AI Technical Summary

Technical Problem

In traditional water-based drilling waste solid-liquid separation devices, a large amount of waste often accumulates on the surface of the filter screen, requiring frequent manual cleaning and affecting operational efficiency.

Method used

The device employs a self-cleaning filter-type dynamic filtration solid-liquid separation system for water-based drilling waste. It includes a gradient slope, a coarse-pore filter, a fine-pore filter, and an activated carbon filter. Combined with an electric push rod and a hydraulic cylinder, it achieves automatic cleaning of impurities from the filter, reducing manual intervention.

Benefits of technology

It achieves automated cleaning of filter screen impurities, improves work efficiency, reduces manpower consumption, and eliminates the need for additional water pump equipment, making it more energy-efficient.
