Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a dead-zone-free stirred reaction vessel. Background Technology

[0002] In many industrial fields such as chemical, pharmaceutical, and food, stirred reactors are core equipment for material mixing and chemical reactions. Their performance directly affects important aspects such as production efficiency, product quality, and production safety. With the continuous development of industrial production, higher requirements have been placed on the stirring effect, ease of cleaning, and sealing performance of stirred reactors.

[0003] In terms of cleaning reactors, traditional stirred reactors often require manual cleaning of the inner cavity. Manual cleaning not only consumes a lot of time and labor costs, but also makes it difficult to completely remove residual raw materials for some complex reactors, which can easily cause cross-contamination. At the same time, during the manual cleaning process, operators may come into contact with corrosive or toxic raw materials, which poses certain safety risks.

[0004] Furthermore, the existing connection structure between the feed pipe and the sealing cap of the stirred reactor is prone to loosening during long-term use due to factors such as vibration and pressure changes. A loose sealing cap leads to air leakage from the feed pipe, causing not only material waste but also potential pressure instability within the reactor, adversely affecting the reaction process and even causing safety accidents. Therefore, we propose a dead-zone-free stirred reactor. Utility Model Content

[0005] The purpose of this invention is to provide a dead-zone-free stirred reactor to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a dead-zone-free stirred reactor, comprising:

[0007] A reaction vessel, wherein a stirring rod 1 and four stirring rods 2 are rotatably installed inside the reaction vessel, and the four stirring rods 2 are all located around the stirring rod 1;

[0008] A drive assembly, located inside the reactor, is used to drive stirring rod one and four stirring rods two to reciprocate.

[0009] An annular tube is fixedly installed at the top of the inner cavity of the reactor. Several nozzles are fixedly installed at the bottom of the annular tube. A water pump is fixedly installed at the top of the reactor. A connecting pipe is fixedly installed at the outlet end of the water pump. The bottom end of the connecting pipe is fixed to the annular tube. An inlet pipe is fixedly installed at the inlet end of the water pump. A feed pipe is fixedly installed at the top of the reactor. A sealing cap is threaded onto the top end of the feed pipe. A sealing gasket is fixedly installed inside the sealing cap.

[0010] A limiting component is located on the reactor and is used to limit the sealing cap.

[0011] In this technical solution, during use, the operator can drive the stirring rod one and the four stirring rods two to rotate back and forth through the drive component. Under the action of the reciprocating rotation of the stirring rod one and the four stirring rods two, the raw materials in the reactor can be fully stirred without dead angles. Moreover, the reciprocating rotation will cause the raw materials to form complex three-dimensional turbulence, reduce stirring dead angles, and avoid local accumulation or stratification.

[0012] After the reaction is complete, personnel can connect one end of the inlet pipe to a water source and start the water pump. The water pump can draw water into the pump through the inlet pipe and deliver it to the connecting pipe. The water in the connecting pipe will enter the annular pipe and finally be sprayed out through several nozzles. The water sprayed from the nozzles can rinse the inner cavity of the reactor, thereby achieving a self-cleaning effect. It does not require manual cleaning by personnel, which is convenient and quick.

[0013] During use, the operator can screw the sealing cap onto the feed pipe until the sealing gasket inside the sealing cap is against the top of the feed pipe. At this point, the sealing gasket can seal the feed pipe. Then, the operator can use the limiting component to limit the sealing cap to prevent it from becoming loose, ensuring that the feed pipe will not leak air due to a loose sealing cap. This enhances the sealing performance of the feed pipe and prevents raw material leakage and waste.

[0014] In the above technical solution, the driving component further includes:

[0015] A rotating trough is formed inside the reactor and located above the stirring rod 1. A gear 1 is rotatably installed inside the rotating trough. The bottom end of the gear 1 passes through the bottom of the rotating trough and is coaxially connected to the stirring rod. Four gears 2 are meshed around the gear 1 and located inside the rotating trough. The bottom ends of the four gears 2 all pass through the bottom of the rotating trough and are coaxially connected to the four stirring rods 2 respectively.

