Description

Technical Field

[0001] This invention belongs to the technical field of stirring equipment, and particularly relates to a stirring structure for lipid molecule synthesis processes. Background Technology

[0002] Lipid molecule synthesis often involves heterogeneous reactions, especially in laboratory research and industrial scale-up. The existence of heterogeneous reactions poses specific requirements and challenges to reaction efficiency, process conditions, and equipment selection. For the vast majority of heterogeneous reactions, the reaction outcome is significantly influenced by the stirring effect; the quality of the stirring directly determines the mass transfer efficiency, which is often the rate-determining step in such reactions. Existing mechanical or magnetic stirring structures are insufficient to meet the stirring requirements in some lipid molecule synthesis reactions and require further improvement.

[0003] For example, a Chinese utility model patent discloses a stirring impeller [application number: 201320344433.X], which is used for the production of polyaluminum chloride coagulant. The stirring impeller includes a stirring shaft, an upper impeller and a lower impeller disposed on the stirring shaft. The upper impeller and the lower impeller are arranged in a cross pattern. Both the upper impeller and the lower impeller include a first straight blade and a second straight blade that are centrally symmetrical. The longitudinal axes of the first straight blade and the second straight blade are both perpendicular to the stirring shaft. The first straight blade and the second straight blade are both inclined. The outer surface of the stirring impeller is integrally provided with a random copolymer polypropylene anti-corrosion layer. The stirring shaft, the upper impeller and the lower impeller are all wrapped in the random copolymer polypropylene anti-corrosion layer.

[0004] This utility model patent uses double-layer blades to make the mixing more thorough, but this improvement still has limited effect on the mixing effect and needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a stirring structure for lipid molecule synthesis.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stirring structure for lipid molecule synthesis includes a stirring rod and a plurality of blade units connected to the stirring rod. Each blade unit includes a mounting assembly and blades connected to the outer side of the mounting assembly. The mounting assembly is a hollow cylinder and is sleeved on the stirring rod. The mounting assembly is detachably connected to the stirring rod.

[0007] In the above-mentioned stirring structure for lipid molecule synthesis, the outer surface of the stirring rod has a guide groove recessed into the stirring rod, and the inner surface of the mounting assembly has a guide block protruding therefrom, the guide block being slidably connected in the guide groove.

[0008] In the above-mentioned stirring structure for lipid molecule synthesis, the mounting assembly includes a mounting cylinder and a fastening cylinder. The mounting cylinder has a clamping member made of elastic material protruding from one end near the fastening cylinder. The fastening cylinder has a squeezing ring inside. When the fastening cylinder is connected to the mounting cylinder, the squeezing ring presses against the outer wall of the clamping member and applies an inward contraction force to the clamping member.

[0009] In the above-mentioned stirring structure for lipid molecule synthesis, the clamping member is connected end to end in a ring; the inner diameter of the clamping ring gradually decreases from one end near the mounting cylinder to the other end.

[0010] In the above-mentioned stirring structure for lipid molecule synthesis, the fastening cylinder has a threaded part with an external thread on its outer surface at one end near the mounting cylinder, and the end of the mounting cylinder is recessed inward to form a threaded groove with an internal thread. When the threaded part is fitted into the threaded groove, the outer surface of the mounting cylinder is flush with the outer surface of the fastening cylinder.

[0011] In the above-mentioned stirring structure for lipid molecule synthesis, there are two fastening cylinders, which are symmetrically connected on both sides of the mounting cylinder.

[0012] In the above-mentioned stirring structure for lipid molecule synthesis, a connecting sleeve is fixedly provided on the side of the mounting component. The connecting sleeve extends radially along the mounting component. One end of the blade is fitted inside the connecting sleeve and connected to the connecting sleeve through a mounting hole. The mounting hole is provided on the connecting sleeve and the blade. There are several mounting holes, which are arranged at equal intervals along the length direction of the blade.

[0013] In the above-mentioned stirring structure for lipid molecule synthesis, several connecting sleeves are provided and are evenly distributed along the circumference of the mounting assembly.

[0014] In the above-mentioned stirring structure for lipid molecule synthesis, the blade has a first through hole and a second through hole on its two sides, respectively. The first through hole and the second through hole are interconnected, with the first through hole being horizontal and the second through hole being inclined downward.

[0015] In the above-mentioned stirring structure for lipid molecule synthesis, the thickness of the blade near the mounting assembly is greater than the thickness of the blade away from the mounting assembly.

[0016] Compared with existing technologies, the advantages of this utility model are: 1. The bladed mounting assembly of this utility model is detachably connected to the stirring rod. Multiple mounting assemblies can be added to the stirring rod as needed, thereby greatly improving the stirring effect.

[0017] 2. This utility model utilizes a funnel-shaped clamping ring to press the elastic clamping component, thereby making the clamping component tightly adhere to the stirring rod, thus achieving the fixation between the installation component and the stirring rod. The assembly and disassembly method is simple and convenient to use.

[0018] 3. The blade of this utility model is also provided with a first through hole and a second through hole, wherein the second through hole is set in an inclined downward manner, so that during the stirring process, part of the solution can flow along the axis of the stirring rod through the first through hole and the second through hole, thereby enhancing the mixing uniformity of the solution along the axis of the stirring rod and further improving the stirring effect.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Combination Figure 1 and Figure 2 As shown, a stirring structure for lipid molecule synthesis includes a stirring rod 1 and several blade units 2 connected to the stirring rod 1. Each blade unit 2 includes a mounting assembly 3 and blades 4 connected to the outer side of the mounting assembly 3. The mounting assembly 3 is a hollow cylinder and is sleeved on the stirring rod 1. The mounting assembly 3 is detachably connected to the stirring rod 1.

