Description

Technical Field

[0001] This invention relates to the field of dynamic membrane production equipment technology, specifically a dynamic membrane emulsification and homogenization device. Background Technology

[0002] Dynamic membrane emulsification homogenizers are a new type of fluid processing equipment based on the synergistic effect of dynamic membrane separation and mechanical homogenization. They are widely used in food, pharmaceuticals, coatings, nanomaterials and other fields. The core principle is to form a stable hydrodynamic environment on the membrane surface by rotating or vibrating the dynamic membrane module. Under the action of membrane pore shearing, mechanical impact or pressure difference, the raw materials to be processed achieve uniform dispersion and emulsification of oil phase, water phase and solid particles, and finally form a homogenized product with concentrated particle size distribution and strong stability. With its efficient emulsification effect, mild processing environment and flexible operation, this type of equipment is gradually becoming a key equipment to replace traditional high pressure homogenizers and colloid mills. It is especially suitable for the processing of heat-sensitive, high-viscosity or active ingredients.

[0003] Early dynamic membrane emulsification homogenizing devices mainly consisted of a fixed membrane module, a single stirring blade, and a drive motor. The membrane module was fixed inside the equipment cavity, and the material flow was driven by the rotation of the stirring blade, allowing the material to pass through the membrane pores to achieve emulsification. However, this type of structure has significant drawbacks: on the one hand, the flow field distribution generated by the stirring blade is uneven, resulting in large differences in the probability of material contact with the membrane surface, and material retention in some areas, ultimately leading to poor particle size uniformity in the emulsion; on the other hand, the shearing strength of a single membrane pore is limited, making it difficult to break up agglomerated particles in high-viscosity materials, and the fixed membrane surface is easily blocked by particles, requiring frequent shutdowns for cleaning, which seriously affects production efficiency. To solve the above problems, existing technologies have gradually adopted a composite structure of "dynamic membrane + multiple shear units". By setting up a rotating membrane cylinder, multi-layer stirring blades, or ultrasonic auxiliary modules, the turbulence and shearing effect of the material are enhanced. At the same time, some devices have added a backflushing cleaning structure to reduce the risk of membrane fouling.

[0004] However, existing devices still have core shortcomings: existing devices mostly achieve membrane contact by pushing materials in one direction, which makes it difficult to form directional collisions and thorough mixing of materials, resulting in a single emulsion level and incomplete breakup of large droplets; in addition, existing defoaming structures are mostly independent defoaming modules, which are set separately from the emulsification unit. After emulsification, the material needs to flow through the defoaming module, which not only increases the size of the equipment, but also causes emulsion stratification due to secondary flow. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a dynamic membrane emulsification homogenization device that solves the problems of inability to form directional collisions and sufficient mixing, resulting in a single emulsion level, incomplete breakup of large droplets, and affecting the uniformity of emulsion particle size.

A limiting slider is slidably connected to the outside of each slide rail cylinder. A rhombic quadrilateral support frame is rotatably connected to the top of the limiting slider. A C-shaped clamping plate is fixedly connected to the bottom end of the rhombic quadrilateral support frame away from the limiting slider. Connecting plates are rotatably connected to both sides of the top of the rhombic quadrilateral support frame. A lead screw is rotatably connected to the middle of one connecting plate. The outer wall of the lead screw is threadedly connected to the connecting plate on the other side. A fixing bolt is threadedly connected to the outside of the limiting slider.

[0009] Preferably, the height adjustment mechanism includes a limiting block, which is fixedly connected to the outside of the rotating shaft. A limiting notch is formed on the outside of the sleeve, and the limiting block is slidably connected to the middle of the limiting notch. A threaded groove is formed at the top of the outer wall of the sleeve, and multiple anti-slip protrusions are fixedly connected to the inner wall of the sleeve. Multiple contraction slits are formed at the top of the sleeve, and a spiral extrusion cap is provided at the top of the sleeve. The outer wall of the spiral extrusion cap is threadedly connected to the inner wall of the threaded groove.

