Description

Technical Field

[0001] This utility model relates to a resin distillation and dehydration device. Background Technology

[0002] During resin synthesis and processing, moisture generated in the reaction or introduced by raw materials can seriously affect product performance and subsequent processes. Therefore, it is necessary to effectively remove it by distillation to obtain pure, high-quality resin products.

[0003] Currently, jacketed reactors are commonly used in industry for this operation. However, the heat can only be transferred unidirectionally through the reactor wall, resulting in low heat transfer efficiency for high-viscosity resins. This leads to difficulties in internal heating, slow dehydration, and high energy consumption. Utility Model Content

[0004] The main objective of this invention is to provide a resin distillation and dehydration device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution: A resin distillation and dehydration device includes a tank body with a jacket on the outside. A rotating tube is located at the center of the tank body, and a main stirring rod is installed on the outer wall of the rotating tube. A heating tube is installed inside the rotating tube, with both the medium inlet and outlet of the heating tube extending beyond the top of the tank body. A driven gear is installed at the top of the rotating tube, and a driving gear meshes with one side of the driven gear. The driving gear is connected to the output shaft of a motor. A feed pipe and an air outlet pipe are respectively installed on both sides of the top of the tank body, and a discharge pipe is installed at the bottom of the tank body.

[0006] Preferably, a partition is provided on the upper part of the tank body, and the partition is provided with an inlet and an outlet that are respectively connected to the feed pipe and the air outlet pipe.

[0007] Preferably, both the driven gear and the driving gear are disposed between the partition and the inner wall of the top of the tank, and the rotating tube passes through the partition and is rotatably connected to the partition.

[0008] Preferably, the heating tube has a spiral structure.

[0009] Preferably, the main stirring rod has a main cavity inside, and the main cavity is connected to the rotating tube.

[0010] Preferably, the main stirring rods are provided in three groups, and the three groups of main stirring rods are evenly distributed along the length of the rotating tube. Each group of main stirring rods is provided with three main stirring rods, and the three main stirring rods are evenly distributed along the circumference of the rotating tube.

[0011] Preferably, the bottom of the rotating tube is provided with two bottom stirring rods, and the bottom stirring rods are provided with bottom cavities, which are connected to the rotating tube.

[0012] Preferably, the bottom stirring rod has an L-shaped structure, and two bottom stirring rods are symmetrically arranged at the bottom of the rotating tube.

[0013] The beneficial technical effects of this utility model are as follows: The outer jacket and internal heating tubes of this invention form a highly efficient dual heating system. The jacket enables rapid overall heating and continuous heat preservation of the tank, reducing heat loss. The heating tubes inside the rotating tube directly supply energy to the central area of ​​the resin, and the heat is rapidly transferred to the main stirring rod on the outer wall through the rotating tube, achieving uniform heat diffusion throughout the entire area. The synergistic effect of both significantly improves heat transfer efficiency, solving the problem of difficult internal heating when heating high-viscosity resins in traditional equipment, and providing a reliable guarantee for the efficient and deep dehydration of high-viscosity resins.

[0016] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0017] like Figures 1-7As shown, the resin distillation and dehydration device provided in this embodiment includes a tank 1, a jacket 2 on the outside of the tank 1, a rotating tube 3 at the center inside the tank 1, a main stirring rod 4 on the outer wall of the rotating tube 3, a heating tube 5 inside the rotating tube 3, and the medium inlet and medium outlet of the heating tube 5 extending out of the top of the tank 1. A driven gear 6 is provided at the top of the rotating tube 3, and a driving gear 7 meshes with one side of the driven gear 6. The driving gear 7 is connected to the output shaft of the motor 8. A feed pipe 9 and an air outlet pipe 10 are respectively provided on the top two sides of the tank 1, and a discharge pipe 11 is provided at the bottom of the tank 1.

