Description

Technical Field

[0001] The present application belongs to the technical field of reactor feed for carbon black production, and specifically relates to a reactor feed device for producing high-pigment specialty carbon black. Background Art

[0002] The reactor feeding device for the production of high-pigment specialty carbon black is a device for conveying raw materials to the reactor in the carbon black production system. Its main function is to accurately, stably and evenly convey the raw materials required for the preparation of carbon black to the reactor to ensure efficient reaction and stable product quality.

[0003] For example, the publication number: CN206580762U discloses a multi-angle feeding reaction throat of a carbon black reactor, which belongs to the technical field of chemical production equipment. The technical solution of the utility model is: a multi-angle feeding reaction throat of a carbon black reactor, comprising: a combustion section, a multi-angle nozzle, a tapered guide section, and a reaction section. The multi-angle feeding reaction throat of the carbon black reactor is sequentially connected with the combustion section, the tapered guide section, the reaction section, the quenching section, and the buffer section. A normally closed reaction throat inspection port is provided on the left side of the combustion section, and at least three multi-angle nozzles are provided on the side wall of the combustion section. The multi-angle nozzle is at a 45° angle to the side wall of the combustion section, and the combustion section is connected to the reaction section through the tapered guide section. The end of the buffer section is provided with a carbon black smoke outlet. It has the advantages of high efficiency, stability, ease of use, multi-angle feeding, uniform distribution of combustion raw materials, and improved quality of carbon black products.

[0004] However, the feed device in this application lacks a roller shutter to regulate heat dissipation within the preheating structure. This can lead to uncontrolled heat dissipation into the surrounding environment, making it difficult to maintain a stable temperature within the appropriate range during the preheating process, and potentially causing large temperature fluctuations. For example, when heating the raw materials, if the external ambient temperature is low or there is airflow, heat will dissipate rapidly, making it impossible for the raw materials to continuously and stably reach the required preheating temperature, thereby affecting the stability of the carbon black production reaction within the reactor, and resulting in unstable carbon black product quality, such as uneven particle size distribution. Utility Model Content

[0005] The purpose of this application is to provide a reactor feeding device for the production of high-pigment specialty carbon black in order to solve the above-mentioned product quality problems.

[0006] The technical solution adopted in this application is as follows: a reactor feeding device for the production of high-pigment special carbon black, comprising a base plate, the upper surface of the base plate is fixedly connected to a connecting plate, the inner two sides of the connecting plate are fixedly connected to heating tubes, the two sides of the connecting plate are fixedly connected to a rolling shutter frame, a groove opened on one side of the rolling shutter frame is provided with a sliding rod, the outer surface of the sliding rod is slidably connected to a slider, and one side of the slider is fixedly connected to a rolling shutter plate.

[0007] By implementing the above technical solution, a preheating structure with a rolling shutter door has been added to the feed system of the reactor for high-pigment specialty carbon black production. The operator controls the shutter door by sliding the shutter plate on a slide bar by gripping a slider. The shutter door can be flexibly opened and closed. By adjusting the shutter door's opening, the heat dissipation within the preheating structure can be precisely controlled, thereby precisely adjusting the temperature of the raw materials being heated. For example, when the raw materials need to be preheated to a specific temperature range to meet optimal reaction conditions within the reactor, the shutter door opening can be adjusted based on temperature monitoring to maintain the desired temperature, ensuring stable carbon black production reactions and consistent product quality. Heat loss is inevitable during the preheating process, but the shutter door can significantly reduce this loss. When the raw materials are heated within the preheating structure, closing the shutter door creates a relatively enclosed space, effectively preventing heat from dissipating into the surrounding environment, acting as a "thermal barrier" for the preheating area. Compared with open or ordinary closed preheating structures without roller shutters, it can significantly reduce heat loss and improve energy utilization efficiency, thereby reducing the energy consumption cost of carbon black production. The presence of roller shutters helps maintain a relatively stable thermal environment within the preheating structure. When the roller shutters are closed, the flow of hot air inside is relatively smooth and regular, allowing the raw materials to be heated more evenly during the preheating process. This is particularly important for the production of high-pigment specialty carbon black, because after the evenly heated raw materials enter the reactor, they can react more evenly in the reactor, which helps to improve the quality stability of carbon black products and reduce product quality fluctuations caused by uneven heating of the raw materials, such as uneven carbon black particle size distribution, unstable pigment properties and other problems.

