Description

Technical Field

[0001] This utility model relates to a pelletizing disc, belonging to the technical field of sintering machine maintenance equipment. Background Technology

[0002] In modern pelleting industry, pelletizing discs are key equipment for forming green pellets with a certain strength and particle size from powdered materials. Their performance directly affects the quality of pellet products and the efficiency of the entire production process. With the increasing demands for pellet quality from industries such as steel, the limitations of traditional pelletizing discs are becoming increasingly apparent.

[0003] Traditional pelletizing discs face numerous challenges during operation. On one hand, the diversity and volatility of raw material properties pose a significant challenge. Different batches of raw materials exhibit substantial differences in particle size distribution, moisture content, mineral composition, and physicochemical properties such as viscosity. For instance, when raw material particle size is uneven, the rolling and agglomeration behaviors of large and small particles differ during pelletizing, easily leading to significant variations in green pellet size. Excessive moisture content in the raw materials results in overly damp green pellets, which are prone to deformation and adhesion during subsequent handling and processing, and may crack or burst during drying and roasting due to rapid moisture evaporation. Changes in raw material viscosity affect the bonding force between materials, thereby impacting the strength of the green pellets.

[0004] On the other hand, existing pelletizing disc adjustment methods largely rely on manual experience. Operators need to manually adjust the pelletizing disc's rotation speed, tilt angle, and water spray volume using the water supply device, based on their experience and observation of the production process. However, manual operation suffers from significant lag and inaccuracy. During production, changes in raw material properties can occur in real time and rapidly, making it difficult for humans to detect and make accurate adjustments immediately. This lag and inaccuracy not only leads to unstable quality of the produced green pellets and an increased defect rate but also affects subsequent pellet roasting and forming processes, reducing the efficiency of the entire production process. Furthermore, manual operation requires a significant workforce, increasing the company's labor costs.

[0005] In summary, existing pelletizing discs are ill-suited to fluctuations in raw material conditions and cannot meet the demands for efficient and high-quality pellet production. Summary of the Invention

[0006] The purpose of this invention is to provide a pelletizing disc that uses pressure sensors installed on the edge of the disc to capture real-time pressure changes as green pellets roll within it. An advanced control system then automatically and precisely adjusts the disc's rotation speed, tilt angle, and water spray volume based on this data. This effectively solves the problem of existing pelletizing discs failing to consistently produce green pellets with uniform particle size and acceptable strength when faced with fluctuations in raw material properties and humidity. The invention comprehensively improves the production efficiency and product quality of the pelletizing disc, reduces manual intervention costs, and addresses the aforementioned problems in the background technology.

[0007] The technical solution of this utility model is: a pelletizing disc, comprising a pelletizing disc body, a pressure sensor and a control system. The pelletizing disc body includes a disc body, a rotation drive device, a tilt adjustment device and a water filling device. The pressure sensor is installed on the edge of the disc body and is electrically connected to the control system. The control system is electrically connected to the rotation drive device, the tilt adjustment device and the water filling device respectively.

[0008] The disc is located at the center of the pelletizing disc body. The rotation drive device is connected to the bottom of the disc, the tilt adjustment device is connected to the side of the disc, and the nozzle of the water filling device is located above the disc.

[0009] The number of pressure sensors is one or more, and the pressure sensors are evenly distributed on the edge of the disc.

[0010] The control system has preset algorithms and models. The control system judges the pressure signal of the pressure sensor by the fluctuation range exceeding the set ±[5]%.

[0011] The control system controls the rotary drive device to adjust the speed within a range of 8-25 revolutions per minute.

[0012] The control system controls the tilt angle adjustment device to adjust the disc tilt angle within a range of 40°-60°.

[0013] The control system adjusts the water spray volume of the water supply device within the range of 8%-12% of the pellet moisture content.

