Abstract

This utility model discloses a novel conveying device for transporting smelting slag, comprising a screw conveyor mechanism, a corner bend, and a straight pipe fitting. One end of the corner bend is connected to the discharge port of the screw conveyor mechanism, and the other end is connected to the straight pipe fitting. A rotating component is provided between the corner bend and the straight pipe fitting. One end of the rotating component has several equally spaced limiting blocks, each with an inner groove for locking the flange of the corner bend. A scraper and a sprocket ring are also provided at the rotating component. This utility model employs a rotating component design at the corner bend. The rotation drive mechanism drives the rotating component to rotate relative to the corner bend and the straight pipe fitting via the sprocket ring. As the rotating component rotates, the scraper scrapes the smelting slag deposited at the corner bend into the straight pipe fitting. Workers can clean the smelting slag deposited at the pipe junction without disassembling the pipe.

Description

Technical Field

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

[0002] The scientific recycling and resource utilization of smelting slag has profound economic, environmental, and social significance. Smelting slag contains valuable metals such as iron, copper, nickel, cobalt, and zinc. These metals can be extracted again through advanced recycling processes such as crushing, screening, magnetic separation, and gravity separation. Before crushing, the slag needs to be transported. Currently, screw conveyors combined with pipelines are mainly used for transporting smelting slag. During the transportation process, some slag tends to accumulate at the pipe junctions, requiring workers to periodically disassemble the pipes and clean the accumulated slag at these junctions. How to automatically clean the slag deposited at the pipe junctions has become a technical challenge. Therefore, we propose a novel conveying device for transporting smelting slag. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of conveying device for conveying smelting furnace slag.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A novel conveying device for conveying smelting slag, comprising a screw conveying mechanism, a corner bend, and a straight pipe fitting. One end of the corner bend is connected to the discharge port of the screw conveying mechanism, and the other end of the corner bend is connected to the straight pipe fitting. A rotating component is provided between the corner bend and the straight pipe fitting. One end of the rotating component is provided with several equally spaced limiting blocks. The limiting blocks are provided with an inner groove for locking the flange of the corner bend. A scraper is provided at the rotating component, and a sprocket ring is provided at the rotating component. A rotation drive mechanism drives the rotating component to rotate relative to the corner bend and the straight pipe fitting through the sprocket ring. When the rotating component rotates, the scraper scrapes the smelting slag deposited at the corner bend into the straight pipe fitting.

[0005] To further elaborate, the rotating component has a flared end and a straight end, the sprocket is disposed between the flared end and the straight end, the limiting block is installed at the end face of the flared end, and the straight end of the rotating component extends into the straight pipe.

[0006] To further elaborate, the straight opening of the rotating component has several outer annular grooves. These outer annular grooves are used to reduce the contact area between the straight opening of the rotating component and the inner wall of the straight pipe, thereby reducing the rotational friction between the rotating component and the straight pipe when the rotating component rotates.

[0007] To elaborate further, one end of the scraper is fixed to the inner wall of the flared opening of the rotating member, and the other end of the scraper extends outward from the flared opening of the rotating member.

[0008] To further elaborate, the rotary drive mechanism includes a drive motor, a drive sprocket, and a transmission chain. The drive sprocket is mounted on the output end of the drive motor, and the transmission chain is wound around the drive sprocket and the sprocket ring of the rotating component.

[0009] To elaborate further, the drive motor is fixedly installed on the frame of the screw conveyor mechanism.

[0010] To further elaborate, the spiral conveying mechanism includes an outer tube, inside which is a spiral impeller. The lower end of the outer tube has an inlet, and the outlet is located at the upper end of the outer tube.

[0011] The beneficial effects of this utility model are as follows: This utility model adopts a rotating component structure design at the corner bend. The rotating drive mechanism drives the rotating component to rotate relative to the corner bend and the straight pipe through the sprocket ring. When the rotating component rotates, the scraper scrapes the smelting slag deposited at the corner bend into the straight pipe. The workers can clean the smelting slag deposited at the pipe junction without disassembling the pipe. Attached Figure Description

One end of the corner bend 20 is connected to the discharge port 112 of the screw conveyor 10, and the other end of the corner bend 20 is connected to the straight pipe fitting 30. The smelting slag enters from the inlet 111 of the screw conveyor 10, and the screw conveyor 10 conveys the smelting slag upward. The smelting slag then enters the corner bend 20 from the discharge port 112 of the screw conveyor 10 and is transferred to the straight pipe fitting 30 via the corner bend 20.

[0019] Combined with appendix Figure 1 To be continued Figure 3 As shown, the screw conveyor mechanism 10 includes an outer tube 11, a screw impeller 12 is provided inside the outer tube 11, an inlet 111 is provided at the lower end of the outer tube 11, and an outlet 112 is provided at the upper end of the outer tube 11.

One end of the rotating component 41 is provided with several equally spaced limiting blocks 42, as shown in the attached figure. Figure 4 As shown, the limiting block 42 is provided with an inner groove 421 for locking the flange 21 of the corner bend 20. The rotating part 41 is provided with a scraper part 411 and a sprocket ring 412. The rotation drive mechanism 43 drives the rotating part 41 to rotate relative to the corner bend 20 and the straight pipe 30 through the sprocket ring 412. When the rotating part 41 rotates, the scraper part 411 scrapes the smelting slag deposited at the corner bend 20 into the straight pipe 30. The workers can clean the smelting slag deposited at the pipe junction without disassembling the pipe.

[0021] Combined with appendix Figure 2 and attached Figure 4 As shown, the rotating component 41 has a flared mouth portion 413 and a straight mouth portion 414. The sprocket ring 412 is located between the flared mouth portion 413 and the straight mouth portion 414. The limiting block 42 is installed at the end face of the flared mouth portion 413. The straight mouth portion 414 of the rotating component 41 extends into the straight pipe component 30.

[0022] The straight opening 414 of the rotating member 41 has several outer annular grooves 415. The outer annular grooves 415 are used to reduce the contact area between the straight opening 414 of the rotating member 41 and the inner wall of the straight pipe 30, thereby reducing the rotational friction between the rotating member 41 and the straight pipe 30 when rotating. One end of the scraper part 411 is fixed to the inner wall of the flared opening 413 of the rotating member 41, and the other end of the scraper part 411 extends outward from the flared opening 413 of the rotating member 41.

The drive sprocket 432 is mounted on the output end of the drive motor 431, and the transmission chain 433 is wound around the drive sprocket 432 and the sprocket ring 412 of the rotating component 41. The drive motor 431 is fixedly mounted on the frame 13 of the screw conveyor mechanism 10. The drive motor 431 drives the transmission chain 433 through the drive sprocket 432, and the transmission chain 433 drives the sprocket ring 412, thereby driving the rotating component 41 to rotate. When the rotating component 41 rotates, the scraper part 411 scrapes the smelting slag deposited at the corner bend 20 into the straight pipe component 30.
