Spray head and spraying system

Abstract

The invention discloses a spray head and a water spraying system. The spray head comprises a spray head body, runner holes are formed in the spray head body, and the runner holes comprise inlet parts,necking parts and outlet parts which are sequentially communicated; a movable rod is movably connected to the position, at the outlet part, of the spray head body, and the outer diameter of the movable rod is smaller than the aperture of the outlet part, so that water in the runner hole can be discharged outwards through the movable rod; wherein a flow guide hole is formed in the movable rod; a pipe joint is connected to the spray head body, is communicated with the flow guide hole in the movable rod, and can supply water to the flow guide hole in the movable rod; and the movable rod can movealong with water flowing through the pipe joint, so that the flow guide hole in the movable rod is communicated with the necking part. According to the spray head and the water spraying system, through reasonable structural arrangement, the self-dredging function of the spray head is achieved.

Description

technical field [0001] The invention belongs to the technical field related to water spraying, and in particular relates to a spray head and a spraying system. Background technique [0002] Nozzles are usually used to produce water. At present, in the process of coke preparation, enterprises need to pump water into a water tank with a height of tens of meters above the ground, and then spray the water in the water tank downwards with the nozzle to prevent the coke from being prepared. Coke dust, cooling. [0003] Among them, the above-mentioned nozzles used for spraying water have a large overall size, and the water in the water tank is inevitably mixed with granular impurities, so that the nozzles are prone to fouling in the flow channel holes of the nozzles during long-term use. , and can block the necking part of the flow channel hole of the nozzle from a large diameter to a small diameter. At present, in view of the above existing technical problems, the flow channel h...

AI Technical Summary

Problems solved by technology

Because there is a lot of dust in the environment where the nozzle is installed, and the height from the ground is tens of meters, it greatly increases the labor intensity of the workers, and there are certain hidden dangers to the personal safety of the workers. Dredging, its efficiency is poor, and it cannot meet the needs of enterprises
