[0021] This invention proposes a drying tower, which aims to improve the problems of existing new energy equipment, such as high construction difficulty, poor construction quality, and low construction efficiency.

[0022] In one embodiment of the present invention, the drying tower includes a support ring, a lower cone, a cylindrical body, a tower top structure, and an air distributor. The support ring is used for mounting on an installation plane and includes multiple ring segments spaced apart around an axis extending vertically. Each ring segment is connected to two adjacent ring segments. The lower cone tapers from top to bottom and includes multiple conical plates spaced apart around an axis extending vertically. Each conical plate is located on the inner ring surface of the support ring and protrudes below the support ring. Each conical plate is inclined from top to bottom toward the center of the lower cone and is connected to two adjacent conical plates. The cylindrical body is located on the upper end face of the lower cone and extends vertically. The cylindrical body includes multiple cylindrical plates spaced apart around an axis extending vertically. Each cylindrical plate is connected to two adjacent cylindrical plates. The tower top structure is located on the upper end face of the cylindrical body and includes a tower top frame and multiple top plates. The tower top frame is fixedly connected to the upper end face of the cylindrical body and has a through hole extending vertically through its center. The multiple top plates are spaced apart around an axis extending vertically and all avoid the through hole. The air distributor is located on the tower top frame and at least partially extends into the through hole. In the technical solution of this invention, the installation position of the drying tower is ensured by installing multiple ring segments onto the mounting plane. Then, multiple cone plates are sequentially installed onto the inner ring surface of the support ring, using the support ring as a positioning reference to ensure the installation accuracy of the lower cone. Each cone plate is inclined downwards towards the center of the lower cone and tightly connected to adjacent cone plates to form a stable lower cone. Next, multiple cylindrical plates are fixed to the upper end face of the lower cone to ensure the structural stability of the cylindrical body. Subsequently, the tower top frame is installed onto the upper end face of the cylindrical body, and multiple top plates are sequentially installed onto the upper end face of the tower top frame and fixedly connected to form a complete tower top structure. Finally, the air distributor is installed into the through hole of the tower top structure to complete the overall assembly of the drying tower. This configuration allows the support ring to serve as the installation reference for the lower cone, which in turn serves as the installation reference for the cylinder, which in turn serves as the installation reference for the tower top structure, and which in turn serves as the installation reference for the air distributor. This effectively avoids overall installation deviations caused by cumulative errors and improves the overall installation accuracy of the drying tower. Furthermore, the separate arrangement of multiple ring segments, multiple cone plates, multiple cylinder plates, and multiple top plates further enhances the construction efficiency of the drying tower.

[0023] This invention also proposes a construction method for a drying tower, used to construct the aforementioned drying tower. In the first embodiment of this invention, please refer to... Figure 1 The construction method of the drying tower includes: S10. Install the support ring onto the mounting surface; It is understandable that when installing the support ring, it is necessary to ensure that the flatness of the mounting surface meets the preset requirements in order to provide a stable mounting base and thus ensure the angular accuracy of the support ring.

[0024] S20. Install the lower cone onto the inner ring surface of the support ring; Understandable, When installing the lower cone, the support ring can serve as the installation reference for the lower cone. At the same time, it is necessary to strictly control the tilt angle and connection accuracy of each cone plate to ensure that the overall shape and size of the lower cone meet the design requirements and provide an accurate reference for the installation of subsequent components.

[0025] S30. Install the cylinder onto the upper end face of the lower cone; When installing the cylinder, the lower cone can serve as the installation reference for the cylinder. At the same time, it is also necessary to ensure the verticality of the cylinder after installation to avoid excessive tilting of the cylinder, thereby ensuring the overall structural stability of the drying tower.

[0026] S40. Install the tower top structure onto the upper end face of the cylinder; When installing the tower top structure, the cylinder can serve as the installation reference for the tower top structure. At this time, it is necessary to ensure that the fixed connection between the tower top structure and the upper end face of the cylinder is firm and reliable, and at the same time, the tower top structure covers the through hole of the cylinder.

