[0033] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0034] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0035] As mentioned earlier, adsorption drying equipment typically uses an adsorbent to adsorb moisture from gases (such as compressed air) to achieve the purpose of drying the gas. Adsorption drying equipment usually includes a drying tower. To extend the flow path of the gas being dried within the drying tower, the inlet and outlet are usually located at opposite ends of the tower (e.g., the top and bottom) to improve adsorption efficiency. In this case, because the inlet and outlet pipes need to extend to both ends of the drying tower to connect with the inlet and outlet, connecting gas pipes are usually provided at both the top and bottom of the drying tower. This results in a relatively large vertical dimension for the adsorption drying equipment, which is inconvenient for storage and transportation. Furthermore, most existing adsorption drying equipment is fixed and cannot be easily moved. Therefore, how to reduce the size of adsorption drying equipment (especially its height) and how to make it easier to store and transport are issues of concern.

[0036] To address, or at least partially address, the aforementioned problems or other potential problems existing in conventional technologies, embodiments of this disclosure provide an adsorption drying device. In this improved solution, the adsorption drying device includes a drying assembly comprising at least one drying tower and one or more filters. Each drying tower includes at least a tower body and an adsorbent. The tower body has a drying chamber, an air inlet communicating with the drying chamber, and an exhaust port communicating with the drying chamber. The adsorbent is deployed in the drying chamber. At least one of the air inlet and exhaust port is disposed on the side wall of the tower body. The air inlet communicates with the space below the adsorbent in the drying chamber, and the exhaust port communicates with the space above the adsorbent in the drying chamber. The one or more filters are deployed to the side of at least one drying tower. The one or more filters include at least one pre-filter and / or at least one post-filter. The at least one pre-filter communicates with the air inlet via an air inlet pipe, and the at least one post-filter communicates with the exhaust port via an exhaust pipe.

[0037] In embodiments of this disclosure, the air inlet or outlet is located on the side wall of the drying tower. An air inlet pipe can be connected to the air inlet of the drying tower from the side, or an exhaust pipe can be connected to the exhaust outlet of the drying tower from the side. This approach helps to reduce the length of the adsorption drying equipment within the drying tower, improves the compactness of the adsorption drying equipment, and reduces the space occupied by the adsorption drying equipment, thus facilitating its storage and transportation.

[0038] Figure 1 A perspective view of an adsorption drying apparatus according to some embodiments of the present disclosure is shown. Figure 1 In order to show the internal structure of the drying tower, a drying tower (sometimes referred to as the first drying tower in this paper) is converted to a perspective view. Figure 2 A side view of an adsorption drying apparatus according to some embodiments of the present disclosure is shown. Figure 3 A top view of an adsorption drying apparatus according to some embodiments of the present disclosure is shown. Figure 4 It shows Figure 1 A magnified view of part A in the middle.

[0039] See Figures 1 to 4 As shown, the adsorption drying apparatus of an embodiment of this disclosure includes a drying assembly 100. The drying assembly 100 includes at least one drying tower 110 and one or more filters 130. These components will be described in detail below.

[0040] The drying tower 110 may include a tower body 111 and a regenerable adsorbent (not shown). The tower body 111 has a drying chamber 112, an air inlet 113 communicating with the drying chamber 112, and an exhaust port 114 communicating with the drying chamber 112. The adsorbent is disposed in the drying chamber 112. In some examples, the drying chamber 112 may be provided with a structure or component (e.g., a cylinder or drum, etc.) for containing the adsorbent, and the adsorbent may fill the structure or component.

[0041] At least one of the air inlet 113 and the exhaust outlet 114 is disposed on the side wall of the tower body 111. The side wall can be understood as a side wall structure located between the two ends of the tower body 111. As an example, the tower body 111 may include a top wall, a bottom wall, and a cylindrical or approximately cylindrical structure located between the top and bottom walls; the wall of this cylindrical structure can be understood as the side wall. At least one of the air inlet 113 and the exhaust outlet 114 is formed on the wall of this cylindrical structure. For example, the exhaust outlet 114 may be formed on the wall of the cylindrical structure and near the vertical center of the cylindrical structure.

