Description

Technical Field

[0001] This invention relates to the field of emulsification technology, and more particularly to an internal and external circulation emulsifier. Background Technology

[0002] An emulsifier is a device used to mix solids and liquids, or multiple immiscible solutions, to form an emulsion. The emulsification process involves breaking down a solid (or liquid) phase into tiny powders (or droplets) and uniformly dispersing them in another continuous liquid phase (usually an aqueous phase). Emulsifiers utilize high-speed rotating blades or blades and a specially designed emulsifying head to generate strong shear forces and eddies, dispersing the liquid phase into tiny droplets. The shear force achieves miniaturization and uniform dispersion by introducing two immiscible phases into the emulsifying head and rapidly dispersing, shearing, and folding them.

[0003] Existing emulsifiers mostly use a single blade or blade to generate shearing force to mix two or more solid-liquid mixtures. Relatively speaking, the blade or blade of an emulsifier usually only contacts the solid and liquid substances once during one rotation. This results in low shearing efficiency of the emulsifier within the same processing time. Therefore, it is particularly important to propose an emulsifier with high shearing efficiency. In view of this, we propose an internal and external circulation emulsifier. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention controls the rotation of the connecting component through a drive component to drive the primary emulsifying structure to perform basic primary shearing. Simultaneously, the rotation of the primary emulsifying structure, in conjunction with a differential transmission structure, performs secondary shearing in sync with the secondary emulsifying structure. During the primary emulsifying structure and shearing process, the rotational force creates vortices in the solid-liquid mixture within the emulsifying tank, forcing some of the solid-liquid mixture after shearing by the primary emulsifying structure to enter the secondary emulsifying structure for secondary shearing in conjunction with the differential transmission structure. By utilizing the above operations, a significantly higher shearing efficiency is achieved compared to traditional emulsifiers.

[0015] 2. This invention, through the setting of differential drive helical gear A, causes the moving emulsifying shearing cutter head A to rotate, simultaneously driving the shearing output helical gear to rotate. The rotation of the shearing output helical gear causes the differential drive helical gear A and clutch shaft A to rotate synchronously, thereby enabling the clutch shaft A to drive the combined gear and connecting frame to rotate. The rotation of the connecting frame ensures that the differential transmission structure and the secondary emulsification structure rotate in the same position, adjusting the position of the solid-liquid material flow input and output ends during the secondary shearing process. This further achieves homogenization of the solid-liquid material after the primary shearing and the unsheared material, reducing ineffective over-shearing.

[0016] 3. This invention, by setting different sizes and tooth pitches for the shearing output helical gear, differential helical gear A, slow-speed shearing head assembly, differential helical gear B, differential drive helical gear A, and differential drive helical gear B, creates a differential action between the gears. The power output of the shearing output helical gear causes the differential drive helical gear A to rotate at double speed, causing the slow-speed shearing head assembly to rotate at double speed synchronously. Utilizing the meshing arrangement between the slow-speed shearing head assembly and the differential helical gear B, a relative speed-increasing rotation is achieved, causing the differential helical gear A to rotate synchronously, thus accelerating the rotation of the differential drive helical gear B. Based on the aforementioned homogeneous revolution action and the limiting effect of the connecting frame, a speed difference is synchronously created between the clutch shaft B and the clutch shaft A. The difference in rotational speed causes clutch shaft B to rotate relative to clutch shaft A when clutch shaft A's speed is zero. Clutch shaft B forces the emulsifying shearing head D to reciprocate within the connected extrusion groove under the guidance of the drive protrusion and the linear guide of the guide protrusion and the linear groove. This causes the emulsifying shearing head D to reciprocate and move closer to the emulsifying shearing head C, resulting in the synchronous shrinking and expansion of the secondary shearing cavity formed between the inner walls of emulsifying shearing head D and emulsifying shearing head C. This creates a negative pressure suction and pressurized discharge effect on the solid-liquid mixture, as well as a secondary shearing action. On the basis of external circulation, internal circulation shearing work is carried out simultaneously to achieve a further homogenization auxiliary effect of internal and external circulation.

