Based on the embodiments of the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the scope of the present application.

[0026] Embodiment:

[0027] The embodiment provides a stratum rock debris automatic processing device, as shown in Figure 1 and Figure 2 , comprising: a water flow pipeline 1 serving as an entrance of the rock debris into a cleaning system, connected to a discharge outlet of a drilling device, ensuring that the rock debris can smoothly flow into a subsequent processing unit; a spiral pipe 2, one end of the spiral pipe 2 being threadedly connected with the water flow pipeline 1, a height difference of the spiral pipe 2 being set as 150 mm, so as to ensure that the rock debris can be sufficiently turned over when passing through to realize overall cleaning. The spiral pitch of the spiral pipe is 620 mm, and a stainless steel material is adopted, which not only enhances durability but also reduces the possibility of internal corrosion. A straight pipeline 3, the straight pipeline 3 being threadedly connected with the other end of the spiral pipe 2, a U-shaped groove window 4 being arranged above the straight pipeline 3; a foam suction pipe sealing seat 5, the foam suction pipe sealing seat 5 covering the U-shaped groove window 4 of the straight pipeline and being welded and sealed with the straight pipeline 3, so as to ensure that a negative pressure environment in the system is not damaged. A foam suction pipe opening 6 overlaps with the U-shaped groove window 4, for suction of foam; an adjusting valve 7, arranged at the end of the straight pipeline 3; the adjusting valve 7 comprising an adjusting valve seat 8 and an adjusting valve piece 9; the adjusting valve seat 8 being welded and fixed with the straight pipeline 3, and the position of the adjusting valve piece 9 on the adjusting valve seat 8 being adjustable, the adjusting valve seat being welded and fixed with the straight pipeline, and the position of the adjusting valve piece being adjustable according to needs, so as to control water flow speed and direction and promote foam formation; a foam storage tank 10, connected with the foam suction pipe sealing seat 5 through a pipeline, for collecting and storing foam and other light impurities separated from the rock debris cleaning process; a liquid level sensor 12 being arranged in the foam storage tank, for real-time monitoring of internal liquid level change, to prevent overflow due to overfilling.

In order to prevent liquid backflow, a one-way valve (14) is arranged on the connecting pipeline between the air extractor and the foam storage tank.

[0028] Working principle:

[0029] When the drilling fluid containing cuttings is discharged from the drilling equipment, it first enters the spiral pipe 2 through the flow pipe 1. Due to the height difference and special design of the spiral pipe, the cuttings will be turned over during the flow process, thereby being fully washed. Subsequently, the cuttings and water mixture flows into the straight pipe 3, during which the action of the regulating valve 7 causes the water flow to form a backflow vortex at the end, promoting the generation of foam. These foams, together with light impurities, are sucked into the suction pipe port 6 and transmitted to the foam storage tank 10 through the suction pipe sealing seat 5. The negative pressure condition provided by the air extractor 11 ensures the smooth progress of the process. The liquid level sensor 12 in the foam storage tank monitors the internal conditions to ensure that overflow does not occur. Finally, regularly opening the drain valve 13 can clean the sediment and waste liquid stored at the bottom of the foam storage tank, maintaining the normal operation of the entire system.

[0030] The embodiment provides a method for efficiently, reliably and easily maintaining the turning and cleaning of stratum cuttings and automatically removing floating foam, which is suitable for the cuttings treatment requirements in various geological drilling projects.
