Description

Technical Field

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

[0002] Aquatic feed is specifically designed for aquatic animal farming. Based on the species being fed, aquatic feed can be categorized into fish feed, shrimp feed, and crab feed. Based on feed characteristics, it can be classified into compound feed, concentrated feed, and premixed feed. The raw materials for aquatic feed production mainly consist of fishmeal, grains, and oils, with fishmeal and grains often accounting for more than 50% of the feed cost. During the processing of aquatic feed, drying equipment is required to extend its shelf life.

[0003] However, existing feed production drying equipment has the following problems during use:

[0004] Existing drying tanks are typically placed horizontally. During feeding and heating, blockages easily occur, preventing materials from entering the drying tank evenly and smoothly, resulting in low feeding efficiency and impacting overall production progress. Furthermore, during heating, horizontally placed drying tanks make it difficult for hot air to distribute evenly within the tank, leading to uneven heating of different parts of the feed. This can result in some areas being over-dried while others are under-dried, significantly affecting the drying quality of the feed, reducing product quality, and also wasting energy.

[0005] This invention can reduce the rotational resistance of the drying tank, reduce energy consumption, stabilize the rotation to ensure uniform heating of the feed, and break up the feed during feeding and discharging to facilitate contact with hot air, effectively remove moisture, and improve drying efficiency and quality. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a rapid drying device for aquatic feed production.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid drying device for aquatic feed production, comprising: a drying box, a rotating drying tank inside the drying box, a feed hopper fixedly installed on the upper right side of the drying box, a discharge hopper fixedly installed at the bottom of the drying box, a hot air blower fixedly installed on the left side inside the drying tank, a rotating cavity opened inside the drying box, a drying tank rotatably installed inside the rotating cavity, a second motor fixedly installed on the left end inside the drying tank, a screw rod fixedly installed at the output end of the second motor, the drying tank being inclined at 3-10 degrees, the feed hopper and the discharge hopper having the same structure, and the hot air blower being positioned above the second motor.

[0008] A further preferred embodiment: the inner wall of the drying chamber is provided with several roller grooves, several auxiliary rollers are rotatably connected in the roller grooves, and the auxiliary rollers are movably connected to the outer surface of the drying chamber.

[0009] A further preferred embodiment: a motor is fixedly installed at the right end inside the drying chamber, and the output end of the motor is fixedly connected to the drying tank. A rotating rod is rotatably installed at the left end inside the drying chamber, and the other end of the rotating rod is fixedly connected to the drying tank.

[0010] A further preferred embodiment: a motor is fixedly installed on the outer end face of the feed hopper, a main gear is rotatably installed on the outer end face of the feed hopper, a secondary gear is rotatably installed on one side of the main gear, the main gear and the secondary gear mesh with each other, and the output end of the motor is fixedly connected to the main gear.

[0011] A further preferred embodiment: a crushing roller is rotatably installed on both the front and rear sides of the inside of the feed hopper, and one end of the crushing roller is fixedly connected to the main gear and the auxiliary gear respectively.

[0012] A further preferred embodiment: a duct is fixedly installed on the right end of the hot air blower, the outlet of the duct is connected to the left end of the drying tank, and a filter screen is fixedly installed thereon.

[0013] Beneficial effects:

[0014] 1. By setting up roller grooves and auxiliary rollers, when the drying tank is rotated by the motor, the auxiliary rollers contact the outer surface of the drying tank and rotate in the roller grooves. Since rolling friction is much less than sliding friction, the frictional resistance between the drying tank and the inner wall of the drying chamber is greatly reduced, reducing energy consumption and avoiding excessive wear of the equipment. Multiple auxiliary rollers are evenly distributed between the inner wall of the drying chamber and the outer surface of the drying tank, providing multi-point support for the drying tank. During its rotation, it effectively prevents shaking or deviation, ensures that the feed is evenly distributed in the tank, ensures the stable operation of the drying process, improves drying efficiency and uniformity, and ultimately improves the performance and service life of the entire drying device.

[0015] 2. Equipped with a motor, main gear, auxiliary gear, and crushing rollers, when the motor starts, its output drives the main gear to rotate. The main and auxiliary gears mesh with each other, causing the auxiliary gear to rotate in the opposite direction, which in turn drives the crushing rollers on the front and rear sides of the feed hopper to rotate synchronously at high speed. This structure can effectively crush and disperse the aquatic feed fed into the feed hopper, preventing feed from clumping. After the dispersed feed enters the drying tank, the hot air can fully contact the feed, improving drying efficiency and avoiding uneven drying caused by the difficulty of evaporating internal moisture due to material clumping. This ensures that the feed is heated evenly during the drying process, improving the drying effect and product quality, and effectively guaranteeing the efficient operation of the drying process.

