Description

Technical Field

[0001] This utility model relates to the field of tubular heat exchanger technology, and in particular to a novel combined tubular heat exchanger. Background Technology

[0002] Tubular heat exchangers are a common type of heat exchange equipment, widely used in chemical, petroleum, HVAC, and energy industries. Their main function is to transfer heat from one fluid to another without mixing the two fluids during the heat exchange process. In short, tubular heat exchangers are highly efficient and widely used heat exchange equipment that can work efficiently and reliably in a variety of industrial environments.

[0003] Chinese patent discloses a combined tube heat exchanger (authorization announcement number CN219624538U). This patented technology, through the setting of scraper and other structures, after the combined tube heat exchanger has been used for a certain period of time, the rotating rod driven by the motor rotates, thereby driving the scraper to clean the inner wall of the heat exchange pipes. This prevents dirt and other difficult-to-clean dirt from adhering to the inner wall, effectively avoiding the problems of current combined tube heat exchangers where the internal pipes are usually in a closed state, making it inconvenient to clean the internal pipes. The pipe walls of the internal pipes will also accumulate a lot of dust and impurities due to long-term use, which will affect the normal use of the heat exchanger and cause certain inconveniences.

[0004] However, most existing tubular heat exchangers use bolts to install the sealing cap, resulting in slow installation efficiency and hindering internal maintenance. For example, the aforementioned comparative document uses bolt installation. In practical applications, the large number of bolts required for connecting the sealing cap to the tubular heat exchanger makes disassembly inconvenient, impacting maintenance and reducing practicality. Therefore, those skilled in the art have proposed a novel combined tubular heat exchanger to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a novel combined tubular heat exchanger that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel combined tubular heat exchanger includes: a tubular heat exchanger body and a first connecting plate fixed to both ends of the tubular heat exchanger body. A sealing cap is connected to one end of the first connecting plate, and a second connecting plate is connected to one side of the sealing cap near the first connecting plate. Mounting plates are installed on both the upper and lower surfaces of the first connecting plate. An electric lifting rod is provided on the upper surface of the mounting plate above the second connecting plate, and a fixing groove is provided inside the mounting plate. A positioning plate is provided inside the fixing groove, and limiting rods are symmetrically arranged on the lower surface of the positioning plate. Limiting holes are provided on the upper surface of the second connecting plate. Jackets are symmetrically arranged on the outside of the tubular heat exchanger body, and supports are fixed to the outside of the jackets. A lifting plate is installed on the lower surface of the supports, and a base plate is provided on the lower surface of the lifting plate. Hydraulic lifting rods are symmetrically arranged on the upper surface of the base plate.

[0007] As a further technical solution of this utility model, two limiting rods are symmetrically arranged on the lower surface of the positioning plate, and the lower end of the limiting rod is embedded in the interior of the limiting hole.

[0008] As a further technical solution of this utility model, the fixed end of the electric lifting rod is installed on the upper surface of the mounting plate, and the telescopic end of the electric lifting rod is connected to the middle position of the upper surface of the positioning plate.

[0009] As a further technical solution of this utility model, the first connecting plate and the second connecting plate are the same size, and a sealing gasket is also provided on one side of the second connecting plate near the first connecting plate.

[0010] As a further technical solution of this utility model, the fixed end of the hydraulic lifting rod is installed on the upper surface of the base plate, and the telescopic end of the hydraulic lifting rod is connected to a fixing plate, which is installed on the upper surface of the lifting plate by bolts.

[0011] As a further technical solution of this utility model, guide rods are symmetrically arranged on the upper surface of the base plate, and the upper end of the guide rods penetrates the upper surface of the lifting plate.

[0012] This utility model provides a novel combined tubular heat exchanger, which has the following advantages compared with the prior art:

[0013] 1. This design presents a novel combined tubular heat exchanger. An electric lifting rod on the mounting plate operates, causing the positioning plate to rise and fall within the fixed groove, contacting the second connecting plate. This allows the limiting rod to embed into the limiting hole, achieving a rapid and sealed connection between the first and second connecting plates. This also connects the main body of the tubular heat exchanger to the sealing cover. This design is simple in structure, easy to install and disassemble, facilitating the normal use and cleaning of the tubular heat exchanger, and demonstrating good practicality.

