Description

Technical Field

[0001] The present application belongs to the technical field of metallurgy, and in particular relates to a covering agent conveying device. Background Art

[0002] In the continuous casting process, in order to ensure the purity of molten steel and prevent secondary oxidation, the molten steel needs to be fully protected and the molten steel inside the tundish needs to be protected by a covering agent. Continuous casting is a continuous process, and the covering agent added to the tundish will be continuously melted and consumed, so the amount of covering agent put into the tundish is huge and continuous.

[0003] In the related art, the most common method used is manual bagging, that is, a person stands near the tundish, holds a bag of covering agent, and puts the bag of covering agent into the tundish. This method requires experienced operators. In the initial pouring process, the demand for covering agent is large, and at least three operators are required to feed the material at the same time.

[0004] The manual bag feeding method is not only labor-intensive and inefficient, but also the operator is close to the tundish during feeding. The operator is very likely to be scalded by the splashing molten steel, causing safety accidents. The operator also needs to endure the high temperature and the large amount of dust generated by the addition of the covering agent, which will cause serious harm to the operator's health in the long run. Utility Model Content

[0005] The present application aims to at least to some extent solve the technical problem of relatively high risk when adding covering agent in the related art. To this end, the present application provides a covering agent conveying device.

[0006] A covering agent conveying device provided in an embodiment of the present application includes:

[0007] A storage table for placing covering agent;

[0008] A transfer rack, one side of which is connected to the storage table, and the height of the side connected to the storage table is higher than the height of the other side, so that the covering agent placed on the transfer rack can be transferred from the side close to the storage table to the side away from the storage table.

[0009] In some embodiments, the transfer rack is rotatably connected to the storage platform around a first horizontally disposed rotation axis.

[0010] In some embodiments, the storage platform includes a storage platform body and a connecting plate, the storage platform body is used to place the covering agent, and the connecting plate is rotatably connected to the storage platform body around a second rotating shaft arranged vertically;

[0011] The transmission frame is rotatably connected to the connection plate around a first horizontally arranged rotation axis.

[0012] In some embodiments, the connecting plate is also movably connected to the storage table body along the axial direction of the second rotation axis.

[0013] In some embodiments, the second rotating shaft is disposed on the storage table body, a connecting hole is formed on the connecting plate, and the second rotating shaft passes through the connecting hole;

[0014] The covering agent conveying device further includes a positioning nut, which is threadedly connected to the second rotating shaft and is located below the connecting plate and in contact with the connecting plate.

[0015] In some embodiments, two transmission racks are provided, and the two transmission racks are rotatably connected around a third horizontally arranged rotation axis.

[0016] In some embodiments, the transmission frame includes a frame body and a plurality of transmission rollers rotatably connected to the frame body.

[0017] In some embodiments, along a direction perpendicular to the transmission direction of the transmission rack, both sides of the rack body are provided with material blocking plates extending along the transmission direction.

[0018] In some embodiments, the covering agent conveying device further comprises a roller, and the roller is mounted on the storage table.

[0019] In some embodiments, the storage table has a storage cavity, and the covering agent is placed in the storage cavity.

[0020] The utility model has at least the following beneficial effects:

[0021] The utility model comprises a storage table and a transmission frame, wherein the storage table is used for placing a covering agent; the transmission frame is used for transmitting the covering agent, one side of the transmission frame is connected to the storage table, and the height of the side connected to the storage table is higher than the height of the other side, so that the transmission frame is arranged in an inclined manner, thereby enabling the covering agent on the transmission frame to be transmitted from a side close to the storage table to a side far from the storage table under the action of gravity.

[0022] In this way, when it is necessary to add covering agent to the tundish, the transfer rack is placed on the tundish at the side away from the storage table. The operator stands next to or on the storage table and places the covering agent on the storage table on the transfer rack. The covering agent will slide along the transfer rack into the tundish under the action of gravity, which reduces the operator's work intensity and helps to improve the efficiency of dosing.

[0023] In this way, the operator can add materials away from the ladle, which to a certain extent avoids the molten steel from splashing onto the operator. The operator is less affected by the molten steel temperature and the dust generated by the covering agent, which in turn reduces the risk of adding covering agents to a certain extent and helps to ensure the health of the operator.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0039] In the continuous casting process, in order to ensure the purity of molten steel and prevent secondary oxidation, the molten steel needs to be fully protected and the molten steel inside the tundish needs to be protected by a covering agent. Continuous casting is a continuous process, and the covering agent added to the tundish will be continuously melted and consumed, so the amount of covering agent put into the tundish is huge and continuous.

