Embodiment Construction
[0033] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0034] The invention provides a spray device. The spraying device includes a nozzle and a fan, and the liquid sprayed from the nozzle is ejected in the form of mist through the fan.
[0035] Such as Figure 8As shown, in the embodiment of the present invention, the fan includes a hub and a plurality of blades, and the plurality of blades are arranged at intervals along the circumference of the hub.
[0036] In the present invention and the embodiments of the present invention, the spraying device is a fog cannon.
[0037] In the embodiment of the present invention, in order to solve the problems in the prior art that the shape of the blade is unreasonable and the air flow is poor, resulting ...

The invention provides a blade, a fan with the blade, a spraying device and a blade determining method. The blade comprises a suction surface provided with a suction surface blade root profile and a suction surface blade top profile, and a pressure surface provided with a pressure surface blade root profile and a pressure surface blade top profile. The suction surface blade root profile, the suction surface blade top profile, the pressure surface blade root profile and the pressure surface blade top profile are all oval curves, the circle centers of the oval curves of the suction surface blade root profile and the pressure surface blade root profile are located on the same side of the blade, and the circle centers of the oval curves of the suction surface blade top profile and the pressure surface blade top profile are located on the same side of the blade. The pressure surface blade root profile and the pressure surface blade top profile are both inwards-concave curves facing the inside of the blade, and the suction surface blade root profile and the suction surface blade top profile are both outwards-convex curves facing the outside of the blade. By means of the technical scheme, the problems that in the prior art, a blade is not reasonable in shape and poor in airflow flowability and consequently an axial flow fan is large in noise and low in operation efficiency can be solved.
Description
technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a blade, a blower fan and a spraying device with the blade, and a method for determining the blade. Background technique [0002] The scope of smog outbreaks is rapidly expanding, and haze control and dust reduction have become urgent problems for the whole society. At present, the equipment used to control haze and reduce dust mainly includes dust suppression vehicles and fog cannons. The main parameters affecting the performance of the fog cannon include operating noise, range and operating efficiency. [0003] The fog cannon includes an axial flow fan, and the blades of the axial flow fan have a suction surface and a pressure surface arranged oppositely. In the prior art, the shape lines of the tip of the blade on the suction side and the tip of the pressure side, and the shape of the root of the blade on the suction side and the root of the pressure side are ...