[0010] Preferably, the outer wall of the rotating shaft penetrates the top end of the support sleeve, multiple inclined guide tubes are evenly distributed along the circumferential direction of the limiting disc, and multiple I-shaped beaters are evenly distributed along both the axial and circumferential directions of the sleeve.

[0011] Preferably, the inner diameter of the conical hole is larger than the outer diameter, and the conical holes of the hole sleeve are evenly distributed along its circumference and axial direction.

[0012] Preferably, one end of the fixing bolt passes through the limiting slider and abuts against the slide rail cylinder, and the rhomboid quadrilateral support frame is composed of four connecting rods that are rotatably connected end to end, and the four connecting rods are of the same length.

[0013] Preferably, one end of the lead screw is fixedly connected to a rotating handle, and the outer wall of the rotating handle is provided with anti-slip protrusions.

[0014] Preferably, the length of the limiting notch is set along the axial direction of the sleeve, the anti-slip protrusion is in contact with the rotating shaft, and the anti-slip protrusion is made of rubber.

[0015] Preferably, the length of the threaded groove is set along the axial direction of the sleeve, the number of threaded grooves is adapted to the number of contraction joints, and the contraction joints extend along the axial direction of the sleeve to the bottom end of the threaded groove.

[0016] Preferably, the fixing column and the slide rail cylinder are equidistantly distributed along the circumference of the support sleeve, the diameter of the limiting disk is smaller than the inner diameter of the hole sleeve, and a gap is left between the top end of the I-shaped plate and the bottom end of the limiting disk.

[0017] This invention provides a dynamic membrane emulsification homogenization device. It has the following beneficial effects:

[0018] 1. This invention drives a rotating shaft to rotate via a drive motor. The sleeve connected by the height adjustment mechanism rotates synchronously. The limiting disc drives the inclined guide tube to generate centrifugal suction, which draws in the upper liquid and guides it to the bottom. At the same time, the shaftless auger pushes the bottom liquid upward, causing the upper and lower liquids to collide and mix in the middle. The I-shaped beater beats and disperses the liquid and pushes it outward. When the liquid passes through the conical hole of the perforated sleeve, the bubbles are squeezed and broken, achieving emulsification, homogenization and defoaming.

[0019] 2. This invention uses rotating the fixing bolt to disengage the limiting slider from the slide rail cylinder, moves the slider to adjust the position of the rhomboid support frame, aligns the C-shaped clamping plate with the edge of the mixing drum, and then tightens the bolt to clamp the clamping plate on the top of the drum. Rotating the screw causes the connecting plate to extend and retract the rhomboid support frame, making the clamping plate tightly adhere to the drum wall. To disassemble, loosen the bolt and move the slider to remove the clamping plate from the drum wall, thus achieving quick adaptation to mixing drums of different specifications.

[0020] 3. In this invention, the spiral extrusion cap is first rotated to move it upward and detach it from the sleeve, the shrinkage seam is reset, the anti-slip protrusion separates from the rotating shaft, and the fixation is released. Then, the limiting disc or sleeve is held and moved up and down along the rotating shaft, the limiting notch slides along the limiting block to restrict the direction of movement and prevent deviation. After adjusting to a suitable height, the spiral extrusion cap is rotated in the opposite direction to move it downward and press it against the sleeve, causing the anti-slip protrusion to abut against the rotating shaft, thus completing the fixation and realizing height adjustment.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 4 and attached Figure 6 This invention provides a dynamic membrane emulsification homogenizing device, including a support sleeve 1 and a limiting disk 5. A drive motor 7 is fixedly connected to the top end of the support sleeve 1, and a rotating shaft 6 is fixedly connected to the output end of the drive motor 7. A mixing and debubbling mechanism 2 is provided on the outer side of the limiting disk 5. The mixing and debubbling mechanism 2 is used to quickly mix the raw materials and eliminate large bubbles generated during mixing. A support clamping and fixing mechanism 3 is provided on the outer wall of the support sleeve 1. The support clamping and fixing mechanism 3 is used to adapt to the fixed installation of mixing cylinders of different specifications. A height adjustment mechanism 4 is provided on the outer wall of the rotating shaft 6. The height adjustment mechanism 4 is used to adjust the position of the mixing mechanism in the liquid according to the mixing volume.

