Adjustable conical ring curtain dust suppression spray head

Abstract

An adjustable conical ring curtain dust suppression spray head comprises a spray nozzle shell, a Venturi structure inner pipe, a water pipe connector, a water flow disturbance device, a cyclone, a spray nozzle head and a spray nozzle head check block. The spray nozzle shell is a hollow shell, the Venturi structure inner pipe is coaxially arranged in one end of the spray nozzle shell, and the waterpipe connector is arranged on the side face of the spray nozzle shell and communicates with the interior of the spray nozzle shell. The water flow disturbance device is arranged in the water pipe connector. The other end of the spray nozzle shell is connected with the spray nozzle head, and the cyclone is arranged at the position, close to the spray nozzle head, in the spray nozzle shell. The spray nozzle head check block is conical, a conical inner cavity is formed in the end of the spray nozzle head, and the spray nozzle head check block is arranged in the conical inner cavity. The multi-time atomization and mixing adjustable spray head can control the spraying amount under the conditions of different construction occasions, different air temperatures, different air speeds and differenthumidity, can improve the atomization rate, is uniform in atomization, is relatively good in water-saving effect, and has very strong adaptability.

Description

technical field [0001] The invention belongs to the field of mechanical nozzle equipment, and in particular relates to an adjustable cone ring curtain dust suppression nozzle. Background technique [0002] Nowadays, nozzles play an important role in all aspects of social life, such as vehicle fuel injectors, bathroom showers, spray nozzles, high-pressure water guns, dust suppression water curtain heads and so on. Especially for dust suppression water curtain nozzles, as the country pays more and more attention to environmental protection, a lot of dust will be generated in many engineering constructions, and the construction period will be seriously affected. Therefore, the application market of dust suppression nozzles is very wide. But in practice, because the dust particles are relatively small, it is very easy to change with the flow of air. How to better atomize water or dust suppression mixed liquid and better form a closed water mist curtain wall is particularly impor...

Problems solved by technology

[0003] Ordinary nozzles are generally cylindrical hole nozzles. The spray distance and atomization angle are adjusted by pressurizing, increasing the flow rate or adjusting the size of the nozzle hole to suppress dust. Such nozzles not only consume a lot of ener
