[0002] Unsaturated resin is a polymer material with good plasticity and formability. After curing, it has advantages such as high strength, corrosion resistance and good insulation. It is widely used in fiberglass products, coatings, adhesives and other fields. Its production process requires raw material mixing, reaction and other steps, and has high requirements for temperature control.

[0003] Most existing mixing tanks used for unsaturated resin production are vertical tank structures with a stirring paddle inside. The mixing of raw materials is achieved by motor drive. The tank has a feed inlet at the top and a discharge outlet at the bottom. Some tanks have a simple insulation layer on the outer wall, while a few are equipped with basic air-cooling devices or jacketed cooling structures to regulate the temperature through natural heat dissipation or short-term circulation of cold water.

[0004] However, existing mixing tanks have low cooling medium utilization and slow temperature regulation. Especially in large-scale production, the raw materials may react excessively due to untimely cooling, which reduces the stability of product quality. Therefore, a cooling mixing tank for unsaturated resin production is proposed to solve the above problems. Utility Model Content

[0011] 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.

[0012] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5This utility model provides an embodiment of a cooling mixing tank for unsaturated resin production, including a bottom frame 1. A shell 2 is fixedly connected to the top of the bottom frame 1. The shell 2 can prevent external debris from interfering with the operation of the equipment and can also form a relatively closed space during heat dissipation to help improve heat dissipation efficiency. A mixing tank 14 is installed inside the shell 2. The mixing tank 14 is a container for mixing unsaturated resin raw materials. A stirring component is installed inside the mixing tank 14 to achieve uniform mixing of raw materials. A heat dissipation component is installed on the outside of the mixing tank 14 to quickly dissipate the heat generated during the mixing process. A feed pipe 6 is installed on the top of the mixing tank 14 to ensure that the raw materials are poured into the mixing tank 14 smoothly and continuously. A discharge pipe 8 is fixedly connected to one side of the mixing tank 14 to smoothly export the finished product to the subsequent processing equipment. The heat dissipation assembly includes heat dissipation fins 12, which are fixedly connected to the outside of the mixing tank 14. The heat dissipation fins 12 are made of a metal with excellent thermal conductivity, which can quickly conduct heat from inside the mixing tank 14 to its own surface. An annular nozzle 13 is installed on the top of the outer shell 2. The nozzle holes of the annular nozzle 13 are evenly distributed, which can spray cold water evenly and comprehensively onto the surface of the heat dissipation fins 12 and the mixing tank 14. A water pump 3 and a water tank 5 are installed on the top of the bottom frame 1. The water tank 5 is used to store the cold water required for heat dissipation. The input end of the water pump 3 is fixedly connected to the outside of the water tank 5 through a pipe, which can stably draw cold water from the water tank 5. The output end of the water pump 3 is fixedly connected to the outside of the annular nozzle 13 through a pipe, thereby pressurizing and delivering cold water to the annular nozzle 13. The nozzle 13 sprays water. A second water pump 4 is installed on the top of the base frame 1. The input end of the second water pump 4 is fixedly connected to the bottom of the outer shell 2 through a pipe, and the output end of the second water pump 4 is fixedly connected to the outside of the water tank 5 through a pipe. It can extract the water collected at the bottom of the outer shell 2 after heat dissipation, realize the recycling of cold water, and reduce water consumption. Two bases 22 are fixedly connected to the top of the base frame 1. The first water pump 3 and the second water pump 4 are respectively installed on the top of the two bases 22. The bases 22 are made of wear-resistant and shock-absorbing materials. The top of the water tank 5 is fixedly connected to the water inlet pipe 9. The water inlet pipe 9 can be connected to an external water supply device. When the cold water in the water tank 5 is insufficient due to evaporation, leakage, etc., cold water can be replenished to the water tank 5 in time through the water inlet pipe 9.

[0013] Reference Figure 1 and Figure 6The mixing assembly includes a motor 18, which serves as the power source for mixing. The motor 18 is fixedly connected to the bottom of the mixing tank 14. The output end of the motor 18 is fixedly connected to a rotating shaft 17, which can efficiently transmit the power of the motor 18 to the mixing components. A scraper blade 15 is fixedly connected to the outside of the rotating shaft 17. When the rotating shaft 17 drives it to rotate, it can accurately scrape off the raw materials adhering to the edge of the mixing tank 14, avoiding waste and uneven mixing caused by raw material residue. Multiple inclined blades 16 are fixedly connected inside the scraper blade 15. The inclined blades 16 are distributed at a certain angle, which can generate an upward pushing force on the raw materials in the mixing tank 14, further improving the uniformity of mixing. A protective box 19 is fixedly connected to the bottom of the mixing tank 14. The motor 18 is installed inside the protective box 19. The protective box 19 can isolate the motor 18 from external dust, moisture, and heat transmitted from the bottom of the mixing tank 14. The protective box 19 is located at the bottom of the base frame 1.

[0014] Reference Figure 1 and Figure 3 Two fans 10 are installed on the outside of the outer casing 2. During the heat dissipation process, the fans 10 can accelerate the airflow inside and outside the outer casing 2 after starting, so that the water mist sprayed by the ring nozzle 13 can quickly exchange heat with the air. A mounting frame 11 is fixedly connected to the outside of the fan 10. The mounting frame 11 provides a stable mounting carrier for the fan 10. The mounting frame 11 is fixedly connected to the outside of the outer casing 2 by screws 20. The screw connection method is not only stable, but also facilitates the disassembly, maintenance or replacement of the fan 10 in the future. A protective frame 7 is fixedly connected to the outside of the mounting frame 11. The protective frame 7 can effectively prevent external objects from directly colliding with the fan 10. The fan 10 is located inside the protective frame 7. Multiple ventilation meshes 21 are fixedly connected to the outside of the protective frame 7.

[0015] Working principle: First, the raw materials are poured into the feed pipe 6. After the raw materials enter the mixing tank 14, the motor 18 is started. The motor 18 drives the rotating shaft 17 to rotate, which in turn drives the scraper blade 15 to rotate. The scraper blade 15 can scrape off the raw materials adhering to the edge of the mixing tank 14 and add them to the mixing process, avoiding uneven mixing and waste caused by raw materials remaining on the inner wall of the mixing tank 14. In addition, the rotation of the scraper blade 15 will drive the inclined blade 16 to rotate. The inclined blade 16 has a certain tilt angle, which can make the raw materials in the mixing process have an upward trend, continuously conveying the raw materials at the bottom to the top, realizing repeated mixing and making the mixing more uniform.

[0016] Secondly, during the mixing of raw materials, a reaction occurs and heat is generated. At this time, water pump 3 is started to draw cold water from water tank 5 and deliver it to annular nozzle 13. Then, the annular nozzle 13 sprays the water onto the surface of mixing barrel 14. Through the heat dissipation fins 12, the contact area between the cold water and mixing barrel 14 is increased, enhancing the heat dissipation capacity. The water flows down along the heat dissipation fins 12. Afterward, water pump 4 is started to draw out the water that has flowed down and refill it into water tank 5. In addition, the fan 10 is started during the heat dissipation process, which can make the sprayed water mist dissipate heat faster, improve the heat dissipation efficiency, and help to achieve a rapid heat dissipation process.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
