Description

Technical Field

[0001] This utility model relates to the field of rock cuttings cleaning devices, and more particularly to a device that facilitates the cleaning of rock cuttings. Background Technology

[0002] Rock cuttings generated during drilling are important information for understanding the formation and are a crucial basis for discovering and evaluating oil and gas reservoirs. During drilling, it is necessary to analyze the sandstone in the rock cuttings to obtain accurate geological information, promptly determine the location and depth of oil and gas reservoirs, and facilitate adjustments to the drilling trajectory. When drilling cuttings are brought up from the well by drilling mud, they contain a large amount of mud, so they must be cleaned to obtain clean cuttings before identification.

[0003] A search revealed a Chinese patent publication number (CN206793887U) that discloses a device for cleaning rock debris. The device includes feeding a mixture of collected mud and rock debris into a rotary screen via a hopper, turning on an explosion-proof motor to rotate the screen at high speed, and cleaning and drying the rock debris by adding clean water while rotating. Wastewater is discharged into a mud tank through a drainage pipe. This process is repeated 3-5 times to complete the sand washing. After washing, the material handling door of the sand washing chamber and the sliding window of the baffle are opened to remove the washed rock debris from the rotary screen and place it on a drying platform.

[0004] In actual use, the internal bottom surface of the rotary screen used for rotary cleaning and drying is usually a flat structure. After the rock debris mixed with mud is placed into the rotary screen, the rock debris will accumulate on the internal bottom surface of the rotary screen. At this time, the mud is easy to accumulate on the internal flat surface of the rotary screen and cannot flow out quickly along the internal bottom surface of the rotary screen. During the rotary cleaning process, due to the obstruction of the accumulated rock debris and the limitation of the bottom flat surface, the cleaning liquid cannot be discharged quickly, which affects the cleaning efficiency. Therefore, a device that facilitates the cleaning of rock debris is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a device for easy cleaning of rock cuttings, which aims to improve the problem in the prior art where mud and cleaning fluid cannot be quickly discharged when rock cuttings accumulate on the bottom surface of the rotary screen after entering it.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 This utility model provides an embodiment of a device for facilitating the cleaning of rock debris, comprising a cleaning cylinder 1, a feed hopper 2 fixedly connected to the upper surface of the cleaning cylinder 1, a movable filter cylinder 7 being placed into the cleaning cylinder 1 through the feed hopper 2, a drainage channel 3 being provided on the bottom surface of the cleaning cylinder 1, through which wastewater inside the cleaning cylinder 1 can be discharged, an isolation cavity 4 being provided in the bottom inner wall of the cleaning cylinder 1, a motor 5 being fixedly connected to the bottom surface of the isolation cavity 4, the isolation cavity 4 protecting the outside of the motor 5 from water contact and damage to the motor 5, and a rotating filter cylinder 6 being fixedly connected to the top output end of the motor 5, which can drive the rotating filter cylinder 6 to rotate when the motor 5 is started.

[0034] Reference Figures 2-4The bottom of the rotating filter cartridge 6 is provided with a support unit, which includes a rotating shaft 61. The rotating shaft 61 is rotatably connected to the bottom surface of the rotating filter cartridge 6, and a rotating frame 62 is fixedly connected to the bottom surface of the rotating shaft 61. The rotating frame 62 can rotate horizontally around the rotating shaft 61. A ball bearing 63 is rotatably connected inside the rotating frame 62. The ball bearing 63 can rotate back and forth inside the rotating frame 62. With the cooperation of the rotating frame 62 and the rotating shaft 61, the ball bearing 63 can rotate at an easy angle in the horizontal direction. When the rotating filter cartridge 6 rotates, it can drive the ball bearing 63 to rotate synchronously, converting the static friction between the filter cartridge 6 and the bottom surface of the cleaning cartridge 1 into rolling friction. To reduce frictional resistance when the rotating filter cylinder 6 rotates, the bottom end of the ball bearing 63 fits against the inner bottom surface of the cleaning cylinder 1. With the cooperation of the set support unit, the bottom of the rotating filter cylinder 6 can be limited and supported, so that the rotating filter cylinder 6 remains stable during rotation and avoids tilting or deviation during the rotation of the moving filter cylinder 7, which could lead to breakage or damage at the connection with the motor 5. The moving filter cylinder 7 is inserted into the rotating filter cylinder 6. The moving filter cylinder 7 can be pulled out from the top of the rotating filter cylinder 6. The size of the moving filter cylinder 7 is adapted to the internal size of the feed hopper 2, and the moving filter cylinder 7 can move up and down through the feed hopper 2.

