Description

Technical Field

[0001] This invention relates to the field of pipeline rust removal equipment technology, and in particular to a rust removal equipment for pipelines used in the production of high-pigment carbon black. Background Technology

[0002] In the carbon black production process, pyrolysis is one of the key steps. During this process, in addition to generating the required carbon black, gaseous products may also be generated. As the production process proceeds, water vapor will condense and adhere to the inner wall of the pipe, resulting in excessive humidity on the inner wall of the pipe, which will accelerate the corrosion process of the inner wall of the pipe. This corrosion will not only affect the service life of the pipe, but may also cause product quality problems due to the shedding of rust particles generated by the corrosion. Therefore, a pipe rust removal device is needed to remove rust from the inner wall of the pipe.

[0003] The announcement number CN117798792B describes a rust removal device for high-pigment carbon black production pipelines. It addresses the technical drawback of existing rust removal devices for carbon black production pipelines, which cannot pre-clean the carbon black residue on the inner wall of the pipeline, resulting in poor rust removal effect. However, in actual use, similar structures still have many defects. For example, existing pipeline rust removal devices can only achieve linear movement or rotation in one direction. This single movement not only limits the rust removal contact area but may also lead to incomplete rust removal in some areas due to ineffective contact.

[0004] Therefore, the aforementioned technical problems need to be solved. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention proposes a rust removal device for high pigment carbon black production pipelines, which solves the problem that the single motion form not only limits the rust removal contact area, but also causes some areas to be incompletely rusted because they are not effectively touched.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0007] A rust removal device for a high-pigment carbon black production pipeline includes a rotating shroud, a rust removal mechanism, and a reciprocating drive mechanism. It also includes two positioning mechanisms rotatably mounted at both ends of the rotating shroud. An adjustment mechanism is rotatably mounted inside the rotating shroud, and the output end of the adjustment mechanism is connected to the two positioning mechanisms via a transmission connection. A fixed gear is rotatably mounted at one end of the rotating shroud.

[0008] The reciprocating drive mechanism is rotatably installed inside the rotating cover. The reciprocating drive mechanism consists of a servo motor, a gear set, a threaded rod, a transmission spline rod, a planetary gear, and a transmission assembly. The servo motor is fixedly installed at one end of the rotating cover. The output end of the servo motor is connected to the threaded rod and the transmission spline rod respectively through the gear set. A planetary gear is fixedly installed at one end of the threaded rod. The transmission assembly is sleeved on the outside of the threaded rod and the transmission spline rod.

[0009] The rust removal mechanism is movably mounted on the top of the rotating cover via a slide rail groove, and the bottom end of the rust removal mechanism is mounted on the top of the transmission assembly via a turntable;

[0010] The servo motor drives the threaded rod and the transmission spline rod to rotate simultaneously through the gear set. The rotating threaded rod drives the transmission component to move linearly, and the linearly moving transmission component drives the rust removal mechanism to move linearly. At the same time, the rotating threaded rod rotates around the fixed gear planet through the planetary gear. The planetary gear drives the rust removal mechanism to rotate through the rotating cover. Meanwhile, the rotating transmission spline rod drives the rust removal mechanism to rotate on its own axis through the transmission component. This allows the rust removal mechanism to rotate around the fixed gear while moving linearly, and the rust removal mechanism to rotate on its own axis, thus achieving the grinding and rust removal of the inside of the pipe.

[0011] Preferably, the transmission assembly comprises a thread sleeve seat, a first bevel gear, a second bevel gear, a third bevel gear, and a cleaning plate. The first bevel gear is rotatably mounted inside the thread sleeve seat, wherein the first bevel gear has a spline hole inside, and the second bevel gear has a through hole inside. The first bevel gear is sleeved on the outside of the transmission spline rod through the spline hole, and the second bevel gear is threaded on the outside of the threaded rod through the threaded hole, and the first bevel gear and the second bevel gear are meshed together. The third bevel gear is rotatably mounted on the top of the thread sleeve seat, and the cleaning plate is fixedly mounted on the bottom of the thread sleeve seat.

[0012] Preferably, the third bevel gear has a spline hole inside, and the third bevel gear is meshed with the second bevel gear.

