Description

Technical Field

[0001] This utility model relates to the field of feed production technology, and in particular to a drying device for aquatic feed. Background Technology

[0002] The production process of aquatic feed involves multiple complex steps, from raw material selection, formula design, processing technology to finished product packaging. Each step is strictly controlled to ensure that the feed quality meets the needs of aquaculture.

[0003] Drying is a crucial step in the production process of aquatic feed. Feed pellets produced through previous processing steps typically contain high moisture content. Without timely and effective drying, this not only affects the storage stability of the feed, making it prone to the growth of mold, bacteria, and other microorganisms, leading to spoilage, reduced feed quality, and shorter shelf life, but also causes clumping during transportation and storage, affecting subsequent feeding outcomes. Existing technologies include various types of aquatic feed drying devices, such as the one disclosed in patent application number CN201721779753.2. This device, through a specific structural design, aims to effectively dry aquatic feed, meeting the drying requirements in the aquatic feed production process to a certain extent and providing technical support for improving feed quality and production efficiency.

[0004] However, although existing aquatic feed drying equipment has made some progress in drying function, there is still considerable room for improvement in its drying efficiency in practical applications. With the rapid development of aquaculture, the demand for aquatic feed is increasing, which requires drying equipment to complete the drying of larger batches of feed in a shorter time to improve overall production efficiency. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a drying device for aquatic feed, so as to further improve the drying efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drying device for aquatic feed includes a cylindrical shell with an inlet and outlet at the top. A detachable cover is attached to the inlet and outlet. A support assembly is located at the top of the shell, and a fixing ring is detachably connected to the support assembly. A drying drum with multiple mesh openings is rotatably connected to the inner wall of the fixing ring via a ring bearing. An air inlet pipe is evenly distributed around the bottom periphery of the shell, with its outlet located below the drying drum. A hot air assembly is installed inside the air inlet pipe. An exhaust port is located at the top of the shell. A rotation drive assembly for rotating the drying drum is located at the bottom of the shell. A transmission assembly is fixedly mounted on the output shaft of the rotation drive assembly, and the transmission assembly is detachably connected to the bottom of the drying drum.

[0008] Preferably, the supporting component includes a limiting ring fixedly disposed at the top of the housing, the limiting ring being used to support the fixing ring, and the inner diameter of the limiting ring being lower than the outer diameter of the drying drum.

[0009] Preferably, the upper surface of the limiting ring is uniformly provided with limiting rods, and the fixing ring is provided with limiting holes that are adapted to the limiting rods.

[0010] Preferably, the top of the limiting rod is provided as an external thread rod, and the external thread rod is threadedly connected to a limiting knob, the size of which is larger than the size of the limiting hole.

[0011] Preferably, the rotation drive assembly is a reversible motor, the transmission assembly includes a transmission bracket fixedly connected to the motor output shaft, the top of the transmission bracket is uniformly provided with a plurality of snap-fit ​​blocks in a ring, and the bottom of the drying drum is provided with a plurality of snap-fit ​​slots adapted to the snap-fit ​​blocks.

[0012] Preferably, the bottom of the snap-fit ​​groove is provided with a flared guide groove, and the top of the snap-fit ​​block is provided with an arc shape.

[0013] Preferably, the hot air assembly includes an intake fan fixedly installed inside the intake pipe, an electric heating grid is provided on one side of the intake fan, and a filter screen is provided at the air inlet of the intake pipe.

[0014] Preferably, the outer wall of the inlet / outlet is provided with an external thread, and the inner wall of the bottom of the sealing cover is provided with an internal thread that matches the external thread.

[0015] This utility model has the following beneficial effects:

[0016] I. Rotary Drying Tank Design: A rotating drive assembly located at the bottom of the shell drives a transmission assembly, which in turn drives the drying tank to rotate. During the rotation of the drying tank, the aquatic feed inside is constantly turned over, allowing the feed to come into more thorough and even contact with the hot air. This avoids the problem of uneven drying caused by localized feed accumulation, greatly shortens the drying time, and improves drying efficiency, meeting the aquaculture industry's demand for rapid drying of large quantities of feed.

