Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of carbon black processing equipment, and more specifically, to an automatic alignment device for a raw material oil lance. Background Art

[0002] Carbon black is an amorphous carbon, which is a black powdery substance formed by incomplete combustion or thermal cracking of hydrocarbon compounds (such as petroleum, natural gas, etc.) under high temperature and oxygen-deficient conditions. There are usually two methods for the reaction to produce carbon black, one is the incomplete combustion method, and the other is the cracking method. When using natural gas as the raw material in the incomplete combustion method, the natural gas is mixed with an appropriate amount of air and then ignited in a special reaction furnace to cause incomplete combustion of the natural gas. Under high temperature and oxygen-deficient conditions, the hydrocarbon compounds in the natural gas are cracked, and the carbon atoms are rearranged and combined to form carbon black particles. The reaction temperature is usually around 1200°C - 1500°C. The reaction is usually that the oil lance sprays into the reaction furnace for incomplete combustion. The reaction furnace has an insertion port, and the spray gun inserts into the paper reaction furnace from the insertion port to spray oil for incomplete combustion. Among them, the spray gun is not fixed on the reaction furnace but is located on one side of the reaction furnace. In the prior art, when inserting the spray gun into the reaction furnace, on the one hand, the manual operation has low safety. On the other hand, even though there are some guiding brackets in the prior art to guide the spray gun to insert into the insertion port of the reaction furnace, at different temperatures of the reaction furnace, due to thermal expansion and contraction, the height of the insertion port will change differently. Especially before the reaction furnace reacts, at room temperature, compared with the temperature of 1200°C - 1500°C during the reaction of the reaction furnace, the height of the insertion port will change to some extent, and the maximum height difference may reach several centimeters. This results in that the guiding bracket cannot well guide the spray gun into the insertion port of the reaction furnace, and it is difficult to insert the spray gun into the insertion port of the reaction furnace. Not only is the labor intensity of the operating workers large, but the manual operation has a high risk factor, and the dimensional accuracy of the lance entering and exiting is also poor, which affects the product quality. And in case of emergency, the lance cannot be quickly withdrawn. Summary of the Invention

[0021] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0022] As an important industrial raw material, carbon black is often produced by the incomplete combustion or thermal cracking of hydrocarbon compounds under high temperature and oxygen-deficient conditions. In the incomplete combustion method using natural gas as the raw material, an oil gun needs to spray oil from the insertion port of the reaction furnace for the reaction. In the prior art, the oil gun is not fixed to the reaction furnace. Manually inserting the oil gun not only has low safety, but also due to the thermal expansion and contraction of the reaction furnace at different temperatures, the height of the insertion port can change by several centimeters, resulting in difficulty for the traditional guiding bracket to accurately guide the insertion of the oil gun, which brings inconvenience to production. This automatic alignment device for the large oil gun of the raw material oil is used to solve these problems and realizes the automatic and accurate insertion of the oil gun through a specific structural design, improving the production safety and efficiency.

[0023] As Figures 1 - 2 shown, it shows an automatic alignment device for the large oil gun of the raw material oil in an embodiment of the present disclosure. The support frame 1 serves as the basic support structure of the entire device. While bearing the overall weight of the device, it needs to resist the influence of the high-temperature environment around the reaction furnace to ensure the structural stability. Its structure is designed as a frame type and is firmly connected to the ground through anchor bolts at the bottom to ensure no shaking during the operation of the device. The anchor bolts can be adjusted in height to adapt to the ground with different flatness and ensure that the support frame 1 is in a horizontal state. For example, in some industrial factory buildings, the ground may have slight unevenness. By adjusting the anchor bolts, the support frame 1 can be kept horizontal, providing a guarantee for the stable operation of the subsequent components. The height and width of the support frame 1 are determined according to the actual size of the reaction furnace and the requirements of the operation space of the oil gun, and sufficient moving space needs to be provided for the horizontal moving frame 2. Among them, the support frame 1 can also be designed to be able to be adjusted in both lifting and left-right directions. Commonly used adjustment structures in mechanical equipment can be adopted, and the position of the support frame 1 is adjusted by adjusting multi-dimensional sliders to adapt to reaction furnaces with different sizes and heights, improving the operation accuracy and precision of the equipment and making the equipment operation more flexible. To realize the normal entry and exit of the large oil gun and the furnace body in the large oil gun device, the position adjustment structure of the support frame 1 can have up-down and left-right manual adjustment devices to facilitate manual adjustment.

[0024] Improvement of Position Adjustment Flexibility and Precision: By improving the slider installation method, the support frame 1 of the large gun device can adjust its horizontal and vertical positions more flexibly. This design improves the adaptability of the equipment, enabling it to better meet the requirements of the operation scenario, and also significantly enhances the operation precision. In fields such as precision manufacturing and chemical production, this flexibility and precision are the keys to improving production efficiency and product quality.

[0025] The horizontal moving frame 2 moves on the support frame 1 to achieve position adjustment. It is mainly composed of a moving track and a moving platform, and the driving method is to drive by hand to adjust the position.

[0026] The first support ring 3 and the second support ring 4 move with the horizontal moving frame 2 and are spaced apart from each other. The inner diameters of the two support rings are slightly larger than the outer diameter of the raw material oil large gun 5, ensuring that the raw material oil large gun 5 can pass through smoothly and be well supported. They are connected to the moving platform of the horizontal moving frame 2 through connecting rods, keeping a suitable spacing distance between the two support rings to effectively support the raw material oil large gun 5 and prevent it from shaking during movement.

[0027] The raw material oil large gun 5 is installed on the first support ring 3 and the second support ring 4, and has a smooth flow channel inside to ensure that the raw material oil can pass through smoothly and be evenly sprayed. The head of the raw material oil large gun 5 is designed as a nozzle structure, and the nozzle has multiple small spray holes. The distribution and angle of these spray holes are optimized so that the raw material oil can quickly mix with air after being sprayed into the reaction furnace, achieving a good incomplete combustion effect.

[0028] A fuel pipeline is connected to the tail of the raw material oil large gun 5. The fuel pipeline is connected to the raw material oil storage tank, and the raw material oil is transported to the raw material oil large gun 5 through an oil pump. In order to accurately control the injection volume of the raw material oil, a flow regulating valve and a flow meter are installed on the fuel pipeline. Operators can adjust the flow regulating valve through the control system according to the reaction requirements to accurately control the injection volume of the raw material oil.

