Description

Technical Field

[0001] This invention belongs to the field of aquaculture equipment technology, and specifically relates to a feeding bin for fully fermented aquatic feed. Background Technology

[0002] Fully fermented feed refers to feed in which all raw materials are fermented, allowing bacteria or yeast to break down all carbohydrates, thereby improving nutritional value and enhancing digestibility and absorption. Fully fermented aquatic feed, rich in active probiotics, demonstrates significant advantages in improving gut health, boosting immunity, reducing disease incidence, and minimizing water pollution in farmed animals, making it an important development direction for the industry. However, the unique physical and biological characteristics of this type of feed present systemic challenges in the feeding process that traditional equipment cannot overcome. The core value of fully fermented feed lies in its highly active probiotics. Most existing feeders are open or semi-open designs. During the temporary storage and transportation of feed before feeding, the feed is exposed to room temperature and oxygen-rich air for a long time, which leads to a rapid decline in the activity of anaerobic probiotics and a large proliferation of aerobic putrefactive bacteria, resulting in serious deterioration of feed quality and loss of its core function.

[0003] Fermented feed is characterized by high viscosity and a tendency to clump, easily adhering to the bin walls and forming "arches" at the outlet. Existing technologies that use stirring to prevent arching involve high shear forces, which can easily damage the microbial community structure. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding bin for fully fermented aquatic feed.

The upper outer wall of the discharge pipe is provided with a flange, and an annular air chamber is concentrically arranged inside the flange. An air chamber hole communicating with the discharge pipe is opened on the outer wall of the annular air chamber. A valve is provided on the discharge pipe and below the air chamber hole. It also includes a gas tank containing inert gas, an air inlet pipe connected to the gas tank is provided on the top of the silo, an exhaust pipe is provided on the outer wall of the silo and above the feed inside the silo, and a safety valve is also provided on the top of the silo.

Valves are provided on the exhaust pipe and on both sides of the first branch pipe, and on both the first branch pipe and the second branch pipe.

[0006] Furthermore, a vibrator is installed on the outer wall of the conical opening.

[0007] Furthermore, a gas drying unit is connected to the main gas pipe. The gas drying unit directly adopts existing technology and will not be described in detail here. Alternatively, a gas drying unit with a cooling function can also be selected.

[0008] Furthermore, it also includes a screw conveyor disposed below the discharge pipe, the inlet of the screw conveyor being connected to the discharge pipe, and the discharge port of the screw conveyor being provided with a conveying pipe, the conveying pipe including a horizontal section communicating with the discharge port and a horizontal section facing the feeding area. Screw conveyor Furthermore, a second flange is concentrically provided on the outer wall of the horizontal section near the vertical section, and an annular air groove communicating with the horizontal section of the conveying pipe is opened inside the second flange. At least one tangential air inlet is provided on the outer wall of the annular air groove.

The tangential air inlet is connected to the main air pipe through a branch pipe three, and a valve is provided on the branch pipe three.

[0009] Furthermore, a circular hole is opened on the top plate of the cylinder, and a hollow circular boss is concentrically arranged on the cylinder and located outside the circular hole. A feeding port and a cover plate for sealing the feeding port are provided on the boss. Both the safety valve and the air intake pipe are mounted on the circular boss. The exhaust pipe is mounted on the cylinder.

[0010] Furthermore, the flexible inner liner is made of food-grade silicone.

[0011] Furthermore, a flange is fixedly provided on the lower part of the outer wall of the cylinder, and a flange is provided on the upper part of the outer wall of the conical bucket. An annular groove is concentrically provided on the upper end face of the flange. The lower part of the outer wall of the conical hopper is provided with flange three, the upper part of the outer wall of the discharge pipe is provided with flange four, the lower end face of flange four is concentrically provided with annular groove two, the upper end of the flexible inner liner is turned outward from the upper end of the conical hopper and is set in the annular groove one, and the lower end of the flexible inner liner is turned outward from the lower end of the conical hopper and is set in the annular groove two. The flanges are fixed together by bolts, and the flexible inner liner is also fixed by bolts.

