Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a self-priming gas-liquid enhanced stirring reaction vessel. Background Technology

[0002] In modern industrial production processes, substances often need to undergo physical or chemical reactions, and a reaction vessel is a container used to carry out physical or chemical reactions.

[0003] However, existing self-priming agitators in reactors mainly utilize the rapid rotation of the hollow impeller to create negative pressure around the impeller as liquid is thrown out, thereby drawing gas from outside the liquid into the liquid. However, because the impeller's rotation causes the liquid to swirl, the liquid at the bottom of the reactor cannot mix with air for a short period, resulting in low mixing efficiency. Therefore, this application provides a self-priming gas-liquid enhanced stirring reactor to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a self-priming gas-liquid enhanced stirring reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-priming gas-liquid enhanced stirring reactor, comprising a cylindrical body, a hollow tube rotatably connected inside the cylindrical body, the upper end of the hollow tube penetrating through the top of the cylindrical body and rotatably connected thereto, a motor fixedly installed at the upper end of the cylindrical body, the output end of the motor fixedly connected to the hollow tube, a support rod fixedly installed at the bottom of the cylindrical body, two first gears fixedly installed on the support rod, four stirring rods rotatably connected at the lower end of the hollow tube, each stirring rod having a stirring blade fixedly installed, a second gear fixedly installed at one end of the inner side of each stirring rod, the second gear being meshed with the first gear, and an air inlet and an exhaust outlet respectively opened at the upper and lower ends of the hollow tube.

[0006] As a further embodiment of this utility model: a plurality of exhaust fans are fixedly installed at the upper end of the hollow tube, the interior of the exhaust fans is hollow and communicates with the interior of the hollow tube, and an exhaust hole is formed in the hollow part of the exhaust fan.

[0007] As a further improvement of this utility model, both the first gear and the second gear are conical.

[0008] As a further embodiment of this utility model: the bottom of the cylinder is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to the hollow tube, and a support rod passes through its axis and is rotatably connected to it.

[0009] As a further embodiment of this utility model, a rotating plate is fixedly installed at the upper end of the support rod, and the rotating plate is rotatably connected to the inner wall of the hollow tube.

[0010] As a further improvement of this utility model, a fixing plate is fixedly installed inside the hollow tube. The fixing plate is located at the penetration point between the exhaust fan and the hollow tube, and divides the interior of the hollow tube into upper and lower layers.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the motor drives the stirring rod and the exhaust fan to rotate through the hollow tube. When the exhaust fan rotates, it pushes the liquid around the hollow tube outward to create a pressure difference. The air inlet draws in the outside air into the hollow tube and delivers the gas directly to the interior of the liquid through the exhaust fan and the exhaust port, so that it mixes with the liquid.

[0012] In addition, while the stirring rod revolves around the hollow tube, one end of the stirring rod is connected to a fixedly mounted first gear via a second gear. Therefore, as the stirring rod revolves, it rotates on its own axis through the interaction of the second and first gears. Simultaneously, the stirring rod drives the stirring blades to rotate, disrupting the liquid and preventing vortices from forming during rotation, which would result in poor mixing. At the same time, the stirring blades on the upper set of stirring rods lift some of the liquid during rotation, allowing it to mix with the air at the top of the cylinder.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] refer to Figure 1 This is a schematic diagram of the overall structure of the reactor. A rotating shaft 11 is rotatably connected to the central axis inside the cylindrical body 1. A hollow tube 2 is fixedly installed at the upper end of the rotating shaft 11, and the upper end of the hollow tube 2 passes through the top of the cylindrical body 1 and is rotatably connected to it. Four mounting posts 12 are fixedly installed at the upper end of the cylindrical body 1, and a motor 21 is fixedly installed at the upper end of the four mounting posts 12. The output end of the motor 21 is fixedly connected to the hollow tube 2. Figure 2 and 4 As shown, the upper end of the hollow tube 2 has an air inlet 22 located outside the cylinder 1. Several exhaust fans 23 are fixedly installed at the upper end of the hollow tube 2. The exhaust fans 23 are hollow and communicate with the interior of the hollow tube 2, forming an exhaust hole 231 in the hollow part of the exhaust fan 23. The exhaust fans 23 are located inside the cylinder 1 and are in contact with the liquid inside the cylinder 1. Four stirring rods 24 are provided at the lower end of the hollow tube 2, with two stirring rods 24 forming a group, and the two groups of stirring rods 24 are distributed vertically. The output end of the motor 21 drives the hollow tube 2 to rotate, and the hollow tube 2 rotates more stably inside the cylinder 1 through the rotating shaft 11. Furthermore, when the hollow tube 2 rotates, it drives the exhaust fan 23 to rotate synchronously, displacing the nearby liquid and causing the liquid to move violently, thereby creating a low pressure at the center of the hollow tube 2. Under the action of the pressure difference, the gas in the external space is drawn in through the air inlet 22. The gas passes through the hollow tube 2 and is then discharged from the exhaust fan 23 and the exhaust port 231, so that the gas and liquid are in full contact.

