Description

Technical Field

[0001] The invention relates to the technical field of slag ladle liquid accumulation emptying devices, in particular to a slag ladle liquid accumulation emptying device. Background Art

[0002] In the smelting industry, slow cooling of slag bags is a very important process. The slag is transported to the slow cooling site by special equipment, and the slag after slow cooling is poured into the slag pool. In design, in order to ensure safety and have enough slow cooling space, the slow cooling site is far away from the slag discharge port. The empty slag bag is filled with high-temperature molten slag at the slag receiving port and transported to the slow cooling site by special equipment. After the slag is cooled, it is transported to the slag discharge port by special equipment. The slag bag after slag discharge is either directly transported to receive hot slag or placed in a designated location for standby.

[0003] At present, the existing slag bag transportation schemes are mainly "special tank truck transportation" and "gantry crane flat car transportation". The distance from the place where the bag is turned over and the water is poured (slag pool) to the slag receiving port is generally long (≥300 meters) and is in an open-air environment. In the process of transporting the slag bag to the slag receiving port, if it rains, more rainwater will accumulate in the rainy day. When the water meets the molten slag, it will explode. In order to solve the problem of liquid accumulation, the above two schemes have the following schemes for emptying the liquid in the slag bag: "Special tank truck transportation" solution: Before receiving the hot slag, the tank truck transports the slag bag to be received by the hot slag to the slag pool, turns the slag bag over, and pours out the accumulated liquid inside; "Gantry crane flat car transportation" solution: before receiving the hot slag, the gantry crane lifts the slag bag to be received by the hot slag to the slag pool, turns the slag bag over, and pours out the accumulated liquid inside; The above two solutions for emptying the liquid in the slag bag have the following shortcomings: the metallurgical gantry crane and tank car in the slag slow cooling field are important equipment in the slag slow cooling process. Using them to pour water wastes the working hours of important equipment. Based on this, a device for emptying the liquid in the slag bag is provided. Summary of the invention

The air slip ring 402 is sleeved and installed on the outside of the fixed cylinder 303 and is located above the driven gear ring 306. The stator of the air slip ring 402 is fixedly connected to the fixed cylinder 303.

[0020] In this embodiment: it should be supplemented that: the end of the liquid pipette 202 away from the liquid pipette head 203 passes through the middle end of the first electric reel 201 and is connected to the external pipeline through a rotary joint. The external pipeline is connected to the input end of the gas-liquid separator through an electric valve, and the output end of the gas-liquid separator is connected to the vacuum pump station; One end of the first air pipe 404 away from the air slip ring 402 passes through one end of the middle of the second electric reel 401 and is connected to an external pipeline through a rotary joint. The external pipeline is connected to an external air pump through an electric valve. One end of the cable 406 away from the rotating motor 312 passes through one end of the middle of the third electric drum 405 and is electrically connected to the control system and the power supply through a conductive slip ring; When the slag bag liquid emptying device is in use, its working principle is as follows: After the electric flat car 7 carries the empty slag bag 8 to the designated position below the gantry 1, a signal of arrival is transmitted to the control system of the effluent extraction device. After receiving the signal, the control system controls the driving motor 502 to work, and the driving motor 502 drives the second electric reel 401 and a linkage gear 501 to rotate, and the second electric reel 401 unwinds the first air pipe 404, and this linkage gear 501 drives two 7-shaped tooth arms 503 and the L-shaped lifting arm 302 to move downward synchronously, so that another linkage gear 501 can be driven to rotate, and another linkage gear 501 synchronously drives the first electric reel 201 and the third electric reel 405 to rotate synchronously, and the first electric reel 201 unwinds the liquid suction pipe 202, and the third electric reel 405 unwinds the cable; in this way, the liquid suction head 203 can be lowered to the bottom of the slag bag 8, and the nozzle 307 also enters the interior of the slag bag 8 and is parallel to the side wall of the slag bag 8; After the liquid suction head 203 reaches the bottom of the slag bag 8, the electric valve connected to the liquid suction pipe 202 is opened, and the negative pressure in the vacuum pump station extracts the accumulated liquid in the slag bag 8 to the gas-liquid separator through the liquid suction head 203, the liquid suction pipe 202, the electric valve, and the hard pipes connected between the various devices. The top of the gas-liquid separator is a negative pressure pipe to the vacuum pump station, and a drainage pipe is arranged at the bottom. After the liquid level in the gas-liquid separator reaches the specified height, the float controls the action of the float switch, controls the opening of the air valve, and balances the pressure inside and outside the gas-liquid separator. Under the action of gravity, the accumulated liquid is emptied through the drainage pipe at the bottom. After the accumulated liquid level drops, the float drops, the float switch is closed, the air valve is closed, and the normal vacuum process begins (it needs to be supplemented that the liquid suction pipe 202 uses a steel wire hose, which can ensure long-term use and the tube will not become deflated). In this way, the suction and discharge of the accumulated liquid inside the slag bag 8 is achieved; While the accumulated liquid inside the slag bag 8 is being discharged, the electric valve connected to the first air pipe 403 is opened, and the rotating motor 312 is started. The air pump delivers high-pressure air to the inside of the nozzle 307 through the external pipeline, the electric valve, the first air pipe 403, the air slip ring 402, and the second air pipe 404, and sprays it out through the nozzle 309 to realize the spraying operation on the side of the slag bag 8. Because the nozzle 309 is facing downward, the water droplets remaining on the side of the slag bag 8 can be blown downward; At the same time, the rotating motor 312 drives the driving gear 313 to rotate, and the driving gear 313 drives the driven gear ring 306 to rotate, so that the rotating seat 304, the inclined rail 305, the nozzle 307, the limit plate 308, and the horizontal guide rod 310 rotate in a circular manner as a whole. During the rotation of the horizontal guide rod 310, it will move up and down along the corrugated track of the corrugated annular guide rail 311, and then the nozzle 307 and the limit plate 308 will move up and down along the inclined track of the inclined rail 305, so that the water droplets can be better blown downward. With the circular operation, the omnidirectional blowing operation on the side of the slag bag 8 can be realized, so that the residual water droplets on the side of the slag bag 8 can be effectively avoided (it should be supplemented that the blowing airflow can also be hot air, which can not only blow the water droplets downward, but also dry the surface. In addition, in this process, the second air pipe 404 and the rotor of the air slip ring 402 rotate synchronously in a circular manner to ensure that the air path is unobstructed); After the accumulated liquid is drained, the inclined rail 305 is placed in the initial position (so that the inclined rail 305 will not interfere with the gantry 1 when it moves up), and then the drive motor 502 is started to synchronously reel in the first electric reel 201, the second electric reel 401, and the third electric reel 405, and the L-shaped lifting arm 302 is synchronously moved up, and then the suction assembly 2 and the blowing assembly 3 are moved out of the slag bag 8, and then the electric flat car 7 can move the slag bag 8 to the next station; It is also necessary to explain that: by adopting the vacuum suction method to extract the accumulated liquid, a gas-liquid-solid mixture can be extracted, which has strong adaptability to on-site working conditions, and the liquid suction port 203 is not equipped with a filter or a filter with a mesh size that is too large. The subsequent gas-liquid separator can separate the solids and protect the rear-end pump and other equipment. If the mesh size is too large, it will easily clog fine slag copper powder, etc.

