Description

Technical Field

[0001] This utility model relates to the field of chemical mixing equipment technology, specifically a three-axis linkage synthesis mixing equipment. Background Technology

[0002] Traditional mixing equipment in existing technologies commonly employs reaction vessels, stirred tanks, and mixers. In chemical mixing operations, the solvent containing the chemicals needs to react fully with oxygen in the air. Traditional stirred tanks can only apply a stirring force to the solvent, keeping it in a continuously rotating inertial frame, which cannot increase the contact area with oxygen in the air. Some existing technologies have made improvements to address this problem by adding aeration devices to the stirred tank to increase the amount of air mixed in with the stirred solvent. However, this technical solution still does not significantly and efficiently increase the reaction efficiency between air / oxygen and the solvent.

[0003] Therefore, there is an urgent need to design a three-axis linkage synthesis and mixing device to increase the contact area between the solvent containing chemicals and the air, and to accelerate the reaction rate and efficiency of oxygen in the air with chemicals. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a three-axis linkage synthesis and mixing device to increase the contact area between the solvent containing chemicals and the air, thereby accelerating the reaction rate and efficiency of oxygen in the air with the chemicals.

[0007] Preferably, the present invention further includes: the three rotating shafts are evenly arranged along the circumferential direction of the central axis of the outer cylinder and located inside the outer cylinder, the inner cylinders on the three rotating shafts surround each other to form an inner duct, and the gap between the inner cylinders on the three rotating shafts and the outer cylinders forms an outer duct.

Detailed Implementation

[0020] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] This invention provides a three-axis linkage synthesis and mixing device.

[0022] Example 1:

[0023] See Figures 1 to 4 This embodiment provides a three-axis linkage synthesis and mixing device. The device is set on the ground by a frame structure and includes: a motor, a gearbox, an outer cylinder 1, and a shell.

[0024] The outer cylinder 1 is housed within a sealed outer shell. The motor and gearbox are located on top of the outer cylinder 1. A vortex shell 2 is also located on top of the outer cylinder 1, with the vortex shell 2 avoiding contact with the motor and gearbox. The bottom of the vortex shell 2 has three openings that communicate with the interior of the outer cylinder 1. Several layers of annular separation discs 9 are also provided on the inner wall of the outer cylinder 1, and air inlets are also provided on the periphery of the outer cylinder 1.

[0025] Three rotating shafts 4 are evenly arranged circumferentially along the central axis of the outer cylinder 1. The top ends of the three rotating shafts 4 are connected to a motor via a gearbox, and the motor can drive the three rotating shafts 4 to rotate synchronously. Each rotating shaft 4 is also provided with an inner cylinder 5, which is a cylinder with a through hole in the vertical direction at the center of the inner cylinder 5 to accommodate the rotating shaft 4.

[0026] The upper part of the inner cylinder 5 is provided with several gas-liquid separation plates 6 along its outer circumference. The rotation of the rotating shaft 4 drives the inner cylinder 5, thereby driving the gas-liquid separation plates 6 to rotate. The gap formed by the inner cylinder 5 enclosing the three rotating shafts 4 is the inner channel 10, which is located at the central axis of the outer cylinder 1. The gap between the inner cylinder 5 and the outer cylinder 1 forms the outer channel 11. The airflow can flow between the inner channel 10 and the outer channel 11 and fully contact and mix with the liquid inside the outer cylinder 1.

[0027] The inner diameter of the opening at the bottom of the vortex shell 2 matches the outer diameter of the inner cylinder 5 with the gas-liquid separation plate 6, with a slight gap.

[0028] The lower part of the inner cylinder 5 is provided with several layers of parallel blades 7 along the outer periphery. Each blade 7 has an inclination angle and is evenly arranged along the circumference of the inner cylinder 5. The blades 7 are located inside the outer cylinder 1 and in the lower section of the connecting cavity, and a continuous shearing trajectory is formed between adjacent blades 7.

