1.Overview of the Process Scheme

The working process of the whole set of equipment: raw materials

— belt conveyor — crusher — belt conveyor — screw conveyor —

horizontal decoating carbonization decoating machine — discharger

— finished products; the whole set of equipment is equipped with 1

cyclone dust collector, a set of Venturi dust collector, and a flue gas

condenser. The following briefly describes the whole process from

feeding to discharging: In this set of processes, first, the aluminum

cans are conveyed to the crusher by the belt conveyor. After being

crushed by the crusher, the aluminum cans are sent to the carbonization

decoating machine by the screw conveyor for carbonization and paint

removal. The combustible gas emitted during the carbonization process

is led outside the carbonization decoating machine and ignited to

provide continuous heat for the carbonization pyrolysis. At this point,

the aluminum cans after carbonization and paint removal are turned

into aluminum sheets.

Overview of Carbonization: The main body of the carbonization

decoating machine consists of two nested inner and outer cylinders.

During operation, the materials enter the inner cylinder for carbonization

treatment. Since the heat source is located in the high-temperature area

in the middle of the outer cylinder and directly heats the inner cylinder

made of 304S material, the temperature of the cylinder will reach about

700 degrees Celsius. After preheating, the materials slowly pass through

the high-temperature area and undergo pyrolysis and carbonization reactions.

The carbonization decoating machine is equipped with a variable frequency

speed-regulating motor, which can adjust the rotation speed of the cylinder

at any time to control the carbonization temperature and time of the materials.

In this process, our goal is to make the materials undergo a high-temperature

carbonization reaction, and we cannot allow excessive oxygen to participate

in the reaction. Therefore, sealing is particularly important. For this machine,

we adopt a sealing type of labyrinth plus high-temperature resistant ceramic

fiber packing, which can better adapt to the axial displacement of the cylinder

and the circumferential ovality, so that the ceramic fiber packing can always

be in contact with the cylinder, thus achieving a good sealing effect. This

sealing is mainly located at the contact part between the feeding bin and the

inner cylinder, and the contact part between the discharging bin and the outer

and inner cylinders. The feeding screw conveys the materials to the inner

cylinder of the main machine. Since a large amount of water vapor will be

generated when the materials are carbonized in the inner cylinder, this water

vapor needs to be discharged in a timely manner. Therefore, an exhaust gas

pipeline needs to be set at the top of the feeding bin, and the exhaust gas is

pumped to the dust removal equipment by the induced draft fan for dust

collection treatment. The high-temperature exhaust gas in the heating furnace

of the equipment is collected and cooled by the primary dust removal equipment

(cyclone dust collector) and then enters the secondary dust removal equipment

(selected components) for further dust collection treatment before being

discharged into the air. Finally, the finished products are conveyed by the screw

conveyor at the lower part of the discharging bin to the next cooling process for

cooling treatment. After the cooling treatment, they are then packaged and formed.

The materials processed by the carbonization decoating machine have a

temperature of about 300 degrees Celsius. During the entire cooling process

when they enter the cooler, a sealing structure similar to that of the integrated

machine is required to isolate the air to prevent spontaneous combustion.

"Material sealing" is adopted at the discharging screw to prevent air from

flowing back. As for the negative pressure problem after the cooler cools

down, in this set of processes, it is considered to connect the sealing end

head of the cooler to the inner cylinder of the integrated machine for

compensation. After the problems of the cooler's sealing and pressure

compensation are solved, the cooling water continuously circulates and

cools down under the action of the water pump, gradually cooling the

finished products to about 30 degrees Celsius, and then they are pulled

out by the screw conveyor for standby. This equipment makes full use of

the pyrolysis of biomass and the waste heat of flue gas to dry the materials;

by optimizing and centrally designing multiple channels such as the tail gas

collection channel of the hot blast stove, the heat energy collection channel

of carbonization pyrolysis, and the flue gas collection channel, the heat

energy utilization is improved, thus achieving environmental protection and

energy conservation.

2. Application of the Decoating Furnace

In the recycling industry, Aluminum Cans Paint Remover is primarily

used to strip off the paint and coatings from aluminum cans. This is

a crucial step as it enables the separation of the pure aluminum

material, facilitating more efficient recycling. By removing the paint,

the aluminum cans can be melted down and reused with higher purity,

reducing the energy consumption and costs associated with the

recycling process.

Aluminum Cans Paint Remover plays a vital role in enhancing the quality

of recycled aluminum. It ensures that the aluminum obtained from

recycled cans is free from paint contaminants, which is essential for

producing high-quality aluminum products such as new cans, aluminum

sheets, and other aluminum-based materials.

For those engaged in the refurbishment of aluminum cans, Aluminum

Cans Paint Remover is an indispensable tool. It allows for the easy

removal of old and worn-out paint, preparing the surface of the cans

for repainting or other decorative treatments. This enables the

transformation of used cans into new-looking items, which can be used

for various creative purposes or even resold in the market.

In the refurbishment of aluminum cans for artistic or DIY projects, the paint

remover helps to create a clean and smooth surface. This allows artists

and DIY enthusiasts to apply new colors, patterns, or textures more

effectively, bringing out their creativity and adding value to the recycled cans.
