Description

Technical Field

[0001] This invention belongs to the field of polyamide 66 production technology, specifically a catalytic device for polyamide fiber raw materials and its catalytic method. Background Technology

[0002] The polyamide fiber raw material catalytic device is the core equipment in the polyamide production process. It is responsible for catalyzing the polymerization reaction of raw materials under high temperature and high pressure conditions, and finally generating polymers that can be used to manufacture polyamide fibers.

[0003] Existing polyamide fiber raw material catalytic devices produce polyamide 66 (PA66) through catalytic polymerization. By precisely controlling reaction conditions, raw materials such as adipic acid and hexamethylenediamine are catalytically polymerized into polyamide 66 chains. However, in actual catalytic reaction processes, the catalyst is usually placed statically in the reaction tank. On the one hand, the catalyst is stacked and folded, reducing the contact area with the reactants and thus slowing down the reaction rate. On the other hand, due to the large diameter range of the reaction tank, the total amount of statically placed catalyst is limited, and its position in the reaction tank is relatively fixed and limited. During the current rotating stirring process, some materials inside the reaction tank still cannot make good contact with the catalyst. Furthermore, the stirring direction and method during material mixing in the current reaction tank are all the same, which cannot achieve a more effective stirring effect. As a result, the actual reaction rate is low and the production efficiency is low. Summary of the Invention

[0004] The purpose of this invention is to provide a catalytic device and catalytic method for polyamide fiber raw materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polyamide fiber raw material catalytic device and its catalytic method, comprising a reaction chamber, a rotating shaft rotatably mounted inside the reaction chamber, a stirring plate fixedly connected to the outer surface of the rotating shaft, a triangular cam fixedly sleeved on the outer surface of the rotating shaft, a storage component movably sleeved on the inner wall of the reaction chamber, an arc-shaped guide plate fixedly connected to the inner end of the storage component, a sealing component provided on the outer side of the reaction chamber, the sealing component sleeved on the outer side of the storage component, a pushing component provided inside the storage component, and catalyst particles filled inside the storage component. During rotation, the triangular cam pushes the arc-shaped guide plate. The storage component includes a storage cylinder and a through hole. One end of the storage cylinder is fixedly connected to an arc-shaped guide plate, and the other end moves through the reaction chamber.

[0006] Preferably, the feeding assembly includes a pull rod, a first movable plate, a second movable plate, and a sealing baffle. The first movable plate is fixedly connected to the movable end of the pull rod, the second movable plate is fixedly sleeved on the outer surface of the pull rod, and the sealing baffle is fixedly connected to the other end of the pull rod. The first movable plate, the second movable plate, and the sealing baffle are all movably sleeved inside the storage cylinder.

[0007] Preferably, an impact column is fixedly connected to the inner side of the arc-shaped guide plate, and the impact column is symmetrically fixed on both sides of the storage cylinder.

[0008] Preferably, auxiliary processing components are fixedly connected to both the upper and lower sides of the outer surface of the storage cylinder. The auxiliary processing components include a connecting rod and an arc-shaped plate. The connecting rod is fixedly connected to the outer surface of the storage cylinder, and the arc-shaped plate is fixedly connected to the connecting rod. The arc-shaped plate is located on the rotation path of the gap between the two sets of stirring plates, and the arc-shaped plate and the arc-shaped guide plate have opposite arc directions.

[0009] Preferably, the sealing assembly includes an outer cylinder, a spring, and a mounting ring. The mounting ring is fixed to the outer side of the reaction chamber and sleeved on the outside of the storage cylinder. One end of the spring is fixedly connected to the outer cylinder, and the other end is fixedly connected to the storage cylinder.

[0010] Preferably, a power motor is fixedly installed on the top of the reaction chamber, the output shaft of the power motor is fixedly connected to the rotating shaft, and a sealing sleeve is fitted on the outer side of the rotating shaft, which is sealed and fixedly connected to the inner wall of the reaction chamber.

[0011] Preferably, the outer surface of the rotating shaft is provided with an intake port, the interior of the rotating shaft is provided with an installation cavity, and a fan is provided inside the installation cavity. The fan flushes air through the intake port and inputs it into the interior of the installation cavity.

