Description

Technical Field

[0001] This utility model applies to the field of aquaculture equipment and provides a moisture-proof storage device for aquaculture feed. Background Technology

[0002] With the continuous development of modern aquaculture technology, fish farming has gradually achieved large-scale indoor culture. This method not only increases stocking density and production efficiency, but also effectively controls water quality and environmental conditions, thereby ensuring the healthy growth of fish and the profitability of the farming.

[0003] Meanwhile, the feeding methods in fish farming have also undergone a transformation from manual feeding to automated feeding. Now, most fish farms have implemented timed and quantitative feed delivery, and process it on a large scale and in a standardized manner using advanced equipment. This change has not only improved feed utilization and reduced waste, but also ensured the nutritional balance and growth rate of the fish.

[0004] However, in indoor aquaculture ponds, most farms still rely on traditional feed storage tanks. However, due to the high humidity of the indoor aquaculture environment, the feed in these tanks often becomes damp and moldy. This moisture has a significant impact on feed quality, potentially leading to nutrient loss, disease transmission, and ultimately affecting fish growth and health, while also posing considerable challenges to aquaculture management. Therefore, effectively solving the problem of moisture-proof feed storage has become a key issue in improving aquaculture efficiency and management effectiveness. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide a moisture-proof storage device for aquaculture feed, thereby solving the problems mentioned in the background art. The device includes a tank with a material storage chamber inside. The top of the tank is equipped with a loading port, a motor, an air valve, and an air extraction port. A vacuum device is connected to the external air extraction port via a pipe. A sealing cover is hinged to the loading port. The output end of the motor is fixedly connected to a rotating shaft passing through the inside of the tank, and the rotating shaft is equipped with a stirring blade. A discharge port is installed at the bottom of the tank, and a solenoid valve is installed on the discharge port.

[0006] The inner wall of the tank is separated by a partition with several vertical air passages; a vent panel is provided on the side of the air passages near the inside of the tank; the top of the tank is provided with a first air port corresponding to each of the air passages, and the first air port is connected to an air supply device through a pipe.

[0007] Furthermore, the partition constituting the air passage is provided with a sliding groove, the ventilation panel is slidably connected inside the sliding groove, and the partition is provided with a number of fixing holes corresponding to the sliding groove.

[0008] Furthermore, the ventilation panel includes a support mesh and a baffle mesh, which are respectively located on the side near the air passage and the side near the material chamber.

[0009] Furthermore, the exterior of the air passage is provided with a transition surface that smoothly transitions with the inner sidewall of the tank.

[0010] Furthermore, a safety valve is fixedly connected to the top of the tank.

[0011] Furthermore, a support frame is fixedly connected to the bottom of the tank.

[0012] Furthermore, an observation port is fixedly connected to the top of the tank.

[0013] This invention fundamentally prevents feed spoilage by removing moisture from the feed chamber. Secondly, the motor-driven stirring blades effectively prevent feed caking, ensuring the material's looseness and uniform drying. Inert gas introduced through the air duct and ventilation panel further creates a low-oxygen preservation environment, complementing the vacuum drying process.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0025] See Figure 1-5 The purpose of this utility model is to provide a moisture-proof storage device for aquaculture feed, including a tank 1. The tank 1 has a material chamber 100 for storing feed inside. The top of the tank 1 is equipped with a feeding port 11, a motor 21, an air valve 13, and an air extraction port 16. The air extraction port 16 is externally connected to a vacuum device through a pipe. The air valve 13 is an electromagnetic switch valve, which can be opened or closed under control. Its electrical connection is controlled by an external control system, which can realize gas exchange between the inside and outside of the tank 1.

[0026] Specifically, the vacuum device can evacuate air through the evacuation port 16 to maintain a certain vacuum inside the device, removing the relatively humid air and keeping the contents dry. When external loading or unloading is required, air can be introduced into the device through the air valve 13 to restore the pressure balance inside and outside.

[0027] The output end of the motor 21 is oriented downwards, and a rotating shaft 22, which passes through the inside of the tank 1, is fixedly connected to the bottom of the output end. A stirring blade 23 is mounted on the rotating shaft 22. The stirring blade 23 rotates slowly under the drive of the motor, thereby agitating the feed inside the equipment and preventing clumping. Understandably, the motor 21 is often used in conjunction with a reducer in actual use; that is, the power output end of the motor 21 is first connected to the reducer, and the power output end of the reducer is then connected to the rotating shaft 22.

[0028] The filling port 11 is used to fill the inside of the tank 1. A sealing cover is hinged to the filling port 11. The sealing cover can be opened or closed, and at the same time, it is closed on the filling port 11 by a locking mechanism to ensure the airtightness of the tank 1.

[0029] A discharge port 12 is installed at the bottom of the tank body 1, and a solenoid valve 121 is installed on the discharge port 12. The solenoid valve 121 is an electromagnetic sealing valve; the solenoid valve 121 can control the opening or closing of the discharge port 12. When the solenoid valve 121 is open, the feed inside can be discharged from the discharge port 12, and the opening time of the solenoid valve 121 can control the amount of feed discharged.

[0030] Several vertical air passages 10 are separated by partitions on the inner wall of the tank body 1; specifically, the air passages 10 are arranged vertically along the inner wall of the tank body 1. A vent panel 3 is provided on the side of the air passage 10 closest to the interior of the tank body 1; the top of the tank body 1 is provided with a first air port 101 corresponding to each of the air passages 10. The first air port 101 is connected to a gas supply device through a pipe. The gas supply device can supply inert gas or dry gas, etc., into the air passages 10.

