[0049] like Figure 1-Figure 3 As shown, the present invention provides a device for reducing the generation of large pellets in a disc pelletizing machine, comprising: a disc pelletizing machine 1; a feeding mechanism 2, arranged above the disc pelletizing machine 1, for conveying materials into the disc pelletizing machine 1; a crushing mechanism 3, arranged above the disc pelletizing machine 1, for crushing the large pellets in the disc pelletizing machine 1; a spraying mechanism 4, arranged above the disc pelletizing machine 1, for spraying water mist into the disc pelletizing machine 1; a vibrating mechanism 5, arranged in the disc pelletizing machine 1, for vibrating the materials in the disc pelletizing machine 1 and dispersing the materials; a control system, connected to the feeding mechanism 2, the crushing mechanism 3, the spraying mechanism 4 and the vibrating mechanism 5, the control system being used to control the feeding mechanism 2, the crushing mechanism 3, the spraying mechanism 4 and the vibrating mechanism 5, so as to reduce the generation of large pellets in the disc pelletizing machine.

[0050] The present invention includes a disc pelletizer 1 itself, a feeding mechanism 2, a crushing mechanism 3, a spraying mechanism 4, a vibrating mechanism 5 and a control system. These components work together to ensure that the generation of large pellets is effectively reduced during the pelletizing process. The disc pelletizer 1 is the core of the entire device. It is a large rotating disk used to form pellets by rolling and bonding the raw materials. The feeding mechanism 2 is located above the disc pelletizer 1 and is responsible for evenly conveying the raw materials into the disc. In order to ensure the uniform distribution of the raw materials, the feeding mechanism 2 usually includes one or more screw conveyors. The crushing mechanism 3 is also arranged above the disc pelletizer 1. Its function is to detect and crush those overly large pellets that have been formed to ensure that the large pellets are effectively crushed before entering the disc. The spraying mechanism 4 is located above the disc pelletizer 1 and is responsible for spraying water mist into the disc. The spraying of water mist helps to adjust the humidity of the raw materials, thereby controlling the bonding and hardening process of the pellets. The uniformity of the spray is crucial to ensure the quality of the pellets. The vibration mechanism 5 is arranged inside the disc pelletizing machine 1. Its function is to promote the dispersion and mixing of materials through vibration, and to help break up the oversized pellets that have been formed.

[0051] The control system is the brain of the whole device, which is connected with the feeding mechanism 2, the crushing mechanism 3, the spraying mechanism 4 and the vibration mechanism 5. The control system monitors and adjusts the working status of each mechanism through sensors and actuators to ensure that they operate according to the predetermined procedures and parameters. By accurately controlling the conveying speed, crushing degree, spraying amount and vibration intensity of the raw materials, the control system can effectively reduce the generation of large pellets and improve the pelletizing efficiency and pellet quality.

[0052] This device achieves effective control over the formation of large pellets in the disc pelletizing machine by comprehensively using a variety of technical means, thereby improving the efficiency of the pelletizing process and the quality of the product.

[0053] In some embodiments of the present application, the feeding mechanism 2 includes a material bin 21, a feeding valve 22, a screw conveyor 23 and a material flow meter 24; the screw conveyor 23 is connected to the outlet of the material bin 21, the feeding valve 22 is arranged at the outlet of the material bin 21, the feeding valve 22 is used to control the material flow, the material flow meter 24 is arranged at the outlet of the screw conveyor 23, and the material flow meter 24 is used to detect the real-time material flow transported by the screw conveyor 23.

