Description

Technical Field

[0001] The invention relates to the technical field of resin preparation, and in particular to a continuous preparation device for methyl silicone resin. Background Art

[0002] The continuous preparation device of methyl silicone resin is an industrial equipment for large-scale production of methyl silicone resin. It can realize continuous processing of raw materials and continuous output of products. The continuous preparation process of methyl silicone resin includes multiple complex process steps, among which the polycondensation process is a crucial link. The design of this device is specifically for the polycondensation process in the continuous preparation step, aiming to achieve high efficiency, continuity and controllability of this link, so as to ensure the preparation quality and production efficiency of methyl silicone resin.

[0003] However, compared with the prior art, there are still the following defects in specific use:

[0004] 1. In the prior art, workers usually use gas cylinders with pressure regulators to intermittently deliver inert gas to the reactor through pipelines. However, this gas delivery method not only has a complicated operation process, but also has the defect of not being able to ensure the consistency of the amount of gas delivered each time. Specifically, the intermittent addition of gas delivery requires frequent operation by workers, which not only increases the complexity of the work, but also causes operational errors due to human factors. At the same time, since the amount of gas delivered each time cannot be accurately controlled, this will have an adverse effect on the internal environment and reaction process of the reactor, thereby affecting the quality of the product and the stability of production;

[0005] 2. When the inert gas is transported to the interior of the reactor, due to the disappearance of the gas limiting effect of the transport pipeline, the inert gas entering the reactor will present an irregular diffusion pattern. As the gas continues to diffuse, its concentration distribution inside the reactor gradually becomes inconsistent, that is, there are significant differences in gas concentrations in different areas, and the problem of uneven gas dispersion further aggravates the inconsistency of concentration distribution. Due to the randomness of gas molecules in the diffusion process and the complexity of the internal structure of the reactor, it is often difficult for the gas to achieve a uniform distribution state. This uneven distribution state cannot achieve full coverage and protection of the reaction products, which will affect the chemical reaction efficiency inside the reactor and have an adverse effect on the quality and yield of the reaction products.

[0006] 3. In the polycondensation process inside the existing equipment, since the raw materials usually contain solid components, these solid raw materials will have a significant resistance effect on the stirring shaft in the initial stirring stage. Specifically, when the stirring shaft starts to rotate and tries to mix the solid raw materials with liquid or gaseous components, the particles or lumps of the solid raw materials will directly rub and collide with the surface of the stirring shaft, causing the resistance of the stirring shaft to rise sharply. As the stirring process continues, the torque between the motor output shaft and the stirring shaft will gradually increase. In addition, while overcoming the resistance of the solid raw materials, the stirring shaft also needs to drive the entire material in the reactor to mix. Therefore, as the stirring intensity increases and the stirring time prolongs, the torque required to be provided by the motor output shaft will also increase accordingly, resulting in unstable rotation stirring, affecting the stirring efficiency and mixing uniformity;

[0007] In view of this, the present invention proposes a continuous preparation device for methyl silicone resin to make up for and improve the deficiencies of the prior art. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a continuous preparation device for methyl silicone resin to solve the technical problems raised in the above background technology.

[0014] Furthermore, both sides of the partition plate are provided with sliding grooves, and the pressure plate is fixedly connected with sliding balls at positions corresponding to the sliding grooves, and the partition plate and the pressure plate are slidably connected through the sliding grooves and the sliding balls.

[0015] Furthermore, the limiting collar is integrally installed at a spacing position between the partition plate and the bottom of the inner side wall of the refilling bin, and the limiting collar is integrally made of a transparent material.

[0016] Furthermore, the lower end of the gas cylinder is in the shape of an outwardly expanding funnel, the inner diameter of the swirl plate is equal to the inner diameter of the gas cylinder, and the outer circle of the swirl plate is in the shape of an inclined spiral as a whole, and inert gas is stored inside the refilling bin and the gas cylinder.

[0017] Furthermore, the anti-torsion protection mechanism is fixedly connected to a groove ring on the outer wall of the output shaft end of the driving motor, the outer wall of the groove ring is rotatably connected to a three-dimensional positioning frame, the lower surface of the groove ring is fixedly connected to a screw rod, the outer wall of the screw rod is threadedly connected to a bump ring, the lower surface of the bump ring is fixedly connected to a telescopic shaft, the telescopic shaft is fixedly connected to the upper end of the stirring shaft, and the inner cavity bottom of the telescopic shaft is evenly fixedly connected to an elastic rope.

[0018] Furthermore, a ball screw structure is formed between the screw rod and the lug ring, and the lug ring and the screw rod are initially in a staggered meshing state.

[0019] Furthermore, the stereotaxic frame as a whole is composed of two rectangular frames, and the stereotaxic frame as a whole is in a symmetrical cross shape.