[0013] Preferably, the rust removal mechanism consists of a grinding disc, a telescopic spline rod, a mounting spline sleeve, a spring element, and a spline connecting rod. The telescopic spline rod is fixedly installed at the bottom of the grinding disc by locking bolts. The mounting spline sleeve is sleeved on the outside of the telescopic spline rod. The spring element is fixedly installed at the bottom end of the telescopic spline rod. The spline connecting rod is fixedly installed at the bottom end of the mounting spline sleeve. The third bevel gear is sleeved on the outside of the spline connecting rod.

[0014] Preferably, the movable cover is fixedly sleeved on the outside of the spline sleeve, and the movable cover is movably mounted on the top of the rotating cover.

[0015] Preferably, the positioning mechanism consists of a mounting frame, a telescopic frame, rollers, a drive motor, a traction block, and a curved groove disc. Four telescopic frames are movably mounted in a circular array inside the mounting frame. Rollers are rotatably mounted inside one end of each of the four telescopic frames. A drive motor is fixedly mounted on one side of one end of each of the four telescopic frames, and the output end of the drive motor is fixedly connected to the rollers. The curved groove disc is rotatably mounted on one side of the mounting frame, and an adjusting curved groove is formed in a circular array inside the curved groove disc. A traction block is fixedly mounted on one end of each telescopic frame, and the traction block extends into the adjusting curved groove inside the curved groove disc.

[0016] Preferably, the adjustment mechanism consists of a dual-axis motor, a first shaft, and a second shaft. The dual-axis motor is fixedly installed at one end of the rotating cover, and the first shaft and the second shaft are respectively fixedly installed at the two output ends of the dual-axis motor. The first shaft passes through the interior of the positioning mechanism, and one end of the first shaft and the second shaft are respectively connected to the two positioning mechanisms for transmission.

[0017] Preferably, the top of the rotating cover is provided with a slide rail groove, a protective cover is fixedly installed inside the rotating cover, a protective cover is fixedly installed at one end of the rotating cover, and the protective cover covers the outside of the servo motor and the dual-axis motor.

[0018] The beneficial effects of this invention are:

[0019] The technical solution of this invention uses a servo motor to drive a gear set, which in turn rotates a threaded rod and a transmission spline rod. The rotating threaded rod drives a transmission assembly meshing with it to move linearly, thereby driving the rust removal mechanism to advance along the axial direction of the pipe, ensuring full coverage. Simultaneously, the rotating threaded rod rotates around a fixed gear meshing with it via a planetary gear. During this process, the rotating planetary gear drives a rotating cover to rotate around the axis of the fixed gear, thereby driving the rust removal mechanism to rotate and expanding the rust removal coverage area. This allows the rust removal mechanism to form a spiral advancing trajectory within the pipe, covering the entire inner wall area. At the same time, the rotating transmission spline rod further drives the rust removal mechanism to rotate via the transmission assembly, generating radial grinding force.

[0020] Thus, the rust removal mechanism forms a three-dimensional composite motion mode of "rotation + linear movement + self-rotation"; the three motions superimpose to form a spiral propulsion trajectory, achieving rust removal without dead angles; the three-dimensional composite motion mode simultaneously generates radial grinding force and axial scraping force, effectively peeling off rust layers of different depths; and the three-dimensional composite motion mode breaks through the limitations of traditional unidirectional rust removal, ensuring uniform rust removal, and is suitable for comprehensive rust removal operations on pipes of different distances and diameters.

[0034] The following will be combined with the appendix Figure 1 To be continued Figure 11The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] A rust removal device for a high-pigment carbon black production pipeline includes a rotating cover 1, a rust removal mechanism 3, and a reciprocating drive mechanism 4. It also includes two positioning mechanisms 2 rotatably installed at both ends of the rotating cover 1. An adjustment mechanism 5 is rotatably installed inside the rotating cover 1. The output end of the adjustment mechanism 5 is connected to the two positioning mechanisms 2 in a transmission manner. A fixed gear 104 is rotatably installed at one end of the rotating cover 1.

