Technical Problem

一方面，钻井液中的岩屑粒径分布广泛，从毫米级的粗颗粒到微米级的细颗粒混杂其中，单一的分离方式难以实现彻底分离

Benefits of technology

[0013]This application utilizes an inclined rotating drum to achieve centrifugal filtration, which uses centrifugal force to initially separate rock cuttings from drilling fluid. The inclined structure facilitates the aggregation of rock cuttings at one end. Flocculant is added above the conical baffle and, in conjunction with a stirring mechanism, coagulates fine particles, improving subsequent filtration efficiency. The filter screen further traps particles, a scraping mechanism prevents clogging, and a drain pipe facilitates the collection of purified liquid. The overall device achieves a multi-stage separation process of "centrifugal filtration—flocculation reaction—filter filtration," improving solid-liquid separation efficiency and quality, and its compact structure adapts to the needs of drilling site operations.
