Description

Technical Field

[0001] This utility model relates to the technical field of reaction vessels, specifically to an adjustable reaction vessel stirring mechanism and a reaction vessel. Background Technology

[0002] A reaction vessel is a device used for chemical reactions, commonly used in industrial production. It is a closed container with a stirring device inside, which can control the temperature, pressure, and mixing of reactants to promote the chemical reaction. It is widely used in industries such as petrochemicals, pharmaceuticals, food processing, coatings, and dyes for processes such as synthesis, polymerization, and fermentation.

[0003] The existing stirring mechanism in the reactor is generally a rotating rod that drives the stirring blade to rotate for stirring. The stirring effect is poor. When stirring different raw materials, uneven stirring, low stirring efficiency and large losses are likely to occur. Therefore, we designed an adjustable stirring mechanism and reactor. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable stirring mechanism and a reactor, which can adjust the position and angle of the stirring rod to change the stirring range and stirring loss, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable reaction vessel stirring mechanism, comprising a support frame, a first clamping plate fixedly connected to the outer side of the support frame, a first rotating rod movably connected between the first clamping plates, a first stirring rod also provided outside the support frame, one end of the first stirring rod movably connected to the outer side of the first rotating rod, a sliding frame movably connected to the outer side of the support frame, a second clamping plate fixedly connected to the outer side of the sliding frame, a second rotating rod movably connected between the second clamping plates, one end of the second stirring rod fixedly connected to the outer side of the second rotating rod, and the other end of the second stirring rod movably connected to the end of the first stirring rod away from the support frame via a hinge.

[0006] A threaded rod is provided inside the support frame, and a servo motor is fixedly installed on the inner top wall of the support frame. The output end of the servo motor is fixedly connected to the top end of the threaded rod. A movable ring is movably connected to the outer side of the threaded rod. A strip-shaped hole is opened on the support frame, and a fixed rod is fixedly connected to the outer side of the movable ring. The end of the fixed rod away from the movable ring is slidably connected in the strip-shaped hole and fixedly connected to the sliding frame.

[0007] Through the above technical solution, this application starts the servo motor to drive the threaded rod to rotate. At this time, the moving ring is limited by the fixed rod and moves up and down, that is, the sliding frame moves up and down, thereby moving the second stirring rod. The movement of the second stirring rod will drive the first stirring rod to rotate, thereby changing the position of the first stirring rod. When the first stirring rod is horizontal, the length of the first stirring rod is the longest and the stirring range is the largest, which can achieve uniform mixing in a shorter time, but it will consume more energy during the stirring process. As the second stirring rod moves, it will cause the first stirring rod to tilt downward. At this time, the stirring range of the first stirring rod is smaller, but local mixing can be performed more quickly. It is suitable for high shear force stirring and has low loss. Thus, the positions of the first stirring rod and the second stirring rod can be changed to adapt to the mixing of different raw materials. At the same time, targeted mixing can be performed according to different mixing needs, resulting in better effect.

[0008] Furthermore, there are several first stirring rods arranged in a rectangle with the axis of the support frame as the center, and the number of the first stirring rods is the same as the number of the second stirring rods.

[0009] Through the above technical solution, the multiple first and second stirring rods of this application can ensure a comprehensive mixing effect.

[0010] Furthermore, the length of the strip-shaped hole is less than the length of the second stirring rod, and the shape of the strip-shaped hole is adapted to the shape of the fixing rod.

[0011] Furthermore, a third stirring rod is fixedly connected to the outer side of the bottom end of the support frame, and the third stirring rod is an arc-shaped rod.

[0012] Through the above technical solution, the third stirring rod of this application can stir the inner bottom wall of the reactor, ensuring uniform mixing and preventing accumulation.

[0013] Furthermore, the shape of the support frame is adapted to the shape of the sliding frame, and the moving ring is in contact with the inner wall of the support frame.

[0014] A reaction vessel includes a vessel body and an adjustable reaction vessel stirring mechanism. A drive motor is fixedly installed on the top of the vessel body. The output end of the drive motor passes through the vessel body and is fixedly connected to the top of a support frame. The bottom end of the support frame and the bottom end of the threaded rod are movably connected to the inner bottom wall of the vessel body. The vessel body is also provided with a feed inlet and a discharge outlet.

[0015] Through the above technical solution, this application completes the feeding and discharging process through the inlet and outlet. Starting the drive motor drives the support frame to rotate, which in turn drives the first stirring rod, the second stirring rod and the third stirring rod to rotate and mix. Then, the servo motor is started to adjust the position of the first stirring rod and the second stirring rod for targeted mixing.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] 1. The adjustable reaction vessel stirring mechanism and reaction vessel, by means of the second stirring rod following the movement of the sliding frame, can drive the first stirring rod to rotate, thereby changing the position of the first stirring rod and the second stirring rod, so as to adapt to different raw materials for stirring and mixing, and the cooperation of the first stirring rod and the second stirring rod can ensure the stirring effect, thus solving the problems mentioned in the background art.

