[0046] The following describes the preferred embodiments of the present application with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0047] As Figure 1 and Figure 2As shown in the figure, according to the first aspect of the embodiments of the present application, a slag slow cooling field drainage system is proposed, including: a support frame 11, a liquid level detection device 12, and a pumping system 13; the support frame 11 is arranged on the transportation path of the slag ladle 14; the liquid level detection device 12 is arranged on the support frame 11, and the liquid level detection device 12 detects the liquid level in the slag ladle 14; the pumping system 13 is arranged on the support frame 11, and the pumping system 13 includes a water suction pipe 138, and the water suction pipe 138 can extend into the slag ladle 14 to extract liquid; wherein, the pumping system 13 includes at least one first pumping system 13.

[0048] The slag slow cooling field drainage system provided by the embodiments of the present application includes a support frame 11, a liquid level detection device 12, and a pumping system 13. The slag ladle 14 moves along the transportation path. By arranging the support frame 11 on the transportation path of the slag ladle 14 and installing the liquid level detection device 12, the liquid level of the liquid in the slag ladle 14 can be detected when the slag ladle 14 passes by the liquid level detection device 12; when the liquid level in the slag ladle 14 is detected to exceed the preset safety value, the pumping system 13 drives the water suction pipe 138 to extend into the slag ladle 14 to extract liquid until the liquid level of the slag ladle 14 is lower than the preset safety value, and the pumping system 13 drives the water suction pipe 138 to retract, so that the slag ladle 14 continues to move along the transportation path. Through the automatic identification of the liquid level of the slag ladle 14 by the liquid level detection device 12 on the transportation path of the slag ladle 14, the pumping system 13 operates according to the liquid level condition in the slag ladle 14. When draining water, the slag ladle 14 does not need to be flipped or moved, and there is no need for manual intervention in the slag slow cooling field, which shortens the residence time of the slag ladle 14 and avoids affecting the transfer rhythm of the slag ladle 14; when the liquid level in the slag ladle 14 does not reach the preset safety value, the slag ladle 14 can continue to be transported directly to the next process, which not only reduces the workload of the pumping system 13, but also further shortens the residence time of the slag ladle 14 and improves the drainage efficiency of the slag ladle 14; at the same time, without changing the original transportation path of the slag ladle 14, the slag slow cooling field drainage system can be integrated into the whole process control process, improving the safety and speed of the transfer of the slag ladle 14 and ensuring the production rhythm.

[0049] It can be understood that a high-power pumping system 13 can be directly used for instant water extraction, improving the drainage efficiency, reducing the process of manually operating equipment such as metallurgical gantry cranes, ladle cars, and bag turning machines for bag turning and pouring water, reducing human participation and equipment operation, automatically starting the pumping system 13 to pump water from the slag ladle 14 through the dispatching management system, improving the degree of automation. The pumping system 13 is more convenient and fast for pumping water than bag turning and pouring water, and has less impact and damage on the transportation equipment, improving the safety and reliability of slag slow cooling field drainage.

[0050] Furthermore, the liquid level detection device 12 and the pumping system 13 are electrically connected to the dispatching and management system, which fully automates the liquid level identification of the slag ladle 14, the automatic retraction and extension of the water suction pipe 138, and the automatic start and stop of the pumping system 13. The whole process can be controlled without human intervention, realizing the fully automated process control of the slag ladle 14 transfer.

[0051] Furthermore, the liquid level detection device 12 adopts one of sensors such as ultrasonic, radar or image, and non-contact identification of the liquid level is carried out by means of ultrasonic or image recognition to quickly obtain the liquid level condition in the slag ladle 14 and detect the residual liquid level of the slag ladle 14.

[0052] As Figure 1 and Figure 2 shown, in a feasible implementation manner, the liquid level detection device 12 is arranged above the transportation path, and the slag ladle 14 passes under the liquid level detection device 12 when moving on the transportation path.

[0053] In this technical solution, when the slag ladle 14 is transported under the liquid level detection device 12, the liquid level detection device 12 directly detects the liquid level in the slag ladle 14, ensuring that after the liquid level detection and pumping and draining of the slag ladle 14 are completed, the slag ladle 14 can pass under the liquid level detection device 12 smoothly, without changing the original transportation path of the slag ladle 14, avoiding affecting the intelligent process control, and ensuring the transfer efficiency of the slag ladle 14.

