The support member 22 of the air dryer 2 is provided with an inlet (not shown) for introducing the compressed air compressed by the compressor 1 and an outlet (not shown) for discharging the dry compressed air. .
  The oil separator 3 includes a case 31 as a bottomed cylindrical casing extending in the vertical direction, and a lid 32 that closes the opening of the case 31. The bottom 31a of the case 31 is provided with a drain discharge port 33 for discharging the accumulated drain. A drain hose 34 used when taking out the drain is connected to the drain outlet 33. The lid 32 is separately formed with an inlet 35 for introducing purge air from the air dryer 2 via the connection hose 25 and an outlet 40 for discharging clean air from which oil has been separated. The introduction port 35 and the connection hose 25 are connected by a connecting member 27.
An attachment member 37 is integrally provided on the lid 32 of the oil separator 3 with respect to the lid 32. The attachment member 37 is fixed to the chassis 38 by bolts 39.
Moreover, the front-end | tip part of the drain hose 34 is attached to the supporting member 90 fixed to the chassis 38 etc. of the vehicle so that attachment or detachment is possible. That is, the fixing member 91 is fixed to the support member 90. A one-touch coupler 92 for fixing the tip end portion of the drain hose 34 with one touch is fixed to the lower end portion of the fixing member 91. The leading end of the drain hose 34 is fixed to the fixing member 91 by being inserted into the one-touch coupler 92, and can be detached from the fixing member 91 by operating the one-touch coupler 92. The distal end portion of the drain hose 34 is attached to the fixing member 91 upward in the vertical direction.
  An elbow member 60 bent from the horizontal direction vertically upward is screwed into the discharge port 40 of the oil separator 3. A liquid dripping prevention member 70 is attached to the tip of the elbow member 60, and a cover 80 for preventing intrusion of dust and the like is attached.
  As shown in FIG. 3, the inlet 32 and the outlet 40 are opened in the same direction (right side in the figure) in the lid 32. The introduction port 35 and the discharge port 40 are respectively provided on surfaces in the horizontal direction. The connection hose 25 is connected to the introduction port 35 via a connecting member 27. An elbow member 60 is connected to the discharge port 40. That is, the connecting member 27 and the elbow member 60 are provided side by side.
  As shown in FIG. 4, the lid 32 has a bottomed cylindrical shape with the top vertically closed. Two baffle plates 46 are erected on the inner wall of the lid 32 in the vicinity of the inlet 35 so as to be orthogonal to the traveling direction of the purge air introduced from the inlet 35. The internal space of the lid 32 functions as a first expansion chamber 45 that expands purge air introduced from the introduction port 35. The lid 32 is formed with a communication portion 32 a that communicates from the inside of the case 31 to the discharge port 40.
  As shown in FIGS. 5 and 6, a disc-shaped cover 47 that closes the case 31 and closes the lid 32 is provided between the case 31 and the lid 32. The cover 47 is fastened to the lid 32 together with the case 31 by bolts 36. That is, the bolt 36 is fastened to the screw hole 32 c formed in the flange portion 32 b provided in the lid 32. The bolt 36 and the screw hole 32c function as an attaching / detaching mechanism. Further, the screw portion of the bolt 36 is passed through a through hole formed in the flange portion 31 b provided in the case 31. The cover 47 is formed with a through hole through which the threaded portion of the bolt 36 passes. Therefore, the screw portion of the bolt 36 is passed through the through hole of the flange portion 31 b of the case 31 and the through hole of the flange portion 47 a of the cover 47, and the bolt 36 is screwed into the screw hole 32 c of the flange portion 32 b of the lid 32. Thus, the lid 32, the cover 47, and the case 31 are fastened. The case 31 can be removed from the lid 32 by removing the bolt 36 from the screw hole 32c. The cover 47 is formed with a communication hole 47 c that communicates from the inside of the case 31 to the discharge port 40.
