Description

Technical Field

[0001] This utility model relates to the field of premixing technology for marine aquaculture agents, and in particular to a premixing structure for administering marine aquaculture agents. Background Technology

[0002] In modern mariculture, water quality management is one of the core factors determining the success rate of aquaculture. To control diseases and regulate the aquatic environment (such as pH, dissolved oxygen, and ammonia nitrogen), various agents, including disinfectants, probiotics, nutrients, and antibiotic alternatives, need to be added to the aquaculture water regularly. However, traditional methods of agent application generally have the following problems: 1. Uneven mixing leads to imbalance in drug efficacy: Most fish farms still use manual or simple mechanical stirring to premix the drug solution. Due to the wide variety of drugs, large density differences, and slow dissolution speed, it is very easy for the local concentration to be too high while the distant area is ineffective. This not only wastes resources, but may also cause fish poisoning or increased drug resistance. 2. Risk of secondary contamination due to sedimentation: If the prepared drug solution is not used promptly, sedimentation and stratification are likely to occur during storage, especially for compound agents containing suspended particles or high-density components. If the solution is not thoroughly remixed before reuse, it will severely affect the accuracy of application and the therapeutic effect. 3. Low stirring efficiency, high energy consumption and easy damage: Single-drive mechanical stirring systems often have a fixed speed and limited stirring range. When faced with viscous or high solid content liquids, the efficiency drops sharply. Long-term operation will also aggravate equipment wear and increase maintenance costs.

[0003] To address these issues, we propose a premixed structure for administering medications in marine aquaculture. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a premixed structure for the administration of pharmaceuticals in marine aquaculture.

The second gas delivery structure includes fixed pipes fixed on both sides of the lower end of the storage tank. Multiple nozzles are connected to the fixed pipes at equal intervals. One end of each nozzle penetrates the side wall of the storage tank and extends into the storage tank. One end of each of the two fixed pipes is connected to a connecting pipe. The first gas supply structure includes a second gas supply pipe connected to one side of the lower end of the mixing box. One end of the second gas supply pipe is connected to a first gas supply pipe. One end of the first gas supply pipe is connected to a connecting pipe. The other end of the first gas supply pipe is connected to a gas pump. The gas pump is installed on the upper end of the base plate. A first electric valve is installed on both the first gas supply pipe and the second gas supply pipe.

[0006] Preferably, the stirring device includes a drive motor installed on one side of the mixing tank and the storage tank, and a rotating rod is connected to the end of the output shaft of the drive motor. Multiple rectangular stirring blades are fixed at equal intervals around the circumference of the rotating rod.

[0007] Preferably, the bottom of the mixing tank is connected to an installation pipe, the lower end of which is connected to the upper middle part of the storage tank, and a second electric valve is provided on the installation pipe.

[0008] Preferably, the mixing box has a dispensing port at the upper center.

