Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to an air tank for temporarily retaining pressurized air (compressed air) supplied to pneumatic equipment such as a pneumatic cylinder or an injection nozzle.

(Technical field) The air supplied from the compressed air supply source (air pump) through the main pipe contains moisture, so if it is sent directly to pneumatic equipment, it may cause malfunction or corrosion. It is made to collide with a spiral pipe or a baffle plate, and water droplets are attached to these to separate as much water as possible, and then it is supplied to each device through a distribution pipe such as cheese. In this way, in the past, it was necessary to supply pressurized air to multiple pneumatic devices through a water removal device and then through distribution piping, so if all the devices operated at the same time, There was an accident where the supply of pressurized air was temporarily insufficient, causing malfunction.

(Problems to be solved by the invention) In order to solve the above-mentioned problems, it may be possible to install an air tank between the distribution pipe and the moisture removal equipment, but this would be very expensive. Another drawback is that the installation area is large.

Therefore, the present invention attempts to solve the above-mentioned problems by equipping the air tank with moisture removal and distribution functions.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a partition wall 2 and a rectifying plate 3 in two stages, upper and lower, inside the tank body 1, so that the inside of the main body is an upper space. 4. It is divided into an intermediate space 5 and a lower space 6, of which the upper space 4 and the lower space 6 are communicated by a flow pipe 7 provided through the partition wall 3 and the rectifying plate 3. However, the upper space 4 and the middle space 5 are separated by the partition wall 2, and the middle space 5 and the lower space 6 are communicated with each other with a rectifying plate 3 in between. A rectifying vane 3a is provided to form a spiral flow in the pressurized air flowing into the lower space 6 from the space 5, and a metal cylindrical filter 8 directly connected to the flow pipe 7 is provided in the lower space 6. , an air inlet 9 is connected to the tank body side wall 1a communicating with the intermediate cavity 5, a drain outlet 10 is connected to the tank body bottom wall 1b communicating with the lower cavity 6, and further communicates with the upper cavity 4. A configuration is adopted in which a plurality of air outlet ports 11 are respectively provided on the upper wall 1c of the tank body.

(Function) From the air inlet 9 to the intermediate space 5 of the tank body 1
The pressure air flowing into each rectifying blade 3 of the rectifying plate 3
a, it is sent into the lower cavity 6 in a spiral shape, and then passes through a metal cylindrical filter 8 provided in the lower cavity, and flows through the flow pipe 7 to the upper cavity 4. The air is sent to each pneumatic device through a plurality of air outlet ports 11 communicating therewith and each branch pipe connected thereto, but in this case, for example, 30 pieces of pressurized air are constantly retained in the tank body 1. At the same time, when passing through the tank body 1, the pressurized air collides with the partition wall 2, the rectifier plate 3, and the metal cylindrical filter 8, causing water droplets to adhere to these, which accumulate on the tank body bottom wall 1b, The pressurized air is discharged from the drain outlet 10 as required, and the pressurized air is filtered by a metal cylindrical filter 8 to remove foreign substances such as dust.

Therefore, a certain amount of pressurized air is always retained in this tank body 1, so even if multiple pneumatic devices connected to this are activated all at once, the pressurized air in the tank body is immediately supplied. , there will be no malfunction due to insufficient supply. At the same time, moisture in the pressurized air is separated and filtered within the tank body 1, so that the pneumatic equipment will not be damaged.

(Example) In Fig. 1, 1 is a pressure-resistant tank body capable of permanently retaining pressurized air having a pressure of, for example, 7 kgf/cm ² G, and 12 is a tank main body that is capable of retaining pressure air having a pressure of 7 Kgf/cm 2 G, and 12 is a tank body that is capable of retaining pressure air having a pressure of 7 Kgf/cm 2 G. A main pipe for sending air into the tank body 1, a branch pipe 13 for supplying pressurized air from the tank body 1 to each pneumatic device, and a branch pipe 14 for discharging water (drain) accumulated in the tank body 1. 15 is a pressure gauge having an on-off valve, and 16 is a safety valve.

In Figure 2, there are two upper and lower parts inside the tank body 1.
The partition wall 2 and the rectifying plate 3 are fixed to each other in stages, so that the inside of the main body is divided into an upper space 4, an intermediate space 5,
and a lower space 6. The upper cavity 4 and the lower cavity 6 are communicated by a flow pipe 7 provided through the partition wall 2 and the rectifying plate 3, but the upper cavity 4 and the intermediate cavity 5 are connected to the partition wall 2 is blocked by. A cylindrical filter 8 made of metal such as stainless steel is fixed to the lower space 6 and is directly connected to the flow pipe 7 . As shown in FIG. 3, the rectifying plate 3 concentrically connected to the partition wall 2 has rectifying vanes 3a, 3a, . As shown in FIG. 4, the cylindrical filter 8 is a mesh-like filter member 8a made of two or three layers of metal fibers woven into a net or cloth.
is sandwiched between metal perforated plates (punch plates) 8b, and when pressurized air passes through this mesh-like filter member 8a, water droplets adhere to it and are not filtered. That will happen. Note that this filter 8 is also provided on the upper end surface of the flow pipe 7 passing through the partition wall 2, as shown in FIG. Note that in FIG. 2, and especially in FIG. 3, a metal disc 17 with a slightly downward slope is fixed to the outer periphery of the lower end of the cylindrical filter 8, but this is to guide water droplets to the bottom wall 1b of the tank body. , the pressurized air collides with the disk so that water droplets tend to adhere thereto as well. An air inlet 9 is provided in the side wall 1a of the tank body in communication with the intermediate space 5 of the tank body 1, and a drain outlet 10 is provided in the bottom wall 1b of the tank body. Further, a plurality of air outlets 11, for example, 6 to 7 air outlets 11, are provided in the upper wall 1c of the tank body 1 in communication with the upper cavity 4, and each of these air outlets 11 is connected to the air outlet 11 required for each pneumatic equipment. It is preferable to form the pipes with different diameters depending on the unit supply amount, and although this is possible according to the present invention, this was not possible with conventional distribution pipes. A main pipe 12, a drain pipe 14, and a branch pipe 13 are connected to the air inlet 9, drain outlet 10, and air outlet 11 by, for example, a union joint 18. 19 is a supporting leg.

(Effects) According to the present invention, since the water removal section, the filtration section, and the distribution section are provided in the tank body,
No need for piping to connect each,
The structure is simple and can be manufactured at low cost, the installation area is very small, and there are advantages that even if a large number of pneumatic devices operate at the same time, malfunctions due to insufficient air pressure will not occur.
