Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically a tubular heat exchanger with vibration damping function. Background Technology

[0002] Shell-and-tube heat exchangers, also known as tubular heat exchangers, are indirect heat exchangers that use the walls of tube bundles enclosed in a shell as the heat transfer surface. These heat exchangers are simple in structure, low in cost, have a wide flow cross-section, and are easy to clean for scale buildup; however, they have a low heat transfer coefficient and require a large footprint. They can be manufactured using various structural materials (mainly metals) and can be used under high temperature and high pressure, making them the most widely used type. Shell-and-tube heat exchangers include several types such as fixed tube sheet steam-water heat exchangers, shell-and-tube heat exchangers with expansion joints, floating head steam-water heat exchangers, U-shaped shell-and-tube heat exchangers, corrugated shell-and-tube heat exchangers, and segmented water-water heat exchangers. The main control parameters of shell-and-tube heat exchangers are heating area, hot water flow rate, heat transfer capacity, and heat medium parameters.

[0003] Patent publication number CN212778818U discloses a double-helix baffle heat exchanger. This utility model includes a shell, a first tube sheet and a second tube sheet fixedly connected to both sides of the shell, a first spiral plate and a second spiral plate fixedly connected to the inner wall of the shell, upper fixing rings provided on both sides of the top of the shell, and lower fixing rings provided on both sides of the bottom of the shell. Fixing bolts are provided on the upper and lower fixing rings, and a shock-absorbing device is fixedly connected to the bottom of the lower fixing ring. By setting the first and second spiral plates, a double spiral flow path is formed inside the shell, which can effectively reduce the flow velocity of the liquid in the shell, thereby reducing the vibration generated during liquid flow and improving the heat exchange efficiency of the liquid. The vibration damping device can further reduce the vibration generated by the equipment during operation. Patent publication number CN219656699U discloses a vibration damping bracket for a heat exchanger. This utility model includes a base and a fixing mechanism. The number of bases is two, and a fixing seat is bolted to the top of the base. This utility model installs spring ribs between the fixing seat and the support seat. With the use of a damper, the spring ribs can buffer the vibration potential energy transmitted from the support seat, and the damper can absorb and dissipate the vibration potential energy, thereby achieving the purpose of vibration damping and protecting the heat exchanger.

[0004] The aforementioned patent can buffer the heat exchanger body and reduce the flow velocity of the liquid in the shell to reduce the vibration generated during liquid flow. However, it still has the following shortcomings: in the structural design of the heat exchanger, the inlet and outlet are not linked with the baffle plate. This means that the baffle plate cannot make corresponding adjustments to adapt to changes in the flow velocity of the liquid, which affects the realization of the vibration reduction effect and also restricts the optimization of the heat exchanger performance to a certain extent. Summary of the Invention

[0005] The purpose of this invention is to provide a tubular heat exchanger with vibration damping function, which aims to solve the problem in the prior art that the baffles cannot be adjusted according to different liquid flow velocities, thus affecting the vibration damping effect.

When the fan-shaped ring rotates, it can drive the gear ring to rotate.

[0011] Preferably, the mid-section drive assembly includes a mid-section gear fixedly mounted on the first crossbar, a second rack fixedly mounted on the outer side of the sector ring and meshing with the mid-section gear, and a third rack fixedly connected to the inner sidewall of the sector ring and drivingly connected to the gear ring.

[0013] Preferably, the discharge drive assembly includes a primary ring plate, a secondary ring plate corresponding to the primary ring plate, and a rotatable tertiary rotating ring disposed between the primary and secondary ring plates. The diameter of the tertiary rotating ring is larger than the diameter of the primary and secondary ring plates, and the diameters of the primary and secondary ring plates are the same as those of the hot fluid outlet. Several discharge rotating rods are hinged to the three-stage rotating ring, and the discharge rotating rods are hinged to the second rotating plate. The first-stage ring plate is fixedly provided with a discharge fixing ring on the side facing the second-stage ring plate, and the second rotating plate is rotatably mounted on the discharge fixing ring via a rotating shaft; The three-stage rotating ring has several sets of open-ended arc-shaped discharge holes. Several short discharge rods are fixed between the first-stage ring plate and the second-stage ring plate, and each short discharge rod is slidably inserted into the arc-shaped discharge hole.

