Description

Technical Field

[0001] The present application relates to the technical field of crystallized copper tube cleaning, and in particular to a copper tube cleaning device. Background Art

[0002] During the metallurgical process, crystallized copper tubes need to be cleaned regularly to ensure their heat transfer efficiency and service life. These copper tubes may accumulate impurities such as scale, oxides, and metal residues during use, which hinder the cooling effect. The scale accumulation on the inner wall of the crystallized copper tube will affect the circulation of the cooling medium, reduce the heat transfer efficiency, cause uneven crystallization process, and affect the quality of the casting. Accumulated impurities and corrosive substances will accelerate the wear and corrosion of the copper tube. Regular cleaning can extend the life of the copper tube. Regular cleaning can prevent blockage, reduce the risk of damage and cracks in the copper tube, and reduce the occurrence of production accidents. Therefore, cleaning crystallized copper tubes is an important link in metallurgical production.

[0003] In the related technologies, the cleaning methods for copper tubes usually include chemical cleaning, mechanical cleaning, ultrasonic cleaning, water jet cleaning, etc. These related technologies can effectively clean copper tubes to a certain extent. At the same time, for copper tubes, both the inner and outer walls of the copper tubes need to be cleaned. Cleaning the inner wall can effectively improve the quality of the copper tube crystallization, and cleaning the outer wall can effectively ensure the heat transfer efficiency of the copper tube and extend the service life of the copper tube.

[0004] However, with the continuous development of metallurgical technology, copper tubes have more and more forms. In order to improve the cooling effect of the crystallizer, the surface shape of the copper tube is usually improved during the production process. For example, the surface of the copper tube is made concave and convex. Although this non-planar structure improves the cooling effect of the crystallizer to a certain extent, it also makes the surface of the copper tube difficult to clean to a certain extent, thereby reducing the heat transfer efficiency and service life of the copper tube. Therefore, a copper tube cleaning device is urgently needed to solve the above problems. Summary of the invention

[0042] The following is combined with Figures 1 to 5 This application is described in further detail.

[0043] The embodiment of the present application discloses a copper tube cleaning device.

[0044] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0045] Reference Figure 1A copper tube cleaning device includes a chassis 2, an inner wall cleaning mechanism 4, an outer wall cleaning mechanism 5 and a transmission mechanism 6. When the copper tube 1 is to be cleaned, especially when the copper tube 1 with a concave-convex outer surface is to be cleaned, the copper tube 1 is first positioned on the chassis 2. After positioning, the inner wall cleaning mechanism 4 is started. The inner wall cleaning mechanism 4 can clean the inner wall of the copper tube 1. Under the action of the transmission mechanism 6, the outer wall cleaning mechanism 5 will simultaneously clean the outer wall. The synchronous cleaning of the inner and outer walls of the copper tube 1 effectively reduces the influence of impurities attached to the copper tube 1 on the effect of the copper tube 1. The present application has the ability to effectively clean the inner and outer walls of the copper tube 1 at the same time to a certain extent, thereby improving the cooling effect and service life of the copper tube 1.

[0046] Specifically, in the embodiment of the present application, the chassis 2 is arranged in an open rectangular parallelepiped shape. In other embodiments, the chassis 2 can also be arranged in an open cube or cylinder shape, which is also an embodiment that the present application can implement.

[0047] Furthermore, a sewage drawer 12 is also provided on the chassis 2 , and the sewage drawer 12 is movably connected to the chassis 2 .

[0048] It should be noted here that the reason why the sewage drawer 12 is set is that during the cleaning process of the copper tube 1, especially the cleaning process of the inner and outer walls, a large amount of sewage will be generated, including chemical cleaning liquid residues and impurities flushed down, such as scale, oxides, metal chips and other sediments. These pollutants should be discharged and cleaned in time.

[0049] The drain drawer 12 provides a convenient way to drain sewage, which can collect sewage and impurities generated during the cleaning process, facilitate regular cleaning and maintenance, reduce pollution to the environment, and improve the cleanliness of the equipment. When the chassis 2 needs to be cleaned, the staff can extract the drain drawer 12 for cleaning.

[0050] Furthermore, a positioning assembly 3 is provided on the chassis 2, and the positioning assembly 3 can position the copper tube 1. Specifically, the positioning assembly 3 includes a first positioning bracket 31 and a second positioning bracket 32. The first positioning bracket 31 is arranged on the side of the edge of the chassis 2 close to the inner wall cleaning mechanism 4, and the second positioning bracket 32 ​​is arranged on the edge of the chassis 2 away from the end of the second positioning bracket 32. In the embodiment of the present application, the first positioning bracket 31 and the second positioning bracket 32 ​​can be understood as two brackets for hanging the copper tube 1. This is because the copper tube 1 itself has a certain weight, so it only needs to be able to keep the copper tube 1 stable. The first positioning bracket 31 abuts the upper edge of the inner wall of the copper tube 1, and the second positioning bracket abuts the upper edge of the inner wall on the other side of the copper tube 1. In order to prevent the copper tube 1 from rotating during the cleaning process, the first positioning bracket 31 and the second positioning bracket 32 ​​are both arranged in a forked shape.

