[0002] A two-stage heat exchanger in the conventional island of a nuclear power plant is a critical large-scale modular vessel in the plant's secondary circuit's "four components and one cooling system." It is a crucial component for improving the plant's overall thermal efficiency and protecting the steam turbines. This equipment has a complex internal structure, with numerous, large, and heavy components. These components include the shell assembly, separator, lower lining, and steam distributor. The shell assembly is approximately 16 meters long; the separator is a rectangular block, approximately 15.8 meters long and weighs approximately 35 tons; the lower lining is a circular arc plate, also approximately 15.8 meters long and weighs approximately 4 tons; and the steam distributor is a cylindrical unit with a diameter of approximately 2 meters. The two components weigh approximately 2 tons in total.
[0003] In the prior art, two steam distributors are first installed into the large connecting pipe of the shell assembly, adjusted into position and welded, and then the three sections of the lower liner are installed into the shell assembly in sections, followed by welding the three sections of the lower liner, and then the separator is installed into the shell assembly, and finally the four drain pipe assemblies at the bottom of the separator are welded.
[0004] In the prior art, the internal components are hoisted in multiple times, which results in a long product manufacturing cycle. In addition, workers spend a long time working inside the shell, and the working environment is harsh. Utility Model Content
[0005] In order to overcome the problems existing in the prior art, the purpose of the present utility model is to provide a heat exchanger component and an installation device.
[0006] The technical solution adopted by the present invention to solve the technical problem is: a heat exchanger component, comprising:
[0007] Internal components and external components;
[0008] The outer component is provided with a cavity, one end of which is provided with an opening through which the inner component can pass. The cavity and the opening now correspond to the shape of the inner component. The inner wall of the cavity is provided with a limit portion along the length direction of the cavity, and the outer side of the inner component is provided with a slide bar that cooperates with the limit portion.
[0009] The internal components include a separator, a lower liner, and a steam distributor;
[0010] The slide bar is arranged on the outer side of the lower part, both sides of the separator are fixedly connected to the lower lining, and the steam distributor is fixedly connected to the separator.
[0011] Main Working Principle: It consists of an outer assembly and an inner assembly. The inner assembly includes a separator, lower liner, and steam distributor. These components are fixed together to form a single unit, ensuring stability and reliability during assembly and use. The outer assembly has a cavity with an opening at one end to accommodate the inner assembly. The size of the cavity and opening corresponds to the size of the inner assembly to ensure smooth insertion.
[0012] The inner wall of the outer assembly's cavity is provided with a limiter along its length, while the outer side of the inner assembly (specifically, the lower outer side) is provided with a slide bar that interacts with the limiter. This design allows the inner assembly to be smoothly and accurately inserted into the outer assembly's cavity during assembly, guided by the slide bar and the limiter.
[0013] When assembling the heat exchanger components, the inner assembly (including the separator, lower liner, and steam distributor) is first prepared as a whole. Next, the inner assembly is aligned with the cavity opening of the outer assembly, ensuring that the slide bar and the stopper are aligned. The inner assembly is then slowly and smoothly inserted into the cavity of the outer assembly using the installation equipment, guided by the slide bar and the stopper. During the insertion process, the interaction between the slide bar and the stopper ensures the stability and accuracy of the inner assembly, preventing deviation or tilting. Once the inner assembly is fully inserted into the cavity of the outer assembly, the heat exchanger components are assembled.
[0014] The heat exchanger components of the present invention are assembled by first assembling the internal components, thereby reducing the difficulty of installation. Through the precise matching of the internal and external components and the guiding mechanism of the slide bar and the limit part, an efficient and accurate assembly process is achieved.
[0015] In summary, the heat exchanger component of the present invention achieves precise matching and efficient assembly between internal and external components through its unique design and working principle.
[0016] Preferably, the limiting portions are provided on both sides of the cavity, and the sliding strips are provided on both sides of the lower lining.
[0017] Preferably, the limiting portion includes a top edge and a bottom edge, the top edge is placed above the bottom edge, a pulley is provided on the surface of the bottom edge, and the slide bar is located between the top edge and the pulley.
[0018] Preferably, a hanging ear is provided on the top of the separator, and a plurality of the hanging ears are provided along the length direction of the separator.
[0019] Preferably, a sliding cavity is provided on the upper portion of the outer component along the length direction.
[0020] An installation device for assembling any of the above-mentioned heat exchanger components, comprising:
[0021] First bracket, second bracket, slide rail, lifting assembly;
[0022] The first bracket and the second bracket are arranged opposite to each other, and the first bracket connects the outer component; the two ends of the slide rail are respectively connected to the first bracket and the second bracket, the hoisting component is slidably connected to the slide rail, and the lower end of the hoisting component is connected to the inner component, and the hoisting component transports the inner component into the cavity along the direction of the slide rail.