[0016] The movable tank is located inside the reactor and above the rotating tank. A gear three is rotatably installed inside the movable tank. The bottom end of the gear three penetrates the bottom of the movable tank and is coaxially connected with the gear. A rack is meshed with one side of the gear three and located inside the movable tank. An electric push rod is fixedly installed inside the movable tank and located at one end of the rack. The output end of the electric push rod is fixed to the rack.

[0017] In this technical solution, personnel can activate an electric push rod. The output shaft of the electric push rod drives a rack to reciprocate. Under meshing action, the reciprocating movement of the rack drives gear three to reciprocate. The reciprocating rotation of gear three drives gear one to reciprocate. Under meshing action, the reciprocating rotation of gear one drives four gear twos to reciprocate. The reciprocating rotation of the four gear twos drives four stirring rods two to reciprocate. At the same time, the reciprocating rotation of gear one also drives stirring rod one to reciprocate. Under the action of stirring rod one and the four stirring rods two, the raw materials in the reactor can be thoroughly stirred without dead angles. Moreover, the reciprocating rotation will cause the raw materials to form complex three-dimensional turbulence, reducing stirring dead angles and avoiding local accumulation or stratification.

[0018] In the above technical solution, the second gear is rotatably connected to the rotating groove, the rack is slidably connected to the movable groove, and the output shaft of the electric push rod is slidably connected to the movable groove.

[0019] In this technical solution, it is ensured that gear two can rotate normally in the rotating groove, that the rack can slide normally in the movable groove, and that the output shaft of the electric push rod can slide normally in the movable groove.

[0020] In the above technical solution, the limiting component further includes:

[0021] A rectangular plate is fixedly installed on the top of the reactor and located on one side of the sealing cover. Several slots are provided on the periphery of the sealing cover. A threaded rod is threadedly installed on the rectangular plate. A pressing plate is rotatably installed on one end of the threaded rod. Several protrusions are fixedly installed on the inner side of the pressing plate. Limiting rods are fixedly installed on the outer side of the pressing plate and on both sides of the threaded rod. One end of the limiting rod penetrates through the rectangular plate.

[0022] In this technical solution, during use, the operator can screw the sealing cap onto the feed pipe until the sealing gasket inside the sealing cap abuts against the top of the feed pipe. At this point, the sealing gasket can seal the feed pipe. Subsequently, the operator can rotate the threaded rod. Under the action of the thread, the rotation of the threaded rod will drive the extrusion plate to move. At the same time, the two limiting rods will slide within the rectangular plate. Under the limiting action of the two limiting rods, the extrusion plate can be prevented from rotating until several protrusions on the inner side of the extrusion plate are engaged in the corresponding slots. At this point, the protrusions can limit the sealing cap, preventing the sealing cap from becoming loose and ensuring that the feed pipe will not leak air due to the sealing cap becoming loose. This enhances the sealing performance of the feed pipe and avoids the waste of raw materials due to leakage.

[0023] In the above technical solution, the protrusion engages with the slot, the limiting rod slides with the rectangular plate, and the slots are distributed in a ring at equal intervals.

[0024] In this technical solution, it is ensured that the protrusion can be engaged in the slot, the limiting rod can slide normally within the rectangular plate, and the distribution of the slots is uniform.

[0025] In the above technical solution, a discharge pipe is fixedly installed at the bottom of the reactor, and a valve is rotatably installed on the discharge pipe.

[0026] In this technical solution, it is ensured that personnel can open the valve so that the material inside the reactor can be discharged through the discharge pipe.

[0027] In the above technical solution, the four stirring rods are arranged in a ring with equal spacing, the nozzles are arranged in a ring with equal spacing, and the sealing gasket is in close contact with the top of the feed pipe.

[0028] In this technical solution, it is ensured that the four stirring rods can stir the inner cavity of the reactor without dead angles, that the water sprayed from the nozzles can be more uniform, and that the sealing gasket can seal the feed pipe.

[0029] In the above technical solution, the connecting pipe is further connected to the annular pipe.

[0030] In this technical solution, it is ensured that water in the connecting pipe can enter the annular pipe.

