Description

Technical Field

[0001] This utility model relates to the field of steel pipe rust removal technology, and in particular to a steel pipe rust removal device and rust removal system. Background Technology

[0002] Steel pipes, as a fundamental material in industrial production, are widely used in construction, petroleum, chemical, and machinery manufacturing industries. With the rapid development of modern industry, the requirements for steel pipe quality are becoming increasingly stringent. Steel pipe surface treatment technology has evolved from manual grinding and abrasive wheel grinding to automated grinding. Early surface treatment of steel pipes relied mainly on manual operation, resulting in low efficiency and inconsistent quality. Subsequently, semi-automated mechanical grinding improved efficiency. Today, with the advancement of industrial automation, steel pipe surface treatment technology is constantly innovating to meet the demands of high-precision, high-quality production.

[0003] In current steel pipe production processes, numerous scratches, oxide scale, loose rust, and oil stains often form on the surface of the steel pipes during manufacturing. These defects directly affect the finished product quality and subsequent performance. To ensure the quality of the finished steel pipes, sandblasting and rust removal are usually required. In existing technologies, rust removal of steel pipes primarily utilizes specialized equipment such as grinding machines. Operators control the grinding wheel to perform comprehensive grinding on the steel pipe surface to remove surface defects such as scratches, oxide scale, loose rust, and oil stains, improving the surface smoothness and flatness of the steel pipe, thereby ensuring that the steel pipe meets the required surface quality standards.

[0004] Although grinding by hand or with grinding wheel equipment can remove scratches, scale, rust, and oil stains from the surface of steel pipes, it can also reduce the thickness of the steel plate and affect the overall strength of the pipe. Utility Model Content

[0005] The main purpose of this utility model is to propose a steel pipe rust removal device and rust removal system, which aims to solve the technical problem that when using manual grinding or abrasive wheel grinding equipment to perform grinding operations, although it can remove scratches, oxide scale, floating rust and oil stains on the surface of steel pipes, the actual grinding process will cause the steel plate thickness of the steel pipe to become thinner, affecting the overall strength of the steel pipe.

[0052] This utility model proposes a steel pipe rust removal device and rust removal system.

[0053] Please see Figures 1 to 8 In one embodiment of this utility model, a steel pipe rust removal device 10 includes a sand storage tank 100, a position adjustment mechanism 300, and a steel pipe rust removal mechanism 400. The sand storage tank 100 has a sand storage space inside. The tank body of the sand storage tank 100 has a sand inlet 110, an air inlet 120, and a sand discharge hole 130 distributed at intervals. The sand discharge hole 130 is formed at the bottom of the sand storage tank 100. The air inlet 120 is connected to an air compressor 200 through an air pipe. The position adjustment mechanism 300 is installed at intervals on one side of the sand storage tank 100. The steel pipe rust removal mechanism 400 is installed on the side of the position adjustment mechanism 300 away from the sand storage tank 100. The steel pipe rust removal mechanism 400 is fitted with a steel pipe 500 to be rusted. The position adjustment mechanism 300 can drive the steel pipe rust removal mechanism 400 to strike the steel pipe 500 to be rusted.

[0054] Specifically, the sand storage tank 100 has spaced sand inlets 110, air inlets 120, and sand discharge holes 130 on its body. The sand inlets 110 are used to add abrasive for grinding into the sand storage tank 100. The air inlets 120 are located on the side wall of the tank body and are used to connect to an external air compressor 200. The sand discharge holes 130 are formed at the bottom of the sand storage tank 100 to facilitate the discharge of abrasive from the bottom. Position adjustment mechanisms 300 are spaced apart on one side of the sand storage tank 100, while steel pipe rust removal mechanisms 400 are installed on the side of the position adjustment mechanisms 300 away from the sand storage tank 100. Steel pipes 500 to be rusted can be fitted onto the steel pipe rust removal mechanisms 400. Driven by the position adjustment mechanisms 300, the steel pipe rust removal mechanisms 400 can perform uniform and precise rust removal operations on the steel pipes 500 to be rusted.