[0036] One end of the fixed gear 104 is fixedly connected to one side of one of the positioning mechanisms 2, so that the rotating cover 1 rotates relative to the positioning mechanism 2; the rust removal mechanism 3 is driven by the reciprocating drive mechanism 4, so as to achieve rotation and linear movement at the same time, thereby cleaning the inner wall of the pipe efficiently; the reciprocating drive mechanism 4 provides additional power through a reciprocating motion, so that the rust removal mechanism 3 moves back and forth inside the pipe, enhancing the rust removal effect; the positioning mechanism 2 is fixedly installed inside the pipe, and the positioning mechanism 2 can drive the rotating cover 1 to move inside the pipe to adjust the rust removal position; the adjusting mechanism 5 is used to adjust the expansion range of the positioning mechanism 2 to adapt to pipes of different diameters;

[0037] The reciprocating drive mechanism 4 is rotatably installed inside the rotating cover 1. The reciprocating drive mechanism 4 consists of a servo motor 401, a gear set 402, a threaded rod 403, a transmission spline rod 404, a planetary gear 405, and a transmission assembly 406. The servo motor 401 is fixedly installed at one end of the rotating cover 1. The output end of the servo motor 401 is connected to the threaded rod 403 and the transmission spline rod 404 respectively through the gear set 402. The planetary gear 405 is fixedly installed at one end of the threaded rod 403. The transmission assembly 406 is sleeved on the outside of the threaded rod 403 and the transmission spline rod 404.

[0038] The servo motor 401 provides the power source and is fixedly installed at one end of the rotating cover 1. It is connected to the threaded rod 403 and the transmission spline rod 404 through the gear set 402, so that the threaded rod 403 and the transmission spline rod 404 run synchronously. The gear set 402 acts as a transmission device, transmitting the rotational motion of the servo motor 401 to the threaded rod 403 and the transmission spline rod 404 respectively, driving the threaded rod 403 and the transmission spline rod 404 to rotate. The rotating threaded rod 403 meshes with the transmission assembly 406 through the planetary gear 405 fixedly installed at one end, converting the rotational motion into planetary rotational motion. The rotating threaded rod 403 drives the transmission assembly 406 to move linearly along the threaded rod 403. The rotating transmission spline rod 404 drives the transmission assembly 406 to transmit to the rust removal mechanism 3, so that the rust removal mechanism 3 rotates.

[0039] The rust removal mechanism 3 is movably mounted on the top of the rotating cover 1 via the slide rail groove 101, and the bottom end of the rust removal mechanism 3 is mounted on the top of the transmission assembly 406 via a turntable;

[0040] The servo motor 401 drives the threaded rod 403 and the transmission spline rod 404 to rotate simultaneously through the gear set 402. The rotating threaded rod 403 drives the transmission component 406 to move linearly. The linearly moving transmission component 406 drives the rust removal mechanism 3 to move linearly. At the same time, the rotating threaded rod 403 rotates around the fixed gear 104 via the planetary gear 405. The planetary gear 405 drives the rust removal mechanism 3 to rotate via the rotating cover 1. Meanwhile, the rotating transmission spline rod 404 drives the rust removal mechanism 3 to rotate via the transmission component 406. This allows the rust removal mechanism 3 to rotate around the fixed gear 104 while moving linearly, and to rotate on its own axis, thus achieving the grinding and rust removal of the inside of the pipe by the rust removal mechanism 3.

[0041] It should be noted that the planetary gear 405 meshes with the fixed gear 104, and the servo motor 401, as a power source, transmits power through the gear set 402, simultaneously driving the threaded rod 403 and the transmission spline rod 404 to rotate. The rotating threaded rod 403 drives the transmission component 406 meshing with it to move linearly through its thread, thereby driving the rust removal mechanism 3 to move along a linear path. At the same time, the rotating threaded rod 403 rotates around the meshing fixed gear 104 through the planetary gear 405 fixedly connected to it. During this process, the rotating planetary gear 405 drives the rotating cover 1 to rotate around the axis of the fixed gear 104, thereby driving the rust removal mechanism 3 to rotate. Meanwhile, the rotating transmission spline rod 404 further drives the rust removal mechanism 3 to rotate on its own axis through the transmission component 406. Thus, the rust removal mechanism 3 achieves a working mode of simultaneous rotation and movement along a linear path, and also rotates on its own axis, realizing efficient rust removal operation for grinding the inner wall of the pipe.

