[0034] Reference below Figure 1-Figure 2 The drying device 100 according to the embodiment of the utility model is described. A connecting portion 15 is provided between two adjacent drying cylinders 11 spaced apart from each other in the outer shell 1, and a connecting hole 21 is provided in the connecting portion 15, so that the two desiccant chambers 111 can be connected to each other, which can solve the problem that it is difficult to punch holes at the bottom of the two desiccant chambers 111, and is convenient for manufacturing and processing.

[0035] like Figure 1-Figure 2 As shown, a drying device 100 according to an embodiment of the present invention includes: a housing 1.

[0036] The outer shell 1 includes at least two drying cylinders 11, and a desiccant chamber 111 is formed in each drying cylinder 11, that is, there may be two or three desiccant chambers 111. Specifically, the drying device 100 is used to dry gas. For example, the outer shell 1 includes two drying cylinders 11, and the two drying cylinders 11 are respectively formed with desiccant chambers 111. The drying cylinders 11 are constructed as cylindrical bodies, and the desiccant chambers 111 are constructed as cylindrical chambers. Desiccant is contained in the two desiccant chambers 111, and the gas in the two desiccant chambers 111 is dried and dehumidified respectively.

[0037] Among them, two adjacent drying cylinders 11 are spaced apart and distributed to form a separation space 12 between the two drying cylinders 11. The outer shell 1 also includes a connecting portion 15 connected between one ends of the two adjacent drying cylinders 11. A connecting hole 21 is formed in the connecting portion 15. The desiccant chambers 111 of the two adjacent drying cylinders 11 are connected through the connecting hole 21.

[0038] Specifically, the connecting portion 15 can be connected to the outside of the shell 1 or embedded in the inside of the shell 1. In this embodiment, at least part of the connecting portion 15 is connected to the outside of the shell 1, and the two adjacent drying cylinders 11 are spaced apart, that is, the desiccant chambers 111 are spaced apart and distributed, and the two drying cylinders 11 are spaced apart to form a separation space 12, and the separation space 12 extends along the axial direction of the drying cylinder 11. The two adjacent desiccant chambers 111 are connected through the connecting portion 15. For example, the connecting portion 15 is located at the bottom of the two adjacent drying cylinders 11, and part of the structure of the connecting portion 15 is located in the separation space 12, and both ends of the connecting portion 15 They are respectively connected to two adjacent drying cylinders 11, so that the bottom connection of the two adjacent drying cylinders 11 can be achieved, and a connecting hole 21 is formed in the connecting portion 15, the connecting hole 21 extends along the two adjacent desiccant chambers 111, and the axial ends of the connecting hole 21 are respectively connected to the two adjacent desiccant chambers 111, so that the two desiccant chambers 111 are connected at their bottoms through the connecting hole 21 of the connecting portion 15, wherein the connecting portion 15 can be constructed as a hollow structure, and in actual manufacturing, the connecting portion 15 and the two adjacent drying cylinders 11 can be integrally formed, so that the connection between the two adjacent desiccant chambers 11 is simpler.

[0039] When two drying cylinders 11 are provided in the housing 1, gas is passed into the desiccant chamber 111 of one of the drying cylinders 11, and water may be mixed in the gas. After the desiccant in the desiccant chamber 111 absorbs the water, it enters the desiccant chamber 111 of the other drying cylinder 11 from the connecting hole 21 of the connecting portion 15, and is discharged from the desiccant chamber 111 after drying the gas again, thereby achieving gas drying. Thus, a gas drying flow path can be formed through the connecting hole 21, and the gas in one desiccant chamber 111 is sent from its bottom into the adjacent desiccant chamber 111, which can lengthen the gas flow path and improve the gas drying effect.

[0040] Furthermore, the housing 1 includes a plurality of drying cylinders 11, and a connecting portion 15 is provided between each adjacent drying cylinder 11, which can ensure that at least two desiccant chambers 111 are in a connected state, ensuring that the gas has a flow path formed by at least two desiccant chambers 111, thereby improving the drying effect of the gas.

