Description

Technical Field

[0001] The present invention relates to the technical field of mooring chain single-loop processing, in particular to a single-loop heat treatment method and equipment for an R5-grade mooring chain. Background Art

[0002] R5-grade mooring chain is a high-grade mooring chain type in the current marine engineering equipment field. It is specially designed for complex deep-sea working conditions. R5-grade mooring chain uses high-purity steel smelted by micro-alloying technology and has the advantages of high tensile strength and strong fatigue resistance.

[0003] After the R5-level mooring chain is put into use, some single links of the mooring chain will be damaged due to long-term external force. Therefore, the single links of the mooring chain need to be repaired. During the repair process, the defective part needs to be cut first, and then layered welding is performed after cutting. After welding, it is heated using a mesh belt heating furnace.

[0004] When repairing a single ring of a mooring chain, the metal and debris generated during the cutting process will adhere to the surface of the single ring in large quantities under the action of cooling water spraying to suppress dust or rinsing with cutting groove cleaning water. After completing the welding process, the single ring is sent to a mesh belt heating furnace for heat treatment. In a high temperature environment, these attached debris will undergo physical and chemical changes and fuse with each other to form block-like debris. As the treatment process progresses, the block-like debris will loosen due to heat and fall onto the mesh belt. Since the mesh belt is continuously in a high temperature state and the block-like debris has a certain viscosity at high temperature, it will adhere to the surface of the mesh belt. When a new single ring enters the furnace for heat treatment, the block-like debris already adhered to the mesh belt will be transferred and attached to the surface of the single ring again, which will not only affect the surface quality of the single ring, but may also interfere with the temperature conduction and uniformity during the heat treatment process, and ultimately have an adverse effect on the heat treatment effect and product performance of the single ring. Summary of the Invention

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention starts a driving motor during the heat treatment process, and the driving motor drives the cleaning rod to rotate, and the rotation of the cleaning rod drives the cleaning brush to rotate. When the mesh-belt conveyor belt is working, the cleaning brush can clean up the debris attached to the mesh-belt conveyor belt body. The cleaned debris enters the installation shell, enters the discharge pipe through the installation shell, enters the guide pipe, and finally enters the collection box, thereby cleaning the debris attached to the mesh-belt conveyor belt body. It can reduce the adhesion of debris to the mooring chain single ring when the mesh-belt conveyor belt body is placed again after circulating to the feeding end, reduce the impact on the quality of the mooring chain single ring after heat treatment, thereby improving the repair quality of the mooring chain single ring, and at the same time cleaning the mesh-belt conveyor belt body, thereby reducing the impact of debris on the normal operation of the mesh-belt conveyor belt;

[0027] 2. When the cleaning rod is driven by the driving motor to rotate and clean the mesh belt conveyor belt, the cleaning rod rotates, causing the driving gear to rotate, and the driving gear rotates to drive the driven gear, thereby causing the rotating rod to rotate, and the rotating rod rotates to drive the rotating block to rotate. As the rotating block rotates, the vibrating block will contact the mesh belt conveyor belt and vibrate the belt. When the belt is vibrated, the debris stuck in the gap of the belt will be vibrated, thereby avoiding the jamming phenomenon caused by debris when the belt rotates to the end bend, thereby improving the running smoothness of the mesh belt conveyor belt and making it smoother. It is beneficial to heat-treat the single ring of the mooring chain. At the same time, when debris falls on the belt body, it is affected by high temperature. The high temperature greatly increases the atomic activity of the surface of some metal block debris, so that it has a certain adsorption force and is adsorbed on the belt body. However, cleaning with a cleaning brush may not be thorough. At this time, by vibrating the belt body, the belt body is subjected to force, so that the debris adsorbed on the surface falls off, and then the debris is removed by rotating the cleaning brush, thereby improving the cleaning effect of the cleaning brush, reducing the impact of debris on the single ring when the belt body circulates to the feeding position, and improving the heat treatment effect of the single ring;

