In contrast, conventional dual fluid mist guns have improved on the basis of air-fed sprayers. The single-fluid spray ring which sprays water on the basis of the air-assisted sprayer is replaced by a double-fluid spray ring which is used for water and air, compressed air is introduced into the spray ring when the spray ring is connected with pressure water in the using process, and secondary atomization is carried out.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the process of realizing the scheme, the inventor finds that the existing air-assisted sprayer or the traditional double-fluid fog gun has the problem of relatively large water consumption, and also finds that the two devices have large appearance and volume and are usually required to be arranged on a tower platform with a certain height, which can bring about some inconvenience on some fields. In addition, the pitching amplitude mechanism of the wind barrel is complex, and the installation is likely to be slightly complicated. And the use and maintenance costs of the equipment are also high, requiring periodic maintenance and servicing to ensure its stable and efficient operation. Therefore, the inventor specially designs the water consumption so that the total spray amount of the upper half part is larger than that of the lower half part, and the water consumption is greatly reduced while the atomization effect and the range are ensured. Further, an axial flow fan with large air quantity and small volume is selected, so that the volume of the whole double-fluid fog gun is smaller, and the space occupation is reduced; and the pitching amplitude variation mechanism is simplified, and the maintenance and the repair are convenient.

Embodiments of the present utility model will be described in detail below with reference to the attached drawings in the drawings of the embodiments of the present utility model.

Example 1

The total amount of the upper part of the spray is larger than that of the lower part of the spray, and the spray can be realized by adjusting the spray flow or performing the density setting on the spray seat 41. When the spray flow rate is adjusted, the spray seats 41 can be uniformly arranged along the circumferential direction of the air inlet ring, the interval spaces among the spray seats 41 are the same, and the flow rate of the nozzles 42 is limited, and the flow rate of the single nozzle 42 in the upper half is larger than that of the single nozzle 42 in the lower half, so that the total spray amount in the upper half is larger than that in the lower half. When the spray seat 41 is arranged in a sparse and dense manner, the spray seat 41 is arranged in a non-uniform manner, namely, the spray seat 41 in the upper half is more installed, and the spray seat 41 in the lower half is less installed, so that the total spray flow rate in the upper half is greater than the total spray flow rate in the lower half. The denser spray seats 41 of the upper half and/or the thinner spray seats 41 of the lower half can be uniformly distributed or unevenly distributed when designed. The distances between the upper half spraying seats 41 are the same, the distances between the lower half spraying seats 41 are the same, but the distances between the upper half spraying seats 41 and the lower half spraying seats 41 are different; the non-uniform distribution, i.e. the intervals of all the spraying seats 41 are different, for example, the setting intervals of the spraying seats 41 are gradually increased along the top-to-bottom direction, and the spraying flow is gradually decreased in a gradient. It should be noted that, the two ways of adjusting the spraying flow and setting the number of the spraying seats 41 may be arbitrarily combined according to the requirement, so long as the total amount of the upper part of spraying is satisfied to be greater than that of the lower part of spraying, and no description will be given here.
