Description

Technical Field

[0001] The present invention belongs to the technical field of steel slag treatment, and particularly relates to a spreading device for a steel slag ladle truck. Background Art

[0002] In the existing process of steel slag treatment in the metallurgical industry, generally, the ladle truck transports the steel slag to the treatment workshop and directly dumps it into the slag pool. The slag pool is generally lower than the ground where the ladle truck is located. The dumped steel slag piles up in a heap. Since the temperature of the molten steel slag is as high as over 1000 °C, it is easy to form large lumps of steel slag after cooling when piled together. Then, an excavator is used to rake the slag and cool it. The high temperature and dust at the site make the working environment poor and unsafe, and the high temperature causes the tires of the excavator to age extremely easily. Moreover, although the slag is raked and cooled by the excavator, there will still be large lumps of coagulated steel slag, resulting in the need for subsequent high-intensity operations such as cutting and crushing the steel slag before it can be used, which greatly wastes resources and pollutes the environment. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a spreading device for a steel slag ladle truck, which solves the problem that the existing dumping method is concentrated, resulting in a large block diameter of the solidified steel slag and making the subsequent treatment of the steel slag difficult.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A spreading device for a steel slag ladle truck includes a ladle truck and a spreading device. The ladle truck includes a slag ladle and a frame. The spreading device is arranged below the slag ladle and includes a guiding device, a spreading roller and a bracket. The guiding device and the spreading roller are arranged on the bracket. The bracket is connected to the frame. The guiding device is arranged above the spreading roller and is inclined in the horizontal direction with respect to the spreading roller. The spreading roller is connected to a driving device.

[0005] Further, the guiding device includes a guiding plate. The guiding plate is fan-shaped and the fan-shaped opening becomes larger near the spreading roller. The fan-shaped arrangement of the guiding plate makes the spreading area of the steel slag larger after dumping and cools faster.

[0006] Further, the guiding plate is provided with rib plates and baffles. The guiding grooves formed by the ribs are in an inverted "V" shape structure. A plurality of the guiding grooves are distributed in a tower layout. The guiding grooves divide the inside of the guiding plate into several small steel slag flow channels, and each channel is blocked by the rib plates, making the steel slag easy to cool and easy to separate into small block-shaped slag bodies, so that the molten steel slag is initially divided and broken on the guiding plate. The baffles are arranged on both sides of the guiding plate to prevent the molten steel slag from splashing out, playing a safety protection role.

[0007] Furthermore, grooves are circumferentially and evenly arranged on the roller of the spreading roller. The grooves are trapezoidally inverted, and the bottom of the grooves is set as an arc surface. The arc-shaped bottom of the grooves makes it easier for the poured steel slag to peel off.

[0008] Furthermore, the groove width of the diversion groove close to the spreading roller corresponds to the width of the groove, so that the steel slag enters the corresponding groove of the spreading roller from the diversion groove of the diversion plate, and is subjected to secondary segmentation and crushing. As the spreading roller rotates, the steel slag is divided into small pieces and evenly spread out.

[0009] Furthermore, a spraying mechanism is arranged on the frame. The spraying mechanism includes a spray head, and the spraying direction of the spray head is set facing the diversion plate. The spray head can spray anti-adhesion lime water or carbon powder on the diversion plate and the spreading roller after the first slag pouring.

[0010] Furthermore, a water pipe is axially arranged inside the spreading roller. The water pipe runs through the length direction of the spreading roller, and the water pipe is connected to the water supply system on the frame. A water pipe is arranged inside the spreading roller for cooling, so that the steel slag cools down faster.

[0011] Furthermore, a bearing seat and a buffer device are arranged on the bracket. The diversion plate is connected to the bracket through the buffer device. The buffer device is arranged below and in the horizontal direction of the bearing seat to connect with the bracket, so as to avoid the damage of the diversion plate and the spreading roller caused by the impact force of large pieces of steel slag when the steel slag is dumped.

[0012] Furthermore, the buffer device is a spring. Beneficial effects

[0013] During the working process of the device, first, the molten steel slag is initially segmented and crushed by the diversion plate, and then it is evenly spread out after being segmented and crushed again by the grooves of the spreading roller. The blocks formed by the spread steel slag are smaller and can meet the needs of the subsequent slag smothering process without further crushing. Moreover, during the spreading process, a water pipe is arranged inside the spreading roller shaft for cooling, so that the steel slag is crushed and cooled during the dumping process, improving the efficiency of the entire production process.

Detailed implementation manners

[0018] The following further elaborates on the detailed implementation manners of the present invention. It should be noted that, without conflict, the embodiments and the features in the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. Figures 1-3

[0019] Figures 1-3 Embodiment, in conjunction with the attached There is provided a spreading device for a steel slag ladle car, including a ladle car 1 and a spreading device 2. The ladle car includes a slag ladle 11 and a frame 12. The ladle car is equipped with hydraulic drive and a tipping and locking device for the slag ladle. The spreading device 2 is arranged below the slag ladle 11 to facilitate the tipping and flow of the steel slag. It includes a guiding device, a spreading roller 22 and a bracket 23. The guiding device and the spreading roller 22 are fixedly installed on the bracket 23 and can be connected by high-strength bolts for easy disassembly. The bracket in this technical solution is a generalized bracket, and all connecting parts used to install and connect the guiding device and the spreading roller 22 are part of the bracket. The guiding device is fixedly connected to the bracket 23 by bolts for easy disassembly, cleaning and replacement. The spreading roller 22 is rotatably connected to the bracket 23 through bearings. The bracket 23 is fixedly connected to the frame 11 by bolts. The guiding device is arranged above the spreading roller 22, and the guiding device and the spreading roller 22 are arranged obliquely in the horizontal direction, with the inclination angle set to be greater than 45° and less than 90° to facilitate the flow of the steel slag. One end of the shaft head of the spreading roller 22 is connected to a driving device, and the power of the driving device can be provided by the power on the ladle car 1 or a separate power drive can be set on the bracket 23.

