Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange drying equipment, and in particular to a tube spacing arrangement structure for a large heat exchange drying equipment. Background Technology

[0002] Large-scale heat exchange drying equipment is a core piece of equipment in many industrial production processes, including chemical, food, pharmaceutical, and building materials industries. It achieves drying or temperature control of materials through large-scale heat exchange between the heat medium inside the tubes and the materials outside. The key to the equipment's performance lies in the arrangement of its internal heat exchange tube bundles and the total heat exchange area. Therefore, how to efficiently and stably assemble and arrange a large number of heat exchange tubes, ensuring uniform spacing to optimize heat transfer and flow field distribution, and maximizing heat exchange efficiency per unit volume, is a crucial issue in the design and manufacture of large-scale heat exchange drying equipment.

[0003] In existing technologies, the installation of heat exchange tubes in large-scale heat exchange drying equipment typically employs a method of integral or split frame welding and bolt fixing. A typical structure involves passing a large number of heat exchange tubes through pre-drilled, heavy tube sheets or multi-layered support beams, and fixing the ends of the tubes to the tube sheet by welding or expansion joints, forming an integral tube bundle module. When multiple such tube bundle modules need to be installed to construct a large heat exchange matrix, workers need to use hoisting equipment to lift the heavy modules one by one to the designated location inside the equipment, and then use a large number of high-strength bolts and nuts to connect and secure the module's frame or tube sheet flanges to the main frame of the equipment or adjacent modules.

[0004] However, the aforementioned traditional assembly methods suffer from serious problems in terms of positioning accuracy and installation efficiency. Their core drawback lies in the extreme reliance on manual alignment and cumbersome tool operations throughout the installation process, lacking a mechanism for rapid positioning and tightening. When assembling multiple heat exchanger tube bundle modules weighing hundreds of kilograms or even several tons on-site, precisely aligning them and maintaining the correct spacing is a time-consuming and labor-intensive task, often requiring multiple people to collaborate and repeatedly adjust using measuring tools. The alignment process is slow and prone to accumulating errors. Furthermore, the use of numerous bolts for fixing not only requires workers to carry heavy tools to tighten them one by one in confined spaces, but also makes it difficult to ensure uniform preload on all bolts, directly affecting the stability and sealing of the entire structural connection. This inefficient installation method significantly extends the construction and maintenance cycle of the equipment, substantially increases labor costs and downtime, and severely restricts production efficiency. Therefore, a tube spacing arrangement structure for large-scale heat exchange drying equipment is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tube spacing arrangement structure for a large heat exchange drying equipment. It aims to improve the existing technology where tube spacing arrangement structures often use a large number of bolts for fixing. This not only requires workers to carry heavy tools to tighten them one by one in a narrow space, but also makes it difficult to ensure that the preload of all bolts is uniform. This directly affects the stability and sealing of the entire structure connection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tube spacing arrangement structure for a large heat exchange drying equipment, including a mounting plate one, a heat exchange tube fixedly connected inside the mounting plate one, a mounting plate two fixedly connected to the outer wall of the heat exchange tube, a positioning column fixedly connected to the upper surface of the mounting plate two, a positioning hole for installing the positioning column penetrating through the interior of the mounting plate one, and a quick-installation component installed on the upper surface of the mounting plate two;

[0007] The quick-installation assembly includes a plug rod, the lower end of which is fixedly connected to the upper surface of the mounting plate two. A sliding block is slidably connected to the inner wall of the plug rod. A telescopic rod is fixedly connected to the lower surface of the sliding block. A spring is sleeved on the outer wall of the telescopic rod. A hinge seat is fixedly connected to the upper surface of the sliding block. A symmetrical rotating plate one is rotatably connected to one side of the outer wall of the hinge seat. A locking block is rotatably connected to the outer wall of the rotating plate one. A hinge block is rotatably connected to the inner wall of the locking block.

[0008] As a further description of the above technical solution:

[0009] An outer sleeve corresponding to the insertion rod is fixedly connected to the upper surface of the mounting plate, and a rotating shaft is rotatably connected inside the outer sleeve.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The inner sleeve has symmetrical wedges fixedly connected to its inner wall, and the outer wall of the inner sleeve is rotatably connected to the inner wall of the outer sleeve.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the wedge block is in contact with the outer wall of the locking block and rotates, and the wedge block is used to drive the locking block to retract into the insertion rod.

[0017] The bottom end of the telescopic rod sleeve is fixedly connected to the bottom wall of the inner cavity of the insertion rod, and the upper end of the telescopic rod piston rod is fixedly connected to the lower surface of the sliding block.

[0018] As a further description of the above technical solution:

[0019] The lower end of the spring is fixedly connected to the bottom wall of the inner cavity of the insertion rod, and the upper end of the spring is fixedly connected to the lower surface of the sliding block.

