[0026] Working principle: The utility model is a kind of fire-preventing device for coal mine goaf with water mist. During use, the sealing cover 3 is opened to pour the mixed inhibitor into the inner cavity of the storage box 1. When fire prevention work is needed in the coal mine goaf, the water pump 4 is started by an external power supply. The water pump 4 draws the inhibitor inside the storage box 1 from the water pumping pipe 5, and then reaches the inner cavity of the filter cartridge 7 through the water delivery pipe 6. As the amount of inhibitor inside the filter cartridge 7 increases, the liquid level height becomes higher, the inhibitor is filtered by the filter screen 23, and then the inhibitor is discharged from the drain pipe 24, and finally the inhibitor is sprayed from the nozzle 26. The filter screen 23 can filter out the undissolved block inhibitor raw materials to avoid the undissolved block inhibitor raw materials clogging the nozzle 26, thereby ensuring the normal spraying of the inhibitor, thereby ensuring the normal progress of the fire prevention work;

The cleaning work of the filter screen 23 is also carried out along with the transportation of the inhibitor. There is no need to clean the filter screen 23, which is more convenient to use. The undissolved block inhibitor raw materials fall into the inner cavity of the threaded barrel 10 under the action of gravity. When the spraying work is stopped, the threaded barrel 10 is unscrewed to clean the undissolved block inhibitor raw materials in the inner cavity of the threaded barrel 10.
