Description

Technical Field

[0001] This utility model belongs to the field of cast and rolled plate production technology, and in particular relates to a device for treating soot on the surface of cast and rolled plates. Background Technology

[0002] In the casting and rolling process, molten aluminum is rolled by rolls to form cast and rolled plates. To prevent sticking to the rolls, graphite spraying lubrication or flame lubrication is required. During flame lubrication, some large pieces of incompletely burned soot will stick to the rolls. During the rolling process, the soot will be carried into the surface of the cast and rolled plate. The soot on the surface will affect the quality of the cast and rolled billet. The soot pressed into the surface has a very serious impact on subsequent rolling.

[0003] Currently, cleaning soot mainly relies on manual labor. Generally, towels or rags are used to wipe away the excessive black substances accumulated on the edges, which easily contaminates the edges. The cleaning process poses safety hazards, as it involves high-temperature operations that can easily cause burns, and it is difficult to clean thoroughly, thus failing to effectively remove soot from the surface of the cast iron plate.

[0004] Of course, existing technologies involve devices for cleaning the surface of rolling mill rolls. These typically consist of a retractable cleaning head with a cleaning cloth or cotton attached. During roll operation, the cleaning head is driven close to the roll to perform the cleaning operation. However, during online cleaning, due to continuous roll lubrication, the cleaning cloth or cotton on the cleaning head accumulates and absorbs excessive black substances as cleaning time increases. Furthermore, the cleaning head cannot be replaced online, easily leading to secondary contamination and ineffective removal of soot from the surface of the cast-rolled plate. Utility Model Content

[0005] In view of the technical problems existing in the background art, the present invention provides a device for treating soot on the surface of cast and rolled plates.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A device for treating soot on the surface of a cast-rolled plate includes a cleaning mechanism located on one side of the roll. The cleaning mechanism includes a mounting block and a flipping block. The mounting block is U-shaped, with grooves on its inner walls on both sides, and a slider sliding in each groove. The flipping block is located inside the mounting block, and its upper and lower ends are rotatably connected to the sliders via shafts. A cleaning component is mounted on the flipping block, and a rocker arm is hinged to the end of the flipping block away from the shaft. One end of the rocker arm is hinged to the mounting block. A first cylinder is mounted on the mounting block, and a first piston rod is located inside the first cylinder. The end of the first piston rod is hinged to the flipping block. The first cylinder can retract and fold the flipping block inside the mounting block, and the first cylinder can extend and flip the flipping block outward, causing the cleaning component to be tightly attached to the surface of the roll.

[0008] Optionally, a second cylinder is provided on one side of the flipping block, the second cylinder is located on the back of the dust removal assembly, a second piston rod is provided inside the second cylinder, one end of the second piston rod is connected to the connecting block, and both sides of the connecting block are respectively connected to the U-shaped drive rod; an adjustment groove is provided inside the flipping block, the dust removal assembly is slidably arranged in the adjustment groove, and one end of the drive rod is connected to the dust removal assembly.

[0009] Optionally, the two sides of the flipping block are respectively provided with sliding holes communicating with the adjustment groove, and the drive rod is partially slidably disposed in the sliding hole. The drive rod extends into the adjustment groove through the sliding hole and connects with the dust removal assembly.

[0010] Optionally, a limiting block is provided at the end of the mounting block. When the first cylinder retracts and the flipping block is folded and stored inside the mounting block, and the mounting block and the flipping block are parallel, one side of the flipping block is set close to the limiting block.

[0011] Optionally, the dust removal assembly includes an adjusting block, a mounting base, and a cleaning cotton. The adjusting block is slidably disposed in the adjusting groove, and a drive rod is connected to the adjusting block. The mounting base is detachably disposed on the adjusting block, and the cleaning cotton is disposed on the mounting base.

