Description

Technical Field

[0001] This utility model relates to the field of raw material oil atomization technology, specifically a raw material oil atomization device for carbon black production. Background Technology

[0002] The carbon black market is currently experiencing intensified competition. With the development of the rubber industry and the influence of environmental protection and international and domestic situations, improving product quality is the most effective way to enhance market competitiveness. The coloring strength and compression oil absorption value of carbon black are key indicators for judging the quality of carbon black, and they also directly affect the dispersibility of carbon black in rubber, the tensile strength of the compound, and the wear resistance of tires, among other indicators. The atomization effect and reaction temperature of the raw material oil are important factors affecting the coloring strength and nitrogen adsorption of carbon black. At the same time, in the field of carbon black production technology, the atomization effect of the raw material oil is directly related to the quality and production efficiency of carbon black products. The raw material oil atomization device disperses the liquid raw material oil into tiny oil droplets, allowing them to fully contact with the high-temperature, high-speed airflow and undergo a cracking reaction, ultimately generating carbon black particles.

[0003] Traditional atomizing components are typically installed using threaded fastening or welding, with oil gun positioning relying on manual calibration. Precise control of the oil gun distribution spacing across the radial section of the throat is difficult, and maintenance requires repeated disassembly and reassembly of connecting components. This design is prone to positioning deviations due to thermal expansion and contraction during long-term operation, causing turbulent atomization flow. Furthermore, the complex disassembly and reassembly process significantly extends equipment maintenance time, forcing frequent production line interruptions and failing to meet the demands of modern carbon black production for continuous operation and rapid process adjustments. Existing atomizing devices usually employ a single-layer oil gun layout, with the atomization coverage limited by the oil gun density across the radial section of the throat, leading to insufficient atomization in localized areas and directly affecting the uniformity and yield of carbon black particles. Therefore, a raw material oil atomizing device for carbon black production is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a raw material oil atomization device for carbon black production, which solves the technical problem that the atomization coverage is limited by the oil gun configuration density of the radial cross section of the throat tube, resulting in insufficient atomization in local areas, which directly affects the uniformity and yield of carbon black particles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material oil atomization device for carbon black production, comprising:

[0006] The throat section, and the raw material oil gun inlet and the small water bubble oil gun inlet are provided around the surface of the throat section, and the connecting ring plate is provided around the surface of the throat section, and the position of the connecting ring plate corresponds to the raw material oil gun inlet and the small water bubble oil gun inlet.

[0007] A positioning side groove is formed on the upper part of the inner wall of the connecting ring plate, and a limiting ring groove is formed at the center of the inner wall of the connecting ring plate. The positioning side groove and the limiting ring groove are interconnected, and a fixed plug is inserted and connected to the upper part of the inner cavity of the positioning side groove.

[0008] The ring connecting plate is rotatably connected to the center of the inner cavity of the connecting ring plate, and positioning side posts are installed on both sides of the ring connecting plate. The positioning side posts correspond to the positioning side grooves, and the surface of the positioning side grooves rotates and fits against the inner wall of the limiting ring groove.

[0009] The raw material oil enters the reactor through the raw material oil gun inlet and the small water bubble oil gun inlet, which are evenly distributed around the surface of the throat section. The raw material oil gun inlet and the small water bubble oil gun inlet are equidistantly arranged along the same radial section of the throat section, with a total of 12 oil guns, to achieve multi-point spray atomization.

[0010] After the raw oil is sprayed out by the oil gun, it forms a fine oil droplet mist field in the throat section. The newly added four small water bubble oil guns have an independently adjustable inner extension length design. The nozzle tip can penetrate into the middle area of ​​the throat section along the axial direction of the throat section, making up for the atomization gap in the center of the original eight oil guns and making the oil droplet distribution more uniform.

[0011] Each oil gun is connected to the throat section via a connecting ring plate. During installation, the outer wall of the oil gun is inserted into the connecting ring plate along the positioning side groove. The ring plate and positioning side post move along the positioning side groove with the oil gun. The positioning side post enters the limiting ring groove until the oil gun flange end face enters the raw material oil gun inlet and the small bubble oil gun inlet. Then, the fixing rod is inserted into the top opening of the positioning side groove to complete the axial and circumferential positioning of the oil gun and ensure the consistency of the spray angle.

