DETAILED DESCRIPTION
[0023] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0024] In the present embodiment, as shown in Figure 1 and Figure 2 , the integrated dryer comprises a low pressure dryer body 1 and a high pressure dryer body 2. The low pressure dryer body 1 has a first two-way air port 1341 and a second two-way air port 15 which are in communication with each other, and the first two-way air port 1341 is adapted to communicate with external air. The high pressure dryer body 2 is connected to the low pressure dryer body 1, and the high pressure dryer body 2 has a third two-way air port 2341 and a fourth two-way air port 25 which are in communication with each other, and the third two-way air port 2341 and the fourth two-way air port 25 are adapted to be connected in series to the inlet of the gas storage tank.
[0025] Specifically, the first bidirectional air port 1341 and the second bidirectional air port 15 of the low-pressure dryer body 1 are respectively located at two ends of the air flow conveying direction in the low-pressure dryer body 1, and the first bidirectional air port 1341 and the second bidirectional air port 15 are both bidirectional air ports, so that the air can be conveyed from the side of the first bidirectional air port 1341 to the side of the second bidirectional air port 15, or from the side of the second bidirectional air port 15 to the side of the first bidirectional air port 1341. Similarly, the third bidirectional air port 2341 and the fourth bidirectional air port 25 of the high-pressure dryer body 2 are respectively located at two ends of the air flow conveying direction in the high-pressure dryer body 2, and the third bidirectional air port 2341 and the fourth bidirectional air port 25 are both bidirectional air ports, so that the air can be conveyed from the side of the third bidirectional air port 2341 to the side of the fourth bidirectional air port 25, or from the side of the fourth bidirectional air port 25 to the side of the third bidirectional air port 2341.
[0026] It can be understood that the integrated dryer includes the low-pressure dryer body 1 and the high-pressure dryer body 2 connected to each other, the low-pressure dryer can be arranged at the inlet of the air supply system to preliminarily dry the air, and the air preliminarily dried can be pressurized by the air supply system, and the high-pressure dryer can be arranged in the air supply system to further dry the air pressurized, so that the drying effect of the air can be improved, and when the low-pressure dryer body 1 at the inlet of the air supply system fails, the air can be dried by the high-pressure dryer body 2, thereby providing double guarantee for the drying of the air. In addition, the low-pressure dryer body 1 and the high-pressure dryer body 2 can both be bidirectionally ventilated, so that the low-pressure dryer body 1 and the high-pressure dryer body 2 can be back-flushed, which is beneficial to prolong the service life of the drying agent in the low-pressure dryer body 1 and the high-pressure dryer body 2 and reduce the replacement frequency of the drying agent.
[0027] In the embodiment, as shown in Figure 1 and Figure 2 , the low-pressure dryer body 1 includes a first shell 11, a first drying agent 12, a first elastic air-permeable clamping assembly 13, and a first fixed air-permeable clamping assembly 14. The first shell 11 has a first installation cavity with one end being open. The first drying agent 12 is arranged in the first installation cavity. The first elastic air-permeable clamping assembly 13 is arranged at the open end of the first shell 11 and abuts against the first drying agent 12, and the first bidirectional air port 1341 is arranged on the first elastic air-permeable clamping assembly 13. The first fixed air-permeable clamping assembly 14 is arranged in the first shell 11 and located at one end of the first drying agent 12 away from the first elastic air-permeable clamping assembly 13, and the second bidirectional air port 15 is arranged on the end face of the same end of the first shell 11 and the first fixed air-permeable clamping assembly 14.
[0028] Exemplarily, the end face of the first shell 11 is formed with a first air nozzle 111, the first air nozzle 111 has a first inner passage in communication with the first mounting cavity of the first shell 11, and the first inner passage forms the second bidirectional air port 15. The first elastic air-permeable clamping assembly 13 is provided with a second air nozzle, the second air nozzle has a second inner passage in communication with the first mounting cavity of the first shell 11, and the second inner passage forms the first bidirectional air port 1341.
