Embodiment Construction

[0021] Such as figure 1 —— Figure 4 As shown, the present invention includes: a stirrer 5 installed at the bottom of the mixing tank 4 for mixing and stirring the antifreeze particles and water. A feeding tank 1 is installed on one side of the mixing tank 4, and the bottom of the feeding tank 1 is respectively connected to one end of two feeding pipeline pumps 2 through a pipeline, and the other end of the pipeline pump 2 is connected to a feeding pipeline, and the feeding pipeline is installed In the inlet of the mixing tank 4, the added raw materials are pumped into the mixing tank through the feeding pipeline pump 2. Two return pipes 10 are installed in the middle of the mixing tank 4, and the other end of the return pipe 10 is installed on the top of the feeding tank 1. A control valve is installed on the return pipe 10, and the liquid in the mixing tank 4 is returned by opening the control valve. In the upper feed tank 1, it is fully dissolved. Then, the mixed solutio...

Abstract

A ballast liquid preparation and delivery pry block is provided with a stirrer, wherein the stirrer is mounted at the bottom of a mixing tank; a feeding tank is mounted on one side of the mixing tank; the bottom of the feeding tank is connected with one end of each feeding inline pump through a pipeline; the other end of each inline pump is connected with a feeding pipeline; the feeding pipeline is mounted at the inlet of the mixing tank; a return pipeline is mounted on the mixing tank; the other end of the return pipeline is mounted on the feeding tank; a control valve is mounted on the return pipeline; one side of the mixing tank is connected with a plurality of export centrifugal pumps through a pipeline; and the other end of each export centrifugal pump is connected with an export pipe. The adoption of the pry block realizes automatic water feeding, feeding and liquid mixing, finishes the ballast liquid preparation and delivery functions, saves man power, shortens working period, reduces construction cost, and greatly improves the work efficiency.

Description

technical field [0001] The invention relates to a skid, in particular to a ballast liquid preparation and delivery skid capable of automatically adding water, feeding materials, mixing liquids, and completing the functions of ballast liquid preparation and delivery. It belongs to the field of offshore oil engineering. Background technique [0002] Offshore oilfield floating production and storage system (FPSO) is a large-scale production and storage ship mainly used for storage, production, processing and export of crude oil and natural gas, and provides water, electricity and life support for oil fields. It is the core facility for offshore oil and gas production. [0003] The mooring system is mainly composed of a single point mooring head, YOKE and mooring legs. The mooring legs and YOKE are used as a bufferable connection device to connect the offshore oilfield floating production storage system (FPSO) Long-term mooring on a single point enables the offshore oilfield f...
