Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention replaces stored itemsMethodandOil / water separatorIn more detail, this is a tank that contains the storage items that need to be replaced because the fluid flows inside and the function deteriorates after a certain period of time.BodyReplace only the stored itemsMethodandOil / water separatorIt is about.
[0002]
[Prior art]
In the conventional case, the fluid flows through the inside, and the function deteriorates when a certain period of time is used, so it corresponds to the stored item that needs to be replaced. The most common is the filter element, which contains storage items with reduced functionality.
[0003]
[Problems to be solved by the invention]
  However, such conventional, stored item replacementMethodandOil / water separatorThere were problems as shown below.
[0004]
First of all, when trying to replace the filter element containing the original storage items that need to be replaced because the function deteriorates after a certain period of time, the filter element itself is considered for convenience of transportation, inventory and replacement. First, the filter element was exchanged in a state in which the case main body is present and the original storage product that needs to be replaced is accommodated because the function deteriorates when a certain period is used. Naturally, the case main body has been discarded in accordance with the exchange of the stored items, although it is not related to the deterioration of the function.
[0005]
If an unspecified number of people try to replace only the original stored items that need to be replaced after a certain period of time, the function will deteriorate. It was difficult to ensure the later performance reliably.
[0006]
On the other hand, in order for a person with a certain technology to exchange only the storage items that need to be replaced because the function deteriorates after a certain period of time, a person with a certain technology goes directly or exchanges It is necessary to send a tank in which a stored item that needs to be stored to a predetermined place. In this case, there is a problem in terms of work efficiency, such as requiring many people for the time of reciprocating movement for people to go out, and in order to send the tank to a predetermined place, it stays inside. When the drain water leaked, it became dirty and had a hard time making packing to send it in a stable state.
The present invention aims to solve such problems.

FIG. 6 is a sectional view of an adsorption tank, and FIG. 6 is a tank used in the present invention.BodyIt is the figure which showed the condition at the time of carrying.
[0010]
(First embodiment)
As shown in FIG. 1, reference numeral 10 denotes an air compressor, which is composed of a motor 11, a compressor 12, and an air tank 13. By transmitting the rotation of the motor 11 to the compressor 12 by a belt 14, Stores compressed air.
[0011]
Here, the compressed air stored in the air tank 13 passes through the compressed air pipe 111, the aftercooler 20, the compressed air pipe 112, the dryer 30, the compressed air pipe 113, the air filter 40, and the compressed air pipe 114. Compressed air can be supplied via.
[0012]
In this case, the compressed air is dried by the aftercooler 20 and the dryer 30 and the foreign matter is removed by the air filter 40 so that the dried beautiful compressed air can be fed.
[0013]
On the other hand, from the lower part of the air tank 13, a drain pipe 121, an openable / closable valve 122, a drain pipe 123, an electric drain trap 124 that discharges drain water together with compressed air by some signal, and a drain pipe 125. It is connected to the drain collecting pipe 161 via, and drain water can be discharged.
[0014]
Further, the aftercooler 20 includes a drain pipe 131, a valve 132 that can be opened and closed, a drain pipe 133, an electric drain trap 134 that discharges drain water together with compressed air by some signal, and a drain pipe 135. Via, it is connected to a drain collecting pipe 161, and drain water can be discharged.
[0015]
Furthermore, from the dryer 30, the drain pipe 141, the openable / closable valve 142, the drain pipe 143, the electric drain trap 144 that discharges drain water together with the compressed air by any signal, and the drain pipe 145 are passed through. Then, it is connected to the drain collecting pipe 161 so that drain water can be discharged.
[0016]
In addition, from the air filter 40, a drain pipe 151, a valve 152 that can be opened and closed, a drain pipe 153, an electric drain trap 154 that discharges drain water together with compressed air by any signal, and a drain pipe 155. It is connected to the drain collecting pipe 161 via, and drain water can be discharged.
