Description

Technical Field

[0001] This application belongs to the technical field of metallurgy, and particularly relates to a protective device. Background Technology

[0002] Sintered ore is an important raw material for blast furnace ironmaking. Sintered ore has a Rockwell hardness of 57-63, indicating a high Rockwell hardness.

[0003] Sintering machines typically have supporting beams at the material feeding position, and the ore bin usually has steps inside. In exchange-cooling sintering machines, a ore bin is designed below the single-roll crusher, and the height difference between the ore bin and the annular cooler exceeds 10 meters. To mitigate this, the ore bin is usually designed with a buffer triangular beam to reduce the direct impact of the material feeding. Supporting beams, steps, triangular beams, and other components are all subject to erosion from the sintered ore.

[0004] Due to the high hardness of sintered ore, the components such as supporting beams, steps, and triangular beams that are affected by the sintered ore wear out quickly. As a result, companies spend a lot of manpower and financial resources every year on repairs or replacements. Utility Model Content

[0005] This application aims to at least partially solve the technical problem of rapid wear rates in components such as support beams, steps, and triangular beams subjected to sinter erosion. To this end, this application provides a protective device.

[0006] This application provides a protective device for protecting a protected component, comprising:

[0007] First protective plate;

[0008] A first connecting component is installed on the first protective plate and is used to connect with the protected component;

[0009] The second protective plate is connected to the first protective plate and is set at an angle to the first protective plate. The first protective plate and the second protective plate together form an accumulation groove.

[0010] In some embodiments, along the X direction, both ends of the second protective plate extend beyond the first protective plate or are flush with both ends of the first protective plate.

[0011] In some embodiments, the first protective plate is perpendicular to the Z-direction, and the second protective plate is perpendicular to the Y-direction.

[0012] In some embodiments, along the Z-direction, the first protective plate is connected to the middle of the second protective plate.

[0013] In some embodiments, along the Z-direction, the first protective plate includes a first side and a second side disposed opposite to each other, the first side and the first protective plate forming the accumulation groove;

[0014] The protective device further includes a second connecting component, which is installed on the second side and used to connect with the protected component.

[0015] In some embodiments, the second protective plate is provided with a second recess and a second clearance through hole, the second clearance through hole being formed on the bottom wall of the second recess;

[0016] The second connection component includes:

[0017] The second bolt has its second head located in the second recess, and at least a portion of the second thread of the second bolt is located in the second clearance through hole.

[0018] The second nut is threaded onto the second screw.

[0019] In some embodiments, the first protective plate is provided with a first clearance through hole;

[0020] The first connection component includes:

[0021] The first bolt, wherein at least a portion of the first thread of the first bolt is located within the first clearance through hole;

[0022] The first nut is threaded onto the first screw.

[0023] In some embodiments, the protective device further includes a reinforcing plate connected to the first protective plate and the second protective plate.

[0024] In some embodiments, a plurality of reinforcing plates are provided, and the plurality of reinforcing plates are spaced apart along the X direction.

[0025] In some embodiments, the reinforcing plate is disposed within the accumulation groove.

[0026] This utility model has at least the following beneficial effects:

[0027] After the protective device is fixed to the protected part through the first connecting component, the first protective plate is located above the protected part, blocking at least a portion of the protected part. Sintered ore falls from above onto the first protective plate, and the first protective plate is washed away by the sintered ore instead of the protected part, reducing the wear rate of the protected part. At least a portion of the second protective plate is located above the second protective plate, and the two protective plates together form an accumulation trough. When the sintered ore falls from above, the second protective plate can intercept some of the sintered ore, causing some of the sintered ore to accumulate in the accumulation trough, that is, above the first protective plate. In this way, the newly falling sintered ore washes away the sintered ore accumulated in the accumulation trough, forming a "material-to-material" form. The sintered ore accumulated in the accumulation trough can effectively protect the first protective plate, the second protective plate, and the first connecting component, so that the first protective plate, the second protective plate, and the first connecting component are protected from wear by the sintered ore or the wear rate is reduced. The service life of the protective device and the protected part is longer, which helps to reduce the frequency of maintenance, reduce the labor intensity of employees, improve the stability of production, and bring good economic benefits to the enterprise.