[0014] Preferably, a sixth toothed ring is fixedly provided on the outer peripheral side of the three-stage rotating ring, and a second transmission assembly that meshes with the sixth toothed ring is provided at the lower part of the housing, and the second transmission assembly is connected to the first crossbar for transmission.

[0015] Preferably, the second transmission assembly includes a sixth gear meshing with a sixth gear ring and a second vertical rod fixedly connected to the sixth gear; The second vertical rod passes through the housing and is fixedly connected to the second universal joint.

The discharge main bevel gear and the discharge secondary bevel gear mesh with each other.

[0016] The beneficial effects are as follows: 1. The orifice diameters of the hot fluid inlet and outlet of the heat exchanger can be adjusted through the feed adjustment components and discharge adjustment components. When the orifice diameter is adjusted, the flow velocity and pressure of the hot fluid will change, which will affect the flow state and pressure distribution of the hot fluid, and thus affect the vibration characteristics of the heat exchanger. In addition, orifice diameter adjustment can also change the flow direction and velocity distribution of the hot fluid, thereby reducing eddies and turbulence in the hot fluid flow process, further reducing the generation of vibration and noise, and thus effectively reducing the vibration and noise of the heat exchanger, improving its working efficiency and stability.

[0017] 2. When the sector ring and gear ring move under the action of the intermediate drive assembly, they can adjust the orifice diameter on the baffle plate. This changes the flow path and velocity of the fluid, thereby reducing the impact force of the fluid on the heat exchanger and achieving a vibration reduction effect. Specifically, when the hot fluid passes through the baffle plate, adjusting the orifice diameter makes the fluid flow smoother, reducing the generation of turbulence and eddies, thus reducing the impact force of the hot fluid on the heat exchanger and reducing vibration. In addition, adjusting the orifice diameter can also change the velocity distribution of the hot fluid, making the residence time of the fluid in the heat exchanger more uniform, improving heat exchange efficiency, and also reducing vibration.

[0018] 3. When the feed adjustment assembly adjusts the orifice diameter of the hot fluid inlet, it can also adjust the orifice diameter on the baffle plate and the orifice diameter of the hot fluid outlet. This creates a coordinated adjustment between the hot fluid inlet, outlet, and ventilation holes on the baffle plate. This adjustment optimizes the flow state of the hot fluid, making its flow within the heat exchanger smoother. When the inlet orifice diameter and the baffle plate orifice diameter are properly matched and adjusted, equipment vibration caused by uneven heat flow or turbulent vortices can be avoided. Furthermore, the coordinated orifice diameter adjustment reduces the impact force of the fluid on the equipment structure, preventing resonance caused by the impact force. This improves the overall operational stability of the heat exchanger and reduces noise, component wear, and potential safety hazards caused by vibration. Attached Figure Description

Detailed Implementation

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1-14 As shown, a tubular heat exchanger with vibration damping function is mainly used to adjust the aperture of the hot fluid inlet 3, hot fluid outlet 4 and the ventilation hole 6 on the baffle plate 103 in a coordinated manner, so as to reduce the impact force of the fluid on the equipment structure, avoid the resonance phenomenon caused by the impact force, thereby improving the overall stability of the operation of the heat exchanger 1 and reducing noise, component wear and potential safety hazards caused by vibration.

[0023] like Figure 1 and Figure 2As shown, the heat exchanger 1 includes a shell 101, tube boxes 102 installed at both ends of the shell 101, and multiple sets of baffles 103 fixed inside the shell 101. Ventilation holes 6 are provided on the baffles 103. A hot fluid inlet 3 communicating with the interior of the shell 101 is provided on the upper side of the upper and lower shells 101. A hot fluid outlet 4 communicating with the interior of the shell 101 is provided on the lower side of the shell 101 away from the hot fluid inlet 3. A cold fluid inlet 2 communicating with the tube box 102 is provided at the top of the tube box 102 near the hot fluid outlet 4. A cold fluid outlet 5 communicating with the tube box 102 is provided at the bottom of the tube box 102 near the hot fluid outlet 4.

