Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurizing agent production, and in particular relates to a packaging device for a composite desulfurizing agent for washing molten steel refining slag. Background Art

[0002] Slag washing refers to a method of refining outside the furnace in which the molten steel initially refined in the steelmaking furnace is used to wash the synthetic slag in the ladle with molten steel to further improve the quality of the molten steel. The composite desulfurizer is also called a composite flue gas desulfurizer. It is an integrated flue gas desulfurizer made by mixing multiple components. It is widely used in power plants, chemical industry, steel and other industrial fields. Its function is to purify sulfur dioxide in the exhaust gas through absorption, oxidation, reduction and other processes. After the production of the composite desulfurizer is completed, it needs to be finally packaged by packaging equipment.

[0003] Oxidative desulfurizer is a common desulfurizer for steelmaking, with oxides as main components, such as calcium oxide (CaO), aluminum oxide (Al2O3), etc. Since the above-mentioned materials are small in particle size and easily dispersed in the air with the flow of air, when the oxidative desulfurizer is packaged in the prior art, as the materials are put into the packaging bag from the storage bin, the desulfurizer is easy to escape with the air discharged from the bag, thereby polluting the production environment, which not only affects the health of the operators, but also causes the loss of materials.

[0033] Embodiment 1:

[0034] like Figure 1—5 shows: a packaging device for a composite desulfurizer for washing slag from molten steel refining, comprising a discharge pipe 1, an outer tube body 2 is arranged on the outer side of the discharge pipe 1, an exhaust pipe 11 is connected to the side of the outer tube body 2, a pressure plate 3 is connected to the bottom end of the outer tube body 2 by bolts, a filter screen 4 is clamped between the pressure plate 3 and the outer tube body 2, the filter screen 4 is sleeved on the outer side of the discharge pipe 1, an annular shell 6 is installed on the discharge pipe 1 above the filter screen 4, a knocking assembly 7 and a lower transmission assembly 8 are rotatably installed on the annular shell 6, the knocking assembly 7 is transmission-connected to the lower transmission assembly 8, The top end of the lower transmission assembly 8 is connected to the upper transmission assembly 9, and the upper transmission assembly 9 is connected to the reduction motor 10 through the belt transmission assembly 12. The reduction motor 10 is installed on the outside of the outer tube body 2. The top end of the discharge pipe 1 is installed with a discharge valve 13, and the discharge valve 13 is installed on the discharge port of the storage bin 14. When discharging, the gas in the bag enters the cavity formed between the outer tube body 2 and the discharge pipe 1 and is then discharged through the exhaust pipe 11, and the powdered material in the gas is filtered and blocked by the filter screen 4, so that the gas in the bag is effectively discharged while preventing the material from escaping;The reduction motor 10 drives the knocking assembly 7 to rotate and knock the top surface of the filter 4 through multiple transmission mechanisms to shake out the material in the sieve hole, ensuring the long-term and stable use of the filter 4. A convex ring 5 is arranged on the outer surface of the outer tube body 2. The convex ring 5 is a circular ring structure, and the convex ring 5 plays a limiting role. After the outer ring of the bag mouth is tied with a tie or a rope body fixed on the outer side of the outer tube body 2, the convex ring 5 can effectively prevent the rope body from slipping off the outer tube body 2. The bottom end of the outer tube body 2 expands outward from top to bottom to form a conical structure. After the bottom end of the outer tube body 2 is expanded outward, the surface of the filter 4 installed at the bottom of the outer tube body 2 can be increased. The pressure plate 3 and the filter screen 4 are both annular plate structures, and the number of bolts connecting the pressure plate 3 and the outer tube body 2 is multiple. The outer tube body 2 and the pressure plate 3 can firmly clamp the filter screen 4 under the locking of multiple bolts. The knocking assembly 7 includes a rotating shaft 71 and a knocking hammer 72. The knocking hammer 72 is installed at the end of the rotating shaft 71. The rotating shaft 71 is rotatably mounted on the outer side of the annular shell 6.

The bevel gear 2 82 is mounted on the bottom end of the main shaft 83. The main shaft 83 is rotatably mounted on the top surface of the annular shell 6. When the main shaft 83 rotates, the bevel gear structure drives the knocking assembly 7 to stably rotate and knock the top surface of the filter screen 4. The upper transmission assembly 9 includes a driven gear 91, which is mounted on the upper side of the main shaft 83. The driven gear 91 is meshed with the inner gear ring 92. The inner gear ring 92 is rotatably mounted on the inner side of the fixing ring 93, and the fixing ring 93 is mounted on the outer tube. The top surface of the body 2, the driving pulley in the belt transmission assembly 12 is installed on the output shaft of the reduction motor 10, and the driven pulley in the belt transmission assembly 12 is installed on the main shaft 83. The reduction motor 10 can drive multiple main shafts 83 to rotate stably and synchronously through the gear structure in the belt transmission assembly 12 and the upper transmission assembly 9. The number of the knocking assemblies 7 is multiple, and they are equidistantly arranged around the axis of the discharge pipe 1. Multiple evenly distributed knocking assemblies 7 can effectively knock different areas of the filter screen 4 when rotating, so as to quickly shake out the materials blocked in the sieve holes of the filter screen 4. ;

[0035] The working principle of this technical solution is: put the bag mouth of the packaging bag on the outside of the outer tube body 2, and make the bag port higher than the convex ring 5, and then tie the bag mouth to the outer tube body 2 with a rope or a cable tie to ensure the stability and sealing of the bag mouth position; then the operator opens the discharge valve 13, and the desulfurizer falls from the storage bin 14 into the discharge pipe 1 under the action of gravity. At this time, the gas in the packaging bag enters the outer tube body 2 through the sieve holes of the filter screen 4, and then is discharged through the exhaust pipe 11. The raised dust is filtered and blocked by the filter screen 4 to avoid material escape and loss; the reduction motor When the drive mechanism 10 is in operation, the coaxially mounted driven gear 91 is driven to rotate by the belt transmission assembly 12, and the driven gear 91 meshes with the driving inner gear ring 92 to drive the remaining driven gears 91 to rotate, so that the multiple driven gears 91 drive the main shaft 83 to rotate synchronously. When the main shaft 83 rotates, the bevel gear 2 82 installed at the bottom end meshes with the driving bevel gear 1 81 to rotate, and the bevel gear 1 81 drives the striking assembly 7 to rotate as a whole. The striking hammer 72 is driven by the rotating shaft 71 to repeatedly strike the filter screen 4, so that the materials blocked in the sieve holes of the filter screen 4 are shaken out to avoid blockage of the filter screen 4.