[0054] The feeding mechanism 2 includes a material bin 21, a feeding valve 22, a screw conveyor 23 and a material flow meter 24; the screw conveyor 23 is connected to the outlet of the material bin 21 to ensure that the material can be smoothly transferred from the material bin 21 to the screw conveyor 23. In order to accurately control the flow of the material, the feeding valve 22 is arranged at the outlet of the material bin 21. The feeding valve 22 can be a valve controlled manually or automatically, which is used to adjust the outflow rate of the material, thereby controlling the material flow. In addition, the material flow meter 24 is arranged at the outlet of the screw conveyor 23. The material flow meter 24 is a device for detecting and measuring the flow of materials through the conveyor. It can be a sensor based on weight, volume or other physical principles. The material flow meter 24 is used to monitor the material flow conveyed by the screw conveyor 23 in real time to ensure the stable supply of materials, which is crucial to the continuity and accuracy of the entire production process. Through the collaborative work of these components, accurate control and monitoring of the material flow can be achieved, thereby improving the efficiency and quality of the entire production process.

[0055] In some embodiments of the present application, the crushing mechanism 3 includes a support rod 31, a crushing plate 32, a crushing knife 33 and a lifter 34. The support rod 31 is arranged above the disc pelletizing machine 1, the crushing plate 32 is connected to the support rod 31, the crushing knife 33 is installed at the bottom of the crushing plate 32, and the lifter 34 is connected to the support rod 31. The lifter 34 is used to control the lifting distance of the support rod 31; a plurality of crushing knives 33 are provided, and the crushing knives 33 are installed at the bottom of the crushing plate 32 in an inclined state.

[0056] The crushing mechanism 3 includes a support rod 31, a crushing plate 32, a crushing knife 33 and a lifter 34, which work together to achieve effective crushing of the material. The support rod 31 is arranged above the disc pelletizer 1. It serves as the main supporting structure of the entire crushing mechanism 3, ensuring that the crushing plate 32 and the crushing knife 33 can be firmly installed and work. The crushing plate 32 is connected to the support rod 31. It is a solid platform for carrying the crushing knife 33 and evenly transmitting the crushing force to the crushing knife 33.

[0057] The crushing knives 33 are installed at the bottom of the crushing plate 32. They are the parts of the crushing mechanism 3 that directly contact the material and are responsible for cutting and crushing the material. There are several crushing knives 33, which are installed at the bottom of the crushing plate 32 in an inclined shape. This design can improve the crushing efficiency because the inclined blades can cut the material better and generate a certain propulsion force during the crushing process, which is conducive to further crushing and discharge of the material.

[0058] The lifter 34 is connected to the support rod 31 and is an adjustable device for controlling the lifting distance of the support rod 31. By adjusting the lifter 34, the height of the crushing plate 32 and the crushing knife 33 relative to the disc pelletizer 1 can be changed to meet the crushing requirements of materials of different sizes and hardness. The use of the lifter 34 makes the crushing mechanism 3 more flexible and can adapt to different working conditions and requirements.

[0059] In some embodiments of the present application, the spray mechanism 4 includes a liquid storage tank 41, a water pump 42, a spray head 43 and a liquid flow meter 44; the inlet of the water pump 42 is connected to the liquid storage tank 41, the spray head 43 is connected to the outlet of the water pump 42, and the liquid flow meter 44 is arranged at the inlet of the spray head 43, and the liquid flow meter 44 is used to detect the real-time liquid flow of the spray head 43.

[0060] The spray mechanism 4 includes a liquid storage tank 41, a water pump 42, a spray head 43 and a liquid flow meter 44; the inlet of the water pump 42 is connected to the liquid storage tank 41 to ensure that the water pump 42 can extract liquid from the storage tank. The outlet of the water pump 42 is connected to the spray head 43, so that the liquid pressurized by the water pump 42 can be sprayed out through the spray head 43. In order to accurately control and monitor the liquid flow during the spraying process, the liquid flow meter 44 is arranged at the inlet of the spray head 43. The liquid flow meter 44 is responsible for real-time detection of the liquid flow through the spray head 43 to ensure the accuracy and efficiency of the spray. In this way, the spray mechanism 4 can adjust the spray volume as needed to adapt to different spraying requirements and environmental conditions.

