Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of heat exchanger network technology, and more specifically, to a heat exchanger network structure. Background Technology

[0002] A heat pipe heat exchanger is a high-efficiency heat exchange device consisting of a shell, heat pipes, and baffles. It transfers heat by circulating the working medium through a phase change between the evaporation and condensation sections. It has advantages such as high heat transfer efficiency and compact structure. There are many types of heat pipe heat exchangers, and they are widely used in many fields.

[0003] In carbon black production, heat pipe heat exchangers can be used to recover waste heat from the reaction, transferring the heat from the high-temperature flue gas generated during carbon black production to other processes or media that require heating. This improves energy efficiency, reduces production costs, helps control reaction temperature, makes the carbon black production process more stable, and enhances the quality and performance of carbon black products.

[0004] In heat pipe heat exchangers, the positioning and support of the heat exchange tube bundle are generally achieved using positioning plates. Holes are made in the positioning plates so that the heat exchange tubes can pass through them, thereby supporting the heat exchange tube bundle. However, in actual use, due to the high temperature inside the heat pipe heat exchanger, the positioning plates are easily deformed by prolonged exposure to high temperatures, which can affect the positioning and support of the heat exchange tube bundle. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a heat exchanger network structure, which solves the technical problem in the prior art that the positioning plate is exposed to a high temperature environment for a long time, which can easily cause the positioning plate to deform and thus affect the positioning and support of the heat exchanger tube bundle.

[0018] The drive screw is rotatably connected to one side of the pressure rod, and the fixed block has a screw hole, in which the drive screw is threaded.

[0019] The hexagonal block is fixedly connected to one end of the drive screw.

[0020] Furthermore, the reinforcing structure includes: a reinforcing tube and a connecting plate;

[0021] The reinforcing tubes are provided in multiple forms, and all of the reinforcing tubes are arranged on one side of the pressure rod;

[0031] 2. In this disclosure, by creating a chamfer on the positioning hole, the inner wall of the positioning hole becomes smoother, which can effectively remove burrs at the edge of the positioning hole, allowing the heat exchange tube to pass through the positioning hole more smoothly.

[0039] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0040] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0042] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-4As shown, a heat exchanger network structure according to an embodiment of the present disclosure is illustrated, including a positioning plate 1 with multiple positioning holes, and further including: reinforcing ribs 2, chamfers 3, pressure rods 4, and reinforcing structures. There are two reinforcing ribs 2, both of which are arranged in a ring shape and are respectively fixedly connected to the two sides of the positioning plate 1. Chamfers 3 are provided at the inner wall edges of the multiple positioning holes. The reinforcing ribs 2 can effectively prevent deformation at the edges of the positioning plate 1. By providing chamfers 3 on the positioning holes, the inner walls of the positioning holes are made smoother, which can effectively remove burrs at the edges of the positioning holes, allowing the heat exchanger tubes to pass through the positioning holes more smoothly.

[0046] Two pressure rods 4 are provided, and the two pressure rods 4 are respectively set on both sides of the positioning plate 1 through two clamping mechanisms. The clamping mechanism includes: a fixed plate 5, a support rod 6, a slider 7 and a drive assembly. There are two fixed plates 5, and both fixed plates 5 are fixedly connected to one side of the positioning plate 1. The support rod 6 is fixedly connected to one end of the two fixed plates 5. Both fixed plates 5 are provided with sliding grooves. The two sliders 7 are slidably connected in the two sliding grooves. The pressure rod 4 is fixedly connected between the two sliders 7. The drive assembly is set on the support rod 6 and is used to drive the pressure rod 4 to move. The drive assembly includes: a fixed block 8, a drive screw 9 and a hexagonal block 10. A rotating block 14 is fixedly connected to the pressure rod 4. One end of the drive screw 9 is rotatably connected to the rotating block 14, which can increase the stability of the drive screw 9 when rotating. The fixed block 8 is fixedly connected to the support rod 6. The drive screw 9 is rotatably connected to one side of the pressure rod 4. The fixed block 8 is provided with a screw hole. The drive screw 9 is threaded into the screw hole. The hexagonal block 10 is fixedly connected to one end of the drive screw 9.

[0047] The operator can rotate the hexagonal block 10. When the hexagonal block 10 rotates, it drives the drive screw 9 to rotate, which in turn drives the pressure rod 4 to press against the positioning plate 1. The two pressure rods 4 press against the two sides of the positioning plate 1, thereby increasing the stability of the positioning plate 1 and reducing the deformation of the positioning plate 1.

[0048] Two reinforcing structures are fixedly connected to each of the two pressure rods 4 to limit the positioning plate 1. The reinforcing structures include: reinforcing tubes 11 and connecting plates 12. Both the pressure rods 4 and the reinforcing tubes 11 are in contact with the surface of the positioning plate 1 to press the positioning plate 1. A stabilizing rod 15 is fixedly connected between each pair of adjacent connecting plates 12. The pressure rods 4 and the stabilizing rods 15 are both set between each pair of adjacent positioning holes. The connection of the stabilizing rods 15 increases the stability between the multiple reinforcing tubes 11. Furthermore, the fact that the pressure rods 4 and the stabilizing rods 15 are both set between each pair of adjacent positioning holes makes it less likely to obstruct the replacement. The heat pipe passes through the positioning hole, and the reinforcing tube 11 is the same as its corresponding positioning hole, which allows the heat exchange tube to pass through the positioning hole smoothly. The two reinforcing tubes 11 near the top and the two reinforcing tubes 11 near the bottom are all provided with screw holes, and fixing bolts 13 are threaded into the screw holes. After the heat exchange tube passes through the reinforcing tube 11, the fixing bolts 13 are tightened to abut against the heat exchange slide tube, thereby also positioning the positioning plate 1. There are multiple reinforcing tubes 11, and multiple reinforcing tubes 11 are all set on one side of the pressure rod 4. A connecting plate 12 is fixedly connected between each pair of longitudinally connected reinforcing tubes 11.

[0049] When the pressure rod 4 moves, it drives multiple reinforcing tubes 11 to press against the positioning plate 1, and clamps the heat exchange tubes passing through the reinforcing tubes 11 by fixing bolts 13, thereby further reducing the deformation of the positioning plate 1.

[0050] Working principle: After the heat exchange tubes pass through the positioning holes, part of the heat exchange tubes pass through the reinforcing tubes 11. Then, the operator rotates the hexagonal block 10. When the hexagonal block 10 rotates, it drives the drive screw 9 to rotate, which in turn drives the pressure rod 4 to press against the positioning plate 1. When the pressure rod 4 moves, the slider 7 moves in the groove, thereby increasing the stability of the pressure rod 4. When the two pressure rods 4 press the positioning plate 1 tightly, multiple reinforcing tubes 11 also abut against the positioning plate 1. Then, the operator twists the fixing bolts 13 to clamp the heat exchange tubes passing through the reinforcing tubes 11, thereby further reducing the deformation of the positioning plate 1.
