[0001] The present invention relates to the technical field of heat exchangers, and in particular to a supporting mechanism for supporting a central tube of a heat exchanger and a use method thereof. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization. The heat exchanger industry involves nearly 30 industries such as HVAC, pressure vessels, reclaimed water treatment equipment, chemicals, and petroleum, forming an industrial chain with each other.

[0003] In the prior art, in order to support the central tube of the heat exchanger, baffles are used to partition the central tube at multiple levels and angles to support the central tube. At the same time, multiple baffles mainly play multiple supporting roles. Since the central tube is mostly sleeved or plugged with the baffles, when the central tube is embedded in the outer shell, the baffles are affected by the friction of the inner wall of the outer shell, so that multiple baffle support points are changed, thereby failing to support the central tube well. In addition, the strength of the outer shell on which the central tube is installed is not ideal, so that the outer shell is easily deformed by collision. For this reason, we propose a support mechanism for supporting the central tube of the heat exchanger. Summary of the invention

First, pick up the central tube body (6) on the connecting frame (5) and align it with the conveying channel (21) on the assembly shell (1), then pull the limit pull block (18), so that the limit pull block (18) drives the limit plug (17) and the limit spring (19) to move along the direction on the limit sleeve (16), then pass the central tube body (6) through the conveying channel (21) and embed it into the assembly shell (1), and at the same time, the connecting baffle (9) on the connecting frame (5) also enters the assembly shell (1) to support the central tube body (6), and then release the limit pull block (18) so that the limit spring (19) gives the limit plug (17) a restoring force, so that two of the limit plugs (17) are movably plugged into the corresponding limit ring groove (20) to play a limiting role; S2, then the connecting disk (8) on the connecting frame (5) and the driving disk (11) on the second assembly cover (3) are installed through belt drive, and then the second assembly cover (3) and the first assembly cover (2) are threadedly installed and limited with the assembly housing (1), and then the driving motor (14) is started, and the driving worm wheel (12) on the driving worm (15) is driven by the driving motor (14) to engage, so that the driving shaft (10) and the driving disk (11) on the driving worm wheel (12) are driven to rotate, and then the driving disk (11) is also driven by the belt to rotate the connecting disk (8), and at the same time, the connecting disk (8) also drives the connecting bidirectional screw (7) to rotate, so that the two connecting baffles (9) are close to or away from each other along the direction of the connecting bidirectional screw (7), thereby increasing the support area and strengthening the stabilizing effect of the central tube body (6); S3, simultaneously starting the movable motor (32), driving the second movable bevel gear (34) on the movable rod (33) to rotate through the movable motor (32), and then the second movable bevel gear (34) also drives the movable shaft (29) and the second movable disk (31) on the first movable bevel gear (30) to rotate, and at the same time, the second movable disk (31) drives the first movable disk (27) to rotate through the belt, and then the first movable disk (27) also drives the movable bidirectional screw (26) to rotate; S4, the two movable sliders (23) are moved closer to each other along the direction of the movable bidirectional screw (26), and then the movable slider (23) is slidably installed and guided inside the movable groove, and then the movable slider (23) drives the reinforcing arc plate (25) to move through the movable support plate (24), so that the reinforcing arc plate (25) clamps the assembly shell (1), and at the same time, the reinforcing ribs on the reinforcing arc plate (25) play a role in enhancing the strength of the assembly shell (1); S5, then pull the fixed pull block (38), so that the fixed pull block (38) drives the fixed slider (36) and the fixed spring (37) to slide inside the fixed groove, and then bend and flip the fixed hanging ring (39), so that the fixed hanging ring (39) and its corresponding fixed hook (35) are movably connected to the limit position.
