Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically a reaction vessel capable of uniform mixing. Background Technology

[0002] Reactors are used in chemical, pharmaceutical, food, and coating industries, and are usually equipped with stirring devices to ensure thorough mixing of materials.

[0003] In chemical processes, traditional single-shaft stirred reactors are prone to forming dead zones due to the limitations of fluid dynamics, resulting in uneven mixing of materials, especially for non-Newtonian fluids or systems with high solid content. At the same time, the side-mounted or top-mounted hopper design is prone to bridging or segregation due to the particle migration effect driven by gravity, resulting in uneven material distribution, which affects the reaction effect and product quality. Summary of the Invention

[0004] The purpose of this invention is to provide a reaction vessel capable of uniform mixing, in order to solve the problems mentioned in the background art.

[0005] A reaction vessel capable of uniform mixing includes a vessel body, a vessel cover installed on the vessel body by bolts and fasteners, a feed hopper provided on the vessel cover, multiple sets of support legs fixedly connected to the outer wall of the bottom end of the vessel body, a discharge pipe connected to the bottom end of the vessel body, and a first stirring assembly and a second stirring assembly installed on the vessel body.

[0006] The first stirring assembly includes a first stirring motor and a rotating rod. The first stirring motor is mounted on the lid of the vessel, and the rotating rod is rotatably mounted inside the vessel body. One end of the rotating rod is connected to the first stirring motor. Multiple stirring rods are equidistantly mounted on the rotating rod.

[0007] The second stirring assembly includes a rotating shaft. Multiple sets of the rotating shafts are arranged in multiple layers at equal intervals around the inside of the vessel body. The rotating shafts are rotatably connected to the vessel body, and one end of the rotating shaft penetrates the inside of the vessel body. A stirring blade is fixed to the end of the rotating shaft inside the vessel body. Multiple sets of stirring blades and multiple sets of stirring rods are arranged alternately. The ends of the multiple sets of rotating shafts located outside the vessel body are connected by a pulley system. A second stirring motor is installed on the outer wall of the vessel body, and one set of rotating shafts is connected to the second stirring motor by transmission.

[0008] The bottom of the feed hopper is inclined and connected to multiple sets of first discharge pipes, and the other end of the first discharge pipe is fixed to a second discharge pipe. One end of the second discharge pipe passes through the lid and extends into the interior of the vessel.

[0009] The end of the second feeding pipe away from the first feeding pipe is rotatably connected to an L-shaped feeding pipe via a rotary joint. A driven gear is fixedly connected to the outer wall of one end of the L-shaped feeding pipe, and a connecting frame is fixedly connected to one end of the rotating rod. A transmission gear ring that meshes with multiple sets of driven gears is fixedly connected to the connecting frame.

[0010] An installation plate is fixedly connected to the inside of one end of the L-shaped feeding pipe. A stirring screw is fixedly connected to both sides of the installation plate. One set of stirring screws extends into the inside of the second feeding pipe, and the other set of stirring screws extends into the inside of the L-shaped feeding pipe.

[0011] The bottom of the support leg is equipped with a rubber pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a first stirring motor to drive a rotating rod, which in turn drives multiple sets of stirring rods to rotate, forming an axial flow field to achieve initial mixing of materials. Simultaneously, a second stirring motor drives a multi-layered rotating shaft arranged around the material via a pulley assembly, causing the staggered stirring blades to generate radial shear flow. This breaks the dead zone in the flow field commonly found in traditional single-axis stirring. Through the synergistic effect of the axial and radial flow fields, not only can material bridging or segregation be effectively reduced, but the mixing uniformity of materials can also be significantly improved, thereby optimizing the reaction effect and product quality, and ensuring the efficient and safe conduct of the reaction process.

[0014] Material is added through the feed hopper and evenly distributed to multiple feeding paths via multiple sets of first feeding pipes to expand the feeding area and prevent bridging. Then, the second feeding pipe guides the material into the interior of the vessel. The rotation of the rotating rod drives the transmission gear ring, causing multiple sets of L-shaped feeding pipes to rotate synchronously, further expanding the feeding area and ensuring even distribution of the material. The rotation of the L-shaped feeding pipes drives the stirring screw to rotate and stir the material, which helps to disperse the material and prevents blockage, ensuring smooth feeding.

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.

