[0037] Installation component: This component is used to firmly connect the input end of the slag suction and hole cleaning pump 1 and the top end of the suction steel pipe 2. Specifically, the installation component includes a first connecting flange 3 fixedly arranged at the input end of the slag suction and hole cleaning pump 1, and a second connecting flange 4 fixedly arranged at the top end of the suction steel pipe 2 and used in conjunction with the first connecting flange 3. The first connecting flange 3 and the second connecting flange 4 are fixed by a plurality of bolts 5 and nuts 6 used in conjunction with each other to ensure the stability of the connection;

[0038] Dry-wet separation component: This component is arranged outside the suction and cleaning pump 1, and is used to separate the mud containing drilling debris into dry and wet parts. The dry-wet separation component mainly includes a dry-wet separator 10, model SDFLJ-TS-180, whose input end is connected with the L-shaped conveying pipe 7 through a rubber hose 11. The dry slag in the dry-wet separator 10 is discharged from the dry slag discharge port 12, which is convenient for unified collection and treatment. The separated mud is connected through the connecting pipe 13 between the drainage port of the dry-wet separator 10 and the mud pool, and flows back to the mud pool to realize the recycling of the mud;

[0039] Flow regulation and control: A flow control valve 8 is provided on the L-shaped conveying pipe 7 to adjust the flow of the mud to meet different slag cleaning requirements. At the same time, in order to monitor the flow of the mud in real time, a flow meter 9 is also provided on the L-shaped conveying pipe 7 to provide accurate data support for the operator.

[0040] Embodiment 2

[0041] Improvements based on Example 1:

[0042] Please refer to Figure 3 In order to facilitate the hanging and movement of the entire device, a hook ring 14 used in conjunction with a crane hook is symmetrically fixed on the top of the slag suction and hole cleaning pump 1. Through equipment such as a crane, the operator can easily hang the slag suction and hole cleaning pump 1 and the suction steel pipe 2 as a whole for movement and positioning.

[0043] During the specific operation, the operator first extends the suction steel pipe 2 into the borehole, and then starts the suction and hole cleaning pump 1, and extracts the mud containing drilling cuttings through the suction steel pipe 2. The mud is introduced into the dry-wet separator 10 through the L-shaped conveying pipe 7 and the rubber hose 11 for dry-wet separation. The separated dry slag is discharged from the dry slag discharge port 12, and the mud is returned to the mud pool through the connecting pipe 13. During the whole process, the operator can adjust the flow rate of the mud through the flow control valve 8 and monitor the flow rate of the mud in real time through the flow meter 9. When it is necessary to move or adjust the position of the device, the operator can use equipment such as a crane to suspend the suction and hole cleaning pump 1 and the suction steel pipe 2 as a whole through the hook ring 14 for movement.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the slag suction and hole cleaning pump 1 and the dry-wet separator 10 are commonplace, and are conventional means or common knowledge, and will not be elaborated here.