[0017] 4. By setting up the auxiliary connecting channel D, the present invention enables liquid to enter and exit through the auxiliary connecting channel D during the relative negative pressure suction operation, relative to the shear connecting channel C and the shear connecting channel D, thereby improving the flow rate of solid and liquid substances in the secondary shear chamber under high-speed reciprocating negative pressure and pressurization conditions.

[0018] 5. This invention, through the arrangement of the large and small heads of the unidirectional flap and the truncated cone-shaped unidirectional flow cavity, allows the external solid and liquid substances to flow under the guidance of the unidirectional flow cavity during the return stroke of the emulsifying shear head C. Under negative pressure, the small head of the unidirectional flap is forced to unfold due to the misaligned flow groove, making it relatively easy for the solid and liquid substances to flow into the secondary shear cavity. At the same time, during the return stroke of the emulsifying shear head D, the small head of the unidirectional flap is tightly closed by the negative pressure force, making it difficult for the solid and liquid substances to flow out of the unidirectional flap at the emulsifying shear head D. Through the above operation, during the stroke, the unidirectional flap of the emulsifying shear head C closes, and the emulsifying shear head D opens relatively easily, forming a unidirectional flow channel to facilitate external circulation.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: An internal and external circulation emulsifier, see [link to example]. Figures 1 to 11The system includes a frame 1, an emulsifying tank 2, a drive assembly 3, a connecting assembly 4, and an emulsifying shearing system 5. The emulsifying tank 2 is mounted on the frame 1. The drive assembly 3 is located on one side of the emulsifying tank 2 and extends into the tank. The motor in the drive assembly 3 is mounted on one side of the emulsifying tank 2 via a mounting bracket and connects two synchronous pulleys via a belt. A keyway connecting rod is mounted and connected to one of the synchronous pulleys using a bearing on the emulsifying tank 2. The keyway connecting rod is connected to the rotating part of the connecting assembly 4, thereby driving the emulsifying shearing system 5 to rotate. The connecting assembly 4 is located on the drive assembly 1. The output end of component 3; the emulsifying shearing system 5 is arranged at the end of the connecting component 4; wherein, the emulsifying shearing system 5 includes a primary emulsifying structure 6, a differential transmission structure 7, and a secondary emulsifying structure 8; the primary emulsifying structure 6 is arranged at the end of the connecting component 4; wherein, the internal gap of the primary emulsifying structure 6 forms a secondary emulsifying cavity; the differential transmission structure 7 is arranged in the secondary emulsifying cavity; the secondary emulsifying structure 8 is arranged at the output end of the differential transmission structure 7; wherein, the driving component 3, the primary emulsifying structure 6, the differential transmission structure 7, and the secondary emulsifying structure 8 of the connecting component 4 constitute a multi-stage emulsifying shearing structure. This invention uses a drive component 3 to control the connecting component 4 to rotate and drive the primary emulsifying structure 6 to perform basic primary shearing. Simultaneously, the rotation of the primary emulsifying structure 6, in conjunction with the differential transmission structure 7, performs secondary shearing in sync with the secondary emulsifying structure 8. During the primary emulsifying structure 6 and the shearing process, the rotational force creates a vortex in the solid-liquid mixture within the emulsifying tank 2, forcing some of the solid-liquid mixture after shearing by the primary emulsifying structure 6 to enter the secondary emulsifying structure 8 for secondary shearing in conjunction with the differential transmission structure 7. By utilizing the above operations, a significantly higher shearing efficiency is achieved compared to traditional emulsifiers.

[0037] Specifically, the connecting assembly 4 includes a fixed base 401, a drive shaft 402, fixed rods 403, and a stabilizing block 404. The fixed base 401 is arranged inside the emulsifying tank 2. The drive shaft 402 is arranged at the output end of the drive assembly 3 and connected to the fixed base 401. The drive shaft 402 is movably connected to the fixed base 401. The three fixed rods 403 are arranged on one side of the drive shaft 402 and connected to the fixed base 401. The stabilizing block 404 is movably arranged at the lower end of the drive shaft 402 and connected to the fixed rods 403. This invention uses the rigid connection between the three fixed rods 403 and the emulsifying shearing system 5 to fix the primary emulsifying structure 6 components, and uses the drive shaft 402 to connect the shearing components of the primary emulsifying structure 6, so that the shearing components of the primary emulsifying structure 6 cannot rotate synchronously, thus completing the basic shearing work required.

