[0001] This utility model relates to the field of chlorine-based compound fertilizer processing technology, and in particular to a drying device for chlorine-based compound fertilizer processing. Background Technology

[0002] In the production and processing of chlorine-based compound fertilizers, drying is a crucial step in ensuring product quality and preventing caking and deterioration. Currently, the most commonly used drying equipment for chlorine-based compound fertilizers in the industry is the drum dryer or the fixed tank dryer. However, these types of equipment have many technical drawbacks in practical applications: the internal stirring structure of the fixed tank dryer is simple, and the material is prone to accumulate and stick on the inner wall of the tank, which not only leads to uneven drying but also requires regular manual cleaning, increasing operating costs and labor intensity.

[0003] Therefore, developing a drying device for chlorine-based compound fertilizer processing with all-round vibration cleaning is the key to solving the current pain points in the industry. Utility Model Content

[0018] Example 1, such as Figure 1-4 As shown, the drying device for processing chlorine-based compound fertilizer has a vertically arranged drying tank 1 as its core load-bearing structure. The drying tank 1 is made of metal to ensure structural strength and high temperature resistance. A control panel 23 for starting and stopping the equipment and adjusting parameters is fixed to one side of its outer surface by bolts. The control panel 23 is electrically connected to the various electrical components inside the device through wires to realize signal transmission and control. A ladder 24 for personnel to climb and maintain is fixed to the other side of the outer surface of the drying tank 1 by welding. The ladder 24 has uniform step spacing and the surface is treated with anti-slip treatment. At least three supporting feet 25 are evenly distributed around the bottom of the drying tank 1. The supporting feet 25 are welded and fixed to the bottom of the drying tank 1, and anti-slip pads can be added to the bottom to enhance the stability of the device. A discharge port for discharging dried material is opened at the center of the bottom of the drying tank 1. A valve can be installed at the discharge port to control the material discharge speed. A feeding funnel 26 for feeding is connected through a flange structure on one side of the top of the drying tank 1. The feeding funnel 26 has a conical structure with the larger opening facing up and the smaller opening facing down and is connected to the inside of the drying tank 1 to facilitate the smooth entry of material into the tank.

[0019] The drying tank 1 is equipped with a vibrating assembly on its side to shake off materials adhering to the tank wall. A drive motor 14 is bolted to the center of the top of the drying tank 1. The drive motor 14 is an adjustable speed motor to adapt to different drying requirements. The output shaft of the drive motor 14 extends vertically downward through the top wall of the drying tank 1. The penetration point is sealed with a sealed bearing to prevent leakage of hot air inside the tank. The end of the output shaft extending into the tank is coaxially fixed to a hollow transmission rod 15 via a coupling. An elastic coupling is used to buffer vibrations during transmission. The hollow transmission rod 15 is made of a hollow metal tube. Its bottom is rotated and engaged with a venting connection pipe 151 fixed to the center of the bottom of the drying tank 1 via a rotary bearing 152. The inner ring of the rotary bearing 152 is fixed to the outer circumference of the venting connection pipe 151, and the outer ring is fixed to the inner circumference of the hollow transmission rod 15. The hollow transmission rod 15 and the venting connection pipe 151 are kept in communication to ensure smooth gas flow.

[0020] A blower 16 is fixedly installed on the top of the drying tank 1 and on one side of the drive motor 14 via a bracket. The blower 16 can be equipped with a heating component to generate hot air. The output end of the blower 16 is connected to the ventilation connection pipe 151 via a gas supply pipe 161. The gas supply pipe 161 is made of high-temperature resistant hose or metal pipe. Its end away from the blower 16 passes through the side wall of the drying tank 1 and extends into the tank. It is fixed to the outer peripheral wall of the ventilation connection pipe 151 by welding and maintains a continuous connection. The connection is sealed to prevent gas leakage.

[0021] Multiple mounting positions are spaced axially along the outer periphery of the hollow drive rod 15. At least two horizontally positioned stirring rods 17 are uniformly fixed to each mounting position. The stirring rods 17 are also made of hollow metal tubing and welded to the hollow drive rod 15. The interior of each stirring rod 17 is connected to the hollow drive rod 15. Air blowing holes communicating with the interior are formed on the surface of the stirring rod 17 at the end away from the hollow drive rod 15 and on its lower surface. The diameter and number of air blowing holes are set according to actual drying requirements to ensure that hot air can be evenly blown onto the material inside the tank. Anti-clogging auxiliary components are installed on the surface of each stirring rod 17 corresponding to the air blowing hole position to prevent material from clogging the air blowing holes and affecting the drying effect.

