Description

Technical Field

[0001] This utility model relates to the field of slag environmental protection technology, and in particular to a novel conveying device for conveying slag from a smelting furnace. Background Technology

[0002] A melting furnace is a device used for high-temperature heating and melting of metals, ores, or other materials, and is widely used in industries such as metallurgy, casting, and chemicals. Its main function is to convert solid metals or other raw materials into liquid metals through heating, preparing them for subsequent casting, refining, or other processing.

[0003] Slag formation is unavoidable during the smelting process in a melting furnace, primarily for the following reasons: During smelting, fluxes (such as lime and quartz) are typically added to remove impurities from the metal. These fluxes react with the impurities to form slag. Simultaneously, under high-temperature conditions, the metal may react with oxygen in the air to form metal oxides. These oxides cannot directly fuse with the metal in the melting furnace, thus forming slag. After smelting, slag treatment is also a crucial step. Current slag transportation methods, besides effectively removing slag from the melting furnace, often involve screening during transport because some slag contains unrefined, recyclable metal elements or mineral particles.

[0004] During the transportation and screening of slag, it is also necessary to consider the potential for blockage in equipment pipelines, screens, or other conveying components, which could affect the smooth operation of the entire process. Therefore, this design incorporates an anti-clogging mechanism for the screens that facilitates screening and transportation while ensuring synchronization. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A novel conveying device for conveying slag from a smelting furnace includes a frame with a horizontal cylinder at the top. The horizontal cylinder comprises an outer cylinder and an inner cylinder. An assembly space is provided between the outer cylinder and the inner cylinder. A feed hopper is connected to one side of the outer cylinder, and an opening is provided at the bottom of the outer cylinder. The feed hopper penetrates the outer cylinder and communicates with the interior of the inner cylinder. A screen is provided on the surface of the inner cylinder. Simultaneously, a motor unit is provided at the lower end of the outer side of the outer cylinder. The drive shaft of the motor unit extends through the outer cylinder to the bottom of the internal assembly space, and a drive gear is provided at the end of the drive shaft. A moving gear that meshes with the drive gear is provided on the outer surface of the inner cylinder. An anti-blocking mechanism is provided above the assembly space. The anti-blocking mechanism includes a rotating rod sleeved on the inner wall of the outer cylinder. A secondary gear that meshes with the moving gear is provided on the rotating rod, and a threaded transmission block is provided on the rotating rod. A brush is provided at the lower end of the transmission block.

[0007] Furthermore, above the assembly space, an assembly plate is provided on the inner wall of the outer cylinder. The rotating rod is sleeved and connected to the assembly plate, and the rotating rod passes through the assembly plate. A guide rod is also provided on the assembly plate, and a guide groove is provided on the transmission block and sleeved on the guide rod.

[0008] Furthermore, there are two sets of guide rods on the assembly plate, which are symmetrically distributed on both sides relative to the rotating rod, and the guide groove on the transmission block is set in two places corresponding to the guide rods.

[0009] Furthermore, the guide rod is hollow inside, and the lower end of the guide rod has a row of air holes. An air pump is installed on the upper part of the outer cylinder, and an air inlet is provided on the guide rod. An air pipe is connected between the air inlet and the air pump.

[0010] Furthermore, the air inlet of one set of guide rods is located on the left side, and the air inlet of the other set of guide rods is located on the right side.

[0011] Furthermore, the lower end of the outer cylinder is equipped with a collection bucket with an opening at the top.

[0012] Furthermore, a door is provided on the other side of the outer cylinder relative to the feed hopper.

[0013] The beneficial effects of this utility model are:

[0014] (1) In the process of transporting and collecting slag, the unrefined metal elements or mineral particles can be screened with the slag to separate the slag from the particulate matter, thereby achieving environmental protection and resource recovery.

[0015] (2) During screening, brushes can be used to clean the screen holes simultaneously. The use of brushes can effectively clean the accumulated material on the screen holes and prevent fine particles or adhering substances in the slag from clogging the screen holes.

