Material for box production:

Overview of machine structure: This product adopts two side air ducts for air outlet and a middle air duct for air return circulation. It uses a PTFE conveyor belt, which is relatively flat. The feeding end is 200mm, and the drying section is heated by an electric heating tube with a total length of 3000mm (the drying section is divided into two groups: 1500+1500mm, which can work independently with temperature control). The discharge end is 800mm. The electric heating tube is installed in the air duct at the top of the oven, and the circulating motor is installed at the top of the oven to extend the service life of the motor. The inlet and outlet are equipped with adjustable insulation boards that can be freely adjusted up and down, and insulation boards are installed on the inside for double-layer insulation. *Stainless steel protective wire mesh is installed on the top of the heating box to prevent the product from being rolled into the wind turbine

Outer wall material of the box: A3 carbon steel cold rolled plate, sheet metal, bent welding, rivet splicing.

Box air plate material: SUS304 mirror stainless steel plate sheet metal bending machine punching.

Box frame material: A3 carbon steel cold rolled plate, sheet metal bending and weldingmake.

Box tripod material: made of national standard square tube

Insulation layer thickness material: filled with 100K grade high-density aluminum silicate fiber (insulation layer thickness of 100mm).

Outer box coating material: After rust proof phosphating treatment, the surface is sprayed with plastic, and the color is blue and white

Transmission power system:

Transmission power: 1 gear speed regulating motor is used, with a speed range of 1m-10m/min.

Conveyor drum: adopts self correcting drum, which can be adjusted left and right for correction.

Variable frequency drive: using a variable frequency speed controller

Conveyor belt: Made of PTFE conveyor belt, relatively flat and easy to clean.

Intake and exhaust:

Air intake: 3 holes with a diameter of 60mm. Located next to the circulating motor, it serves as a compensating air intake for cold air.

Exhaust: 2 adjustable butterfly valve exhaust ports to eliminate baking exhaust gas

Circulating system:

Blowing method: high-pressure circulating air

Motor device: 3 180W long axis motors installed on the top of the box

Heating system:

Heating element:Infrared heating uses 24 1KW infrared lamps. The electric heating tube adopts a covered stainless steel heater for dust-free U-shaped stainless steel tubular electric heating generator, with a capacity of 1KW per piece and a total of 24 pieces. The total power of the heating element is 24KW, divided into 2 sets of heating switches, and the continuous service life can reach more than 40000 hours

Heating time:The heating rate is required to be above 2 ℃/minute and cannot exceed 10 ℃/minute. Raise the temperature from room temperature to 60 ℃ for no more than 10 minutes, and from room temperature to 200 ℃ for no more than 30 minutes.

Electrical configuration:

Temperature controller: LED/intelligent/digital display/temperature controller, temperature control accuracy ± 1 ℃, with P.I.D adjustment, automatic constant temperature.

Divided into 2 groups for heating control, 2 temperature control instruments independently control the temperature inside a section of the box. Assembled in one control box, located at the discharge outlet

Sound and light alarm device: APT/AD16 type sound and light alarm device, set time end alarm prompt.

Control circuit voltage: 220V/50Hz

Temperature measuring device: 2 stainless steel armored PT100 resistance temperature sensing devices+2 K-degree thermocouples, with a temperature measurement accuracy of ± 1 ℃.

Protection system: leakage protection, circuit breaker protection, motor overload protection, grounding protection, over temperature protection.

Circuit breaker activation: Circuit breakers with leakage protection are activated to effectively protect all electrical components.

Main control output: using SSR solid-state relay output, precise temperature control

Electrical components: use branded electrical products
