Description

Technical Field

[0001] The present invention relates to the technical field of emulsifying equipment, and specifically to a microsphere emulsifying machine capable of preparing monodisperse microspheres. Background Art

[0002] In the field of microsphere preparation, the preparation technology of monodisperse microspheres (microspheres with high particle size uniformity) is of great significance to fields such as materials science, biomedicine, and chemical engineering.

[0003] Existing emulsifying machines mostly adopt a single-direction or single-layer stirring structure. The flow path of the material in the container is fixed, which easily forms stirring dead corners, resulting in uneven stress on the microspheres during emulsification and a wide range of particle size distribution. Moreover, the stirring components of traditional equipment can only achieve a single rotational motion and cannot simultaneously control the reciprocating swing of the stirring elements, making it difficult to form a shear force to achieve fine dispersion of the material, restricting the preparation precision of monodisperse microspheres. Therefore, it is necessary to develop a microsphere emulsifying machine capable of preparing monodisperse microspheres. Summary of the Invention

[0048] A screen 101 is fixedly arranged in the middle and lower part of the inner cavity of the housing 100;

[0049] The stirring and turning mechanism 200 is arranged inside the housing 100 and above the screen 101, and is used for stirring the materials in the housing 100 in all directions. The stirring and turning mechanism 200 includes a vertical main rotating rod 201 rotatably arranged at the center of the inner cavity of the housing 100. Two fixed platforms 202 are fixedly arranged on the outer side of the rod body of the main rotating rod 201. The two fixed platforms 202 are both circular plates and are respectively fixed in the middle and bottom of the rod body of the main rotating rod 201. The outer side walls of each fixed platform 202 are fixedly arranged in an equally spaced and circumferentially arranged manner around its own vertical axis with fixed frames 203. The cross-section of the fixed frame 203 in the top view direction is in the shape of "冂", and a swing rod 204 is rotatably arranged on the inner side wall of the fixed frame 203 through a bearing.

[0050] The driving mechanism 300 is provided on the housing 100 and the fixed platform 202, and is used to drive the fixed platform 202 to rotate, thereby driving all the blades 206 to rotate, and at the same time controlling each blade 206 to swing back and forth, with the blades 206 corresponding to the upper and lower layers swinging in opposite directions;

[0051] The top side of the housing 100 is provided with a feeding tube 102 connected to its own inner cavity, and the upper end of the feeding tube 102 is hingedly provided with a sealing cover. When injecting material, the sealing cover at the upper end of the feeding tube 102 is flipped upward. The sealing cover is connected by a hinge and has an opening angle of at least 90 degrees. The material is poured into the feeding tube 102 through a funnel, and the material is guided to the top of the screen 101 through the inner wall of the pipe. After the injection is completed, the sealing cover is pressed down to make it fit with the end face of the feeding tube 102. The bottom of the sealing cover is provided with a rubber sealing layer that is interference-fitted with the inner side of the feeding tube 102, and a seal is formed by a rubber sealing ring.

[0052] Among them, vertical legs 103 are fixedly provided around the bottom of the shell 100. The legs 103 are made of rectangular steel pipes, and adjustable feet are installed at the bottom to ensure that the equipment remains level under different ground flatness and avoid eccentric stirring due to shaking. The bottom of the shell 100 is provided with a discharge pipe 104 connected to its own inner cavity, and a discharge valve is provided on the discharge pipe 104; the discharge valve is a manual ball valve. When discharging, the manual ball valve on the discharge pipe 104 is rotated. The conical structure at the bottom of the shell 100 has a cone angle of not less than 60°, so that the material converges toward the center along the inner wall under the action of gravity and is discharged through the discharge pipe 104; the residual material can be cleaned through the material taking door 105;

[0053] Among them, the front side wall of the shell 100 is provided with a feeding port, and the front side wall of the shell 100 is hingedly provided with a feeding door 105 for sealing the feeding port, and a sealing layer is provided on the side of the feeding door 105 close to the feeding port, and a door lock and a door handle are provided on the feeding door 105; when inspecting or taking materials, the door lock can be opened, and the feeding door 105 can be pulled outward by the door handle to directly contact the area above the screen 101 to remove foreign objects; after the inspection or taking materials is completed, the feeding door 105 is closed and the door lock is closed, and the sealing layer fits tightly against the edge of the feeding port to reduce the accident of leakage.

