Description

Technical Field

[0001] The invention belongs to the technical field of solid-liquid separation equipment, and in particular relates to a full-automatic intelligent vertical disc filter control system. Background Art

[0002] As an important and efficient solid-liquid separation device in modern industry, the disc filter, with its unique design and superior separation performance, is widely used in a variety of industries, including mining (especially metal concentrate dehydration), chemical production, environmental engineering, and food processing. Its core structure consists of a precise combination of multiple vertically arranged rotating filter discs. Through a vacuum adsorption or pressure drive mechanism, combined with high-performance filter cloth, it effectively separates solid particles from liquid in suspensions, demonstrating significant advantages in large processing capacity and high separation efficiency.

[0003] However, despite significant technological advancements, disc filters still face numerous technical bottlenecks and challenges in practical application. First, the equipment's startup and shutdown procedures are complex, involving coordinated operations across multiple processes and requiring close collaboration between on-site technicians and back-office scheduling teams. This not only increases labor costs but also increases operational risks. Second, the filter cloth, a key consumable, is susceptible to damage and clogging, hindering stable operation. Failure to promptly replace damaged or damaged cloths directly degrades equipment performance, leading to a series of chain reactions such as abnormally high vacuum pump current, a significant decrease in equipment production capacity, and an increase in filter cake liquid attachment. Furthermore, when processing highly viscous or fine-particle materials, filter cloth clogging is a frequent problem. If blockages are not promptly cleared, filtrate flow is blocked, reducing equipment performance. Frequent equipment shutdowns for cleaning can severely impact production continuity and efficiency. Furthermore, disc filters are extremely sensitive to subtle changes in material properties. Existing disc filters lack sufficient flexibility in dynamically adjusting parameters (such as feed rate), making them difficult to adapt to complex and changing operating conditions, thus limiting their potential for wider application in a wide range of industrial scenarios.

[0004] As mentioned above, how to provide a fully automatic intelligent vertical disc filter control system that can achieve full automatic control, monitor the working status of each component in the vertical disc filter in real time and make adjustments and early warnings has become an urgent problem to be solved.
