Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a heat exchanger tube cleaning device. Background Technology

[0002] Shell and tube heaters are widely used in the chemical and sugar industries. Typically, shell and tube heaters have multiple heat exchange tubes inserted into end plates. Not only are there many heat exchange tubes, but after a period of use, scale easily accumulates on the inner wall of the heat exchange tubes. This scale greatly reduces the heat transfer efficiency of the heat exchange tubes, seriously affecting the working efficiency of the shell and tube heater, so that these heat exchange tubes need to be descaled and cleaned regularly.

[0003] In related technologies, heat exchanger tube cleaning equipment involves installing a flushing nozzle on a high-pressure water pipe and placing it inside the heat exchanger tube. The high-pressure water pipe is then moved up and down to flush the inner wall of the heat exchanger tube. However, this method is prone to slippage when driving the water pipe to move up and down. Utility Model Content

[0004] The technical problem to be solved by this invention is how to improve the stability of driving high-pressure water pipes and prevent slippage.

[0005] To solve the above-mentioned technical problems, this utility model provides a heat exchange tube cleaning device, including: annular guide rail, linear guide rail, support, first driving device, second driving device and water pipe moving device;

[0006] The first driving device is used to drive one end of the linear guide rail to move along the annular guide rail and to make the other end of the linear guide rail rotate relative to the support;

[0007] The water pipe moving device is slidably mounted on the linear guide rail. The second driving device is used to drive the water pipe moving device to slide along the linear guide rail. The water pipe moving device includes a housing, a pipe inlet that passes through the housing and allows a high-pressure water pipe to pass through, a belt conveyor assembly mounted on the housing, and auxiliary wheels mounted on the housing. The belt conveyor assembly and the auxiliary wheels are located opposite each other on both sides of the high-pressure water pipe. The belt conveyor assembly includes a driving belt for driving the high-pressure water pipe to move up and down.

[0008] Furthermore, the conveyor assembly also includes a driving component, a driving wheel, and a plurality of driven wheels spaced apart vertically. The driving belt is sleeved on the driving wheel and the driven wheels. The driving component is used to drive the driving wheel to rotate. The driven wheels and the auxiliary wheel are located opposite each other on both sides of the high-pressure water pipe.

[0009] Furthermore, the auxiliary wheels are multiple, and the multiple auxiliary wheels are arranged at intervals between each other.

[0010] Furthermore, the outer surface of the drive belt is provided with a plurality of teeth spaced circumferentially.

[0011] Furthermore, the housing is provided with a floating plate, the auxiliary wheel is rotatably mounted on the floating plate, the floating plate is slidably connected to the housing so that the floating plate can move closer to or away from the high-pressure water pipe, and a spring is provided between the floating plate and the housing.

[0012] Furthermore, the aforementioned heat exchange tube cleaning equipment also includes a moving component connected to the water pipe moving device, wherein the water pipe moving device is slidably connected to the linear guide rail via the moving component;

[0013] The moving component includes a mounting plate with two rows of upper and lower rollers, and the linear guide rail is engaged between the two rows of upper and lower rollers.

[0014] Furthermore, the roller is provided with a groove that engages with the linear guide rail.

[0016] Furthermore, one end of the linear guide rail is slidably connected to the annular guide rail, and the other end of the linear guide rail is rotatably connected to the support, with the support located at the center of the annular guide rail.

[0017] The heat exchanger cleaning equipment provided by the above technical solution has the following advantages compared with the prior art: by setting a conveyor belt and auxiliary wheels in the water pipe moving device, the drive belt of the conveyor belt and the auxiliary wheels are positioned opposite each other on both sides of the high-pressure water pipe, forming a stable clamping and driving structure. When the high-pressure water pipe is moved up and down, the drive belt acts directly on the high-pressure water pipe and provides continuous friction, while the auxiliary wheels provide auxiliary support and guidance, thereby effectively preventing the high-pressure water pipe from slipping during the up and down movement.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 4 As shown, the present invention provides a heat exchange tube cleaning device, including an annular guide rail 1, a linear guide rail 2, a support 3, a first driving device 4, a second driving device 5, and a water pipe moving device 6.

