyor belt, powerfully washing the surface of the moving abalone and carrying away the attached mud and loose mucus. If an upward trend in water temperature is detected, the driving current of the brine cooling assembly 25 is immediately increased to enhance the cooling effect and ensure a constant spray water temperature. This effectively reduces the abalone's body temperature while ensuring the cleaning effect, preventing stress-induced death or rapid microbial growth due to excessively high water temperature.

[0043] Reference Figure 1 , Figure 3A drainage pipe 13 is provided between the sedimentation treatment tank 5 and the brine storage tank 1. A sealing switch 131 is installed on the drainage pipe 13. The bottom of the brine storage tank 1 is inclined. A sedimentation collection tank 14 is provided on the side of the brine storage tank 1 near the drainage pipe 13. A negative pressure connecting pipe 51 is installed on the sedimentation treatment tank 5. The negative pressure connecting pipe 51 is connected to a negative pressure pump. A sedimentation collection area 52 is provided at the lower end of the sedimentation treatment tank 5. A sewage pipe 53 is provided at the lower end of the sedimentation collection area 52. A sewage discharge switch 54 is installed on the sewage pipe 53. The sedimentation collection area 52 is trapezoidal.

[0044] After the soaking wastewater containing silt and sand impurities flows from the abalone soaking tank into the sedimentation treatment tank 5, the flow rate decreases, and large particles of silt and sand sink under gravity and fall into the trapezoidal sedimentation and accumulation zone 52 for centralized storage. The clarified liquid on the upper layer flows to the brine storage tank 1 through the drainage pipe 13. During this process, if a small amount of impurities also settle at the bottom of the brine storage tank 1, they will slide into the sedimentation and accumulation tank 14 along the inclined structure. When it is necessary to clean the silt and sand in the sedimentation treatment tank 5, the negative pressure pump connected to the negative pressure connection pipe 51 is started to generate negative pressure in the tank. At the same time, the drain switch 54 is opened. The negative pressure suction and gravity work together to quickly extract the silt and sand in the trapezoidal accumulation zone 52 through the drain pipe 53. If it is necessary to drain or maintain the brine storage tank 1, the sealing switch 131 can be closed to cut off the connection, or the impurities in the accumulation tank 14 can be discharged by controlling the sealing switch 131 in conjunction with the inclined bottom.

[0045] The bottom of the brine storage tank 1 is inclined, meaning that the bottom wall of the brine storage tank 1 is not horizontal, but has a certain angle relative to the horizontal surface. The function of this inclined structure is to use gravity to guide the trace impurities or silt deposited at the bottom of the tank to slide and collect at a lower position. The inclination angle can be set according to the actual situation. The sedimentation and collection tank 14 is located on the side of the brine storage tank 1 near the drain pipe 13 and at the lowest position of the inclined bottom. It can be a groove structure extending along the width of the tank or a pit-like structure with local depth. It is used to collect impurities that slide down from the inclined bottom surface and prevent impurities from spreading over a large area at the bottom of the tank and being difficult to clean. The sedimentation and collection tank 14 corresponds to the inlet position of the drain pipe 13, making it easier for the accumulated impurities to be discharged through the drain pipe 13 with the water flow or to be easily extracted. The negative pressure connecting pipe 51 installed on the sedimentation treatment tank 5 can refer to a pipeline assembly that connects one end to the internal space of the sedimentation treatment tank 5 and the other end to an external negative pressure pump (such as a vacuum pump or negative pressure fan). The function of the negative pressure connecting pipe 51 is to create a micro-negative pressure environment in the sedimentation treatment tank 5 through the suction force generated by the negative pressure pump. On the one hand, it can accelerate the settling speed of suspended particles in wastewater. On the other hand, it can assist in sucking out the viscous sludge deposited at the bottom during the sewage discharge stage, preventing the sewage discharge pipe 53 from being blocked. The installation position of the negative pressure connecting pipe 51 can be located in the upper gas phase space of the sedimentation treatment tank 5, or it can extend below the liquid surface but avoid the sedimentation accumulation area 52. The specific position can be set according to the flow field distribution requirements.