[0055] In the steel pipe rust removal device 10 of this embodiment, a sand storage tank 100 has a sand storage space for storing the abrasive material needed for grinding the steel pipe. The tank body of the sand storage tank 100 has spaced sand inlets 110, air inlets 120, and sand discharge holes 130. The sand inlets 110 are used to add abrasive material into the sand storage space. The air inlets 120 are connected to an air compressor 200 via an air pipe. After the air compressor 200 is started, it can deliver high-pressure gas into the sand storage tank 100, causing the abrasive material in the sand storage tank 100 to be ejected from the sand discharge holes 130 under air pressure. The sand discharge holes 130 are formed at the bottom of the sand storage tank 100, allowing the abrasive material to be discharged more smoothly under the combined action of gravity and air pressure, thus improving grinding efficiency.

[0056] Position adjustment mechanisms 300 are installed at intervals on one side of the sand storage tank 100 to adjust the position of the steel pipe rust removal mechanism 400, enabling it to be positioned at different parts of the steel pipe 500 to be rusted. A certain distance is maintained between the position adjustment mechanism 300 and the sand storage tank 100 to prevent sand from contaminating and abrading the position adjustment mechanism 300, thus extending the equipment's service life. The steel pipe rust removal mechanism 400 is installed on the side of the position adjustment mechanism 300 opposite to the sand storage tank 100. The steel pipe 500 to be rusted is fitted onto the steel pipe rust removal mechanism 400. Driven by the position adjustment mechanism 300, the steel pipe rust removal mechanism 400 can be precisely positioned and moved on the surface of the steel pipe, ensuring the uniformity and accuracy of the impact.

[0057] In the steel pipe rust removal process, the steel pipe 500 to be rusted is first placed on the steel pipe rust removal mechanism 400. Then, the air compressor 200 is started, and high-pressure gas enters the sand storage tank 100 through the air inlet 120, spraying the sand in the sand storage space out through the sand discharge hole 130. At the same time, the position adjustment mechanism 300 drives the steel pipe rust removal mechanism 400 to move along the surface of the steel pipe 500 to be rusted, so that the sand is evenly sprayed onto the surface of the steel pipe for rust removal. Compared with traditional manual grinding or abrasive wheel grinding, sandblasting has the advantages of being more uniform and controllable. It can accurately remove scratches, oxide scale, loose rust, and oil stains without over-grinding the steel pipe body. This effectively solves the technical problem that traditional grinding rust removal methods cause the steel pipe body to be over-grinded, resulting in thinner steel pipe walls and affecting the overall strength of the steel pipe.

[0058] In this embodiment, by setting up a sand storage tank 100, a position adjustment mechanism 300, and a steel pipe rust removal mechanism 400, a sand storage space is formed inside the sand storage tank 100 during use. The tank body of the sand storage tank 100 has spaced-apart sand inlets 110, air inlets 120, and sand discharge holes 130. The sand discharge holes 130 are formed at the bottom of the sand storage tank 100. The air inlets 120 are connected to an air compressor 200 via an air pipe. The position adjustment mechanism 300 is spaced-apart on one side of the sand storage tank 100, and the steel pipe rust removal mechanism 400 is installed at the position adjustment mechanism 300. The position adjustment mechanism 300 is positioned away from the sand storage tank 100. The steel pipe rust removal mechanism 400 is fitted with a steel pipe 500 to be rusted. The position adjustment mechanism 300 can drive the steel pipe rust removal mechanism 400 to strike the steel pipe 500 to be rusted. This utility model utilizes the set rail rust removal device to spray steel sand onto the steel pipe 500 to be rusted, thereby enabling the utility model to achieve the function of grinding and rust removal of the steel pipe 500 without the need for a grinding wheel, avoiding damage to the steel pipe body and ensuring the overall strength of the steel pipe.

