Technical Field
[0001] The invention relates to the technical field of slag scoop machines, in particular to a movable slag scoop machine dust removal device. Background Art
[0002] During the process of blast furnace molten iron tapping, the molten iron slag remover is used to remove slag and impurities in the molten iron to prevent slag from bubbling and improve the quality of the molten iron. Before the molten iron enters the converter or electric furnace for steelmaking, the slag remover can further remove the residual slag in the molten iron to ensure the smooth progress of the steelmaking process. When the slag remover is in use, a certain amount of metal dust will be generated. If the metal dust is not treated, the metal dust will affect the working environment.

When the hose moves, the circular sleeve can be driven to move synchronously, so that the circular sleeve can drive the buckle and the slider to move synchronously. The slider slides on the surface of the slide rod to fix the movement trajectory of the circular sleeve. When the circular sleeve moves, the spring can be compressed or stretched by the slider. Under the action of the restoring force of the spring, the connection between the hose and the connecting pipe can return to its original position after the movement, so that the probability of the hose being loosened due to bending is reduced, and the probability of the hose being damaged due to contact with molten iron is reduced, making the present invention more convenient to use.

[0026] Through the cooperation of the supporting device 2, the boom 6 and the boom 10, the metal dust is collected through the connecting pipe 4, the hose 5 and the collecting plate 12. When the boom 6 and the boom 10 rotate relative to each other, the hose 5 will be bent. At the same time, with the support of the two groups of first arc blocks 201 and the second arc blocks 205, the hose 5 can always move synchronously with the boom 6 and the boom 10. The operator disassembles the first bolts 202 and the second nuts 204 on both sides, and rotates the second arc block 205 around the connection between the rotating block 207 and the rotating shaft 206, so that the second arc block 205 can be opened and the hose 5 can be removed.

[0029] Through the cooperation of the traction device 9 and the slag scooping machine body 1, when the boom 6 and the dipper arm 10 move, the bent pipe 5 will be deformed and bent, and the bending will increase the required length of the bent pipe 5, so that the connection between the bent pipe 5 and the connecting pipe 4 moves toward the slag scooping rake 803. When the bent pipe 5 moves toward a straight state, the connection between the bent pipe 5 and the connecting pipe 4 will be pushed to move away from the slag scooping rake 803. When the hose 5 moves, the round sleeve 906 can be driven to move synchronously, so that the round sleeve 906 can drive the buckle 901 and the slider 903 moves synchronously, and the slider 903 slides on the surface of the slide rod 904 to fix the movement trajectory of the circular sleeve 906. When the circular sleeve 906 moves, the spring 902 can be compressed or stretched by the slider 903. Under the action of the restoring force of the spring 902, the connection between the hose 5 and the connecting pipe 4 can return to its original position after the movement, so that the probability of the hose 5 being loosened due to bending is reduced, and the probability of the hose 5 being damaged due to contact with molten iron is reduced, making the present invention more convenient to use.
[0030] The inner wall of the round sleeve 906 is fixedly connected to the outer wall of the hose 5, and the round sleeve 906 is made of steel.
[0031] Working principle: When using a mobile slag loader: The operator enters the control room 3 to operate the slag scraper body 1, and moves the slag scraper body 1 to the working point for operation through the crawler at the lower end of the slag scraper body 1. At the same time, the operator connects one end of the connecting pipe 4 to the external dust suction device, and places the external dust suction device on the frame installed on the outer wall of the slag scraper body 1, or disconnects the connecting pipe 4 and the dust suction device when the slag scraper body 1 is moving, so that the slag scraper body 1 can move normally. The operator controls the movement of the boom 6 and the arm 10, so that the arm 10 drives the straight plate 804 to move synchronously through the connecting plate 11, and drives the slag rake 803 through the straight plate 804 to clean impurities in the molten iron.
[0032] Replacement process: When the slag rake 803 is damaged or cannot meet the working requirements, the operator rotates the first nuts 801 on both sides to disassemble them. At the same time, the operator pulls the straight plate 804 so that the straight plate 804 can drive the cylinders 805 on both sides to separate from the two round rods 806, so that the straight plate 804 can drive the slag rake 803 to be removed. The disassembly of the slag rake 803 is completed. According to the above operation, the new slag rake 803 can be installed and fixed again. The conical grooves at one end of the cylinders 805 on both sides make it more convenient for the cylinders 805 to be sleeved onto the surfaces of the round rods 806 on both sides.
[0033] Dust removal process: When the slag rake 803 is working, a certain amount of metal dust will be generated. The external dust suction equipment is controlled to work, and the metal dust is collected through the connecting pipe 4, the hose 5 and the collecting plate 12. When the boom 6 and the arm 10 rotate relative to each other, the hose 5 will be bent. At the same time, under the support of the two groups of first arc blocks 201 and the second arc blocks 205, the hose 5 can always move synchronously with the boom 6 and the arm 10, so that the boom 6 and the arm 10 can work together when they move. After the hose 5 has been used for a long time, the operator disassembles the first flange 7 and the second flange 14 so that the hose 5 can be detached. At the same time, the operator disassembles the first bolts 202 and the second nuts 204 on both sides, so that the second arc block 205 rotates around the connection between the rotating block 207 and the rotating shaft 206, so that the second arc block 205 can be opened and the hose 5 can be removed. After replacing the new hose 5, the hose 5 can be connected and fixed again according to the above operations.
[0034] Hose Adjustment Procedure: When the boom 6 and the arm 10 move, the elbow 5 will be deformed and bent, and the bending will increase the required length of the elbow 5, so that the connection between the elbow 5 and the connecting pipe 4 moves toward the slag rake 803. When the elbow 5 moves toward a straight state, the connection between the elbow 5 and the connecting pipe 4 will be pushed to move away from the slag rake 803. When the hose 5 moves, the round sleeve 906 can be driven to move synchronously, so that the round sleeve 906 can drive the buckle 901 and the slider 903 to move synchronously (when replacing the hose 5, the operator The staff pulls the round sleeve 906 with force to make the round sleeve 906 disengage from the buckle 901), the slider 903 slides on the surface of the slide rod 904 to fix the movement trajectory of the round sleeve 906, and while the round sleeve 906 moves, the spring 902 can be compressed or stretched by the slider 903. Under the action of the restoring force of the spring 902, the connection between the hose 5 and the connecting pipe 4 can return to its original position after the movement, so that the hose 5 can reduce the probability of loosening due to bending, and reduce the probability of damage caused by contact between the hose 5 and molten iron.
