Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a novel shell-and-tube heat exchanger. Background Technology

[0002] Tubular heat exchangers are mainly composed of a shell, tube bundle, tube sheet, and end caps. The shell is mostly circular and contains parallel tube bundles, with both ends of the tube bundles fixed to the tube sheet.

[0003] In existing new shell-and-tube heat exchangers, the base structure is directly welded or fixed to the outside of the shell-and-tube heat exchanger during use. This makes it difficult for personnel to quickly disassemble and assemble the heat exchanger according to the usage situation during maintenance. As a result, the installation between the body and the base is not convenient. At the same time, during heat exchange, a fluid enters from the connecting pipe of the end cap, flows in the tube, and flows out from the outlet pipe at the other end of the end cap. This causes poor positioning of the installation plug, which makes it easy for personnel to misalign the installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel shell-and-tube heat exchanger, which has the advantages of stable installation between the body and the base and positioning and docking of the installed end caps, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: A novel shell-and-tube heat exchanger includes a tube body, a base overlapping the outer wall of the tube body, a controller fixedly connected to the outer wall of the base, a motor fixedly connected to the outer wall of the base, a screw fixedly mounted on the power output shaft of the motor, a slider threadedly connected to the outer wall of the screw, a stabilizing plate fixedly connected to the top of the slider, a fixing rod fixedly connected to the outer wall of the tube body, a mounting bolt threadedly connected to the inner wall of the fixing rod, a head threadedly connected to the outer wall of the mounting bolt, a first magnet fixedly mounted on the outer wall of the head, and a second magnet fixedly connected to the inner wall of the tube body.

[0006] As a preferred technical solution of this utility model: a clamping plate is fixedly connected to the inner wall of the tube body, and a heat exchange tube is fixedly installed on the inner wall of the clamping plate.

[0007] As a preferred technical solution of this utility model: a sealing ring is fixedly connected to the outer wall of the end cap, and the number of mounting bolts is several, and the several mounting bolts are evenly distributed on the outer wall of the end cap.

[0008] As a preferred technical solution of this utility model: the outer walls of the first magnet and the second magnet are attached together, and the N pole and S pole of the second magnet and the first magnet are respectively arranged to correspond to each other.

[0009] As a preferred technical solution of this utility model: the controller and the motor are electrically connected, the screw is composed of a positive thread rod and a negative thread rod, and the positive thread rod and the negative thread rod are threadedly connected to the slider.

[0010] As a preferred technical solution of this utility model: the outer walls of the two stabilizing plates are semi-circular, and the outer walls of the two stabilizing plates are in contact with the outer wall of the tube.

[0011] As a preferred technical solution of this utility model: the number of stabilizing plates is two, and the outer walls of the two stabilizing plates are fixedly connected with anti-slip points.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This novel shell-and-tube heat exchanger, through the control controller, the motor drives the screw to rotate in the forward direction, causing the slider to move closer to the stabilizing plates. When the motor drives the screw to rotate in the reverse direction, the slider moves the stabilizing plates away from each other. Anti-slip points are fixedly connected to the outer walls of the two stabilizing plates. The two stabilizing plates are clamped to the outer wall of the tube body, which improves the stability of the tube body during operation and prevents deviation.

[0013] 2. This novel shell-and-tube heat exchanger uses external force to rotate the mounting bolts. The mounting bolts are threaded through the inner wall of the end cap and sealing ring to the fixing rod, which allows the end cap to drive the first magnet to be tightly installed against the outer wall of the tube body, preventing loosening. By setting the N and S poles of the second magnet and the first magnet to correspond, when the end cap drives the first magnet to come into contact with the second magnet, the second magnet attracts the first magnet, thereby achieving rapid positioning and avoiding installation misalignment.

[0018] In the above structure, by installing the end cap 6, the inner wall of the pipe body 1 is shielded and sealed, so that personnel can disassemble and assemble the end cap 6 when the equipment needs to be maintained, thus improving the practicality of the equipment.