[0059] In one embodiment, the position adjustment mechanism 300 includes a column 310, a drive assembly 320, and two guide assemblies 330. The column 310 is spaced apart and installed on one side of the sand storage tank 100. The top of the column 310 is provided with an installation position. The steel pipe rust removal mechanism 400 is slidably installed on both sides of the column 310 and extends away from the sand storage tank 100. The drive assembly 320 is installed in the installation position. The two drive ends of the drive assembly 320 are respectively located on both sides of the column 310 and are both located above the steel pipe rust removal mechanism 400. The two guide assemblies 330 are slidably installed on both sides of the column 310 and are connected to the two drive ends on the corresponding sides. The steel pipe rust removal mechanism 400 is slidably installed on the guide assembly 330. The drive assembly 320 can drive the guide assembly 330 on the corresponding side to move up and down along the column 310.

[0060] Specifically, the columns 310 are spaced apart and installed on one side of the sand storage tank 100 to form a stable support structure. The top of the columns 310 has a mounting position for installing the drive assembly 320. The steel pipe rust removal mechanism 400 is slidably installed on both sides of the columns 310, and extends away from the sand storage tank 100 to create a gap between the steel pipe rust removal mechanism 400 and the sand storage tank 100. This prevents the sand generated during grinding from interfering with the sand storage tank 100 and also facilitates the operator's observation and control of the rust removal process.

[0061] The drive assembly 320 is installed at the top of the column 310, with its two drive ends positioned on either side of the column 310, both above the steel pipe rust removal mechanism 400. This allows the drive assembly 320 to apply driving force to the steel pipe rust removal mechanism 400 from above, achieving precise control of the mechanism. Two guide assemblies 330 are slidably installed on either side of the column 310, each connected to a corresponding drive end. The steel pipe rust removal mechanism 400 is slidably installed on the guide assemblies 330, and the drive assembly 320 can drive the corresponding guide assembly 330 to move up and down along the column 310.

[0062] In actual use, when it is necessary to adjust the position of the steel pipe rust removal mechanism 400, the drive component 320 drives the guide components 330 on both sides to rise and fall along the column 310 through the two drive ends. Since the steel pipe rust removal mechanism 400 is installed on the guide component 330, the steel pipe rust removal mechanism 400 also rises and falls accordingly, thereby realizing the precise adjustment of the steel pipe rust removal position.

[0063] Furthermore, since the steel pipe rust removal mechanism 400 is slidably mounted on the guide assembly 330, it can also be adjusted in the horizontal direction, thereby increasing the flexibility of the steel pipe rust removal device 10 and enabling it to adapt to the rust removal needs of steel pipes of different specifications and shapes. Through the coordinated operation of the column 310, drive assembly 320, and guide assembly 330, the position adjustment mechanism 300 can achieve precise positioning of the steel pipe rust removal mechanism 400 in both vertical and horizontal directions, ensuring the accuracy and uniformity of the rust removal process.

[0064] In one embodiment, the guide assembly 330 includes a first guide rail 331, a mounting plate 332, a plurality of second sliding members 334, and a first drive member 335. The first guide rail 331 is vertically mounted on the column 310. The top of the mounting plate 332 is connected to the drive end on the corresponding side. The mounting plates 332 are spaced apart on one side of the column 310, and the side of the mounting plate 332 facing the column 310 is provided with a first sliding member 333 that slides with the guide rail. The plurality of second sliding members 334 are opposite to each other and spaced apart on the mounting plate 332 facing away from the column 310. On one side, an installation space for installing the steel pipe rust removal mechanism 400 is formed between all two pairs of opposing second sliding members 334, and a through hole 435 is formed on the mounting plate 332 corresponding to the position of the installation space. The first driving member 335 is installed on the side of the mounting plate 332 facing the column 310. The output shaft of the first driving member 335 rotatably passes through the through hole 435 and extends into the installation space. The output shaft of the first driving member 335 contacts the steel pipe rust removal mechanism 400 on the corresponding side and drives the steel pipe rust removal mechanism 400 on the corresponding side to slide along the installation space.