[0024] In this embodiment, tube sheets are fixedly provided at both ends of the shell 101, and several sets of heat exchange tubes are fixedly provided between the two tube sheets. The heat exchange tubes are all fixedly connected to the baffle plate 103. A baffle plate is fixedly provided inside the tube box 102 equipped with the cold fluid inlet 2, so that the cold fluid enters the upper area formed by the tube box 102 and the baffle plate through the cold fluid inlet 2. Then the cold fluid flows to the other tube box 102 through the upper heat exchange tube, and then flows to the lower area formed by the tube box 102 and the baffle plate through the lower heat exchange tube. Finally, it is discharged from the cold fluid outlet 5. At this time, hot fluid is added from the hot fluid inlet 3, so that the hot fluid is distributed in the area between the two tube sheets and flows in a wave shape under the action of the baffle plate 103. Finally, it is discharged from the hot fluid outlet 4.

[0025] In this embodiment, the tubular heat exchanger with shock absorption function includes an adjustment mechanism installed in the heat exchanger 1. In this embodiment, the structure and principle of the heat exchanger 1 are existing technologies and will not be described in detail here.

[0026] like Figure 1 and Figure 2 As shown, the adjustment mechanism includes a feed adjustment component on the hot fluid inlet 3, a discharge adjustment component on the hot fluid outlet 4, and a mid-section adjustment component on the baffle plate 103. The feed adjustment component can adjust the orifice diameter of the hot fluid inlet 3, the discharge adjustment component can adjust the orifice diameter of the hot fluid outlet 4, and the mid-section adjustment component can adjust the orifice diameter of the ventilation hole 6 on the baffle plate 103, so as to reduce the impact of hot airflow on the equipment and thus reduce vibration.

[0027] like Figure 2 , Figure 3 and Figures 6-9 As shown, the feed adjustment assembly includes several sets of first rotating plates 7 and a feed drive assembly capable of driving the first rotating plates 7 to rotate. When the several sets of first rotating plates 7 rotate, the size of the hot fluid inlet 3 can be adjusted. The operator manually operates the feed drive assembly to rotate, so that the feed drive assembly drives the first rotating plates 7 to rotate, thereby achieving the purpose of adjusting the size of the hot fluid inlet 3 by blocking the size of the first rotating plates 7.

[0028] In this embodiment, a feed protection shell that can protect the feed drive assembly is fixedly provided on the housing 101.

[0029] Specifically, the feed drive assembly includes an upper ring plate 1001, a lower ring plate 1002 corresponding to the upper ring plate 1001, and an intermediate rotating ring 1003 rotatably disposed between the upper ring plate 1001 and the lower ring plate 1002. The diameter of the intermediate rotating ring 1003 is larger than the diameters of the upper ring plate 1001 and the lower ring plate 1002. The larger diameter of the intermediate rotating ring 1003 facilitates operation by the operator. The upper ring plate 1001 and the lower ring plate 1002 have the same diameter as the hot fluid inlet 3. The upper ring plate 1001 is connected to the connecting flange of the hot fluid inlet 3, and the lower ring plate 1002 is fixedly connected to the pipe opening of the hot fluid inlet 3.

[0030] Several feeding rotating rods 11 are hinged to the intermediate rotating ring 1003, and each feeding rotating rod 11 is hinged to the first rotating plate 7. A feeding fixing ring 12 is fixedly provided on the side of the lower ring plate 1002 facing the upper ring plate 1001. The first rotating plate 7 is rotatably mounted on the feeding fixing ring 12 through the first rotating shaft. When the intermediate rotating ring 1003 rotates, it can drive the feeding rotating rods 11 to rotate, so that the feeding rotating rods 11 drive the first rotating plate 7 to rotate around the first rotating shaft, so as to realize the closing and unfolding of multiple first rotating plates 7.

