Description

Technical Field

[0001] The utility model relates to the technical field of powder sampling, in particular to a powder transfer device with adjustable mass. Background Art

[0002] Dispersed solid phase extraction is widely used as a pretreatment method in the detection of pesticide residues and animal residues because it is fast, simple, cheap, effective, reliable, durable and safe. In the extraction and purification process, a certain amount of solid powder reagents are used as salting agents and purifiers. Although commercial products are available, the food sample matrix is complex and requires the use of purifiers that match the required powder filler type and filler amount.

[0003] At present, some laboratories still rely on constant weight balances to weigh extraction salting-out reagents and solid purifiers. The weighing time of a single solid powder is relatively long. Especially when a large number of repeated samplings of equal weight are involved, the weighing process is very time-consuming and it is difficult to meet the requirements of rapid batch transfer. Therefore, the utility model proposes an adjustable mass powder transfer device. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable mass powder transfer device, which has the advantages of simple structure, convenient use and adjustable mass, is suitable for the rapid transfer of a large amount of equal powder reagents, can improve the efficiency of powder reagent transfer, and solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable mass powder transfer device, comprising a sampling barrel and a base plate, the upper and lower ends of the sampling barrel are both open, the inner wall of the sampling barrel is provided with mass scale lines, the outer surface of the sampling barrel is provided with a mounting plate, the upper end of the mounting plate is rotatably mounted with a rotating shaft, the end of the rotating shaft is provided with a horizontal scraper, and a paddle plate is provided on the horizontal scraper, a mounting rod is installed at the center of the upper end surface of the base plate, a limiting plate is installed at the end of the mounting rod, the outer surface of the limiting plate is in contact with the inner wall of the sampling barrel, and an adjusting sleeve is installed at the upper end of the base plate, and the adjusting sleeve is located on the outside of the mounting rod and the limiting plate.

[0006] When using the utility model of an adjustable mass powder transfer device,

[0007] When sampling is required, the position of the limiting plate is adjusted according to the powder to be sampled. During adjustment, the adjusting sleeve is rotated to make the limiting plate rise or fall in the sampling barrel. The position of the limiting plate on the inner wall of the sampling barrel is observed at the mass scale line. The mass scale line indicates the weight of powder that can be loaded at different positions of the limiting plate in the sampling barrel. After adjustment, the sampling barrel is placed in the solid powder storage container by holding the handle to scoop up the solid powder. After the sampling barrel is filled with powder, the horizontal scraper is moved to scrape off the solid powder at the upper opening of the sampling barrel, thereby completing the sampling work.

[0008] Preferably, a handle is installed on the outer surface of the sampling cylinder, and the handle is located at the upper position of the outer surface of the sampling cylinder.

[0009] Preferably, an external thread is provided on the outer surface of the sampling cylinder, an internal thread is provided on the inner wall of the adjusting sleeve, the adjusting sleeve is installed on the outer surface of the sampling cylinder, and the adjusting sleeve is threadedly connected to the sampling cylinder.

[0010] Preferably, the horizontal scraping blade is horizontally arranged, and the lower end of the horizontal scraping blade contacts the upper end of the sampling cylinder.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: During sampling, the position of the material limiting plate is adjusted according to the weight of the powder to be sampled, so that the position from the upper end of the material limiting plate to the upper end opening of the sampling cylinder can exactly hold the required powder weight. For the sampling operation, the sampling cylinder is put into the solid powder storage by holding the handle to scoop up the solid powder. After the sampling cylinder is filled with powder, the horizontal scraping blade is toggled to scrape off the solid powder at the upper end of the sampling cylinder and the overflowed solid powder, thus completing the sampling work. There is no need to use a balance for weighing. For a large number of equal - amount samplings, only one adjustment is required, and then the sampling work can be repeated without readjusting the material limiting plate. The structure is simple, easy to use, and the quality is adjustable, which is suitable for the rapid transfer of a large number of equal - amount powder reagents and can improve the transfer efficiency of powder reagents.
