Description

Technical Field

[0001] This utility model relates to the field of polyester resin synthesis cooling technology, specifically to a rapid cooling device for polyester resin synthesis. Background Technology

[0002] Polyester resin is a general term for high molecular weight compounds formed by the condensation polymerization of diols, diacids, or polyols and polyacids. During the synthesis process, polyester resin undergoes a reaction and curing, which generates a certain amount of heat. To avoid excessive heat from adversely affecting the synthesis equipment and products, a cooling device is required.

[0003] For example, the national authorized patent announcement number CN222670439U discloses a rapid cooling device for polyester resin synthesis, including a shell. A water storage tank is fixedly installed on the right side of the shell via a pipe. A water pump is connected to the right side pipe of the water storage tank. A cooler is fixedly installed on the back of the water storage tank and connected to the water pump pipe. An inner liner is fixedly sleeved on the inner wall of the shell, and a cooling water pipe located inside the shell is fixedly sleeved on the outer wall of the inner liner. This utility model, through the cooperation between the water storage tank, filter plate, cooling water pipe, and inner liner, utilizes the filter plate to filter impurities in the water in the water storage tank, effectively solving the problem of impurity accumulation in the cooling chamber in the aforementioned disclosed technology. By using a filter plate to separate water and impurities in the water storage tank, it avoids impurities flowing with the water flow into the interior of the cooling water pipe and accumulating there, thereby ensuring the cooling effect of the circulating cooling water in the cooling water pipe on the inner end.

[0004] However, the aforementioned rapid cooling device for polyester resin synthesis has a relatively simple cooling method, resulting in poor cooling effect. Temperature gradients are easily formed inside the material, leading to slow cooling and uneven local cooling, which affects the quality of polyester resin synthesis. In addition, the stirring efficiency is low and the anti-sticking effect is limited. Utility Model Content

Figures 1-11As shown, it includes: a base plate 1; a polyester resin synthesis tank 2 is mounted on the upper surface of the base plate 1; an inner liner 204 is mounted inside the polyester resin synthesis tank 2; a cooling component 5 is mounted in the inner liner 204; a water storage tank 3 is mounted at the other end of the upper surface of the base plate 1; a circulation tank 302 is connected to the lower surface of the water storage tank 3; the input end of the cooling component 5 is connected to the water storage tank 3; and the output end is connected to the circulation tank 302. A top cover 4 is attached to the upper surface of the polyester resin synthesis tank 2; fixing plates 201 are fixedly installed on both sides of the outer surface of the top cover 4 and the polyester resin synthesis tank 2. Electric push rods 202 are installed on the upper surface of the fixing plates 201 installed on both sides of the polyester resin synthesis tank 2. The piston rod of the electric push rod 202 is connected to the lower surface of the fixing plates 201 installed on both sides of the top cover 4. The upper surface of the top cover 4 is equipped with a drive motor 401, and the lower surface of the top cover 4 is bonded with a sealing ring 406. The lower surface of the polyester resin synthesis tank 2 is connected to a discharge pipe 203. The lower surface of the circulation tank 302 is equipped with a drain outlet 304. The middle section of the drain outlet 304 is equipped with a switch valve 6. The outer surface of the inner liner 204 is equipped with a spiral groove 205. The output shaft of the drive motor 401 is connected to a connecting block 402. The lower surfaces of the connecting block 402 are respectively equipped with stirring plates 403. The two stirring plates 403 are tilted at opposite angles. Linkage plates 404 are installed on both sides of the two stirring plates 403. Scrapers 405 are fixedly connected to one side of the multiple linkage plates 404. The installation angle of the scrapers 405 is the same as that of the stirring plates 403, and the surface is bonded with a polytetrafluoroethylene anti-stick layer. The upper surface of the water storage tank 3 is provided with an inlet 301, and a first filter screen 305 is provided inside the inlet 301. A hole is provided on one side of the circulation tank 302. Sliding holes 307 are provided on both sides of the inner wall of the circulation tank 302. A filter plate 308 is slidably inserted into the hole, and a second filter screen 311 is provided inside the filter plate 308. Sliding blocks 312 are fixedly installed on both sides of the filter plate 308, and the sliding blocks 312 are slidably installed in the sliding holes 307. The filter plate 308 is located at the connection between the circulation tank 302 and the water storage tank 3. A bonding plate 309 is fixedly connected to the other end of the filter plate 308. The bonding plate 309 is bonded to one side of the circulation tank 302 to cover the hole. Multiple sealing strips 310 are adhered to the surface of the bonding plate 309. Both the bonding plate 309 and one side of the circulation tank 302 have the same threaded holes, and bolts are threaded into the threaded holes. A pull-out plate 303 is fixedly connected to the other end of the bonding plate 309.