[0046] The sedimentation aggregation zone 52 at the lower end of the sedimentation treatment tank 5 can be a region formed by a downward indentation at the bottom of the tank to accommodate settled solids, and its shape is limited to a trapezoidal structure. This trapezoidal structure can refer to the longitudinal section of the sedimentation aggregation zone 52 being trapezoidal, that is, a bucket-shaped structure with a wide upper opening and a narrow lower opening. This structural design is conducive to the natural convergence of silt and sand towards the bottom center under the action of gravity, reducing dead corners and improving sludge discharge efficiency. The sewage pipe 53 connected to the lower end of the sedimentation aggregation zone 52 can be a straight pipe or a bend, used to discharge the concentrated silt and sand out of the tank. The sewage switch 54 installed on the sewage pipe 53 can be a sewage valve, used to control the start and stop of the sludge discharge operation. When the sediment accumulates to a certain amount, opening the sewage switch 54 can use the liquid level difference or negative pressure to assist in the discharge of sludge.

[0047] Reference Figure 1 The abalone conveyor belt 4 includes a soaking section 41, a lifting section 42 and a feeding section 43. An abalone turning component 9 is installed on the upper end of the abalone soaking tank 3. The abalone turning component 9 is located in the middle of the soaking section 41. The soaking section 41 refers to the section of the abalone conveyor belt 4 that is completely submerged below the brine surface and is used to continuously soak abalone at low temperatures to remove sand. This soaking section 41 occupies a major portion of the overall conveying path, and its function is to provide a stable still or slightly flowing water environment for the abalone, allowing them to fully open their shells and expel sand under reduced stress. The soaking section 41 connects end-to-end with the lifting section 42 and the dispensing section 43, forming a continuous material transport channel that ensures that the abalone's journey from entry to exit requires no manual intervention.

[0048] The lifting section 42 refers to the conveyor section with an upward inclination angle that connects the end of the soaking section 41 and the beginning of the delivery section 43. The main function of this lifting section 42 is to smoothly lift the abalone that has completed the soaking and sand-removal process from below the brine surface to the upper space for subsequent draining or transfer. The inclination angle of the lifting section 42 can be adjusted according to the friction coefficient of the conveyor belt and the abalone's anti-slip requirements.

[0049] The feeding section 43 can refer to the horizontal or slightly inclined section located at the end of the abalone conveyor belt 4, used to export the processed abalone from the abalone soaking tank 3. This feeding section 43 typically extends to the outside of the tank or connects to the receiving container of the next process, and its function is to realize the automatic feeding of abalone.

[0050] The abalone turning component 9 is a mechanical device installed on the upper part of the abalone soaking tank 3, with its working end extending into the space above the soaking section 41, used to turn the abalone over while it is moving. The name "Abalone Turning Component 9" derives from its core function: changing the posture of the abalone on the conveyor belt. The abalone turning component 9 is specifically positioned in the middle of the soaking section 41, meaning that when the abalone travels with the conveyor belt to the midpoint of the soaking journey, it will be actively intervened by this component and turned over. This positioning allows the abalone to contact the bottom or face the water flow with different sides of its body in the first and second halves of the soaking process, effectively solving the problem of dead zones in sand removal caused by prolonged adhesion to the conveyor belt on one side. There is a strict spatiotemporal coordination between the abalone turning component 9 and the abalone conveyor belt 4: the speed of the conveyor belt determines when the abalone passes the turning component 9, and the operating frequency or structural layout of the turning component 9 must match the speed of the conveyor belt to ensure that every passing abalone is turned over. This achieves dynamic posture adjustment of individual abalone without stopping the conveyor, ultimately resulting in uniform sand removal.

