Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag processing, and in particular to a slag residual fine powder air separation component. Background Technology
[0002] A slag residue fine powder air classifier is a device used in slag processing to separate and screen residual fine powder from slag. Slag is a byproduct of blast furnace ironmaking. During ironmaking, impurities in iron ore react with lime and other substances to form a molten material, which, after quenching, becomes a loose, porous granular material—blast furnace slag. In the recycling of slag, it is necessary to separate the fine powder from it.
[0003] In the air separation chamber, when high-speed airflow enters, fine powder particles are small in size and light in weight, so the force exerted by the airflow on them is greater than that of gravity. Therefore, the fine powder will move towards the upper part or outlet of the air separation chamber under the influence of the airflow. Meanwhile, coarse particles are large in size and heavy in weight, so the airflow cannot provide enough force to suspend them. Gravity takes precedence, so the coarse particles will settle towards the lower part or bottom of the air separation chamber, thus achieving the separation of fine powder and coarse particles.
[0004] Slag residues usually contain a certain amount of moisture. When the humidity is high, fine powder particles are prone to agglomerate due to the surface tension of the moisture, making it difficult to effectively separate fine powder from coarse particles. This reduces the accuracy and efficiency of air classification. During air classification, because fine powder particles are small in size and light in weight, the force exerted by the airflow on them is greater than that of gravity. Therefore, the fine powder will move towards the outlet direction under the influence of the airflow. However, the accuracy of air classification is low and it cannot achieve precise classification of coarse and fine particles. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through its ingenious structural design, uses an electric heating element to transfer heat to the slag residue inside the feed box via a cavity. Starting the motor rotates the stirring blades, continuously agitating the slag within the feed box. This ensures the fine slag powder is evenly heated by the heating element, improving drying efficiency and breaking up clumps of slag while maintaining the loose powder. Starting the motor also rotates a cam, which exerts a downward thrust on the striking column, causing it to rotate downwards around a pivot point on the mounting frame. Simultaneously, a spring is stretched. As the cam continues to rotate, its protruding part gradually moves away from the striking column, and the spring pulls the striking column upwards rapidly around the pivot point. This strikes the filter plate, dislodging slag impurities and preventing clogging. This avoids increased energy consumption due to clogging and contributes to energy conservation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1-3 This utility model provides an embodiment of a slag residue fine powder air classification component, including an air classification box 101, electric heating tubes 107, and a drying component. A support plate 102 is fixedly connected to one side of the air classification box 101, a support leg 103 is fixedly connected above the support plate 102, a feed box 104 is fixedly connected above the support leg 103, a feed inlet 105 is provided above the feed box 104, a drying component is provided inside the feed box 104, a cavity 106 is provided at the bottom of the feed box 104, multiple sets of electric heating tubes 107 are provided inside the cavity 106, a connecting frame 108 is fixedly connected to the outside of the feed box 104, a motor 109 is provided on one side of the connecting frame 108, a rotating rod 110 is provided inside the feed box 104, and the output end of the motor 109 is connected to the rotating rod 110. The sides are interconnected, and multiple sets of stirring blades 111 are fixedly connected above the rotating rod 110. The slag residue is transported into the feed box 104 through the feed inlet 105. The electric heating tube 107 heats the slag residue inside the feed box 104 through the cavity 106, which is made of iron and has good thermal conductivity. The rotating rod 110 is driven to rotate by the starting motor 109. The rotation of the rotating rod 110 causes the stirring blades 111 to rotate, thereby continuously agitating the slag inside the feed box 104. This ensures that the fine slag powder is evenly heated by the electric heating tube 107, improving the drying effect and efficiency, ensuring the drying quality, and breaking up clumps of slag to keep the fine powder loose. The feed box 104 is a closed environment during operation to prevent slag dust from polluting the working environment.
