Description

Technical Field

[0001] This utility model relates to the field of metallurgical slag removal technology, and in particular to a slag removal device for metallurgy. Background Technology

[0002] Metallurgy is the process and technology of extracting metals or metal compounds from ores and processing them into metallic materials with certain properties using various processing methods. In the metallurgical process, steel slag in metallurgical waste is solid waste discharged during steelmaking, including converter slag and electric furnace slag. During the metallurgical process, waste slag is usually cleaned, and during the cleaning of these waste slags, they are usually screened to facilitate the separation of powdery and solid particulate matter.

[0003] Currently, after the slag produced in metallurgy is taken out of the metallurgical furnace and cooled, the cooled slag is transferred to a conveyor belt and then transported to a filtration mechanism. The powder and solid particles are screened through the filter screen in the filtration mechanism. However, the existing filtration device only screens the powder and solid particles through the filter screen and cannot shake off the powder adhering to the outer surface of the solid particles. As a result, the powder cannot be separated from the solid particles, which affects the cleaning effect of solid slag. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a slag removal device for metallurgy, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slag removal device for metallurgy, comprising:

[0006] The slag removal box has two annular plates rotatably installed in its inner cavity. Multiple filter screens for filtering waste residue are detachably installed between the two annular plates in a ring shape.

[0007] A support plate is rotatably installed between two annular plates, and multiple stirring plates for stirring waste residue are fixedly installed in a ring at one end of the support plate.

[0008] The feed pipe is fixedly installed on the top of the slag removal box, and the two filter screens have grooves at their adjacent ends that are compatible with the feed pipe.

[0009] The recycling bin is fixedly installed directly below the slag removal bin. A discharge pipe is fixedly installed at the bottom of the slag removal bin, and a feed chute adapted to the discharge pipe is opened at the top of the recycling bin. A screening screen plate for further filtering of waste residue is fixedly installed in the inner cavity of the recycling bin.

[0010] As a further description of the above technical solution:

[0011] The filter screen is curved, and the width of the filter screen is the same as the distance between the adjacent ends of the annular plate.

[0012] As a further description of the above technical solution:

[0013] The top of the slag removal box is provided with an installation groove that matches the feed pipe. One end of the feed pipe extends through the installation groove to the top of the filter screen, and the end of the feed pipe extending to the top of the filter screen is bent.

[0014] As a further description of the above technical solution:

[0015] One of the annular plates has through holes at the end away from the support plate and at the end of the slag removal box. A drive shaft is fixedly installed at the end of the support plate near the through holes. The end of the drive shaft away from the annular plate passes through the two through holes and extends to the outside of the slag removal box. A drive motor for rotating the drive shaft is fixedly installed at the end of the slag removal box near the through holes.

[0016] As a further description of the above technical solution:

[0017] Another annular plate has a drive shaft fixedly installed at the end away from the support plate, and a worm gear fixedly installed at the end of the drive shaft away from the annular plate.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, after the waste slag is collected between multiple filter screens and two annular plates, the support plate is rotated, causing multiple stirring plates to rotate together with the support plate. At this time, the rotating support plate and stirring plates push the waste slag to rotate as well. The rotating waste slag collides with each other, and at the same time, the rotating waste slag collides with the filter screens and the outer wall of the annular plates, causing the waste slag to vibrate due to the collision. At this time, the powder mixed in with the solid particles passes through the filter screens and falls into the inner cavity of the slag removal box. When the solid particles vibrate, the powder attached to the outer surface of the solid particles is shaken off, thus separating the powder attached to the outer surface of the solid particles from the solid particles, improving the cleaning effect of solid slag.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-4 One embodiment of this utility model is a slag removal device for metallurgy, comprising:

[0030] The slag removal box 1 has two annular plates 9 rotatably installed in its inner cavity. Multiple filter screens 6 for filtering waste residue are detachably installed in a ring between the two annular plates 9. The filter screens 6 are bent and installed between the two annular plates 9. The shape of the multiple filter screens 6 assembled is the same as that of the annular plates 9. After the waste residue is poured between the two annular plates 9, the powdery material passes through the filter screens 6 and falls into the inner cavity of the slag removal box 1, while the solid particles are trapped between the two annular plates 9, thereby realizing the screening and separation of powdery material and solid particles.