[0021] Please refer to Figures 3 to 7 , the vertical limit rail 301 is provided with a limit rail groove for the vertical movement of the L-shaped lifting arm 302 and the 7-shaped tooth arm 503; The rotating seat 304 is provided with a hole groove for the second air pipe 404 to pass through, and the inclined rail 305 is provided with a movable groove for the nozzle 307, the limiting plate 308 and the horizontal guide rod 310 to limit and slide.

[0022] In this embodiment: the limit rail groove on the vertical limit rail 301 can provide guidance and limit for the up and down movement of the L-shaped lifting arm 302 and the 7-shaped tooth arm 503, and at the same time can ensure the meshing stability of the 7-shaped tooth arm 503 and the linkage gear 501; The movable groove can provide guidance and limitation for the movement of the nozzle 307 and the limiting plate 308. By tilting and moving the nozzle 307 downward, the ejected airflow can better blow the water droplets downward, further improving the removal efficiency of the water droplets.

[0023] Please refer to Figures 1 to 7 The inclination angle of the inclined rail 305 matches the inclination angle of the inner wall of the slag bag 8. The corrugated annular guide rail 311 is composed of a plurality of spiral segments, and the plurality of spiral segments are sequentially connected end to end along the circumferential direction to form a corrugated shape. The connection between two adjacent spiral segments is fixedly connected to the fixed cylinder 303 through a connecting column, and the connecting column at the top connection of the two spiral segments is "L" shaped. The end surface of the nozzle 307 is provided with a plurality of uniformly distributed nozzles 309 , and the height difference between the head and tail ends of a single spiral segment is greater than the height difference between two adjacent nozzles 309 .

[0024] In this embodiment: by setting an "L"-shaped connecting column, while ensuring the connection strength of the corrugated annular guide rail 311, it will not interfere with the operation of the horizontal guide rod 310. The height difference between the head and tail ends of a single spiral segment is greater than the height difference between two adjacent nozzles 309. When the nozzle 307 is tilted and moved up and down, the spraying areas of the two adjacent nozzles 309 are connected and overlapped with each other, so that the water droplets can be better blown downward to flow and converge, and finally be sucked away by the liquid suction head 203.

[0025] Please refer to Figures 1 to 5 The diameter of the rotation track of the linkage gear 501 is smaller than the diameter of the winding track of the first electric reel 201, the second electric reel 401, and the third electric reel 405 during the unwinding process.

[0026] In this embodiment: this structure allows the unwinding lengths of the first electric reel 201, the second electric reel 401 and the third electric reel 405 to be greater than the downward height of the L-shaped lifting arm 302 during the downward movement of the L-shaped lifting arm 302. That is, during this process, the first air pipe 403 and the cable 406 will not be tightened, thereby ensuring the normal use of the first air pipe 403 and the cable 406. At the same time, the liquid pipe 203 can be moved downward away from the fixed cylinder 303, that is, when the liquid pipe 203 contacts the bottom of the slag bag 8, the fixed cylinder 303 maintains a distance from the bottom of the slag bag 8, thereby ensuring the safe use of the device.

[0027] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
