Abstract
Description
Technical Field
[0001] The utility model relates to the field of underground smoke generating equipment, in particular to an underground smoke experimental device. Background Art
[0002] Underground fire safety is the top priority of safe production. Since the smoke sensing system is limited by the conditions in the coal mine, most of the smoke sensing experiments in the prior art are conducted through the test button on the smoke sensor. However, this test method cannot determine whether the smoke sensor is activated once smoke actually appears. In this regard, there are also special smoke generating devices in the prior art, but the combustion medium used by such equipment is generally mineral oil. It is very easy to have open flames during the experiment, and it is inconvenient to extinguish the fire. The equipment itself has great safety risks. There is currently a lack of corresponding solutions to the above problems. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an underground smoke experiment device with a simple structure, low smoke generation cost, especially low combustion medium smoke generation temperature, not easy to cause open flames and with a quick extinguishing device.
[0004] The device comprises a smoke generating barrel, wherein a partition is arranged inside the smoke generating barrel, and an electric heating wire is fixedly arranged under the partition;
[0005] A material delivery port is provided on the side of the smoke generating barrel, the material delivery port is arranged on the partition, and a closed air door is hingedly provided on the material delivery head;
[0006] A smoke outlet is provided on the smoke generating barrel;
[0007] A water pipe is also provided on the side of the smoke generating barrel. One end of the water pipe is connected to an external water source, and a nozzle is provided on the other end, that is, on the water pipe inside the smoke generating barrel.
[0008] The effect achieved by this is that the combustible material is put into the smoke generating barrel through the material delivery port. The combustible material mentioned here is preferably compressed biomass particles. The combustible material is sprayed to make it moist, and the partition part is heated by the electric heating wire. When the temperature in the barrel reaches a certain level, smoke can be naturally generated in the barrel without open flames. When in use, a metal hose and an induced draft fan can be connected at the smoke outlet to achieve smoke guidance. When extinguishing a fire, the fire can be extinguished by continuously spraying water with a sprinkler.
[0009] The beneficial effects of the utility model are: the utility model has a simple structure, low cost, low operating cost, and is especially safe to operate. A large amount of smoke can be generated without an open flame. At the same time, the smoke generation temperature is low, and the fire can be extinguished directly and quickly. The utility model is especially suitable for underground smoke sensing side vision, and has great market promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