[0008] In a preferred embodiment, a control panel is fixedly connected to the upper surface of the base plate, and a storage bin is fixedly connected to the upper surface of the base plate.

[0009] By adopting this technical solution, operators can precisely set and adjust various operating parameters of the feeding device through the control panel, such as the rotational speed of screw pumps A and B, the feeder speed, and the conveyor belt speed. This ensures that the raw materials are accurately delivered to the reactor according to the predetermined flow rate, speed, and time, ensuring that the chemical reaction within the reactor proceeds under optimal conditions, helping to improve the quality and production efficiency of carbon black products. The storage silo provides a centralized storage location for raw materials in carbon black production, ensuring a continuous supply of sufficient raw materials throughout the production process. Its capacity can be designed according to the production scale, allowing it to reserve a certain amount of raw materials to avoid production interruptions caused by interruptions in the raw material supply.

[0010] In a preferred embodiment, a screw pump A is provided on one side of the storage bin, and an input pipe is provided on one end of the screw pump A relative to the storage bin.

[0011] By adopting the above technical solution, Screw Pump A can extract raw materials from the storage silo and transport them to subsequent stages at a relatively stable flow rate and pressure. Its operating principle is based on the rotation of the screw to form a sealed chamber to propel the raw materials forward. This method of transportation is relatively stable and less prone to large fluctuations in flow rate, thus ensuring the stability of the flow rate of raw materials entering the reactor, which is crucial for maintaining the balance and stability of the chemical reactions within the reactor. The inlet pipe serves as a channel connecting Screw Pump A to other components, ensuring the smooth flow of raw materials between various devices. It enables the smooth transfer of raw materials from the output end of Screw Pump A to the next processing stage, ensuring the continuity and integrity of the entire feeding device, and is a key link in achieving orderly raw material transportation.

[0012] In a preferred embodiment, a fixed clamping plate is fixedly connected to the upper surface of the bottom plate, and a feeder is provided on one side of the fixed clamping plate.

[0013] By employing this technical solution, the fixed clamps primarily secure and support the feed tubes in the feeder, ensuring they do not shift or wobble during operation due to vibration, external impact, or other factors. The feeder precisely controls the amount of raw material delivered to the reactor based on production process requirements. By adjusting parameters such as feed rate and opening, it fine-tunes the raw material flow rate, ensuring that the amount entering the reactor meets the optimal ratio and reaction conditions for carbon black production. This is crucial for improving the quality and consistency of carbon black products.

[0014] In a preferred embodiment, a belt conveyor is fixedly connected to the upper surface of the base plate, and a fan connecting plate is fixedly connected to the upper surface of the base plate.

[0015] By employing the above-mentioned technical solution, a belt conveyor can achieve efficient and continuous transportation of raw materials. Its rotational belt continuously transports raw materials from the feeder to the next stage. Its primary function is to connect the blower with the other components of the feeding system, forming an integrated whole. This ensures the blower can work in conjunction with other equipment, providing a stable connection foundation for subsequent operations and ensuring the coherence and coordination of the entire feeding system. The preheated raw materials may contain some moisture that evaporates more easily due to the increased temperature.

[0016] In a preferred embodiment, a plurality of blowers are provided at both ends of the inner side of the blower connecting plate.

[0017] By adopting the above technical solution, the airflow blown out by the hair dryer can accelerate the evaporation of water, further reduce the moisture content of the raw materials, and effectively prevent the raw materials from agglomerating due to moisture during subsequent transportation, storage or after entering the reactor.