[0028] The first driving device 4 drives one end of the linear guide rail 2 to move along the annular guide rail 1, while simultaneously causing the other end of the linear guide rail 2 to rotate relative to the support 3, forming a stable motion mechanism. The water pipe moving device 6 is slidably mounted on the linear guide rail 2 and is driven by the second driving device 5 to slide along the linear guide rail 2. The water pipe moving device 6 includes a housing 61, a pipe inlet through the housing 61 for the high-pressure water pipe 9 to pass through, a belt conveyor assembly 62 mounted on the housing 61, and auxiliary wheels 63. The belt conveyor assembly 62 and the auxiliary wheels 63 are located opposite each other on both sides of the high-pressure water pipe 9, wherein the belt conveyor assembly 62 includes a driving belt 621 for driving the high-pressure water pipe 9 to move up and down.

[0029] In this system, the support 3 is fixed, while the annular guide rail 1 and the linear guide rail 2 define the movement path of the water pipe moving device 6, allowing it to move to any position within the area of ​​the annular guide rail 1 to clean any heat exchange tube within that area. The first drive device 4 can be mounted on the annular guide rail 1 and connected to the linear guide rail 2. The first drive device 4 can use a motor-driven roller to roll on the annular guide rail 1, moving one end of the linear guide rail 2 along the annular guide rail 1, while the other end of the linear guide rail 2 is rotatably connected to the support 3. Alternatively, the first drive device 4 can be mounted on the support 3, using a motor to drive one end of the linear guide rail 2 to rotate relative to the support 3. The second drive device 5 can use a motor-driven synchronous belt to move the water pipe moving device 6 along the linear guide rail 2, with the water pipe moving device 6 fixedly connected to the synchronous belt.

[0030] By setting a conveyor belt 62 and an auxiliary wheel 63 in the water pipe moving device 6, the drive belt 621 of the conveyor belt 62 and the auxiliary wheel 63 are positioned opposite each other on both sides of the high-pressure water pipe 9, forming a stable clamping and driving structure. When the high-pressure water pipe 9 moves up and down, the drive belt 621 acts directly on the high-pressure water pipe 9 and provides continuous friction, while the auxiliary wheel 63 provides auxiliary support and guidance. This effectively prevents the high-pressure water pipe 9 from slipping during the up and down movement, significantly improving the stability and reliability of driving the high-pressure water pipe 9 and ensuring the continuity and efficiency of the cleaning process.

[0031] To further optimize the transmission efficiency and stability of the belt conveyor assembly 62, this embodiment provides a detailed design for the belt conveyor assembly 62. The belt conveyor assembly 62 includes a driving component 622, a driving wheel 623, and multiple driven wheels 624 spaced vertically. A driving belt 621 is fitted onto the driving wheel 623 and the driven wheels 624 to form a closed-loop transmission system. The driving component 622 drives the driving wheel 623 to rotate, thereby driving the entire driving belt 621 in a cyclical motion. The driving component 622 can be a motor. The driving wheel 623, driven wheels 624, and auxiliary wheels 63 can all rotate relative to the housing 61.

[0032] Specifically, the driven wheel 624 and the auxiliary wheel 63 are positioned opposite each other on both sides of the high-pressure water pipe 9, forming a symmetrical clamping structure. This multi-wheel support design increases the contact area between the drive belt 621 and the high-pressure water pipe 9, resulting in a more uniform pressure distribution. This ensures sufficient friction to drive the water pipe up and down while avoiding damage to the water pipe that may be caused by excessive local pressure.

[0033] To enhance the guiding and supporting effect on the high-pressure water pipe 9, this embodiment uses multiple auxiliary wheels 63, which are arranged vertically at intervals. The multiple auxiliary wheels 63 cooperate with the multiple driven wheels 624 in the conveyor assembly 62 to form continuous support points on the moving path of the high-pressure water pipe 9.

[0034] This multi-point support structure effectively prevents the high-pressure water pipe 9 from bending or swaying during long-distance movement, ensuring that the water pipe always moves stably along the preset straight path. At the same time, multiple auxiliary wheels 63 share the load, reducing wear on individual wheels and extending the service life of the equipment.

