Description

  The present invention is for an air dryer apparatus that separates and stores moisture, oil, dust, and the like from purge air during purge processing of the air dryer apparatus for removing moisture from service air used in service brakes, air suspensions, etc. in automobiles and the like. Regarding the catch tank.

For example, in large vehicles such as trucks and buses, air compressed to a predetermined pressure (for example, about 10 kgf / cm ² ) by an air compressor is stored in an air tank, and this compressed air (service air) is used as an operating power source. Service brake systems that are used as a part of the system and air suspension systems that use compressed air instead of coil springs and leaf springs are used.

Here, the air compressed by the air compressor is in a state where water is likely to be generated due to condensation of water vapor contained compared to the normal atmospheric pressure state.
In addition, there may be a case where lubricating oil for lubricating an air compressor including a crank mechanism and a piston that are rotationally driven by an engine is mixed in the compressed air.

  For this reason, if the air compressed by the air compressor is stored in the air tank as it is and the compressed air is supplied to various air systems such as a service brake system, corrosion or fouling occurs at the part where the compressed air comes into contact. As a result, there is a risk of adversely affecting the reliability of the system, for example, causing a malfunction in various air systems.

  For this reason, before the air compressed by the air compressor is stored in the air tank, it is dried by an air dryer device to remove oil and purify it.

As an example of such an air dryer device, there is one as described in Patent Document 1, for example, as shown in FIG. 12, when the air compressor 20 is in a load state where air is compressed (at the time of loading). Takes the compressed air into the air dryer device 10 from the inlet port 11, guides and passes the introduced compressed air to the filter 13 of the filter chamber 12, collects oil, dust, etc., and then guides it to the drying chamber 14. It is like that.
In the drying chamber 14, the moisture contained in the compressed air is absorbed and removed by the desiccant 15 accommodated in the drying chamber 14, and then the compressed air passes through the purge chamber 16 and the outlet 17 to the air tank 30. Has been led to.

On the other hand, when the pressure in the air tank 30 reaches a predetermined pressure (for example, about 10 kgf / cm ² ), the pressure regulator 40 operates and the air compressor 20 is brought into a no-load state (unload state) in which air is not compressed. However, in this state, the purge valve 18 is opened, and so-called purge processing is performed in which the compressed air in the purge chamber 16 is discharged to the outside while passing through the drying chamber 14 and the filter chamber 12.

  In addition, by this purging process, the moisture in the drying chamber 14 (the moisture adsorbed by the desiccant or the moisture accumulated in the bottom, etc.), the oil or dust in the filter chamber 12 (the oil collected in the filter 13, Dust and the like, and oil and dust collected at the bottom are discharged to the outside, and the desiccant 15 and the filter 13 are regenerated.

Japanese Utility Model Publication No. 5-26136 No. 7-8020 Japanese Utility Model Publication No. 6-76798 Japanese Utility Model Publication No. 7-10514

  By the way, when purge processing is performed to regenerate the desiccant 15 and the filter 13 using purge air at a predetermined pressure, moisture, oil, and the like accumulated in the air dryer device 10 are discharged from the drain 19 into the air and the ground along with the purge air. Since it is ejected toward the surface, there is a risk that the nearby wall or ground may be soiled, and it is desirable to prevent the moisture containing such oil from being inadvertently discharged to the outside.

  For this reason, in the air dryer device described in Patent Document 2 and Patent Document 3, purge air containing moisture and oil is guided to the drain tank, and the oil and moisture can be temporarily stored in the drain tank. As described above, the drain provided in the drain tank is released at an appropriate time and place, so that oil, moisture, and the like are not inadvertently discharged into the drain tank.

  Similarly, in the air dryer device described in Patent Document 4, purge air containing moisture and oil is guided to a casing (container), and the inside of the casing is partitioned by a partition plate provided with a plurality of small holes and a synthetic resin. By providing a fiber layer, a configuration is adopted in which only water that has been purified by collecting oil while purging sound is discharged to the outside together with purge air.

  However, a predetermined amount of purge air (for example, 4 L / second) needs to flow through the desiccant and the filter per unit time in order to regenerate the desiccant and the filter satisfactorily in the purge process. It is necessary to reduce the ventilation resistance of the drain tank. For this reason, in the air dryer apparatus described in Patent Document 2 or Patent Document 3 designed to have a relatively small ventilation resistance, the purge process is performed. Since the pressure of the purge air flowing into the drain tank is maintained at a relatively high level and is discharged to the outside with this high pressure, even if water and oil in the purge air can be temporarily stored in the drain tank. There is a risk that the purge air will be re-entrained and sprayed to the outside and discharged from the outlet.