[0040] In the related art, the most common method used is manual bagging, that is, a person stands near the tundish, holds a bag of covering agent, and puts the bag of covering agent into the tundish. This method requires experienced operators and has high requirements for operators. In the initial pouring process, the demand for covering agent is large, and at least three operators are required to feed the material at the same time.

[0041] The manual bag feeding method is not only labor-intensive and inefficient, but also the operator is close to the tundish during feeding. The operator is very likely to be scalded by the splashing molten steel, causing safety accidents. The operator also needs to endure the high temperature and the large amount of dust generated by the addition of the covering agent, which will cause serious harm to the operator's health in the long run.

[0042] Therefore, in the related art, there is a technical problem of relatively high risk when adding covering agent. The embodiment of the present application provides a covering agent conveying device, which can at least solve the technical problem of relatively high risk when adding covering agent to a certain extent.

[0043] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0044] The embodiment of the present application provides a covering agent conveying device 100. The covering agent conveying device 100 provided in the embodiment of the present application can reduce the intensity of the operator's work and reduce the danger when adding the covering agent to a certain extent.

[0045] like Figure 1 As shown, the covering agent conveying device 100 includes a storage table 110 and a transfer rack 120 .

[0046] The storage table 110 is used for placing the covering agent. When in use, the covering agent is placed on the storage table 110.

[0047] The transfer rack 120 is used to transfer the covering agent. One side of the transfer rack 120 is connected to the storage table 110. The height of the side connected to the storage table 110 is higher than the height of the other side, so that the covering agent placed on the transfer rack 120 can be transferred from the side close to the storage table 110 to the side far away from the storage table 110.

[0048] When using, Figure 7As shown, the other side of the transfer rack 120 is placed on the intermediate bag 200, and the operator stands on the storage table 110 or next to the storage table 110 to place the covering agent on the transfer rack 120. Since the height of the side where the transfer rack 120 is connected to the storage table 110 is higher than the height of the other side, the covering agent will slide along the transfer rack 120 under the action of gravity until it falls from the transfer rack 120 and is transferred to the intermediate bag 200.

[0049] With this design, on the one hand, the operator only needs to place the covering agent from the storage table 110 onto the transmission rack 120, and the covering agent is transmitted along the transmission rack 120. The operator does not need to move the covering agent over a long distance, and the operator does not need to throw or drop the covering agent. Therefore, the operator's labor intensity is reduced to a certain extent, and it helps to improve the efficiency of covering agent addition.

[0050] On the other hand, due to the transmission rack 120, the storage table 110 can be placed away from the tundish 200. In this way, the operator can add material away from the tundish 200, which reduces the possibility of molten steel splashing on the operator to a certain extent. At the same time, it helps the operator to stay away from the tundish 200. Therefore, the operator is less affected by the molten steel temperature and the dust of the covering agent. Therefore, the risk of adding the covering agent is reduced to a certain extent, which helps to ensure the health of the operator.

[0051] In some embodiments, Figure 2 As shown, the transmission frame 120 is rotatably connected to the storage table 110 around a horizontally arranged first rotation axis 130. In other words, the side of the transmission frame 120 connected to the storage table 110 is rotatably connected. With this design, the transmission frame 120 can rotate around the first rotation axis 130, and the height of the side of the transmission frame 120 away from the connecting plate 112 (i.e., the side placed on the tundish 200) can be adjusted. The heights of different places on the tundish 200 are inconsistent, so that the transmission frame 120 can be adapted to different parts of the tundish 200, and the covering agent can be successfully transferred.

[0052] It should be noted that the horizontal setting does not mean that the first rotating shaft 130 is strictly parallel to the horizontal plane. Due to errors in manufacturing, installation, etc., there may be a certain angle between the first rotating shaft 130 and the horizontal plane, such as 1°, 2°, 3°, 4°, etc. Therefore, even if there is a certain angle between the first rotating shaft 130 and the horizontal plane, the height of the side of the transmission frame 120 away from the connecting plate 112 can be adjusted and the function of transmitting goods can be realized, which also belongs to the "horizontal setting" mentioned in this application.