[0032] The mixing de-bubbling mechanism 2 includes multiple inclined guide tubes 21, all of which pass through the middle of the limiting disk 5. A sleeve 22 is fixedly connected to the bottom end of the limiting disk 5. The sleeve 22 is sleeved on the outside of the rotating shaft 6. Multiple I-shaped clasps 23 are fixedly connected to the outside of the sleeve 22. An inclined groove 24 is opened on the lower middle side of the outer wall of the sleeve 22. A shaftless auger 25 is fixedly connected to the outside of the sleeve 22. Multiple fixing posts 26 are fixedly connected to the bottom end of the supporting sleeve 1. A hole sleeve 27 is fixedly connected to the bottom end of each of the multiple fixing posts 26. The hole sleeve 27 has a conical hole.

[0033] The outer wall of the rotating shaft 6 penetrates the top of the supporting sleeve 1, ensuring stable rotation of the rotating shaft 6 and efficient power transmission to the lower components; multiple inclined guide tubes 21 are evenly distributed along the circumference of the limiting disk 5, making the upper liquid intake more uniform and ensuring the consistency of collision mixing; multiple I-shaped beaters 23 are evenly distributed along the axial and circumferential directions of the sleeve 22, realizing all-round beating and dispersing of the liquid, improving the emulsification uniformity; the inclined grooves 24 are spirally distributed along the outer wall of the sleeve 22, enhancing the axial transport and turbulence effect of the liquid and avoiding local stagnation; the inner diameter of the conical hole is larger than the outer diameter, causing large air bubbles to burst under compression, achieving efficient de-bubbling; the conical holes of the perforated sleeve 27 are evenly distributed along its circumference and axial direction, ensuring that the liquid is subjected to consistent force when flowing through, and the de-bubbling and shearing effects are balanced;

[0034] Specifically, the drive motor 7 at the top of the support sleeve 1 is activated. The output of the drive motor 7 drives the rotating shaft 6 to rotate around its own axis. Since the sleeve 22 is fixed to the rotating shaft 6 through the height adjustment mechanism 4, and the limiting notch 42 and the limiting block 41 cooperate to restrict relative rotation, the sleeve 22 rotates synchronously with the rotating shaft 6. The limiting disk 5 at the top of the sleeve 22 rotates synchronously, driving the multiple inclined guide tubes 21 connected to the top to rotate. During the rotation, the inclined guide tubes 21 generate centrifugal force and suction, drawing the upper layer of liquid in the stirring drum from the top into the tube and guiding it along the inclined direction to the bottom to impact the middle area. At the same time, the shaftless auger 25 at the bottom of the sleeve 22 rotates with the sleeve 22, using the spiral structure to push the bottom layer of liquid in the stirring drum upward. The liquid is pushed towards the middle area, causing the upper liquid to collide with the lower liquid in the middle area, achieving initial mixing. Multiple I-shaped patters 23 on the middle of the outer wall of the sleeve 22 rotate with the sleeve 22, patting and dispersing the liquid after the collision in the middle area, while pushing the liquid to the surrounding areas. The pushed liquid flows outward and enters the perforated sleeve 27 fixed at the bottom end of the support sleeve 1 by the fixing column 26. When the liquid passes through the conical hole on the perforated sleeve 27, because the inner diameter of the conical hole is larger than the outer diameter, the large air bubbles in the liquid are squeezed by the hole wall as they pass through the gradually narrowing hole and burst. Finally, the liquid with fine air bubbles flows out from the outside of the conical hole, completing the entire emulsification, homogenization and de-bubbling process.

