en.Weodoany.com Report on Mar 27th, Zijin Mining Group has newly obtained a utility model patent grant, titled "An Automatic Cleaning Vibration Screening Device for Lead-Zinc Ore". The patent application number is CN202520437476.5, and the grant date is March 27, 2026.
Patent Abstract: This utility model discloses an automatic cleaning vibration screening device for lead-zinc ore, comprising a vibration screen frame. Multiple screen meshes are fixedly installed inside the vibration screen frame. High-pressure cleaning pipelines are movably arranged inside the vibration screen frame, located below the multiple screen meshes. An angle adjustment mechanism connected to the high-pressure cleaning pipelines is provided on one side of the vibration screen frame. A water storage tank is located on one side of the vibration screen frame, and a water pump is fixedly installed on the top surface of the water storage tank. The electric push rod drives the U-shaped adjustment bracket to move up and down. Since the rack installed on one side of the U-shaped adjustment bracket meshes with the semicircular gear, it causes multiple sets of high-pressure cleaning pipelines to rotate, allowing them to clean the screen meshes over a large area at a certain angle. This effectively prevents screen mesh clogging and improves cleaning efficiency. This utility model, through the coordinated operation of multiple sets of high-pressure cleaning pipelines, the water pump, and the angle adjustment mechanism, can achieve large-area cleaning of multiple screen meshes inside the vibration screen frame, thereby improving work efficiency.
