Description

Technical Field

[0001] This utility model relates to the field of feed additive processing technology, specifically a high-efficiency drying and screening device. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They are used in very small quantities in feed but have significant effects. Feed additives are essential raw materials used in the modern feed industry.

[0003] Existing drying and screening equipment often encounters screening obstacles when processing feed additives due to the tendency of the additives to clump together. Clumped additives cannot pass through the sieve holes, which not only reduces screening efficiency but also requires manual cleaning of the clumps, increasing labor costs. At the same time, the heating path of traditional equipment is singular, and the feed additives have a short residence time in the equipment, resulting in insufficient contact with the heat source and easy occurrence of localized under-drying, which affects the use effect of the additives.

[0004] Based on this, a highly efficient drying and screening device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] 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 and embodiments.

[0024] In one embodiment, such as Figures 1-7As shown, a high-efficiency drying and screening device includes a drying chamber 100, in which a rotating tube 101 is rotatably connected. Multiple stirring tubes 102 are fixedly connected to one end of the rotating tube 101 within the drying chamber 100. Air jets 103 are provided on the stirring tubes 102. A screening mechanism is provided within the drying chamber 100. A vibrating component is provided on the rotating tube 101 to drive the screening mechanism to vibrate up and down. Multiple partitions 104 are fixedly connected to the lower end of the screening mechanism within the drying chamber 100. Drop holes 105 are provided on the partitions 104, with the drop holes 105 on each pair of adjacent partitions 104 located on opposite sides of the rotating tube 101. The upper ends of the multiple partitions 104 are provided with pushing components. The rotating tube 101 is connected to the transmission module and the blowing unit at one end outside the drying box 100. Feed additives are added into the drying box 100, and the screening mechanism screens the feed additives. At the same time, the transmission module drives the rotating tube 101 and the stirring tube 102 to stir and disperse the feed additives, ensuring screening efficiency. The shaking component drives the screening mechanism to shake up and down, which improves the screening efficiency. The screened feed additives fall onto the uppermost partition 104. The pushing component pushes the feed additives from the drop hole 105 to the next partition 104, and so on, increasing the drying time of the feed additives and improving the drying effect.

[0025] In this embodiment, as Figure 3 and Figure 4 As shown, the screening mechanism includes a screening frame 201, which is slidably connected inside the drying chamber 100. A screening plate 202 is provided in the screening frame 201. One end of a spring 203 is fixedly connected to the lower end of the screening frame 201, and the other end of the spring 203 is fixedly connected to a fixing block 204. The fixing block 204 is fixedly connected to the inner wall of the drying chamber 100. When the shaking component drives the screening frame 201 to move, the screening frame 201 slides up and down along the inner wall of the drying chamber 100. The feed additives are placed on the screening plate 202. Under the shaking action of the screening frame 201, the feed additives that meet the aperture requirements of the screening plate 202 fall through the sieve holes, while the additives that are agglomerated or have a larger particle size are left on the screening plate 202.

[0026] In one embodiment, such as Figure 4 and Figure 7As shown, the shaking component includes a first fixed ring 301 and a second fixed ring 302. The first fixed ring 301 is fixedly connected to the outer end of the rotating tube 101, and the second fixed ring 302 is fixedly connected to the lower end of the screening plate 202. Two symmetrically arranged protrusions 303 are fixedly connected to the first fixed ring 301, and the lower end of the second fixed ring 302 is provided with a second protrusion 304 corresponding to the first protrusion 303. When the rotating tube 101 rotates, the first fixed ring 301 rotates synchronously with the rotating tube 101, and the protrusions 303 on the first fixed ring 301 also move accordingly. In the circular motion, when protrusion 1 303 rotates to protrusion 2 304, protrusion 1 303 will exert an upward thrust on protrusion 2 304, which in turn drives the fixed ring 2 302, screening plate 202 and screening frame 201 to move upward. As the rotating tube 101 continues to rotate, protrusion 1 303 and protrusion 2 304 gradually separate. At this time, under the action of the screening frame 201's own weight and spring 203, the screening frame 201 moves downward, and the process of contact and separation is repeated continuously, thereby driving the screening frame 201 to achieve continuous up and down shaking, effectively improving screening efficiency.