[0017]
Here, from the drain collecting pipe 161, fresh water is discharged from the fresh water pipe 173 via the check valve 162, the drain collecting pipe 163, and the oil / water separator 210 for separating oil and various foreign substances. Yes. In this case, the check valve 162 allows drain water to pass from the drain collecting pipe 161 to the drain collecting pipe 163, but does not cause the drain water to flow backward from the drain collecting pipe 163 to the drain collecting pipe 161.
[0018]
The oil / water separation device 210 includes an oil / water separation tank 50 and two oil decomposition / adsorption tanks 60, and the oil / water separation tank 50 and the oil decomposition / adsorption tank 60 are connected by a fresh water pipe 171. 60 is connected by a fresh water pipe 172. However, the oil decomposition adsorption tank 60 does not need to be limited to two, and may be one, three, or more.
[0019]
In this case, the oil / water separation tank 50 communicates with the inside of the sealed oil / water separation tank main body 50a in a state in which compressed air, which is a gas, can enter and exit in the upper part and a state in which drain water, which is a liquid, can enter and exit in the lower part. It is partitioned by a partition plate 50d to form two chambers, an oil floating separation chamber 50b and a water storage chamber 50c.
[0020]
And the other end of the inlet pipe 50e connected to the drain collecting pipe 163 via the joint 50h is located in the upper part of the oil floating separation chamber 50b, and drain water flows into it. Accordingly, in the oil floating separation chamber 50b, oil lighter than water floats on the liquid surface, and foreign matters heavier than water settle on the bottom.
[0021]
On the other hand, in the water storage chamber 50c, the pipe end 50g, which is the end of the outlet pipe 50f, is positioned on the liquid surface, and is lighter than water than the lower communicating portion between the oil floating separation chamber 50b and the water storage chamber 50c. Drain water from which foreign substances heavier than oil and water have been removed flows. Here, the outlet pipe 50f is connected to the fresh water pipe 171 through the joint 50i. Therefore, clean drain water from which the oil collected on the liquid surface of the water storage chamber 50c is removed is fed into the outlet pipe 50f.
[0022]
  The oil decomposition adsorption tank 60 is a tank in which the stored items 341, 342, and 343 are stored.Body61 and the tankBodyA base 321 for fixing 61 to the ground, and a tankBodyIt is composed of four nuts 305 for fixing 61 to the mount 321.
[0023]
  Also tankBodyReference numeral 61 denotes a cylinder 301, two upper and lower lids 302, two upper and lower O-rings 303 that prevent leakage of fluid inside the simple 301, and two upper and lower lids 302 that sandwich the O-ring 303 and the cylinder 301. Are connected to four bolts 304 that pass through the pipe 304, eight nuts 305 that fix the cylinder 301, the upper and lower O-rings 303 and the lid 302 at both ends of the bolt 304, and fresh water pipes 171, 172, and 173. It consists of two upper and lower hose joints 310.
[0024]
Further, the hose joint 310 is composed of a joint body 311, a nut 312, and a sleeve 313, and the male thread portion of the joint body 311 is connected to the central portion of the lid 302 by screwing. In addition, the hose coupling 310 has a sleeve 313 inserted into the fresh water pipes 171, 172, and 173, and the coupling body 311 and the nut 312 are coupled by screwing in a state where the sleeve 313 is sandwiched between the coupling body 311 and the nut 312. The fresh water pipes 171, 172, and 173 are firmly connected to the hose joint 310. The fresh water pipes 171, 172, 173 may be steel pipes or vinyl pipes.
[0025]
In addition, in the cylinder 301, there are stored exchangeable storage items 341, 342, and 343 that need to be replaced because the function is deteriorated when a period in which the fluid flows inside is used. The stored items 341, 342, and 343 include an oil adsorbent 342 that adsorbs oil, an amine adsorbent 341 in which an amine that destroys emulsion oil and coarsens oil adheres to the oil adsorbent 342, For example, activated carbon 343 that adsorbs a bad odor.
