Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a fertilizer granule cooler. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material bases for agricultural production and mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrated organic fertilizers.

[0003] After drying, fertilizer granules need to be cooled. The cooling process involves feeding the fertilizer granules into a drum-type cooler, where they are cooled through heat exchange or by introducing airflow. However, this method involves unidirectional rotation and single-sided air intake and exhaust, which is not conducive to the mixing of airflow and fertilizer granules, resulting in uneven cooling and poor performance. Therefore, we propose a fertilizer granule cooler with improved cooling effect to address this deficiency in the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fertilizer pellet cooler.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fertilizer granule cooler includes a cooling outer cylinder. A screen cylinder is rotatably sealed between the left and right side walls of the inner cavity of the cooling outer cylinder. A drive assembly is provided on the cooling outer cylinder, which drives the screen cylinder to rotate. A hollow rotating rod rotates between the left and right sides of the cooling outer cylinder and passes through it. A servo motor is provided outside the cooling outer cylinder to drive the hollow rotating rod to rotate. The hollow rotating rod is located inside the screen cylinder and is concentrically positioned. Multiple stirring plates are distributed at equal intervals along the outer circumference of the hollow rotating rod. The surface of the mixing plate is evenly distributed with air holes. There are multiple hollow rings with the same center as the screen cylinder between the cooling outer cylinder and the screen cylinder. Air jets are connected to the inner wall of the hollow rings at equal intervals. An air supply assembly is provided between the hollow rings and the hollow rotating rod. The upper left side of the cooling outer cylinder is provided with a feed pipe that passes through the screen cylinder at one end. The lower right side of the cooling outer cylinder is provided with a discharge pipe that passes through the screen cylinder at one end and is attached to the bottom wall of the screen cylinder. The bottom of the cooling outer cylinder is connected to an exhaust and discharge pipe.

[0007] Using the above technical solution, fertilizer granules requiring cooling are stored in the screen cylinder through the feed pipe. Simultaneously, the screen cylinder is rotated by a drive component, while a servo motor drives the stirring plate on the hollow rotating rod to rotate in the opposite direction to the screen cylinder. This forward and reverse rotation of the screen cylinder and the stirring plate effectively tumbles and tumbles the fertilizer granules inside. During this tumbling process, airflow is supplied through the air supply component. The interconnectedness of the air supply component, hollow ring, hollow rotating rod, jet nozzle, stirring plate, and air holes ensures that the airflow, while stirring the fertilizer granules, is fully contacted and cooled through the air holes. Simultaneously, airflow exits from the jet nozzle on the hollow ring, circling and blowing air around the outside of the screen cylinder, achieving internal and external exhaust and contact cooling of the fertilizer granules, further improving the cooling effect. Meanwhile, powder particles are discharged from the holes of the screen cylinder, along with the airflow, through the exhaust and discharge pipe. The discharge pipe discharges the cooled, shaped fertilizer granules.

[0008] As a preferred embodiment of this utility model, the bottom of the cooling outer cylinder is provided with a support base.

[0009] By adopting the above technical solution, the support base provides support for the entire device.

[0010] As a preferred embodiment of the present invention, the driving assembly includes a gear ring disposed outside the screen cylinder and a driving motor disposed outside the cooling outer cylinder, wherein the output shaft of the driving motor is provided with a gear disc that meshes with the gear ring.

[0011] Using the above technical solution, the drive motor drives the gear disc to rotate and mesh with the gear ring, thereby synchronously driving the screen cylinder to rotate.

[0012] As a preferred embodiment of this utility model, the hollow rings are distributed at equal intervals laterally.

[0013] By adopting the above technical solution, the uniform distribution of hollow rings is ensured, thus guaranteeing the exhaust distribution effect.

[0014] As a preferred embodiment of this utility model, the air supply assembly includes a hollow ring seat rotatably connected to the outside of the hollow rotating rod and a connecting pipe connected to the outside of the hollow ring. A rigid pipe is connected between the connecting pipe and the hollow ring seat, and a blower is connected to the outside of the rigid pipe.

[0015] Using the above technical solution, while the blower is working and exhausting air, the airflow is discharged into the hollow rotating rod and hollow ring by utilizing the interconnection between the blower, rigid pipe, connecting pipe, hollow ring seat, hollow rotating rod and hollow ring.

[0016] As a preferred embodiment of this utility model, the bottom end of the exhaust unloading pipe is connected to a powder storage base, and the outside of the powder storage base is connected to an exhaust fan.

[0017] By adopting the above technical solution, while the exhaust fan is working to draw and exhaust air, the interconnection between the exhaust fan, the powder storage seat and the exhaust unloading pipe promotes the powder discharge and exhaust speed of the exhaust unloading pipe, and realizes the storage of powder in the powder storage seat.

[0018] As a preferred embodiment of this utility model, a dust filter is provided at the connection between the exhaust fan and the powder storage base.

[0019] By adopting the above technical solution, the dust filter screen prevents dust from entering the exhaust fan and causing damage to the exhaust fan's operation.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] 1. This fertilizer granule cooler, through a feed pipe, stores the fertilizer granules to be cooled into a screen cylinder. A drive assembly rotates the screen cylinder, while a servo motor drives a stirring plate on a hollow rotating rod to rotate in the opposite direction to the screen cylinder. This forward and reverse rotation of the screen cylinder and stirring plate effectively tumbles and tumbles the fertilizer granules inside. During this tumbling process, airflow is supplied through an air supply assembly. The interconnectedness of the air supply assembly, hollow ring, hollow rotating rod, jet nozzle, stirring plate, and air holes ensures that the stirring plate effectively tumbles and tumbles the fertilizer granules. During granulation, airflow is discharged through the air holes to fully contact and cool the fertilizer granules being stirred inside. At the same time, airflow is discharged from the jet nozzles on the hollow ring to circulate and blow air around the outside of the screen cylinder, achieving internal and external exhaust and contact cooling with the fertilizer granules to further improve the cooling effect. Meanwhile, powder particles are discharged from the holes of the screen cylinder and discharged together with the airflow through the exhaust discharge pipe. The discharge pipe is set to discharge the cooled and shaped fertilizer granules, avoiding the problem that the airflow and heat exchange of traditional drum-type coolers cannot fully mix and contact the fertilizer granules, thus failing to achieve good cooling uniformity and cooling effect.

[0022] 2. This fertilizer granule cooler, while the exhaust fan is working to draw in and exhaust air, utilizes the interconnection between the exhaust fan, the powder storage seat, and the exhaust discharge pipe to promote the powder discharge and exhaust speed of the exhaust discharge pipe, and to realize the storage of powder in the powder storage seat.