[0051] Specifically, this application constructs a continuous low-temperature soaking and sand-removal mechanism by coordinating a segmented abalone conveyor belt 4 with a centrally located abalone turning component 9. After entering the soaking section 41 via the feeding end, the abalone undergoes the first stage of sand removal under the influence of gravity and water flow. When it reaches the middle of the soaking section 41, the abalone turning component 9 above applies a force to change its original posture. The abalone then continues soaking and sand removal in its new posture for the remainder of the journey, finally being lifted above the liquid surface via the lifting section 42 and discharged by the feeding section 43. The entire process utilizes the segmented function of the abalone conveyor belt 4 to achieve natural division of the work area and overcomes the limitations of static soaking by using the centrally located turning component, ensuring thorough removal of sediment.

[0052] Reference Figure 1 , Figure 4 The abalone turning assembly 9 includes a turning platform 31 fixed on the abalone soaking tank 3, a head shaft 32 mounted on the turning platform 31, a pair of drive rollers 33 fixed on the shaft 32, the drive rollers 33 being in contact with the abalone conveyor belt 4, and a plurality of turning brushes 34 fixed on the shaft 32 for turning the abalone over; a rubber strip 35 in contact with the drive rollers 33 is mounted on the abalone conveyor belt 4; the drive rollers 33 are made of rubber; and the surfaces of the rubber strips 35 and the drive rollers 33 are provided with striped protrusions.

[0053] The tilting table 31 refers to the base structure used to support and fix the rotating shaft 32 and the drive roller 33. It is usually fixedly installed on the inner wall or top crossbeam of the abalone soaking tank 3, corresponding to the middle area of ​​the soaking section 41 of the abalone conveyor belt 4. The main function of the tilting table 31 is to provide a stable mounting base for the tilting mechanism, ensuring that the rotating shaft 32 remains horizontal and fixed in position during rotation, thereby ensuring that the tilting brush 34 can accurately act on the abalone on the conveyor belt.

[0054] The drive roller 33 refers to a wheel-shaped component that is fixedly sleeved on the rotating shaft 32 and in direct contact with the surface of the abalone conveyor belt 4. The drive roller 33 is preferably made of rubber. The function of the drive roller 33 is to act as an active friction component. Utilizing the friction between itself and the rubber strips 35 on the abalone conveyor belt 4, it is driven to rotate by the abalone conveyor belt 4, thereby driving the rotating shaft 32 to rotate. Using rubber to make the drive roller 33 increases the coefficient of friction of the contact surface, preventing slippage in wet or viscous conditions. Simultaneously, the rubber material has a certain elastic cushioning effect, reducing rigid impacts during mechanical transmission. The number of drive rollers 33 can be one or more pairs, symmetrically distributed on both sides of the rotating shaft 32 to balance the force.

[0055] The flipping brush 34 refers to a brush-like structure distributed axially and extending radially along the rotating shaft 32. It is used to gently turn and flip the abalone on the abalone conveyor belt 4 as the rotating shaft 32 rotates. The function of the flipping brush 34 is to gently turn the abalone, ensuring that all surfaces of the abalone are fully in contact with the brine during the soaking and sand-removal process, thus improving sand-removal efficiency and cleanliness. The flipping brush 34 can be made of soft nylon, silicone, or other food-grade flexible materials to avoid damage to the abalone's surface from hard bristles.

[0056] The rubber strip 35 can refer to a long, raised structure laid or molded onto the surface of the conveyor belt 4 along its running direction, and its material is also rubber. The function of the rubber strip 35 is to form a friction pair with the drive roller 33, generating sufficient driving torque through the tight contact between their surfaces. The arrangement of the rubber strip 35 on the conveyor belt 4 must precisely correspond to the position of the drive roller 33 to ensure the continuity of the transmission link. The cross-sectional shape of the rubber strip 35 can be semi-circular, trapezoidal, or rectangular, and its width and height can be designed to match the dimensions of the drive roller 33.

