Description

Technical Field:

[0001] The present invention relates to the field of hopper mechanism design, and in particular to a hopper mechanism and a cuttings treatment system for a jack-up drilling platform. Background Art:

[0002] In some equipment systems, it is necessary to load and connect different other equipment through a hopper mechanism. For example, the cuttings treatment system of a jack-up drilling platform is divided into oil-based mud cuttings treatment and water-based mud cuttings treatment. Since oil-based mud pollutes the marine environment, the cuttings after being treated by the cuttings treatment system cannot be directly discharged into the sea. Instead, one or several screw conveyors are required to transport the cuttings to a cuttings collection tank on the main deck for centralized treatment. For the cuttings of water-based mud, they can be directly discharged into the sea through the cuttings. However, in order to ensure smooth discharge of the cuttings and convenient installation and operation of the discharge hose, we need to install a cuttings discharge hopper at the tail of the main deck.

[0003] Currently, most hoppers in the prior art adopt welding and fixed connection methods, which cannot meet the requirements of the sliding system in the X-Y degrees of freedom. Therefore, there is an urgent need for a hopper mechanism and a cuttings treatment system for a jack-up drilling platform, which helps to solve the technical problem in the prior art that there is no hopper structure corresponding to the requirements of different degrees of freedom sliding systems.