[0054] In Example 2, based on Example 1, the driving mechanism 300 includes a circular opening 301 at the center of the top of the housing 100. A truncated cone-shaped rotating platform 302 is rotatably provided inside the opening 301 via a sealed bearing. A fixing hole 303 is provided in the center of the rotating platform 302 for the main rotating rod 201 to pass through.

[0055] A sun gear 304 is fixedly mounted on the upper outer end of the main rotating rod 201. Planetary gears 305 are arranged around the outer wall of the sun gear 304 at equal intervals, centered on the sun gear 304. All the planetary gears 305 are always engaged with the sun gear 304, and the number of the planetary gears 305 is the same as the number of blades 206 on each layer.

[0056] A vertical follower rod 306 is fixedly provided at the center of the bottom wall of each planetary gear 305. The rod body of the follower rod 306 rotates through the upper and lower surfaces of the rotating platform 302 through a bearing.

[0057] An annular fixing ring 307 is fixedly provided on the top of the housing 100, outside the planetary gears 305. A circle of fixed internal teeth 308 is fixedly provided on the inner wall of the fixing ring 307. The fixed internal teeth 308 are always engaged with all the planetary gears 305. The meshing transmission between the sun gear 304 and the planetary gears 305 drives the follower rod 306 to rotate synchronously to transmit power. The planetary gear transmission 305 structure realizes power diversion, ensuring the synchronous movement of multiple sets of blades 206.

[0058] The inner cavity of each fixed platform 202 is provided with an annular mounting groove 309. The lower end of each follower rod 306 rotates through the inner top wall of the upper mounting groove 309 via a sealed bearing. The lower end of each follower rod 306 is fixedly provided with a first bevel gear 310. All the first bevel gears 310 are located in the inner cavity of the upper mounting groove 309.

[0059] A movable rod 311 is provided on the side wall of each connection between the fixing frame 203 and the fixing platform 202 on the upper and lower layers, and is rotatably provided through a bearing. The length direction of the movable rod 311 is consistent with the radius direction of the fixing platform 202. One end of the movable rod 311 is located in the inner cavity of the mounting groove 309 and is fixedly provided with a second bevel gear 312 that meshes with the first bevel gear 310.

[0060] The other end of the movable rod 311 is fixedly provided with a movable member 313. The movable member 313 is located inside the fixed frame 203 and always maintains a distance from the inner wall of the fixed frame 203. The cross-section of the movable member 313 in the top view direction is in the shape of "乁", and a movable frame 314 is rotatably arranged on the side of the movable member 313 away from the movable rod 311 through a bearing. The cross-section of the movable frame 314 in the front view direction is in the shape of an inverted "Y", and the inner side of the movable frame 314 is rotatably connected to the outer side of the sleeve 205 through a rotating shaft 315; the first bevel gear 310 at the lower end of the follower rod 306 is vertically meshed with the second bevel gear 312 of the movable rod 311, converting the vertical rotation of the follower rod 306 into the horizontal rotation of the movable rod 311. The movable member 313 at the outer end of the movable rod 311 is in the shape of "乁", and its end is rotatably connected to the movable frame 314 through a bearing. The movable frame 314 is connected to the sleeve 205 through the rotating shaft 315. When the movable member 313 rotates around the axis of the movable rod 311, it drives the sleeve 205 to reciprocate up and down to control the blade 206 of the swing rod 204;

[0061] A vertical transmission rod 316 is rotatably penetrated through the bottom wall of the inner cavity of the upper installation groove 309 through a sealing bearing. The number of the transmission rods 316 is the same as that of the follower rods 306, and the transmission rods 316 are respectively located directly below the corresponding follower rods 306;

[0062] The upper end of each transmission rod 316 is fixedly provided with a third bevel gear 317. All the third bevel gears 317 are located in the inner cavity of the upper installation groove 309, and the third bevel gears 317 are always meshed with the second bevel gears 312 located in the upper installation groove 309 correspondingly; the third bevel gears 317 in the upper installation groove 309 are meshed with the second bevel gears 312 to transmit the power of the movable rod 311 to the transmission rod 316, making the rotation direction of the transmission rod 316 opposite to that of the movable rod 311;

[0063] The lower end of each transmission rod 316 is rotatably penetrated through the inner top wall of the lower installation groove 309 through a sealing bearing. The lower end of each transmission rod 316 is fixedly provided with a fourth bevel gear 318. All the fourth bevel gears 318 are located in the inner cavity of the lower installation groove 309, and the fourth bevel gears 318 are always meshed with the second bevel gears 312 located in the lower installation groove 309 correspondingly;