[0012] Optionally, the upper and lower sides of the flipping block are respectively provided with side grooves, and a number of hinge holes are evenly distributed on the side grooves. A hinge shaft is provided inside one end of the sliding groove. One end of the swing rod is connected to the hinge shaft, and the other end is hinged to one of the hinge holes by a pin.

[0013] Optionally, an intermediate shaft is provided at the middle of one end of the flipping block, and the end of the first piston rod is hinged to the intermediate shaft.

[0014] Optionally, a sliding sleeve is provided on one side of the flipping block, and one side of the drive rod is slidably disposed on the inner wall of the sliding sleeve. The sliding sleeve and the second cylinder are disposed on the same side of the flipping block.

[0015] Optionally, the limiting block is provided with a receiving groove in the middle. When the first cylinder retracts and the flipping block is folded and stored inside the mounting block, the second cylinder and the sliding sleeve are disposed in the receiving groove.

[0016] Optionally, the mounting block is provided with several connecting holes on both sides, the roll is mounted on the roll seat, and the mounting block is mounted on the side wall of the roll seat through the connecting holes.

[0017] This utility model has the following advantages and beneficial effects:

[0018] This invention addresses the problem of large pieces of soot adhering to the sides of the rolls during lubrication due to incomplete combustion during flame lubrication. An adjustable cleaning mechanism is designed to address this issue. By adjusting the relative positions of the flipping block and the mounting block, a first cylinder retracts, linking the flipping block to fold and store it inside the mounting block. When cleaning is not required, the cleaning mechanism is retracted. The first cylinder extends, linking the flipping block to rotate outwards from the mounting block, ensuring the cleaning component is in close contact with the roll surface. When cleaning is needed, the flipping block rotates to clean the soot from both sides of the roll. After a period of cleaning, the flipping block can be moved away from the roll again, allowing for online replacement of the cleaning mechanism. This avoids secondary contamination caused by prolonged contact between the cleaning component and the roll, preventing ineffective removal of soot from the cast-rolled plate surface and thus improving cleaning efficiency.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1-10 As shown, a soot treatment device for the surface of a cast-rolled plate includes a cleaning mechanism 2 located on one side of a roller 11. Two rollers 11 are provided, mounted on a roller seat 1. A cast-rolled plate 12 lies between the rollers 11. The cleaning mechanism 2 is installed on the side of the cast-rolled plate 12 exiting the plate. Figure 1 As shown, there are four cleaning mechanisms 2, one of which is symmetrically arranged on both sides of each roller 11. This arrangement is because, during the flame lubrication process, some large pieces of incompletely burned soot will stick to the sides of the roller 11, while the middle part of the roller 11 is relatively smooth and clean. This is the area where the cast and rolled plate 12 passes through, so the cleaning is mainly carried out on the two sides of the roller 11.

[0039] like Figures 1 to 15 As shown, the dust removal mechanism 2 includes a mounting block 3 and a tilting block 4. The mounting block 3 is fixed on the roll seat 1 and is U-shaped. Slide grooves 31 are provided on the inner walls of both sides of the mounting block 3, and sliders 8 are slidably mounted in the slide grooves 31. The tilting block 4 is located inside the mounting block 3. The upper and lower ends of the tilting block 4 are rotatably connected to the sliders 8 via rotating shafts 46. The position of the tilting block 4 can be changed by sliding the sliders 8. A dust removal assembly is provided on the tilting block 4. A swing rod 9 is hinged to the end of the tilting block 4 away from the rotating shaft 46. One end of the swing rod 9 is hinged to the mounting block 3, and the hinge point is located at the end of the slide groove 31. A first cylinder 5 is provided on the mounting block 3, and a cylinder groove 36 is opened inside the mounting block 3. The first cylinder 5 is fixed in the cylinder groove 36 by screws. A first piston rod 51 is provided inside the first cylinder 5, and the first piston rod 51 extends into the interior of the mounting block 3. The end of the first piston rod 51 is hinged to the flipping block 4. Specifically, an intermediate shaft 45 is provided in the middle of the flipping block 4, and the end of the first piston rod 51 is hinged to the intermediate shaft 45. The intermediate shaft 45 and the rotating shaft 46 are both located on the same side of the flipping block 4. The first cylinder 5 can retract and link the flipping block 4 to fold and store it inside the mounting block 3. The first cylinder 5 can also extend and link the flipping block 4 to flip it outward from the mounting block 3, so that the dust removal assembly is closely attached to the surface of the roller 11.

