Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste collection technology, specifically to a waste trough for converters. Background Technology
[0002] The waste trough for converters is a key transitional device connecting waste storage / transportation equipment and converters in the steelmaking process. It is mainly used to accurately and efficiently feed scrap steel and pig iron raw materials into the converter. Through the design of the tilt angle and the smoothness of the inner wall, the waste is guided to slide down along the preset path to ensure that the raw materials enter the converter accurately and avoid spillage.
[0003] In the existing technology, the equipment trough includes a head section, a tail section, and a transition section connecting the two. The top of the tail section is higher than the head section, and the height of the top of the transition section gradually decreases from the tail section to the head section. This structure can increase the trough volume without affecting the scrap steel trough entering the converter furnace mouth and without expanding the length and width of the scrap steel trough. At the same time, the increase in trough weight is small, reducing equipment investment and modification work. Converter steelmaking has high requirements for the accuracy of scrap steel addition. Traditional scrap troughs rely on external weighbridges for weighing, which has secondary lifting errors. Currently, weighing sensors (such as strain gauge sensors) are installed at the trunnion support structure of the trough to directly monitor the total weight of the trough and materials in real time. However, irregular deformation and weld cracking occur on the side walls and bottom of the trough, and in severe cases, through cracks are formed. Long-term high-frequency vibration causes bolts to loosen, which in turn causes stress concentration in the support and the inner lining to be loosely fixed to the shell and peel off after being impacted by raw materials. Utility Model Content

Long-term high-frequency vibration leads to loosening of bolts, which in turn causes stress concentration of the support, as well as the insecure fixing of the inner lining to the shell, which peels off after being impacted by raw materials.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a waste trough for a converter, comprising an inner lining 1, a support mechanism 2 installed on the inner side of the inner lining 1 for supporting the overall structure, and a vibration mechanism 3 installed on the inner bottom wall of the inner lining 1 to prevent waste from accumulating in the trough. The support mechanism 2 includes a fixing frame 202, which is fixedly connected to the left and right sides of the inner bottom wall of the inner lining 1. Fixing posts 204 are threadedly connected to the front and rear sides of the inner wall of the fixing frame 202.

Multiple crossbeams 201 are fixedly connected at equal intervals to the top wall of the fixing frame 202. A top frame assembly 206 is installed on the top wall of the beam 201. The top frame assembly 206 includes a connecting frame 2062, which is fixedly connected to the left and right sides of the top wall of the beam 201. Multiple connecting rods 2063 are fixedly connected at equal intervals in the upper middle part of the inner wall of the connecting frame 2062. Multiple support columns 205 are fixedly connected at equal intervals in the bottom wall of the connecting frame 2062. The ends of the support columns 205 are fixedly connected to the inner bottom wall of the inner lining layer 1. Multiple damping rods 2061 are installed at equal intervals in the upper middle part of the outer wall of the connecting frame 2062. The ends of the damping rods 2061 are connected to the top wall of the fixed frame 202. Multiple brackets 208 are fixedly connected at equal intervals in the top wall of the connecting frame 2062. Long plates 207 are installed on the top of the brackets 208.
[0032] Specifically, the fixing frame 202 is erected vertically on the ground at equal intervals. Then, the fixing column 204 is screwed into the threaded hole on the inner wall of the fixing frame 202 and inserted into the ground, so that the fixing frame 202 is tightly connected to the ground. The long plate 203 is tightly connected to the fixing frame 202 and the inner wall of the inner lining layer 1, which can simultaneously withstand bidirectional bending moment and shear force, enhance the stability of the structure under horizontal load, enhance the overall structure, and prevent the inner lining layer 1 from peeling off. Multiple crossbeams 201 are installed on the top of the fixing frame 202. The crossbeams 201 bear the weight of their top frame assembly 206. The bottom of the connecting frame 2062 has a support column 205 that can distribute some of the weight to the ground. The connecting rod 2063 shakes and compresses the connecting frame 2062. The connecting frame 2062 compresses the damping rod 2061. When the damping rod 2061 is subjected to vibration, it undergoes elastic deformation, absorbing and buffering vibration energy, effectively isolating vibration, avoiding loosening, wear or even damage of components due to long-term vibration, and extending the service life of the structure.
