Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a mud and sand separation device for oil drilling. Background Art

[0002] During oil drilling operations, a large amount of mud and sand will be generated. In order to utilize these resources more effectively and reduce waste, users will separate the fine sand from the mud and sand. To achieve this goal, it is necessary to rely on special mud and sand separation devices. These devices can effectively perform the separation of fine sand and ensure the rational use of resources.

[0003] However, traditional sediment separation devices are often not ideal in sediment separation effects, especially in the separation of fine sand. These devices are often unable to fully separate fine sand from impurities and coarse sand, resulting in the fine sand being mixed with other impurities and coarse sand components, which greatly reduces the recovery rate of fine sand.

[0004] Therefore, in view of the fact that the above-mentioned sediment separation device is often not ideal in sediment separation effect, resulting in the situation that other impurities and coarse sand components are mixed in the fine sand, a sediment separation device for oil drilling can be designed to improve the sediment separation efficiency through a gear transmission structure and a filtering structure, thereby increasing the recovery rate of fine sand.

The No. 1 gear 806 is meshedly connected to the No. 2 gear 807. The rotating motor 801 is the power source of the entire rotating assembly. It converts electrical energy into mechanical energy to drive the rotating shaft 802 to rotate. The rotating shaft 802 drives the No. 1 gear 806 to rotate under the drive of the motor. The function of the limiting column 803 is to support the rotation of the rotating shaft 802 and limit the axial movement of the rotating shaft 802 during the rotation process to ensure the stability of the rotating shaft 802. The limiting rod 804 is used to support the rotation of the supporting shaft 805 and limit the support shaft 805 in During the axial movement of the rotation, a bearing-like rotating mechanism is designed between the limit rod 804 and the support shaft 805 to reduce friction and wear and improve the rotation efficiency.

They are connected by meshing to realize the power transmission between the rotating shaft 802 and the support shaft 805. By designing different numbers of gear teeth, different speed ratios and transmission efficiencies can be achieved to meet different mud and sand separation requirements. The centrifugal assembly includes a feed frame 901, a limit ring 902, and a centrifugal barrel 903; the feed frame 901 is installed in the separation box 4, and the feed frame A limiting ring 902 is installed at the lower end of 901, and the upper end of a centrifugal barrel 903 for separating mud and sand is rotatably connected to the limiting ring 902, and the lower end of the centrifugal barrel 903 is fixedly connected to the support shaft 805.

The centrifugal barrel 903 is shaped like a hollow cylindrical structure, and the rotation function is realized by the support shaft 805. When the centrifugal barrel 903 rotates, the mud and sand therein will be affected by the centrifugal force and move outward along the barrel wall to achieve the purpose of separating coarse sand and fine sand. The material of the centrifugal barrel 903 can be selected from corrosion-resistant and wear-resistant materials.

[0029] During the working process, the staff first uses the universal wheel 2 of the device to easily move it to the designated working area, and then accurately adds the mixture of silt and water into the filter box 3 through the feeding hopper 5. Next, after the silt is carefully screened by the filter screen 704, the large impurities therein are effectively filtered out. The filtered silt, under the guidance of the inclined block 705, smoothly enters the feed pipe and flows smoothly into the centrifugal cylinder 903 through the feed pipe.

[0030] At this time, the rotating motor 801 starts to work, driving the rotating shaft 802 to rotate, and then driving the No. 1 gear 806 to rotate. Through the precise meshing action between the gears, the No. 2 gear 807 and the supporting shaft 805 also rotate synchronously, thereby driving the centrifugal cylinder 903 to rotate rapidly. In this process, the sediment in the centrifugal cylinder 903 is naturally separated from the coarse sand and the fine sand under the action of centrifugal force;

[0031] After the separation is completed, the staff only needs to collect and receive the pure fine sand from the discharge pipe 6. If the filter screen 704 needs to be replaced, the operation is also simple. Just gently pull the handle to pull the filter plate 701 out of the filter box 3, and then easily replace the filter screen 704 on the filter plate 701.

[0032] Through the above steps, through the joint operation of the filtering component, the rotating component and the centrifugal component, not only can the large particles of impurities be effectively removed, laying a solid foundation for the subsequent centrifugal operation, but also the silt can be finely separated in the centrifugal cylinder 903 through the rotating force. In this process, coarse sand and fine sand can be clearly distinguished, thereby achieving efficient recovery of fine sand. This joint operation mode of filtering, rotating and centrifugal components not only significantly improves the working efficiency of silt separation, but also ensures the high quality of the separation results, and solves the problem that the silt separation device is often not ideal in the silt separation effect, resulting in other impurities and coarse sand components mixed in the fine sand.
