Description

Technical Field

[0001] This utility model relates to the field of carbon black dust recovery technology, specifically a mechanism capable of cleaning and recovering carbon black adhering to the inner wall of a carbon black dust collection pipeline online. Background Technology

[0002] The carbon black production process generates a significant amount of carbon black dust. To prevent environmental pollution, this dust needs to be recycled. During the dust recycling process, the carbon black dust is carried by the airflow and impacts the inner wall of the carbon black dust collection pipe, easily forming clumps that adhere to the pipe walls. Current technology requires shutting down the machine for cleaning these clumps, disrupting normal carbon black production. Furthermore, the cleaning process is time-consuming, labor-intensive, and can easily cause secondary pollution to the surrounding environment. Summary of the Invention

[0003] In order to solve the problem that the existing technology requires stopping the machine to clean the carbon black hanging on the wall when processing it, which is not only time-consuming and labor-intensive, but also easy to cause secondary pollution to the surrounding environment, this utility model provides a mechanism that can clean and recycle the carbon black hanging on the wall in the carbon black dust collection pipeline online.

[0004] This utility model is achieved using the following technical solution:

[0005] A mechanism for online cleaning and recycling of carbon black adhering to the walls of a carbon black suction pipeline includes a collection device for collecting carbon black, a suction fan, and a carbon black suction pipeline. The carbon black suction pipeline is vertically arranged, with its top port connected to the inlet of the suction fan and its outlet connected to the collection device. The carbon black suction pipeline also has at least one carbon black dust inlet. A cylindrical pulverizing chamber is coaxially sealed and fixed at the bottom port of the carbon black suction pipeline. A coaxially arranged pulverizing motor is connected to the bottom port of the pulverizing chamber via a flange (as is known to those skilled in the art, this flange is the motor flange on the pulverizing motor, and the bottom port of the pulverizing chamber has a connecting flange, with the motor flange and the connecting flange adapted to form a flange connection structure). The shaft of the pulverizing motor extends into the pulverizing chamber, and multiple pulverizing blades are circumferentially distributed on the shaft of the pulverizing motor. Multiple compressed air ports are provided on the bottom circumferential wall of the pulverizing chamber, and the height of the multiple compressed air ports is lower than the height of the pulverizing blades. Each compressed air port is provided with a compressed air pipe arranged along the tangential direction of the pulverizing chamber.

[0006] In operation, carbon black dust generated during carbon black production is fed into the carbon black dust collection pipeline through a carbon black dust inlet. Compressed air is introduced into each compressed air pipe. When it is necessary to treat the carbon black adhering to the walls of the carbon black dust collection pipeline, the crushing motor is started, and the carbon black dust collection pipeline is manually tapped. The carbon black adhering to the walls of the carbon black dust collection pipeline falls into the crushing chamber. The shaft of the crushing motor rotates, driving the crushing blades on it to rotate. The crushing blades crush the fallen carbon black adhering to the walls. At the same time, multiple compressed air pipes blow smaller pieces of carbon black that have not been completely crushed around the crushing chamber toward the crushing blade area for further crushing, thereby improving the crushing efficiency of the carbon black adhering to the walls. The crushed carbon black pieces become carbon black dust, which is then blown up by the compressed air and sucked into the collection device by the dust collector through the carbon black dust collection pipeline. This achieves online cleaning and recycling of the carbon black adhering to the walls of the carbon black dust collection pipeline, reducing the labor intensity of operators and avoiding secondary pollution to the environment during the carbon black cleaning process.

[0007] Furthermore, the bottom port of the carbon black dust collection pipeline is connected to the top port of the crushing chamber via a butterfly valve. When the crushing chamber, crushing motor, or crushing blades require maintenance or replacement, they can be discharged online by closing the butterfly valve, without affecting the normal operation of the carbon black production line.

[0008] Furthermore, the pulverizing chamber includes an upper chamber, a transition chamber, and a lower chamber, all coaxially arranged with the carbon black dust collection pipeline. Both the upper and lower chambers are cylindrical. The diameter of the upper chamber is equal to the diameter of the carbon black dust collection pipeline. The transition chamber is a frustum-shaped cylinder. The pulverizing blade is located in the lower chamber, and the distance between the pulverizing blade and the shaft of the pulverizing motor is equal to the radius of the upper chamber. The pulverizing chamber is designed with a tapered shape at the top and a wider shape at the bottom to ensure that as much carbon black adhering to the walls of the carbon black dust collection pipeline as possible falls onto the pulverizing blade, improving pulverizing efficiency.

[0009] Furthermore, the shredder has four blades arranged in a cross shape, making the structure more specific and standardized.