[0042] The air inlet 113 communicates with the space below the adsorbent in the drying chamber 112, and the exhaust port 114 communicates with the space above the adsorbent in the drying chamber 112. The space below the adsorbent in the drying chamber 112 can be the space defined between the adsorbent and the bottom wall of the tower body 111, and the space above the adsorbent in the drying chamber 112 can be the space defined between the adsorbent and the top wall of the adsorption tower. For ease of description, the space below the adsorbent in the drying chamber 112 will be referred to as the "bottom space," and the space above the adsorbent in the drying chamber 112 will be referred to as the "top space." As an example, the adsorbent can be deployed in the middle of the drying chamber 112 vertically. The bottom and top walls of the tower body 111 can be hemispherical, with the bottom space defined between the adsorbent and the hemispherical bottom wall, and the top space defined between the adsorbent and the hemispherical top wall.

[0043] The connection between the air inlet 113 and the bottom space can be understood as a direct or indirect connection between the air inlet 113 and the bottom space, allowing the air inlet 113 to deliver the gas to be dried to the bottom space. The gas can then flow through the adsorbent, which adsorbs moisture from the gas, thus achieving the purpose of drying the gas. In some examples, combined with... Figure 2As shown, the air inlet 113 can be deployed at the bottom of the tower body 111. In this case, the air inlet 113 can be directly connected to the bottom space. Alternatively, the air inlet 113 can be located on the side wall of the tower body 111. In this case, the air inlet 113 can be connected to the bottom space via a pipe deployed in the drying chamber 112. As an example, the inlet end of the pipe can be connected to the air inlet 113, and the outlet end of the pipe can be connected to the bottom space. Of course, the above-described connection method between the air inlet 113 and the bottom space is merely exemplary.

[0044] The connection between the exhaust port 114 and the top space can be understood as a direct or indirect connection between the exhaust port 114 and the bottom space, so that the dried gas in the top space can be transported out of the drying tower 110 via the exhaust port 114, for example, to the post-filter 132. In some examples, combined with Figure 3 and Figure 4 As shown, the exhaust port 114 can be located on the side wall of the tower body 111. A guide pipe 115 can be provided inside the drying chamber 112, with the inlet end of the guide pipe 115 connected to the top space and the outlet end connected to the exhaust port 114. In this way, the dried gas can be guided through the guide pipe 115 to the exhaust port 114 on the side of the tower body 111 for discharge. As an example, continuing with... Figure 3 and Figure 4 As shown, the side wall of the tower body 111 is provided with an annular connecting portion 116 surrounding the exhaust port 114, and the exhaust end of the air guide pipe 115 can be connected to the portion of the annular connecting portion 116 located in the drying chamber 112. For example, the exhaust end of the air guide pipe 115 can be connected to the annular connecting portion 116 via, for example, a flange.

[0045] The one or more filters 130 may be deployed on the side of at least one drying tower 110. In some embodiments, the one or more filters 130 may include at least one pre-filter 131. The at least one pre-filter 131 may be connected to the air inlet 113 of the drying tower 110 via an air inlet pipe. The pre-filter 131 can filter out at least some impurities (e.g., oil mist, water vapor, etc.) in the gas to be dried, thereby reducing the impact of impurities on the drying tower 110 and extending the service life of the drying tower 110 (e.g., the adsorbent).

[0046] In some examples, combined Figures 1 to 3As shown, the at least one drying tower 110 may include a first drying tower 117 and a second drying tower 118. The air inlet 113 of the first drying tower 117 is located at the bottom end of the first drying tower 117, and the air inlet 113 of the second drying tower 118 is located at the bottom end of the second drying tower 118. The air outlet of the pre-filter 131 may be connected to the air inlet of the first air inlet pipe 141, and the air outlet of the first air inlet pipe 141 may be connected to the air inlet of the second air inlet pipe 142 and the air inlet of the third air inlet pipe 143, respectively. The air outlet of the second air inlet pipe 142 may be connected to the air inlet 113 of the first drying tower 117, and the air outlet of the third air inlet pipe 143 may be connected to the air inlet 113 of the second drying tower 118.

