Description

Technical Field

[0001] This invention relates to the field of fine steel spraying technology, and in particular to a plasma spraying equipment and method for fine steel thin-film fireproof coating. Background Technology

[0002] To meet the fire protection requirements of refined steel structures, fire-retardant coatings need to be applied to the surface of the steel during the production process. Conventional fire-retardant coatings for steel structures rely on thick-coat application, using solvent-based intumescent coatings or cement-based materials. This results in problems such as heavy coatings, long application periods, and susceptibility to cracking and peeling, making it difficult to meet the demands of modern buildings for lightweight construction and high durability. By using plasma spraying equipment to apply a thin layer of fire-retardant coating to the surface of refined steel, the uniformity and adhesion of the fire-retardant coating are improved.

[0003] Conventional plasma spraying equipment uses a high-frequency plasma spray gun to atomize nano-level fire-retardant coatings for application. Uniform coating is achieved by adjusting the spray gun's movement in the X / Y directions and controlling the rotation of the steel frame relative to the gun. However, in conventional methods of coating square steel frames, to improve spraying accuracy, the steel frame needs to be clamped before spraying. This clamping makes it difficult to rotate the steel frame, hindering the uniform coverage of the steel frame. Therefore, this solution proposes a plasma spraying equipment and method for thin-film fire-retardant coatings on steel frames to address these issues. Summary of the Invention

[0031] This invention also proposes a method for plasma spraying a thin-film fire-retardant coating for refined steel, which is completed using the aforementioned plasma spraying equipment for thin-film fire-retardant coatings for refined steel, and includes the following steps:

[0032] S1. Place the fine steel drag on the machining seat;

[0033] S2. Adjust the clamping block to slide closer to the refined steel to complete the clamping process of the refined steel;

[0034] S3. Apply fire-retardant coating to refined steel using plasma spraying equipment;

[0038] The plasma spraying equipment and method for applying thin-film fire-retardant coatings to steel of the present invention have the following advantages over the prior art:

[0039] (1) The plasma spraying equipment of this application clamps the refined steel from one side with a clamping block by setting a side stop block. After the side stop block is disengaged from one side of the refined steel, the refined steel can be adjusted to flip. By setting the bottom wall of the side stop block as an inclined wall, the side stop block can rotate and move downward at the same time. This makes it convenient to adjust the rotation and downward movement of the side stop block by a cylinder. There is no need to set two driving parts to drive the rotation and sliding of the refined steel separately, which is convenient to use.

[0040] (2) By setting an adapter roller, specifically when it is necessary to adjust the pressure block to slide away from the refined steel, the adapter roller is adjusted to rotate. The adapter roller drives the assembly to rotate, and the sliding joint slides along the assembly, thereby completing the sliding adjustment of the pressure block. By setting the assembly and the pushing part to be set on opposite sides of the adapter roller, when the pressure block is adjusted to slide away from the refined steel to adjust the rotation of the refined steel, the pushing part moves synchronously closer to the refined steel and pushes the top side of the refined steel. The pushing part pushes the refined steel, which can assist the user in flipping the refined steel, making it convenient to use.

[0041] (3) By setting a drive belt, when performing surface spraying treatment of spherical or cylindrical refined steel, the second drive motor can be started simultaneously during spraying. At this time, the second drive motor drives the drive belt to rotate through the drive roller, and the drive belt drives the refined steel to rotate through friction, thereby completing the rapid flipping treatment of the refined steel. This allows the plasma spraying equipment to perform surface spraying treatment on the refined steel during the flipping process, improving spraying efficiency and making it convenient to use.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.

[0053] like Figures 1-8 As shown, the plasma spraying equipment for thin-film fire-retardant coating of refined steel of the present invention includes a processing base 1, a clamping block 2, a side stop block 31, a side connector 32, a connecting shaft 33, a transition shaft 34, a mounting plate 35, a cylinder 36, a support block 41, and a plasma spraying device 8. The processing base 1 supports the refined steel 10, and the clamping block 2 is slidably disposed on the processing base 1 to compress the refined steel 10. A first connecting groove 11 is provided on the top of the processing base 1, which connects to one side of the processing base 1 in the sliding direction of the clamping block 2. The side stop block 31 is located inside the first connecting groove 11, and its bottom wall is an inclined wall, fitting against the groove wall of the first connecting groove 11. The side connector 32 includes two connecting parts 321. Each connecting part 321 is located at opposite ends of the side connecting member 32. The connecting shaft 33 is mounted on one connecting part 321 and is rotatably connected to the side stop block 31. A sliding groove 12 is provided on one side of the processing base 1. The other connecting part 321 is slidably and rotatably connected to the sliding groove 12. The other connecting part 321 slides in the height direction of the processing base 1. The support block 41 is located at the bottom of the processing base 1, and the adapter shaft 34 is rotatably mounted on one side of the support block 41. The mounting plate 35 is fixedly connected to the adapter shaft 34 and rotates towards or away from the processing base 1. The cylinder 36 is mounted on the mounting plate 35, and the telescopic end of the cylinder 36 is rotatably connected to the connecting shaft 33. The plasma spraying equipment 8 is located on one side of the processing base 1 and is used to spray fireproof coating on the refined steel 10.