[0041] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] In related technologies, components such as support beams, steps, and triangular beams subjected to sinter erosion suffer from rapid wear rates. This application provides a protective device that can at least partially address the problem of rapid wear rates in support beams, steps, and triangular beams subjected to sinter erosion.

[0043] For ease of description below, we define the X, Y, and Z directions, which are perpendicular to each other.

[0044] This application is described below with reference to the accompanying drawings and specific embodiments:

[0045] like Figures 1 to 5 As shown, the protective device 100 is used to protect the protected component and includes: a first protective plate 110, a first connecting assembly 120, and a second protective plate 130. The first connecting assembly 120 is installed on the first protective plate 110 and is used to connect with the protected component. The second protective plate 130 is connected to the first protective plate 110 and is set at an angle to the first protective plate 110. The first protective plate 110 and the second protective plate 130 together form an accumulation groove 100a.

[0046] The protected components can be components that are subject to erosion by sintered ore, such as the supporting beam 300, the step 200, and the triangular beam 400.

[0047] When the protective device 100 is in use, the first connecting component 120 is connected to both the first protective plate 110 and the protected part, and the first connecting component 120 fixes the first protective plate 110 to the protected part. The second protective plate 130 is fixedly connected to the first protective plate 110, and its angle setting can be a right angle, an acute angle, or an obtuse angle.

[0048] After the protective device 100 is fixed to the protected part via the first connecting assembly 120, the first protective plate 110 is located above the protected part, blocking at least a portion of the protected part. When sintered ore 500 falls from above, it lands on the first protective plate 110, which is then washed away by the sintered ore 500, reducing the wear rate of the protected part. At least a portion of the second protective plate 130 is located above the second protective plate 130, forming an accumulation tank 100a. When the sintered ore 500 falls from above, the second protective plate 130 can intercept some of the sintered ore 500, causing some of the sintered ore 500 to accumulate in the accumulation tank 100a, i.e., to accumulate... The sintered ore 500 accumulates above the first protective plate 110. In this way, the newly falling sintered ore 500 washes over the sintered ore 500 accumulated in the accumulation tank 100a, forming a "material-to-material" process. The sintered ore 500 accumulated in the accumulation tank 100a can effectively protect the first protective plate 110, the second protective plate 130, and the first connecting component 120, preventing them from being worn by the sintered ore 500 or reducing the wear rate. This extends the service life of the protective device 100 and the protected components, helps reduce the frequency of maintenance, reduces the labor intensity of employees, improves the stability of production, and brings better economic benefits to the enterprise.

[0049] like Figure 6 As shown, Figure 6 A schematic diagram is shown showing the protective device 100 installed on the step 200 when the protected object is the step 200. It can be understood that when the protected object is the step 200, the first connecting assembly 120 and the second connecting assembly 140 (described later) can be detachably connected to the step 200 so that the protective device 100 can be removed from the step 200 to facilitate the movement of workers on the step 200 during maintenance work.

[0050] like Figure 7 As shown, Figure 7 A schematic diagram is shown of the protective device 100 installed on the support beam 300 when the protected component is the support beam 300.

[0051] like Figure 8 As shown, Figure 8 A schematic diagram is shown of the protective device 100 installed on the triangular beam 400 when the protected component is the triangular beam 400.

[0052] The first protective plate 110, the second protective plate 130, the first connecting component 120, and the second connecting component 140 (described later) can be made of high-chromium alloy or similar materials. High-chromium alloy has good wear resistance, which ensures the service life of the protective device 100.

[0053] The connection between the first protective plate 110 and the second protective plate 130 can be varied, such as welding, snap-fitting, bolting, etc., and is not limited in this application.

[0054] In some embodiments, the first protective plate 110 and the second protective plate 130 are welded together.

[0055] In some embodiments, the first protective plate 110 and the second protective plate 130 are integrally formed, which can be done by 3D printing, machining, casting or other methods.

