Description

Weighing device with packaging reagent

Technical Field

The utility model relates to the field of weighing equipment, in particular to a weighing device with a packaged reagent.

Background

In chemical production, most of the liquid raw materials are packed and stored in chemical standard containers such as industrial barrels, ton barrels and the like. When in use, the reagent in the chemical barrel needs to be poured out. For the amount of material, statistics on the amount are generally obtained by recording the amount used in the workshop. Although the volume of each barrel is standard, the accuracy of filling is generally not high, so that objective errors exist between the marked amount and the actual contained reagent amount. Meanwhile, in use, the standard capacity of each barrel is deviated from the actual consumption: the reagent is characterized by the fact that a small amount of residual and wall sticking situation is inevitably caused after pouring, so that the actual dosage is obviously lower, the dosage is judged through the barrel number when the reagent is fed each time, and accurate control and feedback of the material feeding amount are difficult to realize. For reactions with high demands and precision, the shop also needs to weigh before and after emptying, so that the exact amount of reagent used is obtained based on the difference.

At present, manual weighing is adopted in workshops, and the empty barrels are easy to weigh, but if the full barrels are weighed, the workload is large, the time spent for repeatedly carrying up and down the scales is long, and the shaking of the barrels by manual carrying is large, so that the shaking of the reagents in the workshops is obvious, and accurate data are difficult to obtain even if the reagent is put on a weighing platform. Resulting in difficult improvement of efficiency and data precision of the link and time and labor waste.

The steel cylinder weighing electronic scale (publication number: CN115979400A, main classification number: G01G 21/28) is specially used for weighing steel cylinders used in chemical industry, is mainly improved in corrosion resistance, and does not provide a solution for how to stabilize and efficiently transfer containers.