[0054] In practice, the heights of the clamping block 2 and the side stop block 31 are both adapted to the height of the refined steel 10.

[0055] In practice, the refined steel 10 is dragged onto the processing seat 1, and the clamping block 2 is adjusted to slide towards the refined steel 10. With the help of the side stop block 31, the refined steel 10 is clamped. Fireproof coating is sprayed onto the refined steel 10 by the plasma spraying equipment 8 to complete the spraying treatment on one side of the refined steel 10. When it is necessary to adjust the flipping of the refined steel 10, the clamping block 2 is slid away from the refined steel 10, and the cylinder 36 is retracted. At this time, the mounting plate 35 rotates, the cylinder 36 slides along the mounting plate 35, the telescopic end of the cylinder 36 rotates along the connecting shaft 33, the lower connecting part 321 of the side connecting piece 32 rotates and slides downward, the cylinder 36 pulls the side connecting piece 32 outward and downward, so that the side stop block 31 is disengaged from one side of the refined steel 10, thereby allowing the refined steel 10 to flip. After the refined steel 10 flips, the clamping block 2 is slid and the cylinder 36 is extended to complete the re-clamping treatment of the refined steel 10. The flipped refined steel 10 is then sprayed with fireproof coating by the plasma spraying equipment 8.

[0056] The plasma spraying equipment of this application clamps the refined steel 10 from one side with a side stop 31 in conjunction with a clamping block 2. This allows the refined steel 10 to be adjusted and flipped after the side stop 31 is disengaged from one side. By setting the bottom wall of the side stop 31 to be an inclined wall, the side stop 31 can rotate and move downwards at the same time. This facilitates the adjustment of the rotation and downward movement of the side stop 31 by the cylinder 36, eliminating the need for two separate drive components to drive the rotation and sliding of the refined steel 10, thus making it convenient to use.

[0057] In a preferred embodiment, the top of the support block 41 is provided with a support groove 411, which is used to support the side block 31. In the sliding direction of the pressing block 2, the distance between the lower connecting part 321 and the adapter shaft 34 is L1, and the distance between the two connecting parts 321 is L2, where L1 < L2.

[0058] This design allows the cylinder 36 to pull and support the side block 31 on the support groove 411 via the side connector 32. The support groove 411 supports the side block 31, reducing the workload of the cylinder 36 and making it easier to use.

[0059] In a preferred embodiment, a support leg 42 is also included, wherein the support leg 42 is disposed at the bottom of the machining base 1 and located on the side of the machining base 1 away from the support block 41, for supporting the machining base 1, and the bottom end of the support block 41 is flush with the bottom end of the support leg 42.

[0060] In practice, the support legs 42 work in conjunction with the support blocks 41 to support the machining base 1, so that the support blocks 41 can simultaneously support the machining base 1, making it convenient to use.

[0061] In a preferred embodiment, the device further includes a first mounting member 51, a transfer roller 52, an assembly 53, and a sliding member 54. The first mounting member 51 is disposed on the processing base 1, and the transfer roller 52 is rotatably connected to the first mounting member 51. The assembly 53 is disposed on the transfer roller 52, and the sliding member 54 is slidably connected to the assembly 53. The sliding member 54 is hinged to the clamping block 2.

[0062] Specifically, when it is necessary to adjust the pressure block 2 to slide away from the refined steel 10, adjust the rotation of the transfer roller 52. The transfer roller 52 drives the assembly 53 to rotate, and the sliding joint 54 slides along the assembly 53, thereby completing the sliding adjustment of the pressure block 2.

[0063] It also includes a first drive motor 55 and a pressing component 56. The first drive motor 55 is mounted on the first mounting component 51 and is used to drive the transfer roller 52 to rotate. The pressing component 56 is a bent component, mounted on the transfer roller 52 and located on the side of the transfer roller 52 away from the mounting component 53, and is used to extrude the top side of the refined steel 10.

[0064] By setting the mounting part 53 and the pressing part 56 on opposite sides of the transfer roller 52, when the adjusting clamping block 2 slides away from the fine steel 10 to adjust the rotation of the fine steel 10, the pressing part 56 moves towards the fine steel 10 simultaneously and pushes the top side of the fine steel 10. The pressing part 56 can assist the user in flipping the fine steel 10, making it convenient to use.

[0065] In a preferred embodiment, the system further includes a second mounting member 61, a drive roller 62, a drive belt 63, and a second drive motor 64. The second mounting member 61 is mounted on the processing base 1, and two drive rollers 62 are rotatably connected to the second mounting member 61. The drive belt 63 is connected to the two drive rollers 62 and passes around the top of the processing base 1 for contact with the refined steel 10. The second drive motor 64 is mounted on the second mounting member 61 for driving one drive roller 62 to rotate.

