Description

Technical Field

[0001] The present invention relates to the field of chemical equipment, and specifically relates to an anti-hanging material reaction kettle for preparing spherical micro-powder by liquid phase method. Background Art

[0002] When preparing spherical micro-powder by liquid phase method, a variety of liquid solvents and reactants are put into the reaction kettle through the feed inlet for mixing. If these liquids hang on the reaction wall along the feed inlet during the input process, especially in the area that cannot be covered by the stirrer, it may lead to uneven local concentration and incomplete reaction, thus affecting the product quality and production efficiency.

[0003] Currently, a disclosed reactor for preparing silica with the Chinese authorized announcement number of CN108190898B includes a protective shell and a combustion chamber fixed inside the protective shell. The central axis of the protective shell is parallel to the central axis of the combustion chamber. One end of the protective shell is an inlet, and the other end is an outlet. The partition plate arranged in the combustion chamber divides the combustion chamber from the inlet to the outlet direction into a pipeline chamber and a combustion chamber. The end of the combustion chamber facing the outlet is set as an opening. The inner wall of the combustion chamber near the partition plate is provided with an air port. The outside of the protective shell is connected with a chlorosilane sampling spray pipe and an alcohol-based fuel sampling spray pipe. The chlorosilane sampling spray pipe and the alcohol-based fuel sampling spray pipe sequentially pass through the protective shell, the inner wall of the pipeline chamber, and the partition plate.

[0004] According to the above patent, the patent narrows the outlet of the protective shell to increase the flow rate and prevent the product from hanging on the wall. However, during the feeding process, due to factors such as local turbulence, improper feeding speed and direction, the material may still hang on the inner wall. This causes the material to directly impact the wall surface or deposit in the low flow rate area during feeding, forming hanging material, which affects the reaction uniformity and product quality. Merely relying on narrowing the outlet cannot completely solve the problem of hanging material. Therefore, there is a need for an anti-hanging material reaction kettle that can enable the raw materials to quickly enter the reaction area, while avoiding the raw materials from hanging on the inner wall of the non-working area during feeding, ensuring the uniform distribution of the raw materials and improving the overall reaction efficiency and product quality. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, an anti-hanging material reaction kettle for preparing spherical micro-powder by liquid phase method is provided. Through the synergistic effect of an inverted conical drainage plate, a positive conical baffle plate and an enclosure structure, it prevents the raw materials from contacting the inner wall of the reaction kettle body in the upper half feeding area. At the same time, the vibration of the inverted conical drainage plate and its cooperation with the enclosure structure cause the raw materials to be continuously disturbed during the flowing process, prevent stable attachment, and promote rapid flow to the blanking channel.

[0006] To solve the problems of the existing technology, the present invention provides an anti-hanging material reaction kettle for preparing spherical micropowder by a liquid phase method, which includes a reaction kettle body. The reaction kettle body has a feed inlet and a discharge outlet. A stirrer is provided in the reaction kettle body. An anti-hanging material drainage component is also provided in the reaction kettle body. The anti-hanging material drainage component divides the inner cavity of the reaction kettle body into an upper half feeding area and a lower half reaction area. The anti-hanging material drainage component includes an inverted conical drainage plate and a positive conical centrifugal disk. The inverted conical drainage plate has a sleeve sleeved on the positive conical centrifugal disk. A blanking channel for raw materials to enter the lower half reaction area is formed between the sleeve and the positive conical centrifugal disk. A drainage pipe extending into the upper half feeding area through the feed inlet is provided on the reaction kettle body. The extending end of the drainage pipe extends towards the direction close to the blanking channel.

[0007] Preferably, the anti-hanging material drainage component further includes a positive conical baffle plate arranged directly above the inverted conical drainage plate and an enclosing structure arranged between the positive conical baffle plate and the inverted conical drainage plate. The upper half feeding area is formed between the positive conical baffle plate, the inverted conical drainage plate and the enclosing structure.