[0012] Preferably, the outer side of the triangular cam is provided with a blow hole, the blow hole is connected to the mounting cavity, and the blow hole corresponds one-to-one with the three apex corners of the triangular cam.

[0013] A catalytic method for a polyamide fiber raw material catalytic device includes the following catalytic method: Step 1: Open the feed port at the top of the reaction chamber, put the material to be reacted into the reaction chamber, seal the feed port, loosen the outer cylinder in the sealing assembly, pull the outer cylinder outward, drive the storage cylinder to move outward by the spring, and use the opened mounting ring to pull out part of the pusher assembly along the inside of the storage cylinder. Then put the catalyst particles into the storage cylinder, push the pusher assembly and reset it to store the catalyst particles in the storage assembly, and then fix the sealing assembly again. Step 2: Pressurize and heat the inside of the reaction chamber to increase the internal pressure and temperature. The reactants begin to react under the action of high temperature and catalyst, and water is produced. The water evaporates into water vapor at high temperature. As the water vapor continues to fill the reaction chamber, the exhaust valve is opened under high pressure to release the internal water vapor. Step 3: Start the power motor and drive the rotating shaft to rotate, so that the rotating shaft drives the stirring plate and the triangular cam to rotate synchronously. As the stirring plate rotates, the triangular cam rotates and pushes the outer arc-shaped guide plate during the rotation. With the pushing action, the storage component moves laterally and compresses the spring. At the same time, the pushing component in the storage component squeezes the spring. As the triangular cam and the arc-shaped guide plate are misaligned, the spring causes the storage component to elastically reset. The catalyst particles in the storage component vibrate rapidly, completing the automatic vibration and disturbance. Step 4: When the arc-shaped guide plate moves elastically back and forth, it drives the impact column to move, causing the impact column to collide with the inner wall of the reaction chamber, causing the inside of the reaction chamber to vibrate and detach the material from the inner wall. Step 5: As the storage component moves laterally, it drives the auxiliary processing component to move synchronously. As the auxiliary processing component moves, the arc-shaped plate pushes the mixture to flow in the reaction chamber, completing further disturbance. Step 6: When it is necessary to enhance the removal of byproducts from the system during the catalytic process, start the fan in the rotating shaft to draw air from the reaction chamber and transport it to the mounting cavity. The air is then blown through the purge hole to the edge of the triangular cam, enhancing the air disturbance between the triangular cam and the arc-shaped guide plate to complete the dispersion and reaction.

[0014] The beneficial effects of this invention are as follows: (1) This invention utilizes a rotating shaft to drive the rotation of a triangular cam. The rotation effect of the triangular cam, in conjunction with the arc-shaped guide plates distributed inside the reaction chamber, causes the storage component to reciprocate and sway by squeezing the arc-shaped guide plates, thereby causing the internal catalyst particles to vibrate back and forth. During the vibration process, the accumulated catalyst particles are fully mixed and disturbed, avoiding the accumulation of catalyst particles. Through vibration disturbance, the contact area with the mixed materials is increased, thereby improving the catalytic effect of the catalytic reaction. At the same time, during the vibration process, as the arc-shaped guide plates drive the storage component to change position inside the reaction chamber, it adapts to the position of the materials inside the reaction chamber. In conjunction with stirring and rotating the materials, the materials in all parts of the reaction chamber are fully catalyzed, further improving the contact effect and comprehensively improving the catalytic reaction efficiency. The effect is good.

[0015] (2) By utilizing the sealing component, the pushing component and the storage component, the present invention enables the reciprocating movement of the storage component while cooperating with the elastically connected outer cylinder. When the outer cylinder is unscrewed and pulled open, the sealing of the pushing component can be released. By pulling the pushing component, the internally stored catalyst can be removed and the catalyst particles can be replaced. For catalysts that have lost or reduced activity, quick replacement and maintenance can be achieved, reducing the difficulty of replacement operation and resulting in good practical use effect.