[0064] The rotation direction of the transmission rod 316 is opposite to that of the movable rod 311, which facilitates the opposite swing directions of the upper and lower blades 206. The fourth bevel gear 318 at the lower end of the transmission rod 316 is engaged with the second bevel gear 312 of the lower movable rod 311, and finally the upper and lower blades 206 are swung in opposite directions. The number of teeth of the bevel gear pair is matched to ensure that the swing frequency error of the upper and lower blades 206 is small, thereby achieving stable shear stress generated by the swing, which is conducive to the monodispersity control of the microsphere particle size; when the upper blade 206 swings upward, the lower blade 206 swings downward, forming a "push up and pull down" convection cycle, combined with its own rotation, such a reciprocating cycle improves the uniformity of material mixing;

[0065] Example 3. On the basis of Example 1, the upper and lower surfaces of the rotating table 302 protrude from the upper and lower surfaces of the opening 301 respectively, and the upper and lower edges of the rotating table 302 are protruding with circular convex plates 319, and the two circular convex plates 319 are respectively located on the inner and outer sides of the outer shell 100, and the two circular convex plates 319 are provided with an annular inner groove 320 on the facing side, and the two inner grooves 320 are surrounded by embedded rolling balls 321, and the upper and lower layers of the balls 321 are in contact with the top wall of the outer shell 100 and the top wall of the inner cavity respectively.

[0066] The outer diameter of the circular convex plate 319 at the top is smaller than the inner diameter of the fixed ring 307, and the outer side of the circular convex plate 319 is always spaced apart from the inner side of the fixed ring 307; the upper surface of the rotating table 302 is always spaced apart from the lower surface of the fixed inner tooth 308; since the main bearing points of the stirring and turning mechanism 200 and the driving mechanism 300 are on the rotating table 302, and the rotating table 302 is rotatably arranged on the inside through a sealed bearing, in order to reduce the pressure on the rotating table 302, circular convex plates 319 are protrudingly provided on the upper and lower edges of the rotating table 302. The circular convex plates 319 located on the upper layer bear most of the force, and combined with the ball bearings 321, the circular convex plates 319 roll on the top wall of the shell 100 through the ball bearings 321 to support the rotational movement, and the ball bearings 321 cooperate with the inner grooves 320 to reduce friction resistance, thereby ensuring smooth transmission;

[0067] A hollow storage shell 322 is fixedly provided on the top of the housing 100. The inner cavity of the storage shell 322 accommodates the sun gear 304, the planetary gears 305 and the fixing ring 307. The storage shell 322 protects the gear transmission mechanism and prevents debris from intruding and affecting the operation of the equipment.

[0068] A vertical servo motor 323 is fixedly installed on the top of the storage shell 322. The output shaft of the servo motor 323 rotates through the inner top wall of the storage shell 322 through a bearing. The output shaft of the servo motor 323 is fixedly connected to the top of the main rotating rod 201 through a coupling. The servo motor 323 drives the main rotating rod 201 to rotate, providing power for the entire machine.

[0069] In the specific use process, the material is injected into the inner cavity of the shell 100 through the injection pipe 102, and the screen 101 divides the inner cavity into upper and lower areas. The emulsified material is temporarily stored above the screen 101. After the servo motor 323 is started, the output shaft drives the main rotating rod 201 to rotate vertically through the coupling. The main rotating rod 201 synchronously drives the upper and lower fixed platforms 202 to rotate around the central axis of the shell 100. The fixed frame 203 outside the fixed platform 202 makes a circular motion with the fixed platform 202, and the blade 206 rotates accordingly. At the same time, the rotating platform 302 of the driving mechanism 300 is rotated through the fixed hole 303 rotates with the main rotating rod 201, and the sun gear 304 drives the planetary gear 305 to rotate in the fixed internal tooth 308. The follower rod 306 at the lower end of the planetary gear 305 engages with the second bevel gear 312 of the movable rod 311 through the first bevel gear 310, converting the vertical rotation motion into horizontal rotation of the movable rod 311. The movable part 313 pushes the movable frame 314 to swing around the rotating shaft 315, thereby driving the blades 206 to swing up and down while revolving and rotating. The upper and lower blades 206 are reversely driven by the transmission rod 316 to swing in opposite directions.

[0070] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
