Description

Technical Field

[0001] This utility model relates to the technical field of heat exchangers, and in particular to shock-resistant buffer tubular heat exchangers. Background Technology

[0002] Heat exchangers are indispensable key equipment in industrial production, widely used in chemical, petroleum, power, food processing and other fields. Their main function is to transfer heat from one fluid to another to meet process requirements. Tubular heat exchangers occupy an important position among various types of heat exchangers due to their simple structure, high heat exchange efficiency, and strong pressure resistance.

[0003] However, in practical applications, traditional tubular heat exchangers tend to create stagnant areas when the fluid flows outside the heat exchange tubes, causing impurities in the fluid to easily deposit on the surface of the heat exchange tubes, forming fouling. This not only reduces heat exchange efficiency but also increases the energy consumption of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a shock-resistant and buffered tubular heat exchanger that improves heat exchange efficiency and reduces equipment energy consumption.

[0005] The shock-resistant and buffered tubular heat exchanger of this utility model includes:

[0006] The heat exchanger shell and the flow guiding assembly are arranged as follows: The heat exchanger shell is mounted on the support assembly. Fixed tube sheets are rotatably mounted at both ends of the heat exchanger shell shaft cavity. Multiple sets of mounting holes are symmetrically arranged on the fixed tube sheets. Heat exchange tube bundles are installed in the mounting holes arranged coaxially on the two sets of fixed tube sheets. A fixing element is installed on the fixed tube sheet at the input end of the heat exchanger shell. A tube box is mounted on the fixing element by bolts. A partition plate is installed inside the tube box. The partition plate is mounted on the fixed tube sheet and divides the multiple sets of heat exchange tube bundles symmetrically arranged on the fixed tube sheet into two groups. A shaft hole is provided on the tube box. The partition plate divides the inner cavity of the tube box into two groups of slots, and the shaft hole is located in one of the slots. The flow guiding assembly is mounted on the heat exchanger shell and communicates with the two groups of slots of the partition plate. A floating head is provided on the fixed tube sheet at the output end of the heat exchanger shell.

[0007] The drive assembly is mounted on the heat exchanger housing and is used to provide rotational power to the stationary tube sheet.

[0008] Furthermore, the drive assembly includes a support member disposed on the heat exchanger housing, a drive motor disposed on the support member, a transmission gear coaxially disposed at the output end of the drive motor, and an external gear ring coaxially disposed on the fixed tube plate at the input end, the transmission gear meshing with the external gear ring for transmission connection.

[0009] Preferably, the support is provided with an isolation element, and the transmission gear is located inside the isolation element.

[0010] Furthermore, multiple sets of support beams are equidistantly arranged on the two sets of fixed tube sheets.

[0011] Preferably, the flow guiding assembly includes an extension pipe and a conduction assembly. The extension pipe is coaxially disposed at the shaft hole of the pipe box. A first connecting pipe is rotatably disposed on the extension pipe. A drain pipe is disposed on the first connecting pipe. A first stabilizing member is disposed on the first connecting pipe. The first stabilizing member is disposed on the heat exchanger shell. The conduction assembly is disposed on the first stabilizing member.

[0012] Furthermore, the conductive component includes a second stabilizing member disposed on the first stabilizing member, a second connecting pipe disposed on the second stabilizing member, a water inlet pipe disposed on the second connecting pipe, a guide pipe rotatably disposed in the groove of the second connecting pipe, the guide pipe rotatably disposed inside the through groove of the first connecting pipe, and the other end of the guide pipe being disposed in the positioning hole of the partition plate.

[0013] Preferably, an auxiliary component is provided in the extension tube cavity, and a guide tube is provided on the auxiliary component.

[0014] Furthermore, the support assembly includes multiple sets of support seats disposed at the bottom end of the heat exchanger shell. Piston sliders are slidably disposed in two sets of symmetrically arranged adjustment holes on the support seats. Support feet are disposed on the piston sliders, and springs are disposed at the other end of the piston sliders. The springs are disposed on the adjustment assembly.

