Description

Technical Field

[0001] This utility model relates to the field of sintering equipment technology, and in particular to a sealing device between the side panels of a sintering machine trolley. Background Technology

[0002] Air leakage in sintering machines has always been a major challenge in sintering production. Air leakage not only increases the energy consumption of the main exhaust fan and reduces the yield and quality of sintered ore, but also negatively impacts the recovery and utilization of waste heat from sintering flue gas. Furthermore, it increases the oxygen content in the system, making it impossible to meet the national ultra-low emission standards. The sintering machine trolleys operate under high temperatures for extended periods, causing the trolley sidewalls to warp and deform. Combined with limitations in manufacturing and installation, gaps exist between the sidewalls of adjacent trolleys, leading to air leakage between them. This results in a high air leakage rate in the sintering machine, high energy consumption in the sintering system, and low sintered ore quality. Because the trolleys need to move and rotate when moving from the loaded to the empty track, the angle and relative position between adjacent trolleys change. During this process, the sealing mechanisms in existing technologies are prone to wear, wrinkling, or malfunction, leading to seal failure between the sidewalls of the trolleys and adjacent trolleys, thus affecting the sintering process.

[0003] Therefore, there is an urgent need to design a technical solution that can prevent damage caused by the rotation of the trolley, which could lead to seal failure. Utility Model Content

[0004] The purpose of this invention is to provide a sealing device between the side panels of a sintering machine trolley to solve the problems existing in the prior art, thereby avoiding damage caused by the rotation of the trolley and achieving a good sealing effect.

[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a sealing device between the side panels of a sintering machine trolley, comprising: The mounting base is fixed to the side panel of the trolley, and a mounting mechanism is provided on the outer side of one end of the base.

[0007] Preferably, the trolley sideboard includes an upper sideboard and a lower sideboard of the same length. The bottom of the upper sideboard is provided with a first flange extending outward, and the top of the lower sideboard is provided with a second flange extending outward. The first flange and the second flange are fixedly connected, and the mounting base is fixedly connected to the upper side of the first flange or the lower side of the second flange.

[0008] Preferably, an outer edge plate is provided on the outer side of one end of the mounting base plate, and a strip hole is formed on the outer edge plate. The outer edge plate and the strip hole form the mounting mechanism, and the frame is vertically fixedly connected to the strip hole of the outer edge plate.

[0009] Preferably, the frame includes an upper frame and a lower frame, the bottom of the upper frame is fixed to the upper surface of the mounting mechanism by an upper frame base, and the top of the lower frame is fixed to the lower surface of the mounting mechanism by a lower frame base.

[0010] Preferably, the sealing plate mechanism includes a sealing plate bracket and a flexible sealing plate; the sealing plate bracket is fixed on both the upper and lower frame, the sealing plate bracket is horizontally arranged and has elasticity; the flexible sealing plate is fixedly connected to the end of the sealing plate bracket away from the frame, and the flexible sealing plate can adsorb and adhere to the gap between the two trolley side panels under the negative pressure inside the trolley to achieve sealing of the gap.

[0015] The present invention achieves the following technical advantages over the prior art: During operation, the airflow generated by the bellows creates negative pressure inside the sintering machine. This invention features a mounting base plate on the trolley sidewall outside the sintering machine. A sealing plate mechanism is installed on the mounting base plate near the gap between two adjacent trolleys via a frame. Under the negative pressure inside the trolley, the sealing plate mechanism is drawn into and adheres to the gap, thus sealing it. When the trolley rotates from the loaded lane to the empty lane, or vice versa, the sealing plate mechanism is not directly fixed to the sintering machine trolley.

