DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 The figure shows a steel and wire rod smelting and purification equipment, which includes a furnace body 1, a slag removal assembly and a lifting assembly. A cover body 2 is provided above the furnace body 1, and the cover body 2 and the furnace body 1 are connected by a lifting component; the slag removal assembly is installed inside the furnace body 1 to remove impurities on the surface of the molten iron smelted inside the furnace body 1; the lifting assembly is installed on the cover body 2 to enable the slag removal assembly to be lifted and lowered inside the furnace body 1.

[0023] See also Figure 2-Figure 4 The slag removal assembly shown in the figure includes a plurality of arc plates 3 arranged in a circumferential manner, and the plurality of arc plates 3 are spliced ​​into a conical barrel in a circumferential array, and each arc plate 3 is provided with a filter hole 4, and a bracket 5 is provided on one side above the arc plate 3, and one side of the inner wall of each arc plate 3 is connected to the bracket 5 through a first hinge shaft 6;

[0024] See also Figure 2-Figure 4The slag removal assembly shown in the figure also includes a hollow tube 7 fixed in the middle of the bracket 5, a rotating rod 10 is inserted into the interior of the hollow tube 7, one end of the rotating rod 10 extends to the outside of the hollow tube 7 and is fixedly connected to the screw rod 8, a nut 9 is threaded on the screw rod 8, and a movable rod 11 is equidistantly provided on the side wall of the nut 9, both ends of the movable rod 11 are respectively connected to the arc plate 3 and the nut 9 through a second hinge shaft 12, and one end of the hollow tube 7 passes through the cover body 2 and extends outward to be connected to the lifting assembly.

[0025] When melting steel and wire rods: first, open the cover 2 through the lifting component, put the steel and wire rods to be melted into the furnace, and then close the cover 2 to make the furnace melt the steel and wire rods inside. After the steel is melted into molten iron, the impurities mixed in the steel will float above the molten iron. At this time, the staff rotates the screw 8, and the rotation of the screw 8 will drive the nut 9 to move. Since the movable rod 11 is connected to the second hinge shaft 12 and the arc plate 3, and the arc plate 3 is connected to the bracket 5 through the first hinge shaft 6, and the bracket 5 is connected to the hollow tube 7, and the hollow tube 7 is connected to the lifting component, this The rotation of the screw rod 8 can drive the nut 9 to move up and down on the screw rod 8. When the nut 9 moves downward, it can push the movable rod 11. At the same time, the movable rod 11 pushes the arc plate 3. Since the arc plate 3 is connected to the bracket 5 through the first hinge shaft 6, the movable rod 11 pushes the arc plate 3 to make the arc plate 3 rotate in a circle with the first hinge shaft 6, so that the arc plate 3 arranged in a circle is unfolded. After the arc plate 3 is unfolded, the rotation of the screw rod 8 is notified. The unfolding of the arc plate 3 can reduce the contact area between the outer wall of the arc plate 3 and the molten iron in the horizontal direction, reduce the contact between the arc plate 3 and the molten iron to avoid impurities.

[0026] After the arc plate 3 is unfolded, the lifting assembly is started to drive the hollow tube 7 to descend. The descent of the hollow tube 7 can drive the slag removal assembly to descend, so that the unfolded arc plate 3 is inserted into the molten iron after smelting. After the arc plate 3 is completely inserted into the molten iron, the screw rod 8 is rotated in the opposite direction to drive the nut 9 to rise, so that the nut 9 pulls the movable rod 11 to rise, and the movable rod 11 pulls the arc plate 3 to rotate in the opposite direction with the first hinge shaft 6 as the center, so that a plurality of arc plates 3 arranged in a circular array can be closed to form a hollow cone, and then the lifting assembly is started again to drive the lifting assembly to rise, so that the slag removal assembly can be driven to rise, so that the arc plate 3 can be raised. When the plurality of arc plates 3 arranged in a circular array and closed to form a hollow cone rise, they can play a role in salvaging and lifting impurities floating on the surface of the molten iron. At the same time, the arc plate 3 is provided with a filter hole 4. At this time, the molten iron salvaged together will drip through the filter hole 4, so that the impurities are salvaged and filtered between the arc plates 3, so that the impurities on the surface of the molten iron inside the furnace body 1 can be removed.

[0027] When the impurities salvaged between the arc plates 3 need to be discharged, the cover body 2 is driven to open by the lifting component, and then the screw 8 is rotated to drive the arc plates 3 to unfold. A receiving container is placed under the arc plates 3 to receive and collect the impurities that fall when the arc plates 3 are unfolded.

[0028] The device has a simple structure and is easy to operate. By adding a cover body 2, a slag removal component and a lifting component used in conjunction, the arc plates 3 arranged in a circular array can be closed to form a hollow cone to salvage and filter impurities floating on the surface of molten iron inside the furnace body 1 to remove slag, avoiding the need for workers to climb and use tools to salvage and filter, effectively reducing the labor intensity of workers, improving the safety of workers' operation and use, and greatly improving the work efficiency of steel and wire rod smelting processing.

[0033] In the present embodiment, the lifting assembly can drive the hollow tube 7 to rise and fall. When the slag removal assembly is needed to remove floating impurities on the molten iron inside the furnace body, the first hydraulic cylinder 15 is started. The first hydraulic cylinder 15 is started to drive the first hydraulic rod 14 to contract, which can drive the cross plate 13 to descend in the vertical direction of the furnace body 1, so that the hollow tube 7 installed on the cross plate 13 descends, and the slag removal assembly can be driven to descend into the molten iron; when the first hydraulic cylinder 15 drives the first hydraulic rod 14 to extend, the cross plate 13 is pulled up to separate the slag removal assembly from the molten iron, which can prevent the slag removal assembly from being damaged by being immersed in high-temperature molten iron for a long time, and effectively improve the safety of the use of the slag removal assembly.

[0034] A lifting component is provided on the cover body 2, which can realize the opening and closing between the cover body 2 and the furnace body 1.