[0041] Thus, the connecting portion 15 is connected between two adjacent separated drying cylinders 11, and the connecting hole 21 inside the connecting portion 15 can realize the connection between the two adjacent desiccant chambers 111. The manufacturing method of setting the connecting portion 15 is simple and convenient. The bottom space of the two adjacent desiccant chambers 111 is small, which makes it difficult to process a through hole. The connection portion 15 is set to solve the problem that it is difficult to drill a through hole at the bottom of the outer shell 1, thereby improving the production and processing efficiency and meeting the production requirements.

[0042] According to the drying device 100 of the embodiment of the utility model, by setting two adjacent drying cylinders 11 to be spaced apart and connecting one end of the two with a connecting portion having a connecting hole 21, the connection of the desiccant chambers 111 of the two drying cylinders 11 can be achieved. It has a simple structure and is easy to process and manufacture. It can solve the problem that it is difficult to punch holes at the bottom of two closely connected drying cylinders 11, and can form a longer gas flow path, thereby improving the utilization rate of the desiccant and enhancing the drying effect of the gas.

[0043] In some embodiments, the other ends of two adjacent drying cylinders 11 are connected by a connecting block 13, specifically, as Figure 1 As shown, one end of the separation space 12 is connected to a connecting portion 15, through which one ends of two adjacent drying cylinders 11 can be connected, and the other end of the separation space 12 is connected to a connecting block 13, through which the other ends of the two adjacent drying cylinders 11 can be connected, and the connection method can be one-piece molding or welding, thereby, the connection and fixation of the two ends of the two adjacent drying cylinders 11 can be achieved through the connecting portion 15 and the connecting block 13, and the connection is firm and reliable, which can make the gas drying path more stable.

[0044] The connection block 13 is also used to connect and fix the drying device 100 to other structures. A plurality of connection holes may be provided on the connection block 13, and the drying device 100 may be detachably connected to other structures through the plurality of connection holes to form a complete gas drying circuit.

[0045] In some embodiments, there are multiple connecting blocks 13 between two adjacent drying cylinders 11 , and a separation gap 14 is formed between two adjacent connecting blocks 13 , and the separation gap 14 is communicated with the separation space 12 .

[0046] Specifically, Figure 1 As shown, the connecting block 13 is located at the air inlet side of two adjacent drying cylinders 11, and there are multiple connecting blocks 13, which are respectively connected to two adjacent drying cylinders 11, so that multiple connections can be achieved between two adjacent drying cylinders 11, thereby ensuring that the two drying cylinders 11 are reliably connected, and that the drying equipment 100 is reliably connected to other structures, thereby ensuring that the air inlet and outlet of the drying equipment 100 are more stable.

[0047] A separation gap 14 is formed by spacing two adjacent connecting blocks 13, which is connected to the separation space 13 and is located at one end of the separation space 13 away from the connecting portion 15, wherein the connecting blocks 13 can be provided in two, and the two connecting blocks 13 are spaced apart and distributed, and are respectively located in the peripheral area of ​​two adjacent drying cylinders 11 close to each other.

[0048] Among them, the connecting block 13 can also be set as one, and one connecting block 13 is distributed along the shape of two adjacent drying cylinders 11, that is, the shape of the connecting block 13 is matched with the shape of two adjacent drying cylinders 11, and its shape is irregular, and the setting method is more flexible.

[0049] In some embodiments, a filter assembly 3 is provided in the desiccant chamber 111 at one end away from the connecting hole 21. Specifically, the filter assembly 3 is used to filter the gas in the desiccant chamber 111. The filter assembly 3 is provided in the desiccant chamber 111 and is located at the end away from the connecting hole 21, that is, the filter assembly 3 can be located at the gas inlet end of the desiccant chamber 111. In this way, when the gas enters the desiccant chamber 111, the filter assembly 3 can filter out fine dust, particles, etc. contained in the gas, and then the gas is dried through the adsorption effect of the desiccant. The dried gas flows from the connecting hole 21 into another desiccant chamber 111. Therefore, by setting the filter assembly 3, the cleanliness of the gas can be ensured, and impurities such as large particles contained in the gas can be prevented from entering the connecting hole 21 and causing blockage.