[0057] The raised stripes refer to the textured structure created on the outer circumferential surface of the drive roller 33 and the surface of the rubber strip 35. The function of the raised stripes is to increase the roughness and engagement capability of the contact interface, further preventing slippage caused by brine lubrication or viscous adhesion, and ensuring that the drive roller 33 can accurately follow the speed of the abalone conveyor belt 4 for synchronous rotation. The shape of the raised stripes can be transverse lines, longitudinal grooves, or grid-like protrusions. Specifically, the working process and principle of this application are as follows: When the abalone conveyor belt 4 moves the abalone in the soaking section 41, the rubber strips 35 on the surface of the conveyor belt move accordingly. Since the drive roller 33 is pressed tightly against the rubber strip 35 under gravity or pre-tension, and both surfaces have raised stripes, the movement of the rubber strip 35 drives the drive roller 33 to rotate through friction. The rotation of the drive roller 33 drives the rotating shaft 32, which is coaxially fixed to it, to rotate, thereby driving multiple flipping brushes 34 fixed on the rotating shaft 32 to perform circular motion. When the flipping brush 34 rotates to the lower position, its bristles extend into the gaps between the abalone or contact the surface of the abalone, using a gentle pushing force to flip the abalone to the other side. The entire process requires no additional power source such as a motor, utilizing the kinetic energy of the conveyor belt itself to achieve self-driven flipping, which is both energy-saving and avoids the risk of failure of complex electrical controls in humid environments.

[0058] Through the above technical solutions, this application achieves a significant enhancement of the friction and engagement force of the transmission contact surface by using rubber material for both the drive roller 33 and the rubber strip 35, combined with the design of raised surface stripes. This solves the technical problem that traditional smooth rollers are prone to slipping and causing flipping failure in humid environments. At the same time, since the flipping brush 34 is directly driven by the conveyor's kinetic energy, no independent power source is required, which simplifies the device structure and reduces energy consumption. In addition, the soft flipping brush 34 avoids mechanical damage to the delicate surface of the abalone, thereby achieving the technical effect of improving the survival rate and processing quality of abalone while ensuring efficient flipping and sand removal.

[0059] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The slime treatment tank 6 includes a brine collection pipe 61 installed inside the slime treatment tank 6. The brine collection pipe 61 is a closed structure and is connected to the pumping assembly 7. Multiple slime removal filter elements 62 are fixed around the brine collection pipe 61. A slime discharge switch 63 is fixed at the end of the brine collection pipe 61 away from the pumping assembly 7. The slime removal filter element 62 includes a filter element frame 621. A locking platform 622 is fixed at the end of the filter element frame 621. The locking platform 622 is threadedly connected to the brine collection pipe 61. An ultrafiltration membrane 623 is installed on the locking platform 622. An activated carbon filter layer 624 is sleeved on the outside of the filter element frame 621. A filter sleeve 625 is sleeved inside the brine collection pipe 61. The filter sleeve 625 is detachably connected to the brine collection pipe 61. The slime treatment tank 6 is connected to the brine storage tank 1 through a U-shaped pipe.

[0060] The brine collection pipe 61 is a channel structure used to collect and guide the brine containing viscous liquid after preliminary sedimentation treatment. It can be cylindrical, square, or other closed tubular structures adapted to fluid dynamics. In this scheme, the brine collection pipe 61 serves as the core flow channel of the viscous treatment tank 6. One end of it is connected to the pumping assembly 7 to receive the supernatant from the sedimentation treatment tank 5, and the other end is connected to the viscous discharge switch 63 to control the discharge of concentrated waste liquid. This pipe forms a radial filtration relationship with multiple fixed viscous removal filter cartridges 62. Under pressure, the brine to be treated passes through the filter cartridges from the inside or outside of the pipe, achieving separation of brine and viscous liquid.