[0035] See appendix Figure 1 Appendix Figure 2 and attached Figure 5 The support clamping and fixing mechanism 3 includes multiple slide rail cylinders 31. The multiple slide rail cylinders 31 are equidistantly fixed to the outside of the support sleeve 1 near one end. A limiting slider 32 is slidably connected to the outside of the slide rail cylinders 31. A rhomboid quadrilateral support frame 33 is rotatably connected to the top of the limiting slider 32. A C-shaped clamping plate 34 is fixedly connected to the bottom end of the rhomboid quadrilateral support frame 33 away from the limiting slider 32. Connecting plates 35 are rotatably connected to both sides of the top of the rhomboid quadrilateral support frame 33. A lead screw 36 is rotatably connected to the middle of one side of the connecting plate 35. The outer wall of the lead screw 36 is threadedly connected to the other side of the connecting plate 35. A fixing bolt 37 is threadedly connected to the outside of the limiting slider 32.

[0036] One end of the fixing bolt 37 passes through the limiting slider 32 and abuts against the slide rail cylinder 31, achieving quick locking and unlocking of the limiting slider 32 through direct abutment, making operation convenient; the rhomboid quadrilateral support frame 33 is composed of four connecting rods that rotate end to end, and the four connecting rods are of the same length, ensuring symmetrical and stable telescopic movement of the support frame and improving the force balance during fixing; one end of the lead screw 36 is fixedly connected to a rotating handle, providing a convenient force application point for the rotation of the lead screw 36 and reducing the difficulty of operation; the outer wall of the rotating handle is provided with anti-slip protrusions to increase the friction between the hand and the handle and prevent slippage during rotation;

[0037] Specifically, place the entire device directly above the mixing drum containing the raw materials to be mixed, ensuring that the support sleeve 1 is coaxial with the mixing drum. Then, rotate the fixing bolt 37 on the outside of the limiting slider 32 to disengage the fixing bolt 37 from the outer wall of the slide rail cylinder 31, releasing the lock between them. Next, move the limiting slider 32 axially along the slide rail cylinder 31, causing the top rhomboid quadrilateral support frame 33 to move synchronously. Adjust until the C-shaped clamping plate 34 can be engaged with the top edge of the mixing drum. Then, retighten the fixing bolt 37 to fix the limiting slider 32 to the slide rail cylinder 31. Finally, move the C-shaped clamping plate 34... The opening faces the mixing drum wall and is locked onto the top of the mixing drum. Rotating the handle at one end of the lead screw 36 causes the lead screw 36 to move the two adjacent connecting plates 35 closer or further apart, thereby pushing the connecting rod of the rhomboid quadrilateral support frame 33 to rotate, realizing the extension and retraction of the rhomboid quadrilateral support frame 33. This allows the inner wall of the C-shaped clamping plate 34 to be tightly pressed against the mixing drum wall, thus fixing the device to the mixing drum. When it is necessary to disassemble the device, rotate the fixing bolt 37 in the opposite direction to unlock it. Slightly move the limiting slider 32 and the rhomboid quadrilateral support frame 33 to disengage the C-shaped clamping plate 34 from the mixing drum wall, and then the device can be removed from the top of the mixing drum.

[0038] See appendix Figure 3 Appendix Figure 4 Appendix Figure 7 and attached Figure 8 The height adjustment mechanism 4 includes a limiting block 41, which is fixedly connected to the outside of the rotating shaft 6. A limiting notch 42 is opened on the outside of the sleeve 22. The limiting block 41 is slidably connected to the middle of the limiting notch 42. A threaded groove 43 is opened at the top of the outer wall of the sleeve 22. Multiple anti-slip protrusions 44 are fixedly connected to the inner wall of the sleeve 22. Multiple contraction slots 45 are opened at the top of the sleeve 22. A spiral extrusion cap 46 is provided at the top of the sleeve 22. The outer wall of the spiral extrusion cap 46 is threadedly connected to the inner wall of the threaded groove 43.