[0038] Furthermore, the primary emulsification structure 6 includes a fixed emulsification shearing cover A601, a movable emulsification shearing head A602, and a shearing output helical gear 603; the fixed emulsification shearing cover A601 is arranged at the end of the fixed rod 403; and a plurality of shearing connecting grooves A6011 are uniformly formed on the outer surface of the fixed emulsification shearing cover A601; and a plurality of auxiliary connecting grooves A6012 are formed at the upper and lower positions on the outer surface of the fixed emulsification shearing cover A601; the movable emulsification shearing head A602 is movably arranged and extends inside the fixed emulsification shearing cover A601; and a plurality of shearing connecting grooves B6021 are uniformly formed on the outer surface of the movable emulsification shearing head A602. Furthermore, the moving emulsifying shear head A602 has several auxiliary communication grooves B6022 on its outer surface at the top and bottom; the shearing output helical gear 603 is arranged inside the moving emulsifying shear head A602 and extends to the outside of the fixed emulsifying shear cover A601; wherein, the surface of the shearing output helical gear 603 has an auxiliary communication groove C6031 that communicates with the auxiliary communication grooves A6012 and B6022; and the high end of the shearing output helical gear 603 is provided with a drive connecting shaft 6032 that is fixedly connected to the moving emulsifying shear head A602; and the drive connecting shaft 6032 is connected and fixed to the drive shaft 402 through a coupling. This invention provides auxiliary connecting grooves A6012 and B6022 on the upper and lower outer edges of the fixed emulsifying shearing cover A601 and the moving emulsifying shearing head A602, so that during high-speed cutting, solid and liquid substances enter and flow out to the outside of the fixed emulsifying shearing cover A601 to form an external circulation operation, thereby maintaining the basic fluidity of solid and liquid substances during the first-stage shearing operation.

[0039] Furthermore, the differential transmission structure 7 includes a combination gear 701, a connecting frame 702, a clutch shaft A703, and a differential drive helical gear A704; the combination gear 701 is movably arranged in the secondary emulsification chamber; and the combination gear 701 is composed of a differential helical gear A7011, a synchronous shaft 7012, and a differential helical gear B7013; the connecting frame 702 is arranged in an L-shape on the synchronous shaft 7012; the clutch shaft A703 is movably arranged at the high end of the connecting frame 702 in an inclined shape; the differential drive helical gear A704 is arranged on the clutch shaft A703 relatively close to the end of the shear output helical gear 603; and the differential drive helical gear A704 is meshed with the shear output helical gear 603. This invention utilizes a differential drive helical gear A704 to cause the moving emulsifying shearing head A602 to rotate, simultaneously driving the shearing output helical gear 603 to rotate. The rotation of the shearing output helical gear 603 causes the differential drive helical gear A704 and the clutch shaft A703 to rotate synchronously, thereby enabling the clutch shaft A703 to drive the combined gear 701 and the connecting frame 702 to rotate. The rotation of the connecting frame 702 causes the differential transmission structure 7 and the secondary emulsification structure 8 to rotate in the same position, adjusting the input and output positions of the solid-liquid material flow during the secondary shearing process. This further achieves homogenization of the solid-liquid material after the primary shearing and the unsheared material, reducing ineffective over-shearing.

[0040] It is worth noting that a movable cavity is provided inside the clutch shaft A703 on the side relatively away from the differential drive helical gear A704; and a linear groove 7031 is provided on one side of the movable cavity; a slow-speed shearing head assembly 7035 is provided on the surface of the clutch shaft A703 at an angle relative to the lower part of the drive shaft 402; wherein, the slow-speed shearing head assembly 7035 includes a secondary drive gear 7032 and an emulsifying shearing head C7033; wherein, the secondary drive gear 7032 is hollow; and a number of shearing connecting grooves C7034 are provided on the outer edge surface of the emulsifying shearing head C7033.

