Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a vacuum segmented high-speed shearing machine. Background Technology

[0002] A vacuum shearing machine is a mechanical device that uses a high-speed rotating rotor-stator structure to generate strong shearing force, impact force, and turbulence effect to refine and uniformly disperse particles, droplets, or agglomerates in a liquid. Its core objective is to achieve efficient mixing, emulsification, and homogenization of materials, and it is widely used in the food, pharmaceutical, cosmetic, and chemical industries. Existing shearing machines are typically suitable for large-volume industrial production, but they suffer from uneven mixing and emulsification. Therefore, sometimes it is necessary to recycle the raw materials for secondary or even multiple shearing operations. Their efficiency needs further optimization. Furthermore, when preparing highly unsaturated fatty acid-based compound emulsifiers, they cannot effectively and uniformly disperse the fatty acid-based materials into the continuous phase to form a stable system; at the same time, they cannot guarantee that the highly unsaturated fatty acid-based materials will not be oxidized. Utility Model Content

[0003] The main purpose of this invention is to provide a vacuum segmented high-speed shearing machine, which aims to improve the working efficiency of the shearing machine and optimize its mixing, emulsification and homogenization effects on raw materials, especially highly unsaturated fatty acid esters.

[0004] To achieve the above objectives, this utility model proposes a vacuum segmented high-speed shearing machine, comprising:

[0005] A workbench is provided with a liquid tank on one side of the workbench. The liquid tank has a liquid outlet channel at the bottom. A stirring structure is provided inside the liquid tank. A first driving component is connected to the bottom of the liquid tank. The stirring structure is driven to the first driving component.

[0006] The segmented shearing mechanism is disposed on the worktable surface adjacent to the liquid tank. The segmented shearing mechanism includes a guide shell, multiple shearing discs, and a second driving component. A shearing chamber is formed inside the guide shell and is connected to the liquid outlet channel. The shearing chamber has a discharge port at one end away from the liquid tank. The multiple shearing discs are arranged at intervals in the shearing chamber. A gap is left between the edge of the liquid disc and the inner wall of the shearing chamber. The multiple shearing discs are driven and connected to the second driving component.

[0007] In one embodiment of the present invention, the inner wall diameter of the shearing chamber gradually decreases in the direction away from the liquid tank, and the diameters of the plurality of shearing discs decrease accordingly one by one.

[0008] In one embodiment of the present invention, the second driving member is connected to a transmission roller extending into the shearing chamber, and a plurality of shearing discs are arranged at intervals on the surface of the transmission roller.

[0009] In one embodiment of the present invention, the shearing disc includes a base plate, a plurality of blades and a discharge ring. The base plate is inserted through the transmission roller. The plurality of blades are adjacent to the base plate and are evenly arranged circumferentially on the surface of the transmission roller. The discharge ring is vertically disposed on the edge of the base plate, and a plurality of discharge holes are formed on the surface of the discharge ring.

[0010] In one embodiment of this utility model, the liquid tank is divided into a tank body and a tank cover, and the tank cover has multiple channel openings.

[0011] This invention employs a segmented shearing mechanism with multiple shearing discs. Liquid enters the shearing chamber through the outlet channel and is mixed to the desired state under the action of the shearing discs. A gap is maintained between the shearing discs and the inner wall of the shearing chamber. As the shearing discs rotate, the mixed liquid continues to flow backward through the gap, where it is further dispersed and homogenized by the subsequent shearing discs. This multi-segmented shearing process ensures better mixing and homogenization of the liquid, eliminating the need for multiple shearing cycles and improving work efficiency.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Reference Figures 1 to 2 This utility model proposes a vacuum segmented high-speed shearing machine, including a worktable 1 and a segmented shearing mechanism. A liquid tank 2 is provided on one side of the worktable 1. The bottom of the liquid tank 2 has an outlet channel 3. A stirring structure 4 is provided inside the liquid tank 2. A first driving member 5 is connected to the bottom of the liquid tank 2. The stirring structure 4 is driven and connected to the first driving member 5. The segmented shearing mechanism is located on the surface of the worktable 1 adjacent to the liquid tank 2. The segmented shearing mechanism includes a guide shell 6, multiple shearing discs 7, and a second driving member 8. A shearing chamber 61 is formed inside the guide shell 6. The shearing chamber 61 is connected to the outlet channel 3. The shearing chamber 61 has an outlet 62 at the end away from the liquid tank 2. Multiple shearing discs 7 are arranged at intervals in the shearing chamber 61. A gap is left between the edge of the liquid disc and the inner wall of the shearing chamber 61. The multiple shearing discs 7 are driven and connected to the second driving member 8.