[0065] Specifically, the guide assembly 330 includes a first guide rail 331, a mounting plate 332, multiple second sliding members 334, and a first drive member 335. The first guide rail 331 is vertically mounted on the column 310, providing vertical sliding guidance for the mounting plate 332. The top of the mounting plate 332 is connected to the drive end on the corresponding side. Driven by the drive assembly 320, the mounting plate 332 can slide up and down along the first guide rail 331, realizing the vertical position adjustment of the steel pipe rust removal mechanism 400. The mounting plates 332 are spaced apart on one side of the column 310, and the side of the mounting plate 332 facing the column 310 is provided with a first sliding member 333 that slides with the guide rail. The first sliding member 333 slides with the first guide rail 331 to ensure that the mounting plate 332 remains stable during the lifting process and does not shake or tilt.

[0066] Multiple second sliding members 334 are installed in pairs, spaced apart, on the side of the mounting plate 332 away from the column 310. The spaces between all pairs of opposing second sliding members 334 form an installation space for the steel pipe rust removal mechanism 400. This allows the steel pipe rust removal mechanism 400 to slide horizontally, achieving rust removal on different parts of the steel pipe. A through hole 435 is formed on the mounting plate 332 corresponding to the installation space. A first driving member 335 is installed on the side of the mounting plate 332 facing the column 310. The output shaft of the first driving member 335 rotatably passes through the through hole 435 and extends into the installation space. The output shaft of the first driving member 335 contacts the corresponding side of the steel pipe rust removal mechanism 400 and drives the corresponding side of the steel pipe rust removal mechanism 400 to slide along the installation space.

[0067] In practical use, when the vertical position of the steel pipe rust removal mechanism 400 needs to be adjusted, the drive assembly 320 drives the mounting plate 332 to slide up and down along the first guide rail 331 via the drive end, thereby adjusting the height position of the steel pipe rust removal mechanism 400. When the horizontal position of the steel pipe rust removal mechanism 400 needs to be adjusted, the first drive component 335 drives the steel pipe rust removal mechanism 400 to slide within the installation space via the output shaft, achieving precise positioning and rust removal operations for different parts of the steel pipe.

[0068] In one embodiment, there are two first guide rails 331, which are distributed opposite to each other on both sides of the column 310, and there are at least two first sliding members 333, which are spaced apart and can be slidably clamped on the two first guide rails 331.

[0069] Specifically, the dual-rail structure offers better stability and load-bearing capacity compared to the single-rail structure, providing more robust support and more precise guidance for the mounting plate 332. The two first rails 331 are distributed opposite each other on both sides of the column 310, forming a stable guiding system that ensures smooth and accurate vertical movement of the mounting plate 332, preventing swaying or tilting.

[0070] The number of first sliding members 333 is at least two, and the at least two first sliding members 333 are spaced apart and can be slidably clamped onto the two first guide rails 331. The arrangement of multiple first sliding members 333 further enhances the connection stability between the mounting plate 332 and the first guide rails 331, preventing the mounting plate 332 from shifting or shaking during lifting. The first sliding members 333 are slidably clamped onto the first guide rails 331. Compared with the ordinary sliding connection method, the clamping connection method has better stability and load-bearing capacity, can withstand greater loads, and is suitable for rust removal operations on heavy steel pipes.

[0071] In actual use, when it is necessary to adjust the vertical position of the steel pipe rust removal mechanism 400, the drive assembly 320 drives the mounting plate 332 to slide up and down along the two first guide rails 331 via the drive end. Since the first sliding member 333 and the first guide rail 331 are connected by a clamping connection, the mounting plate 332 can remain stable during the lifting process and will not shake or tilt, thereby ensuring that the position adjustment of the steel pipe rust removal mechanism 400 is accurate and reliable.