[0039] The length of the limiting notch 42 is set along the axial direction of the sleeve 22, providing an effective stroke for the height adjustment of the sleeve 22 to adapt to different liquid volume requirements. The anti-slip protrusion 44 contacts the rotating shaft 6, increasing the friction between the sleeve 22 and the rotating shaft 6 to prevent sliding and displacement after adjustment. The anti-slip protrusion 44 is made of rubber, which can tightly fit the rotating shaft 6 through elastic deformation, improving the fixing stability and preventing scratches on the rotating shaft 6. The length of the threaded groove 43 is set along the axial direction of the sleeve 22, providing sufficient adjustment stroke for the spiral extrusion cap 46 to ensure the shrinkage fixing effect. The number of threaded grooves 43 is matched with the number of shrinkage seams 45, so that the shrinkage of each area at the top of the sleeve 22 is uniform, avoiding local stress deformation. The shrinkage seam 45 extends along the axial direction of the sleeve 22 to the bottom of the threaded groove 43, ensuring that the top of the sleeve 22 can be flexibly shrunk, realizing quick fixing and unlocking with the rotating shaft 6.

[0040] Specifically, the required immersion height of the mixing and de-aeration mechanism 2 is determined based on the volume of the liquid to be mixed in the mixing drum. First, rotate the spiral extrusion cap 46 at the top of the outer wall of the sleeve 22, causing the spiral extrusion cap 46 to move upward along the threaded groove 43, gradually disengaging from the tight fit with the sleeve 22. At this time, the contraction seam 45 at the top of the sleeve 22 returns to its original position under its own elasticity, and the anti-slip protrusion 44 on the inner wall of the sleeve 22 disengages from the outer wall of the rotating shaft 6, releasing the fixation between the sleeve 22 and the rotating shaft 6. Then, hold the limiting disc 5 or the sleeve 22 and move it up and down along the axial direction of the rotating shaft 6. At this time, the limiting notch 42 on the outer wall of the sleeve 22 slides along the outer wall of the limiting block 41. The limiting block 41 restricts the movement direction and range of the sleeve 22 to prevent the sleeve 22 from rotating and shifting. When the height of the I-shaped plate 23 and the shaftless auger 25 can be adapted to the liquid volume, the spiral extrusion cap 46 is rotated in the opposite direction to move it down along the thread groove 43 and fit tightly against the outer wall of the sleeve 22. The top of the sleeve 22 is squeezed to shrink it, which causes the anti-slip protrusion 44 to re-abut against the outer wall of the rotating shaft 6, fixing the sleeve 22 and the rotating shaft 6, thus completing the height adjustment.

[0041] See appendix Figure 2 Appendix Figure 3 and attached Figure 6 The fixed column 26 and the slide rail column 31 are equidistantly distributed along the circumference of the support sleeve 1. The diameter of the limiting disk 5 is smaller than the inner diameter of the hole sleeve 27. A gap is left between the top of the I-shaped plate 23 and the bottom of the limiting disk 5.

