AI Technical Summary

Technical Problem

In existing technologies, the detection process for available phosphorus and water-soluble phosphorus in phosphate fertilizer products is cumbersome, and the equipment is difficult to connect efficiently, resulting in low detection efficiency and low accuracy. In addition, it requires manual operation, which affects the quality control of phosphate fertilizer products.

Method used

A testing device was designed, comprising an ultrasonic machine, a test solution receiving component, a reagent box, an electric furnace, and a drying oven. The extraction, heating, filtration, and drying operations are automated through a feeding trolley and a tilting component. All components are closely integrated to achieve fully automated measurement throughout the entire process.

Benefits of technology

It enables efficient and automated detection of available phosphorus and water-soluble phosphorus in phosphate fertilizer products, shortens the testing time, improves the detection accuracy and pass rate, and meets the testing and control requirements of the production process.

Abstract

The present application belongs to the technical field of detection of phosphorus ammonium products, and particularly relates to a device and method for detecting available phosphorus and water-soluble phosphorus in phosphorus ammonium products, comprising an operation table; a first feeding trolley, a second feeding trolley and a third feeding trolley are sequentially and cooperatively arranged on the operation table; a first volumetric flask is hingedly connected to the bottom side of the first feeding trolley; a pouring assembly is arranged on the bottom side of the second feeding trolley, the pouring assembly comprising a beaker; a box cover cooperatively arranged with a drying box is arranged on the bottom side of the third feeding trolley, and a crucible filter is arranged on the bottom side of the box cover; when the third feeding trolley transports the crucible filter to the outside of the drying box and the third feeding trolley and the second feeding trolley are butted, the beaker and the crucible filter are close to each other, and the pouring assembly pours the mixture in the beaker into the crucible filter. Through efficient connection of the devices in each determination process, the overall determination process is more convenient, and the qualified rate and detection efficiency of phosphorus ammonium analysis and testing can be greatly improved.
