Description

Technical Field

[0001] This utility model relates to the technical field of air compressor scale removal tools, and in particular to a scale removal tool for air compressor cooling systems. Background Technology

[0002] Air compressors, as core power equipment in the industrial field, are widely used in industries such as chemical, mining, and machinery manufacturing. The cooling system is a key component to ensure the stable operation of the air compressor, and its working efficiency directly affects the core performance indicators of the air compressor, such as exhaust temperature and compression ratio. However, after long-term use, calcium and magnesium ions and impurities in the water are prone to deposit on the surface of the equipment to form scale, and traditional cleaning tools and methods have obvious shortcomings.

[0003] Currently, scale removal from air compressor cooling systems mainly employs methods such as chemical cleaning, high-pressure water jet cleaning, and mechanical scraping. While chemical cleaning can effectively dissolve scale, the highly corrosive agents can easily damage the equipment, and wastewater treatment is costly and polluting. High-pressure water jet cleaning requires sophisticated equipment, making it difficult to penetrate complex pipelines, and the cleaning effect is greatly affected by water pressure and angle. Traditional mechanical scraping tools have a simple structure, and the rigid spindle cannot adapt to curved pipes. The fixed-angle scraper cannot conform to the special structures of the cooler, such as the curved tube sheet and wavy flow channel, easily creating dead corners during cleaning, resulting in scale residue. Furthermore, repeated disassembly of pipes for cleaning is not only cumbersome but may also lead to problems such as decreased equipment sealing.

[0004] Therefore, we propose a tool for cleaning scale from air compressor cooling systems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tool for cleaning scale from air compressor cooling systems.

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

[0007] A scale removal tool for an air compressor cooling system includes a main body and a cooling pipe. A hollow flexible shaft is fixedly connected to one end of the main body. A spring steel core is installed inside the hollow flexible shaft. A universal joint is fixedly connected to the end of the hollow flexible shaft away from the main body. A secondary shaft is connected to the end of the universal joint. The secondary shaft assembly is rigidly connected to the hollow flexible shaft through the universal joint. A fan-shaped scraper is installed at the end of the secondary shaft.

[0008] As a further improvement of this utility model, the secondary shaft is provided with several on the end of the universal joint.

[0009] As a further improvement of this utility model: the fan-shaped scraper is adjusted by a secondary shaft, and its blade angle adjustment range is 0° - 45°.

[0010] As a further embodiment of this utility model: an electric motor is installed inside the main body at one end near the cooling pipe, the output end of the electric motor is connected to a hollow flexible shaft, and a control switch is installed on the upper side of the main body, the control switch being electrically connected to the electric motor.

[0011] As a further improvement of this utility model: a grip groove is provided at the end of the main body away from the cooling pipe, and anti-slip texture is provided inside the grip groove.

[0012] As a further improvement of this utility model, the hollow flexible shaft can be bent at an angle ranging from 30° to 60°.

[0013] Compared with the prior art, this utility model provides a tool for cleaning scale from an air compressor cooling system, which has the following beneficial effects:

[0014] This invention utilizes a hollow flexible shaft connected to a universal joint, allowing the cleaning tool to move freely through the complex piping of the cooling system. When encountering bends, the spring steel core provides flexible support to adjust the bending of the main shaft, ensuring that the secondary shaft remains perpendicular to the pipe wall. This allows the fan-shaped scraper to continuously adhere to the pipe wall for effective scraping, enabling cleaning of bends and improving the practicality of the device.

[0015] In this invention, when the main shaft is driven to rotate by an electric motor, the secondary shaft opens due to centrifugal force and forms contact pressure with the pipe wall. The spring steel core absorbs the impact energy through elastic deformation, preventing the scraper from damaging the pipe wall due to excessive pressure. In narrow areas, centrifugal force causes the scraper to automatically adjust its angle and maintain a constant scraping force, thereby improving cleaning efficiency while reducing damage to the cooling pipe.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A tool for cleaning scale from an air compressor cooling system, such as... Figures 1-4 As shown, the device includes a main body 1 and a cooling pipe 2. A hollow flexible shaft 3 is fixedly connected to one end of the main body 1. A spring steel core 4 is installed inside the hollow flexible shaft 3. A universal joint 5 is fixedly connected to the end of the hollow flexible shaft 3 away from the main body 1. A secondary shaft 6 is connected to the end of the universal joint 5. The secondary shaft 6 assembly is rigidly connected to the hollow flexible shaft 3 through the universal joint 5. A fan-shaped scraper 7 is installed at the end of the secondary shaft 6. The axial connection between the hollow flexible shaft 3 and the universal joint 5 allows the cleaning tool to move freely through the complex pipes of the cooling system. When encountering a bend, the spring steel core 4 provides flexible support to bend and adjust the main shaft, so that the secondary shaft 6 always remains perpendicular to the pipe wall. This allows the fan-shaped scraper 7 to continuously adhere to the pipe wall for effective scraping, achieving cleaning work on bends and improving the practicality of the device.