[0022] However, the above problems include: when the stirring rod 24 rotates continuously, it creates a vortex in the liquid, preventing the liquid at the bottom from mixing well with the air. Air reaches the interior of the liquid through the hollow tube 2, exhaust fan 23, and exhaust port 231, directly contacting it. However, the air rises to the upper part of the cylinder 1 and separates from the liquid, resulting in some air failing to mix with the liquid. Therefore, the following technical solution is used to improve this.

[0023] Specifically, such as Figure 4 and Figure 3As shown, a support rod 3 is installed at the lower end of the hollow tube 2. The lower end of the support rod 3 passes through and is rotatably connected to the rotating shaft 11. The lower end of the support rod 3 is fixedly connected to the bottom of the cylinder 1. Two sets of first gears 31 are fixedly installed on the support rod 3. The first gears 31 are conical and distributed vertically. One end of the stirring rod 24 passes through and is rotatably connected to the hollow tube 2. A second gear 32 is fixedly installed on the inner end of the stirring rod 24. The second gear 32 is conical and meshes with the first gear 31. Each stirring rod 24 has four symmetrically distributed stirring blades 33 fixedly installed. When the hollow tube 2 rotates, it drives the stirring rod 24 to revolve around the hollow tube 2 as the axis, thereby stirring the liquid. Furthermore, as the stirring rod 24 revolves, the second gear 32 at its inner end moves synchronously. Since the second gear 32 is meshed with the first gear 31, its movement causes the fixedly installed first gear 31 to rotate. This rotation of the second gear 32 drives the stirring rod 24 to rotate on its own axis. During this rotation, the stirring rod 24 drives the stirring blades 33 to rotate synchronously. The stirring blades 33 disrupt the liquid to a certain extent, preventing the formation of vortices that would result in poor mixing between the liquid and air. Additionally, the upper stirring blades 33, when rotating, lift the liquid upwards, causing some of it to be thrown up and thus fully mixed with the air inside the cylinder 1. This reduces the mixing time between the liquid and air.

[0024] Preferably, the rotatable connection between the stirring rod 24 and the hollow tube 2 is a machine seal to prevent the stirred liquid from entering the interior of the hollow tube 2 through the gap and causing corrosion to the first gear 31 and the second gear 32.

[0025] Preferably, a rotating plate 4 is fixedly installed on the upper end of the support rod 3. The rotating plate 4 is rotatably connected to the inner wall of the hollow tube 2 to prevent the upper end of the support rod 3 from tilting when the hollow tube 2 rotates due to the meshing connection between the first gear 31 and the second gear 32, which would cause the axis of the first gear 31 to shift and prevent it from meshing with the second gear 32.

[0026] Preferably, a fixing plate 41 is fixedly installed inside the hollow tube 2. The fixing plate 41 is located at the lower end of the connection between the exhaust fan 23 and the hollow tube 2. The fixing plate 41 divides the interior of the hollow tube 2 into upper and lower layers, so that the lower layer of the hollow tube 2 is in a sealed space. This prevents the first gear 31 and the second gear 32 inside from coming into contact with the liquid.

[0027] Preferably, the stirring blades 33 on the two sets of stirring rods 24 are staggered. Figure 5 (As shown), to avoid interference between the stirring blades 33 on the two sets of stirring rods 24 when they rotate.

[0028] Working Principle: The hollow tube 2 is driven to rotate by the motor 21. As the hollow tube 2 rotates, it drives the stirring rod 24 and the exhaust fan 23 to rotate as well. The exhaust fan 23, when rotating, displaces the liquid around the hollow tube 2, creating a pressure difference. This allows air from outside the cylinder 1 to be drawn into the hollow tube 2 through the air inlet 22, and then directly delivered to the liquid interior through the exhaust fan 23 and exhaust port 231, mixing it with the liquid. Simultaneously, the stirring rod 24, while revolving around the hollow tube 2, has its inner end connected to a fixedly installed first gear 31 via a second gear 32. Therefore, when the stirring rod 24 revolves, it rotates on its own axis through the second gear 32 and the first gear 31. This rotation of the stirring rod 24 also drives the stirring blades 33 to rotate, preventing vortices in the liquid during the rotation of the stirring rod 24 and ensuring good mixing. Furthermore, the stirring blades 33 on the upper set of stirring rods 24 lift some of the liquid during rotation, allowing it to mix with the air at the top of the cylinder 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