[0008] Preferably, the inverted conical drainage plate can vibrate up and down relative to the positive conical baffle plate. When the inverted conical drainage plate vibrates, the raw materials sliding up and down are in a continuously disturbed state, so that the raw materials flow rapidly towards the direction of the blanking channel.

[0009] Preferably, the enclosing structure is specifically a metal bellows that can adapt to the vibration of the inverted conical drainage plate. When the metal bellows continuously deforms with the vibration of the inverted conical drainage plate, the raw materials attached to the metal bellows are also in a continuously disturbed state.

[0010] Preferably, an upper scraping rod and a lower scraping rod that can follow the action of the stirrer to scrape the walls of the positive conical baffle plate and the inverted conical drainage plate respectively are provided in the upper half feeding area.

[0011] Preferably, an activity gap for the vibration of the inverted conical drainage plate is left between the lower scraping rod and the inverted conical drainage plate. A rubber scraping strip that can adapt to the vibration of the inverted conical drainage plate is provided on the lower scraping rod.

[0012] Preferably, the positive conical baffle plate and the inverted conical drainage plate respectively have an upper heating interlayer and a lower heating interlayer for introducing hot air.

[0013] Preferably, an air supply pipe for providing hot air is connected and communicated between the drainage pipe and the upper heating interlayer. The air supply pipe has an air inlet and an air outlet. A ventilation pipe is connected and communicated between the upper heating interlayer and the lower heating interlayer.

[0014] Preferably, the drainage pipe has a pipe interface. A spiral feeder for preventing raw materials from adhering to the inner wall is provided in the drainage pipe.

[0015] Preferably, the positive conical centrifugal disk can rotate relative to the sleeve following the movement of the stirrer. When the positive conical centrifugal disk rotates, the raw materials flowing in the blanking channel are in a rapidly dispersed state under the action of centrifugal force.

[0016] The beneficial effects of this application compared with the prior art are as follows: 1. By combining the inverted conical drainage plate, the positive conical baffle plate and the surrounding structure, the present invention achieves the effect of highly efficient anti-hanging material during the process of raw materials entering the reaction kettle body. In this process, the inverted conical drainage plate guides the raw materials to slide obliquely downward to avoid directly impacting the inner wall. The surrounding structure isolates the contact between the raw materials and the side wall of the reaction kettle, while the positive conical baffle plate prevents the raw materials from splashing upward or contacting the top, ensuring that the raw materials flow concentratedly along the predetermined path.

[0017] The risk of hanging materials in the upper half feeding area is minimized, ensuring that the raw materials smoothly enter the lower half reaction area for chemical reactions, thereby improving the continuity and efficiency of production, and ensuring the quality of the final product and the stability of the production process.

[0018] 2. Through the vibration of the inverted conical drainage plate and its synergistic effect with the metal bellows, the raw materials are continuously disturbed during the flowing process, preventing the occurrence of any stable adhesion phenomenon, and promoting the raw materials to flow rapidly towards the blanking channel direction, effectively reducing the risk of hanging materials.

[0019] At the same time, the upper scraping wall rod and the lower scraping wall rod move closely along the surfaces of the positive conical baffle plate and the inverted conical drainage plate, continuously scraping off the possibly adhered raw materials, keeping the surfaces clean and preventing the accumulation of raw materials. Combining the vibration and scraping wall methods not only increases the sliding speed of the raw materials but also maximally prevents the occurrence of hanging materials, ensuring the continuity and efficiency of production.

[0020] 3. By respectively equipping the upper heating sandwich layer and the lower heating sandwich layer on the positive conical baffle plate and the inverted conical drainage plate and introducing hot air into them, the surface temperature is effectively increased, and the adhesion of the raw materials on them is reduced. It is ensured that when the raw materials contact the heated surface, they do not rapidly cool and solidify but remain in a flowing state, thereby reducing the possibility of hanging materials.

[0021] At the same time, for the raw materials that have already started to adhere, heating can also help soften them, making it easier for them to slide into the blanking channel, ensuring that the raw materials flow smoothly into the lower half reaction area, effectively preventing the occurrence of hanging materials, and improving the continuity and efficiency of production.

