Description

Technical Field

[0001] The invention relates to the field of fiber raw material processing, and more specifically, to a fiber raw material continuous mixing reaction device and a use method thereof. Background Art

[0002] Fiber raw material continuous mixing reaction equipment is a professional device designed to achieve efficient and continuous mixing and reaction of fiber raw materials. It is usually composed of key parts such as feeding system, mixing zone, reaction zone and discharging system. This equipment greatly improves the efficiency, stability and product quality of fiber raw material mixing reaction, and is widely used in many industries such as chemical fiber, papermaking, textile, etc., promoting the scale and modernization of these industries.

[0003] In the continuous mixing reaction equipment of fiber raw materials, in order to achieve the continuity of the mixing reaction, it is necessary to add heating elements (reasonable heating can make the fiber raw materials better fuse and react with each other, ensure that the product quality meets the requirements, and meet the dual needs of reaction efficiency and quality in continuous production). However, traditional heating devices have many disadvantages, which seriously affect the performance of the equipment. On the one hand, the structural design of traditional heating elements is not reasonable enough, and its installation position often hinders the reasonable layout of the stirring paddle (composed of a stirring rod and a stirring blade), so that the stirring paddle cannot play its full role, and it is difficult to ensure that the material is evenly stirred in the entire mixing tank, thereby affecting the mixing reaction effect. On the other hand, traditional heating devices have obvious defects in temperature control, and their temperature control accuracy is insufficient. It is very easy to have local overheating or overcooling during the heating process. Local overheating will cause the material to heat up rapidly in the high temperature area, exceeding the suitable reaction temperature range; while the overcooling area will cause the material to react slowly or even stagnate, reducing the overall reaction efficiency. More importantly, traditional heating elements are in direct contact with the materials. This contact mode exposes the materials to the high-temperature element surface for a long time, greatly increasing the risk of the raw materials being scorched, deteriorated or having other adverse reactions. This not only affects product quality, but may also cause safety hazards and is not conducive to the stable and efficient operation of the continuous mixing reaction equipment for fiber raw materials.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a fiber raw material continuous mixing reaction device and a method for using the same. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a fiber raw material continuous mixing reaction device and a method for using the same.

An electric motor A for driving a large stirring paddle in the mixing tank to rotate is installed at the top of the mixing tank. The large stirring paddle is divided into a central rotating part and a surrounding part located outside the central rotating part, and there is an annular gap between the two. The top ends of the central rotating part and the surrounding part are connected to the transmission part of the electric motor A through a connecting frame; On the inner bottom wall of the mixing tank, heat-conducting tubes arranged in a circumferential array and located in the annular gap are installed. Electric heating tubes are installed in the heat-conducting tubes to heat the liquid inside them. A liquid injection pipe communicating with the heat-conducting tubes and equipped with a valve is installed at the bottom of the mixing tank.

[0007] Preferably, two sides of the mixing tank are fixedly connected with support plates, and the ends of the support plates are fixedly connected with a base. An outlet pipe is installed at the central part of the bottom end of the heat-conducting tube, and a transmission component for driving a limiting platform to move back and forth is installed at the top end of the base.

[0008] Preferably, the transmission component includes a lead screw driven by an electric motor B installed inside the base. A rod sleeve is threadedly connected to the outer side wall of the lead screw. Guide rails are fixedly connected to both sides inside the base. Both sides of the rod sleeve are slidably connected to the guide rails through sliders, and the limiting platform is installed at the top end of the rod sleeve.

[0009] Preferably, the top end of the mixing tank is detachably connected with a disc by screws. An electric motor C is installed at the central part of the top end of the disc. A connecting piece is fixedly connected to the transmission part of the electric motor C and is connected to a plurality of feeding funnels through the connecting piece. A circular through groove is opened at the part of the disc facing the mixing tank.

[0010] Preferably, a connecting plate is fixedly connected to the outer side wall of the mixing tank, and an electric motor D is installed at the head of the connecting plate. An electric hydraulic rod is installed at the transmission part of the electric motor D, and a small stirring paddle is installed at the transmission part of the electric hydraulic rod.