[0072] The coordinated operation of the dual-guide-rail structure and multiple first sliding elements 333 not only improves the stability and load-bearing capacity of the connection between the column 310 and the mounting plate 332, but also enhances the accuracy and reliability of the position adjustment of the steel pipe rust removal mechanism 400. Especially when removing rust from large or heavy steel pipes, the combination of the dual-guide-rail structure and multiple first sliding elements 333 provides sufficient support and stability, ensuring the smooth progress of the rust removal operation.

[0073] In one embodiment, the drive assembly 320 includes two second drive members 321, two reducers 322, and two chains 323. The two second drive members 321 are both installed in the mounting position. The two reducers 322 are respectively installed on the output shafts of the two second drive members 321 and are both installed in the mounting position. The two reducers 322 are each connected to a chain 323, and each chain 323 is connected to the mounting plate 332 on the corresponding side. The second drive members 321 can drive the reducers 322 to drive the corresponding mounting plate 332 to slide along the first guide rail 331 through the chain 323 on the corresponding side, so that the steel pipe rust removal mechanism 400 rises and falls along the column 310.

[0074] Specifically, both second drive components 321 are mounted in the mounting position, and two reducers 322 are respectively mounted on the output shafts of the two second drive components 321, with both reducers 322 also mounted in the mounting position. This allows the second drive components 321 and reducers 322 to form a compact power unit, reducing the overall space occupied and facilitating installation and maintenance. Each of the two second drive components 321 is responsible for driving the reducer 322 on its corresponding side, achieving synchronous drive on both sides and ensuring that the mounting plate 332 remains horizontal during lifting and lowering, without tilting or wobbling.

[0075] Two reducers 322 are each connected to a chain 323, and each chain 323 is connected to a mounting plate 332 on its corresponding side. The chain 323 serves as the medium for power transmission, converting the rotational motion of the reducer 322 into the linear motion of the mounting plate 332, enabling the mounting plate 332 to slide smoothly along the first guide rail 331. The chain 323 drive offers advantages such as smooth transmission, high load-bearing capacity, and a fixed transmission ratio, making it particularly suitable for applications requiring precise position control, such as the steel pipe rust removal device 10. The connection of each chain 323 to the mounting plate 332 on its corresponding side forms a closed-loop transmission system, ensuring the reliability and stability of power transmission.

[0076] The second driving component 321 can drive the reducer 322 to slide the corresponding mounting plate 332 along the first guide rail 331 via the chain 323 on the corresponding side, so that the steel pipe rust removal mechanism 400 can be raised and lowered along the column 310. This allows the rotational motion of the second driving component 321 to be reduced by the reducer 322 and transmitted by the chain 323, ultimately transforming into precise linear motion of the mounting plate 332, achieving precise control of the position of the steel pipe rust removal mechanism 400.

[0077] In practical use, when the vertical position of the steel pipe rust removal mechanism 400 needs to be adjusted, the operator controls the operation of the two second drive components 321. The second drive components 321 drive the reducer 322 to rotate, and the reducer 322 drives the mounting plate 332 to slide up and down along the first guide rail 331 via the chain 323, thereby adjusting the height position of the steel pipe rust removal mechanism 400. Due to the adoption of a dual-side synchronous drive method, the mounting plate 332 can remain horizontal during the lifting and lowering process without tilting or swaying, thus ensuring that the position adjustment of the steel pipe rust removal mechanism 400 is accurate and reliable.

