Description

Technical Field

[0001] The present invention relates to the technical field of chemical preparation devices, and specifically to a preparation device for sodium methallyl sulfonate particles. Background Art

[0002] Sodium methallyl sulfonate (SMAS) is an important functional monomer, which is widely used in fields such as water treatment agents, polymer dispersants, textile printing and dyeing aids, etc. The physical properties of its particle morphology (such as particle size distribution, fluidity, solubility, etc.) have a significant impact on the performance of downstream applications. Currently, the industrial processes for preparing sodium methallyl sulfonate particles mainly include methods such as solution polymerization, spray drying, and crystallization precipitation.

[0003] After retrieval, it is found that the prior art publication number is CN221108234U, which discloses a sodium methallyl sulfonate production device, relating to the technical field of chemical preparation, including a tank body and a suction mechanism arranged on one side of the tank body. A preparation tank is arranged inside the tank body, and there is a sandwich layer for filling coolant between the preparation tank and the tank body. This utility model solves the problem that the existing sodium methallyl sulfonate production device does not handle the waste gas during the production process, resulting in the continuous accumulation of waste gas in the reaction tank during the reaction process, and it is easy to cause waste gas leakage during discharging. Through the passive opening of the pressure relief component, while releasing the air pressure inside the preparation tank, the locking component is driven to lock the pressure relief component. At the same time, the negative pressure component generates a negative pressure so that after the air pressure is released, the remaining waste gas inside the preparation tank can continue to be extracted. The extracted waste gas and clear water are sent into the sandwich layer together, and the hydrogen sulfide and water combine to form dilute sulfuric acid to cool and control the temperature of the preparation tank.

[0004] Therefore, based on the above retrieval and combined with the existing technology, during the mixing process of the sodium methallyl sulfonate precursor and the additive in the existing device, there is generally a problem of uneven mixing leading to incomplete local reactions. At the same time, the material is prone to caking, and subsequent crushing processes have to be added. When the produced sodium methallyl sulfonate particles are stored in a pile, due to the difficulty of dissipating the heat accumulated between the particles, the local temperature will be too high, which not only affects the fluidity of the product, but also causes thermal damage to the material, ultimately reducing the product purity and key physical performance indicators. For this reason, this application proposes a preparation device for sodium methallyl sulfonate particles. Summary of the Invention

The power transmission is realized through the linkage design of the central pipe and the driving rod to ensure the stable operation of the scroll fan, and the accurate alignment of the output end of the material pipe realizes the efficient conveying of the material.

[0009] As a further scheme of the present invention, a plurality of stirring and dispersing rods are fixedly installed on the outer surface of the driving rod, a plurality of material dispersing holes are opened on the outer surface of the central pipe, and the stirring and dispersing rods are located above the material dispersing holes. An isolation plate is fixedly installed inside the mixing cylinder, and the isolation plate is located below the central cylinder.

One end of the grinding plate close to the isolation plate is fixedly connected with an output pipe, and the output pipe corresponds to the driving rod.

This design can not only quickly reduce the temperature of the material but also evenly disperse the particles to the pressure relief holes through the air flow guidance, effectively preventing heat accumulation and ensuring the stable product quality. At the same time, the entire cooling process is completely automatically regulated by the temperature change. Brief Description of the Drawings

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1: Please refer to Figure 1 ,Figure 2 , a preparation device for sodium methallyl sulfonate particles, comprising a reaction kettle 1. A sealing cover 3 is fixedly installed at the upper end of the reaction kettle 1 through bolts. At one end of the sealing cover 3 away from the reaction kettle 1, a heating chamber 4 for heating sodium methallyl sulfonate is fixedly installed through bolts. On the left side of the reaction kettle 1, there is a material box 6 for loading materials, which is used to add a catalyst to the reaction system. The bottom end of the material box 6 is fixedly connected with a material pipe 5, and the output end of the material pipe 5 is connected to the heating chamber 4. On the right side of the reaction kettle 1, there is a hot air furnace 7. The output end of the hot air furnace 7 is fixedly connected with a gas guide pipe 2, and the output end of the gas guide pipe 2 is fixedly connected with the input end of the heating chamber 4. The hot air furnace 7 outputs high-speed hot air flow to dry the sodium methallyl sulfonate. Its working principle adopts existing mature technologies and will not be elaborated here. Inside the reaction kettle 1, a mixing cylinder 102 is fixedly installed. At the upper end of the mixing cylinder 102, a central cylinder 101 is fixedly installed through bolts. The central cylinder 101 and the mixing cylinder 102 are on the same axis. Inside the mixing cylinder 102 and the central cylinder 101, there is a mixing device for promoting the synthesis of sodium methallyl sulfonate. Inside the reaction kettle 1, there is a discharge pipe 201, which is located below the mixing cylinder 102. A cooling device for preventing the sodium methallyl sulfonate from overheating is arranged between the discharge pipe 201 and the reaction kettle 1.