[0011] Preferably, the top end of the mixing tank is detachably connected with an N-shaped plate A, and a bearing B is installed at the middle part of the N-shaped plate A. A rotating rod is fixedly connected to the inner ring part of the bearing B, and the rotating rod is fixed to the top of the connecting frame. The top end of the N-shaped plate A is fixedly connected with an N-shaped plate B, and the electric motor A is installed on the N-shaped plate B, and its transmission end is connected to the top of the rotating rod.

[0012] Preferably, the other end of the lead screw connected to the electric motor B is rotationally connected to the inside of the base through a bearing A.

[0013] Preferably, the central rotating part is in a cylindrical spiral shape, and the surrounding part is in an annular blade shape.

[0014] Preferably, the support plate is divided into an inner plate and an outer plate, the inner plate slides along the inside of the outer plate, the outer plate is connected to the mixing tank, and the inner plate is connected to the mixing tank, and the two are fixed by screws.

[0015] The method of using the above-mentioned fiber raw material continuous mixing reaction equipment comprises the following steps: Step 1: Add the fiber raw materials that need to be continuously mixed into the mixing tank (the first to be added is the liquid raw materials), set the target heating temperature of the liquid in the heat pipe in the temperature control system according to the appropriate temperature required for the reaction, turn on the motor C, and the motor C drives the connecting piece to make multiple feeding funnels filled with different fiber fixing raw materials start circular motion around the central axis of the disc, and the feeding funnels are aligned with the circular through grooves on the disc in turn, so as to realize the automatic addition of the fiber fixing raw materials; Step 2: Turn on motor A. Motor A drives the large stirring paddle to rotate through the rotating rod and the connecting frame. The central rotating part and the surrounding part of the large stirring paddle work together. The central rotating part uses the cylindrical spiral structure to generate axial propulsion, driving the material in the central area of ​​the mixing tank to circulate up and down, breaking the static state of the material. The surrounding part relies on the annular paddle design to strongly shear and stir the material near the tank wall, and draw the material near the tank wall into the stirring system, and cooperate with the central rotating part to form a complex convection mixing of the material, stirring the material in all directions. Step 3: Start the electric heating tube to heat the liquid in the heat pipe. Due to the good fluidity of the liquid, the heat is quickly and evenly diffused during heating, and the heat is stably transferred to the material in the mixing tank through the wall of the heat pipe to achieve indirect heating. The temperature control system monitors and accurately controls the liquid temperature in real time, effectively reducing local overheating or overcooling, allowing the material to fully react at an appropriate temperature, meeting the requirements of continuous production for reaction efficiency and quality; Step 4: When the mixing reaction is completed, the operator places the container for collecting materials on the limit table. The limit table can prevent the container from shifting during the collection process. Start motor B and control it to rotate forward. Motor B drives the screw to rotate, and the screw drives the rod sleeve to move directly below the discharge pipe. When the rod sleeve moves, it drives the slider to slide in the guide rail to ensure that the rod sleeve moves in a straight line, thereby driving the limit table to move accurately to the bottom of the discharge pipe. At this time, open the valve of the discharge pipe, and the reacted material in the mixing tank flows into the container below through the discharge pipe. After collection is completed, start motor B and control it to reverse, so that the limit table moves out from directly below the discharge pipe, making it convenient for the staff to take away the container containing the material.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cleverly avoids the heat-conducting tubes arranged in a circumferential array on the inner bottom wall of the mixing tank, creating conditions for the reasonable layout of the large stirring paddle in the mixing tank. Moreover, the heated liquid circulates in the heat-conducting tubes, and the heat is evenly and stably transferred to the materials in the mixing tank through the tube walls of the heat-conducting tubes, realizing the indirect heating of the materials. This indirect heating method completely changes the disadvantages of the direct contact between the traditional heating element and the materials. The materials will not be exposed to the surface of the high-temperature element for a long time, greatly reducing the risk of the raw materials being scorched, deteriorated or having other adverse reactions. At the same time, compared with the traditional heating device, this equipment has significant advantages in temperature control. By precisely regulating the temperature of the liquid in the heat-conducting tubes, local overheating or overcooling phenomena can be effectively reduced, enabling the materials to be evenly heated at an appropriate temperature all the time, promoting the better mutual fusion and reaction of the fiber raw materials, and thus meeting the double strict requirements for reaction efficiency and quality in continuous production, so as to solve the problems that the structural design of the traditional heating element in the background technology is not reasonable enough, its installation position often hinders the stirring paddle, and the direct heating method of the traditional heating element has defects; 2. The central rotating part of the present invention is in a cylindrical spiral shape, and the surrounding part is in a ring-shaped blade shape. The central rotating part being in a cylindrical spiral shape can generate an axial propulsive force during rotation, prompting the materials to move axially along the spiral trajectory of the central rotating part. Just like a screw conveyor, it can effectively drive the materials in the central area of the mixing tank to circulate up and down, breaking the static state of the materials in the central position and enhancing the fluidity of the materials. And the surrounding part is in a ring-shaped blade shape, and its large ring-shaped blade area can generate a strong shearing and stirring effect on the materials near the tank wall in the mixing tank during rotation, significantly improving the working performance of the continuous mixing reaction equipment for fiber raw materials; 3. The operator of the present invention first places the container for collecting materials on the limiting platform. The limiting platform plays a role in limiting the container to prevent it from shifting during the collection process. When it is necessary to collect materials, start motor B and control the forward rotation of motor B to accurately move the container on the limiting platform to directly below the discharge pipe. Open the valve of the discharge pipe, and the reacted materials in the mixing tank will flow into the lower container through the discharge pipe. After the collection is completed, start motor B and control the reverse rotation of motor B, so as to move the limiting platform out from directly below the discharge pipe, facilitating the staff to take it away, so as to achieve convenient and efficient material collection; 4. The present invention realizes an intermittent and automated fiber raw material addition process through an efficient automatic addition device, greatly saving manpower.