[0017] II. Optimized Layout of Hot Air Components: Air inlets are evenly spaced in a ring around the bottom of the casing, with their outlets located below the drying drum. A hot air component is installed inside each inlet. This layout allows hot air to be evenly blown upwards from the bottom of the drying drum, comprehensively surrounding the feed inside. This enhances the contact between the hot air and the feed, accelerates the evaporation of moisture, and effectively improves drying efficiency.

[0018] III. Connection Method between Support Component and Fixing Ring: The upper surface of the limiting ring of the support component is uniformly equipped with limiting rods in a ring. The fixing ring has limiting holes that match the limiting rods. The top of the limiting rod is an externally threaded rod, which is threadedly connected to a limiting knob. The size of the limiting knob is larger than the size of the limiting hole. This design allows the fixing ring to be easily installed on the limiting ring. Precise positioning is achieved through the cooperation of the limiting rods and limiting holes, and then the limiting knob is used for fixation. Disassembly is simple and quick; just unscrew the limiting knob to remove the fixing ring. This facilitates the installation, replacement, and cleaning of components such as the drying drum.

[0019] IV. Connection Method between Transmission Component and Drying Drum: The transmission bracket of the transmission component has multiple evenly spaced snap-fit ​​blocks arranged in a ring at its top. The bottom of the drying drum has multiple snap-fit ​​grooves that fit the snap-fit ​​blocks, and the bottom of each snap-fit ​​groove has a flared guide groove. The top of each snap-fit ​​block is rounded. This snap-fit ​​structure allows the transmission component and the drying drum to connect and separate quickly and accurately. During installation, the snap-fit ​​blocks smoothly enter the snap-fit ​​grooves under the guidance of the guide grooves, achieving a stable connection. During disassembly, only a certain amount of external force is needed to separate the two, facilitating the maintenance and replacement of the drying drum.

[0020] V. Connection method between inlet / outlet and sealing cover: The outer wall of the inlet / outlet is provided with external threads, and the inner wall of the bottom of the sealing cover is provided with internal threads that match the external threads. Through the threaded connection, the sealing cover can be easily installed on the inlet / outlet to achieve a seal and prevent hot air leakage and the entry of external impurities; when it is necessary to feed or discharge, it can be removed simply by rotating the sealing cover, which is easy to operate.

[0021] VI. Ensuring Hot Air Quality and Safety: The hot air assembly includes an intake fan fixedly installed inside the intake pipe, an electric heating grid on one side of the intake fan, and a filter screen at the air inlet of the intake pipe. The intake fan draws in outside air, which is then filtered by the filter screen to remove dust, impurities, and other contaminants, ensuring the cleanliness of the hot air entering the device and preventing feed contamination. The electric heating grid heats the filtered air, providing a suitable drying temperature. This design ensures both the quality of the hot air and a safe and hygienic environment for drying aquatic feed.

[0022] 7. Achieving Forward and Reverse Rotation of the Drying Drum: The rotation drive component is equipped with a forward and reverse rotating motor. The forward and reverse rotating motor can drive the drying drum to rotate in both directions. Compared with rotation in one direction, forward and reverse rotation can make the feed in the drying drum more thoroughly turned over, further improving the uniformity of contact between the feed and the hot air, thereby improving the drying effect and ensuring that all parts of the feed can reach the ideal drying degree.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] First embodiment

[0030] like Figures 1 to 2 As shown, a drying device for aquatic feed includes a cylindrical shell 1. The top of the shell 1 has an inlet / outlet 101, and a detachable cover 2 is connected to the inlet / outlet 101. A support assembly is provided at the top inside the shell 1, and a fixing ring 301 is detachably connected to the support assembly. A drying drum 303 with multiple mesh holes is rotatably connected to the inner wall of the fixing ring 301 through a ring bearing 302. The diameter of the mesh holes is smaller than the size of the aquatic feed. An air inlet pipe 401 is evenly provided in a ring around the bottom of the shell 1. The air outlet of the air inlet pipe 401 is located below the drying drum 303. A hot air assembly is provided inside the air inlet pipe 401. An exhaust hole 402 is provided at the top of the shell 1. A rotation drive assembly 5 for driving the drying drum 303 to rotate is provided at the bottom inside the shell 1. A transmission assembly is fixedly provided on the output shaft of the rotation drive assembly 5. The transmission assembly is detachably connected to the bottom of the drying drum 303.