[0029] It can be understood that the first shell 11 has a first mounting cavity for mounting the first desiccant 12, and the first elastic air-permeable clamping assembly 13 and the first fixed air-permeable clamping assembly 14 are respectively arranged at two ends of the first desiccant 12. The first desiccant 12 can be limited by the first elastic air-permeable clamping assembly 13 and the first fixed air-permeable clamping assembly 14, and the first desiccant 12 is isolated from the external air, which is beneficial to improve the service life of the first desiccant 12. In addition, the first elastic air-permeable clamping assembly 13 arranged at one end of the first desiccant 12 not only limits the first desiccant 12, but also provides a certain expansion space for the first desiccant 12, thereby improving the water absorption capacity of the first desiccant 12.
[0030] In the embodiment, as shown in Figure 1 and Figure 2 The first elastic air-permeable clamping assembly 13 includes, from inside to outside of the first shell 11, a first air-permeable felt 131, a bidirectional valve 132, a first elastic member 133, and a first end cover 134. The first end cover 134 is detachably connected to the first shell 11. The bidirectional valve 132 has at least two one-way valve ports, and at least one one-way valve port is opposite to at least another one-way valve port in flow direction. The first bidirectional air port 1341 is arranged on the first end cover 134.
[0031] For example, the first elastic member 133 is a spring. Further, at least one of the opposite two end faces of the bidirectional valve 132 and the first end cover 134 is provided with a first limiting protrusion. That is, the first limiting protrusion can be arranged on the bidirectional valve 132, or on the first end cover 134, or on both the bidirectional valve 132 and the first end cover 134. The first elastic member 133 is sleeved on the first limiting protrusion, and the first limiting protrusion can limit and guide the first elastic member 133, thereby facilitating reliable limiting of the first elastic member 133.
[0032] For example, the outer peripheral wall of the first end cover 134 is provided with a clamping groove, and the inner wall of the first shell 11 is provided with a clamping protrusion corresponding to the position of the clamping groove. The first end cover 134 and the first shell 11 can be clamped by the clamping protrusion and the clamping groove, thereby facilitating installation and dismounting of the first end cover 134. That is, after the first end cover 134 is dismounted from the first shell 11, the first elastic member 133, the bidirectional valve 132, and the first air-permeable felt 131 are taken out in sequence, and the first desiccant 12 can be replaced.
[0033] The first elastic air-permeable clamping assembly 13 in the embodiment can isolate the first desiccant 12 from the outside air while allowing air to permeate by providing the first air-permeable felt 131. By providing the bidirectional valve 132, the one-way valve port can be closed in the non-working state, so that the desiccant is isolated from the air, and the air intake and exhaust requirements can be met in the working state. By providing the first elastic member 133, the first air-permeable felt 131 and the bidirectional valve 132 have a certain displacement space, so that the first desiccant 12 has a certain expansion space to better remove the moisture in the air. The first end cover 134 is detachably connected with the first shell 11, so that the first end cover 134 can be removed to replace the first desiccant 12.
[0034] In the embodiment, as shown in Figures 2 to 4 The bidirectional valve 132 includes a valve seat 1321 and elastic blocking members 1322. The valve seat 1321 is provided with mounting holes. The elastic blocking members 1322 are provided in two, and each is mounted in a mounting hole. The elastic blocking members 1322 include mounting portions and arc-shaped elastic pieces connected with each other. The mounting portions are mounted in the mounting holes. In the direction of air flow, the valve seat 1321 is provided with air-permeable holes 13212 corresponding to the arc-shaped elastic pieces. The arc-shaped elastic pieces have a blocking state and an open state. In the blocking state, the arc-shaped elastic pieces abut against the valve seat 1321 to block the air-permeable holes 13212. In the open state, the arc-shaped elastic pieces are separated from the valve seat 1321 to open the air-permeable holes 13212.
