Copper dedicated vibration fluidized bed dryer
Detailed description
Copper dedicated vibration fluidized bed dryer
project description:
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.
Item Description:
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.
principle:
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.
Features:
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