[0078] In one embodiment, the steel pipe rust removal mechanism 400 includes two crossbeams 410 and two rust removal components 430. Two mounting plates 332 slidably mount one crossbeam 410, and one end of each crossbeam 410 extends away from the sand storage tank 100 to form a grinding end. Each crossbeam 410 has a wire-passing hole 433. The two crossbeams 410 are respectively located on the inner and outer sides of the steel pipe 500 to be rusted, and each crossbeam 410 has a second guide rail 420 on the side facing the column 310. The rail 420 extends along the corresponding crossbeam 410 toward the corresponding rust removal end. Each rust removal component 430 is equipped with a rust removal component 430. All rust removal components 430 are positioned toward the steel pipe 500 to be rusted. Each rust removal component 430 is connected to the sand storage tank 100 through a sand discharge pipe 434 passing through the corresponding wire hole 433. The first driving component 335 can drive the guide rail to slide the corresponding crossbeam 410 so that the rust removal component 430 can approach or move away from the sand storage tank 100 and spray abrasive steel sand to strike the steel pipe 500 to be rusted.

[0079] Specifically, the steel pipe rust removal mechanism 400 includes two crossbeams 410 and two rust removal components 430. Two mounting plates 332 are each slidably mounted on a crossbeam 410, and one end of each crossbeam 410 extends away from the sand storage tank 100 to form a rust removal end. This connection method allows the crossbeams 410 to rise and fall with the mounting plates 332, achieving vertical position adjustment. Simultaneously, the crossbeams 410 can also slide on the mounting plates 332, achieving horizontal position adjustment, thus enabling the rust removal components 430 to be accurately positioned at the area requiring grinding.

[0080] Both crossbeams 410 have through holes 433, and the two crossbeams 410 are respectively located on the inner and outer sides of the steel pipe 500 to be derusted. The through holes 433 facilitate the passage of the sand discharge pipe 434 through the crossbeams 410, transporting the sand in the sand storage tank 100 to the derusting assembly 430. The two crossbeams 410 are respectively located on the inner and outer sides of the steel pipe 500 to be derusted, enabling the steel pipe derusting mechanism 400 to simultaneously derust both the inner and outer sides of the steel pipe, which not only improves the derusting efficiency but also ensures the comprehensiveness and uniformity of the derusting.

[0081] Each crossbeam 410 has a second guide rail 420 on the side facing the column 310, extending along the corresponding crossbeam 410 towards the corresponding rust-removing end. The second guide rail 420 provides sliding guidance for the rust-removing assembly 430, allowing the rust-removing assembly 430 to slide along the crossbeam 410, achieving rust removal by impact at different parts of the steel pipe. The second guide rail 420 extends along the corresponding crossbeam 410 towards the corresponding rust-removing end, ensuring that the rust-removing assembly 430 can slide to the rust-removing end of the crossbeam 410, achieving rust removal at the end of the steel pipe.

[0082] Each rust removal component 430 is installed, and all rust removal components 430 are positioned facing the steel pipe 500 to be rusted. Each rust removal component 430 is connected to the sand storage tank 100 through a sand discharge pipe 434 inserted into a corresponding wire hole 433. The rust removal component 430, as the part that actually performs the rust removal operation, is positioned facing the steel pipe 500 to ensure that the abrasive can be directly sprayed onto the surface of the steel pipe. Each rust removal component 430 is connected to the sand storage tank 100 through the sand discharge pipe 434, allowing the abrasive in the sand storage tank 100 to be transported to the rust removal component 430 through the sand discharge pipe 434, and then sprayed onto the surface of the steel pipe for polishing.

[0083] The first driving component 335 can drive the guide rail to slide the corresponding crossbeam 410, so that the rust removal component 430 can approach or move away from the sand storage tank 100 and spray abrasive gravel to strike the steel pipe 500 to be rusted. The first driving component 335 drives the crossbeam 410 to slide by driving the guide rail, thereby achieving precise control of the horizontal position of the rust removal component 430.

[0084] In one embodiment, the rust removal assembly 430 includes two mounting bases 431 and two sandblasting nozzles 432. The two mounting bases 431 are installed at intervals on the rust removal end, and a channel for the sand discharge pipe 434 to pass through is formed in the mounting base 431. Each mounting base 431 is equipped with a sandblasting nozzle 432, and each sandblasting nozzle 432 is arranged facing the steel pipe 500 to be rusted. Each sandblasting nozzle 432 is connected to the sand discharge pipe 434 that passes through the corresponding wire hole 433 and the channel in sequence.