[0018] In a preferred embodiment, a fixed box is provided on one side of the belt conveyor, and a screw pump B is provided on one side of the fixed box.

[0019] By employing this technical solution, the fixed tank temporarily holds the raw materials after preheating, dehydration, and storage, ensuring the integrity and stability of the overall structure and becoming a crucial component. Screw Pump B functions similarly to Screw Pump A, delivering the blow-dried raw materials to the output pipe at a stable flow rate and pressure. Its stable delivery performance ensures a continuous and smooth flow of raw materials into the reactor, maintaining the stability of the chemical reaction within the reactor and playing a crucial role in safeguarding the quality and production efficiency of carbon black products.

[0020] In a preferred embodiment, the screw pump B is provided with an output pipe at one end relative to the fixed box.

[0021] By adopting this technical solution, the output pipe serves as the final channel for conveying the raw materials delivered by screw pump B to the reactor, ensuring smooth entry of the raw materials into the reactor for chemical reaction. It is the key link between the entire feeding device and the reactor, achieving seamless connection of raw materials from the feeding device to the reactor and ensuring the continuity of the carbon black production process.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, a preheating structure with a rolling shutter door is added to the feeding device of the reactor for the production of high-pigment specialty carbon black, wherein the operator can slide the rolling shutter plate on the slide rod by holding the slider, thereby controlling the closing of the rolling shutter door. The rolling shutter door can be opened and closed flexibly, and by adjusting the opening of the rolling shutter door, the degree of heat dissipation inside the preheating structure can be accurately controlled, thereby accurately adjusting the temperature at which the raw materials are heated. For example, when the raw materials need to be preheated to a specific temperature range to meet the optimal reaction conditions in the reactor, the opening of the rolling shutter door can be adjusted in time according to the temperature monitoring situation to stabilize the raw materials at the required temperature, thereby ensuring the stability of the carbon black production reaction and the consistency of product quality. During the preheating process, heat loss is inevitable, but the rolling shutter door can reduce this loss to a great extent.

[0024] When the raw materials are heated in the preheating structure, closing the roller shutter door can form a relatively closed space, effectively preventing the diffusion of heat to the surrounding environment, just like adding a "heat-insulating barrier" to the preheating area. Compared with open or ordinary closed preheating structures without roller shutters, it can significantly reduce heat loss, improve energy efficiency, and thus reduce the energy consumption cost of carbon black production. The presence of the roller shutter door helps to maintain a relatively stable thermal environment in the preheating structure. When the roller shutter door is closed, the flow of hot air inside is relatively smooth and regular, allowing the raw materials to be heated more evenly during the preheating process. This is particularly important for the production of high-pigment specialty carbon black, because after the evenly heated raw materials enter the reactor, they can react more evenly in the reactor, which helps to improve the quality stability of the carbon black product and reduce product quality fluctuations caused by uneven heating of the raw materials, such as uneven carbon black particle size distribution, unstable pigment properties and other problems.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] Example:

[0033] Reference Figure 1-3 A connecting plate 2 is fixedly connected to the top surface of the base plate 1. Heating tubes 3 are fixedly connected to the interior sides of the connecting plate 2. A rolling shutter frame 4 is fixedly connected to both sides of the connecting plate 2. A sliding rod 5 is provided in a groove on one side of the rolling shutter frame 4. A slider 6 is slidably connected to the outer surface of the slider 5. A rolling shutter plate 7 is fixedly connected to one side of the slider 6. A preheating structure with a rolling shutter door has been added to the feed device of the reactor for producing high-pigment specialty carbon black. The operator can slide the rolling shutter plate 7 along the slider 5 by holding the slider 6, thereby controlling the closing of the rolling shutter door. The rolling shutter door can be opened and closed flexibly. By adjusting the opening of the rolling shutter door, the degree of heat dissipation within the preheating structure can be precisely controlled, thereby accurately adjusting the temperature of the heated raw materials. For example, when the raw materials need to be preheated to a specific temperature range, such as 200-300°C, to meet optimal reaction conditions in the reactor, the opening of the rolling shutter door can be adjusted in a timely manner based on temperature monitoring to stabilize the raw materials at the required temperature, ensuring the stability of the carbon black production reaction and consistent product quality. During the preheating process, heat loss is inevitable, but a rolling door can significantly reduce this loss. When the raw materials are heated within the preheating structure, closing the rolling door creates a relatively enclosed space, effectively preventing heat from escaping to the surrounding environment, like adding a "heat-insulating barrier" to the preheating area.