[0029] The automatic alignment device for the raw material oil lance is designed based on the principles of precise position control and adaptive adjustment. The support frame 1 provides a stable support foundation. The horizontal moving frame 2 achieves precise horizontal position control by means of a moving track and a driving component, and can accurately approach or move away from the position of the reaction furnace according to its position. The first support ring 3 and the second support ring 4 are installed on the horizontal moving frame 2, which not only provides stable support for the raw material oil lance 5, but also can adapt to the position change of the insertion port of the reaction furnace caused by thermal expansion and contraction through an angle adjustment mechanism. The raw material oil lance 5 realizes good spraying of the raw material oil in the reaction furnace through a nozzle and oil delivery control. Each part works together to achieve the automatic alignment of the raw material oil lance 5 and its insertion into the insertion port of the reaction furnace, improving the safety and accuracy of the production process. Usually, an iris valve is installed at the insertion port of the reaction furnace, and the valve blade of the iris valve is controlled to open and close the insertion port of the reaction furnace, and ensure that the insertion position of the raw material oil lance 5 remains centered.

[0030] The horizontal drive of the horizontal moving frame 2 can be electrically driven, and the power supply of the corresponding electric drive device is connected to the uninterruptible UPS power supply of the production line, so that the raw material oil lance 5 can be quickly withdrawn in case of an emergency power outage.

[0031] With the application of the alignment device, the operation convenience of the operator is greatly reduced, the exposure time of personnel in high-temperature and dangerous environments is reduced, and the risk of safety accidents such as scalding and explosion caused by factors such as high temperature and high pressure is reduced. For example, in the past, when manually inserting the spray gun, the operator needed to approach the high-temperature reaction furnace closely. Now, with this device, the operator can operate at a relatively safe distance, greatly improving the operation safety.

[0032] The device reduces the safety hazards caused by improper insertion of the spray gun. Accurate alignment and insertion reduce the collision and friction between the spray gun and the insertion port of the reaction furnace, avoiding safety accidents such as leakage and explosion caused by equipment damage, and further enhancing the safety of the entire production process.

[0033] The driving component and the moving track of the horizontal moving frame 2 can control the horizontal position, enabling the raw material oil lance 5 to accurately align with the insertion port of the reaction furnace in the horizontal direction. The positioning ensures that the spray gun can accurately reach the insertion port position, greatly improving the alignment accuracy and reducing the insertion difficulty caused by horizontal position deviation.

[0034] The first support ring 3 and the second support ring 4 can be designed with an additional angle adjustment mechanism, thus effectively solving the problem of height change of the insertion port of the reaction furnace caused by thermal expansion and contraction. Even if the height of the insertion port changes by a few centimeters, by adjusting the angle of the support ring, the raw material oil lance 5 can still accurately align with the insertion port in the vertical direction, improving the insertion success rate and ensuring the continuity of production.

[0035] The automatic alignment and insertion process significantly shortens the time required for the spray gun insertion, reducing production stagnation caused by difficult insertion. Compared with the traditional manual insertion of the spray gun, which may take several minutes or even longer, this device can complete the alignment and insertion operations within dozens of seconds, significantly improving production efficiency and enabling more efficient carbon black production. The stability and accuracy of the device reduce damage to the reaction furnace and the spray gun itself caused by improper spray gun insertion, lowering equipment maintenance costs and downtime. For example, traditional manual insertion may cause wear to the spray gun or the insertion port of the reaction furnace due to improper operation, requiring frequent repair and replacement of components, while this device can effectively avoid such problems, further improving the overall production efficiency.

[0036] Operators no longer need to perform the heavy manual plugging and unplugging of the spray gun. With simple operations, they can complete the alignment and insertion of the raw material oil lance 5, greatly reducing the labor intensity. For example, in the past, manual plugging and unplugging of the spray gun required operators to exert a large amount of physical effort, but now the operation has become easy and convenient, improving the work comfort of the operators. The simplified operation of the device reduces the working time of operators in harsh environments and improves the working conditions. Operators do not need to be exposed to high-temperature and high-dust environments for a long time, which is beneficial to protecting the physical health of operators.

[0037] The designed automatic control can optimize manual operations, transforming the traditional manual pushing and withdrawing operations of the lance into computer-programmed control. This upgrade reduces the dependence on manual intervention, not only lowering labor costs but also effectively reducing operation delays due to the instant responsiveness and consistency of computer control, enhancing the safety and efficiency of operations.

[0038] With enhanced environmental adaptability and self-protection functions, in the face of power outages or other emergencies, the device can be designed to automatically detect the current operating environment and quickly take measures to withdraw from adverse environments, such as avoiding equipment damage caused by continuous operation under high-temperature conditions. This intelligent self-protection mechanism greatly improves the durability of the equipment and reduces losses caused by high-temperature damage, which is of great significance for maintaining the continuity of the production line and reducing maintenance costs.

[0039] The operation is simple and practical. Starting and stopping are easy to master. The time of the intermediate switch valve connected to the raw material oil lance 5 can be adjusted, and different production times can be adjusted according to different situations. It can also be designed for remote visualization. The in-place and out-of-place can be monitored remotely, and remote control can be used for starting, returning to zero, withdrawing, and emergency withdrawing to orderly monitor the production situation of the raw material oil lance 5.

[0040] In some examples, such as Figures 1 - 2As shown in the figure, in order to further improve the flexibility and stability of the raw material oil lance in aligning under different working conditions, the structure is refined. By setting hinge structures among the support frame, the first support ring, the second support ring and the elastic telescopic rod, it is aimed to enable the raw material oil lance to better adapt to the position changes of the reaction furnace insertion port caused by factors such as thermal expansion and contraction, so as to more accurately align and insert into the reaction furnace insertion port, ensuring the efficiency and stability of the carbon black production process.

[0041] The first support part 201 of the horizontal moving frame 2 supports the first support ring 3. The first ball head 202 is integrally formed at the top of the first support part 201. The surface of the ball head is precisely polished with low roughness to reduce the friction with the first ball groove 301 and ensure that the hinge can rotate flexibly. The size of the first ball head 202 is determined according to the load-bearing requirements of the first support ring 3 and the overall structure design to provide sufficient supporting force and rotational freedom.