Regular pneumatic output and gentle stirring during the settling period solve the problem of drug solution separation caused by long-term storage; 3. The power consumption of pneumatic stirring is much lower than that of mechanical operation at all times. It is only activated when necessary, which greatly improves the energy saving rate. 4. Mechanical stirring provides directional shear force to break up agglomerated particles, while pneumatic stirring achieves full-area disturbance, eliminating dead corners. It is especially suitable for large-volume containers, improving the quality and thoroughness of stirring. In summary, this invention shortens mixing time and improves the quality and thoroughness of mixing through the synergistic effect of pneumatic and mechanical stirring, solving the problem of drug liquid separation caused by long-term storage. At the same time, it greatly improves energy efficiency and enhances the thoroughness and practicality of drug premixing. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figs. 1-3 A premixed structure for administering pharmaceuticals for marine aquaculture includes a base plate 101, a storage tank 501 fixed to the upper end of the base plate 101, a second gas supply structure connected to both sides of the lower end of the storage tank 501, a mixing box 301 connected to the upper end of the storage tank 501, a first gas supply structure connected to one side of the lower end of the mixing box 301, and a stirring device installed on one side of the mixing box 301 and the storage tank 501. The bottom of the mixing box 301 is designed as an inverted cone shape, with the installation pipe 303 located at the lowest point, and the inner wall is mirror polished to minimize residue. The second gas transmission structure includes fixed pipes 205 fixed on both sides of the lower end of the storage tank 501. Multiple nozzles 206 are connected at equal intervals on the fixed pipes 205. One end of the nozzle 206 penetrates the side wall of the storage tank 501 and extends into the storage tank 501. One end of the two fixed pipes 205 is connected to a connecting pipe 207. The first gas supply structure includes a second gas supply pipe 204 connected to the lower side of the mixing box 301. One end of the second gas supply pipe 204 is connected to a first gas supply pipe 202. One end of the first gas supply pipe 202 is connected to a connecting pipe 207. The other end of the first gas supply pipe 202 is connected to a gas pump 201. The gas pump 201 is installed on the upper end of the base plate 101. A first electric valve 203 is installed on both the first gas supply pipe 202 and the second gas supply pipe 204. The mixing equipment includes a drive motor 401 installed on one side of the mixing tank 301 and the storage tank 501. The drive motor 401 is a variable frequency speed control servo motor. The PLC calls a preset program according to the type of reagent. In the initial stage, high-speed shearing (800-1200 rpm) breaks up agglomerates. In the middle stage, medium-speed circulation (500-600 rpm) promotes diffusion. In the final stage, low-speed homogenization (300 rpm) eliminates eddies and avoids excessive foam generation. The output shaft of the drive motor 401 is connected to a rotating rod 403. Multiple rectangular stirring blades 402 are fixed at equal intervals around the rotating rod 403. The rectangular stirring blades 402 enhance the shear force and work together with the air lifting effect to achieve efficient mixing. The bottom of the mixing tank 301 is connected to the mounting pipe 303, and the lower end of the mounting pipe 303 is connected to the upper middle part of the storage tank 501. The mounting pipe 303 is equipped with a second electric valve 304. Before closing the second electric valve 304, the gas pump 201 is briefly started to inject short-term high-pressure gas (0.1–0.2MPa) into the bottom of the mixing tank 301, forming a reverse thrust to push the residual liquid out. The mixing box 301 has a feeding port 302 at the upper middle part, and the feeding port 302 is equipped with a rotating cover with a filter screen; Both the mixing tank 301 and the storage tank 501 are connected to an exhaust valve 504 on one side of the upper end. The exhaust valve 504 is a differential pressure control valve. When the internal pressure exceeds the set value (such as 1.2 times the atmospheric pressure), it will automatically open to release pressure and will automatically close when it is lower than the safety limit to prevent external pollutants from flowing back in. Mounting holes 102 are provided at the four corners of the base plate 101. A sensor group 502 is installed at the lower end of the storage tank 501. The sensor group 502 includes turbidity, density and temperature sensors. In this invention, during premixing: 1. Initial feeding stage: Users add solid medicine or concentrated liquid to mixing tank 301 through inlet 302, and at the same time connect clean water or dilution water. The water volume can be adjusted according to needs. At this time, the second electric valve 304 is closed to prevent the medicine from flowing into the storage tank in advance, and the exhaust valve 504 is opened to release the air pressure generated by adding materials and avoid splashing. 2. Enhanced Mixing Stage: The drive motor 401 is started, which drives the rotating rod 403 and the rectangular stirring blade 402 to rotate in the mixing chamber. The rectangular stirring blade design increases the shear force and flow field disturbance range, which is especially suitable for viscous liquids or insoluble substances. Simultaneously, the gas pump 201 is started, and microbubbles are sprayed into the bottom of the mixing chamber 301 through the first gas supply pipe 202 → connecting pipe 207 → second gas supply pipe 204. As the bubbles rise, they form a "gas lift effect", which drives the liquid to circulate up and down and generate strong internal convection. The first electric valve 203 precisely controls the gas flow rate to avoid excessive foaming from affecting the mixing stability. The two work together to complete the mixing task that usually takes more than 15 minutes in 3-5 minutes, improving efficiency by more than 60%. 3. Tiered transfer stage: Once mixing is complete and confirmed after a delay, the PLC controller issues a command to open the second electric valve 304. The well-mixed liquid flows by gravity through the installation pipe 303 into the storage tank 501. After discharge, the valve automatically closes, ready for the next replenishment. 4. Static maintenance phase: During the temporary storage of the drug solution, sensor group 502 continuously monitors the state of the bottom of the storage tank, including changes in turbidity (to determine whether precipitation has begun), density gradient (to reflect the stratification trend), and temperature fluctuations (affecting the dissolution balance). The system automatically wakes up at set time intervals (every 2 hours) or when an abnormality is detected, and restarts the gas pump 201 and the second gas delivery structure to inject a short-term pulsed airflow into the bottom of the storage tank. At the same time, the stirring equipment on the storage tank side is started to perform brief low-speed stirring to achieve "intermittent disturbance," which effectively suppresses particle sedimentation and maintains the homogeneity of the drug solution. All operations do not require manual intervention, greatly reducing the maintenance burden.

[0017] Pulse-type airflow speed setting three-level response: Level 1 (slight stratification): Only bottom pulse aeration is activated (lasts 10 seconds, intervals of 5 minutes); Secondary stage (local sedimentation): Simultaneously start low-speed stirring (200 rpm) and aeration; Level 3 (large-area sedimentation): Start full-power stirring + continuous aeration for 30 seconds, then execute the self-diagnosis process.

[0018] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
