Description

Technical Field

[0001] This utility model belongs to the field of carbon calcination technology and relates to carbon calcination equipment. Background Technology

[0002] Carbon calcination is an important step in the carbon production process. It mainly refers to the process of heat-treating various carbon raw materials (such as petroleum coke, pitch coke, anthracite, etc.) at high temperatures. The purpose of calcination is to remove volatiles from the raw materials. At the same time, the microstructure of the raw materials changes under high-temperature calcination, which can reduce the gaps between particles, increase the density and mechanical strength of the raw materials, and improve the internal crystal structure of the raw materials after calcination. Impurities are further removed, thereby enhancing their electrical conductivity.

[0003] The existing carbon calcination method involves directly calcining carbon raw materials in a rotary kiln. However, the carbon raw materials are not uniform in size, which increases the time required to fully calcine the raw materials and reduces calcination efficiency. Furthermore, during calcination in the rotary kiln, the uneven size of the raw materials not only causes uneven heating and affects the calcination quality, but also makes it difficult for workers to determine the calcination time. Utility Model Content

[0004] The purpose of this invention is to provide a carbon calcination treatment device that solves the problem in the prior art where uneven heating of raw materials of different sizes during carbon calcination affects the calcination quality.

[0005] The technical solution adopted by this utility model includes a grinding barrel with a feed inlet on one side. A crushing motor is fixedly connected to the top of the grinding barrel, and a crushing rod is fixedly connected to the output end of the crushing motor. The crushing rod extends into the grinding barrel, and a screening assembly is fixedly connected to the grinding barrel below the crushing rod. Each discharge port of the screening assembly is fixedly connected to a stirring assembly through a pipe. Each stirring assembly is connected to the same calcining rotary kiln through a pipe. A preheating assembly is fixedly connected to one side of the calcining rotary kiln, and the preheating assembly is connected to each stirring assembly through a pipe.

[0006] The features of this utility model also include:

[0007] The screening assembly includes a horizontal screen fixedly connected inside the grinding barrel and located below the crushing rod. Below the horizontal screen, a first inclined screen and a second inclined screen are arranged in sequence. The first and second inclined screens are fixedly connected to the inner wall of the grinding barrel. The inner wall of the grinding barrel, corresponding to the lowest points of the first and second inclined screens, is fixedly connected to a stirring assembly via pipes. The stirring assembly is connected to the bottom of the second inclined screen via a pipe. The apertures of the horizontal screen, the first inclined screen, and the second inclined screen gradually decrease.

[0008] Crushing blades are fixedly connected to the side of the crushing rod, and the bottom surface of the crushing blades abuts against the horizontal screen.

[0009] Each mixing component has the same structure, including a mixing tank that is fixedly connected to the grinding tank, a mixing motor that is fixedly connected to the bottom of the mixing tank, a mixing rod that is fixedly connected to the output end of the mixing motor that extends into the mixing tank, and a preheating pipe that is connected to the preheating component.

[0010] The rotary kiln for calcination is fixedly connected with partitions, which divide the interior of the rotary kiln into multiple calcination chambers. The number of calcination chambers is the same as the number of stirring components.

[0011] The preheating assembly includes a flue gas filter connected to the calcining rotary kiln via a pipeline. The flue gas filter is connected to a booster pump via a pipeline. The input end of the booster pump is connected to the calcining rotary kiln via a pipeline, and the output end is connected to the preheating pipeline via a pipeline.

[0012] The booster pump connects to the stirring components in descending order of the diameter of the stored carbon. The last stirring component connected to the booster pump has a pressure relief component fixedly connected to the output end of the preheating pipe.

[0013] The pressure relief assembly includes a pressure relief cover fixedly connected to the preheating pipe. Several pressure relief holes are opened on the side wall of the pressure relief cover away from the preheating pipe. A pressure relief plate is provided inside the pressure relief cover near the preheating pipe. An adjusting plate is provided above the pressure relief plate. A spring is fixedly connected between the pressure relief plate and the adjusting plate. An adjusting bolt passes through the top of the pressure relief cover. The adjusting bolt extends into the pressure relief cover along the spring axis and abuts against the adjusting plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a crushing motor to drive the crushing rod to rotate, crushing large pieces of carbon into carbon particles, improving the uniformity of carbon raw material size, thereby ensuring the uniformity of heating of carbon raw material during calcination and improving calcination quality.

[0016] 2. This utility model uses a booster pump to transport the hot air generated in the calcining rotary kiln to the preheating pipe, preheating the carbon before it enters the calcining rotary kiln. This not only reduces the time required for the raw materials to enter the calcining rotary kiln for calcination, but also allows for the reuse of the heat from the calcining rotary kiln, improving calcination efficiency while reducing energy loss.