[0042] The second ball groove 203 is also arranged on the horizontal moving frame 2, corresponding to the first support part 201, and is used for hinging with the second ball head 601 of the elastic telescopic rod 6. The depth and radian of the second ball groove 203 are precisely matched with the second ball head 601 to ensure that after the two are hinged, they can rotate flexibly and will not loosen or shake, ensuring the overall stability of the device.

[0043] The first ball groove 301 is designed at the bottom of the first support ring 3. The first ball groove 301 and the first ball head 202 of the first support part 201 form a hinge structure. The first ball groove 301 and the first ball head 202 are closely matched, enabling the first support ring 3 to rotate flexibly around the first ball head 202 within a certain angle range. This hinge structure enables the first support ring 3 to make fine adjustments in the horizontal and vertical directions according to the position changes of the reaction furnace insertion port, thereby driving the raw material oil lance 5 to more accurately align with the insertion port.

[0044] The second support ring 4 is provided with a third ball groove 401 for hinging with the third ball head 602 of the elastic telescopic rod 6. The size and angle of the third ball groove 401 are optimized according to the installation position and movement requirements of the elastic telescopic rod 6 to ensure that after cooperating with the third ball head 602, it can provide stable and flexible support for the second support ring 4, enabling it to follow the adjustment of the first support ring 3 and jointly drive the raw material oil lance 5 to align with the reaction furnace insertion port.

[0045] The elastic telescopic rod 6 is a supporting component connecting the support frame 1 and the second support ring 4, and it has a second ball head 601 and a third ball head 602 at both ends respectively. The elastic telescopic rod 6 includes two rod bodies that can face each other and a spring sleeved outside the two rod bodies, and it can be telescoped within a certain range to adapt to the change in the distance between the second support ring 4 and the horizontal moving frame 2 when the position of the reactor insertion port changes. For example, when the position of the reactor insertion port changes due to thermal expansion and contraction, by manually operating the raw material oil lance 5 to fine-tune the angle, the elastic telescopic rod 6 can adjust the position of the second support ring 4 by telescoping, ensuring that the raw material oil lance 5 always aligns with the insertion port.

[0046] The second ball head 601 and the third ball head 602 are in close fit with the corresponding second ball groove 203 and third ball groove 401 to achieve flexible hinging. The telescopic range of the elastic telescopic rod 6 is designed according to the possible position change range of the reactor insertion port, generally about 5 - 10 centimeters, to meet the various working conditions requirements in actual production.

[0047] The design of this device is based on the principles of flexible adaptability and stable support. The first ball head 202 of the horizontal moving frame 2 is hinged with the first ball groove 301 of the first support ring 3, giving the first support ring 3 a rotational freedom within a certain range, enabling it to make fine adjustments according to the position change of the reactor insertion port, and then driving the raw material oil lance 5 to make corresponding adjustments in the horizontal and vertical directions. The elastic telescopic rod 6 is hinged with the second ball groove 203 of the support frame 1 and the third ball groove 401 of the second support ring 4 through the ball heads at both ends respectively. It not only provides stable support for the second support ring 4, but also can adapt to the change in the distance between the second support ring 4 and the horizontal moving frame 2 when the position of the reactor insertion port changes through its own telescoping, and cooperate with the first support ring 3 to make the raw material oil lance 5 more accurately align with the reactor insertion port. This design enables the entire device to automatically and flexibly adjust the position of the raw material oil lance 5 under complex working conditions to ensure its accurate insertion into the reactor insertion port.

[0048] The hinge structure between the first support ring 3 and the horizontal moving frame 2 enables the first support ring 3 to rotate flexibly, thereby driving the raw material oil lance 5 to make precise angle adjustments. Even if the insertion port of the reaction furnace has a slight positional deviation due to thermal expansion and contraction, the first support ring 3 can be quickly adjusted by operation to align the raw material oil lance 5 to the accurate alignment angle, further improving the alignment accuracy and keeping the error of inserting the raw material oil lance 5 into the reaction furnace insertion port within a smaller range. The articulated cooperation of the elastic telescopic rod 6 with the second support ring 4 and the horizontal moving frame 2 can adjust the position of the second support ring 4 according to the change in the position of the reaction furnace insertion port, and cooperate with the first support ring 3 to ensure that the raw material oil lance 5 always maintains an accurate alignment state throughout the insertion process. This multi-component collaborative adaptive adjustment mechanism effectively overcomes the influence of the change in the insertion port position of the reaction furnace caused by temperature changes on the alignment of the spray gun, greatly improving the accuracy and stability of the alignment.

[0049] The horizontal moving frame 2, the first support ring 3, the second support ring 4, and the elastic telescopic rod 6 form a stable structural system through the hinge connection of the ball head and the ball groove. During the process of inserting the raw material oil lance 5 into the reaction furnace insertion port, the hinge connections between the components can effectively disperse and bear the forces from different directions, avoiding deformation or damage of the device caused by excessive local stress, thereby enhancing the overall stability of the device.

[0050] The elastic support function of the elastic telescopic rod 6 can not only adapt to the change in the position of the reaction furnace insertion port but also play a role in buffering and shock absorption for the raw material oil lance 5. When the device is affected by external vibrations or factors such as pressure fluctuations inside the reaction furnace, the elastic telescopic rod 6 can absorb part of the energy, reduce the impact on the raw material oil lance 5 and other components, and further improve the stability of the device under complex working conditions, ensuring its long-term stable operation.

[0051] The flexible hinge and elastic telescopic design of the device enable it to adapt to reaction furnaces with different conditions and different thermal expansion and contraction characteristics. Whether it is a newly installed reaction furnace or a reaction furnace that has been used for a long time, whether it is a reaction furnace at room temperature at the beginning of heating or a reaction furnace at 1200°C - 1500°C during heating, it can accurately align the raw material oil lance 5 to the insertion port through a convenient operation adjustment method without large-scale modification or replacement of components of the device, improving the versatility and production adaptability of the device.

[0052] During the carbon black production process, process parameters such as the temperature and pressure of the reaction furnace may fluctuate, resulting in varying degrees of changes in the position of the insertion port. This device can respond to these changes in real time, automatically adjust the position of the raw material oil lance 5, ensure that the production process is not affected, improve the continuity and stability of production, reduce the number of production interruptions caused by changes in the working conditions of the reaction furnace, and improve production efficiency.