[0016] (3) At the same time, the air blowing method is adopted to further clear the screen holes, which can effectively reduce the risk of screen hole blockage and ensure that the screening system can still maintain efficient operation during long-term operation.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1-2 This utility model includes a frame 1, with a horizontal cylindrical body at the upper end of the frame 1. The horizontal cylindrical body includes an outer cylindrical body 2 and an inner cylindrical body 3. An assembly space 4 is left between the outer cylindrical body 2 and the inner cylindrical body 3. A feeding hopper 5 is connected to one side of the outer cylindrical body 2, and an opening 6 is provided at the lower end of the outer cylindrical body 2. The feeding hopper 5 passes through the outer cylindrical body 2 and communicates with the interior of the inner cylindrical body 3. A sieve hole 7 is provided on the surface of the inner cylindrical body 3. At the same time, a motor unit 8 is provided at the lower end of the outer side of the outer cylindrical body 2, and the drive shaft of the motor unit 8 passes through the outer cylindrical body 2 and extends... Extending to the bottom of the internal assembly space 4, the motor unit 8 has a drive gear 9 at the end of its drive shaft, and a moving gear 10 that meshes with the drive gear 9 is provided on the outer surface of the inner cylinder 3; at the same time, an anti-blocking mechanism 11 is provided above the assembly space 4. The anti-blocking mechanism 11 includes a rotating rod 12 sleeved on the inner side wall of the outer cylinder 2, a secondary gear that meshes with the moving gear 10 is provided on the rotating rod 12, and a threaded transmission block 22 is provided on the rotating rod 12. A brush 13 is provided at the lower end of the transmission block 22.

[0023] The main technology of this equipment lies in its ability to screen, clean, and prevent clogging of materials through a reasonable mechanical structure design and movement method.

[0024] First, the frame 1, as the basic support structure, provides stability and load-bearing capacity for the entire device. It is mainly used to support the horizontal cylinder, the motor unit 8 on the horizontal cylinder, and other components, ensuring that each component can operate stably during operation.

[0025] For a horizontal cylindrical shell, it mainly consists of an outer cylinder 2 and an inner cylinder 3, forming two layers. The inner cylinder 3 has a sieve hole 7 on its surface. In the design of the outer cylinder 2, a feed hopper 5 is connected to one side. The feed hopper 5 is connected to the inner cavity of the inner cylinder 3 to allow slag from the smelting furnace to enter. After the slag is screened by the inner cylinder 3, the ash falls through the sieve hole 7 for collection and transportation in subsequent processes. Larger particles, such as incompletely refined metal elements or mineral particles, remain in the inner cavity of the inner cylinder 3, thus completing the screening purpose.

[0026] The screening process of this device is specifically achieved through an internally installed rotating assembly. An assembly space 4 is provided between the outer cylinder 2 and the inner cylinder 3. One end of the inner cylinder 3 is connected to the inner wall of the outer cylinder 2 away from the feed hopper 5 via a sleeve connection, or through gear meshing for a rotatable connection. To ensure stable rotation of the inner cylinder 3, the connection method can be a bushing connection, or precise assembly and meshing via a gear set. A moving gear 10 is provided on the outer surface of the inner cylinder 3 near the feed hopper 5. This moving gear 10, connected to a drive assembly, enables the rotation of the inner cylinder 3. The drive assembly includes a motor unit 8 installed on the lower side of the outer end of the outer cylinder 2. The drive shaft of the motor unit 8 passes through the outer cylinder 2, extends to the lower part of the internal assembly space 4, and a drive gear 9 is installed at the end of the drive shaft. Power is transmitted through the meshing of the drive gear 9 with the moving gear 10 on the inner cylinder 3, causing the inner cylinder 3 to rotate during the screening process. The rotation of the inner cylinder 3 plays a crucial role in the screening of materials. During rotation, slag or other materials inside the inner cylinder 3 are driven upwards and then fall downwards along the inner cylinder 3 under the influence of gravity. This rotation not only promotes material flow but also accelerates the removal of large particles, improving screening efficiency. To enhance screening effectiveness and prevent material from stagnating inside the inner cylinder 3 during rotation, protruding blocks can be spaced inside the inner cylinder 3. These protruding blocks, through friction with the material, further propel the slag to a higher position along the inner cylinder 3, enhancing material movement and ensuring uniform screening and effective removal. This makes the entire screening process more efficient, effectively reduces clogging, and improves the overall operational stability and screening quality of the device.

[0027] Based on the aforementioned rotation of the inner cylinder 3, an anti-blocking mechanism 11 is provided above the assembly space 4. The anti-blocking mechanism 11 includes a rotating rod 12 sleeved on the inner wall of the outer cylinder 2. The rotating rod 12 is provided with a secondary gear that meshes with the moving gear 10, and a threaded transmission block 22 is provided on the rotating rod 12. A brush 13 is provided at the lower end of the transmission block 22. Specifically, an assembly plate 14 is provided on the inner wall of the outer cylinder 2 above the assembly space 4. The rotating rod 12 is sleeved and connected to the assembly plate 14, and the rotating rod 12 passes through the assembly plate 14. A guide rod 15 is also provided on the assembly plate 14. A guide groove 16 is provided on the transmission block 22 and sleeved on the guide rod 15. There are two sets of guide rods 15 on the assembly plate 14, which are symmetrically distributed on both sides relative to the rotating rod 12. The guide groove 16 on the transmission block 22 is provided at two locations corresponding to the guide rods 15.