[0017] 3. This utility model classifies crushed carbon according to the diameter of carbon particles through a screening component and transports them to different mixing tanks for preheating. This effectively avoids the problem of uneven heating of carbon particles of different sizes, which leads to low preheating effect. At the same time, the hot air generated in the calcination rotary kiln preferentially heats the carbon particles with larger diameters and then heats the carbon particles with smaller diameters. This shortens the preheating time and improves the carbon processing efficiency while ensuring the preheating effect. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] like Figure 1As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0027] During the calcination of carbon, the crushing motor 3 first drives the crushing rod 4 to rotate, crushing the lumpy carbon fed into the grinding barrel 1 from the feed port 2 into powder. Then, the screening component 5 separates the carbon into different types according to the diameter of the crushed carbon particles and sends them into the corresponding stirring component 6. At the same time, the preheating component 8 sends the hot air from the calcination rotary kiln 7 into the stirring component 6, preheating the crushed carbon before calcination, improving the physical properties of the carbon, shortening the calcination time, and facilitating the stable operation of the calcination process.

[0028] Example 2:

[0029] like Figure 1 As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0030] like Figure 2 As shown, the screening component 5 includes a horizontal screen 9 fixedly connected inside the grinding barrel 1 and located below the crushing rod 4. Below the horizontal screen 9, a first inclined screen 10 and a second inclined screen 11 are arranged in sequence. The first inclined screen 10 and the second inclined screen 11 are fixedly connected to the inner wall of the grinding barrel 1. The inner wall of the grinding barrel 1 is connected to the lowest point of the first inclined screen 10 and the second inclined screen 11 respectively through pipes, and the stirring component 6 is connected to the lower part of the second inclined screen 11 through a pipe. The aperture of the horizontal screen 9, the first inclined screen 10 and the second inclined screen 11 gradually decreases.

[0031] Crushing blades 26 are fixedly connected to the side of the crushing rod 4, and the bottom surface of the crushing blades 26 abuts against the horizontal screen 9.

[0032] The crushing blades 26 abut against the horizontal screen 9. During the rotation of the crushing rod, the crushed carbon can be pushed by the crushed blades to move on the upper surface of the horizontal screen 9, thereby increasing the screening speed of the carbon and improving the screening efficiency.

[0033] When the first inclined screen 10 and the second inclined screen 11 are inclined, the crushed carbon moves on the two inclined screens by its own gravity. Carbon with a diameter larger than the inclined screen moves along the inclined direction under its own gravity and enters the corresponding stirring component 6 through the pipe. The transfer of carbon can be completed without the need for a power component.

[0034] Example 3:

[0035] like Figure 1 As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0036] like Figure 2 As shown, the screening component 5 includes a horizontal screen 9 fixedly connected inside the grinding barrel 1 and located below the crushing rod 4. Below the horizontal screen 9, a first inclined screen 10 and a second inclined screen 11 are arranged in sequence. The first inclined screen 10 and the second inclined screen 11 are fixedly connected to the inner wall of the grinding barrel 1. The inner wall of the grinding barrel 1 is connected to the lowest point of the first inclined screen 10 and the second inclined screen 11 respectively through pipes, and the stirring component 6 is connected to the lower part of the second inclined screen 11 through a pipe. The aperture of the horizontal screen 9, the first inclined screen 10 and the second inclined screen 11 gradually decreases.

[0037] Crushing blades 26 are fixedly connected to the side of the crushing rod 4, and the bottom surface of the crushing blades 26 abuts against the horizontal screen 9.

[0038] like Figure 3 As shown, each stirring component 6 has the same structure, including a stirring tank 12 fixedly connected to the grinding tank 1, a stirring motor 13 fixedly connected to the bottom of the stirring tank 12, a stirring rod 14 fixedly connected to the output end of the stirring motor 13 extending into the stirring tank 12, and a preheating pipe 15 surrounding the inner wall of the stirring tank 12, which is connected to the preheating component 8.

[0039] The preheating component 8 is connected to the preheating pipe 15, which sends hot air from the calcination rotary kiln 7 into the preheating pipe 15 to preheat the carbon in the mixing tank 12. During the heating process, the stirring motor 13 drives the stirring rod 14 to rotate, which fully stirs the carbon and avoids uneven heating of the inner and outer layers of carbon, which would reduce the heating effect.

[0040] Example 4:

[0041] like Figure 1 As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0042] like Figure 4 As shown, a partition 16 is fixedly connected inside the calcining rotary kiln 7. The partition 16 divides the inside of the calcining rotary kiln 7 into multiple calcining chambers 17. The number of calcining chambers 17 is the same as the number of stirring components 6.

