Description

Technical Field

[0001] The utility model relates to the field of railway dust suppression, in particular to a counter-spraying railway dust suppression spraying device. Background Art

[0002] Railway transportation is one of the important modes of transportation in my country. During the transportation of coal, the relative movement of airflow and wind can easily cause coal dust to fly everywhere, which not only wastes coal resources but also causes great pollution to the environment along the railway. Therefore, dust suppressants are sprayed on the upper layer of coal during coal transportation.

[0003] Dust suppressants are composed of a new type of multifunctional high molecular polymer. The cross-linked molecules in the polymer form a network structure, and there are various ion groups between the molecules. Due to the high charge density, it has a strong affinity with the ions, and can quickly capture and firmly adsorb particulate dust through coagulation and adhesion. After drying, it can solidify into a film on the dust surface, so it has a strong dust suppression and dust prevention effect.

[0004] There are many types of dust suppression spraying equipment in the prior art. Among them, there is a pair-spraying dust suppression spraying device, which is generally fixed on both sides of the railway with a fixed spraying angle. During actual coal loading, the coal is located at different heights inside the carriage. At this time, when the fixed spraying angle is used to spray coal surfaces at different heights, there will be a spraying dead angle. For example: the initial setting state of the spraying angle is to spray the coal surface flush with the height of the carriage. If the middle height of the coal loading is higher than the height of the carriage, there will be a gap between the two spraying areas and the contact position of the coal, resulting in a spraying dead angle. Based on this, the utility model proposes a pair-spraying railway dust suppression spraying device to increase the spraying angle and improve the spraying range. Utility Model Content
