Description

Technical Field

[0001] This utility model relates to the technical field of graphite centrifuge equipment, specifically a sealed explosion-proof graphite centrifuge equipment. Background Technology

[0002] Graphite, as an important industrial raw material, plays a crucial role in many production fields. The manufacturing industry has extremely stringent quality requirements for graphite, demanding not only a carbon content of over 99.9%, but also limiting the content of trace elements. Typical natural graphite has a maximum carbon content of 96%, which is insufficient to meet the demand for high-purity graphite; therefore, purification of natural graphite is necessary.

[0003] In graphite purification processes, chemical purification is the primary method. This method removes impurities from natural graphite by adding chemical reagents. After graphite treatment, it's crucial to separate the graphite from the slurry mixture. Incomplete separation of chemical reagents can lead to residues becoming new impurities, thus affecting the purity of the graphite powder. Vertical centrifuges are commonly used for separating graphite from the slurry mixture. It's essential to prevent the volatilization and leakage of chemical reagents outside the centrifuge and to prevent air from entering the centrifuge to avoid dangerous accidents such as explosions.

[0004] However, the internal condition of a centrifuge is not observable in a closed environment, making it difficult to determine the thickness of the separated graphite powder accumulation on the centrifuge's inner wall. If the centrifuge is opened too early, the graphite powder accumulation will be too small, and frequent switching on and off will reduce production efficiency; if the centrifuge is opened too late, the graphite powder accumulation will be too large, occupying a lot of space and affecting heat dissipation, and may also generate static electricity due to friction, creating a safety hazard.

[0005] Therefore, this utility model proposes a sealed explosion-proof graphite centrifuge to solve the above-mentioned problems. Utility Model Content

The drive motor 27 drives the conical dispersion disc 25 to rotate, and the rotating distribution arm 26 sprays the graphite evenly into the shaking bag 5. Then, the drive device 32 is activated. The high-speed rotating shaking bag 5 uses centrifugal force to make the liquid permeate through the filter holes of the shaking bag 5 and be discharged through the guide pipe 8 at the bottom of the sealed tank 1. During the discharge, the convex trapezoidal design of the tank body accelerates the liquid flow.
