Description

Technical Field

[0001] This utility model belongs to the field of steel pipe rust removal technology, and more specifically, it relates to an environmentally friendly online steel pipe outer surface rust removal device. Background Technology

[0002] In steel pipe manufacturing enterprises, due to factors such as water pressure testing, excessive air humidity, and rain, the outer surface of qualified steel pipes is prone to corrosion after production. Rust not only affects the surface quality of the product, but over time it also significantly impacts its performance.

[0003] Currently, most rust removal equipment on the market includes sandblasting, shot blasting, and handheld rust removal machines. These are all offline rust removal methods, and there are few online rust removal devices for large steel pipes. Manufacturing companies currently mainly use manual brushing or offline rust removal for external surface rust removal. This not only results in high labor costs and low efficiency, but the use of rust removal equipment also generates smoke and noise, causing significant pollution to workers' health and the work environment. Furthermore, offline rust removal increases labor, equipment, and time costs associated with manual hoisting and handling, especially time costs, which greatly increases the pressure on companies to meet contract delivery deadlines. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly online steel pipe surface rust removal device that can continuously grind and remove rust from steel pipes without manual operation, thereby reducing labor costs and improving the rust removal efficiency of steel pipes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an environmentally friendly online rust removal device for the outer surface of steel pipes, comprising:

[0006] The transmission mechanism includes two sets of power components arranged at intervals along the transmission direction of the steel pipe. Each power component includes two roller motors. The output shafts of the two roller motors are coaxially arranged and at an angle to the transmission direction of the steel pipe. The drive shafts of the roller motors are connected to spherical rollers. The two sets of spherical rollers rotate under the drive of the corresponding roller motors to drive the steel pipe to be derusted to rotate and be transmitted axially.

[0007] The rust removal mechanism includes a rust removal frame disposed between the two power components. Two grinding shafts are symmetrically arranged on the upper end face of the rust removal frame. Grinding steel brushes are mounted on the grinding shafts. The two grinding steel brushes are respectively arranged on both sides of the steel pipe transmission direction. A speed-regulating motor is disposed below the rust removal frame. The output shaft of the speed-regulating motor is connected to the two grinding shafts. By driving the two grinding steel brushes to rotate synchronously in opposite directions, the outer surface of the steel pipe to be rusted is ground.

[0008] The dust removal mechanism includes a dustproof box and a dust collection box. The dustproof box is installed outside the rust removal frame, and the dust collection box is located on one side of the dustproof box. A dust collection pipe is connected between the dust collection box and the dustproof box. A blower is installed on the dust collection pipe, and the blower generates an airflow from the dustproof box to the dust collection box within the dust collection pipe.

[0009] In one possible implementation, bearing seats are respectively provided on the left and right sides of the upper end face of the rust removal frame, and the two ends of the grinding shaft are rotatably connected to the bearing seats on the same side. A driven pulley is provided on the grinding shaft, and a driving pulley is provided on the output shaft of the speed regulating motor. A transmission belt is wound around the driving pulley and the two driven pulleys respectively.

[0010] In one possible implementation, two grinding steel brushes are symmetrically arranged on the same grinding shaft, and the driven pulley is located in the middle of the grinding shaft and between the two grinding steel brushes.

[0011] In one possible implementation, multiple positioning holes are provided on both sides of the upper end face of the rust removal frame. The multiple positioning holes are arranged at intervals along the axial direction perpendicular to the steel pipe to be rusted. The bearing seat is installed on the rust removal frame through any two positioning holes on the same side.

[0012] In one possible implementation, the bottom of the speed-regulating motor is provided with several adjusting shims.

[0013] In one possible implementation, the inner wall of the dustproof box is lined with sound-insulating cotton.

[0014] In one possible implementation, a partition is provided in the middle of the dust box, the partition being located between the grinding steel brush and the speed-regulating motor.

[0015] In one possible implementation, the partition is inclined, a cleaning port is provided on one side of the dust box, the cleaning port is equipped with an opening and closing door, and the cleaning port is located at the downwardly inclined end of the partition.

[0016] In one possible implementation, the top of the dust collection box is provided with multiple water mist nozzles.

[0017] The beneficial effects of this environmentally friendly online steel pipe surface rust removal device are as follows: Compared with the prior art, the steel pipe to be rusted is placed on two sets of power components. The output shaft of the roller conveyor motor drives the spherical roller conveyor to rotate. Since the output shafts of the two roller conveyor motors are coaxially arranged and at an angle to the transmission direction of the steel pipe, the steel pipe to be rusted can be rotated and transmitted axially. During transmission, the steel pipe overlaps between two grinding steel brushes. The output shaft of the speed-regulating motor drives the two grinding shafts, which in turn drive the two grinding steel brushes to rotate synchronously in opposite directions, thus removing rust and grinding the outer surface of the steel pipe. The rust dust removed by grinding is sealed in a dustproof box and is sucked into a dust collection box for centralized collection by a blower on the dust suction pipe. This environmentally friendly online steel pipe surface rust removal device can achieve continuous grinding and rust removal of steel pipes without manual operation, reducing labor costs and improving the rust removal efficiency of steel pipes.

