Description

Technical Field

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

[0002] A tubular heat exchanger, also known as a shell-and-tube heat exchanger, is a device that uses the tube wall as a heat transfer interface to achieve heat exchange between two or more fluids. It introduces two fluids at different temperatures into different channels (tube side and shell side), and utilizes the thermal conductivity of the tube wall to transfer the heat of the high-temperature fluid to the low-temperature fluid, ultimately achieving process objectives such as heating, cooling, condensation, or evaporation.

[0003] While existing devices can exchange heat, they are not convenient for cleaning the inside of the tubular heat exchanger, which leads to a decrease in heat exchange efficiency over long-term use. Furthermore, they are not convenient for supporting the tubular heat exchanger, which can cause it to collapse during use. Therefore, an automatic descaling shell-and-tube heat exchanger is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an in-tube automatic descaling shell-and-tube heat exchanger, which has the advantages of good cleaning effect and good support effect, and solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: an automatic descaling shell-and-tube heat exchanger, comprising a shell-and-tube heat exchanger body, a fixing block fixedly mounted on the outer wall of the shell-and-tube heat exchanger body, a second motor fixedly mounted on the outer wall of the fixing block, a rotating rod fixedly mounted on the power output shaft of the second motor, a tension rope fixedly mounted on the outer wall of the rotating rod, a placement block and an installation block fixedly mounted on the outer wall of the shell-and-tube heat exchanger body respectively, a rotating column rotatably connected to the inner wall of the placement block, a support rod fixedly mounted on the outer wall of the rotating column, a spring fixedly mounted on the outer wall of the installation block, a first motor fixedly mounted on the outer wall of the shell-and-tube heat exchanger body, a rotating shaft fixedly mounted on the power output shaft of the first motor, and a scraping component provided on the outer wall of the rotating shaft.

[0006] As a preferred technical solution of this utility model: a controller is fixedly installed at the end of the tubular heat exchanger body closer to the motor, and a discharge port is fixedly installed at the end of the tubular heat exchanger body away from the controller.

[0007] As a preferred technical solution of this utility model: the scraping component includes a connecting block, the inner wall of the connecting block is provided with a placement groove, the inner wall of the placement groove is respectively fixedly assembled with a spring and a support block, the inner wall of the support block is rotatably connected with a cylinder, the outer wall of the cylinder is fixedly assembled with a connecting rod, the inner wall of the placement groove is slidably connected with a pressure block, the inner wall of the pressure block is rotatably connected with an installation rod, and the top of the pressure block is fixedly assembled with a scraper.

[0008] As a preferred technical solution of this utility model: the connecting block is fixedly assembled with the rotating shaft, and the second spring is fixedly assembled with the pressure block.

[0009] As a preferred technical solution of this utility model: the discharge port is connected to the inner wall of the tubular heat exchanger body, and both motor one and motor two are electrically connected to the controller.

[0010] As a preferred technical solution of this utility model: the number of scraping components is several groups, and the several groups of scraping components are respectively located on the outer wall of the rotating shaft.

[0011] As a preferred technical solution of this utility model: the scraper block is in contact with the inner wall of the tubular heat exchanger body, and the connecting rod is fixedly assembled with the mounting rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this shell-and-tube heat exchanger with automatic descaling inside the tube, when the tube heat exchanger body is placed, the controller sends a signal to cause the power output shaft of motor two to rotate after receiving the signal. Motor two drives the rotating rod to rotate, and the rotating rod applies pressure to the tension rope. Under pressure, the tension rope drives the support rod and rotating column to rotate on the inner wall of the placement block, so that the support rod rotates to the bottom of the tube heat exchanger body to support the tube heat exchanger body. When the tube heat exchanger body is retracted, the reverse rotation of the power output shaft of motor two and the elastic potential energy of spring one cause the support rod to return to its initial state.

[0013] 2. In this automatic descaling shell-and-tube heat exchanger, when cleaning the inside of the heat exchanger body, the controller sends a signal to the power output shaft of motor one, which in turn rotates the connecting block. This rotating block then drives the scraper to remove the scale from the inner wall of the heat exchanger body. During scraping, the scraper applies pressure, causing it to move a pressure block along the inner wall of the placement tank. This movement of the pressure block then applies pressure to the mounting rod, causing the connecting rod to rotate the cylinder along the inner wall of the support block. Furthermore, the movement of the pressure block also applies pressure to spring two, releasing its elastic potential energy, thus achieving the cleaning effect. Attached Figure Description

[0017] Please see Figure 1 - Figure 5 An automatic descaling shell-and-tube heat exchanger includes a shell-and-tube heat exchanger body 1. A fixing block 3 is fixedly mounted on the outer wall of the shell-and-tube heat exchanger body 1. A motor 8 is fixedly mounted on the outer wall of the fixing block 3. A rotating rod 9 is fixedly mounted on the power output shaft of the motor 8. A tension rope 10 is fixedly mounted on the outer wall of the rotating rod 9. A placement block 12 and an installation block 11 are fixedly mounted on the outer wall of the shell-and-tube heat exchanger body 1. A rotating column 13 is rotatably connected to the inner wall of the placement block 12. A support rod 14 is fixedly mounted on the outer wall of the rotating column 13. A spring 15 is fixedly mounted on the outer wall of the installation block 11. A motor 4 is fixedly mounted on the outer wall of the shell-and-tube heat exchanger body 1. A rotating shaft 5 is fixedly mounted on the power output shaft of the motor 4. A scraping component 6 is provided on the outer wall of the rotating shaft 5. In the above structure, when the tubular heat exchanger body 1 is placed, the controller 2 sends a signal to cause the motor 8 to start rotating after receiving the signal. After the motor 8 rotates, it drives the rotating rod 9 to rotate. During the rotation, the rotating rod 9 will apply pressure to the tension rope 10. After being subjected to pressure, the tension rope 10 will drive the support rod 14 and the rotating column 13 to rotate on the inner wall of the placement block 12 until the support rod 14 rotates to the bottom of the tubular heat exchanger body 1, thus supporting the tubular heat exchanger body 1. In addition, when the tubular heat exchanger body 1 is retracted, the support rod 14 will return to its initial state by means of the reverse rotation of the motor 8's power output shaft and the elastic potential energy of the spring 15.

