Description

Technical Field

[0001] This utility model relates to the field of aromatic solvent distillation technology, specifically to a high-boiling-point aromatic distillation heat exchanger. Background Technology

[0002] Aromatic solvent distillation technology separates aromatic solvents using distillation columns, extracting specific components by utilizing the differences in their boiling points. High-boiling-point aromatic distillation heat exchangers are used to process high-temperature, stable high-boiling-point aromatic substances. They effectively recover and transfer heat, reducing energy consumption while maintaining the system's thermal balance and ensuring stable operation of the distillation process.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most common heat exchangers are one-piece structures, which makes it inconvenient to disassemble, install, and clean the internal components. They usually require multiple bolts for fixing, which necessitates tedious and laborious bolt removal operations. This results in low disassembly and assembly efficiency and makes it impossible to clean and maintain the internal scale of the heat exchanger in a timely manner, thus reducing the efficiency of aromatic solvent distillation. Utility Model Content

[0005] The purpose of this invention is to provide a high-boiling-point aromatic distillation heat exchanger to solve the problem mentioned in the background art of inconvenient disassembly, assembly, internal cleaning and maintenance of the heat exchanger.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-boiling-point aromatic hydrocarbon distillation heat exchanger, comprising a base, a handle on one side of the base, a screw mounted on one side of the handle, a locking block threaded onto the surface of the screw, sliding grooves at both ends of the middle of the upper surface of the base, a slider slidably connected inside the sliding grooves, a locking groove on one side of the slider, a heat exchanger body mounted on the top of the slider, a feed inlet mounted on the top of one side of the heat exchanger body, a discharge outlet mounted on the top of the other side of the heat exchanger body, convex rings mounted on both sides of the heat exchanger body, a cover plate sleeved inside the convex rings, uprights mounted on both sides of the outer surface of the convex rings, a rod slidably connected to the top of the uprights, a limit ring mounted on the bottom end of the rod, a return spring sleeved on the end of the rod near the limit ring, and slots on both sides of one end of the cover plate.

[0007] More preferably, through grooves are provided on both sides of the convex ring, and the internal dimensions of the through grooves and slots are consistent with the external dimensions of the insertion rod.

[0008] More preferably, a handle is installed at the top of the insertion rod, and the insertion rod forms a lifting structure with the upright frame through the handle.

[0009] In a further preferred embodiment, the insertion rod forms a buffer structure with the upright frame via a return spring.

[0010] More preferably, the upper surface of the base has grooves at both ends away from the slide groove, and the two ends of the screw are rotatably mounted on both sides of the inner wall of the groove.

[0011] In a further preferred embodiment, the locking block forms a transmission structure with the screw and the throttle.

[0012] More preferably, a through groove is provided on one side of the slide, and the internal dimensions of the through groove and the card slot are consistent with the external dimensions of the card block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This heat exchanger allows for easy disassembly and assembly by rotating the handles on both sides of the base, which in turn rotates the screw. This screw drive then moves the locking block horizontally until it is embedded in the slot, facilitating the removal and assembly of the heat exchanger body. Furthermore, by pulling the handles on both sides of the protruding ring, the insertion rod can be disengaged from the slot. Pulling the handle on one side of the cover plate allows the cover plates 12 on both sides of the heat exchanger body to be removed, facilitating cleaning and maintenance of the heat exchanger's interior. This avoids cumbersome bolt removal and installation operations, improving the efficiency of heat exchanger disassembly and assembly, and making the interior of the heat exchanger easier to clean and maintain, thereby improving the efficiency of aromatic solvent distillation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a high-boiling-point aromatic hydrocarbon distillation heat exchanger, including a base 1, a handle 2 on one side of the base 1, a screw 3 installed on one side of the handle 2, a locking block 4 threadedly connected to the surface of the screw 3, a sliding groove 5 installed at both ends of the middle part of the upper surface of the base 1, a slider 6 slidably connected inside the sliding groove 5, a locking groove 7 opened on one side of the slider 6, a heat exchanger body 8 installed on the top of the slider 6, a feed inlet 9 installed at the top of one side of the heat exchanger body 8, a discharge outlet 10 installed at the top of the other side of the heat exchanger body 8, convex rings 11 installed on both sides of the heat exchanger body 8, a cover plate 12 sleeved inside the convex rings 11, uprights 13 installed on both sides of the outer surface of the convex rings 11, a rod 14 slidably connected to the top of the uprights 13, a limiting ring 15 installed at the bottom end of the rod 14, a return spring 16 sleeved on the end of the rod 14 near the limiting ring 15, and slots 17 opened on both sides of one end of the cover plate 12.

[0022] In this embodiment, as Figure 4 As shown, through slots are provided on both sides of the convex ring 11, and the internal dimensions of the through slots and the slot 17 are consistent with the external dimensions of the insert rod 14.

[0023] In this embodiment, as Figure 4 As shown, a handle is installed on the top of the insertion rod 14, and the insertion rod 14 forms a lifting structure with the stand 13 through the handle.

[0024] In this embodiment, as Figure 4 As shown, the insertion rod 14 forms a buffer structure with the upright frame 13 through the return spring 16.

[0025] In this embodiment, as Figure 2 As shown, grooves are provided at both ends of the upper surface of the base 1 away from the slide groove 5, and the two ends of the screw 3 are rotatably installed on both sides of the inner wall of the groove.

[0026] In this embodiment, as Figure 2 As shown, the locking block 4 forms a transmission structure with the screw 3 and the throttle 2.

[0027] In this embodiment, as Figure 2 As shown, a through groove is provided on one side of the slide 5, and the internal dimensions of the through groove and the slot 7 are consistent with the external dimensions of the block 4.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the high-boiling-point aromatics distillation heat exchanger operates as follows:

[0029] First, the operator uses the mounting slots at both ends of the base 1 to install the base 1 into the required working position. When installing the heat exchanger body 8, the sliders 6 at both ends of the bottom of the heat exchanger body 8 can be slid into the slide groove 5. Then, the handles 2 on both sides of the base 1 are rotated to drive the screw 3 to rotate. This, through the action of the threaded transmission, drives the locking block 4 to move horizontally until the locking block 4 passes through the through groove on one side of the slide groove 5 and is further embedded into the locking groove 7, thus completing the installation of the heat exchanger body 8. The same operation method can be used when the heat exchanger body 8 needs to be disassembled. When it is necessary to clean and maintain the inside of the heat exchanger body 8, the handles on both sides of the protruding ring 11 are pulled to drive the insertion rod 1. 4. Perform vertical displacement until the insertion rod 14 disengages from the slot 17. Then, pull the handle on one side of the cover plate 12 to remove the cover plates 12 on both sides of the heat exchanger body 8. This allows for convenient cleaning and maintenance of the heat exchanger body 8. After maintenance, pull the handle to disengage the insertion rod 14 from the through slot. Simultaneously, align the slots 17 on both sides of the cover plate 12 with the position of the insertion rod 14 and further insert the cover plate 12 into the protruding ring 11. Then, release the handle. Under the elastic force of the return spring 16, the limiting ring 15 will push the insertion rod 14 down and embed it into the slot 17. This facilitates convenient heat exchanger disassembly and maintenance, avoids tedious and laborious bolt removal operations, and improves the efficiency of aromatic solvent distillation.