[0042] Specifically, the fixed columns 26 and the slide rail cylinders 31 are equidistantly distributed along the circumference of the support sleeve 1, ensuring the symmetry and force balance of the support structure and avoiding spatial interference between different functional modules. The fixed columns 26, as the support carrier for the perforated sleeve 27, and their equidistant alternating distribution with the slide rail cylinders 31, allow the perforated sleeve 27 to form a stable annular support structure below the support sleeve 1, ensuring the coaxiality of the perforated sleeve 27 and the support sleeve 1. This, in turn, ensures uniform clearance of the I-shaped beater 23 when rotating inside the perforated sleeve 27, avoiding localized wear or obstruction of material flow due to eccentricity. Simultaneously, the symmetrically distributed fixed columns 26 can evenly transfer the weight of the perforated sleeve 27 to the support sleeve 1, improving the overall structural stability of the device and reducing vibration during high-speed rotation. The diameter of the limiting disc 5 is designed to be smaller than the inner diameter of the perforated sleeve 27, forming an annular channel structure, reserving sufficient space for the flow and mixing of the upper liquid. When the inclined guide tube 21 guides the upper liquid to the bottom for impact, the annular channel... This design avoids backflow or stagnation of liquid due to space constraints, ensuring smooth flow of liquid to the central collision area. Simultaneously, the annular gap between the limiting disk 5 and the perforated sleeve 27 allows the liquid pushed by the I-shaped beater 23 to quickly flow into the conical hole of the perforated sleeve 27, reducing flow resistance and improving the continuous efficiency of emulsification and de-bubbling. It also prevents uneven emulsification caused by localized liquid accumulation. A gap between the top of the I-shaped beater 23 and the bottom of the limiting disk 5 ensures the free rotation of the I-shaped beater 23, preventing mechanical interference with the limiting disk 5 and creating a localized turbulent mixing effect. When the I-shaped beater 23 rotates at high speed, a negative pressure suction is generated at the gap, continuously drawing the collided liquid into the beating area, preventing liquid stagnation at the bottom of the limiting disk 5. Simultaneously, the shear flow generated by the gap further breaks up fine droplets, improving the uniformity of emulsion particle size. Furthermore, it provides an escape channel for bubbles in the liquid, allowing them to smoothly enter the conical hole of the perforated sleeve 27 and be squeezed and broken, ensuring comprehensive de-bubbling effect.

[0043] Working principle: First, after the device is supported, fixed, and its height adjusted, the drive motor 7 at the top of the support sleeve 1 is activated. The output of the drive motor 7 drives the rotating shaft 6 to rotate around its own axis. Since the sleeve 22 is fixed to the rotating shaft 6 through the height adjustment mechanism 4, and the limiting notch 42 and the limiting block 41 restrict relative rotation, the sleeve 22 rotates synchronously with the rotating shaft 6. The limiting disk 5 at the top of the sleeve 22 rotates synchronously, driving the multiple inclined guide tubes 21 connected to the top to rotate. During the rotation, the inclined guide tubes 21 generate centrifugal force and suction, drawing the upper layer of liquid in the stirring drum from the top into the tube and guiding it along the inclined direction to the bottom to impact the middle area. At the same time, the shaftless auger 25 at the bottom of the sleeve 22 rotates with the sleeve 22, using the spiral structure to push the bottom layer of liquid in the stirring drum upward, causing the bottom layer of liquid to impact the middle area. The upper layer of liquid and the bottom layer of liquid interact in the middle area. The liquid undergoes initial mixing through collision. Multiple I-shaped plates 23 in the middle of the outer wall of the sleeve 22 rotate with the sleeve 22, striking and dispersing the liquid after the collision in the middle, while simultaneously pushing the liquid to the surrounding areas. The pushed liquid flows outward and enters the perforated sleeve 27 fixed at the bottom of the support sleeve 1 by the fixing column 26. When the liquid passes through the conical hole on the perforated sleeve 27, because the inner diameter of the conical hole is larger than the outer diameter, the large bubbles in the liquid are squeezed by the hole wall and burst when passing through the gradually narrowing hole. Finally, the liquid with fine bubbles flows out from the outside of the conical hole, completing the entire emulsification, homogenization and debubbling process. This achieves the synergistic effect of directional collision between upper and lower layers of materials, multi-stage emulsification and synchronous debubbling, solving the problems of single emulsification level, incomplete breakage of large droplets and emulsion stratification caused by debubbling and emulsification separation in existing devices, and improving the uniformity of emulsion particle size and processing efficiency.

