Straight drum dryer

A straight drum dryer is a common drying equipment, and the following is a detailed introduction about it:

Structural composition:

Drying box component: It is the outer shell part of the straight drum dryer, providing a relatively enclosed space for the entire drying process to ensure the circulation of hot air inside and avoid heat loss. Its material usually has good insulation performance and a certain strength, which can withstand temperature changes and mechanical stress during equipment operation.

Conveyor device: Multiple conveyor devices are suspended in a staggered manner inside the drying box component. The conveying device is used to transport the straight cylinder to be dried along the preset conveying direction, mainly composed of a conveying wheel, a conveyor belt, and a conveying shaft. The conveyor wheel is located at both ends of the conveyor belt, playing a role in supporting and driving the operation of the conveyor belt. The conveyor shaft runs through the conveyor wheel and is connected to the drying box component, transmitting power to the conveyor wheel to ensure the continuous and stable operation of the conveyor belt.

Guide plate: One end of the guide plate is inclined towards the conveyor device, and its function is to adjust the movement trajectory of the straight cylinder during the process of being transported from one conveyor device to another, ensuring that the straight cylinder can smoothly transfer between conveyors and avoiding situations such as jamming or falling.

Drive device: provides power for the conveyor belt to operate, and is usually composed of components such as motors, reducers, couplings, etc. The motor provides the original power, and the reducer reduces the high speed of the motor to a speed suitable for the transmission device. The coupling is used to connect the motor and reducer with the transmission shaft, ensuring smooth power transmission.

Heat source device: provides heat for the drying process, common heat sources include gas, fuel, electric heating, etc. The heat source device needs to be able to generate sufficient heat and effectively transfer it to the drying box components to ensure that the straight drum can be fully dried.

Ventilation system: including air inlet and outlet, used to ensure air circulation inside the drying box components. The air inlet introduces fresh air into the drying box component, mixes it with the heat generated by the heat source device to form hot air, and dries the straight cylinder; The air outlet discharges moist and hot air containing moisture outside the drying box components, keeping the air inside the drying box components dry.

Working principle: The straight drum to be dried enters the straight drum dryer from the feeding port and falls onto the conveyor. The conveying device, driven by the driving device, transports the straight cylinder in the predetermined direction and speed. During the conveying process, the straight cylinder will pass through multiple conveying devices arranged in a staggered manner, extending its residence time in the drying box components. At the same time, the hot air generated by the heat source device enters the drying box components through the ventilation system and comes into full contact with the straight cylinder, gradually evaporating the moisture in the straight cylinder. The moist and hot air containing moisture is discharged from the air outlet, processed and discharged to the outside, while the dried straight cylinder is sent out from the discharge outlet to complete the entire drying process.

Application areas:

Fireworks industry: used for drying straight fireworks tubes. During the production process of fireworks, the tubes need to be dried to remove moisture and ensure the quality and safety of the fireworks. The straight tube dryer can provide a stable drying environment, ensure the drying effect of the straight tube, and thus improve the production quality of fireworks.

Chemical industry: can be used for drying chemical raw materials in straight tubes, such as some plastic straight tubes, rubber straight tubes, etc. In the chemical production process, these straight tubes need to be dried to remove moisture and other volatile substances from the raw materials, improving the purity and quality of the products.

Food industry: suitable for drying food packaging straight tubes, such as straight tube packaging for canned food. In the production process of food packaging, straight tubes need to be dried and disinfected to ensure the hygiene and safety of food. A straight drum dryer can sterilize and disinfect the straight drum while drying, improving the quality of food packaging.

advantage:

High drying efficiency: The design of multiple conveying devices allows the straight drum to fully stay inside the drying box components and make full contact with hot air, improving the drying efficiency.

Smooth material conveying: By setting the guide plate, the movement trajectory of the straight cylinder between the conveying devices can be effectively adjusted to ensure smooth material conveying and reduce the wear and damage of the straight cylinder.

Simple structure: Compared to some complex drying equipment, the straight drum dryer has a relatively simple structure and is easy to operate and maintain.

Strong applicability: The speed of the conveying device and the temperature of the heat source can be adjusted according to different materials and drying requirements, making it suitable for drying various straight tube materials.
