Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for hydrogen peroxide production. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys, and other composite materials. Currently, hydrogen peroxide production requires the use of a reaction vessel, but existing reaction vessels still have certain problems in use.

[0003] For example, a hydrogen peroxide production reactor with announcement number CN211706762U has the following technical solution: During the stirring process, eddies easily occur, leading to poor stirring effect. An upper cover is installed at the upper end of the reactor body, and the upper cover is connected to the reactor body by screws. A leak-proof layer is provided between the upper cover and the reactor body. A speed reducer is installed at the upper end of the upper cover, and the speed reducer is connected to the reactor body by screws. A motor is installed at the upper end of the speed reducer, and the motor is connected to the speed reducer by screws. A stirring rod is installed at the lower end of the motor, and the stirring rod is connected to both the speed reducer and the motor by couplings. The stirring rod is connected to the reactor body by bearings. A first stirring blade is installed on the outside of the stirring rod and is welded to the stirring rod. However, existing hydrogen peroxide reactions require precise proportioning of raw materials when adding them, and the stirring space of the existing stirring structure is relatively limited, resulting in incomplete stirring and reaction.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing hydrogen peroxide production reactor. Utility Model Content

[0006] The purpose of this invention is to provide a reaction vessel for hydrogen peroxide production, so as to solve the problems mentioned in the background art, such as the inability to add raw materials one by one and insufficient stirring.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reactor for hydrogen peroxide production includes a reactor shell. Support columns are installed on both the left and right sides of the bottom of the reactor shell, and anti-vibration bases are fixedly installed at the bottom of each support column. An inlet is located on the left side of the upper surface of the reactor shell, and an exhaust port is located on the right side of the upper surface of the reactor shell. An outlet is located at the bottom of the reactor shell, and a control valve is located to the right of the outlet. A partition is horizontally arranged above the interior of the reactor shell, and a material control plate is located above the partition. A large gear is fixedly installed on the bottom surface of the partition, and a tripod is located at the bottom of the large gear. Rotating rods are located below the tripod.

[0009] Preferably, a drive motor is fixedly installed in the middle of the top surface of the reactor shell, and a rotating column is connected and installed at the output end below the drive motor. A material control plate is fixedly connected and installed in the middle of the rotating column, and two material holes are opened on the surface of the material control plate. The material holes are rotated to connect with the inlet to form a feeding structure.

[0010] Using the above technical solution, when the drive motor is started, its output shaft drives the rotating column to rotate, which in turn drives the control plate to rotate. At this time, the two material holes rotate intermittently to below the inlet, which can control the amount of material fed in and prevent the safety hazards caused by inaccurate feeding from causing a reaction.

[0011] Preferably, the bottom end of the rotating column is connected to the upper surface of the center of the tripod, and small gears are rotatably connected and installed on the upper surfaces of the three legs of the tripod.

[0012] Using the above technical solution, when the rotating column rotates, it simultaneously drives the tripod to rotate, which in turn drives the three small gears to rotate around the rotating column, providing mechanical power for the rotating rod to drive the rotating rod to stir around the rotating column.

[0013] Preferably, the pinions are all connected to the outside of the large gears by toothed threads, and the pinions are all meshed with the teeth of the large gears. Each pinion is connected to an internal gear by a rotating shaft passing through a tripod, and an external gear is connected to the outside of each internal gear by toothed threads.

[0014] With the above technical solution, since the pinion is connected to the large gear, the pinion can rotate on its own axis while rotating around the rotating column. This drives the inner gear below to rotate, and at the same time, the outer gear connected to the pinion rotates, providing mechanical power for the rotation of the rotating rod below.

[0015] Preferably, the upper end of the external gear is rotatably connected to the bottom surface of the tripod, and a rotating rod is connected and installed at the bottom end of each external gear, and a stirring rod is connected and installed on the outer side of each rotating rod.

[0016] Using the above technical solution, when the external gear rotates, it simultaneously drives the rotating rod to rotate, which in turn drives the stirring rod to rotate. At the same time, the stirring rod as a whole rotates around the rotating column, thereby increasing the stirring space range and allowing the hydrogen peroxide production process to fully react.

[0017] Preferably, the upper end of the external gear is rotatably connected to the bottom surface of the tripod, and a rotating rod is connected and installed at the bottom end of each external gear, and a stirring roller is connected and installed on the outer side of each rotating rod.

