Description

Technical Field

[0001] This utility model relates to the field of heat exchanger tube production and processing technology, specifically a cleaning device for heat exchanger tube processing. Background Technology

[0002] A heat exchanger tube is a type of pipe with high thermal conductivity and good isothermal properties, capable of rapidly transferring heat energy from one point to another with almost no heat loss. It is typically placed inside the cylinder or shell of a heat exchanger, where the fluid inside the tube exchanges heat with the fluid outside through the tube wall, thus achieving heating or cooling. Heat exchanger tubes have wide applications in industrial production: Chemical industry: used for heat transfer and waste heat recovery in various chemical reaction processes. Power industry: used in cooling systems of power plants, as well as in boiler flue gas waste heat recovery and steam condensation processes. Oil and gas industry: used in oil and gas cooling and heat recovery systems. During the manufacturing and processing of heat exchanger tubes, the outer wall can become contaminated with dirt, impurities, oxide scale, and other pollutants, requiring the use of cleaning equipment.

[0003] Traditional cleaning devices for heat exchanger tube processing typically use a pump and nozzle to rinse and clean the surface of the heat exchanger tubes. However, since the outer surface of the heat exchanger tubes contains not only soft scale but also some hard scale, rinsing alone is insufficient for effective cleaning and can negatively impact product quality. To address these issues, some cleaning devices for heat exchanger tube processing incorporate a reciprocating screw and scraper. The scraper is first brought into contact with the heat exchanger tube surface, and then the reciprocating screw drives the scraper to reciprocate across the surface to remove hard scale, thus ensuring cleaning effectiveness and product quality. However, this method is not suitable for heat exchanger tubes of varying radii, and the reciprocating scraper alone cannot achieve a comprehensive cleaning, reducing its applicability. Therefore, a new cleaning device for heat exchanger tube processing is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cleaning device for heat exchanger tube processing, thereby solving the aforementioned technical problems that not only cannot perform comprehensive cleaning but also reduce applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for heat exchanger tube processing, comprising:

[0006] The device frame, and hydraulic rods provided on the upper and lower surfaces of the device frame, with the telescopic ends of the hydraulic rods extending inward through the outer wall of the device frame and connected to clamping plates, and heat exchange tubes clamped between the clamping plates;

[0007] The driven wheel is located on the outer surface of the hydraulic rod, and the driving wheel is engaged with the outer side of the driven wheel. The first drive motor is coaxially connected to the top of the driving wheel, and the driven wheel and the driving wheel are rotatably connected to the device frame.

[0008] A threaded screw is set on both sides of the device frame, and a second drive motor is coaxially connected to the top of the threaded screw. A sliding block is sleeved on the surface of the threaded screw, and an electric push rod is installed on the surface of the sliding block. The electric push rod extends inward through the outer wall of the device frame and is connected to a side scraper. The hydraulic rod drives the clamping plate on the device frame to clamp and fix the end of the heat exchange tube. The electric push rod drives the side scraper to fit against the surface of the heat exchange tube through the telescopic end on the sliding block. The second drive motor drives the threaded screw to rotate on the device frame. The sliding block drives the electric push rod and the side scraper to move up and down to clean the surface of the heat exchange tube according to the direction of the threaded screw. Since the hydraulic rod is rotatably connected to the device frame, the first drive motor drives the drive wheel on the device frame, which drives the driven wheel. The driven wheel drives the heat exchange tube to rotate through the hydraulic rod and clamping plate, thereby adjusting the cleaning part. At the same time, the two sets of second drive motors can be synchronously controlled to start and rotate through remote controller and synchronous control algorithm. This is a common technology on the market, so it will not be described in detail here. By adjusting the movement of the side scraper and the rotation of the heat exchange tube, not only can heat exchange tubes of different sizes be thoroughly cleaned within a certain range, but the applicability is also improved.

[0009] Preferably, the clamping plate is circular in design and fits tightly against the top and bottom ends of the heat exchange tube. The clamping plate secures both ends of the heat exchange tube, preventing interference with the side scraper's cleaning of the tube surface.