[0031] The intermediate rotating ring 1003 has several sets of vertically and vertically open feed arc-shaped holes 14. Several feed short rods 13 are fixed between the upper ring plate 1001 and the lower ring plate 1002. Each feed short rod 13 is slidably inserted into the feed arc-shaped hole 14. When the intermediate rotating ring 1003 rotates, the feed short rods 13 can move along the feed arc-shaped hole 14, thereby limiting the rotation angle of the intermediate rotating ring 1003, so as to achieve the complete closing and complete opening of the first rotating plate 7.

[0032] like Figure 8 and Figure 9 As shown, a first toothed ring 15 is fixedly provided on the outer peripheral side of the intermediate rotating ring 1003. A first transmission component that meshes with the first toothed ring 15 is provided on the housing 101. The first transmission component is connected to the intermediate drive component. The first toothed ring 15 can be used by the operator to make the ring swing. When the intermediate rotating ring 1003 rotates, the first toothed ring 15 on the intermediate rotating ring 1003 can also drive the first transmission component to rotate, thereby driving the intermediate drive component to rotate. This is used to adjust the size of the ventilation hole 6 by linking the baffle 8 on the deflector plate 103.

[0033] Specifically, the first transmission assembly includes a first gear 1601 meshing with a first gear ring 15, a first vertical rod 1602 fixedly connected to the first gear 1601, and a first horizontal rod 1603 transmittedly connected to the middle drive assembly. When the first gear 1601 rotates under the action of the first gear ring 15, the first gear 1601 can drive the first vertical rod 1602 to rotate. The first vertical rod 1602 passes through the housing 101 and is fixedly connected to a first universal joint. The other end of the first universal joint is fixedly connected to... When the first vertical rod 1602 rotates, the feeding connecting rod 19 can be driven to rotate through the first universal joint. The other end of the feeding connecting rod 19 is fixedly connected to the main feeding bevel gear 17. The end of the first horizontal rod 1603 near the first vertical rod 1602 is fixedly provided with the secondary feeding bevel gear 18. When the feeding connecting rod 19 rotates, it can drive the main feeding bevel gear 17 to rotate. Since the main feeding bevel gear 17 and the secondary feeding bevel gear 18 mesh with each other, they can drive the first horizontal rod 1603 to rotate.

[0034] In this embodiment, the first crossbar 1603 is located on the front side of the housing 101. This arrangement can not only move the baffle 8 located on the upper baffle 103 inside the housing 101, but also move the baffle 8 on the lower baffle 103 inside the housing 101, making the linkage more convenient.

[0035] like Figures 3-5 As shown, the mid-section adjustment assembly includes a baffle 8 rotatably mounted on the baffle plate 103 and a mid-section drive assembly capable of driving the baffle 8 to rotate about the central axis of the housing 101. The mid-section drive assembly is connected to the first crossbar 1603. The baffle 8 has a baffle hole 25 corresponding to the ventilation hole 6, so that when the first rotating plate 7 adjusts the size of the hot fluid inlet 3, the baffle 8 can adjust the size of the ventilation hole 6 on the baffle plate 103.

[0036] Specifically, the baffle 8 includes a sector ring 801 rotatably mounted on the baffle plate 103 and a gear ring 802 rotatably mounted on the baffle plate 103. The baffle plate 103 has a limiting groove for the sector ring 801 and the gear ring 802 to rotate. When the sector ring 801 rotates, it can drive the gear ring 802 to rotate. In this embodiment, when the sector ring 801 and the gear ring 802 rotate, they can rotate along the limiting groove. On the one hand, it can limit the sector ring 801 and the gear ring 802. On the other hand, it can support the sector ring 801 and the gear ring 802 to prevent them from tilting.

[0037] The mid-section drive assembly includes a mid-section gear 2001 fixedly mounted on the first crossbar 1603, a second rack 2002 fixedly mounted on the outer side of the sector ring 801 and meshing with the mid-section gear 2001, and a third rack 2003 fixedly connected to the inner sidewall of the sector ring 801 and drivingly connected to the gear ring 802. When the first crossbar 1603 rotates, it can drive the mid-section gear 2001 on the first crossbar 1603 to rotate. Since the mid-section gear 2001 meshes with the second rack 2002, it can drive the sector ring 801 to rotate. When the sector ring 801 rotates, it can drive the third rack 2003 to rotate together.

