Description

The present invention is suitable for mounting or installing a gas-liquid separator that gas-liquid separates compressed air in an air tank supplied from, for example, an air compressor or the like, and performs gas-liquid separation of compressed air with high accuracy and efficiency. The present invention relates to a storage device for a gas-liquid separator that can safely supply separated, dried and dehumidified compressed air to an air tool and that allows the gas- liquid separator to be easily and safely installed at a desired position indoors and outdoors.

  The compressed air discharged from the air compressor contains water and oil, and if this compressed air is supplied to an air tool such as an air driver, impact wrench, or paint gun, the inside of the air conduit will rust, or the internal structure of the air tool Since parts may rust and malfunction and may cause malfunctions, a gas-liquid separator as an air dryer is attached to the compressed air discharge line to remove moisture, and dry compressed air is supplied to the air tool. I am doing so.

In the gas-liquid separator, for example, an upper cover communicating with the inside of the hollow cylindrical body is attached to an upper portion of the hollow cylindrical body, and a conduit for forming a compressed air conduit is formed in an inlet passage and an outlet passage provided on both sides of the cover. A plurality of partition structures, which are gas-liquid separation members, are screwed, a hollow cylindrical partition tube is disposed inside the hollow cylindrical body, and a convex portion, a recessed space, and a through-hole penetrating these are formed inside the partition tube. They are stacked.
Then, the compressed air introduced into the hollow cylindrical body from the inlet passage is guided to the lower side of the plurality of partition structures and ejected from the through-hole, and the water condensed by the adiabatic expansion is provided at the lower end of the hollow cylindrical body. The air that has been discharged from (not shown), removed moisture, and dried is discharged from the outlet passage and supplied to the air tool (see, for example, Patent Document 1).

However, since the gas-liquid separator is used by being inserted into a discharge pipe for compressed air, and the discharge pipe is usually arranged indoors in a factory or the like, the installation position and use location of the gas-liquid separator are There was a limited problem.
In addition, even if gas-liquid separation is performed by inserting a gas-liquid separator upstream or midstream of the discharge pipe, when water is supplied to the air tool, moisture is condensed and mixed again due to the ambient air temperature. Compressed air mixed with moisture due to a decrease in liquid separation condition is supplied to the air tool, causing the air tool to fail or functioning poorly, or making it impossible to perform the desired painting like a paint gun There was a problem of falling into impossibility.

  By the way, when the compressed air is efficiently and accurately separated by the gas-liquid separator, it is desired to supply the cooled and dried compressed air to the gas-liquid separator. Compressed air from the compressor is sent to a refrigeration air dryer. The refrigeration air dryer has a refrigeration circuit including a compressor, a condenser, and a cooler arranged in the air dryer body case, and the compressed air is supplied to the cooling chamber. Some have been fed, cooled and dried (see, for example, Patent Documents 2 and 3).

  However, the refrigeration air dryer is expensive to install, and when the air tool is used, the refrigeration air dryer is driven all the time.

  In order to solve the above problem, the first and second heat exchangers constituting the refrigeration circuit are arranged inside the air dryer, the refrigerant is supplied to these heat exchangers, and the refrigerant is introduced into the first heat exchanger. There is an air dryer in which the cooled water is cooled and introduced into the second heat exchanger, compressed air is introduced into the second heat exchanger, and the compressed air is cooled with the cooling water (for example, a patent) Reference 4).

  However, this air dryer requires cooling of the cooling water and requires the installation of a refrigeration circuit including the first and second heat exchangers for that purpose, resulting in problems such as increased equipment costs and operating costs. The

  As another means for cooling the compressed air with water, a compressed air pipe for introducing the compressed air of the air compressor is provided in the cooling water tank, a water-cooled aftercooler is provided at the bottom of the cooling water tank, and the compressed air is supplied to the aftercooler. There is one that is introduced and cooled, and the cooled compressed air is led to a refrigerating air dryer, and the compressed air is further cooled by the refrigerating pipe (see, for example, Patent Document 5).

  However, this device requires a refrigeration air dryer in addition to the water-cooled aftercooler, which increases the equipment costs and the operating costs, and also takes time to cool the compressed air. there were.

Further, the screw shafts of the legs 53 are screwed into the four corners of the bottom surface of the bottom plate 19, the back cover 20 is overlapped with the bent portions 16a, 17a, 18a, 19a, and this is screwed to fix the back of the storage box 6. Block.

Since the storage box 6 assembled in this way has a gas-liquid separator 29, a drain device 30 and the like disposed therein to protect them, for example, the storage box 6 can be installed outdoors away from the air tank 1. to become, it can be installed on the inside and outside of the factory in accordance with the gas-liquid separator 29 and the drain 30 or the like to use the environment of the air tool 49.

