Description

Technical Field

[0001] The invention belongs to the technical field of liquid material mixing, and in particular relates to a liquid material mixing device for the production of daily chemical products. Background Art

[0002] Daily chemicals refer to daily chemicals, which are scientific and technological chemical products used by people in daily life, including shampoo, shower gel, skin care, hair care, cosmetics, washing powder, etc.; and emulsified cosmetic material compositions can contain both oil phase and water phase, and the advantages of both can be achieved, so they are widely used as cosmetics. Therefore, in the production of emulsified cosmetics, it is an essential step to stir and emulsify the oil phase and the water phase, so a material mixing device is required;

[0003] The existing mixing and emulsification of the oil phase and the water phase of cosmetics is mostly carried out by putting the oil phase and the water phase into a high-speed mixer, and then stirring and mixing the oil phase and the water phase through the cooperation of the high-speed rotating stirring shaft and the stirring rod. Since water is a polar solvent and oil is a non-polar solvent, the interaction force between polar molecules is strong, while the interaction force between non-polar molecules is weak, and there is a large surface tension between water and oil, which causes them to form layers when they come into contact. Therefore, it is difficult to quickly stir and mix the incompatible oil phase and water phase using the existing mixer. Summary of the invention

[0009] Furthermore, the swing support assembly also includes an elastic sealing membrane, and the swing gaps between the shear blades and the arc-shaped swing grooves that are symmetrically offset up and down are all connected with segmented elastic sealing membranes.

[0010] Furthermore, the filling assembly includes a bearing, an annular filling box and a filling elbow. A plurality of flow slots are provided in a circumferential array on the tubular stirring shaft, and bearings are symmetrically installed on the upper and lower sides of the flow slots on the stirring shaft. An annular filling box is sealably installed on the outer ring of the bearing symmetrically. The outer box wall of the annular filling box is connected to a filling elbow, and the other end of the filling elbow extends upward from the outside of the mixing tank.

[0011] Furthermore, the filling assembly also includes an emulsification duct, and a plurality of the emulsification ducts are arranged in the gap between two adjacent arc-shaped swing grooves. One end of the emulsification duct is connected to a port of the ellipsoidal sac, and the other end of the emulsification duct is flush with the outer ring surface of the wheel disc. An electromagnetic valve body is provided on the emulsification duct.

[0012] Furthermore, an annular sealing ring is fitted at the connection between the upper and lower sections of the mixing tank, and a plurality of shear scrapers are installed in a circular array on the lower surface of the annular sealing ring. The inner end faces of the plurality of shear scrapers are in contact with the inner wall surface of the mixing tank, and the outer end faces thereof are provided with a plurality of shear grooves in the extended length direction.

[0013] Furthermore, the annular sealing ring is rotatably arranged at the connection between the upper and lower sections of the mixing tank, a sleeve ring is insulatedly sleeved on the stirring shaft above the uppermost wheel, and a plurality of long metal rods are installed in a circular array on the outer ring surface of the sleeve ring, a magnetic ring is insulatedly installed on the inner ring surface of the annular sealing ring, and the inner wall surface of the magnetic ring is in contact with the ends of the plurality of long metal rods.

[0016] 1. The present invention arranges symmetrical shear blades that are staggered up and down in a plurality of arc-shaped swing grooves opened on the outer ring of the wheel disc. The symmetrical shear blades, under the high-speed drive of the wheel disc, will generate high-speed rotating shear force and stirring force in the mixing tank, which can break the oil droplets of the oil phase into extremely fine droplets and disperse them into the water phase, so that the oil phase and the water phase can be quickly mixed and emulsified in the mixing tank.

[0017] 2. The swing support assembly can adjust the angle of the upper and lower symmetrical shear blades, so that the high-speed rotating shear blades can generate shear forces of different sizes in the mixing tank, thereby breaking up the oil phase into oil droplets of different sizes, so that the oil phase and the water phase can be quickly stirred and emulsified. Therefore, there is no need for the operator to manually remove the blades on the impeller disk from the mixing tank and then disassemble it to adjust the angle of the upper and lower crossed blades. Changing the shear force in the tank body will not only affect the production efficiency of the emulsified cosmetics, but also avoid pollution and damage to the normally produced emulsified cosmetics due to frequent opening of the mixing tank and frequent disassembly of the impeller disk on the stirring shaft.

