Description

Technical Field

[0001] The utility model relates to steel metallurgical equipment, in particular to a converter slag filling line device. Background Art

[0002] The converter steel plant has multiple converters. The erosion of the converter lining directly restricts the output. After the traditional furnace repair method pours the slag into the furnace, it can only be accumulated in the center of the furnace. The edge slag line cannot be covered, resulting in a thinner slag line at the edge. Long-term thinness affects the safety of the furnace lining. Therefore, designing a hopper that can thicken the edge slag line when pouring slag is a problem that needs to be solved at present. Summary of the Invention

[0003] In response to the above problems, the utility model provides a converter slag line filling device, which can avoid the problem that the slag line in the middle of the furnace is thick and the slag line at the edge is thin. The specific solution is as follows:

[0004] A converter slag feeding line device comprises a long strip hopper, the top of the hopper is open, a discharge port is provided at one end along the length direction of the hopper, and the other end is a closed end. A plurality of baffles for limiting the discharge speed are sequentially arranged between the closed end and the discharge port, and a gap is left between the baffle and the bottom plate of the hopper for the slag to pass through. The device also comprises two guide plates forming a V-shaped structure, the tip of the V-shaped structure is adjacent to the baffle at the discharge port, and the two guide plates extend from the tip to the end of the discharge port, respectively, and form two discharge channels with the side plates on both sides of the hopper.

[0005] Furthermore, the height of the guide plate is greater than the height of the gap.

[0006] Furthermore, the guide plates are elastic metal plates, a support plate is provided between the two guide plates, and springs are respectively connected between the support plate and the two guide plates.

[0007] Furthermore, a V-shaped groove for limiting the displacement of the guide plate is provided at the bottom plate corresponding to the guide plate, and a screw fixedly connected to the tip of the V-shaped groove is provided at the tip of the guide plate.

[0008] Furthermore, an arc-shaped chute is provided on the bottom plate at the discharge port, and pulleys slidably connected to the arc-shaped chute are provided at the bottoms of the two guide plates.

[0009] Furthermore, a gap is left between the guide plate and the bottom plate through screw support, and the height of the gap is equal to the height difference between the pulley and the arc-shaped sliding groove.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The utility model installs a guide plate at the hopper outlet to allow the slag to be poured out along both sides of the hopper outlet, thus avoiding the problem of the slag being concentrated in the center of the furnace bottom, which leads to a thin slag line at the edge;

[0012] 2. The utility model reduces the width of the discharge port of the hopper by setting a guide plate, thereby reducing the discharge speed. By moving the hopper, the slag at the bottom of the furnace can be evenly distributed.

[0013] 3. The utility model sets a support plate between the two guide plates, and connects springs between the support plate and the two guide plates. When the extrusion force of the slag on the discharge channel is too large, the channel is supported by the springs. Even if the guide plates are deflected inward due to the pressure, the pressure is reduced after the slag passes through, and the guide plates can be reset by the springs.

[0014] 4. The utility model can reduce the friction between the guide plate and the bottom plate by arranging a slider at the bottom of the guide plate, thereby preventing the bottom plate from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments.

[0021] Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the utility model.

[0022] In the description of the utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to have a specific orientation, are constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the utility model based on the specific circumstances. Example 1

[0024] like Figure 1 As shown, a converter slag feeding line device includes a long, open-top hopper 1 with a discharge port at one end along its length and a closed end at the other. Lugs for docking slings are located on either side of the hopper 1. A plurality of baffles 2 for limiting the discharge rate are located between the closed end and the discharge port. A gap is left between the baffles 2 and the bottom plate 4 of the hopper 1 for slag to pass through. The device also includes two guide plates 5 forming a V-shaped structure. The tip 6 of the V-shaped structure is adjacent to the baffle 2 at the discharge port. The two guide plates 5 extend from the tip 6 to the end of the discharge port and form two discharge channels with the side plates 3 of the hopper 1. During the slag dumping process, the hopper 1 is controlled to move back and forth left and right by the slings to evenly distribute the slag at the bottom of the furnace. Example 2

[0025] like Figure 1 As shown, the guide plates 5 are elastic metal plates. A support plate 10 is provided between the two guide plates 5. Springs 11 are connected between the support plate 10 and the two guide plates 5. When the slag exerts too much pressure on the discharge channel, the springs 11 support and maintain the channel. Even if the guide plates 5 deflect inward due to the pressure, the pressure decreases after the slag passes through, and the guide plates 5 can be reset by the springs 11. Example 3

[0026] like Figure 2As shown, the bottom plate 4 is provided with a V-shaped groove corresponding to the guide plate 5 for limiting the displacement of the guide plate 5, and the tip 6 of the guide plate 5 is provided with a screw 7 fixedly connected to the tip of the V-shaped groove. Figure 3 As shown, an arcuate chute 9 is provided at the discharge port of the bottom plate 4, and pulleys 9-1 are provided at the bottom of the two guide plates 5, which are slidably connected to the arcuate chute 9. Screws 7 are used to support the guide plates 5 and the bottom plate 4, so that a gap is left between the guide plates 5 and the bottom plate 4. The height of the gap is equal to the height difference between the pulley 9-1 and the arcuate chute 9.

[0027] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention 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 make equivalent replacements for some of the technical features therein. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
