Description

Technical Field

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It plays an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. A spiral plate heat exchanger consists of two parallel metal plates rolled into two spiral channels, through which hot and cold fluids exchange heat through the spiral plate walls.

[0003] Most spiral plate heat exchangers consist of two parallel metal plates rolled into two spiral cavities. Hot and cold fluids exchange heat through the spiral plate walls. However, most spiral plate heat exchangers experience shaking during operation, which affects their efficiency, leads to wear and damage between components, increases maintenance costs, and shortens the equipment's lifespan. Therefore, it is necessary to improve the existing technology to solve these problems. Utility Model Content

The described embodiments are only some embodiments of the present utility model, 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.

[0022] Reference Figures 1-4A spiral plate heat exchanger for preventing swaying includes a base 1, a shell 6 slidably connected inside the base 1, an annular reinforcing ring 3 on the outer wall of the shell 6, multiple longitudinal support ribs 2 welded to the bottom of the annular reinforcing ring 3, one end of each longitudinal support rib 2 being fixed to the base 1, and two oblique support ribs 12 welded between adjacent longitudinal support ribs 2. A fixing assembly for fixing the shell 6 is provided on the outer wall of the annular reinforcing ring 3. A spiral metal plate 20 is welded inside the shell 6, with its bottom and top fixed to the bottom and top inner walls of the shell 6, respectively. A spiral cavity 18 is formed inside the spiral metal plate 20. A first feed pipe 5 and a second feed pipe 8 are welded to the top of the shell 6, with the second feed pipe 8 passing through the shell 6 and communicating with the spiral cavity 18. The top of the body 6 is welded with a first discharge pipe 7 and a second discharge pipe 9, and the second discharge pipe 9 passes through the shell 6 and is connected to the spiral cavity 18. In use, the shell 6 is placed in the base 1, so that the annular reinforcing ring 3, the longitudinal support rib 2 and the oblique support rib 12 are in contact with the shell 6, so that the fixing component fixes the shell 6. The base 1 provides support points, and the annular reinforcing ring 3, the longitudinal support rib 2 and the oblique support rib 12 enhance the structural stability and pressure bearing capacity of the shell 6 from the circumferential, longitudinal and oblique aspects, respectively. The fixing component plays the final fixing role to prevent the shell 6 from shifting, thereby reducing the shaking during use, reducing the impact on the working efficiency of the heat exchanger, reducing the wear and damage between components, reducing maintenance costs and increasing the service life of the equipment.

[0023] The fixing assembly includes multiple fixing rods 4, all of which are fixedly connected to the outside of the annular reinforcing ring 3. A ring 11 is slidably connected between the multiple fixing rods 4, and the ring 11 is slidably connected to the housing 6. Multiple fixing blocks 15 are fixedly connected to the top of the ring 11. A movable block 17 is rotatably connected to one end of each of the multiple fixing blocks 15. A buckle 16 is fixedly connected to one side of the multiple fixing blocks 15 and the movable block 17. The movable block 17 can be fixed to the fixing block 15 through the buckle 16. In use, the movable block 17 can be fixed to the fixing block 15, so that the movable block 17 is in close contact with the top of the housing 6, thereby fixing the housing 6.

[0024] In this invention, multiple rubber protrusions 14 are bonded to the inner circumference of the annular reinforcing ring 3 and the base 1, enabling the housing 6 to contact the annular reinforcing ring 3 within the base 1, increasing friction with the housing 6 and enhancing the stability of the device during use. Multiple honeycomb plates 19 are welded to the gaps between the spiral cavity 18 and the spiral metal plate 20, dispersing the impact force of the fluid as it passes through the honeycomb plates 19. Multiple support frames 21 are bolted to the top of the housing 6, and the first discharge pipe 7 and the second discharge pipe 9 are bolted to the support frames 21, reducing the generation and propagation of vibration during liquid transfer, protecting the discharge pipes from damage due to vibration during use, extending service life, and increasing the stability of the equipment. Multiple mounting seats 13 are welded to the outer side of the base 1, and multiple mounting holes are provided on the upper surface of each mounting seat 13, allowing the base 1 to be mounted on the platform, achieving a rigid connection between the base 1 and the platform.

[0025] Working principle: When heat exchange is required, the shell 6 is placed inside the base 1, so that the annular reinforcing ring 3, longitudinal support rib 2, and oblique support rib 12 are in close contact with the shell 6. At this time, the fixed block 15 and the movable block 17 are fixed together by the buckle 16, so that the movable block 17 is in close contact with the top of the shell 6. Then, hot fluid is added to the first feed pipe 5 and cold fluid is added to the second feed pipe 8, so that the cold fluid fills the spiral cavity 18 and the hot fluid fills the shell 6. Since the shell 6 is provided with a spiral metal plate 20, the first discharge pipe 7 is connected to the water pump to extract the hot fluid. At this time, the hot fluid flows along the spiral channel formed between the shell 6 and the spiral metal plate 20. Through the high thermal conductivity of the metal plate, the hot fluid exchanges heat with the cold fluid in the spiral cavity in the narrow channel, so that the shell 6 is fixed with the annular reinforcing ring 3 and the base 1, reducing the shaking during use, reducing the impact on the working efficiency of the heat exchanger, reducing wear and damage between components, reducing maintenance costs, and increasing the service life of the equipment.

[0026] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
