[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a special molten iron ladle structure for molten steel pretreatment, including a steel outer shell 1, a transfer mechanism 2, and a protective mechanism 3. The transfer mechanism 2 is located at the bottom of the steel outer shell 1 and includes a hollow support block 201 and moving wheels 202. The bottom of the steel outer shell 1 is in contact with the inner wall of the hollow support block 201, and multiple sets of moving wheels 202 are fixedly installed on the outer wall of the hollow support block 201. The protective mechanism 3 is located at the top of the steel outer shell 1 and includes a connecting plate 301 and a rotating shaft 3. 02. Movable plate 303 and partition cover 304. Two sets of connecting plates 301 are fixedly installed on the outer wall of the steel shell 1. A set of rotating shafts 302 are rotatably installed on the adjacent sides of the connecting plates 301. One end of the two sets of rotating shafts 302 is fixedly connected to the front and rear sides of the movable plate 303 respectively. The bottom of the movable plate 303 is fixedly connected to the top of the partition cover 304. Two sets of lifting lugs 4 are fixedly installed on the outer wall of the steel shell 1. A discharge nozzle 6 is provided on the top of the steel shell 1. A fire-resistant lining 5 is fixedly installed on the inner wall of the steel shell 1.
[0023] Secondly, the transfer mechanism 2 also includes a threaded rod 203, a fixing block 204, and a positioning hole 205. Two sets of fixing blocks 204 are fixedly installed on the outer wall of the steel shell 1. The front side of the fixing block 204 has a through positioning hole 205. The front and rear sides of the hollow support block 201 are respectively threaded with a set of threaded rods 203. One end of the threaded rod 203 extends into the interior of the positioning hole 205, and the other end of the threaded rod 203 is provided with a knob, providing more transfer methods. When there is no molten iron, it can be easily moved without hoisting equipment. It is also relatively simple to disassemble, which is convenient for the staff to operate and improves the usability and practicality of the device.
[0024] Furthermore, the protective mechanism 3 also includes a hinge block 305 and a high-temperature resistant hydraulic cylinder 306. A set of hinge blocks 305 is fixedly installed on the outer wall of the steel shell 1. The high-temperature resistant hydraulic cylinder 306 is hingedly installed inside the set of hinge blocks 305. Another set of hinge blocks 305 is fixedly installed on the bottom of the movable plate 303. The free end of the high-temperature resistant hydraulic cylinder 306 is hingedly connected to the inside of the other set of hinge blocks 305 through a circular block. The partition cover 304 is made of high-temperature resistant material. When loading molten iron, it covers the surface of the device, slows down the rate of heat loss from the molten iron, prevents molten iron from spilling out of the device, reduces the probability of workers being burned, and improves the safety of the device during use.
[0025] Working principle: During normal use, the device can be moved using the movable wheels 202. When the movable wheels 202 are not needed, the two sets of threaded rods 203 are rotated to move them on the hollow support block 201. One end of the threaded rod 203 is moved out of the positioning hole 205, thus removing the limit on the fixed block 204. The device is then lifted by the lifting lug 4, separating the steel outer shell 1 from the hollow support block 201. This allows the movable wheels 202 to be removed from the device. Molten iron is then poured into the refractory lining 5 for storage. The high-temperature hydraulic cylinder 306 is extended, causing it to rotate between the two sets of hinge blocks 305. This causes the movable plate 303 to rotate between the connecting plates 301, thereby covering the top of the steel outer shell 1 with the partition cover 304 to prevent the molten iron from spilling out. The device can then be lifted to a designated location using hoisting equipment.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
