AI Technical Summary
Technical Problem
During drilling in a mine, water and slag inside the blowout preventer can flood into the gas storage tank, reducing the storage space. Existing technology makes it difficult to automate drainage control, which affects the effectiveness of the blowout preventer.
Method used
Design a negative pressure automatic drainage device that connects to a control component via a high-pressure pipe. By utilizing pressure changes to control a nylon piston and a solid rubber ball in a vibrating screen, the device automatically controls the opening and closing of the drainage pipe, ensuring no gas leakage.
Benefits of technology
It achieves automated drainage, responds promptly, prevents water and slag from entering, and improves the efficiency and safety of the blowout preventer.
