Description

Technical Field

[0001] This application relates to the technical field of fertilizer processing equipment, and in particular to a cooling device for fertilizer production. Background Technology

[0002] In fertilizer production, processes such as granulation and drying significantly raise the temperature of materials. If not cooled in time, this can lead to material clumping and spoilage, affecting nutrient stability and product packaging quality, and may even pose safety hazards. Therefore, cooling equipment is an indispensable and crucial component of fertilizer production lines.

[0003] Traditional drum-type coolers mostly use a single drum structure. The material moves inside the drum by gravity and lifting plates. The contact area between the material and the cooling air is limited, resulting in low heat exchange efficiency, long cooling time, and high energy consumption. The material inside the drum is prone to accumulation and stratification. Large particles settle to the bottom, while fine powder floats on the top, causing uneven fertilizer processing.

[0004] Regarding the aforementioned technologies, the applicant believes that there is a defect of uneven fertilizer treatment. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a cooling device for fertilizer production.

[0006] This application provides a cooling device for fertilizer production, which adopts the following technical solution: A cooling device for fertilizer production includes a feeding mechanism, a roller mechanism, a cooling air mechanism, multiple sets of transmission mechanisms, a discharging mechanism, and a frame. The feeding mechanism is mounted on the frame on one side of the roller mechanism and is detachably connected to the roller mechanism. The roller mechanism is mounted on the frame and is rotatably connected to the frame. The roller mechanism is inclined. The cooling air mechanism is mounted on the feeding mechanism and is detachably connected to the feeding mechanism. The transmission mechanism is located between the frame and the roller mechanism and is detachably connected to the frame. The transmission mechanism provides power to the roller mechanism. The discharging mechanism is mounted on the frame at the other end of the roller mechanism and is detachably connected to the frame.

[0007] By adopting the above technical solution, the feeding mechanism is installed on the frame on one side of the roller mechanism. The roller mechanism is set at an inclination, so that the fertilizer slides naturally along the axis of the roller under the action of gravity. At the same time, the rotation of the roller realizes the tumbling and conveying of the material. When the roller rotates, the material generates a speed difference due to the difference in diameter, which enhances the mixing and dispersion effect and expands the contact area with the cooling air. The cooling air mechanism is installed at the air inlet of the first baffle at the feeding end, providing directional high-speed cooling air, which blows the material in the opposite direction along the inclination of the roller, so that the fertilizer is cooled at multiple angles and on the entire surface. The discharging mechanism is installed on the frame at the other end of the roller mechanism, which stirs the cooled material to make the fertilizer uniformly processed.

[0008] Preferably, the feeding mechanism includes a first baffle, which is rotatably connected to the roller mechanism and detachably connected to the frame. The upper part of the first baffle is provided with a feeding port, in which a screw feeder is installed. Air inlets are provided at both ends of the first baffle below the feeding port.

[0009] By adopting the above technical solution, the first baffle rotates synchronously with the drum, avoiding the problems of material leakage or friction and wear caused by the gap between the traditional fixed feed port and the rotating drum. The rotation of the spiral blades can push the material evenly from the feed port into the drum, avoiding the uneven material accumulation or material rushing phenomenon caused by traditional gravity feeding. The air inlet is set at both ends of the baffle below the feed port, forming a transverse airflow that is perpendicular or obliquely intersecting with the direction of material falling, ensuring that the material is fully in contact with the cold air as soon as it enters the drum.

[0010] Preferably, the roller mechanism includes an upper roller, a lower roller, and a connecting device. The diameter of the upper roller is larger than that of the lower roller. The connecting device is installed on the frame between the upper roller and the lower roller. The connecting device is detachably connected to the frame. The connecting device is truncated cone-shaped. Both the upper roller and the lower roller are rotatably connected to the connecting device.

