1、 Jet system: the core power of multidimensional cleaning
The spray system of the fully automatic bottle washing machine achieves 360 ° cleaning of vessels through high-pressure water flow and precise spraying. Its design core is reflected in the following three aspects:
Collaborative design of spray arm and nozzle
Adopting a double-layer rotating spray arm structure, the upper spray arm is responsible for rinsing the exterior of the vessel, while the lower spray arm penetrates deep into the interior of the vessel. The nozzle layout has been optimized through fluid dynamics. For example, the Italian Steelco model adopts a "honeycomb nozzle array", which increases the water flow coverage area by 40%. At the same time, it can adapt to different vessel requirements such as beakers (low-pressure wide area flushing) and pipettes (high-pressure directional spraying) through adjustable pressure of 0.3-1.0MPa.
Water flow pattern control technology
Through the design of the vortex chamber inside the nozzle, the water flow is transformed into a "solid cone spray", so that the diameter of the water droplets is controlled within the range of 0.5-2 mm. This form can ensure both impact force (solid core) and expand coverage range (conical diffusion). The measured cleaning efficiency of 2ml injection vials is 27% higher than that of traditional direct water flow.
Dynamic pressure regulation system
Integrate pressure sensors and variable frequency pumps to automatically adjust pressure based on the degree of vessel contamination. For example, when processing protein precipitation, the system will activate a 0.8MPa high-pressure mode combined with alkaline cleaning agent to achieve a removal rate of 98.7%; When cleaning the glass culture dish, switch to the 0.4MPa low-pressure mode to avoid damage to the vessel.
2、 Water cycle design: balancing resource optimization and pollution control
The water circulation system achieves water and energy conservation through multi-stage filtration and heat recovery, and its technological breakthroughs are as follows:
Four stage filtration regeneration system
The first stage coarse filter (aperture 1mm) intercepts large particle impurities, the second stage surface filter (50 μ m) removes suspended solids, the third stage precision filter (5 μ m) captures particles, and the fourth stage reverse osmosis membrane (0.0001 μ m) purifies water quality. According to data from Hangzhou Xipingzhe Laboratory, this system can reduce the water consumption for a single cleaning from 120L to 38L, while ensuring that the final effluent conductivity is ≤ 0.1 μ S/cm, meeting the requirements for HPLC vessel cleaning.
Thermal energy recovery module
The 80-90 ℃ waste heat generated during the drying stage is preheated into the water through a plate heat exchanger, increasing energy utilization by 31%. According to actual tests conducted by a pharmaceutical company, when combined with thermal energy recovery, the comprehensive energy consumption of the equipment is reduced by 28% compared to the previous generation product, and the annual electricity cost is saved by over 20000 yuan.
Diversion control technology
Dynamically allocate water flow according to the cleaning stage: in the pre washing stage, use 30% circulating water+70% fresh water to remove large particles; The main washing stage uses 50% circulating water+50% fresh water combined with chemical cleaning; During the rinsing stage, 100% fresh pure water is used to ensure no residue. Through this design, the Guangzhou AiDisheng machine reduces the consumption of chemical reagents by 45% and the amount of rinse water by 60%.
3、 System collaboration: dual guarantee of efficiency and compliance
The collaborative design of the spray system and water cycle is reflected in the following scenarios:
Application of Biosafety Laboratory
When dealing with vessels contaminated with highly pathogenic microorganisms, the system first starts a 93 ℃ high-temperature water circulation (combined with peracetic acid disinfectant) for main washing, followed by three rinses through independent pure water pipelines, and finally uses HEPA filtered hot air drying. The entire process complies with BSL-3 laboratory standards, ensuring a microbial residue level of<1 CFU/piece.
Semiconductor industry applications
For the cleaning needs of wafer carrier boxes, the system adopts ultra pure water (resistivity>18M Ω· cm) circulating spray, combined with 0.1MPa low voltage mode to avoid static electricity generation. By precise control of the spray system and water circulation, the particle contamination level is controlled at ≤ 0.1 μ m to meet the production requirements of 12 inch wafers.
4、 Technological Evolution Direction
The current research and development focus is on two aspects:
AI driven dynamic optimization
By using vibration sensors and current monitoring, the risk of spray arm wear can be alerted 72 hours in advance, and the water flow parameters can be adaptively adjusted. Actual testing shows that this technology can increase the cleaning qualification rate of complex vessels from 92% to over 97%.
water cycle
Combining membrane bioreactor (MBR) technology to achieve 100% recycling of cleaning water. Initial experimental data shows that this solution can reduce wastewater discharge by 95%, but it needs to address the issues of membrane fouling and cost balance.
Core conclusion: The spray system and water circulation design of the fully automatic bottle washing machine achieve efficient resource utilization while ensuring cleaning quality through high-pressure precise spraying, multi-stage filtration regeneration, and heat recovery technology. Its technological evolution is shifting from single function optimization to intelligent and directional breakthroughs, becoming a fundamental equipment in the fields of precision manufacturing and scientific research experiments.