[0050] In some embodiments, the filter assembly 3 includes a filter element 31 and a fixing element 32 . The fixing element 32 is fixedly installed in the desiccant chamber 111 , and the filter element 31 is installed on the fixing element 32 .

[0051] Specifically, the filter element 31 is used to filter the gas, and the fixing element 32 is connected to the desiccant chamber 111, so as to realize the connection between the filter assembly 3 and the desiccant chamber 111, and the desiccant can be sealed in the desiccant chamber 111. The filter element 31 is connected to the fixing element 32, and the filter element 31 is located on the side of the fixing element 32 close to the connecting hole 21. The desiccant chamber 111 can be a circular cavity. The shapes of the filter element 31 and the fixing element 32 match the desiccant chamber 111. The filter element 31 fits the inner circumferential wall of the desiccant chamber 111, so that all the gas can pass through the filter element 31, and the filter element 31 can be made of filter cotton. In this way, the gas enters the filter cotton from one side of the fixing element 32, and the dust and impurities mixed in the gas are adsorbed by the filter cotton, and the clean gas flows out, so as to realize the filtration of the gas, and the filtration effect is good, so as to ensure the cleanliness of the dry gas.

[0052] In some embodiments, the fixing member 32 includes a fixing plate portion 321 and a mounting ring portion 322, wherein the mounting ring portion 322 is connected to one side of the fixing plate portion 321 and extends along the axial direction of the desiccant chamber 111. Specifically, as shown in FIG. Figure 2As shown, the fixed plate portion 321 and the mounting ring portion 322 are both constructed as a circle or other arc-shaped structure, and the outer diameter of the mounting ring portion 322 is the same as the outer diameter of the fixed plate portion 321. The mounting ring portion 322 is located in the outer peripheral area of ​​the fixed plate portion 321 and is distributed around the fixed plate portion 321. The radial thickness of the mounting ring portion 322 is relatively thin. The mounting ring portion 322 extends along the axial direction of the desiccant chamber 111 toward a side away from the fixed plate portion 321. The axial extension length thereof may be the same as the axial thickness of the fixed plate portion 321, or may be different, such as Figure 1 As shown, the axial extension length thereof is greater than the axial thickness of the fixing plate portion 321 , wherein, in actual design, the mounting ring portion 322 can be an integral structure with the fixing plate portion 321 and can be processed and formed at one time.

[0053] The mounting ring portion 322 is used for mounting and cooperating with the inner wall of the desiccant chamber 111 , the fixing plate portion 321 is formed with a filter hole 3211 , and the filter element 31 is connected to the fixing plate portion 321 .

[0054] Specifically, the outer periphery of the mounting ring 322 cooperates with the inner wall of the desiccant chamber 111 , and the two can be tightly matched, so that the mounting ring 322 and the desiccant chamber 111 are tightly matched in a circumferential direction, thereby improving the reliability of the installation of the fixing member 32 .

[0055] The fixed plate portion 321 is provided with a filter hole 3211 for the flow of gas. Figure 2 As shown, the filter hole 3211 can be constructed as a circular hole, and there are multiple filter holes 3211. The multiple filter holes 3211 are evenly spaced and distributed along the circumference of the fixed plate portion 321, and multiple groups are formed along the radial direction of the fixed plate portion 321. This arrangement can increase the flow area and flow rate of the gas, and the filter element 31 is located on the side of the fixed plate portion 321 away from the mounting ring portion 322, and the filter element 31 is detachably connected to the fixed plate portion 321, which is convenient for the maintenance and replacement of the filter element 31. In this way, after the gas passes through the fixed plate portion 321, it can evenly enter the filter element 31 for filtration, thereby improving the filtering effect of the gas and preventing dust, impurities, etc. in the gas from clogging other structures such as the connecting hole 21. Among them, the shape of the filter hole 321 can also be an elliptical hole, a square hole, etc.