[0035] To improve the transmission efficiency between the drive belt 621 and the high-pressure water pipe 9 and further prevent relative slippage, this embodiment provides multiple teeth 625 spaced circumferentially on the outer surface of the drive belt 621. These teeth 625 can form a good meshing effect with the surface of the high-pressure water pipe 9, greatly enhancing the gripping force during transmission.

[0036] Specifically, the toothed structure 625 has elastic deformation capability, and both it and the drive belt 621 are made of rubber, which ensures sufficient friction while avoiding damage to the surface of the high-pressure water pipe 9. Even in humid environments or when the water pipe surface is contaminated with cleaning agent, this toothed structure can still maintain stable transmission performance, effectively overcoming the defect of traditional smooth drive belts that are prone to slippage.

[0037] To accommodate high-pressure water pipes 9 of different diameters and maintain a constant clamping force, this embodiment includes a floating plate 64 structure on the housing 61. An auxiliary wheel 63 is rotatably mounted on the floating plate 64, which is slidably connected to the housing 61, allowing the floating plate 64 to move closer to or further away from the high-pressure water pipe 9 as needed.

[0038] A spring 65 is provided between the floating plate 64 and the housing 61, which provides a continuous clamping force so that the auxiliary wheel 63 always presses against the high-pressure water pipe 9 with appropriate pressure. This adaptive floating structure can compensate for the diameter tolerance and slight shape deviation of the high-pressure water pipe 9, ensuring a stable driving effect under various operating conditions.

[0039] To achieve smooth movement of the water pipe moving device 6 on the linear guide rail 2, such as Figures 1 to 5As shown, this embodiment includes a moving component 8. The water pipe moving device 6 is slidably connected to the linear guide rail 2 via the moving component 8. The moving component 8 includes a mounting plate 81, on which two rows of rollers 82 are provided, and the linear guide rail 2 is precisely engaged between these two rows of rollers 82.

[0040] This double-row roller clamping structure provides stable support and precise guidance for the moving component 8, preventing swaying or deviation during movement. The rollers 82 are made of a low-friction material, ensuring smooth movement while withstanding various loads generated during cleaning operations.

[0041] To further enhance the fitting accuracy between the moving component 8 and the linear guide rail 2, this embodiment provides grooves 83 on the roller 82 that match the shape of the linear guide rail 2. These grooves 83 form a precise fit with the contour of the linear guide rail 2, effectively restricting the degrees of freedom of the moving component 8 in the horizontal and vertical directions.

[0042] The structure of slot 83 not only provides better guidance but also prevents the risk of derailment that may occur during the movement of the moving component 8. This design is particularly suitable for cleaning operations that require frequent start-stop and reversal, ensuring the long-term reliability of the equipment.

[0043] To improve the rigidity and stability of the linear guide 2, this embodiment designs the cross-section of the linear guide 2 as a triangle. The triangular cross-section has excellent bending and torsional resistance, and can maintain sufficient rigidity over long spans to prevent deformation caused by its own weight or external loads.

[0044] The three faces of the triangular guide rail provide a clear guiding reference for the moving component 8, with two inclined faces cooperating with the rollers 82 of the moving component 8, and the bottom face mainly bearing the load. This cross-sectional shape also facilitates machining and installation, ensuring manufacturing accuracy and assembly quality.

[0045] To optimize the kinematic performance of the entire cleaning equipment, this embodiment features a specially designed connection relationship for the guide rail system. One end of the linear guide rail 2 is slidably connected to the annular guide rail 1, allowing it to move smoothly along the annular guide rail 1 under the drive of the first driving device 4; the other end of the linear guide rail 2 is rotatably connected to the support 3, allowing the linear guide rail 2 to swing freely in the plane. The support 3 can be located at the center of the annular guide rail 1. This geometric layout ensures that the linear guide rail 2 maintains the correct posture during movement, providing a stable motion reference for the water pipe moving device 6. The entire guide rail system forms a precise polar coordinate motion mechanism, capable of efficiently covering all heat exchanger tube positions within the area of ​​the annular guide rail 1.

[0046] like Figure 1 and Figure 2As shown in this embodiment, a water pipe frame 7 is provided on the water pipe moving device, and the water pipe frame 7 is used to support the high-pressure water pipe 9.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
