Concrete water reducing agent preparation and processing system

Abstract

The invention relates to a concrete water reducing agent preparation and processing system. The concrete water reducing agent preparation and processing system comprises a base and a screening device,and the screening device is arranged on the upper surface of the base; and the screening device comprises a screening support, a screening unit, a screening branch rod, a pneumatic unit and a screening air cylinder. The following problems existing when a concrete water reducing agent is screened after being prepared and formed at present that when an existing water reducing agent screening deviceis used for screening smashed water reducing agent powder, the adopted screening action is single, only simple reciprocating type screening treatment is adopted, the powder is difficult to move alongwith the screening device all the time just like large particles, so that the powder is prone to accumulating on a screening mesh plate to cause mesh blockage, consequently, screening of the water reducing agent is not thorough enough, and the screening efficiency is low can be solved.

Description

technical field [0001] The invention relates to the technical field of concrete water reducer, in particular to a preparation and processing system of concrete water reducer. Background technique [0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete. Most of them belong to anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc., which can disperse cement particles after being added to concrete mixture, which can improve its workability, reduce unit water consumption, and improve concrete mixing. The fluidity of the compound; or reduce the amount of cement per unit to save cement. The present invention is aimed at a naphthalenesulfonate water-reducer. After the water-reducer is prepared, it needs to be pulverized. The particle size determines the effect after mixing with concrete. After the agent is crushed, it is sieved, so that the particle size of the sieved w...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the screening process after the preparation and molding of concrete water reducers: when the existing water reducer screening device sieves the pulverized water reducer powder, the sieving action is single, which is only simple. The reciprocating screening process, and the powder is difficult to move with the screening device like larger particles, so that the powder is easy to accumulate on the screening screen and cause mesh blockage, so the screening of the water reducer is not thorough enough. And the screening efficiency is low
