[0031] The utility model provides a device for treating converter waste liquid and waste slag, referring to Figures 1 to 3 A device for treating converter waste liquid and waste slag includes a workbench 1, on which two second support plates 12 arranged at intervals are fixed, and a converter body 2 is rotatably connected between the two second support plates 12; a first support plate 11 is fixed on the plate surface of one of the second support plates 12, and a driving mechanism for driving the converter body 2 to rotate is arranged on the first support plate 11.

[0032] A guide shell 3 is fixed under the workbench 1. Specifically, a unloading window 14 connected to the guide shell 3 is opened on the surface of the workbench 1. A spiral feeding structure 31 is rotatably arranged in the guide shell 3. A first servo motor 32 for driving the spiral feeding structure 31 to rotate is fixed at one end of the guide shell 3.

[0033] A discharge hopper 5 is provided at one end of the guide shell 3 away from the first servo motor 32. The discharge hopper 5 is tilted downward from the feed end to the discharge end, and the discharge end of the discharge hopper 5 is connected to a waste treatment mechanism 6. By providing a discharge window 14, it is convenient to pour the waste liquid and waste residue in the converter body 2 into the guide shell 3. The first servo motor 32 drives the spiral feeding structure 31 to rotate, so that the waste liquid and waste residue can be transported from the guide shell 3 to the waste treatment mechanism 6 through the discharge hopper 5. After the waste liquid and waste residue are processed by the waste treatment mechanism 6, the waste residue and waste liquid are discharged into the subsequent operation process automatically without the need for human transportation. This application improves work efficiency, greatly saves the physical strength of the staff, and the transportation process is also safer.

[0034] The steering drive mechanism 13 includes a second servo motor 131, a first gear 132 and a second gear 133. The second servo motor 131 is fixedly connected to the upper end of the first support plate 11, the first gear 132 is fixedly connected to the rotating end of the second servo motor 131, the second gear 133 is fixedly connected to the rotating end of the converter body 2, and the first gear 132 and the second gear 133 are meshed with each other. The operation of the second servo motor 131 can drive the first gear 132 to rotate, and the rotation of the first gear 132 can drive the second gear 133 to rotate, thereby driving the converter body 2 to rotate.

[0035] An electric telescopic rod 134 is fixed on the surface of the second support plate 12, and a limit block 135 that can mesh with the second gear 133 is fixedly connected to the lower end of the electric telescopic rod 134. When the converter body 2 stops working, it may rotate automatically due to a fault, thereby causing an accident. To avoid accidents, the electric telescopic rod 134 and the limit block 135 are provided, and the limit block 135 can be driven to move downward by extending the electric telescopic rod 134. The limit block 135 and the second gear 133 are meshed with each other to fix the second gear 133, thereby effectively reducing accidents caused by the converter body 2 rotating automatically due to a fault.

[0036] The waste treatment mechanism 6 includes a treatment box 61 and a stirring assembly 62 rotatably arranged in the treatment box 61. A driving motor for driving the stirring assembly 62 to rotate is arranged on the top of the treatment box 61. A plurality of slag discharge ports 611 are opened on the bottom wall of the treatment box 61. The waste slag discharged from the discharge hopper 5 enters the treatment box 61 for treatment and is then discharged through the slag discharge ports 611.

[0037] Specifically, a cooling pipe 4 is arranged around the outer wall of the guide shell 3, and the water inlet end of the cooling pipe 4 is connected to a pump body, and the water outlet end of the cooling pipe 4 is connected to the top wall of the treatment box 61. The pump body can pump cold water from the outside into the cooling pipe 4, and the water is discharged into the treatment box 61 after flowing through the cooling pipe 4. The cooling pipe 4 can be used to cool the waste liquid and waste residue in the guide shell 3. After the cooling water is discharged into the treatment box 61, the stirring assembly 62 is driven to rotate so that the waste residue and waste liquid can be evenly stirred with the cooling water, thereby cooling the waste residue and waste liquid again, which is convenient for the subsequent harmless treatment of the waste residue and waste liquid.

[0038] Furthermore, a plurality of spray nozzles 41 are arranged on the top wall of the processing box 61, and the water outlet end of the cooling pipe 4 is simultaneously connected to the plurality of spray nozzles 41, so that cooling water can be sprayed through the plurality of spray nozzles 41, thereby achieving a more uniform dust reduction and cooling effect in the processing box 61.

[0039] The stirring assembly 62 includes a central axis 621 and a plurality of stirring edges 622 arranged around the central axis 621. The stirring edges 622 are arranged in multiple layers, and the plurality of stirring edges 622 in each layer are arranged around the central axis 621 at intervals. The stirring edges 622 of the bottom layer are in contact with the bottom wall of the processing box 61, so that the stirring edges 622 of the bottom layer can drive the waste residue in the processing box 61 to the slag discharge port 611 and discharge it. In addition, the thickness of each stirring edge 622 gradually becomes thinner from the middle to both ends along the height direction of the processing box 61, which makes it difficult for waste to accumulate on the stirring edges 622 on the one hand, and on the other hand enables the stirring edges 622 of the bottom layer to better push the waste to be discharged from the slag discharge port 611.

[0040] A plurality of slag discharge ports 611 are arranged at intervals around the bottom wall of the treatment box 61. Each slag discharge port 611 is arc-shaped, and each slag discharge port 611 is at a different distance from the central axis 621. At the same time, the end surface of the free end of the stirring edge is in contact with the inner wall of the treatment box. On the one hand, the waste can be discharged more evenly from the bottom wall of the treatment box 61, reducing the large amount of waste discharged from the same area at the bottom of the treatment box 61, which causes waste accumulation, and provides convenience for the waste to be transported away in batches; on the other hand, the waste in each area of ​​the treatment box 61 can be discharged from the slag discharge port 611.

[0041] An air suction fan 7 is also provided on the top of the processing box 61. The air inlet of the air suction fan is located inside the processing box 61, and the air outlet of the air suction fan is located outside the processing box 61. The air outlet of the air suction fan 7 can be connected to the subsequent gas harmless treatment equipment. By setting the air suction fan 7, the harmful gas generated in the process of cooling the waste residue and waste liquid can be exhausted, thereby reducing the pollution of the working environment caused by direct emission of harmful gases.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