[0056] In some embodiments, the mounting ring portion 322 has an interference fit with the inner wall of the desiccant chamber 111, so that the mounting ring portion 322 and the desiccant chamber 111 can be reliably installed. Specifically, the outer peripheral walls of the fixed plate portion 321 and the mounting ring portion 322 may be provided with guide surfaces, and the guide surfaces are constructed as inclined surfaces, and are radially inclined outward from one side of the fixed plate portion 321 to the side of the mounting ring portion 322. In this way, during installation, the fixed plate portion 321 is extended into the desiccant chamber 111 along the guide surface, and the outer periphery of the mounting ring portion 322 has an interference fit with the inner wall of the desiccant chamber 111, so as to achieve the installation of the filter assembly 3. The interference fit can reliably fix the fixed plate portion 321 in the desiccant chamber 111, which can prevent the filter assembly 3 from falling out, and can prevent the filter element 31 from tilting, resulting in the desiccant falling out and causing the drying device 100 to fail. Therefore, the sealing effect of the desiccant is better.

[0057] Among them, the axial extension length of the mounting ring portion 322 is relatively long, that is, the interference fit length between the mounting ring portion 322 and the inner wall of the desiccant chamber 111 is relatively long, which can ensure that the mounting ring portion 322 and the desiccant chamber 111 are reliably installed, and the axial extension length of the mounting ring portion 322 can be at least 4 mm, which can effectively prevent the filter assembly 3 from tipping over and causing the desiccant to fall out.

[0058] And / or, the mounting ring portion 322 is connected to a side of the fixing plate portion 321 away from the connecting portion 15 , a side of the fixing plate portion 321 close to the connecting portion 15 is provided with a protruding and extending mounting column 3212 , and the filter element 31 is sleeved on the mounting column 3212 .

[0059] Specifically, Figure 1 As shown, the mounting ring 322 and the filter element 31 are respectively located on both sides of the fixed plate 321. In the axial direction of the desiccant chamber 111, the mounting ring 322 is connected to the side of the fixed plate 321 away from the connecting portion 15. The filter element 31 is located on the side of the fixed plate 321 close to the connecting portion 15. The fixed plate 321 is formed with a mounting column 3212 on the side close to the connecting portion 15. The mounting column 3212 is located at the center of the fixed plate 321 and is disposed along the fixed plate 321. It protrudes and extends axially toward one side of the connecting hole 21, and the extended length is greater than or equal to the thickness of the filter element 31. The filter element 31 is provided with an inner hole, and the filter element 31 is sleeved on the outside of the mounting column 3212 through the inner hole, and the two are tightly matched to ensure that the filter element 31 is reliably installed. During installation, one side of the fixing plate portion 321 is extended into the desiccant chamber 111, and the mounting ring portion 322 is pressed against the inner wall of the desiccant chamber 111, and the mounting ring portion 322 is a thin-walled structure, which is convenient for the installation of the filter assembly 3.

[0060] In some embodiments, the mounting ring portion 322 is formed with a deformation notch 3221 for deformation of the mounting ring portion 322 during installation. Specifically, the deformation notch 3221 can be constructed as a slot structure, such as a strip hole. The deformation notch 3221 extends along the axial direction of the mounting ring portion 322 and penetrates the mounting ring portion 322 radially, and is open on the side of the mounting ring portion 322 away from the fixed plate portion 321, thereby facilitating the deformation of the mounting ring portion 322 under stress.