[0026]
In this case, space portions are secured on the inlet side and the outlet side of the cylinder 301 so that the drain water which is liquid flows uniformly in the cylinder 301. Therefore, in order to secure a space, the punching plate 331 is supported by the gap tube 332 on the lid 302, and the stored items 341, 342, and 343 are stored between the two punching plates 331.
[0027]
Here, the oil adsorbent 341 and the oil adsorbent 342, which are exchangeable storage items 341 and 342, increase in resistance as they absorb foreign substances such as oil, and are pushed toward one side while being compressed. Therefore, in order to prevent this even a little, the intermediate porous plate 333 is disposed in the substantially central portion of the cylinder 301 so as to vertically block the liquid flow, and the intermediate porous plate 333 is supported to support the intermediate porous plate 333. A holding cylinder 334 is disposed between the punching plate 331 and the compression preventing means 333 and 334.
[0028]
As shown in FIG. 2, activated carbon 343 is disposed immediately downstream of the intermediate perforated plate 333 and the amine-adsorbed oil adsorbent 341 and the oil adsorbed as a method of accommodating the stored items 341, 342, and 343 inside the cylinder 301. The material 342 may be mixed uniformly and stored in the remaining portion. In this case, the activated carbon 343 may be disposed immediately upstream of the intermediate porous plate 333 or may be disposed immediately before or immediately before the punching plate 331 at the inlet or outlet.
Further, all the stored items 341, 342, and 343 may be mixed and stored uniformly.
[0029]
On the other hand, without mixing the amine-adsorbed oil adsorbent 341 and the oil adsorbent 342, one or two lumps are mixed, and the oil adsorbent 342, the amine-adsorbed oil adsorbent 341 and the oil are formed from the inlet to the outlet of the cylinder 301. Arranged in the order of the adsorbent 342, or arranged in the order of the amine adsorbent 341 and the oil adsorbent 342, either the end of the amine adsorbent 341 and the oil adsorbent 342 or any part of the boundary portion It is also conceivable to arrange activated carbon 343 on the surface.
[0030]
Further, the amine remains in the form of particles as one lump, and the oil adsorbent 342 as one or two lumps, and the oil adsorbent 342, the amine and the oil adsorbent 342 are moved from the inlet to the outlet of the cylinder 301. It is also conceivable to arrange the activated carbon 343 at any part of the end portion or the boundary portion of the amine and the oil adsorbent 342 by arranging them in order or in the order of the amine and the oil adsorbent 342.
[0031]
However, in any of the cases described above, a configuration in which the activated carbon 343 is not disposed is also conceivable.
[0032]
  Replacement of stored items according to the present inventionMethodandOil / water separatorIs configured as described above, and its operation will be described below.
[0033]
First, when the motor 11 constituting the air compressor 10 is operated, the rotation of the motor 11 is transmitted to the compressor 12 via the belt 14 and the compressed air is stored in the air tank 13. Here, the compressed air stored in the air tank 13 passes through the compressed air pipe 111, the aftercooler 20, the compressed air pipe 112, the dryer 30, the compressed air pipe 113, the air filter 40, and the compressed air pipe 114. It is possible to send dry and clean compressed air to the actuators of this as needed.
[0034]
On the other hand, the drain water generated from the compressed air by the air tank 13, the aftercooler 20, the dryer 30 and the air filter 40 together with the compressed air, the drain pipes 121, 131, 141, 151 and the valves 122, 132, 142, 152 and the drain pipe 123. 133, 143, and 153, drain traps 124, 134, 144, and 154 and drain pipes 125, 135, 145, and 155, merge at drain collecting pipe 161, and check valve 162 and drain collecting pipe 163 The oil / water separator 210 is configured to remove various foreign substances including oil and to discharge fresh water from the fresh water pipe 173.