[0010] Furthermore, there are three compressed air ports and three compressed air pipes.

[0011] The beneficial effects of this utility model are as follows: 1) The mechanism described in this utility model realizes the online cleaning and recycling of carbon black adhering to the wall inside the carbon black dust collection pipeline, reducing the labor intensity of operators and avoiding secondary pollution to the environment during the carbon black cleaning process; 2) By connecting the crushing part to the original carbon black dust collection pipeline through the butterfly valve, it is convenient to close the butterfly valve to cleave the crushed part online when the crushing part is repaired, maintained or replaced, without affecting the normal operation of the carbon black production line; 3) The mechanism described in this utility model has a simple structure, low cost and good effect.

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 , 2 As shown in Figure 3, a mechanism for online cleaning and recycling of carbon black adhering to the walls of a carbon black suction pipeline includes a collection device 1 for collecting carbon black, a suction fan 2, and a carbon black suction pipeline 3. The carbon black suction pipeline 3 is vertically arranged, with its top port connected to the inlet of the suction fan 2 and its outlet connected to the collection device 1. The carbon black suction pipeline 3 is also provided with at least one carbon black dust inlet 4. A cylindrical crushing chamber 5 is coaxially sealed and fixed to the bottom port of the carbon black suction pipeline 3. The bottom port of the crushing chamber 5 is connected to a flange 10 (known to those skilled in the art). The flange at this location, i.e., the motor flange on the crushing motor, and the bottom port of the crushing chamber are provided with a connecting flange. The motor flange and the connecting flange are adapted to form a flange structure. A crushing motor 6 is coaxially arranged. The rotating shaft of the crushing motor 6 extends into the crushing chamber 5. Multiple crushing blades 7 are circumferentially distributed on the rotating shaft of the crushing motor 6. Multiple compressed air ports are provided on the bottom circumferential wall of the crushing chamber 5. The height of the multiple compressed air ports is lower than the height of the crushing blades 7. Each compressed air port is provided with a compressed air pipe 8 arranged along the tangential direction of the crushing chamber 5.

[0023] In use, carbon black dust generated during carbon black production is fed into the carbon black dust suction line 3 through the carbon black dust inlet 4. Compressed air is introduced into each compressed air pipe 8. When it is necessary to treat the carbon black adhering to the wall in the carbon black dust suction line 3, the crushing motor 6 is started, and the carbon black dust suction line 3 is manually tapped. The carbon black adhering to the wall in the carbon black dust suction line 3 falls into the crushing chamber 5. The shaft of the crushing motor 6 rotates, driving the crushing blades 7 on it to rotate. The crushing blades 7 crush the fallen carbon black adhering to the wall. At the same time, multiple compressed air pipes 8 blow the smaller, incompletely crushed carbon black lumps that have been thrown to the periphery of the crushing chamber 5 toward the crushing head 7 area for further crushing, thereby improving the crushing efficiency of the carbon black hanging on the wall. After being crushed, the lumps of carbon black become carbon black dust, which is blown up by the compressed air and then sucked into the collection device 1 by the dust collector 2 through the carbon black dust collection pipeline 3. This realizes the online cleaning and recycling of the carbon black hanging on the wall in the carbon black dust collection pipeline 3, reducing the labor intensity of the operators and avoiding secondary pollution to the environment during the carbon black cleaning process.

[0024] In practice, the bottom port of the carbon black dust collection pipeline 3 is connected to the top port of the crushing chamber 5 via a butterfly valve 9. When the crushing chamber 5, crushing motor 6, or crushing blade 7 needs maintenance or replacement, the carbon black can be discharged online by closing the butterfly valve 9, without affecting the normal operation of the carbon black production line.

[0025] In practice, the pulverizing chamber 5 includes an upper chamber 51, a transition chamber 52, and a lower chamber 53, all coaxially arranged with the carbon black dust collection pipeline 3. Both the upper chamber 51 and the lower chamber 53 are cylindrical. The diameter of the upper chamber 51 is equal to the diameter of the carbon black dust collection pipeline 3. The transition chamber 52 is a frustum-shaped cylinder. The pulverizing head 7 is located inside the lower chamber 53. The distance between the edge of the pulverizing head 7 and the shaft center of the pulverizing motor 6 is equal to the radius of the upper chamber 51. The pulverizing chamber 5 is designed with a narrower top and a wider bottom to ensure that the carbon black adhering to the walls of the carbon black dust collection pipeline 3 falls onto the pulverizing head 7 as much as possible, thus improving pulverizing efficiency.

[0026] In this specific embodiment, there are four shredder heads 7 arranged in a cross shape, three compressed air ports, and three compressed air pipes 8, making the structure more specific and standardized.

[0027] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
