Description

Technical Field

[0002] In the polycondensation reaction of water-reducing agents, the material transfer and regulation at different stages within the reactor are crucial for ensuring the orderly progress of the reaction. Traditional reactors often use simple valve structures to control the transfer of material from the upper reaction zone to the middle reaction zone. However, these traditional valves mostly achieve material flow through a single opening and closing mechanism, making it difficult to precisely control the material transfer speed and flow rate.

[0003] Traditional valves have low adjustment precision, making it difficult to achieve stable low-flow transmission when materials need to be slowly transferred to match the reaction progress. On the other hand, when large quantities of materials need to be transferred quickly, the valve channel may restrict the transmission efficiency, affecting the continuity of the reaction. Based on this, a temperature-controlled reactor suitable for the polycondensation reaction of water-reducing agents is proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Traditional valves have low adjustment precision, making it difficult to achieve stable low-flow transmission when slow material transfer is needed to match the reaction progress. Conversely, when rapid transfer of large quantities of material is required, valve channel limitations can lead to low transmission efficiency, affecting the continuity of the reaction. This embodiment provides a temperature-controlled reactor suitable for the polycondensation reaction of water-reducing agents. Please refer to... Figures 1-6 The embodiment provides a temperature-controlled reactor suitable for the polycondensation reaction of a water-reducing agent, including a reactor body 1, a connecting mechanism 2, a driving assembly 21 disposed in the upper section of the reactor body 1, a connecting assembly 22 disposed in the middle section of the reactor body 1, and a material feeding assembly 23 disposed in the lower section of the reactor body 1; the connecting assembly 22 includes a fixing block 221 fixedly installed on the outer wall of the middle section of the reactor body 1, and a rotating rod 222 rotatably connected to the inner wall of the middle section of the fixing block 221. A turntable 223 is fixedly connected to the outer end of the rotating rod 222. A drive gear 224 is fixedly connected to the outer wall of the middle section of the rotating rod 222. A rack plate 225 meshes with the outer wall of the drive gear 224. A fixing rod 227 is fixedly connected to the inner wall of the middle section of the reactor body 1. A limit slider 226 is fixedly connected to one end of the inner side of the fixing rod 227. Hinges 228 are hinged to both sides of the top of the rack plate 225. A connecting hinge frame 229 is hinged to the top of the hinge rod 228. A valve plate 2210 is fixedly connected to the top of the connecting hinge frame 229.

[0028] In this embodiment, after the raw materials are fully stirred and mixed in the upper section of the reactor body 1, they need to be transferred to the middle section of the reactor body 1 for further reaction via the connecting assembly 22. At this time, the operator rotates the turntable 223, which drives the rotating rod 222 to rotate on the inner wall of the middle section of the fixed block 221. The rotation of the rotating rod 222 drives the drive gear 224 to rotate, and the drive gear 224 meshes with the rack plate 225, so that the rack plate 225 moves linearly under the restriction of the limiting slider 226. The limiting slider 226 is fixed to the inner wall of the middle section of the reactor body 1 by the fixed rod 227, which can ensure that the rack plate 225 always moves along a fixed trajectory and will not deviate. The movement of the rack plate 225 drives the hinge rod 228 to swing, and the swing of the hinge rod 228 pushes the connecting hinge frame 229 to move up and down. The connecting hinge frame 229 then drives the valve plate 2210 to move. When the valve plate 2210 moves upward... When activated, the channel between the upper and middle sections of the reactor body 1 opens, allowing the pre-stirred raw materials to flow into the middle section under gravity. During the material transfer process, the operator can adjust the opening and closing degree of the valve plate 2210 by controlling the rotation angle of the turntable 223. If the turntable 223 rotates at a smaller angle, the drive gear 224 moves the rack plate 225 a shorter distance, the hinge rod 228 swings less, and the connecting hinge 229 raises the valve plate 2210 to a lower height, resulting in a smaller channel opening and a slower material transfer speed, suitable for stages where the reaction requires slow addition of raw materials. If the turntable 223 rotates at a larger angle, the valve plate 2210 rises to a higher height, the channel opens more fully, and the material transfer speed is faster, meeting the large demand for raw materials in the reaction. At the same time, the valve plate 2210 fits tightly against the inner wall of the middle section of the reactor body 1, effectively preventing backflow of raw materials when closed, ensuring the smooth progress of the reaction.