[0061] The slime removal filter element 62 refers to a filter unit installed around the brine collection pipe 61 to trap slime, organic debris, and small impurities in the water. Multiple slime removal filter elements 62 are distributed around the circumference of the brine collection pipe 61, forming a multi-stage or parallel filtration barrier to increase the effective filtration area and extend the maintenance cycle. The filter element 62 can be connected to the brine collection pipe 61 by radial insertion, lateral screw-in, or flange connection, as long as a tight seal is ensured. The filter element skeleton 621 refers to the basic component that supports the filter medium and maintains the overall structural strength of the filter element. It can be a mesh, porous plate, or spiral wound structure.

[0062] The filter element skeleton 621 is located in the core position inside the mucus removal filter element 62, and is used to support the ultrafiltration membrane 623 and the activated carbon filter layer 624, preventing them from deforming or collapsing under the impact of high-pressure water flow.

[0063] The filter element frame 621 is fixedly connected to the locking platform 622, together forming the main frame of the filter element. Its material can be high-strength plastic, stainless steel, or ceramic, etc. The locking plate 622 refers to the interface component located at the end of the filter element frame 621, used to achieve quick assembly, disassembly, and sealing connection between the filter element and the brine collection pipe 61. In this design, the locking plate 622 and the brine collection pipe 61 are connected by threads. The sludge removal filter element 62 can be secured to the pipe wall or removed from the pipe by rotation. This connection greatly simplifies the filter element replacement and maintenance process. The locking plate 622 is typically also equipped with a sealing ring (not shown in the figure) to ensure watertightness at the connection and prevent short-circuit leakage of unfiltered brine.

[0064] Ultrafiltration membrane 623 refers to a semi-permeable membrane element installed on locking platform 622 for retaining micron- and submicron-sized particles. In this design, ultrafiltration membrane 623 serves as the precision filtration layer of mucus removal filter element 62, primarily used to intercept large molecular proteins, colloidal substances, and tiny suspended solids in abalone mucus. Ultrafiltration membrane 623 works in conjunction with activated carbon filter layer 624; the former is responsible for physical sieving, while the latter is responsible for chemical adsorption. Together, they constitute a composite filtration system.

[0065] The activated carbon filter layer 624 can refer to a porous adsorption material layer that is sleeved on the outside of the filter element frame 621 for adsorbing dissolved organic matter, odors, and some pigments. In this solution, the activated carbon filter layer 624 is wrapped around the outside of the filter element frame 621. When brine passes through this layer, residual mucus components, metabolic waste, and odor molecules are adsorbed and removed, thereby improving the sensory quality of the reused brine.

[0066] The filter sleeve 625 refers to a detachable protective component that is fitted inside the brine collection pipe 61 or mates with the inner wall of the pipe. In this design, the filter sleeve 625 is detachably connected to the brine collection pipe 61. Its material is PP cotton, which allows for preliminary filtration of unprecipitated particulate matter in viscous liquids and brine, thus extending the service life of the ultrafiltration membrane and activated carbon. It also protects the inner wall of the pipe from high-speed water flow erosion and wear. The filter sleeve 625 and the brine collection pipe 61 are detachably connected, and the filter sleeve 625 can be replaced at regular intervals to ensure the smooth flow of brine filtration and improve brine recovery efficiency.

[0067] A U-shaped pipe refers to a guide pipe with a U-shaped bend structure that connects the outlet of the sludge treatment tank 6 to the inlet of the brine storage tank 1. The U-shaped pipe uses its water trap characteristics to form a liquid seal, preventing polluted gases, odors, or incompletely purified wastewater in the sludge treatment tank 6 from flowing back into the clean brine storage tank 1 when the system is shut down or pressure fluctuates, thereby ensuring the safety of the source water quality.

