Description

Technical Field

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

[0002] As a core component of refrigeration and heat exchange systems, the cleanliness of the copper tubes inside the condenser directly affects heat exchange efficiency and equipment lifespan. Over time, scale, rust, and microbial deposits easily accumulate on the inner walls of the copper tubes. If not cleaned promptly, this can lead to increased thermal resistance, higher energy consumption, and even equipment failure. Therefore, condenser tube cleaning devices are crucial for ensuring stable system operation.

[0003] However, traditional condenser tube cleaning devices, especially rotary brush head cleaning devices, often use an integrated fixed structure or a complex bolt connection method for the brush plates. When the brush plates are damaged due to long-term friction, such as brush bristle wear or plate deformation, multiple connecting parts need to be disassembled to complete the replacement. This not only involves complicated operation steps but also requires the assistance of professional tools, resulting in a long replacement process.

[0004] For example, in the condenser cleaning operation of a food processing plant, the brush bristles of the traditional brush plate fixed structure became flattened after cleaning multiple machines, making it unable to effectively remove dirt. The maintenance personnel had to first remove the outer shell of the device, loosen the connecting bolts between the drive shaft and the brush plate, then separate the brush plate from the fixed components, replace the new brush plate, and then reassemble all the components in reverse. The whole process took a long time. Utility Model Content

[0005] This utility model discloses a condenser tube cleaning device, which aims to solve the technical problem that traditional condenser tube cleaning devices, especially rotary brush head cleaning devices, often use an integrated fixed structure or a complex bolt connection method for the brush plate. When the brush plate is damaged due to long-term friction, such as brush bristle wear or plate deformation, multiple connecting parts need to be disassembled to complete the replacement. This not only involves cumbersome operation steps but also requires professional tools, resulting in a long replacement process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A condenser tube cleaning device includes a housing, an inner wall of which is connected to a connecting pipe, an inner wall of which is fitted with a flexible shaft, and a water flow chamber between the inner wall of the connecting pipe and the outer wall of the flexible shaft. The housing, connecting pipe, and flexible shaft are all made of deformable material. The device further includes: a fixing mechanism: the fixing mechanism includes a fixing post mounted on one side of the outer wall of the flexible shaft, a brush plate sleeved on the outer wall of the fixing post, multiple locking posts connected to the outer wall of the brush plate near the flexible shaft, a third connecting plate connected to the outer wall of the multiple locking posts away from the brush plate, the third connecting plate connected to the outer wall of the fixing post, a second connecting plate connected to the outer wall of the brush plate away from the third connecting plate, a guide head sleeved on the outer wall of the second connecting plate, four springs evenly spaced on the outer wall of the second connecting plate, a locking block connected to one side of the outer wall of each spring, the locking block penetrating the outer wall of the guide head; and a cleaning mechanism: the cleaning mechanism is located on a support plate on the outer wall of the connecting pipe.

[0008] In this design, the fixing mechanism includes a fixing post installed on the outer wall of one side of the flexible shaft. The fixing post provides a stable mounting base for subsequent components. A brush plate is sleeved on the outer wall of the fixing post. Multiple locking posts are connected to the outer wall of the brush plate near the flexible shaft. A third connecting plate is connected to the outer wall of the multiple locking posts away from the brush plate, thus preventing the brush plate from falling off or shaking during high-speed rotation cleaning. The third connecting plate is connected to the outer wall of the fixing post, thus achieving a stable connection between the brush plate and the fixing post through the locking posts and the third connecting plate. A second connecting plate is connected to the outer wall of the brush plate away from the third connecting plate. The second connecting plate mainly provides installation positions for its internal components. A guide head is sleeved on the outer wall of the second connecting plate. Four springs are evenly installed on the outer wall of the second connecting plate, providing elasticity to the locking blocks. A locking block is connected to one side of the outer wall of the spring. Under the action of the spring, the locking block can tightly engage in the corresponding slot of the guide head, achieving a stable connection between the guide head and the second connecting plate, and facilitating the later disassembly and replacement of the guide head. The locking block penetrates through the outer wall of the guide head, ensuring the effectiveness of the engagement connection.

[0009] In a preferred embodiment, the cleaning mechanism includes a support plate connected to the outer wall of the connecting pipe. A plurality of equally spaced nozzles are connected to the outer wall of the support plate on the side away from the connecting pipe. The support plate has a water outlet cavity inside. The connecting pipe has a plurality of equally spaced water outlet holes at one end near the support plate. The plurality of water outlet holes correspond one-to-one with the slots inside the water outlet cavity.

