Transportable moisture limit test sample solid-liquid mixer

Abstract

The invention provides a transportable moisture limit test sample solid-liquid mixer, which comprises a base. The base is connected to a box body bracket, which is equipped with a driving device and a moisture adding device. The driving device drives rotation of a mixing barrel through a drive mechanism, and the moisture adding device is communicated with the inner cavity of the mixing barrel through a liquid pipe. Solid-liquid mixing pretreatment is carried out on a sample before transportable moisture limit test, the mixer can realize quantitative adding of water into the to-be-tested sample, complete solid-liquid mixing, and saturated sample preparation, and moisture is not lost in the mixing process, the moisture measurement is controllable, and also barrels of different volumes can replaced to realize mixing of samples with different capacities, thereby effectively improving the test precision and ensuring transportation safety.

Description

technical field [0001] The invention relates to a solid-liquid mixer for experimental samples, in particular to a solid-liquid mixer suitable for pre-processing samples for the test of the transportable moisture limit of easily fluidized solid bulk cargo. Background technique [0002] In waterway transportation, for bulk goods, especially powdered minerals, the moisture content has a great influence on the safety of transportation. For example, for most concentrate powders and coal powders such as iron concentrate powder, copper concentrate powder, nickel concentrate powder, etc., if the internal moisture content is too high, fluidization will occur. Therefore, this type of cargo Known as liquefied solid bulk cargo, if this type of cargo liquefies due to excessive moisture content, it will cause the danger of the overall movement of the cargo, and in severe cases may lead to the unfortunate result of final ship destruction and death. Therefore, before loading such bulk carg...

Problems solved by technology

[0003] At present, the methods used to test the transportable moisture limit (TML) of easily fluidized solid bulk cargoes include the flow plate method, the insertion method, the saturation method, etc.; but there is no solid-liquid mixing pretreatment of samples before the test. Relevant equipment is available for use. The existing method is that the laboratory testing personnel manually add water, that is, drop water into the sample to be tested, and then fully mix it with a hand or a stirring rod, and then pass the flow plate method, insertion method, saturation method, etc. Degree method and other tests

There are many problems that are difficult to determine in the manual operation of sample pretreatment, such as whether the amount of water added is accurate, whether the sample to be tested and the water are mixed uniformly and sufficiently; and the final deviation of the test results will bring potential risks to waterway transportation.
