AI Technical Summary

Technical Problem

When existing gasoline storage tanks are drained, sludge easily clogs the drain holes, making the operation cumbersome and difficult to clean.

Method used

An automatic drainage device for gasoline storage tanks was designed, comprising a temporary storage tank, a separating valve, a filter pipe, a filter cylinder, and a cleaning plate. The separating valve cuts off the connection between the temporary storage tank and the gasoline tank, enabling online cleaning and preventing the direct discharge of sludge. The filter cylinder and cleaning plate are used to filter and clean the sludge.

Benefits of technology

This allows for maintenance and cleaning without emptying the gasoline tank, preventing sludge from clogging the drain hole, simplifying the operation process, and ensuring drainage efficiency and sealing.