[0061] In some embodiments of the present application, the vibration mechanism 5 includes an ultrasonic vibrator 51, which is arranged on the side wall of the disc pelletizing machine 1. The ultrasonic vibrator 51 is used to vibrate the material on the side wall of the disc pelletizing machine 1 and disperse the material accumulated on the side wall.

[0062] The vibration mechanism 5 includes an ultrasonic vibrator 51, which is installed on the side wall of the disc pelletizer 1. Its main function is to apply vibration to the material on the side wall of the disc pelletizer 1, effectively preventing the material from accumulating and agglomerating on the side wall. By accurately controlling the vibration frequency and amplitude of the ultrasonic vibrator 51, the material can be finely dispersed to ensure that the material is evenly distributed during the pelletizing process, thereby improving the pelletizing efficiency and pellet quality. In addition, this vibration mechanism also helps to reduce the adhesion of materials during the pelletizing process, reduce the frequency and difficulty of cleaning and maintenance, and thus improve the operating efficiency and service life of the entire pelletizer.

[0063] In some embodiments of the present application, the control system includes an acquisition module, a processing module and a control module; the acquisition module is used to acquire the operating information of the disc pelletizing machine 1 during operation, and the operating information includes a pellet image, a real-time material flow rate and a real-time liquid flow rate; the processing module is connected to the acquisition module, and the processing module is used to receive the operating information and set the operating parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating information; the control module is connected to the processing module, and the control module is used to control the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating parameters set by the processing module.

[0064] It can be seen that this solution realizes the real-time acquisition of the operation information of the disc pelletizing machine 1, including the pellet image, real-time material flow and real-time liquid flow, which is helpful for comprehensive monitoring of the equipment status. By analyzing the received operation information through the processing module, the operation parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 can be adjusted in time to optimize the production process. The control module performs precise control according to the operation parameters set by the processing module, which improves the automation level and operation efficiency of the disc pelletizing machine 1. The modular design of the system improves maintainability and scalability, and facilitates fault diagnosis and upgrading. It improves the consistency and stability of the pellet quality, reduces waste in the production process, and improves production efficiency.

[0065] In some embodiments of the present application, the processing module sets the operating parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating information, including: processing the pellet image to determine the number of pellets in the pellet image and the number of large pellets with a diameter greater than the standard pellet diameter; determining the detection time interval; determining the required material flow rate and the required liquid flow rate according to the detection time interval and the number of pellets; determining the material flow rate difference between the required material flow rate and the real-time material flow rate, and setting the opening of the feed valve 22 and the operating frequency of the screw conveyor 23 according to the material flow rate difference; determining the liquid flow rate difference between the required liquid flow rate and the real-time liquid flow rate, and setting the speed of the water pump 42 according to the liquid flow rate difference.

[0066] During the operation of the disc pelletizer 1, there is a close relationship between the generation of pellets and the material flow rate and liquid flow rate. The material flow rate directly affects the number and size of the pellets: the material flow rate is a direct factor that determines the number and size of the pellets. When the material flow rate increases, if other conditions remain unchanged (such as moisture content, disc speed, etc.), the number of pellets will usually increase, but the size of a single pellet may decrease due to the extrusion and collision between materials. On the contrary, when the material flow rate decreases, the number of pellets will decrease, but the size of a single pellet may increase due to the relatively loose environment between materials. And the amount of material flow rate will also affect the quality of the raw balls. When the material flow rate is too much, some materials may not be fully wetted and rolled into balls, thereby affecting the uniformity and strength of the raw balls. When the material flow rate is moderate, it can ensure that each material particle is fully wetted and rolled, thereby improving the quality of the raw balls. The liquid flow rate determines the humidity and cohesion of the pellets: the liquid flow rate is a key factor in controlling the humidity of the pellets. An appropriate amount of water mist can promote the adhesion between material particles, making the pellets more compact and stable. However, if the liquid flow rate is too large, the pellets will be too wet, and easily stick and agglomerate; while if the liquid flow rate is too small, the pellets will be dry and loose, and it will be difficult to form a stable structure. The liquid flow rate also affects the growth rate of the green balls. Under the appropriate liquid flow rate, the green balls can grow rapidly and reach the required particle size range. However, if the liquid flow rate is insufficient or excessive, it will affect the growth rate and final quality of the green balls. Therefore, the material flow rate and liquid flow rate are adjusted by analyzing the number of pellets detected.