[0040] The first cylinder 5 is the driving component, and the flipping block 4 is the driven component.

[0041] like Figure 9 and Figure 10 As shown, at this time, the flipping block 4 is stored inside the mounting block 3. At this time, the slider 8 approaches the first cylinder 5, the first cylinder 5 retracts, and pulls the flipping block 4 back into the mounting block 3. At this time, the swing rod 9 is parallel to the mounting block 3 and the flipping block 4, achieving compact storage.

[0042] like Figures 1 to 8As shown, when the first cylinder 5 gradually extends, the hinge of the slider 8 and the flipping block 4, as well as the action of the swing rod 9, drives the flipping block 4 to gradually flip, eventually causing the flipping block 4 to flip 90 degrees, so that the dust removal component on the flipping block 4 contacts the two side surfaces of the roller 11, thereby achieving dust removal.

[0043] In this invention, to address the problem that large pieces of soot tend to stick to the sides of the roll 11 during lubrication due to incomplete combustion during flame lubrication, an adjustable cleaning mechanism is designed. By adjusting the relative positions of the flipping block 4 and the mounting block 3, the first cylinder 5 retracts, linking the flipping block 4 to fold and store it inside the mounting block 3. When cleaning the roll 11 is not required, the cleaning mechanism is stored in place. The first cylinder 5 can extend, linking the flipping block 4 to flip it outwards from the mounting block 3, ensuring the cleaning component is in close contact with the surface of the roll 11. When cleaning is needed, the flipping block 4 contacts and cleans the soot from both sides of the roll 11. After a period of cleaning, the flipping block 4 can be moved away from the roll 11 again, allowing for online replacement of the cleaning mechanism. This avoids secondary contamination caused by prolonged contact between the cleaning component and the roll 11, preventing ineffective removal of soot from the surface of the cast-rolled plate 12, thus improving cleaning efficiency.

[0044] Example 2

[0045] To ensure that the dust removal mechanism 2 can use cast and rolled plates 12 of different widths, and to enable the dust removal assembly to be adjusted in position along the length of the roll 11, further optimization design was made.

[0046] like Figures 1 to 15 As shown, a second cylinder 7 is provided on one side of the flipping block 4, and the second cylinder 7 is located on the back of the dust removal assembly. A second piston rod 71 is located inside the second cylinder 7, with one end connected to a connecting block 72. Both sides of the connecting block 72 are connected to U-shaped drive rods 73. An adjustment groove 41 is provided inside the flipping block 4, and the dust removal assembly is slidably disposed in the adjustment groove 41. One end of the drive rod 73 is connected to the dust removal assembly. By extending and retracting the second cylinder 7, the dust removal assembly is controlled to move within the adjustment groove 41, achieving lateral adjustment. This allows the dust removal assembly to clean dust along different positions of the rolls 11, adapting to cast-rolled plates 12 of different widths.

[0047] like Figure 9 and Figure 10 As shown, at this time, the flipping block 4 is stored inside the mounting block 3. At this time, the second cylinder 7 also needs to retract to ensure that the second piston rod 71 can be stored inside the mounting block 3, achieving compact storage.

