Description

Technical Field

[0001] This utility model relates to the field of heat transfer oil heating and drying technology, specifically a heat transfer oil heating and drying conveyor line. Background Technology

[0002] With the continuous development of industrial production and the increasing demands for production efficiency, especially in industries such as coatings, plastics, food processing, and electronic component manufacturing, the requirements for material drying processes are becoming increasingly stringent. Traditional drying equipment often faces problems such as low drying efficiency, high energy consumption, large equipment footprint, and poor temperature control accuracy. These problems not only affect production efficiency but also increase production costs.

[0003] Thermal oil heating and drying conveyor lines are a common type of high-temperature drying equipment. They utilize thermal oil to transfer heat, achieving drying through heat exchange between the material and the oil. However, existing thermal oil drying conveyor lines still have certain limitations in some applications, mainly in the following aspects:

[0004] Existing thermal oil-heated drying conveyor lines suffer from problems such as long heating times and uneven heat distribution, resulting in slow material drying rates and failing to meet the demands for efficient drying in large-scale production. Especially when processing large quantities of high-humidity materials, excessively long drying times can lead to production bottlenecks.

[0005] Because the heat transfer process of heat transfer oil is affected by many factors such as flow rate, temperature control, and the design of the heat transfer oil circulation system, uneven temperatures in different areas often occur, affecting the drying effect. In some cases, the surface of the material may be over-dried while the inside remains moist, resulting in unstable drying quality.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a heat transfer oil heating and drying conveyor line. Utility Model Content

[0007] The purpose of this invention is to provide a heat transfer oil heating and drying conveyor line to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0015] A heat exchange plate is arranged below the mesh conveyor assembly and is connected to the heat transfer oil inlet pipe and the heat transfer oil outlet pipe to form a heat transfer oil circulation mechanism.

[0016] The diversion channel and the upper air duct connect the fan to the lower air hood and the upper air hood, and are used to evenly distribute the airflow.

[0017] A material turning mechanism is located above the mesh conveyor assembly and is used to adjust the material distribution.

[0018] As a preferred technical solution, the heat transfer oil circulation mechanism further includes a heat transfer oil connecting pipe disposed between the heat transfer oil inlet pipe and the heat transfer oil outlet pipe, and a heat transfer oil control valve is installed on the heat transfer oil inlet pipe, which is used to regulate the heat transfer oil flow rate and temperature.

[0019] As a preferred technical solution, the lower hood is equipped with an airflow regulating valve for controlling the airflow in the area.

[0020] As a preferred technical solution, the heat exchange plate has a multi-segment structure, and the segments are connected by oil pipes.