[0067] In some embodiments of the present application, the processing module sets the operating parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating information, and also includes: comparing the number of large pellets with the preset number of large pellets. If the number of large pellets is greater than or equal to the preset number of large pellets, the lifter 34 is controlled to drive the support rod 31 to descend to crush the large pellets; wherein, after the support rod 31 descends, the distance between the crushing plate 32 and the bottom of the disc pelletizing machine 1 is the diameter of the standard pellet.

[0068] The processing module sets the operating parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating information, and also includes: comparing the number of large pellets with the preset number of large pellets. If the number of large pellets is greater than or equal to the preset number of large pellets, the lifter 34 is controlled to drive the support rod 31 to descend to crush the large pellets; wherein, after the support rod 31 descends, the distance between the crushing plate 32 and the bottom of the disc pelletizing machine 1 is the diameter of the standard pellet. The processing module further includes: if the number of large pellets is less than the preset number of large pellets, the lifter 34 is controlled to drive the support rod 31 to rise to avoid unnecessary crushing of small pellets or standard pellets. In addition, the processing module is also responsible for monitoring the working status of the crushing mechanism 3 to ensure that it operates within the normal parameter range to ensure the crushing effect and equipment safety. The entire system ensures the efficiency and stability of the pelletizing process through real-time monitoring and dynamic adjustment.

[0069] In some embodiments of the present application, the processing module sets the operating parameters of the feeding mechanism 2, the crushing mechanism 3, the spray mechanism 4 and the vibration mechanism 5 according to the operating information, including: processing the pellet image to determine the material thickness accumulated on the side wall of the disc pelletizing machine 1 in the pellet image; and setting the vibration frequency of the ultrasonic vibrator 51 according to the material thickness.

[0070] like Figure 4 As shown, the present invention also discloses a method for reducing the generation of large pellets in a disc pelletizing machine, which is applied to the above-mentioned device for reducing the generation of large pellets in a disc pelletizing machine, comprising:

[0071] Obtain the operation information of the disc pelletizing machine during operation, including pellet images, real-time material flow, and real-time liquid flow.

[0072] The operating parameters of the feeding mechanism, crushing mechanism, spray mechanism and vibration mechanism are set according to the operating information.

[0073] The feeding mechanism, crushing mechanism, spray mechanism and vibration mechanism are controlled according to the set operating parameters to reduce the generation of large pellets in the disc pelletizing machine.

[0074] By reducing the generation of large pellets, the disc pelletizing machine 1 can operate more efficiently, thereby increasing the output of the entire production line. Reducing the generation of large pellets means reducing unnecessary energy consumption, thereby reducing production costs and helping to produce more uniform and high-quality pellets to meet higher industrial standards and customer requirements.

[0075] By precisely controlling the feeding, crushing, spraying and vibration mechanism 5 through the control system, the automation of the production process is realized, manual intervention is reduced, and the convenience and accuracy of operation are improved. The system can obtain the operation information of the disc pelletizing machine 1 in real time, and dynamically adjust the operation parameters according to this information to ensure the stability and reliability of the production process. By precisely controlling the flow of materials and liquids, resources can be better utilized, waste can be reduced, and economic benefits can be improved.

[0076] It can be seen that this method for reducing the generation of large pellets in the disc pelletizing machine can not only improve production efficiency and product quality, but also reduce energy consumption and maintenance costs, while enhancing the automation and flexibility of the production process, bringing significant economic and environmental benefits to the enterprise.