[0031] The beneficial effects of this utility model are:

[0032] 1. This dead-zone-free stirred reactor, through the set drive component, with the cooperation of the drive component, stirring rod one and stirring rod two, can fully stir the raw materials in the reactor without dead zones, and the reciprocating rotation will make the raw materials form complex three-dimensional turbulence, reduce stirring dead zones, and avoid local accumulation or stratification.

[0033] 2. This dead-zone-free stirred reactor, through the coordinated action of a water pump, inlet pipe, connecting pipe, annular pipe, nozzle, sealing cap, sealing gasket, and limiting components, can flush the inner cavity of the reactor, achieving a self-cleaning effect. It eliminates the need for manual cleaning, making it convenient and quick. It also ensures that the feed pipe will not leak due to a loose sealing cap, enhancing the sealing performance of the feed pipe and preventing raw material leakage and waste.

[0043] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0044] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0045] Example 1: This example provides a dead-zone-free stirred reactor, comprising:

[0046] The reactor 1 is equipped with a stirring rod 2 and four stirring rods 3, which are rotatably installed inside the reactor 1. All four stirring rods 3 are located around the stirring rod 2.

[0047] The drive assembly is located inside the reactor 1 and is used to drive the first stirring rod 2 and the four second stirring rods 3 to reciprocate.

[0048] An annular pipe 11 is fixedly installed at the top of the inner cavity of the reactor 1. Several nozzles 12 are fixedly installed at the bottom of the annular pipe 11. A water pump 14 is fixedly installed at the top of the reactor 1. A connecting pipe 13 is fixedly installed at the outlet end of the water pump 14. The bottom end of the connecting pipe 13 is fixed to the annular pipe 11. An inlet pipe 15 is fixedly installed at the inlet end of the water pump 14. A feed pipe 16 is fixedly installed at the top of the reactor 1. A sealing cap 17 is threaded onto the top end of the feed pipe 16. A sealing gasket 18 is fixedly installed inside the sealing cap 17.

[0049] A limiting component is located on the reactor 1 and is used to limit the sealing cover 17.

[0050] In use, personnel can drive the stirring rod 1 2 and the four stirring rods 2 3 to reciprocate. Under the action of the reciprocating rotation of the stirring rod 1 2 and the four stirring rods 2 3, the raw materials in the reactor 1 can be fully stirred without dead angles. Moreover, the reciprocating rotation will cause the raw materials to form complex three-dimensional turbulence, reduce stirring dead angles, and avoid local accumulation or stratification.

[0051] After the reaction is complete, personnel can connect one end of the water inlet pipe 15 to a water source and then start the water pump 14. The water pump 14 can draw water into the water pump 14 through the water inlet pipe 15 and deliver it to the connecting pipe 13. The water in the connecting pipe 13 will enter the annular pipe 11 and finally be sprayed out through several nozzles 12. The water sprayed out by the several nozzles 12 can rinse the inner cavity of the reaction vessel 1, thereby achieving a self-cleaning effect. It does not require manual cleaning by personnel, which is more convenient and faster.

[0052] During use, the operator can screw the sealing cap 17 onto the feed pipe 16 until the sealing gasket 18 inside the sealing cap 17 abuts against the top of the feed pipe 16. At this time, the sealing gasket 18 can seal the feed pipe 16. Then, the operator can limit the sealing cap 17 through the limiting component to prevent the sealing cap 17 from becoming loose, ensuring that the feed pipe 16 will not leak air due to the sealing cap 17 becoming loose. This can enhance the sealing performance of the feed pipe 16 and prevent the leakage and waste of raw materials.

[0053] Example 2: This example provides a dead-zone-free stirred reactor, which, in addition to the technical solutions of the above examples, also has the following technical features, including a drive assembly comprising:

[0054] Rotating groove 4 is located inside the reactor 1 and above stirring rod 2. Gear 5 is rotatably installed inside rotating groove 4. The bottom end of gear 5 passes through the bottom of rotating groove 4 and is coaxially connected to stirring rod 2. Four gears 6 are meshed around gear 5 and inside rotating groove 4. The bottom ends of the four gears 6 all pass through the bottom of rotating groove 4 and are coaxially connected to four stirring rods 3 respectively.