[0047] Alternatively or additionally, the one or more filters 130 may also include at least one post-filter 132. The at least one post-filter 132 is connected to the exhaust port 114 of the drying tower 110 via an exhaust pipe. The post-filter 132 can filter out at least some impurities (such as dust, etc.) in the dried gas, thereby improving the cleanliness of the exhaust gas.

[0048] In some examples, combined Figure 1 , Figure 3 and Figure 4 As shown, the exhaust port 114 of the first drying tower 117 can be located on the side wall of the first drying tower 117, and the exhaust port 114 of the second drying tower 118 can be located on the side wall of the second drying tower 118. The exhaust port 114 of the first drying tower 117 can be connected to the inlet end of the first exhaust pipe 151, for example, the inlet end of the first exhaust pipe 151 can be connected to the annular connection part 116 via a flange. The exhaust port 114 of the second drying tower 118 can be connected to the inlet end of the second exhaust pipe 152. The outlet ends of both the first exhaust pipe 151 and the second exhaust pipe 152 can be connected to the inlet end of the third exhaust pipe 153, and the outlet end of the third exhaust pipe 153 can be connected to the inlet end of the post-filter 132. The outlet end of the post-filter 132 can be connected to the inlet end of the fourth exhaust pipe 154.

[0049] In some embodiments, the at least one drying tower 110 may be arranged sequentially along a first direction, and the one or more filters 130 are all deployed on the same side of the at least one drying tower 110 in a second direction perpendicular to the first direction, and the one or more filters 130 are arranged sequentially along the first direction. Deploying the filters 130 on the same side of the drying tower 110 facilitates pipe layout, and having multiple filters 130 on the same side makes disassembly and assembly easier, improving the compactness of the drying equipment while facilitating its later maintenance. As an example, combined with... Figures 1 to 3As shown, the first drying tower 117 and the second drying tower 118 can be arranged sequentially along the X-axis direction. The pre-filter 131 and the post-filter 132 are both deployed on the same side of the first drying tower 117 and the second drying tower 118 in the Y-axis direction, and the pre-filter 131 and the post-filter 132 are arranged sequentially along the X-axis direction.

[0050] In some embodiments, at least a portion of the air intake duct and / or at least a portion of the exhaust duct may be deployed on the side of the at least one drying tower 110. This reduces the vertical dimensions (also referred to as the height) of the adsorption drying equipment.

[0051] In some examples, combined Figures 1 to 3 As shown, if the air inlet 113 of the first drying tower 117 is located at the bottom of the first drying tower 117, and the air inlet 113 of the second drying tower 118 is also located at the bottom of the second drying tower 118, then the first air inlet pipe 141 can be deployed on one side of the first drying tower 117 and the second drying tower 118 in the Y-axis direction, and the second air inlet pipe 142 and the third air inlet pipe 143 can extend to the bottom of the first drying tower 117 and the second drying tower 118, respectively.

[0052] Alternatively, if the air inlet 113 of the first drying tower 117 is located to the side of the first drying tower 117, and the air inlet 113 of the second drying tower 118 is also located to the side of the second drying tower 118, then the first air inlet pipe 141, the second air inlet pipe 142 and the third air inlet pipe 143 can all be deployed to the side of the first drying tower 117 and the second drying tower 118.

[0053] In some examples, continue to combine Figures 1 to 3 As shown, if the exhaust port 114 of the first drying tower 117 is located on the side of the first drying tower 117, and the exhaust port 114 of the second drying tower 118 is also located on the side of the second drying tower 118, then the first exhaust pipe 151, the second exhaust pipe 152 and the third exhaust pipe 154 can all be located on the side of the first drying tower 117 and the second drying tower 118.

[0054] In some embodiments, the filter 130 (e.g., pre-filter 131 or post-filter 132) may include a housing, end caps, and a filter element. The housing may be arranged vertically, and an opening is provided at the bottom end of the housing. The filter element is disposed inside the housing, and the end caps are detachably connected to the bottom end of the housing to seal the opening of the housing. The vertical distance between the bottom end of the housing and the bottom of the adsorption dryer is greater than the vertical length of the filter element. In this way, sufficient space is provided for filter element replacement. If filter element replacement is required, the filter element can be easily removed by removing the end caps, which improves the convenience of filter 130 maintenance.