  The space formed by the lid 32 and the cover 47 functions as the first expansion chamber 45. The cover 47 is fixed with a bolt 36 with a bottomed cylindrical housing member 48 closed in the vertical direction for housing the urethane foam 50 such as sponge. The urethane foam 50 functions as a collision material. A flange portion 48 a and a flange portion 48 b are formed on the upper end edge portion and the lower end edge portion of the housing member 48. The bolt 36 is passed through a flange portion 48 a formed at the upper edge of the housing member 48, and the housing member 48 is fastened to the cover 47. A space formed by the cover 47 and the upper surface of the housing member 48 functions as the second expansion chamber 51. The cover 47 is formed with a plurality of through holes 47 b that allow the first expansion chamber 45 and the second expansion chamber 51 to communicate with each other. A plurality of through holes 49 a are formed in the central portion of the upper bottom portion 49 of the housing member 48. The through hole 47 b of the cover 47 and the through hole 49 a of the upper bottom portion 49 of the housing member 48 are formed at positions that do not face each other. A plurality of through holes 48 c are formed on the lower end side of the side surface of the housing member 48 at intervals in the radial direction.
  A disc-shaped support lid 52 that supports the accommodated urethane foam 50 is fixed to the flange portion 48 b formed at the lower end edge of the accommodation member 48 by screws 53. The support lid 52 is formed to have substantially the same diameter as the inner diameter of the case 31. A space formed by the upper bottom 49 of the housing member 48 and the support lid 52 functions as the third expansion chamber 59. The support lid 52 is formed with a plurality of through holes 52a through which oil and water removed by the urethane foam 50 is dropped. Therefore, the lower part in the case 31 functions as the drain reservoir 54.
  The drain reservoir 54 is provided with a heater 55 as a heating means for heating the accumulated drain and evaporating water. The heater 55 is inserted into the case 31 through an insertion hole 56 formed on the side surface of the case 31. The heater 55 directly heats the drain accumulated in the drain reservoir 54. The heater 55 controls heating by a thermostat (not shown).
  As shown in FIGS. 7 and 8, the elbow member 60 includes a horizontal portion 61 extending in the horizontal direction and a vertical portion 62 extending in the vertical direction continuously to the horizontal portion 61. A male screw portion 63 that is screwed into the female screw portion 40 a of the discharge port 40 is formed at the base end portion of the elbow member 60. The male screw part 63 of the elbow member 60 is formed such that when the elbow member 60 is screwed to the female screw part 40a of the discharge port 40, fastening is stopped at a position where the tip of the elbow member 60 faces upward. A female screw portion 64 to which the dripping prevention member 70 is screwed is formed at the tip of the elbow member 60. When the drain flows into the elbow member 60, the vertical portion 62 prevents the drain from flowing out.
  Inside the liquid dripping prevention member 70, a through hole 71 that connects the base end and the tip end is formed, and four partition plates 72 that prevent the entry of large foreign substances that block the flow path are provided. The partition plates 72 are formed to extend in the axial direction at equal intervals in the circumferential direction. A cylindrical portion 73 is formed at the center of the through hole 71 and at the portion where the partition plate 72 intersects. A male screw portion 74 that is screwed to the female screw portion 64 of the elbow member 60 is formed at the base end portion of the liquid dripping prevention member 70. On the side surface of the opening 75 at the tip of the liquid dripping prevention member 70, a liquid dripping part 76 that receives the liquid dripping from the opening 75 is formed over the entire circumference. A return hole 77 as a return part for returning the liquid received by the liquid drooping portion 76 to the through hole 71 is formed at the bottom of the liquid drooping portion 76. The return hole 77 penetrates from the liquid drooping portion 76 to the through hole 71. Accordingly, the liquid dripping on the liquid drooping portion 76 returns to the elbow member 60 through the return hole 77.
  A columnar insertion portion 81 that protrudes into the cylindrical portion 73 of the liquid dripping prevention member 70 projects from the inside of the cover 80. A step portion 82 is formed in the insertion portion 81, and the insertion position of the cover 80 with respect to the dripping prevention member 70 is set. The cover 80 covers the opening 75 of the liquid dripping prevention member 70. The outer diameter of the cover 80 is formed smaller than the inner diameter of the liquid drooping portion 76. Therefore, the clean air that has passed through the dripping prevention member 70 passes between the opening 75 of the dripping prevention member 70 and the inner surface of the cover 80 and is discharged to the outside.