[0061] Among them, Figure 2 As shown, the deformation notch 3221 can be set to two, and the two deformation notches 3221 are relatively distributed. In this way, during installation, the mounting ring 322 will be subjected to the pressure of the desiccant chamber 111, and the mounting ring 322 is more likely to deform at the two deformation notches 3221, which facilitates the installation of the mounting ring 322, and the mounting ring 322 and the inner wall of the desiccant chamber 111 are reliably pressed and matched, ensuring that the filter assembly 3 is reliably installed, and the installation is simpler and faster. Among them, the number of deformation notches 3221 is not limited to that described in this embodiment, and can be set according to actual needs, as long as it can meet the deformation of the mounting ring 322 and its own strength.

[0062] And / or, the mounting ring 322 is made of a flexible material, which may be rubber or the like. The flexible material itself has a certain elasticity. During the installation process, the mounting ring 322 is pressed by the inner wall of the desiccant chamber 111, and the mounting ring 322 is compressed to reduce its radial dimension, and has an interference fit with the desiccant chamber 111. Since the interference fit length between the mounting ring 322 and the inner wall of the desiccant chamber 111 is relatively long, the flexible material is easier to deform, which facilitates the interference fit between the mounting ring 322 and the desiccant chamber 111, and can avoid movement between the mounting ring 322 and the desiccant chamber 111. The mounting ring 322 is easy to assemble and has higher reliability.

[0063] In some embodiments, a filter net bag 4 is provided in the desiccant chamber 111 at one end close to the connection portion 15. The filter net bag 4 is open toward the desiccant chamber 111 and is concave toward the end where the connection portion 15 is located. The filter net bag 4 has a mesh 41, and the aperture of the mesh 41 is smaller than the outer diameter of the desiccant.

[0064] Specifically, the filter net bag 4 is used to isolate the desiccant. The filter net bag 4 is arranged in the desiccant cavity 111 and is located at one end close to the connection portion 15. The shape of the filter net bag 4 matches the desiccant cavity 111. The filter net bag 4 can be constructed as a circular or arc-shaped structure. An open mouth is provided at one end of the filter net bag 4, and the open mouth is open to the desiccant cavity 111. A part of the filter net bag 4 is in contact with the end of the connection portion 15, and is concave at one end close to the connection portion 15, and the concave side of the filter net bag 4 is in contact with the desiccant cavity 111. The inner bottom wall of the agent cavity 111 is connected, so that the desiccant can be blocked on the concave side of the filter net bag 4. The filter net bag 4 is provided with a mesh 41 for the circulation of gas, wherein the mesh 41 can be a circular hole or other irregularly shaped holes, the aperture of the mesh 41 is relatively small, the aperture of the connecting hole 21 is larger than the aperture of the mesh 41, and the aperture of the mesh 41 is smaller than the outer diameter of the desiccant, so that the desiccant can be prevented from entering the connecting hole 21 from the filter net bag 4, causing the connecting hole 21 in the connecting part 15 to be blocked, thereby reducing the gas flow.

[0065] Among them, there can be at least two filter net bags 4, and at least two filter net bags 4 are respectively located at the two ends of the connecting hole 21 inside the connecting part 15, which can isolate the desiccant in the two desiccant chambers 111 respectively, keep the two ends of the connecting hole 21 unobstructed, increase the flow rate of the airflow, and improve the drying efficiency of the gas.

[0066] In some embodiments, the extension direction of at least two desiccant chambers 111 is the same, and the extension direction of the communication hole 21 intersects with the extension direction of the desiccant chamber 111 .

[0067] That is to say, at least two desiccant chambers 111 in the outer shell 1 have the same extension direction, and there may be more than two desiccant chambers 111 in the outer shell 1 with the same extension direction. Specifically, the cavity structures of the two desiccant chambers 111 may be the same and extend in the same direction. The extension direction of the connecting hole 21 is different from the extension direction of the desiccant chamber 111, and the extension directions of the two intersect. The extension directions of the two may be perpendicular to each other, or the extension directions of the two may be non-perpendicular, as long as the connecting hole 21 can be connected to the two desiccant chambers 111.

[0068] In some embodiments, the drying device 100 further includes an insert 2 , which is installed in the connecting portion 15 , and a communicating hole 21 is defined in the insert 2 .

