Mixing device for high-strength and energy-saving concrete water reducer

Abstract

The invention discloses a blending device of a high-strength and energy-saving concrete water reducing agent. The blending device comprises a concrete stirring device body. A concrete feeding hopper is arranged above one side wall of the concrete stirring device body. A concrete outlet is formed in the center position of the bottom of the concrete stirring device body. Rotating shafts are arrangedat the bottom of an inner cavity of the concrete stirring device body in the length direction at equal distance, and the rotating shafts are arranged in the width direction of the concrete stirring device body. Arc mixing plates are arranged on the side wall of each rotating shaft in the length direction at equal distance. The cross section of each arc mixing plate is in a hook shape. One end ofeach rotating shaft extends to the outer portion of the concrete stirring device body through a bearing. The blending device is novel in design, simple in structure and convenient and fast to use; thewater reducing agent and water are synchronously and uniformly sprayed to concrete, and the water reducing agent and the concrete can be fast blended uniformly; and the time of stirring and mixing isreduced, and electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a mixing device for a high-strength energy-saving 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 basically unchanged. Most of them are anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it can disperse the cement particles, improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement. Appearance forms are divided into water and powder. The solid content of water formulations generally has 20%, 40% (also known as mother liquor), 60%, and the solid content of powder formulations is generally 98%. According to the water reducing and strengthening ability of the water r...

Problems solved by technology

[0003] When the existing water reducer is added, it is basically directly added to the concrete from a fixed position. In this way, the content of the water reducer at the adding point is high, and the content in other places is low, resulting in the distribution of the water reducer. Inhomogeneous situation, which reduces the efficiency of concrete mixing, it takes a long time to mix the water reducing agent evenly, in this process, too much water is added, and the water consumption cannot be greatly reduced, the water reducing agent The utilization rate is reduced, and the maximum effect cannot be exerted. Therefore, we have designed a high-strength energy-saving concrete superplasticizer mixing device to solve the above problems.
