Description

Drilling waste separation device

Technical Field

The utility model relates to the technical field of drilling waste treatment, in particular to a drilling waste separation device.

Background Art

Drilling waste is waste generated during the oil and gas extraction process, and the direct discharge of this mixture of mud and oil causes irreversible pollution to the soil environment. In order to avoid reducing this impact, the oil and water in the drilling waste are often removed by centrifugal separation. However, it is currently found during centrifugal separation that some mud and sand will adhere to the inner wall of the separation tank during centrifugal separation, so frequent cleaning is required, and cleaning requires downtime maintenance, which will cause stagnation in waste treatment. Or, during the centrifugal process, cleaning is performed by spraying water. Although this cleaning method can achieve the purpose of cleaning, the wastewater generated by cleaning needs additional treatment, which increases the treatment cost.

Utility Model Content

The utility model provides a drilling waste separation device to solve the deficiencies of the above-mentioned prior art, can clean up the attachments in time, thereby improving the processing efficiency, reducing the processing cost, and has strong practicality.

In order to achieve the purpose of this utility model, the following technologies are proposed:

A drilling waste separation device includes a tank body, a plurality of constraint rings are arranged inside the tank body, a plurality of holes are opened on the constraint rings, the lower end of the tank body is a funnel-shaped structure, and the lower end of the tank body is a small end, and the lower end of the tank body is connected to a discharge pipe, and this structural design facilitates the discharge of liquid. A motor is installed at the lower end of the discharge pipe, and a rotating shaft is connected to the output shaft of the motor through a coupling, and this connection method can avoid affecting the output shaft of the motor. A centrifugal tank is arranged at the upper end of the rotating shaft, and a plurality of discharge holes are opened on the centrifugal tank. A plurality of scrapers are arranged on the outer wall of the centrifugal tank, and the scrapers are located between two adjacent constraint rings, and the outer ends of the scrapers are tangent to the inner wall of the tank body, and the discharge pipe is connected to the discharge pipe. The constraint ring constrains the rotating centrifugal tank, thereby ensuring the stability of the rotation of the centrifugal tank. The setting of the scraper can scrape off the attachments attached to the inner wall of the tank body, so as to complete the cleaning operation of the inner wall of the tank body without stopping the machine.

The scrapers 34 are located between two adjacent restraining rings 26, and the outer ends of the scrapers 34 are tangent to the inner wall of the tank body 2, and the feed pipe 21 is connected with a discharge pipe 22. A guide column 27 is provided at the lower end of the feed tube 21, and an inclined surface is provided at the upper end of the guide column 27. The axial direction of the discharge tube 22 is perpendicular to the axial direction of the feed tube 21, and the inclined surface is inclined toward the discharge tube 22. A plurality of inclined support plates 23 are provided at the lower end of the tank body 2, and a placement plate 24 is provided at the other end of the inclined support plates 23, and the centrifugal tank 33 is placed on the placement plate 24. A rotating ring 31 is installed at the lower end of the rotating shaft 30, and a plurality of inclined scrapers 32 are provided on the outer periphery of the rotating ring 31, and the outer wall of the inclined scraper 32 is tangent to the inner wall of the lower end of the tank body 2.

When one centrifugal separation is completed, the rotating motor 15 is started, and the gear 14 is rotated under the drive of the rotating motor 15.