[0012] Furthermore, a branch pipe four for exhaust is provided on the main gas pipe, and a valve is provided on the branch pipe four. The branch pipe four is located before the gas drying unit. By opening the valve on the branch pipe four, the gas in the hopper can be directly discharged into the air.

[0013] Furthermore, compression strips for pressing the flexible inner liner can be provided in the second and first annular grooves.

[0014] Furthermore, an installation plate is fixedly provided on the outer wall of the cylinder, and the air pump and the gas drying unit are both mounted on the installation plate. Several support legs are fixedly provided on the outer wall of the cylinder, and the installation plate and the conveying pipe are located on the same side of the cylinder.

[0015] Furthermore, the outer casing of the screw conveyor is fixed to the supporting leg. A protective railing is provided along the outer edge of the top of the cylinder.

[0016] Furthermore, it also includes gas sensors (an oxygen sensor for detecting oxygen and a corresponding inert gas sensor) for detecting the gas composition within the chamber, a pressure sensor for detecting the gas pressure within the chamber, a temperature sensor for detecting the temperature within the chamber, and a humidity sensor for detecting the humidity within the chamber. The controller for receiving and processing the signals from each sensor employs existing technology and will not be described in detail here. The specific models of each sensor are selected based on existing technology according to the actual situation and will not be described in detail here.

[0017] Furthermore, two vibrators are symmetrically installed.

[0018] Furthermore, the gas cylinder can be a nitrogen cylinder.

[0019] Furthermore, the cylinder can adopt a sandwich structure, which can improve the heat preservation effect.

[0020] Furthermore, all connections between the various parts in this application must be sealed, such as between the cover plate and the feed port, and at flange connections, to reduce gas leakage.

[0021] Furthermore, the inner diameter of the air chamber pores is generally smaller than that of the feed pellets, typically 0.1-0.3 mm.

[0022] How to use: 1. Feed preservation stage: The fermented aquatic feed is loaded into the chamber, and the cover is closed and sealed. The pump is started to extract some of the air from the chamber. Then, the inert gas source and corresponding valve are opened to fill the chamber with inert gases such as nitrogen until the pressure sensor and oxygen sensor detect that the chamber has reached the set pressure and low oxygen concentration (e.g., <3%).

[0023] Based on feedback from the humidity sensor, the air pump is activated periodically to extract the gas from the chamber, remove moisture through a cold gas drying unit, and then reinject the gas into the chamber to continuously keep the gas dry.

[0024] Based on feedback from the pressure sensor, when the pressure deviates from the set range due to a slight leak, the gas tank is opened to replenish a small amount of gas.

[0025] Based on feedback from the oxygen sensor, when the oxygen concentration deviates from the set range, the gas tank is opened to provide a small amount of supplemental gas.

[0026] 2. Application of annular air grooves: Open the valve on branch pipe three to allow the inert gas in the silo to pass through the air pump, main air pipe, gas drying unit, and branch pipe three into the tangential air inlet and be injected tangentially (annular air groove). The gas forms a stable lubricating air curtain on the inner wall of the horizontal section of the conveying pipe, which greatly reduces the conveying resistance, prevents pipe blockage, and further reduces the mechanical shearing of the feed by the pipe wall.

[0027] Start the screw conveyor to push the feed into the conveyor pipe that has been lubricated by an air curtain, and then transport it to the feeding point.

[0028] The air curtain gas is eventually discharged into the aquaculture water along with the feed. In addition, the air curtain gas needs to be replenished in real time through gas tanks during discharge.

[0029] 3. Application of the annular air chamber: Open the valve on branch pipe two to allow the inert gas inside the silo to pass through the air pump, main air pipe, gas drying unit, and branch pipe two into the annular air chamber. The gas then exits through the air chamber's vents into the discharge pipe (which is sealed by a valve). The gas then enters the flexible inner liner, forming an extremely thin air film between the feed and the silo wall, causing the feed adhering to the wall to separate. After the intervention is complete, the system automatically resumes normal conveying, achieving non-mechanical shearing arch breaking.

