[0060] The preferred embodiments of the present application are described below in conjunction with the accompanying 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.

[0061] like Figure 1 and Figure 2As shown, according to the first aspect of an embodiment of the present application, a slag slow cooling field drainage system is proposed, comprising: 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 bag 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 bag 14; the pumping system 13 is arranged on the support frame 11, and the pumping system 13 includes a pumping pipe 138, and the pumping pipe 138 can extend into the slag bag 14 to extract liquid; wherein the pumping system 13 includes at least one first pumping system 13.

[0062] The slag slow cooling field drainage system provided in the embodiment of the present application includes a support frame 11, a liquid level detection device 12 and a pumping system 13. The slag bag 14 moves along the transportation path. The support frame 11 is set on the transportation path of the slag bag 14 and the liquid level detection device 12 is installed. When the slag bag 14 passes through the liquid level detection device 12, the liquid level of the liquid in the slag bag 14 is detected; when it is detected that the liquid level in the slag bag 14 exceeds a preset safety value, the pumping system 13 drives the pumping pipe 138 to extend into the slag bag 14 to extract liquid until the liquid level of the slag bag 14 is lower than the preset safety value, and the pumping system 13 drives the pumping pipe 138 to retract, so that the slag bag 14 continues to move along the transportation path. The liquid level of the slag bag 14 is automatically identified on the transportation path of the slag bag 14 by the liquid level detection device 12, and the pumping system 13 operates according to the liquid level in the slag bag 14. The slag bag 14 does not need to be turned over or moved during drainage, and there is no need for manual intervention in the slag cooling yard, which shortens the residence time of the slag bag 14 and avoids affecting the transportation rhythm of the slag bag 14; when the liquid level in the slag bag 14 does not reach the preset safety value, the slag bag 14 can continue to be transported and go 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 bag 14 and improves the drainage efficiency of the slag bag 14; at the same time, the original transportation path of the slag bag 14 is not changed, so that the slag cooling yard drainage system can be integrated into the whole process control process, which improves the safety and convenience of the transportation of the slag bag 14 and ensures the production rhythm.

[0063] It can be understood that a high-power pumping system 13 can be used directly for instantaneous pumping, thereby improving drainage efficiency, reducing the process of manually operating metallurgical gantry cranes, tank trucks, bag turning machines and other equipment to turn over bags and pour water, reducing human participation and equipment operation, and automatically starting the pumping system 13 to pump water from the slag bag 14 through the dispatching management system, thereby improving the degree of automation. Pumping by the pumping system 13 is more convenient and faster than turning over bags and pouring water, and has less impact and damage to transportation equipment, thereby improving the safety and reliability of drainage in the slag cooling field.

[0064] Furthermore, the liquid level detection device 12 and the pumping system 13 are electrically connected to the dispatching management system, and the liquid level identification of the slag bag 14, automatic retraction and extension of the pumping pipe 138, and automatic start and stop of the pumping system 13 are fully automated. The entire process can be unmanned and controlled, realizing fully automated process control of the slag bag 14 transfer.

[0065] Furthermore, the liquid level detection device 12 uses one of ultrasonic, radar or image sensors to perform contactless identification of the liquid level by ultrasonic or image recognition, quickly obtain the liquid level in the slag bag 14, and detect the residual liquid level of the slag bag 14.

[0066] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the liquid level detection device 12 is disposed above the transport path, and the slag ladle 14 passes under the liquid level detection device 12 when moving on the transport path.

[0067] In this technical solution, when the slag bag 14 is transported to the bottom of the liquid level detection device 12, the liquid level detection device 12 directly detects the liquid level in the slag bag 14, ensuring that after the liquid level detection and pumping and drainage of the slag bag 14 are completed, the slag bag 14 can pass smoothly from under the liquid level detection device 12 without changing the original transportation path of the slag bag 14, avoiding affecting the intelligent process control, and ensuring the transportation efficiency of the slag bag 14.

[0068] Furthermore, the support frame 11 is a portal 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. When the slag bag 14 moves below the liquid level detection device 12, the liquid level of the slag bag 14 is detected.

[0069] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the slag cooling field drainage system also includes: a track 15 and an electric flat car 16; the terminal end of the track 15 is connected to the slag receiving station; the electric flat car 16 is arranged on the track 15, and the electric flat car 16 can move along the track 15, and the slag bag 14 is arranged on the electric flat car 16 to transport the slag bag 14 through the electric flat car 16; wherein the slag bag 14 is an empty slag bag.

