Description

Technical Field

[0001] This application relates to the field of dust suppression technology in coal transportation, and in particular to a spray dust suppression device for coal transportation. Background Technology

[0002] With the increase in bulk coke transportation volume, in order to meet environmental protection requirements, dust suppression is required at the unloading site when the goods are unloaded at the port. The traditional dust suppression method is to use mobile fog cannons to spray the working surface during the unloading period. However, the spraying distance and angle are difficult to control due to the influence of wind direction and wind force, resulting in poor dust suppression effect and low efficiency.

[0003] The existing dust suppression spraying system does not take into account measures for normal operation under extremely cold conditions, which is not conducive to the normal operation of the system under extremely cold conditions.

[0004] The existing dust suppression spray system is not well-designed in terms of safety. There are insufficient safeguards for its normal operation under poor lighting conditions, making it difficult to guarantee the safety of the system and personnel.

[0005] When multiple vehicles are operating simultaneously, without multiple fog cannons working together, the vehicles need to queue up to unload, and the fog cannons are in a continuous state of operation, resulting in a large amount of water consumption and a waste of water resources. Utility Model Content

[0006] The problem this invention aims to solve is that traditional spraying operations are easily affected by the environment, resulting in poor dust suppression, low efficiency, serious water waste, and insufficient safeguards for normal operation under extremely cold conditions and poor lighting conditions. To address these issues, the invention improves the spraying method by using multiple spray holes for concentrated spraying, incorporating detection components, coordinating with a solenoid valve control device for start / stop, heating the water source in the pipeline, installing lighting and anti-collision bollards before and after the device, and constructing drainage ditches to collect wastewater, which is then filtered and recycled in a collection well. This achieves automatic and efficient operation, ensuring the device does not freeze under extremely cold conditions, protecting the device and personnel from damage under poor lighting conditions, and is energy-saving and environmentally friendly.

When the lighting conditions are poor, the lighting lamp 5 will be turned on to provide illumination. The anti-collision stone blocks 6 arranged on both sides of the device along its length serve as guides and anti-collision warnings, effectively protecting the device. When the ambient temperature is low, the heating cable 104 will be activated to heat the No. 3 water supply pipe 103. The heat is transferred to the water in the No. 3 water supply pipe 103 to keep it in a non-freezing state, giving the device strong environmental adaptability, safety, high efficiency, and environmental friendliness.
