Description

Technical Field

[0001] The utility model relates to the technical field of material preparation, and more specifically to a centering system of a ring-shaped discharge device for granulated hot slag in a primary cooling stage. Background Art

[0002] Slag is a by-product of the ironmaking / ferroalloy production process and contains abundant resources. The treatment process of high-temperature molten slag generally uses a slag granulation device to granulate the high-temperature melt, and the granulated particles are reprocessed to achieve product reuse. The traditional granulation process generally includes granulation in the primary cooling stage and secondary cooling or multiple cooling of the granulated slag after granulation in the primary cooling stage until the granulated slag reaches the discharge temperature before discharge.

[0003] In the actual granulation process, after the high-temperature melt is granulated by the granulation device, the temperature of the granulated slag in the primary cooling section is about 800°C. The granular slag at about 800°C has reached a temperature below the mineral crystallization temperature and can be unloaded, thus saving the subsequent secondary or multiple cooling processes. When unloading, the granular slag falls along a circle of annular channels of the granulation device. The fallen granular slag needs to be continuously collected to meet the requirements of industrial continuous production.

[0004] The granular slag at about 800°C falls vertically from the annular channel at 360°. If it falls directly on the ground and is then collected, there are certain requirements on the amount of slag and the collection speed of the granular slag on the ground, and the ground where the granular slag falls will be damaged to a certain extent, which is not suitable for the continuous production of batch granular slag. Based on the above problems, our unit has proposed an annular unloading device, which uses an annular unloading plate to receive the high-temperature granular slag falling vertically from the annular unloading channel of the granulating device, and then rotates the annular unloading plate to unload the granular slag at a preset unloading position using a preset scratching plate. In this process, the annular unloading plate needs to rotate continuously. Due to the large size of the annular unloading plate, it is difficult to control the displacement during continuous rotation, resulting in the inability to accurately receive the material dropped by the granulating device and it is difficult to ensure that the unloading is completed at the preset unloading position, thereby affecting the normal unloading process. At present, the rotary unloading of the primary cooling section in the prior art is still in a blank stage, so there is a lack of an effective solution that can prevent eccentric displacement of the annular unloading plate during continuous rotation.

[0035] In order to explain the centering system of the annular discharge device for granulated hot slag in the primary cooling stage provided by the utility model, Figure 1 The top view structure of the installation of the centering system of the annular discharge device for hot granulated slag in the primary cooling stage according to the embodiment of the utility model is shown; Figure 2 The top view installation structure of the centering device according to the embodiment of the utility model is shown; Figure 3 A side view installation structure of a centering device according to an embodiment of the utility model is shown; Figure 4 The side view structure of the swing frame according to the embodiment of the utility model is shown; Figure 5 The front view structure of the swing frame according to the embodiment of the utility model is shown; Figure 6 The overall side structure of the centering device according to the embodiment of the utility model is shown; Figure 7 The structure of the buffer mounting seat according to the embodiment of the utility model is shown; Figure 8 The structure of the fixed base according to the embodiment of the utility model is shown; Fig. 9 The structure of the buffer base according to the embodiment of the utility model is shown.

[0036] like Figures 1 to 9 As shown together, the centering system of the annular unloading device of granulated hot slag in the primary cooling stage provided by the utility model comprises at least one pair of centering devices 1 relatively arranged on the inner side of the annular unloading plate 2 of the annular unloading device; the centering device 1 comprises a base bracket 11, a centering roller 12, a centering roller pin 13, an elastic buffer mechanism 14, a swing frame 15 and a swing frame pin 16; wherein, the centering roller 12 is vertically arranged, and the centering roller 12 is hinged to the swing frame 15 through the centering roller pin 13; the centering roller 12 abuts against the inner side wall of the annular unloading plate 2; the swing frame 15 is hinged to the base bracket 11 through the swing frame pin 16; the elastic buffer mechanism 14 is connected to one end of the inner side of the swing frame 15, and the centering roller 12 is pressed against the inner side wall of the annular unloading plate 2 through the swing frame 15; a limiting mechanism is arranged on the base bracket 11, and the limiting mechanism abuts against the other end of the inner side of the swing frame 15.

