Description

Technical Field

[0001] The utility model relates to the technical field of graphite heat exchangers, in particular to a corrosion-resistant shell and tube type graphite heat exchanger. Background Art

[0002] Graphite heat exchanger is a heat exchanger whose heat transfer components are made of graphite. The working principle of graphite heat exchanger is: based on the acid corrosion resistance and good thermal conductivity of graphite, graphite is used to make flow guide devices. When the two media pass through each other, the high-temperature medium continuously transfers heat to the graphite heat exchanger, and the low-temperature medium continuously obtains heat from the heat exchanger, thereby realizing heat exchange.

[0003] Prior art includes a utility model with publication number CN216745602U, which discloses a corrosion-resistant shell and tube graphite heat exchanger. The patent adopts a shell and tube graphite heat exchanger, wherein a water inlet is fixedly connected to the top of the shell and tube graphite heat exchanger, a water outlet is fixedly connected to the bottom of the shell and tube graphite heat exchanger, a support frame is arranged at the bottom of the shell and tube graphite heat exchanger, and the shell and tube graphite heat exchanger includes a shell, a high-temperature medium port is opened on the left side of the shell, and a low-temperature medium port is opened on the right side of the shell. The utility model solves the problem that the existing shell and tube graphite heat exchanger has poor corrosion resistance, resulting in reduced working efficiency of the equipment and increased use cost.

[0004] The inventor discovered in his daily work that in the process of replacing the inner wall of the equipment, there is a limit ring. When replacing it, the user needs to use tools to move and replace the limit ring. The use of tools is too cumbersome, resulting in reduced use and work efficiency. Utility Model Content

[0005] The utility model aims to solve the shortcoming in the prior art that it is difficult to quickly replace the graphite tube inside the equipment, and proposes a corrosion-resistant shell-and-tube graphite heat exchanger.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a corrosion-resistant shell and tube graphite heat exchanger, comprising a pipeline and a moving device, a first connector is provided at one end of the pipeline, a second connector is provided at one end of the pipeline, a limiting ring is provided inside the pipeline, a graphite tube is provided on the inner wall of the limiting ring, the moving device is provided inside the limiting ring, the moving device comprises a moving block and a slide groove, the slide groove is opened on the inner wall of the pipeline, the moving block is fixedly connected to the side of the limiting ring, and the moving block is slidably connected to the inner wall of the slide groove.

[0007] Furthermore, a groove is provided inside the limiting ring, and a connecting column is slidably connected inside the groove. By providing the connecting column, the handle can be limited in movement, thereby reducing the situation where the handle is difficult to limit when the device is in use, making it difficult for the user to move the handle.

[0008] Furthermore, one end of the connecting column is fixedly connected to a first spring, and one end of the first spring away from the connecting column is fixedly connected to the inner wall of the groove. The first spring is provided to facilitate applying a restoring elastic force to the connecting column.

[0009] Furthermore, a rotation groove is formed at one end of the connecting column away from the first spring, and a handle is rotatably connected to the inner wall of the rotation groove. The handle is provided to facilitate pulling by the user.

[0010] Furthermore, a supporting device is provided on the surface of the pipeline, and the supporting device includes a limiting plate and a pulling hole. The pulling hole is provided on the surface of the limiting ring, and the limiting plate is fixedly connected to the surface of the pipeline. The limiting plate is internally slidably connected to the supporting plate, and the pulling hole is internally slidably connected to the clamping plate. A clamping groove is provided on the surface of the supporting plate, and the clamping plate is clamped with the inside of the clamping groove. By providing the supporting plate, the limiting ring can be supported, which reduces the risk of the limiting ring easily contacting the ground when the equipment is in use, causing the graphite tube inside the limiting ring to bend.

[0011] Furthermore, one end of the card plate away from the card slot is fixedly connected to a second spring, and one end of the second spring away from the card plate is fixedly connected to the inner wall of the pull hole. The second spring is provided to facilitate applying a restoring elastic force to the card plate.

[0012] Furthermore, a pull block is fixedly connected to the side of the card plate, and the pull block is slidably connected to the inside of the pull hole. The pull block is provided to facilitate the movement of the card plate.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the device is in use, the user installs the device at a place where heat exchange is required, and then passes the liquid that needs to be exchanged through the inside of the device for heat exchange and cooling. When replacing the inside of the device, the user pulls the handle, and then the handle moves to drive the connecting column to move. When the connecting column moves, it drives the first spring to displace and deform to generate elastic force. Then, after the connecting column is separated from the inside of the pulling groove, the handle is rotated inside the rotating groove to make the handle and the limit ring perpendicular to each other, and the handle is pulled to drive the limit ring to move. The movement of the limit ring drives the moving block to move and slide and connect inside the sliding groove. By setting a moving device, the limit ring can be effectively replaced, which plays a role in quickly replacing the limit ring, reducing the need for the user to use tools to move and replace the limit ring when the device is in use. The use of tools is too cumbersome, resulting in reduced use and work efficiency, thereby improving the work efficiency of the user.

