The embodiment of the application provides an emulsifying machine head 30 which is used for a high-shear emulsifying machine. The emulsifying machine head 30 has at least one set of stators and rotors, wherein the set of stators and rotors close to the liquid inlet is a feeding stator and rotor 302, and the radial clearance A between the stator 301 and the rotor 302 of the feeding stator and rotor is variable and gradually reduced along the conveying direction of the materials, namely along the direction from the feeding end to the discharging end of the stirring shaft 10. Therefore, compared with the existing stator and rotor 302 with a constant radial clearance a, the radial clearance a of the emulsifying machine head 30 provided by the embodiment of the present application on the side close to the feeding end is larger, so that the originally input liquid phase and solid phase, such as dust, particles and the like with different thicknesses, can more smoothly enter the radial clearance a between the stator 301 and the rotor 302. While the radial play on the side close to the discharge end is substantially identical to the prior art. Thus, the entered raw materials are more smoothly subjected to the comprehensive actions of strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in narrow gaps of the stator 301 and the rotor 302, so that immiscible solid phase, liquid phase and gas phase are instantly, uniformly and finely dispersed and emulsified under the combined action of corresponding mature processes and the like.
The technical solution of the present application is further described below with reference to some preferred embodiments.
As shown in fig. 1, an emulsifying machine head 30 includes a feeding stator and a feeding rotor, the feeding stator and the feeding rotor are sleeved on a stirring shaft 10 of an emulsifying machine, the feeding stator and the feeding rotor include: the rotor 302 is sleeved on the stirring shaft 10. And the stator 301 and the rotor 302 are arranged in a dual-meshing manner, and a radial clearance A exists between the stator 301 and the rotor 302, and the radial clearance A is gradually reduced along the direction from the feeding end to the discharging end of the stirring shaft 10.
Specifically, the emulsifying machine head 30 is used for a high-shear emulsifying machine, is suitable for the field of biological medicine, and is mainly used for emulsifying and mixing liquid phase and solid phase (dust and small particles). The emulsifying machine head 30 can comprise a set of stator and rotor, only the set of stator and rotor 302 near the feeding end makes the front part of the radial clearance A near the side of the feeding end larger than the radial clearance A of the existing stator and rotor by the gradually reduced radial clearance A between the stator 301 and the rotor 302, and the rear part of the gradually reduced radial clearance A is basically equal to the radial clearance of the high-shear emulsifying machine used in the existing biomedical field. The solid phase which starts to enter more smoothly enters the radial clearance A between the stator and the rotor under the action of the axial stress of the emulsifying machine after starting.
When a plurality of sets of stators and rotors 302 exist, because the liquid phase and the solid phase input to the stators and rotors are subjected to primary treatment at this time, the liquid phase and the solid phase can smoothly enter between the radial clearances A of the stators and rotors 302 under the action of axial suction, and the radial clearances of the subsequent stators and rotors can be constant as those of the existing stators and rotors.
Specifically, the gradually decreasing radial clearance a may be that the diameter of the working surface of the rotor 302 is unchanged, and the diameter of any point on the working surface of the stator 301 is gradually decreased along the material conveying direction, or the diameter of the working surface of the stator 301 is unchanged, and the diameter of any point on the working surface of the rotor 302 is gradually increased along the material conveying direction, or the diameter of any point on the working surface of the stator 301 is gradually decreased along the material conveying direction, and the diameter of any point on the working surface of the rotor 302 is gradually increased along the material conveying direction.
It is easy to understand that the working surface diameter of one of the stator 301 or the rotor 302 is not changed, and when the other one is changed, the parts on the existing emulsifying machine can be selected for production, or the existing high-shear emulsifying machine can be used for improvement, so that the emulsifying machine is convenient to popularize and use, can be popularized rapidly, and saves the cost of manufacturers.
Therefore, in some embodiments, the outer sidewall of the rotor 302 is configured as a cylindrical surface, and the diameter of the inner sidewall of the stator 301 gradually decreases along the direction from the feeding end to the discharging end of the stirring shaft 10.
Or in some embodiments, the inner side wall of the stator 301 is configured as a cylindrical surface, and the diameter of the outer side wall of the rotor 302 becomes gradually larger along the direction from the feeding end to the discharging end of the stirring shaft 10.
It should be appreciated that the working surfaces of both the stator 301 and rotor 302 of prior art high shear emulsifying machines are cut with a plurality of teeth 3021. Specifically, a plurality of saw teeth 3021 are circumferentially formed on an end surface of the outer side wall of the rotor 302 close to the feeding end.
And a plurality of second saw teeth 3011 are circumferentially configured on an end face of an inner side wall of the stator 301 close to the feeding end.
