Description

Technical Field

[0001] This application relates to the field of acrylic resin production technology, and in particular to a high-efficiency stirring tank for acrylic resin production. Background Technology

[0002] Acrylic resin is an important chemical raw material widely used in coatings, adhesives, plastics, and other fields. In the production process of acrylic resin, the stirred tank is one of the key pieces of equipment, used to thoroughly mix the raw materials and promote the reaction. An existing patent (publication number: CN222490021U) discloses an acrylic resin production mixing tank. This utility model sets up a flow channel and a water spray nozzle inside the tank body, and then sets up a concentration tank. The concentration tank is equipped with a hot water chamber, a backup chamber, and a cold water chamber. During the polymerization reaction, the hot water in the hot water chamber exchanges heat with the tank body through the flow channel, thereby raising the temperature inside the tank body to assist the polymerization reaction. When the temperature inside the tank body is too high, cold water from the cold water chamber is poured into the flow channel to absorb the heat inside the tank body. The warm water that has completed the heat exchange is stored in the backup chamber. After processing, the raw materials are discharged, and the inner wall of the tank body is rinsed by hot water in the hot water chamber and the water spray nozzle. Then, the warm water in the backup chamber is sent to the hot water chamber to replenish it, reducing the energy consumption during heating. This setting can quickly cool down the raw materials inside the tank body and utilize the excess heat energy inside the tank body, reducing energy consumption.

[0003] While the apparatus in the aforementioned comparative documents can achieve the effect of cooling the raw materials, it cannot achieve more efficient and uniform dispersion by relying solely on a single stirring paddle. To address this issue, a high-efficiency stirring vessel for acrylic resin production is proposed. Utility Model Content

[0004] The purpose of this application is to provide a high-efficiency stirred tank for acrylic resin production, which has the advantages of efficient and uniform dispersion and solves the problems mentioned in the background art.

[0005] This application provides a high-efficiency mixing tank for acrylic resin production, which adopts the following technical solution: A high-efficiency mixing tank for acrylic resin production includes a mixing tank assembly, a temperature control assembly, and a cleaning assembly. The mixing tank assembly includes a mixing tank body and a first servo motor fixedly connected to the top of the mixing tank body. A first planar gear is fixedly connected to the output shaft end of the first servo motor. A hollow tube is rotatably sleeved on the top of the mixing tank body. A second planar gear that meshes with the first planar gear is fixedly connected to the outer surface of the hollow tube. Uniformly distributed water inlets are opened inside the hollow tube. A one-way valve is installed on the tube section of the hollow tube. Uniformly distributed stirring blades are fixedly connected to the outer surface of the hollow tube.

[0006] A second servo motor is fixedly connected to the bottom surface of the mixing vessel body. A rotating frame is fixedly connected to the output end of the second servo motor. The rotating frame has evenly distributed guide holes inside. A reverse spiral blade is fixedly connected to the inner bottom wall of the rotating frame. A shear bar is fixedly connected to the inner wall of the rotating frame.

[0007] By adopting the above technical solution, the first servo motor drives the first planar gear to rotate, which in turn drives the meshing second planar gear and hollow tube to rotate, so that the stirring blades can stir the raw materials laterally. At the same time, the second servo motor drives the rotating frame to rotate, and the reverse spiral blades inside can drive the raw materials to tumble upward. The shear bar forms a shearing effect on the raw materials, forming a composite stirring effect of vertical convection and multi-dimensional shearing. This solves the problem of uneven dispersion of the single stirring paddle in the existing device, significantly improves the uniformity and dispersion efficiency of the raw material mixing, and promotes the full progress of the polymerization reaction.

[0008] Preferably, the top of the mixing vessel body is connected to a feeding pipe, and the bottom of the mixing vessel body is connected to a discharging pipe.

[0009] By adopting the above technical solution, the feeding pipeline can accurately deliver various raw materials required for acrylic resin production into the mixing tank body, avoiding raw material spillage during the feeding process; the discharge pipeline can smoothly discharge the resin products after the reaction is completed. The combination of the two ensures the continuity of the production process, reduces the tediousness of manual operation, and improves production efficiency.