[0022] The vibration assembly includes a square mounting plate 6 that is fitted to the side of the drying tank 1. The square mounting plate 6 is made of metal sheet. A horizontally arranged fixed support rod 9 is fixedly connected to the side of the fixed support rod 9 facing the drying tank 1 by bolts. A striking rod 7 is rotatably connected to the end of the fixed support rod 9 away from the square mounting plate 6 through a rotating shaft. The rotating shaft, the fixed support rod 9 and the striking rod 7 are all clearance fit to ensure that the striking rod 7 can rotate flexibly. An elastic impact block 8 is fixed to the end of the striking rod 7 near the drying tank 1 by adhesive bonding. The elastic impact block 8 is made of rubber to avoid damage to the drying tank 1 during impact. A rectangular block is bolted to the surface of the square mounting plate 6 and below the fixed support rod 9. A drive motor 10 is bolted to the top of the rectangular block. The drive motor 10 is a small speed-regulating motor with its output shaft set horizontally. An elliptical rotating block 11 is fixedly connected to the end of the output shaft by a key connection. The elliptical rotating block 11 is made of metal and its outer peripheral wall can abut against the end of the striking rod 7 away from the elastic impact block 8. The rotation of the elliptical rotating block 11 pushes the striking rod 7 to move.

[0023] A return spring 13 is fixedly connected to the side surface of the square mounting plate 6 facing the drying tank 1 and located between the fixed support rod 9 and the rectangular block by means of hooks or welding. The end of the return spring 13 away from the square mounting plate 6 is fixedly connected to the middle position of the striking rod 7. The return spring 13 is a metal spring with a certain elastic coefficient. When the return spring 13 is in the natural state, the elastic impact block 8 at the end of the striking rod 7 maintains a preset distance from the side wall of the drying tank 1, ensuring that the elliptical rotating block 11 can push the striking rod 7 to achieve the striking action when it rotates.

[0024] An arc-shaped groove is provided at the end of the striking rod 7 away from the elastic impact block 8. The curvature of the arc-shaped groove is adapted to the outer circumference of the elliptical rotating block 11. A horizontally arranged buffer shaft 12 is fixedly inserted inside the arc-shaped groove by welding. The buffer shaft 12 is made of metal round rod. When the elliptical rotating block 11 rotates, its outer circumference wall rolls against the outer circumference wall of the buffer shaft 12. The buffer shaft 12 reduces the friction between the elliptical rotating block 11 and the striking rod 7, thus extending the service life of the components.

[0025] The drying tank 1 has a long groove 2 extending vertically on its side, with the opening of the groove 2 facing outward. Inside the long groove 2, a threaded adjusting rod 3 is vertically mounted via a bearing. The top of the threaded adjusting rod 3 extends out of the long groove 2 and can be connected to a handwheel or motor for rotational drive. A sliding block 5 is threadedly connected to the outer peripheral wall of the threaded adjusting rod 3. The shape of the sliding block 5 matches the groove shape of the long groove 2 to ensure smooth sliding. The side of the sliding block 5 away from the bottom of the long groove 2 is fixedly connected to a square mounting plate 6 by bolts. When the threaded adjusting rod 3 rotates, it can drive the sliding block 5 to move vertically back and forth along the long groove 2, thereby driving the vibration component to move up and down to strike different height positions of the drying tank 1.

[0026] A stabilizing slide rod 4 extending vertically is fixedly assembled inside the elongated groove 2 and located on one side of the threaded adjusting rod 3 by welding. The stabilizing slide rod 4 is made of a metal round rod. The stabilizing slide rod 4 is arranged parallel to the threaded adjusting rod 3, and the outer peripheral wall of the stabilizing slide rod 4 is in sliding fit with the sliding hole opened on the sliding block 5. The sliding hole and the stabilizing slide rod 4 are in clearance fit, which guides the vertical movement of the sliding block 5 and prevents the sliding block 5 from failing to move smoothly as the threaded adjusting rod 3 rotates.