[0055] The movable tank 7 is located inside the reactor 1 and above the rotating tank 4. A gear 3 8 is rotatably installed inside the movable tank 7. The bottom end of the gear 3 8 passes through the bottom of the movable tank 7 and is coaxially connected with the gear 1 5. A rack 9 is meshed with one side of the gear 3 8 and inside the movable tank 7. An electric push rod 10 is fixedly installed inside the movable tank 7 and at one end of the rack 9. The output end of the electric push rod 10 is fixed to the rack 9.

[0056] The system allows personnel to activate the electric push rod 10. The output shaft of the electric push rod 10 drives the rack 9 to reciprocate. Under meshing action, the reciprocating movement of the rack 9 drives the gear 3 8 to reciprocate. The reciprocating rotation of the gear 3 8 drives the gear 1 5 to reciprocate. Under meshing action, the reciprocating rotation of the gear 1 5 drives the four gears 2 6 to reciprocate. The reciprocating rotation of the four gears 2 6 drives the four stirring rods 2 3 to reciprocate. At the same time, the reciprocating rotation of the gear 1 5 also drives the stirring rod 1 2 to reciprocate. Under the action of the reciprocating rotation of the stirring rod 1 2 and the four stirring rods 2 3, the raw materials in the reactor 1 can be thoroughly stirred without dead angles. Moreover, the reciprocating rotation will cause the raw materials to form complex three-dimensional turbulence, reducing the stirring dead angles and avoiding local accumulation or stratification.

[0057] Example 3: This example provides a dead-zone-free stirred reactor. In addition to the technical solutions of the above examples, it also has the following technical features: gear 6 is rotatably connected to the rotating groove 4, rack 9 is slidably connected to the movable groove 7, and the output shaft of electric push rod 10 is slidably connected to the movable groove 7.

[0058] Specifically, it ensures that gear 6 can rotate normally in the rotating groove 4, that rack 9 can slide normally in the movable groove 7, and that the output shaft of electric push rod 10 can slide normally in the movable groove 7.

[0059] Example 4: This example provides a dead-zone-free stirred reactor, which, in addition to the technical solutions of the above examples, also has the following technical features, including a limiting component:

[0060] A rectangular plate 20 is fixedly installed on the top of the reactor 1 and located on one side of the sealing cover 17. Several slots 19 are provided on the periphery of the sealing cover 17. A threaded rod 21 is threadedly installed on the rectangular plate 20. A pressing plate 22 is rotatably installed on one end of the threaded rod 21. Several protrusions 23 are fixedly installed on the inner side of the pressing plate 22. Limiting rods 24 are fixedly installed on the outer side of the pressing plate 22 and on both sides of the threaded rod 21. One end of the limiting rod 24 passes through the rectangular plate 20.

[0061] In use, the operator can screw the sealing cap 17 onto the feed pipe 16 until the sealing gasket 18 inside the sealing cap 17 abuts against the top of the feed pipe 16. At this time, the sealing gasket 18 can seal the feed pipe 16. Then, the operator can rotate the threaded rod 21. Under the action of the thread, the rotation of the threaded rod 21 will drive the extrusion plate 22 to move. At the same time, the two limiting rods 24 will slide within the rectangular plate 20. Under the limiting action of the two limiting rods 24, the extrusion plate 22 can be prevented from rotating until the several protrusions 23 on the inner side of the extrusion plate 22 are engaged into the corresponding slots 19. At this time, the several protrusions 23 can limit the sealing cap 17, preventing the sealing cap 17 from becoming loose. This ensures that the feed pipe 16 will not leak air due to the loose sealing cap 17, which can enhance the sealing performance of the feed pipe 16 and avoid raw material leakage and waste.

[0062] Example 5: This example provides a dead-zone-free stirred reactor. In addition to the technical solutions of the above examples, it also has the following technical features: the protrusion 23 is engaged with the slot 19, the limiting rod 24 is slidably connected to the rectangular plate 20, and a number of slots 19 are distributed in a ring at equal intervals.