[0025] like Figures 1-3 As shown, several secondary shafts 6 are provided on the end of the universal joint 5. By providing multiple sets of secondary shafts 6, when cleaning the inner wall of the cooling pipe 2, the scale on the inner wall of the pipe can be scraped off from different directions at the same time, thereby improving the cleaning efficiency.

[0026] like Figures 1-3As shown, the fan-shaped scraper 7 is adjusted via the secondary shaft 6, and its blade angle adjustment range is 0° - 45°. The angle can be adjusted via the fan-shaped scraper 7. When cleaning the pipes of the cooler, the angle of the fan-shaped scraper 7 can be adjusted to a suitable angle to ensure that the blade is in close contact with the complex surface and improve the cleaning coverage.

[0027] like Figures 1-2 As shown, an electric motor 8 is installed inside the main body 1 near the cooling pipe 2. The output end of the electric motor 8 is connected to the hollow flexible shaft 3. A control switch 9 is installed on the upper side of the main body 1. The control switch is electrically connected to the electric motor 8. Through the control switch 9 and the electric motor 8, the operator can start and stop the motor by simply pressing a button. In case of an emergency during the cleaning process, the operator can quickly press the control switch 9 to stop the motor, avoiding damage to tools or further damage to the pipes caused by continuous operation, which greatly improves the convenience and safety of operation.

[0028] like Figures 1-2 As shown, a handle groove 10 is provided at the end of the main body 1 away from the cooling pipe 2. Anti-slip textures 11 are formed inside the handle groove 10. The handle groove 10 at the end of the main body 1 away from the cooling pipe 2 conforms to ergonomic design, fits the shape of the palm, and effectively reduces fatigue caused by prolonged tool holding. The anti-slip textures 11 inside the handle groove 10 increase the friction between the palm and the handle, ensuring a stable grip on the tool during cleaning and preventing accidental slippage. Figures 1-4 As shown, the hollow flexible shaft 3 can be bent at an angle of 30° - 60°. The hollow flexible shaft 3 can be bent at a certain angle, which allows it to easily pass through some complex and winding pipelines, thus improving its practicality.

[0029] Working principle: During use, the operator adjusts the blade angle of the fan-shaped scraper 7 to a suitable position according to the pipe diameter, curvature, and scale condition of the cooling pipe 2 through the adjustment mechanism. Holding the handle groove 10 of the main body 1, the operator inserts the hollow flexible shaft 3 and the auxiliary shaft 6 assembly into the cooling pipe 2. Upon startup, pressing the control switch 9 on the top of the main body 1 activates the electric motor 8. The output of the electric motor 8 drives the hollow flexible shaft 3 to rotate. Because the spring steel core 4 inside the hollow flexible shaft 3 provides support and resilience, it can flexibly adapt to the curvature of the pipe when encountering a curved section, ensuring stable power transmission. Multiple auxiliary shafts 6 are circumferentially positioned at the ends of the universal joint 5. The distribution of the scraper allows for synchronous scraping of the inner wall of the pipe in all directions during the rotation of the main shaft. The fan-shaped scraper 7, with its adjustable blade angle, can closely fit the complex structure of the cooler, such as the arc-shaped tube plate and the wavy flow channel, and scrape the scale from different directions. During use, the operator can adjust the speed of the electric motor 8 through the control switch 9, thereby adjusting the rotation speed of the hollow flexible shaft 3 and the secondary shaft 6 assembly to adapt to scale of different thicknesses and hardnesses. The anti-slip texture 11 inside the handle groove 10 ensures that the tool is always firmly held. After cleaning, press the control switch 9 again to turn off the electric motor 8 and remove the tool from the cooling pipe 2 to complete the scale cleaning work.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