Detailed implementation manners

[0019] Embodiment 1 As Figures 1 to 5 As shown in FIGS. 33 and 8, the present invention provides a continuous mixing reaction device for fiber raw materials, including a mixing tank 1. An electric motor A2 for driving the large stirring paddle 3 in the mixing tank 1 to rotate is installed at the top of the mixing tank 1. The large stirring paddle 3 is divided into a central rotating part 301 and a surrounding part 302 located outside the central rotating part 301. There is an annular gap between the two. The top ends of the central rotating part 301 and the surrounding part 302 are connected to the transmission part of the electric motor A2 through a connecting frame 4; Heat conduction tubes 5 arranged in a circumferential array and located in the annular gap are installed on the inner bottom wall of the mixing tank 1. Electric heating tubes 6 are installed in the heat conduction tubes 5 to heat the liquid inside them. A liquid injection tube 7 communicating with the heat conduction tubes 5 and equipped with a valve is installed at the bottom of the mixing tank 1.

[0020] During operation, motor A1 is turned on, and motor A2 drives the large stirring paddle 3 to rotate through the connecting frame 4. The large stirring paddle 3 is uniquely divided into a central rotating part 301 and a surrounding part 302. The annular gap design between the two cleverly avoids the heat conduction tubes 5 arranged in a circumferential array on the inner bottom wall of the mixing tank 1, creating conditions for the reasonable layout of the large stirring paddle 3 in the mixing tank 1. During the rotation of the large stirring paddle 3, the central rotating part 301 and the surrounding part 302 can work together to stir the material in all directions from the central area to the peripheral area, ensuring that the material tumbles evenly and is fully mixed throughout the mixing tank 1.