[0069] Specifically, the insert 2 can be embedded in the connecting part 15, and the two can be manufactured as one. For example, a mounting hole is formed in the connecting part 15, and the insert 2 is embedded in the connecting part 15 through the mounting hole to realize the manufacturing of the two. In addition, such a setting can ensure the connection strength between the insert 2 and the connecting part 15, and prevent the insert 2 from loosening and affecting the flow of gas. Among them, a connecting hole 21 is provided in the insert 2. After the insert 2 is installed in the connecting part 15, the flow of gas at both ends of the connecting part 15 can be realized. The shape of the insert 2 can be a circular ring, a square frame, or other shapes, and the axial extension length of the insert 2 can be less than or equal to the extension length of the connecting part 15, that is, the connecting hole 21 can be a circular hole, a square hole, etc., and its setting method is flexible and diverse. In addition, the setting of the insert 2 can make the connection between two adjacent drying cylinders 11 simpler and more convenient.

[0070] In some embodiments, there are two drying cylinders 11 and both extend vertically, the insert 2 is located at the lower ends of the two drying cylinders 11, the lower ends of the two desiccant chambers 111 are connected to the connecting hole 21, and the upper end of the drying cylinder 11 is formed with an air flow port 112 connected to the desiccant chamber 111.

[0071] Specifically, Figure 2 As shown, the two drying cylinders 11 extend vertically, the extension direction of the two desiccant chambers 111 is also vertical, the bottom of the drying cylinder 11 is a closed end, the insert 2 is located at the lower end of the two desiccant chambers 111, and the insert 2 is installed in the horizontal direction, and the connecting hole 21 extends in the horizontal direction, and its extension direction is perpendicular to the extension direction of the two desiccant chambers 111, so that the lower ends of the two desiccant chambers 111 are connected through the connecting hole 21. In this way, a U-shaped gas flow path can be formed in the outer shell 1, so that the gas flow path is enlarged, which can increase the drying and filtering effects of the gas.

[0072] The upper end of the drying cylinder 11 is a gas inlet end, and an air flow port 112 is formed thereon. The air flow port 112 is connected to the desiccant chamber 111, and the desiccant chamber 111 is connected to a gas pipeline or an airway through the air flow port 112. A filter assembly 3 is connected to the upper end region of the desiccant chamber 111, so that the gas is passed from the air flow port 112 into the desiccant chamber 111, filtered by the filter assembly 3, and then dried by the desiccant, and the dry and clean gas enters another desiccant chamber 111 through the connecting hole 21, and can continue to be dried and filtered, thereby improving the drying and filtering effects of the gas, and reducing the corrosion and clogging of various components caused by moisture and particles in the gas for a long time.

[0073] The utility model also provides a compressor.

[0074] According to the compressor of the embodiment of the utility model, a drying device 100 according to any one of the above-mentioned embodiments is provided. By arranging two adjacent drying cylinders 11 to be spaced apart and connecting one end of the two with a connecting portion having a connecting hole 21, the desiccant chambers 111 of the two drying cylinders 11 can be connected. The structure is simple and the processing and manufacturing are convenient. The problem that it is difficult to punch holes at the bottom of two closely connected drying cylinders 11 can be solved, and a longer gas flow path can be formed, thereby improving the utilization rate of the desiccant, enhancing the drying effect of the gas, and ensuring that the gas in the compressor is in a dry state, reducing the corrosion of various components by moisture in the gas, thereby improving the performance of the compressor.

[0075] The utility model also provides an air suspension.

[0076] According to the air suspension of the embodiment of the utility model, the compressor of the above embodiment is provided. By providing the above drying device 100, the dryness and cleanliness of the gas in the compressor can be ensured, the compression performance of the compressor gas can be improved, and the dryness and cleanliness of the gas provided to the air suspension can be ensured, so as to ensure the stability of the air suspension during dynamic adjustment, thereby ensuring the smooth operation of the vehicle.