[0019] In a preferred embodiment: a clamping plate 16 is fixedly connected to the inner wall of the tube body 1, and a heat exchange tube 9 is fixedly installed on the inner wall of the clamping plate 16.

[0020] In the above structure, the card plate 16 is one of the core internal components in the heat exchange process through the inner wall of the tube 1. Its core function is to optimize the flow state of the shell-side fluid. By changing the fluid path, increasing the flow velocity and turbulence, the goal of "enhancing heat transfer efficiency, protecting heat exchange tube 9, and stabilizing equipment structure" can be achieved.

[0021] In a preferred embodiment: a sealing ring 11 is fixedly connected to the outer wall of the end cap 6, and there are several mounting bolts 7, which are evenly distributed on the outer wall of the end cap 6.

[0022] In the above structure, the mounting bolt 7 is rotated by external force. The mounting bolt 7 is threadedly connected to the fixing rod 8 through the inner wall of the end cap 6 and the sealing ring 11, so that the end cap 6 drives the first magnet 10 to be tightly installed with the outer wall of the tube body 1, thus avoiding loosening.

[0023] In a preferred embodiment: the outer walls of the first magnet 10 and the second magnet 12 are attached together, and the N poles and S poles of the second magnet 12 and the first magnet 10 are arranged correspondingly.

[0024] In the above structure, by setting the N pole and S pole of the second magnet 12 and the first magnet 10 to correspond, when the end cap 6 drives the first magnet 10 to fit with the second magnet 12, the second magnet 12 and the first magnet 10 attract each other, thereby achieving rapid positioning and avoiding misalignment during installation.

[0025] In a preferred embodiment: the controller 3 and the motor 4 are electrically connected, the screw 13 is composed of a positive thread and a negative thread, and the positive thread and the negative thread are threadedly connected to the slider 14.

[0026] In the above structure, by controlling the controller 3, the motor 4 drives the screw 13 to rotate in the forward direction, so that the slider 14 drives the stabilizing plate 5 to move closer to each other. When the motor 4 drives the screw 13 to rotate in the reverse direction, the slider 14 drives the stabilizing plate 5 to move further apart.

[0027] In a preferred embodiment: the outer walls of the two stabilizing plates 5 are semi-circular, and the outer walls of the two stabilizing plates 5 are in contact with the outer wall of the tube body 1.

[0028] In a preferred embodiment, there are two stabilizing plates 5, and the outer walls of the two stabilizing plates 5 are fixedly connected with anti-slip points 15.

[0029] In the above structure, anti-slip points 15 are fixedly connected to the outer walls of two stabilizing plates 5. The two stabilizing plates 5 are clamped to the outer wall of the tube body 1 by fitting together, so that the stabilizing plates 5 drive the anti-slip points 15 to improve the stability of the tube body 1 during operation and avoid deviation.

[0030] Working principle: By rotating the mounting bolt 7 with external force, the mounting bolt 7 is threadedly connected to the fixing rod 8 through the inner wall of the end cap 6 and the sealing ring 11, so that the end cap 6 drives the first magnet 10 to be tightly installed with the outer wall of the tube body 1, preventing loosening. The N pole and S pole of the second magnet 12 and the first magnet 10 are set to correspond to each other, so that when the end cap 6 drives the first magnet 10 and the second magnet 12 to be in contact, the second magnet 12 and the first magnet 10 are attracted to each other, thereby achieving quick positioning and avoiding installation misalignment. The tube body 1 is placed on the top of the base 2. By controlling the controller 3, the motor 4 drives the screw 13 to rotate in the forward direction, so that the slider 14 drives the stabilizing plate 5 to move closer to each other. When the motor 4 drives the screw 13 to rotate in the reverse direction, the slider 14 drives the stabilizing plate 5 to move away from each other. The outer walls of the two stabilizing plates 5 are fixedly connected with anti-slip points 15. The two stabilizing plates 5 are in contact with the outer wall of the tube body 1 for clamping, so that the stabilizing plates 5 and the anti-slip points 15 improve the stability of the tube body 1 during operation and prevent displacement.