[0051] The positioning component 3 ensures the stable positioning of the copper tube 1 and avoids displacement or rotation of the copper tube 1 during cleaning. At the same time, the forked setting can minimize contact with the inner wall of the copper tube 1 while ensuring that the copper tube 1 does not twist, thereby ensuring the cleaning quality of the inner wall of the copper tube 1 to a certain extent.

[0052] Furthermore, an adjusting rod 33 is provided on the second positioning bracket 32 ​​, and the adjusting rod 33 can adjust the length of the second positioning bracket 32 ​​.

[0053] The adjusting rod 33 provides flexibility and can be adjusted according to the length of the copper tube 1 to accommodate copper tubes 1 of different specifications.

[0054] In combination with the above content, a detailed explanation is given on how the positioning component 3 positions the copper tube 1: when the copper tube 1 is to be cleaned, the copper tube 1 needs to be positioned first, and the staff moves one end of the copper tube 1 laterally to the first positioning bracket 31, so that the first positioning bracket 31 abuts against the upper edge of the inner wall of the copper tube 1, and then the staff adjusts the adjusting rod 33, allowing the second screw to drive the second positioning bracket 32 ​​to move laterally, and the second positioning bracket 32 ​​extends into the copper tube 1 and abuts against the upper edge of the inner wall of the copper tube 1, thereby realizing the positioning of the copper tube 1 and facilitating the cleaning of the copper tube 1.

[0055] Specifically, refer to Figure 2 , Figure 3 and Figure 4 In the embodiment of the present application, the inner wall cleaning mechanism 4 is arranged on one side edge of the chassis 2, and the inner wall cleaning mechanism 4 can clean the inner wall of the copper tube 1. The inner wall cleaning mechanism 4 includes a cleaning motor 41 and a cleaning roller 42. The cleaning roller 42 is coaxially arranged with the rotating shaft of the cleaning motor 41, and the cleaning roller 42 can extend into the copper tube 1. It should be noted here that when positioning the copper tube 1, it is necessary to pay attention to adjusting the position of the copper tube 1, and the cleaning roller 42 does not directly abut against the inner wall of the copper tube 1. At the same time, a detergent can be applied to the cleaning roller 42 to enhance the cleaning effect, which is relatively easy to understand for those skilled in the art, so it will not be described in detail in the embodiment of the present application.

[0056] The cleaning motor 41 drives the cleaning roller 42 to rotate, thereby achieving efficient cleaning of the inner wall of the copper tube 1. The cleaning roller 42 penetrates deeply into the inner wall of the copper tube 1, and can remove impurities deposited on the inner wall to ensure the cleanliness of the inner wall.

[0057] Specifically, the outer wall cleaning mechanism 5 is arranged on the edge of one side adjacent to the chassis 2 and the inner wall cleaning mechanism 4. The outer wall cleaning mechanism 5 can clean the outer wall of the copper tube 1. The outer wall cleaning mechanism 5 includes an outer wall cleaning component 51 and a cleaning frame 52. The outer wall cleaning component 51 is fixedly connected to one end of the cleaning frame 52. The cleaning component can drive the cleaning frame 52 to reciprocate. The cleaning frame 52 is provided with a flanging brush, which contacts the outer wall of the copper tube 1. It should be noted that the flanging brush is not specifically shown in the drawings of the present application specification, which is relatively easy to understand for those skilled in the art and should not be used as a limitation to the present invention.

[0058] It should be noted that, for the copper tube 1 with a concave-convex outer wall in the embodiment of the present application, the flange brush used is a relatively hard brush, which can better clean the stains in the gap of the outer wall.

[0059] The outer wall cleaning component 51 cleans the outer wall of the copper tube 1 through reciprocating motion. The flange brush is in close contact with the outer wall and can effectively remove the deposits on the outer wall. The reciprocating motion helps to clean the stripes or uneven surfaces more thoroughly and improve the cleaning effect.

[0060] Furthermore, the outer wall cleaning assembly 51 includes a rotating gear 511 and a reciprocating frame 512. The rotating gear 511 is an incomplete gear 10. The reciprocating frame 512 is fixedly connected to a first rack 8 and a second rack 9. The rotating gear 511 can mesh with the first rack 8 and the second rack 9 in sequence. The cleaning frame 52 is fixedly connected to the reciprocating frame 512.

