Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for steel smelting, in particular to equipment for separating scrap iron and impurities. Background Art

[0002] Steel mills often need to use recycled steel for remelting. However, in the steel smelting process, it is best to have very few impurities on the top or bottom of the molten iron. This places high demands on the quality of the steel recycled from the waste materials entering the furnace for smelting. Scrap iron usually carries a lot of impurities. Therefore, before smelting molten steel, the impurity removal process of steel waste cannot be ignored. After the recycled scrap iron is stamped and crushed, the iron raw materials and impurities are initially separated. However, the separation process of iron raw materials and impurities is time-consuming and labor-intensive, and it is difficult to achieve a very high separation rate. For this reason, it is necessary for us to design a fast and efficient separation equipment to improve the separation efficiency of the iron raw materials and impurities entering the furnace for smelting. Utility Model Content

[0003] The utility model aims to preliminarily separate the iron raw materials and impurities from the waste iron after stamping and crushing, and improve the separation efficiency of the iron raw materials and impurities to be smelted into the furnace.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a scrap iron and impurity separation device, comprising a separation box, a separation support, a plurality of magnetic guide rods, a lifting assembly and a swing base, as well as a hydraulic cylinder for controlling the left and right sides of the swing base to rotate and swing, and an iron raw material conveyor belt and an impurity conveyor belt arranged on both sides of the separation box.

[0005] The separation box is open on the left and right sides, and a feed port is arranged at the upper end. The crushed mixed raw materials are put into the feed port by a conveying device and received by a separation support platform arranged horizontally in the middle of the separation box.

[0006] The upper end surface of the separation support is provided with a bearing groove, and a plurality of through holes are arranged in an array in the bearing groove, and all the through holes are sleeved with the shaft holes of the magnetic guide rod.

[0007] The magnetic guide rod is magnetic, and is vertically arranged above the lifting assembly, and is aligned with and penetrates the upper through hole one by one. The lifting assembly includes a lifting plate and a lifting cylinder. The lifting cylinder drives the lifting plate to realize lifting action, thereby controlling the lifting action of the magnetic guide rod in the bearing groove. The lifting cylinder is arranged in the middle of the swing base.

[0008] Positioning columns and bases are arranged at the four corners of the swing base. The positioning columns connect the swing base and the separation support platform up and down to maintain the overall swing. Several groups of hydraulic cylinders are arranged on both sides of the lower end surface of the swing base. The hydraulic cylinders on both sides drive the swing base to swing left or right, or maintain a horizontal supporting posture.

[0009] Further, a discharge port is provided on either the left or right side of the upper end surface of the separation platform, so as to assist the impurities to slide down to the impurity conveyor belt on the left after tilting, or assist the iron raw materials to slide down to the iron raw material conveyor belt on the right after tilting.

[0010] Further, after the magnetic adsorption guide rod adsorbs the iron raw materials, it lifts upward, leaving some residual fine iron raw material and impurity mixture in the bearing groove of the separation platform.

[0011] Further, a vibrator is provided on the lower end surface of the separation platform for fully vibrating and dispersing the crushed mixed raw materials.

[0012] Further, the mixture on the impurity conveyor belt is put into the feed port again through the circulating transfer mechanism, which can facilitate the multiple purification of the impurities and extract more useful iron raw materials.

[0013] Compared with the prior art, the present utility model adopts the above technical solutions and has the following technical effects:

[0014] The waste iron and impurity separation equipment uses magnetic adsorption guide rods with magnetism to pass through the iron raw material mixture from the bottom of the separation platform in an array manner, adsorb and lift the crushed and separated iron raw materials through magnetism. After leaving the separation platform, most of the remaining are impurities. After the swing base swings left and tilts, the impurities tilt and slide down to the impurity conveyor belt. After retracting the magnetic adsorption guide rods, when the iron raw materials fall on the separation platform and the swing base swings right and tilts, the iron raw materials tilt and slide down to the iron raw material conveyor belt. And the impurities separated once may still contain some iron raw materials, which can be separated again by this equipment, which is practical and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1 to 5 , this embodiment provides a waste iron and impurity separation device, including a separation box 2, a separation support platform 3, several magnetic suction guide rods 8, a lifting plate 9, a lifting cylinder 12 and a swing base 6, as well as hydraulic cylinders for controlling the left and right rotation and swing of the swing base 6 and the iron raw material conveyor belt 16 and impurity conveyor belt 15 arranged on both sides of the separation box 2. Using the magnetic suction guide rods with magnetism, the iron raw material mixture is passed through from the bottom of the separation support platform in an array manner, and the crushed and separated iron raw materials are adsorbed and lifted by magnetism. After leaving the separation support platform, most of the remaining are impurities. After the swing base swings and tilts to the left, the impurities tilt and slide onto the impurity conveyor belt. After retracting the magnetic suction guide rods, when the iron raw materials fall on the separation support platform and then the swing base swings and tilts to the right, the iron raw materials tilt and slide onto the iron raw material conveyor belt.

[0023] Refer to Figure 1 and Figure 4 , the separation box 2 has openings on both the left and right, and a feed inlet 1 is provided at the upper end. The crushed mixed raw materials are put into the feed inlet 1 by a conveying device and are received by the separation support platform 3 horizontally arranged in the middle of the separation box 2.

[0024] Refer to Figure 5 , a bearing groove 10 is provided on the upper end surface of the separation support platform 3, and a number of through holes 13 are arrayed in the bearing groove 10. All the through holes 13 correspond to the magnetic suction guide rods 8 one by one and are sleeved through the shaft holes.

[0025] Refer to Figure 2 and Figure 5 , the magnetic suction guide rods 8 have magnetism and are vertically arranged above the lifting assembly and are respectively aligned with and inserted into the upper through holes 13. The lifting assembly includes a lifting plate 9 and a lifting cylinder 12. The lifting cylinder 12 drives the lifting plate 9 to perform a lifting action, thereby controlling the lifting action of the magnetic suction guide rods 8 in the bearing groove 10. The lifting cylinder 12 is arranged in the middle of the swing base 6.

[0026] Refer to Figure 1, positioning columns 4 and pedestals 5 are provided at the four corners of the swing base 6. The positioning columns 4 connect the swing base 6 and the separation table 3 up and down to maintain the overall swing. Four sets of hydraulic cylinders are provided on both sides of the lower end face of the swing base 6, and the hydraulic cylinders on both sides drive the swing base 6 to swing left and right, or maintain a horizontal supporting posture.

[0027] Refer to Figure 3 , a discharge port 14 is provided on the left side of the upper end face of the separation table 3, so as to facilitate the auxiliary impurities to slide down to the left impurity conveyor belt 15 after tilting, or the auxiliary iron raw materials to slide down to the right iron raw material conveyor belt 16 after tilting.

[0028] Refer to Figure 5 , after the magnetic attraction guide rod 8 adsorbs the iron raw materials, it lifts upward, leaving part of the remaining fine iron raw material and impurity mixture in the bearing groove 10 of the separation table 3.

[0029] A further implementation scheme is that a vibrator (not shown in the figure) is provided on the lower end face of the separation table 3, which is used to vibrate and disperse the crushed mixed raw materials sufficiently, so as to facilitate the magnetic attraction guide rod to fully adsorb the column iron raw materials.

[0030] A further implementation scheme is that the mixture on the impurity conveyor belt 15 is put into the feed port 1 again through a circulating transfer mechanism (not shown in the figure), which can facilitate the multiple purification of impurities and extract more useful iron raw materials.