[0016] (3) By utilizing the combination of the arc-shaped guide plate and the triangular cam, the impact column and the auxiliary processing component are driven to move simultaneously during the rotation. On the one hand, the impact column expands with the inner wall of the reaction chamber, and the vibration effect generated by the expansion automatically removes the material adhering to the inner wall, avoiding some material splashing and adhering to the inner wall during violent reaction. On the other hand, by utilizing the arrangement of the arc-shaped plate in the auxiliary processing component, in conjunction with the arc-shaped plate and the arc-shaped guide plate with opposite arc orientations, the arc-shaped plate and the arc-shaped guide plate are squeezed and disturbed in the mixture during the squeezing and pushing. In conjunction with the rotating stirring plate, more directional disturbance treatment is provided to the reactants during the actual reaction process, thereby further improving the uniformity of the mixture and the reaction efficiency. The actual catalytic reaction effect of the catalytic device is better.

[0017] (4) The present invention utilizes a fan in the rotating shaft to draw in excess water vapor in the reaction chamber when needed and re-inject it into the mixture. In conjunction with the rotating triangular cam, the mixture is sprayed towards the area of ​​the arc-shaped guide plate during the rotation and spraying process. On the one hand, the water vapor blown out disturbs the steam flow, thereby further improving the mixing effect of the mixture. On the other hand, the generated by-product water vapor is reintroduced into the mixture for secondary treatment, avoiding the water vapor from carrying away some unreacted materials, improving the purity of by-products, avoiding the loss of reactants, and improving the quality of the final catalytic reaction.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 9 As shown, this embodiment of the invention provides a catalytic device and catalytic method for polyamide fiber raw materials, including a reaction chamber 1. A rotating shaft 3 is rotatably mounted inside the reaction chamber 1. A stirring plate 5 is fixedly connected to the outer surface of the rotating shaft 3. A triangular cam 4 is fixedly sleeved on the outer surface of the rotating shaft 3. A storage component 6 is movably sleeved on the inner wall of the reaction chamber 1. An arc-shaped guide plate 11 is fixedly connected to the inner end of the storage component 6. A sealing component 7 is provided on the outer side of the reaction chamber 1. The sealing component 7 is sleeved on the outer side of the storage component 6. A pushing component 8 is provided inside the storage component 6. The storage component 6 is filled with catalyst particles. During the rotation of the triangular cam 4, the arc-shaped guide plate 11 is pushed. The storage component 6 includes a storage cylinder 61 and a through hole 62. One end of the storage cylinder 61 is fixedly connected to the arc-shaped guide plate 11, and the other end moves through the reaction chamber 1.

[0022] Example 1: Open the feed inlet at the top of the reaction chamber 1, and put the material to be reacted into the reaction chamber 1. Seal the feed inlet. Pull the outer cylinder 71 of the sealing assembly 7 outward from the mounting ring 73. Drive the storage cylinder 61 to move outward through the spring 72. Utilize the gap between the opened mounting ring 73 and the stretched spring 72 to pull out part of the pusher assembly 8 along the inside of the storage cylinder 61. When the movable plate 83 is pulled out of the storage cylinder 61, the catalyst particles are then put into the storage cylinder 61. Push the movable plate 83 in the pusher assembly 8 and reset it, storing the catalyst particles in the storage assembly 6. Then, re-fix the sealing assembly 7. Pressurize and heat the inside of the reaction chamber 1 to increase the internal pressure and temperature. The reactants begin to react under high temperature and the action of the catalyst, producing water as a byproduct. The water evaporates into steam at high temperature. As the steam continues to fill the reaction chamber 1, the exhaust valve 10 is opened under high pressure, releasing the contents of the chamber. Steam is generated in the first part of the container; the power motor 2 is started, and the rotating shaft 3 is driven to rotate, so that the rotating shaft 3 drives the stirring plate 5 and the triangular cam 4 to rotate synchronously. As the stirring plate 5 rotates, the triangular cam 4 rotates, and intermittently pushes the outer arc-shaped guide plate 11 during the rotation. With the pushing action, the storage component 6 moves laterally and compresses the spring 72. At the same time, the pushing component 8 in the storage component 6 squeezes the spring 72. As the triangular cam 4 and the arc-shaped guide plate 11 are misaligned, the spring 72 drives the storage component 6 to elastically reset. The catalyst particles in the storage component 6 vibrate rapidly, completing automatic vibration and mixing. When the arc-shaped guide plate 11 moves elastically back and forth, it drives the impact column 12 to move, so that the impact column 12 collides with the inner wall of the reaction box 1. The inside of the reaction box 1 vibrates and the material on the inner wall is detached. As the storage component 6 moves laterally, it drives the auxiliary processing component 9 to move synchronously. As the auxiliary processing component 9 moves, the arc-shaped plate 92 pushes the mixture to flow in the reaction box 1, completing further disturbance.

