Description

Technical Field

[0001] The utility model relates to the technical field of water slag treatment, in particular to an iron removal device for water slag treatment. Background Art

[0002] Water slag refers to blast furnace slag from ironmaking. It is in a high-temperature molten state and rapidly cooled with water to form a granulated foam shape. It is milky white, light, crisp, porous, and easy to grind into fine powder. It is a soft material for foamed silicate building products, slag sound-absorbing bricks, insulation layers, and water-absorbing layers. Water slag is formed by rapidly cooling molten blast furnace slag in water. There are mainly two methods: slag pool water quenching and furnace front water quenching. Due to the short separation time between slag and iron, or the poor efficiency of the separation equipment, certain metal iron particles are often mixed in the slag. If the iron in it is not recovered, it will not be conducive to cost saving and cause waste.

[0003] The existing blast furnace slag iron removal device usually sets a magnetic plate in the box body, so that the blast furnace slag passes through the magnetic plate after entering the box body, and uses the magnetism of the magnetic plate to recover the metallic iron in the blast furnace slag. However, this method has the following problems: the magnetic plate is usually set in the box body, and the box cover and the box body need to be twisted apart during the cleaning of the magnetic plate, which makes the removal process more cumbersome. At the same time, when the slag iron is removed, because the magnetic plate is set on the rotating shaft, and parts are connected to both ends of the rotating shaft, it is inconvenient to clean the slag iron in the magnetic plate. In addition, the existing device usually adopts a single iron removal structure, resulting in a low recovery efficiency of iron in blast furnace slag. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Example 1

[0028] In a typical embodiment of the present invention, a deironing device for slag treatment is provided, such as Figure 1 The figure shows a processing box 1, wherein a feeding hopper 2 is arranged on the top of the processing box 1, and a water outlet 26 is arranged on the bottom. A primary iron removal structure and a secondary iron removal structure are arranged in the processing box 1, and the primary iron removal structure is located on the upper part of the secondary iron removal structure; the primary iron removal structure is two magnetic barrels 8 which are arranged oppositely and can rotate, and the secondary iron removal structure is two electromagnetic columns 22 which are arranged oppositely. The water slag enters the processing box 1 from the feeding hopper 2, and is discharged from the water outlet after passing through the primary iron removal structure and the secondary iron removal structure in turn.

[0029] Specifically, the two magnetic barrels 8 are placed horizontally in the processing box 1, and the axes of the two magnetic barrels 8 are parallel and there is a certain distance between the two magnetic barrels 8 to allow the slag water to flow through. The magnetic barrels 8 are driven to rotate by the driving structure 31 installed on the processing box 1, so that the rotation directions of the two magnetic barrels are opposite, and the two magnetic barrels 8 rotate in opposite directions.

[0030] like Figure 4 As shown, the driving structure 31 includes a dual-axis motor 3, and the two output shafts of the dual-axis motor 3 are equipped with a driving bevel gear 5 through a connecting shaft 4. The driving bevel gear 5 is meshed with a driven bevel gear 6 installed on the end of the magnetic barrel 8 through a rotating shaft 7. The magnetic barrel 8 is driven to rotate by the dual-axis motor 3 and the bevel gear. The dual-axis motor can drive the two magnetic barrels to rotate by only one motor. The power transmission between the dual-axis motor and the magnetic barrels is achieved by setting the driving bevel gear and the driven bevel gear, so that the rotation directions of the two magnetic barrels are opposite.

[0031] Furthermore, an iron chip stripping seat 9 is provided at the bottom of the magnetic barrel 8, and the iron chip stripping seat 9 is fixedly installed inside the processing box. The top of the iron chip stripping seat 9 is an arc structure adapted to the shape of the magnetic barrel 8. The bottom of the magnetic barrel 8 fits with the top of the iron chip stripping seat 9. There is a water slag circulation space between the two magnetic barrels 8. The space between the outer sides of the two magnetic barrels 8 and the processing box is connected with an iron chip collecting box 10. The iron chip collecting box 10 is located on the outer side of the iron chip stripping seat 9. The magnetic barrel absorbs iron chips flowing through the water slag during rotation. When it rotates to the position of the iron chip stripping seat 9, the iron chip stripping seat 9 is used to remove the iron chips absorbed on the magnetic barrel, so that the iron chips fall into the iron chip collecting box 10 below. The iron chip collecting box 10 adopts a pull-out structure and is opened at the top. Two handles 11 are provided on the side wall surface of the iron chip collecting box 10 outside the processing box. When there are a lot of iron chips collected in the iron chip collecting box 10, the iron chip collecting box 10 can be pulled out to clean it. The iron filings stripping seat 9 is provided to remove the iron filings adsorbed on the magnetic barrel. In the process of cleaning the iron filings, there is no need to disassemble the magnetic barrel, which is convenient to operate and improves the iron removal efficiency.