[0022] In use, the blades 4 are connected to the stirring rod 1 by the mounting component 3. Since the mounting component 3 and the stirring rod 1 are detachably connected, multiple sets of mounting components 3 can be added to the stirring rod 1 as needed to increase the number of blades 4 that actually perform the stirring function during stirring, thereby greatly improving the stirring effect.

[0023] Preferably, the outer surface of the stirring rod 1 has a guide groove 5 recessed into the stirring rod 1, and the inner surface of the mounting component 3 has a guide block 6 protruding from it. The guide block 6 is slidably connected within the guide groove 5. The guide groove 5 and the guide block 6 cooperate with each other to facilitate the installation process of the mounting component 3 and guide it during installation.

[0024] Combination Figure 2 and Figure 3 As shown, the mounting assembly 3 includes a mounting cylinder 31 and a fastening cylinder 32. A clamping member 33 made of elastic material protrudes from one end of the mounting cylinder 31 near the fastening cylinder 32. A clamping ring 34 is provided inside the fastening cylinder 32. When the fastening cylinder 32 is connected to the mounting cylinder 31, the clamping ring 34 presses against the outer wall of the clamping member 33 and applies an inward contraction force to the clamping member 33. Figure 5 As shown, the inner diameter of the clamping ring 34 gradually decreases from one end near the mounting cylinder 31 to the other, thus forming a trumpet shape. This trumpet-shaped structure gradually applies pressure to the clamping member 33 during the screwing process of the internal thread 38 and the external thread 35. Therefore, this utility model utilizes the trumpet-shaped clamping ring 34 to clamp the elastic clamping member 33, thereby making the clamping member 33 tightly adhere to the stirring rod 1, thus achieving the fixation between the mounting assembly 3 and the stirring rod 1. The assembly and disassembly method is simple and convenient to use.

[0025] Specifically, the fastening cylinder 32 has a threaded portion 36 with external threads 35 on its outer surface at one end near the mounting cylinder 31. The end of the mounting cylinder 31 is recessed inward to form a threaded groove 37, which has internal threads 38. When the threaded portion 36 is fitted into the threaded groove 37, the outer surface of the mounting cylinder 31 is flush with the outer surface of the fastening cylinder 32. Thus, after assembly, no obvious stepped structure is formed on the surface of the mounting assembly 3.

[0026] Preferably, the clamping member 33 is connected end to end in a ring shape. This ensures that the clamping force formed by the clamping member 33 pressing against the stirring rod 1 is evenly distributed.

[0027] Preferably, two fastening cylinders 32 are provided and symmetrically connected to both sides of the mounting cylinder 31. This ensures that the fastening force is evenly distributed at both ends of the mounting cylinder 31, making the installation more stable and reliable.

[0028] Combination Figure 3 and Figure 4 As shown, a connecting sleeve 7 is fixedly provided on the side of the mounting component 3. The connecting sleeve 7 extends radially along the mounting component 3. One end of the blade 4 is fitted inside the connecting sleeve 7 and connected to the connecting sleeve 7 through a mounting hole 8. The mounting hole 8 is provided on the connecting sleeve 7 and the blade 4, and there are several mounting holes 8 arranged at equal intervals along the length direction of the blade 4. The mounting holes 8 that cooperate with each other can be selected as needed, thereby controlling the actual length of the blade 4 extending beyond the connecting sleeve 7, thus adapting to different stirring requirements and expanding the applicable scenarios.

[0029] Preferably, a plurality of connecting sleeves 7 are provided and evenly distributed along the circumference of the mounting assembly 3. The evenly distributed connecting sleeves 7 ensure the uniform distribution of the blades 4, making the stirring process of the stirring rod 1 more stable.

[0030] Combination Figure 4 and Figure 6 As shown, the blade 4 has a first through hole 41 and a second through hole 42 on its two sides, respectively. The first through hole 41 and the second through hole 42 are interconnected, with the first through hole 41 being horizontally positioned and the second through hole 42 being inclined downwards. The blade 4 of this invention also has a first through hole 41 and a second through hole 42, wherein the second through hole 42 is inclined downwards. This allows some of the solution to flow along the axis of the stirring rod 1 through the first through hole 41 and the second through hole 42 during stirring, thereby enhancing the uniformity of mixing along the axis of the stirring rod 1 and further improving the stirring effect.

[0031] like Figure 4 As shown, the thickness of the blade 4 at the end closest to the mounting assembly 3 is greater than the thickness at the end furthest from the mounting assembly 3. This tapering design distributes stress more evenly from the root to the tip, avoiding excessive stress concentration at the root, thus significantly improving the fatigue strength and overall structural reliability of the blade 4 and extending its service life. The tip of the blade 4 has the highest linear velocity, and its mass contributes the most to centrifugal force and moment of inertia. Thinning the tip also effectively reduces the overall weight of the blade 4.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0033] Although this document frequently uses terms such as stirring rod 1, impeller unit 2, mounting assembly 3, blade 4, guide groove 5, guide block 6, connecting sleeve 7, mounting hole 8, mounting cylinder 31, fastening cylinder 32, clamping part 33, clamping ring 34, external thread 35, threaded part 36, threaded groove 37, internal thread 38, first through hole 41, and second through hole 42, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
