Description

Water compressor of air compressor {THE MOISTURE REMOVE APPARATUS FOR AIR COMPRESSOR}

The present invention is applied to an air compressor applied to a sandblaster for removing various oxides and investment materials attached to the surface of a prosthesis after demolding in various air washing or gas blockers or dental prostheses, or to give a surface finishing effect and gloss effect. It relates to a water removal device that is.

More specifically, the exhaust air is injected through a separate long coil cooling pipe without directly injecting the air generated from the air compressor, but an air suction fan is placed in the upper center of the coil pipe so that the outside air is continuously contacted with the coil cooling pipe. By inducing to circulate to cool the temperature of the compressed air flowing through the coil cooling tube in the state formed higher than the outside temperature in the air compressor to match or close to the outside air.

At this time, the condensation phenomenon caused by the temperature difference between the object or the injection nozzle in contact with the injection air and the injection air is prevented to prevent moisture from being contained in the injection air.The structure is simple, easy to maintain, The savings were to improve practicality.

In general, an air compressor is a device that sucks air in the atmosphere, compresses the air to a predetermined pressure, and supplies compressed air to a related device. The compressed air is kept at a relatively high temperature compared to the outside air.

When such hot compressed air exits the air compressor and is exposed to the outside and passes through a spray nozzle having the same temperature as the outside air or contacts a device or an object such as the outside temperature, the temperature of the nozzle or the object is relatively low compared to the compressed air. The relative humidity of the compressed air increases due to the temperature variation, resulting in condensation.

As a result, water is contained in the sprayed air, which causes water to penetrate the device, causing a breakdown, or in the case of sandblasting, the processed particles mix and aggregate with the water to block the hole of the spray nozzle or reduce the dispersion force of the processed particles. Problems such as reducing the effect occur.

Therefore, in view of the above problems, the compressed air generated in the air compressor requires a separate cooling process to prevent condensation.

For this purpose, conventional devices such as an air filter, an adsorption type air dryer, a refrigeration air dryer, etc. have been separately installed and installed, but this impedes the blowing force of air or the structure is very complicated and the price is very expensive, thereby reducing the practicality.

The present invention has been made to solve and solve the above problems,

An object of the present invention is to cool the temperature of the compressed air flowing through the coil cooling tube to match or close to the outside air in a state where the air compressor is formed higher than the outside temperature, thereby reducing the temperature difference between the object or the nozzle in contact with the injection air. It is to prevent the condensation caused by.

Therefore, to prevent the inclusion of water in the injection air to simplify the structure, easy to maintain and to provide a water removal device of the air compressor that can improve the practicality by reducing the manufacturing cost,

Hereinafter, the configuration of the present invention in detail based on the accompanying drawings.

Figure 1 is a perspective view showing an example of the configuration of the device of the present invention, Figure 2 shows a cross-sectional view showing the structure and operation of the present invention,

The present invention is connected to the air discharge pipe (AC ') of the known air compressor (AC) and the coil cooling pipe 10 of a predetermined length wound in a spiral to extend the length of the air passage;

The coil cooling pipe 10 is fixedly installed in any place through the bracket 21 in a state accommodating therein, and the plurality of heat sinks 22 are radially composed of a material having good thermal conductivity to facilitate heat exchange. An external air guide tube 20 formed in a penetrating state;

The air suction fan is fixedly installed at the upper center of the outside air guide pipe 20 to forcibly introduce outside air to the bottom of the outside air guide pipe 20 to impart an air cooling effect to the coil cooling pipe 10 located therein. 30;

A small amount of condensed water that may be present in the coil cooling pipe 10 and applied to the air transfer pipe 40 exposed to the outside of the outside air guide pipe 20 while being integrally connected to the coil cooling pipe 10. A condensation receiver 50 for storing and discharging;

In the state of being integrally attached to the surface of the outside air guide tube 20 is electrically connected to the air suction fan 30 is installed to detect the temperature of the coil cooling tube 10 to control the operation of the air suction fan 30 It is to include a temperature sensor 60 for each.

Referring to the operation of the present invention configured in this way in detail as follows.

The present invention is fixedly installed through a plurality of brackets 21 installed in the air guide pipe 20 in any place in a state connected to the air compressor (AC) as shown in FIG. Various nozzles for the injection of compressed air may be installed, and in the case of a sand blaster, a flexible hose applied with an air gun is connected to the end.

The air compressed by the air compressor (AC) to maintain a high temperature is introduced into the coil cooling tube 10 inside the outside air guide tube 20 through the air discharge pipe (AC ') and at the same time the temperature sensor 60 is coil cooling If the temperature deviation of the tube 10 is small and there is no room for condensation, the air suction fan 30 is not operated. On the other hand, the temperature difference of the coil cooling tube 10 is higher than that of the compressed air. If there is room for condensation due to low temperature in a large state, power is applied to operate the air suction fan 30.

When the air suction fan 30 is operated, as shown in the arrow, the air is sucked up from the bottom of the air guide tube 20 and discharged to the upper part continuously, and the thermal conductivity of the guide tube 20 is increased. The radial heat dissipation tube 22 made of a good material expands the contact area with the atmosphere, so that heat exchange is smoothly performed.

As such, the relatively low temperature outside air continuously circulates in contact with the cooling coil pipe 10 through which high-temperature compressed air flows, and is circulated by heat exchange in the heat sink 22 formed in the guide tube 20. 10) is cooled, and the compressed air flowing therein is also cooled to cool to the same or close to the outside air to prevent condensation by zero or minimizing the temperature deviation.

At this time, when the temperature of the sensed coil cooling tube 10 is cooled to the same or set range as the outside air, the temperature sensor 60 interrupts the cooling by cutting off the power of the air suction fan 30 and raises the temperature again. Repeat the process of performing the cooling process again.

On the other hand, the condensed water that may be generated inside the cooling coil pipe 10 by the minute temperature deviation is collected in the condensed water receiver 50 installed in the air delivery pipe 40 so that the injected air is completely contained so that a small amount of moisture is not included. Moisture removal is possible.

The degree of temperature deviation is reduced in proportion to the length of the cooling coil pipe 10, and is configured in an appropriate length in consideration of the size of the device and the allowable temperature deviation.

According to the present invention as described above, the temperature of the compressed air, which is formed higher than the outside air temperature in the air compressor, is cooled by coinciding with or close to the outside air while passing through a long cooling tube, thereby reducing the temperature difference between the object or the injection nozzle in contact with the injection air. It prevents the condensation caused by water and prevents water from being contained in the sprayed air. It is simple in structure, easy to maintain, and has the effect of improving practicality by reducing manufacturing costs.