[0010] Preferably, the temperature control component includes an electromagnetic heating coil embedded inside the stirring vessel body, and a cooling jacket is fixedly connected to the outer surface of the stirring vessel body.

The combination of the two forms a two-way temperature control regulation. Compared with the heat exchange method of the existing device, the temperature control response is faster and can flexibly adapt to the temperature requirements of different stages in the reaction process, ensuring the stable progress of the reaction.

[0012] Preferably, a heat insulation plate is fixedly connected to the outer surface of the cooling jacket, and a liquid storage tank is fixedly connected to the outer surface of the heat insulation plate.

[0013] By adopting the above technical solution, the liquid storage tank can store liquid for cooling, continuously provide cooling medium for the cooling jacket, ensure the stability of the cooling function, and the heat insulation plate can reduce the heat exchange between the liquid storage tank and the cooling jacket, optimize the storage state of the coolant inside the liquid storage tank, and further optimize the temperature control effect.

The two first liquid pumps are respectively connected to a delivery pipe and a suction pipe. One end of the delivery pipe is connected to the top of the cooling jacket, and one end of the suction pipe is connected to the bottom of the cooling jacket.

[0015] By adopting the above technical solution, the first liquid pump delivers the coolant from the storage tank to the top of the cooling jacket through the liquid delivery pipe, and draws the coolant from the bottom of the cooling jacket back to the storage tank through the liquid suction pipe, forming a circulation of coolant. This makes the cooling jacket cool the stirring vessel body more evenly, avoids excessive local temperature, and improves the accuracy of temperature control.

[0016] Preferably, a temperature sensor is installed on the inner bottom wall of the stirring vessel body, and a liquid replenishment pipe and a liquid drain pipe are connected to the upper and lower ends of the liquid storage tank.

[0017] By adopting the above technical solution, the temperature sensor can monitor the raw material temperature in the stirred tank in real time, which facilitates timely adjustment of heating or cooling operations; the replenishment pipe and the drain pipe facilitate the replenishment of coolant to the storage tank or the discharge of waste liquid, ensuring the continuous and effective operation of the cooling system and ensuring that the reaction temperature is always within a suitable range.

[0018] Preferably, the cleaning assembly includes a second liquid pump installed at the top of the liquid storage tank, the output end of the second liquid pump is connected to a cleaning tube, the top end of the hollow tube is rotatably sleeved inside the cleaning tube, and the cleaning tube is connected to the hollow tube.

[0019] By adopting the above technical solution, the second liquid pump sends the cleaning liquid into the hollow tube through the cleaning pipe. The cleaning liquid is sprayed out through the water outlet. At the same time, the hollow tube rotates with the stirring process, so that the cleaning liquid can evenly cover the inner wall of the stirring vessel and the stirring components. With the help of the one-way valve, the raw materials are prevented from backflowing, the cleaning efficiency is improved, and the residual raw materials are avoided from affecting the quality of the subsequent reaction products.

[0020] Preferably, a main controller is fixedly connected to the outer surface of the liquid storage tank, and the electrical components inside the stirring vessel assembly, temperature control assembly, and cleaning assembly are all electrically connected to the main controller.

