Description
Technical Field
The invention belongs to the technical field of spray dust falling devices, and particularly relates to a nozzle angle adjusting device and a sprayer.
Background
Along with the development of environmental protection technology, the sprayer is widely applied. The dust settling principle of the sprayer is that high-pressure water is atomized through a nozzle and then sprayed into air containing various dust particles, atomized water drops interact with the dust particles, so that the dust particles become large and heavy, the sedimentation is accelerated, and the effect of purifying the ambient air is achieved.
Practice shows that the fog drops sprayed by the spray nozzle of the sprayer and the fog drops and the air flow have strong interaction, and the interaction can influence the range of the sprayer and the distribution of the grain size of the fog drops, thereby greatly influencing the dust settling effect of the sprayer. The nozzle installation angle can directly influence interaction between the mist drops and air flow, so that the performance of the sprayer can be greatly influenced. In reality, in order to obtain a good dust settling effect, the changes of different ranges and particle sizes are often required, and in order to adapt to different working conditions to obtain better performance, the angle of the nozzle is also required to be adjusted.
Many different approaches have been proposed to adjust the nozzle angle.