[0061] The incomplete gear 10 cooperates with the rack to realize the reciprocating motion of the cleaning frame 52, so that the outer wall can be cleaned repeatedly. The reciprocating motion can cover a larger surface area and the cleaning effect is more thorough.

[0062] Furthermore, the reciprocating frame 512 is provided with an extension rod 11, and a plurality of cleaning frames 52 are provided, and the plurality of cleaning frames 52 are provided in parallel with each other. In the embodiment of the present application, for the convenience of display, a total of three cleaning frames 52 are provided. In other embodiments, the cleaning frames 52 are provided in four, five or other numbers, which are all preferred embodiments of the present application.

[0063] The parallel arrangement of the plurality of cleaning frames 52 allows a larger area to be covered in one cleaning action, thereby improving the cleaning efficiency.

[0064] Specifically, refer to Figure 5 The transmission mechanism 6 is arranged between the inner wall cleaning mechanism 4 and the outer wall cleaning mechanism 5 so that the inner wall cleaning mechanism 4 drives the outer wall cleaning mechanism 5 to work.

[0065] The transmission mechanism 6 includes a first transmission wheel group 61, a second transmission wheel group 62 and a conversion component 63. The conversion component 63 is arranged between the first transmission wheel group 61 and the second transmission wheel group 62. The first transmission wheel group 61 includes a first driving wheel 611 and a first passive wheel 612. The first driving wheel 611 is coaxially arranged with the cleaning motor 41, and the cleaning motor 41 can drive the first driving wheel 611 to rotate. A synchronous belt is arranged between the first passive wheel 612 and the first driving wheel 611. The second transmission wheel group 62 includes a second transmission wheel 621 and a second passive wheel 622. The conversion component 63 can drive the second transmission wheel 621 to rotate. A synchronous belt is arranged between the second transmission wheel 621 and the second passive wheel 622. The second passive wheel 622 is coaxially arranged with the rotating gear 511.

[0066] The design of the transmission mechanism 6 enables the inner and outer wall cleaning mechanisms 5 to work in coordination under the action of the synchronous belt drive, and the design of the first and second transmission wheel sets 62 and the conversion assembly 63 ensures the accuracy and efficiency of the transmission.

[0067] Furthermore, the conversion assembly 63 includes a first bevel gear 631 and a second bevel gear 632 . The first bevel gear 631 is coaxially arranged with the first driven wheel 612 , and the second bevel gear 632 is coaxially arranged with the second transmission wheel 621 . The first bevel gear 631 and the second bevel gear 632 are meshed.

[0068] The design of the bevel gear allows power to be transmitted smoothly between different shafts, effectively enabling the outer wall cleaning mechanism 5 to clean the copper tube 1 synchronously with the inner wall cleaning mechanism 4, thereby ensuring the stability and efficiency of the entire transmission system. Compared with the prior art of separately cleaning the inner and outer walls of the copper tube 1, the copper tube 1 cleaning device of the present application is more efficient.

[0069] In combination with the above, a specific explanation is given here on how the transmission mechanism 6 works: when the copper tube 1 is positioned, the staff starts the cleaning motor 41, and the rotating shaft of the cleaning motor 41 rotates, driving the first driving wheel 611 to rotate, and the first driving wheel 611 drives the first driven wheel 612 to rotate through the synchronous belt, and the rotation of the first driven wheel 612 drives the first bevel gear 631 to rotate, and the first bevel gear 631 is meshed with the second bevel gear 632, so the second bevel gear 632 rotates, and the second bevel gear 632 drives the second transmission wheel 621 to rotate, and under the action of the synchronous belt, the second driven wheel 622 also rotates, and the rotation of the second driven wheel 622 will drive the rotation of the rotating gear 511, because the rotating gear 511 is an incomplete gear 10, it will mesh with the first rack 8 and the second rack 9 in turn, that is, the reciprocating motion of the reciprocating frame 512 is realized, thereby effectively realizing the transmission of the inner wall cleaning mechanism 4 to the outer wall cleaning mechanism 5.

[0070] The implementation principle of a copper tube cleaning device in an embodiment of the present application is as follows: the copper tube 1 cleaning device of the present application is configured as a combination of a chassis 2, an inner wall cleaning mechanism 4, an outer wall cleaning mechanism 5 and a transmission mechanism 6, so that when the copper tube 1 is to be cleaned, it is only necessary to position the copper tube 1 on the chassis 2, and then start the inner wall cleaning mechanism 4. Under the action of the transmission mechanism 6, the outer wall of the copper tube 1 can be cleaned simultaneously while the inner wall is being cleaned, thereby effectively adapting to the copper tube 1 with a concave-convex outer surface in the related art, and being able to effectively clean the copper tube 1 with a concave-convex outer surface. The present application has the ability to effectively clean the inner and outer walls of the copper tube 1 at the same time to a certain extent, thereby improving the cooling effect and service life of the copper tube 1.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