[0018] 3. The present invention arranges a plurality of shear scrapers on the inner wall of the mixing tank. The rotation of the stirring shaft drives the plurality of shear scrapers to rotate in the mixing tank through the sleeve ring, the metal long rod and the annular sealing ring, so that the shear groove can form a high-speed rotating shear force to fully stir and mix the water phase and the oil phase; and when the emulsion formed by the mixture is discharged through the discharge conduit below, the stirring shaft can be controlled to rotate slowly, and the plurality of fitted shear scrapers can quickly scrape and clean the mixed emulsion adhered to the inner wall of the mixing tank; at the same time, when the mixing tank needs to be cleaned, the filling component can inject a cleaning solution into the mixing tank. Therefore, the rotation of the wheel disc can spray the cleaning solution sprayed from the emulsification conduit onto the inner wall of the mixing tank over a large area, and the cooperation with the rotating shear scraper can fully and quickly clean the residual emulsion adhered to the inner wall of the mixing tank.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0039] See also Figure 1-Figure 7 As shown, the present invention is a liquid material mixing device for daily chemical product production, comprising a split mixing tank 1, the upper portion of the mixing tank 1 is connected with an oil phase conduit 11 and a water phase conduit 12, and the bottom portion thereof is connected with a discharge conduit 13, a stirring shaft 2 is rotatably inserted in the mixing tank 1, and the top end of the stirring shaft 2 is connected to the output shaft of a servo motor fixed on the top of the mixing tank 1 through a coupling;

[0040] The stirring shaft 2 is provided with a plurality of wheels 3 along its length, and a plurality of arc-shaped swing grooves 31 are arranged in a circumferential array on the outer ring surface of each wheel 3, and a shearing blade 4 is installed in each arc-shaped swing groove 31 with a symmetrical shearing blade 4 staggered up and down;

[0041] A swing support assembly 5 is provided in each of the arc-shaped swing grooves 31, and the swing support assembly 5 is used to adjust the angle of the shear blades 4 that are symmetrically displaced up and down;

[0042] Specifically, the present invention installs a plurality of wheel discs 3 on the stirring shaft 2, and each wheel disc 3 is provided with a plurality of shear blades 4 in a circular array which can be angled and symmetrically staggered up and down. After the oil phase and the water phase are respectively introduced into the mixing tank 1 through the oil phase conduit 11 and the water phase conduit 12, the stirring shaft 2 in the mixing tank 1 is driven to rotate at a high speed by a servo motor and a coupling, and then the plurality of wheel discs 3 can drive the plurality of groups of shear blades 4 in the circular array of the layers to rotate at a high speed in the mixing tank 1, and then the shear blades 4 symmetrically staggered up and down generate a high-speed rotating shear force and stirring force in the mixing tank 1, which can break the oil droplets of the oil phase into extremely fine droplets and disperse them into the water phase, so that the oil phase and the water phase can be quickly mixed and emulsified in the mixing tank 1, and the observer can observe the internal oil phase and the water phase being mixed and emulsified through the observation window on the mixing tank 1. The state of the mixture is then controlled by controlling the operation of the swing support assembly 5 in the arc-shaped swing groove 31, so that the angle between the multiple shear blades 4 in the circular array that are symmetrically offset up and down can be automatically adjusted, so that the high-speed rotating shear blades 4 can generate shear forces of different sizes in the mixing tank 1, so that the oil phase can be broken up into oil droplets of different sizes, so that the oil phase and the water phase can be quickly stirred, mixed and emulsified, and thus there is no need for the operator to manually remove the blades on the impeller disk 3 from the mixing tank 1 and then disassemble it to adjust the angle of the upper and lower crossed blades. Changing the shear force in the tank body will not only affect the production efficiency of the emulsified cosmetics, but also avoid pollution and damage to the normally produced emulsified cosmetics due to frequent opening of the mixing tank 1 and frequent disassembly of the impeller disk 3 on the stirring shaft 2.