[0021] Understandably, the workbench 1 is the basic part of the shearing machine, and the segmented shearing mechanism is installed on the workbench 1. The workbench 1 provides support and operating space, while the segmented shearing mechanism is the core part that performs the shearing operation. The liquid tank 2 is located on one side of the workbench 1 and is used to store the liquid or material to be processed. There is a liquid outlet channel 3 at the bottom of the liquid tank 2, through which the liquid is sent out. The liquid tank 2 is equipped with a stirring structure 4, which is used to initially stir the liquid to ensure the uniformity of the liquid and to prevent material sedimentation or stratification. The bottom of the liquid tank 2 is connected to the first drive unit 5, which provides driving force for the stirring structure 4.

[0022] The segmented shearing mechanism is located on the surface of the workbench 1, close to the liquid tank 2. It mainly consists of the following parts: a guide shell 6, used to guide the liquid into the shearing chamber 61, which controls the flow of the liquid and allows it to smoothly enter the shearing area; multiple shearing discs 7, which are the key part of the segmented shearing mechanism, responsible for dispersing and mixing the liquid, and the multiple shearing discs 7 are arranged at intervals in the shearing chamber 61; and a second driving component 8, which is responsible for driving the rotation of the shearing discs 7, thereby realizing high-speed shearing of the liquid.

[0023] The shear chamber 61 is a space enclosed by the guide shell 6, used to contain liquid and perform homogenization mixing. The shear chamber 61 is connected to the liquid outlet channel 3, through which liquid enters the shear chamber 61 and is mixed to the desired state under the action of the shearing disc 7. At the end of the shear chamber 61 furthest from the liquid tank 2, there is a discharge port 62 through which the processed liquid is discharged. A gap is maintained between the shearing disc 7 and the inner wall of the shear chamber 61. When the shearing disc 7 rotates, the mixed liquid continues to flow backward through the gap and is further dispersed and homogenized by the subsequent shearing disc 7. This multi-stage shearing process ensures better homogenization of the liquid, eliminating the need for multiple shearing cycles and improving work efficiency.

[0024] In addition to the above structure, the shearing machine can also be equipped with vacuum pumps, pressure pumps, feed pipes, etc., depending on the working needs, which will not be described in detail here.

[0025] Reference Figures 1 to 2 In one embodiment of this application, the inner wall diameter of the shearing chamber 61 gradually decreases in the direction away from the liquid tank 2, and the diameters of the plurality of shearing discs 7 decrease accordingly one by one.

[0026] Understandably, the width of the shear chamber 61 gradually narrows from the end near the feed tank 2 to the end away from the feed tank 2. This structure allows the liquid to generate higher flow velocity and pressure during flow, thereby enhancing the shearing effect. Especially after the fluid enters the shear chamber 61, the shearing intensity of the fluid can be increased through this gradually narrowing space. Inside the shear chamber 61, the size of the multiple shearing discs 7 is designed to gradually decrease. From the end of the shear chamber 61 near the feed tank 2 to the end away from the feed tank 2, the diameter of the shearing discs 7 gradually decreases. This arrangement also helps the liquid to be subjected to increasingly stronger shearing action as it flows over each shearing disc 7. At the end near the feed tank 2, the shearing intensity is lower due to the larger shearing discs 7; while at the end away from the feed tank 2, the shearing discs 7 become smaller, and the shearing intensity increases, which is beneficial for fine processing of materials to achieve the required shearing effect.