[0054] Furthermore, the support frame 11 is a gantry structure frame, the support frame 11 is arranged across the transportation path, and the liquid level detection device 12 is installed on the top of the support frame 11 to detect the liquid level condition of the slag ladle 14 when the slag ladle 14 moves under the liquid level detection device 12.

[0055] As Figure 1 and Figure 2 shown, in a feasible implementation manner, the slag slow cooling field drainage system further includes: a track 15 and an electric flat car 16; the termination end of the track 15 is connected to the slag receiving station; the electric flat car 16 is arranged on the track 15, the electric flat car 16 can travel along the track 15, and the slag ladle 14 is arranged on the electric flat car 16 to transport the slag ladle 14 through the electric flat car 16; wherein, the slag ladle 14 is an empty slag ladle.

[0056] In this technical solution, the slag ladle 14 is placed on the electric flat car 16, and the electric flat car 16 drives the slag ladle 14 to travel on the track 15 to form a transportation path. When the electric flat car 16 carries the slag ladle 14 under the liquid level detection device 12, the electric flat car 16 stops moving, and the liquid level detection device 12 detects the liquid level in the slag ladle 14. When the liquid level is lower than the preset safety value, the electric flat car 16 starts again and carries the slag ladle 14 to the smelting workshop to receive slag. When the liquid level is higher than the preset safety value, the pumping system 13 starts. After the water suction pipe 138 of the pumping system 13 is lowered to the bottom of the slag ladle 14, the liquid in the slag ladle 14 is pumped until the liquid level in the slag ladle 14 drops below the preset safety value. The pumping system 13 retracts the water suction pipe 138, and the electric flat car 16 starts again and takes the empty slag ladle to the smelting workshop to receive slag. By detecting the liquid level in the empty slag ladle on the slag receiving path of the empty slag ladle and pumping the liquid in the empty slag ladle when the liquid level is higher than the preset safety value, the safety of using the empty slag ladle is improved, and there is no slag in the empty slag ladle to block the water suction pipe 138, which improves the pumping efficiency and effect of the slag ladle 14 and ensures the safety of subsequent slag receiving and use of the slag ladle 14.

[0057] Further, the electric flat car 16 includes a drive motor 18 and walking wheels 17. The drive motor 18 drives the walking wheels 17 of the electric flat car 16 to rotate and travel along the track 15, and the drive motor 18 controls the start and stop actions of the electric flat car 16, so that the slag ladle 14 can accurately stop at the specified position.

[0058] As Figure 1 and Figure 2 shown, in a feasible implementation manner, the water suction pipe 138 is a flexible pipe, and a filtering device 19 is provided at the input end of the water suction pipe 138.

[0059] In this technical solution, the water suction pipe 138 is a flexible pipe, and the pumping system 13 drives the water suction pipe 138 to move, so that the water suction pipe 138 extends into the bottom of the slag ladle 14. By providing a filtering device 19 at the input end of the water suction pipe 138, impurities deposited at the bottom of the slag ladle 14 are prevented from entering the water suction pipe 138 and blocking the pumping system 13, ensuring the smoothness and safety of the pumping system 13 for pumping water.

[0060] Further, the filtering device 19 is detachably provided at the input end of the water suction pipe 138 for easy replacement and cleaning of the filtering device 19.

[0061] As Figure 1As shown, in a feasible implementation, the pumping system 13 includes: a bracket 131, a pumping device 132, a telescopic device 133, and a drain pipe 134; the bracket 131 is arranged on the support frame 11; the pumping device 132 is arranged on the bracket 131, and the input end of the pumping device 132 is connected to the output end of the suction pipe 138; the fixed end of the telescopic device 133 is arranged on the bracket 131, and the telescopic end of the telescopic device 133 is connected to the input end of the suction pipe 138 to drive the input end of the suction pipe 138 to move relative to the slag ladle 14 through the telescopic device 133; the drain pipe 134 is connected to the output end of the pumping device 132.

[0062] In this technical solution, the suction pipe 138 is a flexible pipe. The telescopic end of the telescopic device 133 drives the input end of the suction pipe 138 to move up and down. When the telescopic device 133 extends, it drives the suction pipe 138 to extend into the bottom of the slag ladle 14. After the pumping device 132 is started, the suction pipe 138 extracts the liquid in the slag ladle 14; when the liquid level in the slag ladle 14 drops below a preset safety value, the telescopic device 133 shortens to retract the input end of the suction pipe 138 without blocking the continuous movement of the slag ladle 14.

