AI Technical Summary

Technical Problem

The long nozzle mounting bracket of existing quartz sand color sorters increases airflow resistance, reduces the response speed of the spray valve, and is prone to nozzle plate position displacement due to vibration and temperature difference, requiring frequent correction, which affects color sorting accuracy and increases production costs.

Method used

The system adopts a grouped short nozzle mounting bracket structure, with nozzle mounting plates, nozzle support brackets, and V-shaped nozzle plates evenly arranged. The nozzle plate distance can be adjusted by debugging and calibrating the waist holes to enhance rigidity, reduce air pipe length, reduce airflow resistance, and improve the response speed and positional stability of the spray valve.

Benefits of technology

It improves color sorting accuracy, reduces the carry-out ratio, reduces waste of high-quality raw materials, lowers production costs, and ensures the positional stability of the nozzle plate and the color sorting effect.