[0043] The calcination conditions required for carbon particles of different diameters are usually inconsistent. For example, small-diameter carbon particles have a relatively large specific surface area, resulting in faster heat transfer and diffusion. They can reach the required reaction temperature more quickly during calcination, thus requiring a shorter calcination time. However, large-diameter carbon particles may not be heated evenly in the rotary kiln 7, with a temperature gradient between their interior and exterior. To ensure complete calcination and achieve the desired physicochemical properties, a longer calcination time is often necessary. Therefore, the rotary kiln 7 is divided into multiple calcination chambers 17 by partitions to accommodate the heating needs of carbon particles of different sizes.

[0044] Example 5:

[0045] like Figure 1 As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0046] like Figure 2 As shown, the screening component 5 includes a horizontal screen 9 fixedly connected inside the grinding barrel 1 and located below the crushing rod 4. Below the horizontal screen 9, a first inclined screen 10 and a second inclined screen 11 are arranged in sequence. The first inclined screen 10 and the second inclined screen 11 are fixedly connected to the inner wall of the grinding barrel 1. The inner wall of the grinding barrel 1 is connected to the lowest point of the first inclined screen 10 and the second inclined screen 11 respectively through pipes, and the stirring component 6 is connected to the lower part of the second inclined screen 11 through a pipe. The aperture of the horizontal screen 9, the first inclined screen 10 and the second inclined screen 11 gradually decreases.

[0047] Crushing blades 26 are fixedly connected to the side of the crushing rod 4, and the bottom surface of the crushing blades 26 abuts against the horizontal screen 9.

[0048] like Figure 3 As shown, each stirring component 6 has the same structure, including a stirring tank 12 fixedly connected to the grinding tank 1, a stirring motor 13 fixedly connected to the bottom of the stirring tank 12, a stirring rod 14 fixedly connected to the output end of the stirring motor 13 extending into the stirring tank 12, and a preheating pipe 15 surrounding the inner wall of the stirring tank 12, which is connected to the preheating component 8.

[0049] like Figure 1 and Figure 4 As shown, the preheating component 8 includes a flue gas filter 27 connected to the calcining rotary kiln 7 via a pipeline. The flue gas filter 27 is connected to a booster pump 18 via a pipeline. The input end of the booster pump 18 is connected to the calcining rotary kiln 7 via a pipeline, and the output end is connected to the preheating pipeline 15 via a pipeline.

[0050] The booster pump 18 is connected to the stirring assembly 6 in descending order of the diameter of the stored carbon. The last stirring assembly 6 connected to the booster pump 18 is fixedly connected to the pressure relief assembly 19 at the output end of the preheating pipe 15.

[0051] The booster pump 18 is used to transport hot gas from the calcining rotary kiln 7 to the stirring assembly to preheat the carbon. The stirring assembly 6 is connected according to the diameter of the stored carbon, from largest to smallest, to preferentially heat the larger diameter carbon and then the smaller diameter carbon. Large-diameter carbon is heated unevenly, and the pile of carbon has large voids and low heat transfer efficiency; therefore, more heat is used to preheat the large-diameter carbon. Conversely, small-diameter carbon has a relatively faster heat transfer and diffusion rate, so less heat is used for heating.

[0052] During calcination in the rotary kiln 7, a large amount of flue gas is generated. When the booster pump 18 transfers hot gas, some of this flue gas enters the booster pump 18 and the preheating pipe 15. This flue gas emission may impact the environment, and the accumulation of flue gas in the pipes may also clog them, affecting the preheating effect. Therefore, a flue gas filter 27 is installed between the rotary kiln 7 and the booster pump 18 to prevent flue gas from entering the booster pump 18 and the preheating pipe 15.

[0053] Example 6:

[0054] like Figure 1 As shown, the device includes a grinding barrel 1 with a feed inlet 2 on one side. A crushing motor 3 is fixedly connected to the top of the grinding barrel 1, and a crushing rod 4 is fixedly connected to the output end of the crushing motor 3. The crushing rod 4 extends into the grinding barrel 1, and a screening assembly 5 is fixedly connected to the grinding barrel 1 below the crushing rod 4. Each discharge port of the screening assembly 5 is fixedly connected to a stirring assembly 6 through a pipe. Each stirring assembly 6 is connected to the same calcining rotary kiln 7 through a pipe. A preheating assembly 8 is fixedly connected to one side of the calcining rotary kiln 7, and the preheating assembly 8 is connected to each stirring assembly 6 through a pipe.