[0053] The articulated structure of the ball head and the ball groove is relatively simple. During the device maintenance process, if wear or failure is found in a certain articulated part, it can be easily disassembled and replaced. For example, when the first ball head 202 or the first ball groove 301 is worn, only the relevant components need to be disassembled, and after replacing with new components, reinstall them. The operation is relatively simple, reducing the maintenance cost and maintenance time.

[0054] The telescopic property of the elastic telescopic rod 6 enables the position of the second support ring 4 to be easily adjusted during installation and commissioning to adapt to the positions of different reaction furnace insertion ports. The operator can, according to the actual situation, operate the raw material oil lance 5 to change the telescopic length of the elastic telescopic rod 6, quickly adjust the raw material oil lance 5 to the appropriate alignment position, improving the installation and commissioning efficiency of the device.

[0055] In some examples, such as Figures 3 - 7 shown, the structure of the raw material oil lance itself is further optimized to achieve smoother and more accurate insertion into the reaction furnace insertion port, thus solving problems such as alignment deviation and insertion difficulties that may be encountered during the insertion process, ensuring that the raw material oil lance can be efficiently and accurately inserted into the reaction furnace under different working conditions, thus guaranteeing the smooth progress of carbon black production.

[0056] The lance tip 501, as the core of the raw material oil lance 5, is designed in shape to adapt to the oil injection requirements inside the reaction furnace. Usually, the end has a chamfer, and the chamfer is more conducive to insertion into the insertion port.

[0057] The receiving grooves 502 are arranged circumferentially and evenly on the lance tip 501. The number is determined according to the size of the lance tip 501 and the actual requirements, generally 3 - 6. The receiving grooves 502 are parallel to the axial direction of the lance tip 501, and their shape is a rectangular groove. The width and depth of the groove are adapted to the size of the guide member 503. For example, the groove width may be designed to be 10 - 15 mm, and the groove depth is 20 - 30 mm, which can not only ensure the smooth sliding of the guide member 503 in the groove but also provide sufficient support when the guide member 503 slides out. The inner wall of the receiving groove 502 is finely polished with a low surface roughness to reduce the friction force when the guide member 503 slides.

[0058] The guide 503 is designed to be in a rectangular block shape matching the receiving groove 502, with one end being a sliding part matching the receiving groove 502 and the other end being a guiding part. The ends of the guiding part are designed to be conveniently inserted into the insertion port of the reaction furnace. When the guide 503 slides out of the receiving groove 502, these ends can be guided to flip at a certain angle under the action of the first elastic member 505 to achieve these ends approaching each other, thereby facilitating insertion into the insertion port of the reaction furnace. The length of the guide 503 is slightly smaller than the depth of the receiving groove 502 to ensure that it has sufficient protruding length for guiding when sliding out of the receiving groove 502, while not being too long to affect the sliding in the receiving groove 502.

[0059] The push part 504 is arranged on one side of the guide 503 near the root of the gun head 501. It can be a block structure protruding from the side of the guide 503, or a curved spring sheet structure, and its material is the same or similar to that of the guide 503. When the crude oil gun 5 is close to the insertion port of the reactor, the push part 504 first contacts the outer furnace wall of the reactor. As the crude oil gun 5 continues to be inserted, the outer furnace wall exerts an inward thrust on the push part 504, and this thrust overcomes the elastic force of the first elastic member 505, so that the guide 503 is pushed back into the receiving groove 502. The size and shape of the push part 504 are designed according to the shape and position of the outer furnace wall of the reactor, ensuring that it can accurately contact the outer furnace wall during the insertion process and produce an effective pushing effect.

[0060] The first elastic member 505 is a high temperature resistant compression spring, one end of which is tightly fixed on the groove wall at the bottom of the receiving groove 502, and the other end is in contact with the bottom of the guide member 503. The elastic coefficient of the spring is selected according to actual needs, which is required to ensure that it can provide sufficient elastic force to make the guide member 503 slide out of the receiving groove 502 when there is no external force, and to ensure that it can be compressed when the push part 504 is pushed by the external furnace wall, so that the guide member 503 can slide back to the receiving groove 502 smoothly. When installing the first elastic member 505, it is necessary to ensure that the elastic force can act evenly on the guide member 503, so that the guide member 503 can slide smoothly in the receiving groove 502.

[0061] Before the crude oil gun 5 approaches the reactor insertion port, the first elastic member 505 is in a naturally stretched state, providing an outward elastic force for the guide member 503, so that the guide member 503 slides out of the receiving groove 502, and its ends gather toward the middle to form a tip structure that is easy to insert. When the crude oil gun 5 begins to be inserted into the reactor insertion port, the gathered ends of the guide member 503 can better align with the insertion port, play a guiding role, and reduce deviation during the insertion process.

[0062] As the raw material oil lance 5 is further inserted, the pushing part 504 comes into contact with the outer furnace wall of the reaction furnace, and the outer furnace wall exerts a thrust on the pushing part 504. This thrust overcomes the elastic force of the first elastic member 505, causing the guiding member 503 to be gradually pushed back into the receiving groove 502. When the raw material oil lance 5 is completely inserted into the reaction furnace, the guiding member 503 is fully received within the receiving groove 502, without affecting the normal spraying of the raw material oil from the lance tip 501.

[0063] When it is necessary to pull out the raw material oil lance 5, the first elastic member 505 comes into play again. As the lance tip 501 gradually leaves the reaction furnace, the thrust exerted on the pushing part 504 by the outer furnace wall disappears, and the first elastic member 505 returns to its natural extended state, pushing the guiding member 503 out of the receiving groove 502 again to prepare for the next insertion.

[0064] The design of the guiding member 503 where the ends converge towards the middle when sliding out forms a guiding structure similar to an arrow, which can more accurately align with the insertion port of the reaction furnace, effectively reducing the insertion difficulty caused by position deviation of the insertion port or slight deviation of the lance tip 501. In actual production, the insertion accuracy can be improved, greatly reducing the repeated operations due to inaccurate insertion and improving the production efficiency.