[0048] like Figures 1 to 8As shown, when the first cylinder 5 gradually extends, the hinge between the slider 8 and the tilting block 4, along with the action of the swing arm 9, drives the tilting block 4 to gradually tilt, eventually causing it to tilt 90 degrees. This allows the cleaning component on the tilting block 4 to contact the two side surfaces of the roller 11, thus achieving cleaning. After the tilting block 4 has tilted to a certain angle, the extension and retraction of the second cylinder 7 can be controlled to control the position of the cleaning component relative to the roller 11, adjusting the cleaning position.

[0049] Furthermore, sliding holes 47 communicating with the adjustment groove 41 are respectively provided on both sides of the flip block 4. The sliding holes 47 are provided on both sides of the intermediate shaft 45, so that the drive rod 73 is staggered from the intermediate shaft 45 and the first piston rod 51. The drive rod 73 is partially slidably disposed in the sliding hole 47. After the drive rod 73 is bent, it extends into the adjustment groove 41 through the sliding hole 47 and connects with the dust removal assembly.

[0050] Furthermore, a limiting block 33 is provided at the end of the mounting block 3. When the first cylinder 5 retracts and the flipping block 4 is folded and stored inside the mounting block 3, and the mounting block 3 and the flipping block 4 are parallel, one side of the flipping block 4 is set tightly against the limiting block 33. The limiting block 33 is used to limit the flipping block 4 after it is stored. At the same time, when the first cylinder 5 extends, it ensures that the flipping block 4 can only flip away from the limiting block 33, thereby getting closer to the roller 11 to achieve dust removal.

[0051] In this invention, the dust removal assembly includes an adjusting block 62, a mounting base 61, and a cleaning cotton 6. The adjusting block 62 is slidably disposed in the adjusting groove 41, and the side of the adjusting groove 41 away from the intermediate shaft 45 passes through the side wall of the flipping block 4 (e.g., Figure 13 As shown), this ensures that the adjusting block 62 can be installed easily and quickly. The drive rod 73 is connected to the adjusting block 62. A mounting base 61 is detachably mounted on the adjusting block 62, and a cleaning cotton 6 is mounted on the mounting base 61. One side of the adjusting groove 41 has a notch 42, and the mounting base 61 extends to the outside of the notch 42. The cleaning cotton 6 is mounted on the mounting base 61. Figure 3 As shown, the mounting base 61 and the cleaning cotton 6 have sufficient thickness to ensure a safe gap between the flipping block 4 and the roller 11, while also ensuring that the flipping block 4 always maintains a distance from the roller 11 during the flipping process, and only the cleaning cotton 6 can contact the roller 11.

[0052] Furthermore, the upper and lower sides of the flipping block 4 are respectively provided with side grooves 43, and several hinge holes 44 are evenly distributed on the side grooves 43. A hinge shaft 32 is provided inside one end of the sliding groove 31. One end of the swing rod 9 is connected to the hinge shaft 32, and the other end is hinged to one of the hinge holes 44 by a pin. With this design, the swing rod 9 is always located in the side groove 43 during the swinging process.

[0053] Furthermore, a sliding sleeve 48 is provided on one side of the flipping block 4, and one side of the drive rod 73 is slidably disposed in the positioning hole 49 of the sliding sleeve 48 to achieve sliding limit of the drive rod 73. The sliding sleeve 48 and the second cylinder 7 are disposed on the same side of the flipping block 4. The positions of the connecting block 72 and the intermediate shaft 45 are staggered, so that the two will never collide or interfere with each other during the flipping process of the flipping block 4.

[0054] Furthermore, a receiving groove 34 is provided in the middle of the limiting block 33. When the first cylinder 5 retracts, it links with the flipping block 4 to fold and store inside the mounting block 3. The second cylinder 7 and the sliding sleeve 48 are partially disposed in the receiving groove 34 (e.g., Figure 9 (As shown).

[0055] Furthermore, several connecting holes 35 are provided on both sides of the mounting block 3, the roll 11 is mounted on the roll seat 1, and the mounting block 3 is mounted on the side wall of the roll seat 1 through the connecting holes 35.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