[0027] In one embodiment, such as Figure 5 As shown, the feeding component includes two push plates 400, which are fixedly connected to the rotating tube 101 at an incline. The lower end of each push plate 400 is in contact with a partition 104. The two inclined push plates 400 rotate synchronously with the rotating tube 101. During rotation, the inclined surface of the push plate 400 pushes the feed additive on the partition 104 toward the drop hole 105 and drops it from the drop hole 105 onto the next partition 104, thus realizing the step-by-step transfer of feed additives between multiple partitions 104. When pushing the feed additives, the feed additives continuously accumulate on the push plate 400. Excess feed additives will fall from the top of the push plate 400, which serves to flip the feed additives.

[0028] In one embodiment, such as Figure 2 As shown, the transmission module includes a first gear 501, which is fixedly connected to the outer end of the rotating tube 101. The first gear 501 meshes with a second gear 502, which is fixedly connected to the output shaft of a motor 503. The motor 503 is fixedly connected to the upper end of the drying chamber 100. The motor 503 drives the second gear 502 to rotate, which in turn drives the first gear 501 to rotate. The first gear 501 then drives the rotating tube 101 to rotate, thereby performing stirring.

[0029] In one embodiment, such as Figure 1 and Figure 3As shown, the blowing unit includes a connecting pipe 601, which is rotatably connected to one end of the rotating pipe 101 located outside the drying chamber 100. The connecting pipe 601 is fixedly connected to a fixed frame 602, which is fixedly connected to the upper end of the drying chamber 100. The upper end of the fixed frame 602 is fixedly connected to a heating chamber 603. The heating chamber 603 is provided with a heating pipe 604. The air inlet of the heating chamber 603 is connected to the output end of an air pump 605 through a hose, and the air outlet of the heating chamber 603 is connected to the connecting pipe 601 through a hose. The air pump 605 sends air into the heating chamber 603, which is heated by the heating pipe 604 to form hot air. The hot air enters the rotating pipe 101 through the connecting pipe 601 and is then sprayed out through the jet nozzle 103 on the stirring pipe 102 to achieve the drying of feed additives.

[0030] In one embodiment, such as Figure 3 As shown, a stirring tube 102 is provided between each pair of partitions 104. The stirring tube 102 stirs the feed additives during rotation and sprays hot air at the same time to make the drying more uniform.

[0031] In one embodiment, such as Figure 1 As shown, the upper end of the drying box 100 is provided with a feeding port 701, the lower end of the drying box 100 is provided with a discharge port 702, and the lower end of the drying box 100 is provided with a mounting frame 703. Feed additives are added to the drying box 100 through the feeding port 701, and the processed feed additives are discharged from the discharge port 702. The mounting frame 703 is used to fix the drying box 100 to ensure the stability of the equipment operation.

[0032] The above embodiment discloses a high-efficiency drying and screening device. Feed additives are added to the drying chamber 100 through the feeding port 701. The feed additives fall onto the screening plate 202. The rotating tube 101 rotates, driving the stirring tube 102 to rotate and disperse the feed additives. The first fixed ring 301 rotates synchronously with the rotating tube 101, and the first protrusion 303 on the first fixed ring 301 also performs a circular motion. When the first protrusion 303 rotates to the second protrusion 304, the first protrusion 303 exerts an upward pushing force on the second protrusion 304, thereby driving the second fixed ring 302, the screening plate 202, and the screening frame 201 upward. As the rotating tube 101 continues to rotate, the first protrusion 303 and the second protrusion 304 gradually separate. At this time, under the weight of the screening frame 201 itself and the action of the spring 203, the screening frame 201 moves downward, continuously repeating the contact and separation process, thereby driving the screening... The divider 201 continuously vibrates up and down to screen the feed additives. The screened feed additives fall onto the uppermost partition 104. Two inclined push plates 400 rotate synchronously with the rotating tube 101. During rotation, the inclined surfaces of the push plates 400 push the feed additives on the partition 104 towards the drop hole 105 and fall from the drop hole 105 onto the next partition 104, realizing the step-by-step transfer of feed additives between multiple partitions 104. When pushing the feed additives, they continuously accumulate on the push plates 400. Excess feed additives fall from the top of the push plates 400, which serves to turn the feed additives over. The air pump 605 sends air into the heating chamber 603, which is heated by the heating tube 604 to form hot air. The hot air enters the rotating tube 101 through the connecting pipe 601 and is then sprayed out from the jet nozzle 103 on the stirring tube 102 to dry the feed additives.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
