Proportioning device and preparation method of polycarboxylate superplasticizer

Abstract

The invention relates to the field of polycarboxylate superplasticizer production, in particular to a proportioning device and a preparation method of a polycarboxylate superplasticizer. The proportioning device comprises a mixing barrel, a batching disc and a finished product part, the mixing barrel comprises a barrel cover and a barrel body, an annular plate, a leakage port and a stirring motorare arranged on the barrel cover, and the stirring motor is placed in the annular plate; an output shaft of the stirring motor extends downwards into the barrel body, the lower end of the output shaftis connected with a stirring net, the periphery of the annular plate is sleeved with the batching disc, material containing grids distributed circumferentially are arranged on the batching disc, andthe material mixing barrel and the finished product part are separated through a drawing partition plate; and the drawing partition plate extends into the finished product part through a finished product side opening located in the side face of the finished product part. The proportioning efficiency can be improved, proportioning mass floating is reduced, and the uniformity of the polycarboxylatesuperplasticizer is stabilized.

Description

technical field [0001] The invention relates to the field of polycarboxylate water reducer production, in particular to a proportioning device for polycarboxylate water reducer and a preparation method thereof. Background technique [0002] Water reducer refers to an admixture that can reduce the amount of mixing water and increase the strength of concrete under the condition of constant workability of concrete and constant amount of cement; or save the amount of cement under the condition of constant workability and strength. In the prior art, some specific water reducing agents are often required in the production of concrete. Before adding, solid powder or granular ingredients need to be dissolved in water to make a single solvent solution, so as to ensure the uniformity of mixing , but concrete production generally needs to add a variety of ingredients, so different ingredients need to be comprehensively proportioned when making a mixed solvent solution. At present, the...

AI Technical Summary

Problems solved by technology

At present, the domestic polycarboxylic acid production process has many shortcomings such as cumbersome production, unsafe, environmentally friendly, and not energy-saving. The comprehensive proportioning operation for making water reducers is often manually weighed first, and the required different components are weighed after weighing. The ingredients are moved to the mixer, poured into the mixer, and mixed with a certain amount of water for stirring at the same time. The operation process is cumbersome, and the proportioning effect is greatly affected by human factors, and the uniformity is poor; at the same time, the efficiency of this proportioning method is low