[0056] The shape and size of the first protective plate 110 and the second protective plate 130 are varied and are not limited in this application. The shape can be rectangular, square, oval, etc. The size is related to the size of the protected part and can be set according to the user's needs.

[0057] In some embodiments, both the first protective plate 110 and the second protective plate 130 are rectangular, and each of the sharp corners of the first protective plate 110 and the second protective plate 130 is rounded to avoid scratching the inner wall of the silo and storage bin, or scratching the operators.

[0058] The second protective plate 130 intercepts the sintered ore 500. Without the second protective plate 130, the sintered ore 500 cannot be intercepted, resulting in less sintered ore 500 accumulating on the first protective plate 110 or no sintered ore 500 accumulating on the first protective plate 110 at all points along the X direction. If the second protective plate 130 cannot cover all points of the first protective plate 110 along the X direction, it is difficult for sintered ore 500 to accumulate above the areas not covered by the second protective plate 130, and these areas are easily subjected to severe wear and tear from continuous impacts by the falling sintered ore 500. Therefore, in some embodiments, along the X direction, both ends of the second protective plate 130 extend beyond the first protective plate 110 or are flush with both ends of the first protective plate 110. This ensures that the second protective plate 130 covers all points of the first protective plate 110, allowing a certain amount of sintered ore 500 to accumulate above each point of the first protective plate 110 along the X direction, thus guaranteeing the service life of the first protective plate 110.

[0059] like Figure 2 As shown, in some embodiments, along the X direction, the two ends of the first protective plate 110 are flush with the two ends of the second protective plate 130.

[0060] like Figure 1 As shown, in some embodiments, the first protective plate 110 is perpendicular to the Z-direction, and the second protective plate 130 is perpendicular to the Y-direction. That is, the first protective plate 110 and the second protective plate 130 are arranged perpendicularly, which helps to accumulate more sintered ore 500 in the accumulation tank 100a.

[0061] In some embodiments, after the protective device 100 is fixed to the protected member, the Z-direction is parallel to the height direction.

[0062] like Figure 1 As shown, in some embodiments, along the Z-direction, the first protective plate 110 is connected to the middle of the second protective plate 130.

[0063] With this design, the first protective plate 110 and the second protective plate 130 are in a "T" shape.

[0064] Along the Z-direction, the first protective plate 110 includes a first side 131 and a second side 132 disposed opposite to each other. The first side 131 of the second protective plate 130 is located above the first protective plate 110, and the second side 132 of the second protective plate 130 is located below the first protective plate 110. The first side 131 and the first protective plate 110 together form an accumulation groove 100a. With the second side 132 located below the first protective plate 110, this design allows the second side 132 to shield at least a portion of the protected component along the Y-direction, thereby providing protection to a portion of the protected component and extending its service life. (See reference...) Figure 6 , Figure 7 and Figure 8 As shown.

[0065] In some embodiments, the protective device 100 further includes a second connecting component 140, which is mounted on the second side 132 of the second protective plate 130 and is used to connect with the protected component.

[0066] The second connecting component 140 is connected to both the second protective plate 130 and the protected component. With this design, the protective device 100 is also connected to the protected component through the second connecting component 140, ensuring the stability of the protective device 100 after installation.

[0067] The second connecting component 140 may include only one component, such as only a bolt, screw, or wire. The second connecting component 140 may also include multiple components, such as bolts and nuts. Its structure is diverse and is not limited in this application.

[0068] like Figure 4 As shown, in some embodiments, the second protective plate 130 has a second recess 130a and a second clearance through hole 130b, the second clearance through hole 130b being formed in the bottom wall of the second recess 130a. The second connecting assembly 140 includes a second bolt 141 and a second nut 142. The second head 1411 of the second bolt 141 is located in the second recess 130a, and at least a portion of the second thread 1412 of the second bolt 141 is located in the second clearance through hole 130b. The second nut 142 is threadedly connected to the second thread 1412.

