AI Technical Summary
Technical Problem
Existing grinding equipment is prone to particle splashing and dust emission during use, posing a safety hazard.
Method used
The grinding device features a double-layer anti-splash design, including a high grinding chamber and a dust collection chamber. It is equipped with a filter plate and an air pump, and uses an electric push rod and guide rod to control the gap between the grinding seats. Through holes are set to guide dust, and sliding pins knock the filter screen to prevent clogging, forming a negative pressure dust collection chamber.
Benefits of technology
Significantly reduces particle splashing, prevents dust from escaping, ensures safety and grinding efficiency, and adapts to the needs of samples with different particle sizes.

Abstract
The utility model discloses a metallurgical test sample grinding device with a splash-proof structure, which comprises a base, a rack fixedly connected onto the base, a motor fixedly mounted on a top plate of the rack, a driving shaft connected to an output shaft of the motor, and a grinding seat connected to the driving shaft, and is characterized in that a dust collection bin with an open top is fixed on the base; a grinding bin matched with the grinding seat and used for grinding samples is fixed in the dust collecting bin, an upper port of the grinding bin is higher than an upper port of the grinding seat, and an upper port of the dust collecting bin is higher than an upper port of the grinding bin; a filter plate is fixed between the grinding bin and the dust collection bin, the space below the filter plate is a dust collection chamber, and one side of the dust collection chamber is connected with an air pump. The utility model aims to solve the problem that the existing grinding device with an open structure is very easy to generate particle splashing and dust dissipation in the use process.