[0035] Both the rotating filter cylinder 6 and the moving filter cylinder 7 have filter holes on their outer wall surfaces. The cleaning fluid and mud entering the rotating filter cylinder 6 and the moving filter cylinder 7 can be discharged through the filter holes. The bottom surface of the moving filter cylinder 7 is fixedly connected to a truncated cone 8. When rock cuttings enter the moving filter cylinder 7, they will accumulate on the truncated cone 8 along its inclined surface. At this time, the mud can flow along the inclined surface of the truncated cone 8 and then quickly flow out of the moving filter cylinder 7, avoiding the mud from accumulating on the bottom surface of the moving filter cylinder 7 and not being able to flow out quickly, thus affecting the cleaning efficiency. When water enters the moving filter cylinder 7 to wash the rock cuttings, it can also be quickly discharged along the inclined surface of the truncated cone 8, which can improve the cleaning efficiency.

[0036] The bottom of the movable filter cylinder 7 is equipped with a limiting unit, which includes a limiting rod 91. The limiting rod 91 is fixedly connected to the inner bottom surface of the rotating filter cylinder 6. When the rotating filter cylinder 6 rotates, it can drive the limiting rod 91 to move synchronously. The bottom surface of the movable filter cylinder 7 has an arc-shaped groove 92, the size of which is adapted to the size of the limiting rod 91. The limiting rod 91 is slidably connected to the inside of the arc-shaped groove 92. When the limiting rod 91 is directly inserted into the inside of the arc-shaped groove 92, it can slide inside the arc-shaped groove 92. At this time, the motor 5 starts and drives the rotating filter cylinder 6 to move. During rotation, the limiting rod 91 can be driven to rotate inside the arc-shaped groove 92. When the limiting rod 91 moves to fit against the inner wall of the arc-shaped groove 92, it can drive the moving filter cylinder 7 to rotate synchronously, so that the moving filter cylinder 7 can rotate synchronously with the rotating filter cylinder 6. The rock debris entering the moving filter cylinder 7 can be quickly cleaned and dried by rotation. A rubber pad 93 is fixedly connected to the inner wall surface of the arc-shaped groove 92. The rubber pad 93 can prevent the limiting rod 91 from contacting and colliding with the inner wall of the arc-shaped groove 92, and prevent the limiting rod 91 from being damaged by impact.

[0037] When the movable filter cartridge 7 is inserted into the rotating filter cartridge 6, if the limiting rod 91 is not directly inserted into the arc groove 92, the movable filter cartridge 7 will rest on the limiting rod 91. As the rotating filter cartridge 6 drives the limiting rod 91 to rotate, the arc groove 92 will quickly align with the limiting rod 91, thereby completing the insertion. This allows the movable filter cartridge 7 and the rotating filter cartridge 6 to be connected quickly, reducing the difficulty of operation.

[0038] Reference Figures 5-6 The upper surface of the movable filter cartridge 7 is provided with an annular groove 10. A handle 11 is rotatably connected inside the annular groove 10. The handle 11 can be rotated from inside the annular groove 10 to a vertical position, so that the operator can easily lift the movable filter cartridge 7 through the handle 11 to complete the disassembly. A protective sleeve 12 is fixedly connected to the left end of the handle 11. The protective sleeve 12 can increase the contact area between the handle 11 and the operator's palm, making it easier for the operator to operate the handle 11. A rectangular groove 13 is provided on the left inner wall of the annular groove 10. The protective sleeve 12 is located inside the rectangular groove 13 and can be stored inside the rectangular groove 13. A drainage groove 14 is provided on the left inner wall surface of the rectangular groove 13. The drainage groove 14 passes through the movable filter cartridge 7. The right end of the drainage groove 14 is connected to the inside of the rectangular groove 13. Water that enters the annular groove 10 during the cleaning process can be discharged through the drainage groove 14.

[0039] Working principle: Rock cuttings are placed into the movable filter cylinder 7, and then the movable filter cylinder 7 is inserted into the rotating filter cylinder 6 through the feed hopper 2 to complete the installation. At this time, the motor 5 can be started to drive the rotating filter cylinder 6 and the limiting rod 91 to rotate, so that the limiting rod 91 quickly aligns with the arc groove 92. At this time, the movable filter cylinder 7 will move downward, so that the limiting rod 91 is inserted into the arc groove 92. Subsequently, the rotating limiting rod 91 can drive the movable filter cylinder 7 to rotate synchronously with the rotating filter cylinder 6. The rock cuttings entering the movable filter cylinder 7 are quickly cleaned and dried by rotation. When the rock cuttings mixed with mud are removed... When the mud enters the mobile filter cylinder 7, it can be discharged through the filter holes of the mobile filter cylinder 7 and the rotating filter cylinder 6 along the inclined surface of the cone 8. The mud accumulates on the bottom surface of the inside of the mobile filter cylinder 7 and cannot flow out quickly, affecting the cleaning efficiency. Then, clean water can be introduced into the washing cylinder 1 from the feed hopper 2 to clean the rock chips. The waste liquid after cleaning can be discharged quickly along the inclined surface of the cone 8. After cleaning, the staff can put their hands into the washing cylinder 1 through the feed hopper 2, lift the mobile filter cylinder 7 out through the protective sleeve 12 and the handle 11, take out the washed rock chips in the mobile filter cylinder 7, and send them to the drying platform.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