  Moreover, in the air dryer apparatus described in Patent Document 4, even if the oil component can be removed, moisture is inadvertently discharged every time the purge process is performed, and the ventilation resistance of the casing may be increased. There is a possibility that it is difficult to obtain a desired purge performance.

  The present invention has been made in view of such a situation, and in spite of a simple and low-cost configuration, carelessly discharging moisture, oil, dust, etc. while maintaining desired purge performance with low airflow resistance. An object of the present invention is to provide a catch tank for an air dryer apparatus that has no adverse effects on the environment.

For this reason, the present invention

It is characterized by comprising.

  The present invention may be characterized in that a third chamber that is disposed below the bottom of the first chamber and stores at least moisture separated from the purge air is disposed.

  In the present invention, the outlet portion of the purge air introduction passage may be covered with a steam / water separation promoting element.

  According to the present invention, while having a simple and low-cost configuration, the ventilation resistance is small and the desired purge performance is maintained, and there is no adverse effect on the environment without inadvertently discharging moisture, oil or dust. It is possible to provide a catch tank for a few air dryer devices.

  Hereinafter, an embodiment of a catch tank for an air dryer apparatus according to the present invention will be described with reference to the accompanying drawings. In addition, this invention is not limited by embodiment described below.

As shown in FIG. 1, the catch tank 100 for an air dryer apparatus according to Example 1 of the present embodiment includes purge air (water, oil, dust, etc.) discharged from the drain 19 of the air dryer apparatus 10 during the purge process. For example, a pressure of about 10 kgf / cm ² and a unit time flow rate of about 4 L / second) are introduced into the inside through the inlet pipe 120. In addition, the description which abbreviate | omits the same element as the element already demonstrated is attached | subjected, and the description is abbreviate | omitted.

  2 is an enlarged cross-sectional view of the air dryer device catch tank 100 shown in FIG. 1, and FIG. 3 shows the air dryer device catch tank 100 (an example in which the catch tank 110 is transparent). It is the perspective view seen from diagonally upward.

  As shown in FIGS. 1 to 3, the inlet pipe 120 functioning as a purge air introduction passage is configured by a tubular member having a predetermined length, and an inlet end 120A is disposed on the upper side of the catch tank 100 for the air dryer device, and is disposed inside. The partition of the catch tank 110 having a space extends through the partition plate (first partition plate) 130 that vertically defines the catch tank 110 into the first chamber 110A and the second chamber 110B. The outlet end 120 </ b> B is arranged below the plate 130.

  A drain 19 of the air dryer apparatus 10 is connected to the inlet end 120A of the inlet pipe 120 via a resin hose or the like.

  Near the outlet end 120 </ b> B of the inlet pipe 120, a cap-shaped member 121 is placed on the outer periphery of the inlet pipe 120.

  The cap-shaped member 121 can be configured by a tubular member having one end closed and the other end open, and the open end is fixed by inserting the outlet end 120B of the inlet pipe 120. ing.

  Note that the bottom of the cap-shaped member 121 and the outlet end 120B of the inlet pipe 120 are attached with a predetermined gap, and the predetermined gap is located on the side of the cap-shaped member 121 (the longitudinal direction of the inlet pipe 120). A plurality of discharge holes (nozzles) 122 extending along a substantially orthogonal direction or a direction intersecting at a predetermined angle are opened. Note that the number, size, shape, layout, and the like of the discharge holes 122 can be changed as appropriate.

  Further, as shown in FIGS. 2 and 3, the partition plate 130 is provided with a plurality of through holes (penetrating portions) 131 for communicating the first chamber 110 </ b> A and the second chamber 110 </ b> B. Note that the number, size, shape, layout, and the like of the through holes 131 can be changed as appropriate.