[0043] In the scheme designed in this embodiment, the swing support assembly 5 includes an arc tube 51, an arc shaft rod 52, a support side plate 53, an elliptical capsule 54, a spring member 55 and a flow guide square tube 56. The arc tube 51 is fixed on the wall surface corresponding to the two shear blades 4 that are symmetrically offset up and down, and the pipe openings of the two arc tubes 51 are aligned. The arc swing groove 31 is installed with an arc shaft rod 52 near the groove opening, and the arc shaft rod 52 is rotatably sleeved with two arc tubes 51 with aligned pipe openings. The inner end portions of the two shear blades 4 that are symmetrically offset up and down are integrally formed with support side plates 53, and the other end portions of the support side plates 53 extend to the non-connected At the side of the shear blade 4 connected to the support side plate 53, an ellipsoidal capsule 54 is connected between the inner ends of the two shear blades 4 integrally formed with the support side plate 53, and a plurality of spring members 55 are vertically arranged in the ellipsoidal capsule 54. A guide square tube 56 is fixed at the radial groove bottom of the arc-shaped swing groove 31. One end of the guide square tube 56 is connected to the ellipsoidal capsule 54, and the other end of the guide square tube is connected to the tubular stirring shaft 2. A filling component 6 is provided on the outer tube wall of the top end of the tubular stirring shaft 2. The filling component 6 is used to inject the fluid medium into the ellipsoidal capsule 54 through the stirring shaft 2 and the guide square tube 56, so that the ellipsoidal capsule 54 shrinks or expands.

[0044] Specifically, when it is necessary to increase the angle between the extended and symmetrically displaced shear blades 4, the fluid medium is introduced into the tubular stirring shaft 2 through the filling assembly 6, so that it enters into the multiple elliptical capsules 54 through the multiple flow-guiding square tubes 56. At this time, the multiple elliptical capsules 54 located at the bottom of the arc-shaped swinging groove 31 will expand vertically, and the internal spring member 55 will be stretched, so that the supporting side plates 53 at the inner ends of the crossed shear blades 4 will move away from each other, and the arc tubes 51 on the two shear blades 4 will rotate around the same arc-shaped shaft rod 52, so that the shear blades 4 extending out of the arc-shaped swinging groove 31 are close to each other, thereby increasing the angle between the two, thereby facilitating the reduction of the shear force between the two shear blades 4, so that the multiple shear blades 4 with increased angles can act as stirring rods in the mixing tank 1 to achieve rapid stirring, mixing and emulsification of the sheared oil phase and water phase; and when the angle between the two shear blades 4 is reduced, the filling assembly 6 is used to fill the mixing tank 1 with a plurality of fluid medium. The injection assembly 6 will extract the fluid medium inside the ellipsoidal sac 54, and the spring member 55 can shrink under its own elastic restoring force, so that the two supporting side plates 53 located inside the arc-shaped swinging groove 31 will approach each other, and at this time, the angle between the two shearing blades 4 extending out of the arc-shaped swinging groove 31 will be reduced, thereby facilitating the increase of the shear force between the two shearing blades 4, so that the two shearing blades 4 rotating at high speed can generate a larger shear force to shear the oil droplets of the oil phase into extremely small oil droplets, so that the oil phase can be more fully mixed into the water phase for emulsification, and a notch groove is formed between the shearing blades 4 corresponding to one supporting side plate 53 and the other supporting side plate 53, so that it will not interfere with the normal swing of the extended shearing blade 4, and the supporting side plate 53 and the inner end of the shearing blade 4 are integrally formed, so that the ellipsoidal sac 54 is stably and safely connected to the inner end of the shearing blade 4 located in the arc-shaped swinging groove 31, thereby realizing a stable and safe angle adjustment effect on the shearing blade 4.

