Description

Technical Field

[0001] The utility model relates to the technical field of phosphorus slag cleaning, in particular to a yellow phosphorus electric furnace phosphorus slag cleaning device. Background Art

[0002] Phosphorus slag is one of the main by-products of industrial yellow phosphorus. Usually, for every ton of yellow phosphorus produced, about 10 tons of phosphorus slag will be produced. Phosphorus slag is usually used as raw material for silicate cement, white carbon black, slag bricks and other fields.

[0003] The electric furnace in the yellow phosphorus workshop is unloaded every two hours, requiring a large amount of slag flushing water to extract and cool the hot, molten slag. The phosphorus slag is typically dehydrated in a dehydrator and transported by belt conveyor to a slag bin for loading and shipping. A small amount of slag adheres to the conveyor belt. After the belt passes over the electric roller, the fine slag particles fall under gravity onto the support below the belt. This results in a large amount of slag accumulating over time in the slag steam field and on the belt support, making cleanup a heavy workload and difficult on-site management. Summary of the Invention

[0004] The technical problem to be solved by the utility model is that the slag adheres to the conveying belt during the conveying process and is difficult to clean.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a yellow phosphorus electric furnace phosphorus slag cleaning device, including a mounting frame, a conveying roller of a conveyor belt is rotatably mounted on the mounting frame, a collecting hopper is installed at the bottom of the mounting frame, a scraper is installed at the top of the mounting frame, the movable end of the scraper abuts against the conveyor belt, a brush rod and a spray pipe are installed on the top of the collecting hopper, and the brush rod is located downstream of the spray pipe along the rotation direction of the conveyor belt.

[0006] Preferably, the scraper is arranged at an angle, the thickness of the movable end of the scraper is smaller than the thickness of the fixed end, and a scraper notch is provided on the top of the mounting frame, and the scraper notch is located on the side of the scraper away from the conveyor belt.

[0007] Preferably, the end of the scraper is fixedly connected to a reinforcing plate with a triangular structure, and is connected to the mounting frame through the reinforcing plate.

[0008] Preferably, a driving device is installed on the top of the collecting hopper, the brush rod is rotatably arranged, the output end of the driving device is coaxially fixedly connected to one end of the brush rod, and the top of the brush rod contacts the conveyor belt located below the conveyor roller.

[0009] Preferably, the spray pipe is arranged horizontally, and is provided with a top nozzle and a bottom nozzle. The top nozzle and the bottom nozzle are equidistantly arranged along the axial direction of the spray pipe, the top nozzle faces the conveyor belt, and the bottom nozzle faces the bottom of the brush rod.

[0010] Preferably, a phosphorus slag storage conveyor belt is provided just below the discharge port at the bottom of the collecting hopper.

[0011] The utility model provides a yellow phosphorus electric furnace phosphorus slag cleaning device. During the rotation of the conveyor belt, the device shovels off the phosphorus slag attached to the conveyor belt through the collision of a scraper with the phosphorus slag on the conveyor belt, and part of the phosphorus slag falls into a collecting hopper. Then, the surface of the conveyor belt is scrubbed by a brush rod. After scrubbing, high-pressure flushing is performed through a spray pipe, and the residual phosphorus slag adhered to the belt is flushed into the collecting hopper by high-pressure water. Finally, the phosphorus slag is conveyed to the slag bin through a phosphorus slag silo conveyor belt, thereby realizing automatic cleaning and collection of the phosphorus slag on the conveyor belt, improving the working site, reducing the labor intensity of cleaning the site, and improving the site management level.

[0016] like Figure 1 and Figure 2 The utility model provides a yellow phosphorus electric furnace phosphorus slag cleaning device, comprising a mounting frame 3, a conveyor roller 1 of a conveyor belt 2 rotatably mounted on the mounting frame 3, a collecting hopper 7 mounted at the bottom of the mounting frame 3, a scraper 4 mounted at the top of the mounting frame 3, the movable end of the scraper 4 abutting against the conveyor belt 2, a brush rod 6 and a spray pipe 9 mounted at the top of the collecting hopper 7, and the brush rod 6 located downstream of the spray pipe 9 along the rotation direction of the conveyor belt 2.