[0065] The sliding of the guiding member 503 within the receiving groove 502 and its cooperation with the first elastic member 505 enable the lance tip 501 to adapt to the shape and position changes of the insertion port during the insertion process, further improving the insertion accuracy and stability, ensuring that the raw material oil lance 5 can be smoothly inserted into the reaction furnace and guaranteeing the continuity of carbon black production.

[0066] The interaction between the pushing part 504 and the outer furnace wall enables the guiding member 503 to slide back into the receiving groove 502 during the insertion process, avoiding possible interference and collision between the guiding member 503 and the insertion port or the furnace wall, making the insertion process smoother. This pushing and retracting design reduces the resistance during the insertion process, reduces the risk of damage to the lance tip 501 and the insertion port of the reaction furnace, and extends the service life of the equipment.

[0067] The elastic action of the first elastic member 505 not only makes the guiding member 503 extend to provide guidance before insertion, but also makes the guiding member 503 extend again when pulling out to prepare for the next insertion. The whole process requires no manual intervention, realizing the automation and smoothness of the insertion and pulling out processes.

[0068] Under different production conditions, such as changes in the internal pressure of the reaction furnace and temperature fluctuations, the design of the first elastic member 505 and the guiding member 503 can ensure that the insertion performance of the lance tip 501 is not affected, ensuring that the device can operate stably under various complex conditions and improving the reliability of production.

[0069] The structures of the guiding member 503, the pushing portion 504, and the first elastic member 505 are relatively simple, and they are easy to disassemble and install. If a certain component is damaged or worn, it can be conveniently replaced, reducing the maintenance cost and difficulty. For example, when the first elastic member 505 loses its elasticity, it can be simply taken out from the receiving groove 502 and a new spring can be replaced, with simple and quick operation.

[0070] The working process of the entire structure has a high degree of automation. There is no need for operators to perform complex operations. Only the insertion and extraction actions of the raw material oil lance 5 need to be controlled, improving the operation convenience and production efficiency.

[0071] In some examples, such as Figure 7 shown, the structures of the receiving groove and the guiding member are further optimized. By providing a guiding groove at the bottom of the receiving groove and designing a guiding portion on the guiding member to cooperate with it, the self-adaptive adjustment ability of the raw material oil lance during insertion is further enhanced, more accurately aligning with the insertion port and solving the insertion problem under complex working conditions.

[0072] The guiding groove 506 is located at the bottom of the receiving groove 502 and is made by precision machining processes such as electric discharge machining or laser cutting to ensure its shape accuracy and surface quality. The guiding groove 506 is composed of a translation section 507 and a torsion section 508 connected to each other.

[0073] The translation section 507 is arranged along the axial direction of the receiving groove 502, and the proportion of its length in the total length of the guiding groove 506 is determined according to actual needs. Its width is slightly larger than the width of the guiding portion 509 of the guiding member 503 to ensure that the guiding portion 509 can slide smoothly within the translation section 507 while restricting the horizontal sway of the guiding portion 509. Ensure that there is sufficient support for the guiding portion 509 during translation.

[0074] The torsion section 508 is inclined relative to the translation section 507, and the inclination angle is usually between 15° - 45°. The specific angle is optimized according to the required torsion effect of the guiding member 503. The length of the torsion section 508 is the remaining part of the total length of the guiding groove 506 and ensures the stability of the guiding portion 509 when sliding within the torsion section 508. The depth of the torsion section 508 is the same as that of the translation section 507 at the end close to the translation section 507, but the angle changes. This angle enables the guiding member 503 to gradually adjust its posture during torsion.

[0075] The guiding part 509 is located at the bottom of the guiding member 503 and is adapted to the guiding groove 506. The guiding part 509 is made of the same material as the guiding member 503 and is manufactured by an integral molding process to ensure its connection strength with the guiding member 503. The shape of the guiding part 509 is designed according to the shape of the guiding groove 506. At the part where it cooperates with the translation section 507, the guiding part 509 is in the shape of a rectangular block, its width is adapted to the width of the translation section 507, and its length is less than the length of the translation section 507 to ensure smooth sliding within the translation section 507. At the part where it cooperates with the torsion section 508, when the guiding part 509 turns to the torsion section 508, the angle of the guiding part 509 changes to cause the guiding member 503 to twist within the torsion section 508, so that its end part converges towards the middle to form a tip structure convenient for insertion.

[0076] When the raw material oil lance 5 is ready to be inserted into the insertion port of the reaction furnace, under the action of the first elastic member 505, the guiding member 503 slides outwards along the receiving groove 502, and the guiding part 509 first slides within the translation section 507 of the guiding groove 506, so that the guiding member 503 smoothly extends out of the receiving groove 502, and its end part converges towards the middle to provide guidance for inserting into the insertion port of the reaction furnace.

[0077] During the insertion process, if there are slight deviations in the position or angle of the insertion port of the reaction furnace, the guiding part 509 of the guiding member 503 will gradually twist along with the torsion section 508 of the guiding groove 506. Since the torsion section 508 is inclined relative to the translation section 507, when the guiding part 509 is within the torsion section 508, the tip structure formed by the end part of the lance head 501 converging towards the middle can better align with the insertion port.

[0078] When the pushing part 504 contacts the outer furnace wall of the reaction furnace and receives a thrust, the guiding member 503 starts to retract into the receiving groove 502. The guiding part 509 slides along the torsion section 508 and then slides to the translation section 507 until it completely retracts into the receiving groove 502.

[0079] The design of the torsion section 508 of the guiding groove 506 enables better guidance during the extension process of the guiding member 503, thereby driving the lance head 501 to more accurately align with the insertion port. Compared with the structure without the torsion section 508, the alignment accuracy is improved, effectively reducing problems such as insertion failure or uneven spraying of raw material oil caused by position deviation of the insertion port, and enhancing the quality stability of carbon black production.

[0080] The precise cooperation between the guiding member 503 and the guiding groove 506 enables the lance head 501 to have better adaptive adjustment ability in three-dimensional space, can cope with more complex changes in the position and angle of the insertion port, ensure that the raw material oil lance 5 can be accurately inserted into the reaction furnace under various working conditions, and further improve the reliability of the production process.

[0081] The guiding member 503 can be effectively and adaptively adjusted through the function of the guiding groove 506, which expands the applicable range of the device and improves the compatibility of the device with different reactors. In different production environments and working conditions, such as pressure fluctuations inside the reactor and drastic temperature changes, the coordinated action of the guiding groove 506 and the guiding member 503 can ensure the insertion stability of the gun head 501, ensuring that the raw material oil lance 5 can still be stably and accurately inserted into the reactor under complex conditions, enhancing the environmental adaptability and reliability of the device.

