Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and more specifically, to a vertical stirring structure for a reaction vessel. Background Technology
[0002] The stirring structure of reaction vessels is mostly in the form of a fixed stirring paddle. When it rotates, due to centrifugal force, a large amount of material will accumulate at the edge, making it difficult to mix quickly, thus affecting work efficiency. The working method is also relatively simple, and the function is also relatively limited.
[0003] To address the aforementioned issues, a vertical stirring structure for the reactor is proposed. Utility Model Content
[0004] To solve the above-mentioned technical problems, a vertical stirring structure for a reaction vessel is provided. This technical solution solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention can be implemented using the following technical solutions:
[0006] This utility model provides a vertical stirring structure for a reaction vessel, including a reaction vessel and a stirring assembly. The stirring assembly includes a main shaft installed at the top center of the reaction vessel and two independent cavities separated by a partition inside the main shaft.
[0007] The stirring assembly also includes multiple support arms evenly installed around the bottom of the main shaft. Each support arm has a transition bend installed at one end. The bottom of each independent cavity is connected to a guide pipe. One end of each guide pipe is connected to the opposite opening of two adjacent transition bends. Rotary pipes are provided in the gaps between the remaining adjacent transition bends. The two ends of each rotary pipe are rotatably connected to the ports of the transition bends. Deflection blades are provided inside each rotary pipe. Blades are provided around the outside of each rotary pipe. One side of each blade is rotatably connected to the outside of the rotary pipe via a vertical shaft. Limiting pin one and limiting pin two are respectively provided on the surface of the rotary pipe on both sides of the middle part of the blade.
[0008] When the blade is in contact with the first limiting pin, the blade and the rotating tube are aligned in the same axial direction. When the blade is in contact with the second limiting pin, the blade and the rotating tube have a certain angle.
[0009] Furthermore, it also includes a cooling assembly, which includes a jacket fitted around the outside of the reactor and a coil wound between the reactor and the jacket;
[0010] One side of the coil is attached to the reactor vessel, and the other side is attached to the jacket. A spiral upward gap is formed between the coil and the jacket.
[0011] Furthermore, the coil has a semi-circular cross-section, with its straight side fitting into the reactor and its arc side fitting into the jacket.
[0012] Furthermore, the cooling assembly also includes an inlet pipe connected to the bottom end of the tube gap, an outlet pipe connected to the top end of the tube gap, and a three-way valve II connected to the outlet pipe;
[0013] The remaining two valve ports of the three-way valve are respectively connected to the top ends of the two independent cavities.
[0014] Furthermore, the cooling assembly also includes a three-way valve, the two valve ports of which are respectively connected to the top ends of the two independent cavities.
[0015] Furthermore, the cooling assembly also includes a gas storage cylinder, the outlet of which is connected to the inlet pipe.
[0016] Furthermore, the cooling assembly also includes an air compressor, the air outlet of which is connected to the air inlet of the air storage cylinder.
[0017] As described above, the features and advantages of the vertical stirring structure of the reaction vessel in this utility model are:
[0018] When the blades are in contact with the first limiting pin, the axial direction of the blades and the rotating tube is aligned, allowing the rotating blades to stir vertically. When the blades are in contact with the second limiting pin, the axial direction of the blades and the rotating tube is at a certain angle, making the rotating blades resemble a propeller and driving the material to flow horizontally, thus achieving horizontal stirring. Both stirring methods can be achieved by selecting the forward and reverse flow of air inside the stirring assembly using three-way valves one and two. This dual-mode stirring makes mixing more efficient and avoids material accumulation at the edges. Furthermore, the air flowing into the stirring assembly, when cooled, can also help cool the reactor, improving ease of use. Attached Figure Description

[0029] See 1~ Figure 8 As shown in the figure, a vertical stirring structure for a reaction vessel provided by this utility model will be described in detail below:
[0030] A vertical stirring structure for a reactor includes a reactor 1 and a stirring assembly 3. The stirring assembly 3 includes a main shaft 301 installed at the top center of the reactor 1 and two independent cavities 302 separated by a partition inside the main shaft 301 to facilitate gas reflux and selection of forward and reverse flow.