[0035]
In this case, in the oil / water separator 210, first, in the oil floating separation chamber 50b of the oil / water separation tank 50, oil lighter than water is floated on the water surface, and various foreign matters heavier than water are precipitated at the bottom, and the oil floating separation chamber 50b Clean drain water from which oil and various foreign substances have been removed is fed into the water storage chamber 50c through the lower communicating portion between the water storage chambers 50c. On the other hand, the compressed air sent together with the drain water stays in the upper part of the oil / water separation tank 50.
[0036]
Here, when the drain water sent into the water storage chamber 50c accumulates above the pipe end 50g, which is the end of the outlet pipe 50f disposed in the water storage chamber 50c, the drain water stays in the upper part of the oil / water separation tank 50. The compressed air is fed into the oil decomposition adsorption tank 60 through the outlet pipe 50f and the fresh water pipe 171. In this case, the force of the compressed air assists the movement of the drain water until the drain water is discharged from the fresh water pipe 173 because the oil decomposition adsorption tank 60 is in a sealed state.
[0037]
However, although oil and various foreign substances are separated in the oil floating separation chamber 50b of the oil / water separation tank 50, the emulsified oil is fed into the oil decomposition adsorption tank 60 in a state of being dissolved in the drain water.
[0038]
Therefore, in the oil decomposition adsorption tank 60, when the emulsified oil comes into contact with the amine, the oil is separated from the water, and the separated oil becomes coarse. Then, the cleanliness of the drain water is improved by the coarsened oil being adsorbed by the oil adsorbent 342. Further, when the drain water passes through the activated carbon 343, the odor is removed.
[0039]
In this way, depending on how dirty the drain water is, it is possible to connect one or more three or more oil decomposition adsorption tanks 60.
[0040]
  On the other hand, the tank which comprises the oil decomposition adsorption tank 60BodyWhen the functions of the stored items 341, 342, and 343 stored in 61 are deteriorated, the stored items 341, 342, and 343 need to be replaced.
[0041]
  In this case, it is ideal to replace only the necessary items from the meaning of eliminating waste, that is, only the stored items 341, 342, and 343 having reduced functions. The replacement is preferably performed by a technically skilled person in order to ensure performance. Therefore, in consideration of the efficiency at the time of replacement, the tanks in which the storage items 341, 342, 343 having reduced functions are storedBody61 is sent to a predetermined place, and only the stored items 341, 342, 343 having reduced functions are replaced with those having a predetermined function, and the replaced tankBody61 is sent back to the original place, and again in the oil decomposition adsorption tank 60powered byAnd making a system that uses it.
[0042]
  In addition, the tankBodyAt the time of carrying 61, means 171, 172, 173, 302, and 390 for carrying the convenience of carrying are provided. In this case, as a means for transporting 171, 172, 173, 390, the tankBodyLeakage prevention means 171, 172, 173, and 390 are provided so that drain water does not leak when transporting 61. In addition, the leakage prevention means 171, 172, 173, 390 is provided with a blind plug 390 instead of the hose joint 310, or with vinyl fresh water pipes 171, 172, 173 connected to the hose joint 310. One end remaining after cutting is heated to be in a sealed state.
[0043]
  On the other hand, as another means 302 for carrying, a tank composed of a cylinder 301, upper and lower lids 302 and other parts.Body61, the upper and lower lids 302 have a square shape so that they can be housed in a stable state during transport. However, the upper and lower lids 302 may be triangular. Of course, in this case, the number of bolts 304 and nuts 305 for fixing the upper and lower lids 302 and the cylinder 301 changes.
[0044]
  In addition, in order to clarify the point of processing for exchanging only the storage items 341, 342, and 343 having such reduced functions,Body61 in any part of the tankBodyA sticker 380 that includes any one of 61 exchange methods, delivery methods, and spare parts is attached.
[0045]
(Second embodiment)
The difference between the second embodiment and the first embodiment is that the oil / water separation device 220 is composed of an oil / water separation tank 50, an oil decomposition tank 70, and an oil adsorption tank 80, as shown in FIG. It is connecting and discharging at 181, 182, and 183. That is, instead of the two oil decomposition adsorption tanks 60, the oil decomposition tank 70 for decomposing the emulsified oil and the oil adsorption tank 80 for adsorbing the coarse oil are separately provided. Note that the materials of the fresh water pipes 181, 182, and 183 may be considered the same as the fresh water pipes 171, 172, and 173 of the first embodiment.