[0055] like Figure 2 As shown, the screening component 5 includes a horizontal screen 9 fixedly connected inside the grinding barrel 1 and located below the crushing rod 4. Below the horizontal screen 9, a first inclined screen 10 and a second inclined screen 11 are arranged in sequence. The first inclined screen 10 and the second inclined screen 11 are fixedly connected to the inner wall of the grinding barrel 1. The inner wall of the grinding barrel 1 is connected to the lowest point of the first inclined screen 10 and the second inclined screen 11 respectively through pipes, and the stirring component 6 is connected to the lower part of the second inclined screen 11 through a pipe. The aperture of the horizontal screen 9, the first inclined screen 10 and the second inclined screen 11 gradually decreases.

[0056] Crushing blades 26 are fixedly connected to the side of the crushing rod 4, and the bottom surface of the crushing blades 26 abuts against the horizontal screen 9.

[0057] like Figure 3 As shown, each stirring component 6 has the same structure, including a stirring tank 12 fixedly connected to the grinding tank 1, a stirring motor 13 fixedly connected to the bottom of the stirring tank 12, a stirring rod 14 fixedly connected to the output end of the stirring motor 13 extending into the stirring tank 12, and a preheating pipe 15 surrounding the inner wall of the stirring tank 12, which is connected to the preheating component 8.

[0058] like Figure 1 and Figure 4As shown, the preheating component 8 includes a flue gas filter 27 connected to the calcining rotary kiln 7 via a pipeline. The flue gas filter 27 is connected to a booster pump 18 via a pipeline. The input end of the booster pump 18 is connected to the calcining rotary kiln 7 via a pipeline, and the output end is connected to the preheating pipeline 15 via a pipeline.

[0059] The booster pump 18 is connected to the stirring assembly 6 in descending order of the diameter of the stored carbon. The last stirring assembly 6 connected to the booster pump 18 is fixedly connected to the pressure relief assembly 19 at the output end of the preheating pipe 15.

[0060] like Figure 5 As shown, the pressure relief assembly 19 includes a pressure relief cover 20 fixedly connected to the preheating pipe 15. The side wall of the pressure relief cover 20 away from the preheating pipe 15 has several pressure relief holes 21. A pressure relief plate 22 is provided inside the pressure relief cover 20 near the preheating pipe 15. An adjusting plate 23 is provided above the pressure relief plate 22. A spring 24 is fixedly connected between the pressure relief plate 22 and the adjusting plate 23. An adjusting bolt 25 passes through the top of the pressure relief cover 20. The adjusting bolt 25 extends into the pressure relief cover 20 along the axial direction of the spring 24 and abuts against the adjusting plate 23.

[0061] When too much heat accumulates in the preheating pipe 15, the pressure inside the pipe increases. Under the pressure, the pressure relief plate 22 gradually moves toward the adjusting bolt 25 and compresses the spring 24. When the pressure relief plate 22 exceeds the pressure relief hole 21, the gas in the preheating pipe 15 is discharged to the outside through the pressure relief hole 21. After the gas is discharged, the pressure inside the preheating pipe 15 decreases, and the spring 24 pushes the pressure relief plate 22 to reset so that the next round of preheating can be carried out.

[0062] The compression of the spring can be adjusted by rotating the adjusting bolt 25. When the adjusting bolt 25 is screwed into the pressure relief cover 20, the adjusting plate further compresses the spring 24. At this time, greater pressure is required to push the pressure relief plate 22 to release pressure, thus prolonging the pressure relief cycle. When the adjusting bolt 25 is screwed out of the pressure relief cover 20, the spring 24 extends. At this time, less pressure is required to push the pressure relief plate 22 to release pressure, thus shortening the pressure relief cycle. By changing the pressure relief cycle, the preheating time can be changed, thereby adjusting the preheating temperature.

[0063] Working principle:

[0064] During carbon calcination, the carbon to be processed is first fed into the grinding barrel 1 through the feed inlet 2. Then, the crushing motor 3 drives the crushing rod 4 to rotate and crush the large pieces of carbon into smaller carbon particles. The crushed carbon moves downward under the action of gravity and passes through the horizontal screen 9. After passing through the first inclined screen 10 and the second inclined screen 11, the carbon particles are divided into three categories according to their diameter from large to small and sent into different stirring components 6.

[0065] While the carbon is being crushed, the calcining rotary kiln 7 is started for heating. The booster pump 18 delivers hot air from the calcining rotary kiln 7 through a pipeline to the preheating pipe 15 on the inner wall of the mixing tank 12, thereby increasing the temperature inside the mixing tank 12. After the carbon enters the heated mixing tank 12, the stirring motor 13 drives the stirring rod 14 to rotate, ensuring that the carbon is fully heated.

[0066] After preheating, the carbon in different mixing tanks 12 is sent through pipelines into the calcining rotary kiln 7 for calcination.

[0067] Before calcination begins, the residence time of hot gas in the preheating pipe 15 can be adjusted by rotating the adjusting bolt 25 to adjust the compression of the spring 24, thereby controlling the preheating temperature.
