Copper dedicated vibration fluidized bed dryer
Copper with a red shiny metal, have some harm to the environment, water, soil and atmospheric light pollution. Selection ZDG vibration fluidized bed dryer, the machine advanced design, simple operation, the choices are fully sealed structure, effectively prevent cross infection between the material and the air.
Copper Health hazards: Inhalation of large amounts of copper fumes may cause metal fume fever. Patients have chills, fever, accompanied by respiratory tract irritation. Long-term exposure to copper dust workers often contact dermatitis and nose, eye irritation, causing sore throat, cough, nasal congestion, rhinitis, or cause nasal septum perforation. Long-term inhalation can still cause lung fibrosis.
Copper: Formula Cu, the molecular weight of 63.55, with a red metallic luster, with a certain environmental hazards, water, soil and atmospheric light pollution. Its powder when the temperature, the fire will burn, dust irritant.
Refers to the size of the metal powder is less than 1mm metal particle group. It comprises a single metal powder, alloy powder and certain refractory metal compound powder having the properties, the main raw material powder metallurgy. Metal powder metallurgy products can be used as a raw material, it can also be applied directly.
ZDG series vibration fluidized bed dryer the material from the feed inlet into the machine, under the effect of the vibration motor excitation force or otherwise made available in the air distribution plate jump forward, and after the air was filtered, heated to a certain temperature, the air into the dryer under the wind chamber, the material in the hot air dual role of vibration force and through the air distribution plate are the wind, in suspension with the hot air contact, a fierce turbulence between material particles and the heat medium so that heat and mass transfer process can be strengthened, the dried product is discharged from the discharge port, evaporated water and exhaust gas recovered by the cyclone dust into the atmosphere. Bed body to the bed provides a stable with a certain pressure plenum. Adjusting fan, so that the upper portion of the box in the bed material to maintain slightly negative pressure, to maintain a good dry environment and prevent dust leakage.
1, the material is heated evenly and heat exchange is fully dry and high intensity, energy-efficient than conventional dryer about 30%. Vibration source is driven by vibration motor, smooth operation, easy maintenance, low noise and long life. Stable fluidization, no dead ends and broken phenomenon. Little damage to the surface of the material can be used for brittle dry material particles does not affect the effect of irregular work.
2, fully enclosed structure, effectively prevent cross-contamination between the air and the material, the working environment clean. Adjustable resistance, wide adaptation, material thickness and moved inside the machine speed and amplitude can be adjusted steplessly.
3, since the vibrations are applied, can reduce the minimum fluidizing gas velocity, which can significantly reduce the demand for air, thereby reducing the entrained dust layer, matching heat, fans, cyclones and other specifications can also be reduced accordingly, reducing equipment, energy-saving effect obvious. Can easily adjust the vibration to rely on parameters to change residence time in the dryer. Its plug flow operation reduces the particle size uniformity of the material and regulatory requirements, easy to obtain a homogeneous dry product