[0020] Furthermore, the elastic rope is entirely made of a hydrophobic polyurea-urethane material, and the upper and lower ends of the elastic rope are fixedly connected to the telescopic shaft and the bump ring respectively.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) In order to solve the problem of difficult control of gas delivery in the prior art, the present device installs a metering bin above the reactor, and the delivery pipe and gas cylinder connected thereto are both equipped with one-way valves, thereby forming a set of precise continuous delivery processes, and using the change of pressure gradient as a drive to ensure the continuous and quantitative delivery of inert gas. More importantly, a pressure plate is provided inside the metering bin. As a key component for pressure balance, it can automatically adjust its position according to the delivery change of the pressure inside the metering bin to ensure the stability of the pressure inside the metering bin. This design not only effectively prevents the gas from scattering due to the increase of the remaining space inside the metering bin, but also ensures that the amount of inert gas output each time remains consistent within a small range, thereby greatly improving the controllability of the reaction process and the quality stability of the product;

[0023] Compared with the traditional intermittent delivery method, the continuous inert gas delivery adopted by this device significantly reduces the complexity of operation and the influence of human factors on the operation accuracy. The continuity and accuracy of the delivery process are achieved through automatic control, and the delivery amount of the inert gas can be accurately controlled, ensuring the stability of the internal environment of the reactor and the controllability of the reaction process.

[0024] (2) In order to solve the problem of inconsistent concentrations of inert gases at different heights after long-term storage in the prior art, the present device is designed such that when the inert gas passes through the delivery pipe, its flow will drive the rotating blades of the equalizer to keep rotating. This rotation process effectively breaks the stratified state of the gas through physical disturbance, and promotes the full mixing of gases of different concentrations, thereby ensuring that the gas delivered to the inside of the gas cylinder has uniform concentration and quality, effectively enhancing the controllability of the reaction process, and providing a more stable and uniform gas environment for the continuous preparation process;

[0025] In order to solve the problem of irregular diffusion of gas inside the reactor in the prior art, the present device uses the special structure of the swirl plate to divide the gas into two flow paths when entering the reactor. One part flows directly out from the inside of the swirl plate, and the other part flows along the spiral groove on the outer wall of the swirl plate to form a swirl effect. When the gas flows along the spiral groove of the swirl plate, it will obtain a certain angular momentum. According to the principle of conservation of angular momentum, this part of the gas will continue to maintain its rotation state after leaving the swirl plate to form a swirl. This rotational motion can promote the mixing and diffusion of the gas with the inner wall of the reactor and the reaction medium, and the flow pattern can effectively enhance the diffusion uniformity of the gas inside the reactor. The uniformity of gas distribution directly affects the efficiency of the chemical reaction. The swirl technology optimizes the gas distribution and provides a more uniform inert gas environment for the reactants, which helps to increase the reaction rate and product selectivity, thereby significantly improving the overall efficiency of the chemical reaction.

[0026] (3) The present device realizes a meshing active connection between the groove ring and the protrusion ring through the cooperation between the groove ring and the protrusion ring. Through the cooperation between the groove ring and the protrusion ring, the torque is evenly distributed at multiple contact points. This multi-point contact meshing connection can effectively disperse the torque in space, reduce the torque borne by a single contact point, and thus reduce the load on the motor output shaft end. Compared with the traditional connection between the stirring shaft and the motor output shaft, such as direct rigid connection or partial sliding connection, which will cause energy loss during the transmission process, the meshing connection between the groove ring and the protrusion ring reduces energy loss by reducing unnecessary sliding and friction, thereby reducing the additional torque force required by the motor to overcome these losses. It not only provides a more stable connection, but also enhances the torque resistance of the entire device. This means that even if the resistance of the solid raw material is encountered during the stirring process, the connection structure can maintain a good torque transmission efficiency and avoid the impact of the sudden increase in torque on the motor output shaft.

[0027] In addition, when the output shaft of the above-mentioned motor drives the screw to rotate, it will trigger the pulling of the elastic rope to put it in a taut and twisted state. The taut and twisted state of the elastic rope increases the rigidity of the connecting parts and reduces the gap between the two, ensuring that the meshing between the groove ring and the protrusion ring is tighter and more stable, avoiding the instability caused by looseness and gap during the stirring process, and during the stirring process, the elasticity of the elastic rope can absorb and slow down the vibration generated when the solid raw material contacts the stirring shaft, avoiding the vibration from being transmitted to the motor, protecting the motor and the transmission system, and also reducing the vibration of the stirring shaft to improve the stability of the stirring process. At the same time, the taut state of the elastic rope helps to maintain the uniformity of torque transmission, and even when encountering resistance from the solid raw material, it can ensure smooth transmission of torque and avoid sudden increase or decrease of torque.

