[0002] Explosion-proof centrifuge is a new type of horizontal screw centrifuge, which is mainly used for solid-liquid explosion-proof separation of volatile materials, dust purification, and flammable and explosive places. It is widely used in petroleum, chemical, pharmaceutical, food and other industries. If you want to use explosion-proof centrifuge safely and reliably, you must have a safe, reliable and explosion-proof control box.

[0003] Centrifuges often use digital tubes, LED screens, LCD screens and other devices as human-computer interaction systems. These devices are directly installed in the centrifuge structure. Their LED screens or LCD screens do not have explosion-proof capabilities. Generally, a protective cover is added to the control box to protect the LED screen or LCD screen. The protective cover used in the control box on the market currently has a relatively single function and its protective effect is not ideal. When impacted, the protective cover is easily deformed and may squeeze the internal display or LCD screen, causing damage to the display device. Utility Model Content
