The end of the mud pipe can be fixed in position by being fixed to the slag-liquid kinetic energy attenuation tank 1 or any other suitable means. The lower part of the slag-liquid kinetic energy attenuation box 1 is connected with the upper part of the sediment box 3 into a whole, and the positions of a slurry outlet of the slag-liquid kinetic energy attenuation box 1 correspond to the positions of a slurry inlet of the sediment box 3. Preferably, the inlet end of the mud pipe 5 and the mud outlet pipe of the drilling machine can be butted through a quick joint 6, so that the mud pipe can be quickly disassembled and assembled on the premise of ensuring the sealing requirement. Further, other conventional connection methods between the inlet end of the mud pipe 5 and the mud pipe of the drilling machine can be selected according to actual conditions, and the protection scope of the invention is also included.
Furthermore, a grid plate 2 is arranged between the slag-liquid kinetic energy attenuation box 1 and the sediment box 3, and the drilling slag liquid blocked by the slag-liquid kinetic energy attenuation box 1 flows back to the grid plate 2 below the slag-liquid kinetic energy attenuation box 1, so that the functions of further attenuating the kinetic energy of the drilling slag liquid, shunting and screening and filtering large drilling slag are achieved. The grid plate is arranged between the slag-liquid kinetic energy attenuation box and the sediment box, and the grid plate can play a role in screening and filtering large drilling slag between the slag-liquid kinetic energy attenuation box and the sediment box. Preferably, the grating 2 is horizontally fixed in the slag liquid kinetic energy attenuation box 1 or the slag settling box 3. Of course, the grid plate can also be arranged at the joint surface between the slag liquid kinetic energy attenuation box and the sediment box under the condition of ensuring the sealing. In this embodiment, in order to optimize the diversion and screening effects, the grid plate 2 is preferably a steel grid plate, as shown in fig. 3, the steel grid plate is a specially-made large-particle slag screening device, which can attenuate the kinetic energy of the liquid flow of the slag slurry, make the liquid flow evenly distributed into the grids, force the liquid flow to move downwards, and filter the large rock mass, thereby ensuring the normal operation of the sediment conveying device 4.

The operation with low requirement on the returned drilling fluid can save a hydraulic cyclone sand removal device.
The operating principle of the hydrocyclone 9 is as follows: by adopting a centrifugal sedimentation separation mode, drilling slag liquid enters the cylindrical part from the liquid inlet pipe 10 to form a rotational flow, and is separated due to different densities or particle sizes under the action of inertial centrifugal force. The hydrocyclone 9 can separate and discharge fine sand in the drilling slag liquid, and can carry out classification, separation and concentration on a plurality of immiscible slurries, and the separated drilling slag liquid is led to the outlet of the slurry return tank 7 and flows back to the drilling along with the rest drilling slag liquid after deslagging.

And drilling slag in the drilling slag liquid is precipitated in the sediment tank, the drilling slag is discharged by the screw conveyor, and the drilling slag liquid separated by precipitation overflows from an overflow port at the upper part of the sediment tank and enters the slurry return tank.