[0027] Reference Figure 2 In one embodiment of this application, the second drive member 8 is connected to a drive roller 81 extending into the shearing chamber 61, and a plurality of shearing discs 7 are arranged at intervals on the surface of the drive roller 81.

[0028] Understandably, the second drive unit 8 is the core component used to drive the rotation of the shearing disc 7. It transmits power to the shearing disc 7 through a transmission roller 81, ensuring that the shearing disc 7 can effectively rotate at high speed, thereby achieving the shearing of materials. On the surface of the transmission roller 81, multiple shearing discs 7 are arranged at intervals, which helps the liquid to be gradually sheared as it passes through, avoiding obstruction of smooth flow due to overly dense shearing discs 7. The interval arrangement ensures that the material passes smoothly through each shearing disc 7, while allowing each shearing disc 7 to effectively perform shearing. Since the shearing disc 7 is driven by the transmission roller 81, this connection method ensures the synchronous movement and unified action of the shearing disc 7 throughout the shearing chamber 61, providing a consistent and efficient shearing effect.

[0029] Reference Figure 3 In one embodiment of this application, the shearing disc 7 includes a base plate 71, a plurality of blades 72 and a discharge ring 73. The base plate 71 is inserted through the transmission roller 81. The plurality of blades 72 are adjacent to the base plate 71 and are evenly arranged circumferentially on the surface of the transmission roller 81. The discharge ring 73 is vertically disposed on the edge of the base plate 71, and a plurality of discharge holes 74 are opened on the surface of the discharge ring 73.

[0030] Understandably, the base plate 71 is a relatively robust circular plate structure that provides basic support for the entire shearing disc 7. Multiple blades 72 are the core components of the shearing disc 7, responsible for the actual shearing and crushing of the material passing through the shearing chamber 61. The blades 72 are evenly distributed on the shearing disc 7 to ensure that the material is cut uniformly as it flows through. The discharge ring 73 is located at the edge of the shearing disc 7 and is used to control the discharge path and direction of the fluid. It helps guide the homogenized material away from the shearing disc 7.

[0031] The blades 72 are positioned close to the base plate 71 to ensure that the shearing function of the shearing disc 7 closely matches the base plate 71, improving the shearing effect. The blades 72 are evenly arranged around the base plate 71, ensuring consistency and efficiency in the shearing process and preventing over-shearing or under-shearing in certain areas. The discharge ring 73 is installed perpendicular to the edge of the base plate 71, and its surface has several discharge holes 74 for discharging the sheared material. This structural design facilitates smooth material discharge. When the material passes through the shearing disc 7, the material that has undergone shearing is guided by the discharge ring 73 and flows smoothly to the downstream area.

[0032] Reference Figures 1 to 2 In one embodiment of this application, the liquid tank 2 is divided into a tank body 21 and a tank cover 22, and the tank cover 22 is provided with a plurality of channel openings 23.

[0033] Understandably, tank body 21 is the main part of liquid tank 2, a container used to store liquid materials, with a large volume to store and process sufficient materials. Tank lid 22 is the upper covering part of liquid tank 2, serving to seal it. It not only protects the material inside the tank from leakage but also has other functions, such as controlling the inflow of materials and regulating air pressure. Channel openings 23 are multiple holes opened in the tank lid 22, allowing materials or gas to enter or exit from inside the tank body 21. The channel openings 23 have specific sizes and numbers according to usage requirements, ensuring smooth material entry and exit or gas flow.

[0034] This invention employs a segmented shearing mechanism with multiple shearing discs 7. Liquid enters the shearing chamber 61 through the outlet channel 3 and is mixed to the desired state under the action of the shearing discs 7. A gap is maintained between the shearing discs 7 and the inner wall of the shearing chamber 61. As the shearing discs 7 rotate, the mixed liquid continues to flow backward through the gap and is further dispersed and homogenized by the subsequent shearing discs 7. This multi-segmented shearing process achieves better mixing and homogenization of the liquid, eliminating the need for multiple shearing cycles and improving work efficiency.
