AI Technical Summary

Technical Problem

Existing hydrocyclone desanders and desilters have poor separation performance and efficiency under high-viscosity drilling fluid conditions, making them difficult to adapt to complex working conditions. Their drive units lack stability and durability, and their capacity to process drilling fluids of different viscosities and densities is limited.

Method used

An integrated hydraulic mechanical device for sand and mud removal is adopted. Through belt drive combined with a hydrocyclone separator, and with the design of an adjustable mounting plate and adjusting screw, combined with deep groove ball bearings and auxiliary support mechanism, the conical tube can be stably rotated, and further screening is carried out in conjunction with a vibrating screen mechanism.

Benefits of technology

It improves the separation effect and adaptability to variable flow conditions, reduces the requirements for feed pressure, enhances the stability of the transmission system and the service life of the equipment, improves the solid-liquid separation efficiency and the recovery rate of solid particles, and meets the needs of diverse application scenarios.