[0023] First, the rotating shaft 3 drives the triangular cam 4 to rotate. The rotation of the triangular cam 4, in conjunction with the arc-shaped guide plates 11 distributed inside the reaction chamber 1, causes the storage component 6 to reciprocate and sway, thereby causing the internal catalyst particles to vibrate. During this vibration, the accumulated catalyst particles are fully mixed and disturbed, preventing particle accumulation. The vibration increases the contact area with the mixed materials, thus improving the catalytic effect. Simultaneously, as the arc-shaped guide plates 11 move the storage component 6 within the reaction chamber 1, adapting to the material position and agitating the rotating materials, the materials in all parts of the reaction chamber 1 are thoroughly catalyzed, further improving the contact effect and overall enhancing the catalytic reaction efficiency, resulting in good performance.

[0024] Furthermore, by utilizing the sealing component 7, the pushing component 8, and the storage component 6, while the storage component 6 is reciprocating and being pushed, the outer cylinder 71, which is elastically connected, allows the sealing of the pushing component 8 to be released when the outer cylinder 71 is unscrewed and pulled open. By pulling the pushing component 8, the internally stored catalyst can be removed, and the catalyst particles can be replaced. For catalysts that have lost or reduced activity, quick replacement and maintenance can be achieved, reducing the difficulty of replacement operations and resulting in good practical performance.

[0025] On the other hand, by utilizing the cooperation between the arc-shaped guide plate 11 and the triangular cam 4, the impact column 12 and the auxiliary processing component 9 are driven to move simultaneously during rotation. On the one hand, the impact column 12 expands against the inner wall of the reaction chamber 1, and the vibration effect generated by the expansion automatically removes the material adhering to the inner wall, avoiding some material splashing and adhering to the inner wall during violent reaction. On the other hand, by utilizing the arrangement of the arc-shaped plate 92 in the auxiliary processing component 9, in conjunction with the arc-shaped plate 92 and the arc-shaped guide plate 11 with opposite arc orientations, the arc-shaped plate 92 and the arc-shaped guide plate 11 are squeezed and pushed to achieve the squeezing and disturbance of the mixture. Combined with the rotating stirring plate, more directional disturbance treatment is provided to the reactants during the actual reaction process, thereby further improving the uniformity of the mixture, improving the reaction efficiency, and the catalytic reaction effect of the actual catalytic device is better.

[0026] Example 2: When it is necessary to enhance the catalytic process, start the blower 16 in the rotating shaft 3 to draw air from the reaction chamber 1 and draw it into the interior of the rotating shaft 3 along the suction port 14, and deliver it to the mounting cavity 15. It is then blown to the edge of the triangular cam 4 through the purging hole 13. As the triangular cam 4 rotates continuously, it blows the suction air into the interior of the mixture, enhances air disturbance, and improves dispersion and reaction rate. When the internal material is discharged, start the blower 16 again and keep the triangular cam 4 rotating to purge and clean the equipment inside the reaction chamber 1.

[0027] First, by using the fan 16 in the rotating shaft 3, excess water vapor in the reaction chamber 1 is drawn in when needed and re-injected into the mixture. In conjunction with the rotating triangular cam 4, the mixture is sprayed towards the area of ​​the arc-shaped guide plate 11 that compresses the mixture during the rotational spraying process. On the one hand, the water vapor blown out disturbs the steam flow, further improving the mixing effect of the mixture. On the other hand, the generated by-product water vapor is reintroduced into the mixture for secondary treatment, preventing the water vapor from carrying away some unreacted materials, improving the purity of the by-products, preventing the loss of reactants, and improving the quality of the final catalytic reaction.

