Abstract
Description
Technical Field
[0001] The present application relates to the technical field of converter steelmaking, in particular to a scrap steel tank. Background Art
[0002] With the increase of environmental awareness, the steel industry has reduced carbon emissions and improved resource utilization. Refractory steelmaking in converters can reduce dependence on raw materials such as iron ore, reduce energy consumption and greenhouse gas emissions. Therefore, refractory steelmaking in converters is one of the important directions for the sustainable development of the steel industry, and is of great significance for energy conservation, emission reduction, resource utilization and environmental protection.
[0003] The converter production of steel plants usually requires adding molten iron and scrap steel to the converter. Due to the different types of scrap steel, the order of adding in the scrap steel trough is random, which often causes large friction between the scrap steel and the scrap steel trough. Even after the scrap steel trough is lifted to a larger angle, the scrap steel still does not slide, and the scrap steel cannot be added to the converter. In order to add the scrap steel to the converter, the staff often needs to use the scrap steel trough to hit the converter mouth so that the scrap steel slides toward the mouth and completes the addition of the scrap steel. This also has a great impact on the converter mouth, such as: causing the converter mouth to rupture and circulating cooling water to flow out. At the same time, it will also cause major safety accidents and economic losses. Utility Model Content

[0056] In the related art, converter production usually requires adding molten iron and scrap steel to the converter. Due to the different types of scrap steel, the order of adding in the scrap steel trough is random, which often causes large friction between the scrap steel and the scrap steel trough. Even after the scrap steel trough is lifted to a larger angle, the scrap steel still does not slide, and the scrap steel cannot be added to the converter. In order to add scrap steel to the converter, the staff often needs to use the scrap steel trough to hit the converter mouth so that the scrap steel slides toward the mouth and completes the addition of scrap steel. This also has a great impact on the converter mouth, such as: causing the converter mouth to rupture and circulating cooling water to flow out. At the same time, it will also cause major safety accidents and economic losses.
[0057] To this end, the present application provides a scrap steel trough, which includes a trough body 1, a first arm 11, a second arm 12 and a push plate 2; wherein the trough body 1 has an inner cavity 13 capable of holding materials and a discharge port 14 communicating with the inner cavity 13; the first arm 11 is hinged to the trough body 1 through a first axis 111; the second arm 12 is hinged to the trough body 1 through a second axis 121, and the second arm 12 is used to drive the trough body 1 to rotate around the first axis 111, and enable the trough body 1 to rotate between a first position and a second position, and when the trough body 1 is in the second position, the material 3 in the inner cavity 13 can be poured out through the discharge port 14; the push plate 2 is at least partially disposed in the inner cavity 13, and the push plate 2 is configured as follows: when the trough body 1 rotates from the first position to the second position, the push plate 2 is used to push the material 3 in the inner cavity 13 to move toward the discharge port 14. The push plate pushes the material in the inner cavity to move toward the discharge port, thereby solving the technical problem in the prior art that the scrap steel trough hits the converter port, causing the converter port to break and the circulating cooling water to flow out.
[0058] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.
[0059] To facilitate the description of the following embodiments, the present application takes a scrap steel trough for holding and dumping scrap steel as an example for explanation.
[0060] For reference Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the scrap steel tank provided in some embodiments of the present application when it is in the first position, Figure 2 A cross-sectional view of a scrap steel trough provided for some embodiments of the present application.
[0061] In an embodiment of the present application, a scrap steel tank is provided. The scrap steel tank comprises a tank body 1. The tank body 1 is used to hold a material 3. The material 3 includes but is not limited to scrap steel in the embodiment of the present application.
[0062] Specifically, the tank body 1 has an inner cavity 13 capable of containing the material 3, and a discharge port 14 communicating with the inner cavity 13. The specific structure of the discharge port 14 is not limited in the embodiment of the present application, and the structure can be a structure that enables the material 3 to be poured from the inner cavity 13 to the outside of the tank body 1. For example: an opening with a circular structure, an opening with a square structure, an opening with a semicircular structure, etc. In the embodiment of the present application, the specific structure of the discharge port 14 is an opening with a semicircular structure as an example for explanation.
[0063] The scrap steel tank further comprises a first arm 11. The function of the first arm 11 is to lift or lower the height of a part of the tank body 1 and to carry the tank body 1. Specifically, the first arm 11 is hinged to the tank body 1 through a first shaft 111.
[0064] During the operation of the scrap steel tank, the material 3 is added to the inside of the tank body 1 by using a magnetic suspension device. The first arm 11 is lifted upward in the vertical direction, so that the tank body 1 is tilted as a whole. At this time, the direction of the discharge port 14 is tilted upward or vertically upward, so that the material 3 can be kept away from the discharge port 14 in the inner cavity 13, and the material 3 is prevented from slipping out of the discharge port 14 during the process of transporting the material 3 in the scrap steel tank.