[0028] 3. When the cleaning rod is driven by the driving motor to rotate to clean the mesh belt conveyor belt, the cleaning rod rotates, causing the pulley 1 to rotate accordingly, and under the action of the transmission belt, the pulley 2 rotates, thereby causing the transmission rod to rotate, and the rotation of the transmission rod causes the impeller to rotate. The rotation of the impeller generates suction inside the collection box, thereby collecting the dust particles generated during the cleaning process, reducing the impact of the dust particles generated during the cleaning process on the surrounding environment, and reducing the dust from being scattered and falling on the unheat-treated mooring chain single ring. At the same time, the dust particles generated during the cleaning process are collected, which can prevent the dust from falling on the conveyor belt again, thereby improving the cleaning effect of the cleaning brush, further reducing the impact of debris on the single ring of the mesh belt conveyor belt when it circulates to the feeding point, and improving the heat treatment effect of the single ring.

The support frame is provided with a rapping component 3, and the rapping component 3 is used to rap the belt body of the mesh belt conveyor belt 11, so that the debris is better separated from the mesh belt conveyor belt 11, which is more convenient for the subsequent cleaning brush 24 to clean. The lower end of the impurity removal component 2 is provided with a collecting component 4, and the collecting component 4 can be used to clean the dust generated during the cleaning process to reduce the scattering of dust;

[0049] The impurity removal component 2 includes an installation shell 21 installed at the discharge end of the mesh belt conveyor 11. The installation shell 21 is fixedly connected to the support leg at the lower end of the support frame 1, and the installation shell 21 is supported and installed by the support leg. A cleaning rod 23 is rotatably connected inside the installation shell 21, and a cleaning brush 24 is fixed on the cleaning rod 23. The cleaning brush 24 is a ceramic composite fiber brush. The brush of ceramic composite material has good high temperature resistance, that is, it will not be deformed due to high temperature when it contacts the heated mesh belt conveyor 11. A driving motor 22 is fixed on the side of the installation shell 21. By driving The motor 22 drives the cleaning rod 23 to rotate, and the rotation of the cleaning rod 23 drives the cleaning brush 24 to rotate. When the mesh-belt conveyor belt 11 is working, the cleaning brush 24 can sweep away the debris attached to the belt body of the mesh-belt conveyor belt 11, which can reduce the adhesion of debris to the mooring chain single ring when the mooring chain single ring is placed again. The drive motor 22 is electrically connected to the controller 14, and the output end of the drive motor 22 is fixedly connected to the cleaning rod 23. A recovery member 25 is provided at the lower end of the mounting housing 21. The recovery member 25 is used to recover the debris that falls off the mesh-belt conveyor belt 11, which is convenient for subsequent centralized processing;

[0050] The cleaning rod 23 is driven to rotate by the driving motor 22, so that the cleaning brush 24 rotates. At the same time, the driving motor 22 drives the rapping assembly 3 to work and rap the belt body of the mesh belt conveyor belt 11.

[0052] A barrier net 254 is fixed inside the discharge pipe 251. The barrier net 254 can block large pieces of debris to prevent them from falling into the collection box 41 and affecting dust collection. The barrier net 254 is tilted and tilted toward the guide pipe 252. The barrier net 254 tilted toward the guide pipe 252 can allow debris to quickly enter the interior of the guide pipe 252.

[0053] During use, when heat-treating a single mooring chain ring, the welded and repaired single mooring chain ring is placed on the feeding end of the mesh belt conveyor 11, and the mesh belt conveyor is started to convey the single mooring chain ring to the bottom of the heating furnace 12. Then, the mesh belt conveyor is stopped, and the single mooring chain ring is heated by the heating furnace 12. After heating for a period of time and reaching a specified temperature, the mesh belt conveyor 11 is started to convey the heated single mooring chain ring into the insulation furnace 13, and insulation treatment is carried out by the insulation furnace 13. After insulation treatment for a period of time, the mesh belt conveyor 11 is started to convey the single mooring chain ring out of the insulation furnace 13 and to the discharging end.