[0028] The feeding assembly 8 includes a pull rod 81, a first movable plate 82, a second movable plate 83, and a sealing baffle 84. The first movable plate 82 is fixedly connected to the movable end of the pull rod 81, the second movable plate 83 is fixedly sleeved on the outer surface of the pull rod 81, and the sealing baffle 84 is fixedly connected to the other end of the pull rod 81. The first movable plate 82, the second movable plate 83, and the sealing baffle 84 are all movably sleeved inside the storage cylinder 61.

[0029] The end face of the storage component 6 is sealed by the pusher component 8. When the sealing component 7 is opened, the catalyst is removed from the storage component 6 by the intermittent elastic tension spring 72 in conjunction with the sliding pusher component 6, thus facilitating the replacement of the catalyst.

[0030] Among them, the inner side of the arc-shaped guide plate 11 is fixedly connected with the impact column 12, and the impact column 12 is symmetrically fixed on both sides of the storage cylinder 61.

[0031] By using the impact column 12 to achieve synchronous impact, the internal vibration of the reaction chamber 1 is realized, which removes the attached material and facilitates subsequent self-cleaning.

[0032] The storage cylinder 61 has auxiliary processing components 9 fixedly connected to both the upper and lower sides of its outer surface. The auxiliary processing components 9 include a connecting rod 91 and an arc plate 92. The connecting rod 91 is fixedly connected to the outer side of the storage cylinder 61, and the arc plate 92 is fixedly connected to the connecting rod 91. The arc plate 92 is located on the rotation path of the gap between the two sets of stirring plates 5, and the arc direction of the arc plate 92 and the arc guide plate 11 are opposite.

[0033] By utilizing the arrangement of the arc plate 92 of the auxiliary processing component 9, and in conjunction with the intermittent push of the triangular cam 4, the arc guide plate 11 completes the enhanced disturbance, improves the disturbance inside the reaction chamber 1, and improves the reaction efficiency.

[0034] The sealing component 7 includes an outer cylinder 71, a spring 72, and a mounting ring 73. The mounting ring 73 is fixed to the outer side of the reaction chamber 1 and sleeved on the outside of the storage cylinder 61. One end of the spring 72 is fixedly connected to the outer cylinder 71, and the other end is fixedly connected to the storage cylinder 61.

[0035] The storage component 6 is positioned and installed using the enclosed component 7, which restricts the direction of movement and provides flexible movement space. At the same time, the position of the pusher component 8 is sealed by the spring 72, thereby sealing the catalyst outlet section. It can be disassembled as needed.

[0036] The top of the reaction chamber 1 is fixedly equipped with a power motor 2. The output shaft of the power motor 2 is fixedly connected to the rotating shaft 3. The outer side of the rotating shaft 3 is fitted with a sealing sleeve, which is sealed and fixedly connected to the inner wall of the reaction chamber 1.

[0037] The rotating shaft 3 has an intake port 14 on its outer surface and an installation cavity 15 inside. The installation cavity 15 is equipped with a fan 16. The fan 16 flushes the air through the intake port 14 and inputs it into the installation cavity 15. The triangular cam 4 has a purge hole 13 on its outer side. The purge hole 13 is connected to the installation cavity 15 and corresponds to the three apex corners of the triangular cam 4.

[0038] By utilizing the suction port 14, the mounting cavity 15, and the fan 16, the generated water vapor is introduced a second time when enhanced treatment is required, thereby completing the secondary reaction and preventing residual materials from being carried away.