[0025] Please see Figures 2-5In this embodiment, a connecting frame 112 is fixedly connected to the outside of the feed box 104. A motor 201 is installed on one side of the connecting frame 112. A discharge cylinder 113 is installed below the feed box 104. A rotating rod 202 is installed inside the discharge cylinder 113. The output end of the motor 201 is connected to one side of the rotating rod 202. A spiral blade 203 is fixedly connected above the rotating rod 202. A transport pipe 204 is fixedly connected below the discharge cylinder 113. The transport pipe 204 is fixedly connected to the air classifier 101. A filter plate 205 is fixedly connected inside the air classifier 101 and is located above the bottom end of the transport pipe 204. A coarse particle discharge port 206 is installed below the air classifier 101. An inclined plate 207 is installed inside the air classifier 101, and the inclined surface of the inclined plate 207 is inclined towards the coarse particle discharge port 206. An air inlet pipe 208 is fixedly connected to one side of the discharge port 206, and a blower 209 is installed on the other side of the air inlet pipe 208. The motor 201 is started to drive the rotating rod 202 to rotate. The rotation of the rotating rod 202 drives the spiral blade 203 to rotate, thereby stably transporting the slag inside the feed box 104 to the air classifier 101. The coarse particles in the slag entering the air classifier 101 are discharged to the outside of the device through the coarse particle discharge port 206 due to their heavy mass. At the same time as the coarse particles are discharged, the blower 209 is started to transport the airflow through the air inlet pipe 208 to the inside of the coarse particle discharge port 206. The airflow is transported to the inside of the air classifier 101 through the coarse particle discharge port 206. Due to the influence of the airflow, the fine particles move with the direction of the airflow and can pass through the filter plate 205 to enter other areas of the air classifier 101, thereby achieving the separation of coarse and fine particles.
[0026] Please see Figures 4-6In this embodiment, a connecting frame 210 is fixedly connected to one side of the air classifier box 101, and a motor 211 is installed on one side of the connecting frame 210. A rotating rod 301 is installed inside the air classifier box 101. The output end of the motor 211 is connected to one side of the rotating rod 301. A cam 302 is fixedly connected above the rotating rod 301. A mounting frame 303 is fixedly connected inside the air classifier box 101. A striking column 304 is rotatably connected to one side of the mounting frame 303. A spring 305 is fixedly connected above the striking column 304. The other side of the spring 305 is fixedly connected to the filter plate 205. The rotating rod 301 is rotated by starting the motor 211. The rotation of the rotating rod 301 drives the cam 302 to rotate, and the cam 302 exerts a downward thrust on the striking column 304, causing the striking column 304 to rotate downward around the rotation point on the mounting bracket 303. At the same time, the spring 305 is stretched. As the cam 302 continues to rotate, the protruding part of the cam 302 gradually moves away from the striking column 304. Through the action of the spring 305, the striking column 304 is pulled upward rapidly around the rotation point, thereby striking the filter plate 205 and causing the slag and impurities attached to the filter plate 205 to fall off, preventing the pores of the filter plate 205 from becoming clogged. A support plate 306 is fixedly connected to one side of the air classifier box 101. The air classifier box 101 and the support plate 306 are connected. A second support leg 307 is fixedly connected to the bottom of the air classifier 101. A third support leg 308 is fixedly connected to the top of the second support plate 306. A filter box 309 is fixedly connected to the top of the third support leg 308. A fine particle outlet 401 is provided above the air classifier 101. The other side of the fine particle outlet 401 is fixedly connected to the filter box 309. A second filter plate 402 is provided inside the filter box 309. An air outlet duct 403 is provided on one side of the filter box 309. A second fan 404 is provided on the other side of the air outlet duct 403. The fine particles separated by the air classifier 101 enter the fine particle outlet 401 through the airflow. The fine particles are transported to the filter box 309 through the fine particle outlet 401. The filter plate 402 inside filter box 9 separates the incoming slag powder from the air. The blower 404 is started, creating a negative pressure in the air outlet duct 403, which draws out the air filtered by the filter plate 402 from filter box 309. The air pressure in filter box 309 is lower than the pressure in air classifier 101, allowing the airflow in air classifier 101 to continuously push fine slag particles into filter box 309 through fine particle outlet 401, forming a continuous airflow circulation. This ensures that the fine slag particles can be successfully collected into filter box 309, enabling the slag powder to be separated and collected under the action of airflow. At the same time, it ensures that the discharged air reaches a certain level of cleanliness, reducing environmental pollution.