[0025] Please see Figure 1 and Figure 2 This invention provides an environmentally friendly online rust removal device for the outer surface of steel pipes. The device comprises a transmission mechanism, a rust removal mechanism, and a dust removal mechanism.

[0026] The transmission mechanism includes two sets of power components arranged at intervals along the transmission direction of the steel pipe. Each power component includes two roller motors 19, whose output shafts are coaxial and angled with the transmission direction of the steel pipe. The drive shafts of the roller motors 19 are connected to spherical roller conveyors 3. The two sets of spherical roller conveyors 3 rotate under the drive of their respective roller motors 19, driving the steel pipe 7 to be derusted to rotate and be transmitted axially. The derusting mechanism includes a derusting frame 8 positioned between the two power components. Two grinding shafts 5 are symmetrically arranged on the upper surface of the derusting frame 8. Grinding steel brushes 6 are mounted on the grinding shafts 5. The two grinding steel brushes 6 are... The rust removal frame 8 is arranged on both sides of the steel pipe conveying direction. A speed-regulating motor 1 is installed below the rust removal frame 8. The output shaft of the speed-regulating motor 1 is connected to two grinding shafts 5. The two grinding steel brushes 6 are driven to rotate synchronously in opposite directions to grind the outer surface of the steel pipe 7 to be rusted. The dust removal mechanism includes a dustproof box 9 and a dust collection box 12. The dustproof box 9 is covered outside the rust removal frame 8. The dust collection box 12 is set on one side of the dustproof box 9. A dust collection pipe 11 is connected between the dust collection box 12 and the dustproof box 9. A blower 10 is installed on the dust collection pipe 11. The blower 10 forms an airflow from the dustproof box 9 to the dust collection box 12 in the dust collection pipe 11.

[0027] This utility model provides an environmentally friendly online steel pipe rust removal device. Compared with the prior art, the steel pipe 7 to be rusted is placed on two sets of power components. The output shaft of the roller motor 19 drives the spherical roller 3 to rotate. Since the output shafts of the two roller motors 19 are coaxially arranged and at an angle to the transmission direction of the steel pipe, the steel pipe 7 to be rusted can be rotated and transmitted axially. During the transmission process, the steel pipe 7 overlaps between two grinding steel brushes 6. The output shaft of the speed regulating motor 1 drives the two grinding shafts 5, which in turn drive the two grinding steel brushes 6 to rotate synchronously in opposite directions, thus removing rust and grinding the outer surface of the steel pipe 7. The rust dust removed by grinding is sealed in the dustproof box 9 and is drawn into the dust collection box 12 by the blower 10 on the dust suction pipe 11. This utility model provides an environmentally friendly online steel pipe outer surface rust removal device, which can realize continuous grinding and rust removal of steel pipes without manual operation, reducing labor costs and improving the rust removal efficiency of steel pipes.

[0028] The roller conveyor motor 19 is mounted on the fixed base 18. When the roller conveyor motor 19 is mounted on the fixed base 18, the two are tightly connected together through a series of connecting components, such as bolts and nuts. This tight connection effectively limits the displacement and swaying of the roller conveyor motor 19 during operation.

[0029] Bearing seats 4 are respectively provided on the left and right sides of the upper end face of the rust removal frame 8. The two ends of the grinding shaft 5 are rotatably connected to the bearing seats 4 on the same side. A driven pulley 17 is provided on the grinding shaft 5, and a driving pulley is provided on the output shaft of the speed regulating motor 1. A transmission belt 2 is wound around the driving pulley and the two driven pulleys 17. As one of the core components in the rust removal operation, the grinding shaft 5 is rotatably connected to the bearing seats 4 on the same side at both ends. This connection method allows the grinding shaft 5 to rotate freely under the support of the bearing seats 4, providing the necessary power transmission basis for subsequent grinding and rust removal work. The grinding shaft 5 is usually made of high-quality alloy steel and undergoes a special heat treatment process, possessing good strength and toughness. It can withstand the large pressure and impact generated during the grinding process, while ensuring that it is not easily deformed, thereby ensuring the accuracy and stability of the grinding operation. The driven pulleys 17 are tightly connected to the grinding shaft 5. Through key connection or interference fit, it is ensured that the driven pulleys 17 can rotate synchronously and stably when the grinding shaft 5 rotates, realizing efficient power transmission. A drive pulley is mounted on the output shaft of the speed-regulating motor 1. The drive pulley is connected to the output shaft of the speed-regulating motor 1 via a key, ensuring that the drive pulley rotates precisely and synchronously with the output shaft when the speed-regulating motor 1 is running, stably transmitting the power of the speed-regulating motor 1 to the grinding shaft 5. The transmission belt 2 is made of high-performance rubber material with a high-strength fiber reinforcement layer inside, possessing good flexibility, wear resistance, and tensile strength. The transmission belt 2 forms a reliable power transmission link between the drive pulley and the driven pulleys 17. When the speed-regulating motor 1 starts, the drive pulley begins to rotate, and driven by the transmission belt 2, the two driven pulleys 17 also rotate synchronously, thereby driving the grinding shaft 5 to rotate at high speed, providing the necessary grinding power for rust removal operations.

