Description

Technical Field

[0001] This application relates to the field of slag technology, specifically to a rotary slag screening device. Background Technology

[0002] Slag is the residue formed after impurities produced during the smelting process are oxidized and separated from the metal. However, slag often contains a variety of valuable components, such as metals, glass, and ceramics. Screening is required to separate these components from the slag and enable the reuse of resources.

[0003] Among them, the rotary slag screen is a commonly used device for slag processing. It separates different particles in the slag by rotating.

[0004] For example, the patent with announcement number CN111744761A specifically discloses a slag sorting roller screen. This patent has two rollers with different filter hole sizes and different rotation directions, which can perform finer screening of slag and screen the slag into three different particle sizes. This means that the slag after being screened by this device does not need to be screened again, which greatly saves time and costs.

[0005] In actual screening, when the slag contains a large number of particles with a mesh size similar to the screen mesh, these particles are easy to get embedded in the mesh and cause blockage. However, when the rotary slag screening device is blocked, it usually needs to be stopped for cleaning, which will cause the screening equipment to be unable to operate continuously, thereby reducing production efficiency.

[0006] Therefore, it is necessary to provide a rotary slag screening device to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figures 1-2 As shown, this application provides a slag rotary screening device, including a base 1 and a screening mechanism 2 disposed on the upper end of the base 1. The screening mechanism 2 is used to perform rotary screening operation on slag.

[0039] The screening mechanism 2 includes mounting plates 20 fixedly mounted on both sides of the upper end of the base 1, and a rotating shaft 21 rotatably mounted between the two sets of mounting plates 20. One end of the rotating shaft 21 passes through one set of mounting plates 20, and a motor 22 is fixedly mounted on one side of the mounting plate 20. The output end of the motor 22 is fixedly connected to one end of the rotating shaft 21, so that starting the motor 22 can drive the rotating shaft 21 to rotate between the two sets of mounting plates 20.

[0040] In order to perform rotary screening of slag, a screen cage 23 is fixedly installed on the outside of the rotating shaft 21. The screen cage 23 has screen holes inside so as to separate slag particles of different sizes.

[0041] It should be noted that the screen cage 23 has openings on both sides and fits against the inner side of the mounting plates 20 at both ends to form a screening space and prevent slag from falling from the gap between the screen cage 23 and the mounting plates 20 during screening.

[0042] Meanwhile, a feed pipe 24 is provided on a set of mounting plates 20 away from the motor 22. The feed pipe 24 passes through the mounting plate 20 and communicates with the inside of the screen cage 23 so that the slag particles to be screened can be introduced into the screen cage 23. At the same time, a discharge port 26 is provided on another set of mounting plates 20. The discharge port 26 communicates with the inside of the screen cage 23 and is used to discharge larger slag particles or impurities after screening. It should be noted that the inside of the screen cage 23 is inclined and forms an inclined surface. The inclined surface gradually slopes downward along the direction from the feed pipe 24 to the discharge port 26 so that larger slag particles or impurities can be smoothly discharged through the inclined surface.

[0043] Meanwhile, in order to facilitate the screening operation, a cover 25 is fixedly installed between the two sets of mounting plates 20 on the outside of the screen cage 23, and a discharge port 27 is opened at the lower end of the cover 25 directly below the screen cage 23 to facilitate the discharge of smaller slag particles after screening.

[0044] When screening begins, the motor 22 can be started to drive the screen cage 23 to screen the slag particles. At this time, the slag particles are subjected to centrifugal force and gravity in the screen cage 23 and are separated into particles of different sizes. Smaller particles are discharged through the screen holes and the discharge port 27 directly below the screen cage 23, while larger particles or impurities remain in the screen cage 23. As the screen cage 23 continues to rotate, they are gradually pushed toward the discharge port 27 and discharged.

[0045] In order to clean the surface of the screen cage 23 without stopping the machine, thereby preventing the screen holes on the surface of the screen cage 23 from becoming clogged, such as Figure 1 and Figures 3-5 As shown, a cleaning mechanism 3 is provided on both sides of the cover 25. The cleaning mechanism 3 includes through holes 31 on both sides of the cover 25, and an arc plate 30 is hinged to the lower end of the through holes 31 on both sides of the cover 25. The size of the arc plate 30 is adapted to the size of the through holes 31, so that pushing the arc plate 30 can block the through holes 31. It can be understood that the arc plate 30 and the cover 25 are provided with matching holes, so that the arc plate 30 and the cover 25 can be fixed by fasteners to maintain the stability of the arc plate 30 when it blocks the through holes 31.

[0046] Meanwhile, a cleaning component 32 is provided on the arc plate 30. The cleaning component 32 includes a mounting base 320 fixedly installed on the outside of the arc plate 30, and a cylinder 321 is fixedly installed on the mounting base 320. The output end of the cylinder 321 passes through the arc plate 30 and is fixedly connected to a connecting plate 322. Thus, starting the cylinder 321 can drive the connecting plate 322 to move closer to or away from the screen cage 23.

[0047] Meanwhile, a slide groove 323 is provided on the connecting plate 322, and sliding seats 324 are slidably provided on both sides of the slide groove 323, so that the workers can push the sliding seats 324 on both sides to move on the slide groove 323. At the same time, a pin 325 is provided on the sliding seat 324, and multiple sets of positioning holes 326 are correspondingly provided on the slide groove 323. The positioning holes 326 are adapted to the pin 325 so that the sliding seat 324 can be fixed after being moved to a suitable position.

[0048] In order to smoothly clean the surface of the screen cage 23, a support block 327 is rotatably provided on the upper end of the sliding seat 324, and a brush cylinder 328 is fixedly provided between the two sets of support blocks 327 by fasteners. Multiple sets of soft bristles are fixedly provided on the brush cylinder 328 so as to clean the surface of the screen cage 23.

[0049] When it is necessary to clean the surface of the screen cage 23, simply start the cylinder 321 to push the brush cylinder 328 close to the surface of the screen cage 23 through the connecting plate 322 until the multiple sets of soft bristles on the outside of the brush cylinder 328 touch the surface of the screen cage 23 and then stop. At this time, the surface can be cleaned by the rotation of the screen cage 23 itself. When the cleaning is completed, simply start the cylinder 321 to drive the brush cylinder 328 away from the screen cage 23.

[0050] Meanwhile, when it is necessary to replace the brush cylinder 328, simply open the arc plate 30, unlock the pin 325, and the brush cylinder 328 will separate from the support block 327. Then, move the sliding seat 324 to remove the brush cylinder 328 for replacement.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
