Description

Technical Field

[0001] The utility model provides molten iron transfer equipment, belonging to the technical field of molten iron transfer equipment. Background Art

[0002] In the process of rebar production, molten iron is one of the indispensable raw materials. During the transportation of molten iron, when molten iron is poured from one container to another, there is often a safety hazard such as splashing when the molten iron is impacted because there is often a certain distance between the outlet position of the molten iron and the bottom or liquid surface of the container.

[0003] The closer the molten iron outlet is to the liquid surface, the less splashing caused by the impact. However, as the molten iron is transported, the liquid level of the molten iron in the container to which it is transported will gradually increase. In order to prevent the molten iron level from submerging the molten iron outlet, there must be a significant height difference between the molten iron outlet and the liquid level in the container to which it is transported, so splashing is inevitable. Therefore, a molten iron transport device is needed to solve the above problem. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] according to Figure 1-5 As shown: the utility model provides a molten iron transfer equipment: it includes a support frame 1, a storage cylinder 3 is arranged above the support frame 1, a fixed cylinder 4 is fixedly connected to the bottom of the storage cylinder 3, and a transfer vehicle 7 located below the fixed cylinder 4 is arranged in the support frame 1; a slide groove 21 is opened in the fixed cylinder 4, and an adjusting cylinder 5 is slidably arranged in the slide groove 21; a fixed box 6 is arranged on one side of the support frame 1, and a lifting structure fixedly connected to the adjusting cylinder 5 is slidably arranged in the fixed box 6; a detection groove 15 connected to the outside is opened on the inner wall of the transfer vehicle 7, and a liquid level monitoring structure is arranged in the detection groove 15; a controller 2 connected to the liquid level monitoring structure circuit is arranged on the support frame 1, and the controller 2 can control the sliding of the lifting structure.

[0022] The position of the regulating cylinder 5 in the chute 21 can be changed by the lifting structure, thereby changing the distance between the molten iron outlet and the molten iron liquid level in the transfer vehicle 7, so that the regulating cylinder 5 can be as close as possible to the molten iron liquid level in the transfer vehicle 7, thereby greatly reducing the splashing phenomenon. A liquid level monitoring structure is provided in the detection tank 15, which can monitor the molten iron liquid level in the transfer vehicle 7 in real time, and automatically control the lifting and lowering of the lifting structure through the controller 2, which is very convenient.

[0023] The lifting structure includes a lifting block 10 and a connecting rod 12. The lifting block 10 is slidably arranged in the fixed box 6, and the connecting rod 12 is fixedly connected to the lifting block 10. The side wall of the fixed box 6 is provided with a limit groove 14 passing through the support frame 1, and the side wall of the fixed cylinder 4 is provided with a connecting groove 13 corresponding to the limit groove 14. The connecting rod 12 is located in the limit groove 14, and the connecting rod 12 passes through the connecting groove 13 and is fixedly connected to the adjustment cylinder 5. The fixed box 6 is provided with a motor 9, and the output shaft of the motor 9 is fixedly connected with a screw rod 11 rotatably arranged in the fixed box 6; the lifting block 10 is threadedly connected to the screw rod 11, and the motor 9 is connected to the controller 2 circuit.

[0024] The setting of the limiting groove 14 and the connecting rod 12 can limit the rotation of the lifting block 10 , thereby converting the rotation of the screw rod 11 into the movement of the lifting block 10 , and transmitting the movement to the adjusting cylinder 5 through the connecting rod 12 .

[0025] The liquid level monitoring structure includes a float 17, a protective cover 19, and a displacement sensor 18; the float 17 is slidably disposed in the detection groove 15, and the protective cover 19 is fixedly disposed on the float 17; the displacement sensor 18 is located in the protective cover 19, and the displacement sensor 18 is connected to the controller 2 circuit.

[0026] The floating block 17 and the protective cover 19 are made of slag and impurities in the process of molten iron production, can float on the molten iron, and will not be melted by the molten iron. The protective cover 19 can protect the displacement sensor 18.

[0027] The detection tank 15 is connected to the interior of the transfer vehicle 7 via a connecting hole 16 , and the connecting holes 16 are evenly spaced up and down on the transfer vehicle 7 , which can ensure that the liquid level in the detection tank 15 is synchronized with the liquid level inside the transfer vehicle 7 in real time.

[0028] A positioning hole 20 is provided on the side wall of the transfer vehicle 7, and an electric telescopic rod 8 inserted into the positioning hole 20 is provided on the side wall of the support frame 1, which can position and fix the transfer vehicle 7 to prevent the transfer vehicle 7 from being impacted by molten iron and causing unstable shaking during the transfer process.

[0029] A valve is provided at the bottom of the storage tube 3 to control the outflow of molten iron; at the same time, an insulation layer is provided on the inner wall of the storage tube 3 to prevent the molten iron from cooling and solidifying.

[0030] Principle of the utility model

[0031] like Figure 4 As shown, since the detection tank 15 is connected to the inside of the transfer vehicle 7, the liquid level in the detection tank 15 is consistent with the liquid level in the transfer vehicle 7. Due to the setting of the floating block 17, the displacement sensor 18 can float on the liquid surface. Figure 1-2 As shown, the displacement sensor 18 works and transmits the liquid level value at this time to the controller 2. The controller 2 controls the motor 9 to start according to the value of the displacement sensor 18. Figure 3 As shown, driven by the lifting structure, the regulating cylinder 5 moves downward until it is close to the molten iron level of the transfer vehicle 7. The valve at the bottom of the storage cylinder 3 is opened, so that the molten iron in the storage cylinder 3 is poured into the transfer vehicle 7 through the fixed cylinder 4 and the regulating cylinder 5; since the regulating cylinder 5 is very close to the liquid level in the transfer vehicle 7 at this time, the splashing phenomenon caused by the impact can be greatly reduced.

[0032] As the liquid level in the transfer vehicle 7 gradually increases, the float 17 can move synchronously with the liquid level in the transfer vehicle 7, so the liquid level value monitored by the liquid level monitoring structure will also increase, and the controller 2 controls the lifting structure to move synchronously, so that the regulating cylinder 5 can gradually rise, thereby ensuring that the liquid level in the transfer vehicle 7 does not submerge the regulating cylinder 5, and the regulating cylinder 5 can always maintain a suitable distance from the molten iron level in the transfer vehicle 7 to avoid splashing. When the transfer vehicle 7 is full of molten iron, close the valve at the bottom of the storage cylinder 3 to stop the transfer.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