[0034] Compared with open or ordinary closed preheating structures without roller shutters, it can significantly reduce heat loss and improve energy utilization efficiency, thereby reducing the energy consumption cost of carbon black production. The presence of roller shutters helps maintain a relatively stable thermal environment within the preheating structure. When the roller shutters are closed, the flow of hot air inside is relatively smooth and regular, allowing the raw materials to be heated more evenly during the preheating process. This is particularly important for the production of high-pigment specialty carbon black, because after the evenly heated raw materials enter the reactor, they can react more evenly in the reactor, which helps to improve the quality stability of carbon black products and reduce product quality fluctuations caused by uneven heating of the raw materials, such as uneven carbon black particle size distribution, unstable pigment properties and other problems.

[0035] Reference Figure 1-2 , a control panel 8 is fixedly connected to the upper surface of the bottom plate 1, and a storage silo 9 is fixedly connected to the upper surface of the bottom plate 1. Through the control panel 8, the operator can accurately set and adjust the various operating parameters of the feeding device, such as the rotation speed of screw pump A and screw pump B, the feeding speed of the feeder, the conveying speed of the belt conveyor, etc. This enables the raw materials to be accurately delivered to the reactor according to the predetermined flow rate, speed and time, ensuring that the chemical reaction in the reactor proceeds according to the optimal conditions, which helps to improve the quality and production efficiency of carbon black products. The storage silo 9 provides a place for centralized storage of raw materials for carbon black production, ensuring that there is a continuous supply of sufficient raw materials during the production process. Its capacity can be designed according to the scale of production, and it can reserve a certain amount of raw materials to avoid production stagnation due to interruption of raw material supply.

[0036] Reference Figure 1 , Figure 4 , a screw pump A 10 is provided on one side of the storage bin 9, and an input pipe 11 is provided on one end of the screw pump A 10 relative to the storage bin 9. The screw pump A 10 can extract the raw materials in the storage bin at a relatively stable flow rate and pressure and transport them to the subsequent links. Its working principle is based on the rotation of the screw to form a sealed chamber to push the raw materials forward. This transportation method is relatively stable and not prone to large fluctuations in flow rate, thereby ensuring the flow stability of the raw materials entering the reactor, which is very important for maintaining the balance and stability of the chemical reaction in the reactor. The input pipe 11 serves as a channel connecting the screw pump A with other components such as feeders. The input pipe 11 ensures that the raw materials can flow smoothly between various devices. It enables the raw materials to be smoothly transmitted from the output end of the screw pump A to the next processing link, ensuring the continuity and integrity of the entire feeding device, and is a key link in achieving orderly transportation of raw materials.

[0037] Reference Figure 4 , a fixed clamping plate 12 is fixedly connected to the upper surface of the bottom plate 1, and a feeder 13 is provided on one side of the fixed clamping plate 12. The main function of the fixed clamping plate 12 is to fix and support the input pipe 11 in the feeding device to ensure that they will not be displaced or shaken due to vibration, external force impact and other reasons during operation. The feeder 13 can accurately control the amount of raw materials delivered to the reactor according to the production process requirements. It can achieve fine-tuning of the raw material flow by adjusting its own feeding speed, opening and other parameters to ensure that the amount of raw materials entering the reactor meets the optimal ratio and reaction conditions for carbon black production. This is very important for improving the quality of carbon black products and controlling product consistency.

