Description

Technical Field

[0001] This utility model relates to the field of high-pressure homogenizer technology, and in particular to an adjustable high-pressure homogenizer. Background Technology

[0002] In fields such as biopharmaceuticals, food processing, and nanomaterials, high-pressure homogenizers are core equipment for refining and homogenizing fluid materials, and their performance directly impacts product quality and production efficiency. For scenarios involving the processing of materials with varying particle sizes (such as cell disruption, emulsion preparation, and nanoparticle dispersion), the equipment requires frequent replacement of valve seat assemblies adapted to different particle size requirements to meet diverse production needs. Against this backdrop, developing an adjustable high-pressure homogenizer capable of rapid valve seat replacement and flexible adaptation to different processing parameters has become a key direction for improving the flexibility and efficiency of industrial production.

[0003] Traditional high-pressure homogenizers typically use bolted connections for their valve seat assemblies. Bolted connections use multiple bolts to fix the valve seat to the machine body, requiring tools for assembly and disassembly, making the process cumbersome and time-consuming. While snap-fit ​​connections simplify some operations, they often rely on a single locking mechanism for positioning, making them susceptible to loosening due to vibration under high pressure, affecting equipment stability. Furthermore, existing sealing structures often use single rubber rings or hard metal seals, whose sealing performance depends on component machining precision and assembly processes. Under high-pressure fluid impact, these seals are prone to failure, material leakage, and other problems, and replacement costs are high after seal components wear out.

[0004] Existing high-pressure homogenizers require multiple bolt tightening or complex alignment operations when replacing valve seats, resulting in a single valve seat replacement taking tens of minutes. This is especially problematic on production lines that frequently switch between different particle size processing requirements. Frequent downtime for component replacement not only significantly reduces production efficiency but also increases labor costs. Furthermore, the unreliability of a single fixed structure can lead to valve seat positioning deviations, affecting the consistency of homogenized particle size and failing to meet the demands of high-precision production scenarios. Therefore, achieving rapid disassembly and precise positioning of valve seats has become a core technological bottleneck restricting the adaptability of high-pressure homogenizers to diverse production needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable high-pressure homogenizer, which aims to improve the existing high-pressure homogenizers that require multiple bolt tightening or complex alignment operations when replacing valve seats, resulting in a single valve seat replacement taking up to tens of minutes. This is especially problematic on production lines that require frequent switching of different particle size processing requirements, as frequent shutdowns for component replacement not only significantly reduce production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable high-pressure homogenizer, comprising a valve seat, a fixed ring slidably connected to one end of the valve seat, a homogenizing mechanism provided on one side of the outer wall of the valve seat, a homogenizer housing provided on one side of the homogenizing mechanism, a rotating ring rotatably connected inside the fixed ring, a rotating disk fixedly connected to the inner wall of the rotating ring, a sliding shaft slidably connected inside the rotating disk, a snap-fit ​​assembly provided on the outer wall of the sliding shaft, an arc-shaped sliding groove opened inside the rotating disk, a sliding rod slidably connected inside the rotating ring, a spring sleeved on the outer wall of the sliding rod, a sliding ring slidably connected inside the fixed ring, and a pressure plate slidably connected inside the fixed ring;

[0007] The snap-fit ​​assembly includes a snap-fit ​​block, the outer wall of which is fixedly connected to the outer wall of the slide shaft, and the outer wall of which is slidably connected to the inside of the fixing ring and the valve seat. The inside of the valve seat is provided with a snap-fit ​​groove.

[0009] Furthermore, one end of the second spring is fixedly connected to the inside of the sealing plate, and the other end of the second spring is fixedly connected to the inside of the limiting ring.

[0010] Furthermore, the outer wall of the sliding shaft is slidably connected to the inside of the arc-shaped groove, which is used to drive the sliding shaft to move.

[0011] Furthermore, the outer wall of the slide rod is slidably connected to the inside of the fixed ring, and the slide rod is used to guide the spring.

[0012] Furthermore, the outer wall of the sliding ring is slidably connected to the inside of the rotating ring, and the sliding ring is used to limit the rotation of the rotating ring.

[0013] Furthermore, one end of the spring is fixedly connected to the inside of the rotating ring, and the other end of the spring is fixedly connected to a sliding ring.

[0014] Furthermore, the outer wall of the limiting block is slidably connected to the inside of the limiting ring, and the limiting block is used to limit the sealing plate.

[0015] This utility model has the following beneficial effects:

[0026] 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.