Next, the operation of the oil separator 3 configured as described above will be described.
As shown in FIG. 2, purge air discharged from the air dryer 2 is introduced into the oil separator 3. The purge air is air containing oil and water.
As shown in FIG. 4, the purge air introduced from the introduction port 35 collides with the baffle plate 46, is introduced into the oil separator 3 along the baffle plate 46, and expands in the first expansion chamber 45.
As shown in FIG. 5, the air expanded in the first expansion chamber 45 enters the second expansion chamber 51 through a through hole 47 b formed in the cover 47. The air expanded in the second expansion chamber 51 enters the third expansion chamber 59 from the through hole 49a in the upper bottom portion 49 of the housing member 48, and the oil and water colliding with the urethane foam 50 are separated from the air. The drain containing moisture and oil captured by the urethane foam 50 reaches the upper surface of the support lid 52 through the urethane foam 50, falls from the through hole 52a of the support lid 52 to the drain reservoir 54, and is stored in the drain reservoir. It collects in the part 54. The drain accumulated in the drain reservoir 54 enters the drain hose 34 from the drain discharge port 33. The drain accumulated in the drain reservoir 54 is heated by the heater 55 and the water in the drain is evaporated.
  By the way, when the front end portion of the drain hose 34 is removed from the fixing member 91, the atmosphere flows into the fixing member 91, and the drain in the drain hose 34 is positioned at the same height as the drain in the drain reservoir 54. Therefore, if the drain in the drain hose 34 can be seen, the amount of drain in the drain reservoir 54 can be confirmed.
  On the other hand, as shown in FIG. 6, air that has entered the third expansion chamber 59 from the through hole 49 a in the upper bottom portion 49 of the housing member 48 and separated the oil and water is passed through the through hole 48 c on the side surface of the housing member 48. Enters the case 31. The air that has entered the case 31 passes through the communication hole 47c of the cover 47 and the communication portion 32a of the lid 32, flows into the elbow member 60 from the discharge port 40, and is discharged to the atmosphere. Therefore, the air that has entered the case 31 is discharged from the discharge port 40 with almost no contact with the drain of the drain reservoir 54. The air discharged from the discharge port 40 is clean air that does not contain oil.
  When discharging the drain accumulated in the drain reservoir 54, the one-touch coupler 92 is operated to remove the tip of the drain hose 34 from the one-touch coupler 92, and the tip of the drain hose 34 is drained from the drain reservoir 54. It can be discharged by making it lower than the surface of the water.
  When cleaning the inside of the case 31 or replacing the urethane foam 50 as a collision material, the case 31 and the cover 47 are removed from the lid 32 by removing the bolt 36 from the screw hole 32c. Then, the removed case 31 and the cover 47 can be washed. Further, the screw 53 fixing the support lid 52 to the housing member 48 is removed, the urethane foam 50 is taken out from the housing member 48, and the urethane foam 50 is replaced. After the replacement, the case 31 and the cover 47 are attached to the lid 32 by fixing the support lid 52 to the housing member 48 with the screw 53 and fastening the bolt 36 to the screw hole 32 c of the lid 32.
As described above, according to the embodiment described above, the following effects can be obtained.
(1) The introduction port 35 and the discharge port 40 are provided in the lid 32, and purge air introduced into the case 31 from the introduction port 35 passes vertically through the plurality of expansion chambers 45, 51, 59 and the discharge port 40. Clean air is discharged from the case 31, and the case 31 can be removed from or attached to the lid 32 by the bolt 36 and the screw hole 32c as an attaching / detaching mechanism. For this reason, the case can be easily separated by removing the case 31 from the lid 32.
  (2) The introduction port 35 and the discharge port 40 are provided on the horizontal surface of the lid 32, respectively. For this reason, since the case 31 does not have the introduction port 35 and the discharge port 40, when removing the case 31 from the lid 32, there is no pipe connected to the case 31 and the removal is easy. Moreover, since the pipe is not connected to the upper surface or the bottom surface in the vertical direction of the lid 32, the length in the vertical direction can be suppressed.