[0065] The scrap steel tank further comprises a second arm 12. The second arm 12 is used to lift or lower the height of a part of the tank body 1 and to carry the tank body 1. Specifically, the second arm 12 is hinged to the tank body 1 through a second shaft 121.
[0066] refer to Figure 3 , Figure 3 A schematic diagram of the structure of the scrap steel trough provided in some embodiments of the present application when it is in the second position.
[0067] The second arm 12 is also used to drive the slot body 1 to rotate around the first axis 111 and enable the slot body 1 to rotate between the first position and the second position.
[0068] Specifically, during the operation of the scrap steel tank, the second arm 12 is lifted upward in the vertical direction, and the first arm 11 is moved downward in the vertical direction or remains stationary. Then, the tank body 1 rotates around the first axis 111 .
[0069] When the trough body 1 is in the second position (i.e., the height of the end of the trough body 1 close to the second arm 12 is higher than the height of the end of the trough body 1 close to the first arm 11 ), the material 3 in the inner cavity 13 can be poured out through the discharge port 14 .
[0070] refer to Figure 4 , Figure 4A schematic diagram of the structure of a push plate in a scrap steel trough provided in some embodiments of the present application.
[0071] The scrap steel trough further comprises a push plate 2. The function of the push plate 2 is to push the material 3 in the inner cavity 13 to move toward the discharge port 14.
[0072] Specifically, the push plate 2 is at least partially disposed in the inner cavity 13. Among them, the push plate 2 is at least partially disposed in the inner cavity 13 in the embodiment of the present application specifically means that the push plate 2 is disposed in its entirety in the inner cavity 13 or a portion of the structure of the push plate 2 is disposed in the inner cavity 13. In the embodiment of the present application, the push plate 2 is partially disposed in the inner cavity 13 as an example for description.
[0073] The push plate 2 is configured such that when the tank body 1 rotates from the first position to the second position, the push plate 2 pushes the material 3 in the inner cavity 13 to move toward the discharge port 14 .
[0074] During the operation of the scrap steel tank, a magnetic suspension device or the like is used to add the material to the position between the push plate 2 and the discharge port 14 in the tank body 1. The first arm 11 is lifted upward in the vertical direction, and the second arm 12 is moved downward in the vertical direction or remains stationary, so that the tank body 1 is tilted as a whole. At this time, the discharge port 14 is oriented upward or vertically upward, so that the material 3 can slide in the inner cavity 13 to a position away from the discharge port 14 and close to the push plate 2, thereby preventing the material 3 from slipping out of the discharge port 14 during the process of transporting the material 3 in the scrap steel tank.
[0075] After the tank body 1 is moved to above the converter furnace mouth, the first arm 11 remains stationary or moves downward in the vertical direction, and the second arm 12 is lifted upward in the vertical direction, so that the tank body 1 is tilted as a whole. At this time, the height of the end of the tank body 1 close to the second arm 12 is higher than the height of the end of the tank body 1 close to the first arm 11, and the direction of the discharge port 14 is tilted downward.
[0076] Since the types of materials 3 added to the converter are different, the order of adding different types of materials 3 into the scrap steel trough is random, which often causes greater friction between the materials 3 and the inner bottom of the trough body 1 of the scrap steel trough. Even after the trough body 1 is lifted to a larger angle, the materials 3 still do not slide, and thus the materials 3 cannot be added to the converter.
[0077] The push plate 2 is configured such that when the tank body 1 rotates from the first position to the second position, the push plate 2 pushes the material 3 in the inner cavity 13 to move toward the discharge port 14. External force is applied to the material 3 on the inner bottom of the tank body 1 of the scrap steel tank, thereby overcoming the friction between the material 3 and the inner bottom of the tank body 1 of the scrap steel tank, so that the static friction between the material 3 and the inner bottom of the tank body 1 of the scrap steel tank is converted into sliding friction, and then the material 3 moves toward the discharge port 14 until it falls into the converter.
[0078] In the embodiment of the present application, when the tank body 1 is in the first position, the discharge port 14 is arranged in a horizontal direction or in an inclined upward direction or in a vertical upward direction.
[0079] When the tank body 1 is in the second position, the discharge port 14 is arranged in an inclined downward direction or a vertically downward direction.
[0080] In the embodiment of the present application, the push plate 2 is hinged to the trough body 1 via the third shaft 23 , so that the push plate 2 can rotate relative to the trough body 1 .
[0081] Specifically, the push plate 2 has a push end 21 close to the inner bottom of the inner cavity 13 and a connection end 22 protruding from the inner cavity 13. The push end 21 is used to exert force on the material 3, so that the static friction between the material 3 and the inner bottom of the trough body 1 of the scrap steel trough is converted into sliding friction, and then the material 3 moves toward the discharge port 14 until it falls into the converter.
[0082] The connection end 22 is fixedly connected with a force-bearing portion 24 .
