The explosion-proof centrifuge is a new type of centrifuge. Recently, 7 explosion-proof centrifuges ordered by Zhejiang have been shipped out of the warehouse and sent to customers. Explosion-proof means that electrical equipment working in an explosive atmosphere has sparks in itself. When it does not cause environmental explosion, the solid-liquid specific gravity difference is utilized, and the centrifugal force field is used to expand it several thousand times. The solid phase is settled under the action of centrifugal force, thereby realizing solid-liquid separation and discharging the body separately under the action of a special mechanism. The entire feed and separation process is continuous, closed, and automated.
Because the centrifuge adopts a closed nitrogen filling system device (closed refers to toxic and harmful, non-leakage of flammable and explosive materials), it can effectively discharge the air inside the machine to prevent the material from being flammable and explosive, and has nitrogen protection throughout the separation process. , greatly improving the separation of materials and workplace safety.
The explosion-proof centrifuge is mainly used for volatile solid materials, dustproof purification, flammable and explosive places for solid-liquid flameproof separation, and is suitable for petroleum, chemical and other industries.
Whether the centrifuge needs to be sealed and explosion-proof depends on the environment and conditions used.
In recent years, users have had explosion-proof requirements for centrifuges. These media have organic solvents such as methanol, ethanol, toluene, etc. The safety of the centrifuge during operation has become the primary requirement for selection.
There are several elements that cause combustion and explosion;
1: Temperature, fire source, oxygen. Temperature: For a specific medium, whether it is liquid phase or gas phase, the operating temperature when entering the centrifuge should be considered when designing the process, and should not be higher than the ignition point.
2: Fire source, when designing the centrifuge, there should be enough safety space for the moving parts to eliminate possible mechanical friction and impact. The machine must have measures to eliminate static electricity. For brake devices, the form of dynamic braking is generally used (non-contact braking, the disadvantage is that the braking time is longer than the contact type, especially when the inertia is large at full load) Do not use mechanical friction brakes. For the drive belt, an antistatic belt is used to eliminate or reduce the possibility of static electricity generation.
3: Oxygen, when it comes to explosion-proof occasions, we first thought of using nitrogen protection, that is, filling the inside of the centrifuge with nitrogen to keep the oxygen concentration within the safe range, but if it is simply to set a nitrogen inlet pipe on the casing A nitrogen outlet pipe, the centrifuge is filled with nitrogen gas during operation, and there is no quantitative control as to the nitrogen concentration, so the reliability of nitrogen protection is very low.
The company designed a nitrogen protection device for high explosion-proof occasions and got a good application. (The specific control technology can communicate with our technicians, our company is willing to help you.) For the use of explosion-proof requirements, the appropriate configuration should be proposed according to the actual process and environment. When ordering, more precise manufacturing requirements should be imposed on the configuration of the centrifuge.
Shanghai Lu Xiangyi is a Chinese centrifuge company that has obtained FDA certification. It has been in development for more than 40 years. The headquarters is located in Zhoupu Industrial Park, Pudong New Area, Shanghai. It covers an area of 7,000 square meters and has a standard factory building of 9,000 square meters. At present, we have established technical cooperation with centrifuges for the supply and stability of centrifuge products with many well-known universities, hospitals, petrochemicals, pharmaceutical companies, food companies, high-tech enterprises and scientific research units. We are willing to establish a broader technical cooperation relationship with domestic and foreign enterprises to achieve a better future together.