[0055] In some embodiments, continue to combine Figures 1 to 3 As shown, the drying assembly 100 may further include a gas-liquid separator 120, the outlet of which is connected to at least one pre-filter 131. Thus, the gas-liquid separator 120 can filter out at least a portion of the liquid water and oil mist from the gas to be dried, improving the cleanliness of the gas and reducing the impact of liquid water and oil mist on the pre-filter 131 and the drying tower 110. Examples of the gas-liquid separator 120 may include, but are not limited to, centrifugal gas-liquid separators, cyclone gas-liquid separators, or gravity gas-liquid separators, etc. As an example, in conjunction with... Figures 1 to 3 As shown, the air inlet of the air-water separator 120 can be connected to the fourth air inlet pipe 144, and the air outlet of the air-water separator 120 can be connected to the pre-filter 131 through the fifth air inlet pipe 145.

[0056] In some embodiments, combined with Figure 2 As shown, the drying assembly 100 may further include a first regeneration conduit 161. The inlet end of the first regeneration conduit 161 can be connected to a first exhaust conduit 151, and the exhaust end of the first regeneration conduit 161 can be connected to the exhaust port 114 of the first drying tower 117. Dried gas can be introduced into the first drying tower 117 through the first regeneration conduit 161 to regenerate the adsorbent in the first drying tower 117. In some examples, a pressure gauge 163 and a valve 164 may be deployed on the first regeneration conduit 161. The pressure gauge 163 clearly displays the pressure of the gas in the first regeneration conduit 161. The valve 164 can regulate the flow rate of the gas in the first regeneration conduit 161. Examples of valves 164 include, but are not limited to, manual or electric valves.

[0057] Alternatively or additionally, the drying assembly 100 may also include a second regeneration conduit 162. The inlet end of the second regeneration conduit 162 may be connected to a second exhaust conduit 152, and the exhaust end of the second regeneration conduit 162 may be connected to the exhaust port of the second drying tower 118. The dried gas can be introduced into the second drying tower 118 through the second regeneration conduit 162 to regenerate the adsorbent in the second drying tower 118.

[0058] Figure 5 A perspective view of an adsorption drying apparatus according to other embodiments of this disclosure is shown. See also Figure 5 As shown, in some embodiments, the adsorption drying device may further include a shell structure 200, which has a receiving space 210 in which the drying component 100 is deployed. The shell structure 200 can protect the drying component 100 and improve the convenience of storage and transportation of the drying device.

[0059] The shell structure 200 can be understood as the external protective structure of the adsorption drying equipment, and can be any suitable structure capable of supporting and protecting the drying components 100. As an example, combined with... Figure 5 As shown, the shell structure 200 may include a matching top cover 220 and a base 230, which are connected by a plurality of vertically extending columns 240 to form an "open" shell structure. Of course, the shell structure 200 described above is merely exemplary. The shell structure 200 may also employ any other suitable structure, such as a frame structure, a closed box structure, or a semi-closed box structure, etc. The embodiments of this disclosure do not limit this.

[0060] Figure 6 A perspective view of two stacked adsorption drying devices is shown. In some embodiments, combined with Figure 5 and Figure 6 As shown, the top cover 220 and the base 230 can be configured such that the shell structure 200 of one adsorption dryer is suitable for stacking on top of the shell structure 200 of another adsorption dryer. Thus, multiple adsorption dryers can be stacked sequentially during use, storage, or transportation. Figure 6 As shown, this can reduce the floor space required for adsorption drying equipment, thereby reducing storage and transportation costs.

[0061] In some embodiments, the top surface of the top cover 220 may include a support portion, and the bottom surface of the base 230 may include a supported portion that matches the position and shape of the support portion. When one adsorption drying device is stacked on top of another adsorption drying device, the support portion of the lower adsorption drying device can support the supported portion of the upper adsorption drying device.

