Abstract

PURPOSE:To make available the titled device for the spray of ceiling, by arranging the same such that a compressed air is blown-off from inside a nozzle to scatter away water drops for thereby eliminating the drip of water from the ceiling. CONSTITUTION:Upon an operation being started, a solenoid valve 24 is opened for discharging a compressed air which then is supplied via a conduit 10 to a nozzle 5. The compressed air enters into the nozzle 5, pushing a shut-off valve 15 and a spring 16, and passes through a strainer 19. The air is finally discharged out of a nozzle bore 14. Subsequently, a solenoid valve 23 is opened for supplying to a conduit 4 a high pressure water which enters into the nozzle body 5, similarly pushing a shut-off valve 17 and a spring 18. At the start of operation, the water which is pumped out from a water pump unit 1 has not a pressure sufficiently high to be atomized. There is, however, a flow of high pressure air inside the nozzle body 5, and therefore the water can be blown-off from the nozzle bore 14 in a foggy state, together with the air without the chance of water being collected to drip.

Description

DETAILED DESCRIPTION OF THE INVENTION At the start of this project, water is uniformly sprayed near the ceiling of the bead in foundries and forging factories where a lot of dust and heat are generated. This technology cools the air using the latent heat of evaporation of water, adds moisture to the dust floating in the air, makes it heavier, and makes it fall quickly, reducing dust and improving the working environment. be.

In conventional water sprayers, the water pressure is low when the water pump starts or stops, so the water does not form streaks and may fall into water droplets, which could contaminate the product. However, it was inappropriate for the singing chamber on the ceiling and could not be used. In order to prevent these droplets from falling, the uninvented Kuihesogeki uses compressed air to blow out water droplets by using a specially improved pEXh nozzle to blow out the compressed air from inside the nozzle. Because it can eliminate flying and dripping,
It can be used for the purpose of issuing →.

The present invention has been made in view of the above points, and will be described in detail below with reference to Examples.

Figure 1 is an overall view, in which the water tank unit 1 is equipped with an electric motor 2,
It is formed by a water pressure pump 6 connected to the electric motor 2.
The high-pressure water is driven by the solenoid valve 25, passes through the special pipe 4, reaches the nozzle 5, and is sprayed as 522.

On the other hand, six air compression units and electric motors 7 are driven to store the air taken in by the air compressor 8 in a high-pressure tank 9 under high pressure. When starting or stopping this equipment, turn on the solenoid valve 24 and release the compressed air.
It passes through gi10f and reaches the nozzle 5, mixes with water inside the nozzle 81≦, blows out from the nozzle opening at high speed, and atomizes, thereby preventing droplets.

In this operation, a temperature thermometer 16 and a humidity switch 12 are installed in the factory using the control panel 11, and the operation can be performed in accordance with the work cycle of each factory.

FIG. 2 is a detailed sectional view of the nozzle 5 showing the internal structure, which will be explained in accordance with the operation. At the start of operation, compressed air is first opened by opening the solenoid valve 24 and sent through the dedicated pipe 10 to the nozzle 5. Pressure? ! Air is supplied through check valve 15 and/or
<Press 16, enter inside nozzle 5, and press strainer 1♀? - and blows out from the nozzle port 17+. Next, the electromagnetic force 23 is applied to send high pressure water to the private pipe 4, and the high pressure water also pushes the check valve 17 and spring 18 and enters the inside of the main body 5. At the time of starting operation, the pressure of the water sent from the water pump unit 1 is high enough to atomize it, but since high-pressure air is already flowing inside the nozzle body 5, the nozzle can flow without getting water involved and dropping. It can be blown out from the mouth 14 in a streaky manner along with solid air. After the water pressure has increased to the point where it can be converted to i, the solenoid valve 24 of the air compression unit 6 is opened to stop the air supply and operation can be continued. When the operation is stopped, the solenoid valve 2A of the air compression unit 1) is opened, and the compressed air passes through the dedicated pipe 10 and reaches the nozzle 5.

Compressed air presses the check valve 15 and spring 16 to enter the nozzle 5, and when the pressure becomes sufficiently high, the solenoid valve 23 of the water hive unit 1 is closed to stop sending high-pressure water, and at the same time, the end of the dedicated pipe 4 is closed. Solenoid valve 25' installed in Open to release pressure. However, the residual pressure of high aqua regia remains in the conduit Δ, and the water inside the conduit 4 presses the check valve 17 and spring 18 to gradually reduce the pressure and flow into the nozzle body 5. Compressed air is already at high pressure inside the main body 5 and is blown out from the nozzle port 14, and the water that has flowed into the nozzle main body 5 is completely entangled in the compressed air and flows through the nozzle port 1A to the bed 22. Since it can prevent water from blowing out and dripping, it can be safely used as a cooler in factories or as a water inlet device for removing dust.