[0028] Above the assembly space 4, the core component of the anti-clogging mechanism 11 is a rotating rod 12, which is sleeved and connected to the inner wall of the outer cylinder 2. The rotating rod 12 is used to achieve rotation, and it is equipped with a secondary gear, which meshes with the moving gear 10 on the inner cylinder 3. This means that when the inner cylinder 3 rotates, the moving gear 10 drives the secondary gear to rotate, thereby driving the rotating rod 12 to rotate. The rotating rod 12 is also equipped with a transmission block 22 connected by a threaded drive, and a brush 13 is mounted on the lower end of the transmission block 22. By rotating the rotating rod 12, the secondary gear drives the transmission block 22 to move along the threaded path, thereby realizing the up-and-down or back-and-forth movement of the transmission block 22. The brush 13 is connected to the transmission block 22, and with the help of the movement of the transmission block 22, the brush 13 cleans along the surface inside the device to prevent material accumulation. Another important component of the anti-clogging mechanism 11 is the assembly plate 14. The assembly plate 14 is fixed above the outer cylinder 2, and its inner wall is equipped with a guide rod 15. The function of the guide rod 15 is to ensure that the transmission block 22 moves along the correct track during operation, preventing instability or blockage caused by deviation from the track. The guide rods 15 on the assembly plate 14 are designed in two sets, symmetrically distributed on both sides of the rotating rod 12. This design ensures that the transmission block 22 moves evenly along the path of the guide rods 15 on both sides, avoiding unbalanced movement due to excessive load on one side. The brush 13, connected to the transmission block 22, cleans the inner surface of the assembly space 4 between the inner cylinder 3 and the outer cylinder 2. Driven by the transmission block 22, the brush 13 effectively removes accumulated material from the surface, especially preventing blockage caused by material accumulation. The working principle is as follows: when the inner cylinder 3 rotates, the moving gear 10 drives the secondary gear to rotate, which in turn drives the rotating rod 12 to rotate. The transmission block 22 on the rotating rod 12 moves along the threaded track, driving the lower brush 13 to clean the inner surface of the assembly space 4. The guide rod 15 ensures the stable movement of the transmission block 22 and prevents malfunctions or blockages caused by uneven movement.

[0029] Meanwhile, in order to further clear the screen holes 7, the guide rod 15 is hollow inside, and the lower end of the guide rod 15 is provided with a row of air holes 17. The upper end of the outer cylinder 2 is provided with an air pump 18, and the guide rod 15 is provided with an air inlet 19. An air pipe 20 is connected between the air inlet 19 and the air pump 18. One set of air inlets 19 of the guide rod 15 is located on the left side, and the other set of air inlets 19 of the guide rod 15 is located on the right side.

[0030] The guide rod 15 is hollow inside, providing an airflow channel that allows gas to be transferred from the outside to the inside. This design enables airflow to flow effectively into the lower end of the guide rod 15 and exit through the air hole 17, thus helping to clear the screen holes 7. An air pump 18 is located at the upper end of the outer cylinder 2. The air pump 18 provides the air source and transmits the gas to the air inlet 19 of the guide rod 15 through the connected air pipe 20. The airflow generated by the air pump 18 is introduced into the guide rod 15 through the air pipe 20 and enters the interior of the guide rod 15 through the air inlet 19. After flowing inside the guide rod 15, the gas exits from the air hole 17 at the lower end of the guide rod 15. A row of air holes 17 is arranged at the lower end of the guide rod 15, which can evenly spray the airflow into the area of ​​the screen holes 7 around the guide rod 15. After being sprayed out through these air holes 17, the airflow acts on the surface of the screen holes 7 or the material surface, generating an airflow impact force that effectively helps to clear screen holes 7 that may be blocked by material. To ensure more even airflow through the screen holes 7, the air inlets 19 are designed with symmetry in mind. One set of air inlets 19 on the guide rods 15 is located on the left, and the other set on the right. This allows for a more uniform distribution of airflow across the screen hole 7 area, improving the unblocking effect and preventing insufficient airflow from affecting one side of the screen holes 7. The working principle is as follows: When the air pump 18 starts, it delivers airflow through the air pipe 20 to the air inlets 19 of the guide rods 15. After entering the guide rods 15, the gas flows along its hollow interior and is finally discharged through the lower air hole 17. The jetting effect of the airflow creates an impact force on the screen hole 7 area, effectively unblocking the screen holes 7 and ensuring a smooth screening process. This airflow action prevents material from accumulating or clogging in the screen holes 7, further improving the equipment's operating efficiency and screening accuracy.

[0031] The outer cylinder 2 has a collection bucket 21 with an upper opening 6 at the lower end for collecting slag and dust, while large metal particles remain inside the inner cylinder 3. A door is provided on the other side of the outer cylinder 2 opposite to the feed hopper 5. By opening the door, large metal particles and other materials remaining inside can be discharged periodically.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