A side wall of the second saw tooth 3011 facing the saw tooth 3021 may be formed with a groove, the shape of the groove is not limited, and the axis of the groove may be parallel or perpendicular to the axis of the stirring shaft 10, or may be a shaped groove such as a V-shape. The arrangement of the grooves causes more vigorous impingement mixing of the liquid and solid phases between the teeth 3021 and the second teeth 3011.
Specifically, in some embodiments, the outer side wall of all the saw teeth 3021 is located on a first cylindrical surface, and the axis of the first cylindrical surface is collinear with the axis of the stirring shaft 10. Of course, the axis of the first cylindrical surface may also be non-collinear with the axis of the stirring shaft 10, but also remain parallel in a plane.
At this time, as shown in fig. 2c or fig. 2d, the inner side walls of all the second saw teeth 3011 are located on a spherical surface or a conical surface, that is, the boundary contour line of the curved surface of one side wall of the second saw tooth 3011 facing the saw tooth 3021 may be a diagonal line segment or an arc line segment. The axis of the partial spherical surface is collinear with the axis of the stirring shaft 10 or parallel on the plane, and the spherical center of the spherical surface is deviated to the side of the discharging end. The cone is likewise arranged with its axis collinear with the axis of the mixer shaft 10 or parallel in the plane. The collinear or parallel axes enable the structure of the emulsifying machine to be more compact, and simultaneously, the conveying of solid and liquid phases in the emulsifying machine is not hindered.
As shown in fig. 2a or fig. 2b, in some embodiments, the inner side walls of the second saw teeth 3011 are located on a second cylindrical surface, and the axis of the second cylindrical surface is collinear with or parallel to the axis of the stirring shaft 10; and the outer side wall of all the saw teeth 3021 is located on a spherical surface or a conical surface. The axis of the partial spherical surface is collinear with the axis of the stirring shaft 10 or parallel on the plane, and the spherical center of the spherical surface is deviated to the side of the discharging end. The cone is likewise arranged with its axis collinear with the axis of the mixer shaft 10 or parallel in the plane. The collinear or parallel axes enable the structure of the emulsifying machine to be more compact, and simultaneously, the conveying of solid and liquid phases in the emulsifying machine is not hindered.
As shown in fig. 3, in some embodiments, the gaps B between adjacent saw teeth 3021 and/or adjacent second saw teeth 3011 gradually become narrower along the direction from the feeding end to the discharging end of the stirring shaft 10. That is, the expanded shape of the serrations 3021 may be rectangular, trapezoidal, or arcuate or other equivalent shapes. At this time, the gaps B between the saw teeth 3021 and/or the second saw teeth 3011 are narrowed in the material conveying direction. The gradually narrowed gap can act together with the gradually reduced radial gap, so that the granular materials with different original thicknesses can more smoothly enter the space between the stator and the rotor 302 for gradual crushing, dispersing and emulsifying, and the production efficiency is improved.
In some embodiments, in order to further make the raw granular material with different thicknesses enter the radial clearance a more smoothly, the rotor 302 has a protrusion 3022, the protrusion 3022 is configured and arranged on one side end surface of the rotor 302 close to the feeding end, the protrusion 3022 extends towards the feeding end along the axial direction of the stirring shaft 10, and the protrusion 3022 is configured as any one of a circular truncated cone or a circular cone or a spherical segment.
Specifically, the rotor 302 is configured as a disk, and a sleeve portion is configured at the axis position of the disk, and the rotor 302 is sleeved on the stirring shaft 10 through the sleeve portion. The projection 3022 is provided on the sleeve portion. Projection 3022 may be a separate component that is secured to the mixer shaft 10 by threads or splines or pins. Or the protrusion 3022 may be integrated with the rotor 302, the protrusion 3022 is now a sleeve portion of the rotor 302, and the protrusion 3022 is still fixed to the stirring shaft 10 by a thread, a spline or a pin.
When the emulsifying machine is started, the material entering from the feed end is impacted on the convex part 3022 by the action of axial suction force and then thrown out into the saw teeth 3021 and the radial clearance a along the tangential direction of the convex part 3022.
Further, in some embodiments, the projection 3022 has a dispensing level on which at least 3 dispensing troughs 3023 are constructed and arranged, the distribution troughs including a curved portion that curves in the direction of rotation of the agitator shaft 10. When the lug boss is a circular truncated cone, the material distributing surface is the side surface of the circular truncated cone or the circular cone. When the lug boss is in a spherical segment shape, the material distributing surface is a spherical surface.
At least 3 curved material distributing grooves 3023 are formed on the material distributing surface, and the material distributing grooves rotate in the same direction, and the rotating direction is consistent with the rotating direction of the stirring shaft 10. As shown in fig. 4, the distributing groove 3023 may be a curved narrow groove milled on the distributing surface. Or the dispensing trough 3023 may be a notched portion between convexly curved ribs on the dispensing surface, which ribs may be welded to the dispensing surface.
