Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly resin production technology, specifically to a reaction vessel for preparing environmentally friendly resin. Background Technology

[0002] In the preparation of environmentally friendly resins, the reaction vessel is one of the key pieces of equipment. During actual use, the stirring process inside the reaction vessel generates a large amount of heat. Currently, a suitable amount of coolant is usually added to cool it down. However, when adding the coolant, it is generally poured directly into the reaction vessel. This coolant cannot quickly penetrate to the bottom of the environmentally friendly resin reaction system, which may cause local temperature differences and uneven mixing, thus affecting the quality of the prepared environmentally friendly resin.

[0003] Therefore, we propose an environmentally friendly resin preparation reactor. Utility Model Content

[0020] 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. Example

[0021] Please see Figures 1-5 The diagram shows an environmentally friendly resin preparation reactor, including a reactor body 1. A discharge pipe 101 is located at the bottom of the reactor body 1. Multiple support columns 102 are fixedly connected to the bottom of the reactor body 1. A top cover 2 is located at the top of the reactor body 1, and a feed pipe 14 is connected to the top cover 2. A stirring shaft 3 is rotatably connected to the top cover 2. One end of the stirring shaft 3 is connected to a motor 13. An inner shaft 4 is located inside the stirring shaft 3. One end of the inner shaft 4 is fixedly connected to an input gear 5, which is connected to a motor 12. Multiple positioning mechanisms 6 are fixed to the inner shaft 4. Each positioning mechanism 6 consists of a shell 601, a limiting block 602, and a tensioning block 603. The magnetically attached limiting block 602 is connected to the inner wall of the outer shell 601, and the tensioning block 603 is connected to the inner shaft 4. The conical gear 7 is fixedly connected to the inner shaft 4, and the output gear 8 is driven by the conical gear 7. The output gear 8 is fixedly connected to the connecting shaft 9, and the stirring blade 10 is fixedly connected to the connecting shaft 9. The motor 13 and the motor 12 are both fixedly connected to the top of the top cover 2 through the support rod 15, so that the stirring blade can rotate through the conical gear, the output gear and the connecting shaft, thereby effectively stirring the coolant evenly, improving the penetration rate of the coolant and ensuring the temperature uniformity and mixing uniformity of the reaction system.

[0022] Furthermore, the stirring blades 10 are arranged in a ring shape, and the interior of the stirring blades 10 is hollow. The ring shape of the stirring blades and the hollow interior of the stirring blades reduce the weight of the stirring blades, thereby reducing the power required for the stirring shaft to rotate. Secondly, the hollow structure provides a certain amount of elastic space for the stirring blades. When the stirring blades rotate in the reaction system, they can better adapt to the flow and changes of materials, avoiding uneven stirring caused by the viscosity or agglomeration of materials.

[0023] Furthermore, the connecting shaft 9 is rotatably connected to the sealing cover 11, and the sealing cover 11 is fixedly connected to the stirring shaft 3. One end of the connecting shaft is fixedly connected to the stirring blade, the middle of the connecting shaft is fixedly and rotatably connected to the sealing cover, and the other end is rotatably connected to the inner shaft. This not only ensures the sealing of the inside of the reactor and prevents gas or liquid leakage during the reaction process, but also allows for easy disassembly and installation when maintenance or replacement is required, thus improving the maintainability and efficiency of the equipment.

[0024] Furthermore, an agitator 301 is provided on the outside of the agitator shaft 3. The agitator 301 is frictionally connected to the inner wall of the vessel body 1. The agitator is added to the outside of the agitator shaft, and the agitator is an extension structure fixed to the outside of the agitator shaft. It forms a frictional connection with the inner wall of the vessel body. During the rotation, the agitator not only pushes the material to move circumferentially, but also drives the material to move axially through friction, thereby achieving a more three-dimensional and more uniform mixing effect.

[0025] Furthermore, one end of the connecting shaft 9 is spherical, and the connecting shaft 9 is rotatably connected to the inner shaft 4. It is connected to the spherical end of the connecting shaft through a groove opened in the inner shaft, thereby ensuring the stability of the stirring blades and ensuring precise meshing between the gears.

[0026] Furthermore, the tensioning block 603 is frictionally connected to one side of the limiting block 602, while the other side of the limiting block 602 is tightly pressed against the inner wall of the stirring shaft 3. By frictionally connecting one side of the limiting block to the tensioning block, and the other side of the limiting block being tightly pressed against the inner wall of the stirring shaft, the limiting block is secured in a specific position through friction. This not only ensures the stability of the connection but also has a certain degree of self-adaptability, ensuring that the inner shaft can maintain precise positioning when operating at high speed, thus improving the operational stability of the entire stirring system.

[0027] Furthermore, the limiting block 602 is slidably connected to the outer shell 601. One side of the limiting block 602 is inclined, allowing it to slide inside the outer shell. The inclined design of one side not only ensures that the limiting block can move flexibly inside the outer shell, but also enables precise positioning and fine-tuning of the stirring shaft or related components.

[0028] In this scheme, the workflow is as follows: First, the material is fed through the feed pipe in the top cover 2 and discharged through the discharge pipe in the vessel body 1. Then, the torque is transmitted to the inner shaft 4 by the input gear 5 driven by the motor 12. After that, the tension block 603 of the positioning mechanism 6 applies radial pressure to the inner shaft 4 through thread adjustment to prevent the inner shaft from sliding relative to the stirring shaft 3 during operation. The limit block 602 fixes the axial position by magnetic attraction to prevent the inner shaft from deviating.

[0029] The inner shaft 4 drives the bevel gear 7 to rotate, and the power is transmitted to the output gear 8 through gear meshing.

[0030] The meshing design of the bevel gear set changes the direction of rotation from the vertical inner axis to the horizontal connecting axis.

[0031] The output gear 8 drives the connecting shaft 9 and the stirring blade 10 to rotate at high speed around the horizontal axis.

[0032] The stirring blades 10 shear, mix, or disperse the material inside the vessel 1 to achieve homogenization.

[0033] The magnetic limiting block 602 and the tensioning block 603 of the positioning mechanism 6 work together to ensure that the inner shaft 4 remains stable during high-speed rotation, reducing vibration and wear.
