Description

Technical Field

[0001] This utility model relates to the field of reaction vessel equipment technology, and in particular to a reaction vessel stirring device. Background Technology

[0002] A reaction vessel is a container used for chemical reactions. Its structure and parameters are typically designed and configured according to different process requirements. The design conditions, processes, inspection, manufacturing, and acceptance of a reaction vessel must adhere to relevant technical standards to achieve the heating, evaporation, cooling, and low-to-high-speed mixing reaction functions required by the process. Reaction vessels are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. They are fundamental equipment in pharmaceutical raw material plants, often used for the reaction of several raw materials to purify them. A reaction vessel can provide the necessary environment, temperature, and pressure for the reaction.

[0003] Currently, Chinese Patent Publication No. CN221714320U discloses an adjustable reactor stirring mechanism and reactor. The adjustable reactor stirring mechanism includes a driving component, a driving shaft, a first stirring paddle, a second stirring paddle, an adjusting shaft, and an adjusting member. The output end of the driving component is connected to the driving shaft. The adjusting shaft is located inside the driving shaft and is coaxial with the driving shaft. The surface of the driving shaft is provided with a first opening groove and a second opening groove. The adjusting shaft is provided with a first threaded portion and a second threaded portion corresponding to the first opening groove and the second opening groove, respectively. The thread directions of the first threaded portion and the second threaded portion are opposite. The first stirring paddle and the second stirring paddle are threadedly connected to the first threaded portion and the second threaded portion, respectively. The adjusting member is connected to the adjusting shaft.

[0004] Although this reactor stirring mechanism can adjust the position of the stirring paddle inside the reactor, when the device is in use, the first stirring paddle and the second stirring paddle can stir and mix the liquid in the reactor. However, during stirring, the reactants tend to settle to the bottom plate of the reactor, resulting in uneven stirring of the materials. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a reaction vessel stirring device to solve the problem of uneven stirring of materials in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a reaction vessel stirring device, including a stirring shaft and a driving component. The stirring shaft is characterized by having a first connecting rod and a second connecting rod arranged radially thereon, the second connecting rod being located above the first connecting rod, and the length of the first connecting rod being less than that of the second connecting rod. It also includes a stirring plate capable of connecting the ends of the first and second connecting rods respectively, converging towards the bottom. Furthermore, the stirring shaft is provided with a connecting assembly capable of elastically displacing the first and second connecting rods along the axial direction of the stirring shaft.

[0007] By adopting the above technical solution, the stirring plates can be installed on the outside of the stirring shaft via the first and second connecting rods, and the stirring plates can be in a downward converging state. When the driving component drives the stirring shaft to rotate at high speed, the stirring plates can form a vortex, which can move the material on the upper side of the reactor to the lower side, thereby making the stirring more uniform. Furthermore, through the connecting components set on the stirring shaft, the stirring shaft can be moved back and forth in the vertical direction under the action of material pressure during rotation, causing the surface of the stirring plates to vibrate. This makes it less likely for the material to adhere to the surface of the stirring plates, and also makes the material mix more thoroughly, greatly improving the stirring efficiency of the material.

[0008] In one embodiment of the present invention, the first connecting rod and the second connecting rod are slidably connected to the stirring shaft in a vertical direction. The first connecting rod and the second connecting rod are not located in the same vertical plane, and the stirring plate is respectively connected to the ends of the first connecting rod and the second connecting rod.

[0009] By adopting the above technical solution, the orientation of the first connecting rod and the second connecting rod is such that the two connecting ends of the stirring plate are not located in the same vertical plane, which allows the stirring plate to be in an inclined state. This enables the stirring plate to achieve spiral conveying when it rotates, making it easier to convey the material from the upper side of the reactor to the bottom.

[0010] In one embodiment of this utility model, the stirring plate is configured as an arc-shaped stirring plate, and the two ends of the stirring plate are fixedly connected to the first connecting rod and the second connecting rod by fasteners respectively. There are two stirring plates, which are arranged opposite to each other on both sides of the stirring shaft, so that the two stirring plates form an inverted A-shaped structure.