[0018] 2. The adjustable stirring mechanism and reactor of this reactor, through the design of the third stirring rod, can stir the inner bottom wall of the reactor to prevent the accumulation or uneven stirring of the inner bottom wall of the reactor. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5This utility model provides a technical solution: an adjustable reaction vessel stirring mechanism, including a support frame 1, a first clamping plate 2 fixedly connected to the outside of the support frame 1, a first rotating rod 3 movably connected between the first clamping plates 2, a first stirring rod 4 also provided outside the support frame 1, and one end of the first stirring rod 4 movably connected to the outside of the first rotating rod 3, a sliding frame 5 movably connected to the outside of the support frame 1, a second clamping plate 6 fixedly connected to the outside of the sliding frame 5, a second rotating rod 7 movably connected between the second clamping plates 6, one end of a second stirring rod 8 fixedly connected to the outside of the second rotating rod 7, and the other end of the second stirring rod 8 movably connected to the end of the first stirring rod 4 away from the support frame 1 through a hinge 9;

[0027] A threaded rod 10 is provided inside the support frame 1. A servo motor 11 is fixedly installed on the inner top wall of the support frame 1. The output end of the servo motor 11 is fixedly connected to the top end of the threaded rod 10. A movable ring 12 is movably connected to the outer side of the threaded rod 10. A strip hole 13 is opened on the support frame 1. A fixed rod 14 is fixedly connected to the outer side of the movable ring 12. The end of the fixed rod 14 away from the movable ring 12 is slidably connected in the strip hole 13 and fixedly connected to the sliding frame 5.

[0028] In this embodiment, through the above technical solution, the servo motor 11 is started to drive the threaded rod 10 to rotate. At this time, the moving ring 12 is limited by the fixed rod 14 and will move up and down, that is, the sliding frame 5 moves up and down, thereby moving the second stirring rod 8. The movement of the second stirring rod 8 will drive the first stirring rod 4 to rotate, thereby changing the position of the first stirring rod 4. When the first stirring rod 4 is horizontal, the length of the first stirring rod 4 is the longest and the stirring range is the largest. It can be uniformly mixed in a shorter time, but more energy will be consumed in the stirring process. As the second stirring rod 8 moves, it will cause the first stirring rod 4 to tilt downward. At this time, the stirring range of the first stirring rod 4 becomes smaller, but local mixing can be carried out more quickly. It is suitable for high shear force stirring and has low loss. Thus, the positions of the first stirring rod 4 and the second stirring rod 8 can be changed to adapt to different raw materials for mixing. At the same time, targeted mixing can be carried out according to different stirring needs, and the effect is better.

[0029] The number of first stirring rods 4 is several and they are arranged in a rectangle with the axis of support frame 1 as the center. The number of first stirring rods 4 is the same as the number of second stirring rods 8.

[0030] In this embodiment, through the above technical solution, the multiple first stirring rods 4 and second stirring rods 8 of this application can ensure a comprehensive mixing effect.

[0031] The length of the strip hole 13 is less than the length of the second stirring rod 8, and the shape of the strip hole 13 is adapted to the shape of the fixing rod 14.

[0032] A third stirring rod 15 is fixedly connected to the outer side of the bottom end of the support frame 1. The third stirring rod 15 is an arc-shaped rod.

[0033] In this embodiment, through the above technical solution, the third stirring rod 15 of this application can stir the inner bottom wall of the reactor, ensuring uniform mixing while preventing accumulation.

[0034] The shape of the support frame 1 is adapted to the shape of the sliding frame 5, and the moving ring 12 is in contact with the inner wall of the support frame 1.

[0035] A reaction vessel includes a vessel body 16, a drive motor 17 is fixedly installed on the top of the vessel body 16, the output end of the drive motor 17 passes through the vessel body 16 and is fixedly connected to the top of the support frame 1, the bottom end of the support frame 1 and the bottom end of the threaded rod 10 are both movably connected to the inner bottom wall of the vessel body 16, and the vessel body 16 is also provided with a feed inlet 18 and a discharge outlet 19.

[0036] In this embodiment, through the above technical solution, the present application completes the feeding and discharging process through the inlet 18 and the outlet 19. The drive motor 17 is started to drive the support frame 1 to rotate, which can drive the first stirring rod 4, the second stirring rod 8 and the third stirring rod 15 to rotate and mix. Then, the servo motor 11 is started to adjust the position of the first stirring rod 4 and the second stirring rod 8 for targeted mixing.

[0037] In this embodiment, when the adjustable reactor stirring mechanism and the reactor are working, starting the drive motor 17 drives the support frame 1 to rotate, which in turn drives the first stirring rod 4, the second stirring rod 8 and the third stirring rod 15 to rotate and mix. Starting the servo motor 11 drives the threaded rod 10 to rotate. At this time, the moving ring 12 will move up and down due to the limitation of the fixed rod 14, that is, the sliding frame 5 moves up and down, thereby moving the second stirring rod 8. The movement of the second stirring rod 8 will drive the first stirring rod 4 to rotate, thereby changing the position of the first stirring rod 4. The two work together to adapt to different raw materials for mixing, and can also be used for targeted mixing according to different mixing needs, resulting in better effect.