[0010] In this solution, the cleaning mechanism includes a support plate connected to the outer wall of the connecting pipe. The support plate provides a stable mounting platform for the nozzles and is welded to the connecting pipe. It can withstand the impact of water flow during cleaning without deformation. Multiple evenly spaced nozzles are connected to the outer wall of the support plate on the side away from the connecting pipe. These evenly spaced nozzles cover a larger cleaning area, ensuring that all areas inside the pipe are rinsed by the water flow. The support plate has an outlet chamber inside, which serves as a temporary storage and diversion space for the water flow within the support plate, while also maintaining a stable pressure before the water enters each nozzle. To prevent uneven water flow from the nozzles due to pressure fluctuations, the connecting pipe has multiple evenly spaced water outlets at one end near the support plate. These outlets serve as channels for water to flow from the connecting pipe into the water outlet chamber. The evenly spaced design ensures that water flows evenly into the water outlet chamber, preventing localized high or low water pressure. Each outlet corresponds to a slot inside the water outlet chamber, preventing water leakage and pressure loss. This also ensures a uniform distribution of water flow into the water outlet chamber, providing stable water volume and pressure support for each nozzle, thereby guaranteeing consistent rinsing performance and improving overall cleaning effectiveness.

[0011] As described above, a condenser tube cleaning device includes a housing, an inner wall of which is connected to a connecting pipe, an inner wall of which is provided with a flexible shaft, and a water flow chamber between the inner wall of the connecting pipe and the outer wall of the flexible shaft. The housing, connecting pipe, and flexible shaft are all made of deformable material. The device also includes: a fixing mechanism: the fixing mechanism includes a fixing post installed on one side of the outer wall of the flexible shaft, a brush plate sleeved on the outer wall of the fixing post, multiple locking posts connected to the outer wall of the brush plate near the flexible shaft, a third connecting plate connected to the outer wall of the multiple locking posts away from the brush plate, the third connecting plate connected to the outer wall of the fixing post, a second connecting plate connected to the outer wall of the brush plate away from the third connecting plate, a guide head sleeved on the outer wall of the second connecting plate, four springs equally spaced on the outer wall of the second connecting plate, a locking block connected to one side of the outer wall of each spring, and the locking block penetrating the outer wall of the guide head; and a cleaning mechanism: the cleaning mechanism is located on a support plate on the outer wall of the connecting pipe. The condenser tube cleaning device provided by this utility model has the technical advantages of facilitating quick replacement of damaged brush plates, reducing downtime impact, and cleaning residue in the gaps between brush bristles in real time.

[0019] The condenser tube cleaning device disclosed in this utility model is mainly applied to traditional condenser tube cleaning devices, especially rotary brush head cleaning devices. The brush plates of these devices often adopt an integrated fixed structure or a complex bolt connection method. When the brush plates are damaged due to long-term friction, such as brush bristle wear or plate deformation, multiple connecting parts need to be disassembled to complete the replacement. This not only involves cumbersome operation steps but also requires the assistance of professional tools, resulting in a long replacement process.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5A condenser tube cleaning device includes a housing 1, with a connecting pipe 19 connected to the inner wall of the housing 1. A flexible shaft 7 is installed on the inner wall of the connecting pipe 19, and a water flow chamber is provided between the inner wall of the connecting pipe 19 and the outer wall of the flexible shaft 7. The housing 1, the connecting pipe 19, and the flexible shaft 7 are all made of deformable material. The device also includes a fixing mechanism: the fixing mechanism includes a fixing post 8 installed on one side of the outer wall of the flexible shaft 7, a brush plate 9 sleeved on the outer wall of the fixing post 8, and multiple locking posts 12 connected to the outer wall of the brush plate 9 near the flexible shaft 7. A third connecting plate 15 is connected to the outer wall of the brush plate 9 on the side away from the third connecting plate 15. The third connecting plate 15 is connected to the outer wall of the fixed column 8. A second connecting plate 13 is connected to the outer wall of the brush plate 9 on the side away from the third connecting plate 15. A guide head 5 is sleeved on the outer wall of the second connecting plate 13. Four springs 21 are installed at equal intervals on the outer wall of the second connecting plate 13. A locking block 22 is connected to one side of the outer wall of the spring 21. The locking block 22 passes through the outer wall of the guide head 5. Cleaning mechanism: The cleaning mechanism is located on the support plate 4 on the outer wall of the connecting tube 19.