[0030] Specifically, two grinding steel brushes 6 are symmetrically arranged on the same grinding shaft 5, and the driven pulley 17 is located in the middle of the grinding shaft 5 and between the two grinding steel brushes 6. The grinding steel brushes 6 are usually made of high-strength steel wire, which undergoes special heat treatment and surface treatment processes, giving them good toughness and wear resistance. Driven by the high-speed rotating grinding shaft 5, the grinding steel brushes 6 can quickly remove rust and oxide layers from the surface of the workpiece, and even stubborn rust can be cleaned with their powerful grinding ability.

[0031] Two grinding steel brushes 6 are symmetrically distributed on the grinding shaft 5, enabling a uniform and balanced grinding force during rust removal. When the grinding shaft 5 rotates at high speed, the grinding steel brushes 6 on both sides can simultaneously remove rust from the workpiece surface, avoiding uneven workpiece surface grinding caused by uneven force. Placing the driven pulley 17 in the middle position ensures that power is more evenly distributed to the grinding steel brushes 6 on both sides during transmission. When the drive belt 2 drives the driven pulley 17 to rotate, since the driven pulley 17 is in the center position, it can drive the two ends of the grinding shaft 5 with the same torque, keeping the rotation speed of the two grinding steel brushes 6 consistent, further ensuring the uniformity and stability of the rust removal work.

[0032] The rust removal frame 8 has multiple positioning holes 16 on both sides of its upper surface. These holes are spaced apart along an axial direction perpendicular to the steel pipe 7 to be rusted. The bearing seat 4 is mounted on the rust removal frame 8 through any two positioning holes 16 on the same side. The multiple positioning holes 16 are spaced apart in a specific direction, allowing for flexible adjustment of the bearing seat 4's installation position according to the specific size and shape of the steel pipe 7. This, in turn, adjusts the spacing between the two grinding steel brushes 6 to meet the rust removal requirements of steel pipes with different outer diameters.

[0033] Several adjusting shims are provided at the bottom of the speed-regulating motor 1. During operation, the speed-regulating motor 1 requires a high degree of horizontality and stability in its installation. These adjusting shims at the bottom of the speed-regulating motor 1 can effectively adjust the installation height of the speed-regulating motor 1, thereby adjusting the tension of the transmission belt 2.

[0034] Preferably, the inner wall of the dustproof box 9 is lined with sound-insulating cotton 14 to prevent the spread of noise generated when the grinding steel brush 6 rubs against the steel pipe to remove rust. The sound-insulating cotton 14 has a fibrous structure and porous characteristics, which can effectively capture and dissipate sound energy. When the grinding steel brush 6 rubs violently against the steel pipe, generating high-frequency, harsh noise, the interwoven fibers inside the sound-insulating cotton 14 form countless tiny sound-absorbing channels. After sound waves propagate into these channels, they are reflected and refracted multiple times on the fiber surface, and the energy is gradually consumed and converted into heat energy, thus effectively preventing further noise diffusion.

[0035] In addition, a partition is installed in the middle of the dust box 9, located between the grinding steel brush 6 and the speed-regulating motor 1. The partition has through holes for the transmission belt 2 to pass through. The partition can catch rust falling from the grinding steel pipe, which not only helps maintain the internal structural order of the equipment, but more importantly, it greatly reduces the potential adverse effects of rust generated during the grinding process on the speed-regulating motor 1. As the power core of the equipment, the speed-regulating motor 1 has a precise internal structure and requires a high degree of environmental cleanliness. Once rust enters the speed-regulating motor 1, it may accumulate in critical parts of the motor, such as bearings and coils, leading to increased friction during motor operation and affecting the motor's rotational efficiency.

[0036] Preferably, the partition is inclined, and a cleaning port 15 is provided on one side of the dust box 9. The cleaning port 15 is equipped with an opening and closing door and is located at the downward-sloping end of the partition. The inclined partition allows rust to naturally accumulate at the downward-sloping end of the partition under the influence of gravity. This avoids large-area accumulation of rust on the partition and makes centralized cleaning easier. Compared to horizontally arranged partitions, inclined partitions greatly reduce the difficulty and workload of rust cleaning and improve equipment maintenance efficiency. The cleaning port 15 on one side of the dust box 9, equipped with an opening and closing door, provides controllability and convenience for cleaning. When rust needs to be cleaned, the operator only needs to open the opening and closing door, and the rust can be smoothly discharged from the cleaning port 15 under the influence of gravity, eliminating the need for cumbersome internal cleaning operations and saving a significant amount of time and labor costs.

[0037] In addition, multiple water mist nozzles 13 are installed on the top of the dust collection box 12. The water mist nozzles 13 spray downward water mist, which has strong adsorption properties and can quickly capture dust particles floating in the air. As the water mist continues to sink downward, the adsorbed dust also sinks down with it and eventually settles at the bottom of the dust collection box 12. Excess water seeps into the turbid water tank for collection, and the dust that has settled at the bottom of the dust collection box 12 is cleaned and disposed of regularly.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
