Description

Technical Field

[0001] The present application belongs to the technical field of steel pipe rust removal mechanical equipment, and in particular to a steel pipe rust removal device. Background Art

[0002] Steel pipes are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes according to their materials. They are divided into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. according to their uses.

[0003] Nowadays, when welding brackets, many round steel pipes are used. Steel pipes are prone to rust when placed outdoors for a long time. Generally, when welding brackets, the steel pipes are first cut and then welded. After the rusty steel pipes are cut, they must be polished when welding to remove the rust on the surface. One is for beauty, and the other is to make the welding more firm. When the steel pipes are welded, the rust will also be welded in and become part of the welding point, but because the rust is relatively loose, it will cause the welding to be loose and cause the welding to break; at the same time, the steel pipes are buried in the soil to transport natural gas, liquefied gas and other substances. It will be obviously found that steel pipes without rust removal will accelerate the corrosion rate of steel pipes. Rust removal machines are now used for rust removal. Steel sand is blown onto the steel pipe to clean the rust on the surface of the steel pipe. At the same time, sand marks are made on the surface so that when the steel pipe is subsequently painted, the paint can better adhere to the surface of the steel pipe. However, the existing equipment uses steel sand to spray in one direction, that is, spraying steel sand from top to bottom for rust removal, and the rust removal efficiency is low. At the same time, in the process of rust removal, due to the low rust removal efficiency, the steel pipe needs to be rusted for many times. At this time, if the steel pipe is damaged, the steel sand will collide with the damaged area for many times, accelerating the damage of the steel pipe. Summary of the invention

[0004] In view of this, it is necessary to provide a steel pipe rust removal device with high efficiency.

[0005] The solution of this application to solve the technical problem is:

[0009] Preferably, the rebound member is a cylindrical rod.

[0010] Preferably, there are multiple columnar bars, and the multiple columnar bars are evenly arranged on the inner wall of the rust remover.

At the same time, due to the increase of the sandblasting heads, the number of sprayed steel sand is increased, and the collision density between the steel sand and the steel pipe is increased, so that the rust removal purpose of the steel pipe can be completed in one time, and the rust removal efficiency is improved; at the same time, a rebound component is arranged, and the rebound component is arranged at the The inner wall of the rust remover is provided with a protrusion, and the rebound member forms a protrusion, which is used to rebound the steel sand splashed randomly during the rust removal process.

[0021] In the figure: a rust remover 10, a first set of sandblasting heads 20, a second set of sandblasting heads 30, a rebound assembly 40, a rebound member 401, a U-shaped mounting rod 4011, a rotating drum 4012, a second protrusion 4013, a clamping portion 4014, a mounting plate 402, and a clamping interface 4021. DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0023] Please see Figures 1 to 3 , a steel pipe rust removal device, comprising a rust removal machine 10 and a first group of sandblasting heads 20 and a second group of sandblasting heads 30 symmetrically arranged in the rust removal machine 10, wherein the first group of sandblasting heads 20 are arranged at the top of the rust removal machine 10, and the second group of sandblasting heads 30 are arranged at the bottom of the rust removal machine 10, for sandblasting the surface of the steel pipe from multiple angles; and

[0024] The rebound component 40 includes a rebound member 401, which is arranged on the inner wall of the rust remover 10 and forms a protrusion. The rebound member 401 rebounds part of the steel sand to the surface of the steel pipe for secondary rust removal.

