Description

Technical Field

[0001] This utility model relates to the field of directional drill pipe processing technology, specifically to a surface treatment device for directional drill pipe processing. Background Technology

[0002] Directional drill pipes play a crucial role in drilling operations in fields such as oil, natural gas, and geothermal energy. To improve the service life and performance of drill pipes, appropriate surface treatment is essential. Surface treatment can enhance the drill pipe's corrosion resistance, wear resistance, and fatigue strength.

[0003] Drying the surface is an important step in the production of directional drill pipes. It not only helps improve product quality but also ensures the smooth progress of subsequent processes. The common drying method is hot air drying, which uses a blower to blow heated air onto the surface of the workpiece, using the high temperature air to remove moisture and accelerate the evaporation process.

[0004] However, in most common drying equipment, the distance between the hot air duct and the directional drill rod is fixed. This fixed distance results in uneven hot air distribution, especially when processing directional drill rods of different lengths or shapes. Some parts may not be heated enough, while others may be overheated. This leads to inconsistent drying results, with some areas still damp while others are over-dried, affecting the quality and consistency of the final product. Utility Model Content

[0027] The drying hood 201 is fixedly installed above the top of the conveyor belt 101, forming a closed or semi-closed space to concentrate heat and improve drying efficiency. The chute 203 is located on the front and rear sides of the inner wall of the drying hood 201, guiding the sliding of the horizontal moving plate 204. The horizontal moving plate 204 slides horizontally within the chute 203 to adjust the air outlet position and ensure uniform hot air distribution.
