Description

Technical Field

[0001] This utility model relates to the technical field of silicone oil emulsification equipment, and in particular to a silicone oil-specific emulsification equipment. Background Technology

[0002] Silicone oil typically refers to linear polysiloxane products that remain liquid at room temperature. It is generally classified into two categories: methyl silicone oil and modified silicone oil. Silicone oil is commonly used in emulsion preparation processes in lubricants, cosmetics, and electronic materials. Silicone oil usually needs to be pre-mixed with emulsifiers and dispersed in an aqueous phase through mechanical shearing, high-pressure homogenization, or other methods to form a stable silicone oil emulsion. As shown in the reference case "Involving a silicone oil emulsification device" announcement number "CN216093410U", the arrangement of the right-leaning vent pipe, the left-leaning vent pipe and the connecting flange facilitates the discharge of airflow. At the same time, the two oppositely arranged pipes block the silicone oil and emulsifier in the airflow, preventing the airflow from carrying out the silicone oil and emulsifier during the discharge process. In traditional silicone oil emulsification processes, common emulsification equipment often operates in an open or non-closed continuous flow mode, making it difficult to monitor changes in emulsion particle size in real time. Especially in high-viscosity silicone oil systems, due to uneven emulsification or excessively large particle size, some unqualified emulsions often enter subsequent processes, affecting the performance of the product.

[0003] Therefore, a silicone oil-specific emulsification device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a silicone oil-specific emulsification device to solve the above-mentioned problems. In the traditional silicone oil emulsification process, common emulsification devices often operate in an open or non-closed continuous flow mode, making it difficult to monitor changes in emulsion particle size in real time. Especially in high-viscosity silicone oil systems, due to uneven emulsification or large particle size, some unqualified emulsions often enter subsequent processes, affecting the performance of the product.

[0008] Preferably, a transfer pump is fixedly installed on the surface of both the guide tube and the return tube, and the guide frame is set in the shape of a funnel. The transfer pumps are used to drive the emulsion to flow efficiently in the guide path and the return path, respectively, to avoid flow obstruction or poor return caused by high viscosity silicone oil.

[0009] Preferably, the shearing assembly includes two drive blocks disposed on the outside of the drive rod, and a plurality of shearing blades are fixedly installed on the outside of the drive blocks. The plurality of shearing blades are arranged around the outside of the drive blocks.

[0010] Preferably, a reciprocating screw is fixedly mounted on the surface of the drive rod, the reciprocating screw is located between two drive blocks, a fixing ring is sleeved on the outer side of the reciprocating screw, the fixing ring is fixedly connected to the inner wall of the emulsification tank, and a connecting sleeve is rotatably mounted on the adjacent side of each of the two drive blocks, the connecting sleeve is slidably connected to the reciprocating screw, the reciprocating screw, through the thread engagement with the connecting sleeve, enables the drive blocks to achieve synchronous up-and-down reciprocating motion during rotation, forming a composite shear disturbance, which significantly improves the emulsification uniformity.

[0011] Preferably, the fixed ring is located between the two connecting sleeves, and a telescopic sleeve is fixedly installed between the two connecting sleeves and the fixed ring.

[0012] The beneficial effects of this utility model are: 1. The detection reflux component is connected to the outlet of the emulsification tank.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In practical implementation: such as Figure 1-4 As shown, a silicone oil emulsification device includes: an emulsification tank 1, a motor 2 fixedly installed on the top of the emulsification tank 1, and a detection tank 21 on one side of the emulsification tank 1; an emulsification detection mechanism 3, which is located on one side of the emulsification tank 1 for detecting and refluxing the emulsion particle size; wherein, the emulsification detection mechanism 3 includes a drive rod 31 fixedly installed on one side of the motor 2, the drive rod 31 being located inside the emulsification tank 1, a detection refluxing component 32 on one side of the emulsification tank 1, and a shearing component 33 on the outside of the drive rod 31. The shearing component 33 on the outside of the drive rod 31 is used to realize rotational shearing and up-and-down reciprocating disturbance, thereby improving the emulsification uniformity of the silicone oil emulsion. The detection refluxing component 32 is connected to the outlet end of the emulsification tank 1, which can detect the particle size of the silicone oil emulsion after the initial emulsification treatment, and transfer the emulsion with the required particle size to the subsequent process according to the detection results, and refluxing the unqualified emulsion for re-emulsification, ensuring that the product particle size is controlled within the standard range; Existing emulsification equipment typically consists of an emulsification tank 1, a motor 2, a shearing mechanism, and pipelines. This invention, without altering the main structure of the original equipment, embeds the shearing component 33 into the outside of the drive rod 31 in an assembly form. At the same time, a new detection reflux component 32 is added as an independent module connected to the outlet path of the emulsification tank 1. Neither of these measures affects the tank sealing or material flow, thereby improving emulsification quality and ensuring that the emulsified particle size is within acceptable limits.