[0021] In the heating process, the operator injects liquid into the heat conduction tubes 5 through the liquid injection pipe 7, and then the electric heating tube 6 starts to work to heat the liquid in the heat conduction tubes 5 (made of heat-conducting material). The heated liquid circulates in the heat conduction tubes 5, and the heat is evenly and stably transferred to the material in the mixing tank 1 through the tube walls of the heat conduction tubes 5, achieving indirect heating of the material. This indirect heating method completely changes the disadvantages of the traditional heating element directly contacting the material. The material will not be exposed to the surface of the high-temperature element for a long time, greatly reducing the risk of the raw material being burned, deteriorated, or having other adverse reactions. At the same time, compared with the traditional heating device, this equipment has significant advantages in temperature control. By precisely regulating the temperature of the liquid in the heat conduction tubes 5 (the liquid has good fluidity. When the electric heating tube heats it, the heat can quickly and evenly diffuse in the liquid. As a heat transfer medium, the liquid has a large heat capacity and can buffer the temperature change to a certain extent, making the temperature control more stable and accurate, and more conducive to precise temperature regulation), local overheating or overcooling phenomena can be effectively reduced, and the material is always evenly heated at an appropriate temperature (the liquid has a large heat capacity and good fluidity. When the heating element heats the liquid, the liquid can absorb a large amount of heat with a high specific heat capacity and the temperature rises gently, avoiding the local high temperature caused by heat concentration near the heating element during direct heating; at the same time, the liquid forms a dynamic flow under the action of natural convection, promoting the rapid diffusion of heat in the liquid and eliminating the internal temperature gradient to achieve a uniform distribution of its own temperature), promoting better mutual fusion and reaction of the fiber raw materials, and then meeting the double strict requirements of reaction efficiency and quality in continuous production, and effectively ensuring the stable and efficient operation of the equipment. (The liquid can be water, heat-conducting oil, etc.) Furthermore, the central rotating part 301 is in the shape of a cylindrical helix, and the surrounding part 302 is in the shape of an annular blade. The central rotating part 301 being in the shape of a cylindrical helix can generate an axial propulsive force during rotation, causing the material to move axially along the helical trajectory of the central rotating part 301. Just like a screw conveyor, it can effectively drive the material in the central area of the mixing tank 1 to circulate up and down, breaking the static state of the material at the central position and enhancing the fluidity of the material. The surrounding part 302 being in the shape of an annular blade can generate a strong shearing and stirring effect on the material near the tank wall in the mixing tank 1 during rotation. On the one hand, the annular blade can quickly draw the relatively static or slowly flowing material near the tank wall into the stirring system, preventing the material from accumulating at the tank wall. On the other hand, when working in cooperation with the central rotating part 301, the annular blade-shaped surrounding part 302 can further disperse the material driven by the central rotating part 301 to the surroundings, enabling the material to form a more complex and thorough convective mixing in the entire mixing tank 1, greatly improving the stirring efficiency, ensuring that the fiber raw materials can be evenly mixed in the mixing tank 1, providing a good material basis for subsequent reactions, and significantly enhancing the working performance of the continuous mixing reaction equipment for fiber raw materials.

[0022] Moreover, an N-shaped plate A22 is detachably connected to the top of the mixing tank 1, and a bearing B23 is installed at the middle part of the N-shaped plate A22. A rotating rod 24 is fixedly connected to the inner ring part of the bearing B23. The rotating rod 24 is fixed to the top of the connecting frame 4. The top of the N-shaped plate A22 is fixedly connected to an N-shaped plate B25. The motor A2 is installed on the N-shaped plate B25, and its transmission end is connected to the top of the rotating rod 24.

[0023] The top of the mixing tank 1 is connected to the N-shaped plate A22 in a detachable manner. This design first provides great convenience for the maintenance and repair of the equipment. When it is necessary to inspect, repair, or replace the large stirring paddle 3 inside the mixing tank 1, the large stirring paddle 3 can be removed by disassembling the N-shaped plate A22, shortening the maintenance time and improving the operating efficiency of the equipment. The bearing B23 can provide a stable and low-friction rotating support for the rotating rod 24. When the motor A2 drives the rotating rod 24 to rotate, the bearing B23 can effectively reduce the energy loss during rotation, ensuring that the rotating rod 24 can operate smoothly and efficiently, and then driving the stable rotation of the connecting frame 4 and the large stirring paddle 3 connected thereto.

[0024] Embodiment 2 As Figures 1 - 4As shown in FIGS. 5 and 6, in order to facilitate the collection of the materials after the continuous mixing reaction in the mixing tank 1 through a container, the present invention fixedly connects support plates 13 on both sides of the mixing tank 1, and a base 8 is fixedly connected to the end of the support plate 13. A discharge pipe 9 is installed at the central part of the bottom end of the heat conduction pipe 5. A transmission assembly 10 for driving and limiting the platform 11 to move back and forth is arranged on the top end of the base 8. The transmission assembly 10 includes a lead screw 1002 driven by a motor B1001 installed inside the base 8. A rod sleeve 1003 is threadedly connected to the outer side wall of the lead screw 1002. Guide rails 1004 are fixedly connected to both sides inside the base 8. Both sides of the rod sleeve 1003 are slidably connected to the guide rails 1004 through sliders 1005. The limiting platform 11 is installed at the top end of the rod sleeve 1003.