[0021] The fixing mechanism includes a fixing post 8 installed on the outer wall of one side of the flexible shaft 7. The fixing post 8 provides a stable mounting base for subsequent components. A brush plate 9 is sleeved on the outer wall of the fixing post 8. Multiple locking posts 12 are connected to the outer wall of the brush plate 9 near the flexible shaft 7. A third connecting plate 15 is connected to the outer wall of the multiple locking posts 12 away from the brush plate 9. This prevents the brush plate 9 from falling off or shaking during high-speed rotation cleaning. The third connecting plate 15 is connected to the outer wall of the fixing post 8, thus achieving a stable connection between the brush plate 9 and the fixing post 8 via the locking posts 12 and the third connecting plate 15. The outer wall is connected to a second connecting plate 13, which is mainly used to provide an installation position for its internal components. A guide head 5 is sleeved on the outer wall of the second connecting plate 13. Four springs 21 are installed at equal intervals on the outer wall of the second connecting plate 13. The springs 21 are used to provide elastic force for the locking block 22. A locking block 22 is connected to one side of the outer wall of the spring 21. Under the action of the spring 21, the locking block 22 can be tightly locked in the corresponding slot of the guide head 5, realizing a stable connection between the guide head 5 and the second connecting plate 13. At the same time, it is convenient to disassemble and replace the guide head 5 later. The locking block 22 penetrates the outer wall of the guide head 5 to ensure the effectiveness of the locking connection.

[0022] The outer wall of the brush plate 9 is connected with multiple fixing plates 10 at equal intervals. The outer wall of the fixing plate 10 away from the brush plate 9 is connected with multiple bristles 11. The length of the bristles 11 is slightly larger than the inner diameter of the condenser tube. The fixing plates 10 and the brush plate 9 are made by an integral molding process. The length of a single bristle 11 is slightly larger than the inner diameter of the condenser tube. During cleaning, it can closely fit the inner wall of the condenser tube and effectively remove the scale on the inner wall of the tube through the friction generated by rotation.

[0023] Specifically, a connecting post 14 is connected to one side of the outer wall of the guide head 5. The outer wall of the connecting post 14 away from the guide head 5 is fitted inside the fixed post 8. The guide head 5 has a conical head structure, and the front end of the guide head 5 is a smooth cone shape. When the device is inserted into the condenser tube, it can play a guiding role and reduce the resistance when entering.

[0024] Specifically, a rotating plate 18 is connected to one side of the outer wall of the outer casing 1, and a first connecting plate 3 is sleeved on the outer wall of the rotating plate 18. The inner wall of the first connecting plate 3 is connected to the outer wall of the connecting pipe 19. The rotating plate 18 is rotatably connected inside the first connecting plate 3, and the inner wall of the first connecting plate 3 is connected to the outer wall of the connecting pipe 19. The connecting pipe 19 is a channel for fluid or power transmission.

[0025] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the cleaning mechanism includes a support plate 4 connected to the outer wall of the connecting pipe 19. The outer wall of the support plate 4 away from the connecting pipe 19 is connected to a plurality of equally spaced nozzles 16. The support plate 4 has a water outlet cavity 20 inside. The end of the connecting pipe 19 near the support plate 4 has a plurality of equally spaced water outlet holes 17. The plurality of water outlet holes 17 correspond one-to-one with the slots inside the water outlet cavity 20.

[0026] The cleaning mechanism includes a support plate 4 connected to the outer wall of the connecting pipe 19. The support plate 4 provides a stable mounting platform for the nozzles 16. It is connected to the connecting pipe 19 by welding and can withstand the impact of water flow during cleaning without deformation. Multiple equally spaced nozzles 16 are connected to the outer wall of the support plate 4 away from the connecting pipe 19. These equally spaced nozzles 16 can cover a larger cleaning area, ensuring that all areas inside the pipe are rinsed by the water flow. The support plate 4 has a water outlet chamber 20 inside. The water outlet chamber 20 is a temporary storage and diversion space for the water flow within the support plate 4, and it also maintains a stable pressure before the water flows into each nozzle 16, preventing... Due to pressure fluctuations causing uneven water output from the nozzles 16, the connecting pipe 19 has multiple equally spaced water outlet holes 17 at one end near the support plate 4. The water outlet holes 17 are channels through which the connecting pipe 19 delivers water to the water outlet chamber 20. The equally spaced design allows water to enter the water outlet chamber 20 evenly, preventing local water pressure from being too high or too low. The multiple water outlet holes 17 correspond one-to-one with the slots inside the water outlet chamber 20, avoiding water leakage and pressure loss. At the same time, it ensures that the water flow entering the water outlet chamber 20 is evenly distributed, providing stable water volume and water pressure support for each nozzle 16, thereby ensuring consistent rinsing effect of each nozzle 16 and improving the overall cleaning effect.