  (3) The heater 55 is inserted from the insertion hole 56 provided in the lower part of the case 31, and the heater 55 directly heats the drain. For this reason, the water | moisture content contained in a drain is evaporated, the quantity of drain can be reduced, the frequency | count of removing the case 31 from the lid | cover 32 can be suppressed, and the lifetime of an attachment or detachment mechanism can be lengthened. Further, heat transfer from the heater 55 to the drain is high, and the drain can be heated more efficiently than indirectly heating the drain.
In addition, the said embodiment can be implemented with the following forms which changed this suitably.
-In above-mentioned embodiment, although the volt | bolt 36 was fastened to the screw hole 32c as an attachment / detachment mechanism, you may employ | adopt another attachment / detachment mechanism. For example, as shown in FIG. 9, a clamp ring 100 that sandwiches the flange portion 32b of the lid 32 and the flange portion 31b of the case 31 and tightens it toward the inner diameter side may be employed as the attachment / detachment mechanism. The clamp ring 100 includes a ring 101 having a U-shaped cross section that sandwiches the flange portions 32 b and 31 b, a bolt 103 and a nut 104 that fasten the tightening portion 102 of the ring 101. If the clamp ring 100 is employed, the bolt 103 may be rotated, so that it can be easily attached and detached. Moreover, as shown in FIG. 10, a concave-convex fitting structure may be employed as the attachment / detachment mechanism. Instead of the flange portion 31 b of the case 31, a convex portion 110 protruding along the circumferential direction is provided inside the case 31, and the concave portion 111 is provided instead of the flange portion 32 b of the lid 32. Then, the case 31 is pressed toward the lid 32, and the convex portion 110 of the case 31 is fitted into the concave portion 111 of the lid 32. The case 31 may be provided with a concave portion, and the lid 32 may be provided with a convex portion. If the concave / convex fitting is employed, the case 31 can be attached to the lid 32 simply by fitting, so that it can be easily attached and detached. Moreover, you may provide the set screw which prevents rotation with respect to the lid | cover 32 of case 31. FIG.
  In the above embodiment, the heater 55 is inserted into the drain reservoir 54 through the insertion hole 56 and the drain is directly heated. However, as shown in FIG. 11, the housing 31 is provided in the case 31 for housing the heater 55. The case 31 may be heated. If it does in this way, the water | moisture content contained in a drain will be evaporated, the amount of drains can be reduced, the frequency | count of removing a case from a cover can be suppressed, and the lifetime of an attachment / detachment mechanism can be lengthened. Moreover, since the heater 55 does not touch the drain, it is possible to suppress the heater from being deteriorated by the drain.
  In the above embodiment, the introduction port 35 and the discharge port 40 are provided on the surface in the horizontal direction of the lid 32, but the introduction port 35 and the discharge port 40 are provided on a vertical surface such as the upper portion of the lid 32. Also good.
  In the above embodiment, the drain hose 34 is connected to the drain discharge port 33 of the case 31. However, the drain hose 34 may be omitted, and the drain discharge port 33 may be provided with a plug so as to discharge directly from the drain discharge port 33. Good. In this case, a drain outflow suppression member is provided at the drain discharge port 33.
  In the above embodiment, the first expansion chamber 45, the second expansion chamber 51, and the third expansion chamber 59 are provided in the oil separator 3, but any one of the first expansion chamber 45 and the second expansion chamber 51 is provided. May be omitted.
In the above embodiment, the drain hose 34 may be provided with a scale.
In the above embodiment, a member such as a nonwoven fabric filter may be disposed upstream or downstream of the urethane foam 50 or in the expansion chambers 45 and 51. In this way, the oil component removal rate can be improved. Further, the member such as the nonwoven fabric filter may be charged with static electricity. In this way, the oil component removal rate can be further improved.
  In the above embodiment, the urethane foam 50 is employed as the collision material, but other members such as crashed aluminum may be employed.