[0031] The stirring assembly 3 also includes multiple support arms 303 evenly installed around the bottom of the main shaft 301. Each support arm 303 has a transition bend 304 installed at one end. Each independent cavity 302 has a guide pipe 305 connected to its bottom. One end of the guide pipe 305 is connected to the opposite opening of two adjacent transition bends 304 respectively. Rotary tubes 306 are provided in the gaps between the remaining adjacent transition bends 304. The two ends of the rotary tubes 306 are rotatably connected to the ports of the transition bends 304. The interior of the rotary tubes 306 is provided with deflecting blades 307. The exterior of the rotary tubes 306 is provided with blades 308. One side of the blades 308 is rotatably connected to the exterior of the rotary tubes 306 via a vertical shaft. Limiting pin 1 309 and limiting pin 2 310 are respectively provided on both sides of the middle part of the rotary tubes 306.
[0032] In this embodiment, when the airflow is flowing, the rotating tube 306 is rotated by impacting the deflecting blade 307, and then the blade 308 rotates accordingly to achieve the purpose of stirring.
[0033] When the blade 308 is in contact with the first limiting pin 309, the axial direction of the blade 308 is consistent with that of the rotating tube 306. When the blade 308 is in contact with the second limiting pin 310, the axial direction of the blade 308 and the rotating tube 306 has a certain angle.
[0034] Furthermore, it also includes a cooling assembly 2, which includes a jacket 201 fitted outside the reactor 1 and a coil 202 coiled between the reactor 1 and the jacket 201.
[0035] One side of the coil 202 is attached to the reactor 1, and the other side is attached to the jacket 201. A spiral upward gap 203 is formed between the coil 202 and the jacket 201.
[0036] Furthermore, the cross-section of the coil 202 is semi-circular, with its straight side attached to the reactor 1 and its arc side attached to the jacket 201.
[0037] Furthermore, the cooling assembly 2 also includes an inlet pipe 204 connected to the bottom end of the pipe gap 203, an outlet pipe 205 connected to the top end of the pipe gap 203, and a three-way valve 209 connected to the outlet pipe 205.
[0038] Among them, the remaining two valve ports of the three-way valve 209 are respectively connected to the top of the two independent cavities 302.
[0039] Furthermore, the cooling assembly 2 also includes a three-way valve 208, the two valve ports of which are respectively connected to the top ends of two independent cavities 302.
[0040] Furthermore, the cooling assembly 2 also includes a gas storage cylinder 207, the outlet of which is connected to the inlet pipe 204.
[0041] Furthermore, the cooling assembly 2 also includes an air compressor 206, the air outlet of which is connected to the air inlet of the air storage cylinder 207.
[0042] In this embodiment, the use of a pneumatically driven stirring paddle has several advantages. First, the gas source can be located at a distance, thereby avoiding the howling noise of motor-driven paddles in the prior art and improving the comfort of the working environment. Second, one gas source can drive multiple reaction vessels without the need for a complex mechanical transmission structure. Third, the gas can be cooled, thereby assisting in temperature control during the reaction.
[0043] Based on the above embodiments, the following is the complete working process and working principle of the above embodiments:
[0044] The operating state is as follows: The reactor is operated in an orderly manner according to the general operating procedures. Cooling water flows upwards through coil 202 to cool the interior of reactor 1. The three-way valve 209 is activated to introduce high-pressure air from gas cylinder 207 into pipe gap 203, where it is cooled by the cooling water. The air then enters one of the independent chambers 302 inside the main shaft 301 via the three-way valve 209. Guided by the independent chamber 302, this air flows through one of the guide pipes 305 into transition bend 304, then flows through transition bend 304 and rotating pipe 306, and returns to another independent chamber 302 via another guide pipe 305. Finally, it is discharged to the outside by three-way valve 208. During the airflow, the rotating pipe 306 rotates by impacting the deflector blades 307. At this time, the limit pin 309 or the limit... The impeller 308 rotates under the limiting pin 310. When the impeller 308 is in contact with the limiting pin 309, the axial direction of the impeller 308 is consistent with that of the rotating tube 306. At this time, the rotating impeller 308 can achieve vertical stirring. When the impeller 308 is in contact with the limiting pin 310, the axial direction of the impeller 308 and the rotating tube 306 has a certain angle. At this time, the rotating impeller 308 is like a propeller, which can drive the material to flow horizontally, thereby achieving horizontal stirring. The above two stirring methods can be achieved by selecting the forward and reverse flow of air inside the stirring assembly 3 through the three-way valve 208 and the three-way valve 209. The dual-mode stirring makes the stirring and mixing more efficient. In addition, when the air flowing into the stirring assembly 3 is cooled, it can also help to cool down when it flows into the reactor 1, improving the convenience of use.
[0045] The above description is merely an embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
