Description
Technical Field
[0001] The utility model relates to the technical field of material preparation equipment, and more specifically, to a primary cooling section granulation device. Background Art
[0002] Slag is a by-product of the ironmaking / ferroalloy production process and contains abundant resources. The treatment process of high-temperature slag generally involves first granulating the high-temperature melt using a slag granulator, and then reprocessing the granulated particles to achieve product reuse.
[0003] At present, the granulation of high-temperature slag generally requires granulation in the primary cooling stage, and the high-temperature slag after the primary cooling stage is continuously passed through the subsequent secondary or multiple cooling to obtain granular slag with a lower temperature, and then unloaded. However, in the actual process, it is found that after the high-temperature melt is granulated by the granulation device, the temperature of the granulated slag in the primary cooling stage is about 800°C. The granular slag at about 800°C has reached a temperature below the mineral crystallization temperature and can also be unloaded, thereby saving the subsequent secondary or multiple cooling processes.
[0004] The discharge port of the current primary cooling section granulation device is a ring channel. If the granular slag falls directly along the ring channel during discharge, the fallen granular slag needs to be continuously collected to meet the requirements of industrial continuous production. However, the granular slag at about 800°C falls vertically from the ring channel at 360°. If it falls directly on the ground and is then collected, there are certain requirements for the amount of slag and the collection speed of the granular slag on the ground. In addition, 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. Therefore, it is urgently necessary to develop an effective solution to solve the difficulty of direct discharge of the granulation device in the primary cooling section. Utility Model Content

[0036] like Figures 1 to 8 As shown together, the primary cooling section granulation device provided by the utility model comprises a granulation chamber 1, wherein a hot slag annular discharge device is arranged at the annular discharge port 11 of the granulation chamber 1; the hot slag annular discharge device comprises a turntable device 2, a material guiding device, a supporting device and a driving device 5; the turntable device 2 comprises a body section 21, an annular groove 22 arranged at the top of the body section 21 and a heat-insulating refractory material layer 23 arranged at the bottom of the annular groove; the receiving port of the annular groove 22 is opposite to the annular discharge port 11 of the granulation chamber 1; the material guiding device comprises a scratching plate 31 fixedly arranged at a preset discharge position, and the scratching plate 31 is inclined. It is arranged above the annular groove 22, and a material guiding channel 32 is formed between the inclined direction of the sliding plate 31 and the outer edge of the turntable device and the preset unloading position; a unloading chute 33 is arranged at the preset unloading position, and the lower end of the unloading chute 33 is connected to a storage device; the supporting device includes an inner supporting roller 41 arranged at the bottom of the inner ring of the main body section 21 and an outer supporting roller 42 arranged at the bottom of the outer ring of the main body section; the driving device 5 includes a driving mechanism 51, a transmission gear 52 sleeved on the upper part of the driving mechanism 51 and a pin tooth 53 arranged on the outer side wall of the turntable device; the transmission gear 52 is meshed with the pin tooth 53.
[0037] The annular groove 22 is a C-shaped groove structure formed by an inner ring plate 221 disposed on the inner ring side of the body segment 21 and an outer ring plate 222 disposed on the outer ring side of the body segment 21. Both the inner ring plate 221 and the outer ring plate 222 are steel plate structures, preferably but not limited to being fixed on the top surface of the body segment 21 by welding.
[0038] The preset unloading position in the utility model can be set according to actual needs. The scraper 21 is fixed at the preset position and is located above the turntable device 1.

At this time, a receiving device or a storage device can be set in advance at the unloading position. The material device receives the high-temperature hot granular slag dropped from the preset unloading position, so as to complete the annular dropping of the high-temperature granular slag produced in the granulation chamber, thereby avoiding the collection difficulty caused by the 360° vertical dropping of the existing primary cooling section granulation device. The utility model can solve the problem that in the slag granulation process, the high-temperature hot granular slag in the primary cooling section cannot be directly received by the receiving device or the storage device due to the 360° vertical drop, and directly falls to the ground, causing damage to the ground, and the amount of the high-temperature hot granular slag dropped and the storage time on the ground are limited, thereby causing the granulation device to be unsuitable for the continuous production of batch granular slag.