[0020] As Figure 2 , Figure 3 shown, inside the heating chamber 4, a vortex fan 103 is rotatably installed. The output end of the gas guide pipe 2 corresponds to the side end of the vortex fan 103. The high-speed hot air flow blown out from the hot air furnace 7 is blown out through the gas guide pipe 2 and drives the vortex fan 103 to rotate. Both the gas guide pipe 2 and the material pipe 5 are made of metal. The output end of the material pipe 5 is opposite to the center position of the vortex fan 103. At the inner bottom end of the heating chamber 4, a plurality of discharge holes 104 are opened. The discharge holes 104 are arranged in a ring shape. When the vortex fan 103 rotates, hot air flow is blown out in the direction of the discharge holes 104.

[0021] Please refer to Figure 3 - Figure 7 , the mixing device includes a central pipe 301. The central pipe 301 is fixedly connected to the inner bottom end of the central cylinder 101. Inside the central pipe 301, a driving rod 302 is rotatably installed. One end of the driving rod 302 away from the central pipe 301 is fixedly connected to the vortex fan 103, and the driving rod 302 corresponds to the output end of the material pipe 5. At one end of the driving rod 302 close to the vortex fan 103, a plurality of diversion holes 306 are opened. The diversion holes 306 are located inside the central pipe 301. The diversion holes 306 are arranged in a ring shape and are used to spray the sodium methallyl sulfonate flowing here in all directions under the action of the diversion holes 306; A plurality of stirring rods 305 are fixedly installed on the outer surface of the driving rod 302. A plurality of material scattering holes 309 are formed on the outer surface of the central tube 301, and the stirring rods 305 are located above the material scattering holes 309. Specifically, when the driving rod 302 rotates, it drives the stirring rods 305 to rotate. A blade is fixedly welded to the end of the stirring rod 305 away from the driving rod 302. The blade maintains a certain inclination angle, so that the sodium methallyl sulfonate flowing here is scattered by the stirring rod 305 and then flows out from the material scattering holes 309 on the outer surface of the central tube 301.

[0022] An isolation plate 303 is fixedly installed at the inner end of the mixing cylinder 102. The isolation plate 303 is spiral. The isolation plate 303 is located below the central cylinder 101. A grinding plate 304 is rotatably installed at the inner bottom end of the mixing cylinder 102. The grinding plate 304 is located below the isolation plate 303. One end of the grinding plate 304 close to the isolation plate 303 is fixedly connected with an output pipe 307. The output pipe 307 corresponds to the driving rod 302. A plurality of rectangular holes are formed at the upper end of the mixing cylinder 102. The rectangular holes are arranged in a ring. The sodium methallyl sulfonate flowing out from the material scattering holes 309 on the outer surface of the central tube 301 is under the rotation action of the vortex fan 103 and moves into the interior of the mixing cylinder 102 along with the direction of the air flow. A plurality of through holes are formed on the outer surface of the central cylinder 101. The through holes are arranged in a ring; Specifically, the output pipe 307 and the bottom end of the driving rod 302 are connected by a plurality of passive arc plates 308. The passive arc plates 308 are arranged in a ring, and the outer surface of the passive arc plates 308 is twisted. When rotating, the twisted structure generates an attraction force. The sodium methallyl sulfonate is guided by the spiral isolation plate 303 to the upper part of the grinding plate 304, forms a circular motion with the rotation of the grinding plate 304 and the passive arc plates 308, and flows towards the output pipe 307 under the adsorption action when the passive arc plates 308 rotate. A plurality of diversion grooves are formed at the bottom end of the driving rod 302, and the groove openings are facing the passive arc plates 308. The residual sodium methallyl sulfonate flows out through the diversion grooves between the driving rod 302 and the central tube 301. Both the passive arc plates 308 and the output pipe 307 are made of metal. A catalyst injection pipe is arranged on the side wall of the mixing cylinder 102 for adding a catalyst to the reaction system; More specifically, a plurality of annular blades are fixedly installed at the upper end of the grinding plate 304. Then when the grinding plate 304 rotates, it drives the annular blades to rotate. The sodium methallyl sulfonate contacts the annular blades during the flow process on the grinding plate 304, so that the sodium methallyl sulfonate particles can be further ground to prevent caking during the mixing process. At the same time, under the rotation action of the grinding plate 304, it is more uniform during the mixing process. The sodium methallyl sulfonate particles receive the hot air action of the vortex fan 103 in the chambers of the isolation plate 303 and the grinding plate 304 to achieve deep drying.