[0033] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] See Figures 1 - 5 As shown, a reaction kettle for preventing material hanging in the preparation of spherical micro-powder by liquid phase method includes a reaction kettle body 1, the reaction kettle body 1 has a feed inlet and a discharge outlet 11, a stirrer 2 is arranged in the reaction kettle body 1, and an anti-hanging material drainage component is also arranged in the reaction kettle body 1. The anti-hanging material drainage component divides the inner cavity of the reaction kettle body 1 into an upper half feeding area 12 and a lower half reaction area 13. The anti-hanging material drainage component includes an inverted conical drainage plate 3 and a positive conical centrifugal disc 4. The inverted conical drainage plate 3 has a sleeve 31 sleeved on the positive conical centrifugal disc 4. A blanking channel 311 for raw materials to enter the lower half reaction area 13 is formed between the sleeve 31 and the positive conical centrifugal disc 4. A drainage pipe 121 extending into the upper half feeding area 12 through the feed inlet is arranged on the reaction kettle body 1, and the extending end of the drainage pipe 121 extends towards the direction close to the blanking channel 311.

[0035] The stirrer 2 has a rotating shaft 21 and stirring rods 22 arranged thereon and in contact with the inner wall of the reaction kettle body 1. The stirring rods 22 are located in the lower half reaction area 13. A rotating motor for driving the rotation of the rotating shaft 21 is arranged on the reaction kettle body 1.

[0036] When starting the liquid phase preparation process of spherical micro-powder, the raw materials are first guided to the upper half feeding area 12 inside the reaction kettle body 1 through the drainage pipe 121 at the top of the reaction kettle body 1. Since the extending end of the drainage pipe 121 extends towards the blanking channel 311 formed between the inverted conical drainage plate 3 and the positive conical centrifugal disc 4, it is ensured that the inner wall of the upper half feeding area 12 of the reaction kettle body 1 is far away, preventing the occurrence of material hanging during the feeding process.

[0037] As the raw materials gradually approach and enter the blanking channel 311, the inverted conical drainage plate 3 and the positive conical centrifugal disc 4 enable any raw materials that may adhere to the inner wall of the upper half feeding area 12 of the reaction kettle body 1 to slide smoothly, preventing the accumulation of raw materials. Specifically, the narrow space formed between the sleeve 31 sleeved on the positive conical centrifugal disc 4 and the centrifugal disc serves as the blanking channel 311, which limits the flow path of the raw materials while promoting the continuous falling of the raw materials, reducing the phenomenon of raw material retention caused by uneven flow rate or improper angle, thereby maintaining a smooth and efficient raw material transmission process during the entire feeding stage and maximizing the avoidance of material hanging problems.

[0038] Next, the raw materials slowly move along the drainage pipe 121 until they approach the entrance of the blanking channel 311 formed by the inverted conical drainage plate 3 and the positive conical centrifugal disc 4. As the raw materials gradually approach and finally pass through the blanking channel 311, they are evenly dispersed and ready to enter the reaction stage.

[0039] Once the raw materials successfully pass through the blanking channel 311, they enter the lower half reaction zone 13. At this time, the rotating shaft 21 of the stirrer 2 drives the stirring rod 22. With the continuous operation of the stirrer 2, the raw materials are continuously dispersed and reorganized in the lower half reaction zone 13, forming a dynamic equilibrium state. In this state, the various components in the raw materials come into full contact, and the chemical reaction proceeds efficiently. The stirring rod 22 in contact with the inner wall of the reaction kettle body 1 effectively reduces the occurrence of material hanging.

[0040] Finally, after the chemical reaction is completed, the spherical micro-powder product generated will be discharged from the reaction kettle through the discharge port 11.

[0041] See Figures 2 - 5 As shown, the anti-material-hanging drainage assembly further includes a positive conical baffle plate 5 arranged directly above the inverted conical drainage plate 3 and an enclosure structure 6 arranged between the positive conical baffle plate 5 and the inverted conical drainage plate 3. The upper half feeding area 12 is formed between the positive conical baffle plate 5, the inverted conical drainage plate 3 and the enclosure structure 6.