[0037] The centering system may further include a centering ring 17 disposed at the bottom of the annular discharge tray 2 of the annular discharge device, and the centering roller 12 abuts against the inner wall of the centering ring 17, and the centering roller 12 is pressed against the inner wall of the centering ring 17 by the swing frame 15.

[0042] It should be noted that the structure of the above-mentioned swing frame 15 is only a preferred structure of the utility model. The structure of the swing frame 15 can be changed according to actual needs. As long as the buffering and elastic force provided by the elastic buffer mechanism 14 are ensured so that the swing frame 15 can press the centering roller 12 tightly against the inner wall of the annular discharge plate 2 (centering ring 17), the utility model does not make any special limitation on this.

[0043] As a preferred solution of the present invention, the upper triangular fixing plate 151 and the lower triangular fixing plate 152 are both integrated structures. That is, the upper triangular fixing plate 151 is an integrated structure as a whole, and the lower triangular fixing plate 152 is an integrated structure as a whole, which can be obtained by mold processing, so that the overall structure is more solid and durable. Of course, the upper triangular fixing plate 151 and the lower triangular fixing plate 152 can also be divided into multiple parts and obtained by welding, which is not particularly limited by the present invention. The material of the upper triangular fixing plate 151 and the lower triangular fixing plate 152 is preferably, but not limited to, steel plate.

[0044] As a preferred solution of the present invention, the two ends of the connecting sleeve 153 are respectively welded to the first upper shaft hole and the first lower shaft hole. The connecting sleeve 153 is preferably but not limited to being made of steel, and its two ends can be respectively fixed to the first upper shaft hole and the first lower shaft hole by welding. The first upper shaft hole and the first lower shaft are located in a corresponding position, so that the swing frame pin 16 is vertically inserted into the connecting sleeve 153.

[0045] As a preferred solution of the utility model, a scale 141 is provided on the elastic buffer mechanism 14, and a scale pointer 142 is provided at one end where the elastic buffer mechanism 14 is connected to the swing frame 15; the scale pointer 142 is provided at the lower part of the scale 141 and corresponds to the scale on the scale 141.

[0046] Through the scale 141 and the scale pointer 142, the expansion and contraction amount of the elastic buffer mechanism 14 can be observed, and then the offset amount of the annular discharge tray 2 can be inferred. The preset position of the swing frame 15 can be adjusted by limiting, so that the offset position of the annular discharge tray 2 can be adjusted according to the working conditions.

[0047] As a preferred solution of the utility model, a buffer mounting seat 3 is arranged at the tail end of the elastic buffer mechanism 14; the buffer mounting seat 3 includes a fixed base 31 fixed on a concrete foundation and a buffer base 32 detachably fixed to the top of the fixed base 31; an elastic buffer mechanism fixed mounting portion is arranged on the top of the buffer base 32.

[0048] Specifically, the fixed base 31 can be detachably fixed on the concrete foundation by fixing bolts, and the position of the buffer base 32 on the top of the fixed base 31 can be adjusted by a detachable part, thereby adjusting the compression amount of the elastic buffer mechanism 14. The tail end of the elastic buffer mechanism 14 refers to the end opposite to the inner connection end of the swing frame 15.

[0049] As a preferred solution of the utility model, a sleeve ring 5 is provided at the tail of the elastic buffer mechanism 14 ; the fixed installation part of the elastic buffer mechanism includes a vertical shaft 321 provided on the top of the buffer base 32 ; the sleeve ring 5 is sleeved on the vertical shaft 321 .

[0050] The sleeve ring 5 facilitates the tail of the elastic buffer mechanism 14 to be fixed on the vertical axis 321 at the top of the buffer base 32 , so that the compression amount of the elastic buffer mechanism 14 can be adjusted by adjusting the position of the buffer base 32 on the top of the fixed base 31 .

[0051] As a preferred solution of the utility model, a first long hole is provided on the top of the fixed base 31 , and a second long hole 322 is provided on the buffer base 32 ; the first long hole and the second long hole 322 are connected by bolts 323 .

[0052] The position of the buffer base 32 on the top of the fixed base 31 is conveniently adjusted by fixing the connection with the long hole. Of course, it can also be replaced by other structures. For example, by setting a plurality of pin holes with relative positions on the fixed base 31 and the buffer base 32, and then adjusting the corresponding relationship between the pin holes on the fixed base 31 and the buffer base 32, the two are detachably fixedly connected by using fixing pins. The utility model does not make any special limitation on this, and the detachable connection method of the two can be selected according to actual needs.