Simultaneously, when entering the loaded lane, under negative pressure, it can automatically reset elastically and tightly adhere to the gap, achieving safety and stability without causing compression deformation or wrinkling.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a sealing device between the side panels of a sintering machine trolley to solve the problems existing in the prior art, thereby avoiding damage caused by the rotation of the trolley and achieving a good sealing effect.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Because the trolleys need to move and rotate during their movement from the loaded track to the empty track, or vice versa, the angle and relative position between adjacent trolleys change. In this process, the sealing mechanism in existing technologies is fixedly connected to the outside of the trolley, making it prone to wear, wrinkles, or malfunctions. This leads to seal failure between the trolley side panels and adjacent trolley side panels, thus affecting the sintering process. To solve this problem, this utility model provides a sealing device between the trolley side panels of a sintering machine. (Reference) Figure 1 , Figure 2As shown, the sintering machine includes a mounting base plate 2, a frame, and a flexible sealing plate mechanism. The mounting base plate 2 is fixed to the trolley sideboard, and a mounting mechanism is provided on the outer side of one end of the mounting base plate 2. The mounting mechanism is located near the gap between two adjacent trolley sideboards. The frame is fixed to the mounting mechanism of the mounting base plate 2. The sealing plate mechanism is connected to the frame and is located on the outer side of the gap between two adjacent trolley sideboards. Under the negative pressure inside the trolley, it can adsorb and adhere to the gap between the two trolley sideboards to seal the gap. During the operation of the sintering machine, the suction force generated by the main induced draft fan and the air force generated by the air box will create a negative pressure inside the sintering machine. The air box and the sintering machine are existing technologies and will not be described in detail. This invention features a mounting base plate 2 installed on the outer side panel of the sintering machine's trolley. A sealing plate mechanism is mounted on the mounting base plate 2 near the gap between two adjacent trolleys via a frame. The air box creates a pressure difference between the inside and outside of the trolley, with the internal pressure being lower than the external pressure. Under this negative pressure, the sealing plate mechanism is drawn to the gap, effectively sealing it. When the trolley rotates from the loaded lane to the empty lane, or vice versa, the sealing plate mechanism is not directly fixed to the sintering machine trolley 1. Therefore, during rotation, as the angle between adjacent trolleys changes, the negative pressure decreases. Under low or no negative pressure, the sealing plate mechanism automatically detaches from the gap between the trolleys, preventing it from scraping against the curve. Simultaneously, when entering the loaded lane, under negative pressure, it automatically resets elastically and tightly seals the gap, achieving safety and stability without causing compression deformation or wrinkling.

[0023] Example 1 refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the trolley sideboard includes an upper sideboard 101 and a lower sideboard 102 of the same length. The bottom of the upper sideboard 101 is provided with a first flange 9 extending outward, and the top of the lower sideboard 102 is provided with a second flange 10 extending outward. The first flange 9 and the second flange 10 are fixedly connected by bolts to form the trolley sideboard. There is a certain vertical gap between the sidewalls of the trolley sideboards of two adjacent trolleys. In order to achieve sealing at this gap, in one embodiment, a mounting base plate 2 is fixedly clamped between the first flange 9 and the second flange 10. The mounting base plate 2 has through holes at the same positions as the first flange 9 and the second flange 10 for bolts connecting the first flange 9 and the second flange 10 to pass through. The length of the mounting base plate 2 is the same as the length of the upper sideboard 101. Since the mounting base plate 2 is the same length as the trolley sideboard, it can fill the space between the first flange 9 and the second flange 10, thereby ensuring the sealing between the first flange 9 and the second flange 10.

[0024] In one embodiment, an outer edge plate 201 is integrally formed on the outer side of one end of the mounting substrate 2. A strip hole 202 is provided on the outer edge plate 201. The outer edge plate 201 and the strip hole 202 form a mounting mechanism. The frame includes an upper frame 3 and a lower frame 4. The bottom of the upper frame 3 is fixed to the upper surface of the outer edge plate 201 by an upper frame base 5. The top of the lower frame 4 is fixed to the lower surface of the outer edge plate 201 by a lower frame base 6. The upper frame base 5 and the lower frame base 6 are arranged symmetrically on top of each other and are fixed to the strip hole 202 of the outer edge plate 201 by bolts. By adjusting the position of the bolts at the strip hole 202, the position of the frame can be adjusted so that the sealing plate mechanism on the frame corresponds more closely to the position of the gap to be sealed.