[0085] Specifically, the rust removal assembly 430 adopts a dual sandblasting nozzle 432 structure, including two mounting seats 431 and two sandblasting nozzles 432. The two mounting seats 431 are installed at intervals on the rust removal end, allowing the two sandblasting nozzles 432 to be aimed at different parts of the steel pipe surface, achieving simultaneous rust removal over a wider area. A channel is formed within the mounting seat 431 for the sand discharge pipe 434 to pass through, facilitating the transport of sand from the sand storage tank 100 to the sandblasting nozzles 432. Each mounting seat 431 is equipped with one sandblasting nozzle 432, and each sandblasting nozzle 432 is positioned towards the steel pipe 500 to be rusted. The sandblasting nozzle 432 is the component that actually performs the sandblasting rust removal operation; its orientation towards the steel pipe 500 ensures that the sand is directly sprayed onto the steel pipe surface. Each sandblasting nozzle 432 is connected to a sand discharge pipe 434 that passes through the corresponding wire hole 433 and channel in sequence, so that the sand in the sand storage tank 100 can be transported to the sandblasting nozzle 432 through the sand discharge pipe 434 and then sprayed onto the surface of the steel pipe for rust removal.

[0086] The sand discharge pipe 434 passes through the wire hole 433 and the channel in sequence, connecting the sand storage tank 100 and the sandblasting nozzle 432 to form a complete sand conveying path. At the same time, because the sand discharge pipe 434 is protected and fixed by passing through the wire hole 433 and the channel, the shaking and deformation of the sand discharge pipe 434 under high pressure is reduced, which improves the stability and reliability of the entire system.

[0087] In one embodiment, there are two sand storage tanks 100, and each of the two sand storage tanks 100 is connected to a rust removal component 430 through a sand discharge pipe 434. Both sand storage tanks 100 are connected to an air compressor 200.

[0088] Specifically, the installation of two dual sand storage tanks 100 not only increases the sand storage capacity but also extends the continuous working time, reduces the frequency of downtime due to sand replacement, and improves work efficiency. Furthermore, the dual sand storage tanks 100 can store different types or sizes of sand separately, adapting to different rust removal needs and enhancing the flexibility and adaptability of the steel pipe rust removal device 10.

[0089] Both sand storage tanks 100 are connected to a rust removal component 430 via sand discharge pipes 434, ensuring that each rust removal component 430 has an independent sand supply source, preventing insufficient or uneven sand supply from affecting the grinding effect. At the same time, the layout of the sand discharge pipes 434 is simplified, reducing their length and bends, lowering the resistance and likelihood of blockage during sand transport, and improving the stability and reliability of sand transport.

[0090] Both sand storage tanks 100 are connected to an air compressor 200. The air compressor 200, acting as a power source, supplies high-pressure gas to the sand storage tanks 100, blowing the sand to the rust removal assembly 430 for rust removal. The connection of both sand storage tanks 100 to the air compressor 200 ensures that both tanks receive sufficient air pressure for stable sand transport. The air compressor 200 can be connected to the air inlets 120 of both sand storage tanks 100 via individual air pipes, or via a branch of a single air pipe. Regardless of the connection method, it ensures that both sand storage tanks 100 receive equal air pressure, achieving balanced sand transport.

[0091] In one embodiment, the steel pipe rust removal device 10 further includes a protective cover 600, which covers the outer periphery of the steel pipe rust removal mechanism 400.

[0092] Specifically, during the rust removal process of steel pipes, the collision between the high-speed blasted abrasive and the surface of the steel pipe generates a large amount of dust and splashes. Without proper protective measures, this dust and splashes will disperse into the surrounding environment, not only polluting the working environment but also potentially posing a health hazard to the operators. At the same time, the high-speed moving rust removal component 430 also poses certain safety risks.

