Abstract
Description
Technical Field
[0001] This invention belongs to the field of biodegradable material production technology, and more specifically, relates to a high-efficiency gas-liquid mixing agitator. Background Technology
[0002] Carbon dioxide-based polyester is an environmentally friendly biodegradable material that uses carbon dioxide as one of its raw materials. It fully utilizes carbon dioxide resources and possesses excellent barrier properties, transparency, and heat-sealing strength, making it widely used in various fields such as medical, packaging, tableware, aerospace, sheet metal, and shipbuilding manufacturing. The processing of carbon dioxide-based polyester requires a gas-liquid mixer to thoroughly mix the carbon dioxide gas, epoxy compound liquid, and catalyst. Existing gas-liquid mixers mainly consist of a mixing tank, a drive motor, and stirring blades. Carbon dioxide gas is injected from the bottom of the mixing tank, and the drive motor drives the stirring blades to break up the air bubbles, resulting in a uniform mixture with the liquid inside the tank.
[0003] The existing application number CN202022419162.2 discloses a gas-liquid mixing reactor, including a reaction chamber. An inlet pipe is connected to the left side of the reaction chamber, and a gas storage pipe is fixed to the left inner wall of the reaction chamber. The right end of the inlet pipe passes through the reaction chamber and connects to the gas storage pipe. Several evenly distributed outlet pipes are connected to the right side of the gas storage pipe. This invention effectively controls the flow rate of the reaction liquid through the setting of a first overflow tank and a second overflow tank, allowing the reactants to react fully. The spray head increases the reaction contact area of the reaction gases, greatly improving the reaction rate. The U-shaped first motor shaft and connecting rod cooperate to move the stirring blades up and down, and the rotating rod and second motor cooperate to rotate the stirring blades. Ultimately, the stirring blades can move up and down while rotating and stirring, making the stirring more thorough and greatly improving the reaction rate of the reactants.
[0004] Based on the above, most existing gas-liquid mixing agitators use sealed bearings to seal the drive motor and the mixing tank. However, with prolonged use or changes in operating conditions, the seals inside the sealed bearings are prone to wear, corrosion, and leakage. If this is not detected in time, it can affect the gas pressure balance inside the mixing tank. Utility Model Content

[0052] The mixing component is located inside the mixing tank 1.
[0053] The hybrid components include:

[0055] Turbine blade 302 is fixedly installed in the middle of drive shaft 3;
[0056] Anchor blades 303 are fixedly mounted on the top of the drive shaft 3. Their function is to drive the drive shaft 3 when gas is injected into the mixing tank 1 from the bottom. The drive motor 2 rotates the drive shaft 3, which in turn rotates the propeller blades 301, turbine blades 302, and anchor blades 303. The gas first passes through the propeller blades 301, whose large blades and special tilt angle design generate a strong axial flow, rapidly lifting the gas from the bottom of the mixing tank 1 and promoting initial gas-liquid mixing. The middle layer consists of turbine blades 302, which, during high-speed rotation, create a strong radial flow, performing secondary shearing and mixing of the gas and liquid, breaking up large bubbles, and increasing the gas-liquid contact area. The top anchor blades 303 scrape off material adhering to the inner wall of the mixing tank 1, preventing material accumulation and ensuring uniform mixing throughout the mixing tank 1.
[0057] The hybrid components also include:
[0058] The baffle 101 is provided in multiple sets, arranged in a circumferential array at the bottom of the mixing tank 1. Its function is to block and turbulent the liquid inside the mixing tank 1, change the flow direction of the liquid, suppress the circumferential motion of the liquid, promote the formation of an up-and-down circulating flow, enhance the gas-liquid mixing effect, and improve the mixing efficiency.
[0059] The specific usage and function of this embodiment are as follows:
[0060] When gas is injected into the mixing tank 1 from the bottom, the drive motor 2 drives the drive shaft 3 to rotate. The rotation of the drive shaft 3 drives the propeller blades 301, turbine blades 302, and anchor blades 303 to rotate. The gas first passes through the propeller blades 301, whose large blades and special tilt angle design generate a strong axial flow, rapidly lifting the gas from the bottom of the mixing tank 1 and promoting initial gas-liquid mixing. The middle layer is the turbine blades 302, which form a strong radial flow when rotating at high speed, performing secondary shearing and mixing of gas and liquid, breaking up large bubbles, and increasing the gas-liquid contact area. The top is the anchor blades 303, which can scrape off the material adhering to the inner wall of the mixing tank 1, preventing material accumulation and ensuring uniform mixing of materials throughout the mixing tank 1.
[0061] The baffle 101 obstructs and turbulents the liquid inside the mixing tank 1, changes the direction of liquid flow, suppresses the circular motion of the liquid, promotes the formation of an up-and-down circulating flow, enhances the gas-liquid mixing effect, and improves the mixing efficiency.
[0062] Example 2:
[0063] Based on Example 1, such as Figures 1 to 5 As shown, it also includes:
[0064] Warning component, the warning component is located on the outside of drive shaft 3.

[0066] The transmission piston ring 503 is slidably connected inside the sealing monitor 5;
[0067] The elastic element 505 is fixedly installed at the top of the sealing monitor 5 and the middle position of the transmission piston ring 503; its function is that the elastic element 505 drives the transmission piston ring 503 to slide inside the sealing monitor 5 under the action of elasticity.
[0068] The warning component also includes:
[0069] Through holes 502, multiple sets of through holes 502 are provided, and multiple sets of through holes 502 are opened at the bottom of the sealing monitor 5;
[0070] The sealing ring 501 is fixedly installed between the sealing monitor 5 and the sealing bearing 4. Its function is to connect the sealing bearing 4 and the sealing monitor 5 through the through hole 502, and to enhance the sealing effect between the sealing bearing 4 and the sealing monitor 5, so as to prevent gas from leaking from the connection between the two.
[0071] The warning component also includes:
[0072] Alarm device 6 is fixedly installed on one side of the seal monitor 5;
[0073] Metal conductive post 504 is fixedly installed at the bottom of transmission piston ring 503;
[0074] The conductive electrode 601 is fixedly installed inside the warning device 6 and the sealing monitor 5. Its function is to drive the metal conductive column 504 to move, and the metal conductive column 504 moves to contact the conductive electrode 601.
[0075] The warning component also includes:
[0076] Buzzer 603 is fixedly installed inside the alarm 6;
[0077] The power supply mechanism 602 is fixedly installed inside the alarm 6.

Its function is that when the metal conductive post 504 moves to contact the conductive electrode 601, the switching circuit is connected and energized, causing the buzzer 603 to sound an alarm.
[0078] The specific usage and function of this embodiment are as follows:
[0079] When the seal inside the sealed bearing 4 leaks, gas enters the seal monitor 5 through the through hole 502, increasing the internal pressure of the seal monitor 5 and pushing the transmission piston ring 503 to slide inside the seal monitor 5 and compress the elastic element 505. The movement of the transmission piston ring 503 drives the metal conductive column 504 to move. The metal conductive column 504 moves and contacts the conductive electrode 601, connecting the switch circuit and energizing it. This causes the buzzer 603 to sound as a warning, prompting staff to perform timely inspection and maintenance.