[0018] In a preferred embodiment: a controller 2 is fixedly mounted on one end of the tubular heat exchanger body 1 near the motor 4, and a discharge port 7 is fixedly mounted on the other end of the tubular heat exchanger body 1 away from the controller 2. In the above structure, the controller 2 controls the equipment to operate, and the discharge port 7 discharges the descaling material.

[0019] In a preferred embodiment: the scraping component 6 includes a connecting block 601, the inner wall of the connecting block 601 is provided with a placement groove 602, the inner wall of the placement groove 602 is respectively fixedly assembled with a spring 604 and a support block 603, the inner wall of the support block 603 is rotatably connected with a cylinder 605, the outer wall of the cylinder 605 is fixedly assembled with a connecting rod 606, the inner wall of the placement groove 602 is slidably connected with a pressure block 607, the inner wall of the pressure block 607 is rotatably connected with an installation rod 608, and the top of the pressure block 607 is fixedly assembled with a scraper 609; In the above structure, when cleaning the dirt inside the tubular heat exchanger body 1, the controller 2 sends a signal, causing the motor 4 to receive the signal and start rotating its power output shaft. The power output shaft of the motor 4 drives the connecting block 601 to rotate, which in turn causes the connecting block 601 to drive the scraper 609 to scrape away the dirt on the inner wall of the tubular heat exchanger body 1. When the scraper 609 scrapes away the dirt, the dirt will apply pressure to the scraper 609, causing the scraper 609 to drive the pressure block 607 to move on the inner wall of the placement groove 602 after being pressed. When the pressure block 607 moves, it will drive the mounting rod 608 to apply pressure to the connecting rod 606, causing the connecting rod 606 to drive the cylinder 605 to rotate on the inner wall of the support block 603. In addition, when the pressure block 607 moves, it will also apply pressure to the spring 604, causing the spring 604 to release its elastic potential energy, thereby achieving the cleaning effect.

[0020] In a preferred embodiment: the connecting block 601 is fixedly assembled with the rotating shaft 5, and the second spring 604 is fixedly assembled with the pressure block 607; In the above structure, the scraping component 6 is limited and fixed by the rotating shaft 5, making the scraping component 6 more stable during use. The second spring 604 is limited by the placement groove 602 and the pressure block 607 to prevent the second spring 604 from falling off when its elastic potential energy is released.

[0021] In a preferred embodiment: the discharge port 7 is connected to the inner wall of the tubular heat exchanger body 1, and both motor 4 and motor 8 are electrically connected to the controller 2. In the above structure, the scale inside the tubular heat exchanger body 1 is removed through the discharge port 7, and the controller 2 sends a signal to the equipment to start operation after receiving the signal.

[0022] In a preferred embodiment: there are several groups of scraping components 6, and the several groups of scraping components 6 are respectively located on the outer wall of the rotating shaft 5; In the above structure, several scraping components 6 are used to clean the scale inside the tubular heat exchanger body 1.

[0023] In a preferred embodiment: the scraper 609 is in contact with the inner wall of the tubular heat exchanger body 1, and the connecting rod 606 is fixedly assembled with the mounting rod 608. In the above structure, the scraper 609 is used to clean the inside of the tubular heat exchanger body 1, and the connecting rod 606 is used to connect the cylinder 605 and the mounting rod 608.

[0024] Working principle: When placing the tubular heat exchanger body 1, the controller 2 sends a signal, causing the power output shaft of motor 8 to start rotating upon receiving the signal. The rotation of motor 8 drives the rotating rod 9 to rotate, which in turn applies pressure to the tension rope 10. This pressure causes the support rod 14 and rotating column 13 to rotate on the inner wall of the placement block 12 until the support rod 14 reaches the bottom of the tubular heat exchanger body 1, providing support. When retrieving the tubular heat exchanger body 1, the reverse rotation of the power output shaft of motor 8 and the elastic potential energy of spring 15 cause the support rod 14 to return to its initial state. Similarly, when cleaning the dirt inside the tubular heat exchanger body 1, the controller 2 sends a signal... Upon receiving the signal, motor 4's power output shaft begins to rotate. The power output shaft of motor 4 drives the connecting block 601 to rotate, and the connecting block 601 drives the scraper 609 to scrape away the dirt on the inner wall of the tubular heat exchanger body 1. When the scraper 609 scrapes away the dirt, the dirt will apply pressure to the scraper 609. After being subjected to pressure, the scraper 609 will drive the pressure block 607 to move on the inner wall of the placement groove 602. When the pressure block 607 moves, it will drive the mounting rod 608 to apply pressure to the connecting rod 606, causing the connecting rod 606 to drive the cylinder 605 to rotate on the inner wall of the support block 603. In addition, when the pressure block 607 moves, it will also apply pressure to the spring 604, causing the spring 604 to release its elastic potential energy, thereby achieving the cleaning effect.
