Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a turnable alloy hopper for a converter. Background Art

[0002] In the process of steelmaking, when the molten iron condition is not good during the production process of the converter, a certain amount of alloy is often added before oxygen blowing to improve the oxygen blowing effect. During the process of adding the alloy, the alloy is often loaded into the alloy hopper, then turned over into the scrap steel tank, and then added into the converter. However, when the existing alloy hoppers are used for adding raw materials, there are often some problems:

[0003] The operation is cumbersome and the safety is poor. When the existing alloy hoppers are used for adding raw materials, due to the original alloy hoppers being heavy and inconvenient to use, and when the discharge hopper of the alloy hopper dumps materials downward, the discharge hopper often swings continuously, and during the swinging process, the alloy may spill out of the converter, resulting in poor reliability in use.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment

[0023] A turnable alloy hopper for a converter. This embodiment is based on plastic products with a density greater than that of water. In order to achieve the cleaning of impurities, as Figures 1-4 shown, it includes a C-shaped base seat 1. Both outer walls on the two sides of the top of the C-shaped base seat 1 are welded with fixed brackets 2, and the top of the fixed brackets 2 is rotatably provided with a rotating shaft 3 through a bearing. On the outer walls of the opposite sides of the two rotating shafts 3, a hopper housing 4 is welded. Both sides of the hopper housing 4 are welded with support shafts 5. Both outer walls at the two ends of the C-shaped base seat 1 are provided with sliding grooves 7, and a sliding seat 8 is slidably arranged on the inner wall of the sliding grooves 7. A spring 11 is welded on one outer wall of the sliding seat 8, and a support drag block 12 is welded on the top outer wall of the sliding seat 8. A knocking block 13 is welded on one outer wall of the support drag block 12, and damping spring shock absorbers 14 are arranged at both ends of one outer wall at the bottom of the C-shaped base seat 1. A positioning block 15 is welded at the end of the damping spring shock absorber 14, and a positioning slot 16 is opened on the positioning block 15;

[0024] By setting the micro-eccentric hopper housing 4 that can be automatically turned, after removing the support of the support shaft 5, the alloy inside the hopper housing 4 can be quickly poured out by using the swing of gravity, so as to complete rapid unloading. And after swinging to the bottom, the clamping rod 17 is clamped on the positioning block 15, and the hopper housing 4 can be quickly clamped and fixed, reducing unnecessary swinging, so as to achieve safe feeding.

[0025] Both outer walls at the two ends of the bottom of the C-shaped base seat 1 are welded with slot branch pipes 6, and the size of the slot branch pipes 6 is adapted to the size of the forklift fork. The sliding grooves 7 are provided with equally spaced limit holes 9, and one side of the sliding seat 8 is provided with a through limit hole 9. A limit insertion rod 10 is inserted and fixed in the inner wall of the limit hole 9, and the limit hole 9 and the limit insertion rod 10 form a fastening fit;

[0026] On one outer wall of the hopper housing 4, symmetrically distributed clamping rods 17 are welded, and grooves 18 are formed on the outer walls of the ends of the clamping rods 17 away from the hopper housing 4.

[0027] On the inner wall of the bottom of the groove 18, a compression spring 19 is welded, and on the outer wall of the top of the compression spring 19, a trapezoidal clamping block 20 is welded;

[0028] During the process of rotating and tilting the hopper housing 4, the elastic potential energy of the spring 11 is utilized for stretching, so that the support drag block 12 and the support shaft 5 are quickly separated. This not only has simple operation but also can perform safe feeding.

[0029] When this embodiment is in use, first move the sliding seat 8, so that the spring 11 is in a stretched state, so that the support drag block 12 jacks up the support shaft 5. After that, insert and fix the limit insertion rod 10 into the limit hole 9. After completion of the fixation, pour the alloy to be fed into the hopper housing 4. Then, insert and fix the fork ruler of the forklift into the bottom slot branch pipe 6, so as to lift the hopper housing 4 filled with alloy and move it to the converter to be fed. After moving to a suitable position, pull the limit insertion rod 10, so that the spring 11 continuously contracts, so as to pull the support drag block 12 backward, realizing the separation of the support shaft 5 and the support drag block 12. When the support shaft 5 loses support, due to the micro-eccentric structure of the hopper housing 4, the hopper housing 4 will rotate around the rotation shaft 3. When the material opening of the hopper housing 4 rotates to the bottom, its clamping rod 17 will quickly be inserted into the positioning card slot 16. Due to the cooperation of the compression spring 19 and the trapezoidal clamping block 20, the trapezoidal clamping block 20 will be clamped and fixed in the positioning card slot 16, so as to cooperate with the damping spring shock absorber 14, which can avoid the backswing of the hopper housing 4, so that the alloy can be quickly and safely poured out to complete the feeding.