[0025] In one embodiment, the sealing plate mechanism includes a sealing plate bracket 7 and a flexible sealing plate 8. At least one sealing plate bracket 7 is fixed on both the upper frame 3 and the lower frame 4. The sealing plate bracket 7 is horizontally arranged and elastic, and can be close to or away from the gap. The flexible sealing plate 8 is fixedly connected to the end of the sealing plate bracket 7 away from the frame. The flexible sealing plate 8 can be adsorbed and attached to the gap between the two trolley side panels under the negative pressure inside the trolley to seal the gap. The sealing plate bracket 7 has a certain elasticity and can expand outward and automatically reset. In one embodiment, the sealing plate bracket 7 is made of spring steel plate, which has its own elasticity, so that the trolleys can automatically separate at the bend. At the same time, it can automatically disengage from the gap between the trolleys when the negative pressure is low or there is no negative pressure, so that the flexible sealing plate 8 entering the bend can separate and not scrape at the bend. At the same time, when entering the heavy lane, under negative pressure, it can automatically reset through elasticity and make the flexible sealing plate 8 tightly fit the gap, so as to achieve the purpose of safety and stability. The flexible sealing plate 8 can be made of rubber or other flexible materials such as metal or plastic.

[0026] In one embodiment, the sealing plate bracket 7 has an outwardly extending smooth bend 701 at the end away from the frame. This smooth bend 701 allows for a smooth transition when the trolley deviates from its course, preventing scratches and damage. Under negative pressure, it also ensures a tight seal, completely sealing the gap between the trolleys and achieving a sealing effect. In this embodiment, the end of the sealing plate bracket 7 where the flexible sealing plate 8 is mounted extends beyond the flexible sealing plate 8, forming an outwardly bent and expanded shape, thus creating the smooth bend 701. This allows the flexible sealing plate 8 to safely return to its original position, preventing scratches and damage during operation. Furthermore, these components can be installed in the factory in one step, achieving rapid installation, quick replacement, and safe operation, eliminating the need for on-site processing of the side panels and reducing installation and operating costs.

[0027] In one embodiment, the flexible sealing plate 8 has a downwardly and outwardly extending extension 801 at its bottom. This structure is used to implement a trolley structure and is adapted to the inclined surface at the bottom of the trolley. In another embodiment, two sealing plate supports 7 are provided on the lower frame 4. The bottom of the sealing plate supports 7 located at the lower part of the lower frame 4 is fixedly connected to a downwardly and outwardly inclined extension plate 702. The extension plate 702 is perpendicular to the sealing plate supports 7 and fits against the outer side of the extension 801 and is fixed by bolts.

[0028] In one embodiment, the flexible sealing plate 8 and the sealing plate bracket 7 are fixedly connected by bolts. A countersunk hole is provided on the inner side of the flexible sealing plate 8. After the bolt passes through the flexible sealing plate 8, it is fixedly connected to the sealing plate bracket 7 by a nut. The end of the bolt is fixed in the countersunk hole. Since the end of the bolt is fixed in the countersunk hole, the side of the flexible sealing plate 8 that is in contact with the gap is a smooth planar structure. The end of the bolt will not have any part protruding from this surface, which makes the flexible sealing plate 8 fit more tightly with the gap and the sealing effect is better.

[0029] Example 2 This embodiment is a further improvement based on Embodiment 1, with reference to... Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the trolley sideboard in this embodiment includes an upper sideboard 101 and a lower sideboard 102 of the same length. The lower sideboard 101 has a first flange 9 extending outward at its bottom, and the lower sideboard 102 has a second flange 10 extending outward at its top. The first flange 9 and the second flange 10 are fixedly connected. The mounting base plate 2 is fixedly connected to the upper side of the first flange 9 or the lower side of the second flange 10. Since the mounting base plate 2 is no longer sandwiched between the first flange 9 and the second flange 10, the length of the mounting base plate 2 does not have to be the same as that of the trolley sideboard. In this embodiment, the mounting base plate 2 is not the same length as the trolley sideboard; in embodiment one, the mounting base plate 2 is installed between the first flange 9 and the second flange 102 of the upper and lower sideboards 102, so it must be the same length as the trolley sideboard to avoid air leakage due to gaps caused by unequal lengths when the mounting base plate 2 is installed between the upper and lower trolley sideboards. In this embodiment, the mounting base plate 2 is installed at the bolt mounting position of the upper railing 101 or the lower railing 102. It is only fixed to the upper railing 101 or the lower railing 102 and is not located between the upper and lower railings 102, so it does not need to be the same length as the railing.

[0030] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
