Pressure-sensitive triggered spraying device for mine cars

Abstract

A pressure-sensitive triggered spraying device for mine cars is fine in use effect and comprises nozzles. The nozzles are communicated with electric ball valves through pipelines hermetically, the electric ball valves are electrically connected with a main controller through leads, and the main controller is electrically connected with a trigger device through a lead. The trigger device comprises a fixed protective box with an upwards opening, retaining plates are connected to the opening of the fixed protective box, an arch pressure plate is arranged in the fixed protective box, the highest position of the arch pressure plate is located above the opening of the fixed protective box, anti-pop pressure plates are connected to the edge of the arc pressure plate and arranged below the retaining plates, and springs are respectively fixedly connected between each anti-pop pressure plate and the bottom wall of the fixed protective box. A pressure sensitive sensor is fixedly mounted in the fixed protective box and electrically connected with the main controller through a lead, and a trigger button is fixedly connected to the lower side of the arch pressure plate and located above the pressure sensitive sensor to correspond to the pressure sensitive sensor.

Description

technical field [0001] The invention relates to a spray dust suppression device for mines, in particular to a pressure-sensitive mine car trigger sprinkler device. Background technique [0002] At present, the main roads in each mining area of ​​each coal mine use atomized full-section automatic purification water curtains to reduce dust. The main roads in the current mining areas are mainly installed with manual normally open purification water curtains and infrared automatic dust reduction sprays, mainly through the use of dust-proof water. The static pressure instantly atomizes the water high-pressure jet liquid into extremely small atomized droplets to capture the dust in the air flow of the roadway. Due to pedestrians and driving in the mining area, the purification water curtain spray and infrared purification water curtain are often opened due to multi-directional reasons such as man-made and facility failures, and the use effect is not good. The dust on the surface o...

AI Technical Summary

Problems solved by technology

Due to pedestrians and driving in the mining area, the purification water curtain spray and infrared purification water curtain are often opened due to multi-directional reasons such as man-made and facility failures, and the use effect is not good. The dust on the surface of the mine car cannot be thoroughly washed. There is a certain bottleneck in the dust control generated during transportation or coal (gangue) vibration and crushing