[0027] In the technical solution of this invention, firstly, the support ring is installed on the mounting plane. This provides a further installation reference for subsequent component installations. Then, the lower cone is installed onto the inner ring surface of the support ring. The support ring forms the installation reference, enabling the lower cone to be positioned and installed, and allowing it to serve as the installation reference for the next component. Next, the cylinder is installed onto the upper end face of the lower cone. At this point, the lower cone forms the installation reference for the cylinder, ensuring accurate cylinder installation. Finally, the tower top structure is installed onto the upper end face of the cylinder. Thus, the cylinder forms the installation reference for the tower top structure, enabling accurate and stable installation of the tower top structure, ultimately forming the drying tower. This setup, with its step-by-step installation and each step using the components installed in the previous step as a reference, effectively avoids overall installation deviations caused by cumulative errors, improving the overall installation accuracy of the drying tower and ensuring construction quality. Furthermore, the sequential installation of the support ring, the lower cone, the cylinder, and the tower top structure allows for more flexible construction of the drying tower, thereby improving construction efficiency.

[0028] In the second embodiment of the present invention, please refer to Figure 2 Step S10, installing the support ring on the mounting plane, includes: S11. Pre-install the plurality of the ring segments onto the mounting plane; It is understandable that, since the installation accuracy of the support ring directly affects the overall installation accuracy of the drying tower, the support ring needs to be pre-installed before it is fixedly installed to ensure its installation accuracy.

[0029] It should be noted that the multiple ring segments can be pre-rotated by using stiffening plates and tie rod bolts.

[0030] S12. Detect the installation data of multiple ring segments; It should also be noted that the installation data includes the levelness of each ring segment and the diameter deviation of the support ring composed of each ring segment.

[0031] S13. When the installation data is not higher than the preset installation data, fix the multiple ring segments to the installation plane and connect the multiple ring segments into one.

[0032] Specifically, the preset levelness is 2mm, and the preset diameter deviation is ±2mm.

[0033] It is understood that when the levelness of each ring segment is ≤2mm and the diameter deviation of the support ring is within ±2mm, it indicates that the installation data is not higher than the preset installation data. At this time, the support ring and the mounting plane are fixedly connected.

[0034] In this embodiment, the support ring and the mounting plane are connected by spot welding.

[0035] In the technical solution of this embodiment, when the support ring is installed on the mounting plane, multiple ring segments are pre-installed and their installation data is checked. Only when the levelness of each ring segment and the diameter deviation of the support ring meet the preset requirements are they fixedly connected. In this way, the installation accuracy of the support ring can be ensured, thereby providing an accurate benchmark for the installation of subsequent components, effectively avoiding the overall installation error caused by the installation deviation of the support ring, and improving the overall installation quality of the drying tower.

[0036] Furthermore, the spot welding connection method can ensure the connection strength between the support ring and the mounting plane, and also facilitates necessary adjustments and corrections during subsequent construction.

[0037] In the third embodiment of the present invention, please refer to Figure 3Step S20, installing the lower cone onto the inner ring surface of the support ring, includes: S21. Hoist one of the cone plates to the inner ring of the support ring and fix it to the inner ring surface of the support ring; Understandably, when hoisting the conical plates, it is necessary to ensure that the inclination angle of the conical plates meets the design requirements to facilitate smooth connection between the conical plates and accurate formation of the overall shape. Simultaneously, the connection strength between the conical plates and the support ring must be guaranteed to prevent displacement or loosening of the conical plates during subsequent installation.

[0038] S22. The other cone plates are sequentially hoisted to the inner ring of the support ring, and at least one adjacent cone plate is fixedly connected to the inner ring surface of the support ring.

[0039] This configuration, by hoisting and fixing each cone plate individually, ensures that the installation position and tilt angle of each cone plate meet the design requirements.

[0040] In this embodiment, during the installation of the lower cone, one of the cone plates is first accurately hoisted and fixed to the inner ring surface of the support ring, providing a reliable positioning reference for the subsequent installation of the cone plates. Then, the remaining cone plates are hoisted one by one, ensuring that each cone plate is not only securely connected to the inner ring surface of the support ring but also tightly connected to at least one adjacent cone plate. This continues until the last cone plate is hoisted, at which point it is simultaneously connected to two adjacent cone plates. This arrangement not only ensures the connection accuracy between the multiple cone plates but also allows the lower cone to form a stable and accurately shaped whole, guaranteeing construction quality. Furthermore, the sequential installation of multiple cone plates further improves the construction efficiency of the drying tower.

[0041] It should be further explained that when installing the lower cone, the straightness of the lower cone needs to meet preset requirements. Specifically, in a further embodiment of the present invention, the actual height of the lower cone in the vertical direction is h1, and the distance between the actual central axis of the lower cone in the vertical direction and the theoretical central axis of the drying tower in the vertical direction is d1, where d1 ≤ h1 / 200mm. This setting, by strictly controlling the straightness of the lower cone, effectively ensures the shape and positional accuracy of the lower cone, thereby guaranteeing the installation accuracy of subsequent components, as well as the installation stability and working performance of the drying tower.

