Description

Technical Field

[0001] This utility model relates to the technical field of nano-fragmentation devices, and in particular to an adjustable gap nano-fragmentation device. Background Technology

[0002] Currently, high-pressure homogenizing valves face multiple technical bottlenecks in practical applications, mainly manifested in core issues such as rapid wear of key components, sealing failure, insufficient thermal management, imbalance between energy consumption and efficiency, and limited material adaptability.

[0003] Under high-pressure conditions (100MPa), core components such as the valve core and valve seat are subjected to high-speed material impacts of 150-600m / s and cavitation effects over a long period, leading to accelerated metal fatigue and wear. For example, while a design with an excessively small gap between the homogenizing head and the valve seat (typically <0.1mm) improves shearing efficiency, it significantly shortens the lifespan of the components. Meanwhile, traditional sealing structures, such as the sealing surface, are prone to breakage under high-frequency vibration and thermal loads, and dynamic seals lack self-compensation mechanisms, often resulting in leakage and pressure loss.

[0004] In terms of thermal management, the instantaneous high temperature caused by cavitation is difficult to control effectively through passive heat dissipation. Existing heat dissipation jackets suffer from low heat exchange efficiency due to isolation from the homogenization chamber, affecting the stability of the physicochemical properties of materials. In addition, when increasing pressure to pursue higher homogenization, energy consumption increases exponentially. Every 10MPa increase in pressure leads to an approximately 15% increase in motor load. The volumetric efficiency of the three-plunger pump is limited by sealing performance and is difficult to exceed the theoretical upper limit of 75%. In terms of material adaptability, the fixed gap design is difficult to dynamically adjust, and it is prone to clogging when handling high-viscosity (>5000cP) or solid particulate materials. The homogenization effect fluctuates significantly with the characteristics of the material.

[0005] The existing technical solutions mentioned above have the following drawbacks: traditional designs rely too much on improving mechanical strength and neglect the material failure mechanism and energy transfer efficiency optimization under multi-physics coupling. Systemic breakthroughs are needed through structural innovation (such as adaptive gap adjustment), material upgrades (such as tungsten carbide coating), and thermo-mechanical coupling design. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable gap nanofragmentation device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An adjustable gap nano-fracture device includes a power mechanism, a valve body fixedly connected to one end of the power mechanism, a collision pin movably connected inside the valve body and the power mechanism, a buffer structure for buffering the collision pin inside the valve body, a collision head fixedly connected to the side of the valve body away from the power mechanism, and a fixed connector fixedly connected to the upper end of the collision head.

[0009] By adopting the above technical solution, a power mechanism is used to drive the striker to collide with the impact head, thereby generating an oscillating wave that is ejected from the fixed joint. During the collision, the buffer structure fully buffers the striker, reducing the instantaneous impact force on the striker, thus reducing the probability of striker damage and increasing the overall protection effect.

[0010] Furthermore, the power mechanism has an internal mounting groove for mounting the striker. A buffer spring is fixedly connected inside the mounting groove. A first abutting positioning block is movably connected to the side of the buffer spring away from the mounting groove. The inner side of the first abutting positioning block abuts against the outer side of the striker.

[0011] By adopting the above technical solution, the buffer spring can contract after receiving an impact, thereby ensuring that the first contact positioning block, the second contact positioning block and the movable steel ball produce a certain displacement, reducing the instantaneous impact force on the firing pin, increasing the overall impact protection effect, and thus increasing the service life of the firing pin.

[0012] Furthermore, an inner limiting block is fixedly connected to the upper end of the mounting groove. The inner limiting block has a horn-shaped structure with a diameter decreasing from top to bottom. A second abutting positioning block is detachably connected between the inner limiting block and the firing pin. The second abutting positioning block is located above the first abutting positioning block.

[0013] By adopting the above technical solution, the inner limiting block with a horn-shaped structure whose diameter gradually increases from top to bottom facilitates the downward movement of the first contact positioning block, the second contact positioning block, and the movable steel ball. Then, when there is no impact, the buffer spring pushes the first contact positioning block upward to facilitate the next impact.

[0014] Furthermore, the second abutment positioning block has a structure with an outward protrusion on the lower outer side, and the outer protrusion of the second abutment positioning block is adapted to the shape and size of the inner wall of the inner limiting block.

[0015] By adopting the above technical solution, the second contact positioning block with an outward protruding structure on the lower outer side can fit and contact the inner wall of the fixed inner limit block, increasing the force points of the firing pin and improving the overall installation effect.

[0016] Furthermore, a movable placement groove is reserved between the first and second abutment positioning blocks, and a movable steel ball is movably connected inside the movable placement groove.

[0017] By adopting the above technical solution, the movable steel ball can ensure that the first contact positioning block, the second contact positioning block and the firing pin can move easily, thereby ensuring that the firing pin is adequately buffered.

[0018] Furthermore, the movable steel balls are distributed in a ring at equal intervals inside the movable placement groove, and the contact surfaces of the first and second contact positioning blocks are adapted to the movable steel balls.

[0019] By adopting the above technical solution, the first contact positioning block, the second contact positioning block and the movable steel ball can move synchronously, ensuring a good overall buffering and protection effect.

[0020] In summary, the beneficial technical effects of this utility model are as follows:

[0021] 1. It adopts the steel ball locking principle. Through the geometric cooperation between the micro steel balls (0.5-1.5mm in diameter) distributed in the connector and the conical section of the ejector pin, a mechanical self-locking is formed when no external force is applied. It can withstand axial tensile force and ensure stability under high pressure conditions.