[0070] In this technical solution, the slag bag 14 is placed on the electric flat car 16, and the electric flat car 16 drives the slag bag 14 to move on the track 15 to form a transportation path; when the electric flat car 16 carries the slag bag 14 to the bottom of 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 bag 14. When the liquid level is lower than the preset safety value, the electric flat car 16 starts again and carries the slag bag 14 to the smelting workshop for slag collection; when the liquid level is higher than the preset safety value, the pumping system 13 starts, and the pumping system 13 lowers the pumping pipe 138 to After the bottom of the slag ladle 14 is reached, the liquid in the slag ladle 14 is extracted until the liquid level in the slag ladle 14 drops below a preset safety value, the pumping system 13 retracts the pumping pipe 138, and the electric flat car 16 is started again, taking the empty slag ladle to the smelting car for intermediate slag; by detecting the liquid level in the empty slag ladle on the slag receiving path of the empty slag ladle, and extracting the liquid in the empty slag ladle when the liquid level is higher than a preset safety value, the safety of the use of the empty slag ladle is improved, and there is no slag in the empty slag ladle to block the pumping pipe 138, thereby improving the pumping efficiency and effect of the slag ladle 14, and ensuring the safety of subsequent slag receiving and use of the slag ladle 14.

[0071] Furthermore, the electric flat car 16 includes a driving motor 18 and a running wheel 17. The driving motor 18 drives the running wheel 17 of the electric flat car 16 to rotate and run along the track 15. The driving motor 18 controls the start and stop action of the electric flat car 16 so that the slag bag 14 can be accurately stopped at the specified position.

[0072] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the water suction pipe 138 is a hose, and a filter device 19 is arranged on the input end of the water suction pipe 138 .

[0073] In this technical solution, the pumping pipe 138 is a hose, and the pumping system 13 drives the pumping pipe 138 to move, so that the pumping pipe 138 extends into the bottom of the slag bag 14. A filtering device 19 is provided at the input end of the pumping pipe 138 to prevent impurities deposited at the bottom of the slag bag 14 from entering the pumping pipe 138 and clogging the pumping system 13, thereby ensuring the smoothness and safety of water pumping by the pumping system 13.

[0074] Furthermore, the filter device 19 is detachably arranged on the input end of the water suction pipe 138 to facilitate replacement and cleaning of the filter device 19 .

[0075] like Figure 1As shown, in a feasible embodiment, 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 pumping 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 pumping pipe 138, so as to drive the input end of the pumping pipe 138 to move relative to the slag bag 14 through the telescopic device 133; the drain pipe 134 is connected to the output end of the pumping device 132.

[0076] In this technical solution, the pumping pipe 138 is a hose, and the telescopic end of the telescopic device 133 drives the input end of the pumping pipe 138 to rise and fall. When the telescopic device 133 is extended, it drives the pumping pipe 138 to extend into the bottom of the slag bag 14. After the pumping device 132 is started, the pumping pipe 138 extracts the liquid in the slag bag 14; when the liquid level in the slag bag 14 drops below a preset safety value, the telescopic device 133 is shortened to retract the input end of the pumping pipe 138, so as not to block the slag bag 14 from continuing to move.

[0077] like Figure 2 As shown, in a feasible embodiment, the pumping system 13 includes: a bracket 131, a winding disk 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 disk 135 is rotatably arranged on the bracket 131, and the pumping pipe 138 is wound on the winding disk 135; the driving device 136 is arranged on the bracket 131, and the driving device 136 is transmission-connected with the winding disk 135, and the driving device 136 drives the winding disk 135 to rotate and drives the input end of the pumping pipe 138 to move relative to the slag bag 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 connected to the output end of the pumping pipe 138; the drain pipe 134 is connected to the output end of the pumping device 132.

[0078] In this technical solution, the pumping pipe 138 is a hose, which is wound around the winding disk 135. The driving device 136 drives the winding disk 135 to rotate and drive the input end of the pumping pipe 138 to move, so that the input end of the pumping pipe 138 is lowered or retracted; the output shaft of the driving device 136 rotates along the first direction to drive the winding disk 135 to rotate, and the winding disk 135 moves the pumping pipe 138 down to the bottom of the slag bag 14. After starting the pumping device 132, the pumping pipe 138 extracts the liquid in the slag bag 14, and the liquid passes through the water inlet pipe 137 and the pumping device 132 and is discharged from the drain pipe 134; when the liquid level in the slag bag 14 drops below a 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 opposite direction, and the winding disk 135 retracts the input end of the pumping pipe 138 without blocking the slag bag 14 from continuing to move.

