Dongfeng Tianjin Railway Dust Suppression CarTop configurationThe tank body is a 10 cubic circular tank with anti-corrosion measures inside, including front flushing, rear spraying, side spraying, anti-aircraft gun, and dust suppression spray rod (with rotating and telescopic function). The spraying rod is 3.5-4.5 meters above the ground, and the rear platform is equipped with an 8KW auxiliary generator set. Two 1.5KW electric motors (with mixing function) are added inside the tank body. The tank body is painted with white on the top and blue on the bottom, and the platform and spraying rod are blue. The remote control operates the spray rod to rotate up, down, left, and right. The platform is widened by 20CM compared to the previous vehicle, and the electrical control box is installed on the rear platform.

The whole vehicle adopts fully intelligent electronic control operation, including vehicle spray system, mixing function, and rotating arm function. All functions of the Zhire function bicycle flowmeter, except for the chassis and water tank self suction and self discharge, are powered by the on-board auxiliary generator set, and an external power connector sleeve is reserved in the distribution box.

The sprinkler system is equipped with a single flow meter (used to measure the amount of dust suppressant sprayed on each train skin), and a hook stop spray system (contact induction spray, stopping spray between two train skins) is installed, with vehicle number recognition and recording functions. The whole vehicle spray system, single vehicle flow meter, and vehicle number recognition recording function are all connected and reflected on the intelligent computer screen.

When the spraying principle is in standby mode. The spray arm of the dust suppression spray car for coal transportation on the Dongfeng Tianjin Railway is located above the maintenance and recovery platform parallel to the railway tracks; When in working condition, the locomotive with a pantograph passes by. Rotate the spraying arm to a position perpendicular to the carriage, adjust the height, and lower it to 30cm above the train carriage. Use the vehicle identification system to detect the vehicle model and number. Under the control of the PLC, the spraying drum will start spraying according to the principle of stopping spraying with hook gear; After the spraying is completed, the system switches to the cleaning mode to clean the pipeline and nozzle, and the cleaning solution flows back to the mixing tank. When the vehicle speed is within the range of 05-1.0km/h, the spray control system can achieve uniform coverage of coal transport vehicles and ensure that it does not affect the safety and normal operation of locomotives and vehicles