[0042] The positive conical baffle plate 5 is provided with a through hole for the drainage pipe 121 to pass through.

[0043] When the raw materials enter the upper half feeding area 12 through the drainage pipe 121, they first encounter the inverted conical drainage plate 3, which guides the raw materials to slide down along its inclined surface, effectively avoiding the material hanging phenomenon caused by the raw materials directly impacting the inner wall of the reaction kettle body 1.

[0044] During the sliding process of the raw materials, the enclosure structure 6 forms a physical barrier between the positive conical baffle and the inverted conical drainage plate 3, separating the raw material flow path from the side wall of the reaction kettle body 1, thereby preventing the raw materials from coming into contact with and adhering to the side wall during the falling process.

[0045] At the same time, the positive conical baffle plate 5 is located directly above the inverted conical drainage plate 3, blocking the possibility of the raw materials splashing upward or directly contacting the top of the reaction kettle body 1, ensuring that all the raw materials entering the feeding area can be concentrated and flow downward along the predetermined path.

[0046] By precisely controlling the flow direction of the raw materials and utilizing the synergistic effect of the inverted conical drainage plate 3, the surrounding structure 6, and the positive conical baffle plate 5, the adhesion of the raw materials to any position on the inner wall of the reactor in the upper feeding area 12 is effectively prevented, minimizing the risk of material hanging. Therefore, throughout the process, from the input of the raw materials to their smooth entry into the lower reaction area 13, the possibility of material hanging is reduced, ensuring the quality and efficiency of production.

[0047] See Figures 2 - 9 As shown, the inverted conical drainage plate 3 can vibrate up and down relative to the positive conical baffle plate 5. When the inverted conical drainage plate 3 vibrates, the raw materials sliding up and down on it are in a continuously disturbed state, causing the raw materials to flow rapidly in the direction of the blanking channel 311.

[0048] A vibration generator 32 for driving the vibration of the inverted conical drainage plate 3 is provided on the reactor body 1.

[0049] A buffer gasket 33 for preventing collision is provided between the positive conical baffle plate 5 and the inverted conical drainage plate 3.

[0050] When the inverted conical drainage plate 3 vibrates, the raw materials on it are in a continuously disturbed state. The continuous disturbance makes it impossible for the raw materials to stably adhere to any surface and promotes the raw materials to flow rapidly in the direction of the blanking channel 311, effectively preventing the occurrence of material hanging.

[0051] At the same time, the buffer gasket 33 provided between the positive conical baffle plate 5 and the inverted conical drainage plate 3 avoids direct collision between the two, ensuring safe operation and maintaining the stability of the vibration process, further ensuring that the raw materials can pass smoothly through the blanking channel 311 and reducing the risk of material hanging.

[0052] See Figures 2 - 9 As shown, the surrounding structure 6 is specifically a metal bellows that can adapt to the vibration of the inverted conical drainage plate 3. When the metal bellows continuously deforms with the vibration of the inverted conical drainage plate 3, the raw materials attached to the metal bellows are also in a continuously disturbed state.

[0053] When the inverted conical drainage plate 3 vibrates up and down, the metal bellows continuously deforms. The deformation makes the raw materials attached to the metal bellows also in a continuously disturbed state, preventing the stable adhesion of the raw materials at any position.

[0054] During the vibration process, the originally attached raw materials are continuously shaken off and redistributed, ensuring their smooth flow in the direction of the blanking channel 311, thereby effectively reducing the possibility of material hanging. The dynamic adaptability of the metal bellows not only ensures the continuity of the raw material flow but also greatly avoids the material hanging problem caused by the retention of raw materials.

[0055] See Figures 3 - 10 As shown, in the upper feeding area 12, there are an upper scraping rod 211 and a lower scraping rod 212 that can follow the movement of the stirrer 2 to scrape the walls of the positive conical baffle 5 and the inverted conical drainage plate 3 respectively.

