Description

Technical Field

[0001] This utility model belongs to the technical field of organic fertilizer processing equipment, specifically relating to a granulator in a production line for producing granular organic fertilizer. Background Technology

[0002] A modern granular organic fertilizer production line is a complex system integrating multiple stages such as pretreatment, fermentation, crushing, mixing, granulation, drying, cooling, screening, and packaging. The equipment selection and process control at each stage directly affect the quality and cost of the final product. Granulation, in particular, involves shaping mixed powdery materials into spherical particles of a certain strength and uniform size, facilitating storage, transportation, and application, and improving physical properties. Commonly used granulators include disc granulators, rotary drum granulators, and extrusion granulators. Disc granulators remain an important granulation device in the fertilizer industry due to their relatively simple structure, intuitive operation, good pelletizing effect, ease of observation and adjustment, and relatively low investment cost. Their core technology lies in utilizing the complex material movement generated by an inclined rotating disc to achieve rolling agglomeration into granules.

[0003] Despite their wide application, disc granulators also have some inherent drawbacks. For example, they easily generate dust during feeding, the initial stage of liquid spraying, and when granules overflow, leading to a deterioration of the production environment. Therefore, there is an urgent need to design a granulator for a production line producing granular organic fertilizer to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a granulator in a production line for producing granular organic fertilizer, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a granulator in a production line for producing granular organic fertilizer, comprising: The granulator body includes a disc and a base. A frame is fixed on the top of the base, and a bearing seat is fixed on the top of the frame. A rotating shaft is provided between the two bearing seats. A hopper is provided directly below the disc, and an electrical control box is provided on one side of the base. The spraying mechanism includes a liquid tank, a water pump, a DC regulated power supply and an atomizing nozzle facing the top of the disc, all located on the other side of the base. The water pump is connected to the liquid tank and the atomizing nozzle via water pipes, and the DC regulated power supply is connected to the conductive part of the atomizing nozzle via a high-voltage cable. The dust removal mechanism is located above the disc and includes a dust hood, a dust suction pipe, and a dust collector. The dust hood is connected to the dust collector through the dust suction pipe, and the opening of the dust hood faces the upper surface of the disc to collect the dust generated during the granulation process.

[0006] Furthermore, it also includes a tilt adjustment mechanism, which includes an electric telescopic rod, an adjusting rod, and a movable frame. The electric telescopic rod is fixed vertically to the top of the base. The movable frame is fixedly connected to the rotating shaft. The two ends of the adjusting rod are movably connected to the telescopic rod of the electric telescopic rod and the movable frame, respectively. A bearing seat two is fixed at the bottom of the movable frame. A main shaft is keyed into the bearing seat two. The other end of the main shaft is keyed to the center of the disc.

[0007] Furthermore, it also includes a transmission mechanism, which includes a motor and a reducer fixed to the top of the movable frame and connected by a belt (or chain). A small gear is keyed to the output shaft of the reducer, and a large gear ring is keyed to the main shaft. The small gear meshes with the large gear ring.

[0008] Furthermore, it also includes a feeding mechanism, which is a screw conveyor. The discharge end of the screw conveyor is flush with the bottom end of the disc, and a feeding hopper is fixed at the top of the feed end of the screw conveyor.

[0009] Furthermore, the granulator body also includes a mounting frame fixed to the movable frame, on which a scraper extending to the inner bottom surface of the disc is fixed.

[0010] Furthermore, the dust collector is a pulse bag filter.

[0011] Furthermore, the electrical control box is electrically connected to the water pump, DC regulated power supply, dust collector, electric telescopic rod, motor and screw conveyor respectively.