[0017] The conveyor roller 1 is used to support the rotation of the conveyor belt 2. The conveyor roller 1 is installed for rotation through the mounting frame 3. During the rotation of the conveyor belt 2, when the conveyor belt 2 moves to the scraper 4, the movable end of the scraper 4 contacts the surface of the conveyor belt 2. The scraper 4 scrapes off the phosphorus slag attached to the surface of the conveyor belt 2, so that the block phosphorus slag on the surface of the conveyor belt 2 falls into the collecting hopper 7. As the conveyor belt 2 rotates further, the brush rod 6 brushes the small phosphorus slag and phosphorus slag marks on the surface of the conveyor belt 2, so that the small phosphorus slag is brushed off and enters the collecting hopper 7. Finally, the surface of the conveyor belt 2 is high-pressure washed through the spray pipe 9, so that the small phosphorus slag and phosphorus slag marks on the surface of the conveyor belt 2 are washed clean and enter the collecting hopper 7. The phosphorus slag in the collecting hopper 7 falls from the lower end opening, and the phosphorus slag discharged from the collecting hopper 7 is conveyed to the slag bin through the phosphorus slag inlet conveyor belt.

[0018] like Figure 1 As shown, the scraper 4 is tilted, with the movable end of the scraper 4 being thinner than the fixed end. A scraping notch is provided at the top of the mounting frame 3, located on the side of the scraper 4 away from the conveyor belt 2. The tilted arrangement of the scraper 4 improves the sharpness of its end, making it easier to scrape phosphorus slag off the conveyor belt 2. The fallen phosphorus slag, guided by the scraper 4, falls through the scraping notch into the collection hopper 7.

[0019] like Figure 1 As shown, in order to improve the installation strength of the scraper 4 and avoid deformation and displacement of the scraper 4 during long-term operation, the end of the scraper 4 is fixedly connected to a triangular reinforcing plate 5, and is connected to the mounting frame 3 through the reinforcing plate 5.

[0020] As a preferred embodiment of the present invention, a drive device is mounted on top of the collection hopper 7, and the brush rod 6 is rotatably mounted. The output end of the drive device is coaxially fixedly connected to one end of the brush rod 6, and the top of the brush rod 6 contacts the conveyor belt 2 located below the conveyor roller 1. The drive device includes a motor and a reducer. The speed of the active end of the drive device is adjusted according to the amount of phosphorus slag attached to the conveyor belt 2. This rotation drives the brush rod 6, which then scrubs the surface of the conveyor belt 2.

[0021] like Figure 1 and Figure 2As shown, the spray pipe 9 is arranged horizontally and is equipped with a top nozzle 10 and a bottom nozzle 11. The top nozzles 10 and 11 are equidistantly spaced along the axial direction of the spray pipe 9. The top nozzle 10 faces the conveyor belt 2, while the bottom nozzle 11 faces the bottom of the brush rod 6. The spray pipe 9 is connected to and supplied with water via a mounting pipe 8. The mounting pipe 8 and the spray pipe 9 are both fixedly mounted on the top of the collection hopper 7. The top nozzle 10 is used to flush the conveyor belt 2, and the bottom nozzle 11 is used to flush the bottom of the brush rod 6, flushing any phosphorus slag stuck on the brush rod 6 into the collection hopper 7.

[0022] As a preferred embodiment of the present invention, a phosphorus slag inlet conveyor belt is disposed directly below the discharge port at the bottom end of the collection hopper 7. The phosphorus slag inlet conveyor belt transports the phosphorus slag falling from the collection hopper 7 to the slag bin. The phosphorus slag inlet conveyor belt is tilted, and water falling from the collection hopper 7 flows down from the bottom end of the phosphorus slag inlet conveyor belt.