[0056] When the stirrer 2 operates, the upper scraping rod 211 moves closely along the surface of the positive conical baffle 5, while the lower scraping rod 212 moves closely along the surface of the inverted conical drainage plate 3. The two sets of scraping rods continuously scrape off the raw materials that may adhere to the surfaces of the positive conical baffle 5 and the inverted conical drainage plate 3, ensuring that any raw materials attempting to accumulate on these surfaces can be promptly removed and preventing the accumulation of raw materials.

[0057] Through the operation of the stirrer 2 in cooperation with the upper scraping rod 211 and the lower scraping rod 212, the surfaces of the positive conical baffle 5 and the inverted conical drainage plate 3 are effectively kept clean, minimizing the phenomenon of material hanging.

[0058] See 8 - Figure 10 As shown, there is a clearance for the vibration of the inverted conical drainage plate 3 between the lower scraping rod 212 and the inverted conical drainage plate 3, and a rubber scraping strip 2121 that can adapt to the vibration of the inverted conical drainage plate 3 is provided on the lower scraping rod 212.

[0059] When the stirrer 2 drives the lower scraping rod 212 to move, the rubber scraping strip 2121 will slide along the surface of the inverted conical drainage plate 3, effectively scraping off the possibly remaining raw materials and avoiding the accumulation and hardening of raw materials.

[0060] In addition, since the rubber scraping strip 2121 can adapt to the vibration frequency and amplitude of the inverted conical drainage plate 3, it can, while ensuring effective wall scraping, not interfere with the normal vibration of the inverted conical drainage plate 3. This enables the inverted conical drainage plate 3 to vibrate efficiently while minimizing the occurrence of the material hanging phenomenon.

[0061] Combining the methods of vibration and wall scraping maximally prevents the raw materials sliding down on the inverted conical drainage plate 3, increases the sliding speed while preventing the occurrence of material hanging.

[0062] See Figures 3 - 5 and Figure 8 As shown, the positive conical baffle 5 and the inverted conical drainage plate 3 respectively have an upper heating sandwich layer 51 and a lower heating sandwich layer 34 for introducing hot air.

[0063] Due to the upper heating interlayer 51 and the lower heating interlayer 34 respectively equipped on the positive conical baffle 5 and the inverted conical drainage plate 3, the surfaces of the positive conical baffle 5 and the inverted conical drainage plate 3 are heated by passing hot air into the upper heating interlayer 51 and the lower heating interlayer 34. Heating can effectively prevent raw materials from accumulating on the surface, because the hot air raises the surface temperature of the baffle and the drainage plate, thereby reducing the adhesion of raw materials to its surface.

[0064] Specifically, when the raw materials come into contact with the heated surface, the raw materials do not quickly cool and solidify, but remain in a flowing state, reducing the possibility of material hanging. In addition, heating can also help soften the raw materials that have already adhered to the surface, making it easier for them to naturally slide into the blanking channel 311, further ensuring that the raw materials can flow smoothly into the lower half reaction zone 13 without hindrance, avoiding the reduction of production efficiency and product quality problems caused by material hanging.

[0065] See Figures 3 - 5 and Figure 8 As shown, a gas supply pipe 122 for providing hot air is connected between the drainage pipe 121 and the upper heating interlayer 51. The gas supply pipe 122 has an air inlet 1221 and an air outlet 1222, and a ventilation pipe 123 is connected between the upper heating interlayer 51 and the lower heating interlayer 34.

[0066] The ventilation pipe 123 is fixedly connected to the positive conical baffle 5, and the lower end of the ventilation pipe 123 vertically penetrates the inverted conical drainage plate 3 and extends into the lower heating interlayer 34.

[0067] The inverted conical drainage plate 3 can move along the ventilation pipe 123, and an anti - detachment head 1231 for supporting the inverted conical drainage plate 3 is provided at the lower end of the ventilation pipe 123.

