Description

Technical Field

[0001] This application relates to the field of heat exchanger manufacturing technology, and in particular to a flux support device for heat exchangers. Background Technology

[0002] Large-diameter heat exchangers are mostly constructed by welding multiple tanks together. The tanks are made by bending steel plates and then welding them into a cylindrical shape. These cylinders are then welded together to form the tank body. During the tank welding process, the cylinders are first spot-welded, and then the cylinders are circumferentially welded using a rotating support device. When welding the gaps on the inner wall of the cylinder, flux needs to be supplied to the gaps on the outer wall to protect the cylinder during the welding process.

[0003] The existing method involves placing the flux on a support plate. However, as the cylinder rotates, the flux easily falls off, preventing prolonged contact between the flux and the cylinder, ultimately affecting the protective effect. A search has not yet revealed any existing literature disclosing a solution to this problem. Summary of the Invention

[0004] The purpose of this application is to address the limitations of some existing devices in the positioning and clamping process, such as difficulty in continuously clamping steel wires of different specifications and difficulty in adjusting the angle of positioning and clamping according to the position of the steel wire, which reduces the welding accuracy and thus reduces the efficiency of the device. Therefore, a flux support device for heat exchangers is proposed.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A flux support device for a heat exchanger, comprising:

[0007] The support belt is a closed-loop structure with a fixed end connection.

[0008] A first roller assembly is disposed at one end of the support belt;

[0009] A second roller assembly is disposed at the other end of the support belt;

[0010] A support member, wherein the first roller assembly is mounted on one end of the upper surface of the support member, and the second roller assembly is mounted on the other end of the upper surface of the support member.

[0011] Compared with the prior art, the advantages and positive effects of this application include at least the following:

[0012] The support belt of this application can rotate on the first roller assembly and the second roller assembly. The support belt is provided with flux. Compared with the existing flux which is placed directly on the support plate, the flux of this application can have a longer contact with the weld as the support belt rotates, thereby providing better protection for the tank during welding.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-4This application provides a technical solution: a flux support device for a heat exchanger, comprising: a support belt 10, a first roller assembly 20, a second roller assembly 30, and a support member 40. The support belt 10 of this application is a closed-loop structure with a fixed connection at both ends; for example, the support belt 10 can be a rubber conveyor belt or a nylon conveyor belt. The first roller assembly 20 of this application is disposed at one end of the support belt 10, wherein the support belt 10 is rotatable within the first roller assembly 20. The second roller assembly 30 of this application is disposed at the other end of the support belt 10, and the support belt 10 is rotatable within the second roller assembly 30; that is, the support belt 10 can circulate on the first roller assembly 20 and the second roller assembly 30. In order to fix the first roller assembly 20 and the second roller assembly 30, the present application also installs the first roller assembly 20 at one end of the upper surface of the support member 40 and the second roller assembly 30 at the other end of the upper surface of the support member 40. For example, the first roller assembly 20 and the second roller assembly 30 of the present application can be welded and fixed to the upper surface of the support member 40. Preferably, the support member 40 of the present application can be a support plate or a support frame. The flux support device 300 of this application is disposed below the tank body 100 (or cylinder), and is also rotatably connected to the bottom of the tank body 100 on a rolling support device 200. The rolling support device 200 can drive the tank body 100 to rotate. The upper surface of the support belt 10 of this application is provided with flux, and the support belt 10 is disposed at the weld of the tank body 100. When welding is performed inside the tank body 100, the flux outside can protect the tank body 100, and the support belt 10 can rotate with the tank body 100, thereby ensuring that the flux and the weld of the tank body 100 are in contact for a longer period of time. Compared with the prior art, the flux of this application can protect the tank body 100 for a longer period of time, thus improving the welding quality.