[0079] Furthermore, the driving device 136 is electrically connected to the dispatching management system, and is started according to the detection value of the liquid level detection device 12, and drives the winding disk 135 to rotate to lower the pumping pipe 138 to the bottom of the slag bag 14. After the water is pumped below the preset safety value, the driving device 136 is reversed, and the winding disk 135 retracts the pumping 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 mesh with the second gear, thereby driving the winding disk 135 to rotate, thereby realizing the lowering or retracting action of the pumping pipe 138.

[0080] 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, and then the winding disk 135 is driven by the driving motor 18 to rotate, so that the pumping pipe 138 is put into the slag bag 14 and retracted.

[0081] like Figure 2 As shown, in a feasible embodiment, the winding disk 135 includes a winding portion 1351, the water pumping pipe 138 is wound on the winding portion 1351, and a connecting pipe 1352 is provided through the winding portion 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 pumping pipe 138 through an adapter joint.

[0082] 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. The connecting pipe 1352 can rotate relative to the output end of the pumping pipe 138 to ensure that when the winding disk 135 rotates, the liquid extracted by the pumping pipe 138 can enter the water inlet pipe 137 through the connecting pipe 1352 and then be discharged from the drain pipe 134, so that the extracted liquid can be collected and reused.

[0083] Furthermore, the drain pipe 134 is connected to the water tank, so that the liquid extracted from the slag bag 14 can be discharged into the water tank through the drain pipe 134, and then recycled and processed in a centralized manner for secondary utilization.

[0084] like Figure 2 As shown, in a possible implementation manner, the axis of the connecting tube 1352 coincides with the rotation axis of the winding drum 135 .

[0085] 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 and the pumping pipe 138, and the connecting pipe 1352 and the drainage pipe 134 can be stably rotationally connected during the rotation of the winding disk 135, making the drainage structure safe and reliable.

[0086] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, the pumping system 13 further includes: a second pumping system 13, the second pumping system 13 is disposed on the support frame 11, and the second pumping system 13 and the first pumping system 13 are symmetrically arranged along the transportation path.

[0087] In this technical solution, the pumping system 13 is installed in a dual backup form, with the first pumping system 13 serving as the main pumping system 13 and the second pumping system 13 serving as the backup pumping system 13. When one of the pumping systems 13 fails, the slag bag 14 is pumped by switching to the other pumping system 13, thereby improving the reliability of pumping water from the slag bag 14, ensuring the continuity of the transportation of the slag bag 14, and preventing the transportation process of the slag bag 14 from being interrupted, thereby affecting the overall production rhythm; moreover, when the liquid level in the slag bag 14 is high and the amount of water is large, the two pumping systems 13 can be started at the same time to improve the pumping efficiency, save time, and thus reduce the impact on the transportation efficiency of the slag bag 14.

[0088] like Figure 1 and Figure 2 As shown, in a feasible implementation manner, 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.

[0089] In this technical solution, a 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 it passes through the liquid level detection device 12, whether the liquid level detection device 12 detects normally, whether the residual water in the slag bag 14 is extracted cleanly, etc. The monitoring device 20 performs a secondary confirmation remotely instead of manual confirmation work in the harsh environment of the slag cooling site, thereby improving the safety of workers' work.

[0090] Furthermore, the monitoring device 20 is electrically connected to the monitoring system.

[0091] Furthermore, the control of the pumping system 13 can be set to manual mode or automatic mode. When it is necessary to control in an automatic mode, through the host computer scheduling management system, when the slag bag 14 is in place, the detection signal sent by the liquid level detection device 12 triggers the pumping system 13 to drive the pumping pipe 138 to extend into the bottom of the slag bag 14. After pumping water to a safe liquid level, the pumping system 13 drives the pumping pipe 138 to retract, and the electric flat car 16 carries the slag bag 14 to the smelting workshop to connect the slag; the monitoring device and its system monitor the pumping work throughout the process and save the video information. When it is necessary to control in a manual mode, the host computer monitoring device 20 monitors the presence of the slag bag 14, and manually starts the pumping system 13 until the water in the slag bag 14 is completely pumped out, and the pumping system 13 drives the pumping pipe 138 to retract.

[0092] like Figure 3 As shown, according to the second aspect of the present application, a slag slow cooling field drainage method is proposed, using a slag slow cooling field drainage system as described in any one of the above technical solutions to pump water, comprising:

[0093] When the empty slag bag moves below the liquid level detection device 12, the liquid level detection device 12 detects the liquid level in the empty slag bag;

[0094] When the liquid level is higher than the preset safety value, the pumping system 13 drives the pumping pipe 138 to extend into the empty slag bag to extract liquid until the liquid level is lower than the preset safety value;

[0095] The pumping system 13 drives the pumping pipe 138 to be retracted, and the empty slag bag continues to move along the transportation path to the slag receiving station.

