Description

Technical Field

[0001] This invention belongs to the field of metallurgical equipment technology, specifically relating to a mobile three-coordinate type slag removal device and method for cleaning molten iron residue at the mouth of a molten iron mixing car, which is suitable for cleaning molten iron residue at the mouth of the molten iron mixing car during use. Background Technology

[0002] Molten iron transportation is a crucial step in steel production, typically accomplished using molten iron ladle cars. During transport, slag often forms at the ladle opening due to the cooling and oxidation of the molten iron. This slag not only reduces the effective volume of the ladle car, affecting transportation efficiency, but can also accumulate at the opening, causing blockages and hindering the flow and pouring of molten iron. In severe cases, it can even lead to safety accidents.

[0003] Traditional slag removal methods at the mouth of mixed iron car tanks mainly rely on manual operation, using tools such as hammers to knock off the slag. Some steel companies have also developed fixed slag removal machines, which use a mechanical arm to drive the cutter head to remove slag from the tank mouth by fixing the base. However, manual cleaning and fixed slag removal methods have the following disadvantages: (1) Manual slag removal is labor-intensive, has low cleaning efficiency, and poses significant safety hazards; (2) Fixed slag removal devices are usually installed in fixed positions, with limited range of motion and poor adaptability, making them difficult to adapt to complex slag removal conditions; (3) Fixed slag removal machines have poor flexibility and cannot meet multi-directional slag removal needs, relying solely on a mechanical arm to drive the cutter head for slag removal. Summary of the Invention

[0004] This invention provides a mobile three-coordinate type slag removal device and method for mixing iron car mouths, which can solve the problems of high labor intensity and low efficiency of manual slag removal methods and poor adaptability and flexibility of fixed slag removal devices in the prior art.

By setting up a chassis mechanism, a transverse base, a longitudinal base, an upper hanger, a lifting seat, and a cutter head mechanism, and cooperating with three types of hydraulic cylinders, the cutter head mechanism for cleaning the mouth of the mixed iron car can be moved laterally, longitudinally, and vertically. This allows the cutter head mechanism to clean the slag at the mouth of the mixed iron car from multiple angles and directions, making the slag removal operation more precise and the cleaning efficiency higher. At the same time, compared with the mechanical arm operation in the fixed slag removal device, it is more flexible and adaptable.

[0029] (2) This invention can operate each hydraulic cylinder and motor through automated control, which can effectively reduce human resource input, labor intensity and labor costs. At the same time, this invention can be installed in places such as frames with tracks to meet the on-site slag removal needs. Attached Figure Description

The cutter disc assembly 61 is provided with corresponding horizontal and vertical cutter discs, which facilitates the cleaning of slag from the mixing car mouth when the cutter disc assembly 61 rotates.

The bottom of the transverse base body 21 has a third ear seat 27 that corresponds to each first ear seat 19. The two ends of each transverse hydraulic cylinder 71 are movably connected to the corresponding first ear seat 19 and third ear seat 27. Through the transverse hydraulic cylinder 71 and the transverse guide seats 13 and transverse sliding blocks 23 that slide between the chassis mechanism 1 and the transverse base 2, when the transverse hydraulic cylinder 71 extends or retracts, it can drive the transverse base 2 to move laterally relative to the chassis mechanism 1, thereby realizing the transverse displacement of the cutter head mechanism 6.

[0052] In a preferred embodiment, the transverse base 2 has two second ear seats 26 on both sides of the top transverse end, and multiple pairs of support seats 25 are respectively arranged on the longitudinal sides of the first lifting hole 22.

[0054] Example 2:

[0055] This application provides a method based on the movable three-coordinate mixing car mouth slag cleaning device in Embodiment 1. The movable three-coordinate mixing car mouth slag cleaning device is installed on the frame and track of the corresponding mixing car. The mixing car travels under the frame and track. When the mixing car reaches the area under the frame and track, the cutter head mechanism 6 can be moved to the slag cleaning position by controlling the transverse hydraulic cylinder 71, the longitudinal hydraulic cylinder 72, and the lifting hydraulic cylinder 73, according to the position of the mixing car mouth. Specifically, this includes:

[0056] The horizontal movement of the horizontal movement base 2 is driven to move laterally within the rectangular frame structure of the chassis mechanism 1 by the extension and retraction of the horizontal movement hydraulic cylinder 71, thereby driving the horizontal movement of the cutter head mechanism 6.

[0057] The longitudinal hydraulic cylinder 72 extends and retracts, causing the longitudinal base 3 to move horizontally in the first lifting hole 22 of the transverse base 2, thereby causing the cutter head mechanism 6 to move horizontally in the longitudinal direction.

[0058] The lifting hydraulic cylinder 73 extends and retracts to drive the lifting seat 5 to rise and fall within the second lifting hole 32 of the longitudinal base 3, thereby driving the cutter head mechanism 6 to rise and fall.

[0059] After the cutter head mechanism 6 has completed one or more operations of lateral, longitudinal and lifting displacement and reached the slag cleaning position at the tank opening, the cutter head mechanism 6 is activated to clean the slag.