[0031] In summary, the overall operation of the moisture-proof storage device for aquaculture feed provided by this utility model is as follows:

[0032] Example 1

[0033] In one usage method: First, the operator loads the feed through the loading port 11 and seals the hatch. Then, a vacuum device extracts air from the material chamber 100 inside the tank 1 through the air extraction port 16, creating and maintaining a vacuum. This process effectively reduces the internal pressure, allowing moisture inside and between the feed particles to evaporate more easily and be quickly removed under low pressure, fundamentally eliminating the humid air environment that causes feed spoilage. During this process, the feed inside can be turned over by the stirring blades 23. Mechanical stirring ensures all feed particles are evenly exposed to the low-pressure environment, preventing the feed from becoming damp and caking, thus ensuring the high efficiency of the drying process.

[0034] Example 2

[0035] Meanwhile, to further enhance the moisture-proof and preservation effect and meet the needs of long-term storage, this embodiment utilizes a gas supply device to supply inert gas or dry gas, etc., through a first gas port 101 at the top of the tank 1 to several gas channels 10 vertically arranged along the inner wall of the tank 1. The gas permeates evenly into the entire feed pile inside the tank 1 via the ventilation panel 3. During this process, the air content decreases in conjunction with the action of the suction device, and the inert gas content is evenly distributed within the tank 1. Optionally, after a period of ventilation, the internal vacuum can be created and maintained by suction, thereby achieving a better feed storage effect.

[0036] Example 3

[0037] The difference from Embodiment 1 is that, preferably, a plurality of second air ports 102 corresponding one-to-one with air passages 10 are fixedly connected to the side of the tank body 1, and the second air ports 102 are connected to an air supply device through pipes. The second air ports 102 installed on the side allow for a more even distribution of gas within the tank body 1 during the air supply process, thereby improving air supply efficiency.

[0038] Preferably, a support frame 01 is fixedly connected to the bottom of the tank body 1. The support frame 01 is used to elevate the tank body 1, thereby providing sufficient operating space below the discharge port 12. The support frame 01 ensures that when the solenoid valve 121 of the discharge port 12 is opened for unloading, a material cart, material bag, or other receiving container can be easily placed below it. Preferably, the support frame 01 can also be used to install a conveyor belt device to transport the unloaded feed to several aquaculture ponds within the aquaculture site.

[0039] Preferably, a safety valve 14 is fixedly connected to the top of the tank 1. Under normal system operation, such as during vacuuming or filling with protective gas, the safety valve 14 remains closed to ensure the airtightness of the tank 1. However, if a control system malfunction or unexpected event causes the internal pressure of the tank 1 to abnormally rise or fall beyond a preset safety limit, the safety valve 14 will automatically open to promptly release pressure or draw in external gas, thereby effectively preventing permanent damage to the structure of the tank 1 and its connecting pipes that may be caused by pressure.

[0040] Preferably, an observation port 15 is fixedly connected to the top of the tank body 1. The observation port 15 is made of transparent, high-strength material and is airtightly connected to the tank body 1 through a reliable sealing structure. While ensuring the overall airtightness of the tank body 1, the observation port 15 provides the user with a direct visual window.

[0041] Preferably, the outer side of the air passage 10 is provided with a transition surface 4 that smoothly transitions with the inner wall of the tank 1. The transition surface 4 ensures that the stirring blades 23 do not create a stirring dead zone in the material chamber 100 when rotating.

[0042] Preferably, the partition constituting the air duct 10 is provided with a sliding groove 41, and the vent panel 3 is slidably connected inside the sliding groove 41. The partition is provided with several fixing holes 42 corresponding to the sliding groove 41. The vent panel 3 can be fixedly installed on the sliding groove 41 by the cooperation of bolts with the fixing holes 42. Specifically, the tank 1 is a split type. During installation, the lower half of the tank 1 is installed first inside the factory, then the vent panel 3 is installed on the lower half of the tank 1, and finally the upper half of the tank 1 is installed to make it a whole. The installation method of the vent panel 3 through the sliding groove 41 makes the installation process more convenient.

[0043] Preferably, the ventilation panel 3 includes a support net 32 ​​and a baffle net 31, which are respectively located on one side 10 near the air passage and on the other side near the feed chamber 100. The support net 32 ​​provides rigid support, and the baffle net 31 is used to block feed particles. Together, they prevent feed from leaking into the air passage 10.

[0044] In summary, during actual use, the operator first loads the feed into the material chamber 100 of the tank 1 through the loading port 11 and seals it. Then, the vacuum device is activated to evacuate the material chamber 100 through the air extraction port 16. At the same time, the motor 21 drives the stirring blades 23 on the rotating shaft 22 to rotate slowly, turning the feed to assist in drying and prevent clumping. If long-term storage is required, the gas supply device can be activated to introduce inert gas or other protective gases into the air passage 10 through the first air port 101 or the second air port 102. The gas is evenly diffused throughout the feed pile through the ventilation panel 3 to replace the humid air or establish a protective atmosphere. During the entire storage period, the internal condition can be checked at any time through the observation port 15, while the safety valve 14 always provides overpressure protection. Finally, when it is necessary to remove the feed, the internal and external air pressures are made consistent by controlling the system air valve, and the solenoid valve 121 of the discharge port 12 is opened, allowing the feed to be discharged smoothly.

[0045] Therefore, this device fundamentally prevents feed spoilage by removing moisture from the feed chamber 100. Secondly, the stirring blades 23 driven by the motor 21 effectively prevent feed caking, ensuring the looseness and uniform drying of the material. The inert gas introduced through the air duct 10 and the ventilation panel 3 further creates a low-oxygen preservation environment, complementing the vacuum drying process. The entire device significantly improves the stability and reliability of feed storage, greatly reduces waste, and lowers labor management costs due to its high degree of automation.

[0046] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
