Description

Technical Field

[0001] This utility model relates to the field of screening technology for strong magnetic raw materials, and in particular to a high-efficiency screening device for strong magnetic raw materials. Background Technology

[0002] Screening of strong magnetic raw materials is a crucial process step. The main purpose of screening is to separate the raw materials according to particle size to meet the needs of subsequent processing or production. Screening removes large particles of impurities, improving the purity and uniformity of the raw materials. Given the characteristics of strong magnetic raw materials, suitable screening equipment must be selected. Common screening equipment includes vibrating screens and ultrasonic vibrating screens. These devices offer advantages such as high screening efficiency, high precision, and large processing capacity, meeting the requirements for screening strong magnetic raw materials.

[0003] In existing technologies, screening of strong magnetic raw materials requires the use of a strong magnetic raw material screening device. However, when recycling NdFeB waste, existing strong magnetic raw material screening devices can accelerate filter screen wear if the raw material contains insufficiently crushed sintered blocks. Stainless steel mesh is prone to pitting corrosion in a chloride ion environment. Magnetic material dust adheres and forms a galvanic cell effect, accelerating corrosion. At the same time, strong magnetic particles form "magnetic chains" on the filter screen surface, blocking the mesh holes, which are difficult to remove even with backflushing or vibration.

When the filter screen 4 needs to be replaced, the operator can use the handle 14 to pull the locking rod 13 to disengage it from the slot 17 inside the fixing post 5, and then rotate the handle 11 to use the anti-slip groove. The filter screen 4 can be easily disassembled or installed.

The transmission rod 23 is then movably connected to the bottom right side of the filter frame 3 through the second rotating shaft. When the drive motor 18 works, the power is transmitted to the second transmission wheel 21 through the transmission wheel and the transmission belt 20, thereby driving the transmission shaft seat 22 and the transmission rod 23, causing the filter frame 3 to reciprocate.