[0029] Furthermore, the rotating rod 222 is rotatably connected to the inner wall of the reactor body 1; the outer wall of the rack plate 225 is slidably connected to the inner wall of the limiting slider 226; the valve plate 2210 is sealed to the inner wall of the middle section of the reactor body 1; and one end of the connecting hinge 229 is hinged to the outer walls of the top two sides of the rack plate 225.

[0030] Furthermore, the limiting slider 226 is fixed to the inner wall of the middle section of the reactor body 1 by the fixing rod 227, which can ensure that the rack plate 225 always moves along a fixed trajectory and will not deviate; the movement of the rack plate 225 drives the hinge rod 228 to swing, and the swing of the hinge rod 228 pushes the connecting hinge frame 229 to move up and down, and the connecting hinge frame 229 drives the valve plate 2210 to move; when the valve plate 2210 moves upward, the channel between the upper section and the middle section of the reactor body 1 opens, and the raw materials that have been initially stirred will flow into the middle section under the action of gravity.

[0031] Example 2

[0032] Based on Embodiment 1, the drive assembly 21 includes a connecting feed pipe 211 that connects to the top of both sides of the reactor body 1. A fixing sealing plate 212 is fixedly installed on the top of the connecting feed pipe 211. A receiving cylinder 213 is fixedly connected to the inner wall of the middle section of the top of the reactor body 1. A drive motor 214 is fixedly installed at the bottom of the inner wall of the receiving cylinder 213. A rotating shaft 215 is fixedly connected to the bottom output end of the drive motor 214. A fixing cylinder 216 is fixedly connected to the outer wall of the lower section of the rotating shaft 215. The outer wall of the fixing cylinder 216 is fixedly connected to the... A fixed frame 217 is fixedly connected to the reactor body 1, and a limiting connecting rod 218 is fixedly connected to the inner wall of the fixed frame 217. The material discharge assembly 23 includes a material discharge hopper 231 fixedly connected to the inner wall of the middle section of the reactor body 1. A connecting rod 232 is fixedly connected to the inner wall of the lower section of the reactor body 1. A receiving side frame 233 is fixedly connected to the inner side of the connecting rod 232. A receiving filter box 234 is clamped and connected to the inner side of the receiving side frame 233. A material discharge pipe 235 is connected to the bottom of the reactor body 1. A fixed sealing plate 236 is fixedly installed at the bottom of the material discharge pipe 235.

