The electric heating tube is a tubular electric heating element, which is composed of a metal tube spiral resistance wire and crystalline magnesium oxide powder. The high-temperature resistance wires are evenly distributed in the stainless steel seamless tube, and the gaps are filled with thermal conductivity, which has high thermal efficiency and uniform heat generation. It is transferred to the heated part or the air to achieve the purpose of heating.
Main technical difficulty: Although the stainless steel electric heating body is a relatively mature technology, the material of stainless steel has its particularity, and the welding process is also more complicated. Therefore, when designing the structure of the heating body, special attention should be paid to this aspect. At the same time, relevant tests must be done to verify the reliability of this design, so as to ensure the use effect of the product and give full play to the advantages of stainless steel heating pipes.
Features:
1. Most of the hot air circulates in the box, with high thermal efficiency and energy saving.
2. Using forced ventilation, there is an adjustable air distribution board in the box, and the material is evenly dried. The heat source can be steam, hot water, electricity, far infrared, and a wide range of choices.
3. The whole machine has low noise and stable operation. Temperature automatic control, easy installation and maintenance.
4. It has a wide range of applications and can dry various materials. It is a general drying equipment.