[0038] A fourth gear 23 is rotatably mounted on the baffle plate 103, meshing with the third rack 2003 on the sector ring 801. A fifth gear 24 is rotatably mounted on the baffle plate 103, meshing with the fourth gear 23. The fifth gear 24 meshes with the gear ring 802. When the third rack 2003 rotates, it can drive the fourth gear 23 to rotate. Since the fourth gear 23 and the fifth gear 24 mesh with each other, they can drive the fifth gear 24 to rotate. The fifth gear 24 then drives the gear ring 802 to rotate, so that both the sector ring 801 and the gear ring 802 rotate.

[0039] In this embodiment, the shielding holes 25 are respectively opened on the fan-shaped ring 801 and the gear ring 802. When the shielding holes 25 on the fan-shaped ring 801 and the gear ring 802 correspond to the ventilation holes 6 on the baffle plate 103, the ventilation holes 6 are fully open. When the fan-shaped ring 801 and the gear ring 802 rotate and block the ventilation holes 6, the ventilation holes 6 are adjusted to become smaller, so as to reduce the impact force of the hot fluid. In this embodiment, since the teeth on the fan-shaped ring 801 and the teeth on the gear ring 802 are distributed differently, the rotation angle of the fan-shaped ring 801 and the rotation angle of the gear ring 802 are also different, so that the fan-shaped ring 801 and the gear ring 802 can block the corresponding ventilation holes 6.

[0040] like Figures 12-14 As shown, the discharge adjustment assembly includes several sets of second rotating plates 9 and a discharge drive assembly capable of driving the second rotating plates 9 to rotate. The discharge drive assembly is connected to the middle section drive assembly so that when the baffle 8 adjusts the size of the ventilation hole 6 on the baffle 103, the second rotating plate 9 can adjust the size of the hot fluid outlet 4.

[0041] Specifically, the discharge drive assembly includes a primary ring plate 2601, a secondary ring plate 2602 corresponding to the primary ring plate 2601, and a tertiary rotating ring 2603 rotatably positioned between the primary ring plate 2601 and the secondary ring plate 2602. The primary ring plate 2601 is fixedly connected to the flange of the hot fluid outlet 4, while the upper end of the secondary ring plate 2602 is fixedly connected to the pipe opening of the hot fluid outlet 4. The diameter of the tertiary rotating ring 2603 is larger than the diameters of the primary ring plate 2601 and the secondary ring plate 2602, and the diameters of the primary ring plate 2601 and the secondary ring plate 2602 are the same as those of the hot fluid outlet 4. Several discharge rotating rods 27 are hinged to the moving ring 2603, and the discharge rotating rods 27 are hinged to the second rotating plate 9. A discharge fixing ring 28 is fixed on the side of the first ring plate 2601 facing the second ring plate 2602. The second rotating plate 9 is rotatably mounted on the discharge fixing ring 28 through the second rotating shaft. When the third rotating ring 2603 rotates, it can drive the discharge rotating rods 27 to rotate, so that the discharge rotating rods 27 drive the second rotating plate 9 to rotate around the second rotating shaft, so that the second rotating plate 9 opens or closes. The structure and principle of the second rotating plate 9 are the same as those of the first rotating plate 7.

[0042] The three-stage rotating ring 2603 has several sets of vertically and vertically permeable arc-shaped discharge holes 29. Several discharge short rods 30 are fixed between the first-stage ring plate 2601 and the second-stage ring plate 2602. Each discharge short rod 30 is slidably inserted into the discharge arc-shaped hole 29. When the three-stage rotating ring 2603 rotates, the discharge short rods 30 can move along the discharge arc-shaped hole 29, thereby limiting the rotation angle of the three-stage rotating ring 2603, so as to achieve the complete closing and complete opening of the second rotating plate 9.

[0043] A sixth toothed ring 31 is fixedly provided on the outer peripheral side of the third-stage rotating ring 2603. A second transmission component that meshes with the sixth toothed ring 31 is provided at the lower part of the housing 101. The second transmission component is connected to the first crossbar 1603. When the sixth gear 3201 rotates, it can drive the sixth toothed ring 31 to rotate, thereby driving the third-stage rotating ring 2603 to rotate.