[0012] The atomized raw material oil droplets come into full contact with the high-temperature, high-speed airflow in the throat section, generating primary carbon black particles through incomplete combustion, shear collision, and pyrolysis reactions, which then enter the reaction chamber to complete the carbon black generation process.

[0013] Preferably, the inner cavity of the connecting ring plate is hollow, and the inner cavity of the connecting ring plate is connected to the raw material oil gun inlet and the small water bubble oil gun inlet.

[0014] During assembly, the inner cavity of the connecting ring plate is designed as a hollow structure. Through machining, its inner cavity forms a direct communication channel with the raw material oil gun inlet and the small bubble oil gun inlet, respectively. When the fuel delivery system is started, the raw material oil and the small bubble fuel enter the hollow cavity of the connecting ring plate through their respective inlets, realizing the independent delivery and centralized management of the two media.

[0015] Preferably, an outer connecting plate is added to both sides of the connecting ring plate, and a side connecting rod is installed on both sides of the outer connecting plate, and the side connecting rod is connected to the connecting ring plate.

[0016] External connecting plates are installed on both sides of the connecting ring plate, and the two ends of the side connecting rod are rigidly connected to the external connecting plates and the connecting ring plate respectively by welding or bolting.

[0017] Preferably, the fixed plug is inserted into the outer connecting plate, and an outer connecting handle is installed at the outer end of the fixed plug, and the outer connecting handle rotates and fits against the surface of the outer connecting plate.

[0018] Insert the fixing rod into the preset positioning hole of the outer connecting plate, and its end face will form a surface contact with the surface of the outer connecting plate. When disassembly is required, pull and rotate the outer connecting handle to release the fixing rod from the locked state, so as to achieve a quick separation operation.

[0019] Preferably, each of the fixed insertion rods is equipped with a fixing ring plate, and the surface of the fixing ring plate is in contact with the surface of the connecting ring plate.

[0020] During the insertion of the fixed rod, the fixed ring plate mounted on its surface moves synchronously with the rod. When the design position is reached, the annular end face of the fixed ring plate fits tightly with the corresponding surface of the connecting ring plate.

[0021] Preferably, the fixed insert is fitted with a compression spring, and the two ends of the compression spring are respectively attached to the outer connecting plate and the fixed ring plate.

[0022] The compression spring is pre-installed at the designated position of the fixed insertion rod. After the fixed insertion rod completes the insertion action, the two ends of the compression spring form elastic contact with the outer connecting plate and the fixed ring plate respectively. Under the vibration condition of the equipment operation, the compression spring absorbs the impact energy through axial deformation and the buffer pads used in conjunction.

[0023] Compared with the prior art, this utility model provides a raw material oil atomization device for carbon black production, which has the following beneficial effects:

[0024] The raw material oil atomization device for carbon black production adds small water bubble oil guns to the same radial section of the throat pipe, increasing the total number of raw material oil guns, making the sprayed raw material oil droplets finer, enhancing the atomization effect of the raw material oil, significantly increasing the atomization coverage density, and optimizing the atomization effect of the raw material oil. The atomized oil droplets come into more complete contact with the high temperature and high speed airflow, thereby improving the shear atomization reaction of the raw material oil, thus improving the quality of carbon black products, increasing the probability of carbon black formation, and reducing the unit consumption of raw materials.

[0025] The raw material oil gun and the small bubble oil gun achieve rapid positioning through the mechanical cooperation of the ring connecting plate and the connecting ring plate. The positioning side column moves along the positioning side groove and is combined with the circumferential constraint of the limiting ring groove to ensure the installation accuracy of the oil gun. At the same time, a reliable mechanical locking is formed by the fixed plug rod. This structural design not only ensures the installation stability of the atomizing component, but also simplifies the equipment maintenance process, effectively shortens the downtime required for process adjustment, and provides equipment support for continuous production.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides a technical solution: a raw material oil atomization device for carbon black production, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The throat section 1, and the raw material oil gun inlet 2 and the small water bubble oil gun inlet 3 are provided around the surface of the throat section 1. A connecting ring plate 4 is provided around the surface of the throat section 1, and the positions of the connecting ring plate 4 and the raw material oil gun inlet 2 and the small water bubble oil gun inlet 3 correspond to each other.

