Description

Technical Field

[0001] This utility model is a double-sided detachable tubular heat exchanger, belonging to the field of heat exchanger technology. Background Technology

[0002] Tubular heat exchangers, as core equipment for achieving heat exchange between fluids in industrial production, are widely used in chemical, power, and food processing industries. They achieve heat exchange through the counter-current flow of cold fluid inside the tube bundle and hot fluid on the shell side. The core requirements are to ensure heat exchange efficiency while facilitating regular cleaning of the tube bundle (to avoid scaling affecting heat transfer) and maintenance of the sealing structure (to prevent fluid leakage). Most existing tubular heat exchangers adopt a "single-sided detachable + single-sided fixed" structure (such as fixed tube sheet heat exchangers), that is, one end cap is detachable through a flange connection, while the other end tube sheet is welded and fixed to the shell.

[0003] Chinese patent CN221571187U proposes a double-sided detachable tubular heat exchanger. When an internal fault occurs, the device can be repaired by removing the fastening screws on both sides and then removing the first and second inspection covers, exposing the interior of the heat exchanger body for easy maintenance. However, the device actually requires a large number of screws for double-sided disassembly, which requires workers to unscrew each screw one by one, wasting considerable time and effort. There is an urgent need for a double-sided detachable tubular heat exchanger to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a double-sided detachable tubular heat exchanger to solve the problems mentioned in the background. This invention adopts a transmission-type multi-point snap-fit ​​and magnetic fixing structure, which enables the rapid installation or removal of the double-sided inspection cover of the tubular heat exchanger. In addition, the double sealing structure ensures its sealing performance during installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-sided detachable tubular heat exchanger, comprising a tubular heat exchanger body and detachable panels. The tubular heat exchanger body has longitudinally welded fixed panels on both its left and right sides. Each of the two fixed panels has a detachment slot in the middle of its side surface, and each of the two detachment slots has an annular slot. A sealing rubber ring is fixed inside each of the two annular slots. Two detachable panels are provided, each attached to the outside of one of the two fixed panels. Multiple side slots are provided at the front and rear ends of both the detachable panels and the two fixed panels. Each side slot has a strong magnet attached to it. Both of the two detachable panels have access covers extending through their outer sides. Each of the two access covers has annular grooves on their inner sides. Each of the two annular grooves has a lip seal attached to it. Metal slot plates are fitted at the connection between the two detachable panels and the upper ends of the two fixed panels. Two sets of bearing seats are longitudinally mounted on the upper ends of the two metal slot plates. A bidirectional threaded rod extends through between the two sets of bearing seats. Nut sleeves are installed at the front and rear ends of the two bidirectional threaded rods. Adjusting plates are fixedly fitted on the outside of the multiple nut sleeves. Multiple metal insert blocks are attached to the inner sides of the multiple adjusting plates.

[0006] Furthermore, the two inspection covers are respectively connected to the left and right ends of the tubular heat exchanger body, the two lip seals are respectively fitted together with two sealing rubber rings, and a partition plate is horizontally welded in the middle of the inside of the right inspection cover. The tubular heat exchanger body has a built-in medium conveying pipe, and a partition baffle is horizontally fixed on the right side of the inside of the medium conveying pipe, with the left end of the partition plate in close contact with the partition baffle.

[0007] Furthermore, the plurality of metal insert blocks are respectively inserted into the plurality of side slots, and the plurality of metal insert blocks are respectively attracted to the plurality of strong magnet pieces by magnetic attraction.

[0008] Furthermore, the upper and lower ends of the inspection cover on the right are respectively fitted with a medium outlet pipe and a medium inlet pipe.

[0009] Furthermore, a hexagonal weld ring is welded to the middle of the outer surface of each of the two bidirectional threaded rods.

[0010] Furthermore, two bearing seats are welded to the lower end of the tubular heat exchanger body, an outlet pipe is installed on the upper right side of the tubular heat exchanger body, and an inlet pipe is installed on the lower left side of the tubular heat exchanger body.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a double-sided detachable tubular heat exchanger. Because it incorporates a fixed panel, sealing rubber ring, strong magnetic sheet, easy-to-remove panel, lip seal ring, partition plate, metal groove plate, bearing seat, bidirectional threaded rod, hexagonal welded ring, adjusting plate, nut sleeve, and metal insert block, its structure is reasonable. It adopts a transmission-type multi-point snap-fit ​​and magnetic fixing structure, enabling rapid installation or removal of the double-sided inspection cover of the tubular heat exchanger. This saves time and effort during operation. Furthermore, the double sealing structure ensures a tight seal during installation, making it highly practical. Attached Figure Description