[0082] The adaptive design of the guiding groove 506 and the translation section 507 with the guiding part 509 ensures the smoothness of the guiding member 503 during extension and retraction, reducing jamming and resistance. During insertion and extraction, the guiding member 503 can slide more smoothly within the receiving groove 502, avoiding difficulties in insertion or equipment damage caused by interference between the guiding member 503 and the receiving groove 502, and improving the efficiency and smoothness of the insertion and extraction operations.

[0083] In some examples, such as Figure 7 shown, the position of the torsion section and the connection method between the translation section and the torsion section are further clarified to more precisely control the movement of the guiding member, optimize the alignment process of the gun head, and ensure that the raw material oil lance can be efficiently, stably, and accurately inserted into the reactor under complex and changeable production conditions, improving the overall quality and efficiency of carbon black production.

[0084] The translation section 507 and the torsion section 508 are connected with a smooth transition to ensure that when the guiding part 509 enters the torsion section 508 from the translation section 507 and moves in the reverse direction, it can transition smoothly, avoiding jamming or impact caused by sudden changes. This smooth transition not only ensures the smoothness of the movement of the guiding member 503 but also reduces the wear on the guiding part 509 and the guiding groove 506, extending the service life of the components.

[0085] The smooth transition connection between the translation section 507 and the torsion section 508 ensures that the guiding part 509 is unobstructed during the conversion process, enabling the guiding member 503 to twist smoothly, and enabling the gun head 501 to precisely adapt to the position and angle changes of the insertion port. When the pushing part 504 is pushed by the outer furnace wall of the reactor and the guiding member 503 retracts, the guiding part 509 smoothly slides back into the translation section 507 from the torsion section 508, and the guiding member 503 returns to its initial posture and fully retracts into the receiving groove 502.

[0086] The smooth transition connection between the translation section 507 and the torsion section 508 ensures the coherence and accuracy of the twisting action of the guiding member 503, avoiding angular deviation caused by unsmooth transition, enabling the gun head 501 to accurately align with the insertion port under complex working conditions, and further enhancing the alignment reliability of the device.

[0087] The smooth transition connection effectively reduces the jamming and impact of the guide part 509 during the movement, making the extension and retraction of the guide 503 smoother. This not only improves the efficiency of the insertion and extraction operation, but also reduces the risk of damage to the guide 503, the gun head 501 and the reactor insertion port, thereby extending the service life of the device.

[0088] In some examples, such as Figure 7 As shown, the push part 504 is set as a sliding structure, and a second elastic member 510 is added, which further enhances the adaptability of the crude oil gun during the insertion process, so that it can better cope with the challenges brought by the different positions and shapes of the outer furnace wall of the reactor, ensuring that the insertion process is smoother and more accurate, thereby ensuring the stability and efficiency of carbon black production.

[0089] The shape of the push part 504 is designed to be block-shaped or sheet-shaped, which is determined according to the structure of the guide 503 and actual needs. For example, if the guide 503 is a rectangular block, the push part 504 can be designed to be a rectangular sheet that fits the side of the guide 503 and fits on the side of the guide 503 near the root of the gun head 501. The push part 504 is provided with a slide groove or a slider structure, which cooperates with the corresponding slider or slide groove on the guide 503 to achieve a sliding connection.

[0090] The guide member 503 is optimized for sliding cooperation with the pusher 504. On the side in contact with the pusher 504, a slide groove or a slide block structure matching with the slide block or the slide groove of the pusher 504 is processed.

[0091] One end of the second elastic member 510 is tightly fixed to the side of the pusher 504 close to the guide member 503, and the other end is fixed to the corresponding position of the guide member 503, ensuring that the direction of the elastic force is consistent with the direction of the pusher 504 approaching the outer wall of the reactor. During the installation process, it is necessary to ensure that the axis of the second elastic member 510 is perpendicular to the contact surface between the pusher 504 and the guide member 503 to ensure uniform transmission of the elastic force, so that the pusher 504 can smoothly approach the outer wall of the reactor.

[0092] When the crude oil gun 5 is close to the reactor insertion port, the guide member 503 slides out of the receiving groove 502 under the action of the first elastic member 505, and the ends gather toward the middle. At this time, the second elastic member 510 is in a naturally stretched or slightly compressed state, providing a force for the pusher 504 to approach the reactor outer wall, so that the pusher 504 can be closely attached to the reactor outer wall.

[0093] During the insertion process, if the outer furnace wall surface of the reaction furnace is uneven or has a certain angular change, the pushing part 504 will slide along the guiding part 503 under the elastic force of the second elastic part 510 for adaptive adjustment. For example, when encountering a local protrusion on the outer furnace wall, the pushing part 504 receives a reverse force, compresses the second elastic part 510 and slides along the guiding part 503, avoiding a hard collision with the protrusion part and ensuring a smooth insertion process. At the same time, the sliding of the pushing part 504 can drive the guiding part 503 to finely adjust its position, so that the gun head 501 can better align with the insertion port.

[0094] When the pushing part 504 receives a large enough thrust to overcome the elastic force of the second elastic part 510 and the elastic force of the first elastic part 505, the guiding part 503 begins to retract into the receiving groove 502 to complete the insertion action.

[0095] The cooperation between the sliding structure of the pushing part 504 and the second elastic part 510 enables the large raw material oil gun 5 to better adapt to various shapes and surface conditions of the outer furnace wall of the reaction furnace. Whether there are slight deformations, local protrusions or depressions on the outer furnace wall, or differences in the shapes of the outer furnace walls of different reaction furnaces, the pushing part 504 can closely fit the outer furnace wall through sliding and the elastic adjustment of the second elastic part 510, ensuring the accurate positions of the guiding part 503 and the gun head 501, and improving the versatility and adaptability of the device to different reaction furnaces.

[0096] During the insertion process, for the dynamic changes in the position and shape of the outer furnace wall caused by the thermal expansion and contraction of the reaction furnace, the pushing part 504 and the second elastic part 510 can respond in real time, automatically adjust the position of the pushing part 504, ensure that the retraction action of the guiding part 503 is not affected, and ensure that the large raw material oil gun 5 can be smoothly inserted into the reaction furnace, enhancing the stability of the device under complex working conditions.