[0044] Furthermore, using the support clamping and fixing mechanism 3, before using the device, first place the entire device directly above the mixing drum containing the raw materials to be mixed, ensuring that the support sleeve 1 is coaxial with the mixing drum. Then, rotate the fixing bolt 37 on the outside of the limiting slider 32 to disengage the fixing bolt 37 from the outer wall of the slide rail cylinder 31, releasing the lock between them. Then, move the limiting slider 32 along the axial direction of the slide rail cylinder 31, causing the top diamond-shaped four-sided support frame 33 to move synchronously. After adjusting the C-shaped clamping plate 34 to the position where it can be engaged with the top edge of the mixing drum, tighten the fixing bolt 37 again to fix the limiting slider 32 to the slide rail cylinder 31. Then, face the opening of the C-shaped clamping plate 34 towards the wall of the mixing drum and engage it with the top of the mixing drum. Rotate one end of the screw 36. By moving the handle, the lead screw 36 drives the two adjacent connecting plates 35 to move closer or further apart, thereby pushing the connecting rod of the rhomboid quadrilateral support frame 33 to rotate, realizing the extension and retraction of the rhomboid quadrilateral support frame 33. This allows the inner wall of the C-shaped clamping plate 34 to be tightly pressed against the wall of the mixing drum, thus fixing the device to the mixing drum. When it is necessary to disassemble the device, rotate the fixing bolt 37 in the opposite direction to unlock it. Slightly move the limiting slider 32 and the rhomboid quadrilateral support frame 33 to separate the C-shaped clamping plate 34 from the wall of the mixing drum, and the device can be removed from the top of the mixing drum. This achieves quick adaptation and stable fixation for mixing drums of different specifications. The operation is convenient and the disassembly is efficient. It solves the problems of the existing device having a single fixing method, poor adaptability, and cumbersome disassembly and assembly, and improves the versatility and flexibility of the device.

[0045] Simultaneously, through the height adjustment mechanism 4, after the device is supported and fixed, the required immersion height of the mixing and de-bubbling mechanism 2 is determined according to the volume of the liquid to be stirred in the mixing drum. First, rotate the spiral extrusion cap 46 at the top of the outer wall of the sleeve 22, so that the spiral extrusion cap 46 moves upward along the thread groove 43 and gradually disengages from the tight fit with the sleeve 22. At this time, the contraction seam 45 at the top of the sleeve 22 resets under its own elasticity, and the anti-slip protrusion 44 on the inner wall of the sleeve 22 disengages from the outer wall of the rotating shaft 6, releasing the fixation between the sleeve 22 and the rotating shaft 6. Then, hold the limiting disc 5 or the sleeve 22 and move it up and down along the axial direction of the rotating shaft 6. At this time, the limiting notch 42 on the outer wall of the sleeve 22 slides along the outer wall of the limiting block 41, and the limiting block 41... The movement direction and range of the sleeve 22 are restricted to prevent the sleeve 22 from rotating or deviating. After adjusting the height of the I-shaped plate 23 and the shaftless auger 25 to match the liquid volume, the spiral extrusion cap 46 is rotated in the opposite direction to move it downward along the threaded groove 43 and fit tightly against the outer wall of the sleeve 22. The top of the sleeve 22 is squeezed to shrink it, which causes the anti-slip protrusion 44 to re-abut against the outer wall of the rotating shaft 6, fixing the sleeve 22 and the rotating shaft 6. This completes the height adjustment, thereby achieving precise and convenient adjustment of the immersion height of the mixing and de-bubbling mechanism 2. After adjustment, it is fixed and stable, solving the problem that the height of the emulsification mechanism in the existing device is fixed or cumbersome to adjust and cannot be adapted to different liquid volumes, ensuring the stability of the emulsification homogenization effect under different processing volumes.