[0014] The beneficial effects of this invention are as follows: By installing pressure sensors on the edge of the disc, the pressure change data generated when the green pellets roll in the disc is captured in real time. With the help of an advanced control system, the rotation speed, tilt angle and water spray volume of the pelletizing disc are automatically and accurately adjusted based on these data. This effectively solves the problem that existing pelletizing discs are unable to stably produce green pellets with uniform particle size and qualified strength when faced with fluctuations in raw material properties, humidity and other conditions. This comprehensively improves the production efficiency and product quality of the pelletizing disc and reduces the cost of manual intervention. Attached Figure Description

Obviously, the described implementation cases are only a small part of this utility model, not all of them. All other implementation cases obtained by those skilled in the art based on the implementation cases of this utility model without creative effort are within the protection scope of this utility model.

The pelletizing disc body 1 includes a disc body 2, a rotation drive device 3, a tilt adjustment device 4, and a water filling device 5. The pressure sensor 6 is installed on the edge of the disc body 2 and is electrically connected to the control system 7. The control system 7 is electrically connected to the rotation drive device 3, the tilt adjustment device 4, and the water filling device 5, respectively.

[0019] The number of pressure sensors 6 is one or more, and the pressure sensors 6 are evenly distributed on the edge of the disc body 2.

[0020] The control system 7 has a preset algorithm and model. The control system 7 judges the pressure signal of the pressure sensor 6 by the fluctuation range exceeding the set ±[5]%.

[0021] The control system 7 controls the rotary drive device 3 to adjust the speed within a range of 8-25 revolutions per minute.

[0022] The control system 7 controls the tilt angle adjustment device 4 to adjust the disc tilt angle within a range of 40°-60°.

[0023] The control system 7 controls the water spray volume of the water adding device 5 to be adjusted within the range of 8%-12% of the pellet moisture content.

[0024] In practical applications, multiple pressure sensors 6 are evenly installed along the edge of the disc 2, and the pressure sensors 6 are electrically connected to the control system 7. The pressure sensors 6 monitor the pressure changes generated when the green balls roll in the disc in real time and transmit the pressure signals to the control system 7.

[0025] The control system 7 receives the pressure signal from the pressure sensor 6; it analyzes and processes the pressure signal, and through the preset algorithm and model, it judges the state of the green pellets and the changes in the properties of the raw materials, humidity and other conditions, and sends corresponding control commands to the drive device 3, the tilt adjustment device 4 and the water addition device 5. The control system is based on a preset algorithm and model derived from a large amount of experimental data. When the pressure signal fluctuation range exceeds the set ±[5]%, it judges that the green pellet size or strength may not meet the requirements.

[0026] The drive unit 3 is connected to the disc body 2. When the control system 7 determines that the rotation speed of the pelletizing disc needs to be adjusted based on the pressure data, the drive unit 3 receives the control signal from the control system 7 and adjusts the rotation speed of the disc body 2 to a suitable speed, which is adjusted within the range of 8-25 revolutions per minute.

[0027] The tilt adjustment device 4 is connected to the disc body 2. When the control system 7 determines that the tilt angle of the disc body 2 needs to be adjusted, the tilt adjustment device 4 receives the control signal sent by the control system 7 and adjusts the tilt angle of the disc body 2 to a suitable size. The tilt angle is adjusted within the range of 40° - 60°.

[0028] The water supply device 5 can adjust the water volume. When the control system 7 determines that the water spray volume needs to be adjusted based on the pressure data, the water supply device 5 receives the control signal from the control system 7 and adjusts the water flow to a suitable flow rate, so that the moisture content of the pellets is regulated within the range of 8%-12%.

[0029] Working Principle: During the pelletizing process, pressure sensor 6 monitors the pressure changes of the green pellets as they roll within the disc in real time and transmits the pressure signal to control system 7. Control system 7 receives the signal and performs data analysis. If the analysis results indicate that the green pellets are not uniform in size, do not meet strength requirements, or that the raw material properties, humidity, or other conditions have changed, control system 7 will issue corresponding control commands to drive device 3, tilt adjustment device 4, and water supply device 5 to adjust the rotation speed, tilt angle, and water spray volume of the pelletizing disc, ensuring the production of green pellets with uniform size and qualified strength.