[0021] The outer wall of the insertion rod is disposed inside the mounting plate, and the outer wall of the insertion rod is disposed inside the inner sleeve.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, multiple vertically arranged heat exchange tubes increase the heat exchange area. When assembling multiple sets of mounting plates, mounting plate one on one side of one mounting plate is fitted with a positioning hole and installed on the outer wall of the positioning column on the upper side of another mounting plate, thus facilitating quick positioning of multiple sets of mounting plates. At the same time, inserting a rod into the mounting plate one facilitates quick assembly by using the reaction force of a spring to engage the locking block above the mounting plate one, thereby improving the practicality of the equipment.

[0024] 2. In this utility model, by setting an outer sleeve corresponding to the insertion rod, the inner sleeve is driven to rotate by rotating the knob. At this time, the rotation of the inner sleeve facilitates the wedge block to push and squeeze the clamping block. Through the movement of the wedge block, the clamping block is squeezed into the insertion rod, thereby achieving the effect of removing multiple sets of mounting plates without the use of tools, thus improving the practicality of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-6This utility model provides an embodiment of a tube spacing arrangement structure for a large-scale heat exchange drying equipment, including a mounting plate 1. Mounting plate 1 serves as a reference connecting plate for heat exchange units, used for modular assembly. Heat exchange tubes 3 are fixedly connected inside mounting plate 1. These heat exchange tubes 3 are the core working components for heat transfer, and multiple heat exchange tubes 3 are arranged longitudinally and transversely. The transverse spacing of the multiple heat exchange tubes 3 is 122mm, and the longitudinal spacing is 90mm. The number of heat exchange tubes 3 can be adjusted according to specific usage requirements. By using the specified arrangement values, the heat exchange efficiency can be improved. Mounting plate 2 is fixedly connected to the outer wall of the heat exchange tubes 3, providing a quick-assembly assembly. A stable mounting base is provided. A positioning post 4 is fixedly connected to the upper surface of mounting plate 2. This positioning post 4 serves as a male alignment structure, inserted into the positioning holes 5 of adjacent units to ensure precise spacing. A positioning hole 5 is drilled through the interior of mounting plate 1 for mounting the positioning post 4. This positioning hole 5 serves as a female alignment structure, cooperating with the positioning post 4 to achieve quick and precise modular alignment. A quick-release assembly is mounted on the upper surface of mounting plate 2. The quick-release assembly includes a rod 6, which is the actuator that passes through mounting plate 1 and locks in place. The lower end of the rod 6 is fixedly connected to the upper surface of mounting plate 2. A sliding block 7 is slidably connected to the inner wall of the rod 6. This sliding block 7 is the actuator inside the quick-release assembly, and its axial movement controls the opening and closing of the locking block 12. A telescopic rod 8 is fixedly connected to the lower surface of the sliding block 7. The telescopic rod 8 provides stable guidance for the reciprocating motion of the sliding block 7. A spring 9 is sleeved on the outer wall of the telescopic rod 8. The spring 9 provides continuous return force to the sliding block 7 and is the power source for automatic locking. A hinge seat 10 is fixedly connected to the upper surface of the sliding block 7. The hinge seat 10 is used to connect the sliding block 7 and the linkage mechanism. A symmetrical rotating plate 11 is rotatably connected to one side of the outer wall of the hinge seat 10. The rotating plate 11 acts as a linkage, converting the linear motion of the sliding block 7 into the radial motion of the locking block 12. The locking block 12 is rotatably connected to the outer wall of the rotating plate 11. The locking block 12 is the final locking claw that directly engages with the mounting plate 11 to achieve locking. The inner wall of the locking block 12 rotates. A hinge block 13 is connected; this hinge block 13 serves as an intermediate hinge, ensuring the flexibility of motion transmission; the bottom end of the telescopic rod 8 sleeve is fixedly connected to the bottom wall of the inner cavity of the insert rod 6, and the upper end of the piston rod of the telescopic rod 8 is fixedly connected to the lower surface of the sliding block 7; this structure clarifies the assembly relationship of the telescopic rod 8, ensuring stable support and guidance for the sliding block 7; the lower end of the spring 9 is fixedly connected to the bottom wall of the inner cavity of the insert rod 6, and the upper end of the spring 9 is fixedly connected to the lower surface of the sliding block 7; this structure clarifies the installation position of the spring 9, enabling it to effectively apply an upward thrust to the sliding block 7; the outer wall of the insert rod 6 penetrates the interior of the mounting plate 1, which is the basis for locking one heat exchange unit to another unit, and the outer wall of the insert rod 6 is located inside the inner sleeve 17. This structure indicates that there is an assembly and functional cooperation between the insert rod 6 and the inner sleeve 17 for unlocking.

