Description

A multi-pipe air-supplied mist mist system

technical field

The invention belongs to the field of machinery, and in particular relates to a multi-pipe air-supplied mist mist system.

Background technique

The fog machine can atomize the liquid into very fine droplets and spray them out, and they can remain in the air for a certain period of time. At present, the mist mist machine has many uses, such as large-scale generally used for industrial dust removal, small-scale can be used for spraying pesticides, sterilization, warehouse humidification and so on.

At present, there are two common types of mist misters, one is the air-driven mist mister, and the other is the pulsed mist mister. The former uses high-speed airflow to break the droplets and sprays them out, and the latter uses the pulse principle to directly atomize the liquid and then spray it out. Among them, the pulse-type power is stronger but needs to use gasoline as power. The former only needs electric power, which is more convenient and environmentally friendly to use.

Most of the current air-supplied mist misters are throttled and atomized into droplets at the front end of the nozzle, and then further broken and atomized by the high-speed airflow in the air duct, and finally sprayed out under the action of the high-speed airflow. However, the flow rate of this method is small, the atomization intensity is low, and the atomization is not sufficient. When the spray size changes, part of the liquid often flows out without being atomized, causing waste, and the residual liquid will corrode the equipment for a long time.

FIG. 1 is a schematic diagram of the three-dimensional structure of the present invention.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and embodiments.

Example

As shown in FIG. 1, a multi-pipe type air-supplied mist mist system includes a fan 1, and the fan 1 is connected with an air duct 2 and an outer bobbin 7; the outer end of the air duct 2 is blocked, and the side wall is formed with a A number of first throttle nozzles 3; a number of annular liquid conduits 4 are installed along the axial direction outside the air duct 2, and a number of second throttle nozzles 5 are formed on the inner side wall of the annular liquid conduit 4; It is communicated with the water pump pipe 6;

The fan 1 communicates with the air guide pipe 2 through the throttle pipe 8 .

The first throttle nozzle 3 and the second throttle nozzle 5 are disposed opposite to each other. The annular liquid conduit 4 communicates with each other through a plurality of straight pipes 9 ; the straight pipes 9 are evenly arranged along the circumferential direction of the annular liquid conduit 4 . Preferably, the number of straight pipes 9 is four. The air guide pipe 2 and the annular liquid guide pipe 4 are arranged coaxially;

As shown in Figure 1, it is mainly composed of an outer bobbin, an annular liquid conduit, and an air conduit. The liquid conduit is fixed on the inner side of the cylinder wall, and the air conduit is fixed on the inner side of the outer bobbin or the liquid conduit through the brackets at the front and rear ends. tube. Compared with the common air-supplied mist mist system, the present invention adds multiple rows of liquid guide pipes and air guide pipes.

Specifically, the present invention is improved on the basis of the existing air-supplied mist mist system, and the improved catheter is a multi-row catheter. At the same time, the air duct was added. The water pump pipe at the end of the air duct is connected to the water pump to provide liquid medicine for the mist mist system. There is a powerful fan on the rear side to provide high-speed airflow for mist and jet.

On the inner side of the annular liquid conduit, there is an ordinary second throttling nozzle. When the liquid in the pipe is ejected by the pressure of the pump, due to the throttling effect, it will be ejected in the form of high-speed mist droplets, which will be released throughout the entire In the air duct; after the high-speed airflow given by the fan passes through the throttling duct to condense and throttle, part of it enters the annular space between the cylinder wall and the air duct, and part enters the air duct. Due to the throttling effect, the wind speed will increase. The air duct is opened on one side to form the first throttle nozzle. After the airflow enters from one side of the opening, the airflow in the pipe will be ejected along the radial first throttle nozzle (air hole) under the action of air pressure. , the wind speed will also increase.

The powerful fan can provide wind power to the air duct, so that the atomized droplets ejected from the throttle nozzle are broken and atomized into finer droplets and moved forward along the annular space between the cylinder wall and the air duct. . Ordinary air-supplied mist misters have only one annular liquid conduit at the front and no air conduit. Air ducts are designed and added here to utilize radial wind. The air flow in the air duct is sprayed out along the radial air holes on the pipe under the action of air pressure, which has a radial impact on the atomized droplets at the throttle nozzle, and promotes the atomization of the droplets, which will be sprayed from the throttle nozzle. The insufficiently atomized droplets are further broken up, and at the same time, the radial wind effectively avoids the flow loss caused by the adhesion of the atomized droplets to the outer wall of the guide air duct during the transmission process. In this way, part of the atomization work of the droplets is dispersed to the radial wind, so that the axial wind can be used more in pushing the water mist.