[0027] During operation, slag residue is transported into the feed box 104 through the feed inlet 105. Heat is transferred to the slag residue inside the feed box 104 via the heating element 107, which is made of iron and has good thermal conductivity. The motor 109 drives the rotating rod 110 to rotate, which in turn rotates the stirring blades 111. This continuously agitates the slag inside the feed box 104, ensuring that the fine slag powder is evenly heated by the heating element 107, improving drying effect and efficiency, ensuring drying quality, and breaking up clumps of slag to maintain the looseness of the fine powder. The feed box 104 is a closed environment during operation, preventing slag dust from contaminating the working environment. When the slag is discharged, the motor 201 is started, driving the rotating rod 202 to rotate. The rotating rod 202 drives the spiral blades 203 to rotate, thus stably transporting the slag inside the feed box 104 to the air classifier 101. The coarse particles in the slag entering the air classifier 101, due to their greater weight, are discharged to the outside of the device through the coarse particle outlet 206. Simultaneously, the blower 209 is started, causing airflow to be transported through the air inlet pipe 208 to the interior of the coarse particle outlet 206. The airflow is then transported into the air classifier 101. Due to the influence of the airflow, the fine particles move in the direction of the airflow and can pass through the filter plate 205 to enter other areas of the air classifier 101, thus achieving the separation of coarse and fine particles. The separation of fine particles is achieved by starting the motor 3211, which drives the rotating rod 301 to rotate. The rotation of the rotating rod 301 drives the cam 302 to rotate, which in turn exerts a downward thrust on the striking column 304. This causes the striking column 304 to rotate downwards around the rotating point on the mounting bracket 303, simultaneously stretching the spring 305. As the cam 302 continues to rotate, its protruding part gradually moves away from the striking column 304. The spring 305 then pulls the striking column 304 upwards rapidly around the rotating point, thus striking the filter plate 205. This causes the slag and impurities adhering to the filter plate 205 to fall off, preventing clogging of the pores of the filter plate 205. The fine particles separated by the air separator 101 enter the fine particle outlet 40 through the airflow. In step 1, fine particles are transported to the filter box 309 through the fine particle outlet 401. The filter plate 402 inside the filter box 309 separates the incoming slag powder from the air. The blower 404 is activated, creating a negative pressure in the air outlet duct 403. This draws out the air filtered by the filter plate 402 from the filter box 309. The air pressure inside the filter box 309 is lower than the pressure inside the air classifier 101, allowing the airflow in the air classifier 101 to continuously force the fine slag particles into the filter box 309 through the fine particle outlet 401, forming a continuous airflow circulation. This ensures that the fine slag particles are successfully collected into the filter box 309, enabling the slag powder to be separated and collected under the action of airflow, while simultaneously ensuring that the emitted air reaches a certain level of cleanliness.Reduce environmental pollution.
[0028] Through the above steps, the slag residue is transported into the feed box 104 through the feed inlet 105. The electric heating tube 107 generates heat, which is then conducted through the cavity 106 to the slag residue inside the feed box 104. The cavity 106 is made of iron and has good thermal conductivity. The motor 109 drives the rotating rod 110 to rotate, which in turn causes the stirring blades 111 to rotate. This continuously agitates the slag inside the feed box 104, ensuring that the fine slag powder is evenly heated by the electric heating tube 107, improving the drying effect and efficiency, ensuring drying quality, and breaking up any clumps of slag to keep the fine powder loose. The feed box 104 is a closed environment during operation, preventing slag dust from polluting the working environment.
