DETAILED DESCRIPTION

[0033] The specific implementation of the utility model will be further explained in detail below. Figures 1-13

[0034] Example one, combining the drawings Figures 1-5 ​The application relates to a slag basin, which comprises a plurality of ladles 1 for containing materials, the plurality of ladles 1 are integrally made by casting processing, high-temperature molten slag is contained in the ladles 1 during use, the plurality of ladles 1 are combined to form the slag basin, and before hot molten slag is loaded, spraying material mixed with lime in a certain proportion is uniformly sprayed on the inner wall of the ladle 1. After the spraying treatment, the problem of residual molten steel sticking to the ladle 1 in the steel slag is solved, and the service life of the ladle 1 is greatly improved. Through the combination of the plurality of ladles 1, the problem that high-temperature molten slag is still an integral whole after the traditional slag basin is cooled, so that the high-temperature molten slag needs to be cut subsequently and the molten slag is inconvenient to pour when the volume of the molten slag is too large is avoided. The combined slag basin has a more diversified structure and can meet the requirements of different volumes, so the applicability is wider. Specifically, refer to the accompanying drawings Figure 1 and the accompanying drawings Figure 3 respectively show the structure of the arrangement of the ladles 1 and the arrangement of multiple rows, and the preset structure is shown in the accompanying drawings Figure 4The pot basin 1 specifically includes a frame-type connecting part 1-1 and an integrated receiving part 1-2. The pot basin 1 is inverted trapezoidal in shape, meaning the upper part is a frame structure and the lower part is an inverted trapezoidal structure. Multiple pot basins 1 are arranged and combined via the frame-type connecting parts 1-1. After multiple pot basins 1 are combined, the receiving parts 1-2 are all exposed at intervals. At least one set of heat dissipation fins 7 is provided around the perimeter of the pot basin 1 to enhance its heat dissipation effect. This design ensures the connection of the pot basin 1 while accelerating the cooling of the molten slag inside the pot by exposing the receiving parts 1-2. Specifically, the heat dissipation fins 7 can be arranged in a crisscross pattern as needed, and the heat dissipation fins are arranged along the direction of the heat dissipation airflow. To improve heat dissipation, the frame-shaped connecting part 1-1 is provided with ventilation holes 4 positioned between two adjacent receiving parts 1-2. These ventilation holes 4 serve a heat dissipation function during slag pot hoisting. The bottom of each receiving part 1-2 is rounded at each adjacent junction; a larger radius facilitates the detachment of high-temperature molten slag from the slag pot. The inverted receiving parts 1-2 and the rounded transition at the connection points make it easy to pour out the molten slag. Multiple frame-shaped connecting parts can be cast or welded to form multiple pots as a single unit. The height of the frame-shaped connecting part 1-1 is 28%-35% of the height of the pot 1, ensuring that the receiving parts are all exposed at intervals after multiple pots are connected and assembled. The exterior of the accommodating part of the pot basin forms a smooth convection space, which is conducive to the rapid cooling of high-temperature molten slag. When the high-temperature molten slag cools rapidly, the part of the high-temperature molten slag in contact with the inner surface of the accommodating part of the pot basin cools into a hard shell first, which is easy to peel off from the pot basin. In this embodiment, a connecting groove 2 is also provided on the frame-type connecting part 1-1. The connecting groove 2 can be embedded in the supporting beam 3. Pre-set, the supporting beam 3 is used to connect the slag basin after the pot basin 1 is assembled with the lifting device for lifting. In this embodiment, preferably, the connecting groove 2 is symmetrically arranged on both sides of the frame-type connecting part 1-1, and does not communicate with the inner cavity of the pot basin 1. The supporting beam 3 is embedded or welded to the connecting groove 2 in an interference fit manner. The support beam 3 is installed into the connecting groove 2, and it is also easy to disassemble the support beam 3. A single support beam 3 is used in the corresponding connecting grooves 2 between two adjacent pot basins 1. It also includes lifting lugs 6 on the pot basin 1. The lifting lugs 6 are pre-installed on the side wall of the pot basin 1 without connecting grooves 2, facilitating the lifting and flipping of the connected pot basin 1. In this embodiment, the optimal choice is for multiple pot basins 1 to be integrally formed as a slag basin, which ensures the strength of the slag basin. However, this embodiment also provides another structure that allows the pot basins 1 to be individually set and then spliced ​​together to form a slag basin. Specifically, it also includes a connecting frame 5 for disassembling and assembling multiple pot basins 1. (See attached diagram). Figure 6 and attached Figure 7The connecting frame 5 is manufactured according to the arrangement mode of the specific pot 1, the plurality of pot 1s are embedded into the connecting frame 5 and are bolted, and the connecting frame 5 is bolted with the supporting waist plate 5. This arrangement can improve the applicability of the slag basin. The plurality of pot 1s are detachably connected and combined. Compared with the integrally formed slag basin, the pot 1s can be conveniently replaced subsequently, but the connection strength is weaker than that of the integrally formed slag basin. Users can select according to actual needs.