[0011] By adopting the above technical solution, using an arc-shaped stirring plate, and making the two stirring plates form an A-shaped structure, a spiral conveying effect can be formed when rotating at high speed, resulting in better and more uniform stirring effect. Moreover, the stirring plates are installed using fasteners, which facilitates the installation of the stirring plates and subsequent maintenance.

[0012] In one embodiment of the present invention, the stirring shaft is a hollow shaft, and the side wall of the stirring shaft has a through groove for displacement of the first connecting rod and the second connecting rod. The connecting assembly includes a support rod disposed inside the stirring shaft, a connecting sleeve disposed on the first connecting rod and the second connecting rod respectively and capable of being sleeved on the support rod, and an elastic element sleeved on the support rod capable of elastically connecting the stirring shaft and the connecting sleeve. Both connecting sleeves are located in the through groove.

[0013] By adopting the above technical solution, the first connecting rod and the second connecting rod can be slidably connected to the support rod through the connecting sleeve, and then the connecting sleeve and the stirring plate can be elastically connected through the elastic element, so that the first connecting rod and the second connecting rod can move back and forth in the vertical direction, thereby causing the stirring plate to vibrate.

[0014] In one embodiment of the present invention, a fixing sleeve is coaxially arranged on the stirring shaft, and stirring blades are arranged on the side wall of the fixing sleeve. Multiple stirring blades are arranged around the axis of the fixing sleeve, and the stirring blades are inclined downward.

[0015] By adopting the above technical solution, and by setting multiple stirring blades on the stirring shaft, the material can be further stirred by the stirring blades. Moreover, by setting the stirring blades at an angle downward, an upward vortex can be generated, which, together with the stirring plate, achieves uniform stirring of the material on the upper and lower sides of the reactor.

[0016] In one embodiment of the present invention, a threaded post is provided at the end of the support rod, and a threaded hole is provided in the stirring shaft. The support rod is threadedly engaged with the stirring shaft, and a connecting cap that can fasten to the lower end of the stirring shaft is provided at the lower end of the support rod.

[0017] By adopting the above technical solution, the support column can be detachably installed inside the stirring shaft, which facilitates later maintenance. Both the first connecting rod and the second connecting rod can be detached from the stirring shaft, making it easier to transport and use.

[0018] In one embodiment of this utility model, two stirring blades are provided, and the stirring blades are arranged perpendicularly to the axis of the first connecting rod on the horizontal plane.

[0019] By adopting the above technical solution, the structure is simpler, and the mixing blades work in conjunction with the mixing plate to achieve cyclic conveying.

[0020] As described above, the reaction vessel stirring device of this utility model has the following beneficial effects: the stirring plate can be installed on the outside of the stirring shaft through the first connecting rod and the second connecting rod, and the stirring plate is in a downward convergence state. When the driving component drives the stirring shaft to rotate at high speed, the stirring plate forms a vortex, which allows the material on the upper side of the reaction vessel to move downward, thereby making the stirring more uniform. Furthermore, through the connecting component set on the stirring shaft, the stirring shaft can be moved back and forth in the vertical direction under the action of material pressure during rotation, causing the surface of the stirring plate to vibrate, which makes it less likely for the material to adhere to the surface of the stirring plate, and also makes the material mix more thoroughly, greatly improving the stirring efficiency of the material.

[0027] like Figure 1As shown, this utility model provides a reaction vessel stirring device, including a stirring shaft 1 and a driving component 2 as a power source to drive the stirring shaft 1 to rotate. The stirring shaft 1 is provided with a first connecting rod 3 and a second connecting rod 4 along its radial direction, and a stirring plate 5 connecting the ends of the first connecting rod 3 and the second connecting rod 4 respectively. The second connecting rod 4 is located above the first connecting rod 3, and the length of the first connecting rod 3 is less than that of the second connecting rod 4, so that the stirring plate 5 is gathered towards the bottom of the stirring shaft 1 and is in an inclined state. When the stirring shaft 1 is driven to rotate by the driving component 2, the material in the reaction vessel is stirred by the first connecting rod 3, the second connecting rod 4 and the stirring plate 5. The driving component 2 can be a drive motor.

