Description

Technical Field

[0001] The utility model relates to the technical field of drilling waste treatment, in particular to a drilling waste separation device. Background Art

[0002] Drilling waste is waste generated during the oil and gas extraction process. Directly discharging this mixture of mud, sand, and oil can cause irreversible soil pollution. To mitigate this impact, centrifugal separation is often used to remove the oil and water from drilling waste.

[0003] Chinese Patent No. 202420516970.6 discloses a drilling waste separation device, comprising a tank body, internally provided with multiple restraining rings each having multiple holes. The lower end of the tank body is funnel-shaped, with a small end. A discharge pipe is connected to the lower end of the tank body, facilitating liquid discharge. A motor is mounted at the lower end of the discharge pipe, and the motor's output shaft is connected to a rotating shaft via a coupling. This connection prevents any impact on the motor's output shaft. A centrifugal tank is located at the upper end of the rotating shaft, with multiple discharge holes formed in the centrifugal tank. Multiple scrapers are provided on the outer wall of the centrifugal tank, positioned between adjacent restraining rings. The outer ends of the scrapers are tangential to the inner wall of the tank body. The discharge pipe is connected to the discharge pipe. The restraining rings constrain the rotating centrifugal tank, ensuring stable rotation. The scrapers can scrape off debris adhering to the inner wall of the tank body, allowing the tank body to be cleaned without shutting down.

[0004] However, when the above-mentioned separation device is in use, although the tank body can be rotated to facilitate the pouring out of the sediment obtained by centrifugation from the centrifugal tank, when the centrifugal tank needs to be removed from the tank body for maintenance, cleaning or replacement, it is relatively inconvenient because the centrifugal tank is relatively heavy. Therefore, a drilling waste separation device is proposed. Utility Model Content