[0027] Reference Figure 1 - Figure 5 This utility model provides an embodiment of an adjustable high-pressure homogenizer, including a valve seat 1. Different valve seats 1 correspond to different particle size requirements. By changing the valve seat 1, diverse production needs can be met. A fixing ring 2 is slidably connected to one end of the valve seat 1, serving as the mounting base for the valve seat 1, providing accurate installation position and support, and ensuring the stability of the valve seat 1 during operation. A homogenizing mechanism 17 is provided on one side of the outer wall of the valve seat 1, and a homogenizer housing 18 is provided on one side of the homogenizing mechanism 17. A rotating ring 3 is rotatably connected inside the fixing ring 2. The rotating ring 3 drives the rotating disk 4 to rotate, thereby realizing the sliding of the locking block 6 and completing the fixing and releasing operation of the valve seat 1. The rotating disk 4 is fixedly connected to the inner wall of the rotating ring 3, which has four arc-shaped sliding grooves 7 inside. Through the rotation of the rotating disk 4, the rotational motion is converted into linear sliding of the sliding shaft 5 and the locking block 6 by the cooperation of the arc-shaped sliding grooves 7 and the sliding shaft 5, thereby realizing the fixing and releasing of the valve seat 1. The sliding shaft 5 is slidably connected inside the rotating disk 4. The outer wall of the sliding shaft 5 is provided with a locking component. The sliding shaft 5 connects the arc-shaped sliding grooves 7 of the rotating disk 4 and the locking block 6. When the rotating disk 4 rotates, the sliding shaft 5 slides in the arc-shaped sliding groove 7, causing the locking block 6 to slide inside the fixing ring 2 and the valve seat 1, thereby fixing and releasing the valve seat 1. The rotating disk 4 has an arc-shaped sliding groove 7 inside, and the rotating ring 3 has a sliding rod 8 slidably connected inside. After the valve seat 1 is fixed, the sliding rod 8 rises under the action of the spring 9, and its top end is embedded in the limiting groove on the inner wall of the fixing ring 2, restricting the movement of the rotating ring 3 and preventing the rotating ring 3 from rotating due to vibration or other reasons, thus ensuring the reliability of the valve seat 1 fixing. The outer wall of the sliding rod 8 is fitted with the spring 9, which, when the valve... After seat 1 is fixed, spring 9 pushes sliding ring 10 and slide rod 8 to rise, so that the top of slide rod 8 is embedded in fixed ring 2, which provides power and keeps slide rod 8 in a stable position, ensuring effective limiting of rotating ring 3. Sliding ring 10 is slidably connected inside fixed ring 2, and pressure plate 11 is slidably connected inside fixed ring 2. When disassembling valve seat 1, the operator presses pressure plate 11 to overcome the elastic force of spring 9, so that slide rod 8 returns to rotating ring 3, releasing the limiting of rotating ring 3, so that rotating ring 3 can be rotated in the opposite direction to disassemble valve seat 1.

[0028] The snap-fit ​​assembly includes a snap-fit ​​block 6. Driven by the slide shaft 5, the snap-fit ​​block 6 slides inside the fixed ring 2 and the valve seat 1. When the rotating disk 4 rotates 90°, the snap-fit ​​block 6 is embedded in the annular groove on the outer periphery of the valve seat 1, fixing the valve seat 1 to the fixed ring 2. The outer wall of the snap-fit ​​block 6 is fixedly connected to the outer wall of the slide shaft 5. The outer wall of the snap-fit ​​block 6 is slidably connected to the inside of the fixed ring 2 and the valve seat 1. The valve seat 1 has a groove inside. The outer wall of the slide shaft 5 is slidably connected to the inside of the arc-shaped slide groove 7. The arc-shaped slide groove 7 is used to drive the slide shaft 5 to move. The outer wall of the slide rod 8 is slidably connected to the inside of the fixed ring 2. The slide rod 8 is used to guide the spring 9. The outer wall of the sliding ring 10 is slidably connected to the inside of the rotating ring 3. The sliding ring 10 is used to limit the rotation ring 3. One end of the spring 9 is fixedly connected to the inside of the rotating ring 3, and the other end of the spring 9 is fixedly connected to the sliding ring 10.

[0029] Specifically, when replacing the valve seat assembly of the adjustable high-pressure homogenizer, first align the bottom guide post of the valve seat 1 with the center through hole of the fixing ring 2 and insert it until the flange of the valve seat 1 abuts against the top surface of the fixing ring 2. Then, rotate the rotating ring 3, causing the rotating disk 4 to rotate synchronously. The four arc-shaped sliding grooves 7, which are symmetrically distributed in a cross shape and have a central angle of 90°, cooperate with the sliding shaft 5. When the rotating disk 4 rotates clockwise, the sliding shaft 5 slides away from the center due to the thrust of the arc-shaped sliding grooves 7, causing the locking block 6 to embed into the valve seat 1. The outer annular groove allows the rotating disk 4 to rotate 90° to lock. When locked, the slide rod 8 falls under gravity. After the valve seat 1 is fixed, the spring 9 pushes the sliding ring 10 to rise, causing the top of the slide rod 8 to embed into the limiting groove on the inner wall of the fixing ring 2, thus restricting the rotation of the rotating ring 3. When disassembling, press the pressure plate 11 to make the slide rod 8 return to the rotating ring 3, and rotate the rotating ring 3 in the opposite direction to pull out the valve seat 1. This mechanism, through rotation locking and spring limiting, can complete the replacement of different valve seats 1 within 1 minute, improving production changeover efficiency.

