Description

Technical Field

[0001] This application relates to the field of aquaculture feeding systems, and more specifically, to an automatic liquid feed feeding system. Background Technology

[0002] Scallops and oysters, among other bivalve mollusks, are generally filter feeders, primarily consuming single-celled algae. Therefore, the production and feeding of single-celled algae feed is a crucial foundational task in bivalve mollusk rearing, directly impacting the success or failure of the rearing process. In mollusk rearing, single-celled algae feed is typically cultivated in seawater with the addition of nutrients in feed culture tanks, making it a liquid feed. Traditional mollusk rearing farms usually rely on manual feeding using a stopwatch. This process is cumbersome, lacks accurate control over feeding time, and carries the risk of missed or repeated feedings, which can directly lead to rearing failure. Furthermore, manual feeding typically involves keeping the feed pump constantly running, and moving the feed tube between different rearing tanks often results in significant feed waste. Therefore, a smart and systematic feeding system is urgently needed to solve the challenges in feeding mollusk rearing. Utility Model Content

[0003] In view of this, the purpose of this application is to provide an automatic liquid bait feeding system. The system, through a "central control + hierarchical execution" architecture, achieves automated management of stable pressure, self-cleaning pipelines, and precise feeding in designated areas, significantly improving feeding efficiency and reliability. It automatically controls the feeding valve to pump qualified bait into the feeding pipeline and maintains constant pressure to ensure accurate feeding. It enables timed / group precise feeding, allowing users to set feeding batches, feeding amounts, feeding times, etc., to achieve unmanned precise feeding. It also automatically controls the water valve and cleaning valve to achieve automatic pipeline cleaning.

[0004] The objective of this application is achieved through the following technical solution: An automatic liquid feed feeding system includes a central controller, a feed pump, a booster pump, a constant pressure controller, a feed tank valve group control box, a feed sub-control box, a feed valve, a clear water valve, a feed valve, a cleaning valve, and connecting pipelines. The central controller is connected to the constant pressure controller, the feed tank valve group control box, the feed sub-control box, and the feed pump. The constant pressure controller controls the booster pump to start. The booster pump is connected to the feed pump. The central controller controls the feeding amount and feeding time. The inlet of the feed pump is connected to the feed tank or clear water tank and then to the connecting pipelines via the feed valve or clear water valve. The outlet of the feed pump is connected to the nursery tank via the feed valve and the connecting pipelines. The cleaning valve is located at the end of the outlet connecting pipelines. The feed tank valve group control box controls the opening of the feed valve and the clear water valve, allowing feed to be drawn from the feed tank or clear water to be drawn from the clear water tank. The feed sub-control box controls the opening of the feed valve and the cleaning valve.

[0005] Preferably, the constant pressure controller includes several pressure sensors, which are located on the inner wall of the connecting pipe. The pressure sensors are used to monitor the pressure data in the connecting pipe and send control commands to the booster pump. The booster pump pressurizes the medium delivered by the feed pump to ensure stable pressure throughout the entire feed process.

[0006] Preferably, the inlet of the feeding pump is connected to the feeding pool via a feeding valve and a connecting pipe, or to the clear water pool via a clear water valve and a connecting pipe. The outlet of the feeding pump is connected to the seedling pool via a feeding valve and a connecting pipe. A cleaning valve is installed at the end of the outlet pipe. The feeding valve and the clear water valve are controlled by the feeding pool valve group control box. When they are turned on, the feeding pump draws in feed or draws in clear water for cleaning. The feeding valve and the cleaning valve are controlled by the feeding sub-control box. When they are turned on, they feed the target seedling pool or clean the pipeline.

[0007] Preferably, the connecting pipeline includes an inlet pipeline and an outlet pipeline, located at the inlet and outlet ends of the feeding pump, respectively. The inlet pipeline is connected to the feeding pool or the clear water pool through a feeding valve or a clear water valve, and the outlet pipeline is connected to the seedling pool through a feeding valve. A cleaning valve is installed at the end of the outlet pipeline.

[0008] Preferably, multiple feeding control boxes are provided, which are used to control the opening of the feeding valve or the cleaning valve.

[0009] Preferably, the feeding valve, water valve, baiting valve, and cleaning valve are all electrically controlled valves.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The constant pressure controller monitors the pressure of the feeding system in real time and sends control commands to the booster pump; the booster pump pressurizes the medium delivered by the feeding pump to ensure stable pressure throughout the feeding process, thereby ensuring uniform feed flow and accurate delivery. By monitoring and adjusting the pressure of the feeding system, it ensures stable pressure during feed delivery. 2. The central controller, as the "brain" of the system, coordinates and plans the entire process, including feeding, pressure control, and pipeline cleaning, to achieve automated feeding management, such as setting feeding time, feeding amount, and cleaning cycle. 3. Through a "centralized control + hierarchical execution" architecture, the system achieves automated management of stable pressure, self-cleaning pipelines, and precise feeding in designated areas, significantly improving feeding efficiency and reliability. It automatically controls the feeding valve to pump qualified bait into the feeding pipeline and maintains constant pressure to ensure accurate feeding. Timed / group precise feeding allows setting feeding batches, feeding amounts, feeding times, etc., to achieve unmanned precise feeding. 4. When the system needs to clean the pipeline, the central controller controls the opening of the clean water valve and the cleaning valve. Clean water flows from the clean water tank into the main pipeline and branch pipelines to flush the pipeline. The flushed wastewater is discharged from the cleaning valve, realizing the self-cleaning of the pipeline and avoiding bait residue contamination or pipeline blockage. Attached Figure Description