[0035] Specifically, the precise installation distance between multiple heat exchange tubes 3 is ensured in advance through the cooperation of the positioning pin 4 and the positioning hole 5. On this basis, when the insertion rod 6 representing one unit is inserted into the mounting plate 1 of another unit, the internal spring 9 will automatically push the sliding block 7, and through the hinge seat 10 and the rotating plate 11, the two locking blocks 12 will be pushed outward, so that they will automatically pop out and lock after passing the mounting plate 1, thereby achieving instant locking without any tools.

[0036] Reference Figures 1-6 An outer sleeve 14 corresponding to the insertion rod 6 is fixedly connected to the upper surface of the mounting plate 1. The outer sleeve 14 serves as the fixed base and outer shell of the unlocking mechanism, providing support and limiting for the internal rotating components. A rotating shaft 15 is rotatably connected inside the outer sleeve 14. The rotating shaft 15 is the core transmission rod that transmits the unlocking operation, converting the rotational motion at the top into the motion of the internal mechanism. A knob 16 is fixedly connected to the upper end of the rotating shaft 15. The knob 16 is the human-machine interface for the unlocking operation, allowing the operator to apply torque without tools. An inner sleeve 17 is fixedly connected to the lower end of the rotating shaft 15. The inner sleeve 17 is the direct actuator for the unlocking action. The rotation of the inner sleeve 17 causes the wedge 18 to move synchronously. Symmetrical wedges 18 are fixedly connected to the inner wall of the inner sleeve 17. These wedges 18 are key components for converting the force direction; their inclined structure converts the circular motion of the inner sleeve 17 into a radial thrust on the locking block 12. The outer wall of the inner sleeve 17 is rotatably connected to the inner wall of the outer sleeve 14. This structure ensures that the inner sleeve 17 can stably rotate around the insertion rod 6. The outer wall of the wedge 18 rotates in contact with the outer wall of the locking block 12; this is the point of application of the unlocking force, ensuring that the rotational input force can be effectively applied to the locking block 12. The wedge 18 drives the locking block 12 to retract into the insertion rod 6. This is the final unlocking action, releasing the locking state between the locking block 12 and the mounting plate 1 by forcibly retracting it.

[0037] Specifically, by turning the knob 16 on top, the operator transmits the rotational motion precisely to the inner sleeve 17 via the rotating shaft 15. The wedge 18 fixed to the inner sleeve 17 rotates accordingly, and its inclined structure applies a radial, inward pressure to the locked latch 12, forcing it to overcome the spring 9 force of the self-locking mechanism and retract into the insert 6. This process efficiently converts a simple rotational motion into a linear driving force sufficient to unlock, thereby achieving quick and convenient disassembly and greatly improving the maintainability of the equipment.

[0038] Working Principle: When using this heat exchange drying equipment, during the assembly of a large heat exchange drying device, the positioning pin 4 of the mounting plate 2 on one heat exchange unit is first inserted into the positioning hole 5 of the mounting plate 1 on the adjacent unit to achieve rapid initial alignment between multiple heat exchange tube 3 modules, ensuring the accuracy of the tube spacing. After alignment, the insertion rod 6 of the quick-installation assembly fixed above the heat exchange tube 3 is passed through the mounting plate 1. During the passage, the locking block 12 located inside the insertion rod 6 is squeezed inward by the hole wall of the mounting plate 1. When the insertion rod 6 has completely passed through, the locking block 12 passes over the upper surface of the mounting plate 1 and is no longer constrained by the hole wall. At this time, the spring 9 inside the insertion rod 6 immediately extends and pushes the sliding block 7 upward. The sliding block 7, through the linkage of the hinge seat 10 and the rotating plate 11, pushes the two symmetrical locking blocks 12 outward, making them firmly locked on the upper surface of the mounting plate 1, thus completing the rapid and automatic locking of a heat exchange tube 3 without any tools.

[0039] Secondly, when it is necessary to repair or replace the heat exchange tube 3, the operator only needs to turn the knob 16 installed above the mounting plate 1. The knob 16 drives the inner sleeve 17 to rotate inside the fixed outer sleeve 14 through the rotating shaft 15. As the inner sleeve 17 rotates, the wedge 18 fixed on its inner wall will contact and slide against the outer wall of the extended locking block 12. The inclined structure of the wedge 18 will apply an inward pushing force to the locking block 12, forcing it to overcome the elastic force of the spring 9 and retract inward, and drive the sliding block 7 to move down. When the locking block 12 is fully squeezed and retracted into the insertion rod 6, its engagement with the mounting plate 1 is released. At this time, the entire quick-release assembly, along with its fixed heat exchange tube 3, can be easily pulled out from the mounting plate 1, realizing quick and tool-free disassembly.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