[0063] In this process, it is ensured that the protrusion 23 can be inserted into the slot 19, that the limiting rod 24 can slide normally within the rectangular plate 20, and that the distribution of the slots 19 is uniform.

[0064] Example 6: This example provides a dead-zone-free stirred reactor. In addition to the technical solutions of the above examples, it also has the following technical features: a discharge pipe 25 is fixedly installed at the bottom of the reactor 1, and a valve is rotatably installed on the discharge pipe 25.

[0065] This includes ensuring that personnel can open the valves so that the material inside the reactor 1 can be discharged through the discharge pipe 25.

[0066] Example 7: This example provides a dead-zone-free stirred reactor. In addition to the technical solutions of the above examples, it also has the following technical features: four stirring rods 3 are distributed in a ring at equal intervals, several nozzles 12 are distributed in a ring at equal intervals, and the sealing gasket 18 is in close contact with the top of the feed pipe 16.

[0067] Among these measures, it is ensured that the four stirring rods 2 3 can stir the inner cavity of the reactor 1 without dead angles, that the water sprayed from the nozzles 12 can be more even, and that the sealing gasket 18 can seal the feed pipe 16.

[0068] Example 8: This example provides a dead-zone-free stirred reactor, which, in addition to the technical solutions of the above examples, also has the following technical features: the connecting pipe 13 is connected to the annular pipe 11.

[0069] This ensures that the water in the connecting pipe 13 can enter the annular pipe 11.

[0070] Working principle: During use, the operator can start the electric push rod 10. The output shaft of the electric push rod 10 will drive the rack 9 to move back and forth. Under the action of meshing, the reciprocating movement of the rack 9 will drive the gear 3 8 to rotate back and forth. The reciprocating rotation of the gear 3 8 will drive the gear 1 5 to rotate back and forth. Under the action of meshing, the reciprocating rotation of the gear 1 5 will drive the four gears 2 6 to rotate back and forth. The reciprocating rotation of the four gears 2 6 will drive the four stirring rods 2 3 to rotate back and forth. At the same time, the reciprocating rotation of the gear 1 5 will also drive the stirring rod 1 2 to rotate back and forth. Under the action of the reciprocating rotation of the stirring rod 1 2 and the four stirring rods 2 3, the raw materials in the reactor 1 can be thoroughly stirred without dead angles. Moreover, the reciprocating rotation will make the raw materials form complex three-dimensional turbulence, reduce the stirring dead angles, and avoid local accumulation or stratification.

[0071] After the reaction is complete, personnel can open the valve to allow the material in the reactor 1 to be discharged through the discharge pipe 25. Then, personnel can connect one end of the water inlet pipe 15 to a water source and start the water pump 14. The water pump 14 can draw water into the water pump 14 through the water inlet pipe 15 and deliver it to the connecting pipe 13. The water in the connecting pipe 13 will enter the annular pipe 11 and finally be sprayed out through several nozzles 12. The water sprayed from the several nozzles 12 can rinse the inner cavity of the reactor 1, thereby achieving a self-cleaning effect. It does not require manual cleaning by personnel and is more convenient and quick.

[0072] During use, the operator can screw the sealing cap 17 onto the feed pipe 16 until the sealing gasket 18 inside the sealing cap 17 abuts against the top of the feed pipe 16. At this time, the sealing gasket 18 can seal the feed pipe 16. Then, the operator can rotate the threaded rod 21. Under the action of the thread, the rotation of the threaded rod 21 will drive the extrusion plate 22 to move. At the same time, the two limiting rods 24 will slide within the rectangular plate 20. Under the limiting action of the two limiting rods 24, the extrusion plate 22 can be prevented from rotating until the several protrusions 23 on the inner side of the extrusion plate 22 are engaged in the corresponding slots 19. At this time, the several protrusions 23 can limit the sealing cap 17, preventing the sealing cap 17 from becoming loose. This ensures that the feed pipe 16 will not leak air due to the loose sealing cap 17, which can enhance the sealing performance of the feed pipe 16 and prevent raw material leakage and waste.
