Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of shell-and-tube graphite heat exchangers, specifically a shockproof and impact-resistant shell-and-tube graphite heat exchanger. Background Technology
[0002] Shell-and-tube graphite heat exchangers are heat exchangers whose heat transfer components are made of graphite. The graphite used to manufacture heat exchangers should be impermeable. Impermeable graphite and pressed impermeable graphite are commonly used. Shell-and-tube graphite heat exchangers have good corrosion resistance, are not prone to scaling on the heat transfer surface, and have good heat transfer performance. Due to their good thermal conductivity and corrosion resistance, shell-and-tube graphite heat exchangers are widely used in chemical, pharmaceutical and other industries.
[0003] For example, CN222514286U discloses a shell-and-tube graphite heat exchanger, which relates to the field of heat exchanger equipment technology. In this shell-and-tube graphite heat exchanger, when the cooling medium is input, it is connected to the dust collector sleeve via a locking seat. The dust collector sleeve and the inner wall of the filter box are in close contact, ensuring that the cooling medium passes through the filter plate for filtration. This facilitates the filtration and adsorption of various impurities in the cooling medium, preventing frictional damage to the surface of the graphite heat exchanger tubes and extending the service life of the shell-and-tube graphite heat exchanger. When the material to be cooled is input through the feed pipe, a hydraulic sensor monitors the hydraulic data in the pipe in real time, and the data is output to the terminal for statistical processing via an information transmission module. When the hydraulic sensor detects that the hydraulic pressure in the section is too high, an electrically controlled pressure-reducing valve is electrically connected to the hydraulic sensor to facilitate timely control of the valve to reduce the hydraulic pressure in the pipe, preventing high pressure from affecting the graphite heat exchanger tubes and thus protecting them.
[0004] While the aforementioned patent facilitates timely control of the electronically controlled pressure-reducing valve to lower the hydraulic pressure inside the tube and prevent high pressure from affecting the graphite heat exchange tube, thus protecting the graphite heat exchange tube, the prior art of this patent does not have a shock-resistant and impact-resistant structure on the outside of the shell-and-tube graphite heat exchanger. Therefore, its shock-resistant and impact-resistant performance is generally poor, reducing its practicality. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 The shockproof and impact-resistant tubular graphite heat exchanger in this embodiment includes a mounting plate 1 and a tubular graphite heat exchanger body 2. The upper surface of the mounting plate 1 is provided with four support rods 3, and the top of the four support rods 3 is provided with a protective component 4. The outer side of the tubular graphite heat exchanger body 2 is provided with a shock-absorbing component 5.
[0026] In this embodiment, mounting holes are provided at the four corners of the lower surface of the mounting plate 1, and four support rods 3 are distributed in a rectangular shape on the upper surface of the mounting plate 1.
[0027] It should be noted that the shell-and-tube graphite heat exchanger body 2 is existing technology, and its internal structure and working principle will not be described in detail.
[0028] Please see Figure 2 In this embodiment, the protective component 4 includes a rectangular ring 401 fixed to the top of four support rods 3. A first protective plate 402 is fixed on both the left and right sides of the rectangular ring 401. A first buffer layer 403 is provided on the opposite side of the first protective plate 402 on both the left and right sides. A second protective plate 404 is fixed on both the front and back sides of the rectangular ring 401. A second buffer layer 405 is fixed on the opposite side of the second protective plate 404 on both the front and back sides. The opposite side of the first protective plate 402 on both the left and right sides is in contact with the left and right sides of the second protective plate 404 on both the front and back sides. The first protective plate 402, the second protective plate 404 and the rectangular ring 401 are all made of metal.
[0029] Specifically, both the first buffer layer 403 and the second buffer layer 405 are rubber layers.
[0030] It should be noted that two first protective plates 402 and two second protective plates 404 surround the shell-and-tube graphite heat exchanger body 2 to form a protective cover, preventing external objects from directly impacting the shell-and-tube graphite heat exchanger body 2. When an external impact occurs, the protective plates first bear the impact force. The two first buffer layers 403 and two second buffer layers 405 are all made of rubber material, which can absorb and disperse the impact energy. When the protective plates are impacted, the buffer layers will deform, thereby reducing the intensity of the impact force transmitted to the shell-and-tube graphite heat exchanger body 2.
