Description

Technical Field

[0001] This utility model relates to the technical field of high-shear emulsifiers, specifically to a high-shear emulsifier for processing liquid defoamers. Background Technology

[0002] A high-shear emulsifier is a machine that can thoroughly refine and homogenize materials. It is widely used in the chemical, food, and pharmaceutical industries, primarily for uniformly mixing two or more immiscible liquids (such as oil and water) to form a stable emulsion. Its working principle is mainly based on high-speed shearing and stirring. The core components of a high-shear emulsifier are a high-speed rotating rotor (usually serrated) and a fixed stator. When the rotor rotates at high speed, the liquid is drawn into the narrow gap between the rotor and stator and torn into tiny droplets under the action of high-speed shearing force. This shearing force refines the liquid particles, thereby achieving uniform emulsification.

[0003] During high-speed rotation, wear is easily caused by frequent friction and shearing. This wear is particularly severe when handling high-viscosity liquids or liquids containing solid particles. Cleaning is especially difficult in the narrow gaps between the emulsifying heads, particularly after handling viscous or easily scaling liquids. Clogging may also occur when handling liquids containing solid particles or high viscosity. Utility Model Content

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: The stator and rotor of the shear emulsification process are improved to add replaceable assembly functionality. After wear, only the module needs to be replaced, eliminating the need for overall replacement, thus saving costs. The modular stator and rotor facilitate disassembly and cleaning, especially optimizing the structure of narrow gaps. Rapid disassembly and installation reduce downtime and improve efficiency. Simultaneously, it adapts to liquids with different viscosities and particle contents, allowing for stator and rotor replacement. Different modules adapt to different liquids, enhancing equipment versatility. It effectively optimizes problems such as mechanical wear, cleaning difficulties, and clogging, not only improving the practicality and economy of the equipment but also enhancing its adaptability and scalability. Furthermore, the addition of a sealing structure prevents foam and air from mixing in during shear emulsification, significantly improving the stability and uniformity of the emulsion.

[0016] Please see Figure 1-4 This utility model provides a high-shear emulsifier for processing liquid defoamers, including a storage tank 1. An outer plate 2 is fixedly connected to the bottom of the outer wall of the storage tank 1. A hydraulic cylinder 3 is symmetrically fixedly connected to the upper surface of the outer plate 2. A shearing emulsification structure 4 is fixedly connected to the other end of the hydraulic cylinder 3, and the bottom of the shearing emulsification structure 4 is placed in the inner cavity of the storage tank 1.

[0017] The shearing emulsification structure 4 includes a top plate 41. The lower surface of the top plate 41 is fixedly connected to the top end of the hydraulic cylinder 3. A bracket 48 is symmetrically fixedly connected to the lower surface of the top plate 41. An external threaded cylinder 43 is fixedly connected to the lower surface of the bracket 48. An internal threaded stator 44 is threadedly connected to the outer wall of the external threaded cylinder 43. The outer wall of the internal threaded stator 44 is uniformly provided with round holes. An annular cylinder 42 is fixedly connected to the center of the upper surface of the top plate 41. A servo motor 45 is set at the center of the annular cylinder 42. The lower surface of the servo motor 45 is connected to the flange at the center of the top plate 41. A motor shaft 46 is installed at the center of the lower surface of the servo motor 45. The side wall of the motor shaft 46 passes through the center of the top plate 41 and the bracket 48 in sequence. A sawtooth rotor 47 is set at the bottom end of the motor shaft 46. The center of the sawtooth rotor 47 is fixedly connected to the center of the motor shaft 46 by bolts. The side wall of the sawtooth rotor 47 is clearance-fitted with the inner wall of the internal threaded stator 44.

[0018] The upper surface of the storage tank 1 is uniformly provided with annular holes. The top cover 5 is attached to the corner of the upper surface of the storage tank 1 and is connected to the flange of the annular hole of the storage tank 1 by bolts. The center of the top cover 5 is fitted with the side wall of the shear emulsification structure 4 with clearance.

[0019] A rubber ring 6 is glued to the center of the upper surface of the top cover 5. The center of the rubber ring 6 is in clearance fit with the side wall of the shear emulsification structure 4, and the top of the rubber ring 6 is in contact with the shear emulsification structure 4.

[0020] Working Principle: During the shear emulsification of liquid defoamer, a suitable solvent or carrier, such as water or oil, is selected according to the formula, ensuring quality and freedom from impurities. Stabilizers or thickeners are added as needed. The storage tank 1 is then checked for cleanliness and residue before the solvent is poured into it. The top cover 5 is then fastened to the storage tank 1. Flange holes are provided at the contact points between the top cover 5 and the storage tank 1, and bolts are used for flange connection, providing initial shielding. The shear emulsification structure 4 is then lowered by the hydraulic cylinders 3 on both sides. The hydraulic cylinders 3 operate synchronously. During the raising and lowering of the shear emulsification structure 4, the top plate 41 of the shear emulsification structure 4 will adhere to the rubber ring 6 on the surface of the top cover 5. During high-speed stirring, the liquid easily generates foam and mixes in air. The top cover 5 and rubber ring 6 provide a seal during stirring, preventing foam and air from affecting the stability and uniformity of the emulsion. The servo motor 45 is guided to its center during installation by an annular cylinder 42. Bolts are provided on the surface of the top plate 41 to penetrate the servo motor 45, which is then secured with nuts, providing a replacement option for the servo motor 45. When installing the servo motor 45, the motor shaft 46 at the bottom of the servo motor 45 passes through the center of the top plate 41 and the bottom bracket 48. The sawtooth rotor 47 is then fixed to the motor shaft 46 with bolts. An external threaded cylinder 43 is also provided at the bottom of the bracket 48, and an internal threaded stator 44 is threadedly connected to it. During use, the servo motor 45 rotates, driving the sawtooth rotor 47. The core components of the shearing emulsification process are the high-speed rotating sawtooth rotor 47 and the fixed internal threaded stator 44. The outer wall of the internal threaded stator 44 has evenly distributed circular holes. When the sawtooth rotor 47 rotates at high speed, the liquid is drawn into the narrow gap between the sawtooth rotor 47 and the internally threaded stator 44, and is torn into tiny droplets under the action of high-speed shearing force. This shearing force can refine the liquid particles, thereby achieving uniform emulsification.
