AI Technical Summary

Technical Problem

Existing liquid conveying devices have problems with inclined feeding, especially the feeding obstruction caused by the height difference between the online measuring device and the measuring supply tank.

Method used

A liquid conveying device was designed, including a feeding trough, a buffer tank, first and second air lifting devices, a measuring supply tank, and an online measuring device. By setting a height difference and a return pipeline, the first end of the online measuring device is ensured to be lower than the lowest point of the measuring supply tank, and the conveying is carried out in a sealed shielded container. The liquid is conveyed using a non-mechanical air lifting device.

Benefits of technology

It improves the difficulty of inclined feeding in the liquid conveying device, enhances the accuracy of online measurement and the stability of the system, ensures radiation safety performance, and reduces equipment length and cost.
