Description

Technical Field

[0001] This invention relates to the field of plate heat exchanger technology, specifically a high heat transfer plate heat exchanger for pressure isolation stations. Background Technology

[0002] Pressure stabilization stations are crucial facilities in centralized heating systems, primarily used to regulate the pressure and temperature of the heating network, ensuring the safe, stable, and efficient operation of the system. The plate heat exchangers used in these stations are highly efficient and compact heat exchange devices, mainly used to transfer heat from the primary network (high temperature and high pressure) to the secondary network (user end), while simultaneously isolating the pressure systems on both sides.

[0003] A search revealed a Chinese patent with application number "CN202020010159.2", which specifically describes a plate heat exchanger with microchannels to improve heat transfer efficiency. The plate includes a front shell, end plates, plates, and a mounting bracket. The end plates are attached to the left side of the front shell, and positioning plates are engaged on both the upper and lower sides of the front shell. A limiting hole extends through the right side of the positioning plate, and a pressing plate is engaged inside the limiting hole. The mounting bracket is fixed to the left end of the positioning plate by a fixing bolt. A protrusion, integral with the plates, is provided on the outer side of the drainage channel. A first flow and a second fluid flow within the drainage channel. The front shell and rear shell are fixed together by screws.

[0004] In the aforementioned patent, the plate heat exchanger is connected to the conveying channel via a flange for convenient heat exchange of the fluid. However, when the pressure of the conveyed fluid fluctuates or becomes unstable, the connecting flange may loosen over time, causing the conveyed fluid to leak out. This can affect the heat exchange efficiency of the plate heat exchanger. Furthermore, when the heat of the conveyed fluid is high, the gasket in the flange may harden and crack, making the fluid prone to leakage. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides the following technical solutions:

[0031] Example 1

[0032] Please see Figures 1-3 , Figures 6-8A high-heat-transfer plate heat exchanger for a pressure relief station includes a front clamping plate 1 and a rear clamping plate 3. A heat exchange plate 2 and a connecting screw 4 are disposed between the front clamping plate 1 and the rear clamping plate 3. Multiple heat exchange plates 2 are provided. A fixing frame 5 is provided on the rear side of the rear clamping plate 3. Multiple connecting pipes 6 are fixedly connected to the front side of the front clamping plate 1, and connecting flanges 7 are fixedly connected to the front ends of the connecting pipes 6. A stabilizing unit 8 is provided on the front side of the front clamping plate 1. The heat exchange plate 2 includes a flow distribution zone 21, multiple inlets and outlets 23, and a heat exchange zone 22. The stabilizing unit 8 includes a stabilizing component 84, which is used to stabilize the connecting pipes. The Lan 7 plate is stable and prevents fluid leakage. The heat exchange zone 22 uses different combinations of "V" shaped corrugated angles (L / M / H plates) to improve the heat exchange effect per unit area, adjust fluid resistance, and the whole unit is assembled with different mixing ratios according to different working conditions to achieve the best flow and heat exchange effect (large angle H plates are assembled at the front, mixed M plates are assembled in the middle, and 20% L plates are assembled at the end to balance flow and pressure drop). Each plate covers three different groove depth specifications: shallow groove, deep groove, and ultra-deep groove. After assembly, they form plate heat exchangers with narrow gap, wide gap, and ultra-wide gap, respectively.

[0033] The stabilizing component 84 includes a moving ring 841, which is located outside the connecting pipe 6. A protective cylinder 842 is fixedly connected to the front end of the moving ring 841. A connecting block 843 is fixedly connected between the two protective cylinders 842. A moving plate 844 is fixedly connected to the front side of the connecting block 843. A threaded rod 845 is rotatably connected to the front side of the front clamping plate 1. The threaded rod 845 is threadedly connected to the moving plate 844. A rotating cap 846 is fixedly connected to the front end of the threaded rod 845. When using the plate heat exchanger, the external pipe is connected to the connecting pipe 6 through the connecting flange 7. Then, the rotating cap 846 is rotated, which drives the threaded rod 845 to rotate. The threaded rod 845 drives the moving plate 844 to move forward. The moving plate 844 drives the connecting block 843 to move. The connecting block 843 drives the protective cylinder 842 to move forward, so that the protective cylinder 842 can protect the connecting flange 7.

[0034] Inside the protective cylinder 842, and on both the upper and lower sides of the connecting flange 7, are fixed plates 8421. Lifting grooves 8422 are provided on the outer sides of the upper and lower fixed plates 8421. A control block 8423 is slidably connected to the inner side of the lifting groove 8422. A U-shaped block 8424 is fixedly connected to the front side of the control block 8423. A mounting block 8425 is fixedly connected to the front side of the U-shaped block 8424. A stabilizing plate 8426 is fixedly connected to the side of the mounting block 8425 closest to the connecting flange 7. A sliding rod 8428 is fixedly connected to the left side of the control block 8423. A mounting plate 8431 is fixedly connected to the front side of the front clamping plate 1. The front end of the mounting plate 8431 passes through the inner side of the protective cylinder 842 and is fixedly connected to a limit block 8429. An inclined section is provided on the outer side of the limit block 8429. The groove 8430 and the sliding rod 8428 are slidably connected to the inclined groove 8430. When the protective cylinder 842 moves forward, the protective cylinder 842 drives the fixed plate 8421 to move, the fixed plate 8421 drives the stabilizing plate 8426 to move forward, and at the same time controls the sliding rod 8428 to move forward. Under the action of the inclined groove 8430, the control block 8423 is lowered, the control block 8423 drives the U-shaped block 8424 to move, the U-shaped block 8424 drives the mounting block 8425 to move, and the mounting block 8425 drives the stabilizing plate 8426 to move. Since the inclined grooves 8430 on the upper and lower sides are symmetrically distributed, it is convenient for the stabilizing plates 8426 on the upper and lower sides to move closer to the connecting flange 7, so that the stabilizing plates 8426 on the upper and lower sides can clamp and limit the connecting flange 7, increase the stability of the connection of the connecting flange 7, and prevent loosening.

