Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a drum-type fertilizer drying device. Background Technology

[0002] Drying is a crucial process in fertilizer production, directly affecting fertilizer quality, storage stability, and efficacy. Rotary drum dryers are widely used in fertilizer processing due to their simple structure, large capacity, and uniform drying properties. Traditional rotary drum dryers typically employ a single-drum structure, where the material tumbles inside the drum due to its rotation, while a heating device simultaneously dries the material.

[0003] Chinese patent document CN 215295670 U discloses a drum-type fertilizer drying device, which achieves drum rotation by setting up a feed box and a discharge box, and setting bearings at both ends of the drum, resulting in a relatively compact structure. However, in this prior art, fertilizer is dried in a relatively sealed drum, which easily leaves fertilizer residue inside, making it difficult to thoroughly clean the inside. Long-term use can easily lead to material accumulation, cross-contamination, and even affect drying efficiency and product quality.

[0004] Therefore, a drum-type fertilizer drying device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a drum-type fertilizer drying device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A drum-type fertilizer drying device includes a base, above which a first drying cylinder and a second drying cylinder are arranged, abutting against each other. A docking assembly is provided between the first and second drying cylinders. Support rings are rotatably connected to the surfaces of both the first and second drying cylinders. The left support ring is fixedly connected to the top surface of the base, and the right support ring is slidably connected to the top surface of the base. A drive mechanism for controlling the rotation of the first drying cylinder is installed on the left side of the top surface of the base. A feeding hopper is fixedly inserted into the left side of the first drying cylinder, and a sealing cover is provided on the top of the feeding hopper. Electric heating rods are fixedly connected to the inner walls of both the first and second drying cylinders. A sliding control assembly for controlling the lateral movement of the second drying cylinder is provided inside the base. A fixed box is fixedly connected to the center of the top surface of the base, and a receiving box is slidably connected to the inner wall of the fixed box.

[0007] Furthermore, the driving mechanism includes a fixed base, which is fixedly connected to the top surface of the base. A first motor is fixedly mounted on the surface of the fixed base, and a rotating shaft is fixedly connected to the output end of the first motor. A drive gear is fixedly sleeved on the surface of the rotating shaft, and a gear ring is fixedly sleeved on the surface of the first drying cylinder, and the gear ring meshes with the drive gear.

[0008] Furthermore, the sliding control component includes a second motor, which is fixedly installed on the inner wall of the base. A threaded rod is fixedly connected to the output end of the second motor. A support frame is threadedly connected to the surface of the threaded rod, and the top end of the support frame is fixedly connected to the bottom of the support ring on the right side. A sliding column is fixedly connected to the inner wall of the base, and the sliding column is slidably connected to the support frame. A sliding groove is opened through the top surface of the base, and the inner wall of the sliding groove is slidably connected to the sliding column.

[0009] Furthermore, the docking assembly includes a plug, which is fixedly connected to the right end of the first drying cylinder. The left side of the second drying cylinder has an alignment hole, and the inner wall of the alignment hole is movably inserted into the plug.

[0010] Furthermore, an exhaust valve is fixedly installed on the right side of the second drying cylinder.

[0011] Furthermore, the inner diameter of the end of the first drying cylinder and the second drying cylinder that is closer to each other is larger than the inner diameter of the end of the first drying cylinder and the second drying cylinder that is farther from each other.

[0012] Furthermore, rubber pads are fixedly connected to the ends of the first and second drying cylinders that are close to each other.

[0013] Furthermore, both the first and second drying cylinders contain multiple electric heating rods, which are arranged in a ring array.

[0014] The beneficial effects of this utility model are as follows: By opening the sealing cover, fertilizer can be fed from the feeding hopper into the first and second drying cylinders. Then, the sealing cover is closed, and the fertilizer is heated and dried by an electric heating rod. The first drying cylinder rotates via a drive mechanism, and under the action of the docking assembly, the second drying cylinder rotates synchronously, causing the fertilizer inside both cylinders to tumble, thus achieving uniform and comprehensive drying. After drying, the second drying cylinder can be moved to the right via a sliding control assembly, separating the first and second drying cylinders. Both cylinders are now exposed, allowing the fertilizer to fall into the receiving box, completing the unloading process. This invention facilitates rapid fertilizer drying, fully exposes the internal components for easy cleaning, and prevents fertilizer accumulation and cross-contamination. Attached Figure Description

[0021] like Figures 1 to 4 As shown, a drum-type fertilizer drying device includes a base 1. A first drying cylinder 2 and a second drying cylinder 3 are arranged above the base 1, and the first drying cylinder 2 and the second drying cylinder 3 abut against each other. A docking assembly is provided between the first drying cylinder 2 and the second drying cylinder 3. The docking assembly includes an insert block 9, which is fixedly connected to the right end of the first drying cylinder 2. An alignment hole 10 is opened on the left side of the second drying cylinder 3, and the inner wall of the alignment hole 10 is movably inserted into the insert block 9. It should be noted that when the ends of the first drying cylinder 2 and the second drying cylinder 3 abut against each other, the insert block 9 will be inserted into the inner wall of the alignment hole 10. When the drive mechanism 5 controls the first drying cylinder 2 to rotate, it can drive the insert block 9, the alignment hole 10 and the second drying cylinder 3 to rotate, so that the first drying cylinder 2 and the second drying cylinder 3 can rotate synchronously.