[0093] A protective cover 600 is installed around the outer perimeter of the steel pipe rust removal mechanism 400, enclosing the entire rust removal area and forming a relatively enclosed space. This structural arrangement confines dust and splashes generated during the rust removal process within the protective cover 600, preventing them from spreading into the surrounding environment and effectively reducing environmental pollution. Simultaneously, the protective cover 600 also prevents the high-speed moving rust removal component 430 from contacting the outside environment, preventing operators from accidentally touching the rust removal component 430 and improving operational safety.

[0094] Based on the same technical concept, in a second aspect, this utility model also proposes a steel pipe rust removal system, including a steel pipe rust removal device 10 and two support mechanisms 20. The two support mechanisms 20 are spaced apart below the steel pipe rust removal mechanism 400, and both support mechanisms 20 are set on the side of the column 310 away from the sand storage tank 100. The support mechanism 20 includes a support base 21 and two rollers 22. The top of the support base 21 forms two spaced placement positions, and a roller 22 is rotatably installed at each of the two placement positions. A placement groove 23 for placing the steel pipe 500 to be rusted is formed between the two rollers 22 on the same support base 21.

[0095] Specifically, the steel pipe rust removal system includes two support mechanisms 20, which are spaced apart below the steel pipe rust removal mechanism 400, and both support mechanisms 20 are located on the side of the column 310 away from the sand storage tank 100. This allows the two support mechanisms 20 to support both ends of the steel pipe, providing stable support. The location of the support mechanisms 20 on the side of the column 310 away from the sand storage tank 100 facilitates loading, unloading, and adjustment of the steel pipe by operators from this side, improving operational convenience.

[0096] The support mechanism 20 includes a support base 21 and two rollers 22. The support base 21 serves as the foundation of the entire support mechanism 20, providing a stable mounting platform for the rollers 22. The top of the support base 21 has two spaced-apart placement positions for mounting the rollers 22. The spaced-apart arrangement ensures that there is sufficient space between the rollers 22 to form a placement groove 23.

[0097] Two rollers 22 are rotatably mounted at each of the two placement positions. These rollers 22 can rotate freely on their own axes, ensuring the steel pipe is not only stably supported within the placement groove 23 but also rotated as needed, facilitating grinding of different parts of the steel pipe. A placement groove 23 is formed between the two rollers 22 on the same support base 21 for placing the steel pipe 500 to be rusted. The depth and width of the placement groove 23 are typically designed according to the specifications of the steel pipe 500 to ensure stable placement within the groove.

[0098] Of course, it can be further explained that the support mechanism 20 in this embodiment also includes a third driving member 24. The third driving member 24 is installed on one side of the support base 21, and the drive shaft of the third driving member 24 is connected to one of the rollers 22 to drive the rollers 22 to rotate, thereby enabling the rollers 22 to drive the steel pipe 500 to be derusted to rotate. In this embodiment, the first driving member 335, the second driving member 321, and the third driving member 24 are all preferably motors.

[0099] In actual use, the steel pipe 500 to be derusted is first placed in the placement slots 23 of the two support mechanisms 20, with each end of the pipe supported by one of the two support mechanisms 20. Then, the vertical position of the crossbeam 410 is adjusted by the drive component 320 so that the derusting component 430 is facing the part that needs derusting. After the air compressor 200 is started, high-pressure gas enters the sand storage tank 100 through the air inlet 120, and the sand in the sand storage tank 100 is transported to the derusting component 430 through the sand discharge pipe 434. The derusting component 430 sprays the sand onto the surface of the steel pipe 500 to remove rust. During the derusting process, if it is necessary to derust other parts of the steel pipe, the angle of the steel pipe can be changed by rotating the roller 22 so that the part to be derusted faces the derusting component 430.

[0100] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
