AI Technical Summary

Technical Problem

Existing non-metallic chain-plate scrapers suffer from insufficient chain flexibility and scraper rigidity during long-distance operation, causing the scraper plates to easily vibrate up and down or wobble, resulting in uneven scraping and localized residual sludge.

Method used

The design employs a support structure and reciprocating drive components. The support structure provides multi-point support and a stabilizing frame to enhance rigidity. Combined with the reciprocating drive components, it drives the side scraper to move back and forth along the track rod, achieving efficient cleaning of the pool bottom and pool walls.

Benefits of technology

It effectively reduces the swaying and shaking of the scraper blades, ensures stable operation of the scraper blades, avoids local sludge residue, improves cleaning effect, and saves space and energy consumption.

Abstract

This utility model discloses a non-metallic chain-plate type sludge scraper, including a sludge scraping tank, a positioning shaft, a sprocket, a drive motor, and sludge scrapers. A discharge port is located at the bottom of the sludge scraping tank near one side. The positioning shaft is rotatably connected to the sludge scraping tank, and the drive motor is fixedly connected to the side of the sludge scraping tank. The output shaft of the drive motor is fixedly connected to one end of a set of positioning shafts extending outside the sludge scraping tank. This utility model features a support structure movably connected to the positioning shaft, and a stabilizing frame movably connected to the inner side of the sludge scrapers. This provides multi-point support for the dispersed sludge scrapers, effectively distributing the chain load and reducing operational swaying, shaking, and vertical vibration. This not only extends the equipment's lifespan but also ensures stable sludge scraping, preventing localized sludge residue. It solves the problem in existing sludge scrapers where insufficient spacing or rigidity of the non-metallic chain during long-distance operation leads to vertical vibration or swaying of the sludge scrapers, resulting in uneven sludge scraping and localized sludge residue.