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a double-sided detachable tubular heat exchanger, including a tubular heat exchanger body 1 and detachable panels 10. Fixed panels 5 are longitudinally welded to both sides of the tubular heat exchanger body 1. A disassembly groove is formed in the middle of the side surface of each fixed panel 5, and an annular slot 6 is formed at each disassembly groove. A sealing rubber ring 7 is fixed inside each annular slot 6. Two detachable panels 10 are provided, each attached to the outside of the two fixed panels 5. Multiple side slots 8 are formed at the front and rear ends of both detachable panels 10 and the two fixed panels 5. Strong magnets 9 are adhered to the multiple side slots 8. Inspection covers 11 are provided through the outside of both detachable panels 10. Both inner sides are provided with annular grooves 12, and lip seals 13 are glued into both annular grooves 12. Metal slot plates 17 are clamped at the connection between the two detachable panels 10 and the upper ends of the two fixed panels 5. Two sets of bearing seats 18 are longitudinally installed on the upper ends of the two metal slot plates 17. A bidirectional threaded rod 19 is provided through the two sets of bearing seats 18. Nut sleeves 22 are installed at the front and rear ends of the two bidirectional threaded rods 19. Adjusting plates 21 are fixedly sleeved on the outside of the multiple nut sleeves 22. Multiple metal insert blocks 23 are glued to the inner sides of the multiple adjusting plates 21. This design solves the problem that the original device actually requires a large number of screws to achieve double-sided disassembly, and the workers need to unscrew the screws one by one during disassembly, which is a waste of working time and effort.

[0020] As the first embodiment of this utility model: two inspection covers 11 are respectively connected to the left and right ends of the tubular heat exchanger body 1. Two lip seals 13 are respectively fitted together with two sealing rubber rings 7. A partition plate 14 is horizontally welded in the middle of the inside of the right inspection cover 11. The tubular heat exchanger body 1 has a built-in medium conveying pipe, and a partition baffle is horizontally fixed on the right side of the inside of the medium conveying pipe. The left end of the partition plate 14 is in close contact with the partition baffle. By adding two lip seals 13 and fitting together with two sealing rubber rings 7, the sealing performance at the connection between the two inspection covers 11 and the left and right ends of the tubular heat exchanger body 1 can be improved. A medium outlet pipe 15 and a medium inlet pipe 16 are respectively installed through the upper and lower ends of the right inspection cover 11. The addition of the medium outlet pipe 15 and the medium inlet pipe 16 facilitates the addition of cooling medium to the medium conveying pipe through the medium outlet pipe 15. Then, through the separation of the partition plate 14, the medium discharged from the medium conveying pipe can be discharged through the medium outlet pipe 15. Multiple metal inserts 23 are inserted into multiple side slots 8, and each metal insert 23 is magnetically attracted to multiple strong magnets 9. This connection and fixation between the two detachable panels 10 and the two fixed panels 5 is achieved by inserting multiple metal inserts 23 into multiple side slots 8 and magnetically attracting multiple strong magnets 9. Each of the two bidirectional threaded rods 19 has a hexagonal welded ring 20 welded to its outer center. The hexagonal welded rings 20 facilitate external disassembly by using a wrench to turn the two bidirectional threaded rods 19. The front and rear threads of the two bidirectional threaded rods 19 rotate in opposite directions. Therefore, when the two bidirectional threaded rods 19 rotate clockwise, the nut sleeve 22 can drive multiple adjusting plates 21 to move in opposite directions; conversely, when the two bidirectional threaded rods 19 rotate counterclockwise, the nut sleeve 22 can drive multiple adjusting plates 21 to move in the opposite direction. Two bearing seats 2 are welded to the lower end of the tubular heat exchanger body 1. An outlet pipe 3 is installed on the upper right side of the tubular heat exchanger body 1, and an inlet pipe 4 is installed on the lower left side of the tubular heat exchanger body 1. The addition of the outlet pipe 3 and the inlet pipe 4 facilitates the introduction and discharge of heat exchange gas.

[0021] As a second embodiment of this utility model: When it is necessary to disassemble the inspection cover 11 to perform maintenance on the tubular heat exchanger body 1, use an external wrench to turn the hexagonal welded ring 20. The hexagonal welded ring 20 drives the bidirectional threaded rod 19 to rotate counterclockwise. At this time, it will adjust the two nut sleeves 22 to move in opposite directions outside the bidirectional threaded rod 19 through the thread principle. It will also drive the two adjusting plates 21 to move in opposite directions simultaneously until the multiple metal insert blocks 23 separate from the multiple strong magnet pieces 9. After the multiple metal insert blocks 23 are completely withdrawn from the multiple side slots 8, pull the metal slot plate 17 upward, and then pull the easy-to-disassemble panel 10 outward. The lip seal ring 13 separates from the sealing rubber ring 7, and the inspection cover 11 can be disassembled quickly and conveniently.