[0083] In the process of the trough body 1 rotating from the first position to the second position, the trough body 1 is transformed from the position where the height of the end near the second arm 12 is lower than or equal to the height of the end near the first arm 11 to the position where the height of the end near the second arm 12 is higher than the height of the end near the first arm 11, and the trough body 1 rotates as a whole. Since the push plate 2 can rotate relative to the trough body 1, the force-bearing part 24 fixed to the connecting end 22 in the push plate 2 is blocked on the side of the second arm 12 away from the discharge port 14, and the second arm 12 only moves vertically upward or downward without tilting, so the force-bearing part 24 remains unchanged in the vertical direction after being blocked, and even if there is an error, it is within the allowable error range, and then the connecting end 22 and the push end 21 connected to the force-bearing part 24 remain unchanged in the vertical direction, and even if there is an error, it is within the allowable error range. Then, the push plate 2 rotates relative to the trough body 1 around the third axis 23, and the push end 21 can push the material 3 in the inner cavity 13 to overcome the friction and move toward the discharge port 14.
[0084] Specifically, a side of the push plate 2 facing the discharge port 14 and a side of the force-bearing portion 24 facing the second arm 12 are in the same plane.
[0085] refer to Figure 5 , Figure 5 A side view of a pushing end in a scrap steel chute provided in some embodiments of the present application.
[0086] In the embodiment of the present application, a push rod 15 is arranged on the inner wall of the tank body 1. The function of the push rod 15 is to prevent the push end 21 from rotating to the side away from the material 3.
[0087] Specifically, the pushing end 21 has a first surface 211 and a second surface 212 that are arranged opposite to each other.
[0088] The first surface 211 faces the discharge port 14 . When the push plate 2 rotates relative to the tank body 1 around the third axis 23 , the first surface 211 contacts the material 3 and pushes the material 3 to move.
[0089] The second surface 212 faces the push rod 15 , and the push rod 15 can exert a force on the second surface 212 to prevent the pushing end 21 from rotating toward a side away from the material 3 .
[0090] In the embodiment of the present application, the tank body 1 has a rear wall 16 arranged opposite to the discharge port 14 .
[0091] Specifically, one end of the push rod 15 is fixed on the rear wall 16 , and the other end of the push rod 15 is extended toward the discharge port 14 .
[0092] The length of the push rod 15 is the distance between the third axis 23 and the rear wall 16 .
[0093] When the tank body 1 is in the first position, the other end of the push rod 15 abuts against the second surface 212 .
[0094] By setting the length of the push rod 15 to be the distance between the third shaft 23 and the rear wall 16, the rotation angle of the push end 21 to the side away from the material 3 is limited to the maximum extent. On the contrary, if the rotation of the push end 21 to the side away from the material 3 is not limited, the material 3 slides to the position between the push end 21 and the rear wall 16, resulting in that this part of the material cannot be pushed to the discharge port 14 by the push end 21 during the process of the trough body 1 rotating from the first position to the second position.
[0095] During the process of the trough body 1 rotating from the first position to the second position, there is always a gap between the push plate 2 and the inner wall of the trough body 1, so that during the relative rotation of the push plate 2 and the trough body 1, no friction is generated between the push plate 2 and the inner wall of the trough body 1, thereby improving the situation where the push plate 2 and the inner wall of the trough body 1 are damaged due to friction.
[0096] In the embodiment of the present application, a feed port 17 is also provided on the tank body 1. The specific structure of the feed port 17 is not limited in the embodiment of the present application, and it can be a structure that enables the material 3 to be poured from the outside of the tank body 1 into the inner cavity 13. For example: an opening with a circular structure, an opening with a square structure, an opening with a semicircular structure, etc. In the embodiment of the present application, the specific structure of the feed port 17 is an opening with a square structure as an example for explanation.
[0097] Specifically, the feed port 17 is communicated with the inner cavity 13. When the tank body 1 is in the first position, the feed port 17 is arranged in an obliquely upward direction or a vertically upward direction.
[0098] In the embodiment of the present application, the first arm 11 is arranged closer to the discharge port 14 than the second arm 12, so that the inclination angle of the trough body 1 can be adjusted by moving the first arm 11 and the second arm 12 upward or downward in the vertical direction, thereby realizing the pouring of the material 3 in the inner cavity 13.
[0099] There are two first arms 11, and the two first arms 11 are relatively arranged on both sides of the trough body 1, and there are two second arms 12, and the two second arms 12 are relatively arranged on both sides of the trough body 1. Since the material in the trough body 1 is large in volume and heavy in weight, the bearing capacity of the trough body 1 is improved by arranging two first arms 11 relatively arranged on both sides of the trough body 1 and two second arms 12 relatively arranged on both sides of the trough body 1. On the contrary, if one first arm 11 and one second arm 12 on one side are hinged to the outside of the trough body 1, since the material in the trough body 1 is large in volume and heavy in weight, the trough body 1 may be skewed or even disconnected from the first arm 11 and one second arm 12 under the action of gravity, and then fall.
[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
