[0030] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the following will be described with reference to the drawings.
[0031] INTRODUCTION
[0032] The specific embodiments provide an ultrahigh pressure microjet assembly, which belongs to the field of ultrahigh pressure microjet and can be applied in the fields of food, pharmaceuticals, cosmetics, biology and material science. The ultrahigh pressure microjet technology has great application potential in many fields due to its high efficiency, accuracy and wide applicability.
[0033] Further explanation: ultra-high pressure refers to the pressure level generated by it which is much higher than that of ordinary supercharging equipment, usually above 300 MPa, and the highest can reach 400 MPa, and it has the ability to continuously generate high pressure; in addition, micro-jet refers to the fluid sprayed out at a very high speed under the condition of ultra-high pressure (usually hundreds of megapascals) through a small nozzle, forming a high-speed and fine fluid jet, and the micro-jet is the core of the ultra-high pressure micro-jet technology, which realizes efficient and accurate material processing through high-speed and fine fluid jet, and has important application value in many fields.
[0034] Ultra-high pressure micro-jet technology is a physical treatment technology based on high-pressure fluid dynamics, mainly used for material micronization, homogenization and modification. This technology accelerates the fluid under ultra-high pressure and passes through micron-sized channels to generate strong shear force, impact force and cavitation effect, thereby realizing fine processing of materials. The core principle is to use a high-pressure pump to pressurize the fluid to tens or even hundreds of megapascals, and then form a high-speed jet through a micro-pore, so that the material experiences complex physical action in a very short time, achieving the effect of particle size reduction, uniform dispersion or structure modification.
[0035] In existing ultra-high pressure micro-jet equipment, due to the complex manufacturing process of core components such as high-pressure pumps, micro-pores and interactive cavities, the price of the entire equipment is high, so the cost of replacing the ultra-high pressure micro-jet equipment is also high. The ultra-high pressure micro-jet assembly provided in the specific embodiment adopts a modular design, which designs the equipment as a modular structure, facilitating maintenance and upgrading, and reducing long-term use costs. In addition, when the ultra-high pressure micro-jet technology has poor processing effect on some high-viscosity or high-concentration materials, it may cause blockage or reduce processing efficiency; in the ultra-high pressure micro-jet equipment provided in the specific embodiment, through the layout design of the micron-pore channel, the risk of blockage can be effectively reduced, thereby reducing the maintenance cost.
[0036] The high pressure and high speed jet of the existing ultra-high pressure micro-jet technology can cause wear of the equipment components (such as micron-pore channels and interactive cavities), increasing the maintenance frequency and cost.
[0037] Content
[0038] As shown in Figure 1 , the above-mentioned ultra-high pressure micro-jet assembly comprises:
[0039] A pressure booster 1, which converts low-pressure medium into high-pressure medium through the pushing force of the piston, that is, the piston is pushed to move by the hydraulic cylinder, and the piston pushes the material in the pressure booster 1 to change the material from low-pressure medium to high-pressure medium.

When the material is placed in the hopper, the material can flow from the hopper into the multi-way check valve 2, and the material flowing into the multi-way check valve 2 can enter the booster 1 to become a high-pressure medium by the piston.
[0041] Homogenizing valve 3, the input end of the homogenizing valve 3 is connected with the output end of the multi-way check valve 2, the homogenizing valve 3 is provided with a cutting gap, so that the material entering the homogenizing valve 3 from the multi-way check valve 2 is cut by the cutting gap, and the input end of the cutting gap is the input end of the homogenizing valve 3; further, the homogenizing valve 3 is provided with a cavity, the cutting gap is located at the input end of the cavity, that is, the output end of the cutting gap is connected with the input end of the cavity, so that the droplets in the homogenate output from the cutting gap are broken by high-speed impact with the cavity, and the cavity phenomenon generated at the same time breaks the droplets, and the output end of the cavity is the output end of the homogenizing valve 3; further, the homogenizing valve 3 is provided with a pressure transmitter 31, which monitors, controls and records the material during homogenization, thereby ensuring safe operation of the equipment and stable product quality.
