Abstract

The invention relates to the technical field of materials, and particularly relates to a continuous mixing tracer agent addition method for testing uniformity. The tracer agent addition device comprises the continuous mixing machine, wherein a tracer agent addition port is arranged in the side wall of a feeding port of the mixing machine and is provided with an atomizing nozzle which is sequentially connected with an infusion pump and a stirring device through a pipeline, wherein a flowmeter and a pressure detecting element are aslo arranged on the pipeline, and a regulating valve is arranged on the atomizing nozzle. When mixing uniformity is determined, after the mixing machine normally works, a tracer agent solution with certain concentration is mixed in a stirring tank and then is added to the mixing machine at a certain flow speed through the atomizing nozzle according to the capacity of the mixing machine, a sample is drawn from a discharging hole of the mixing machine, and the mixing uniformity of the sample is determined according to a national standard GB / T5918-2008 feed-product mixing uniformity determination method. The tracer agent addition device solves the problem that the uniformity indicator of the continuous mixing machine in the prior art cannot be accurately and really detected.

Description

technical field [0001] The invention relates to the technical field of material mixing, in particular to a device and method for adding a tracer when testing the material uniformity of a continuous mixer. Background technique [0002] The mixer is the most important equipment in the feed production process, and its performance directly determines the quality of the feed and the breeding effect. Mixing uniformity is one of the key performance indicators to measure the mixer. There are many types of feed mixers on the market, but they are mainly concentrated in batch type and continuous type. According to the national standard "GB / T5918-2008 Determination of Mixing Uniformity of Feed Products", the measurement methods of mixing uniformity of feed products include chloride ion selective electrode method and methyl violet method. Among them, the chloride ion selective electrode method only stipulates the analysis method of the sample, and the methyl violet method stipulates the...
