Description

Technical Field

[0001] This utility model belongs to the field of slag production technology, specifically a screening device for slag production and processing. Background Technology

[0002] Also known as slag, it is a melt that floats on the surface of liquid substances such as metals during pyrometallurgical processes. Its composition is mainly oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and it often contains sulfides and a small amount of metal. In existing slag screening, the metal in the slag is generally separated by metal valves. This method can easily lead to large metal blockages in pipes or metal valves, resulting in resource waste. Therefore, we propose a screening device for slag production and processing. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A screening device for slag production and processing includes a screening device 100 and a metal removal device 200. The screening device 100 includes a first frame 110, with a filter tube 120 connected to the upper side of the first frame 110. The filter tube 120 has multiple sets of filter holes and is inclined. First gears 130 are provided on both the left and right sides of the first frame 110, and second gears 140 are fixedly connected to both the left and right sides of the filter tube 120. The first gears 130 and second gears 140 mesh with each other. First rotating rods 150 are fixedly connected to the inner walls of the two sets of first gears 130. A first motor 160 is fixedly installed on the left side of the first frame 110, and the transmission end of the first motor 160 is fixedly connected to the first rotating rod 150. When the device is in use, slag enters the filter tube 120 from the right side. The first motor 160 is started, driving the first rotating rod 150 to rotate. The rotation drives the first gear 130 to rotate, which in turn drives the second gear 140 to rotate, which in turn drives the filter tube 120 to rotate. The rotation of the filter tube 120 causes the slag to tumble, allowing it to be filtered within the filter tube 120. Large pieces of slag are discharged from the left side of the filter tube 120, while the remaining slag is discharged through the filter holes. The screening device 100 filters large pieces of slag, allowing for further crushing and preventing them from affecting subsequent processing and recycling. A guide pipe 201, funnel-shaped, is fixedly connected to the upper side of the metal removal device 200. The slag discharged from the filter holes of the filter tube 120 is guided into the metal removal device 200 through the guide pipe 201. The guide pipe 201 facilitates the guidance of the slag, ensuring it enters the metal removal device 200.

[0022] The metal rejection device 200 is located below the screening device 100. The metal rejection device 200 includes a belt conveyor 210. A second support 220 is connected to the upper side of the belt conveyor 210. A second rotating rod 230, a third rotating rod 240, and a fourth rotating rod 250 are arranged on the upper side of the second support 220. A second motor 260 is fixedly installed on the right side of the second support 220. The transmission end of the second motor 260 is fixedly connected to the fourth rotating rod 250. A rubber conveyor belt 270 is arranged on the outer side of the second rotating rod 230, the third rotating rod 240, and the fourth rotating rod 250. The interior of the rubber conveyor belt 270 is... An electromagnetic strip 271 is installed. When the second motor 260 is started, it drives the fourth rotating rod 250 to rotate. The rotation of the fourth rotating rod 250 drives the rubber conveyor belt 270 to rotate. The rotation of the rubber conveyor belt 270 drives the electromagnetic strip 271 to adsorb slag falling onto the belt conveyor 210. A metal removal device 200 is installed to adsorb metal objects in the slag using the electromagnetic strip 271, thereby improving the efficiency of item recycling, increasing waste utilization efficiency, and reducing economic losses. A cylinder 211 is fixedly installed on the upper side of the belt conveyor 210. The telescopic end of 211 is fixedly connected to a lever 212. A cylinder 211 drives the lever 212 to move left and right, thus spreading the slag placed on the belt conveyor 210, thereby improving the efficiency of subsequent metal removal. It is worth mentioning that the electromagnetic strip 271 uses contact power supply. When the electromagnetic strip 271 moves to the vicinity of the rear unloading area, the power is cut off, thus eliminating the magnetic force and causing it to adhere to the rubber conveyor belt. Metal outside 270 falls onto the unloading plate and is guided by the unloading plate or manually discharged by the operator. Two sets of first linear guide rails 231 and a second rotating rod 2 are fixedly installed on the upper side of the second bracket 220. The left and right sides of the second rotating rod 230 are respectively connected to two sets of first linear guide rails 231. By setting the first linear guide rails 231, the height of the second rotating rod 230 can be adjusted, thus providing sufficient space for the slag to move when dealing with different types of slag. The upper side of the second support 220 is provided with two sets of second linear guide rails 241. The left and right sides of the third rotating rod 240 are respectively connected to two sets of second linear guide rails 241. By setting the second linear guide rails 241, the third rotating rod 240 is driven to move back and forth, thus keeping the rubber conveyor belt 270 in a taut state and improving the stability of the device.
