Description

Technical Field

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

[0002] In the smelting industry, slow cooling of slag ladles is a crucial process. Slag is transported to the slow cooling area via specialized equipment, where it is dumped into the slag pool. To ensure safety and sufficient space for slow cooling, the slow cooling area is located farther from the slag discharge port. Empty slag ladles are filled with high-temperature molten slag at the slag receiving port and transported to the slow cooling area via specialized equipment. Once the slag has cooled, it is transported to the slag discharge port via specialized equipment. The slag ladles are then either transported directly to a hot slag receiving port or stored in a designated location for future use.

[0003] At present, the existing slag bag transportation solutions are mainly "dedicated 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, a lot of rainwater will accumulate. In rainy days, water will explode when it encounters molten slag. To solve the problem of liquid accumulation, the above two solutions have the following solutions for emptying the liquid in the slag bag:

[0004] "Specialized tank truck transportation" solution: Before receiving the hot slag, the tank truck will transport the slag bag to the slag pool, turn the slag bag over, and pour out the accumulated liquid inside;

[0005] "Gantry crane flat car transportation" solution: Before receiving the hot slag, the gantry crane lifts the slag bag to be received to the slag pool, turns the slag bag over, and pours out the accumulated liquid inside;

[0006] The above two solutions for emptying the liquid accumulated in the slag bag have the following shortcomings: the metallurgical gantry crane and tank car in the slag slow cooling yard are important equipment in the slag slow cooling process. Using them to pour water wastes the operating hours of important equipment. Based on this, a slag bag liquid emptying device is provided. Summary of the Invention

[0007] The purpose of the present invention is to provide a device for emptying liquid accumulated in a slag ladle in order to solve the above-mentioned problems.

The cable is wound around the outside of the third electric drum and the bottom end of the cable is electrically connected to the terminal of the rotating motor, which is used to provide circuit connection between the rotating motor and the external power supply.

The connection between two adjacent spiral segments is fixedly connected to the fixed cylinder through a connecting column, and the connecting column at the top connection of the two spiral segments is "L"-shaped;

[0034] The end surface of the nozzle is provided with a plurality of evenly distributed nozzles, 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.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

In addition, while the nozzle is performing a circular rotation and blowing, the horizontal guide rod will move the nozzle along the trajectory of the corrugated annular guide rail, forcing the nozzle to move up and down at an angle, thereby realizing the nozzle's all-round blowing operation on the side of the slag ladle, which can effectively avoid the situation of residual water droplets on the side of the slag ladle and improve the drainage effect. Compared with the traditional operation of pouring out the accumulated liquid by flipping the slag ladle, the device structure is simpler and the overall operation is more convenient, achieving the purpose of freeing up the working hours of metallurgical gantry cranes and tank truck equipment.

When the nozzle 307, the limit plate 308, the nozzle 309, and the horizontal guide rod 310 rotate in a circular motion, they move up and down along the upper surface of the corrugated annular guide rail 311.

[0060] The suction assembly 2 includes a first motorized reel 201, a liquid suction tube 202, and a liquid suction head 203;

[0061] The first motorized reel 201 is mounted on the top of the gantry 1 through a bracket and is distributed on one side of the front end of the vertical limit rail 301. The pipette 202 is wound around the outside of the first motorized reel 201 and the bottom end of the pipette 202 passes through the fixed cylinder 303 to the bottom of the fixed cylinder 303. The pipette head 203 is fixed to the bottom end of the pipette 202.

[0062] The first motorized reel 201 is used to realize the winding and unwinding operation of the liquid pipe 202, and the liquid pipette 203 is moved downward to the interior of the slag ladle 8 to perform a suction operation on the accumulated liquid inside the slag ladle 8;

[0064] The second motorized reel 401 passes through the top of the support gantry 1 and is symmetrically distributed with the first motorized reel 201 along the horizontal direction with the vertical limit rail 301 as the center. 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.

[0065] The first air pipe 403 is wound around the outside of the second motorized reel 401, and the bottom end of the first air pipe 403 is connected to the inlet on the stator of the air slip ring 402. One end of the second air pipe 404 is connected to the air outlet at the bottom of the rotor of the air slip ring 402. The other end of the second air pipe 404 passes through the inside of the driven gear ring 306, the upper and lower ends of the rotating seat 304, and both ends of the limit plate 308 in sequence, and is connected to the nozzle 307. The channel formed by the first air pipe 403, the air slip ring 402, and the second air pipe 404 is used to provide an air path for the nozzle 307 to communicate with the external air pump.

[0066] The third motorized drum 405 passes through the top of the support gantry 1 and is distributed on one side of the rear end of the vertical limit rail 301. The cable 406 is wound around the outside of the third motorized drum 405, and the bottom end of the cable 406 is electrically connected to the terminal of the rotating motor 312, so as to provide an electrical connection between the rotating motor 312 and an external power source.

[0067] The driving assembly 5 includes a linkage gear 501, a driving motor 502, and a 7-shaped gear arm 503;

[0068] The third motorized reel 405 and the first motorized reel 201 are symmetrically distributed along the horizontal longitudinal direction with the vertical limiting rail 301 as the center, and the rotating shafts of the third motorized reel 405 and the first motorized reel 201 are connected and fixed to each other, and the linkage gear 501 is respectively fixed to the rotating shaft of the second motorized reel 401 and the outer sides of the rotating shafts of the first motorized reel 201 and the third motorized reel 405;

[0069] The 7-shaped gear arms 503 are symmetrically fixed to the top two sides of the L-shaped lifting arm 302 and are slidingly connected to the two sides of the vertical limit rail 301. The two 7-shaped gear arms 503 are respectively engaged with two linkage gears 501. The linkage gears 501 are fixed to the top of the gantry 1 through a bracket, and the output end of the linkage gear 501 is fixedly connected to the rotating shaft of the second motorized reel 401.