[0044] The second transmission assembly includes a sixth gear 3201 meshing with the sixth gear ring 31 and a second vertical rod 3202 fixedly connected to the sixth gear 3201. When the second vertical rod 3202 rotates, it can drive the sixth gear 3201 to rotate, causing the sixth gear ring 31 to rotate. The second vertical rod 3202 passes through the housing 101 and is fixedly connected to a second universal joint. The other end of the first universal joint is fixedly connected to a discharge connecting rod 33. When the discharge connecting rod 33 rotates, it drives the second vertical rod 3202 to rotate through the second universal joint. The other end of the discharge connecting rod 33 is fixedly connected to a discharge main bevel gear 34. A discharge secondary bevel gear 35 is fixedly provided on the side of the first horizontal rod 1603 away from the hot fluid inlet 3. When the first horizontal rod 1603 rotates, it can drive the discharge secondary bevel gear 35 to rotate. Since the discharge main bevel gear 34 and the discharge secondary bevel gear 35 mesh with each other, they can drive the discharge connecting rod 33 to rotate.

[0045] Working principle: Cold fluid is heated into heat exchanger 1 through cold fluid inlet 2, and hot fluid is added into heat exchanger 1 through hot fluid inlet 3. When the hot fluid is added into heat exchanger 1, the operator can rotate the intermediate rotating ring 1003. When the intermediate rotating ring 1003 rotates, it drives the feed rotating rod 11 to rotate, causing the feed rotating rod 11 to drive the first rotating plate 7 to rotate around the first rotating shaft. When the intermediate rotating ring 1003 rotates, it can cause the feed short rod 13 to move along the feed arc-shaped hole 14, thereby limiting the rotation angle of the intermediate rotating ring 1003 to achieve the complete closing and opening of the first rotating plate 7. When the intermediate rotating ring 1003 rotates, it drives the first gear ring 15 to rotate, causing the first gear 1601 to rotate under the action of the first gear ring 15. The first gear 1601 then drives the first vertical rod 1602 to rotate. When the first vertical rod 1602 rotates, it drives the feeding connecting rod 19 to rotate via the first universal joint. When the feeding connecting rod 19 rotates, it drives the feeding main bevel gear 17 to rotate. Since the feeding main bevel gear 17 and the feeding secondary bevel gear 18 mesh with each other, they drive the first horizontal rod 1603 to rotate. When the first horizontal rod 1603 rotates, it drives the intermediate gear 2001 on the first horizontal rod 1603 to rotate. Gear 2001 meshes with the second rack 2002, thus driving the sector ring 801 to rotate. When the sector ring 801 rotates, it drives the third rack 2003 to rotate as well. The third rack 2003 then drives the fourth gear 23 to rotate. Since the fourth gear 23 meshes with the fifth gear 24, it drives the fifth gear 24 to rotate. The fifth gear 24 then drives the gear ring 802 to rotate, thus achieving rotation of both the sector ring 801 and the gear ring 802. This allows the sector ring 801 and the gear ring 802 to adjust and block the corresponding ventilation holes 6. When the first crossbar 1603 rotates, it also drives the discharge auxiliary bevel gear 35 to rotate. Since the main bevel gear 34 and the secondary bevel gear 35 mesh with each other, they can drive the discharge connecting rod 33 to rotate. When the discharge connecting rod 33 rotates, it drives the second vertical rod 3202 to rotate through the second universal joint. When the second vertical rod 3202 rotates, it can drive the sixth gear 3201 to rotate, causing the sixth gear ring 31 to rotate. When the sixth gear 3201 rotates, it can drive the sixth gear ring 31 to rotate, which in turn drives the third-stage rotating ring 2603 to rotate. When the third-stage rotating ring 2603 rotates, it can drive the discharge rotating rod 27 to rotate, causing the discharge rotating rod 27 to drive the second rotating plate 9 to rotate around the second rotating shaft, thus opening or closing the second rotating plate 9.