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0013] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of this application may have fewer components, other components not shown in the drawings, different components, differently arranged components, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0014] This application discloses an automatic liquid feed system, comprising a central controller, a feed pump, a booster pump, a constant pressure controller, a feed tank valve group control box, a feed sub-control box, a feed valve, a clear water valve, a feed valve, a cleaning valve, and connecting pipelines. The central controller is connected to the constant pressure controller, the feed tank valve group control box, the feed sub-control box, and the feed pump. The constant pressure controller controls the booster pump to start, and the booster pump is connected to the feed pump. The central controller controls the feeding amount and feeding time. The inlet of the feed pump is connected to the feed tank or clear water tank through the feed valve or clear water valve and connecting pipelines. The outlet of the feed pump is connected to the nursery tank through the feed valve and connecting pipelines. The cleaning valve is located at the end of the outlet connecting pipelines. The feed tank valve group control box controls the opening of the feed valve and the clear water valve, allowing feed to be drawn from the feed tank or clear water to be drawn from the clear water tank. The feed sub-control box controls the opening of the feed valve and the cleaning valve.

[0015] Specifically, the constant pressure controller includes several pressure sensors located on the inner wall of the connecting pipeline. These pressure sensors monitor pressure data within the connecting pipeline and send control commands to the booster pump. The booster pump pressurizes the medium delivered by the feed pump, ensuring stable pressure throughout the entire feed supply process. The specific steps include: pressure detection: real-time acquisition of pressure data in the connecting pipeline using the matching pressure sensors; signal comparison: comparison of the acquired actual pressure value with the user-set "target pressure value" to determine if there is a deviation; automatic adjustment: based on the direction of the deviation, sending a control signal to the booster pump to adjust the output: if the pressure is too low, increasing the booster pump output, starting the booster pump, and increasing the medium supply; if the pressure is too high, decreasing the booster pump output, stopping the booster pump, and reducing the medium supply.

[0016] Specifically, there are multiple seedling ponds, and connecting pipelines are connected to the seedling ponds in sequence to increase the scale of breeding. Feed is simultaneously delivered to multiple seedling ponds through the connecting pipelines.

[0017] The feed pump's inlet is connected to the feed pool or clean water pool via a feed valve or clean water valve and a connecting pipe. The feed pump's outlet is connected to the seedling pool via a feeding valve and a connecting pipe. A cleaning valve is installed at the end of the outlet pipe. The feed valve and clean water valve are controlled by the feed pool valve group control box. When they are turned on, the feed pump draws in feed or clean water for cleaning. The feeding valve and cleaning valve are controlled by the feeding sub-control box. When they are turned on, they feed the target seedling pool or clean the pipeline.

[0018] Specifically, the connecting pipeline includes an inlet pipeline and an outlet pipeline, located at the inlet and outlet ends of the feed pump, respectively. The inlet pipeline is connected to the feed pool or clear water pool through a feed valve or clear water valve, and the outlet pipeline is connected to the seedling pool through a feed valve. A cleaning valve is installed at the end of the outlet pipeline.

[0019] The system includes multiple feeding control boxes, which work together to control the opening of feeding valves. Each feeding control box manages multiple seedling ponds and can provide timed / grouped precise feeding. Feeding batches, feeding amounts, and feeding times can be set to achieve unmanned and precise feeding. The feeding control boxes also work together to control the opening of cleaning valves for cleaning pipelines.

[0020] Specifically, the feed valve, water valve, feeding valve, and cleaning valve are all electrically controlled valves.

[0021] In use, this invention employs a central controller to operate the feeding pump, which delivers liquid feed to the nursery pond via connecting pipes. The feed tank valve control box controls the opening of the feeding valve. A constant pressure controller monitors the pressure of the feeding system in real time and sends control commands to the booster pump. The booster pump pressurizes the medium delivered by the feeding pump, ensuring stable pressure throughout the feeding process. This guarantees uniform feed flow and accurate dispensing. By monitoring and adjusting the pressure of the feeding system, stable pressure is ensured during feed delivery. After feeding is completed, the feeding valve and the feeding dispensing valve are closed, and the clean water valve and the cleaning valve are opened. The feeding pump then pumps clean water from the cleaning tank to clean the connecting pipes, preventing liquid feed from remaining and avoiding bacterial growth. After cleaning, the cleaning valve is closed.
