Description

Technical Field

[0001] This utility model belongs to the technical field of air supply devices, specifically relating to a high-pressure air dryer and an air suspension air supply system. Background Technology

[0002] In related technologies, air suspension air supply systems typically use a dryer at the system's air inlet to dry the air entering the system. However, the lack of a dryer inside the system results in poor air drying. As the dryer at the system inlet is used for a long time, its drying effect will further deteriorate, which is detrimental to the protection of the equipment inside the system. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a high-pressure air dryer suitable for drying gases within a gas supply system.

[0004] An embodiment of this utility model also proposes an air suspension air supply system.

[0005] The high-pressure air dryer of this utility model embodiment includes: a housing having a first end and a second end, the first end of the housing having a first air port, and the second end of the housing having a second air port, the second air port and the first air port being interconnected; a desiccant disposed inside the housing, the two ends of the desiccant corresponding to the first air port and the second air port respectively; a first ventilated clamping assembly disposed at the first end; a second ventilated clamping assembly disposed at the second end and cooperating with the first ventilated clamping assembly to clamp the desiccant; and an air guide tube penetrating the desiccant, the air guide tube being connected to the first air port through the first ventilated clamping assembly and to the second air port through the second ventilated clamping assembly.

[0006] Understandably, by setting a first air port and a second air port on the casing, external gas can enter through the first air port and exit through the second air port, or vice versa. The gas entering the casing is then dried by the desiccant. When the desiccant fails, it can be cleared through the vent pipe, preventing blockages caused by desiccant failure and ensuring normal gas supply. This makes it suitable for air drying within the gas supply system, improving the drying effect. Furthermore, the first and second vent clamping components at both ends of the desiccant isolate it from the external gas, extending its service life.

[0007] In this embodiment, the first air port is located on the side wall of the housing; and / or, the second air port is located on the side wall of the housing.

[0008] In this embodiment, a first air pipe connector is provided at the first air port; and / or, a second air pipe connector is provided at the second air port.

[0009] In this embodiment, a connecting seat is provided on the outer wall of the housing, and a connecting member is provided on the connecting seat.

[0010] In this embodiment, the first breathable clamping assembly includes a first breathable felt and a first gasket. The first breathable felt is disposed on the end face of the desiccant, and the first gasket is located on the side of the first breathable felt away from the desiccant.

[0011] In this embodiment, the second breathable clamping assembly includes a second breathable felt, a second gasket, an elastic element, and an end cap, arranged sequentially from the end face of the desiccant towards the direction away from the desiccant.

[0012] The air suspension air supply system in this embodiment includes a valve body, an air supply unit, a low-pressure air dryer, the aforementioned high-pressure air dryer, and an air tank. The air supply unit is disposed on the valve body, the low-pressure air dryer is disposed on the air inlet pipe of the air supply unit, the air tank is connected to the air supply unit, and the high-pressure air dryer is disposed on the pipe between the air supply unit and the air tank.

[0013] In this embodiment, the housing is detachably connected to the valve body.

[0014] In this embodiment, the side wall of the housing is provided with a mounting plane, and the housing abuts against the side wall of the valve body through the mounting plane.

[0015] In this embodiment, the air suspension air supply system also includes a muffler, which is connected to the air inlet of the low-pressure air dryer and to the atmosphere. Attached Figure Description

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the high-pressure air dryer 1 includes a housing 11, a desiccant 12, a first ventilated clamping assembly 13, a second ventilated clamping assembly 14, and an air guide pipe 15. The housing 11 has a first end and a second end. The first end of the housing 11 is provided with a first air port 111, and the second end of the housing 11 is provided with a second air port 112, which communicates with the first air port 111. The desiccant 12 is disposed inside the housing 11, with its two ends corresponding to the first air port 111 and the second air port 112, respectively. The first ventilated clamping assembly 13 is disposed at the first end; the second ventilated clamping assembly 14 is disposed at the second end and cooperates with the first ventilated clamping assembly 13 to clamp the desiccant 12. The air guide pipe 15 passes through the desiccant 12, and the air guide pipe 15 communicates with the first air port 111 through the first ventilated clamping assembly 13 and with the second air port 112 through the second ventilated clamping assembly 14.