  The second chamber 110B is provided with an external communication pipe (external communication portion) 140 that communicates the second chamber 110B with the outside. In FIG. 1 to FIG. 3, in order to obtain a labyrinth effect, one end of the external communication pipe 140 protrudes inward of the second chamber 110 </ b> B, and the external communication pipe 140 is connected to the through hole 131 of the partition plate 130. It extends in a direction intersecting with the penetration direction (a substantially orthogonal direction is illustrated in FIGS. 1 to 3). In FIG. 3, two external communication pipes 140 are provided facing each other, but the number, size, shape, layout, and the like of the external communication pipes 140 can be changed as appropriate.

  In the air dryer apparatus catch tank 100 having the above-described configuration, moisture is removed from the purge air (including moisture, oil, and dust) discharged from the drain 19 of the air dryer apparatus 10 during the purge process as follows. In addition, it is possible to separate only the purge air that does not contain moisture, oil, dust, etc.

  That is, the entire amount of purge air (including moisture, oil and dust) discharged from the drain 19 of the air dryer device 10 during the purge process is introduced into the air dryer device catch tank 100 via the inlet pipe 120. First, purge air flows from the inlet end 120A of the inlet pipe 120 toward the outlet end 120B.

  When the purge air guided to the outlet end 120 </ b> B exits from the outlet end 120 </ b> B, the direction of flow is controlled by the cap-shaped member 121, and the cross-section is substantially cylindrical via a discharge hole (nozzle) 122 provided in the cap-shaped member 121. Are injected in the radial direction with respect to the center axis of the inlet pipe 120 and the catch tank 110 and guided to the first chamber 110 </ b> A in the catch tank 110.

The purge air ejected vigorously through the discharge hole (nozzle) 122 collides with the inner wall (inner side wall) of the first chamber 110A, so that moisture, oil, dust, etc. contained in the purge air are discharged into the first chamber. Attached to the inner wall (inner side wall) of 110A, moisture, oil, dust, and the like are separated from the purge air (purge air containing moisture, oil, dust, etc. is separated from the air).
Water, oil, dust, etc. separated from the purge air are collected at the bottom of the first chamber 110A.

  Thereafter, only the purge air in the first chamber 110 </ b> A that has been separated from the steam is guided to the second chamber 110 </ b> B in the catch tank 110 through the through hole 131 provided in the partition plate 130.

  The purge air guided to the second chamber 110B is discharged to the outside through the external communication pipe 140 that connects the second chamber 110B and the outside.

  Since the purge air guided to the second chamber 110B passes through the through hole 131 and has an upward flow in FIGS. 1 to 3, the external communication pipe 140 is in a direction intersecting with the purge air flow direction ( In FIG. 1 to FIG. 3, the purge air is prevented from flowing directly into the external communication pipe 140 by extending in a substantially orthogonal direction (labyrinth effect).

  That is, even when the purge air contains moisture, oil, dust, etc. that could not be separated in the first chamber 110A, the purge air collides with the outer wall of the external communication pipe 140 or the inner wall of the second chamber 110B. By colliding, moisture, oil, dust, and the like can be separated from the purge air, and the purge air can be discharged to the outside through the external communication pipe 140 after the air-water separation.

  After the purge process, moisture, oil, dust, etc. separated from the purge air in the second chamber 110B are guided to the first chamber 110A through the through holes 131 of the partition plate 130 by natural dropping or the like, and the first It is joined to moisture, oil, dust, etc. stored at the bottom of the chamber 110A.

  By the way, as shown in FIG. 2 and the like, a drain cock 150 or the like can be provided at the bottom of the first chamber 110A, and water and oil stored in the bottom of the first chamber 110A at an appropriate place and timing.・ Dust etc. can be discharged, and moisture, oil, dust etc. will not be inadvertently discharged every time the purge process is performed, so there is a risk of soiling nearby walls and ground. Can be suppressed.

  As described above, according to the catch tank 100 for an air dryer apparatus according to the first embodiment, the purge chamber discharged from the air dryer apparatus 10 during the purging process is introduced and collided with the inner wall to achieve the air / water separation 110A. The purge plate is disposed above the first chamber 110A via the partition plate 130 and has been subjected to predetermined air-water separation by the first chamber 110A while suppressing re-entrainment of moisture, oil, dust, etc. A second chamber 110B introduced through 130 through-holes 131, and an external communication pipe 140 extending in a direction intersecting with the flow direction of the purge air introduced into the second chamber 110B (for example, a direction substantially orthogonal), Even if the moisture or oil in the purge air can be temporarily stored in the drain tank as in the past, the purge air is re-entrained and sprayed. This can reduce the risk that the air will be discharged from the discharge port to the outside, and the purge air can be efficiently separated during the purge process. It is possible to provide a catch tank for an air dryer device that does not discharge dust and the like and is advantageous to the surrounding pollution prevention and environment.

