Inert gas protection airflow explosion explosion. The whole system has explosion-proof holes in different positions in the whole line, which minimizes the loss during the bursting and explosion caused by the internal pressure and concentration of the system. The motor and other devices used in the whole system are explosion-proof motors, and the sealing performance is better, which effectively reduces the accumulation of dust.The airflow pulverizer uses a high-speed airflow to drive the material, so that the material particles are hit by each other, and the shear has achieved ultrafine pulverization purposes, because its excellent pulverization effect is favored by powder producers from various industries.
Typical materials of airflow mills are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine, biochemical, etc., low temperature requirements: medicine, PVC. By change the ordinary air of the gas source to nitrogen, carbon dioxide gas, etc., the unit can be made into an inert gas protection device, which is suitable for the pulverization classification of materials such as flammable explosive, easy oxidation. Safety issues for the manufacture of ultrafine powder in the airflow mill include a respiratory dust and dust explosion. The dust particle diameter obtained by the gas flow pulverizer is basically 5 μm or less, while the dust of 5 μm or less to the human body is the most harmful. Therefore, the probability of using airflow crusher traces operators with dustpulmonary occupational disease will increase significantly. At the same time, the dust is largely scattered in the air to form a dust cloud, and dust explosions may occur. Since the dried dust particles in the airflow pulverizer have a suitable particle size and distribution state: generally less than 5 μm in the air, the dispersion stability in the air is good, and the explosion limit is very easy to achieve. The consequences of dust explosions are also extremely serious.
If there is sufficient fire air around these particles and there is a minimum ignition, dust explosion is prone to occur. Moreover, the impact wave produced by the local dust cloud explosion makes a large amount of deposition dust and mix with the air, and it is possible to form a secondary explosion. Since dust explosion has energy, severe damage, short break, shortness of breaking, which is easy to cause incomplete combustion, resulting in a large amount of carbon monoxide gas to make people poisoned. Therefore, the consequences of dust explosions are also extremely serious.
How many points do you need to pay attention to in daily maintenance?
1, during the production process, the bearing of the gas flow crusher must often be lowered, and when the temperature rise exceeds 50 ° C, it should be closed, and the reason is to rule out the fault.
2, when the airflow pulverizer is running, the transmission belt is easy to elongate, and should pay attention to adjust the right loose belt.Tightness to ensure the work life of the belt.
3, if the loss case should be checked frequently, replace the quality and production volume in time.
4, the blade, the lining should often check the wear situation. If the wear is worn, the productivity decreases, and the particle size is replaced after the particle size is replaced.
5, the host and the grading flow bearing are lipids, and the 2 special lipids are used 265-295.
6, the gas flow pulverizer bearing is 2000 hours, and the filling of the grease is 1/2 (episode) or 3/4 (lower test) of the space in the bearing cavity. Otherwise, it will cause too high of the bearing temperature.
7. The spiral feeder has changed the lipid period of 4,000 hours, and the calcium based grease is added.
In fact, each mechanical equipment has certain hazards when used, and the fluidized bed airflow pulverizer is the same, which requires us to master its use, standardize operation, scientific maintenance, can reduce the danger chance to lowest.
For AlPa powder, the craftsman is not just a concept, attitude and inheritance, and is a gene, one of the various links such as R & D, manufacturing, marketing, service and culture. The trampton who is lean for decades, such as the pursuit of vocational skills, more purely, relying on drilling and inheritance, explains the spiritual connotation of the craftsman, and creates one "alPa manufacturing".