[0022] 2. When disassembly is required, a specialized tooling applies radial pressure to disengage the steel balls from the conical surface, enabling rapid and non-destructive assembly and disassembly of the ejector pin. This improves disassembly and assembly efficiency by over 80% compared to traditional threaded or crimped structures, making it particularly suitable for high-pressure homogenizing valves and other applications requiring frequent maintenance. In terms of dynamic performance, the spherical support structure at the ejector pin end allows for a ±2° swing margin. Combined with a 0.05-0.1mm floating gap between the steel balls and the conical surface, this effectively compensates for axial displacement caused by vibration or thermal deformation during equipment operation. Compared to traditional hard-connection methods, it reduces stress concentration by up to 60%. This multi-stage pressure-bearing system, through the distributed contact of the steel balls and the area multiplication effect of the ejector pin support end, controls local pressure within the material fatigue limit. While maintaining high-pressure operating pressure, it reduces the wear rate of critical contact surfaces to 1 / 3 of traditional structures.

[0023] 3. The modular steel ball locking mechanism and standardized interface design not only enable quick replacement of parts, but also adapt to the needs of different diameter (3-15mm) ejector pins, significantly expanding the material adaptability of the equipment. Compared with the pain points of disassembly damage and high maintenance costs that are common in current technologies, this structure, through the innovative integration of non-rigid connection and dynamic compensation mechanism, ensures high pressure sealing while taking into account ease of maintenance and reliability of long-term operation, providing a new technical path for the design of core components of equipment such as high pressure homogenizing valves.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 An adjustable gap nano-fracture device includes a power mechanism 1, a valve body 2 fixedly connected to one end of the power mechanism 1, a collision pin 3 movably connected to the valve body 2 and the power mechanism 1, a buffer structure 4 for buffering the collision pin 3 inside the valve body 2, a collision head 5 fixedly connected to the side of the valve body 2 away from the power mechanism 1, and a fixed connector 6 fixedly connected to the upper end of the collision head 5. The power mechanism 1 drives the collision pin 3 to collide with the collision head 5, thereby generating an oscillating wave, which is ejected from the fixed connector 6. During the collision, the buffer structure 4 fully buffers the collision pin 3, reducing the instantaneous impact force on the collision pin 3, thereby reducing the probability of damage to the collision pin 3.

[0030] Reference Figure 3 The power mechanism 1 has an installation groove 11 for mounting the striker 3. A buffer spring 12 is fixedly connected inside the installation groove 11. A first abutting positioning block 13 is movably connected to the side of the buffer spring 12 away from the installation groove 11. The inner side of the first abutting positioning block 13 abuts against the outer side of the striker 3. The first abutting positioning block 13, the second abutting positioning block 15, and the inner limiting block 14 all have smooth surfaces to facilitate overall buffering. An inner limiting block 14 is fixedly connected to the upper end of the installation groove 11. The inner limiting block 14 has a flared structure with a diameter that gradually increases from top to bottom. A second abutting positioning block 15 is detachably connected between the inner limiting block 14 and the striker 3. The second abutting positioning block 15 is located above the first abutting positioning block 13. The inner limiting block 14, with its flared structure with a diameter that gradually increases from top to bottom, ensures unidirectional movement of the whole.

[0031] Reference Figure 2The second abutment positioning block 15 has an outward protrusion on its lower outer side. The outer protrusion of the second abutment positioning block 15 is adapted to the shape and size of the inner wall of the inner limit block 14. The second abutment positioning block 15 with the outward protrusion on its lower outer side can abut against the inner limit block 14, increasing the overall abutment effect. A movable placement groove 16 is reserved between the first abutment positioning block 13 and the second abutment positioning block 15. A movable steel ball 17 is movably connected inside the movable placement groove 16. The movable steel ball 17 facilitates the movement of the first abutment positioning block 13, the second abutment positioning block 15 and the striker 3 when impacted. The movable steel balls 17 are distributed in a ring at equal intervals inside the movable placement groove 16. The contact surfaces of the first abutment positioning block 13, the second abutment positioning block 15 and the movable steel ball 17 are adapted to each other. The movable steel ball 17 ensures the movement of the first abutment positioning block 13, the second abutment positioning block 15 and the striker 3 under force, which facilitates the overall buffer protection.

[0032] The implementation principle of this embodiment is as follows: First, the power mechanism 1 drives the impact pin 3 to collide with the impact head 5, thereby generating an oscillating wave, which is ejected from the fixed joint 6. During the collision, the buffer structure 4 fully buffers the impact pin 3, reducing the instantaneous impact force on the impact pin 3. That is, when the impact pin 3 is impacted, the first contact positioning block 13 and the second contact positioning block 15 that the impact pin 3 contacts move into the mounting groove 11 along with the impact pin 3 until the impact pin 3 contacts the bottom of the mounting groove 11, reducing the instantaneous impact of the impact pin 3, thereby reducing the probability of damage to the impact pin 3. When the impact pin 3 separates from the impact head 5, the buffer spring 12 applies pressure to the first contact positioning block 13, so that the first contact positioning block 13, the second contact positioning block 15 and the inner limit block 14 contact and position, which facilitates the buffering of the next collision. In addition, during the overall buffering process, the movable steel ball 17 facilitates the movement of the first contact positioning block 13, the second contact positioning block 15 and the impact pin 3 when impacted, ensuring a good overall buffering effect.
