Description

Technical Field

[0001] This utility model relates to the technical field of heat exchangers, and specifically to an auxiliary splicing device. Background Technology

[0002] In the process of upgrading and transforming chemical plants, in order to improve the heat exchange efficiency of the original shell-and-tube heat exchangers, one or more other shell-and-tube heat exchangers are usually connected in series. This can reduce the damage to the original infrastructure, facilitate the control of upgrading and transformation costs, and further improve the space utilization of the chemical plant. For example, the utility model patent with authorization announcement number CN219474357U, entitled "A Shell-and-Tube Heat Exchanger Connected in Series," includes a top heat exchanger and a bottom heat exchanger, which are connected in series by a connecting pipe. The hot inlet pipe and the hot outlet pipe are connected by a hot flow channel; the cold outlet pipe and the cold inlet pipe are connected by a cold flow channel; the bottom of the top heat exchanger and the bottom heat exchanger are respectively provided with multiple condensate drain pipes; the top heat exchanger and the bottom heat exchanger are connected in series by a connecting pipe, which increases the time for the hot medium and the cold medium to flow in the hot flow channel and the cold flow channel respectively, thereby improving the heat exchange time.

[0003] In chemical plants, some existing small shell-and-tube heat exchangers are fixedly installed on the top floor. Due to the limited space on the top floor, the area around the existing small shell-and-tube heat exchangers is already filled with other equipment. Therefore, it is usually necessary to manually lift another small shell-and-tube heat exchanger and suspend it in the air until it is aligned with and connected to the various inlets and outlets of the existing small shell-and-tube heat exchanger before letting go. This process is quite labor-intensive. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem of the high labor intensity associated with manually lifting and adjusting the orientation of newly added small shell-and-tube heat exchangers, this invention provides an auxiliary splicing device that can reduce labor intensity.

[0025] It should be noted that the auxiliary splicing device described in this utility model is used in, but not limited to, shell and tube heat exchangers. For ease of explanation, this utility model only uses the application of an auxiliary splicing device in a shell and tube heat exchanger as an example. The principle of the auxiliary splicing device applied to other types of equipment is essentially the same as that applied to a shell and tube heat exchanger, and will not be described in detail here.

[0026] Please see Figure 1 - Figure 5 ,in Figure 1 This is a schematic diagram of an auxiliary splicing device according to an embodiment of the present invention. The auxiliary splicing device includes a fixed plate 1, a lifting component 2, and a support component 3. The lifting component 2 includes a jack 21, a first mounting plate 22, and a second mounting plate 23. The first mounting plate 22 and the second mounting plate 23 are respectively fixedly connected to the top and bottom ends of the jack 21. The second mounting plate 23 is detachably connected to the fixed plate 1. The support component 3 includes an arc-shaped plate 31 and a connecting plate 32. The convex curved surface of the arc-shaped plate 31 is fixedly connected to the top surface of the connecting plate 32, and the bottom surface of the connecting plate 32 is detachably connected to the first mounting plate 22.

[0027] In this embodiment, the setting of the fixing plate 1 and the connecting plate 32 makes the lifting component 2 easy to disassemble, which in turn makes it easier for workers to carry. Furthermore, the setting of the lifting component 2 allows the arc plate 31 to support the newly added small shell-and-tube heat exchanger to the required height according to different site conditions. The whole process does not require manual lifting of the newly added small shell-and-tube heat exchanger until it is fixedly connected to the original small shell-and-tube heat exchanger before letting go, which effectively reduces labor intensity.

[0028] In one embodiment, the fixed plate 1, the lifting component 2, and the support component 3 are all arranged in pairs.

[0029] In this embodiment, the distance between the two fixed plates 1 is determined according to the length of the shell-and-tube heat exchanger superimposed on top, and then, with the help of two lifting components 2 and two supporting components 3, the shell-and-tube heat exchanger superimposed on top is supported more stably.

[0030] In one embodiment, the concave surface of the arc plate 31 is provided with a plurality of receiving holes 311, and a universal ball 33 is connected inside the receiving hole 311.