[0039] A catalytic method for a polyamide fiber raw material catalytic device includes the following catalytic method: Step 1: Open the feed port at the top of the reaction chamber 1, put the material to be reacted into the reaction chamber 1, seal the feed port, loosen the outer cylinder 71 in the sealing assembly 7, pull the outer cylinder 71 outward, drive the storage cylinder 61 to move outward by the spring 72, and use the opened mounting ring 73 to pull out part of the pusher assembly 8 along the inside of the storage cylinder 61. Then put the catalyst particles into the storage cylinder 61, push the pusher assembly 8 and reset it, store the catalyst particles in the storage assembly 6, and then fix the sealing assembly 7 again. Step 2: Pressurize and heat the inside of reaction chamber 1 to increase the internal pressure and temperature. The reactants begin to react under the action of high temperature and catalyst, and water is produced. The water evaporates into water vapor at high temperature. As the water vapor continues to fill the reaction chamber 1, the exhaust valve 10 is opened under high pressure, and the internal water vapor is released. Step 3: Start the power motor 2 and drive the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the stirring plate 5 and the triangular cam 4 to rotate synchronously. As the stirring plate 5 rotates, the triangular cam 4 rotates and pushes the outer arc-shaped guide plate 11 during the rotation. With the pushing action, the storage component 6 moves laterally and compresses the spring 72. The pushing component 8 in the storage component 6 simultaneously squeezes the spring 72. As the triangular cam 4 and the arc-shaped guide plate 11 are misaligned, the spring 72 drives the storage component 6 to elastically reset. The catalyst particles in the storage component 6 vibrate rapidly, completing the automatic vibration and disturbance. Step 4: When the arc-shaped guide plate 11 moves elastically back and forth, it drives the impact column 12 to move, causing the impact column 12 to collide with the inner wall of the reaction chamber 1, causing the inside of the reaction chamber 1 to vibrate and detach the material on the inner wall. Step 5: As the storage component 6 moves laterally, it drives the auxiliary processing component 9 to move synchronously. As the auxiliary processing component 9 moves, the arc plate 92 pushes the mixture to flow in the reaction chamber 1, completing further disturbance. Step 6: When it is necessary to enhance the removal of byproducts from the system during the catalytic process, start the fan 16 in the rotating shaft 3 to draw air from the reaction chamber 1 and transport it to the mounting cavity 15. The air is then blown through the purge hole 13 to the edge of the triangular cam 4, enhancing the air disturbance between the triangular cam 4 and the arc-shaped guide plate 11, thus completing the dispersion and reaction.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The reactants begin to react under the action of high temperature and catalyst and produce water. Under high temperature, the water evaporates into water vapor. As the water vapor continues to fill the reaction chamber (1), the exhaust valve (10) is opened under high pressure. The exhaust valve (10) is opened and the internal water vapor is released. Step 3: Start the power motor (2) and drive the rotating shaft (3) to rotate, so that the rotating shaft (3) drives the stirring plate (5) and the triangular cam (4) to rotate synchronously. As the stirring plate (5) rotates, the triangular cam (4) rotates and pushes the outer arc guide plate (11) during the rotation. With the pushing action, the storage component (6) moves laterally and compresses the spring (72). The pusher component (8) in the storage component (6) simultaneously squeezes the spring (72). As the triangular cam (4) and the arc guide plate (11) are misaligned, the spring (72) drives the storage component (6) to elastically reset. The catalyst particles in the storage component (6) vibrate rapidly, completing automatic vibration and disturbance. Step 4: When the arc-shaped guide plate (11) moves elastically back and forth, it drives the impact column (12) to move, causing the impact column (12) to collide with the inner wall of the reaction chamber (1), causing the inside of the reaction chamber (1) to vibrate and detach the material on the inner wall. Step 5: As the storage component (6) moves laterally, it drives the auxiliary processing component (9) to move synchronously. As the auxiliary processing component (9) moves, the arc plate (92) pushes the mixture to flow in the reaction chamber (1), completing further disturbance. Step 6: When it is necessary to enhance the removal of byproducts from the system during the catalytic process, start the blower (16) in the rotating shaft (3) to draw air from the reaction chamber (1) and transport it to the mounting cavity (15). The air is then blown through the purge hole (13) to the edge of the triangular cam (4) to enhance the air disturbance between the triangular cam (4) and the arc-shaped guide plate (11) and complete the dispersion and reaction.