Next, when installing the cooling tank 4 and the storage box 6, it installs indoors or outdoors according to the installation position of the air tank 1, the use position of the air tool 49, and those installation environments.
For example, the cooling bath 4 is installed indoors or outdoors flat place away the air tank 1, set up a storage box 6 spaced from the cooling bath 4 in indoor or outdoor flat place, the storage box 6 The air tool 49 is disposed away from the air tool 49.
At that time, the cooling tank 4 in an empty state before introducing the cooling water is carried to an appropriate position while holding the handle 14 and installed on a predetermined installation surface 7. In addition, the storage box 6 holds the handle 23 and is carried to an appropriate position and installed on a predetermined installation surface 7.

In the embodiment, the storage box 6 is formed in a relatively compact size of 470 to 500 mm in length, 300 to 360 mm in width, and 300 to 360 mm in depth, and has a weight of 9 to 15 kg, so it can be easily carried by human power and installed. At that time, the height of the leg 53 is adjusted by rotating the leg 53, and the leg 53 is stably and horizontally installed on the installation surface 7.

In this case, since the cooling tank 4 is arranged by winding the cooling pipe 13 in a coil shape, the cooling pipe 13 is elongated and the cooling tank is compared with the case where the cooling pipe is bent and arranged in a zigzag shape. 4 can be downsized or the installation space can be made compact and the cooling capacity can be improved.
Therefore, the larger the cooling tank 4 is, the longer the cooling pipe 13 can be made and the cooling capacity can be improved. Therefore, the cooling tank 4 can be arranged close to the storage box 6 and the air tank 1. The installation space can be made compact.
Moreover, since the present invention does not require a cooling water cooling device, a refrigeration circuit, or a refrigeration air dryer in addition to the cooling tank 4, the equipment cost and the operation cost can be reduced accordingly.

Thus, after installing the cooling tank 4 and the storage box 6, the air tank 1 and the cooling tank 4 are connected via the air introduction pipe 2, the pressure regulating valve 3 is inserted into the conduit 2, and the cooling tank 4 and the storage box 6 are stored. The box 6 is connected via the air outlet pipe 5, the coupler 46 attached to the air outlet pipe 5 is connected to the coupler 44 on the inlet 42 side, and the coupler 45 attached to the outlet 43 is further connected to the coupler on the air supply pipe 47 side. 48, the other end of the air supply 47 is connected to the air tool 49, and the drain hose 52 is connected to the hose end 51.

Under such circumstances, the on-off valve 10 is opened, the on-off valve 11 is closed, and the cooling water 12 such as tap water is led from the water supply pipe 8 to the cooling tank 4 and stored, and is piped inside. The cooling pipe 13 is immersed in the cooling water 12, the introduction of the cooling water 12 is stopped, and the compressed air in the air tank 1 is introduced into the cooling tank 4 through the air introduction pipe 2.
The compressed air is first guided to the coiled portion 13 a of the cooling pipe 13, moves downward in a loop shape, and is cooled by the cooling water 12. At that time, the coil-shaped portion 13a is longer than a straight tube or a pipe obtained by bending it, and has a large contact area with the cooling water 12. Therefore, the compressed air is efficiently cooled, and at the same time, the saturated vapor pressure of the compressed air. Lowers and promotes dehumidification or drying.

Moreover, the centrifugal force acts on the compressed air in the coiled portion 13a, and the centrifugal force acting on the compressed air in the central portion of the pipe having a large flow velocity is larger than the centrifugal force acting on the compressed air having a small flow velocity near the inner wall of the tube. The compressed air at the center of the tube is pushed to the outside of the bent tube portion, and the compressed air near the inner wall of the tube goes around the inner wall of the bent tube portion along the inner wall.
Further, the pressure distribution on the inner wall surface of the coiled portion 13a is such that a pair of circulation flows that wrap around from the outside to the inside in a cross section perpendicular to the tube axis occurs because the outside of the curved pipe portion is high and the inside is low.
Therefore, the compressed air moving through the coiled portion 13a is urged to be stirred by the above-described action by the centrifugal force and the pair of circulation flows, and the cooling temperature becomes uniform and uniform.

Thus, the compressed air moving through the coiled portion 13a is gradually cooled as it moves downward from the upper portion, and is cooled by the cooling water 12 while moving up the straight pipe portion 13b from its lowest position, and the air is led out. The compressed air that has been sent out to the tube 5, uniformly cooled and dried is introduced into the storage box 6. This situation is shown in FIG.