[0016] 3. In summary, this rapid drying device for aquatic feed production comprises a rotating chamber, roller trough, auxiliary roller, motor three, main gear, auxiliary gear, crushing roller, hot air blower, and filter screen. The rotating chamber, in conjunction with motor one, provides conditions for stable rotation of the drying tank, ensuring that the feed is fully tumbled during the drying process. The roller trough and auxiliary roller work together to reduce frictional resistance during the rotation of the drying tank, lowering energy consumption, and enhancing the stability of the drying tank's rotation, ensuring uniform heating of the feed. Motor three drives the main and auxiliary gears, which in turn drive the crushing roller to crush and disperse the feed in the feed hopper, preventing clumping and facilitating full contact between hot air and feed, thus improving drying efficiency. The hot air blower generates hot air, which enters the drying tank after being filtered through the filter screen to remove impurities, ensuring a clean drying process and effectively removing moisture from the feed.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-4In this embodiment of the present invention, a rapid drying device for aquatic feed production includes: a drying box 1, a rotating drying tank 2 inside the drying box 1, a feed hopper 3 fixedly installed on the upper right side of the drying box 1, a discharge hopper 4 fixedly installed at the bottom of the drying box 1, a hot air blower 5 fixedly installed on the left side inside the drying tank 2, a rotating cavity 101 opened inside the drying box 1, the drying tank 2 rotatably installed inside the rotating cavity 101, a second motor 201 fixedly installed on the left end inside the drying tank 2, a screw rod 202 fixedly installed at the output end of the second motor 201, and the drying tank 2 is inclined at 3-10 degrees. The feed hopper 3 and the discharge hopper 4 are structurally identical. The hot air blower 5 is positioned above motor 201. Motor 104 is fixedly installed on the right side inside the drying chamber 1, with its output end fixedly connected to the drying tank 2. A rotating rod 105 is rotatably installed on the left side inside the drying chamber 1, with its other end fixedly connected to the drying tank 2. An air duct 501 is fixedly installed on the right side of the hot air blower 5, with its output port connected to the left side of the drying tank 2 and a filter 502 fixedly installed thereon. When motors 104 and 201 are turned on, motor 104 drives the drying tank 2 to rotate within the rotating chamber 101; motor 201 drives the screw rod 202 to rotate, thus removing the drying tank from the drying chamber. The dried aquatic feed is fed into the drying tank 2 through the feed hopper 3. Because the drying tank 2 is tilted at 3-10 degrees and the screw 202 rotates, the feed first slides to the left under gravity, and then moves from the left end to the right end of the drying tank 2 under the push of the screw 202. The hot air blower 5 is activated, and the hot air generated by the blower 5 enters the drying tank 2 through the air duct 501. The filter screen 502 filters out any impurities that may be present in the hot air, preventing them from mixing into the feed. The hot air makes full contact with the aquatic feed moving inside the drying tank 2, transferring heat and causing the moisture in the feed to evaporate rapidly. The drying tank 2 is then heated by electricity. Driven by motor 104, the feed rotates continuously, causing it to tumble inside the tank, increasing the contact area between the feed and the hot air, and improving drying efficiency and uniformity. As the drying tank 2 rotates and the feed moves, the feed undergoes a thorough drying process inside the drying tank 2. When it is time to discharge, the rotation of the screw 202 inside the drying tank 2 is stopped. The dried aquatic feed moves to the bottom left end of the drying tank 2 under the tilting action of the drying tank 2 and is discharged from the drying device through the discharge hopper 4. After all the feed is discharged, the hot air blower 5 is turned off to stop the supply of hot air, and then motor 104 is turned off to stop the drying tank 2 from rotating.