[0018] Using the above technical solution, when the external gear rotates, it simultaneously drives the rotating rod to rotate, which in turn drives the stirring roller to rotate. At the same time, the stirring roller rotates around the rotating column as the center, accelerating the fluid rotation and thus increasing the stirring space range, allowing the hydrogen peroxide production process to fully react.

[0019] Preferably, the upper end of the external gear is rotatably connected to the bottom surface of the tripod, and a rotating rod is connected and installed at the bottom end of each external gear, and a stirring paddle is connected and installed on the outer side of each rotating rod.

[0020] Using the above technical solution, when the external gear rotates, it simultaneously drives the rotating rod to rotate, which in turn drives the stirring paddle to rotate. At the same time, the stirring paddle rotates around the rotating column as the center, resulting in a large contact area with the material, thereby increasing the stirring space range and allowing the hydrogen peroxide production process to react fully.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the reaction vessel for hydrogen peroxide production,

[0022] 1. A control plate is provided. A drive motor is fixedly installed in the middle of the top surface of the reactor shell, and a rotating column is connected to the output end of the drive motor. A control plate is fixedly installed in the middle of the rotating column, and two material holes are opened on the surface of the control plate. The material holes are rotated to connect with the inlet to form a feeding structure. When the drive motor is started, its output shaft drives the rotating column to rotate, which in turn drives the control plate to rotate. At this time, the two material holes rotate intermittently to the bottom of the inlet, which can control the amount of material fed in and prevent the safety hazards of the reaction caused by inaccurate feeding.

[0023] 2. A rotating rod is provided that rotates around the rotating column. The bottom end of the rotating column is connected to the upper surface of the center of the tripod, and small gears are rotatably connected to the upper surfaces of the three legs of the tripod. When the rotating column rotates, it drives the tripod to rotate, which in turn drives the three small gears to rotate around the rotating column, providing mechanical power for the rotating rod to stir around the rotating column.

[0024] 3. Equipped with a self-rotating stirring rod, since the pinion gear is connected to the large gear, the pinion gear can rotate on its own axis while rotating around the rotating column. This drives the inner gear below to rotate, and the outer gear connected to it rotates, which in turn drives the rotating rod to rotate. This, in turn, drives the stirring rod to rotate. At the same time, the entire stirring rod rotates around the rotating column, thereby increasing the stirring space and allowing the hydrogen peroxide production process to react fully.

[0025] 4. Equipped with a self-rotating stirring roller, the upper end of the external gear is rotatably connected to the bottom surface of the tripod, and a rotating rod is connected and installed at the bottom end of the external gear. The stirring roller is connected and installed on the outer side of the rotating rod. When the external gear rotates, it drives the rotating rod to rotate, which in turn drives the stirring roller to rotate. At the same time, the stirring roller rotates around the rotating column as the center, which accelerates the fluid rotation, thereby increasing the stirring space range and allowing the hydrogen peroxide production process to react fully.

[0026] 5. Equipped with a self-rotating stirring paddle, the upper end of the external gear is rotatably connected to the bottom surface of the tripod, and a rotating rod is connected and installed at the bottom end of the external gear, and the stirring paddle is connected and installed on the outer side of the rotating rod. When the external gear rotates, it drives the rotating rod to rotate, which in turn drives the stirring paddle to rotate. At the same time, the stirring paddle rotates around the rotating column as the center, and the contact area with the material is large, thereby increasing the stirring space range and allowing the hydrogen peroxide production process to react fully.

Detailed Implementation

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-5 This utility model provides a technical solution:

[0038] A reactor for hydrogen peroxide production includes a reactor shell 1. Support columns 2 are installed on both the left and right sides of the bottom of the reactor shell 1, and anti-vibration bases 3 are fixedly installed at the bottom of each support column 2. An inlet 4 is provided on the left side of the upper surface of the reactor shell 1, and an exhaust port 7 is provided on the right side of the upper surface of the reactor shell 1. An outlet 5 is provided at the bottom of the reactor shell 1, and a control valve 6 is provided to the right of the outlet 5. A partition 8 is horizontally arranged above the interior of the reactor shell 1, and a control plate 11 is provided above the partition 8. A large gear 13 is fixedly installed on the bottom surface of the partition 8, and a tripod 14 is provided at the bottom of the large gear 13. Rotating rods 18 are provided below each tripod 14.