[0028] Specifically, the housing 11 has a mounting cavity, and the desiccant 12 is disposed within the mounting cavity. An open opening communicating with the mounting cavity may be provided on the housing 11, through which the desiccant 12, the first ventilated clamping assembly 13, and the second ventilated clamping assembly 14 are installed within the mounting cavity of the housing 11. Further, the second ventilated clamping assembly 14 may seal the open opening, so that external gas enters or exits only through the first air port 111 and the second air port 112.

[0029] It is understandable that by providing a first air port 111 and a second air port 112 on the housing 11, external gas can be introduced through the first air port 111 and exhausted through the second air port 112, or vice versa. The gas entering the housing 11 is then dried by the desiccant 12. When the desiccant 12 fails, it can be cleared through the air guide pipe 15, preventing blockage caused by the desiccant 12's failure and ensuring normal gas supply. This allows for air drying within the gas supply system, improving the drying effect. Furthermore, the first ventilated clamping assembly 13 and the second ventilated clamping assembly 14 at both ends of the desiccant 12 isolate it from the gas outside the housing 11, thus extending its service life.

[0030] In this embodiment, the first air port 111 is located on the side wall of the housing 11. And / or, the second air port 112 is located on the side wall of the housing 11.

[0031] It should be noted that when the first air port 111 is located on the side wall of the housing 11, the second air port 112 can be located on either the side wall or the end of the housing 11. The first air port 111 and the second air port 112 can also be located simultaneously on the side wall of the housing 11. The positions of the first air port 111 and the second air port 112 can be set as needed and are not limited here.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, a first air pipe connector 16 is provided at the first air port 111. And / or, a second air pipe connector 17 is provided at the second air port 112.

[0033] It should be noted that a first air pipe connector 16 can be set at the first air port 111, or at the second air port 112, or a first air pipe connector 16 and a second air pipe connector 17 can be set at the first air port 111 and the second air port 112 respectively. By setting air pipe connectors, it is convenient to connect the high-pressure air dryer 1 to the pipeline through the first air pipe connector 16 or the second air pipe connector 17, thereby facilitating the connection of the high-pressure air dryer 1.

[0034] In this embodiment, as Figure 1 As shown, a connecting seat 113 is provided on the outer wall of the housing 11, and a connecting member 18 is provided on the connecting seat 113.

[0035] For example, the connector 113 can be integrally formed with the housing 11, which can improve the connection strength between the connector 113 and the housing 11 and save the connection process between the two. Of course, the connector 113 can also be separately formed from the housing 11 and then connected. The connection method between the connector 113 and the housing 11 can be selected as needed and is not limited here.

[0036] The housing 11 may be provided with one or more connecting seats 113 as needed for installation, and each connecting seat 113 is provided with a corresponding connector 18.

[0037] Specifically, the connector 18 can be a bolt, and the connector 113 has a connecting hole through which the connector 18 passes. When it is necessary to fix the housing 11, it can be fixed by bolts.

[0038] It is understandable that by providing a connecting seat 113 on the outer wall of the housing 11 and a connecting member 18 on the connecting seat 113, the housing 11 can be easily installed via the connecting member 18.

[0039] In this embodiment, as Figure 2 As shown, the first breathable clamping assembly 13 includes a first breathable felt 131 and a first gasket 132. The first breathable felt 131 is disposed on the end face of the desiccant 12, and the first gasket 132 is located on the side of the first breathable felt 131 away from the desiccant 12.

[0040] Specifically, the first gasket 132 is provided with a first connecting protrusion, which is inserted into the first breathable felt 131. The first gasket 132 and the first breathable felt 131 can be connected as one unit through the first connecting protrusion, which facilitates installation.

[0041] When the first air port 111 is located on the side wall of the housing 11, a support portion is provided on the side of the first gasket 132 facing away from the first breathable felt 131 to form a gap between the first gasket 132 and the inner wall of the housing 11, and the first air port 111 connects to the gap. External gas can enter the gap through the first air port 111, and then pass through the first breathable clamping assembly 13, the desiccant 12 and the second breathable clamping assembly 14 in sequence.

[0042] In this embodiment, the first breathable clamping assembly 13, by setting the first breathable felt 131 and the first gasket 132, allows gas to pass through while preventing the desiccant 12 from directly contacting the air, which is beneficial to improving the service life of the desiccant 12.

[0043] In this embodiment, as Figure 1 and Figure 2As shown, the second breathable clamping assembly 14 includes a second breathable felt 141, a second gasket 142, an elastic element 143, and an end cap 144 arranged sequentially from the end face of the desiccant 12 away from the desiccant 12.