[0035] The positioning side groove 5 is opened on the upper part of the inner wall of the connecting ring plate 4, and the center of the inner wall of the connecting ring plate 4 is opened with a limiting ring groove 6. The positioning side groove 5 and the limiting ring groove 6 are connected to each other, and a fixed plug rod 11 is inserted and connected to the upper part of the inner cavity of the positioning side groove 5.

[0036] The ring connecting plate 7 is rotatably connected to the center of the inner cavity of the connecting ring plate 4, and positioning side posts 8 are installed on both sides of the ring connecting plate 7. The positioning side posts 8 correspond to the positioning side grooves 5, and the surface of the positioning side grooves 5 is rotatably fitted with the inner wall of the limiting ring grooves 6.

[0037] The raw material oil enters the reactor through the raw material oil gun inlet 2 and the small water bubble oil gun inlet 3, which are evenly distributed around the surface of the throat section 1. The raw material oil gun inlet 2 and the small water bubble oil gun inlet 3 are arranged equidistantly along the same radial section of the throat section 1. A total of 12 oil guns are set up, including the original 8 raw material oil guns and the newly added 4 small water bubble oil guns, to achieve multi-point spray atomization.

[0038] After the raw oil is sprayed out by the oil gun, it forms a fine oil droplet mist field in the throat section 1. The newly added 4 small water bubble oil guns have an independently adjustable inner extension length design, and their nozzle ends can penetrate into the middle area of ​​the throat along the axial direction of the throat section 1, making up for the atomization gap in the center of the original 8 oil guns, so that the oil droplets are more evenly distributed.

[0039] Each oil gun is connected to the throat section 1 via a connecting ring plate 4. During installation, the outer wall of the oil gun is inserted into the connecting ring plate 4 along the positioning side groove 5. The ring connecting plate 7 and the positioning side column 8 move along the positioning side groove 5 with the oil gun. The positioning side column 8 enters the limiting ring groove 6 until the oil gun flange end face enters the raw material oil gun inlet 2 and the small water bubble oil gun inlet 3. Then, the fixing rod 11 is inserted into the top opening of the positioning side groove 5 to complete the axial and circumferential positioning of the oil gun and ensure the consistency of the spray angle.

[0040] The atomized raw material oil droplets come into full contact with the high-temperature and high-speed airflow in the throat section 1, and generate primary carbon black particles through incomplete combustion, shear collision and pyrolysis reaction, and then enter the reaction chamber to complete the carbon black generation process;

[0041] By adding 4 small water bubble oil gun inlets 3 to the same radial section of the throat section 1, the total number of oil guns reaches 12, which increases the number density of sprayed oil droplets, reduces the average particle size of oil droplets, and improves the atomization uniformity index.

[0042] The newly added small water bubble oil gun can independently adjust the inner extension length. Its nozzle end extends into the central area of ​​the throat, forming a cross-spray layout with the original 8 raw material oil guns, effectively covering the entire axial cross section of the throat section 1, eliminating a certain atomization blind spot in the central part of the traditional design.

[0043] The modularly designed connecting ring plate 4 supports quick assembly and disassembly of a single oil gun, and the fixed plug rod 11 adopts a wedge-shaped self-locking structure, which shortens the replacement time of a single oil gun and improves maintenance efficiency compared with the traditional flange connection method.

[0044] Please see Figure 1The inner cavity of the connecting ring plate 4 is hollow and is connected to both the raw material oil gun inlet 2 and the small bubble oil gun inlet 3. During assembly, the inner cavity of the connecting ring plate 4 is designed as a hollow structure, and through machining, it forms direct communication channels with both the raw material oil gun inlet 2 and the small bubble oil gun inlet 3. When the fuel delivery system is started, the raw material oil and the small bubble fuel enter the hollow cavity of the connecting ring plate 4 through their respective inlets, achieving independent delivery and centralized management of the two media. The hollow cavity design ensures that the raw material oil and the small bubble fuel maintain independent channels during delivery, avoiding the risk of media mixing. It also simplifies the pipeline connection structure and improves the integration and maintenance convenience of the fuel supply system.