[0046]
In this case, in the oil decomposition tank 70, as a method of storing the stored items 341 and 343 inside the cylinder 301, as shown in FIG. 4, only the activated carbon 343 is disposed immediately downstream of the intermediate porous plate 333 and the oil with amine is added. The adsorbent 341 may be stored in the remaining part. In this case, the activated carbon 343 may be disposed immediately upstream of the intermediate porous plate 333 or may be disposed immediately before or immediately before the punching plate 331 at the inlet or outlet. Further, all the stored items 341 and 343 may be mixed and stored uniformly.
[0047]
On the other hand, the oil adsorbent 342 and the amine are formed from the inlet to the outlet of the cylinder 301 by making the amine adsorbed as particles into one lump, and the oil adsorbent 342 before adhering the amine as one or two lumps. The activated carbon 343 may be disposed at any end portion or boundary portion of the amine and the oil adsorbent 342 by arranging them in the order of the oil adsorbent 342 or in the order of the amine and the oil adsorbent 342. Conceivable.
[0048]
Moreover, in the oil adsorption tank 80, as a method for accommodating the articles 342 and 343 inside the cylinder 301, as shown in FIG. 5, only the activated carbon 343 is disposed immediately downstream of the intermediate porous plate 333, and the oil adsorbent 342 is disposed. May be stored in the remaining portion. In this case, the activated carbon 343 may be disposed immediately upstream of the intermediate porous plate 333 or may be disposed immediately before or immediately before the punching plate 331 at the inlet or outlet. Further, all the stored items 341 and 343 may be mixed and stored uniformly.
[0049]
However, in any case of the oil decomposition tank 70 and the oil adsorption tank 80, a configuration in which the activated carbon 343 is not disposed is conceivable.
[0050]
The concept of the means for transporting 181, 182, 183, 302, and 390 and the leakage prevention means 181, 182, 183, and 390 are the same as those in the first embodiment, and detailed description thereof is omitted. Further, the compression preventing means 333 and 334 are the same as those in the first embodiment. Furthermore, a plurality of oil decomposition tanks 70 and oil adsorption tanks 80 can be installed.
[0051]
  Finally, since the operation is substantially the same as that of the first embodiment, a description thereof will be omitted. However, the main difference is that the oil decomposition tank 70 and the oil adsorption tank 80 have different functions from the oil decomposition adsorption tank 60, but the function deteriorates if a period in which the fluid flows inside the oil decomposition tank 70 and needs to be replaced. There are tanks for storing exchangeable items 341, 342, 343BodyWhen there are 71 and 81 and the functions of the storage items 341, 342, and 343 deteriorate, only the storage products 341, 342, and 343 whose functions have been reduced are replaced with those having a predetermined function and used again. Is the same as in the first embodiment.
[0052]
【The invention's effect】
As is clear from the above description, the present invention can provide the following effects.
[0053]
  First, stored goods replacement according to the present inventionMethodBy using a period when fluid flows through the tank, the tank will contain items that need to be replaced because the function will deteriorate.BodyIt is now possible to replace only the stored items with reduced functions with those having a predetermined function.
[0054]
Secondly, by replacing only the stored items with reduced functions with those having a predetermined function, it is possible to eliminate the waste of exchanging even the ones with the conventional functions not deteriorated.
[0055]
  Third, the tank that holds the storage items that need to be replaced due to the reduced functionBodyBy sending the tank to a predetermined place, a skilled person can perform the replacement procedure, and it is possible to reduce quality and eliminate waste.
[0056]
  Fourthly, by arranging means for transportation pursuing the convenience of transportation, the tankBodyHowever, it was possible to carry it relatively easily even though it contained dirty drain water and was quite heavy.
