Slow-release water-soluble fertilizer anti-caking agent raw material screening device

Abstract

This utility model relates to the technical field of slow-release water-soluble fertilizer production equipment, specifically disclosing a slow-release water-soluble fertilizer anti-caking agent raw material screening device, including: a cabinet, which is a rectangular box for screening water-soluble fertilizer anti-caking agent raw materials. A screening box is installed at the upper end of the cabinet, and a centralized hopper is located at the top of the screening box. The centralized hopper is the main centralized device for feeding the slow-release water-soluble fertilizer anti-caking agent raw materials. This slow-release water-soluble fertilizer anti-caking agent raw material screening device forms a dynamically stable transmission through a sliding connection structure between the guide groove and the screening mesh belt, combined with the tension support of the drive roller and the auxiliary roller. The auxiliary spring plates at both ends of the auxiliary roller slide elastically along the slide rail on the side wall of the cabinet, which can automatically compensate for the tension changes of the screening mesh belt through the spring force, avoiding the slack of the mesh belt caused by vibration, so that the screening mesh belt always maintains a stable tension during high-frequency operation, ensuring that the screening accuracy is not affected by vibration, and reducing the equipment failure rate caused by the loosening of the mesh belt.