[0023] Main Working Principle: The first and second brackets are positioned opposite each other, providing stable support for the entire installation. The first bracket connects to the outer components, ensuring their stability during installation. The ends of the slide rails connect to the first and second brackets, respectively, forming a stable track system. The design of the slide rails allows the lifting components to move smoothly along their path. The lifting component is connected to the slide rails in a sliding manner, meaning it can move freely on the rails. The lower end of the lifting component connects to the inner components for lifting and transporting.
[0024] Before starting assembly, first make sure that the first bracket is firmly connected to the outer component and that the slide rail is correctly installed between the first bracket and the second bracket. Next, connect the lifting component to the inner component. Connect the inner component through the lifting component to ensure that the inner component will not fall off or be damaged during the lifting process. Then, start the lifting component to drive the inner component to move along the direction of the slide rail. When the lifting component moves to the predetermined position (that is, the cavity of the outer component), stop moving and slowly place the inner component into the cavity. During this process, the lifting component may need to be fine-tuned to ensure that the inner component can be accurately aligned with the cavity and inserted smoothly. Finally, when the inner component is completely placed in the cavity, release the connection between the lifting component and the inner component to complete the assembly process.
[0025] The installation equipment of this utility model realizes efficient and accurate installation of internal components through the cooperation of slide rails and lifting components. The design of the slide rails ensures the stability and accuracy of the lifting components during movement, reducing the error rate and damage risk during assembly.
[0026] In summary, the installation device of the present invention provides an efficient and accurate solution for the assembly of heat exchanger components through its unique design and working principle, thereby improving assembly efficiency and product quality.
[0027] Preferably, the hoisting assembly includes an electric hoist and a hanging point, the upper end of the electric hoist is slidably connected to the slide rail, the hanging point is connected to the lower end of the electric hoist, and the hanging point and the separator are fixedly matched with each other.
[0028] Preferably, the hoisting assembly further includes a connecting rod, the connecting rod and the slide rail are parallel to each other, the connecting rod is connected to the lower end of the electric hoist, and the hanging points are provided at both ends of the connecting rod.
[0029] Compared with the prior art, the beneficial effects of the present invention are:
[0030] 1. The utility model ensures stability and reliability during use by fixing the separator, lower lining and steam distributor in the inner component to form a whole, thereby reducing the difficulty of installation. The cavity and opening size of the outer component correspond to the size of the inner component, ensuring that the inner component can be accurately and unobstructedly inserted into the cavity of the outer component. At the same time, the limiting part provided on the inner wall of the cavity cooperates with the sliding bar on the outside of the inner component, further improving the accuracy and stability of the assembly. Due to the precise fit between the inner and outer components, and the guiding mechanism of the sliding bar and the limiting part, the assembly process is more efficient and quick. This greatly reduces the time and labor costs required for assembly and improves production efficiency.
[0031] 2. The mounting device provided by this utility model is specifically designed for assembling the aforementioned heat exchanger components. The relative positioning of the first and second brackets, and the secure connection of the slide rails to them, provide a stable travel path for the hoisting assembly. This ensures that the inner assembly maintains precise positioning during transport, allowing for accurate insertion into the cavity of the outer assembly. The mounting device, through the sliding connection between the hoisting assembly and the slide rails, enables rapid and smooth transport of the inner assembly. This design significantly shortens assembly time and improves production efficiency, making it particularly suitable for large-scale production environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of this application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0038] Example 1
[0039] This embodiment discloses a heat exchanger component, such as Figure 1 As shown, the heat exchanger assembly includes an inner component 1 and an outer component 2. The outer component 2 is designed with a cavity 20, which is open at one end and has a shape that matches the inner component 1. A limiter 21 is provided along the inner wall of the cavity 20 along its length, while a slide 10 that mates with the limiter 21 is provided on the outer side of the inner component 1. The inner component 1 includes a separator 11, a lower liner 12, and a steam distributor 13. The slide 10 is provided on the outer side of the lower liner 12. The separator 11 is fixedly connected to the lower liner 12 on both sides, and the steam distributor 13 is fixedly connected to the separator 11.
[0040] During assembly, the inner component 1's outer slide 10 cooperates with the stopper 21 on the inner wall of the outer component 2's cavity 20, achieving precise alignment and stable sliding. This design ensures that the inner component 1 can be accurately and unobstructedly inserted into the outer component 2's cavity 20, forming a tight fit. The cooperation between the slide 10 and the stopper 21 ensures precise alignment and a stable connection between the inner and outer components 1 and 2.