[0015] 2. In the utility model, by providing a supporting device, when the equipment is replaced, the user pulls the pulling block, and the movement of the pulling block drives the card plate to move, and the movement of the card plate drives the second spring to be displaced and deformed to generate elastic force, and then the supporting plate is pulled to the lower end of the card plate, and then the restraint of the card plate is released, and then the card plate drives the second spring to be displaced and deformed to generate elastic force, and then the card plate is connected with the inside of the card slot, and the supporting plate and the limit ring move in the same position. By providing the supporting device, the limit ring is effectively supported, and the graphite tube inside the limit ring is supported, which reduces the risk of damage to the graphite tube when the equipment is in use and the graphite tube is replaced. Since the graphite tube is relatively fragile, the graphite tube is prone to damage during movement and replacement, thereby improving the practicability of the equipment.

[0023] The specific configuration and functions of the moving device 6 and the supporting device 7 will be described in detail below.

[0024] In this embodiment: the moving device 6 is arranged inside the limiting ring 4, and the moving device 6 includes a moving block 61 and a slide groove 62, the slide groove 62 is opened on the inner wall of the pipeline 1, the moving block 61 is fixedly connected to the side of the limiting ring 4, and the moving block 61 is slidably connected to the inner wall of the slide groove 62.

[0025] Specifically, a groove 63 is formed inside the limiting ring 4 , and a connecting column 64 is slidably connected inside the groove 63 .

[0026] In this embodiment: by providing a connecting column 64, the handle 65 can be limited in movement, which reduces the difficulty of limiting the handle 65 when the device is in use, making it difficult for the user to move the handle 65.

[0027] Specifically, one end of the connecting column 64 is fixedly connected to the first spring 66 , and one end of the first spring 66 away from the connecting column 64 is fixedly connected to the inner wall of the groove 63 . The first spring 66 is provided to facilitate applying a restoring elastic force to the connecting column 64 .

[0028] Specifically, a rotation groove 67 is formed at one end of the connecting column 64 away from the first spring 66 , and a handle 65 is rotatably connected to the inner wall of the rotation groove 67 . The handle 65 is provided to facilitate pulling by the user.

[0029] In this embodiment: a supporting device 7 is provided on the surface of the pipeline 1, and the supporting device 7 includes a limiting plate 71 and a pulling hole 73. The pulling hole 73 is provided on the surface of the limiting ring 4, the limiting plate 71 is fixedly connected to the surface of the pipeline 1, the limiting plate 71 is internally slidably connected to the supporting plate 72, the pulling hole 73 is internally slidably connected to the clamping plate 74, a clamping groove 77 is provided on the surface of the supporting plate 72, and the clamping plate 74 is clamped with the inside of the clamping groove 77.

[0030] In this embodiment: by providing a support plate 72, the limit ring 4 can be supported, which reduces the risk of the limit ring 4 easily coming into contact with the ground when the device is in use, causing the graphite tube 5 inside the limit ring 4 to bend.

[0031] Specifically, one end of the card plate 74 away from the card slot 77 is fixedly connected to the second spring 75, and one end of the second spring 75 away from the card plate 74 is fixedly connected to the inner wall of the pulling hole 73.

[0033] Working principle: when the equipment is in use, the user installs the equipment at a place where heat exchange is required, and then passes the liquid that needs to be heat exchanged through the inside of the equipment for heat exchange and cooling. When replacing the inside of the equipment, the user pulls the handle 65, and then the handle 65 moves to drive the connecting column 64 to move. When the connecting column 64 moves, it drives the first spring 66 to displace and deform to generate elastic force. Then, after the connecting column 64 is separated from the inside of the pull groove 63, the handle 65 is rotated inside the rotating groove 67 to make the handle 65 and the limit ring 4 perpendicular, and the handle 65 is pulled to drive the limit ring 4 to move.

By setting the moving device 6, the limit ring 4 is effectively replaced, which plays a role in quickly replacing the limit ring 4, reducing the need for the user to use tools to move and replace the limit ring 4 when the equipment is in use. The use of tools is too cumbersome, resulting in reduced use and work efficiency, thereby improving the work efficiency of the user.

[0034] When the equipment is replaced, the user pulls the pull block 76, and the pull block 76 moves, which drives the clamping plate 74 to move. The movement of the clamping plate 74 drives the second spring 75 to displace and deform to produce elastic force, and then the support plate 72 is pulled to the lower end of the clamping plate 74, and the restraint of the clamping plate 74 is released. Then the clamping plate 74 drives the second spring 75 to displace and deform to produce elastic force, and then the clamping plate 74 is clamped with the inside of the clamping groove 77, and the support plate 72 and the limit ring 4 move in the same position. By setting the supporting device 7, the limit ring 4 is effectively supported, and the graphite tube 5 inside the limit ring 4 is supported. This reduces the risk of damage to the graphite tube 5 when the equipment is in use and is replaced. Since the graphite tube 5 is relatively fragile, it is easy to be damaged when it is moved and replaced, thereby improving the practicability of the equipment.
