Description

Technical Field

[0001] This utility model relates to the field of heat exchanger installation technology, and in particular to a vertical heat exchanger support. Background Technology

[0002] A vertical heat exchanger is a device with a vertically installed shell that achieves heat exchange between hot and cold fluids through indirect heat transfer. Its core function is to utilize two fluids with different temperatures flowing in a vertically arranged shell and tube bundle, transferring heat through the tube walls or shell walls to meet the heating, cooling, condensation, or evaporation requirements of the process.

[0003] When installing and using vertical heat exchangers, a fixed support frame is usually used to position the heat exchanger, and flange plates are used to connect and fix the pipes. However, existing vertical heat exchanger support frames are usually welded from a single piece of steel. This results in a fixed installation height for the vertical heat exchanger, making it difficult to make fine adjustments to the installation height according to the layout of the connecting pipes, so that the interface end of the vertical heat exchanger corresponds to the layout of the pipes. This has certain defects. Utility Model Content

[0015] 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.

[0016] Example 1: This utility model provides the following... Figures 1-3 The vertical heat exchanger support shown includes a base plate 1, a fixing collar 2, a support assembly 3, and a drive assembly 4. The fixing collar 2 is located on the top of the base plate 1 and is used to connect and fix the vertical heat exchanger. The fixing collar 2 is fixedly connected to the flange collar on the vertical heat exchanger by bolts, which is prior art and will not be described in detail here. The support assembly 3 is installed between the base plate 1 and the fixing collar 2. The drive assembly 4 is installed on the support assembly 3 and is used to drive the support assembly 3 to adjust the height of the fixing collar 2, thereby adjusting the installation height of the vertical heat exchanger so that the interface end of the vertical heat exchanger can be connected to the arranged pipes.

[0017] Furthermore, the support assembly 3 includes a fixed housing 31, a connecting housing 32, a support column 33, an adjusting screw 34, and a threaded groove. The fixed housing 31 is fixedly connected to the top of the base plate 1, the connecting housing 32 is fixedly connected to the top of the fixed housing 31, and the support column 33 is fixedly connected to the bottom of the fixed collar 2. The outer wall of the support column 33 is slidably sleeved with the fixed housing 31. The fixed housing 31, the connecting housing 32, the support column 33, and the adjusting screw 34 are all made of steel, and their strength is sufficient to support the weight of the vertical heat exchanger. The outer wall of the adjusting screw 34 is rotatably disposed inside the connecting housing 32. A limiting collar 35 is fixedly sleeved on the bottom of the outer wall of the adjusting screw 34. The limiting collar 35 is located inside the connecting housing 32 and the fixed housing 31 respectively. That is, a through hole corresponding to the adjusting screw 34 is opened between the fixed housing 31 and the connecting housing 32. Under the action of the limiting collar 35, the stability of the rotational connection between the adjusting screw 34 and the fixed housing 31 and the connecting housing 32 can be guaranteed. A threaded groove is opened at the bottom of the support column 33. The outer wall of the adjusting screw 34 is threadedly sleeved with the inner cavity of the threaded groove. Thus, by rotating the adjusting screw 34, the height of the support column 33 inside the connecting housing 32 can be adjusted.

[0018] Furthermore, the support assembly 3 also includes a locking bolt 36, a bearing collar 37, and a support spring 38. The outer wall of the locking bolt 36 is threaded to the connecting housing 32, and one end of the locking bolt 36 is pressed against the support column 33. After the position of the support column 33 is adjusted, the locking bolt 36 can lock the support column 33, thereby ensuring the stability of the vertical heat exchanger installation. The bearing collar 37 is fixedly sleeved inside the connecting housing 32, and the support spring 38 is sleeved inside the connecting housing 32. The support spring 38 is located between the bearing collar 37 and the support column 33. The support spring 38 can balance part of the weight of the support column 33 and the vertical heat exchanger, thereby facilitating the adjustment screw 34 to adjust the height of the vertical heat exchanger.

[0019] Furthermore, the drive assembly 4 includes a drive shaft 41, a second reversing gear 43, and a braking unit. The outer wall of the drive shaft 41 is rotatably connected to the fixed housing 31. During installation, a bearing acting on the drive shaft 41 can be installed inside the fixed housing 31 to ensure the stability of the drive shaft 41's operation. The bearing installation is existing technology and will not be discussed in detail here. A first reversing gear 42 is fixedly connected to the end of the outer wall of the drive shaft 41. The second reversing gear 43 is fixedly installed at the bottom of the adjusting screw 34, and the second reversing gear 43 meshes with the first reversing gear 42. Figure 3As shown, when the drive shaft 41 is rotated, the drive shaft 41 can drive the two adjusting screws 34 to rotate synchronously through the two first reversing gears 42 and the two second reversing gears 43. The braking unit is set between the drive shaft 41 and the fixed housing 31. Under the action of the braking unit, the stability of the drive shaft 41 when it is stationary can be guaranteed, thereby ensuring the stability of the vertical heat exchanger after the adjustment is completed.

[0020] Furthermore, the braking unit includes a first ring 441 and a first brake bolt 442. The first ring 441 is fixedly sleeved on the outside of the drive shaft 41. The outer wall of the first brake bolt 442 is threadedly connected to the first ring 441. One end of the first brake bolt 442 is pressed and fitted against the fixed housing 31, so that the first brake bolt 442 can brake the first ring 441, thereby braking the drive shaft 41.

[0021] Example 2: Unlike Example 1, as follows... Figure 4 As shown, the braking unit includes a second ring 443 and a fixing block 444. The second ring 443 is fixedly sleeved on the outside of the drive shaft 41, and the fixing block 444 is fixedly connected to the top of one side of the fixed housing 31. A second brake bolt 445 is threaded onto the fixing block 444. The bottom of the second brake bolt 445 is pressed and fitted against the second ring 443, so that the second brake bolt 445 presses against the outer wall of the second ring 443, thereby braking the second ring 443 and thus braking the drive shaft 41.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
