Description

Technical Field

[0001] This utility model relates to the field of mixing devices, and in particular to fluid mixers. Background Technology

[0002] The phase separation method for preparing drug-loaded microspheres is mainly based on the change in solubility of the solute in the solution. In a homogeneous solution containing the drug and the polymer (spheroidizing material), by changing the temperature, pH value, adding non-solvents, or changing the composition of the solvent, the solubility of the polymer is reduced, phase separation occurs, the drug precipitates out from the homogeneous solution and encapsulates it, forming tiny droplets, which are then solidified to obtain drug-loaded microspheres.

[0003] The main auxiliary material for preparing microspheres by phase separation method is silicone oil with high viscosity. When using traditional shearing equipment, the high viscosity of silicone oil causes a rapid pressure drop, resulting in extremely low flow rate (production), which makes it impossible to effectively mix raw materials and achieve phase separation.

The mixing tube includes a straight section and an inclined section connected to the straight section. At least a portion of the straight section is located outside the mixing chamber, and at least a portion of the inclined section is located inside the mixing chamber.

[0007] Furthermore, the multiple hybrid components are detachably connected.

[0029] Please see Figures 1 to 2 The fluid mixer includes multiple mixing components 10, which are interconnected to form the fluid mixer and are arranged in a straight line. The number of mixing components 10 is greater than or equal to three. In actual operation, the number of mixing components 10 is set according to the type of liquid to be mixed. In this embodiment, the number of mixing components 10 is three.

[0030] Please continue reading. Figure 3 Each mixing component 10 includes a mixing tube 11, a mixing chamber 12, and a sealing ring 13. The mixing tube 11 and the mixing chamber 12 are detachably connected and sealed by the sealing ring 13.

[0031] The mixing tube 11 includes a first connecting part 111 and a tube body 112, wherein the first connecting part 111 is fixed to the outer wall of the tube body 112.

[0032] The first connecting part 111 is used for a detachable connection between the mixing tube 11 and the mixing chamber 12, with the tube body 112 used for liquid flow. A first groove 1110 is provided on one side of the first connecting part 111, which is used to install a sealing ring 13 to seal the mixing tube 11 and the mixing chamber 12. The first connecting part 111 may be provided with protrusions, claws, threads, or other structures to achieve a detachable connection between the mixing tube 11 and the mixing chamber 12.

[0033] The tube body 112 includes a first connecting end 1121, a straight segment 1122, and an inclined segment 1123, with the straight segment 1122 located between the first connecting end 1121 and the inclined segment 1123. The tube body 112 is hollow, with an internal pipe to facilitate liquid flow. The first connecting end 1121 is used for detachable connection between the tube body 112 of the mixing component 10 and the mixing chamber 12 of another mixing component 10. The first connecting end 1121 is provided with a second groove 1124 for installing a sealing ring 13. The first connecting end 1121 is tapered to facilitate liquid injection. The straight segment 1122 passes through the first connecting portion 111, meaning that part of the straight segment 1122 is located on one side of the first connecting portion 111, while the remaining straight segment 1122 and the inclined segment 1123 are located on the other side of the first connecting portion 111. The inclined segment 1123 extends from the end of the straight segment 1122 and is inclined, forming an acute angle with the straight segment 1122. The tube body 112 is J-shaped as a whole.

[0034] Please continue reading. Figure 4 The mixing chamber 12 includes a second connecting part 121, a cavity 122 and a second connecting end 123, with the cavity 122 located between the second connecting part 121 and the second connecting end 123.

[0035] The second connecting portion 121 is detachably connected to the first connecting portion 111 of the mixing tube 11. The second connecting portion 121 has a third groove 1210 for installing a sealing ring 13 to ensure a tight seal between the mixing tube 11 and the mixing chamber 12. The chamber 122 is larger than the tube 112, with a portion of the straight section 1122 and an inclined section 1123 located within the chamber 122. The second connecting end 123 is detachably connected to the mixing tube 11 of another mixing component 10. The second connecting end 123 has a fourth groove 1230 for installing a sealing ring 13, ensuring a sealed connection between adjacent mixing components 10.

[0036] Please continue reading. Figure 5When assembling the fluid mixer, the first connecting portion 111 of the mixing tube 11 is detachably connected to the second connecting portion 121 of the mixing chamber 12 to form a mixing assembly 10. At this time, the first connecting end 1121 and part of the straight section 1122 of the mixing tube 11 are located outside the chamber 122, while part of the straight section 1122 and the inclined section 1123 are located inside the chamber 122. The number of mixing assemblies 10 is determined according to the viscosity of the fluid and the usage requirements, and the second connecting ends 123 of multiple mixing assemblies 10 are detachably connected to the first connecting ends 1121. After assembly, multiple mixing assemblies 10 are located on the same straight line, and the tube bodies 112 of the mixing tubes 11 of multiple mixing assemblies 10 are also located on the same straight line.

[0037] When using the fluid mixer, the fluid is injected from the first connection end 1121 of the mixing tube 11 at the end. When the fluid flows out from the inclined section 1123 to the cavity 122, the liquid tumbles because the inclined section 1123 is inclined and the outlet of the inclined section 1123 faces downward. After tumbling, the liquid enters the mixing tube 11 of the next mixing component 10. The liquid flowing out from the next inclined section 1123 continues to tumble and is further mixed.

[0038] The fluid mixer comprises multiple mixing components 10 that are sealed together. Due to the inclined arrangement of the inclined section 1123, the liquid tumbles in the mixing chamber 12, achieving rapid and uniform mixing. The multiple mixing components 10 are detachably connected, facilitating the assembly of mixers of different specifications (lengths). The mixing tube 11 and mixing chamber 12 of each mixing component 10 are detachably connected, facilitating cleaning after use. The fluid mixer is compact, has a high throughput, and is easy to clean.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
