This utility model relates to the field of waste zinc raw material pre-purification technology. Its key technical points are: it includes an installation frame; a second magnetic separation mechanism is movably connected to the front right side of the installation frame; a first magnetic separation mechanism is movably connected to the front middle of the installation frame; the first and second magnetic separation mechanisms have the same structure; a conveyor belt is installed inside the installation frame; support legs are fixedly connected to the four corners of the lower end of the installation frame; a control panel is fixedly connected to the front left side of the installation frame; a feeding device is fixedly connected to the front left side of the installation frame; and the control panel is located between the feeding device and the first magnetic separation mechanism. This multi-stage magnetic separation device, through its magnetic separation mechanism, can reduce manufacturing costs and decrease enterprise expenses.

[0003] However, there are problems with the existing technology: the magnetic material adsorbed on the surface of the adsorption cylinder is cleaned by the inclined scraper, and the magnetic material inside the scraper slides down and is discharged by utilizing the inclination of the scraper. However, there is friction between the magnetic material and the inner wall of the scraper. When the magnetic material cannot slide automatically, it will accumulate inside the scraper. When the scraper is full of magnetic material, it will overflow, causing the magnetic material to fall back to the top of the conveyor belt, which reduces the magnetic separation efficiency of waste zinc raw materials.