[0035] Specifically, as shown in Figures 2 to 4 The arc-shaped elastic pieces are circular arcs. When the arc-shaped elastic pieces are not subjected to external pressure, the circumferential edges of the arc-shaped elastic pieces are attached to the end surface of the valve seat 1321. The projection of the arc-shaped elastic pieces in the axial direction overlaps the projection of the air-permeable holes 13212 in the axial direction. Thus, when the arc-shaped elastic force is separated from the valve seat 1321 due to external pressure, air can pass through the gap between the arc-shaped elastic pieces and the end surface of the valve seat 1321 through the air-permeable holes 13212. Further, the mounting portions are cylindrical, and the arc-shaped elastic pieces are arranged at one end of the mounting portions. The end of the mounting portions away from the arc-shaped elastic pieces is a circular conical table. The maximum outer diameter of the circular conical table is greater than the outer diameter of the middle part of the mounting portions. Thus, the mounting portions can be inserted into the mounting holes and reliably fixed in the mounting holes. The two elastic blocking members 1322 are located on both sides of the valve seat 1321. When one of the elastic blocking members 1322 is in the working state, the other can be in the non-working state.
[0036] It can be understood that, in the embodiment, the valve seat 1321 and the elastic sealing piece 1322 are arranged, the mounting hole and the air hole 13212 are arranged on the valve seat 1321, the elastic sealing piece 1322 is mounted in the mounting hole, the arc-shaped elastic piece of the elastic sealing piece 1322 has a sealing state and an opening state, in the sealing state, the arc-shaped elastic piece can seal the air hole 13212, so that the gas cannot pass through the valve seat 1321, in the opening state, the arc-shaped elastic piece can open the air hole 13212, so that the gas can pass through the valve seat 1321, by arranging two elastic sealing pieces 1322, only one is in working state when pressure is applied in one direction, and air cannot pass through when pressure is not applied in two directions, so that the bidirectional valve 132 can isolate external air in a non-working state.
[0037] In the embodiment, as shown in Figure 2 and Figure 4 , the valve seat 1321 is provided with a first connecting protrusion 13211 on the side facing the first air-permeable felt 131, and the first connecting protrusion 13211 is inserted into the first air-permeable felt 131.
[0038] It can be understood that, by inserting the first connecting protrusion 13211 on the valve seat 1321 into the first air-permeable felt 131, the valve seat 1321 and the first air-permeable felt 131 are connected to each other, which can facilitate simultaneous installation and disassembly of the valve seat 1321 and the first air-permeable felt 131.
[0039] In the embodiment, as shown in Figure 2 , the first fixed air-permeable clamping assembly includes a second air-permeable felt 141 and a first gasket 142, and the second air-permeable felt 141 is arranged in the first shell 11; the first gasket 142 is arranged on the side of the second air-permeable felt 141 away from the first elastic air-permeable clamping assembly 13.
[0040] Specifically, the first gasket 142 is provided with a second connecting protrusion on the side facing the second air-permeable felt 141, and the second connecting protrusion is inserted into the second air-permeable felt 141, so that the first gasket 142 and the second air-permeable felt 141 are connected as a whole, which can facilitate simultaneous installation and disassembly of the first gasket 142 and the second air-permeable felt 141.
[0041] It can be understood that, by arranging the second air-permeable felt 141 and the first gasket 142, the first fixed air-permeable clamping assembly can limit the first drying agent 12 while allowing air to pass through the second air-permeable felt 141 and the first gasket 142.
[0042] In the embodiment, as shown in Figure 2As shown, the high-pressure dryer body 2 comprises a second shell 21, a second drying agent 22, a second elastic air-permeable clamping assembly 23 and a second fixed air-permeable clamping assembly 24. The second shell 21 has a second mounting cavity with one end being open. The second drying agent 22 is arranged in the second mounting cavity. The second elastic air-permeable clamping assembly 23 is arranged at the open end of the second shell 21 and abuts against the second drying agent 22. A third bidirectional air port 2341 is arranged on the second elastic air-permeable clamping assembly 23. The second fixed air-permeable clamping assembly 24 is arranged in the second shell 21 and located at one end of the second drying agent 22 away from the second elastic air-permeable clamping assembly 23. A fourth bidirectional air port 25 is arranged on the end face of the same end of the second shell 21 and the second fixed air-permeable clamping assembly 24.