[0045] In the scheme designed in this embodiment, the swing support assembly 5 also includes an elastic sealing membrane 57, and the swing gaps between the shear blades 4 and the arc-shaped swing grooves 31, which are symmetrically offset up and down, are connected with segmented elastic sealing membranes 57; specifically, the design of the elastic sealing membrane 57 can seal the sacrifice generated between the shear blades 4 and the arc-shaped swing grooves 31 to prevent the emulsion in the mixing tank 1 from entering the arc-shaped swing grooves 31, which will not only affect the normal swing of the shear blades 4, but also cause the emulsified emulsion to remain in the arc-shaped swing grooves 31 and cannot be discharged normally.

[0046] In the scheme designed in this embodiment, the filling assembly 6 includes a bearing 61, an annular filling box 62 and a filling elbow 63. A plurality of flow slots 21 are arranged in a circumferential array on the tubular stirring shaft 2, and the stirring shaft 2 is symmetrically mounted with bearings 61 on both sides of the flow slots 21. An annular filling box 62 is sealed and mounted on the outer ring of the upper and lower symmetrical bearing 61. The outer box wall of the annular filling box 62 is connected to the filling elbow 63, and the other end of the filling elbow 63 extends upward from the outside of the mixing tank 1.

[0047] Specifically, the filling port at the outer end of the filling elbow 63 is connected to the output pipe of the pump body, so that it transports the fluid medium to the annular filling box 62, and then injects it into the tubular stirring shaft 2 through multiple flow slots 21. The annular filling box 62 is rotatably connected to the stirring shaft 2 through upper and lower symmetrical bearings 61. Therefore, the high-speed rotation of the shear blade 4 driven by the stirring shaft 2 will not interfere with the annular filling box 62, and will not affect the annular filling box 62 to stably and safely add the fluid medium into the ellipsoidal sac 54 to cause it to expand.

[0048] In the scheme designed in this embodiment, the filling assembly 6 also includes an emulsification conduit 64, and a plurality of the emulsification conduits 64 are arranged in the gap between two adjacent arc-shaped swing grooves 31, and one end of the emulsification conduit 64 is connected to one end of the ellipsoidal sac 54, and the other end of the emulsification conduit is flush with the outer ring surface of the wheel disc 3, and the emulsification conduit 64 is provided with a solenoid valve body;

[0049] Specifically, in order to further accelerate the rapid stirring, mixing and emulsification of the water phase and the oil phase, the operator can replace the fluid medium with a liquid surfactant that can be used for emulsified cosmetics as needed, and inject it into the tubular stirring shaft 2 through the filling elbow 63 and the annular filling box 62, and then inject it into the multiple oval capsules 54 through multiple guide square tubes 56. At this time, the micro electromagnetic valve body on the emulsification conduit 64 is opened, so that the surfactant in the oval capsule 54 will enter the mixing tank 1 through the emulsification conduit 64. At the same time, the high-speed rotating wheel 3 will have a centrifugal spraying effect on the injected surfactant, thereby increasing the spraying area of ​​the surfactant in the mixing tank 1, so that the sprayed surfactant can fully reduce the surface tension of the oil phase and the water phase, and the two can be fully mixed and emulsified;

[0050] The operator can make the angle between the shear blades 4 shrink or expand when the surfactant is added to the mixing tank 1 as needed. If the angle of the shear blades 4 is to be expanded, the micro-electromagnetic valve on the emulsification conduit 64 can be closed first, and the liquid surfactant can be first allowed to enter the ellipsoid 54, so that the ellipsoid 54 first expands vertically, so that the angle between the two shear blades 4 increases, and then the micro-electromagnetic valve is opened. Since the diameter of the emulsification conduit 64 is smaller than the diameter of the guide square tube 56, the surfactant entering the emulsification conduit 64 through the ellipsoid 54 will not cause too much interference with the expansion size of the ellipsoid 54, thereby facilitating the increase and adjustment of the angle of the shear blades 4; and if the angle of the shear blades 4 is to be reduced, the micro-electromagnetic valve is opened before the surfactant is injected, so that the ellipsoid 54 only serves to connect the guide square tube 56 and the emulsification conduit 64, and the surfactant entering the ellipsoid 54 will not cause the ellipsoid 54 to expand greatly, thereby facilitating the control of the angle of the shear blades 4 to be in a reduced state.

