Calcium carbide illuminating lamp

Abstract

The invention relates to a calcium carbide illuminating lamp. The lamp comprises a water barrel and a calcium carbide barrel which are detachably connected, wherein the water barrel is connected at the top of the calcium carbide barrel; a gas pipe penetrating through the wall of the water barrel and communicating with the calcium carbide barrel is arranged in the water barrel; a fire nozzle is connected onto the gas pipe; a water inlet is formed in the top of the water barrel; a plurality of water outlets are formed in the bottom of the water barrel; and the lamp further comprises an adjusting device, and the adjusting device penetrates through the inside of the water barrel, extends into the calcium carbide barrel, controls the water outlets to be opened or closed and stirs calcium carbide simultaneously. According to the lamp, the adjusting device is arranged, so that the opening size of the water outlets 12 can be adjusted, the amount of water entering the calcium carbide barrel can be controlled, the yield of acetylene can be controlled, and the condition that bubbles are produced due to the too high yield of acetylene is avoided; meanwhile, calcium carbide is stirred while the amount of the water entering the calcium carbide barrel is adjusted, accordingly, calcium carbide can make full contact with water for a reaction, and the lamp is convenient to operate.

Description

technical field [0001] The invention relates to a lighting device, in particular to a calcium carbide lighting lamp. Background technique [0002] The luminous principle of calcium carbide lamp is to use calcium carbide (chemical name is calcium carbide, the appearance is gray, brown yellow, black or brown block solid, which is the basic raw material of organic synthesis chemical industry) to react with water to generate acetylene, and acetylene burns and emits light after being ignited. [0003] Because calcium carbide lamps are economical, have good lighting effects, can be adjusted in brightness, do not need to be charged, are convenient to hang during operation, and can also measure the oxygen content in mines, so they are safe to use. At present, they are used in many private mines and small and medium-sized state-owned collective mines, especially non-ferrous metal mines. Carbide lamps are still widely used in metal mines. However, the structure of the current calcium...

AI Technical Summary

Problems solved by technology

However, the structure of the current calcium carbide lamp is relatively simple, and the amount of water intake cannot be controlled. If too much water enters a large amount of acetylene, the gas will be discharged from the connection between the water cylinder and the calcium carbide cylinder, resulting in bubbling.

[0004] In addition, after water enters the calcium carbide cylinder, it mainly reacts with the calcium carbide on the surface, while the calcium carbide below the surface cannot fully contact with water, resulting in incomplete reaction.
