BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for spraying lime milk for disinfecting livestock houses such as cow houses and pig houses.

[0002]

2. Description of the Related Art It has been known that lime milk obtained by dissolving quicklime in water is effective for disinfecting livestock houses, but conventionally, an airless coating machine or an air spray coating machine for spraying paint has been used. It was

[0003]

It is known that the higher the concentration of lime milk, the higher the bactericidal effect and the better the workability. However, the coating machine for spraying paint has a small nozzle diameter, so the viscosity is low I could only spray a fine coating.

For this reason, lime milk must be diluted with water to be used in a low concentration, has a low bactericidal effect, does not last long, requires a long time for spraying work, and prevents lime milk from clogging nozzles. There is a drawback that workability is poor.

[0005]

As a means for solving such a problem, the present invention provides a main nozzle for jetting lime milk with a diameter of 3 mm or more at the tip and for jetting pressurized air into the main nozzle. The spray gun facing the air nozzle was connected to the discharge port of the positive displacement pump via a hose.

[0006]

The present invention has the above-mentioned construction, and since the main nozzle has a large diameter, lime milk having a high concentration can be used without filtering, and the lime milk is sprayed in the form of large particles.

[0007] Therefore, the lime milk with a high concentration has a high temperature immediately after mixing with water and has a high viscosity, so that it does not easily run off even if it is applied thickly. Has a high bactericidal effect, and
The effect can be sustained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 is a positive displacement pump such as a mohno pump or a tubing pump driven by a motor 2 and having a hopper 3 for feeding lime milk obtained by dissolving quicklime in water.

Reference numeral 5 is a spray gun having a main nozzle 6, which has an ejection hole 7 having a diameter of 3 mm or more, and is connected to the pump 1 by a hose 4, which is connected to the main nozzle 6. An air nozzle 8 having a small-diameter ejection hole 9 facing the ejection hole 7 is inserted.

This embodiment has the above-mentioned structure. When lime milk is put into the hopper 3 and the motor 2 is started, the pump 1 is driven so that the lime milk in the hopper 3 passes through the hose 4 and the tip of the spray gun 5. In addition to being ejected from the ejection hole 7 of the main nozzle 6 and pressurized air ejected from the ejection hole 9 of the air nozzle 8, the lime milk is ejected in the form of large particles.
