Description

Technical Field

[0001] This invention relates to the field of port dust suppression technology, and in particular to a heat tracing dust suppression device for port conveyor belts suitable for low-temperature environments. Background Technology

[0002] Belt conveyors, as an important material conveying equipment, are widely used in various industries such as mining, metallurgy, chemical industry, and ports. However, during the material feeding process at the connection of the belt conveyor due to the height difference, a large amount of dust is generated due to the friction between the material and the belt, the collision between material particles, and the interaction between the material and the air. This dust not only seriously affects the working environment and threatens the health of operators, but may also lead to equipment failure and reduce production efficiency. In the past, materials were poured directly from the head of the high-speed belt conveyor onto the ground, and the acceleration due to gravity generated dust, polluting the environment and posing hidden dangers to equipment maintenance and operational safety.

[0003] Existing dust suppression devices are inadequate for low-temperature environments, and water pipes are prone to freezing. Installing external heat tracing devices on the water pipes is cumbersome and complex; using a winding method increases resistance; excessively long pipelines can lead to overheating at the front and poor heating at the rear; and with single-line straight laying, heat concentrates on one side of the pipe, resulting in uneven temperature distribution across the pipe cross-section (the lower half dissipates heat quickly and may freeze). Heat transfer relies on fluid flow itself, increasing the risk of cold spots in static fluid scenarios. Single-line laying cannot cover the entire circumference of the pipe, and the unheated side is prone to freezing in cold environments (especially horizontal pipes on the ground). For extremely cold regions or intermittent water flow pipelines, additional heat tracing tape is required (e.g., double-line symmetrical laying), increasing costs. Summary of the Invention