[0018] The jacket 2 on the outside of the tank 1 and the heating tube 5 inside form a dual heating system. The jacket 2 can achieve rapid heating and full-process heat preservation of the tank 1, reducing heat loss. The heating tube 5 inside the rotating tube 3 directly supplies energy to the central area of ​​the resin. The heat is quickly transferred to the main stirring rod 4 on the outer wall through the rotating tube 3, achieving uniform diffusion of heat throughout the entire area.

[0019] Valves are installed on the feed pipe 9, the air outlet pipe 10, and the discharge pipe 11.

[0020] A connecting shaft is provided above the drive gear 7. The connecting shaft passes through the top of the tank 1 and is fixedly connected to the output shaft of the motor 8. A bearing is provided at the position where the connecting shaft passes through the tank 1 to ensure the rotation effect.

[0021] A heat medium inlet pipe is provided at the bottom of one side of the jacket 2, and a heat medium outlet pipe is provided at the top of the other side.

[0022] In this embodiment, as Figure 2 As shown, a partition 12 is provided on the upper part of the tank body 1. The partition 12 is provided with a feed port 13 and an air outlet 14 that are respectively connected to the feed pipe 9 and the air outlet 10. The driven gear 6 and the driving gear 7 are both provided between the partition 12 and the inner wall of the top of the tank body 1. The rotating pipe 3 passes through the partition 12 and is rotatably connected to the partition 12.

[0023] The partition 12 creates a space within the tank 1 to prevent the driven gear 6 and the driving gear 7 from coming into contact with the resin and affecting the transmission. The bottoms of both the driven gear 6 and the driving gear 7 are rotatably connected to the partition 12 via bearings.

[0024] In this embodiment, as Figure 6 As shown, the heating tube 5 has a spiral structure, which can significantly increase the effective heat exchange area of ​​the heating tube 5 inside the rotating tube 3 and improve the efficiency of internal heating.

[0025] In this embodiment, as Figure 2As shown, the main stirring rod 4 has a main cavity 15 inside, which is connected to the rotating tube 3. This further expands the heat transfer area and improves heat utilization. The heat transferred by the rotating tube 3 can be diffused to the entire interior of the main stirring rod 4 through the connected main cavity 15, avoiding the problem of insufficient end temperature caused by only surface heat transfer and enhancing the heat transfer effect.

[0026] In this embodiment, as Figure 5 As shown, there are three sets of main stirring rods 4. The three sets of main stirring rods 4 are evenly distributed along the length of the rotating tube 3. Each set of main stirring rods 4 has three rods. The three main stirring rods 4 are evenly distributed along the circumference of the rotating tube 3 to achieve all-round stirring of the resin in the tank 1.

[0027] In this embodiment, as Figure 2 As shown, two bottom stirring rods 16 are provided at the bottom of the rotating tube 3. The bottom stirring rods 16 are provided with bottom cavities 17, which are connected to the rotating tube 3, so that the bottom area of ​​the tank 1 can also obtain heat, ensuring that the moisture in the bottom resin can also be vaporized efficiently.

[0028] In this embodiment, as Figure 2 As shown, the bottom stirring rod 16 has an L-shaped structure, and two bottom stirring rods 16 are symmetrically arranged at the bottom of the rotating tube 3 to adapt to the shape of the bottom of the tank 1, resulting in better stirring effect.

[0029] In summary, in this embodiment, the outer jacket 2 of the tank 1 and the internal heating tube 5 form a highly efficient dual heating system. The jacket 2 enables rapid overall heating and full-process heat preservation of the tank 1, reducing heat loss. The heating tube 5 inside the rotating tube 3 directly supplies energy to the central area of ​​the resin, and the heat is rapidly transferred to the main stirring rod 4 on the outer wall through the rotating tube 3, achieving uniform heat diffusion throughout the entire area. The synergistic effect of both significantly improves heat transfer efficiency, solving the problem of difficult internal heating when heating high-viscosity resins in traditional equipment, and providing a reliable guarantee for the efficient and deep dehydration of high-viscosity resins.