[0053] In some embodiments, Figure 2As shown, the storage platform 110 includes a storage platform body 111 and a connecting plate 112. The storage platform body 111 is used to place the covering agent. The connecting plate 112 is rotatably connected to the storage platform body 111 around a second rotating shaft 140 arranged vertically. The transmission frame 120 is rotatably connected to the connecting plate 112 around a first rotating shaft 130 arranged horizontally. With this design, the transmission frame 120 is rotatably connected to the connecting plate 112, and the connecting plate 112 is rotatably connected to the storage platform body 111.

[0054] When adding the covering agent, it is not necessary to add it to one place in the tundish 200, but it is necessary to add it evenly to all places in the tundish 200 to ensure the protection effect. Since the storage table 110 is placed with the covering agent, the weight of the covering agent is relatively heavy, so it is inconvenient to move the storage table 110. After such a design, if Figure 7 As shown, the transfer frame 120 can be horizontally rotated around the second rotating axis 140 without moving the storage table 110, so that the position of the transfer frame 120 on the intermediate ladle 200 away from the storage table 110 is changed, so that the covering agent can be added to different areas of the intermediate ladle 200 to ensure the protective effect of the covering agent and improve the efficiency of adding the covering agent.

[0055] Similarly, it should be noted that the vertical arrangement does not mean that the second rotation axis 140 is strictly perpendicular to the horizontal plane. Due to errors in manufacturing, installation, etc., the second rotation axis 140 may be at an acute or obtuse angle to the horizontal plane, such as 89°, 95°, 85°, etc. Therefore, even if the second rotation axis 140 is at an acute or obtuse angle to the horizontal plane, the transfer rack 120 can be rotated, and the position of the transfer rack 120 on the tundish 200 away from the storage table 110 can be changed, which also belongs to the "vertical arrangement" mentioned in this application.

[0056] In some embodiments, the connecting plate 112 is also movably connected to the storage platform body 111 along the axial direction of the second rotating shaft 140. That is, the connecting plate 112 is not only rotatably connected to the storage platform body 111 along the second rotating shaft 140, but also movably connected along the axial direction of the second rotating shaft 140. The connecting plate 112 can rotate around the second rotating shaft 140 and can also move along the axial direction of the second rotating shaft 140 to adjust the height of the connecting plate 112, thereby adjusting the height of the end of the transmission frame 120 connected to the connecting plate 112, thereby adjusting the inclination of the transmission frame 120.

[0057] There are various ways for the connecting plate 112 to be movably connected to the second rotating shaft 140 , which are not limited in the present application.

[0058] In some embodiments, Figure 4As shown, the second rotating shaft 140 is arranged on the storage platform body 111, and its upper end is fixedly connected to the storage platform body 111. A connecting hole 112a is opened on the connecting plate 112, and the second rotating shaft 140 is passed through the connecting hole 112a, so that the connecting plate 112 is rotatably connected to the second rotating shaft 140. The covering agent conveying device 100 also includes a positioning nut 150, which is threadedly connected to the second rotating shaft 140, and is located below the connecting plate 112 and contacts the connecting plate 112. With this design, by screwing the positioning nut 150, the position of the positioning nut 150 on the second rotating shaft 140 can be adjusted, and then the position of the connecting plate 112 on the second rotating shaft 140 can be adjusted, so that the height of the connecting plate 112 can be adjusted.

[0059] In some embodiments, Figure 5 As shown, the second rotating shaft 140 is arranged on the storage platform body 111, and its upper end is fixedly connected to the storage platform body 111. A connecting hole 112a is provided on the connecting plate 112, and the second rotating shaft 140 is passed through the connecting hole 112a, so that the connecting plate 112 is rotatably connected with the second rotating shaft 140. The covering agent conveying device 100 also includes a latch 190. The second rotating shaft 140 is provided with latch holes 140a of different heights. The latch 190 is inserted into the latch hole 140a and is located below the connecting plate 112 and contacts the connecting plate 112. With this design, the latch 190 cooperates with different latch holes 140a, so that the position of the latch 190 on the second rotating shaft 140 can be adjusted, and then the position of the connecting plate 112 on the second rotating shaft 140 can be adjusted, so that the height of the connecting plate 112 can be adjusted.

