AI Technical Summary
In the existing technology, during the construction process, the replacement of the filter paper tape in the existing beta-ray dust monitoring instrument requires climbing to a height, which makes the replacement inconvenient.
The design includes a monitoring box, support shaft, drive shaft, drive motor, partition, and hopper box. The design of the hopper box simplifies the filter paper belt replacement process, making it more convenient during the preparation and installation stages.
It reduces the time spent working at heights, simplifies the installation process of filter paper belts, and improves replacement efficiency.
