Description

Technical Field

[0002] A heat exchanger is an energy-saving device that enables heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters of the process to meet the requirements of the process conditions. It is also one of the main devices for improving energy utilization efficiency.

[0003] Traditional heat exchangers used in nitrogen production typically rely heavily on bolts for component connections. The connection between the mounting base and the outer casing requires multiple bolts, which must be unscrewed one by one during disassembly, resulting in cumbersome, time-consuming, and labor-intensive operations. Furthermore, the nitrogen production process demands frequent use of the heat exchanger; due to the difficulty of installation and disassembly, maintenance, repair, or component replacement require significant manpower and time, leading to prolonged downtime and increased maintenance and production costs. To address the shortcomings of existing technologies, this invention provides a heat exchanger for nitrogen production to solve the aforementioned problems. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides a heat exchanger for nitrogen production, which solves the problem that traditional heat exchangers used for nitrogen production typically rely heavily on bolt fastening for component connections. The connection between the mounting base and the outer shell requires multiple bolts, which need to be unscrewed one by one during disassembly, making the operation cumbersome, time-consuming, and labor-intensive. Furthermore, the nitrogen production process requires frequent use of the heat exchanger, and due to the difficulty of installation and disassembly, maintenance, repair, or component replacement require a lot of manpower and time, resulting in long downtime and increased maintenance and production costs.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example 1: This utility model embodiment discloses a heat exchanger for nitrogen production, according to the attached... Figure 1-5 As shown, it includes a heat exchanger shell 1, a heat exchange cylinder 2, a mounting base 3, several sets of conduits 4, a clamping block 5, a positioning tube 6, and a locking unit 7;

[0035] The heat exchanger shell 1 serves as the main structure, and a heat exchange cylinder 2 is installed inside. The first inlet pipe 21 and the first outlet pipe 22 on the heat exchange cylinder 2 are used for the entry and exit of the cooling medium. The mounting base 3 is provided on the side of the heat exchanger shell 1 and is used to connect and support the conduit 4. The second inlet pipe 41 and the second outlet pipe 42 on the conduit 4 are also used for the entry and exit of the medium so as to exchange heat with the medium inside the heat exchange cylinder 2.

[0036] The locking block 5 is mounted on the mounting base 3, the positioning tube 6 is mounted on the heat exchanger housing 1 and engages with the locking block 5, and the locking unit 7 is mounted on the heat exchanger housing 1 to limit the locking block 5. The locking block 5 has a locking hole 51, and the locking unit 7 is mounted on the heat exchanger housing 1, including an adjusting block 71, a locking rod 72 and a double-acting screw 73.

[0037] The locking block 5 has a locking hole 51, and the locking unit 7 includes:

[0038] Adjusting block 71 is slidably connected to heat exchanger housing 1;

[0039] The locking rod 72 is mounted on the adjusting block 71 and is movably inserted into the locking hole 51;

[0040] The bidirectional screw 73 is rotatably connected to the heat exchanger housing 1 and threadedly connected to the adjusting block 71.

[0041] The heat exchanger housing 1 is provided with a guide rail frame 711 on its side, an adjusting block 71 is slidably connected to the guide rail frame 711, and a bidirectional screw 73 is rotatably connected to the guide rail frame 711.

[0042] The locking hole 51 on the locking block 5 is movably inserted into the locking rod 72 of the locking unit 7. The adjusting block 71 is slidably connected to the guide rail 711 on the heat exchanger housing 1. The bidirectional screw 73 is rotatably connected to the heat exchanger housing 1 and threadedly connected to the adjusting block 71. By rotating the bidirectional screw 73, the position of the adjusting block 71 can be adjusted, thereby causing the locking rod 72 to move in the locking hole 51, thereby locking and limiting the locking block 5, and thus fixing the mounting base 3 and the guide tube 4 on the heat exchanger housing 1.

[0043] The bidirectional screw 73 is equipped with a rotating handle 731. The rotating handle 731 makes it easier and less strenuous to rotate the bidirectional screw 73, thereby making it easier to operate the locking unit 7, ensuring that the heat exchanger housing 1 and the mounting base 3 are easy to assemble and disassemble, and making the heat exchanger easy to maintain.

[0044] The heat exchanger housing 1 is fixedly connected to both sides of the housing with mounting brackets 11. The mounting brackets 11 are provided with mounting holes. The mounting brackets 11 and the heat exchanger housing 1 are fixed together in the target position by bolts.

[0045] A condensate drain pipe 8 is fixedly connected to the bottom of the heat exchanger housing 1, and a rubber ring 31 is movably engaged between the mounting base 3 and the heat exchanger housing 1.

[0046] The heat exchanger shell 1, heat exchange cylinder 2, and positioning tube 6 are designed as a single piece, improving the overall integrity and stability of the structure. The condensate drain pipe 8 at the bottom of the heat exchanger shell 1 is used to drain condensate, preventing condensate buildup from affecting the heat exchange effect. The rubber ring 31 that is movably engaged between the mounting base 3 and the heat exchanger shell 1 provides a seal, preventing media leakage.

[0047] The operation steps are as follows:

[0048] The heat exchanger is fixed in a suitable position using the mounting bracket 11.

[0049] Install conduit 4 on mounting base 3, ensuring that the second inlet pipe 41 and the second outlet pipe 42 are correctly connected to the external pipeline.

[0050] Align the locking block 5 with the positioning tube 6, and lock the locking block 5 onto the positioning tube 6 using the locking unit 7.

[0051] Check the sealing of the rubber ring 31 to ensure a good seal between the mounting base 3 and the heat exchanger housing 1.

[0052] Open the inlet and outlet valves for nitrogen or cooling medium to begin the heat exchange operation in the nitrogen production process.

[0053] Regularly check the condensate drain pipe 8 to ensure that the condensate can be drained normally, and clean or maintain it as necessary.

[0054] When maintenance or replacement of conduit 4 is required, loosen locking unit 7, disassemble conduit 4 to perform the corresponding operation, and then reinstall and lock it after completion.

[0055] Regularly inspect and maintain the entire heat exchanger to ensure its normal operation.