[0044] For example, the second gasket 142 has a second connecting protrusion on the side facing the second breathable felt 141. The second connecting protrusion is inserted into the second breathable felt, and the second gasket and the second breathable felt can be connected as one unit through the second connecting protrusion, which can facilitate installation.

[0045] The elastic element 143 can be a spring. The end cap 144 has an annular groove facing the first gasket 132. One end of the spring abuts against the first gasket 132, and the other end of the spring abuts against the bottom wall of the annular groove. The annular groove can limit the elastic element 143, thereby facilitating the installation of the elastic element 143.

[0046] Specifically, a sealing ring is provided between the outer wall of the end cap 144 and the inner wall of the housing 11 to improve the sealing effect between the end cap 144 and the housing 11.

[0047] It should be noted that by setting the second breathable felt 141 and the second gasket 142, air can pass through while the desiccant 12 is isolated from the outside air, thus reducing the service life of the desiccant 12. The elastic element 143 is set between the end cap 144 and the second gasket 142, which allows the desiccant 12 to have a certain expansion space when it absorbs water and expands. At the same time, under the limiting action of the spring by the end cap 144, the elastic element 143 can always be pressed against the second gasket 142, thereby applying pressure to the desiccant 12 through the second breathable felt 141 and the second gasket 142 to fix the desiccant 12.

[0048] like Figure 3 As shown, the air suspension air supply system in this embodiment includes a valve body 2, an air supply unit 3, a low-pressure air dryer 4, the aforementioned high-pressure air dryer 1, and an air storage tank (not shown in the figure). The air supply unit 3 is disposed on the valve body 2, the low-pressure air dryer 4 is disposed on the air inlet pipe of the air supply unit 3, the air storage tank is connected to the air supply unit 3, and the high-pressure air dryer 1 is disposed on the pipe between the air supply unit 3 and the air storage tank.

[0049] Specifically, the first air pipe connector 16 of the high-pressure air dryer 1 is connected to the air supply unit 3 via a pipeline, and the second air pipe connector 17 of the high-pressure air dryer 1 is connected to the air storage tank. The composition and connection method of the air supply unit 3 is conventional prior art and will not be described in detail here. The air supply unit 3 is connected to the air spring via the third air pipe connector 5.

[0050] It should be noted that when the air tank needs replenishment, the low-pressure air dryer 4 is controlled to intake air. The low-pressure air dryer 4 dries the air, and then the gas is controlled to enter the high-pressure air dryer 1 through the air supply unit 3 for secondary drying before replenishing the air tank. When it is necessary to control the air suspension to rise or fall, the low-pressure air dryer 4 does not operate, and the dried gas in the air tank is controlled to enter the air spring connected to the air supply unit 3, thus raising the air suspension. When the gas in the air spring is controlled to enter the air tank through the high-pressure air dryer 1, the air suspension falls.

[0051] In this embodiment, the housing 11 is detachably connected to the valve body 2.

[0052] Specifically, when connecting the housing 11 to the valve body 2, the housing 11 is connected to the valve body 2 through the connector 18. For example, when the connector 18 is a bolt, the valve body 2 is provided with a corresponding connection hole, and the connector 18 is threaded into the connection hole, so that the housing 11 is fixed to the valve body 2 through the cooperation of the connector 18 and the connection hole.

[0053] It is understandable that detachably connecting the housing 11 to the valve body 2 facilitates the installation and disassembly of the housing 11, thereby facilitating the maintenance, replacement, or replacement of the desiccant 12 in the high-pressure air dryer 1.

[0054] In this embodiment, as Figure 1 and Figure 3 As shown, the side wall of the housing 11 is provided with a mounting plane 114, and the housing 11 abuts against the side wall of the valve body 2 through the mounting plane 114.

[0055] Understandably, by setting the mounting plane 114, the high-pressure air dryer 1 can fit better with the valve body 2, which helps to make the overall structure more compact.

[0056] In this embodiment, as Figure 3 As shown, the air suspension air supply system also includes a muffler 6, which is connected to the air inlet of the low-pressure air dryer 4 and to the atmosphere.

[0057] Understandably, by setting up the silencer 6, the noise generated when gas enters the valve body 2 through the low-pressure dryer can be effectively reduced, thus improving the overall quietness of the system.