[0051] In the scheme designed in this embodiment, the connection of the upper and lower sections of the mixing tank 1 is fitted with an annular sealing ring 7, and a plurality of shearing scrapers 8 are installed in a circumferential array on the lower surface of the annular sealing ring 7. The inner end surfaces of the plurality of shearing scrapers 8 are in contact with the inner wall surface of the mixing tank 1, and the outer end surfaces thereof are provided with a plurality of shearing grooves 81 in the extended length direction.

[0052] Specifically, when the stirring shaft 2 drives the shear blade 4 to rotate at a high speed in the mixing tank 1, the mixed oil phase and water phase will also flow synchronously in the mixing tank 1. Therefore, the shear grooves 81 provided on the multiple shear scrapers 8 vertically arranged on the inner wall of the mixing tank 1 can also shear the oil phase, so that the effect of stirring and mixing the oil phase and the water phase can be further improved. Since the vertical shear scraper 8 is supported and installed by the annular sealing ring 7, it will not interfere with the normal use of other components inside the mixing tank 1. The initial state of the shear scraper 8 is staggered with the oil phase conduit 11 and the water phase conduit 12, so that it will not interfere with the normal entry of the oil phase and the water phase into the mixing tank 1.

[0053] In the scheme designed in this embodiment, the annular sealing ring 7 is rotatably arranged at the connection of the upper and lower sections of the mixing tank 1, and a sleeve ring 22 is insulatedly sleeved on the stirring shaft 2 located above the uppermost wheel disc 3, and a plurality of metal long rods 9 are installed in a circumferential array on the outer ring surface of the sleeve ring 22, and a magnetic attraction ring 71 is insulatedly installed on the inner ring surface of the annular sealing ring 7, and the inner wall surface of the magnetic attraction ring 71 contacts the ends of the plurality of metal long rods 9;

[0054] Specifically, when the stirring shaft 2 rotates at a high speed, the multiple electromagnet blocks arranged on the inner ring surface of the magnetic attraction ring 71 can be controlled to be energized as needed, so that the magnetic attraction ring 71 has a magnetic attraction force to adsorb and fix the multiple metal long rods 9, and then the rotation of the stirring shaft 2 will drive the multiple shear scrapers 8 to rotate in the mixing tank 1 through the sleeve ring 22, the metal long rod 9, and the annular sealing ring 7, so that the shear groove 81 can form a high-speed rotating shear force to fully stir and mix the water phase and the oil phase; and when the mixed emulsion is discharged through the discharge conduit 13 below, the stirring shaft 2 can be controlled to rotate slowly at this time, and the multiple fitted shear scrapers 8 can quickly scrape and clean the mixed emulsion adhered to the inner wall of the mixing tank 1; at the same time, when the mixing tank 1 needs to be cleaned, the filling component 6 can inject a cleaning solution into the mixing tank 1, so that the rotation of the wheel disc 3 can spray the cleaning solution sprayed from the emulsification conduit 64 on the inner wall of the mixing tank 1 over a large area, and cooperate with the rotating shear scraper 8 to fully and quickly clean the residual emulsion adhered to the inner wall of the mixing tank 1.

[0055] In the scheme designed in this embodiment, the bottom ends of the multiple shear scrapers 8 are connected to the arc-shaped scraper strips 82, and the multiple arc-shaped scraper strips 82 are attached to the inner wall surface of the arc-shaped tank bottom of the mixing tank 1, and the bottom ends of the multiple arc-shaped scraper strips 82 extend to the pipe mouth of the discharge duct 13; specifically, the rotation of the shear scraper 8 can drive the arc-shaped scraper strips 82 to rotate on the bottom of the mixing tank 1, so as to scrape and discharge or clean the emulsion adhered to the arc-shaped tank bottom of the mixing tank 1.