[0070] The linkage gear 501 is used to provide power for the winding and unwinding operations of the second motorized reel 401 , the third motorized reel 405 and the first motorized reel 201 , and also provides power for the lifting and lowering of the L-shaped lifting arm 302 .

[0071] In this embodiment, it should be noted that the end of the pipette 202 away from the pipette head 203 passes through the middle end of the first motorized 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.

[0072] 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 motorized reel 401 and is connected to an external pipe through a rotary joint. The external pipe is connected to an external air pump through an electric valve.

[0073] One end of the cable 406 away from the rotating motor 312 passes through one end of the middle portion of the third motorized reel 405 and is electrically connected to the control system and the power supply through a conductive slip ring;

[0074] The working principle of this slag bag liquid emptying device when in use is as follows:

[0075] After the electric flat car 7 carries the empty slag bag 8 to the designated position below the gantry 1, it transmits a position signal to the control system of the effusion 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. The second electric reel 401 unwinds the first air pipe 404, and this linkage gear 501 drives two 7-shaped gear arms 503 and the L-shaped lifting arm 302 to move downward synchronously, thereby driving another linkage gear 501 to rotate, and another linkage gear 501 synchronously drives the first electric reel 201 and the third electric reel 405 to rotate synchronously, the first electric reel 201 unwinds the liquid 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;

[0076] 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. The negative pressure in the vacuum pump station draws the accumulated liquid in the slag bag 8 through the liquid suction head 203, the liquid suction pipe 202, the electric valve, and the hard pipes connected between the various devices to the gas-liquid separator. 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. When the liquid level in the gas-liquid separator reaches a specified height, the float controls the action of the float switch, which controls the opening of the air valve to balance the pressure inside and outside the gas-liquid separator. Under the action of gravity, the accumulated liquid is drained through the drainage pipe at the bottom. When the accumulated liquid level drops, the float drops, the float switch closes, the air valve closes, and the normal vacuum process begins (it should be noted 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 liquid accumulated in the slag bag 8 is sucked out.

[0077] While the accumulated liquid inside the slag ladle 8 is being drained, the electric valve connected to the first air pipe 403 is opened, and the rotary motor 312 is started. The air pump delivers high-pressure air through the external pipeline, the electric valve, the first air pipe 403, the air slip ring 402, and the second air pipe 404 to the interior of the nozzle 307, and then sprays it through the nozzle 309 to achieve the blowing operation on the side of the slag ladle 8. Because the nozzle 309 is facing downward, it can blow the water droplets remaining on the side of the slag ladle 8 downward.

[0078] 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, thereby causing the rotating seat 304, the inclined rail 305, the nozzle 307, the limit plate 308, and the horizontal guide rod 310 to 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, thereby causing the nozzle 307 and the limit plate 308 to move up and down along the inclined track of the inclined rail 305, so as to better blow the water droplets downward. In conjunction with the circular movement, an all-round blowing operation can be achieved on the side of the slag bag 8, thereby effectively avoiding the situation where residual water droplets appear on the side of the slag bag 8 (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, during this process, the second air pipe 404 rotates synchronously with the rotor of the air slip ring 402 to ensure that the air path is unobstructed);

[0079] After the accumulated liquid is drained, the inclined rail 305 is placed in its initial position (so that it does not interfere with the gantry 1 when moving upward), and then the drive motor 502 is started to synchronously reel in the first, second, and third motorized reels 201, 401, and 405, and the L-shaped lifting arm 302 is synchronously moved upward, thereby removing the suction assembly 2 and the blowing assembly 3 from the slag bag 8. The electric flat car 7 can then move the slag bag 8 to the next workstation.

[0080] It should also be noted that: by adopting the vacuum suction method to extract the accumulated liquid, the gas-liquid-solid mixture can be extracted, which has strong adaptability to the on-site working conditions, and the liquid suction port 203 is not equipped with a filter or a filter with too large a mesh size. 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.

[0081] 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;

[0082] 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.

[0083] In this embodiment, the limiting rail groove on the vertical limiting rail 301 can provide guidance and limit for the up and down movement of the L-shaped lifting arm 302 and the 7-shaped gear arm 503, while ensuring the meshing stability of the 7-shaped gear arm 503 and the linkage gear 501;

[0084] 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 water droplet removal efficiency.

[0085] 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 ladle 8. The corrugated annular guide rail 311 is composed of multiple spiral segments, and the multiple 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;

[0086] The end surface of the nozzle 307 is provided with a plurality of evenly 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 .

[0087] 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. By making the height difference between the head and tail ends of a single spiral segment greater than the height difference between the 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.

[0088] 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 motorized reel 201 , the second motorized reel 401 , and the third motorized reel 405 during the unwinding process.

[0089] In this embodiment: through this structure, during the downward movement of the L-shaped lifting arm 302, the unwinding length of the first electric reel 201, the second electric reel 401, and the third electric reel 405 can be greater than the downward movement height 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 suction head 203 can move downward away from the fixed cylinder 303, that is, when the liquid suction head 203 contacts the bottom of the slag bag 8, the fixed cylinder 303 maintains a certain distance from the bottom of the slag bag 8, thereby ensuring the safe use of the device.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