[0025] During use, the operator first places the container for collecting materials on the limiting platform 11. The limiting platform 11 plays a role in limiting the container to prevent it from shifting during the collection process. When it is necessary to collect materials, start the motor B and control the forward rotation of the motor B1001. The motor drives the rotation of the lead screw 1002, and the lead screw 1002 drives the rod sleeve 1003 to move directly below the discharge pipe 9. The rod sleeve 1003 drives the movement of the slider 1005, and the slider 1005 slides along the guide rail 1004 to maintain the linear movement of the rod sleeve 1003, thereby driving the linear movement of the limiting platform 11, accurately moving the container on the limiting platform 11 directly below the discharge pipe 9. Open the valve of the discharge pipe 9, and the materials after the reaction in the mixing tank 1 will flow into the lower container through the discharge pipe 9. After the collection is completed, start the motor B1001 and control the reverse rotation of the motor B1001, so as to move the limiting platform 11 out from directly below the discharge pipe 9, facilitating the staff to take it away, so as to realize convenient and efficient material collection.

[0026] Furthermore, the other end of the lead screw 1002 connected to the motor B1001 is rotatably connected to the inside of the base 8 through a bearing A1006. The bearing A1006 can provide stable and reliable support for the lead screw 1002, ensuring that when the lead screw 1002 rotates at a high speed driven by the motor B1001, it always maintains an accurate axis position, avoiding shaking or deviation, thereby ensuring the stability of the operation of the entire transmission assembly 10. And the support plate 13 is divided into an inner plate and an outer plate. The inner plate slides along the inside of the outer plate. The outer plate is connected to the mixing tank 1, and the inner plate is connected to the mixing tank 1. The two are fixed by screws. The sliding connection structure of the inner plate and the outer plate provides great flexibility for the installation of the equipment. During the actual installation process, according to the specific space layout on site and the equipment placement requirements, the overall length of the support plate 13 can be flexibly adjusted by sliding the inner plate to ensure that the mixing tank 1 can be stably installed in different working environments, improving the adaptability of the equipment to diverse installation scenarios.

[0027] Embodiment 3 At present, during the processing of fiber raw materials by continuous mixing and reaction equipment for fiber raw materials, different fiber fixed raw materials need to be added intermittently, generally by manual addition, which is very labor-consuming. Therefore, as Figures 1 - 4 As shown in FIGS. 6 and 7, a disc 12 is detachably connected to the top of the mixing tank 1 by screws. A motor C14 is installed at the center of the top of the disc 12. A connecting member 15 is fixedly connected to the transmission part of the motor C14. The connecting member 15 is connected to a plurality of feeding funnels 16. A circular through groove 17 is formed at the part of the disc 12 facing the mixing tank 1. The bottom of the feeding funnel 16 is initially in close contact with the disc 12, so as to confine the raw materials in the feeding funnel 16. The raw materials can be discharged only when the feeding funnel 16 is aligned with the circular through groove 17.

[0028] The present invention designs an efficient automatic adding device. The disc 12 is connected to the top of the mixing tank 1 by screws, ensuring the convenience of equipment maintenance and component replacement. The motor C14 is installed at the center of the top of the disc 12, and its transmission part is firmly connected to a plurality of feeding funnels 16 through the connecting member 15. After the motor C14 is started, it drives the connecting member 15 to rotate by its own rotational power, and then makes a plurality of feeding funnels 16 move in a circular motion around the central axis of the disc 12. A circular through groove 17 is formed on one side of the disc 12 facing the mixing tank 1. In the initial state, the bottom of the feeding funnel 16 is in close contact with the disc 12. By using this sealed contact, various fiber raw materials are respectively confined in the corresponding feeding funnels 16 to avoid accidental leakage of raw materials. As the motor C14 continuously drives the feeding funnel 16 to rotate, when a certain feeding funnel 16 rotates to coincide with the position of the circular through groove 17, a material channel is formed between the two. At this time, the fiber raw materials in the feeding funnel 16 will fall into the mixing tank 1 below under the action of gravity along the circular through groove 17, accurately completing an automatic adding operation of fiber raw materials. By cycling in this way, an intermittent and automated fiber raw material adding process is realized, greatly saving labor.