[0012] The technical effects and advantages of this utility model are as follows: The granulator in this production line for granular organic fertilizer is advanced in design, compact in structure, and easy to use. By incorporating a spraying mechanism, liquid material is evenly sprayed onto the material on the disc, promoting agglomeration into spheres. Simultaneously, a DC regulated power supply provides charge to the atomizing nozzles, causing the liquid material to form tiny charged droplets at the nozzles. Electrostatic adsorption further improves the mixing uniformity of the liquid and material. The dust removal mechanism promptly collects dust generated during the granulation process, maintaining a clean production environment and effectively solving the dust problem inherent in traditional disc granulators. Furthermore, this granulator, through the design of an angle adjustment mechanism, transmission mechanism, and feeding mechanism, achieves precise control over the disc angle, rotation speed, and feeding amount, further improving granulation efficiency and product quality.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] This utility model provides, for example Figs. 1-3The pelletizer shown in the production line for producing granular organic fertilizer includes: The granulator body 100 includes a disc 101 and a base 102. A frame 103 is fixed on the top of the base 102. A bearing seat 104 is fixed on the top of the frame 103. A rotating shaft 105 is provided between the two bearing seats 104. A hopper 106 is provided directly below the disc 101. An electrical control box 107 is provided on one side of the base 102. The spraying mechanism 200 includes a liquid tank 201, a water pump 202, a DC regulated power supply 203, and an atomizing nozzle 204 disposed on the top side of the disc 101, which are located on the other side of the base 102. The water pump 202 is connected to the liquid tank 201 and the atomizing nozzle 204 through water pipes, and the DC regulated power supply 203 is connected to the conductive part of the atomizing nozzle 204 through a high-voltage cable. The dust collection mechanism 300 is located above the disc 101 and includes a dust collection hood 301, a dust collection pipe 302, and a dust collector 303. The dust collection hood 301 is connected to the dust collector 303 via the dust collection pipe 302, and its opening faces the upper surface of the disc 101 to collect dust generated during the granulation process. Furthermore, a damper is installed inside the dust collection pipe 302, and its opening and closing are controlled by the electrical control box 107. This allows for adjustment of the suction power as needed, further improving dust collection efficiency. The dust collector 303 contains filter bags made of antistatic material, which not only effectively filter dust but also prevent safety hazards such as explosions caused by static electricity buildup. Additionally, the dust collector 303 is equipped with a cleaning system that maintains the permeability of the filter bags through regular cleaning, ensuring the continuous and efficient operation of the dust collector 303.

[0019] For example, see Fig. 3 As shown, it also includes a tilt adjustment mechanism 400, which includes an electric telescopic rod 401, an adjusting rod 402, and a movable frame 403. The electric telescopic rod 401 is fixed vertically to the top of the base 102. The movable frame 403 is fixedly connected to the rotating shaft 105. The two ends of the adjusting rod 402 are movably connected to the telescopic rod of the electric telescopic rod 401 and the movable frame 403, respectively. A bearing seat 2 404 is fixed at the bottom of the movable frame 403. A main shaft 405 is keyed into the bearing seat 2 404. The other end of the main shaft 405 is keyed to the center of the disc 101.

[0020] In this technical solution, the electric telescopic rod 401, through its telescopic movement, can drive the movable frame 403 and the connected disc 101 to adjust their angle around the rotating shaft 105, thereby adjusting the tilt angle of the disc 101. This tilt angle adjustment function helps optimize the rolling and agglomeration effect of materials on the disc 101, ensuring a more stable and efficient granulation process. Simultaneously, through precise control of the electric telescopic rod 401 by the electrical control box 107, fine-tuning of the disc 101's tilt angle can be achieved to meet different material characteristics and production needs.

[0021] For example, see Figs. 2-3 As shown, it also includes a transmission mechanism 500, which includes a motor 501 and a reducer 502 fixed to the top of the movable frame 403 and connected by a belt (or chain). A pinion 503 is keyed to the output shaft of the reducer 502, and a large gear ring 504 is keyed to the main shaft 405. The pinion 503 and the large gear ring 504 are meshed together.

[0022] In this technical solution, after the motor 501 starts, it drives the reducer 502 to run through belt (or chain) transmission. The reduction effect of the reducer 502 causes the pinion 503 on the output shaft to rotate at a suitable speed. The meshing connection between the pinion 503 and the large gear ring 504 ensures that the main shaft 405 can rotate synchronously, thereby driving the disc 101 to rotate at a stable speed. This transmission method is not only compact in structure and highly efficient in transmission, but also allows for precise control of the speed of the disc 101 by adjusting the reduction ratio of the reducer 502, so as to adapt to different material characteristics and production needs, and ensure the stability and efficiency of the granulation process.

[0023] For example, see Figs. 1-2 As shown, it also includes a feeding mechanism 600, which is a screw conveyor 601. The discharge end of the screw conveyor 601 is flush with the bottom end of the disc 101, and a feeding hopper 602 is fixed at the top of the feed end of the screw conveyor 601.

[0024] In this technical solution, after the screw conveyor 601 starts, it can continuously and stably transport materials to the bottom end of the disc 101, ensuring the continuity and stability of the granulation process. The conveying speed of the screw conveyor 601 can be adjusted through the electrical control box 107 to adapt to different material characteristics and production needs, further improving the flexibility and applicability of the granulator. In addition, the design of the discharge end of the screw conveyor 601 being flush with the bottom end of the disc 101 can avoid high-level drop feeding and reduce dust generated during the feeding process.

