The cuttings discharged outward are lifted from the ground and transported to the air by the screw conveyor 1. Under normal conditions, the cuttings fall from the first discharge port 11 into the first storage chamber 21 of the box 2, and enter the main cuttings dryer 61 through the box discharge port 23 of the first storage chamber 21 for cuttings separation and deoiling. When the main cuttings dryer 61 fails, the cuttings fall from the second discharge port 12 into the second storage chamber 22 of the box 2, and enter the standby cuttings dryer 62 through the box discharge port 23 of the second storage chamber 22 for cuttings separation and deoiling. After the cuttings are distributed and transferred to the standby cuttings dryer 62 for processing, the main cuttings dryer 61 can be shut down for maintenance. The present application arranges a first discharge port 11 and a second discharge port 12 on the screw conveyor 1, and correspondingly arranges a first storage chamber 21 and a second storage chamber 22 inside the box body 2, so that when a main cuttings dryer 61 fails, the cuttings can be promptly distributed and transferred to the second storage chamber 22 and the standby cuttings dryer 62 through the second discharge port 12, thereby solving the problem of cuttings recovery and processing when the cuttings dryer fails, achieving the effect of not stopping the machine due to a failure and continuously recovering and processing the cuttings, thereby ensuring the safety and progress of the drilling operation.
[0038] In addition, the first storage chamber 21 and the second storage chamber 22 of the box body 2 can also play the role of temporarily caching the drill cuttings, and can match and balance the processing speed of the cuttings dryer with the discharge flow of the cuttings, especially under the condition of large flow discharge of cuttings, it can prevent the cuttings from overflowing. Furthermore, for the extreme condition of large flow discharge of cuttings, the first discharge port 11 and the second discharge port 12 of the screw conveyor 1 can also be opened at the same time, and the cuttings enter the main cuttings dryer 61 and the standby cuttings dryer 62 for processing at the same time, ensuring that the cuttings do not overflow and pollute the environment.
[0039] Optionally, a valve is provided on the box discharge port 23, and the drill cuttings are temporarily stored and settled in the first storage chamber 21 or the second storage chamber 22 by opening and closing the valve.

Under normal conditions, the first discharge port 11 is open, the second discharge port 12 is closed, and the drill cuttings continue to be conveyed after passing through the second discharge port 12, and fall from the first discharge port 11 into the first storage chamber 21 of the box body 2, and then enter the main rock cuttings dryer 61 for processing; when the main rock cuttings dryer 61 fails, the first discharge port 11 is open, the second discharge port 12 is opened, and the drill cuttings fall from the second discharge port 12 into the second storage chamber 22 of the box body 2 in advance, and then enter the standby rock cuttings dryer 62 for processing. The second discharge port 12 is arranged forward of the first discharge port 11, and only one set of track door frame 13 and sliding door plate 14 can be used to realize the distribution and transfer of drill cuttings, simplifying the shell structure of the screw conveyor 1, increasing the reliability of the distribution and transfer of drill cuttings, and reducing the production and maintenance costs.
[0045] Optionally, a torque sensor is also provided on the driving end or auger of the screw conveyor 1, and the torque sensor can obtain the torque condition of the auger when conveying drill cuttings to prevent the screw conveyor 1 from overloading. When the torque exceeds a threshold value, a corresponding alarm signal is issued.
[0046] In some embodiments, the conveying direction of the screw conveyor 1 is inclined upward, the first discharge port 11 is higher than the second discharge port 12, the first discharge port 11 is located directly above the first storage cavity 21, and the second discharge port 12 is located directly above the second storage cavity 22. The track door frame 13 is welded to the outside of the shell at the second discharge port 12, the sliding door panel 14 is installed on the track door frame 13, and the telescopic rod is fixed to the outside of the shell and connected to the sliding door panel 14. The piston rod of the telescopic rod is extended and retracted, driving the sliding door panel 14 to slide to the corresponding position on the track door frame 13, so as to open or close the second discharge port 12.

[0048] Furthermore, a dispersing mesh plate 25 for screening and dispersing cuttings is provided on the top opening of the box 2. The surface of the dispersing mesh plate 25 is arranged with mesh holes of a certain aperture, which is equivalent to a screen, so as to disperse the sticky cuttings falling from the first discharge port 11 or the second discharge port 12 of the screw conveyor 1, and prevent the cuttings with too large particle size in the cuttings from entering the box 2 and the cuttings dryer.
[0049] In some embodiments, the box body 2 is located below the screw conveyor 1. A vertical partition 24 is disposed in the middle of the box body 2, and divides the internal cavity of the box body 2 into a first storage cavity 21 and a second storage cavity 22 that are arranged in parallel. The box body discharge port 23 is provided with a flange portion for connecting to a feed port of a cuttings dryer. A dispersion mesh plate 25 is fixed to the top opening edge of the box body 2, covering the first storage cavity 21 and the second storage cavity 22.
[0050] Specifically, the drill cuttings storage and distribution device further includes a handrail frame 3 arranged around the top opening edge of the box body 2 .
[0051] Specifically, the drill cuttings storage and distribution device further comprises an escalator 5 arranged on one side of the box body 2 , and the escalator 5 extends from the ground to the top of the box body 2 .

The handrail frame 3 can protect the personal safety of the operator and prevent accidental falls from a high altitude. In addition, the handrail frame 3 can also form an additional support for the screw conveyor 1.
[0053] Specifically, the drill cuttings storage and distribution device further comprises a leg frame 4 for elevating the box body 2, and the leg frame 4 comprises:
[0054] The main legs 41 are arranged at the bottom of the box body 2 and raise the box body 2;
[0055] The oblique connecting rod 42 connects two adjacent main supporting legs 41 in a cross manner.
[0056] In the present application, the drill cuttings falling into the box body 2 need to enter the cuttings dryer from the box body discharge port 23 at the bottom of the box body 2, and the cuttings dryer usually adopts top feeding. Therefore, the box body 2 should be elevated so that the cuttings dryer can be set below the box body 2. The height of the main legs 41 is set according to the feeding height of the cuttings dryer. Multiple main legs 41 support different positions at the bottom of the box body 2 respectively. The oblique connecting rod 42 connects two adjacent main legs 41 to increase the overall stability of the leg frame 4.
[0057] like Figure 1 As shown, a drill cuttings processing device includes the above-mentioned drill cuttings storage and distribution device, and a main cuttings dryer 61 and a spare cuttings dryer 62 arranged below the box body 2.