  Further, according to the catch tank 100 for an air dryer apparatus according to the present embodiment, the ventilation resistance of the purge air can be kept low, so that a desired purge performance can be obtained.

  That is, according to the catch tank 100 for an air dryer apparatus according to the present embodiment, the moisture resistance, the oil content, the dust, etc. are inadvertently maintained while maintaining a desired purge performance with a low airflow resistance while having a simple and low-cost configuration. Therefore, it is possible to provide a catch tank for an air dryer apparatus that does not discharge air and has little adverse effect on the environment.

  As shown in FIG. 4, an air / water separation promoting element 160 is disposed around the discharge hole (nozzle) 122 provided in the cap-shaped member 121, and the purge air passes through the air / water separation promoting element 160 while colliding with it. It is also possible to improve the air / water separation performance.

  As the air / water separation promoting element 160, a mesh such as a resin or metal, a porous material, a punching member (a member having a punched opening) such as a resin or metal, a metal filter net (for example, a metal scrubbing, etc.) Or the like in which a metal in a shape or a band is collected into a predetermined shape) can be employed (see FIG. 6).

  In addition, as shown in FIG. 5, instead of the cap-shaped member 121, an air / water separation promoting container 170 containing the air / water separation promoting element 160 is arranged to cover the outlet of the inlet pipe 120. You can also. An opening can be provided in the wall of the steam / water separation promoting container 170 so that purge air is ejected from the steam / water separation promoting container 170 to the side. Although FIG. 5 shows a case where the air is ejected toward the side, the purge air can be ejected toward one or both of the side and the lower side.

  As in the case of the first embodiment, the catch tank 200 for the air dryer device according to the second embodiment of the present embodiment removes purge air (water, oil, dust, etc.) discharged from the drain 19 of the air dryer device 10 during the purge process. Are included) through the inlet pipe 120. In addition, the description about the already demonstrated code | symbol is abbreviate | omitted as attaching | subjecting the same code | symbol to the same element.

  As shown in FIG. 7, the catch tank 200 for an air dryer device according to the second embodiment includes a third chamber 110 </ b> C defined via a partition plate (second partition plate) 210 below the first chamber 110 </ b> A. Is provided.

  The partition plate 210 is provided with a through hole (penetrating portion) 211, and moisture, oil or dust separated from the purge air in the first chamber 110 </ b> A (or the second chamber 110 </ b> B) passes through the through hole 211. The third chamber 110C is dropped and accommodated.

  A drain cock 150 or the like can be provided at the bottom of the third chamber 110C, and water, oil, dust, etc. stored in the bottom of the third chamber 110C can be discharged at an appropriate location and timing. As in the prior art, water, oil, dust, and the like are not inadvertently discharged every time the purge process is performed, so that the risk of soiling nearby walls or the ground can be suppressed.

  As described above, according to the catch tank 200 for an air dryer device according to the second embodiment configured with the third chamber 110C, compared to the first embodiment, the air is stored at the bottom of the first chamber 110A during the purge process. The moisture, oil, dust, etc. that are trapped in the purge air can be suppressed, so that the moisture, oil, dust, etc. are transported to the outside of the second chamber 110B to the external communication pipe 140 and discharged to the outside. It is possible to more reliably suppress the risk of being lost.

  In the case of the second embodiment, it is possible to suppress the possibility that water, oil, dust, etc. separated from the purge air in the first chamber 110A will be caught in the purge air again. The communication pipe 140 may be omitted, and an opening 220 that opens directly to the wall of the second chamber 110B may be provided. The number, size, shape, layout, and the like of the openings 220 can be appropriately changed. For example, the openings 220 can be arranged on one or both of the side wall and the upper wall of the second chamber 110B.

  The air dryer apparatus catch tank 300 according to Example 3 of the present embodiment is purge air (including moisture, oil, dust, etc.) discharged from the drain 19 of the air dryer apparatus 10 during the purge process, as in Example 1. Is introduced into the interior through the inlet pipe 320. In addition, the description about the already demonstrated code | symbol is abbreviate | omitted as attaching | subjecting the same code | symbol to the same element.

