Solid-liquid mixtures such as drill cuttings, mud and the like from a drilling machine enter the vibrating screen 1 through the overhead manifold for treatment, when the solid-liquid mixtures leave the vibrating screen 1, the solid-liquid mixtures automatically flow into the drill cuttings solid-liquid separation chute 2, when the materials pass through the first screen 203, the first solid-liquid separation is carried out to generate a primary solid phase (the drill cuttings, namely rock debris generated in the drilling process) and a primary liquid phase (mainly mud), the primary solid phase automatically slides into the secondary solid phase collection hopper 301 on the drill cuttings collection and conveying skid-mounted unit 3 through the primary solid phase chute 201, the primary liquid phase enters the primary liquid phase collection cavity 202 through the first screen 203 for temporary storage and automatically flows or is pumped into the secondary liquid phase collection cavity 302 on the drill cuttings collection and conveying skid-mounted unit 3 through a pipeline, and the drill cuttings solid-liquid separation chute 2 mainly plays a role in coarse separation of the solid-liquid mixtures discharged from the bottom, although the primary liquid phase generated by the separation also contains a great deal of rock debris, and the primary solid phase is also attached with a great deal of liquid phase substances such as slurry, compared with the prior art that the primary solid phase is not pretreated and directly enters a rear drill chip non-landing system, the arrangement of the drill chip solid-liquid separation chute 2 can reduce the workload of the subsequent further solid-liquid separation process, and is beneficial to improving the final solid-liquid separation effect and the final harmless treatment effect of the drill chips.

The drill cutting collecting and conveying skid-mounted unit 3 has the main function of intensively collecting the primary solid phase and the primary liquid phase generated by the drill cutting solid-liquid separation chute 2 in the previous step, and then intensively conveying the collected primary solid phase and the collected primary liquid phase into the drill cutting treating skid-mounted unit 4 for more refined solid-liquid separation treatment. Compared with the prior art only having the function of collecting and transferring slurry, the skid-mounted unit 3 for collecting and conveying drill cuttings has the main advantages that the second screen 304 can be used for carrying out solid-liquid separation (secondary solid-liquid separation) on a primary solid phase entering the secondary solid phase collecting hopper 301 again, the workload of a rear further solid-liquid separation process can be further reduced although the primary solid phase is roughly separated, and the final solid-liquid separation effect and the final harmless treatment effect of the drill cuttings are promoted.

And this system has set up drill chip and has mixed and mix sled dress unit 5, this innocent treatment effect that just can promote the thermal desorption system 8 of detritus in with among the gas cleaning system 9 greatly reduces the risk of secondary treatment detritus and flue gas, has practiced thrift the treatment cost.