[0023] Through the design of the polyester resin synthesis tank 2, cooling component 5, and spiral groove 205, cooling water is added through the inlet 301 on the upper surface of the water storage tank 3. The first filter screen 305 inside the inlet 301 filters impurities in the new water to prevent clogging of subsequent pipelines. Then, the cooling component 5 cools the inner tank 204. Afterward, the electric push rod 202 drives the top cover 4 to rise. After adding the materials required for polyester resin synthesis into the inner tank 204, the electric push rod 202 retracts, and the top cover 4 descends to fit against the upper surface of the polyester resin synthesis tank 2. The sealing ring 406 on the lower surface of the top cover 4 achieves a seal to prevent material leakage or the entry of external impurities. The drive motor 401 is started, and its output shaft drives the connecting block 402 to rotate, thereby... The stirring plates 403 at both ends rotate, and the opposing tilt of the stirring plates 403 can fully mix the materials, reduce local overheating caused by local material stagnation, and ensure that the overall temperature of the material drops evenly. The scrapers 405 on both sides of the stirring plates 403 rotate synchronously. Since the tilt angle of the scrapers 405 is the same as that of the stirring plates 403, the scrapers 405 form a better contact and scraping angle with the inner tank 204 wall, easily peeling off the materials sticking to the wall. The polytetrafluoroethylene anti-stick layer on the surface can prevent polyester resin from sticking to the inner tank 204 wall due to high temperature. After that, the cooled circulating water flows back into the circulation tank 302. The filter plate 308, which is slidably inserted between the circulation tank 302 and the water storage tank 3, can effectively filter impurities in the water and reduce pipeline blockage.

[0024] It is worth noting that the filter plate 308 is engaged with the sliding hole 307 of the circulation box 302 via the sliding block 312, allowing it to be pulled out flexibly. When the second filter screen 311 is clogged, the bolts on the bonding plate 309 can be unscrewed, and the filter plate 308 can be pulled out via the pull plate 303 to replace or clean the second filter screen 311. The sealing strip 310 on the surface of the bonding plate 309 can ensure the sealing of the circulation box 302 and prevent water leakage.

[0025] Example 2 The rapid cooling device for polyester resin synthesis provided in this embodiment, such as... Figures 6-11As shown, the system includes: a cooling block 306 installed on the inner wall of a water storage tank 3; a cooling assembly 5 including an evaporator 501 located at one end of the lower surface of the inner wall of the water storage tank 3; and a cooling block 306, which is shaped like an inclined plane and located at the upper end of the evaporator 501. A compressor unit 502 is provided at one end of the water storage tank 3, and the compressor unit 502 is connected to the evaporator 501 via a refrigerant pipeline. A first delivery pipe 503 and a second delivery pipe 505 are respectively connected to one side of the water storage tank 3. The connection point between the first delivery pipe 503 and the second delivery pipe 505 is located between the evaporator 501 and the cooling block 306. A first water pump 504 is connected to the other end of the first delivery pipe 503. The first water pump 504 is fixed to one end of the polyester resin synthesis tank 2 via a support plate, and a cooling pipe 507 is connected to the outlet of the first water pump 504. Cooling pipe 507 is arranged around the spiral groove 205 provided in the inner liner 204. The other end of cooling pipe 507 is connected to outlet pipe 510. The other end of outlet pipe 510 passes through polyester resin synthesis tank 2 and is located at the lower end of bottom plate 1. The other end of outlet pipe 510 is connected to one side of the surface of circulation tank 302. A first mounting plate 509 and a second mounting plate 511 are fixedly installed on the lower half of the inner wall of inner liner 204, with the first mounting plate 509 located above the second mounting plate 511. The other end of second conveying pipe 505 is connected to second water pump 506. The outlet of second water pump 506 is connected to an annular coil 508, which is located between the first mounting plate 509 and the second mounting plate 511. One end of discharge pipe 203 passes through the second mounting plate 511 and the first mounting plate 509 and communicates with the cavity of inner liner 204. The other end extends to the outside of polyester resin synthesis tank 2. The annular coil 508 is arranged in a ring shape. The other end of the annular coil 508 is connected to the water outlet pipe 512. One end of the water outlet pipe 512 passes through the second mounting plate 511 and is located on one side of the discharge pipe 203. The other end of the water outlet pipe 512 is connected to one side of the circulation box 302. Switch valves 6 are installed in the middle of the discharge pipe 203, the water outlet pipe 512 and the outlet pipe 510.