[0015] Preferably, the adjustment component includes an adjustment stud disposed in the threaded hole of the support base, the adjustment stud being slidably disposed on the spring, and the adjustment stud being provided with a polygonal adjustment hole.

[0016] Furthermore, an outer cover is installed at the outlet end of the heat exchanger shell via screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The symmetrical arrangement of multiple sets of mounting holes on the fixed tube sheet allows for uniform distribution of the heat exchange tube bundles, ensuring the uniformity of fluid flow within the heat exchanger and improving heat exchange efficiency. Through the design of the partition plate, the multiple sets of heat exchange tube bundles on the fixed tube sheet are divided at the input end, guiding the fluid flow direction. This design allows one side of the multiple sets of heat exchange tube bundles at both ends of the partition plate to be used for water inlet and the other side for water outlet. The flow guiding component guides the fluid inlet and outlet after heat exchange. The drive component enables the fixed tube sheet to obtain rotational power, driving the heat exchange tube bundles to rotate. The rotation design enhances the turbulence of the fluid outside the heat exchange tube bundle, further improving heat exchange efficiency. Simultaneously, the rotational motion helps remove deposits from the outer wall of the heat exchange tube bundle, reducing the likelihood of fouling and extending the equipment's lifespan. The floating head at the output end connects multiple sets of heat exchange tube bundles at both ends of the partition plate, forming a complete fluid return trajectory. It should be noted that this structure extends the fluid's transit time within the heat exchanger shell. The bolted connection between the fasteners and the tube box simplifies installation and disassembly, facilitating regular maintenance and cleaning, improving heat exchange efficiency, and reducing equipment energy consumption.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] like Figures 1 to 6 As shown, the shock-resistant and buffer-type tubular heat exchanger of this utility model includes:

[0027] The heat exchanger shell 1 and the flow guiding assembly are provided. The heat exchanger shell 1 is mounted on the support assembly. Fixed tube sheets 2 are rotatably mounted at both ends of the shaft cavity of the heat exchanger shell 1. Multiple sets of mounting holes are symmetrically arranged on the fixed tube sheets 2. Heat exchange tube bundles 3 are installed in the mounting holes arranged coaxially on the two sets of fixed tube sheets 2. A fixing member 4 is provided on the fixed tube sheet 2 at the input end of the heat exchanger shell 1. A tube box 5 is mounted on the fixing member 4 by bolts. A partition plate 6 is provided inside the tube box 5. The partition plate 6 is set on the fixed tube sheet 2 and divides the multiple sets of heat exchange tube bundles 3 symmetrically arranged on the fixed tube sheet 2 into two groups. A shaft hole is provided on the tube box 5. The partition plate 6 divides the inner cavity of the tube box 5 into two groups of slots, and the shaft hole is located in one of the slots. The flow guiding assembly is mounted on the heat exchanger shell 1 and communicates with the two groups of slots of the partition plate 6 respectively. A floating head 7 is provided on the fixed tube sheet 2 at the output end of the heat exchanger shell 1.