[0032] Furthermore, the water slag circulation space is connected to the space where the second iron removal structure is located. The space where the second iron removal structure is located is provided with two inclined plates 23 and two electromagnetic structures. The electromagnetic structure is an electromagnetic column 22. Specifically, the first inclined plate is arranged opposite to the first electromagnetic structure, and the second inclined plate is arranged at the lower part of the first electromagnetic structure. The second inclined plate is arranged opposite to the second electromagnetic structure. The water slag after the first-stage iron removal enters the space where the electromagnetic structure is located. The water slag flows onto the first inclined plate, and the iron is removed by the first electromagnetic structure. Then, it flows onto the second inclined plate, and the iron is removed by the second electromagnetic structure. The two inclined plates are provided to increase the flow distance of the water slag, so that the water slag is further de-ironized by the first electromagnetic structure and the second electromagnetic structure in the process of flowing through the first inclined plate and the second inclined plate, thereby improving the iron removal efficiency of the water slag.

[0033] Furthermore, the electromagnetic structure includes an electromagnetic column 22 installed on a connecting block 21, and a plurality of electromagnetic columns 22 are provided. The connecting block 21 is connected to the power supply machine 13 through a protective shell 18, and the power supply machine 13 provides electric energy to the electromagnetic column 22. The electromagnetic column has magnetism after being energized, and the magnetism of the electromagnetic column is used to adsorb iron filings in the slag.

[0034] Furthermore, if Figure 5As shown, the output end of the power supply 13 is provided with a mounting thread 14 and a mounting slide 15. The mounting slide 15 can be engaged in the groove on the protective shell 18. The mounting slide 15 is limited by providing a mounting nut 19 and a limit nut 20 on the mounting thread 14, and the protective shell 18 is connected to the output end of the power supply 13. The protective shell 18 is used to protect the wires connecting the electromagnetic column and the power supply. An unlocking rod 16 is fixedly connected to one end of the mounting slide 15. The outer sleeve of the unlocking rod 16 is provided with a mounting spring 17. When installing the protective shell 18, the protective shell 18 is inserted into the output end of the power supply 13. The mounting slide 15 is pushed into the groove inside the protective shell 18 under the action of the mounting spring 17. Then, the mounting slide 15 is limited by the mounting nut 19 and the limit nut 20, thereby completing the installation.

[0035] In a specific implementation of the present embodiment, two mounting slides 15 are provided on each power supply machine 13, and the two mounting slides are symmetrically arranged up and down, and the position where the mounting slide is engaged with the protective shell 18 is an inclined surface, and the end of the mounting slide can be made to enter the groove on the protective shell 18 by pushing the protective shell, and the other end of the mounting slide is arranged in a cylindrical cavity, one end of the unlocking rod 16 is located in the cylindrical cavity and connected to the end of the mounting slide, and the other end passes through the cylindrical cavity, and the unlocking rod is limited by a set boss, and the slider can be pulled to move in the cylindrical cavity by pulling the unlocking rod 16, and under the action of the spring 17, the mounting slide 15 is pressed into the groove on the protective shell 18, and when the protective shell and the power supply machine need to be disassembled, the boss at the end of the unlocking rod is pulled outward to make the mounting slide be pulled out of the groove on the protective shell.

[0036] Furthermore, by arranging a groove in the middle of the mounting slide block, the mounting nut can be rotated into the groove of the mounting slide block to fix the mounting slide block, and further limited by the limiting nut.

[0037] Furthermore, the electromagnetic structure, power supply and other structures are installed in a drawer-shaped sliding box, such as Figure 3 As shown, fixed plates 29 are fixedly connected to both sides of the sliding box, and four fixed plates 29 are fixedly connected to the processing box 1 by fixing screws 30. The secondary iron removal structure 12 can be moved as a whole through the sliding box. The electromagnetic column 22 can absorb the leaked iron filings under the action of the power supply machine 13, and the electromagnetic column 22 can be easily cleaned by pulling out the sliding box.

[0038] In this embodiment, a filter plate 24 is provided at the water outlet 26. The filter plate 24 is slidably connected to the treatment box 1. A pull ring 25 is fixedly connected to one end of the filter plate 24. The filter plate 24 can be pulled out by pulling the pull ring 25, and then the filter plate 24 can be cleaned or replaced to prevent blockage above the water outlet 26.

[0039] In this embodiment, if Figure 2 As shown, the four corners of the bottom of the processing box 1 are fixedly connected with a base 27, and the inner wall of one side of the processing box 1 is fixedly connected with an observation glass plate 28. The stability of the device can be enhanced through the base 27, and the operation status inside the device can be observed through the observation glass plate 28 to ensure stable operation of the device.

[0040] The working principle of the iron removal device for slag treatment provided in this embodiment is as follows:

[0041] By starting the double-axis motor 3, the connecting shafts 4 on both sides are driven to rotate, and then the driven bevel gear 6 is driven to rotate through the active bevel gear 5, and then the magnetic barrel 8 is driven to rotate. The magnetic barrel 8 continuously rotates from the water slag to achieve the adsorption of iron, and the iron removal operation of the water slag is completed;

[0042] The electromagnetic column 22 can absorb the leaked iron filings under the action of the power supply machine 13, completing the secondary iron removal operation of the water slag;

[0043] After the iron removal is completed, the water slag is filtered through the filter plate 24 and discharged from the water outlet.

[0044] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model.
