AI Technical Summary
The existing dust-free feeding stations are prone to affect the negative pressure structure and the conveying pipeline when feeding negative pressure due to the vibration screen structure being blocked by the material. The vibration screen structure is a single-layer structure, and it is difficult to separate the non-passing objects from the cylinder.
A dust-free feeding station is designed, and the air inlet and discharge port are set up to connect the air pressure on the upper and lower sides of the screen to reduce the impact of negative pressure on the vibration process. The cylinder is divided into three sections, so that the removable screen section with the screen can be detached, making it easy to remove the non-passing objects.
The risk of screen blockage is reduced through the air pressure communication, and the removable three-stage structure is used to facilitate the removal of non-pass objects, improving the reliability and operational convenience of the equipment.
