Description

Technical Field

[0001] This utility model belongs to the technical field of reaction equipment, and in particular relates to a multi-directional reactor stirring device. Background Technology

[0002] A reactor is a core piece of equipment used to realize chemical or physical reaction processes, and it is widely used in chemical engineering, oil refining, metallurgy, pharmaceuticals, and the preparation of new energy materials. Depending on the process requirements, reactors can be used for single-phase liquid reactions, as well as multiphase reaction systems such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid.

[0003] Existing reactors mostly use a single anchor, paddle, or turbine-type central agitator. Although they can achieve basic mixing functions, the mixing range is mainly concentrated in the central area of ​​the tank. They have a weak ability to disturb materials near the tank wall, which makes it easy for flow dead zones to form in the side areas. In these areas, the material has poor flowability and insufficient mixing, which in turn leads to uneven mixing, reduced mass transfer efficiency, and may also generate local concentration gradients, affecting the uniformity of product quality.

[0004] Therefore, a multi-directional reactor stirring device is particularly needed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing reactors, such as limited stirring range, easy formation of dead zones near the tank wall, resulting in uneven mixing, low mass transfer efficiency and local uneven concentration, this utility model provides a multi-directional reactor stirring device.

[0006] This utility model is achieved through the following technical means: A multi-directional reactor stirring device includes a support frame, a tank, an inlet, an outlet, a solenoid valve, a motor, a main stirring frame, and a controller. The tank is installed within the annular space of the support frame. Multiple inlets are fixedly connected to the upper part of the tank, and an outlet is fixedly connected to the lower part of the tank. A solenoid valve is installed on the outlet. A motor is installed at the center of the top of the tank. The main stirring frame is rotatably installed inside the tank. The output shaft of the motor extends into the tank and is fixedly connected to the main stirring frame. A controller, solenoid valve, and motor are installed at a high position at the front of the tank. All components are electrically connected to the controller and include a rotating plate, side stirring racks, a large gear, an internal gear ring, a fixed plate, and a small gear. A rotating plate is rotatably mounted on the lower part of the tank, with the bottom surface of the rotating plate flush with the bottom surface of the tank. Multiple side stirring racks are fixedly mounted on the rotating plate, evenly distributed around its center. The main stirring rack passes through the rotating plate and extends to the other end of the tank, where a large gear is fixedly mounted. An internal gear ring is fixedly mounted on the bottom of the rotating plate, and a fixed plate is fixedly mounted on the bottom of the tank. A small gear is rotatably mounted on the fixed plate, meshing with both the large gear and the internal gear ring.

[0007] Furthermore, it also includes a scraper, which is fixed to the rotating plate and adheres tightly to the inner wall of the tank.

[0008] Furthermore, the side agitator is positioned close to the inner wall of the tank.

[0009] Furthermore, the discharge port is arranged at an angle.

[0010] Furthermore, the motor's output shaft passes through the upper part of the scraper.

[0011] Furthermore, a sealed bearing seat is provided at the penetration point between the rotating plate and the main mixing frame.

[0012] Beneficial effects: This utility model achieves efficient mixing in the central area through a motor and a main mixing frame. At the same time, with the help of the main mixing frame, the power is transmitted to the rotating plate through the large gear, small gear, and internal gear ring, driving the side mixing frame to revolve. The main and auxiliary mixing work together to form a multi-directional mixing flow field, effectively eliminating mixing dead zones and improving the uniformity of materials.

[0021] Example: A multi-directional reactor stirring device, such as Figures 1-7 As shown, the system includes a support frame 1, a tank 2, an inlet 3, an outlet 4, a solenoid valve 5, a motor 6, a main mixing frame 7, and a controller 15. The tank 2 is bolted to the annular space of the support frame 1. Three inlets 3 are fixedly connected to the upper part of the tank 2, and an outlet 4 is fixedly connected to the lower part of the tank 2. The outlet 4 is inclined to facilitate smooth material discharge. Flanges are provided on both the inlets 3 and outlet 4. A solenoid valve 5 is installed on the outlet 4. A motor 6 is bolted to the center of the top of the tank 2. The main mixing frame 7 is rotatably mounted inside the tank 2. The output shaft of the motor 6 extends into the tank 2 and is fixedly connected to the main mixing frame 7 via a coupling. The controller 15 is bolted to the high front of the tank 2. The solenoid valve 5 and the motor 6 are electrically connected to the controller 15. The controller 15 is a programmable logic controller (PLC), model Huichuan Easy. The 521-24T4DT also includes a rotating plate 8, side stirring racks 9, scrapers 10, a large gear 11, an internal gear ring 12, a fixed plate 13, and a small gear 14. A rotating plate 8 is rotatably mounted on the lower part of the tank body 2, with its bottom surface flush with the bottom surface of the tank body 2. Four side stirring racks 9 are fixedly connected to the rotating plate 8, evenly distributed around its center. The four side stirring racks 9 are arranged around the main stirring rack 7, close to the inner wall of the tank body 2. Scrapers 10 are fixedly connected to the rotating plate 8, adhering tightly to the inner wall of the tank body 2. A motor 6... The output shaft passes through the upper part of the scraper 10, providing rotation guidance and structural support for the upper part of the scraper 10. The main stirring frame 7 passes through the rotating plate 8 and extends to the lower end of the tank body 2, where a large gear 11 is fixedly connected. A sealed bearing seat is provided at the penetration part between the rotating plate 8 and the main stirring frame 7 to achieve dynamic sealing during the rotation of the main stirring frame 7. An internal gear ring 12 is fixedly connected to the bottom of the rotating plate 8, and a fixed plate 13 is fixedly connected to the bottom of the tank body 2. A small gear 14 is rotatably mounted on the fixed plate 13, and the small gear 14 meshes with both the large gear 11 and the internal gear ring 12.

[0022] When this device is needed, the operator first injects the various materials to be mixed into the tank 2 through the feed inlet 3. Then, the operator starts the motor 6 through the controller 15. The output shaft of the motor 6 drives the main stirring frame 7 to rotate. The main stirring frame 7 drives the large gear 11 to rotate. The large gear 11 meshes with the small gear 14, driving the small gear 14 to rotate. The small gear 14 meshes with the internal gear ring 12, transmitting the rotational power to the internal gear ring 12, which drives the rotating plate 8 to rotate around the central axis of the tank 2. The multiple side stirring frames 9 on the rotating plate 8 also revolve around the central axis, and during the rotation, they stir the materials in the side areas of the tank 2. During the mixing process, the main mixing rack 7 continuously rotates and mixes in the central area, enabling the main mixing rack 7 and multiple side mixing racks 9 to work collaboratively in different spatial areas, thereby improving the overall mixing efficiency and uniformity. During the mixing process, the rotating plate 8 drives the scraper 10 to rotate around the output shaft of the motor 6, scraping off the material adhering to the inner wall of the tank 2. After the mixing is completed, the solenoid valve 5 is opened to open the discharge port 4, and the uniformly mixed material is smoothly discharged through the discharge port 4. After the material is discharged, the solenoid valve 5 is closed to block the passage of the discharge port 4, and then the motor 6 is turned off to complete the mixing operation process.