[0041] It is worth noting that the secondary emulsification structure 8 includes a clutch shaft B801, a differential drive helical gear B802, and an emulsification shearing head D803; the clutch shaft B801 is movably arranged at the lower end of the connecting frame 702 in an inclined manner; wherein, the clutch shaft B801 has a squeezing groove at the end relatively close to the differential drive helical gear A704; and the squeezing groove is formed by two spiral guide traction grooves 8011 connected end to end; the differential drive helical gear B802 is arranged at the end of the clutch shaft B801 relatively close to the combined gear 701; the emulsification shearing head D803... A linear auxiliary sleeve 8031 ​​is fixedly installed inside the emulsifying shearing head D803, which is sleeved on the end of the clutch shaft B801. The linear auxiliary sleeve 8031 ​​is movably connected to the clutch shaft B801 and the clutch shaft A703. A driving protrusion 8032 is provided on the inner wall of the linear auxiliary sleeve 8031 ​​relative to the extrusion groove. A guide protrusion 8033 is provided on the outer wall of the linear auxiliary sleeve 8031 ​​relative to the linear groove 7031. A plurality of shearing connecting grooves D8034 are opened on the outer edge surface of the emulsifying shearing head D803. This invention employs different dimensions and tooth pitches for the shearing output helical gear 603, differential helical gear A7011, slow-speed shearing head assembly 7035, differential helical gear B7013, differential drive helical gear A704, and differential drive helical gear B802, resulting in a differential action between the gears. The power output from the shearing output helical gear 603 causes the differential drive helical gear A704 to rotate at double speed, which in turn causes the slow-speed shearing head assembly 7035 to rotate at double speed synchronously. Utilizing the meshing arrangement between the slow-speed shearing head assembly 7035 and the differential helical gear B7013, a relative speed-increasing rotation is achieved, causing the differential helical gear A7011 to rotate synchronously, thereby increasing the speed of the differential drive helical gear B802. Based on the aforementioned homogeneous revolution action and the limiting effect of the connecting frame 702, a rotational force is simultaneously generated between the clutch shaft B801 and the clutch shaft A703. The speed difference is utilized to cause the clutch shaft B801 to rotate when the clutch shaft A703 is at zero speed. The clutch shaft B801 forces the emulsifying shear head D803 to reciprocate within the connected extrusion groove under the positioning and guidance of the drive protrusion 8032 and the linear guidance of the guide protrusion 8033 and the linear groove 7031. This causes the emulsifying shear head D803 to reciprocate and move closer to the emulsifying shear head C7033, resulting in the synchronous shrinking and expansion of the secondary shearing cavity formed between the inner walls of the emulsifying shear head D803 and the emulsifying shear head C7033. This creates a negative pressure suction and pressurized discharge effect on the solid-liquid mixture, as well as a secondary shearing action. On the basis of the external circulation, the internal circulation shearing work is carried out simultaneously to achieve a further homogenization auxiliary effect of internal and external circulation.

[0042] It is worth noting that both the emulsifying shear head D803 and the emulsifying shear head C7033 have several auxiliary connecting grooves D arranged in an annular pattern at equal intervals on their opposing surfaces; wherein, a one-way flap 9 is fixed inside the auxiliary connecting groove D. This invention, through the setting of the auxiliary connecting grooves D, enables liquid to enter and exit through the auxiliary connecting grooves D during relative negative pressure suction operations, relative to the shear connecting grooves C7034 and D8034, thereby improving the flow rate of solid-liquid substances in the secondary shearing chamber under high-speed reciprocating negative pressure and pressurization conditions.