[0010] Preferably, the inner wall of the device frame is uniformly provided with fixing rods, and the fixing rods are cylindrical in shape. The device frame is connected to the corresponding structure through the fixing rods.

[0011] Preferably, each end of the fixed rod is equipped with a telescopic rod, and the telescopic end surface of each telescopic rod is fitted with a compression spring. Under the action of the compression spring, the telescopic end of the telescopic rod can be moved outward.

[0012] Preferably, each telescopic end of the telescopic rod is equipped with a scraper, and the scraper and the surface of the side scraper are in close contact. When the electric push rod moves the side scraper into the device frame, the lower surface of the scraper is inclined, causing the telescopic ends of the side scraper and the electric push rod to move inward through the scraper. The scraper then compresses the compression spring. When the electric push rod moves the side scraper out of the device frame to reset, the telescopic end of the telescopic rod, under the action of the compression spring, causes the scraper to be in close contact with the surface of the side scraper during the movement, thereby cleaning the dirt adhering to the surface of the side scraper during the reset process, thus ensuring the cleaning effect on the heat exchange tube.

[0013] Preferably, the two ends of the compression spring are respectively attached to the telescopic rod and the scraper. The compression spring can drive the scraper to move outward on the telescopic rod.

[0014] Compared with the prior art, the present invention provides a cleaning device for heat exchanger tube processing, which has the following beneficial effects:

[0015] This cleaning device for heat exchanger tube processing uses a hydraulic rod to clamp and fix the end of the heat exchanger tube body to a clamping plate on the device frame. An electric push rod on a sliding block drives a side scraper to fit against the surface of the heat exchanger tube body via its telescopic end. A second drive motor drives a threaded screw to rotate on the device frame. The sliding block, according to the direction of the threaded screw, drives the electric push rod and the side scraper to move up and down to clean the surface of the heat exchanger tube body. Because the hydraulic rod is rotatably connected to the device frame, the first drive motor drives the drive wheel on the device frame, which in turn drives the driven wheel. The driven wheel, through the hydraulic rod and clamping plate, drives the heat exchanger tube body to rotate, thereby adjusting the cleaning process. By adjusting the movement of the side scraper and the rotation of the heat exchanger tube body, it is possible to comprehensively clean heat exchanger tube bodies of different sizes within a certain range, thus improving applicability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution: a cleaning device for heat exchanger tube processing, comprising: (see details) Figure 1 The device frame 1, and hydraulic rods 2 are provided on the upper and lower surfaces of the device frame 1. The telescopic ends of the hydraulic rods 2 extend inward through the outer wall of the device frame 1 and are connected to clamping plates 6. Heat exchange tubes 7 are clamped between the clamping plates 6.

[0023] Please see Figure 4 A driven wheel 3 is disposed on the outer surface of the hydraulic rod 2, and a driving wheel 4 is engaged on the outer side of the driven wheel 3. A first drive motor 5 is coaxially connected to the top of the driving wheel 4, and the driven wheel 3 and the driving wheel 4 are rotatably connected to the device frame 1.

[0024] Please see Figure 2 A threaded screw 8 is located on both sides of the device frame 1, and a second drive motor 9 is coaxially connected to the top of each threaded screw 8. A sliding block 10 is fitted onto the surface of each threaded screw 8, and an electric push rod 11 is mounted on the surface of each sliding block 10. The electric push rod 11 extends inward through the outer wall of the device frame 1 and is connected to a side scraper 12. A hydraulic rod 2 drives a clamping plate 6 on the device frame 1 to clamp and fix the end of the heat exchange tube 7. The electric push rod 11, via its telescopic end on the sliding block 10, drives the side scraper 12 to adhere to the surface of the heat exchange tube 7. The second drive motor 9 drives the threaded screw 8 to rotate on the device frame 1. The sliding block 10, according to the direction of rotation of the threaded screw 8, drives the electric push rod 11 and the side scraper 12 to perform lifting and lowering cleaning movements on the surface of the heat exchange tube 7. Because the hydraulic rod 2 is rotatably connected to the device frame 1, the first drive motor 5... The body 1 drives the drive wheel 4, which in turn drives the driven wheel 3. The driven wheel 3, through the hydraulic rod 2 and the clamping plate 6, drives the heat exchange tube body 7 to rotate, thereby adjusting the cleaning section. At the same time, the two sets of second drive motors 9 can be synchronously controlled to start and rotate via a remote controller and synchronous control algorithm. This is a common technology on the market, so it will not be described in detail here. By adjusting the movement of the side scraper 12 and the rotation of the heat exchange tube body 7, not only can heat exchange tube bodies 7 of different sizes be thoroughly cleaned within a certain range, but also the applicability is improved.

