Description

Technical Field

[0001] This utility model belongs to the field of powder purification technology, specifically relating to a portable universal gas source cabinet assembly. Background Technology

[0002] High-purity graphite is a material with a variety of excellent properties. Due to its outstanding electrical conductivity, heat resistance, corrosion resistance, and stable chemical properties, it is widely used in electronics, power, chemical, metallurgy, machinery, and aerospace industries. As a raw material for graphite parts processing, the purity of high-purity graphite powder directly determines the physicochemical properties of the resulting graphite parts. However, because high-purity graphite powder is expensive, its production is generally achieved by purifying ordinary graphite powder. In the purification process, process gases are introduced into the purification equipment to further purify the graphite powder. The flow rate and velocity of the process gas directly determine the purity of the purified graphite powder; therefore, controlling the flow rate and velocity of the process gas is crucial during the purification process. The designed process flow differs when purifying different types of graphite powder, and each different process requires a different gas source cabinet to control the process gas. Redesigning the gas source cabinet every time not only reduces production efficiency but also increases costs. Therefore, a simple and efficient universal gas source cabinet assembly is not only an important prerequisite for graphite powder purification, but also an important guarantee for the large-scale mass production of high-purity graphite.