[0097] The continuous elastic force provided by the second elastic part 510 keeps the pushing part 504 in good contact with the outer furnace wall of the reaction furnace all the time, avoiding the position deviation of the guiding part 503 caused by the separation or poor contact between the pushing part 504 and the outer furnace wall, so as to ensure that the gun head 501 always aligns with the insertion port during the insertion process and improve the accuracy of insertion.

[0098] The sliding structure of the pushing part 504 can buffer the impact force during the insertion process, reduce the vibration and damage caused to the guiding part 503 and the gun head 501 by the unevenness or angular change of the outer furnace wall, make the insertion process smoother, reduce the risk of equipment damage, and extend the service life of the large raw material oil gun 5.

[0099] The sliding connection between the pushing part 504 and the guiding part 503, along with the elastic support of the second elastic part 510, forms a stable adaptive system. During the insertion process, even when encountering external interference or internal pressure fluctuations in the reactor, this system can maintain the stable insertion of the raw material oil lance 5 through self-adjustment, avoiding the deviation of the lance tip 501 from the insertion port due to external forces, and enhancing the stability and reliability of the device in complex production environments.

[0100] The presence of the second elastic part 510 makes the force on the pushing part 504 more uniform, reduces component damage caused by excessive local force, further improves the overall stability of the device, and reduces maintenance costs and downtime.

[0101] In some examples, such as Figure 7 shown, an insertion rod 511 and a third elastic part 512 are further added to the head of the guiding part, further enhancing the guiding and adaptive capabilities of the raw material oil lance when inserting into the insertion port of the reactor, ensuring that when facing insertion ports of different sizes, shapes, and working conditions, the insertion operation can be completed more efficiently and accurately, thereby ensuring the stability and efficiency of carbon black production.

[0102] The insertion rod 511 is designed in the shape of a long rod. One end is a hinged end hinged to the guiding part 503, and the other end is an insertion end. The end of the insertion end can be designed as a conical shape or a wedge shape to facilitate easier entry into the insertion port. The hinged end of the insertion rod 511 is connected to the head of the guiding part 503 through a small hinge shaft. The insertion rod 511 rotates flexibly within a specified angle range. To prevent the hinge shaft from loosening during use, snap rings or nuts can be set at both ends of the hinge shaft for fixation.

[0103] The third elastic part 512 can be selected as a torsion spring. The two ends of the torsion spring are respectively connected to the insertion rod 511 and the guiding part 503. During installation, the torsion spring is sleeved on the hinge shaft, with one end fixed at a specific position near the hinged end of the insertion rod 511, and the other end fixed at the corresponding position on the head of the guiding part 503. In this way, when there is no external force, the torsion spring is in a natural state, providing a torsion force for the insertion rod 511 to keep an included angle of 150 degrees with the guiding part 503. This angle design not only helps the insertion rod 511 to enter the insertion port first to play a guiding role, but also ensures coordinated work with the guiding part 503 to provide stable guidance for the insertion of the lance tip 501.

[0104] When the raw material oil lance 5 approaches the insertion port of the reactor, under the action of the first elastic part 505, the guiding part 503 slides out of the receiving groove 502, and the ends gather towards the middle. At this time, under the action of the third elastic part 512, the insertion rod 511 and the guiding part 503 maintain an included angle of 150 degrees.

[0105] During the insertion process, the conical or wedge-shaped end of the insertion rod 511 first contacts the insertion opening. The insertion rod 511 can be more easily aligned and enter the insertion opening, playing a guiding role. If the size or shape of the insertion opening is somewhat different from the expectation, the insertion rod 511 may be subjected to a lateral force when entering the insertion opening. When the lateral force is large enough, the insertion rod 511 will overcome the torsion force of the third elastic member 512 and rotate around the hinge axis, increasing the angle between the insertion rod 511 and the guiding member 503, but not exceeding 180 degrees at most. This rotation enables the insertion rod 511 to better adapt to the actual situation of the insertion opening and continue to guide the insertion of the gun head 501.

[0106] When the pushing part 504 is subjected to the thrust of the outer furnace wall of the reactor and the guiding member 503 starts to retract into the receiving groove 502, the insertion rod 511 will also retract together with the guiding member 503. During the retraction process, the third elastic member 512 always maintains the torsion force on the insertion rod 511 to ensure that the angle between it and the guiding member 503 is maintained within a suitable range so that it can quickly return to the best guiding state during the next insertion.

[0107] The setting of the insertion rod 511 provides a more accurate guide for the gun head 501 to enter the insertion opening. The shape of its end and the 150-degree angle maintained with the guiding member 503 enable it to more accurately align with the insertion opening at the initial stage of insertion, effectively reducing the insertion difficulty caused by the position deviation of the insertion opening or the slight deviation of the gun head 501. Compared with the situation where the insertion rod 511 is not set, the insertion accuracy is improved, greatly reducing the repeated operations due to inaccurate insertion and improving the production efficiency.

[0108] The guiding role of the insertion rod 511 makes the process of the gun head 501 entering the insertion opening smoother. Its conical or wedge-shaped end can effectively push aside the impurities or slight obstacles that may exist in the insertion opening, and at the same time adapt to the irregular shape of the insertion opening through angle adjustment during the insertion process, reducing the jamming and resistance during the insertion process, avoiding damage to the gun head 501 and the insertion opening caused by forced insertion, and extending the service life of the equipment.

[0109] In some examples, such as Figure 2 shown, the first, second, and third locking bolts are added to further optimize the device performance, enhance the stability and reliability of each hinged part, ensure the firm connection between the device components under harsh production environments such as high temperature and vibration, maintain the accurate alignment and insertion functions, and guarantee the high efficiency and stability of carbon black production.

[0110] The first locking bolt 7 is installed on the side wall of the first ball groove 301. After the first ball head 102 is hinged and installed in the first ball groove 301, the first locking bolt 7 is screwed into the threaded hole so that its end abuts against the first ball head 102. By tightening the first locking bolt 7, the tightness of the first ball head 102 in the first ball groove 301 can be adjusted. When the device is running normally, moderately tightening the bolt can limit the excessive rotation of the first ball head 102, ensure that the first support ring 3 stably supports the raw material oil lance 5 within a certain range, and enhance the overall stability of the device.