[0039] A drive motor 9 is fixedly installed in the middle of the top surface of the reactor shell 1. A rotating column 10 is connected to the output end of the drive motor 9. A control plate 11 is fixedly connected to the middle of the rotating column 10. Two material holes 12 are opened on the surface of the control plate 11, and the material holes 12 are rotated to connect with the inlet 4 to form a feeding structure. When the drive motor 9 is started, its output shaft drives the rotating column 10 to rotate, which in turn drives the control plate 11 to rotate. At this time, the two material holes 12 rotate intermittently to the bottom of the inlet 4, which can control the amount of material fed in and prevent the safety hazards of inaccurate feeding from causing a reaction.

[0040] The bottom end of the rotating column 10 is connected to the upper surface of the center of the tripod 14, and small gears 15 are rotatably connected and installed on the upper surfaces of the three legs of the tripod 14. When the rotating column 10 rotates, it drives the tripod 14 to rotate, which in turn drives the three small gears 15 to rotate around the rotating column 10, providing mechanical power for the rotating rod 18 to stir around the rotating column 10.

[0041] All pinions 15 are threadedly connected to the outside of the large gear 13, and all pinions 15 mesh with the threads of the large gear 13. Below each pinion 15, an internal gear 16 is connected and mounted via a rotating shaft through a tripod 14. External gears 17 are threadedly connected and mounted to the outside of each internal gear 16. The upper end of each external gear 17 is rotatably connected to the bottom surface of the tripod 14, and a rotating rod 18 is connected and mounted to the bottom of each external gear 17. A stirring rod 19 is connected and mounted to the outside of each rotating rod 18. Because the pinions 15 are threadedly connected to the large gear 13, when the pinions 15 rotate around the rotating column 10, they also rotate on their own axis. This drives the internal gears 16 below to rotate, and simultaneously, the external gears 17 rotate, providing mechanical power for the rotation of the rotating rod 18 below. When the external gear 17 rotates, it simultaneously drives the rotating rod 18 to rotate, which in turn drives the stirring rod 19 to rotate. The stirring rod 19 rotates around the rotating column 10, thereby increasing the stirring space and allowing for a more complete reaction in the hydrogen peroxide production process.

[0042] Example 2

[0043] See also Figure 6 This utility model provides a technical solution:

[0044] The upper end of the external gear 17 is rotatably connected to the bottom surface of the tripod 14, and a rotating rod 18 is connected and installed at the bottom end of the external gear 17. A stirring roller 20 is connected and installed on the outer side of the rotating rod 18. When the external gear 17 rotates, it drives the rotating rod 18 to rotate, which in turn drives the stirring roller 20 to rotate. At the same time, the stirring roller 20 rotates around the rotating column 10 as the center, accelerating the fluid rotation and thus increasing the stirring space range, allowing the hydrogen peroxide production process to react fully.

[0045] Example 3

[0046] See also Figure 7 This utility model provides a technical solution:

[0047] The upper end of the external gear 17 is rotatably connected to the bottom surface of the tripod 14, and a rotating rod 18 is connected and installed at the bottom end of the external gear 17. A stirring paddle 21 is connected and installed on the outer side of the rotating rod 18. When the external gear 17 rotates, it drives the rotating rod 18 to rotate, which in turn drives the stirring paddle 21 to rotate. At the same time, the stirring paddle 21 rotates around the rotating column 10 as the center, and the contact area with the material is large, thereby increasing the stirring space range and allowing the hydrogen peroxide production process to react fully.

[0048] Working principle:

[0049] When this utility model is in use, when the drive motor 9 is started, its output shaft drives the rotating column 10 to rotate, which in turn drives the control plate 11 to rotate. At this time, the two material holes 12 rotate intermittently to below the inlet 4, which can control the amount of material fed in and prevent the safety hazards caused by inaccurate feeding. When the rotating column 10 rotates, it also drives the tripod 14 to rotate, which in turn drives the three small gears 15 to rotate around the rotating column 10. Since the teeth of the small gears 15 are connected to the large gear 13, the small gears 15 can also rotate on their own axis when rotating around the rotating column 10. In turn, the small gears 15 drive the inner gear 16 below to rotate, and the outer gear 17 connected to the teeth rotates, which in turn drives the rotating rod 18 to rotate, which in turn drives the stirring rod 19 to rotate, thereby increasing the stirring space range and allowing the hydrogen peroxide to react fully.