[0066] By setting up a drive belt 63, when performing surface spraying treatment on spherical or cylindrical refined steel 10, the second drive motor 64 can be started simultaneously during spraying. At this time, the second drive motor 64 drives the drive belt 63 to rotate through the drive roller 62. The drive belt 63 drives the refined steel 10 to rotate through friction, thereby completing the rapid flipping treatment of the refined steel 10. This allows the plasma spraying equipment 8 to perform surface spraying treatment on the refined steel 10 during the flipping process, improving spraying efficiency and making it convenient to use.

[0067] In specific implementation, the top of the processing base 1 is provided with a second connecting groove 13, and the bottom of the processing base 1 is provided with two connecting holes 14. The connecting holes 14 are connected to the second connecting groove 13, and the drive belt 63 passes through the connecting holes 14 and is located inside the second connecting groove 13.

[0068] By setting the drive belt 63 to be connected to the inside of the second connecting groove 13, there is no need to set the drive roller 62. At the same time, the rotational stability of the drive belt 63 is increased under the constraint of the groove wall of the second connecting groove 13.

[0069] In a preferred embodiment, a support 7 is also included, wherein the support 7 is disposed on one side of the processing seat 1 for supporting the refined steel 10, and the top surface of the support 7 is formed with a first support surface 71 and a second support surface 72, and the lengths of the first support surface 71 and the second support surface 72 are both greater than or equal to the length of the refined steel 10.

[0070] Specifically, during the surface spraying of the refined steel 10, the refined steel 10 is supported on the first support surface 71. During the flipping process of the refined steel 10, the refined steel 10 can be rotated to be located on the second support surface 72.

[0071] This design allows the support seat 7 to continuously support the delicate steel 10 during the flipping process, thus improving the stability of the delicate steel 10 during flipping.

[0072] In a preferred embodiment, the plasma spraying equipment 8 includes a first slide rail 81, a second slide rail 82, a first connecting frame 83, an adapter 84, and a plasma spray gun 85. The second slide rail 82 is connected to the slider of the first slide rail 81 via the first connecting frame 83, and the adapter 84 is rotatably connected to the slider of the second slide rail 82. The slider of the first slide rail 81 moves in the width direction of the processing base 1, and the slider of the second slide rail 82 moves in the length direction of the processing base 1. The adapter 84 is connected to the plasma spray gun 85 via the second connecting frame 86, which extends in the width direction of the processing base 1. The plasma spray gun 85 is used to spray fire-retardant coating onto the refined steel 10.

[0073] In practice, by adjusting the sliders of the first slide rail 81 and the second slide rail 82, the plasma spray gun 85 moves in the X / Y direction, and the plasma spray gun 85 completes the spraying treatment of the fine steel 10.

[0074] By setting up an adapter 84, when it is necessary to flip the refined steel 10, the adapter 84 can be adjusted to rotate, and the adapter 84 drives the plasma spray gun 85 to move upward, so that the plasma spray gun 85 can not hinder the flipping process of the refined steel 10, making it convenient to use.

[0075] This invention also proposes a method for plasma spraying a thin-film fire-retardant coating for refined steel, which is completed using the aforementioned plasma spraying equipment for thin-film fire-retardant coatings for refined steel, and includes the following steps:

[0076] Step 1: Place the refined steel 10 onto the machining base 1;

[0077] Step 2: Adjust the clamping block 2 to slide closer to the refined steel 10 to complete the clamping process of the refined steel 10;

[0078] Step 3: Apply fire-retardant coating to 8 pairs of refined steel using a plasma spraying device;

[0079] Step 4: Adjust the pressing block 2 to slide away from the fine steel 10, and adjust the cylinder 36 to retract. At this time, the mounting plate 35 rotates, the cylinder 36 slides, the telescopic end of the cylinder 36 rotates along the connecting shaft 33, and the cylinder 36 pulls the side connecting piece 32 outward and downward, so that the side stop block 31 is separated from one side of the fine steel 10.

[0080] Step 5: After adjusting the flipping of the fine steel 10, adjust the sliding of the clamping block 2 and the extension of the cylinder 36 to complete the re-clamping of the fine steel 10.

[0081] Step Six: Apply fire-retardant coating to the flipped refined steel 10 using plasma spraying equipment 8.

The plasma spray gun is used to spray fire-retardant coating onto refined steel.

10. A method for plasma spraying a thin-film fire-retardant coating on refined steel, characterized in that: The process is completed using the plasma spraying equipment for fine steel thin-film fireproof coating as described in any one of claims 1 to 9, and includes the following steps: S1. Place the fine steel drag on the machining seat; S2. Adjust the clamping block to slide closer to the refined steel to complete the clamping process of the refined steel; S3. Apply fire-retardant coating to refined steel using plasma spraying equipment; S4. Adjust the clamping block to slide away from the refined steel, and adjust the cylinder to retract. The cylinder pulls the side connector outward and downward, so that the side stop block is separated from one side of the refined steel. S5. After adjusting the flipping of the refined steel, adjust the sliding of the clamping block and the extension of the cylinder to complete the re-clamping of the refined steel. S6. Apply fire-retardant coating to the turned-over refined steel using plasma spraying equipment.
