Description

Technical Field

[0001] This utility model belongs to the field of emulsification equipment technology, specifically relating to a high-efficiency homogenizing emulsifier. Background Technology

[0002] Homogenization and emulsification is a process that uses mechanical shear force to disperse immiscible liquids into fine-particle emulsions. It includes technologies such as ultrasonic emulsification, high-pressure emulsification, and microchannel emulsification, and is applied in the cosmetics, pharmaceutical, food, and chemical industries. This process operates in a vacuum environment, enabling aseptic production, improving emulsion stability, and eliminating air bubbles. The primary equipment for homogenization and emulsification is the homogenizer, which refines materials through high-speed rotation generating hydraulic shear and centrifugal extrusion effects. Homogenizers and emulsifiers are widely used in the cosmetics, food, and pharmaceutical industries to mix and emulsify multiple materials into a homogeneous system. Traditional homogenizers and emulsifiers often employ a single-layer shear structure, which suffers from uneven mixing and overheating, affecting emulsification efficiency and product stability. For example, some equipment may cause material denaturation due to temperature rise during high-speed rotation, or reduce emulsification efficiency due to a simplistic flow field design. Therefore, a system that optimizes the shear structure and temperature control is needed to improve emulsification quality and ease of operation. Utility Model Content

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0019] Example: As shown in the figure, the high-efficiency homogenizing emulsifier of this utility model includes a drive system 1 fixed on a frame 5. A drive motor 6 adjusts the output speed through a reducer and transmits the speed to a rotating shaft 7 via a coupling. The rotating shaft 7 passes through a top sealing cover and enters the emulsification chamber 2. The sealing cover uses a mechanical seal to prevent leakage. The multi-layer shearing discs 8 of the shearing mechanism 3 are installed at intervals with the stator ring 9. When the rotating shaft 7 rotates, the material is fed in through the feed inlet 10 and undergoes preliminary crushing and fine emulsification through the saw teeth and turbine structure of the multi-layer shearing discs 8. The through holes 17 and guide grooves 16 on the stator ring 9 guide the material to form a vortex, improving the mixing effect. The spiral flow channel 12 on the outside of the emulsification chamber 2 serves as a cooling system 4. Cooling water flows in from the inlet and out from the outlet, carrying away the heat generated during the process. The semi-circular cross-section of the spiral flow channel 12 increases the contact area, and the outer insulation layer 18 reduces energy loss. The emulsified material is discharged through the discharge port 11, and the valve control device 19 regulates the flow rate to achieve continuous or batch operation.

[0020] In this embodiment, the drive motor 6 adopts frequency conversion control, and the speed is adjustable from 0-3000 r / min to adapt to materials of different viscosities; the blade 13 of the multi-layer shearing disc 8 is made of stainless steel to ensure wear resistance and hygiene standards. This equipment was tested in the production of cosmetic emulsions, and the emulsion particle size distribution deviation was less than 5%, with temperature rise controlled within ±2℃, demonstrating its high efficiency and stability.

[0021] Working Principle: Based on the combined action of high-speed shearing and laminar flow mixing, when the drive system 1 is started, the drive motor 6 is adjusted to the preset speed through the reducer, and the power is transmitted to the rotating shaft 7 through the coupling, driving the multi-layer shearing disc 8 to rotate at high speed in the emulsification chamber 2. After the material enters the emulsification chamber 2 from the feed inlet 10, it is first subjected to the strong crushing action of the upper serrated cutter disc 13, which initially disperses the large particles. Subsequently, the material moves radially under the action of centrifugal force, passing through the narrow gap between the stator ring 9 and the rotor disc, where it undergoes an extremely high shearing rate, reaching tens of thousands of shearings per second. The lower turbine cutter disc 13 further accelerates the material and forms a high-speed jet through the through holes 17 on the stator ring 9, generating strong impact and vortex effects. At the same time, the inner wall guide groove 16 guides the material to form an axial circulating flow, which together with the radial shearing flow constitutes a three-dimensional composite flow field, ensuring that each material particle undergoes multiple shearing actions. This mechanical and hydraulic combined emulsification mechanism can break droplets down to the micron level, forming a stable and uniform emulsion system. Throughout the entire process, the cooling system 4 operates synchronously, with the cooling medium circulating within the spiral flow channel 12. It exchanges heat with the material through the wall of the emulsification chamber 2, precisely controlling the process temperature and preventing localized overheating from affecting product quality.

[0022] This invention utilizes a drive system connected to a rotating shaft via a coupling to drive the shaft to rotate at high speed. The shearing mechanism consists of multi-layer shearing discs on the rotating shaft and a stator ring on the inner wall of the emulsification chamber. The multi-layer shearing discs include a serrated upper cutter disc and a turbine-type lower cutter disc, which intersect with the stator ring to form a high-shear flow field. The emulsification chamber has an inlet at the top and an outlet at the bottom, with a spiral flow channel on the outer side serving as a cooling system. The spiral flow channel connects the inlet and outlet of the cooling medium to achieve real-time temperature control of the material. The cooperation between the multi-layer shearing discs and the stator ring enhances the radial and axial shearing forces, improving the emulsification uniformity. The spiral flow channel design of the cooling system optimizes heat exchange efficiency and prevents the material from overheating. The overall structure is compact and suitable for the continuous production of high-viscosity materials.