[0023] Example 2: Please refer to Figure 1 、 Figure 8 -Figure 10 , a preparation device for sodium methallyl sulfonate particles. Based on Example 1, the cooling device includes a cooling pipe 202. The cooling pipe 202 is fixedly connected to the outer surface of the discharge pipe 201. The upper end of the discharge pipe 201 is rotatably connected to the bottom end of the grinding plate 304, and the discharge pipe 201 is communicated with the output pipe 307. The outer surface of the cooling pipe 202 is fixedly connected to the inner end of the reaction kettle 1. A conduction pipe 208 for conveying air is arranged through the inner end of the cooling pipe 202. A filter element is arranged inside the conduction pipe 208 for filtering the air entering the inside of the reaction kettle 1 from the outside. One end of the conduction pipe 208 away from the discharge pipe 201 is fixedly connected with a pull ring 203 which is convenient to hold; A heating pipe 204 is arranged through the inside of the discharge pipe 201 for detecting the temperature inside the discharge pipe 201. The heating pipe 204 is in an "L" shape. An unlocking rod 210 is slidably installed at the inner end of the heating pipe 204. The unlocking rod 210 corresponds to the pull ring 203. A lifting plate 211 is slidably installed on the outer surface of the cooling pipe 202, and the lifting plate 211 is fixedly connected with the unlocking rod 210. Specifically, a bimetallic spiral sheet is arranged at the inner end of the heating pipe 204. The bottom end of the bimetallic spiral sheet is in contact with the outer surface of the unlocking rod 210. The bimetallic spiral sheet is formed by overlapping two metal sheets with different coefficients of thermal expansion. After being heated, due to the different coefficients of thermal expansion of the two different materials of metal, the bimetallic spiral sheet begins to twist and pushes the unlocking rod 210 in the direction of the pull ring 203.

[0024] A stabilizing plate 205 is fixedly installed on the outer surface of the discharge pipe 201 through a clamp, and the stabilizing plate 205 is parallel to the heating pipe 204. An air outlet 209 is opened at one end of the cooling pipe 202 close to the discharge pipe 201. The diameter of the air outlet 209 is smaller than the diameter of the cooling pipe 202, so that the air flowing out will be compressed and then quickly spread out. Under the action of adiabatic expansion, the temperature of the air will quickly decrease, thereby achieving the effect of cooling the sodium methallyl sulfonate particles. A locking block 207 is arranged through the outer surface of the cooling pipe 202. The locking block 207 is connected with the stabilizing plate 205 through a return spring 206. Under the action of the elastic force of the return spring 206, the locking block 207 can always maintain a downward moving force; A sliding hole is opened on the outer surface of the locking block 207. The lifting plate 211 is arranged through the inside of the sliding hole. The lifting plate 211 is arc-shaped. After the lifting plate 211 moves in the direction away from the discharge pipe 201, the locking block 207 slides along the outer surface of the arc-shaped lifting plate 211, so that the locking block 207 moves upward and compresses the return spring 206; A conducting plug 212 is fixedly welded to one end of the conducting tube 208 close to the discharge pipe 201. The diameter of the conducting plug 212 is smaller than the diameter of the conducting tube 208. The locking block 207 corresponds to the conducting plug 212. Under the elastic force of the return spring 206, the bottom end of the locking block 207 is in contact with the outer surface of the conducting plug 212. At this time, the conducting tube 208 cannot move toward the direction of the discharge pipe 201 due to the restriction of the locking block 207.