[0031] like Figures 1 to 2As shown, open the detachable sealing cover 2 at the inlet / outlet 101 on the top of the housing 1, and pour the aquatic feed to be dried into the drying drum 303 inside the housing 1, which is supported by a fixed ring 301 detachably connected to the support assembly and rotatably connected by a ring bearing 302. After feeding, reinstall the sealing cover 2 to keep the device in a closed state, preventing hot air leakage and the entry of external impurities during the subsequent drying process. The hot air assembly inside the evenly spaced air inlet pipe 401 on the bottom periphery of the housing 1 starts to work. The air intake fan 801 in the hot air assembly operates, drawing in outside air from the air inlet of the air inlet pipe 401. The filter screen 803 installed at the air inlet filters the drawn-in air, removing dust, impurities, etc., to ensure that the air entering the device is clean. The filtered air continues to flow forward and is heated when passing through the electric heating grid 802, forming hot air. Hot air is blown evenly upwards from the air outlet of the air inlet pipe 401. Since the air outlet is located below the drying drum 303, the hot air can surround the drying drum 303 from all directions, providing heat for drying the aquatic feed. The rotation drive component 5, located at the bottom of the housing 1, starts to work, and its output shaft drives the fixedly connected transmission component to rotate. The transmission component is detachably connected to the bottom of the drying drum 303. Under the action of the transmission component, the drying drum 303 starts to rotate within the fixed ring 301 via the ring bearing 302. During the rotation of the drying drum 303, the aquatic feed inside will be constantly turned over, allowing the feed to come into more full and even contact with the hot air, accelerating the evaporation of moisture in the feed. Moreover, the rotation drive component 5 can drive the drying drum 303 to achieve forward and reverse rotation (because it can be set as a forward and reverse reversible motor). Forward and reverse rotation can make the feed turn over more fully, further improving the drying uniformity.

[0032] During the drying process, the water vapor formed by the evaporation of feed moisture, along with some hot air, rises to the top of the shell 1 and is discharged outside the device through the exhaust port 402 at the top of the shell 1. This ensures stable air pressure inside the device, maintains a good drying environment, and allows the drying process to continue efficiently. After the aquatic feed is dried, the sealing cover 2 is opened, and the dried feed is taken out through the inlet / outlet 101. Meanwhile, since the supporting components and fixing ring 301, the transmission components and drying drum 303 are all detachably connected, it is convenient to disassemble, clean, and maintain components such as the drying drum 303 and fixing ring 301 to ensure the performance and hygiene of the device for the next use.

[0033] like Figures 1 to 2As shown, the supporting assembly includes a limiting ring 601 fixedly installed at the top of the housing 1. The limiting ring 601 supports the fixing ring 301. The inner diameter of the limiting ring 601 is lower than the outer diameter of the drying drum 303, which can provide lateral limiting for the drying drum 303 and prevent the drying drum 303 from shifting significantly laterally during rotation. Limiting rods 602 are evenly arranged in a ring on the upper surface of the limiting ring 601. The fixing ring 301 has limiting holes that fit the limiting rods 602. During installation, the limiting holes of the fixing ring 301 are aligned with the limiting rods 602 and inserted, so that the fixing ring 301 is stably placed on the limiting ring 601. Then, the annular bearing 302 on the inner wall of the fixing ring 301 supports the drying drum 303, ensuring the stability of the drying drum 303 during rotation.

[0034] like Figures 1 to 2 As shown, the rotation drive assembly 5 is a reversible motor. The transmission assembly includes a transmission bracket 701 fixedly connected to the motor output shaft. Multiple locking blocks 702 are evenly arranged in a ring on the top of the transmission bracket 701, and multiple locking slots 703 adapted to the locking blocks 702 are provided at the bottom of the drying drum 303. The rotation drive assembly 5 uses a reversible motor. After the motor starts, its output shaft drives the transmission bracket 701, which is fixedly connected to it, to rotate. The multiple locking blocks 702 are evenly arranged in a ring on the top of the transmission bracket 701, and multiple locking slots 703 adapted to the locking blocks 702 are provided at the bottom of the drying drum 303. The locking blocks 702 are embedded in the locking slots 703, connecting the transmission bracket 701 to the drying drum 303, thereby transmitting the motor's rotation to the drying drum 303 and driving the drying drum 303 to rotate. The reversible motor enables the drying drum 303 to rotate in both directions. During the rotation, the aquatic feed inside the drying drum 303 will be constantly turned over, allowing the feed to come into more full and even contact with the hot air, accelerating the evaporation of moisture in the feed, and improving drying efficiency and uniformity.