[0055] Example 2

[0056] See also Figure 3 、 Figure 5 、 Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that:

[0057] The rapping assembly 3 includes a rotating rod 31 rotatably connected to the side of the supporting frame 1, and the rotating rod 31 extends into the interior of the mesh belt conveyor 11, so that the rapping member 34 can rap the belt body of the mesh belt conveyor 11. One end of the rotating rod 31 is fixed with a driven gear 32. When the cleaning rod 23 rotates, it drives the driving gear 33 to rotate, and the driving gear 33 rotates to drive the driven gear 32, so that the rotating rod 31 rotates, and the rotating rod 31 rotates to drive the rapping member 34 to rotate. A driving gear 33 meshing with the driven gear 32 is fixed on the cleaning rod 23. The diameter of the driving gear 33 is smaller than the diameter of the driven gear 32, so that the speed of the driven gear 32 is less than the speed of the driving gear 33, thereby reducing the speed of the rotating rod 31, so that the rapping member 34 is at a suitable rapping frequency, avoiding the material from being vibrated off due to excessive rapping frequency. A rapping member 34 is provided on the rotating rod 31.

[0058] The rapping member 34 includes a rotating block 341 fixed on the rotating rod 31. There are multiple rotating blocks 341. Multiple rapping blocks 342 can improve the rapping effect and are more conducive to separating debris from the belt body of the mesh belt conveyor 11. A rapping block 342 is installed on the side of the rotating block 341. The rapping block 342 is a high-temperature resistant fluororubber block. The rapping block 342 made of high-temperature resistant rubber material can avoid wear caused by the rapping block 342 rapping the belt body of the mesh belt conveyor 11.

[0059] A movable groove 343 is provided inside the rotating block 341, and a plurality of conflicting springs 345 are fixed inside the movable groove 343. A movable block 344 is fixed to the side of the rapping block 342 near the rotating block 341. The movable block 344 slides into the movable groove 343 and is fixedly connected to the conflicting springs 345. When the rapping block 342 contacts the belt body of the mesh-belt conveyor belt 11, the rapping block 342 is subjected to force to squeeze the movable block 344, so that the movable block 344 moves inside the movable groove 343, squeezing the conflicting springs 345 during movement. When the rapping block 342 is no longer in contact with the mesh-belt conveyor belt 11, the rapping block 342 is reset under the action of the conflicting springs 345. By providing the rapping block 342 with a certain range of motion, it is possible to avoid damage to the belt body of the mesh-belt conveyor belt 11 caused by hard rapping.

[0060] The cleaning rod 23 of the embodiment of the present invention is a kind of cleaning rod 23 of the invention, which is a kind of cleaning rod 23 of the invention, and the cleaning rod 23 of the invention is a kind of cleaning rod 23 of the invention, which is a kind of cleaning rod 23 of the invention, and the cleaning rod 23 of the invention is a kind of cleaning rod 23 of the invention, and the cleaning rod 23 of the invention is a kind of cleaning rod 23 of the invention, and the cleaning rod 23 of the invention is a kind of cleaning rod 23 of the invention, and the cleaning rod 23 of the invention is a kind of cleaning rod The smoothness of the operation of the belt conveyor 11 is more conducive to the heat treatment of the single ring of the mooring chain. At the same time, when debris falls on the belt body, it is affected by high temperature. The high temperature greatly increases the surface atomic activity of some metal block debris, so that it has a certain adsorption force and is adsorbed on the belt body. However, there is a phenomenon of incomplete cleaning by the cleaning brush 24. At this time, the belt body is vibrated to make the belt body bear force, so that the debris adsorbed on its surface falls off, and then the cleaning brush 24 is rotated to remove the debris, thereby improving the cleaning effect of the cleaning brush, reducing the impact of the single ring caused by debris when the belt body circulates to the loading point, and improving the heat treatment effect of the single ring.

