3results about How to "Simple sampling" patented technology

This utility model relates to the technical field of stirring devices, and specifically discloses a polyvinyl chloride reaction stirring device, including a discharge pipe and a sampling mechanism including a connecting hole, a connecting pipe, a filter pipe, a filter plate, and a cover plate. Each fixing mechanism includes an insert plate, a groove, a threaded hole, and a screw. Rotating the screw moves it away from the insert plate, at which point the cover plate is pulled to disengage it from the filter pipe. The material flowing in the discharge pipe flows into the pipe formed by the connecting pipe and the filter pipe, and flows out from the opening of the filter pipe. During the material flow, the material comes into contact with the filter plate. If material accumulates on the filter plate, it directly reflects that the material is unqualified, making it easy to detect production problems in a timely manner. At the same time, the staff can test the material flowing out of the opening of the filter pipe. Therefore, it is not necessary to open the tank cover or disassemble the equipment during the sampling process, avoiding the introduction of impurities and ensuring the purity of the material. The sampling process is simple and improves work efficiency.

This utility model discloses a portable device for rapid detection of mastitis in dairy cows, comprising a main body and a storage box. A negative pressure tube is installed at one end of the main body, and a cover is fixedly supported at the top of the negative pressure tube by a stabilizing frame. The output end of the cover is connected to the negative pressure tube via a liquid extraction tube. A detection box is installed on the top of the main body, with one end connected to the negative pressure tube via a liquid inlet tube. A movable tray is installed on the inner side of the other end of the detection box. An odor sensor, a color sensor, and a vision sensor are arranged side-by-side on the top of the detection box, with their detection ends extending above the movable tray. This utility model, through the coordinated operation of multiple sensors, can more accurately identify various abnormal phenomena in milk caused by inflammation, such as clots, flocculent matter, blood streaks, and turbidity. Compared to single detection methods, this multi-dimensional detection approach greatly improves the accuracy and reliability of the detection.
