Product description



1. Composition and description:

The tunnel furnace is mainly composed of: conveying system, hot air drying system, automatic heating temperature control system, circulating air system, electrical control system; cooling and cooling system, etc.

The tunnel furnace adopts the relay automatic control form, except for manual loading and unloading of the workpiece, all other technological processes are automatically completed by it. Manually only need to place the workpiece to be dried in the leveling zone of the conveyor belt, and the conveyor system will automatically send the parts to each process section in sequence. After the workpiece is dried and cooled, it reaches the unloading station, and the drying process is completed. .

2. Conveying system
The tunnel furnace conveying system consists of a transmission, a conveyor belt, a main drive shaft, and a driven shaft. The conveyor belt can adopt various conveyor belts such as stainless steel mesh belt, Teflon, PVC, roller, chain plate, etc. according to the specific situation. (The material is determined according to the actual situation of the customer) The conveying speed can be continuously and steplessly adjustable within 0~6m/min.

3. Hot air drying, automatic temperature control heating system

The hot air drying and automatic temperature control heating system of the tunnel furnace is composed of a fan, a heating tube, a temperature sensor, and a temperature controller. The circulating air flows evenly blow the hot air from the heater to the conveyed workpieces, ensuring uniform hot air in the drying box, avoiding uneven heating of the surface of the object, and speeding up the water-free drying of the workpiece.

Four, electrical control system

It adopts automatic control by relay or power regulator, and all electrical components used in the equipment adopt accessories that meet international standards. Emergency stop buttons can be set at the inlet and outlet ends to prevent accidents and failure to stop in time and improve the safety performance of the equipment. The electric control cabinet is equipped with two-color lights to indicate the normal operation and failure of the equipment.