[0011] By adopting the above technical solution, the diameter of the upper roller is larger than that of the lower roller. Both the upper and lower rollers are rotatably connected to the connecting device, so that the material is scattered and rolled between the two rollers due to the speed difference. The larger diameter reduces the material flow rate and prolongs the residence time of the high-temperature fertilizer in the critical cooling stage, thus achieving sufficient heat exchange. The smaller diameter increases the falling speed of the material and avoids over-cooling.

[0012] Preferably, the upper and lower rollers are provided with spiral shovels with the same direction of rotation inside, and the spiral shovels are detachably connected to the upper and lower rollers. A first gear is provided on the outside of the upper roller near the feeding mechanism and is fixedly connected to the upper roller. A second gear is provided on the outside of the lower roller near the discharging mechanism and is fixedly connected to the lower roller.

[0013] By adopting the above technical solution, the spiral shovels inside the upper and lower rollers rotate in the same direction, ensuring that the material moves in the same direction from the feed end to the discharge end, avoiding material stagnation or back mixing caused by the opposite rotation direction of traditional double rollers. While pushing the material, the spiral shovels continuously scatter fertilizer granules, increasing the contact area with the cold air. The first gear and the second gear drive the upper roller and the lower roller respectively.

[0014] Preferably, the cooling air mechanism includes multiple sets of high-pressure centrifugal fans, which are installed at the air inlet of the first baffle and are detachably connected to the first baffle.

[0015] By adopting the above technical solution, the high-pressure airflow generated by the centrifugal fan can penetrate the fertilizer accumulation layer, and the multiple sets of fans at the air inlet can be controlled in zones to form an airflow gradient that is strong in the front and weak in the back, matching the material temperature change curve.

[0016] Preferably, the transmission mechanism includes a reduction mechanism, a main gear, and a first motor. The first motor is connected to the main gear through the reduction mechanism and provides power to the main gear. The two sets of main gears of the transmission mechanism respectively cooperate with the first gear and the second gear to rotate.

[0017] Preferably, the discharge mechanism includes a second baffle, the bottom of which is provided with a discharge port, and the middle part of the second baffle above the discharge port is provided with a spiral stirring mechanism. One end of the spiral stirring mechanism is rotatably connected to the second baffle, and the other end of the spiral stirring mechanism is rotatably connected to the first baffle.

[0018] Preferably, the spiral stirring mechanism includes a second motor and a worm gear mechanism. One end of the worm gear mechanism is installed inside the first baffle and is rotatably connected to the first baffle. The other end of the worm gear mechanism is installed on the second baffle. The screw mechanism is rotatably connected to the second baffle. The second motor is connected to the worm gear mechanism and provides power to the worm gear mechanism. The second motor is installed outside the second baffle and is detachably connected to the second baffle. The rotation direction of the worm gear mechanism is opposite to that of the spiral shovel.

[0019] By adopting the above technical solution, the worm gear mechanism is installed between the first baffle and the second baffle. The spiral shovels in the upper and lower rollers push the material forward, while the worm gear mechanism generates a reverse shearing force when it rotates in the opposite direction, which effectively breaks up the clumped fertilizer and increases the cooling area of ​​the fertilizer.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The upper roller has a larger diameter than the lower roller. Both the upper and lower rollers are rotatably connected to the connecting device, which causes the material to be scattered and tumbled between the two rollers due to the speed difference. The larger diameter reduces the material flow rate and prolongs the residence time of the high-temperature fertilizer in the critical cooling stage, allowing for sufficient heat exchange. The smaller diameter increases the falling speed of the material and avoids over-cooling.

[0021] The worm gear mechanism is installed between the first baffle and the second baffle. The spiral shovels inside the upper and lower rollers push the material forward, while the worm gear mechanism generates a reverse shearing force when it rotates in the opposite direction, effectively breaking up the clumped fertilizer and increasing the cooling area of ​​the fertilizer.

The drum mechanism 2 and the spiral stirring mechanism 52 work together to enhance the stirring and dispersing effect and increase the contact area with the cooling air to make the fertilizer treatment uniform.