[0043] It can be understood that the second shell 21 has a second mounting cavity for mounting the second drying agent 22. The second elastic air-permeable clamping assembly 23 and the second fixed air-permeable clamping assembly 24 are arranged at two ends of the second drying agent 22 respectively. The second drying agent 22 is limited by the second elastic air-permeable clamping assembly 23 and the second fixed air-permeable clamping assembly 24, and is separated from the external air, which is beneficial to improve the service life of the second drying agent 22. In addition, the second elastic air-permeable clamping assembly 23 arranged at one end of the second drying agent 22 provides a certain expansion space for the second drying agent 22 while limiting the second drying agent 22, thereby improving the ability of the second drying agent 22 to remove water in the air.
[0044] In the embodiment, as shown in Figure 2 The second elastic air-permeable clamping assembly 23 comprises a third air-permeable felt 231, a second gasket 232, a second elastic member 233, a second end cover 234 and a first air pipe joint 235 arranged in the second shell 21 from inside to outside in sequence. The second end cover 234 is detachably connected with the second shell 21. The second end cover 234 is provided with a first connecting hole. The first air pipe joint 235 is connected in the first connecting hole. The third bidirectional air port 2341 is arranged on the first air pipe joint 235.
[0045] Specifically, the second gasket 232 is provided with a third connecting protrusion on the side facing the third air-permeable felt 231. The third connecting protrusion is inserted into the third air-permeable felt 231, so that the third air-permeable felt 231 and the second gasket 232 are connected as a whole, which is convenient for simultaneous installation and disassembly of the two.
[0046] For example, the second elastic member 233 is a spring. At least one of the two opposite end faces of the second gasket 232 and the second end cover 234 is provided with a second limiting protrusion, that is, the second limiting protrusion can be provided on the second gasket 232, or on the second end cover 234, or on both the second gasket 232 and the second end cover 234. The second elastic member 233 is sleeved on the second limiting protrusion, and the second limiting protrusion can limit and guide the second elastic member 233, facilitating reliable limiting of the second elastic member 233.
[0047] Specifically, the second end cover 234 and the second shell 21 are detachably connected by bolts. Connecting the second end cover 234 and the second shell 21 by bolts can improve the connection strength of the two, so as to adapt to a high-pressure environment.
[0048] The second elastic air-permeable clamping assembly 23 in the embodiment limits the second desiccant 22 by sequentially arranging the third air-permeable felt 231, the second gasket 232, the second elastic member 233, and the second end cover 234 from inside to outside of the second shell 21, and at the same time, the second desiccant 22 has a certain expansion space. By arranging the first air pipe joint 235 on the second end cover 234, the one end of the high-pressure dryer body 2 can be reliably connected with the air pipe.
[0049] In the embodiment, as shown in Figure 2 The high-pressure dryer body 2 further includes a second air pipe joint, and the second air pipe joint is connected to the fourth bidirectional air port 25.
[0050] Similarly, the fourth bidirectional air port 25 is connected with the second air pipe joint, which can facilitate the connection of the other end of the high-pressure dryer body 2 with the air pipe.
[0051] In the embodiment, as shown in Figure 2 The second fixed air-permeable clamping assembly 24 includes a fourth air-permeable felt 241 and a third gasket 242, and the third gasket 242 is located on the side of the fourth air-permeable felt 241 away from the second desiccant 22. The third gasket 242 is provided with a fourth connecting protrusion toward the fourth air-permeable felt 241, so as to connect the fourth air-permeable felt 241 and the third gasket 242 together through the fourth protrusion.
[0052] The first shell 11 and the second shell 21 in the embodiment can be integrally formed or connected through a connecting piece. When the first shell 11 and the second shell 21 are connected through the connecting piece, the connecting piece can relatively fix the first shell 11 and the second shell 21 or relatively rotate by a certain angle, and therefore the specific form of the connecting piece can be selected by the person skilled in the art according to the need, which is not limited herein. Of course, the connecting mode of the first shell 11 and the second shell 21 is not used to limit the utility model, and the connecting mode of the first shell 11 and the second shell 21 can be determined according to the installation scene, which is not limited herein.
