Description

The present invention relates to an agitating fan with a fine fog device intended to improve an agitating fan used for agriculture, livestock production, or the like.

  Conventionally, the structure which injects the fluid conveyed through piping to this kind of stirring fan from one nozzle can be considered. The applicant also manufactured an experimental machine based on this concept and tested it in the factory. As a result, it was found that there was a tendency to flow down at about 5 m, and a sufficient diffusion effect was not achieved. In view of such a situation, as a result of investigating prior literatures, the following ideas have been searched, and the outline thereof will be described below.

  This document (1) is “Mist fan and mist fan kit” of utility model registration No. 3068525. In this device, a ring-shaped liquid feed pipe having a size corresponding to the blade diameter of the blower fan is arranged on the front face of a blower fan installed in a greenhouse, greenhouse or barn, and an appropriate number of jet nozzles are provided in the liquid feed pipe. The mist atomized from this jet outlet is diffused in the greenhouse, greenhouse or barn by wind pressure, and is cooled using disinfection or latent heat of vaporization, and inside the greenhouse, greenhouse or barn for agriculture. It is intended to realize disinfection and cooling of air with simple equipment.

  Reference (2) is a “moisturizing spray device” disclosed in Japanese Utility Model Laid-Open No. 7-9457. In this device, a fan that is rotated by a motor is provided in a ventilation cylinder that is open at both ends, and a plurality of spray nozzles are provided in the air blowing direction of the fan and in the periphery of the outlet of the ventilation cylinder. The sprayed fine mist is included in the air blown from the fan, and is sprayed at a high speed to distant. The concrete placement surface by the RCD method in the dam construction is extensively covered for curing. It is intended to provide a spraying device for moistening that can be employed as a moisturizing means for applying fog.

As shown in FIG. 3, all the nozzles 11 are inclined in the axial direction (axial direction of the impeller 4), thereby converging in the injection (spraying) direction and generated by the impeller 4. As described above, while promoting atomization of the jetted fluid, the fine mist can be distant and the fine mist can be diffused. Of course, the direction of the nozzle 11 can be changed in whole and / or in part, and is selected according to the climate and / or the crop (livestock), the mounting position, the form of the house H (livestock), and the like. As described above, according to the present invention, the fluid ejected from the nozzle 11 is instantly atomized, and is guided by the wind blown from the end portion in the blowing direction of the casing 6 and diffused over a wide area. There is.

  The pipe 10 is supported by a plurality of attachment bodies 13 fixed to the casing 6 with an appropriate interval, and the vibration of the casing 6 is not transmitted to the pipe 10, so that uniform injection from the nozzle 11 is intended.

  Reference numeral 20 denotes a bell mouth provided between the guard 5 and the casing 6, and the wind generated by the impeller 4 is smoothly blown to the casing 6 and contributes to the generation of this wind.

  In the figure, reference numeral 21 denotes a pipe for supplying a fluid to the pipe 10 and is connected to a tank (not shown) attached to a tank and / or a stirring fan. Although not shown, it is also possible to provide a tank directly on the stirring fan.