[0028] The first connecting rod and the second connecting rod slide vertically to the stirring shaft 1. The center points of the first connecting rod 3 and the second connecting rod 4 coincide with the axis of the stirring shaft 1, and the first connecting rod and the second connecting rod are not located on the same vertical plane, so that the angle between the first connecting rod and the second connecting rod on the horizontal plane is 60°. The stirring plate 5 is connected to the ends of the first connecting rod and the second connecting rod respectively.

[0029] The stirring plate 5 is set as an arc-shaped stirring plate 5. Both ends of the stirring plate 5 are fixedly connected to the first connecting rod and the second connecting rod by fasteners respectively. There are two stirring plates 5, which are arranged opposite to each other on both sides of the stirring shaft 1, so that the two stirring plates 5 form an inverted A-shaped structure. The first connecting rod 3 and the second connecting rod 4 are staggered to make the stirring plates 5 arc-shaped and converge towards the bottom of the stirring shaft 1.

[0030] The stirring shaft 1 is a hollow shaft, and its side wall has a through groove 6 for displacement of the first connecting rod 3 and the second connecting rod 4, such as... Figure 2 As shown, the stirring shaft 1 is also provided with a connecting assembly 7 that can drive the first connecting rod 3 and the second connecting rod 4 to elastically displace along the axis of the stirring shaft 1. The connecting assembly 7 includes a support rod 8 disposed inside the stirring shaft 1, a connecting sleeve 9 disposed on the first connecting rod 3 and the second connecting rod 4 respectively and able to be sleeved on the support rod 8, and an elastic element 10 sleeved on the support rod 8 to elastically connect the stirring shaft 1 and the connecting sleeve 9. Both connecting sleeves 9 are located in the through groove 6. The elastic element 10 is a spring. Each connecting sleeve 9 has an elastic element 10 on its upper and lower sides that abuts against the side wall of the through groove 6, so that the first connecting rod 3 and the second connecting rod 4 can move back and forth in the vertical direction under the action of the elastic element 10.

[0031] The end of the support rod 8 is also provided with a threaded post 14, and a corresponding threaded hole is provided in the stirring shaft 1. The support rod 8 is threadedly engaged with the stirring shaft 1. The lower end of the support rod 8 is also provided with a connecting cover 11 that can fasten to the lower end of the stirring shaft 1. The side wall of the connecting cover 11 has a groove for easy screwing. The screwing direction of the support rod 8 is the same as the rotation direction of the stirring shaft 1. When the stirring shaft 1 rotates at high speed, the support rod 8 and the stirring shaft 1 are tightly engaged.

[0032] A fixing sleeve 12 is also coaxially arranged on the stirring shaft 1, and stirring blades 13 are arranged on the side wall of the fixing sleeve 12. There are two stirring blades 13 arranged around the axis of the fixing seat, and the stirring blades 13 are inclined downward. The stirring blades 13 are perpendicular to the axis of the first connecting rod 3 on the horizontal plane.

[0033] When the stirring shaft 1 rotates, it can drive the stirring blades 13 to rotate at high speed. By setting the direction of the stirring blades 13, an upward vortex is generated near the stirring shaft 1, which can transport the material at the bottom to the upper side. It can work with the stirring plate 5 to realize the circulation of the material on both the upper and lower sides, making the mixing more uniform.

[0034] In summary, this utility model enables the stirring plate 5 to be installed on the outside of the stirring shaft 1 via the first connecting rod 3 and the second connecting rod 4, and the stirring plate 5 to be in a downward convergent state. When the driving component 2 drives the stirring shaft 1 to rotate at high speed, the stirring plate 5 forms a vortex, which allows the material on the upper side of the reactor to move downward, thereby making the mixing more uniform. Furthermore, through the connecting component 7 set on the stirring shaft 1, the stirring shaft 1 can be moved back and forth in the vertical direction under the action of material pressure during rotation, causing the surface of the stirring plate 5 to vibrate, thus making it less likely for the material to adhere to the surface of the stirring plate 5, and also making the material mix more thoroughly, greatly improving the mixing efficiency of the material.

[0035] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