[0021] By adopting the above technical solution, the main controller centrally controls the electrical components of the stirring vessel assembly, temperature control assembly, and cleaning assembly. It can coordinate operations such as stirring speed, temperature control start / stop, and cleaning timing to achieve automated production, reduce manual intervention, improve operational convenience and production stability, and ensure the consistency of efficient stirring and reaction effects.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This high-efficiency mixing vessel for acrylic resin production utilizes a first servo motor in the mixing vessel assembly to drive the mixing blades for horizontal stirring, while a second servo motor drives the rotating frame, reverse spiral blades, and shear bars to form a composite stirring system. This solves the problem of uneven dispersion caused by a single mixing blade. The feeding and discharging pipelines ensure continuous production. The temperature control assembly features an electromagnetic heating coil and a cooling jacket for bidirectional temperature control, a heat insulation plate to reduce heat loss, a coolant circulation system between the storage tank and the first liquid pump, and a temperature sensor to ensure accurate temperature control.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A high-efficiency stirred tank for acrylic resin production, referring to... Figure 1 , Figure 2 and Figure 5The system includes a mixing vessel assembly 1, a temperature control assembly 2, and a cleaning assembly 3. The mixing vessel assembly 1 includes a mixing vessel body 101 and a first servo motor 102 fixedly connected to the top of the mixing vessel body 101. A first planar gear 103 is fixedly connected to the output shaft end of the first servo motor 102. A hollow tube 104 is rotatably sleeved on the top of the mixing vessel body 101. A second planar gear 105 that meshes with the first planar gear 103 is fixedly connected to the outer surface of the hollow tube 104. The hollow tube 104 has evenly distributed water inlets 106 inside. A one-way valve 107 is installed on the tube section of the hollow tube 104. Evenly distributed stirring blades 108 are fixedly connected to the outer surface of the hollow tube 104.

[0027] Reference Figure 2 , Figure 4 and Figure 5 A second servo motor 115 is fixedly connected to the bottom surface of the mixing tank body 101. A rotating frame 109 is fixedly connected to the output end of the second servo motor 115. The rotating frame 109 has evenly distributed guide holes 110 inside. A reverse spiral blade 111 is fixedly connected to the inner bottom wall of the rotating frame 109. A shear bar 112 is fixedly connected to the inner wall of the rotating frame 109. A feeding pipe 113 is connected to the top of the mixing tank body 101, and a discharge pipe 114 is connected to the bottom of the mixing tank body 101. The feeding pipe 113 facilitates the precise feeding of various raw materials required for acrylic resin production into the mixing tank body 101, avoiding material spillage during the feeding process. The discharge pipe 114 can smoothly discharge the resin products after the reaction is completed. The two work together to ensure the continuity of the production process, reduce the tediousness of manual operation, and improve production efficiency.

[0028] Example 2: A high-efficiency stirred tank for acrylic resin production, referring to... Figure 2 , Figure 3 and Figure 5Based on the same concept as Embodiment 1 above, this embodiment proposes that the temperature control component 2 includes an electromagnetic heating coil 201 embedded inside the stirred tank body 101, and a cooling jacket 202 is fixedly connected to the outer surface of the stirred tank body 101. The electromagnetic heating coil 201 can quickly heat the raw materials inside the stirred tank body 101 to meet the temperature conditions required for the polymerization reaction; the cooling jacket 202 can cool down the raw materials when the temperature is too high. The combination of the two forms a bidirectional temperature control regulation. Compared with the heat exchange method of the existing device, the temperature control response is faster and more flexible. To adapt to the temperature requirements at different stages of the reaction and ensure stable reaction, a heat insulation plate 203 is fixedly connected to the outer surface of the cooling jacket 202. A liquid storage tank 204 is fixedly connected to the outer surface of the heat insulation plate 203. The liquid storage tank 204 stores liquid for cooling, continuously providing a cooling medium to the cooling jacket 202 and ensuring stable cooling function. The heat insulation plate 203 reduces heat exchange between the liquid storage tank 204 and the cooling jacket 202, optimizes the storage state of the coolant inside the liquid storage tank 204, and further optimizes the temperature control effect. The upper and lower ends of the liquid storage tank 204... Each cooling jacket 202 is equipped with a first liquid pump 205. The two first liquid pumps 205 are internally connected to a delivery pipe 206 and a suction pipe 207, respectively. One end of the delivery pipe 206 is connected to the top of the cooling jacket 202, and one end of the suction pipe 207 is connected to the bottom of the cooling jacket 202. The first liquid pump 205 delivers coolant from the storage tank 204 to the top of the cooling jacket 202 through the delivery pipe 206, and draws coolant from the bottom of the cooling jacket 202 back to the storage tank 204 through the suction pipe 207, forming a circulating flow of coolant. This allows the cooling jacket 202 to circulate coolant over the stirring vessel body 10. The cooling is more uniform, avoiding excessive local temperature and improving the accuracy of temperature control. A temperature sensor 208 is installed on the inner bottom wall of the stirred tank body 101. The upper and lower ends of the liquid storage tank 204 are connected to the liquid replenishment pipe 209 and the liquid drain pipe 210. The temperature sensor 208 can monitor the raw material temperature in the stirred tank body 101 in real time, which facilitates timely adjustment of heating or cooling operations. The liquid replenishment pipe 209 and the liquid drain pipe 210 facilitate the replenishment of coolant to the liquid storage tank 204 or the discharge of waste liquid, ensuring the continuous and effective operation of the cooling system and ensuring that the reaction temperature is always within a suitable range.