[0033] Reference Figure 1 , Figure 2 and Figure 5 The vibration mechanism 3 includes a slide rail 304, which is fixedly connected at equal intervals to the inner bottom wall of the inner lining layer 1. A slider 305 is slidably connected to the outer wall of the slide rail 304. A hollow block 303 is fixedly connected to the outer wall of the left slider 305. A bearing plate 306 is fixedly connected to the top wall of the slider 305. A fixing block 302 is provided on the left side of the slide rail 304. The fixing block 302 is fixedly connected to the left side of the inner bottom wall of the inner lining layer 1. A drive assembly 301 is installed on the top of the fixing block 302. The drive assembly 301 includes a motor 3013, which is fixedly connected to the top of the fixing block 302. A crank 3011 is fixedly connected to the output end of the motor 3013. A rotating shaft 3012 is rotatably connected to the right side of the outer wall of the crank 3011. The rotating shaft 3012 is slidably connected to the inner wall of the hollow block 303.
[0034] Specifically, the motor 3013 rotates to drive the crank 3011. The rotation of the crank 3011 causes the shaft 3012 at the end to move within the hollow block 303, thereby driving the bearing plate 306 to move back and forth on the slide rail 304. The back and forth movement of the bearing plate 306 generates vibration, causing the waste material accumulated in the bearing plate 306 to vibrate and disperse and fall, making the waste material more evenly distributed within the bearing plate 306 and preventing uneven waste distribution from clogging the tank.
[0035] Reference Figure 1 , Figure 2 and Figure 3 A heat insulation layer 5 is installed on the outer wall of the inner lining layer 1. The heat insulation layer 5 is fixedly connected to the outer wall of the inner lining layer 1. An outer shell 4 is installed on the outer wall of the heat insulation layer 5. The outer shell 4 is fixedly connected to the outer wall of the heat insulation layer 5.
[0036] Specifically, the inner lining 1 protects the shell from high-temperature corrosion and material wear, extending the life of the tank. The outer shell 4 serves as the core channel for waste material transportation, bearing the weight and impact of raw materials such as scrap steel and pig iron. The heat insulation layer 5 prevents the equipment base from deforming due to stress.
[0037] Working principle: The fixing frame 202 is erected vertically on the ground at equal intervals according to the design requirements. Then, the fixing column 204 is slowly screwed into the pre-machined threaded holes on the inner wall of the fixing frame 202, gradually penetrating into the underground soil layer until the fixing frame 202 forms a firm connection with the ground. During this process, the long plate 203 is tightly attached to the fixing frame 202 and the inner wall of the inner lining layer 1, forming a stable connection structure. This connection method allows the entire structure to withstand bending moments and shear forces from different directions simultaneously, significantly improving the stability of the structure under horizontal loads. This design not only enhances the overall integrity of the structure but also effectively prevents the inner lining layer 1 from peeling off. Multiple crossbeams are installed on the top of the fixing frame 202 according to the design requirements. 201. The main function of these crossbeams 201 is to bear the entire weight of the top frame assembly 206 above them. In order to further distribute the load, support columns 205 are set at the bottom of the connecting frame 2062. These support columns 205 can directly transfer part of the weight to the ground, reducing the burden on the crossbeams 201. When the connecting rod 2063 shakes, it will compress the connecting frame 2062, which will then put pressure on the damping rod 2061. When the damping rod 2061 is subjected to vibration, it will undergo elastic deformation. This deformation can effectively absorb and buffer vibration energy, achieving a good vibration isolation effect. This design can avoid problems such as component loosening, wear or even damage caused by long-term vibration, thereby significantly extending the service life of the entire structure.
[0038] After the motor 3013 starts, it drives the transmission crank 3011 to rotate. The rotation of the crank 3011 causes the shaft 3012 at its end to reciprocate within the hollow block 303, which in turn drives the bearing plate 306 to move back and forth along the slide rail 304. This reciprocating motion produces a continuous vibration effect, causing the waste accumulated in the bearing plate 306 to be gradually dispersed and sink downwards due to the vibration. Through this vibration method, it is possible to ensure that the waste is more evenly distributed in the bearing plate 306, effectively preventing the trough blockage problem caused by uneven waste distribution. The entire system achieves uniform distribution and smooth flow of waste through this mechanical vibration, ensuring the normal operation of the equipment and production efficiency.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