[0060] The number of transmission racks 120 provided is not limited in the present application, and it can be one or multiple transmission racks 120 connected in sequence.

[0061] In some embodiments, Figure 3 and Figure 6 As shown, two transmission racks 120 are provided, and the two transmission racks 120 are rotatably connected around a third rotating shaft 160 arranged horizontally. With this design, the transmission rack 120 near the storage table 110 of the two transmission racks 120 is connected to the transmission rack 120. When the covering agent conveying device 100 is not used or moved, the transmission rack 120 far from the storage table 110 can be rotated and placed on the transmission rack 120 near the storage table 110, as shown in FIG. Figure 7 As shown, the footprint of the covering agent conveying device 100 is reduced to facilitate movement and storage.

[0062] It should be noted that, similar to the first rotation axis 130, the third rotation axis 160 is horizontally arranged, which does not mean that the third rotation axis 160 is strictly parallel to the horizontal plane. Due to errors in processing, manufacturing, installation, etc., there may be a certain angle between the third rotation axis 160 and the horizontal plane, such as 1°, 2°, 3°, 4°, etc. Therefore, even if there is a certain angle between the third rotation axis 160 and the horizontal plane, the transmission rack 120 far from the storage table 110 can be rotated and placed on the transmission rack 120 close to the storage table 110, which also belongs to the "horizontal arrangement" mentioned in this application.

[0063] In some embodiments, Figure 1 As shown, the transmission frame 120 includes a frame body 121 and a plurality of transmission rollers 122 rotatably connected to the frame body 121. With such a design, under the action of the transmission rollers 122, the rolling friction between the covering agent and the transmission frame 120 helps to reduce the friction between the transmission frame 120 and the covering agent, making it easier for the covering agent to slide along the transmission frame 120.

[0064] In some embodiments, Figure 8 As shown, along the direction perpendicular to the transmission direction of the transmission frame 120, both sides of the frame body 121 are provided with a material blocking plate 170 extending along the transmission direction. Figure 8 As shown, baffle plates 170 are respectively provided on both sides of the width direction of the frame 121. The baffle plates 170 are provided to limit the covering agent on the transmission roller 122 to prevent the covering agent from falling from both sides of the width direction of the frame 121 during transmission, so as to ensure that the covering agent can slide smoothly into the intermediate bag 200.

[0065] In some embodiments, in order to facilitate the movement of the covering agent conveying device 100, the covering agent conveying device 100 further includes a roller 180, and the roller 180 is installed on the storage platform 110. Figure 8 As shown, the storage platform 110 is in a rectangular shape as a whole, and four rollers 180 are provided, and the four rollers 180 are respectively installed at the four corners of the bottom of the storage platform 110. In some embodiments, brake pads are provided on the rollers 180 to prevent the covering agent conveying device 100 from sliding by itself.

[0066] In some embodiments, Figure 8 As shown, the storage platform 110 has a storage cavity 111 a, and the covering agent is placed in the storage cavity 111 a. In the embodiment where the storage platform 110 includes a connecting plate 112 and a storage platform body 111, the storage cavity 111 a is disposed on the storage platform body 111.

[0067] like Figure 8 As shown, in some embodiments, the top of the storage cavity 111a is open to facilitate the placement or removal of the covering agent.

[0068] The working principle of the covering agent conveying device 100 of the present application is introduced as follows:

[0069] First, the operator hoists the covering agent onto the storage platform 110, then opens the folded transfer rack 120, places the side of the transfer rack 120 away from the storage platform 110 onto the tundish 200, aligns the cover hole 200a on the tundish 200, and supports the rotating connection between the two transfer racks 120 to prevent the transfer rack 120 from collapsing during the transfer process. Next, adjust the positioning nut 150 so that the height of the side where the transfer rack 120 is connected to the storage platform 110 is higher than the height of the side where the tundish 200 is placed. Next, the operator stands next to the storage platform 110 and places the covering agent on the storage platform 110 onto the transfer rack 120. Under the action of gravity, the covering agent slides along the transfer rack 120 and enters the tundish through the cover hole 200a on the tundish 200. When it is necessary to add covering agent to other parts of the tundish 200 , the transfer frame 120 is rotated around the second rotation axis 140 so that the side of the transfer frame 120 placed on the tundish 200 is aligned with other cover holes 200 a on the tundish 200 .

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