[0031] Please see Figures 3 to 4 In this embodiment, the shock absorption assembly 5 includes a fixing frame 501 that is fixed to the outside of the shell-and-tube graphite heat exchanger body 2 by bolts. Connecting rods 502 are fixed on both the left and right sides of the lower surface of the fixing frame 501. Circular grooves 503 are opened on both the left and right sides of the upper surface of the rectangular ring 401. Buffer rubber blocks 504 are fixed to the bottom walls of the inner cavities of the circular grooves 503 on both the left and right sides. Slide plates 505 are fixed to the upper surfaces of the buffer rubber blocks 504 on both the left and right sides. The slide plates 505 on both the left and right sides are slidably connected to the inside of the circular grooves 503 on both the left and right sides. The bottom ends of the connecting rods 502 on both the left and right sides are fixedly connected to the upper surfaces of the slide plates 505 on both the left and right sides. Limiting members are provided on the outer sides of the connecting rods 502 on both the left and right sides.
[0032] Specifically, the limiting component includes a slide cylinder 506 slidably connected to the outside of the connecting rods 502 on both the left and right sides. A connecting frame 507 is fixed on the opposite side of the slide cylinders 506 on both the left and right sides. The bottom ends of the connecting frames 507 on both the left and right sides are fixedly connected to the left and right sides of the upper surface of the rectangular ring 401. Two limiting rings 508 are fixed on the outside of the connecting rods 502 on both the left and right sides. The slide cylinder 506 is located between the opposite sides of the upper and lower limiting rings 508. The outer diameter of the slide plate 505 is adapted to the inner diameter of the circular groove 503. The slide plate 505 moves linearly up and down inside the circular groove 503. The circular grooves 503 on the left and right sides are symmetrically distributed on the left and right sides of the longitudinal central axis of the rectangular ring 401.
[0033] It should be noted that when the shell-and-tube graphite heat exchanger body 2 is subjected to vibration, the fixing frame 501 will transmit the vibration to the sliding plates 505 on the left and right sides through the connecting rods 502 on the left and right sides. The sliding plates 505 on the left and right sides move up and down within the circular grooves 503 on the left and right sides. At the same time, the buffer rubber blocks 504 on the left and right sides will deform to absorb the vibration energy, thereby reducing the impact of vibration on the shell-and-tube graphite heat exchanger body 2. The design of the limiting ring 508 and the sliding cylinder 506 ensures that the movement range of the connecting rod 502 is strictly limited, preventing damage to the buffer rubber block 504 or other structural problems due to excessive displacement.
[0034] The working principle of the above embodiments is as follows:
[0035] In use, two first protective plates 402 and two second protective plates 404 surround the body 2 of the shell-and-tube graphite heat exchanger, forming a protective shield to prevent external objects from directly impacting the body 2. When an external impact occurs, the protective plates first bear the impact force. The two first buffer layers 403 and two second buffer layers 405 are all made of rubber material, which can absorb and disperse the impact energy. When the protective plates are impacted, the buffer layers deform, thereby reducing the intensity of the impact force transmitted to the body 2 of the shell-and-tube graphite heat exchanger. When the heat exchanger body 2 is subjected to vibration, the fixed frame 501 will transmit the vibration to the sliding plates 505 on the left and right sides through the connecting rods 502 on the left and right sides. The sliding plates 505 on the left and right sides move up and down within the circular grooves 503 on the left and right sides. At the same time, the buffer rubber blocks 504 on the left and right sides will deform to absorb the vibration energy, thereby reducing the impact of vibration on the shell and tube graphite heat exchanger body 2. The design of the limiting ring 508 and the sliding cylinder 506 ensures that the movement range of the connecting rod 502 is strictly limited, preventing damage to the buffer rubber block 504 or other structural problems due to excessive displacement.