[0027] The axis of the nozzle 16 is at a 30-degree angle to the rotation direction of the brush plate 9, which allows the water flow sprayed from the nozzle 16 to better match the trajectory of the brush plate 9 during rotation. The water flow can not only accurately wash away the dirt remaining on the pipe wall after the brush plate 9 has cleaned it, but also push the dirt out of the pipe along the direction of the centrifugal force generated by the rotation of the brush plate 9, reducing the retention time of dirt in the pipe.

[0028] Reference Figure 1 and Figure 3 In a preferred embodiment, a housing 6 is connected to one side of the outer wall of the outer casing 1. A drive motor and a water pump are provided inside the housing 6. The output end of the drive motor is connected to one side of the outer wall of the flexible shaft 7. The output end of the water pump is connected to a water inlet pipe 2. The outer wall of the water inlet pipe 2 away from the housing 6 is connected to the top outer wall of the outer casing 1.

[0029] The outer wall of the outer casing 1 is connected to the housing 6. The outer casing 1 is used to effectively protect the internal components such as the connecting pipe 19. At the same time, the housing 6 provides a safe and closed installation environment for the drive motor and the water pump. The drive motor and the water pump are located inside the housing 6. The drive motor is the power core of the entire device and can output stable torque and speed to provide sufficient power for the rotation of the brush plate 9. The water pump is responsible for drawing water for cleaning and providing water flow to the nozzle 16 of the cleaning mechanism. The two work together to ensure the normal operation of the cleaning operation of the device.

[0030] Working Principle: In use, first start the drive motor inside the housing 6. The output shaft directly drives the flexible shaft 7 to rotate. The flexible shaft 7 has good flexibility and can adapt to the curved structure of the condenser tubes, ensuring that the brush plate 9 can penetrate deep into the pipes for cleaning. The flexible shaft 7 drives the fixed column 8 to rotate synchronously. The fixed column 8 transmits torque to the brush plate 9 through the third connecting plate 15 and the clamping column 12, causing the brush plate 9 to rotate at a set speed. At this time, bristles 11 are evenly distributed on the fixed plate 10 on the outer wall of the brush plate 9. The length of the bristles 11 is slightly larger than the inner diameter of the condenser tube, ensuring full contact with the tube wall. The friction generated by the high-speed rotating bristles 11 effectively removes scale, rust, and biofilm from the tube wall. Then, start the water pump and deliver water through the inlet pipe 2 to the connecting pipe 19 inside the housing 1. This achieves the effect of water flowing through the water chamber between the inner wall of the connecting pipe 19 and the outer wall of the flexible shaft 7, and entering the outlet chamber 20 of the support plate 4 through the outlet hole 17. The cavity 20 evenly distributes water flow to each nozzle 16. The nozzle 16 sprays high-pressure water at a 30-degree angle onto the pipe wall, which, in conjunction with the rotation direction of the brush plate 9, cleans the residue in the gaps between the bristles 11 in real time. The guide head 5 adopts a conical structure, which guides the device when it enters the pipe and reduces insertion resistance. When the brush plate 9 is worn and needs to be replaced, simply press the four locking blocks 22 on the outer wall of the second connecting plate 13 and disengage the four locking blocks 22 from the outer wall of the guide head 5 to quickly remove the brush plate 9. At this time, the new brush plate 9 is quickly positioned with the fixing post 8 through the locking post 12 and the third connecting plate 15. Then, by pressing the four locking blocks 22 on the outer wall of the second connecting plate 13, the locking blocks 22 enter the interior of the second connecting plate 13 and squeeze the spring 21. Then, the connecting post 14, with the guide head 5, is inserted into the interior of the fixing post 8. At this time, the elastic force of the spring 21 pushes out the locking blocks 22 connected to it and locks them into the outer wall of the guide head 5, thereby achieving quick installation and fixation.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
