基于振动筛分技术的养殖场防疫检测设备研究OA

[Objectives]The efficiency and quality of collecting sample was improved to solve the prob-lems of low efficiency of collecting sample,high impurity of sample,and high risk of personnel exposure in tra-ditional and manual sampling during epidemic prevention and testing in farms.[Methods]The vibration screen-ing technology was introduce into the design of equipment for epidemic prevention and testing.The principle of its application was clarified.The overall structure of modulate and core components of the equipment was in-novated with designing automation and safety protection.The on-site testing and case analysis were conducted.[Results]Compared with traditional manual sampling,the time of sampling for a single batch of 100 samples us-ing this equipment was reduced from 120 min to 45 min,reducing the impurity of the samples to 3％to 5％,achieving zero exposure between personnel and feces,with a detection pass rate of 98％.The area infected with latent intestinal pathogen was successfully identified in the farm of 5 000 mutton sheep in stock,reducing eco-nomic losses by about 500 000 yuan.[Conclusions]The equipment designed can solve the drawbacks of manual sampling.Its application will be expanded after optimization to assist the construction of epidemic prevention system for animal husbandry.