[0053] As a preferred solution of the utility model, a vertical fixing plate 311 is provided at the inner end of the fixed base 31, and a first bolt mounting hole 3111 is horizontally opened on the vertical fixing plate 311; a first adjustable bolt 3112 is provided in the first bolt mounting hole 3111; one end of the first adjustable bolt 3112 located in the fixed base 31 abuts against the outer wall of the buffer base 32.

[0054] The first adjustable bolt 3112 further fixes the buffer base 32 to prevent the buffer base 32 from shifting due to the long hole and loose bolt fixation after the position of the buffer base 32 is determined.

[0055] As a preferred solution of the utility model, the limiting mechanism includes a vertical plate 7 arranged on the top of the base bracket 11; a second bolt mounting hole 71 is provided on the vertical plate 7; a second adjustable bolt 72 is passed through the second bolt mounting hole 71; a stopper 6 is fixedly provided at the end of the long side plate of the swing frame 15; and the adjustable end of the second adjustable bolt 72 abuts against the stopper 6.

[0056] It should be noted that the limiting mechanism can be set as the above structure, and the stop block 6 and the second adjustable bolt 72 are used to limit the swing frame 15, so that the centering roller 12 is pressed tightly against the inner wall of the annular unloading plate 2 (centering ring 17). Of course, other structures can also be used as replacements, such as setting a limiting frame, a limiting block and other structures on the top of the base bracket 11, and the present invention does not make any special limitations on this.

[0057] As a preferred solution of the present invention, the elastic buffer mechanism 14 is a spring device. The elastic buffer mechanism 14 is preferably but not limited to a spring device.

[0058] When the annular unloading device for granulated hot slag in the primary cooling stage performs rotational unloading through the annular unloading plate 2, the rotation of the annular unloading plate 2 is positioned by the centering system of the annular unloading device for granulated hot slag in the primary cooling stage as described above provided by the utility model to avoid positional deviation when the annular unloading plate 2 rotates.

[0059] In a preferred embodiment of the present invention, the centering devices 1 are preferably three pairs, that is, six. Figure 1As shown, they are evenly arranged on the inner side of the annular discharge tray 2. Since there may be installation errors in the position of the swing frame 15 of the centering device 1 during installation, the centering roller 12 can be made to rest against the inner side of the annular discharge tray 2 by adjusting the position of the buffer base 32 of the elastic buffer mechanism 14; the compression amount of the elastic buffer mechanism 14 can be adjusted by adjusting the second adjustable bolt 72 above the base bracket 11 that contacts the block 6 on the swing frame 15, and the compression amount can be measured by the scale 141 and the scale pointer 142; this process makes the compression amount of the six elastic buffer mechanisms 14 consistent, completing the centering of the annular discharge tray 2 before work; when the annular discharge tray 2 is subjected to uneven force and displaced, the centering roller 12 is subjected to force, and the elastic buffer mechanism 14 is compressed, thereby ensuring the overall stability of the annular discharge device.

[0060] It can be seen from the above specific implementation methods that the centering system of the annular unloading device for granulated hot slag in the initial cooling stage provided by the utility model centers the annular unloading disk by installing a centering device in pairs on the inner side of the annular unloading disk to ensure that the rotation center of the annular unloading disk will not shift during the continuous rotation process; the centering roller is vertically arranged and abuts against the inner wall of the annular unloading disk, the swing frame is hinged on the base bracket through a swing frame pin, and the centering roller is hinged to the swing frame through the centering roller pin, so that the centering roller can rotate along the centering roller pin connected to the swing frame, and the centering roller and the swing frame can also swing along the swing frame pin, and the centering roller and the swing frame can also swing along the swing frame pin, and the swing frame of the paired centering device on the inner side of the annular unloading disk is adjusted to a suitable position so that the centering roller abuts against the preset centering position of the inner side of the annular unloading disk, and then combined with the buffering force given by the elastic buffer mechanism, the position of the rotation center of the annular unloading disk is determined when the annular unloading disk rotates, so as to avoid eccentricity when the annular unloading disk rotates, thereby ensuring the normal unloading process of the annular unloading disk.