[0068] Through the above technical solution, this application achieves improved mucus treatment efficiency by increasing the effective filtration area per unit volume through the use of a closed brine collection pipe 61 and multiple circumferentially distributed mucus removal filter elements 62. Furthermore, the filter element employs a composite structure of a filter element frame 621, a locking platform 622, an ultrafiltration membrane 623, and an activated carbon filter layer 624, with the locking platform 622 threadedly connected to the pipe, achieving synergistic purification through physical sieving and chemical adsorption. This also makes the disassembly and maintenance of the filter element extremely convenient, solving the problem of difficult replacement of traditional fixed filter elements. The detachable filter sleeve 625 further ensures the cleanliness of the inside of the pipeline and extends the service life of the equipment. The filter sleeve is made of PP cotton, which performs preliminary filtration of the mucus. Since the mucus treatment tank 6 and the brine storage tank 1 are connected by a U-shaped pipe, the backflow path of pollutants is effectively blocked, ensuring the hygiene and safety of the circulating brine. This achieves efficient recycling of water resources and stable and controllable treatment quality during the abalone pretreatment process. When the mucus discharge switch 63 is opened, the mucus filtered inside the brine collection pipe 61 is discharged from the brine collection pipe 61.

[0069] After the mucus removal filter cartridge 62 filters for a period of time, the water pumping component 7 pumps water in reverse to remove the mucus accumulated on the ultrafiltration membrane 623, preventing the mucus removal filter cartridge 62 from becoming clogged. Under the action of the filter cartridge skeleton 621, the loss of activated carbon in the activated carbon filter layer 624 can be reduced, thereby extending the filter cartridge life.

[0070] Refer to Figure 6. Figure 9 , Figure 10 The mucus discharge switch 63 includes a sliding sleeve 631, with an annular partition 632 installed in the middle of the sliding sleeve 631. An inner porous slide plate 633 is slidably installed inside the sliding sleeve 631 near the end of the pumping assembly 7, and an outer porous slide plate 634 is slidably installed inside the sliding sleeve 631 away from the pumping assembly 7. A threaded rod 635 is fixed on the inner porous slide plate 633, and the outer porous slide plate 634 is threadedly connected to the threaded rod 635. The threaded rod 635 passes through... An annular partition 632 is provided with a telescopic spring 636 between the inner porous slide plate 633 and the annular partition 632. A sealing plug 637 is fixed on the outer porous slide plate 634 to block the annular partition 632. A sliding protrusion 638 is provided on the outer edge of the inner porous slide plate 633. A sliding groove 639 is provided on the inner side of the sliding sleeve 631. The sliding protrusion 638 and the sliding groove 639 are slidably connected. Rotating the outer porous slide plate 634 adjusts the pressure of the mucus discharge switch 63.

[0071] Under normal filtration conditions, the slime-containing wastewater in the slime treatment tank 6 enters the sliding sleeve 631 and acts on the surface of the sealing plug 637. At this time, the telescopic spring 636 is in a pre-compressed state, and the rebound force generated by it is transmitted to the outer porous slide plate 634 through the inner porous slide plate 633 and the threaded rod 635. Ultimately, the sealing plug 637 is pressed tightly against the through hole of the annular partition 632, preventing the slime from being discharged. As filtration proceeds, the slime trapped by the filter element 62 increases, causing the pressure in the sliding sleeve 631 near the pumping assembly 7 to gradually increase. When the thrust generated by this pressure exceeds the preset elastic force of the telescopic spring 636, the sealing plug 637 overcomes the spring resistance and slides away from the pumping assembly 7, and the sliding protrusion 638 moves along the sliding groove 639. The movement of the sealing plug 637 pushes the outer porous slide plate 634 to move synchronously through the threaded rod 635, opening the channel, and the concentrated slime is quickly discharged under the action of pressure difference. After discharge, the pressure inside the pipe decreases. When the pressure is lower than the spring force, the telescopic spring 636 pushes the sealing plug 637 to reset, which in turn drives the outer porous slide plate 634 and the sealing plug 637 to re-seal the annular partition 632, completing one automatic sewage discharge cycle. If the starting pressure needs to be adjusted, the operator can rotate the outer porous slide plate 634 to screw it in or out along the threaded rod 635, changing the compression of the telescopic spring 636, thereby setting different opening pressure thresholds.