[0035] In the embodiment, when the plurality of pot 1s are arranged separately and combined, it is necessary to mention that the pot 1s can be arranged as a unified structure, that is, a group of connecting grooves 2 are symmetrically arranged on the frame-shaped connecting part 1-1, a group of supporting waist plates 4 are symmetrically arranged on each side of each connecting groove 2, and a group of lifting lugs 6 are symmetrically arranged. In this way, the direction problem when the pot 1s are combined can be solved during actual assembly. In contrast, the pot 1s in the embodiment can also be arranged as a plurality of modules with different structures. That is, only one connecting groove 2 can be arranged on the pot 1s at the two ends, and only one supporting waist plate 4 can be arranged on each side of each connecting groove 2. The supporting waist plate 4 is arranged at a position such that the supporting waist plates 4 on the two adjacent pot 1s can be located on the same side to satisfy the connection with the limiting plate 5. In addition, only one lifting lug 6 can be arranged, or only one lifting lug 6 can be arranged on all the pot 1s after combination. As long as the overall overturning of the pot 1s can be satisfied, the lifting lug 6 can be arranged.

Specifically, for the arrangement of the plurality of pot 1s described in the attached Figure 1 , a group of lifting hooks 9 are hinged to the lifting beam 8. Specifically, for the arrangement of the plurality of pot 1s described in the attached Figures 8-11, the support beam 3 placed on the two side ends of the pot basin 1 is placed in the hook groove 10 of the lifting hook 9, that is, in the slag basin spliced by embodiment one, the support beam 3 is embedded in the connecting groove 2 of the two pot basins 1 located at the two most side edges, the two support beams 3 are respectively supported by the lifting hook 9, and the function of lifting the slag basin by the crane is realized. It is predetermined that, in order to prevent the support beam 3 from slipping out of the connecting groove 2 during lifting, the connecting beam is provided with an annular groove 11, and the annular groove 11 is limited and matched with the limiting table 12 arranged on the lifting hook 9, that is, when the support beam 3 is placed in the lifting hook 9, the annular groove 11 on the support beam 3 will be matched with the limiting table 12 on the lifting hook 9, and the support beam 3 is limited from slipping out of the connecting groove 2 by the limiting table 12 placed in the annular groove 11, so as to ensure the stability during lifting. Through the above structure, after the pot basins 1 in the slag basin are fixedly connected by the limiting plate 5, the pot basins 1 in the slag basin will become a whole and be lifted by the lifting tool. In order to realize the overturning of the slag basin, the lifting lug 6 is rotationally connected with a lifting buckle 13, the lifting buckle 13 is connected with a winch arranged on the lifting beam 8 through a lifting chain, the winch is retracted and tensioned to drive the slag basin to rotate around the support beam 3 on the lifting tool, so that the molten slag in the pot basin 1 is poured, and meanwhile, when a plurality of pot basins 1 are arranged in multiple rows and arranged in parallel, referring to Figure 3 , the connecting groove 2 is always arranged on the central axis of the slag basin after the plurality of pot basins 1 are combined, so that the lifting of the slag basin is completed by a group of lifting hooks 9 hinged on the lifting beam 8.
