AI Technical Summary
Technical Problem
Coal spiral samplers are prone to blockage during the sampling process due to large pieces of coal or clumps, which can affect the normal progress of the sampling process.
Method used
Large pieces of coal are pre-filtered using an anti-clogging filter screen, and large pieces of coal are crushed using an anti-clogging component. The smooth sampling process is ensured through a synergistic design of screw conveyor and inner wall cleaning.
Benefits of technology
It effectively prevents coal from clogging the sampling tube, ensuring the continuity and stability of the sampling process and improving sampling efficiency and accuracy.