[0021] In a preferred embodiment of this application, the first roller assembly 20 includes a first roller 21 and a first bracket 22. The first roller 21 is disposed inside one end of the support belt 10, i.e., the support belt 10 is fitted onto the first roller 21 and can rotate on the first roller 21. The first bracket 22 is fixedly mounted on the upper surface of the support member 40; preferably, the first bracket 22 is welded to the upper surface of the support member 40. The first bracket 22 is provided with a first support groove 25; preferably, the first support groove 25 is an open structure. The first roller 21 rotates on the first bracket 22 via a first connecting shaft 23. Specifically, there are two first brackets 22, and the two first brackets 22 have the same structure. The first roller 21 is fixedly connected to the first connecting shaft 23, and both ends of the first connecting shaft 23 protrude beyond the outer side of the first roller 21. The first connecting shaft 23 is placed on the first support groove 25, thus allowing the first roller 21 to rotate on the first bracket 22. The opening direction of the first support groove 25 in this application is obliquely upward. Preferably, the opening direction of the first support groove 25 forms an angle of 10-80° with the vertical direction. More preferably, the opening direction of the first support groove 25 forms an angle of 30-60° with the vertical direction. This opening structure of the first support groove 25 facilitates the installation of the first roller 21 and the support belt 10, and the angle also prevents the first roller 21 from falling off the first bracket 22. The first connecting shaft 23 in this application is also fitted with a first bearing 24, which is interference-fitted with the first support groove 25. This reduces friction and wear when the first roller 21 rotates on the first bracket 22, thereby extending the service life of the equipment.

[0022] In a preferred embodiment of this application, the second roller assembly 30 includes a second roller 31 and a second bracket 32. The second roller 31 is disposed at the other end inside the support belt 10, i.e., the support belt 10 is sleeved on the second roller 31 and can rotate within the second roller 31. The second bracket 32 ​​is fixedly mounted on the upper surface of the support member 40. Preferably, the lower end of the second bracket 32 ​​is fixedly welded to the upper surface of the support member 40. The second bracket 32 ​​is provided with a second support groove 321. Preferably, the second support groove 321 is horizontally positioned. A matching second bearing 312 is disposed within the second support groove 321. There is a certain friction between the second bearing 312 and the second support groove 321. The second bearing 312 is interference-fitted with a second connecting shaft 311, which is fixedly connected to the second roller 31. Preferably, there are two second brackets 32, and the two second brackets 32 can have the same structure. The second connecting shaft 311 can rotate on the second bearing 312, and the second roller 31 of this application can rotate on the second bearing 312, that is, the second roller 31 of this application can rotate on the second support 32. The second bearing 312 of this application is also connected to the first connecting rod 38. Preferably, the first connecting rod 38 of this application has a U-shaped structure, and the two ends of the first connecting rod 38 are also fixedly connected to the third bearing 37. Specifically, the outer wall of the third bearing 37 is fixedly connected to the first connecting rod 38, and the inner wall of the third bearing 37 is also fixedly connected to one end of the lead screw 36, that is, the lead screw 36 can rotate on the third bearing 37, and the lead screw 36 can rotate relative to the first connecting rod 38. The lead screw 36 of this application is also provided with a threaded nut 33. The nut 33 is connected to one end of the second connecting rod 34, and the other end of the second connecting rod 34 is fixedly connected to the second bracket 32. Preferably, there are two second connecting rods 34 in this application. One second connecting rod 34 is fixedly connected to the outside of the nut 33 at one end and fixedly connected to the second bracket 32 ​​at the other end. The other second connecting rod 34 is fixedly connected to the other outside of the nut 33 at one end and fixedly connected to another second bracket 32 ​​at the other end. Preferably, the two second connecting rods 34 in this application are symmetrically arranged about the nut 33. The other end of the lead screw 36 in this application is fixedly connected to the handle 35. By setting the handle 35, it is easier to rotate the lead screw 36. When the handle 35 is rotated, the lead screw 36 rotates and drives the first connecting rod 38 to move. The first connecting rod 38 can drive the second roller 31 to move in the second support groove 321, thereby adjusting the tightness of the support belt 10, so as to better fit the tank 100 with different outer diameters.The second roller 31 of this application has a limiting ring 313 on at least one side of its outer wall. Preferably, the second roller 31 has limiting rings 313 on both sides of its outer wall. This can limit the support belt 10 and prevent the support belt 10 from deviating from the weld of the tank body 100 when rotating. The first roller 21 of this application has a limiting ring on at least one side of its outer wall.

[0023] In a preferred embodiment of this application, the support member 40 is mounted on the support block 50, and the height of the support block 50 can be adjusted according to the position of the tank 100.