The inside of the gas cylinder 27 is fixedly connected with a swirl plate 28, and both sides of the partition plate 22 are provided with a slide groove. The pressure plate 23 is fixedly connected with a slide ball at the position corresponding to the slide groove. The partition plate 22 and the pressure plate 23 are slidably connected through the slide groove and the slide ball. The limiting collar 24 is integrally installed at the interval between the partition plate 22 and the bottom of the inner wall of the refilling bin 21, and the collar part of the limiting collar 24 is made of a transparent material as a whole. The lower end of the gas delivery cylinder 27 is in the shape of an outwardly expanding funnel. The inner circle diameter of the swirl plate 28 is equal to the inner circle diameter of the gas delivery cylinder 27, and the outer circle of the swirl plate 28 is in the shape of an inclined spiral as a whole. Inert gas is stored in the refilling bin 21 and the gas delivery cylinder 27.

[0042] Specifically, when the inert gas is discharged from the gas delivery cylinder 27 to the inside of the reactor 11 again, it will be divided into two flow paths by the swirl plate 28, one part flows directly out from the inside of the swirl plate 28, and the other part flows along the spiral groove of the outer wall of the swirl plate 28 to form a swirl effect. When the gas flows along the spiral groove of the swirl plate 28, it will obtain a certain angular momentum. According to the principle of conservation of angular momentum, this part of the gas will continue to maintain its rotation state after leaving the swirl plate 28 to form a swirl. This rotational motion can promote the mixing and diffusion between the inert gas and the inner wall of the reactor 11 and the reaction medium, thereby helping to increase the reaction rate and product selectivity, thereby significantly improving the overall efficiency of the chemical reaction;

[0043] Please refer to Figure 6 - Fig. 9As shown, the anti-torsion protection mechanism 3 is fixedly connected to the groove ring 31 on the outer wall of the output shaft end of the driving motor 12, the outer wall of the groove ring 31 is rotatably connected to the stereo positioning frame 32, the lower surface of the groove ring 31 is fixedly connected to the screw rod 33, the outer wall of the screw rod 33 is threadedly connected to the bump ring 34, the lower surface of the bump ring 34 is fixedly connected to the telescopic shaft 35, the telescopic shaft 35 is fixedly connected to the upper end of the stirring shaft 13, the inner cavity bottom of the telescopic shaft 35 is evenly fixedly connected with an elastic cable 36, a ball screw structure is formed between the screw rod 33 and the bump ring 34, and the bump ring 34 and the screw rod 33 are initially in a staggered meshing state, the stereo positioning frame 32 is composed of two rectangular frames, and the stereo positioning frame 32 is symmetrically cross-shaped, the elastic cable 36 is made of hydrophobic polyurea-urethane material, and the upper and lower ends of the elastic cable 36 are respectively fixedly connected to the telescopic shaft 35 and the bump ring 34;

[0044] Specifically, through the structural coordination between the groove ring 31 and the bump ring 34, the torque can be evenly distributed at multiple contact points, and this multi-point contact meshing connection can effectively disperse the torque in space, reduce the torque borne by a single contact point, thereby reducing the load on the output shaft end of the drive motor 12, and the meshing connection between the groove ring 31 and the bump ring 34 can also reduce unnecessary sliding and friction and reduce energy loss, thereby providing a more stable connection;

[0045] The following are the complete usage steps and working principles of the above embodiment:

[0046] The use process of the device is as follows: first, the staff checks the device to ensure that the drive motor 12 and the stirring shaft 13 and other components are in good condition, adjusts the speed and stirring time of the stirring shaft 13 as needed, then puts the required raw materials into the reactor 11 in sequence, and finally starts the drive motor 12 to fully mix the raw materials in the reactor 11;

[0047] The quantitative delivery mechanism 2 for quantitatively delivering the inert gas to the inside of the reactor 11 and making the inert gas uniformly cover and circulate is specifically used as follows:

[0048] Since a refilling bin 21 is installed above the reactor 11, and the delivery pipe 25 and the gas cylinder 27 connected thereto are both equipped with a one-way connected one-way valve 26, when the inert gas in the gas cylinder 27 is released and discharged into the reactor 11, its internal pressure will gradually decrease. At the same time, the refilling bin 21, as a gas replenishment source, has a relatively high internal gas pressure, and since a one-way valve 26 is installed between the two, it allows the gas to flow from the refilling bin 21 to the gas cylinder 27 under the action of the pressure difference, but prevents the gas from flowing in the opposite direction. Therefore, when the gas in the gas cylinder 27 is released and the internal pressure drops, the high-pressure gas in the refilling bin 21 will automatically enter the gas cylinder 27 through the one-way valve 26 to replenish the gas inside it and restore a certain pressure level.

