AI Technical Summary

Technical Problem

Traditional drum-type rotary filter water treatment equipment has shortcomings in terms of filtration efficiency and continuity. The filter screen is prone to clogging, has a low degree of automation, is difficult to adapt to different water qualities and flow rates, has poor versatility, and is prone to equipment failure due to untimely operation.

Method used

The system employs a primary and secondary filtration mechanism combined with a motor-driven rotating mesh tube and hydraulic rod system to achieve automatic cleaning and secondary filtration. The filter screen is cleaned by brushes and scrapers, impurities are automatically discharged by the hydraulic rod, and the secondary filter screen plate is automatically closed and the collection tank is cleaned, thus improving the automation and filtration effect of the equipment.

Benefits of technology

It significantly improves the filtration efficiency and operational continuity of the equipment, reduces maintenance frequency, enhances the self-cleaning ability and stability of the equipment, and adapts to the processing capacity of different water qualities and flow rates.

Abstract

This invention relates to the field of water treatment equipment technology, specifically disclosing a drum-shaped rotary filter water treatment device, including an inlet hood with a diversion pipe fixedly connected to its bottom; a primary filtration mechanism fixedly connected to the bottom of the diversion pipe; and a secondary filtration mechanism fixedly connected to the bottom of the primary filtration mechanism. When the rotating screen starts rotating with the motor, it drives the mounting pipe to rotate synchronously via a connecting rod. The rotation of the mounting pipe then drives the scraper on its inner surface to rotate, causing the outer end of the scraper to rub and rotate along the outer surface of the filter screen, cleaning the outer surface of the filter screen. This significantly reduces the possibility of impurities in the wastewater clogging the outer surface of the filter screen. Simultaneously, combined with the synchronous operation of the mounting strip, this ensures effective wastewater filtration while also significantly extending the filtration time of the device, thereby greatly improving its practicality.
