Problems solved by technology

[0004] Since the purity and application performance of nanopowder are easily affected by factors such as manufacturing method and process during the manufacturing process, the powder will be tested by sampling before it is put into production, and the content of additives and finished products will be tested. However, if the nano-powder is stored in a storage environment with high air humidity, it will condense into agglomerates due to water vapor. Not only that, the particle size after granulation is also different, and the internal content is also very different, resulting in random sampling test results. The referenceability is also low. In the actual detection process, although the required amount of samples is small, it is also difficult to obtain samples with similar particle sizes.

Embodiment

[0038] Example: refer to Figure 1-10 , a sampling and testing device for controlling the uniform dispersion of nano powders, including a circular base 1, a motor 11 is installed in the middle of the inner side of the base 1 in this example, and the upper end of the base 1 is threadedly fitted with the shell 2 located on the upper part of the base 1 , and the housing 2 is provided with a rotatable friction device 21, the bottom of the friction device 21 is provided with two teeth slots, and the output end of the motor 11 is connected with a bayonet corresponding to the slots at the bottom of the friction device 21, during actual use The use of the motor 11 in this example is not limited, and other driving structures can also be used instead. The screening process in this example requires a lower rotational speed of 50-80 rpm, and the centrifugal force produced is not enough to throw the friction device 21. out.

Abstract

The invention relates to the technical field of powder mixing equipment, in particular to sampling detection equipment for controlling uniform dispersion of nano-powder, which comprises a base, a shell movably mounted at the upper part of the base and a screening cavity arranged in the shell, and the screening cavity is used for screening the powder by a certain mesh number. A certain amount of powder is put into the shell, the friction device rotates to drive the powder to rotate in the shell in a circulating and reciprocating mode, the protrusions arranged at the bottom of the friction device enable the powder to continuously rub and make contact with the arc-shaped blocks at the bottom of the shell, and therefore the condensed powder is continuously rubbed to be broken; powder meeting the mesh number requirement is filtered out from the filter screen, meanwhile, air is intermittently blown into the screening cavity through the air expansion pipe arranged above the friction cover to assist in dispersing the congealed powder, meanwhile, the powder attached to the outer wall of the shell can be scraped away, congelation is avoided, and the qualified sample screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of powder mixing, in particular to a sampling detection device for controlling the uniform dispersion of nanometer powder. Background technique [0002] Nano-food refers to the nano-scale food obtained by using food high-tech to process and transform food components at the nano-scale. By reprogramming the molecules and atoms of the food, some structures of the food will change, which can greatly improve the quality of food. Improve the absorption rate of certain ingredients, reduce the toxic and side effects of health food, speed up the transportation of nutrients in the body, improve the absorption and utilization of mineral elements by the human body, and extend the shelf life of food. [0003] The most common powder nano food processing method in nano food is the physical method, under the action of impact or friction, the particles are refined, and in the physical processing method, the ball milling meth...