[0027] The auxiliary component includes a hollow protective rod 18 fixedly connected to the upper surface of the stirring support rod 17 and corresponding to the position of the air blowing hole. The hollow protective rod 18 is made of metal tube and welded to the stirring support rod 17. The axis of the hollow protective rod 18 is collinear with the axis of the air blowing hole, and the interior of the hollow protective rod 18 is connected to the air blowing hole to ensure that the gas can pass through smoothly. A limiting ring 19 is fixedly mounted inside the hollow protective rod 18 near the air blowing hole by welding. The limiting ring 19 is an annular metal ring with a central hole that allows gas to pass through. A support spring 20 is fixedly connected to the upper surface of the limiting ring 19 by welding or hooking. A sealing ball 21 is fixedly connected to the end of the support spring 20 away from the limiting ring 19. The sealing ball 21 is made of metal or hard plastic, and its outer diameter is adapted to the inner diameter of the hollow protective rod 18 to ensure that the sealing ball 21 can slide inside the hollow protective rod 18 and achieve a seal. When the support spring 20 is in its natural state, the sealing ball 21 can block the opening of the hollow protective rod 18 away from the air blowing hole to prevent material from entering the air blowing hole.

[0028] The end of the sealing ball 21 furthest from the supporting spring 20 is fixedly connected to an anti-blocking baffle 22 by adhesive bonding or threaded connection. The anti-blocking baffle 22 is made of metal or plastic sheet, and its diameter is larger than the outer diameter of the hollow protective rod 18. The anti-blocking baffle 22 is fitted against the end face of the hollow protective rod 18 furthest from the air blowing hole, further preventing material from approaching the opening of the hollow protective rod 18. A sealing ring is fixed to the side surface of the anti-blocking baffle 22 facing the hollow protective rod 18 by adhesive bonding. The sealing ring is made of rubber, and the end face of the hollow protective rod 18 furthest from the air blowing hole has an annular groove that matches the sealing ring. When the anti-blocking baffle 22 is fitted against the hollow protective rod 18, the sealing ring can be embedded in the annular groove to form a seal, enhancing the sealing effect and preventing fine particles of material from entering the interior of the hollow protective rod 18.

[0029] Working principle When using this drying device for processing chlorine-based compound fertilizer, the chlorine-based compound fertilizer material to be dried is first fed into the drying tank 1 through the feeding funnel 26. Then, the drive motor 14, the blower 16, and the drive motor 10 are started through the control panel 23. After the drive motor 14 starts, it drives the hollow transmission rod 15 to rotate. The hollow transmission rod 15 further drives each stirring support rod 17 to rotate inside the drying tank 1, which stirs the material in the tank and allows the material to be heated evenly. The gas generated after the blower 16 starts (and the heating component to generate hot gas if heating is required) is transported to the ventilation connection pipe 151 through the gas supply pipe 161, and then enters the hollow transmission rod 15 through the ventilation connection pipe 151. It is then distributed to the interior of each stirring support rod 17. Under the action of pressure, the gas pushes the sealing ball 21 to move upward against the elastic force of the support spring 20, causing the opening of the hollow protective rod 18 to open. The gas is then blown into the material in the tank through the air blowing hole, thus achieving the drying treatment of the material.

[0030] After the drive motor 10 starts, it drives the elliptical rotating block 11 to rotate. When the long axis end of the elliptical rotating block 11 abuts against the buffer round shaft 12, it pushes the striking rod 7 to rotate around the rotating shaft on the fixed support rod 9, causing the elastic impact block 8 to approach and impact the side wall of the drying tank 1, shaking off the material adhering to the tank wall. When the short axis end of the elliptical rotating block 11 rotates to the buffer round shaft 12, the striking rod 7 resets under the elastic force of the return spring 13, and the elastic impact block 8 separates from the side wall of the drying tank 1. As the elliptical rotating block 11 continues to rotate, the striking rod 7 continuously performs the striking and resetting actions, continuously shaking off the material adhering to the tank wall. At the same time, the sliding block 5 can be moved vertically along the long groove 2 by rotating the threaded adjusting rod 3. The sliding block 5 drives the square mounting plate 6 and the entire vibration assembly to move up and down, so that the elastic impact block 8 can strike the side wall of the drying tank 1 at different heights, ensuring that the material adhering to each position in the tank can be shaken off.

[0031] During the drying process, the anti-blocking baffle 22 and the sealing ring effectively prevent material from approaching the opening of the hollow protective rod 18, thus preventing material from entering the interior of the hollow protective rod 18. When the blower 16 stops supplying air, the support spring 20 returns to its natural state, pulling the sealing ball 21 back to its original position, sealing the opening of the hollow protective rod 18, further preventing material from entering the air vent and causing blockage. After drying is completed, all equipment is shut down, and the valve at the discharge port is opened, allowing the dried material to be discharged from the drying tank 1 through the discharge port.
