[0030] In order to make the purposes, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0031] Please refer to Figures 1 to 5 The embodiment is a multi-link iron ladle capping device, comprising:

[0032] The iron ladle 11 has a bottom surface fixed with a base 12, and the base 12 has two sides rotatably installed with a connecting rod 13, and the upper end of the connecting rod 13 is fixed with a top cover 14.

[0033] The iron ladle 11 is a container for holding and transporting high-temperature liquid metal.

[0034] The shielding assembly comprises a sliding groove 21, a motor 22, a lead screw 25, a movable ring 26, and a baffle 27. The sliding groove 21 is formed on one side of the upper end of the iron ladle 11, the motor 22 is fixed on one side of the outer side of the iron ladle 11, the lead screw 25 is fixed on the output end of the motor 22, the movable ring 26 is threaded through the outer surface of the lead screw 25, one side of the movable ring 26 is fixed with the baffle 27, and the baffle 27 is slidably installed inside the sliding groove 21.

[0035] The sliding groove 21 is used to install the baffle 27, so that the baffle 27 can move in the sliding groove 21, thereby realizing the opening and closing of the top of the iron ladle 11. The motor 22 serves as a power source and drives the lead screw 25 to rotate to drive the movement of the movable ring 26 and the baffle 27. The lead screw 25 converts the rotary motion of the motor 22 into linear motion. The movable ring 26 moves on the lead screw 25 with the rotation of the lead screw 25, thereby driving the baffle 27 to move correspondingly.

[0036] One side of the baffle 27 is fixed with a limiting ring 271, one side of the fixed frame 23 is fixed with a limiting rod 28, the limiting ring 271 is slidably threaded through the outer surface of the limiting rod 28, the outer surface of the baffle 27 is formed with a square groove 272 on both sides, the lead screw 25 is fixed with a fixed plate 29 on one side of the limiting rod 28, and one side of the fixed plate 29 is fixed with the outer surface of the iron ladle 11.

[0037] The square groove 272 is located on both sides of the iron ladle 11, which facilitates the internal molten iron heat dissipation and pressure release, and avoids the safety hazards caused by excessive pressure in the sealed space.

[0038] The fixed frame 23 is used to support the motor 22 and the connecting plate 24, and ensures the stability of the motor 22. The limiting ring 271 is used in cooperation with the limiting rod 28 on the fixed frame 23 to limit the movement range of the baffle 27. The fixed plate 29 is fixed on one side of the lead screw 25 and the limiting rod 28, and one side of the fixed plate 29 is fixed with the outer surface of the iron ladle 11, which is used to enhance the stability of the entire structure.

[0039] Working principle:

[0040] When transporting the molten iron, the staff first starts the motor 22 through the external controller, the motor 22 drives the screw rod 25 to rotate, the screw rod 25 synchronously drives the movable ring 26 to move on the surface of the screw rod 25, when the motor 22 rotates clockwise, the movable ring 26 drives the baffle 27 to move to the rear side, the baffle 27 moves backward in the sliding groove 21, opens the top of the ladle 11, then controls the connecting rod 13 to open to both sides through the controller, completely opens the top of the ladle 11, needs to close the ladle 11, the motor 22 rotates counterclockwise, drives the screw rod 25 to rotate counterclockwise, the screw rod 25 drives the movable ring 26 to move to the front side, closes the top of the ladle 11, and then closes the top cover 14 on both sides, double closure, no gap in the top of the ladle 11;

[0041] This step can effectively prevent the molten iron from spilling out and impurities from entering the outside, and improve the safety of the transportation process.

[0042] Please refer to Figures 1 to 5 The embodiment is based on the above embodiment, further comprising:

[0043] The scraping assembly comprises a fixed frame 31, a mounting groove 32 and a spring 33, the fixed frame 31 is fixed on one side of the connecting plate 24, the mounting groove 32 is opened on the upper surface of the fixed frame 31 and the connecting plate 24, and the spring 33 is fixed in the mounting groove 32, the upper end of the spring 33 is fixed with a scraper 34, the top of the scraper 34 is triangular, and the top end of the scraper 34 is in contact with the lower surface of the baffle 27.

[0044] The mounting groove 32 is used for accommodating the spring 33, the main function of the spring 33 is to provide elastic force, so that the scraper 34 can be closely attached to the lower surface of the baffle 27, the top of the scraper 34 is triangular, which helps to improve the scraping efficiency, because the tip of the triangle can more easily scrape the condensate on the surface of the baffle 34, and the top end of the scraper 34 is in contact with the lower surface of the baffle 27, when the baffle 27 moves, the scraper 27 keeps in contact with the baffle 27 under the action of the elastic force of the spring 33, effectively scraping the water vapor on the surface of the baffle 27.

[0045] Working principle:

[0046] When the baffle 27 moves, the scraper 34 is pushed upward under the action of the elastic force of the spring 33, so that the scraper 34 is in contact with the lower surface of the baffle 27, and when the baffle 27 is outside, water vapor will cover the surface of the baffle 27, in order to reduce the water vapor entering the inside of the ladle 11, the scraper 34 scrapes the water vapor condensed on the surface of the baffle 27.

[0047] This step scrapes the water vapor on the surface of the baffle 27, reduces the influence of the water vapor on the temperature of the molten iron, and helps to keep the temperature of the molten iron stable.