[0029] Furthermore, a connecting plate 18 is fixedly connected to the outer side wall of the mixing tank 1, and a motor D19 is installed at the head of the connecting plate 18. An electric hydraulic rod 20 is installed at the transmission part of the motor D19, and a small stirring paddle 21 is installed at the transmission part of the electric hydraulic rod 20.

[0030] That is, when a blockage occurs during the process of adding fixed raw materials from the feeding funnel 16 to the mixing tank 1, the electric hydraulic rod 20 can drive the large stirring paddle 3 to move downward and extend it into the feeding funnel 16 (and then reset after stirring). Then, the motor D19 drives the electric hydraulic rod 20 to rotate, thereby driving the small stirring paddle 21 to rotate to stir the solid raw materials in the feeding funnel 16 to achieve the role of dredging.

[0031] The present invention also provides a method for using the above-mentioned continuous mixing and reaction equipment for fiber raw materials: Step 1: Add the fiber raw materials that need to be continuously mixed and reacted into the mixing tank 1 (the liquid raw materials are added first). According to the appropriate temperature required for the reaction, set the target heating temperature of the liquid in the heat conduction pipe 5 in the temperature control system. Turn on the motor C14. The operation of the motor C14 drives the connecting piece 15, and then makes multiple feeding funnels 16 filled with different fiber fixed raw materials start to move in a circular motion around the central axis of the disc 12. The feeding funnels 16 are sequentially aligned with the circular through grooves 17 on the disc 12 to achieve automatic addition of the fiber fixed raw materials; Step 2: Turn on the motor A2. The motor A2 drives the large stirring paddle 3 to rotate through the rotating rod 24 and the connecting frame 4. The central rotating part 301 and the surrounding part 302 of the large stirring paddle 3 cooperate. The central rotating part 301 uses the cylindrical spiral structure to generate an axial propulsive force, driving the materials in the central area of the mixing tank 1 to circulate up and down, breaking the static state of the materials. The surrounding part 302, relying on the annular blade design, strongly shears and stirs the materials near the tank wall, rolls the materials near the tank wall into the stirring system, and cooperates with the central rotating part 301 to make the materials form a complex convective mixing, stirring the materials in all directions; Step 3: Start the electric heating tube 6 to heat the liquid in the heat conduction pipe 5. Due to the good fluidity of the liquid, the heat spreads quickly and evenly during heating. The heat is stably transferred to the materials in the mixing tank 1 through the wall of the heat conduction pipe 5 to achieve indirect heating. The temperature control system monitors and accurately controls the liquid temperature in real time, effectively reducing the phenomenon of local overheating or overcooling, enabling the materials to fully react at an appropriate temperature, and meeting the requirements of continuous production for reaction efficiency and quality; Step 4: When the mixing reaction is completed, the operator places the container for collecting the materials on the limiting platform 11. The limiting platform 11 can prevent the container from shifting during the collection process. Turn on the motor B1001 and control it to rotate forward. The motor B1001 drives the lead screw 1002 to rotate. The lead screw 1002 drives the rod sleeve 1003 to move directly below the discharge pipe 9. When the rod sleeve 1003 moves, it drives the slider 1005 to slide in the guide rail 1004 to ensure the linear movement of the rod sleeve 1003, and then drives the limiting platform 11 to accurately move below the discharge pipe 9. At this time, open the valve of the discharge pipe 9, and the reacted materials in the mixing tank 1 flow into the lower container through the discharge pipe 9. After the collection is completed, turn on the motor B1001 and control it to rotate in reverse to move the limiting platform 11 out from directly below the discharge pipe 9, facilitating the staff to take away the container filled with the materials.