[0031] In one embodiment, the depth of the receiving hole 311 is smaller than the height of the omnidirectional ball 33.

[0032] In this embodiment, by avoiding direct contact between the shell-and-tube heat exchanger superimposed on top and the concave curved surface of the arc plate 31, the friction of the shell-and-tube heat exchanger superimposed on top during the orientation adjustment process is reduced. Furthermore, by having the shell-and-tube heat exchanger superimposed on top contact with each universal ball 33, it is easier for the operator to adjust the orientation of the shell-and-tube heat exchanger superimposed on top, making it smoother for the operator to connect the upper and lower shell-and-tube heat exchangers.

[0033] In one embodiment, each receiving hole 311 is evenly distributed along the arcuate direction of the arcuate plate 31.

[0034] In this embodiment, the stability of the shell-and-tube heat exchanger superimposed on top is further improved during the orientation adjustment process.

[0035] In one embodiment, the omnidirectional ball 33 includes a base 331 and a ball 332, the ball 332 being rotatably connected to the top of the base 331, and the bottom of the base 331 being fixedly fitted into the receiving hole 311.

[0036] In this embodiment, the base 331 is welded into the receiving hole 311. The rotation function of the ball bearing 332 reduces the friction of the shell-and-tube heat exchanger superimposed on it during the orientation adjustment process. The universal ball 33 is prior art and will not be described in detail.

[0037] In one embodiment, the first mounting plate 22 has a plurality of first through holes 221, and the connecting plate 32 has a plurality of first connecting holes 321, with each first through hole 221 corresponding to each first connecting hole 321.

[0038] In this embodiment, the first mounting plate 22 and the connecting plate 32 are fixedly connected by bolts passing through the first through hole 221 and the first connecting hole 321 in sequence.

[0039] In one embodiment, the second mounting plate 23 has a plurality of second through holes 231, and the fixing plate 1 has a plurality of second connecting holes 11, with each second through hole 231 corresponding to each second connecting hole 11.

[0040] In this embodiment, the second mounting plate 23 and the fixing plate 1 are fixedly connected by bolts passing through the second through hole 231 and the second connecting hole 11 in sequence.

[0041] In one embodiment, the area below the second connecting hole 11 is hollowed out.

[0042] In this embodiment, the installation of the bolt is facilitated, and space is provided to accommodate the nut in the bolt.

[0043] In one embodiment, the bottom surface of the fixing plate 1 is arc-shaped.

[0044] In this embodiment, in order to facilitate the connection between the fixing plate 1 and the outer wall of the shell-and-tube heat exchanger below, the bottom surface of the fixing plate 1 is arc-shaped and adapted to the outer wall of the shell-and-tube heat exchanger below. The bottom surface of the fixing plate 1 and the outer wall of the shell-and-tube heat exchanger below are fixedly connected by welding.

[0045] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0046] First, based on the length of the newly added small shell-and-tube heat exchanger, the spacing between the two fixing plates 1 is determined and welded to the top of the existing small shell-and-tube heat exchanger. Then, bolts are sequentially passed through the second through hole 231 and the second connecting hole 11, so that the second mounting plate 23 is fixedly connected to the fixing plate 1. Next, bolts are sequentially passed through the first connecting hole 321 and the first mounting hole, so that the first mounting plate 22 is fixedly connected to the connecting plate 32. Next, the newly added small shell-and-tube heat exchanger is moved onto the arc-shaped plate 31, and each universal ball 33 is connected to the newly added small shell-and-tube heat exchanger. The surfaces are in contact; then, using jack 21, the newly added small shell-and-tube heat exchanger is raised to a suitable height, and using the low resistance of ball bearings 332, the newly added small shell-and-tube heat exchanger is pushed or rotated to align and seal with the inlet and outlet of the original small shell-and-tube heat exchanger; finally, after the two small shell-and-tube heat exchangers are installed, the lifting assembly 2 and the support assembly 3 can be removed. The whole process does not require manual lifting of the newly added small shell-and-tube heat exchanger until it is fixedly connected with the original small shell-and-tube heat exchanger, which effectively reduces labor intensity.