  Here, in the air dryer apparatus catch tank 100 (200) according to the first embodiment or the second embodiment, the purge air after the air / water separation in the first chamber 110A is guided to the upper second chamber 110B. At this time, the gas passes between the outer periphery of the inlet pipe 120 inserted from above and the inner wall of the catch tank 110.

  The flow rate of the relatively high-pressure purge air is affected by the size of the gap between the periphery of the inlet pipe 120 and the inner wall of the catch tank 110, and it is difficult to make the gap large due to restrictions such as installation space. The purge air passage cross-sectional area becomes small and the speed becomes relatively high. In such a case, the purge air once again gets trapped in the first chamber 110A and is discharged to the outside. is assumed.

  For this reason, in Example 3, as shown in FIG. 9, the inlet pipe 320 was inserted from the third chamber 110C side and connected to the steam / water separation promoting container 170 in the first chamber 110A.

  With this configuration, the flow rate of the purge air in the first chamber 110A can be effectively reduced in the third embodiment as compared with the second embodiment. Therefore, the water, oil, and dust once separated in the first chamber 110A can be reduced. There is a risk that dust or the like is caught in the purge air and is carried to the second chamber 110B side, and moisture, oil or dust is inadvertently discharged to the outside through the opening 220 or the like during the purge process. It can suppress more effectively.

  As shown in FIG. 10, when the opening 220 is provided on the upper wall of the second chamber 110B, it has passed through the opening 220 so that moisture, oil, dust, and the like are not directly discharged to the outside. It is also possible to employ a configuration in which a cover member 330 that collides with purge air and exerts an air-water separation action is provided.

  Also, as shown in FIG. 10, the inlet pipe 320 is bent in a substantially orthogonal direction and overlapped with the third chamber 110C when viewed from a direction substantially orthogonal to the plane of FIG. It is also possible to improve the degree of freedom of mounting on the vehicle by shortening the length.

  As described above, according to the catch tanks 200 and 300 for the air dryer apparatus according to the second and third embodiments, the purge air discharged during the purge process of the air dryer apparatus 10 is introduced and collided with the inner wall to separate the air and water. The first chamber 110A and the purge air that is disposed above the first chamber 110A via the partition plate 130 and has been subjected to predetermined air-water separation by the first chamber 110A is re-entrained with moisture, oil, dust, etc. A second chamber 110B that is introduced through the through hole 131 of the partition plate 130 while suppressing water, and a third chamber 110C that introduces and stores moisture, oil, dust, and the like separated from the purge air in the first chamber 110A. And the opening 220 for discharging the purge air introduced into the second chamber 110B to the outside, as in the prior art, the moisture and oil content in the purge air is contained in the drain tank. However, once the purge air has been stored, it is possible to suppress the risk that the purge air will be re-entrained and become sprayed and discharged from the discharge port to the outside. Thus, it is possible to provide a catch tank for an air dryer device that can achieve air / water separation, and therefore does not inadvertently discharge moisture, oil, dust, and the like, and is advantageous for prevention of surrounding contamination and environment.

  Further, according to the catch tanks 200 and 300 for the air dryer device according to the second and third embodiments, the purge air ventilation resistance can be kept low, so that a desired purge performance can be obtained.

  That is, according to the catch tanks 200 and 300 for the air dryer apparatus according to the second and third embodiments, the moisture resistance and the oil content are inadvertently maintained while maintaining a desired purge performance with a low airflow resistance while having a simple and low-cost configuration. -It is possible to provide a catch tank for an air dryer device that does not discharge dust or the like and has little adverse effect on the environment.

  In the second and third embodiments, the third chamber 110C has been described as a configuration connected to the lower side of the first chamber 110A via the partition plate 210. However, the present invention is not limited to this, As shown in FIG. 11, it is also possible to employ a third chamber 110C that is separated from the first chamber 110A via a communication passage 410 using a pipe, a hose, or the like.

  By the way, the catch tank 110 according to each of the above-described embodiments can be manufactured using, for example, a transparent material so that the amount of collected moisture, oil, dust, and the like can be easily confirmed. In addition, it can be easily attached to and detached from vehicles, etc. so that workers and users can easily dispose of collected water, oil, dust, etc. by removing it and turning it upside down. Can be configured.

  The embodiment described above is merely an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