[0072] This application achieves a self-adjusting pressure switch composed of a sliding sleeve 631, inner and outer multi-hole slide plates 633, outer multi-hole slide plate 634, threaded rod 635, and telescopic spring 636. This solves the technical problem of frequent clogging caused by excessively rapid pressure accumulation at the filter element's front end, requiring manual intervention for unclogging. Thus, it achieves the technical effect of automatically opening and closing the sewage discharge channel according to changes in internal system pressure and flexibly adapting to different water quality conditions through mechanical adjustment. Reference Figure 1 The brine preparation assembly 8 includes a clean water connection pipe 81 for conveying fresh water. A Bernoulli tee pipe 82 is installed on the clean water connection pipe 81. A salt conveying tee pipe 83 is installed at the end of the side pipe of the Bernoulli tee pipe 82. A salt storage tank 84 is installed on the salt storage tank 84. A solenoid valve 85 is installed on the salt storage tank 84. The solenoid valve 85 is electrically connected to the brine concentration detector 12. The solenoid valve 85 is used to control the salt addition speed in the salt storage tank 84. The salt conveying tee pipe 83 is used to mix gas and salt and then convey the mixture to the Bernoulli tee pipe 82 to prevent salt from clogging the side pipe of the Bernoulli tee pipe 82.

[0073] Fresh water flows into the Bernoulli tee pipe 82 via the clean water connection pipe 81, generating negative pressure as it flows through the throat. Simultaneously, the control system opens the solenoid valve 85 based on the feedback signal from the brine concentration detector 12, causing salt particles in the salt storage bin 84 to fall into the salt delivery tee pipe 83 under gravity. During this process, introduced gas (such as compressed air) mixes with the salt particles in the salt delivery tee pipe 83. The airflow disturbance causes the salt particles to suspend and be drawn into the side pipe of the Bernoulli tee pipe 82 by the negative pressure. After entering the high-speed water flow, the salt particles and gas rapidly disperse and dissolve, forming a uniformly concentrated brine, which ultimately flows into the brine storage tank 1. The entire process utilizes fluid dynamics principles to achieve efficient mixing of gas, salt, and water, effectively avoiding the pipe blockage problems that easily occur with traditional dry salt addition methods.

[0074] This application achieves a gas-salt-water three-phase mixed conveying structure by adopting a Bernoulli tee pipe 82 combined with a salt conveying tee pipe 83. By utilizing the negative pressure of water flow to absorb salt and supplementing it with gas disturbance to prevent blockage, the risk of dry salt particles bridging and blocking in the conveying pipeline is completely eliminated. Because a solenoid valve 85 electrically connected to the brine concentration detector 12 is set up, automatic control based on real-time concentration feedback is realized. Therefore, the salt addition speed in the salt storage tank 84 can be accurately controlled, ensuring the long-term stability of the brine concentration and improving the automation level and operational reliability of the entire abalone pretreatment system.