[0025] Please see Figure 4 The clamping plate 6 is circular in design and fits tightly against the top and bottom of the heat exchange tube 7. The clamping plate 6 clamps and fixes both ends of the heat exchange tube 7, preventing any interference with the side scraper 12's cleaning of the heat exchange tube 7's surface.

[0026] Please see Figure 3The inner wall of the device frame 1 is uniformly equipped with fixing rods 13, and the fixing rods 13 are cylindrical in shape. The device frame 1 is connected to the corresponding structure through the fixing rods 13. Each end of the fixing rod 13 is equipped with a telescopic rod 14, and the telescopic end of the telescopic rod 14 is fitted with a compression spring 15. Under the action of the compression spring 15, the telescopic end of the telescopic rod 14 can be moved to the outside of the telescopic rod 14. Each telescopic end of the telescopic rod 14 is equipped with a scraper 16, and the scraper 16 is in close contact with the surface of the side scraper 12. When the electric push rod 11 moves the side scraper 12 into the device frame 1, the inclined design of the lower surface of the scraper 16 causes the telescopic ends of the side scraper 12 and the electric push rod 11 to move inward through the scraper 16, which in turn causes the telescopic ends of the telescopic rod 14 to move inward. The scraper 16 then presses against the compression spring 15. When the electric push rod 11 moves the side scraper 12 outward to reset, the telescopic end of the telescopic rod 14, under the action of the compression spring 15, causes the scraper 16 to fit tightly against the surface of the side scraper 12 during the movement. This cleans the dirt adhering to the surface of the side scraper 12 during the reset process, ensuring effective cleaning of the heat exchange tubes. The two ends of the compression spring 15 are respectively attached to the telescopic rod 14 and the scraper 16. The compression spring 15 can move the scraper 16 outward along the telescopic rod 14.

[0027] This solution: A hydraulic rod 2, mounted on the device frame 1, drives a clamping plate 6 to clamp and fix the end of the heat exchange tube 7. An electric push rod 11, mounted on a sliding block 10, drives a side scraper 12 to contact the surface of the heat exchange tube 7 via its telescopic end. A second drive motor 9 drives a threaded screw 8 to rotate on the device frame 1. The sliding block 10, according to the direction of the threaded screw 8, drives the electric push rod 11 and the side scraper 12 to perform a lifting and lowering cleaning motion on the surface of the heat exchange tube 7. Because the hydraulic rod 2 is rotatably connected to the device frame 1, the first drive motor 5 drives a drive wheel 4 on the device frame 1. The drive wheel 4 drives a driven wheel 3, which in turn drives the heat exchange tube 3 via the hydraulic rod 2 and the clamping plate 6. The tube body 7 rotates to adjust the cleaning section. When the electric push rod 11 drives the side scraper 12 to move into the device frame 1, the lower surface of the scraper 16 is inclined, causing the extension end of the side scraper 12 and the electric push rod 11 to move into the extension end of the extension rod 14 through the scraper 16. The scraper 16 then squeezes the compression spring 15. When the electric push rod 11 drives the side scraper 12 to move out of the device frame 1 and reset, the extension end of the extension rod 14, under the action of the compression spring 15, causes the scraper 16 to fit tightly against the surface of the side scraper 12 during the movement, thereby cleaning the dirt adhering to the surface of the side scraper 12 during the reset process.