[0028] The drive assembly, mounted on the heat exchanger housing 1, provides rotational power to the fixed tube sheet 2. Multiple sets of symmetrically arranged mounting holes on the fixed tube sheet 2 ensure uniform distribution of the heat exchange tube bundles 3, guaranteeing uniform fluid flow within the heat exchanger and improving heat exchange efficiency. Through the design of the partition plate 6, the multiple sets of heat exchange tube bundles 3 on the fixed tube sheet 2 are divided at the inlet, guiding the fluid flow direction. This design allows one side of the multiple sets of heat exchange tube bundles 3 at both ends of the partition plate 6 to be used for water inlet and the other side for water outlet. The flow guiding assembly guides the fluid inflow and outflow after heat exchange. The drive assembly enables the fixed tube sheet 2 to obtain rotational power. The rotation of the heat exchange tube bundle 3 enhances the turbulence of the fluid outside the heat exchange tube bundle 3, further improving heat exchange efficiency. At the same time, the rotation helps to remove deposits on the outer wall of the heat exchange tube bundle 3, reducing the possibility of fouling and extending the service life of the equipment. The floating head 7 at the output end can connect multiple sets of heat exchange tube bundles 3 at both ends of the partition plate 6 to form a complete fluid return trajectory. It should be noted that this structure extends the fluid's passage time in the heat exchanger shell 1. The design of the fastener 4 connected to the tube box 5 by bolts simplifies the installation and disassembly process, facilitates regular maintenance and cleaning, improves heat exchange efficiency, and reduces equipment energy consumption.

[0029] like Figures 1 to 6As shown, in a preferred embodiment, the drive assembly includes a support member 8 mounted on the heat exchanger housing 1, a drive motor 9 mounted on the support member 8, a transmission gear 10 coaxially mounted on the output end of the drive motor 9, and an external gear ring 11 coaxially mounted on the fixed tube sheet 2 at the input end. The transmission gear 10 meshes with the external gear ring 11 for transmission. An isolation member 12 is mounted on the support member 8, and the transmission gear 10 is located inside the isolation member 12. Multiple sets of support beams 13 are equidistantly mounted on the two sets of fixed tube sheets 2. The drive motor 9 enables the fixed tube sheet 2 to obtain stable rotational power, thereby driving the heat exchange tube bundle 3 to rotate. This design enhances the turbulence of the fluid outside the heat exchange tube bundle 3, further improving heat exchange efficiency. The transmission gear 10 meshes with the external gear ring 11 on the fixed tube sheet 2, achieving a smooth and reliable transmission of driving force. The isolation member 12 places the transmission gear 10 inside, effectively preventing external impurities from entering the gear transmission system, reducing wear, and extending the service life of the gears. The multiple sets of support beams 13 equidistantly arranged on the two sets of fixed tube sheets 2 not only enhance the structural rigidity of the fixed tube sheets 2, but also ensure the stability of the heat exchange tube bundle 3 during rotation, avoiding deformation or vibration caused by rotation, and improving the operational stability and safety of the equipment.

[0030] like Figures 1 to 6 As shown, in a preferred embodiment, the flow guiding assembly includes an extension pipe 14 and a conduction assembly. The extension pipe 14 is coaxially disposed at the shaft hole of the tube box 5. A first connecting pipe 15 is rotatably disposed on the extension pipe 14. A drain pipe 16 is disposed on the first connecting pipe 15. A first stabilizing member 17 is disposed on the first connecting pipe 15. The first stabilizing member 17 is disposed on the heat exchanger shell 1. The conduction assembly is disposed on the first stabilizing member 17. The extension pipe 14 is coaxially disposed at the shaft hole of the tube box 5, so that the first connecting pipe 15 is rotatably connected to the tube box 5. The first stabilizing member 17 stably supports the first connecting pipe 15 on the heat exchanger shell 1. When the extension pipe 14 rotates with the fixed tube plate 2, the position and angle of the drain pipe 16 are fixed, and the normal flow of fluid is maintained. The drain pipe 16 is disposed on the first connecting pipe 15, which can smoothly discharge the heat-exchanged fluid from the heat exchanger shell 1 and facilitate connection with external equipment.