[0033] In this embodiment, at the initial stage of the reaction, the drive assembly 21 starts working first; the operator opens the fixed sealing plate 212 at the top of the connecting feed pipe 211 and adds various raw materials required for the water-reducing agent polycondensation reaction into the reactor body 1 through the connecting feed pipe 211; after the raw materials are added, the fixed sealing plate 212 is closed again to prevent external impurities from entering the reactor body 1 and affecting the reaction; then, the drive motor 214 in the receiving cylinder 213 is started. When the drive motor 214 is working, its bottom output end drives the rotating shaft 215 to rotate at high speed; the rotating shaft 215... The rotation of the cylinder 216 causes the fixed cylinder 216 to rotate, which in turn causes the fixed frame 217 to rotate. The limiting rods 218 on the inner wall of the fixed frame 217 rotate with the rotation of the fixed frame 217. During the rotation, the limiting rods 218 will fully stir the raw materials in the upper section of the reactor body 1, so that the various raw materials can be mixed evenly. Moreover, the setting of the limiting rods 218 can also break the static state of the raw materials in the reactor, allowing the raw materials to come into more contact, preparing for the subsequent polycondensation reaction. During the stirring process, due to the equidistant distribution of the limiting rods 218... The fixed frame 217 is located on the inner wall, ensuring that the raw materials in each area of ​​the upper section of the reactor body 1 are uniformly stirred, avoiding uneven mixing in certain areas. After the raw materials enter the middle section of the reactor body 1, they will continue to undergo a condensation reaction. When the reaction proceeds to a certain extent and it is necessary to transfer the reaction products to the lower section, the feeding component 23 begins to function. The reaction products enter the feeding hopper 231 under gravity, and the shape design of the feeding hopper 231 guides the reaction products to flow towards the receiving filter box 234. The receiving filter box 234 is fixed to the reactor body 1 by the receiving side frame 233. In the lower section, the receiving side frame 233 is connected to the inner wall of the lower section of the reactor body 1 via the connecting rod 232, ensuring that the receiving filter box 234 remains stable during operation. After the reaction product enters the receiving filter box 234, the impurities therein will be filtered out. Because the receiving filter box 234 is equidistantly provided with filter holes, the pure reaction product can flow into the bottom of the lower section of the reactor body 1 through the filter holes. The filtered reaction product is finally discharged from the reactor through the discharge pipe 235. When discharge is not required, the fixed sealing plate 236 can prevent external impurities from entering the discharge pipe 235, ensuring the purity of the reaction product.

[0034] Furthermore, the bottom of the feeding pipe 211 is connected to the inner cavity of the upper section of the valve plate 2210, the limiting connecting rod 218 is fixedly connected to the inner wall of the fixing frame 217 at equal intervals, and the fixing frame 217 is circumferentially arranged on the outer wall of the fixing cylinder 216; the dropping hopper 231 is arranged on the top of the receiving filter box 234, and the receiving filter box 234 is provided with filter holes at equal intervals.

[0035] Furthermore, during the stirring process, since the limiting connecting rods 218 are equidistantly distributed on the inner wall of the fixed frame 217, it can ensure that the raw materials in each area of ​​the upper section of the reactor body 1 are uniformly stirred, avoiding uneven mixing of local raw materials; after the raw materials enter the middle section of the reactor body 1, they will continue to undergo condensation reaction; when the reaction proceeds to a certain extent and it is necessary to transfer the reaction products to the lower section, the feeding component 23 begins to play its role; the reaction products enter the feeding hopper 231 under the action of gravity, and the shape design of the feeding hopper 231 can guide the reaction products to flow towards the receiving filter box 234; the receiving filter box 234 is fixed to the lower section of the reactor body 1 by the receiving side frame 233, and the receiving side frame 233 is connected to the inner wall of the lower section of the reactor body 1 through the connecting rod 232, ensuring that the receiving filter box 234 remains stable during operation.

[0036] Working principle: In the initial stage of the reaction, the drive component 21 starts working first; the operator opens the fixed sealing plate 212 at the top of the connecting feed pipe 211 and adds various raw materials required for the water-reducing agent polycondensation reaction into the reactor body 1 through the connecting feed pipe 211; after the raw materials are added, the fixed sealing plate 212 is closed again to prevent external impurities from entering the reactor body 1 and affecting the reaction; then, the drive motor 214 in the receiving cylinder 213 is started. When the drive motor 214 is working, its bottom output end drives the rotating shaft 215 to rotate at high speed; the rotation of the rotating shaft 215 drives the fixed cylinder 216 to rotate together, and the fixed cylinder 216 in turn drives the fixed frame 2 17. As the fixed frame 217 rotates, the limiting rod 218 on the inner wall of the fixed frame 217 rotates as the fixed frame 217 rotates. During the rotation, the limiting rod 218 will fully stir the raw materials in the upper section of the reactor body 1, so that the various raw materials can be mixed evenly. Moreover, the setting of the limiting rod 218 can also break the static state of the raw materials in the reactor, allowing the raw materials to come into more full contact, preparing for the subsequent polycondensation reaction. During the stirring process, since the limiting rod 218 is equidistantly distributed on the inner wall of the fixed frame 217, it can ensure that the raw materials in each area of ​​the upper section of the reactor body 1 can be stirred evenly, avoiding the situation of uneven mixing of local raw materials.