[0042] like Figures 8 to 9 As shown, the transmission assembly 406 consists of a thread sleeve seat 4061, a first bevel gear 4062, a second bevel gear 4063, a third bevel gear 4064, and a cleaning plate 4065. The first bevel gear 4062 is rotatably mounted inside the thread sleeve seat 4061, wherein a spline hole is opened inside the first bevel gear 4062, and a through hole is opened inside the second bevel gear 4063. The first bevel gear 4062 is sleeved on the outside of the transmission spline rod 404 through the spline hole, and the second bevel gear 4063 is threaded on the outside of the threaded rod 403 through the threaded hole, and the first bevel gear 4062 and the second bevel gear 4063 are meshed together. The third bevel gear 4064 is rotatably mounted on the top of the thread sleeve seat 4061, and the cleaning plate 4065 is fixedly mounted on the bottom of the thread sleeve seat 4061.

[0043] It should be noted that the second bevel gear 4063 is rotatably mounted on one side of the thread sleeve seat 4061, and a thread sleeve is embedded inside the thread sleeve seat 4061. The thread sleeve and the second bevel gear 4063 are on the same axis. The threaded rod 403 passes through the thread sleeve inside the thread sleeve seat 4061 and the second bevel gear 4063. The third bevel gear 4064 is splinedly connected to the spline connecting rod 305 through the internal spline hole. The cleaning plate 4065 is fixed to the bottom of the thread sleeve seat 4061 and is used to remove rust-removing substances that enter the rotating cover 1 during operation.

[0044] The rotating transmission spline rod 404 drives the first bevel gear 4062 to rotate through the spline hole. The rotating first bevel gear 4062 drives the meshing second bevel gear 4063 to rotate. The rotating second bevel gear 4063 drives the spline-connected rust removal mechanism 3 to rotate. The high-speed rotation of the rust removal mechanism 3 generates grinding force to remove the rust layer on the inner wall of the pipe.

[0045] The rotating threaded rod 403 drives the threaded sleeve seat 4061 to move along the direction of the threaded rod 403 through the threaded sleeve. The displaced threaded sleeve seat 4061 drives the top rust removal mechanism 3 to move axially. At the same time, the rotating threaded rod 403 drives the planetary gear 405 to rotate around the meshing fixed gear 104. The planetary gear 405 drives the rust removal mechanism 3 to rotate through the rotating cover 1, so that the rust removal mechanism 3 forms a spiral propulsion trajectory in the pipeline, covering the entire area of ​​the inner wall of the pipeline.

[0046] like Figure 10 As shown, the third bevel gear 4064 has a spline hole inside, and the third bevel gear 4064 is meshed with the second bevel gear 4063.

[0047] It should be noted that the third bevel gear 4064 is sleeved on the outside of the spline connecting rod 305 through the spline hole. The rotating second bevel gear 4063 drives the meshing third bevel gear 4064 to rotate, and the rotating third bevel gear 4064 drives the spline connecting rod 305 to rotate.

[0048] like Figures 10 to 11 As shown, the rust removal mechanism 3 consists of a grinding disc 301, a telescopic spline rod 302, a mounting spline sleeve 303, a spring 304, and a spline connecting rod 305. The telescopic spline rod 302 is fixedly installed at the bottom of the grinding disc 301 by locking bolts. The mounting spline sleeve 303 is sleeved on the outside of the telescopic spline rod 302. The spring 304 is fixedly installed at the bottom end of the telescopic spline rod 302. The spline connecting rod 305 is fixedly installed at the bottom end of the mounting spline sleeve 303. The third bevel gear 4064 is sleeved on the outside of the spline connecting rod 305.

[0049] It should be noted that the bottom end of the spline connecting rod 305 is connected to the top of the threaded sleeve seat 4061 via a turntable. The telescopic spline rod 302 extends into the interior of the grinding disc 301, and the locking bolt is rotated to release the lock between the grinding disc 301 and the telescopic spline rod 302. The position of the grinding disc 301 on the outside of the telescopic spline rod 302 is adjusted, thereby adjusting the height of the grinding disc 301 for easy adjustment according to the pipe diameter. After the position of the grinding disc 301 is determined, the grinding disc 301 and the telescopic spline rod 302 are locked by rotating the locking bolt in the opposite direction. The spline sleeve 303 is installed as an intermediate connecting part to connect the telescopic spline rod 302 and the spline connecting rod 305 to transmit torque. The spring 304 provides elastic telescopic force, enabling the telescopic spline rod 302 to have telescopic force. When the grinding disc 301 encounters a protruding obstacle, the elastic telescopic force of the spring 304 allows the grinding disc 301 to pass through the obstacle.