[0025] For example, see Fig. 1As shown, the granulator body 100 also includes a mounting bracket 108 fixed to the movable frame 403, and a scraper 109 extending to the inner bottom surface of the disc 101 is fixed on the mounting bracket 108.

[0026] In this technical solution, the scraper 109 helps to scrape the material adhering to the inner bottom surface of the disc 101 during its rotation, preventing excessive accumulation of material and ensuring that the material participates evenly and fully in the granulation process, thereby improving granulation efficiency and product quality. The scraper 109 is made of wear-resistant material, possessing excellent wear and corrosion resistance, and can maintain a sharp cutting edge for a long time, ensuring effective scraping. Simultaneously, the installation position and angle of the scraper 109 are precisely designed to minimize resistance to the rotation of the disc 101, ensuring stable operation of the granulator.

[0027] For example, dust collector 303 is a pulse bag dust collector.

[0028] In this technical solution, the pulse jet baghouse dust collector boasts advantages such as excellent dust removal effect, high dust collection efficiency, and stable operation, making it suitable for continuous and efficient granulation production. The pulse jet baghouse dust collector periodically injects high-pressure gas into the filter bags to remove dust adhering to their surface, maintaining filter bag permeability and ensuring the continuous and efficient operation of the dust collector 303. Simultaneously, the pulse jet baghouse dust collector is also equipped with components such as a compressed air storage tank and pulse valves. The opening and closing of the pulse valves are precisely controlled by the electrical control box 107, achieving precise control of the dust collection process and further improving dust collection efficiency and stability.

[0029] For example, the electrical control box 107 is electrically connected to the water pump 202, the DC regulated power supply 203, the dust collector 303, the electric telescopic rod 401, the motor 501 and the screw conveyor 601 respectively.

[0030] In this technical solution, the electrical control box 107 serves as the control center of the entire granulator, achieving precise control of various components through its internal circuitry and control system. The starting and stopping of the water pump 202, the adjustment of the spray volume, the stabilization of the output voltage and current of the DC regulated power supply 203, the regulation of the dust collector 303's cleaning frequency and dust removal efficiency, the control of the extension length and speed of the electric telescopic rod 401, the adjustment of the speed and direction of the motor 501, and the adjustment of the conveying speed of the screw conveyor 601 can all be precisely set and monitored in real time through the electrical control box 107. This centralized control design not only improves the automation level of the granulator but also ensures the coordinated work between various components, further improving granulation efficiency and product quality. Furthermore, the electrical control box 107 is equipped with a touchscreen human-machine interface, which can display the granulator's operating status and production parameters in real time, facilitating monitoring and adjustment by operators. The electrical control box 107 also has fault alarm and self-protection functions; once an abnormality is detected, it can immediately cut off the power to the relevant components to prevent the fault from escalating and ensure the safe operation of the granulator.

[0031] Working principle: When the granulator in the production line for producing granular organic fertilizer is in use, the tilt angle and speed of the disc 101 are first adjusted according to the actual material characteristics and production needs. Then, the screw conveyor 601 is started through the electrical control box 107 to continuously transport the material into the disc 101. At the same time, the water pump 202, the DC regulated power supply 203 and the dust collector 303 are started. The DC regulated power supply 203 causes the atomizing nozzle 204 to be charged. When the water flows through the atomizing nozzle 204, it breaks into extremely fine charged droplets. The charged droplets combine with the dust particles, and the dust settles through the weight increase and agglomeration. Some of the dust that cannot combine with the charged droplets in time enters the dust collector 303 through the dust suction hood 301 and the dust suction pipe 302. The granulator in this production line for granulated organic fertilizer features an advanced design, compact structure, and ease of use. A spray mechanism 200 evenly sprays liquid material onto the material on the disc 101, promoting agglomeration into granules. Simultaneously, a DC regulated power supply 203 provides charge to the atomizing nozzles 204, causing the liquid material to form tiny charged droplets at the nozzles. Electrostatic adsorption further improves the mixing uniformity of the liquid and material. A dust removal mechanism 300 promptly collects dust generated during granulation, maintaining a clean production environment and effectively solving the dust problem inherent in traditional disc granulators. Furthermore, the granulator utilizes tilt adjustment, transmission, and feeding mechanisms to achieve precise control over the disc tilt angle, rotation speed, and feeding amount, further improving granulation efficiency and product quality.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