[0062] It is understandable that the supporting and supported parts can be implemented in various ways. In some examples, the base 230 may include a first outer frame 231, and the top cover 220 may include a second outer frame 221. The bottom of the first outer frame 231 may have one or more flat supported surfaces, and the top of the second outer frame 221 may have one or more flat supporting surfaces, with each supported surface corresponding to a supporting surface. These one or more supported surfaces can form the supported part, and these one or more supporting surfaces can form the supporting part. When one adsorption drying device is stacked on top of another adsorption drying device, the supporting surface can abut against the corresponding supported surface, and the supporting surface can stably support the corresponding supported surface.

[0063] As an example, combined Figure 5 and Figure 6 As shown, both the first outer frame 231 and the second outer frame 221 can be rectangular or approximately rectangular, and the dimensions of the first outer frame 231 and the second outer frame 221 are the same or substantially the same.

[0064] Of course, the above-described supporting and supported parts are merely exemplary, and other suitable structures can be selected according to actual needs. For example, the top cover 220 may include a flat top surface, through which the supporting part can be formed. The base 230 may include a flat bottom surface, through which the supported part can be formed. Alternatively, the top surface of the top cover 220 may be provided with multiple groove-shaped structures, and the bottom of the base 230 may be provided with multiple legs, each corresponding one-to-one with a groove-shaped structure. These multiple groove-shaped structures can form the supporting part, and the multiple legs can form the supported part. The embodiments disclosed herein do not limit this.

[0065] Figure 7 It shows Figure 5 A magnified view of part B in the middle section. Figure 8 It shows Figure 6 A magnified view of part C in the middle. Figure 8 In order to present the first stop 227, a portion of the first outer frame 231 is converted into a perspective state. In some embodiments, in conjunction with Figures 5 to 8 As shown, the top of the top cover 220 is provided with multiple first stop portions 227, and the bottom of the base 230 is provided with multiple second stop portions 232 corresponding to the multiple first stop portions 227. When one adsorption drying device is stacked on top of another adsorption drying device, the multiple second stop portions 232 of the one adsorption drying device and the multiple first stop portions 227 of the other adsorption drying device mutually stop each other, which can limit the relative displacement of the two adsorption drying devices in the lateral direction. Therefore, the stability of the stacked adsorption drying devices can be improved, preventing the adsorption drying devices from tipping over or falling.

[0066] In some embodiments, the plurality of first stops 227 include a plurality of protrusions disposed on the top of the top cover 220. The first outer frame 231 may be polygonal, and a plurality of second stops 232 are formed at the plurality of corners of the first outer frame 231, the protrusions being adapted to cooperate with the corresponding corners to limit the relative displacement of two stacked adsorption drying devices in the lateral direction.

[0067] As an example, continue to combine Figures 5 to 8As shown, both the first outer frame 231 and the second outer frame 221 can be rectangular, and the length and width dimensions of the first outer frame 231 and the second outer frame 221 are the same or substantially the same. Four protrusions are respectively provided at the four corners of the top cover 220 near the second outer frame 221, forming four first stop portions 227. Four second stop portions 232 are respectively formed at the four corners of the first outer frame 231. When one adsorption drying device is stacked on top of another adsorption drying device, the four protrusions of the lower adsorption drying device extend into the inner sides of the four corner portions of the upper adsorption drying device, thereby restricting the relative displacement of the two adsorption drying devices in the lateral direction. Of course, the aforementioned first stop portions 227 and second stop portions 232 are merely exemplary. In practical applications, the first support portion and the second support portion can also be formed by, for example, mutually matching limiting blocks and groove-like structures. The embodiments of this disclosure do not limit this.

[0068] Figure 9 A schematic diagram of a transfer scenario for an adsorption drying apparatus according to other embodiments of the present disclosure is shown. In some embodiments, combined with Figure 5 and Figure 9 As shown, multiple lifting components 224 can be installed on the top of the top cover 220. If it is necessary to lift the adsorption drying equipment, lifting tools 310 such as lifting rods or slings can be connected to the lifting components, such as... Figure 9 As shown. The adsorption drying equipment can then be lifted and transported using equipment such as cranes or hoists.