[0022] Both the first drying cylinder 2 and the second drying cylinder 3 are rotatably connected to support rings 4. The left support ring 4 is fixedly connected to the top surface of the base 1, and the right support ring 4 is slidably connected to the top surface of the base 1. A drive mechanism 5 for controlling the rotation of the first drying cylinder 2 is installed on the left side of the top surface of the base 1. The drive mechanism 5 includes a fixed base 501, which is fixedly connected to the top surface of the base 1. A first motor 502 is fixedly installed on the surface of the fixed base 501. A rotating shaft 503 is fixedly connected to the output end of the first motor 502. A drive gear 504 is fixedly sleeved on the surface of the rotating shaft 503. A gear ring 505 is fixedly sleeved on the surface of the first drying cylinder 2, and the gear ring 505 meshes with the drive gear 504. It should be noted that by driving the rotating shaft 503 and the drive gear 504 to rotate through the first motor 502, the drive gear 504 will drive the gear ring 505 meshing with it to rotate, thereby controlling the rotation of the first drying cylinder 2.

[0023] A feeding hopper 7 is fixedly inserted into the left side of the first drying cylinder 2, and a sealing cover 8 is provided on the top of the feeding hopper 7. Electric heating rods 11 are fixedly connected to the inner walls of the first drying cylinder 2 and the second drying cylinder 3. A sliding control component 6 for controlling the lateral movement of the second drying cylinder 3 is provided inside the base 1. The sliding control component 6 includes a second motor 601, and the second motor 601 is fixedly installed on the inner wall of the base 1. A threaded rod 602 is fixedly connected to the output end of the second motor 601. A support frame 603 is threadedly connected to the surface of the threaded rod 602, and the top of the support frame 603 is fixedly connected to the bottom of the right support ring 4. A sliding column 604 is fixedly connected to the inner wall of the base 1, and the sliding column 604 is slidably connected to the support frame 603. A sliding groove 605 is opened through the top surface of the base 1, and the inner wall of the sliding groove 605 is slidably connected to the sliding column 604. More specifically, the second motor 601 drives the threaded rod 602 to rotate, and under the action of the thread, the support frame 603 can slide along the surface of the sliding column 604, thereby pushing the second drying cylinder 3 to move laterally.

[0024] An exhaust valve 12 is fixedly installed on the right side of the second drying cylinder 3. More specifically, by setting the exhaust valve 12, the steam generated by heating can be discharged from the inside of the first drying cylinder 2 and the second drying cylinder 3.

[0025] A fixing box 13 is fixedly connected to the center of the top surface of the base 1, and a receiving box 14 is slidably connected to the inner wall of the fixing box 13. The inner diameter of the end of the first drying cylinder 2 and the second drying cylinder 3 that is close to each other is larger than the inner diameter of the end of the first drying cylinder 2 and the second drying cylinder 3 that is far from each other. It should be noted that, since the inner walls of the first drying cylinder 2 and the second drying cylinder 3 are inclined, when the first drying cylinder 2 and the second drying cylinder 3 are separated, the dried fertilizer can slide into the receiving box 14 under the action of gravity, making the discharge more convenient.

[0026] Rubber gaskets are fixedly connected to the close ends of the first drying cylinder 2 and the second drying cylinder 3. More specifically, by placing rubber gaskets on the contact surfaces of the first drying cylinder 2 and the second drying cylinder 3, the contact surfaces can be sealed to prevent fertilizer leakage during the drying process.

[0027] The first drying cylinder 2 and the second drying cylinder 3 each contain multiple electric heating rods 11, which are arranged in a ring array. It should be noted that by setting two sets of ring array-shaped electric heating rods 11 inside the first drying cylinder 2 and the second drying cylinder 3, multiple locations in the fertilizer pile can be heated simultaneously, thereby improving drying efficiency.

[0028] In summary: By opening the sealing cover 8, fertilizer can be fed from the feeding hopper 7 into the first drying cylinder 2 and the second drying cylinder 3. Then, the sealing cover 8 is closed, and the fertilizer is heated and dried by the electric heating rod 11. The drive mechanism 5 controls the rotation of the first drying cylinder 2, and under the action of the docking component, it drives the second drying cylinder 3 to rotate synchronously, causing the fertilizer inside the first drying cylinder 2 and the second drying cylinder 3 to tumble, thereby achieving uniform and comprehensive drying. After drying, the sliding control component 6 can drive the second drying cylinder 3 to move to the right, so that the first drying cylinder 2 and the second drying cylinder 3 are separated from each other. The inside of the first drying cylinder 2 and the second drying cylinder 3 are exposed, and the fertilizer can fall into the receiving box 14, thus completing the feeding. In use, this utility model achieves the effect of facilitating rapid drying of fertilizer, fully exposing the inside of the device, thereby facilitating internal cleaning and avoiding fertilizer accumulation and cross-contamination.