[0042] Furthermore, in another embodiment of the present invention, after step S20, it is necessary to install the bottom cone onto the lower end face of the lower cone. It is understood that the bottom cone is an existing finished part, and its specific installation method will not be described again in the present invention.

[0043] In the fourth embodiment of the present invention, please refer to Figure 4 Step S30, the installation of the cylinder onto the upper end face of the lower cone, includes: S31. The multiple cylindrical plates are hoisted sequentially to the top of the lower cone and abut against the upper end face of the lower cone; It should be noted that in this embodiment, the number of cylindrical plates is equal to the number of conical plates. Therefore, when the cylindrical plates are hoisted above the lower cone, each cylindrical plate corresponds to one conical plate. At this time, the lower cone can provide stable support for multiple cylindrical plates, thereby ensuring the positional accuracy of the cylindrical plates during hoisting and providing temporary fixation for the cylindrical plates, which facilitates subsequent adjustment of the verticality of the cylindrical plates.

[0044] S32. Detect the verticality of each of the aforementioned cylinder plates; It is understood that the verticality of the cylinder plate is the accuracy of the cylinder plate extending in the vertical direction. When the verticality of the cylinder plate is too large, it indicates that the cylinder plate has a large tilt angle in the vertical direction. At this time, if subsequent components are installed, it will cause the overall structure of the drying tower to tilt, thereby affecting the working performance and service life of the drying tower. Therefore, it is necessary to strictly control the verticality of each cylinder plate.

[0045] S33. When the verticality of the cylindrical plate is not greater than the preset verticality, the cylindrical plate and the lower cone are fixedly connected, and at least two adjacent cylindrical plates are fixedly connected.

[0046] Specifically, the preset verticality is 5mm.

[0047] It is understood that when the verticality of the cylinder plate is less than 5mm, it means that the verticality of the cylinder plate is not greater than the preset verticality. At this time, the lower cone and the two adjacent cylinder plates can be fixedly connected to realize the installation of the cylinder.

[0048] In this embodiment, during the installation of the cylinder, multiple cylinder plates are sequentially hoisted onto the lower cone and positioned corresponding to the cone plate. The lower cone provides stable support and temporary fixation, facilitating subsequent adjustments to the verticality of the cylinder plates. Then, by checking the verticality of each cylinder plate and ensuring it does not exceed a preset verticality (5mm), the verticality of the installed cylinder meets design requirements, preventing excessive tilting and ensuring the overall structural stability of the drying tower. When the verticality of the cylinder plate meets the requirements, the cylinder plate and the lower cone are fixedly connected, with at least two adjacent cylinder plates fixedly connected to form a stable cylinder structure. This arrangement not only improves the installation accuracy of the cylinder but also ensures the overall installation quality of the drying tower. Furthermore, the use of multiple cylinder plates allows for step-by-step installation and testing, further improving the construction efficiency of the drying tower.

[0049] It should also be noted that the straightness of the cylinder must meet preset requirements during installation. Specifically, in a further embodiment of the present invention, the actual height of the cylinder in the vertical direction is h2, and the distance between the actual central axis of the cylinder in the vertical direction and the theoretical central axis of the drying tower in the vertical direction is d2, where d2 ≤ h2 / 200mm. This setting, by strictly controlling the straightness of the cylinder, effectively ensures the shape and positional accuracy of the cylinder, thereby guaranteeing the installation accuracy of subsequent components, as well as the installation stability and working performance of the drying tower.

[0050] In the fifth embodiment of the present invention, please refer to Figure 5 After step S30, which involves installing the cylinder onto the upper end face of the lower cone, the method further includes: S01. Adjust the distance between two adjacent cone plates and two adjacent cylindrical plates; Understandably, at this point, the lower cone and the cylinder need to be fixedly connected by welding. To ensure the welding quality and the accuracy of the cone and the cylinder, it is necessary to adjust the distance between two adjacent cone plates and two adjacent cylinder plates.

[0051] S02. Spot weld two adjacent cone plates and / or two adjacent cylinder plates to form multiple weld points between two adjacent cone plates and / or two adjacent cylinder plates; It is understandable that by using the face-shaped form of spot welding, the relative positions between two adjacent cone plates and / or two adjacent cylinder plates can be initially fixed, preventing the installation accuracy from being affected by component movement during subsequent full welding.

