Efficient mixing device for production of water reducing agent for constructional engineering

Abstract

The invention discloses an efficient mixing device for production of water reducing agent for constructional engineering. The efficient mixing device comprises a mixing cylinder and a water pump, a suction bin is fixedly connected to a bottom plate of the mixing cylinder, differential pressure cavities are formed in a left side plate and a right side plate of the mixing cylinder, the upper portions of the differential pressure cavities communicate with the upper portion of the mixing cylinder through liquid discharging pipes, and an inlet of a motor is connected with the suction bin. An outlet of the motor is connected with the lower portions of the differential pressure cavities through a liquid supply pipe. During use, slurry prepared by water reducing agent production is put into the mixing cylinder, then the water pump is started, the mixed slurry enters the suction bin through a suction hole, the slurry sequentially passes through the liquid supply pipe, the differential pressure cavities and the liquid discharging pipe through work of the water pump, and flows back into the mixing cylinder from the upper part of the mixing cylinder, so that the circular flow of the slurry is realized, the phenomenon that the slurry sinks to the bottom can be avoided, meanwhile, the flowing slurry can be better mixed, and the mixing effect is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a high-efficiency mixing device for producing water reducing agents for construction engineering. Background technique [0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of the concrete basically unchanged. Most of them belong to anionic surfactants, including lignosulfonate and naphthalenesulfonate formaldehyde polymers. Etc. After being added to the concrete mixture, it has a dispersing effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement. [0003] The appearance of water reducing agent is divided into water agent and powder. The solid content of water agent is generally 20%, 40% and 60%, and the solid content of powder is generally 98%. Because...

Problems solved by technology

[0004] The powder water reducer needs to be mixed with a fixed ratio of clear water to make a slurry before use. In the prior art, the preparation and production of the water reducer is generally carried out by the rotation of the stirring paddle, but in this process, It is very easy for the powder to sink or float, which makes the stirring efficiency low and the mixing effect is not ideal