[0021] Please see Figures 1-4 As shown, a uniformly mixing reactor includes a vessel body 1, a vessel cover 2 fastened to the vessel body 1 by bolts, a feed hopper 3 on the vessel cover 2, multiple sets of support legs 4 fixedly connected to the outer wall of the bottom end of the vessel body 1, a discharge pipe 5 connected to the bottom end of the vessel body 1, and a first stirring assembly and a second stirring assembly mounted on the vessel body 1. The first stirring assembly includes a first stirring motor 6 and a rotating rod 7. The first stirring motor 6 is mounted on the vessel cover 2, and the rotating rod 7 is rotatably mounted inside the vessel body 1, with one end of the rotating rod 7 being drively connected to the first stirring motor 6. Multiple sets of stirring rods 8 are equidistantly mounted on the rotating rod 7. The second stirring assembly includes a rotating shaft 9. Multiple sets of rotating shafts 9 are arranged in a multi-layered, equidistant ring inside the reactor body 1. The rotating shafts 9 are rotatably connected to the reactor body 1, with one end of each shaft penetrating the interior of the reactor body 1. A stirring blade 10 is fixed to the end of each shaft 9 inside the reactor body 1. Multiple sets of stirring blades 10 and multiple sets of stirring rods 8 are arranged in an alternating pattern. The ends of the multiple sets of rotating shafts 9 located outside the reactor body 1 are connected via a pulley group 11. A second stirring motor 12 is installed on the outer wall of the reactor body 1, and one set of rotating shafts 9 is connected to the second stirring motor 12 in a transmission manner. The reactor body 1 is the main structure of the reactor. The reactor cover 2 is fastened to the reactor body 1 with bolts to ensure the airtightness of the reaction environment. A feed hopper 3 is provided on the reactor cover 2 for adding materials into the reactor. Multiple sets of support legs 4 support the entire reactor. A discharge pipe 5 discharges the product after the reaction. The first stirring assembly is used for preliminary stirring of the materials. The multiple sets of stirring blades 10 and multiple sets of stirring rods 8 of the second stirring assembly are arranged in an alternating pattern to achieve more thorough mixing.

[0022] Working steps: First, add materials into the vessel 1 through the feed hopper 3. Then, start the first stirring motor 6 and the second stirring motor 12 to drive the stirring rods 8 on the rotating rod 7 and the stirring blades 10 on the rotating shaft 9 to stir. During this process, the first stirring motor 6 drives the rotating rod 7 to rotate multiple sets of stirring rods 8, forming an axial flow field to complete the initial mixing. At the same time, the second stirring motor 12 drives the multi-layered rotating shaft 9 through the pulley group 11, so that the staggered stirring blades 10 generate radial shear flow, breaking the dead zone of the flow field in traditional single-axis stirring, so as to achieve the synergistic effect of axial and radial flow fields and reduce material bridging or segregation.

[0023] Please see Figures 1-4As shown, the bottom of the feed hopper 3 is inclined and surrounded by multiple sets of first feed pipes 13, and the other end of the first feed pipe 13 is fixedly connected to a second feed pipe 14. One end of the second feed pipe 14 passes through the lid 2 and extends into the interior of the vessel body 1. The end of the second feed pipe 14 away from the first feed pipe 13 is rotatably connected to an L-shaped feed pipe 16 through a rotary joint 15. A driven gear 17 is fixedly connected to the outer wall of one end of the L-shaped feed pipe 16. A connecting frame 18 is fixedly connected to one end of the rotating rod 7. A transmission gear ring 19 that meshes with multiple sets of driven gears 17 is fixedly connected to the connecting frame 18. A mounting plate 20 is fixedly connected to the inside of one end of the L-shaped feed pipe 16. Both sides of the mounting plate 20 are fixedly connected to... The stirring screws 21 are arranged in two groups: one group extends into the second feed pipe 14, and the other group extends into the L-shaped feed pipe 16. Rubber pads are provided at the bottom of the support legs 4. The first feed pipe 13 distributes the material from the feed hopper 3 into multiple second feed pipes 14 to prevent material accumulation caused by concentrated feeding. The second feed pipes 14 further guide the material into the reactor body 1. The stirring screws 21 agitate the material during feeding, aiding in initial mixing and dispersion, and reducing blockages in the feed pipes. The rubber pads increase friction with the ground, improving the stability of the reactor.

[0024] Working steps: First, material is added into the vessel 1 through the feed hopper 3. The bottom of the feed hopper 3 is inclined and surrounded by multiple sets of first discharge pipes 13, which evenly distribute the material to multiple discharge paths, expanding the discharge area. The second discharge pipe 14 further guides the material into the interior of the vessel 1. At the same time, when the rotating rod 7 rotates, it drives the transmission gear ring 19 to rotate through the connecting frame 18, which in turn meshes with multiple sets of driven gears 17, so that multiple sets of L-shaped discharge pipes 16 rotate synchronously, further expanding the discharge area and improving the uniform distribution of material in the vessel 1. When the L-shaped discharge pipes 16 rotate, they drive two sets of stirring screws 21 to rotate through the mounting plate 20, which stirs the material during the discharge process, helps to disperse the material, reduces the blockage of the discharge pipes, and ensures the smooth progress of the discharge process.