[0025] The first group of sandblasting heads 20 and the second group of sandblasting heads 30 provided in the steel pipe rust removal device are used to remove rust from multiple angles during the rust removal process. At the same time, due to the increase in the number of sandblasting heads, the number of steel sands sprayed is increased, the collision density between the steel sands and the steel pipe is increased, and the efficiency of rust removal is improved. When the first group of sandblasting heads 20 and the second group of sandblasting heads 30 are specifically provided, the first group of sandblasting heads 20 and the second group of sandblasting heads 30 can be respectively provided at the top and the bottom of the rust removal machine 10. At this time, the first group of sandblasting heads 20 spray downward. Steel sand, the second group of sandblasting heads 30 spray steel sand upward; or the two sandblasting heads in the first group of sandblasting heads 20 are symmetrical and tilted at the two ends of the top of the rust remover 10, and similarly, the two sandblasting heads in the second group of sandblasting heads 30 are symmetrical and tilted at the two ends of the bottom of the rust remover 10. At this time, the four sandblasting heads spray steel sand from four directions to collide with the surface of the steel pipe, thereby improving the rust removal efficiency. Due to the improvement of the rust removal efficiency, the number of repeated rust removal is reduced, and the multiple collisions between the steel sand and the damaged parts of the steel pipe are reduced, thereby avoiding accelerated damage to the steel pipe.

[0026] At the same time, the rebound component 40 rebounds the steel sand splashed during the rust removal process. At this time, the steel sand will collide with the protrusion formed on the rebound component 401. At this time, a part of the steel sand after rebounding will collide with the steel pipe again. The steel sand after rebounding also has strong kinetic energy, which further removes rust from the steel pipe; at the same time, the rebound component 401 is arranged on the inner wall of the rust remover 10, which avoids the collision of the steel sand with the inner wall of the rust remover 10, which is equivalent to forming a protective layer on the inner wall of the rust remover 10, avoiding the situation where the inner wall of the rust remover 10 is smashed into pits, thereby improving the service life of the rust remover 10, and due to the improvement of the rust removal purpose, the number of repeated rust removal is reduced, and multiple collisions between the steel sand and the damaged position of the steel pipe are avoided.

[0027] In a specific implementation, the rebound member 401 is a first protrusion.

[0028] When setting the first protrusion, a round protrusion or a square protrusion can be selected to achieve the purpose of rebounding steel sand. At the same time, when setting the first protrusion, a regular setting or an irregular setting can be selected. When manufacturing the structure, welding or one-piece molding can be selected, which is simple to manufacture.

[0029] Furthermore, the rebound member 401 is a cylindrical rod.

[0030] The rebound member 401 can be set as a columnar bar, such as a cylindrical steel bar or a square steel bar, which can be welded to the inner wall of the rust remover 10 when in use. The material is easy to obtain, and the formed protrusions can be used to achieve the purpose of rebounding steel sand for secondary rust removal.

[0031] In a specific use scenario, the cylindrical bars can be arranged in a chaotic state on the inner wall of the rust remover 10. However, such an arrangement is likely to cause irregular rebound of the steel sand. Based on this, in an alternative embodiment, the number of the cylindrical bars is multiple, and the multiple cylindrical bars are arranged in a uniform state on the inner wall of the rust remover 10.

[0032] When arranging the cylindrical bars, the cylindrical bars can be arranged side by side on the inner wall of the rust remover 10 to make the steel sand rebound regularly and improve the rebound efficiency of the protrusions on the steel sand during the rust removal process.

[0033] In a specific embodiment, the rebounding assembly 40 further includes a mounting plate 402. The rebounding member 401 includes a U-shaped mounting rod 4011 and a rotating cylinder 4012. One end of the U-shaped mounting rod 4011 is hinged to the mounting plate 402. A clamping portion 4014 is provided at the other end of the U-shaped mounting rod 4011. The clamping portion 4014 is clamped with the mounting plate 402, and the other end of the U-shaped mounting rod 4011 can be removed from the mounting plate 402. The rotating cylinder 4012 is sleeved on the U-shaped mounting rod 4011, and the rotating cylinder 4012 forms a protrusion.