[0014] 2. This design presents a novel combined tubular heat exchanger. The jacket, support, and lifting plate provide support for the main body of the tubular heat exchanger. Furthermore, the symmetrically arranged hydraulic lifting rods work synchronously to raise and lower the lifting plate, thereby adjusting the height of the main body of the tubular heat exchanger. This facilitates the installation of the main body of the tubular heat exchanger and makes it highly practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a novel combined tubular heat exchanger technical solution, comprising: a tubular heat exchanger body 1 and first connecting plates 11 fixed at both ends of the tubular heat exchanger body 1. One end of the first connecting plate 11 is also connected to a sealing cover 2. A second connecting plate 21 is also connected to one side of the sealing cover 2 near the first connecting plate 11. Mounting plates 3 are installed on both the upper and lower surfaces of the first connecting plate 11. An electric lifting rod 31 is provided on the upper surface of the mounting plate 3 above the second connecting plate 21. A fixing groove 33 is provided inside the mounting plate 3. A positioning plate 32 is provided inside the fixing groove 33. Limiting rods are symmetrically provided on the lower surface of the positioning plate 32. 34. A limiting hole 22 is opened on the upper surface of the second connecting plate 21. A jacket 44 is symmetrically arranged on the outside of the tubular heat exchanger body 1. A support 42 is fixed on the outside of the jacket 44. A lifting plate 41 is installed on the lower surface of the support 42. A base plate 4 is provided on the lower surface of the lifting plate 41. A hydraulic lifting rod 45 is symmetrically arranged on the upper surface of the base plate 4. This arrangement utilizes the fact that mounting plates 3 are installed on both the upper and lower surfaces of the first connecting plate 11. The electric lifting rod 31 set on the mounting plate 3 will cause the positioning plate 32 to rise and fall, thereby allowing the limiting rod 34 to be embedded into the limiting hole 22, thereby quickly sealing the tubular heat exchanger body 1 and the sealing cover 2.

[0021] like Figure 2 As shown, two limiting rods 34 are symmetrically arranged on the lower surface of the positioning plate 32, and the lower end of the limiting rod 34 is embedded in the limiting hole 22. This arrangement enables the quick connection between the first connecting plate 11 and the second connecting plate 21 by embedding the limiting rod 34 into the limiting hole 22.

[0022] like Figure 2 As shown, the fixed end of the electric lifting rod 31 is installed on the upper surface of the mounting plate 3, and the telescopic end of the electric lifting rod 31 is connected to the middle position of the upper surface of the positioning plate 32. This arrangement allows the positioning plate 32 to rise and fall inside the fixing groove 33 by the operation of the electric lifting rod 31, thereby enabling the second connecting plate 21 to be positioned by the positioning plate 32.

[0023] like Figure 2 As shown, the first connecting plate 11 and the second connecting plate 21 are the same size. A sealing gasket is also provided on one side of the second connecting plate 21 near the first connecting plate 11. This setting uses the sealing gasket to ensure the sealing of the connection between the first connecting plate 11 and the second connecting plate 21.

[0024] like Figure 3As shown, the fixed end of the hydraulic lifting rod 45 is installed on the upper surface of the base plate 4, and the telescopic end of the hydraulic lifting rod 45 is connected to a fixing plate 46. The fixing plate 46 is installed on the upper surface of the lifting plate 41 by bolts. Guide rods 43 are also symmetrically arranged on the upper surface of the base plate 4. The upper end of the guide rod 43 penetrates the upper surface of the lifting plate 41. This arrangement utilizes the synchronous operation of the two hydraulic lifting rods 45 to make the fixing plate 46 rise and fall on the base plate 4. This allows the lifting plate 41 to be guided to rise and fall outside the guide rod 43, thereby increasing the height of the tubular heat exchanger body 1 to facilitate the installation of pipes and the tubular heat exchanger body 1.

[0025] The working principle of this utility model is as follows: When the combined tubular heat exchanger of this utility model is in use, the synchronous operation of the two hydraulic lifting rods 45 causes the fixed plate 46 to rise and fall on the base plate 4. This allows the lifting plate 41 to be guided and raised outside the guide rod 43, thereby increasing the height of the tubular heat exchanger body 1 to facilitate the installation of the pipes and the tubular heat exchanger body 1. When connecting the tubular heat exchanger body 1 to the sealing cover 2, the first connecting plate 11 and the second connecting plate 21 are connected accordingly. Then, the electric lifting rod 31 is started by an external power source. This causes the positioning plate 32 to rise and fall inside the fixing groove 33 and contact the second connecting plate 21. The limiting rod 34 is then embedded into the limiting hole 22 to achieve a quick sealing connection between the first connecting plate 11 and the second connecting plate 21, that is, to achieve the connection between the tubular heat exchanger body 1 and the sealing cover 2, thereby ensuring the normal use of the tubular heat exchanger body 1 and making it highly practical.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