[0069] The second settling tank 130a is used to accommodate the second head 1411, so that the second head 1411 does not protrude from the surface of the second protective plate 130. The fact that the second head 1411 does not protrude from the surface of the second protective plate 130 can reduce the probability of the second head 1411 being washed by the sinter 500, which helps to extend the service life of the second protective device 100.

[0070] The second clearance through hole 130b is used to avoid the second screw 1412, so that the end of the second screw 1412 away from the second head 1411 can pass through the second protective plate 130. The second nut 142 is threadedly connected to the side of the second screw 1412 away from the second head 1411.

[0071] It should be noted that the protected component has a through hole for avoiding the second screw 1412. When the protective device 100 is installed, the second nut 142 is first unscrewed from the second screw 1412, then the second screw 1412 passes through the through hole of the protected component, and then the second nut 142 is screwed onto the second screw 1412. In this way, at least a part of the protected component and at least a part of the second protective component are located between the second nut 142 and the second head 1411. The second nut 142 and the second head 1411 together clamp the protected component and the second protective component, thereby fixing the protected component and the protective device 100.

[0072] In some embodiments, three second connecting components 140 are spaced apart along the X direction on the second protective plate 130.

[0073] The first connecting component 120 may include only one component, such as only a bolt, screw, or wire. The first connecting component 120 may also include multiple components, such as bolts and nuts. Its structure is diverse and is not limited in this application.

[0074] like Figure 4 As shown, in some embodiments, the first protective plate 110 has a first clearance through hole 110a; the first connecting assembly 120 includes a first bolt 121 and a first nut 122. At least a portion of the first thread 1212 of the first bolt 121 is located within the first clearance through hole 110a. The first nut 122 is threadedly connected to the first thread 1212.

[0075] The first clearance through hole 110a is used to avoid the first screw 1212, so that the end of the first screw 1212 away from the first head 1211 can pass through the first protective plate 110. The first nut 122 is threadedly connected to the side of the first screw 1212 away from the first head 1211.

[0076] It should be noted that the protected component is also provided with a through hole for avoiding the first screw 1212. When the protective device 100 is installed, the first nut 122 is first unscrewed from the first screw 1212, then the first screw 1212 passes through the through hole of the protected component, and then the first nut 122 is screwed onto the first screw 1212. In this way, at least a part of the protected component and at least a part of the first protective plate 110 are located between the first nut 122 and the first head 1211. The first nut 122 and the first head 1211 together clamp the protected component and the first protective component, so that the protected component and the protective device 100 are fixed.

[0077] In some embodiments, along the X direction, two first connecting components 120 are spaced apart on the first protective plate 110.

[0078] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the protective device 100 further includes a reinforcing plate 150, which is connected to the first protective plate 110 and the second protective plate 130.

[0079] The reinforcing plate 150 is connected to both the first protective plate 110 and the second protective plate 130, which improves the connection strength between the first protective plate 110 and the second protective plate 130 and improves the structural strength of the protective device 100.

[0080] The connection methods between the reinforcing plate 150 and the first protective plate 110, as well as the connection methods between the reinforcing plate 150 and the second protective plate 130, are varied, such as bolt connection, welding, snap-fit, etc., and are not limited in this application.

[0081] In some embodiments, the reinforcing plate 150 is welded to the first protective plate 110, and the reinforcing plate 150 is also welded to the second protective plate 130.

[0082] like Figure 3 As shown, in some embodiments, multiple reinforcing plates 150 are provided, and the multiple reinforcing plates 150 are spaced apart along the X direction. The provision of multiple reinforcing plates 150 further improves the connection strength between the first protective plate 110 and the second protective plate 130, and improves the structural strength of the protective device 100.

[0083] In some embodiments, the reinforcing plate 150 is disposed in the accumulation tank 100a, such that the sinter 500 accumulated in the accumulation tank 100a can cover the reinforcing plate 150, thereby providing protection for the reinforcing plate 150, reducing the wear rate of the reinforcing plate 150, and helping to improve the service life of the reinforcing plate 150.

[0084] In some embodiments, three reinforcing plates 150 are provided.