[0031] When multiple filter screens 6 are installed between two annular plates 9, the two adjacent filter screens 6 are in close contact with each other, reducing the distance between the two adjacent filter screens 6 and preventing solid particles from falling between the two adjacent filter screens 6.

[0032] The width of the filter screen 6 is the same as the distance between the adjacent ends of the annular plates 9. When the filter screen 6 is installed between the two annular plates 9, the two sides of the filter screen 6 and the adjacent ends of the two annular plates 9 are fitted together to prevent large gaps from remaining between the side wall of the filter screen 6 and the annular plates 9, which would cause solid particles to fall between the filter screen 6 and the annular plates 9, and prevent the powdery material that falls into the slag removal box 1 from mixing with the solid particles again.

[0033] A support plate 13 is rotatably installed between two annular plates 9, and multiple stirring plates 12 for stirring waste slag are fixedly installed in a ring at one end of the support plate 13. When the waste slag is collected between multiple filter screens 6 and two annular plates 9, the support plate 13 is rotated, causing the multiple stirring plates 12 to rotate together with the support plate 13. At this time, the rotating support plate 13 and stirring plates 12 push the waste slag to rotate. The rotating waste slag collides with each other, and at the same time, the rotating waste slag collides with the filter screens 6 and the outer wall of the annular plates 9, causing the waste slag to vibrate. At this time, the powder mixed in with the solid particles passes through the filter screens 6 and falls into the inner cavity of the slag removal box 1. When the solid particles vibrate, the powder attached to the outer surface of the solid particles is shaken off, which can separate the powder attached to the outer surface of the solid particles from the solid particles, thus improving the cleaning effect of solid slag.

[0034] The feed pipe 2 is fixedly installed on the top of the slag removal box 1. The two filter screens 6 have grooves at their adjacent ends that are compatible with the feed pipe 2. The waste residue can be concentrated and poured between the two annular plates 9 through the grooves.

[0035] The top of the slag removal box 1 is provided with an installation groove that is compatible with the feed pipe 2. One end of the feed pipe 2 extends through the installation groove to the top of the filter screen 6, and the top of the feed pipe 2 extends to the top of the slag removal box 1. The waste slag is poured into the inside of the feed pipe 2 through the top of the feed pipe 2. Under the action of gravity, the waste slag quickly passes through the groove and falls between the two annular plates 9.

[0036] The feed pipe 2 extends to one end directly above the filter screen 6 and is bent. The degree of bending at the bottom of the feed pipe 2 is the same as that at the filter screen 6. At the same time, the bottom of the feed pipe 2 is in close contact with the outer wall of the filter screen 6, which increases the contact area between the bottom of the feed pipe 2 and the top of the filter screen 6. This also reduces the distance between the bottom of the feed pipe 2 and the outer wall of the filter screen 6, preventing solid particles from falling between the feed pipe 2 and the filter screen 6 into the slag removal box 1 and becoming unable to shake off the powdery material adhering to the outer wall. This improves the removal effect of powdery material on the surface of solid particles.