[0041] In some optional embodiments, stoppers 21 are provided on both sides of cavity 20, and slide bars 10 are also provided on both sides of lower lining 12. When inner component 1 is inserted into cavity 20 of outer component 2, the slide bars 10 on both sides engage with the stoppers 21 on either side of cavity 20, further improving assembly accuracy and stability. The cooperation between the two-sided slide bars 10 and the stoppers 21 makes inner component 1 more stable during insertion and reduces the possibility of misalignment.
[0042] In some optional embodiments, the retaining portion 21 includes a top edge 210 and a bottom edge 211. The top edge 210 is positioned above the bottom edge 211, and a pulley 212 is provided on the surface of the bottom edge 211. The slider 10 is positioned between the top edge 210 and the pulley 212. During assembly, the slider 10 slides along the track between the top edge 210 and the pulley 212, ensuring smooth assembly between the inner component 1 and the outer component 2. The design of the pulley 212 reduces friction and resistance during the sliding process.
[0043] The design of the pulley 212 reduces the friction between the slide bar 10 and the limiting portion 21 , making the assembly process smoother.
[0044] In some optional embodiments, a hanging lug 110 is provided on the top of the separator 11, and multiple hanging lugs 110 are provided along the length of the separator 11. The design of the hanging lug 110 facilitates the use of lifting tools or other auxiliary equipment to lift or move the separator 11 and the connected inner component 1 during assembly or maintenance.
[0045] In some optional embodiments, a sliding cavity 22 is provided along the length of the upper portion of the outer component 2. The sliding cavity 22 is a space for the lifting component 6 to slide and move, allowing the lifting component 6 to move within the outer component 2 with sufficient space to transfer the inner component 1 to the cavity 20.
[0046] Example 2
[0047] This embodiment provides a mounting device such as Figure 2 As shown, it is mainly used to assemble the heat exchanger components in Example 1. The installation equipment includes a first bracket 3, a second bracket 4, a slide rail 5 and a hoisting assembly 6. The first bracket 3 and the second bracket 4 are arranged relative to each other to provide a stable support structure. The first bracket 3 is connected to the outer component 2 of the heat exchanger to ensure that the outer component 2 is fixed in position during the installation process. The two ends of the slide rail 5 are respectively connected to the first bracket 3 and the second bracket 4 to form a stable rail system, allowing the hoisting assembly 6 to slide thereon. The hoisting assembly 6 is slidably connected to the slide rail 5, and the lower end of the hoisting assembly 6 is connected to the inner component 1 of the heat exchanger. By moving the hoisting assembly 6 along the direction of the slide rail 5, the inner component 1 is accurately transported to the cavity 20 of the outer component 2, thereby realizing the effective assembly of the inner and outer components 2.
[0048] This design improves assembly efficiency and accuracy, reduces manpower requirements, and at the same time ensures safety during the assembly process, avoiding injuries or accidents caused by improper manual operation.
[0049] In some optional embodiments, the hoist assembly 6 includes an electric hoist 60 and a hanging point 61. The upper end of the electric hoist 60 is slidably connected to the slide rail 5, and is electrically driven to achieve smooth movement along the slide rail 5. The hanging point 61 is connected to the lower end of the electric hoist 60 and is used to secure and suspend the inner assembly 1. The hanging point 61 is fixedly engaged with the separator 11 (i.e., part of the inner assembly 1) to ensure the stability and accuracy of the inner assembly 1 during transportation and assembly.
[0050] The use of the electric hoist 60 greatly reduces the labor intensity of manual operation and improves the efficiency and accuracy of the hoisting. The design of the hanging point 61 ensures the safe fixation of the inner component 1 during the hoisting process, avoiding damage or safety accidents caused by shaking or falling off.
[0051] In some optional embodiments, a connecting rod 62 is parallel to the slide rail 5 and connected to the lower end of the electric hoist 60. Connecting rod 62 is provided with attachment points 61 at both ends for simultaneously connecting and securing multiple parts of the inner assembly 1. The design of connecting rod 62 enhances the stability and load-bearing capacity of the hoist assembly 6, making the hoisting of large or heavy inner assemblies 1 safer and more reliable. The presence of attachment points 61 at both ends increases the flexibility of the hoisting process, accommodating inner assemblies 1 of varying shapes and sizes, and improving the versatility and adaptability of the installation equipment.
[0052] In summary, this installation device, through the ingenious combination of the first bracket 3, the second bracket 4, the slide rail 5, and the hoist assembly 6, achieves efficient and precise assembly of the heat exchanger's internal and external components 2. The use of the electric hoist 60 and the hanging point 61 reduces manual labor and improves safety and efficiency. The addition of the connecting rod 62 further enhances the stability and versatility of the hoist assembly 6, making the entire installation process smoother and more reliable.
[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