[0029] Specifically: the top of an inclined blade is the shearing start point 7.2 and the bottom is the shearing end point 7.1. Among the upper and lower adjacent blades 7, the shearing end point 7.1 of the upper blade 7 and the shearing start point 7.2 of the adjacent lower blade 7 are in a matching relationship. By setting a phase difference between the upper and lower adjacent blades 7, a matching relationship with an inclined angle can be formed between the upper and lower adjacent blades 7. The shearing zone of each layer of blades 7 is spirally covered along the axis of the inner cylinder 5, forming a continuous inclined shearing channel.

[0030] Driven by a motor, the inner cylinder 5 rotates at high speed, causing the blades 7 and the gas-liquid separation plate 6 to rotate accordingly. Under the influence of the rotation of the blades 7 and the inclined shearing channel, the blades 7 generate a centrifugal force on the liquid and gas inside the outer cylinder 1, driving and guiding the liquid and gas upwards along the inclined shearing channel. The liquid collides and shears with the blades 7 in the inclined shearing channel and between the upper and lower layers, shearing the liquid into atomized particles. The atomized liquid then fully contacts and mixes with the rising gas.

[0031] When the unatomized liquid, atomized particles, and air are lifted by the blade 7 to the upper part of the outer cylinder 1, they detach from the blade 7 and collide with the gas-liquid separation plate 6. The gas-liquid separation plate 7 is vertically arranged, and as the inner cylinder 5 rotates, the gas-liquid separation plate 7 applies a horizontal force to the unatomized liquid and atomized particles, causing the unatomized liquid and atomized particles to move laterally away from the inner cylinder 5 and impact the separation disc 9 of the outer cylinder 1.

[0032] Unatomized liquid with higher density and mass is thrown onto the separation disk 9 in a horizontal direction under the transverse sweeping and rotation action of the gas-liquid separation plate 6, and flows downward under the action of gravity, preventing the unatomized liquid from entering the vortex shell 2.

[0033] After the dense and massive atomized particles collide with the annular separation disk 9, they form droplets. Under the action of gravity, the droplets flow down the multi-layered separation disk to the bottom of the outer cylinder 1, preventing the atomized particles from entering the vortex shell 2. In addition, they will mix with the rising gas during the laminar flow process.

[0034] Air with lower density and mass will flow into the vortex shell 2 through the gap between the opening at the top of the outer cylinder 1 and the bottom of the vortex shell 2, driven by the rising air.

[0035] The vortex shell 2 includes an inner circular flow channel 2.1 and an outer circular flow channel 2.2. The bottom of the inner circular flow channel 2.1 is connected to the outer cylinder 1. The outer circular flow channel 2.2 is arranged around the periphery of the inner circular flow channel 2.1, with one end connected to the inner circular flow channel 2.1 and the other end connected to the outlet 3. The gas entering the vortex shell 2 first enters the inner circular flow channel 2.1, then flows into the outer circular flow channel 2.2 and finally flows out from the outlet 3. Furthermore, the outer circular flow channel 2.2 has a structure that gradually widens from the inner circular flow channel 2.1 to the outlet 3. Under the action of this structure of the vortex shell 2, some of the moisture in the air entering the vortex shell 2 will condense into droplets on the inner wall of the vortex shell 2. The bottom of the vortex shell 2 is provided with several microporous return gap channels, which are connected to the outer cylinder 1. Under the action of gravity, the droplets flow into the return gap channels along the inner wall of the vortex shell 2 and then flow into the outer cylinder 1 from the return gap channels, so that the liquid flows back into the equipment.

[0036] Three rotary bearing seats are provided on the outer side of the bottom of the outer cylinder 1. The bottom of the three rotary shafts 4 passes through the outer cylinder 1 and is set in the rotary bearing seats. The rotary bearing seats provide support for the rotary shafts 4 and ensure the free rotation of the rotary shafts 4.

[0037] An air inlet is also provided on the side wall of the outer shell. The air inlet of the outer shell is connected to the air inlet provided on the side wall of the outer cylinder 1. External air is injected into the outer cylinder 1 through the air inlet by an external fan or booster pump.

