矩形养殖池刮板排污装置的设计优化与验证
The design optimization and validation of a mechanical scraper discharge system for rectangular aquaculture tanks
摘要
Abstract
This study addresses the challenge of efficiently removing bottom solid waste in intensive aquaculture tanks by focusing on rectangular aquaculture tanks.A two-dimensional transient model,coupling the standard k-ε turbulence model with the VOF free surface model,was developed to optimize a mechanical scraper discharge system.Using an L25(53)orthogonal design,the effects of scraper height(6-14 cm),tilt angle(-20°-+20°),and speed(0.05-0.09 m/s)on particle distribution and discharge efficiency were analyzed.The results showed that the tilt angle had the most significant impact,with the optimal parameters being 6 cm height,+10° tilt,and 0.05 m/s speed,achieving the highest efficiency and minimal residue.To validate the numerical model,45 single-factor tests were conducted on a physical platform using particle recovery to quantify removal efficiency.Results deviated by only 5％-10％from simulations,confirming model accuracy.The study supports the engineering optimization of mechanical scraper systems.关键词