[0061] The remaining structures are the same as those of Example 1.

[0062] Example 3

[0063] See also Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0064] The collecting assembly 4 includes a collecting box 41 fixed at the lower end of the discharge pipe 251. A through hole is opened at the bottom of the collecting box 41, and the through hole is used for discharging air when the impeller 43 rotates. A transmission rod 42 is connected to the inside of the collecting box 41, and an impeller 43 is fixed on one end of the transmission rod 42 extending into the inside of the collecting box 41. A transmission part 44 is provided between the transmission rod 42 and the cleaning rod 23. The transmission part 44 is driven by the rotation of the cleaning rod 23, so that the transmission rod 42 rotates, and the transmission rod 42 rotates and drives the impeller 43 to rotate, so that suction is generated inside the collecting box 41, and the dust generated during the cleaning process of the cleaning brush 24 is sucked into the inside of the collecting box 41, thereby reducing the dust from floating around.

[0065] The transmission member 44 includes a pulley 1 441 fixed on the cleaning rod 23, and a pulley 2 442 is fixed on the transmission rod 42. The pulley 1 441 and the pulley 2 442 are connected by a transmission belt 443. When the driving motor 22 drives the cleaning rod 23 to rotate, the pulley 1 441 rotates accordingly. Under the action of the transmission belt 443, the pulley 2 442 rotates, thereby causing the transmission rod 42 to rotate, providing power for the rotation of the impeller 43, and playing a transmission role.

[0066] The collecting box 41 is provided with a mounting groove on the side, and a mounting frame 45 is slidingly provided inside the mounting groove. The bottom of the mounting frame 45 is hollow and a collecting net 451 is fixed thereto. The impeller 43 generates suction inside the collecting box 41, and the dust generated during the cleaning process of the cleaning brush 24 is sucked into the collecting box 41 and falls onto the collecting net 451, which collects the dust. The end of the mounting frame 45 extending out of the mounting groove is fixed with a mounting plate 452, and the mounting plate 452 is detachably connected to the collecting box 41. A handle is fixed on the mounting plate 452. When the collecting net 451 needs to be cleaned, the mounting plate 452 is separated from the collecting box 41, the handle is pulled, the mounting frame 45 is taken out, and then the collecting net 451 is cleaned. After cleaning, it is inserted into the mounting groove again, and the mounting plate 452 is connected to the collecting box 41, thereby realizing the cleaning of the collecting net 451. The cleaning process is more convenient and more conducive to collecting the dust generated during the cleaning process.

[0067] The rotation of the transmission belt 443 causes the pulley 442 to rotate, thereby causing the transmission rod 42 to rotate. The rotation of the transmission rod 42 causes the impeller 43 to rotate, and the rotation of the impeller 43 causes suction to be generated inside the collecting box 41, thereby collecting the dust particles generated during the cleaning process, which can reduce the impact of the dust particles generated during the cleaning process on the surrounding environment, reduce the dust from floating around and falling on the unheated mooring chain single ring, and at the same time collect the dust particles generated during the cleaning process, which can prevent the dust from falling on the conveyor belt again, thereby improving the cleaning effect of the cleaning brush 24, further reducing the impact of the mesh belt conveyor belt 11 on the single ring caused by debris when the belt body circulates to the loading point, and improving the heat treatment effect of the single ring. As the dust particles generated during the cleaning process are collected, when more dust particles are attached to the collection net 451, the suction force inside the collection box 41 will be reduced. At this time, the collection net 451 needs to be cleaned. When cleaning, the mounting plate 452 is separated from the collection box 41, and the handle is pulled to take out the mounting frame 45. Then, the collection net 451 is cleaned and inserted into the mounting slot after cleaning. The mounting plate 452 is connected to the collection box 41 to achieve the cleaning of the collection net 451. The cleaning process is more convenient, more conducive to the collection of dust generated during the cleaning process, and improves convenience.

[0068] The remaining structures are the same as those of Examples 1 and 2.
