Description

Technical Field

[0001] This utility model belongs to the technical field of steelmaking equipment, and in particular relates to a feeding device for steelmaking. Background Technology

[0002] A feeding device is a device that moves materials from one location to another. In the steelmaking process, it is necessary to use a feeding device to feed materials such as carbon powder into the steel furnace for metallurgical operations. Due to the varying sizes of the materials, there may be too much or too little material during the feeding process, thus affecting the quality of the finished steel product. Application No. 202420582654.9 discloses a feeding device for a vacuum furnace in steelmaking, which is equipped with a crushing box to crush the materials before conveying them into the steel furnace. This can, to some extent, avoid problems with the quality of the finished product caused by the varying sizes of the materials. However, the materials crushed by the crushing box inevitably have some large pieces, and directly feeding them into the steel furnace will also affect the quality of the finished product.

[0020] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0021] like Figures 1-3 The steelmaking feeding device shown includes: a material box 1, a collection box 2 disposed on one side of the material box 1, and a feeding mechanism 3 communicating with the material box 1; the material box 1 is used to inject material crushed by a crusher. The top of the material box 1 is provided with a feed inlet 4 communicating with the crusher, and the feed inlet 4 is connected to the discharge outlet 6 of the crusher. In this embodiment, the feed inlet 4 is located on one side of the top of the material box 1; the inside of the material box 1 is provided with a filter screen 5 corresponding to the feed inlet 4, and the discharge outlet 6 is provided on the side wall near the collection box 2, that is, the material crushed by the crusher is filtered by the filter screen 5, and large pieces of material are blocked on the filter screen 5 to prevent them from entering the material box 1; the filter screen 5 is inclined, with its high end connected to the inner top of the material box 1 and its low end connected to the bottom of the discharge outlet 6, and the discharge outlet 6 is connected to the inside of the collection box 2; large pieces of material on the filter screen 5 slide towards the low end of the filter screen 5 under the action of gravity and are discharged from the discharge outlet 6 into the collection box 2.

[0022] Furthermore, to prevent the filtered material from concentrating in the material box 1 below the filter screen 5, the material box 1 is provided with an inclined guide plate 11. The high end of the guide plate 11 is located below the middle of the filter screen 5, and the low end is connected to the side wall of the material box 1. The side wall where the low end of the material box 1 and the guide plate 11 are connected is opposite to the side wall where the discharge port 6 is located. The guide plate 11 is provided with several through-holes 12 penetrating its thickness, such as... Figure 2 As shown. The high end and both ends of the guide plate 11 are connected to the side wall of the material box 1. Specifically, the end of the guide plate 11 can be fixed to the side wall of the material box 1 by bolts, or the guide plate 11 can be welded into the material box 1. The material filtered by the filter screen 5 falls onto the guide plate 11 and falls into the bottom of the material box 1 through the opening 12 on the guide plate 11.

[0023] Furthermore, a conveying mechanism 13 is connected to the collection box 2. The conveying mechanism 13 is used to transport the material inside to the crusher. That is, after large pieces of material blocked by the filter screen 5 fall from the discharge port 6 into the collection box 2, they are conveyed to the crusher for further crushing through the conveying mechanism 13, thus avoiding material waste. In this embodiment, the structure of the conveying mechanism 13 is the same as that of the feeding mechanism 3. To ensure that the material on the filter screen 5 enters the collection box 2 smoothly, the side walls of the collection box 2 and the material box 1 are connected, and the side wall of the collection box 2 is provided with a through groove 10 corresponding to the discharge port 6. The material enters the collection box 2 directly from the discharge port 6 through the through groove 10.

[0024] The feeding mechanism 3 is used to convey the material in the material box 1 into the steel furnace. The feeding mechanism 3 is inclined, with its lower end connected to the lower part of the material box 1, and its upper part is provided with a discharge chute 31 for feeding the material in the material box 1 into the steel furnace. The feeding mechanism 3 includes a feeding pipe 32, an auger 33, and a motor 34. The feeding pipe 32 is inclined, and the motor 34 is mounted on the top through a motor mount. The discharge chute 31 is provided on the upper side wall opposite to the collection box 2, and the auger 33 is provided inside. The rotating shaft of the auger 33 is coaxially connected to the output shaft of the motor. The lower part of the feeding pipe 32 is connected to the collection box 2. The motor 34 is started to drive the auger 33 to rotate, thereby conveying the material in the material box 1 from low to high. When the material reaches the discharge chute 31, it falls into the steel furnace due to gravity.

[0025] In this embodiment, a feeding plate 7 is detachably connected to the outer wall of the feeding mechanism 3. The feeding plate 7 is located below the discharge chute 31 and tilts downward from the position where it is connected to the feeding mechanism 3. The feeding plate 7 is used to feed materials into the steel furnace. On the one hand, the feeding plate 7 can help to transport the materials in the feeding mechanism 3 into the steel furnace more smoothly. On the other hand, it can also reduce the probability of the feeding mechanism 3 being damaged by the high temperature in the steel furnace. Moreover, since the feeding plate 7 is detachably connected to the feeding mechanism 3, when the feeding plate 7 is damaged by the high temperature, it can be replaced, saving costs. Further, the cross-section of the feeding plate 7 is arc-shaped, and its end is provided with an ear plate 8. The feeding mechanism 3 is provided with a fixing plate 9 corresponding to the ear plate 8, and the fixing plate 9 is connected to the ear plate 8 by bolts.
