AI Technical Summary
The existing equipment only performs one screening of the sand in the sand tank, which cannot achieve multi-stage screening. This results in a messy particle size distribution of the sand, making it impossible to effectively control the quality of the raw sand. Furthermore, impurities enter the sand tank, affecting the quality of the sand. In addition, repeated operations waste manpower, time, and energy, reducing production efficiency.
Design a sand jar with multi-stage screening function. Through internal multi-stage screens and a bidirectional motor-driven vibration mechanism, multi-stage screening of sand is achieved. Combined with springs and weights to generate centrifugal force, precise separation of particles of different sizes is achieved. The adjustable screen mesh and stable clamping structure facilitate the replacement and cleaning of the screening mechanism.
It achieves multi-stage precise separation of sand, improves the quality control of raw sand, avoids the entry of impurities, extends the service life of equipment, and improves production efficiency and the stability of the screening structure.