[0031] like Figures 1 to 6As shown, in a preferred embodiment, the conductive assembly includes a second stabilizing member 18 disposed on the first stabilizing member 17. A second connecting pipe 19 is disposed on the second stabilizing member 18, and a water inlet pipe 20 is disposed on the second connecting pipe 19. A guide pipe 21 is rotatably disposed within the cavity of the second connecting pipe 19, and the guide pipe 21 is rotatably disposed inside the through groove of the first connecting pipe 15. The other end of the guide pipe 21 is disposed in the positioning hole of the partition plate 6. An auxiliary member 22 is disposed in the through cavity of the extension pipe 14, and the guide pipe 21 is disposed on the auxiliary member 22. The second connecting pipe 19 is stably supported on the second stabilizing member 18 by the second stabilizing member 18. The second connecting pipe 19, disposed on the second stabilizing member 18 and connected to the water inlet pipe 20, allows the fluid to smoothly enter the heat exchange tube bundle and guide the flow. The guide tube 21 is rotatably disposed in the groove of the second connecting tube 19 and also rotatably disposed in the through groove of the first connecting tube 15. This design allows the guide tube 21 to rotate with the fixed tube sheet 2 when it rotates, ensuring smooth fluid flow inside the heat exchanger and maintaining the fixed position and angle of the guide tube 21. The other end of the guide tube 21 is disposed in the positioning hole of the partition plate 6. This design allows fluid to flow from the inlet pipe 20 into the heat exchange tube bundle 3. An auxiliary component 22 is disposed in the through cavity of the extension tube 14, and the guide tube 21 is disposed on the auxiliary component 22. This design not only enhances the support of the guide tube 21, but also ensures the stability of the guide tube 21 during rotation, avoiding bending or damage caused by external forces and extending the service life of the equipment.

[0032] like Figures 1 to 6 As shown, in a preferred embodiment, the support assembly includes multiple sets of support seats 23 disposed at the bottom of the heat exchanger shell 1. Piston sliders 24 are slidably disposed within two sets of symmetrically arranged adjustment holes on the support seats 23. Support feet 25 are disposed on the piston sliders 24, and a spring 26 is disposed at the other end of the piston sliders 24. The spring 26 is disposed on the adjustment assembly, which includes an adjustment stud 27 disposed within a threaded hole in the support seat 23. The adjustment stud 27 is slidably disposed on the spring 26 and has polygonal adjustment holes. The multiple sets of support seats 23 at the bottom of the heat exchanger shell 1 ensure sufficient support points during installation, improving the stability of the equipment. The polygonal adjustment holes on the adjustment stud 27 allow for precise adjustment using specialized tools. The spring 26 at the other end of the piston slider 24 absorbs and buffers vibrations from the ground, reducing vibrations during operation and improving the equipment's seismic resistance. The strength of the spring 26 is adjusted by rotating the adjustment stud 27.

[0033] like Figures 1 to 6As shown, as a preferred embodiment, an outer cover 28 is provided at the output end of the heat exchanger housing 1 by screws; the outer cover 28 is provided at the output end of the heat exchanger housing 1 by screws, which simplifies the installation and disassembly process of the equipment, and the floating head 7 is isolated by the outer cover 28, thereby improving the sealing and heat preservation.

[0034] like Figures 1 to 6 As shown, the preferred solution operates as follows:

[0035] The inlet pipe 20 introduces fluid into the heat exchanger shell 1. The fluid enters the second connecting pipe 19 through the inlet pipe 20 and enters the heat exchange tube bundle 3 through the guide pipe 21. The fluid flows inside the heat exchange tube bundle 3 and exchanges heat with another fluid outside the tubes. During this process, the drive assembly drives the fixed tube sheet 2 to rotate through the cooperation of the drive motor 9, the transmission gear 10 and the external gear ring 11, so that the heat exchange tube bundle 3 rotates inside the heat exchanger shell 1, which enhances the turbulence of the fluid outside the heat exchange tube bundle 3. The fluid after heat exchange enters the first connecting pipe 15 through the other side of the partition plate 6 and is discharged from the heat exchanger shell 1 through the drain pipe 16.

[0036] The shock-resistant buffer tubular heat exchanger of this utility model can be installed, connected, or set up using common mechanical methods. Any method that can achieve its beneficial effects can be implemented.