[0030] After a certain period of time, open the valve on the discharge pipe to start the screw conveyor and transport the feed. At this time, the gas in the second branch pipe should be discharged normally, and it should be replenished in real time through the gas tank.

[0031] When using the annular air trough or moving the annular air chamber, the vibrator can be activated simultaneously. The vibration generated by the vibrator causes the conical hopper and flexible inner liner to shake, which helps to transport feed and break up arches.

[0032] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: Creating a low-oxygen, inert gas environment within the storage chamber inhibits the growth of aerobic putrefactive bacteria at its source, providing near-ideal temporary storage conditions for anaerobic probiotics, reducing the rate of activity decay of aerobic probiotics, and greatly ensuring the quality of the feed.

[0033] By using a flexible inner liner in conjunction with a vibrator and an air film formed on the inner wall of the liner, a non-mechanical shearing method is used to peel off the material adhering to the wall, thereby breaking up the arch while reducing damage to the bacterial colony.

[0034] By introducing tangential swirling gas into the conveying pipe, a wall-adhering air curtain is formed, reducing the conveying resistance of highly viscous feed in the pipeline. Attached Figure Description

[0051] Two vibrators 14 are installed symmetrically.

[0052] Gas cylinder 4 can be a nitrogen cylinder 4.

[0053] The cylinder 101 can adopt a sandwich structure, which can improve the heat preservation effect.

[0054] All connections between the various parts in this application must be sealed, such as between the cover plate 104 and the feed port, and at the flange connection, to reduce gas leakage.

[0055] The inner diameter of the air chamber pore 204 is generally smaller than that of the feed pellet, usually 0.1-0.3 mm.

[0056] How to use: 1. Feed preservation stage: Fill the fermented aquatic feed into chamber 1, close and seal the cover 104. Start the pump to extract some air from the chamber, then open the inert gas source and corresponding valve to fill the chamber with inert gases such as nitrogen until the pressure sensor and oxygen sensor detect that the chamber has reached the set pressure and low oxygen concentration (e.g., <3%).

[0057] Based on feedback from the humidity sensor, the air pump 5 is activated periodically to extract the gas from the chamber. After the gas passes through the cold gas drying unit 6 to remove moisture, it is then reinjected into the chamber to continuously keep the gas dry.

[0058] Based on feedback from the pressure sensor, when the pressure deviates from the set range due to a slight leak, the gas tank 4 is opened to replenish a small amount of gas.

[0059] Based on feedback from the oxygen sensor, when the oxygen concentration deviates from the set range, gas tank 4 is opened to provide a small amount of supplemental gas.

[0060] 2.

The gas forms a stable lubricating air curtain on the inner wall of the horizontal section 1102 of the conveying pipe 11, which greatly reduces the conveying resistance, prevents pipe blockage, and further reduces the mechanical shearing of the feed by the pipe wall.

[0061] Start the screw conveyor 3 to push the feed into the conveyor pipe 11, which has been lubricated by an air curtain, and transport it to the feeding point.

[0062] The air curtain gas is eventually discharged into the aquaculture water along with the feed. In addition, the air curtain gas needs to be replenished in real time through gas tank 4 during discharge.

The gas is then ejected from the air chamber vent 204 into the discharge pipe 2 (which is sealed by a valve). The gas then enters the flexible inner liner 13, forming an extremely thin air film between the feed and the silo wall, causing the feed adhering to the wall to separate. After the intervention is completed, the system automatically resumes normal conveying to achieve non-mechanical shearing arch breaking.

[0064] After a certain period of time, open the valve on the discharge pipe 2 to start the screw conveyor 3 to transport the feed. At this time, the gas on branch pipe 2 9 should be discharged normally, and it should be replenished in real time through the gas tank 4.

[0065] When the annular air trough 1201 is in use or the annular air chamber 203 is in motion, the vibrator 14 can be activated simultaneously. The vibration generated by the vibrator 14 causes the conical hopper 102 and the flexible inner liner 13 to shake, which assists in the conveying and arch breaking of feed.
