Description

Technical Field

[0001] This utility model relates to the field of tungsten powder processing, specifically a safety device for feeding tungsten powder. Background Technology

[0002] Tungsten powder feeders are devices used for the automatic intermittent or continuous metering of powdered and granular materials such as tungsten powder. Tungsten powder is the main raw material for processing powder metallurgy products and tungsten alloys. Tungsten powder can be made into processed materials such as wires, rods, tubes, and plates, as well as products of certain shapes. When mixed with other metal powders, tungsten powder can be made into various tungsten alloys, such as tungsten-molybdenum alloys, tungsten-rhenium alloys, tungsten-copper alloys, and high-density tungsten. Another important application of tungsten powder is to make tungsten carbide powder, which is then used to prepare cemented carbide tools such as lathe tools, milling cutters, drill bits, and molds.

[0003] Existing technologies still have certain drawbacks in the process of feeding tungsten powder. When traditional tungsten powder feeding equipment is used, some powder will fly into the air and be easily inhaled by the feeding personnel, which can cause harm to the human respiratory tract or lungs and pose certain safety hazards. It cannot guarantee the personal safety of the feeding personnel. Utility Model Content
