[0002] A reaction vessel is a device used for carrying out chemical reactions, and it usually consists of a vessel body, a stirrer, a heating device, a cooling device, etc.
[0003] As a core component for transmitting power and torque, the stirring shaft of the reactor is subjected to complex mechanical stress and harsh chemical environment for a long time. After a certain period of use, it needs to be maintained and replaced. However, traditional stirring shafts are mostly assembled with fasteners, which requires not only pulling out the shaft body but also disassembling and assembling the fasteners, which is not conducive to quick replacement and maintenance. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reaction vessel with a quickly replaceable stirring shaft.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A limit stop is fitted on the outer side of the locking ring. Multiple conical clips are installed on the inner wall of the limit stop. The other end of the conical clip passes through the locking ring and engages with multiple stop strips provided on the outer wall of the drive sleeve.
[0008] A connecting sleeve is fixedly installed on the upper part of the stirring shaft. The connecting sleeve has a thread in the middle and a conical plug at the top. A connecting block is installed in the middle of the conical plug. The conical plug is inserted into the mating groove opened in the middle of the driving sleeve.

[0010] Furthermore, in a preferred configuration, the docking groove has an internal groove that fits into the connecting block.
[0011] In addition, a preferred structure is that the bottom wall of the drive sleeve is equipped with a rubber pad with raised strips, and when the stirring shaft is connected to the drive sleeve, the rubber pad with raised strips is pressed into contact with the upper wall of the connecting sleeve.
[0012] Furthermore, in a preferred configuration, when the conical plug is inserted into the mating groove, a gap is left between the top wall of the conical plug and the top wall of the mating groove.
[0013] In addition, a preferred structure is that the outer wall of the drive sleeve is provided with a ring array of multiple baffles, with gaps between adjacent baffles to engage the conical card.
[0014] In addition, a preferred structure is that the outer wall of the locking ring is provided with multiple limiting grooves, and a conical card is installed in the limiting groove, and the conical card is connected to the limiting groove by a spring.
[0015] The beneficial effects of this utility model are as follows:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Reference Figure 1-6 A reaction vessel with a quick-change stirring shaft includes a vessel body 1, a cover 2 on the upper part of the vessel body 1, a drive sleeve 5 installed at the bottom of the cover 2, the drive sleeve 5 being driven to rotate by a drive motor 3, and a stirring shaft 4 installed in the middle of the drive sleeve 5.
[0026] A locking ring 6 is rotatably mounted on the outer wall of the drive sleeve 5. The bottom inner wall of the locking ring 6 is threaded. A limit stop 61 is sleeved on the outer side of the locking ring 6. Multiple conical clips 62 are mounted on the inner wall of the limit stop 61. The other end of the conical clip 62 passes through the locking ring 6 and engages with multiple stop strips 51 provided on the outer wall of the drive sleeve 5.
[0027] A connecting sleeve 41 is fixedly installed on the upper part of the stirring shaft 4. The middle part of the connecting sleeve 41 is threaded, and the connecting sleeve 41 and the bottom inner wall thread of the locking ring 6 form a threaded connection mechanism.
[0028] A tapered plug 42 is provided at the upper middle part of the connecting sleeve 41, and a connecting block 43 is installed in the middle of the tapered plug 42. The tapered plug 42 is inserted into the mating groove 7 opened in the middle of the drive sleeve 5.
[0029] Connector 43 is used to transmit motor power, which is easy to understand intuitively and will not be explained further.
[0030] A drive motor 3 is installed on the upper part of the cover 2. The output end of the drive motor 3 is connected to a drive sleeve 5, and the drive motor 3 drives the drive sleeve 5 to rotate.
[0031] The inside of the docking groove 7 is provided with a groove that fits into the connecting block 43.
[0032] The bottom wall of the drive sleeve 5 is equipped with a rubber pad 52 with raised strips. When the stirring shaft 4 is connected to the drive sleeve 5, the rubber pad 52 with raised strips is pressed against the upper wall of the connecting sleeve 41.
[0033] The bottom wall of the rubber pad 52 has a ring array of multiple raised strips that deform when compressed.
[0034] When the conical plug 42 is inserted into the mating groove 7, there is a gap between the top wall of the conical plug 42 and the top wall of the mating groove 7.
[0035] The outer wall of the drive sleeve 5 is provided with a ring array of multiple baffles 51, with gaps between adjacent baffles 51 to engage the conical card 62.
[0036] The outer wall of the locking ring 6 is provided with multiple limiting grooves 8, and a conical card 62 is installed in the limiting groove 8. The conical card 62 is connected to the limiting groove 8 by a spring 9.
[0037] The upper end of the tapered card 62 is tapered to improve the engagement efficiency with the stop bar 51.
[0038] In this embodiment, during the disassembly of the stirring shaft 4, the limiting baffle 61 on the outer wall of the locking ring 6 is pressed down, causing the conical clip 62 to disengage from the slot of the baffle 51 on the outer wall of the drive sleeve 5. Then, the locking ring 6 is rotated to generate a threaded rotation with the connecting sleeve 41 on the stirring shaft 4 until the connecting sleeve 41 moves downward and disengages from the locking ring 6, and the two no longer have a threaded connection. Then, the stirring shaft 4 is pulled out, so that the conical plug 42 disengages from the docking groove 7 to complete the disassembly.
[0039] Conversely, during the installation of the stirring shaft 4, the tapered plug 42 and connecting block 43 on the upper part of the connecting sleeve 41 are aligned with the docking groove 7 in the middle of the drive sleeve 5 and inserted for connection. Then, the stirring shaft 4 is pushed up appropriately so that the upper wall of the connecting sleeve 41 is pressed into contact with the bottom wall of the rubber pad 52 with convex strips, and the rubber pad 52 with convex strips undergoes corresponding deformation.
[0040] At the same time, the top thread of the connecting sleeve 4 is connected to the bottom thread of the locking ring 6. At this time, the locking ring 6 is unlocked by pressing down the limiting baffle 61, and the locking ring 6 is rotated synchronously to drive the connecting sleeve 41 upward through the spiral rotation until the threaded connection is completed. Then, the locking ring 6 is continuously rotated to tighten the connection between the connecting sleeve 41 and the driving sleeve 5. When it is manually tightened, the stirring shaft 4 and the driving sleeve 5 are fully connected and meet the operation rotation requirements. At this time, the limiting baffle 61 is released, and the conical card 62 is driven upward by the return action of the spring 9 to re-lock into the baffle 51, thereby locking the rotation function of the locking ring 6.
[0041] In practical applications, the secondary deflection locking ring 6 can ensure that the conical card 62 and the stop bar 51 are locked in place. The rubber pad 5 with the convex strip can adapt to deformation due to its rubber material properties to fit the connecting sleeve 41.
[0042] During the replacement of the stirring shaft of the reactor, it is necessary to disassemble the cover 2;
[0043] The cover 2 is a standard configuration of the vessel body 1, and the specific disassembly method is common knowledge to those skilled in the art and will not be explained further.
[0044] Among them, vessel body 1, namely the reactor vessel body, the specific reaction operation principle, process and components of the reactor not described above are all conventional configurations and are common knowledge to those skilled in the art, and will not be explained further.
[0045] 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.