[0063] As Figure 2 As shown, in a feasible implementation, the pumping system 13 includes: a bracket 131, a winding disc 135, a driving device 136, a pumping device 132, a water inlet pipe 137, and a drain pipe 134; the bracket 131 is arranged on the support frame 11; the winding disc 135 is rotatably arranged on the bracket 131, and the suction pipe 138 is wound around the winding disc 135; the driving device 136 is arranged on the bracket 131, the driving device 136 is in transmission connection with the winding disc 135, and the driving device 136 drives the winding disc 135 to rotate to drive the input end of the suction pipe 138 to move relative to the slag ladle 14; the pumping device 132 is arranged on the bracket 131; one end of the water inlet pipe 137 is connected to the input end of the pumping device 132, and the other end of the water inlet pipe 137 is communicated with the output end of the suction pipe 138; the drain pipe 134 is connected to the output end of the pumping device 132.

[0064] In this technical solution, the water suction pipe 138 is a flexible pipe. The water suction pipe 138 is wound around the winding disk 135. The driving device 136 drives the winding disk 135 to rotate, driving the movement of the input end of the water suction pipe 138, and lowering or retracting the input end of the water suction pipe 138; the output shaft of the driving device 136 rotates in the first direction to drive the winding disk 135 to rotate. The winding disk 135 lowers the water suction pipe 138 to the bottom of the slag packet 14. After starting the water pumping device 132, the water suction pipe 138 extracts the liquid in the slag packet 14. The liquid passes through the water inlet pipe 137 and the water pumping device 132 and then is discharged from the drain pipe 134; when the liquid level in the slag packet 14 drops below the preset safety value, the output shaft of the driving device 136 rotates in the opposite direction of the first direction to drive the winding disk 135 to rotate in the reverse direction. The winding disk 135 retracts the input end of the water suction pipe 138 without blocking the continued movement of the slag packet 14.

[0065] Further, the driving device 136 is electrically connected to the scheduling management system and is started according to the detection value of the liquid level detection device 12. It drives the winding disk 135 to rotate to lower the water suction pipe 138 to the bottom of the slag packet 14. After pumping water below the preset safety value, the driving device 136 rotates in the reverse direction, and the winding disk 135 retracts the water suction pipe 138. In some examples, a first gear is provided on the output shaft of the driving device 136, and a second gear is provided on the winding disk 135. The driving device 136 drives the first gear to rotate and engage with the second gear, thereby driving the winding disk 135 to rotate, and further realizing the lowering or retracting action of the water suction pipe 138.

[0066] It can be understood that the PLC and the frequency converter cooperate to realize the forward and reverse rotation and speed control of the driving motor 18. Then, the driving motor 18 drives the winding disk 135 to rotate, realizing the placement and retraction of the water suction pipe 138 into and from the slag packet 14.

[0067] As Figure 2 shown, in a feasible implementation manner, the winding disk 135 includes a coiling part 1351. The water suction pipe 138 is coiled around the coiling part 1351. A connecting pipe 1352 is provided through the coiling part 1351. One end of the connecting pipe 1352 is rotatably connected to the water inlet pipe 137 through an adapter joint, and the other end of the connecting pipe 1352 is rotatably connected to the output end of the water suction pipe 138 through an adapter joint.

[0068] In this technical solution, the connecting pipe 1352 rotates synchronously with the winding disk 135. The connecting pipe 1352 can rotate relative to the drain pipe 134 and can rotate relative to the output end of the water suction pipe 138 to ensure that when the winding disk 135 rotates, the liquid extracted by the water suction pipe 138 can enter the water inlet pipe 137 through the connecting pipe 1352 and be centrally discharged from the drain pipe 134, facilitating the collection and reuse of the extracted liquid.

[0069] Further, the drain pipe 134 is connected to the water tank, so as to discharge the liquid extracted from the slag bag 14 into the water tank through the drain pipe 134, and after centralized recovery treatment, it can be reused.

[0070] As Figure 2 shown, in a feasible implementation, the axis of the connecting pipe 1352 coincides with the rotation axis of the winding disk 135.

[0071] In this technical solution, the axis of the connecting pipe 1352 coincides with the rotation axis of the winding disk 135, ensuring that the connecting pipe 1352 does not rotate eccentrically, so as to ensure that the connecting pipe 1352 can be stably rotationally connected to the water extraction pipe 138 and the connecting pipe 1352 can be stably rotationally connected to the drain pipe 134 during the rotation of the winding disk 135, making the drainage structure safe and reliable.