[0096] Through the slag slow cooling field drainage method provided by the embodiment of the present application, the empty slag bag moves along the original transportation path. When the empty slag bag moves to the bottom of the liquid level detection device 12, the liquid level detection device 12 detects the liquid level in the empty slag bag to ensure that the relative distance between the liquid level detection device 12 and the empty slag bag remains unchanged each time; when the liquid level detection device 12 detects that the liquid level in the empty slag bag exceeds the preset safety value, the pumping system 13 drives the pumping pipe 138 to extend into the bottom of the empty slag bag to pump water. After the pumping, the liquid level in the empty slag bag is lower than the preset safety value. The pumping system 13 drives the pumping pipe 138 to retract to prevent the pumping pipe 138 from hindering the movement of the empty slag bag, ensuring that the empty slag bag can continue to move along the transportation path to the slag receiving station for slag receiving. The liquid level is first determined by the liquid level detection device 12, and then the pumping system 13 is used to pump water. There is no need to flip the empty slag bag to make the empty slag bag leave the work. During the transportation of the slag bag 14, the water in the empty slag bag can be quickly discharged without interrupting the original control process or affecting the original production rhythm, thereby ensuring production efficiency.

[0097] It can be understood that after the pumping system 13 pumps water from the slag bag 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 pumping pipe 138, and the electric flat car 16 starts, taking the slag bag 14 from the pumping station to the slag receiving station to receive the slag.

[0098] In a feasible implementation, the slag slow cooling field drainage method further includes:

[0099] When the liquid level is lower than the preset safety value, the pumping system 13 does not operate, and the empty slag bag continues to move along the transportation path to the slag receiving station.

[0100] In this technical solution, when the liquid level detection device 12 monitors that the liquid level in the empty slag bag is lower than the preset safety value, the pumping system 13 does not operate, and the empty slag bag continues to move along the transportation path to the slag receiving station in the smelting workshop for slag receiving, thereby further reducing the residence time of the empty slag bag with low water volume, improving the overall transportation efficiency of the empty slag bag, and at the same time reducing unnecessary operations of the pumping system 13, thereby extending the service life of the pumping system 13.

[0101] In a feasible implementation manner, before the liquid level detection device 12 detects the liquid level in the empty slag bag, it also includes: the electric flat car 16 transports the empty slag bag to the detection and pumping station, and the electric flat car 16 stops moving to allow the empty slag bag to stay at the detection and pumping station.

[0102] In this technical solution, the electric flat car 16 can automatically move along the track 15. After the empty slag bag 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 bag, so that the relative position of the empty slag bag 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 needed, the electric flat car 16 is started again, and the electric flat car 16 continues to transport the empty slag bag to the slag receiving station; when pumping is needed to lower the liquid level, the electric flat car 16 does not operate, and the empty slag bag continues to stay at the pumping station, avoiding repeated starting and stopping of the electric flat car 16, which affects the transportation efficiency of the empty slag bag.

[0103] Furthermore, the electric flat car 16 carrying the empty slag ladle moves along the track 15 toward 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.

[0104] In a feasible implementation manner, the pumping system 13 drives the pumping pipe 138 to extend into the empty slag bag to extract liquid, and further includes:

[0105] The monitoring device 20 checks whether the pumping system 13 is normal;

[0106] When the pumping system 13 is normal, the pumping system 13 is activated to extract the liquid in the empty slag bag;

[0107] When the pumping system 13 fails, the second pumping system 13 is activated to extract the liquid in the empty slag bag.

[0108] In this technical solution, the monitoring device 20 detects the operating status of the two pumping systems 13. When the monitoring device 20 detects that the pumping system 13 is normal, the pumping system 13 is enabled to extract the liquid in the empty slag bag, and the second pumping system 13 is enabled to extract 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 production efficiency.

[0109] It is understandable that before the empty slag bag arrives at the pumping station, the monitoring device 20 is used to detect whether the first pumping system 13 and the second pumping system 13 are faulty, and then the pumping system 13 that can be used normally is enabled according to the monitoring structure of the monitoring device 20 to extract the liquid in the empty slag bag.

[0110] 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 activated at the same time to extract the liquid in the empty slag bag.

[0111] It can be understood that the slag slow cooling field drainage method provided in the embodiment of the present application is applied to the slag slow cooling field drainage system such as any of the above-mentioned 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-mentioned technical solutions.

[0112] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