[0020] The guiding device includes a deflector 21. The deflector 21 is fan-shaped and the fan-shaped opening becomes larger near the spreading roller 22. The fan-shaped arrangement of the deflector 21 increases the spreading area after the steel slag is tipped, enabling faster cooling.

[0021] The deflector 21 is provided with a plurality of rib plates 211 to form diversion grooves and baffles 212. The diversion grooves are in an inverted "V" shape structure, and a plurality of diversion grooves are distributed in a tower layout. The depth of the diversion grooves should not be too deep, and the specific depth can be set according to the coagulation characteristics of different metallurgical slags. The diversion grooves divide the inside of the deflector 21 into several small steel slag flow channels, and each channel is separated by the rib plate 211, making the steel slag easier to cool and easier to separate into smaller slag blocks, so that the molten steel slag is initially segmented and broken on the deflector 21. The baffles 212 are arranged on both sides of the deflector 21 to prevent the molten steel slag from splashing out.

[0022] The roller 221 of the spreading roller 22 is circumferentially and evenly provided with grooves 222. The grooves 222 are trapezoidal in reverse, and the bottom of the grooves 222 is set as an arc surface. The bottom of the grooves 222 is provided with an arc, so that the poured steel slag is easier to peel off.

[0023] The groove width of the diversion groove near the spreading roller 22 corresponds to the width of the groove 222, so that the steel slag enters the corresponding groove 222 of the spreading roller 22 from the diversion groove of the diversion plate 21, and is subjected to secondary crushing and segmentation. As the spreading roller 22 rotates, the steel slag is divided into small pieces and evenly spread out, and the cooling is faster.

[0024] A spraying mechanism is arranged on the frame 12. The spraying mechanism is connected to the water tank through a pipeline. The spraying mechanism includes a spray head 3. The spraying direction of the spray head 3 is set facing the diversion plate 21. The spray head 3 is provided with a valve switch control, and the valve switch can be manually or automatically controlled according to actual needs. Lime water or carbon powder for anti-adhesion can be sprayed on the diversion plate 21 and the spreading roller 22 after the first slag pouring.

[0025] A water pipe 4 is arranged axially inside the spreading roller 22. The water pipe 4 runs through the entire length direction of the spreading roller 22. The water pipe 4 is connected to the water supply system on the frame 12. The water supply system includes components such as a water pump, a water tank, and a valve for the internal circulation of the water pipe. The two shaft heads of the spreading roller 22 are connected to the water pipe through a rotary joint 5, which not only ensures the rotation of the spreading roller 22 but also does not affect the setting of the water pipe inside the spreading roller. The steel slag is cooled faster by the circulating water inside the water pipe.

[0026] A buffer device and a bearing seat 7 are arranged on the bracket 23. The buffer device is a spring 6. The diversion plate 21 is connected to the bracket 23 through the spring 6. Springs 6 are arranged both below the bearing seat where the spreading roller 22 is rotationally connected and horizontally connected to the bracket 23, so that the bearing seat is in a floating state in the vertical direction when receiving a large impact force, avoiding the damage to the diversion plate 21 and the spreading roller 22 caused by the impact force of large pieces of steel slag when the steel slag is poured. The elastic buffer in the horizontal direction avoids material jamming between the diversion plate 21 and the spreading roller 22; a protective plate 8 is arranged between the outer side of the bearing seat 7 and the shaft head of the spreading roller 22 to protect the bearing from the entry of splashed steel slag. The power drive of the spreading roller 22 belongs to common knowledge and is not limited. It can be driven by a motor or by hydraulic pressure, and can be considered according to the overall layout.

[0027] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: During operation, the ladle carrier 1 transports the steel slag to the slag pond. The ladle carrier 1 tilts the slag ladle 11 at a certain angle and locks it to dump the steel slag. The ladle carrier 1 is equipped with a tilting and locking mechanism for the slag ladle 11. The steel slag flows out of the slag ladle 11 onto the deflector 21, and after being divided, initially segmented and crushed by the diversion trough, it falls onto the spreading roller 22. The groove 222 of the spreading roller 22 corresponds to the width of the diversion trough, dividing the steel slag into smaller pieces. Moreover, as the spreading roller 22 rotates, the steel slag is evenly spread into the slag pond. When spreading the steel slag, the ladle carrier 1 can move backward. The ladle carrier 1 dumps and spreads while moving backward until all the steel slag is spread. The pieces of steel slag formed by spreading through this device are smaller and can meet the subsequent process requirements without the need for traditional excavator crushing, saving a large amount of production costs.
