Product Introduction:

Shenghe’s plate-type ladder screen is a kind of water treatment equipment that can continuously and automatically intercept and remove all kinds of debris in the flow of water. It can be widely used in urban sewage treatment, tap water industry, and also can be used as the front screening equipment in the wastewater treatment process of textile, food processing and other industries.

Structure and Working Principle:

The plate-type stepped bar screen is a rotary cleaning device assembled from stainless steel trash racks. Driven by a gearbox, the trash racks rotate countercurrently to continuously remove fine floating debris from wastewater. When the rotating bars reach the discharge port, most solid particles settle by gravity while others are swept away by the cleaning brushes, effectively preventing contaminants from entering the system. This design ensures optimal collection and transportation of bar screenings while maintaining water flow area and capacity that fully meet design specifications.

Main Features:

This equipment boasts high automation, superior separation efficiency, low power consumption, noise-free operation, and excellent corrosion resistance. It ensures continuous stable operation without human supervision. Equipped with overload safety protection devices, it triggers audible-visual alarms and automatic shutdown mechanisms during malfunctions, effectively preventing overloading. Users can freely adjust operational intervals to achieve periodic cycles, while the system automatically controls operations based on liquid level differences before and after the screen, complemented by manual control functions for maintenance convenience. The device’s rational structural design enables enhanced self-cleaning capabilities, eliminating clogging issues and requiring minimal daily maintenance.

Roughening and Deformation Issues of Toothed Rakes:

Manifestations and Analysis: During flood seasons, excessive and concentrated debris overload individual toothed rakes, causing shaft deformation and subsequent malfunctions. As a critical moving component in mechanical grates, the toothed rake shaft serves dual functions: supporting chains to prevent derailment and facilitating debris removal. The middle section of this shaft constitutes a vulnerable link in the system. Common issues such as chain plate twisting and chain disengagement primarily stem from deformation of the toothed rake tube.

Therefore, sufficient strength and rigidity must be ensured. Design considerations: The toothed rake shaft material should have adequate diameter and strength. For mechanical grates with spans under 6 meters, the shaft should be verified according to 10000N.m concentrated load requirements, ensuring deflection does not exceed 1/250. For larger-scale mechanical grates, multiple traction chains may be employed to optimize force distribution on the toothed rake, or localized reinforcement at the shaft’s midsection can be implemented to create a variable-section load-bearing component.