[0043] It is worth emphasizing that the small head of the unidirectional flap 9 has staggered flow grooves arranged in an annular pattern at equal intervals, and most of the gaps in the inner wall of the unidirectional flap 9 form a frustum-shaped unidirectional flow cavity; wherein, the unidirectional flap 9 located on the emulsifying shearing head D803 and the unidirectional flap 9 located on the emulsifying shearing head C7033 are in the same direction. This invention utilizes the combination of a large and small head of a one-way flap 9 and a frustum-shaped one-way flow cavity. During the return stroke of the emulsifying shearing head C7033, external solid and liquid substances are guided by the one-way flow cavity and, under negative pressure, the small head of the one-way flap 9 is forced to unfold due to the misaligned flow groove. This allows the solid and liquid substances to flow relatively easily into the secondary shearing cavity. Simultaneously, during the return stroke of the emulsifying shearing head D803, the small head of the one-way flap 9 is tightly closed under negative pressure, making it difficult for solid and liquid substances to flow out of the one-way flap 9 at the emulsifying shearing head D803. Through the above operations, during the stroke, the one-way flap 9 of the emulsifying shearing head C7033 closes, and the emulsifying shearing head D803 opens relatively easily, forming a one-way flow channel to facilitate external circulation.

[0044] Working Principle: First, the required emulsified solid-liquid material is transported to the emulsification tank 2 through a pipeline. Then, the drive assembly 3 drives the drive shaft 402 and the moving emulsification shear head A602 to rotate. The rotation of the moving emulsification shear head A602 relative to the fixed emulsification shear cover A601, combined with the alternating shearing connecting grooves A6011 and B6021, performs basic shearing work on the solid-liquid material. At this time, the rotation of the moving emulsification shear head A602 causes the solid-liquid material to generate eddies. Auxiliary connecting grooves A6012 and B6022 are set on the upper and lower outer edges of the fixed emulsification shear cover A601 and the moving emulsification shear head A602 to facilitate the entry and exit of the solid-liquid material into and out of the fixed emulsification shear cover during high-speed cutting. The external circulation motion of A601 drives the differential drive helical gear A704 to rotate, causing the moving emulsifying shear head A602 to rotate and simultaneously driving the shear output helical gear 603 to rotate. The shear output helical gear 603, differential helical gear A7011, slow shear head assembly 7035, differential helical gear B7013, differential drive helical gear A704, and differential drive helical gear B802 are configured with different dimensions and tooth pitches, creating a differential action between the gears. The power output of the shear output helical gear 603 causes the differential drive helical gear A704 to rotate at double speed, causing the slow shear head assembly 7035 to rotate at double speed synchronously. The slow shear head assembly 7035 and the differential helical gear B701... The meshing setting of 3 allows for relative speed-increasing rotation, causing the differential helical gear A7011 to rotate synchronously, thereby increasing the speed of the differential drive helical gear B802. Based on the homogeneous revolution motion and the limiting position of the connecting frame 702, a speed difference is created between the clutch shaft B801 and the clutch shaft A703. This speed difference causes the clutch shaft B801 to rotate relative to the clutch shaft A703 when its speed is zero. The clutch shaft B801 forces the emulsifying shearing head D803 to reciprocate within the connected extrusion groove under the positioning and guidance of the drive protrusion 8032 and the linear guidance of the guide protrusion 8033 and the linear groove 7031. This causes the emulsifying shearing head D803 to reciprocate relative to the emulsifying shearing head C703. 3. The reciprocating insertion and withdrawal motion causes the secondary shearing chamber formed between the inner walls of the emulsifying shearing head D803 and the emulsifying shearing head C7033 to simultaneously shrink and expand, creating a negative pressure suction and pressurized discharge effect on the solid-liquid mixture, as well as a secondary shearing action. During the stroke, the unidirectional flap 9 of the emulsifying shearing head C7033 closes, while the emulsifying shearing head D803 opens relatively easily, forming a relatively unidirectional flow channel. Internal circulation shearing is performed synchronously on the basis of external circulation to further homogenize and assist the internal and external circulation. The rotating operation of the connecting frame 702 causes the differential transmission structure 7 and the secondary emulsification structure 8 to rotate in the same position, adjusting the input and output positions of the solid-liquid substances during the secondary shearing process.This further achieves homogenization of the solid-liquid substances after primary shearing and the unsheared substances, reducing ineffective excessive shearing.
