Description

Technical Field

[0001] The utility model relates to a dust recovery device for tungsten powder or tungsten carbide powder, in particular to a dust recovery device for tungsten powder or tungsten carbide powder with a flushing mechanism. Background Art

[0002] Tungsten carbide powder is the primary raw material for producing cemented carbide. It is a black hexagonal crystal with a metallic luster and a hardness similar to that of diamond. It is a good conductor of electricity and heat. It has a melting point of 2870°C, a boiling point of 6000°C, and a relative density of 15.63 (18°C). Tungsten carbide is insoluble in water, hydrochloric acid, and sulfuric acid, but is readily soluble in a mixture of nitric acid and hydrofluoric acid. Pure tungsten carbide is brittle, but its brittleness can be reduced by adding small amounts of metals such as titanium and cobalt. Tungsten carbide used as steel cutting tools is often added with titanium carbide, tantalum carbide, or a mixture thereof to improve its explosion resistance. Tungsten carbide is chemically stable.

[0003] After long-term use, a thick layer of dust will form on the inner wall of the existing dust collection duct. The inner wall of the dust collection duct is difficult to clean. The accumulated dust will reduce the ventilation efficiency of the duct and increase the weight of the duct. Therefore, when the inner wall of the dust collection duct needs to be cleaned, the duct needs to be disassembled and cleaned. The dust on the inner wall of the duct is subjected to severe vibration and will fall off and diffuse in the air, affecting the health of workers, causing waste of resources and polluting the environmental sanitation of the production workshop.