[0111] For example, when the raw material oil lance 5 is inserted into the insertion port of the reaction furnace to spray the raw material oil into the reaction furnace for carbon black production, the first locking bolt 7 can be operated to lock the first ball head 202 on the first ball groove 301, which can prevent the first ball head 102 from shaking in the first ball groove 301 and ensure the support stability of the raw material oil lance 5. By locking the second ball head 601 on the second ball groove 103 through the second locking bolt 8, it can ensure that the elastic telescopic rod 6 can accurately transmit the telescopic force and maintain the support stability of the raw material oil lance 5. By locking the third ball head 602 on the third ball groove 401 through the third locking bolt 9, it can ensure that the elastic telescopic rod 6 can accurately transmit the telescopic force, maintain the support stability of the raw material oil lance 5, and cooperate with the first support ring 3 to maintain the accurate alignment and insertion of the raw material oil lance 5.

[0112] The settings of the first, second, and third locking bolts significantly improve the connection stability of each hinged part. In harsh production environments such as high temperature and vibration, it can effectively prevent loosening, displacement, or excessive rotation between the ball head and the ball groove, ensuring the overall structural stability of the device. For example, in the case where the temperature near the reaction furnace is as high as several hundred degrees Celsius and accompanied by strong vibration, the device can still maintain the stable support and alignment of the raw material oil lance 5, greatly reducing the risk of alignment deviation and equipment damage caused by component loosening.

[0113] In some examples, as Figures 1 - 2 shown, a fourth locking bolt is added to further optimize the device performance, enhance the stability of the horizontal moving frame, prevent unnecessary movement during the operation of the device due to various external forces, thereby ensuring the accuracy and reliability of the raw material oil lance during alignment and insertion, and ensuring the smooth progress of carbon black production.

[0114] The fourth locking bolt 10 is installed at the contact part between the horizontal moving frame 2 and the support frame 1. Specifically, threaded holes are machined at the bottom or side of the horizontal moving frame 2. During installation, the fourth locking bolt 10 is installed on the threaded hole of the horizontal moving frame 2, and by tightening the fourth locking bolt 10, the horizontal moving frame 2 can be locked relative to the support frame 1. The operator moves the horizontal moving frame 2 to a suitable position through the driving mechanism of the horizontal moving frame 2 according to the position of the reactor insertion port, so that the raw material oil lance 5 is initially aligned with the reactor insertion port. Then, the operator uses a tool to tighten the fourth locking bolt 10 to firmly lock the horizontal moving frame 2 on the support frame 1.

[0115] During the operation of the device, even affected by external vibrations, pressure fluctuations inside the reactor and other factors, due to the locking force provided by the fourth locking bolt 10, the horizontal moving frame 2 will not move accidentally, thus ensuring the position stability of the raw material oil lance 5 relative to the reactor insertion port. This helps to maintain the alignment accuracy of the raw material oil lance 5 and ensures that it can accurately insert into the reactor insertion port.

[0116] The setting of the fourth locking bolt 10 effectively prevents the accidental movement of the horizontal moving frame 2 during the operation of the device. At the carbon black production site, vibrations will occur when the reactor is running, and at the same time, there may be interference from other equipment in the surrounding environment, and these factors may cause the horizontal moving frame 2 to displace.

[0117] In some examples, as Figure 1 shown, an operating handle 11 is added to further optimize the operation convenience of the device, providing a convenient operation method for the operator during equipment debugging, maintenance and manual intervention in special situations, ensuring that the device can operate efficiently under various conditions and guaranteeing the smooth progress of carbon black production.

[0118] The operating handle 11 is installed at one end of the raw material oil lance 5 away from the lance tip 501, and can be specifically installed on the side or top of the raw material oil lance 5. When installed on the side, it is convenient for the operator to grasp from the side and is suitable for fine-tuning operations in the horizontal direction; when installed on the top, it more conforms to the operation habit of pulling or pressing in the vertical direction. The specific installation position can be selected according to the actual operation scenario and the operator's usage habit.

[0119] During the device debugging stage, the operator can manually adjust the position of the raw material oil lance 5 by grasping the operating handle 11. For example, when the automatic alignment system initially moves the raw material oil lance 5 near the reactor insertion port, the operator can make fine horizontal or vertical adjustments through the operating handle 11 to make the lance tip 501 more accurately aligned with the insertion port.

[0120] During the maintenance process, the operator can conveniently move the heavy oil gun 5 of the raw material oil by means of the operating handle 11, so as to inspect, clean or replace components such as the gun head 501 and the guiding member 503. For example, when it is necessary to check whether the guiding member 503 is worn, the operator can hold the operating handle 11 and move the heavy oil gun 5 of the raw material oil to an appropriate position from the support frame 1, which is more convenient for observation and operation.

[0121] In special cases, such as when the automatic alignment device fails, the operator can manually insert the heavy oil gun 5 of the raw material oil into the insertion port of the reaction furnace through the operating handle 11 to ensure the continuity of production. With the good grip and controllability provided by the operating handle 11, the operator inserts the gun head 501 into the insertion port as accurately as possible.

[0122] In some examples, a two-dimensional scale can also be set and installed on the reaction furnace and on one side of the insertion port, and a laser emitter is installed on the heavy oil gun 5 of the raw material oil. When adjusting the position of the heavy oil gun 5 of the raw material oil, it is possible to judge whether the heavy oil gun 5 of the raw material oil is aligned with the insertion port of the reaction furnace according to the horizontal and vertical coordinates of the laser spot of the laser emitter on the two-dimensional scale. For example, in the cold state of the reaction furnace, adjust the heavy oil gun 5 of the raw material oil to move in and out normally without jamming, and then use laser marking to record the corresponding dimensions. Before the reaction furnace heats up to the normal state, use laser marking again to check the displacement dimensions of the reaction furnace and make adjustments to ensure that the heavy oil gun 5 of the raw material oil can also move in and out normally in the hot state. After using the laser ruler and the on-site scale, make data records after the equipment is debugged normally in the cold state, and perform secondary calibration after the furnace body is in the hot state to ensure that the heavy oil gun 5 of the raw material oil can move in and out freely to find the most suitable insertion position.