[0049] like Figure 2 and Figure 3 As shown, since both sides of the partition plate 22 are provided with slide grooves, and the pressure plate 23 is fixedly connected with slide balls at the positions corresponding to the slide grooves, and the partition plate 22 and the pressure plate 23 are slidably connected through the slide grooves and the slide balls, when the above-mentioned refilling bin 21 transports the inert gas to the inside of the gas cylinder 27, as the pressure inside the refilling bin 21 continues to decrease, the pressure plate 23 will slide downward along the surface of the partition plate 22, and then it can automatically adjust its position according to the transport change of the internal pressure of the refilling bin 21, so as to ensure the stability of the internal pressure of the refilling bin 21. This design not only effectively prevents the gas from scattering due to the increase of the remaining space in the refilling bin 21, but also ensures that the amount of inert gas output each time remains consistent within a small range, thereby greatly improving the controllability of the reaction process and the quality stability of the product;

[0050] like Figure 4 and Figure 5As shown, since the internal rotation of the delivery pipe 25 near one end of the refilling chamber 21 is connected to the equalizer 2501, when the inert gas passes through the delivery pipe 25, its flow will drive the rotating blades of the equalizer 2501 to keep rotating. This rotation process effectively breaks the stratified state of the gas through physical disturbance, and promotes the full mixing of gases of different concentrations, thereby ensuring that the gas delivered to the inside of the gas cylinder 27 has a uniform concentration and quality, effectively enhancing the controllability of the reaction process, and providing a more stable and uniform gas environment for the continuous preparation process. In addition, since the lower end of the gas cylinder 27 is in the shape of a funnel that expands outward, the inner circle diameter of the swirl plate 28 is equal to the inner circle diameter of the gas cylinder 27, and the outer circle of the swirl plate 28 is inclined as a whole. Spiral shape, so when the inert gas is discharged from the gas cylinder 27 to the inside of the reactor 11 again, it will be divided into two flow paths by the swirl plate 28, one part flows directly out from the inside of the swirl plate 28, and the other part flows along the spiral groove of the outer wall of the swirl plate 28 to form a swirl effect. When the gas flows along the spiral groove of the swirl plate 28, it will obtain a certain angular momentum. According to the principle of conservation of angular momentum, this part of the gas will continue to maintain its rotation state after leaving the swirl plate 28 to form a swirl. This rotational motion can promote the mixing and diffusion of the inert gas with the inner wall of the reactor 11 and the reaction medium, thereby achieving comprehensive coverage protection, which helps to improve the reaction rate and product selectivity, thereby significantly improving the overall efficiency of the chemical reaction;

[0051] The anti-torsion protection mechanism 3 is used to increase the anti-torsion force between the driving motor 12 and the stirring shaft 13 and to perform shock-absorbing treatment on the stirring shaft 13 as a whole. When used specifically:

[0052] like Figure 7 As shown, the output shaft of the driving motor 12 is movably engaged with the stirring shaft 13 through a groove ring 31 and a bump ring 34. Figure 8 As shown, a ball screw structure is formed between the lead screw 33 and the lug ring 34, and the lug ring 34 and the groove ring 31 are initially in an interlaced meshing state. Therefore, when the drive motor 12 starts to drive the lead screw 33 to rotate, it will simultaneously drive the lug ring 34 to move upward, and then form a complete fit with the groove ring 31. Through the structural cooperation between the groove ring 31 and the lug ring 34, multiple contact points can achieve uniform distribution of torque, and this multi-point contact meshing connection can effectively disperse the torque in space, reduce the torque borne by a single contact point, thereby reducing the load on the output shaft end of the drive motor 12, and the meshing connection between the groove ring 31 and the lug ring 34 can also reduce unnecessary sliding and friction and reduce energy loss, thereby providing a more stable connection, which means that even if the resistance of the solid raw material is encountered during the mixing process, the connection structure can maintain good torque transmission efficiency, avoiding the impact of the sudden increase of torque on the output shaft of the drive motor 12.

[0053] like Fig. 9 As shown, the upper and lower ends of the elastic rope 36 are fixedly connected to the telescopic shaft 35 and the bump ring 34 respectively. Therefore, when the bump ring 34 moves upward, it will synchronously pull the elastic rope 36, thereby converting it into a torsional tension state. The tensioned torsional state of the elastic rope 36 increases the rigidity of the connecting component, reduces the gap between the groove ring 31 and the bump ring 34, and avoids the instability caused by looseness and gap during the stirring process. In addition, during the stirring process, the elasticity of the elastic rope 36 itself can absorb and slow down the vibration generated when the solid raw material contacts the stirring shaft 13, avoiding the vibration from being transmitted to the drive motor 12, thereby ensuring the smooth transmission of torque and avoiding a sudden increase or decrease in torque.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