[0045] Please see Figure 5 External connecting plates 9 are added to both sides of the connecting ring plate 4, and side connecting rods 10 are installed on both sides of the external connecting plates 9, and the side connecting rods 10 are connected to the connecting ring plate 4. The external connecting plates 9 are installed on both sides of the connecting ring plate 4, and the two ends of the side connecting rods 10 are rigidly connected to the external connecting plates 9 and the connecting ring plate 4 respectively by welding or bolting; the external connecting plates 9 are connected to the connecting ring plate 4 through the side connecting rods 10, thereby ensuring connection stability. Fixed insert rods 11 are inserted and connected to the external connecting plates 9, and external connecting handles 14 are installed on the outer ends of the fixed insert rods 11, with the external connecting handles 14 rotatably fitting against the surface of the external connecting plates 9. Insert the fixing rod 11 into the preset positioning hole of the outer connecting plate 9, and its end face forms a surface contact with the surface of the outer connecting plate 9. When disassembly is required, pull and rotate the outer connecting handle 14 to release the fixing rod 11 from the locked state and realize a quick separation operation. The cooperation design between the fixing rod 11 and the outer connecting handle 14 provides a reliable mechanical locking function to prevent the connecting parts from accidentally falling off during equipment operation.

[0046] Please see Figure 6 Each fixed insertion rod 11 has a fixed ring plate 13 mounted on its surface, and the surface of the fixed ring plate 13 is in contact with the surface of the connecting ring plate 4. During the insertion of the fixed insertion rod 11, the fixed ring plate 13 mounted on its surface moves synchronously with the insertion rod. When the designed position is reached, the annular end face of the fixed ring plate 13 forms a tight fit with the corresponding surface of the connecting ring plate 4. The fixed ring plate 13 achieves precise axial positioning through end face contact, effectively controls the insertion depth of the fixed insertion rod 11, avoids structural damage caused by over-insertion, and increases the contact area to disperse local stress.

[0047] The fixed insertion rod 11 is fitted with a compression spring 12, and the two ends of the compression spring 12 are respectively attached to the outer connecting plate 9 and the fixed ring plate 13.

[0048] The compression spring 12 is pre-installed in the designated position of the fixed insertion rod 11. After the fixed insertion rod 11 completes the insertion action, the two ends of the compression spring 12 form elastic contact with the outer connecting plate 9 and the fixed ring plate 13 respectively. Under the vibration condition of the equipment operation, the compression spring 12 absorbs the impact energy through axial deformation and the buffer pad used in conjunction.

[0049] The compression spring 12 provides continuous preload compensation, eliminating connection gaps while buffering mechanical vibrations, ensuring that the fixed plug 11 connection is always in the best tightness, reducing noise generation and improving system operation stability.

[0050] This solution: The throat section 1 is used as the core component. Raw material oil gun inlet 2 and small water bubble oil gun inlet 3 are symmetrically opened around its surface. The inlets are equidistantly arranged circumferentially along the same radial section to form 12 installation points. A connecting ring plate 4 is welded to the outside of each inlet to ensure that the inner cavity of the connecting ring plate 4 is connected to the corresponding inlet. An outer connecting plate 9 is installed on both sides of the connecting ring plate 4 by welding or bolting. The outer connecting plate 9 forms a rigid connection structure with the connecting ring plate 4 through the side connecting rod 10.

[0051] The raw material oil gun and the small water bubble oil gun are inserted into the inner cavity of the connecting ring plate 4 along the positioning side groove 5. The outer wall of the oil gun and the positioning side groove 5 form a sliding fit. During the insertion of the oil gun, the ring connecting plate 7 connected to its end drives the positioning side column 8 to move along the positioning side groove 5. When the positioning side column 8 enters the limiting ring groove 6, the oil gun is rotated to make the positioning side column 8 rotate along the inner wall of the limiting ring groove 6 to a preset angle, thus completing the circumferential positioning of the oil gun.

[0052] The fixed insertion rod 11 is passed through the preset hole of the outer connecting plate 9 and the top opening of the positioning side groove 5 of the connecting ring plate 4 in sequence. The two ends of the compression spring 12 sleeved on the surface of the fixed insertion rod 11 form elastic contact with the outer connecting plate 9 and the fixed ring plate 13 respectively. When the fixed insertion rod 11 is inserted to the designed depth, the end face of the fixed ring plate 13 fits against the surface of the connecting ring plate 4, and the outer connecting handle 14 forms a rotation limit with the outer surface of the outer connecting plate 9. The oil gun is axially locked through the wedge-shaped self-locking structure.
