Switchable rock debris distribution box

Abstract

The invention belongs to the technical field of marine module drill drilling, and discloses a switchable rock debris distribution box. The switchable rock debris distribution box includes a distribution box body with an upper opening, and the distribution box body is located below a rock debris discharging main pipe; a bottom plate of the distribution box body is formed by a horizontal plane and inclined faces, wherein the horizontal plane is located at the middle, and the inclined faces are located at the two sides, a sea discharging port and a collection port are formed in the inclined facesof the bottom plate of the distribution box body, and a liquid discharging port is formed in horizontal plate of the bottom plate of the distribution box body; a fixed baffle is arranged on the portion, at one side the sea discharging port, of the interior of the distribution box body and is used for leading rock debris into the sea discharging port; a rotary baffle is arranged at the portion, atone side the collection port, of the interior of the distribution box body and is used for switching and leading the rock debris into the collection port. According to the switchable rock debris distribution box, box interior switching is adopted to replace valve switching, therefore, the construction cost is reduced, the defects are overcome that because a valve is not closed tightly, the rock debris with oil is discharged into sea and then pollutes environment, and the switchable rock debris distribution box has the advantages of being simple in structure, various in function, good in economical efficiency and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of offshore module drilling rig drilling, and in particular relates to a cuttings discharge device. Background technique [0002] A large amount of cuttings will be produced during the drilling operation of the offshore module drilling rig. Since the discharge mainly depends on gravity, the cuttings are easy to form accumulation or blockage in the discharge pipeline. The pipeline for conveying the cuttings needs to be set with a large slope. Flush and unclog. [0003] Based on environmental protection requirements, two processes are usually set up for cuttings discharge, sea discharge and recycling. The cuttings discharge of offshore module drilling rigs is basically composed of 14”pipes, tee fittings, valves and other components to complete the purpose of cuttings discharge. Two processes need to be set up. The valve controls the switching of the two processes. Due to the large size and weight of the two v...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the technical problem that cuttings of marine module drilling rigs are easy to form accumulation or blockage in the discharge pipeline, and provide a switchable cuttings diversion box, which uses the internal switching of the box instead of the switching of the valve to reduce the construction cost and avoid It eliminates defects such as oily cuttings being discharged into the sea to pollute the environment due to lax valve closure. It has the characteristics of simple structure, rich functions, good economy and strong practicability.