[0037] After the raw materials are fully stirred and mixed in the upper section of the reactor body 1, they need to be transferred to the middle section of the reactor body 1 for further reaction via the connecting assembly 22. At this time, the operator rotates the turntable 223, which drives the rotating rod 222 to rotate on the inner wall of the middle section of the fixed block 221. The rotation of the rotating rod 222 drives the drive gear 224 to rotate, and the drive gear 224 meshes with the rack plate 225, so that the rack plate 225 moves linearly under the restriction of the limiting slider 226. The limiting slider 226 is fixed to the inner wall of the middle section of the reactor body 1 by the fixed rod 227, which can ensure that the rack plate 225 always moves along a fixed trajectory and will not deviate. The movement of the rack plate 225 drives the hinge rod 228 to swing, and the swing of the hinge rod 228 pushes the connecting hinge frame 229 to move up and down. The connecting hinge frame 229 then drives the valve plate 2210 to move. When the valve plate 2210 moves upward, the reverse... When the channel between the upper and middle sections of the reactor body 1 is opened, the raw materials, after initial stirring, will flow into the middle section under gravity. During the raw material transfer process, the operator can adjust the opening and closing degree of the valve plate 2210 by controlling the rotation angle of the turntable 223. If the rotation angle of the turntable 223 is small, the distance that the drive gear 224 drives the rack plate 225 to move is short, the swing amplitude of the hinge rod 228 is small, the height that the connecting hinge 229 drives the valve plate 2210 to rise is low, the degree of channel opening is small, and the raw material transfer speed is slow, which is suitable for the stage where the reaction requires the slow addition of raw materials. If the rotation angle of the turntable 223 is large, the valve plate 2210 rises to a higher height, the degree of channel opening is large, and the raw material transfer speed is fast, which can meet the large demand of the reaction for raw materials. At the same time, the valve plate 2210 is tightly attached to the inner wall of the middle section of the reactor body 1, which can effectively prevent the backflow of raw materials when closed, ensuring the smooth progress of the reaction.

[0038] After the raw materials enter the middle section of the reactor body 1, they will continue to undergo a polycondensation reaction. When the reaction proceeds to a certain extent and it is necessary to transfer the reaction products to the lower section, the feeding component 23 begins to function. The reaction products enter the feeding hopper 231 under the action of gravity. The shape design of the feeding hopper 231 can guide the reaction products to flow towards the receiving filter box 234. The receiving filter box 234 is fixed to the lower section of the reactor body 1 by the receiving side frame 233. The receiving side frame 233 is connected to the inner wall of the lower section of the reactor body 1 through the connecting rod 232 to ensure that the receiving filter box 234 remains stable during operation. After the reaction products enter the receiving filter box 234, the impurities will be filtered out. Because the receiving filter box 234 is equidistantly provided with filter holes, the pure reaction products can flow into the bottom of the lower section of the reactor body 1 through the filter holes. The filtered reaction products are finally discharged from the reactor through the feeding pipe 235. When it is not necessary to discharge, the fixed sealing plate 236 can prevent external impurities from entering the feeding pipe 235 and ensure the purity of the reaction products.

[0039] Throughout the reaction process, the components work together seamlessly. The drive component 21 provides power for the initial mixing of raw materials, the connecting component 22 precisely controls the transfer of raw materials, and the discharge component 23 is responsible for filtering and discharging the reaction products. Together, they ensure that the polycondensation reaction of the water-reducing agent can proceed efficiently and stably, producing high-quality water-reducing agent products.
