Description

Technical Field

[0001] The utility model relates to the field of converter charging equipment, in particular to a device for charging powder after a converter. Background Art

[0002] In the traditional converter steelmaking process, a large amount of molten slag is produced during smelting in the furnace. However, the chemical composition of slag is complex, especially the sulfur and phosphorus elements mixed in slag have a great impact on the quality of steel. When the converter molten steel is smelted and the molten steel is discharged, the amount of slag flowing into the ladle with the molten steel must be strictly controlled. For this reason, slag cones are usually used to screen out the steel slag process to prevent harmful elements such as sulfur and phosphorus from re-penetrating into the molten steel in the subsequent steelmaking process, causing the phenomenon of phosphorus return in the steelmaking process, thereby avoiding affecting the quality of the steel billet. At present, slag cone cars are generally used to put slag cones into the converter. The slag cone car has a fast forward and backward speed, good heat resistance of the big arm, and the end of the big arm can be raised and lowered. The end can penetrate 2-3 meters into the furnace. However, the traditional slag cone car is only used to put slag cones into the converter, and its function is relatively single. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution adopted by the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the utility model provides a device for adding powder after a converter, comprising: a slag blocking cone car 6 and a U-shaped groove rail 62 located on the large arm 61 of the slag blocking cone car 6, a material car 63 slidably connected to the U-shaped groove rail 62 is provided in the U-shaped groove rail 62, and a blocking car and cover opening member 64 is provided at one end of the U-shaped groove rail 62.

[0022] In this embodiment, the slag cone car 6 is a prior art, that is, by controlling the slag cone car 6, the arm 61 of the slag cone car 6 is tilted and extended into the converter, and the slag cone on the arm 61 of the slag cone car 6 slides from the tilted arm 61 into the converter under the action of its own gravity;

[0023] On this basis, the utility model arranges a U-shaped groove rail 62 and a material trolley 63 slidably connected to the U-shaped groove rail 62 on the arm 61 of the slag blocking cone trolley 6. When the arm 61 is tilted to drop the slag blocking cone into the converter, the material trolley 63 also slides into the converter along the inclined U-shaped groove rail 62 under the action of its own gravity. The material trolley 63 slides to the end of the U-shaped groove rail 62 and collides with the blocking and cover-opening member 64, thereby opening the material trolley 63, so that the powder in the material trolley 63 falls into the converter.

[0024] Specifically, Figure 2 , Figure 3 As shown, the material cart 63 includes a body with a cavity and a plurality of wheels 635 fixed on a T-shaped bottom plate 631 of the body, and the left and right sides of the body are movable side plates 632, and the movable side plates 632 are rotatably connected to the T-shaped bottom plate 631 through a first hinge shaft 633;

[0025] The front and rear ends of the vehicle body are baffles 636, and the baffles 636 are fixedly connected to the T-shaped bottom plate 631. The top of the vehicle body is a U-shaped card cover 634, and the two sides of the U-shaped card cover 634 can clamp the movable side plates 632. The two ends of the U-shaped card cover 634 can overlap the baffles 636 at the front and rear ends of the vehicle body, that is, the U-shaped card cover 634 and the two movable side plates 632, the two baffles 636 and the T-shaped bottom plate 631 form a cavity of the vehicle body, and the cavity is used to carry powder.

[0026] Further, such as Figure 4 As shown, the vehicle blocking and lid opening member 64 includes a fixing plate 641 vertically arranged with the U-shaped groove rail 62, and a lid opener 642 is arranged at one end of the fixing plate 641 facing the material vehicle 63, and the cross section of the lid opener 642 is a right triangle, and one of the two right angles of the right triangle is fixedly connected with the fixing plate 641, and the other is parallel to the U-shaped groove rail 62 and faces the overlap of the U-shaped card cover 634 and the front end baffle 636 of the vehicle body;

[0027] That is, when the material cart 63 moves along the U-shaped groove rail 62 to contact the blocking and cover-opening member 64, the cover opener 642 can open the U-shaped cover 634, and the movable side plate 632 opens the cavity through the first hinge shaft 633, so that the powder in the cavity falls into the converter.

[0028] Furthermore, a buffer spring 643 is provided below the cover opener 642 , one end of the buffer spring 643 is fixedly connected to the fixing plate 641 , and the other end of the buffer spring 643 faces the baffle 636 at the front end of the trolley 63 , providing a certain buffer for the trolley 63 .

[0029] Further, such as Figure 3 As shown, the baffle 636 at the rear end of the trolley 63 is provided with a hinge seat 66, and the hinge seat 66 is rotatably connected to one end of an L-shaped clamp 68 through a second hinge shaft 67. The other end of the L-shaped clamp 68 is clamped on the stop block 65, and the stop block 65 is fixed on the upper arm 61.

[0030] That is, when there is no need to add powder into the converter, the trolley 63 is fixed in the U-shaped groove rail 62 by clamping one end of the L-shaped clamp 68 on the stop block 65. When the upper arm 61 is tilted, the trolley 63 will not enter the converter together with the slag stop cone. When powder needs to be added to the converter, the handle of the L-shaped clamp 68 is pulled to disengage the L-shaped clamp 68 from the stop block 65. When the upper arm 61 is tilted, the trolley 63 will enter the converter together with the slag stop cone.

[0031] In addition, the feeding device of the equipment for adding powder after the converter is also provided with a feeding device, which is used to convey the powder into the feed car 63;

[0032] Specifically, Figure 5-7 As shown, the feeding device includes a material box 1 and a vibrating feeding device 4 located at the bottom of the material box 1 and connected to the material box 1. The vibrating feeding device 4 includes: an upper fixing ring 41 located at the bottom of the material box 1 and connected to the material box 1, the upper fixing ring 41 is connected to the lower fixing ring 43 through a telescopic bag section 42, and the lower fixing ring 43 is provided with a chute 44 connected thereto, and the discharge port of the chute 44 is directly opposite to the feeding device;

[0033] Specifically, powder is put into the material box 1 , and the powder enters the chute 44 through the telescopic bag section 42 , and then enters the material cart 63 through the chute 44 .

[0034] The outer wall of the material box 1 is fixedly connected to one end of a plurality of hanging springs 2, and the other ends of the plurality of hanging springs 2 are fixedly connected to the lower fixed ring 43; that is, the plurality of hanging springs 2 arranged between the material box 1 and the lower fixed ring 43 can play a certain buffering role on the powder entering from the material box 1, and can also prevent the powder from accumulating between the telescopic bag section 42 and the chute 44.

[0035] The chute 44 is provided with an electric vibrator 47 , which can drive the chute 44 to vibrate, so that the powder in the chute 44 can be more easily discharged from the discharge port of the chute 44 .

[0036] Furthermore, the discharge port of the chute 44 is provided with a plug plate seat 46, and a plug plate 45 slidably connected thereto is provided in the plug plate seat 46, so that the discharge port of the chute 44 can be opened and closed by controlling the plug plate 45 to slide in the plug plate seat 46.

[0037] Furthermore, the material box 1 can be fixedly connected to the trolley 5 via the bracket 3 to realize the movement of the entire feeding device.
