| titleOfInvention | A poisonous and harmful gas detection device for mine filling |
| abstract | The utility model relates to a toxic and harmful gas detection device for mine filling, which comprises a nitrogen bottle, a filling slurry preparation device, a filling slurry adding device with a valve, an electric heating sleeve, a gas identification device, a safety valve, a valve , Exhaust gas absorption device. The nitrogen cylinder is used to remove air from the entire device, the filling slurry preparation device includes a mixer and a safety valve, the filling slurry adding device is located on the upper part of the filling slurry preparation device, and the electric heating mantle is used for filling The heating of the pulp preparation device. The gas identification device is composed of 4 gas washing bottles for the identification of different gases. The tail gas absorption device is connected to the gas identification device through an air guide tube and a valve. The utility model simulates the mine environment, prepares the filling slurry, detects and identifies the gas that may be generated, and ensures the safety of workers in underground filling operations, and has the advantages of simple operation, convenient implementation and obvious effect. |
