Technical Field

[0001] This utility model relates to the field of ironmaking slag separation technology, specifically to a multi-stage ironmaking slag separation device. Background Technology

[0002] Ironmaking is a process of refining metallic iron from iron-containing minerals (mainly iron oxides). During the refining process, blast furnace slag is rapidly cooled in water to produce water slag, which contains a large amount of iron slag. Separating the iron slag from the water slag is essential.

[0003] Existing ironmaking slag separation devices require a separate water filtration device to filter the water from the slag before using a magnetic separation device to separate the iron slag. This results in low continuity of operation and a high amount of waste residue during magnetic separation, which affects the effectiveness of the separation process. Utility Model Content

Example

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a multi-stage separation device for ironmaking slag, which is equipped with a feeding component 1, a separation box 2 and a filtration hopper 5 in order to perform preliminary water filtration on the slag and achieve continuous feeding. The feeding assembly 1 is inclined and movably mounted on one side of the separation box 2 via a bracket 12, with the top discharge end of the feeding assembly 1 positioned directly above the separation box 2. Multiple water-filtering hoppers 5 are spaced apart on the conveying path of the feeding assembly 1 via rivets 51, and each water-filtering hopper 5 has multiple water-filtering holes 52. A support 11 is provided at the lower end of the feeding assembly 1 for support, and the 11 is fixed to the ground to ensure the stability of the feeding assembly 1 during operation. The middle of both sides of the feeding assembly 1 is connected to the separation box 2 via the bracket 12. Both ends of the bracket 12 are rotatable, and the tilt angle of the feeding assembly 1 can be adjusted by adjusting the fixed position of the support 11 to accommodate separation boxes 2 of different heights. A first driving mechanism 13 is provided on the upper side of one side of the feeding assembly 1. 13 is used to drive the conveying component of the feeding assembly 1. An inclined plate 21 is provided inside the separation box 2. The inclined plate 21 is located below the discharge end of the feeding assembly 1 and above the screening assembly 3. The inclined plate 21 is used to facilitate the material to enter the interior of the screening assembly 3. The separation box 2 is provided with a first discharge port 22 and a second discharge port 23. The first discharge port 22 is located on the discharge side of the opening of the screening assembly 3. The second discharge port 23 is located below the magnetic separation assembly 4. The first discharge port 22 is used to facilitate the discharge of large particles of waste residue separated by the screening assembly 3. The second discharge port 23 can facilitate the discharge of small particles of waste residue and the discharge of adsorbed iron slag. The separation box 2 is also provided with an openable maintenance door 24, which is used to open the maintenance door 24 for maintenance when the internal components are damaged. Example

[0016] In order to perform preliminary screening of the waste in the slag, a screening device 3 is installed; The screening assembly 3 is located inside the separation box 2 and below the discharge end of the feeding assembly 1. A first support mechanism 31 and a second support mechanism 32 are installed at both the top and bottom of the screening assembly 3. The second support mechanism 32 is only installed on the top of the discharge side of the screening assembly 3. The first support mechanism 31 and the second support mechanism 32 are both provided to ensure the stability of the screening mesh 34 during screening and to improve screening efficiency. The screening mesh 34 is connected to the separation box 2 via the first support mechanism 31 and the second support mechanism 32. When the vibrating motor 33 vibrates the screening mesh 34, the vibration frequency of the screening mesh 34 is relatively high, facilitating the screening of water slag. The screening assembly 3 includes a screening mesh 34, with a vibrating motor 33 installed at one top end of the screening mesh 34. The vibrating motor 33 drives the screening mesh 34 to vibrate for screening. The first support mechanism 31 includes a first support mechanism 32. The assembly includes a mounting plate 311, an L-shaped support plate 312, and a spring 313. The mounting plate 311 is connected to the separation box 2 via fasteners. The first support mechanism 31 and the second support mechanism 32 are both fixed to the inner wall of the separation box 2 via the mounting plate 311. The L-shaped support plate 312 is used to connect the mounting plate 311 and the spring 313. The L-shaped support plate 312 and the mounting plate 311 are welded together. The spring 313 is welded to the bottom of the L-shaped support plate 312 via connecting blocks at both ends. The upper side of the spring 313 is installed on the bottom of the L-shaped support plate 312, and the lower side of the spring 313 is installed on the screening screen 34. When the vibrating motor 33 drives the screening screen 34 to vibrate, the spring 313 will extend and retract slightly with the vibration. This will not completely offset the vibration, nor will it excessively restrict the displacement of the screening screen 34. Instead, it will allow the screening screen 34 to maintain a stable amplitude and vibration frequency, thereby improving the screening efficiency. Example

[0017] In order to separate the iron slag in the slag, a magnetic separation component 4 is provided; The magnetic separation component 4 is rotatably installed inside the separation box 2 and located below the screening component 3. The magnetic separation component 4 includes a rotating shaft 41, electromagnetic plates 42, support columns 43 and a second drive mechanism 44. The four electromagnetic plates 42 are installed around the rotating shaft 41 through the support columns 43. The support columns 43 are hollow and have wires that connect to the electromagnetic plates 42 inside, so that users can control the electromagnetic plates 42 to adsorb and release iron slag through a mobile terminal. The power output end of the second drive mechanism 44 is connected to the rotating shaft 41, and the second drive mechanism 44 is fixed to one side of the separation box 2, and its power output end is connected to the rotating shaft 41.

[0018] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0019] In this invention, the working steps of the device are as follows: First, the feeding assembly 1 is started, and the first drive mechanism 13 drives its conveying components to add ironmaking slag into the filter hopper 5. The water in the slag is filtered out through the filter holes 52. The filtered slag is then conveyed to the top of the separation box 2 along with the filter hopper 5, and guided by the inclined plate 21 to fall onto the screening assembly 3 inside the separation box 2. Next, the vibrating motor 33 is started, driving the screening screen 34 to vibrate. The slag is vibrated and screened on the screening screen 34. Smaller waste slag particles fall through the screening screen 34 to the magnetic separation assembly 4, while larger ones... The material or the part that is not fully separated is discharged from the first discharge port 22 after vibration; then the remaining water slag falls onto the magnetic separation component 4, the iron slag is attracted by the electromagnetic plate 42, the second drive mechanism 44 drives the rotating shaft 41 to rotate, fully adsorbing the iron slag in the water slag, and the waste slag without iron slag is released through the second discharge port 23; finally, when it is necessary to remove the separated iron slag, the user can turn off the power to the equipment, the electromagnetic plate 42 loses power, and the iron slag adsorbed on the plate can be discharged through the second discharge port 23.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