[0024] In this embodiment of the invention, the inner wall of the drying chamber 1 is provided with several roller grooves 102, and several auxiliary rollers 103 are rotatably connected within the roller grooves 102. The auxiliary rollers 103 are movably connected to the outer surface of the drying tank 2. When the motor 104 starts and drives the drying tank 2 to rotate within the rotating cavity 101, the auxiliary rollers 103 begin to function. Since the auxiliary rollers 103 are rotatably connected within the roller grooves 102 on the inner wall of the drying chamber 1 and are movably connected to the outer surface of the drying tank 2, friction is generated between the outer surface of the drying tank 2 and the auxiliary rollers 103 when the drying tank 2 rotates. Under the action of this friction, the auxiliary rollers 103 begin to rotate within the roller grooves 102. As the drying tank 2 continues to rotate, the auxiliary rollers 103 continuously contact and roll with the outer surface of the drying tank 2, assisting the rotation of the drying tank 2 throughout the process. The presence of the auxiliary rollers 103 greatly reduces the friction between the drying tank 2 and the inner wall of the drying chamber 1 during rotation. Without the auxiliary rollers 103, the drying tank 2 would rotate directly in contact with the inner wall of the drying chamber 1, generating significant frictional resistance. This would not only consume more electrical energy to drive the motor 104 but also potentially lead to increased wear on both the drying tank 2 and the inner wall of the drying chamber 1. The rolling friction of the auxiliary rollers 103 is far less than the sliding friction of direct contact, allowing the drying tank 2 to rotate more smoothly, reducing energy consumption and improving energy efficiency. Furthermore, the multiple auxiliary rollers 103 are evenly distributed between the inner wall of the drying chamber 1 and the outer surface of the drying tank 2, providing multi-point support for the drying tank 2. During the rotation of the drying tank 2, these auxiliary rollers 103 can effectively prevent the drying tank 2 from shaking or shifting, ensuring that the drying tank 2 always maintains a stable rotation state and avoiding uneven distribution of feed inside the tank due to shaking, which would affect the drying effect.

[0025] In this embodiment of the invention, a motor 301 is fixedly installed on the outer end face of the feed hopper 3, a main gear 302 is rotatably installed on the outer end face of the feed hopper 3, and a secondary gear 303 is rotatably installed on one side of the main gear 302. The main gear 302 and the secondary gear 303 mesh with each other. The output end of the motor 301 is fixedly connected to the main gear 302. A crushing roller 304 is rotatably installed on both the front and rear sides inside the feed hopper 3. One end of the crushing roller 304 is fixedly connected to the main gear 302 and the secondary gear 303, respectively. When the equipment is ready to feed material, the motor 301 is started, and the output end of the motor 301 drives the main gear 302 to start rotating. 302 meshes with the auxiliary gear 303, which rotates in the opposite direction to the rotation of the main gear 302. The main gear 302 and the auxiliary gear 303 are fixedly connected to the front and rear crushing rollers 304 inside the feed hopper 3, respectively, thereby driving the crushing rollers 304 to rotate synchronously. At this time, the aquatic feed to be dried is put into the feed hopper 3. Under the high-speed rotation of the crushing rollers 304, the feed is crushed and dispersed, and then enters the drying tank 2 for the drying process. This helps the hot air to fully contact the feed during the drying process, improves the drying efficiency, and avoids uneven drying due to the difficulty of evaporating internal moisture caused by material clumping.

[0026] Working principle: First, motor 301 is turned on, and its output drives the main gear 302 to rotate. Since the main gear 302 meshes with the auxiliary gear 303, the auxiliary gear 303 rotates in the opposite direction. The main and auxiliary gears drive the crushing rollers 304 on the front and rear sides of the feed hopper 3 to rotate synchronously at high speed. The aquatic feed to be dried is put into the feed hopper 3. Under the action of the high-speed rotating crushing rollers 304, the feed is crushed and dispersed to avoid clumping, which is conducive to subsequent drying. The dispersed feed enters the drying tank 2 by gravity and the thrust generated by the rotation of the crushing rollers 304. Then, motors 104 and 201 are turned on. Motor 104 drives the drying tank 2 to rotate in the rotating chamber 101. Internal rotation; motor 201 drives screw 202 to rotate. At this time, auxiliary roller 103 generates friction due to contact with the outer surface of drying tank 2 and rotates in roller groove 102. The auxiliary drying tank 2 rotates smoothly, reducing frictional resistance and equipment wear. Since the drying tank 2 is set at an inclination of 3-10 degrees and screw 202 rotates, the feed first slides to the left under the action of gravity, and then moves from the left end to the right end of drying tank 2 under the push of screw 202. The hot air generated by hot air blower 5 enters drying tank 2 through air duct 501. After the filter screen 502 filters impurities, the hot air enters from the left side of drying tank 2 and forms a countercurrent contact with the aquatic feed moving from the right side to the left. This counter-current method maintains a large temperature and humidity difference between the hot air and the feed, which is beneficial for heat transfer and moisture evaporation, allowing the moisture in the feed to evaporate rapidly. At the same time, the drying tank 2 rotates continuously, causing the feed to tumble and increasing the contact area with the hot air, thus improving drying efficiency and uniformity. When the feed is dried and needs to be discharged, motor 201 is stopped first, causing the screw 202 to stop rotating. The dried aquatic feed moves to the bottom left end of the drying tank 2 under the tilting action of the drying tank 2 and is discharged from the drying device through the discharge hopper 4. After all the feed is discharged, the hot air blower 5 is turned off first to stop the supply of hot air; then motor 104 is turned off to stop the rotation of the drying tank 2; finally, motor 301 is turned off.