[0075] A method for brine soaking pretreatment of abalone for processing includes the following steps: S1. Brine preparation: Fresh water and salt are mixed using brine preparation components 8 and then transported to brine storage tank 1. The concentration of the prepared brine is 2.5% to 3%. S2. Constant temperature temporary holding: Place the abalone in room temperature water and hold for 10-15 minutes to restore their freshness and reduce stress damage; S3. Abalone placement: Place the abalone into the abalone soaking tank 3, and continuously replenish water to the abalone soaking tank 3 through the spray assembly 2, so that the abalone are submerged in brine; the water sprayed by the spray assembly 2 is cooled to 0-4℃ by the brine cooling assembly 25; S4. Abalone soaking treatment: Place the abalone that has been restored to freshness into the abalone soaking tank 3, control the abalone conveyor belt 4 to rotate at a uniform speed, so that the abalone is moved from the soaking section 41 to the lifting section 42 in 18-25 minutes. During the soaking process, the abalone is turned over once by the abalone turning component 9 to allow the abalone to fully expel sand. S5. Water treatment: The water used to soak the abalone is in a flowing state. When it passes through the sedimentation treatment tank 5, the mud and sand expelled by the abalone are removed. After the mud and sand are removed, it is transported to the mucus treatment tank 6 to remove the mucus. Finally, it is transported to the brine storage tank 1 to realize water circulation. S6. Brine replenishment: After the liquid level in the brine storage tank 1 drops, the brine mixing component 8 delivers the mixed brine to the brine storage tank 1 to replenish the brine and adjust the brine concentration, thus achieving uninterrupted operation.

[0076] The brine replenishment mechanism employs a combination of real-time monitoring and automatic compensation. Through the coordinated control of the brine concentration detector and the brine mixing component, the system achieves continuous and stable operation. When the brine level in the storage tank drops or the brine concentration deviates from the set value, the brine mixing component automatically initiates a brine or water replenishment program, completing the replenishment and concentration adjustment without shutting down the system. This dynamic compensation mechanism not only improves the system's operating efficiency but also ensures the stability of the pretreatment process parameters.

[0077] Through the above technical solutions, this application achieves the following: by adopting an integrated brine preparation component, the brine concentration can be automatically adjusted according to real-time monitoring data, thus solving the problems of poor accuracy and slow response of traditional manual preparation; by setting up a cascade wastewater treatment system, through the synergistic effect of sedimentation treatment tank and mucus treatment tank, the effective separation and removal of impurities of different particle sizes in wastewater is achieved, thus achieving the technical effect that the purified brine can be directly reused; by constructing a complete water circulation system, organically combining each treatment unit, a closed-loop control of the entire process from brine preparation and abalone treatment to wastewater purification and regeneration is formed, thus significantly reducing water consumption and improving system operating efficiency.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.

10. A method for brine soaking pretreatment of abalone, comprising the steps described in claims 1-8 of the brine soaking pretreatment apparatus for abalone processing: S1. Saltwater mixing: Fresh water and salt are mixed using a saltwater mixing unit (8) and then transported to a saltwater storage tank (1). The concentration of the mixed saltwater is 2.5% to 3%. S2. Constant temperature temporary holding: Place the abalone in room temperature water and hold for 10-15 minutes to restore their freshness and reduce stress damage; S3. Abalone placement: Place the abalone into the abalone soaking tank (3), and continuously replenish water to the abalone soaking tank (3) through the spray assembly (2), and submerge the abalone in salt water; the water sprayed by the spray assembly (2) is cooled to 0-4℃ by the salt water cooling assembly (25); S4. Abalone soaking treatment: Place the abalone that has been restored to freshness into the abalone soaking tank (3), control the abalone conveyor belt (4) to rotate at a uniform speed, so that the abalone is moved from the soaking section (41) to the lifting section (42) in 18 to 25 minutes. During the soaking process, the abalone is turned over once by the abalone turning component (9) to allow the abalone to fully expel sand. S5. Water treatment: The water used to soak the abalone is in a flowing state. When it passes through the sedimentation treatment tank (5), the mud and sand expelled by the abalone are removed. After the mud and sand are removed, it is transported to the mucus treatment tank (6) to remove the mucus. Finally, it is transported to the brine storage tank (1) to realize water circulation. S6. Brine replenishment: After the liquid level in the brine storage tank (1) drops, the brine mixing component (8) transports the mixed brine to the brine storage tank (1) to replenish the brine and adjust the brine concentration, so as to achieve non-stop operation.