[0072] As Figure 1 and Figure 2 shown, in a feasible implementation, the pumping system 13 further includes: a second pumping system 13, the second pumping system 13 is arranged on the support frame 11, and the second pumping system 13 and the first pumping system 13 are symmetrically arranged along the transportation path.

[0073] In this technical solution, the pumping system 13 is installed in a dual-backup form. The first pumping system 13 serves as the main pumping system 13, and the second pumping system 13 serves as the standby pumping system 13. When one of the pumping systems 13 fails, the other pumping system 13 is switched to pump water from the slag bag 14, improving the reliability of pumping water from the slag bag 14, ensuring the continuity of the transfer of the slag bag 14, preventing the transfer process of the slag bag 14 from being interrupted, and affecting the overall production rhythm; moreover, when the liquid level in the slag bag 14 is relatively high and the water volume is large, the two pumping systems 13 can be started simultaneously to improve the pumping efficiency, save time, and thus reduce the impact on the transfer efficiency of the slag bag 14.

[0074] As Figure 1 and Figure 2 shown, in a feasible implementation, the slag slow-cooling field drainage system further includes: a monitoring device 20, and the monitoring device 20 is arranged on the support frame 11.

[0075] In this technical solution, the monitoring device 20 is installed on the support frame 11 to monitor the working condition of the pumping system 13, the state of the slag bag 14 when passing through the liquid level detection device 12, whether the liquid level detection device 12 is detected normally, whether the residual water in the slag bag 14 is pumped out completely, etc. The remote secondary confirmation through the monitoring device 20 replaces the manual confirmation work in the harsh environment at the slag slow-cooling field site, improving the safety of the workers' work.

[0076] Further, the monitoring device 20 is electrically connected to the monitoring system.

[0077] Further, the control of the pumping system 13 can be set to manual mode or automatic mode. When automatic control is required, through the host computer dispatching and management system, after the slag ladle 14 arrives, the detection signal sent by the liquid level detection device 12 triggers the pumping system 13 to drive the suction pipe 138 to extend to the bottom of the slag ladle 14. After pumping to the safe liquid level, the pumping system 13 drives the suction pipe 138 to retract, and the electric flat car 16 carries the slag ladle 14 to run towards the smelting workshop to receive slag; the monitoring device and its system monitor the pumping operation throughout the process and save the video information. When manual control is required, the arrival situation of the slag ladle 14 is monitored through the host computer monitoring device 20, and the pumping system 13 is manually started until the water in the slag ladle 14 is completely pumped out, and then the pumping system 13 drives the suction pipe 138 to retract.

[0078] As Figure 3 shown, according to the second aspect of the present application, a method for draining water from the slag slow cooling field is proposed. Using the slag slow cooling field drainage system according to any one of the above technical solutions for pumping water, it includes:

[0079] When the empty slag ladle moves below the liquid level detection device 12, the liquid level detection device 12 detects the liquid level in the empty slag ladle;

[0080] When the liquid level is higher than the preset safety value, the pumping system 13 drives the suction pipe 138 to extend into the empty slag ladle to extract the liquid until the liquid level is lower than the preset safety value;

[0081] The pumping system 13 drives the suction pipe 138 to retract, and the empty slag ladle continues to move along the transportation path to the slag receiving station.

[0082] Through the method for draining water from the slag slow cooling field provided by the embodiments of the present application, the empty slag ladle moves along the original transportation path. When the empty slag ladle moves below the liquid level detection device 12, the liquid level detection device 12 detects the liquid level in the empty slag ladle to ensure that the relative distance between the liquid level detection device 12 and the empty slag ladle remains unchanged each time; when the liquid level detection device 12 detects that the liquid level in the empty slag ladle exceeds the preset safety value, the pumping system 13 drives the suction pipe 138 to extend to the bottom of the empty slag ladle for pumping water. After pumping, the liquid level in the empty slag ladle is lower than the preset safety value, and the pumping system 13 drives the suction pipe 138 to retract to prevent the suction pipe 138 from obstructing the movement of the empty slag ladle and ensure that the empty slag ladle can continue to move along the transportation path to the slag receiving station for slag receiving. First, the liquid level is judged by the liquid level detection device 12, and then the pumping system 13 pumps water. There is no need to flip the empty slag ladle to make it leave the work. During the transfer of the slag ladle 14, the water in the empty slag ladle can be quickly discharged, without interrupting the original control process and without affecting the original production rhythm, ensuring production efficiency.