[0050] The rotating third bevel gear 4064 drives the spline connecting rod 305 to rotate through the spline hole. The rotating spline connecting rod 305 drives the telescopic spline rod 302 to rotate through the spline sleeve 303. The rotating telescopic spline rod 302 drives the grinding disc 301 to rotate at high speed to generate grinding force and remove the rust layer on the inner wall of the pipe.

[0051] like Figure 2 , Figure 10 As shown, the movable cover 306 is fixedly sleeved on the outside of the mounting spline sleeve 303, and the movable cover 306 is movably mounted on the top of the rotating cover 1.

[0052] It should be noted that when the thread sleeve seat 4061 moves, it drives the movable cover 306 on the outside of the spline sleeve 303 to move as well. The movable cover 306 is used to block the rust layer removed by the grinding disc 301, reducing the amount of rust layer removed from entering the rotating cover 1.

[0053] like Figures 6 to 7 As shown, the positioning mechanism 2 consists of a mounting frame 201, a telescopic frame 202, rollers 203, a drive motor 204, a traction block 205, and a curved groove disk 206. Four telescopic frames 202 are movably mounted in a circular array inside the mounting frame 201. Rollers 203 are rotatably mounted inside one end of each of the four telescopic frames 202. A drive motor 204 is fixedly mounted on one side of one end of each of the four telescopic frames 202. The output end of the drive motor 204 is fixedly connected to the rollers 203. The curved groove disk 206 is rotatably mounted on one side of the mounting frame 201. An adjustable curved groove is opened in a circular array inside the curved groove disk 206. A traction block 205 is fixedly mounted on one end of the telescopic frame 202. The traction block 205 extends into the adjustable curved groove inside the curved groove disk 206.

[0054] It should be noted that the rotating curved groove plate 206, through the cooperation of the curved groove and the traction block 205, drives the telescopic frame 202 to move telescopically within the mounting frame 201, thereby adjusting the expansion range of the roller 203. This facilitates adjustment according to the pipe diameter, adapting to pipes of different diameters, and ensuring that the roller 203 fits against the inner wall of the pipe. The drive motor 204 drives the roller 203 to rotate, and the rotating roller 203 moves along the inner wall of the pipe, thereby driving the rotating cover 1 and its internal structure to move along the pipe, achieving smooth forward movement and facilitating the rust removal work inside the pipe.

[0055] like Figure 7 As shown, the adjustment mechanism 5 consists of a dual-axis motor 501, a first shaft 502, and a second shaft 503. The dual-axis motor 501 is fixedly installed at one end of the rotating cover 1. The first shaft 502 and the second shaft 503 are respectively fixedly installed at the two output ends of the dual-axis motor 501. The first shaft 502 passes through the interior of the positioning mechanism 2, and one end of the first shaft 502 and the second shaft 503 are respectively connected to the two positioning mechanisms 2 for transmission.

[0056] It should be noted that the first shaft 502 and the second shaft 503 serve as power transmission components. Driven by the dual-axis motor 501, power is transmitted from the two output ends of the dual-axis motor 501, respectively. The second shaft 503 penetrates the interior of the protective cover 103. The dual-axis motor 501 drives the first shaft 502 and the second shaft 503 to rotate synchronously. The synchronously rotating first shaft 502 and the second shaft 503 respectively drive the curved groove disk 206 in the two positioning mechanisms 2 to rotate.

[0057] like Figures 1 to 3 As shown, the top of the rotating cover 1 is provided with a slide rail groove 101, a protective cover 102 is fixedly installed inside the rotating cover 1, and a protective cover 103 is fixedly installed at one end of the rotating cover 1, and the protective cover 103 covers the outside of the servo motor 401 and the dual-axis motor 501.

[0058] It should be noted that the spline sleeve 303 extends into the slide rail groove 101, allowing the spline sleeve 303 to move within the slide rail groove 101; the protective cover 102 protects the first shaft 502 from the intrusion of external dust and impurities; the protective cover 103 covers the outside of the servo motor 401 and the dual-axis motor 501, protecting the servo motor 401 and the dual-axis motor 501 from damage caused by the external environment.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and alterations to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