[0038] The outer cylinder 1 has a liquid inlet on its side and a liquid outlet 12 at its bottom. The liquid inlet is positioned to avoid interference with the volute 2, the motor, and the gearbox. Under the influence of gravity, the liquid deposited at the bottom of the outer cylinder 1 flows out from the liquid outlet 12 and is then injected back into the outer cylinder 1 through the liquid circulation pipeline and the booster pump.

[0039] The outer cylinder 1 is also equipped with a vacuum machine, a pressure gauge, a negative pressure gauge, and a thermometer. Preferably, the air inlet of the outer shell can be closed, and a vacuum negative pressure state inside the outer cylinder 1 can be achieved by continuously evacuating air from the air outlet 3 using a fan.

[0040] Example 2:

[0041] This embodiment provides a mixing reaction method using the aforementioned three-axis linkage synthesis mixing equipment. The method is as follows: S1. The mixture or compound to be processed is added into the equipment through the liquid inlet at the top of the equipment; S2. The motor is started, driving the three rotating shafts 4 and the inner cylinder 5 to rotate synchronously; S3. The inclined blades 7 on the inner cylinder 5 generate an upward airflow in the inner channel 10 enclosed by the three rotating shafts 4 and the inner cylinder 5; S4. The upward airflow pushes the mixture or compound upward from the bottom of the outer cylinder 1, while the blades 7 on the inner cylinder 5 cut, shear, mix, and disperse the mixture or compound; S5. The mixture or compound undergoes gas-liquid separation at the gas-liquid separation plate 6 at the top of the outer cylinder 1. The separated gas forms droplets in the vortex shell 2 and condenses into droplets on the wall, flowing back into the equipment. The gas is discharged at the gas outlet 3 of the vortex shell 2. a. Gas rises into the inner channel 10 of the rotating shaft 4 and enters the top of the outer cylinder 1. The gas-liquid separation plate 6 of the inner cylinder 5 on the three rotating shafts 4 rotates to filter the liquid in the gas. After the gas enters the vortex shell 2, the moisture is further separated on the inner wall of the vortex shell 2 and then discharged from the outlet 3; b. The liquid mixture or compound is diffused in the inner cylinder 5 of the three rotating shafts 4 and is sprayed on the separation disk 9 on the inner wall of the outer cylinder 1. It is repeatedly mixed in layers along the separation disk 9 by gravity and then flows into the liquid outlet 12; S6. Gas outside the outer cylinder 1 enters from the inlet and, through the rotating blade 7 on the inner cylinder 5, drives the liquid mixture or compound flowing down under gravity to re-enter the inner channel 10 for mixing; S7. The above steps are repeated to achieve continuous cyclic mixing reaction.

[0042] Example 3:

[0043] This embodiment provides a method for preparing ferric oxalate, with the following specific steps: A1. Add ferrous oxalate solution to a triaxial linkage synthesis mixing device; A2. Introduce air into the device at a flow rate of 100m³ - 150m³ / h using the device's fan to promote the oxidation reaction; A3. Utilize the triaxial linkage rotation to mix the air and liquid at high speed, generating nano-molecules with bubble dynamics within the device to achieve the oxidation of ferrous oxalate; A4. Without adding hydrogen peroxide or any external oxidant, adjust the device speed to 800 r / min and maintain the temperature at 30℃; A5. Under the above conditions, continue stirring for 2 hours to complete the oxidation conversion of ferrous oxalate and generate ferric oxalate.

[0044] In the processing test of lithium battery electrolytes containing ferrous oxalate, the equipment was able to save 20% of raw materials, improve compound processing efficiency by 35%, and reduce energy consumption by 25%. Processing time was shortened by 50%, energy consumption was reduced by 30%, and production efficiency was increased by 40%. By changing the process conditions for compound processing, optimizing and shortening the time, the processing steps were significantly reduced, improving processing efficiency and reducing costs.