[0052] Furthermore, spot welding can be performed between two adjacent cone plates, between two adjacent cylindrical plates, or between a cone plate and a corresponding cylindrical plate.

[0053] It should be noted that during the spot welding process, it is necessary to ensure that the weld points are evenly distributed and of reliable quality.

[0054] It should also be noted that during the spot welding process, coarse spot welding can be performed first to form multiple coarse weld points, followed by fine spot welding to form multiple fine weld points. The distance between two adjacent coarse weld points is greater than the distance between two adjacent fine weld points. For example, coarse spot welding can be performed first, with a weld every 200mm along the vertical direction, followed by fine spot welding, with a weld every 40mm along the vertical direction. Further fine spot welding can then be performed, with a weld every 10mm along the vertical direction. This progressively finer spot welding ensures a more stable connection between adjacent cone plates and / or adjacent cylinder plates, and that the weld points are evenly distributed. This effectively prevents installation deviations caused by thermal stress concentration or minor component movements during subsequent full-scale welding, thereby further improving the overall installation accuracy of the drying tower.

[0055] S03. Tap the multiple solder joints in sequence; After spot welding, the corresponding weld points need to be tapped to release the stress at the weld points, thereby effectively preventing component deformation or cracking caused by stress concentration during subsequent full welding, and thus ensuring the overall structural stability and installation accuracy of the drying tower.

[0056] It should be noted that when performing coarse spot welding followed by fine spot welding, the order of tapping multiple weld points should be followed: coarse first, then fine. That is, the coarse weld points should be tapped first to release the large stress generated by the initial welding. After the coarse weld points are tapped, the fine spot welding should be performed, and the fine weld points should be tapped.

[0057] S04. Perform full welding on two adjacent cone plates and / or two adjacent cylinder plates.

[0058] With this setup, after spot welding and stress relief treatment of the weld points are completed, full welding is performed on the adjacent cone plates and / or the adjacent cylinder plates to ensure connection strength.

[0059] In this embodiment, after the cylinder is installed on the upper surface of the lower cone, the distance between adjacent cone plates and cylinder plates is adjusted to create favorable conditions for subsequent welding operations. A process flow of spot welding followed by full welding is adopted. The spot welding stage, through multiple rounds of coarse and fine welding, not only achieves initial fixation between components but also effectively disperses welding thermal stress through a progressively refined weld point layout. Simultaneously, the weld point tapping process is carried out in a coarse-to-fine manner to ensure targeted stress release, first eliminating larger stress concentration points and then addressing minor residual stress, thereby minimizing the risk of welding deformation and ultimately significantly improving the installation quality of the drying tower.

[0060] In the sixth embodiment of the present invention, please refer to Figure 6 Step S40, installing the tower top structure onto the upper end face of the cylinder, includes: S41. Install the tower top frame onto the upper end face of the cylinder; It is understood that the upper surface of the cylinder can provide stable support for the tower top.

[0061] S42. Install the multiple top plates onto the upper surface of the tower top frame in sequence, and fix the multiple top plates and the tower top frame together.

[0062] It is understandable that when installing the top plate, it is necessary to ensure that the connection between each top plate and the tower top frame is firm and stable, and that multiple top plates can jointly cover the through hole of the cylinder.

[0063] In this embodiment, when installing the tower top structure, the tower top frame is first securely installed onto the upper surface of the cylinder. The stable support provided by the cylinder ensures the positioning accuracy of the tower top frame. Then, multiple top plates are sequentially fixed to the upper surface of the tower top frame. This step-by-step installation facilitates adjustment of the connection position of each top plate and ensures that the multiple top plates together form a complete closed structure to cover the through-hole of the cylinder. This arrangement ensures the installation stability of the tower top structure and further improves construction efficiency.

[0064] In the seventh embodiment of the present invention, please refer to Figure 7 After step S40, which involves installing the tower top structure onto the upper end face of the cylinder, the method further includes: S50. Install the air distributor into the through hole of the tower top structure.

[0065] In this embodiment, by installing the air distributor into the through hole of the top structure of the tower, the air distributor can communicate with the interior of the drying tower, thereby enabling the air distributor to distribute the high-temperature airflow evenly and stably to various parts of the drying tower, thus ensuring that the drying tower can achieve sufficient and uniform heat exchange, thereby ensuring the drying effect and working performance of the drying tower.

[0066] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