[0032] A continuous mixing and reaction equipment for fiber raw materials and its using method according to the present invention have the following advantages: It cleverly avoids the heat-conducting tubes 5 arranged in a circumferential array on the inner bottom wall of the mixing tank 1, creating conditions for the reasonable layout of the large stirring paddle 3 in the mixing tank 1. Moreover, the heated liquid circulates in the heat-conducting tubes 5, and the heat is evenly and stably transferred to the materials in the mixing tank 1 through the tube walls of the heat-conducting tubes 5, realizing the indirect heating of the materials. This indirect heating method completely changes the disadvantages of the traditional heating element directly contacting the materials. The materials will not be exposed to the surface of the high-temperature element for a long time, greatly reducing the risk of the raw materials being scorched, deteriorated or having other adverse reactions. At the same time, compared with the traditional heating device, this equipment has significant advantages in temperature control. By precisely regulating the temperature of the liquid in the heat-conducting tubes 5, the phenomenon of local overheating or overcooling can be effectively reduced, enabling the materials to be uniformly heated at an appropriate temperature all the time, promoting the better mutual fusion and reaction of the fiber raw materials, and then meeting the dual strict requirements for reaction efficiency and quality in continuous production; The central rotating part 301 is in a cylindrical spiral shape, and the surrounding part 302 is in a ring-shaped blade shape. The central rotating part 301 being in a cylindrical spiral shape can generate an axial propulsive force during rotation, prompting the materials to move axially along the spiral trajectory of the central rotating part 301. Just like a screw conveyor, it can effectively drive the materials in the central area of the mixing tank 1 to circulate up and down, breaking the static state of the materials in the central position and enhancing the fluidity of the materials. The surrounding part 302 is in a ring-shaped blade shape, and its large ring-shaped blade area can generate a strong shearing and stirring effect on the materials near the tank wall in the mixing tank 1 during rotation, significantly improving the working performance of the continuous mixing reaction equipment for fiber raw materials; The operator first places the container for collecting materials on the limiting platform 11. The limiting platform 11 plays a role in limiting the container to prevent it from shifting during the collection process.

10. A method for using the fiber raw material continuous mixing reaction equipment according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Add the fiber raw materials to be continuously mixed into the mixing tank (1), set the target heating temperature of the liquid in the heat conducting tube (5) in the temperature control system according to the appropriate temperature required for the reaction, turn on the motor C (14), and the motor C (14) drives the connecting piece (15) to make a plurality of feeding funnels (16) filled with different fiber fixing raw materials start circular motion around the central axis of the disc (12), and the feeding funnels (16) are aligned with the circular through grooves (17) on the disc (12) in turn, so as to realize the automatic addition of the fiber fixing raw materials; Step 2: Turn on the motor A (2). The motor A (2) drives the large stirring paddle (3) to rotate via the rotating rod (24) and the connecting frame (4). The central rotating portion (301) and the surrounding portion (302) of the large stirring paddle (3) work in coordination. The central rotating portion (301) generates an axial propulsion force using a cylindrical spiral structure to drive the material in the central area of ​​the mixing tank (1) to circulate upward and downward, thereby breaking the static state of the material. The surrounding portion (302) uses a ring-shaped paddle design to strongly shear and stir the material near the tank wall, thereby drawing the material near the tank wall into the stirring system, and cooperates with the central rotating portion (301) to form a complex convection mixing of the material, thereby stirring the material in all directions. Step 3: Start the electric heating tube (6) to heat the liquid in the heat conducting tube (5). Due to the good fluidity of the liquid, the heat is quickly and evenly diffused during heating, and the heat is stably transferred to the material in the mixing tank (1) through the wall of the heat conducting tube (5), thereby achieving indirect heating. The temperature control system monitors and accurately controls the temperature of the liquid in real time, effectively reducing local overheating or overcooling, allowing the material to fully react at an appropriate temperature, thereby meeting the requirements of continuous production for reaction efficiency and quality. Step 4: After the mixing reaction is completed, the operator places the container for collecting the materials on the limit table (11). The limit table (11) can prevent the container from shifting during the collection process. The motor B (1001) is started and controlled to rotate forward. The motor B (1001) drives the screw rod (1002) to rotate. The screw rod (1002) drives the rod sleeve (1003) to move directly below the discharge pipe (9). When the rod sleeve (1003) moves, it drives the slider (1005). The rod sleeve (1003) slides in the guide rail (1004) to ensure that the rod sleeve (1003) moves in a straight line, thereby driving the limit platform (11) to move accurately to the bottom of the discharge pipe (9). At this time, the valve of the discharge pipe (9) is opened, and the reacted materials in the mixing tank (1) flow into the container below through the discharge pipe (9). After the materials are collected, the motor B (1001) is started and controlled to reverse, so that the limit platform (11) moves out from the bottom of the discharge pipe (9), and the staff takes away the container containing the materials.