[0029] Reference Figure 1 , Figure 2 and Figure 3The cleaning assembly 3 includes a second liquid pump 301 installed at the top of the storage tank 204. The output end of the second liquid pump 301 is connected to a cleaning pipe 302. The top end of the hollow tube 104 is rotatably sleeved inside the cleaning pipe 302. The cleaning pipe 302 is connected to the hollow tube 104. The second liquid pump 301 sends the cleaning liquid into the hollow tube 104 through the cleaning pipe 302. The cleaning liquid is sprayed out through the water inlet 106. At the same time, the hollow tube 104 rotates during the stirring process, so that the cleaning liquid can evenly cover the inner wall of the stirring vessel body 101 and the stirring components. With the help of the one-way valve 107, the raw materials are prevented from overflowing. The system improves cleaning efficiency and prevents residual raw materials from affecting the quality of subsequent reaction products. The outer surface of the storage tank 204 is fixedly connected to the main controller 4. The electrical components inside the stirring vessel assembly 1, temperature control assembly 2, and cleaning assembly 3 are all electrically connected to the main controller 4. The main controller 4 centrally controls the electrical components of the stirring vessel assembly 1, temperature control assembly 2, and cleaning assembly 3, and can coordinate operations such as stirring speed, temperature control start and stop, and cleaning timing to achieve automated production, reduce manual intervention, improve operational convenience and production stability, and ensure the consistency of efficient stirring and reaction results.

[0030] The implementation principle of this application embodiment is as follows: After the main controller 4 is started, the raw materials required for acrylic resin production are fed into the mixing tank body 101 through the feeding pipe 113. The first servo motor 102 drives the first planar gear 103 to rotate, and the second planar gear 105 meshing with the first planar gear 103 drives the hollow tube 104 to rotate, so that the stirring blades 108 on the outer surface of the hollow tube 104 stir the raw materials laterally. At the same time, the second servo motor 115 drives the rotating frame 109 to rotate, and the reverse spiral blades 111 in the rotating frame 109 drive the raw materials to turn upward. The shear bars 112 on the inner wall form a shearing action on the raw materials. Combined with the diversion effect of the guide hole 110, a composite stirring of vertical convection and multi-dimensional shearing is formed, which promotes uniform mixing and reaction of the raw materials. During the reaction, the electromagnetic heating coil 201 embedded in the mixing tank body 101 can quickly heat the raw materials. When the temperature sensor 208 detects the temperature inside the tank, When the temperature is too high, the main controller 4 starts the first liquid pump 205, which sends the coolant in the storage tank 204 into the cooling jacket 202 through the delivery pipe 206. After absorbing heat, the coolant flows back to the storage tank 204 through the suction pipe 207 to form a circulation. The heat insulation plate 203 reduces the heat exchange between the storage tank 204 and the cooling jacket 202. If the coolant is insufficient or needs to be replaced, it can be replenished through the replenishment pipe 209 or discharged through the drain pipe 210. After the reaction is completed, the product is discharged through the discharge pipe 114. The main controller 4 starts the cleaning component 3, and the second liquid pump 301 sends the liquid in the storage tank 204 into the hollow tube 104 through the cleaning pipe 302. The cleaning liquid is sprayed out through the water outlet 106 and evenly covers the inner wall of the stirring vessel body 101 and the stirring components as the hollow tube 104 rotates, achieving the effect of rational utilization of resources. The one-way valve 107 prevents the raw material from backflowing. After cleaning is completed, the main controller 4 is turned off. The whole process is automated and linked to ensure efficient production.