[0038] Reference Figure 1, a belt conveyor 14 is fixedly connected to the upper surface of the bottom plate 1, and a fan connecting plate 15 is fixedly connected to the upper surface of the bottom plate 1. The belt conveyor 14 can realize efficient and continuous transportation of raw materials. It continuously transports the raw materials supplied by the feeder to the next link through the rotation of the belt. It has high transportation efficiency and large transportation capacity, and can meet the demand for large-scale and rapid transportation of raw materials in carbon black production. The main function of the fan connecting plate 15 is to connect the blower 16 with other components in the feeding device, such as the belt conveyor, to form an organic whole. It ensures that the blower 16 can work in conjunction with other equipment, provides a stable connection basis for subsequent operations such as drying and ventilating the raw materials, and ensures the continuity and coordination of the entire feeding device. The preheated raw materials may evaporate more easily due to the increase in temperature, and some of the moisture contained in them may evaporate more easily.

[0039] Reference Figure 1 , a plurality of blowers 16 are provided at both ends of the inner side of the fan connecting plate 15. The airflow blown by the blower 16 can accelerate the evaporation of water, further reduce the moisture content of the raw materials, and effectively prevent the raw materials from agglomerating due to moisture during subsequent transportation, storage or after entering the reactor.

[0040] Reference Figure 1 A fixed box 17 is provided on one side of the belt conveyor 14, and a screw pump B 18 is provided on one side of the fixed box 17. The fixed box 17 can temporarily hold the raw materials after preheating and dehydration, which ensures the integrity and stability of the overall structure and is one of the important components of the overall structure. The function of screw pump B 18 is similar to that of screw pump A. It can further transport the raw materials that have been dried by the hair dryer to the output pipe 19 at a stable flow rate and pressure. Its stable transportation performance ensures that the raw materials can continuously and smoothly enter the reactor, maintains the stability of the chemical reaction in the reactor, and plays an important role in ensuring the quality and production efficiency of carbon black products.

[0041] Reference Figure 1 Screw pump B 18 is equipped with an output pipe 19 at one end, facing the fixed box 17. This pipe serves as the channel for transporting the raw materials delivered by screw pump B 18 to the reactor, ensuring smooth entry of the raw materials for chemical reaction. It is a crucial link between the entire feed device and the reactor, ensuring seamless flow of raw materials from the feed device to the reactor and ensuring the continuity of the carbon black production process.

[0042] The implementation principle of the embodiment of the reactor feeding device for producing high-pigment specialty carbon black in this application is as follows:

[0043] A preheating structure with a rolling shutter has been added to the feed system of the reactor for producing high-pigment specialty carbon black. The operator can control the closing of the shutter by gripping a slider 6 to slide a rolling shutter plate 7 along a slide rod 5. The shutter can be opened and closed flexibly. By adjusting the shutter's opening, the heat dissipation within the preheating structure can be precisely controlled, thereby precisely adjusting the temperature of the raw materials being heated. For example, when the raw materials need to be preheated to a specific temperature range, such as 200-300°C, to meet optimal reaction conditions within the reactor, the shutter's opening can be adjusted based on temperature monitoring to stabilize the raw materials at the desired temperature, ensuring stable carbon black production reactions and consistent product quality. Heat loss is inevitable during the preheating process, but the shutter can significantly reduce this loss. When the raw materials are heated within the preheating structure, closing the shutter creates a relatively enclosed space, effectively preventing heat from dissipating into the surrounding environment, acting as a "thermal barrier" for the preheating area. Compared with open or ordinary closed preheating structures without roller shutters, it can significantly reduce heat loss and improve energy utilization efficiency, thereby reducing the energy consumption cost of carbon black production. The presence of roller shutters helps maintain a relatively stable thermal environment within the preheating structure. When the roller shutters are closed, the flow of hot air inside is relatively smooth and regular, allowing the raw materials to be heated more evenly during the preheating process.