[0035] like Figures 1 to 2 As shown, the hot air assembly includes an intake fan 801 fixedly installed inside the intake pipe 401. An electric heating grid 802 is installed on one side of the intake fan 801, and a filter screen 803 is installed at the air inlet of the intake pipe 401. The intake fan 801, fixedly installed inside the intake pipe 401, draws in outside air through the air inlet of the intake pipe 401 upon startup. The filter screen 803 at the air inlet filters the intake air, removing dust, particles, and other impurities to ensure clean air entering the device and prevent contamination of the feed. The filtered air continues to flow and is heated as it passes through the electric heating grid 802 on one side of the intake fan 801, forming hot air. The hot air is blown out from the air outlet of the intake pipe 401. Since the air outlet is located below the drying drum 303, the hot air can be evenly blown upwards towards the drying drum 303, providing the heat required for drying the aquatic feed inside the drying drum 303.

[0036] like Figures 1 to 2 As shown, the outer wall of the inlet / outlet 101 is provided with external threads, and the inner wall of the bottom of the sealing cover 2 is provided with internal threads that match the external threads. By rotating the sealing cover 2, it is tightly installed on the inlet / outlet 101 using the threaded connection, forming a closed space inside the device to prevent hot air leakage during the subsequent drying process and to prevent external dust, impurities, etc. from entering and contaminating the feed. Afterwards, the sealing cover 2 is opened, and the aquatic feed to be dried is poured into the drying drum 303 through the inlet / outlet 101, and then the device is resealed.

[0037] Second embodiment

[0038] like Figure 3 As shown, the top of the limiting rod 602 is a threaded rod, and the threaded rod is threadedly connected to a limiting knob 604. The size of the limiting knob 604 is larger than the size of the limiting hole. When installing the fixing ring 301, first align the limiting hole on the fixing ring 301 with the limiting rod 602 on the limiting ring 601 and insert it. The limiting rod 602 plays a positioning role, ensuring that the fixing ring 301 can be accurately placed on the limiting ring 601, thereby achieving initial support and positioning of the drying drum 303 and preventing the drying drum 303 from shifting significantly in the horizontal direction. The top of the limiting rod 602 is a threaded rod, and the limiting knob 604 is threadedly connected to it. The size of the limiting knob 604 is larger than the size of the limiting hole. After the fixing ring 301 is inserted into the limiting rod 602, the limiting knob 604 is screwed onto the threaded rod of the limiting rod 602. As the limiting knob 604 is continuously tightened, it will press tightly against the upper surface of the fixing ring 301. This design increases the connection stability between the fixing ring 301 and the limiting ring 601, preventing the fixing ring 301 from falling off the limiting rod 602 due to vibration or centrifugal force during the rotation of the drying drum 303, thereby ensuring the reliability of the entire support structure and enabling the drying drum 303 to rotate stably within the shell 1.

[0039] like Figure 3As shown, the bottom of the snap-fit ​​groove 703 is provided with a flared guide groove 704, and the top of the snap-fit ​​block 702 is rounded. When connecting the drying drum 303 to the transmission bracket 701, since there may be a certain positional deviation of the drying drum 303 during installation, the flared guide groove 704 can play a guiding role. When the snap-fit ​​block 702 approaches the snap-fit ​​groove 703, the flared opening of the guide groove 704 can gradually guide the snap-fit ​​block 702 to the correct position in the snap-fit ​​groove 703, even if the snap-fit ​​block 702 and the snap-fit ​​groove 703 are not completely aligned, it can still smoothly enter the snap-fit ​​groove 703. The rounded top design of the snap-fit ​​block 702 makes the contact surface of the snap-fit ​​block 702 smoother during contact with the guide groove 704 and entry into the snap-fit ​​groove 703, reducing the friction and collision forces between the two. This not only reduces the difficulty of installation, making it easier for staff to connect the drying drum 303 to the transmission bracket 701, but also reduces the wear of the snap-fit ​​block 702 and snap-fit ​​groove 703 during the connection process, extends the service life of the components, and ensures that the transmission components can work stably for a long time, thereby ensuring that the drying drum 303 can rotate normally and achieve uniform drying of aquatic feed.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