[0083] It is understandable that after the pumping system 13 pumps water from the slag ladle 14, the liquid level detection device 12 detects in real time whether the liquid level drops below the preset safety value. When the liquid level detection device 12 detects that the liquid level is lower than the preset safety value, the pumping system 13 retracts the water suction pipe 138, and the electric flat car 16 starts to move the slag ladle 14 with the strength from the pumping station to the slag receiving station to receive slag.

[0084] In a feasible implementation manner, the slag slow cooling field drainage method further includes:

[0085] When the liquid level is lower than the preset safety value, the pumping system 13 does not operate, and the empty slag ladle continues to move along the transport path to the slag receiving station.

[0086] In this technical solution, when the liquid level detection device 12 monitors that the liquid level in the empty slag ladle is lower than the preset safety value, the pumping system 13 does not operate, and the empty slag ladle continues to move along the transport path to the slag receiving station in the smelting workshop to receive slag, further reducing the residence time of the empty slag ladle with low water volume, improving the overall transfer efficiency of the empty slag ladle, and at the same time reducing unnecessary operations of the pumping system 13 and prolonging the service life of the pumping system 13.

[0087] In a feasible implementation manner, before the liquid level detection device 12 detects the liquid level in the empty slag ladle, it further includes: the electric flat car 16 transports the empty slag ladle to the detection and pumping station, and the electric flat car 16 stops operating, so that the empty slag ladle stays at the detection and pumping station.

[0088] In this technical solution, the electric flat car 16 can automatically travel along the track 15. After the empty slag ladle is transported to the pumping station by the electric flat car 16, the liquid level detection device 12 detects the liquid level in the empty slag ladle, so that the relative position between the empty slag ladle and the liquid level detection device 12 remains unchanged each time, which is beneficial to improving the accuracy of the liquid level detection result; the pumping system 13 operates according to the detection result. When pumping is not required, the electric flat car 16 starts again, and the electric flat car 16 continues to transport the empty slag ladle to the slag receiving station; when pumping is required to lower the liquid level, the electric flat car 16 does not operate, and the empty slag ladle continues to stay at the pumping station, avoiding repeated start and stop of the electric flat car 16 and affecting the transfer efficiency of the empty slag ladle.

[0089] Further, the electric flat car 16 carries the empty slag ladle and moves along the track 15 towards the smelting workshop. After moving to the slag receiving station, the electric flat car 16 stops, and the empty slag ladle stays at the slag receiving station to receive slag.

[0090] In a feasible implementation manner, when the pumping system 13 drives the water suction pipe 138 to extend into the empty slag ladle to extract liquid, it further includes:

[0091] The monitoring device 20 checks whether the pumping system 13 is normal;

[0092] When the pumping system 13 is normal, the pumping system 13 is enabled to extract the liquid in the empty slag ladle;

[0093] When the pumping system 13 fails, the second pumping system 13 is enabled to pump the liquid in the empty slag bag.

[0094] In this technical solution, the monitoring device 20 detects the operating states of the two pumping systems 13. When the monitoring device 20 monitors that the pumping system 13 is normal, the pumping system 13 is enabled to pump the liquid in the empty slag bag, and the second pumping system 13 is enabled to pump the liquid in the empty slag bag, so as to avoid affecting the transfer efficiency of the empty slag bag due to the failure of the pumping system 13 and interrupting the automated production process control, thereby ensuring the production efficiency.

[0095] It can be understood that before the empty slag bag reaches the pumping station, the monitoring device 20 first detects whether the first pumping system 13 and the second pumping system 13 are faulty, and then enables the available pumping system 13 to pump the liquid in the empty slag bag according to the monitoring result of the monitoring device 20.

[0096] It can be understood that when the first pumping system 13 is normal and the second pumping system 13 is normal, and when the liquid level is much higher than the preset safety value, the first pumping system 13 and the second pumping system 13 are enabled simultaneously to pump the liquid in the empty slag bag.

[0097] It can be understood that the slag slow cooling field drainage method provided by the embodiments of the present application, because it is applied to the slag slow cooling field drainage system of any of the above technical solutions, so the slag slow cooling field drainage method has all the beneficial effects of the slag slow cooling field drainage system of the above technical solutions.

[0098] It is easy for those skilled in the art to understand that on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.