[0034] The rebounding assembly 40 further includes the mounting plate 402. During use, the rebounding member 401 is arranged on the mounting plate 402. The mounting plate 402 is used to fix the rebounding member 401. At the same time, if the rebounding member 401 is used for too long, under the impact of the steel sand, the surface of the rebounding member 401 will become pitted. At this time, it is necessary to replace the rebounding member 401. When replacing the rebounding member 401, according to the specific setting situation, when replacing the rebounding member 401, the whole rebounding assembly 40 can be replaced, or the rebounding member 401 can be replaced. At the same time, a bearing can be provided between the U-shaped mounting rod 4011 and the rotating cylinder 4012. When the rotating cylinder 4012 contacts the steel sand, the rotating cylinder 4012 can rotate on the U-shaped mounting rod 4011 to make the rotating cylinder 4012 evenly stressed and avoid the situation that one side of the rotating cylinder 4012 contacts the steel sand repeatedly, resulting in one side of the rotating cylinder 4012 being damaged and the other side being intact.

[0035] In a specific embodiment, a clamping interface 4021 is formed on the mounting plate 402, and the clamping interface 4021 is clamped with the clamping portion 4014.

[0036] To facilitate the firm clamping of the clamping portion 4014 onto the clamping plate and also facilitate the removal of the clamping portion 4014 from the clamping plate, a clamping opening 4021 is formed on the mounting plate 402, and the clamping portion 4014 can be clamped in the clamping opening 4021. When specifically arranged, the clamping portion 4014 can be a spherical ball, and the clamping opening 4021 is a groove, and this spherical ball can be clamped in this groove. When the rotating cylinder 4012 needs to be replaced, the spherical ball can be pulled out from the groove. On the one hand, the U-shaped mounting rod 4011 is fixed on the mounting plate 402, and on the other hand, it is more convenient to remove the U-shaped mounting rod 4011 from the mounting plate 402.

[0037] Further, a second convex block 4013 is provided on the rotating cylinder 4012.

[0038] The steel sand after the first rust removal collides with the rotating cylinder 4012 in a disorderly state. A second convex block 4013 is provided on the rotating cylinder 4012 (the second convex block 4013 can be arranged orderly or disorderly, and the rotating cylinder 4012 with the second convex block 4013 can be formed in one piece or the second convex block 4013 can be welded to the rotating cylinder 4012). The steel sand will first collide with the second convex block 4013. After being used for a period of time, the second convex block 4013 is flattened, and then the steel sand will collide with the rotating cylinder 4012, thereby prolonging the service life of the rotating cylinder 4012.

[0039] In a preferred embodiment, the rebound assembly 40 is provided on each inner sidewall of the rust remover 10.

[0040] To improve the rebound efficiency of the steel sand during rust removal and avoid the impact of the steel sand on the inner sidewall of the rust remover 10, the rebound assembly 40 is provided on each inner sidewall of the rust remover 10 to protect the inner sidewall of the rust remover 10.

[0041] In a specific embodiment, a plurality of the rebound members 401 are provided on each inner sidewall of the rust remover 10.

[0042] To improve the rebound efficiency of the steel sand during rust removal and avoid the impact of the steel sand on the inner sidewall of the rust remover 10, a plurality of the rebound members 401 are provided on each inner sidewall of the rust remover 10, so that the rebound members 401 form a protective layer on the entire inner sidewall of the rust remover 10, thereby protecting the inner sidewall of the rust remover 10.

[0043] In a specific usage scenario, any two adjacent rotating cylinders 4012 are in contact with each other.

[0044] When steel sand is splashed during the rebound rust removal process, if there is a gap between the rotating drum 4012, the steel sand will enter between the mounting plate 402 and the rebound member 401 along the gap. On the one hand, the steel sand is stuck between the mounting plate 402 and the rebound member 401 and cannot be reused. On the other hand, since the steel sand is stuck between the mounting plate 402 and the rebound member 401, if too much steel sand is stuck, the rotating drum 4012 will be unable to rotate, causing the rotating drum 4012 to repeatedly contact with the splashing steel sand.

[0045] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