[0068] The connection between the drainage pipe 121 and the upper heating interlayer 51 through the gas supply pipe 122 provides hot air to the upper heating interlayer 51 of the positive conical baffle 5, and the upper heating interlayer 51 and the lower heating interlayer 34 are connected through the ventilation pipe 123 to ensure that the hot air can be transferred from the upper heating interlayer 51 to the lower heating interlayer 34, thereby heating the inverted conical drainage plate 3.

[0069] Since the inverted conical drainage plate 3 can move up and down along the ventilation pipe 123, it provides a guiding effect for the vibration direction of the inverted conical drainage plate 3, ensuring the stability and reliability of the vibration. In order to prevent the inverted conical drainage plate 3 from falling off during vibration, the anti - detachment head 1231 provided at the lower end of the ventilation pipe 123 ensures the stability.

[0070] With the start of heating, the surfaces of the positive conical baffle plate 5 and the inverted conical drainage plate 3 are maintained at a suitable temperature, reducing the adhesion of raw materials on their surfaces, making it difficult for raw materials to accumulate and hang, and enabling them to flow smoothly towards the blanking channel 311, effectively preventing the occurrence of material hanging phenomenon.

[0071] See Figures 1 - 4 As shown, the drainage pipeline 121 has a pipe interface 1211, and a spiral feeder 1212 for preventing raw materials from adhering to its inner wall is provided in the drainage pipeline 121.

[0072] When the raw materials enter the drainage pipeline 121 through the pipe interface 1211, the spiral feeder 1212 starts to work. It not only provides the driving force for the raw materials to move forward, but also generates a scraping effect on the inner wall through its rotational movement, which can destroy the adhesion between the raw materials and the inner wall of the drainage pipeline 121, making it impossible for the raw materials to stably adhere to the surface.

[0073] With the continuous rotation and advancement of the spiral feeder 1212, the raw materials are continuously transported from the pipe interface 1211 to the vicinity of the inverted conical drainage plate 3 and flow towards the blanking channel 311, reducing the risk of raw material accumulation in the drainage pipeline 121 and ensuring the smoothness of raw material flow and the continuity of production.

[0074] See Figures 2 - 4 and Figures 7 - 9 As shown, the positive conical centrifugal disk 4 can rotate relative to the sleeve 31 following the movement of the stirrer 2. When the positive conical centrifugal disk 4 rotates, the raw materials flowing in the blanking channel 311 are in a rapidly dispersed state under the action of centrifugal force.

[0075] When the positive conical centrifugal disk 4 rotates, the raw materials flowing in the blanking channel 311 are rapidly dispersed under the action of the generated centrifugal force. The centrifugal force causes the raw materials to be continuously pushed towards the outside of the blanking channel 311 when passing through the blanking channel 311 and slide downward along the wall surface of the blanking channel 311 at a relatively high speed, avoiding the stagnation and accumulation of raw materials in the blanking channel 311.

[0076] Since the raw materials are in a state of rapid movement and dispersion, it also promotes the uniform mixing of raw materials, ensuring the efficient progress of subsequent chemical reactions.

[0077] Through the synergistic effect of the inverted conical drainage plate 3, the positive conical baffle plate 5 and the surrounding structure 6, combined with the vibration and heating mechanisms, the present invention achieves the effect of efficient anti-hanging material. In this process, the inverted conical drainage plate 3 guides the raw materials to slide obliquely downward, avoiding direct impact on the inner wall. The surrounding structure 6 isolates the contact between the raw materials and the side wall of the reaction kettle, and the positive conical baffle plate 5 prevents the raw materials from splashing upward or contacting the top, ensuring that the raw materials flow along the predetermined path.

[0078] In addition, the vibration of the inverted conical drainage plate 3 and its cooperation with the metal bellows cause the raw materials to be continuously disturbed during the flow process, preventing stable adhesion and promoting rapid flow to the blanking channel 311. At the same time, the upper scraping rod 211 and the lower scraping rod 212 further remove the raw materials adhering to the surface, reduce the risk of accumulation, ensure smooth flow to the lower half reaction zone 13, effectively prevent the phenomenon of material hanging, and improve the production continuity and efficiency.

[0079] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
