AI Technical Summary
During the coal blending process in thermal power plants, the uneven weight of coal due to differences in coal quality makes it impossible to accurately control the amount of coal input, which can easily lead to overflow and coal sticking, affecting equipment safety and operating efficiency.
An automatic plow lifting device was designed. By setting up a movable bin and a limiting structure in the coal bunker, the opening and closing of the conveying device is automatically controlled by the weight of the coal, ensuring that the coal bunker automatically stops conveying when fully loaded and automatically resumes conveying function when unloaded.
It enables automatic control of coal input based on coal weight, preventing overflow and coal sticking, improving the accuracy of coal conveying and equipment safety, and simplifying the operation process.