[0042] Interactive cavity 4, the input end of the interactive cavity 4 is connected with the output end of the homogenizing valve 3, the interactive cavity 4 is provided with a plurality of micron channels for the material to pass through, so that the material forms high-speed microjet when passing through the interactive cavity 4, and the plurality of micron channels are arranged in a honeycomb structure;
[0043] Heat exchanger 5, the input end of the heat exchanger 5 is connected with the output end of the interactive cavity 4, the heat exchanger 5 is used to adjust the temperature of the material output by the interactive cavity 4, and the heat exchanger 5 is provided with a stainless steel honeycomb tube for the material to pass through, so that the material exchanges heat when contacting the stainless steel honeycomb tube.
[0044] The booster 1, the multi-way check valve 2, the hopper, the homogenizing valve 3, the interactive cavity 4 and the heat exchanger 5 are connected through the union joint, so that the booster 1, the multi-way check valve 2, the hopper, the homogenizing valve 3, the interactive cavity 4 and the heat exchanger 5 become independent modules.
[0045] The following is a working description of the ultrahigh pressure microjet assembly.
[0046] The pressure booster 1 is a device that converts low-pressure medium into high-pressure medium through hydraulic or pneumatic means, widely used in industrial cutting, hydraulic systems and other fields. Its core is mainly to push a small piston with a large piston, converting low-pressure medium (such as oil or water) into high-pressure medium. The core of the pressure booster 1 is the reciprocating motion of the piston, which ensures the continuous output of pressure.
[0047] The multi-way check valve 2 is a fluid control device mainly used to control the one-way flow of fluid, prevent backflow, and ensure the continuity of the production process. By calling the pressure output of the pressure booster 1, the one-way flow of fluid is controlled, so the multi-way check valve 2 can improve the stability and reliability of the system, and reduce system failures caused by fluid backflow or pressure fluctuations.
[0048] The homogenizing valve 3 solves the problem of fluid homogenization. Specifically, the homogenizing valve 3 uses shear, impact and cavitation under high pressure to refine large molecules and particles in the fluid into small molecules and particles, thereby achieving the effect of homogenization. That is, under the action of high pressure, the fluid passing through a narrow cutting gap generates a large velocity gradient, forming a shear force that breaks up the droplets. At the same time, the droplets in the fluid collide at high speed with the cavitation of the homogenizing valve 3, further breaking up the droplets. In addition, the cavitation phenomenon that occurs when the fluid passes through a narrow channel under high pressure also breaks up the droplets, ultimately achieving the purpose of homogenization.
[0049] When the material passes through the interactive cavity 4, it forms a high-speed microjet under the action of ultra-high pressure (up to 60,000 psi / 4,000 bar / 400 MPa) through a very small pore (i.e. micron pore). The speed can reach 500 m / s (more than the speed of sound 340 m / s). After being processed by severe shear, oscillation, collision, cavitation effect and counterjet, the material undergoes physical, chemical and structural changes, ultimately achieving a reduction in particle size and a narrow distribution, accompanied by homogenization effects such as increased stability, uniformity and transparency.
[0050] The heat exchanger 5 uses a stainless steel honeycomb tube design as the core heat exchange element. The honeycomb tube structure is made of high-purity 316L stainless steel and has excellent thermal conductivity and mechanical strength.
[0051] In addition, the high pressure and high-speed jet of the existing ultra-high pressure microjet technology can cause wear and tear of the equipment components (such as the micron pore and the interactive cavity 4), increasing the frequency of maintenance and cost. Therefore, the micron pore and the interactive cavity 4 of the ultra-high pressure microjet assembly described in the present embodiment can be made of high-wear-resistant materials (such as diamond or ceramic) to manufacture the vulnerable parts, thereby prolonging the service life.