[0035] An arc-shaped airbag 8427 is fixedly connected to the side of the stabilizing plate 8426 near the connecting flange 7. An air cylinder 8418 is fixedly connected to the front side of the front clamping plate 1. A piston ring 8419 is provided on the inner side of the air cylinder 8418. A moving rod 8420 is fixedly connected between the piston ring 8419 and the moving ring 841. A connecting hose 8432 is fixedly connected between the air cylinder 8418 and the arc-shaped airbag 8427. When the stabilizing plate 8426 limits the connecting flange 7, the moving ring 841 drives the moving rod 8420 to move. The moving rod 8420 drives the piston ring 8419 to move. The piston ring 8419 pushes out the gas in the air cylinder 8418 and fills the arc-shaped airbag 8427 with gas through the connecting hose 8432, causing the arc-shaped airbag 8427 to expand, which facilitates the sealing operation of the outside of the connecting flange 7.

[0036] Example 2

[0037] Based on Example 1, such as Figures 4-7As shown, two fixing plates 847 are fixedly connected to both the upper and lower sides of the protective cylinder 842. Sliding grooves 848 are provided on the outer sides of both fixing plates 847. Lifting blocks 849 are slidably connected to the inner sides of the sliding grooves 848. Mounting blocks 8410 are fixedly connected to the front side of the lifting blocks 849. A support plate 8411 is fixedly connected to the outer side of the mounting blocks 8410. Rotating blocks 8412 are fixedly connected to the rear sides of both the upper and lower lifting blocks 849. An inclined plate 8413 is rotatably connected to the outer side of the rotating blocks 8412. A rotating block 8414 is rotatably connected to the outer side of the rear end of the inclined plate 8413. A fixing block 8415 is fixedly connected to the rear side of the rotating block 8414. A fixing ring 8416 is fixedly connected to the outer side of the fixing block 8415. A connecting rod 8417 is fixedly connected between the ring 8416 and the front clamping plate 1. The support plate 8411 has an arc-shaped structure, and the upper and lower inclined plates 8413 are symmetrically distributed. The support plate 8411 is located in front of the protective cylinder 842. When the protective cylinder 842 moves, the inclined plate 8413 is controlled to rotate under the action of the fixing block 8415, the fixing ring 8416 and the connecting rod 8417. The inclined plate 8413 drives the lifting block 849 to descend. The lifting block 849 drives the installation block 8410 to move. The installation block 8410 drives the support plate 8411 to move, so that the support plate 8411 moves forward and approaches the external pipe, which facilitates the support plates 8411 on both sides to support the external pipe and increases the stability of the external pipe connection.

[0038] A cooling assembly 85 is provided on the front side of the moving ring 841. The cooling assembly 85 includes a fixing rod 851, which is fixedly connected to the front side of the moving ring 841. An annular pipe 852 is fixedly connected to the front end of the fixing rod 851. Multiple branch pipes 853 are fixedly connected to the front side of the annular pipe 852. A nozzle 854 is fixedly connected to the front end of the branch pipe 853. A diversion pipe 83 is fixedly connected between two annular pipes 852. A cold air blower 81 is fixedly connected to the front side of the front clamping plate 1. A conveying pipe 82 is fixedly connected between the cold air blower 81 and the diversion pipe 83. When heat exchange is performed, the cold air blower 81 is started. Under the action of the conveying pipe 82 and the diversion pipe 83, cold air is introduced into the annular pipe 852 and then through the branch pipe 853 and the nozzle 854. This allows multiple nozzles 854 to spray cold air onto the connecting flange 7, which facilitates cooling of the connecting flange 7 and prevents the connecting flange 7 from becoming too hot, which could affect the sealing of the connecting flange 7.

[0039] Working principle: In use, the operator first connects the external pipe to the connecting pipe 6 through the connecting flange 7, then performs heat exchange on the fluid through the heat exchange plate 2. Next, the rotating cap 846 is rotated, which drives the threaded rod 845 to rotate. Under the action of the moving plate 844 and the connecting block 843, the protective cylinder 842 is moved forward to protect the connecting flange 7. Simultaneously, under the action of the fixing block 8415, the fixing ring 8416, and the connecting rod 8417, the inclined plate 8413 is rotated. Under the action of the fixing plate 847, the lifting block 849, and the mounting block 8410, the upper and lower support plates 8411 are opened and closed relative to each other, facilitating the support plates 8411 to support and clamp the external pipe. When the protective cylinder 842 moves the stabilizing plate 8426, under the action of the control block 8423, the slide rod 8428, and the inclined groove 8430, the stabilizing plates 8426 on both sides are controlled to move closer to the connecting flange 7, which facilitates the limiting of the connecting flange 7 and increases the stability of the connecting flange 7 installation. At the same time, the moving ring 841 moves the piston ring 8419, which, under the action of the connecting hose 8432, causes the arc-shaped airbag 8427 to expand, increasing the sealing of the connecting flange 7 installation and making it less likely for fluid to leak from the connecting flange 7 during heat exchange. During the heat exchange process, the cooling fan 81 is started, and multiple nozzles 854 spray cold air onto the connecting flange 7 to facilitate the cooling of the connecting flange 7 and prevent high temperature from affecting the sealing of the connecting flange 7 connection.