[0026] Through the design of the cooling block 306, compressor unit 502, and evaporator 501, the compressor unit 502 is started, and refrigerant is delivered to the evaporator 501 in the water storage tank 3 through the refrigerant pipeline. The evaporator 501 absorbs the heat of the water in the water storage tank 3, causing the water temperature to drop rapidly. The cooling block 306 at the upper end of the evaporator 501 helps to accumulate cold energy, allowing the water in the area between the evaporator 501 and the cooling block 306 to be cooled quickly. After cooling, the cold water enters the first water pump 504 through the first delivery pipe 503. The first water pump 504 pressurizes the cold water and delivers it to the cooling pipe 507. The cooling pipe 507 is arranged to fit tightly against the spiral groove 205 on the outer surface of the inner liner 204 to increase the contact area. Through heat exchange, it absorbs the heat of the inner liner 204 and the internal materials, achieving cooling of the outer liner. Another stream of cold water in the water storage tank 3 enters the second water pump through the second delivery pipe 505. 506. After pressurization, the material is conveyed to the annular coil 508. The annular coil 508 is arranged in a ring between the first mounting plate 509 and the second mounting plate 511 inside the inner liner 204. The material is uniformly stirred on the surface of the first mounting plate 509. The material is directly contacted by the first mounting plate 509 for heat exchange, which quickly removes the heat inside the material. After heat exchange, the water with increased temperature flows back to the circulation box 302 through the outlet pipe 510 and the water outlet pipe 512. When the cooling water is drawn away by the pipe, the inclined cooling block 306 can quickly replenish the water for cooling. Thus, the material can be cooled synchronously by the outer spiral cooling pipe 507 and the inner ring annular coil 508 of the inner liner 204, eliminating local heat exchange blind spots and ensuring that heat is quickly transferred from the inside to the outside of the material, thereby greatly improving the cooling speed.

[0027] In summary, the rapid cooling device for polyester resin synthesis provided in this embodiment has the following advantages: the outer spiral cooling pipe 507 of the inner liner 204 and the inner ring coil 508 of the inner liner 204 can achieve synchronous cooling of the material by wrapping it inside and out, eliminating local heat exchange blind spots in the material, ensuring that heat is quickly transferred from the inside to the outside of the material, thereby greatly improving the cooling speed. The reverse tilting stirring plate 403 can make the material fully mixed, reduce local overheating caused by local material stillness, and ensure that the overall temperature of the material drops uniformly. In addition, the scrapers 405 on both sides of the stirring plate 403 rotate synchronously. Since the tilt angle of the scrapers 405 is the same as that of the stirring plate 403, the scrapers 405 and the wall of the inner liner 204 form a better contact and scraping angle, easily peeling off the material sticking to the wall.

[0028] In use, cooling water is added through the inlet 301 on the upper surface of the water tank 3. The cooling component 5 cools the inner tank 204. Then, the electric push rod 202 drives the top cover 4 to rise. After adding the materials required for polyester resin synthesis into the inner tank 204, the electric push rod 202 retracts, and the top cover 4 descends to fit against the upper surface of the polyester resin synthesis tank 2. The drive motor 401 is started, and its output shaft drives the connecting block 402 to rotate, which in turn drives the stirring plates 403 at both ends to rotate. The counter-tilted stirring plates 403 can make the materials... Thorough mixing reduces localized overheating caused by material stagnation, ensuring a uniform temperature drop across the entire material flow. The scrapers 405 on both sides of the mixing plate 403 rotate synchronously. Since the scraper 405's tilt angle matches that of the mixing plate 403, it creates a better contact and scraping angle with the inner liner 204 wall, easily peeling away materials adhering to the wall. Once the polyester resin cools to the target temperature, the cooling component 5 and drive motor 401 are shut off, and the switch valve 6 on the discharge pipe 203 is opened, allowing the material to be discharged from the inner liner 204 through the discharge pipe 203.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