[0030] Reference Figure 1 - Figure 6The fixed ring 2 is internally fixedly connected to a limiting ring 12. When the valve seat 1 is inserted into the fixed ring 2, the limiting ring 12 serves to axially position the valve seat 1, ensuring that the valve seat 1 is inserted into the correct position. A sealing plate 13 is slidably connected inside the limiting ring 12. When the valve seat 1 is inserted into the fixed ring 2, the sealing plate 13, under the pressure of the valve seat 1, is pressed tightly against the inner wall of the valve seat 1 by the elastic action of spring 15, forming a sealing structure to prevent material leakage under high pressure. The outer wall of the sealing plate 13 is slidably connected to the inside of the valve seat 1, and a sealing plate 13 is fixedly connected inside the sealing plate 13. The telescopic rod 14 has a spring 15 sleeved on its outer wall. When the valve seat 1 is inserted into the fixing ring 2, the spring 15 is compressed by the valve seat 1 and contracts, generating a reverse thrust that pushes the sealing plate 13 to press tightly against the inner wall of the valve seat 1. The outer wall of the sealing plate 13 is fixedly connected to a limit block 16. One end of the spring 15 is fixedly connected to the inside of the sealing plate 13, and the other end of the spring 15 is fixedly connected to the inside of the limit ring 12. The outer wall of the limit block 16 is slidably connected to the inside of the limit ring 12. The limit block 16 is used to limit the sealing plate 13.

[0031] Specifically, when the valve seat 1 is inserted into the fixing ring 2, its lower end annular limiting ring 12 first enters the sealing cavity and achieves axial positioning through clearance fit. As the valve seat 1 continues to advance, its internal stepped surface pushes the sealing plate 13 to move inward, forming an initial contact seal with the inner wall of the valve seat 1. At this time, the spring 15 is compressed and contracts, causing the sealing plate 13 to fit tightly against the inner wall of the valve seat 1, forming an elastic seal. To prevent the sealing plate 13 from shifting, the limiting block 16 on the inner wall of the fixing ring 2 is embedded in the limiting groove on the outer periphery of the sealing plate 13.

[0032] Working Principle: When the adjustable high-pressure homogenizer is needed, first align the bottom guide post of valve seat 1 with the center through hole of fixed ring 2, and smoothly insert it axially until the flange of valve seat 1 abuts against the top surface of fixed ring 2. At this time, rotating ring 3 applies torque through the anti-slip teeth on its outer circumference or the drive handle, causing rotating disk 4 connected to it to rotate synchronously. The four arc-shaped sliding grooves 7 inside rotating disk 4 are symmetrically distributed in a cross shape, forming a sliding pair with the cylindrical end of sliding shaft 5. When rotating disk 4 rotates clockwise, sliding shaft 5 is subjected to radial thrust from the inner wall of arc-shaped sliding groove 7, and slides away from the center along arc-shaped sliding groove 7. The locking block 6 fixed at the other end is then embedded into the annular groove on the outer circumference of valve seat 1. Through the mechanical limit of rotating disk 4 rotating 90°, locking block 6 is completely locked into the locking position between fixed ring 2 and valve seat 1, forming a four-point symmetrical mechanical locking structure, realizing the rapid fixing of valve seat 1. In the locked state Under the influence of gravity, the slide rod 8 falls to its initial position. After its bottom end passes through the radial through hole of the fixed ring 2, the top stepped surface contacts the lower end face of the sliding ring 10. When the valve seat 1 is completely fixed, the spring 9 pushes the sliding ring 10 to rise axially along the inner wall of the fixed ring 2, causing the top end of the slide rod 8 to be embedded in the limiting groove of the inner wall of the fixed ring 2, forming a circumferential limit on the rotating ring 3, preventing it from rotating and loosening due to vibration under high pressure. When disassembling, the pressure plate 11 presses down on the top end of the slide rod 8, causing it to overcome the elastic force of the spring 9 and return to the clearance hole inside the rotating ring 3, releasing the limit on the rotating ring 3. Then, the rotating ring 3 is rotated in the opposite direction to reset the slide shaft 5 along the arc-shaped slide groove 7. The locking block 6 disengages from the valve seat 1 slot, and the valve seat 1 can be pulled out vertically. This mechanism achieves rapid replacement of valve seats 1 with different particle size requirements through the double locking of 90° rotation and spring limit, significantly improving production changeover efficiency.

[0033] In addition, when the valve seat 1 is inserted into the fixing ring 2, it will continue until it touches the limiting ring 12. Moving the valve seat 1 will cause the sealing plate 13 to enter the interior of the valve seat 1. At the same time, the pressure applied by the valve seat 1 will cause the spring 15 to contract, pushing the sealing plate 13 to fit tightly against the valve seat 1. The limiting block 16 will prevent the sealing plate 13 from moving, thus achieving efficient sealing.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