[0037] The recycling box 3 is fixedly installed directly below the slag removal box 1. A discharge pipe 10 is fixedly installed at the bottom of the slag removal box 1. The top of the recycling box 3 has a feed chute adapted to the discharge pipe 10. A screening screen plate 4 for further filtration of the waste residue is fixedly installed inside the recycling box 3. After the powdery material adhering to the outer surface of the solid particles is removed by the stirring plate 12, the two annular plates 9 are rotated, thereby changing the angle between the groove and the discharge pipe 10, causing the groove to continuously move closer to the discharge pipe 10. At this time, the solid particles, wrapped by multiple filter screens 6 and the two annular plates 9, pass through the groove under the action of gravity. Solid particles falling into the slag removal box 1 slide down the inner wall of the slag removal box 1 and into the discharge pipe 10. They then fall into the inner cavity of the recovery box 3 through the discharge pipe 10. The solid particles falling into the recovery box 3 fall directly above the screening screen plate 4. When the solid particles collide with the screening screen plate 4, they vibrate, which helps to shake off the powder adhering to their outer surface. At the same time, it can also perform secondary filtration of waste residue, allowing the powder mixed in with the solid particles to pass through the screening screen plate 4, thus achieving secondary screening of the powder and solid particles.

[0038] The screening screen plate 4 is inclined inside the recycling box 3, and a recycling trough is opened on one side of the recycling box 3. Solid particles that fall on the top of the screening screen plate 4 slide down along the screening screen plate 4 under the action of gravity and fall into the outside of the recycling box 3 through the recycling trough. This prevents a large amount of solid particles from accumulating on the top of the screening screen plate 4, which would hinder the subsequent processing of waste residue. It also facilitates the centralized collection of the screened solid particles.

[0039] One of the annular plates 9 has through holes at one end away from the support plate 13 and at one end of the slag removal box 1. A drive shaft 5 is fixedly installed at the end of the support plate 13 near the through holes. The end of the drive shaft 5 away from the annular plate 9 passes through the two through holes and extends to the outside of the slag removal box 1. A drive motor for rotating the drive shaft 5 is fixedly installed at the end of the slag removal box 1 near the through holes. The power output end of the drive motor is fixedly connected to the end of the drive shaft 5 extending to the outside of the slag removal box 1. After the drive motor is started, the drive shaft 5 can be rotated, thereby causing multiple stirring plates 12 to rotate together with the support plate 13, thus stirring the waste slag located between the two annular plates 9.

[0040] Another annular plate 9 has a drive shaft fixedly installed at the end away from the support plate 13. A worm gear 7 is fixedly installed at the end of the drive shaft away from the annular plate 9. A transmission motor is fixedly installed at the end of the slag removal box 1 away from the through hole. A worm 8 that meshes with the worm gear 7 is fixedly installed at the power output end of the transmission motor. The worm 8 can limit the worm gear 7. When it is necessary to adjust the angle between the groove and the discharge pipe 10, the transmission motor is started, and the worm 8 rotates together with the power output end of the transmission motor. When the worm 8 rotates, the worm gear 7 can rotate accordingly, thereby making the annular plate 9 rotate together with the drive shaft. Since the two annular plates 9 are connected together by multiple fixed plates 11 arranged in a ring, the other annular plate 9 rotates accordingly, thus realizing that the two annular plates 9 rotate together. When the power output end of the transmission motor stops rotating, the rotated annular plate 9 can be positioned, which is beneficial for adjusting the distance between the groove and the discharge pipe 10 and the feed pipe 2, and improves the stability of the annular plate 9 when the waste is poured between the two annular plates 9.

[0041] Multiple fixing plates 11 are fixedly installed in a ring-shaped arrangement between the two annular plates 9. Multiple filter screens 6 are detachably connected to the outer wall of the multiple fixing plates 11 by bolts. The multiple ring-shaped fixing plates 11 can connect and support the two annular plates 9, as well as support the multiple filter screens 6, thereby improving the strength of the multiple filter screens 6.

[0042] According to the above embodiment, since the waste residue has a certain gravity, the filter screen 6 is prone to deformation after long-term use due to the gravity of the waste residue. The distance between the side wall of the deformed filter screen 6 and one end of the annular plate 9 increases, causing the waste residue to fall between the filter screen 6 and the annular plate 9. Therefore, the deformed filter screen 6 can be quickly replaced by bolts to prevent adverse effects on the normal filtration of waste residue.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