[0017] like Figure 2 , Figure 3 and Figure 4As shown, the detection reflux assembly 32 includes a guide pipe 321 fixedly installed on one side of the emulsification tank 1. The other end of the guide pipe 321 is fixedly connected to the detection tank 21. A reflux tank 325 is provided on one side of the detection tank 21. The reflux tank 325 and the detection tank 21 are fixedly connected by a connecting pipe 326. A separation plate 323 is fixedly installed inside the detection tank 21. Multiple separation holes are opened on the surface of the separation plate 323. After the emulsion in the emulsification tank 1 flows into the detection tank 21 through the guide pipe 321, when the silicone oil particle size in the emulsion is smaller than the allowable range of the separation holes, it can pass smoothly through the separation plate 323 and flow to the discharge channel. The larger droplets are intercepted by the separation plate 323 and enter the reflux tank 325 through the connecting pipe 326, and then return to the emulsification tank 1 for secondary emulsification treatment. The top of the separation plate 323 is set as an inclined surface. The separation plate 323 is located on one side of the connecting pipe 326. A guide frame 324 is fixedly installed inside the detection tank 21. The guide frame 324 is located in the area of ​​the qualified emulsion falling path and is used to collect qualified particle size emulsion that passes through the separation hole of the separation plate 323. It is used for the directional diversion and centralized output of qualified emulsion. Transfer pumps 327 are fixedly installed on the surfaces of the guide pipe 321 and the return pipe 322. The guide frame 324 is set as a funnel shape. The transfer pumps 327 are used to drive the emulsion to flow efficiently in the guide path and the return path, respectively, to avoid flow obstruction or poor return caused by high viscosity silicone oil.

[0018] like Figure 2 , Figure 3 and Figure 4As shown, the shearing assembly 33 includes two drive blocks 331 disposed outside the drive rod 31. Multiple shearing blades 336 are fixedly mounted on the outer side of the drive blocks 331, surrounding the outer side of the drive blocks 331. During use, the motor 2 drives the drive rod 31 to rotate, simultaneously driving the two drive blocks 331 to rotate synchronously, thereby causing the multiple shearing blades 336 to rotate at high speed, forming a strong shearing force field to fully emulsify the silicone oil. A reciprocating screw 332 is fixedly mounted on the surface of the drive rod 31, located between the two drive blocks 331. A fixing ring 334 is sleeved on the outer side of the reciprocating screw 332, and the fixing ring 334 is fixedly connected to the inner wall of the emulsification tank 1. The two drive blocks 331 are adjacent to each other... Each side is rotatably mounted with a connecting sleeve 333, which is slidably connected to a reciprocating screw 332. The reciprocating screw 332 is in the form of two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. By rotating the reciprocating screw 332, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. The two connecting sleeves 333 are slidably set on one side of the fixed ring 334. When the motor 2 drives the drive rod 31 to rotate, the reciprocating screw 332 rotates synchronously, driving the connecting sleeves 333 to move up and down along the axial direction, so that the two drive blocks 331 reciprocate during rotation, forming a composite disturbance zone, which effectively enhances the fluid disturbance intensity inside the emulsification tank 1 and improves the emulsification efficiency and uniformity of high viscosity silicone oil. The fixed ring 334 is located between the two connecting sleeves 333, and a telescopic sleeve 335 is fixedly installed between the two connecting sleeves 333 and the fixed ring 334. The reciprocating screw 332 is located inside the telescopic sleeve 335. During the rotation of the drive rod 31, the reciprocating screw 332 drives the connecting sleeve 333 to move up and down reciprocally. The telescopic sleeve 335 expands and contracts with the reciprocating motion of the connecting sleeve 333, forming a closed protective structure to isolate external liquids or impurities and prevent emulsions such as silicone oil from entering the screw drive area.

[0019] In use, the material is first pre-emulsified in the emulsification tank 1 by the shearing component 33. Multiple shearing blades 336 rotate at high speed to shear the material, while the reciprocating screw 332 drives the material to move up and down, improving the uniformity of the pre-emulsification. The emulsion is then transported to the detection tank 21 via the guide pipe 321. The detection tank 21 uses the separation plate 323 to screen the particle size of the emulsion. Emulsion with the required particle size is discharged through the guide frame 324, while emulsion with the unqualified particle size enters the return tank 325 through the connecting pipe 326 and flows back into the emulsification tank 1 for shearing again, forming an emulsification closed loop. The detection and return component 32 can continuously screen and circulate emulsion with larger particle size during equipment operation, ensuring that the particle size of the final product is stable within the target range, thereby improving the emulsification quality.

[0020] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
