A disc filter sector fixing device

By designing a fan-shaped plate fixing device, the filter cloth is tightened radially and circumferentially using arc-shaped guide rails and a clamping frame. This solves the problem of easy wrinkling and damage to the filter cloth, achieves the flatness of the filter cloth and the stability of the fan-shaped plate, extends the service life of the filter cloth, and improves the reliability of equipment operation.

AI Technical Summary

Technical Problem

The filter cloth of disc filters is prone to wrinkles and damage, resulting in a short service life. In addition, the sector plates lack a reliable fixing mechanism, making them easy to tip over, which affects the operating efficiency and safety of the equipment.

Method used

A fan-shaped plate fixing device is designed, including an arc-shaped guide rail, a tie rod, a clamping frame, and a fan-shaped plate fixing ring. The arc-shaped guide rail and the clamping frame clamp the filter cloth in the radial and circumferential directions to ensure that the filter cloth is tightly attached to the fan-shaped plate, and the fan-shaped plate fixing ring stabilizes the fan-shaped plate to prevent swaying and tilting.

Benefits of technology

It extends the service life of the filter cloth, prevents the filter cloth from being torn by the scraper, ensures the stable installation of the sector plate, and improves the reliability and efficiency of equipment operation.