[0025] like Figure 9 , Figure 10 As shown, a ventilation groove 213 is provided on the outer surface of the conducting plug 212, and the ventilation groove 213 is connected to the interior of the conducting pipe 208. A sealing ring 214 is fixedly installed on the inner end of the cooling pipe 202, and the sealing ring 214 is located on the right side of the passive arc plate 308. Specifically, a sealing rubber ring is fixedly installed on the inner end of the sealing ring 214, and fits with the outer surface of the conducting plug 212 to increase the air tightness. When the conducting plug 212 moves in the direction of the discharge pipe 201, the ventilation groove 213 will pass over the sealing ring 214. At this time, air can enter from the conducting pipe 208, pass through the ventilation groove 213, and be ejected from the air outlet 209. A pressure relief hole 310 is provided on the outer surface of the discharge pipe 201, and the pressure relief hole 310 corresponds to the air outlet 209.

[0026] A funnel is fixedly installed at the bottom of the reaction kettle 1 by bolts. The funnel corresponds to the discharge pipe 201 and is used to collect the dried sodium methacrylate sulfonate particles.

[0027] The working principle of the present invention is: When in use, the sodium methacrylate sulfonate precursor to be reacted is poured into the material box 6, and then the hot blast furnace 7 is started. The hot blast furnace 7 outputs a high-speed and high-temperature airflow, which enters the interior of the heating bin 4 along the air guide pipe 2, and drives the turbofan 103 inside the heating bin 4 to rotate. As the turbofan 103 rotates at a high speed, the pressure inside the heating bin 4 decreases. At this time, the sodium methacrylate sulfonate particles inside the material box 6 enter the interior of the heating bin 4 along the material pipe 5 under the action of pressure; The sodium methacrylate sulfonate particles enter the diverter hole 306 at the upper end of the driving rod 302, and are scattered and splashed under the action of high-speed rotation. They enter the interior of the central tube 301 along with the airflow, and are further dispersed by the rotation of the stirring rod 305 to break up the sodium methacrylate sulfonate particles. Then, the sodium methacrylate sulfonate particles are ejected through the scattering holes 309 on the outer surface of the central tube 301. The sodium methacrylate sulfonate particles ejected from the scattering holes 309 are quickly moved to the upper end of the isolation plate 303 under the action of the airflow generated by the rotation of the turbofan 103. When the driving rod 302 rotates, it drives the output pipe 307 to rotate through the passive arc plate 308. When the driving rod 302 drives the output pipe 307 to rotate through the passive arc plate 308, an attractive force is generated when the passive arc plate 308 rotates. At this time, the sodium methallyl sulfonate particles located above the partition plate 303 enter above the grinding plate 304 along the curvature of the outer surface of the partition plate 303 and rotate with the grinding plate 304 to perform a circular motion. At the same time, under the rotation of the passive arc plate 308, they move in the direction of the output pipe 307, enabling them to further mix the sodium methallyl sulfonate precursor with the catalyst. At the same time, it can also prevent caking during the mixing process. Then, it is mixed with the catalyst and reacts. Subsequently, it is ejected from the bottom end of the discharge pipe 201 and falls into the funnel; When the temperature inside the discharge pipe 201 is relatively high, the bimetallic spiral in the heat receiving pipe 204 is distorted under the action of high temperature and pushes the unlocking rod 210. The unlocking rod 210 moves in the direction close to the pull ring 203. The unlocking rod 210 drives the lifting plate 211 to move, causing the locking block 207 to move upward and compress the return spring 206. Since the air flow rate inside the discharge pipe 201 is relatively fast, the internal air pressure is relatively small. At this time, the conduction pipe 208 pushes the conduction plug 212 in the direction of the discharge pipe 201 under the action of air pressure. At this time, air flows from the ventilation groove 213 to the air outlet 209 and is ejected from it to cool the sodium methallyl sulfonate particles. The air flow blown out from the air outlet 209 blows the sodium methallyl sulfonate particles towards the pressure relief hole 310. When the cooled sodium methallyl sulfonate particles fall into the funnel, it further prevents the accumulation of high-temperature sodium methallyl sulfonate particles, resulting in the inability to dissipate heat in a timely manner, thereby affecting the product quality.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