[0069] In some examples, combined Figure 5 and Figure 7 As shown, the top of the top cover 220 can be provided with multiple grooves 223, and multiple lifting components 224 can be deployed in the multiple grooves 223 respectively. In this way, the lifting components 224 can be prevented from affecting the stacking of the adsorption drying equipment. As an example, the top cover 220 can be rectangular, and grooves 223 can be provided at the four corners of the top cover 220, and a lifting component 224 can be set in the groove 223 at each corner of the top cover 220. This helps to improve the stability of the adsorption drying equipment during the lifting process.

[0070] In some examples, combined Figure 7As shown, the lifting component 224 includes a plate-like structure 225 vertically disposed within a groove 223, with a through hole 226 formed in the plate-like structure 225. This lifting component 224 is not only simple in structure but also robust and reliable. As an example, the plate surface of the plate-like structure 225 can be laid vertically, one side of the plate-like structure 225 can be close to the apex of the second outer frame 221, and the other side of the plate-like structure 225 can extend towards the middle of the second outer frame 221. This not only facilitates the connection between the lifting rod and other lifting tools 310 and the lifting component 224 but also helps improve the stability of the adsorption drying equipment during lifting.

[0071] In some embodiments, combined with Figure 5 and Figure 9 As shown, the base 230 may be provided with a set of first forklift holes 233 extending along a first direction. Thus, the adsorption drying equipment can be transported using a forklift 320. As an example, in conjunction with... Figure 5 As shown, a pair of tubes extending along the X-axis and having a rectangular cross-section can be installed within the first frame. The two ends of the pair of tubes can respectively penetrate to the outer surface of the first frame in the X-axis direction, forming a pair of first forklift holes 233 through the inner cavities of the pair of tubes.

[0072] Alternate or additional land, continue to be combined Figure 5 and Figure 9 As shown, the base 230 may also be provided with a set of second forklift holes 234 extending in a second direction perpendicular to the first direction. This facilitates the transport of the adsorption drying equipment by a forklift 320 from different directions. As an example, combined with... Figure 5 As shown, another pair of tubing extending along the Y-axis and having a rectangular cross-section can also be provided within the first frame. The two ends of this other pair of tubing can respectively penetrate to the outer surface of the first frame in the Y-axis direction, forming a pair of second forklift holes 234 through the inner cavity of this other pair of tubing. It should be understood that the aforementioned forklift holes are merely exemplary, and the embodiments disclosed herein are not intended to limit their scope.

[0073] In some embodiments, combined with Figure 5 As shown, the top cover 220 may also include a protective mesh 222 disposed within the second outer frame 221. This prevents debris from falling into the receiving space 210 via the top of the shell structure 200.

[0074] In some embodiments, combined with Figure 5 and Figure 6 As shown, at least one climbing ladder 250 can be provided between the top cover 220 and the base 230. This facilitates climbing to the top of the adsorption dryer for inspection or maintenance, especially when multiple adsorption dryers are stacked, significantly improving the convenience of inspection and maintenance.

[0075] The operation of the adsorption drying equipment will be described below with reference to the accompanying drawings.

[0076] Combination Figures 1 to 3 As shown, the gas to be dried (e.g., compressed air) enters the gas-water separator 120 via the fourth intake pipe 144. The gas-water separator 120 removes at least a portion of the moisture and oil mist from the gas.

[0077] The gas flowing out of the gas-liquid separator 120 enters the pre-filter 131 through the fifth air inlet pipe 145. The pre-filter 131 further filters out at least some impurities in the gas, such as oil mist or water vapor.

[0078] After being filtered, the gas flows out of the pre-filter 131 and then flows vertically downwards through the first inlet pipe 141 into the second inlet pipe 142 or the third inlet pipe 143. It then enters the first drying tower 117 through the second inlet pipe 142, or the second drying tower 118 through the third inlet pipe 143. The adsorbent in the first drying tower 117 or the second drying tower 118 adsorbs moisture from the gas, thus achieving the purpose of drying the gas.

[0079] The dried gas exiting the first drying tower 117 or the second drying tower 118 flows into the third exhaust pipe 153 via the first exhaust pipe 151 or the second exhaust pipe 152, and then enters the post-filter 132 through the third exhaust pipe 153. The post-filter 132 filters out at least some impurities, such as dust, from the dried gas again. Afterwards, the filtered dried gas is delivered to the outside via the fourth exhaust pipe 154.

[0080] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
