Abstract

The invention discloses an efficient and energy-saving concrete water reducing agent blending device which comprises a tank body, a grinding plate, a transmission shaft, a twisting piece, a deposition tank, a first shaft sleeve and a second shaft sleeve; the grinding plate is arranged in the upper end of the tank body, the deposition tank is arranged in the lower end of the tank body, and a motor is arranged on the lower surface of the tank body; the transmission shaft penetrating through the lower end of the tank body is arranged on the upper surface of the motor, the upper end of the transmission shaft penetrates through the grinding plate and is connected with a first limiting block, a stirring rod is welded to the outer wall of the first limiting block, the twisting piece is arranged on the surface of the transmission shaft, and first connecting rods and second connecting rods are arranged at the two ends of the transmission shaft; and mixing plates are embedded between the first connecting rods and the second connecting rods, and screens distributed in a circular array are embedded in the surface of the grinding plate. The stirring rod, the twisting piece and the material mixing plate are synchronously driven to rotate through the transmission shaft, so that fed raw materials can be synchronously ground, the blending uniformity can be improved, and the actual use effect is better.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to a high-efficiency and energy-saving concrete water reducing agent mixing device. 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. [0003] In the production process of concrete superplasticizer, since various raw materials need to be mixed, blending equipment is needed to uniformly mix the raw materials for subsequent processing. [0004] After a large number of searches, it was found that the prior art...

[0004] After a large number of searches, it was found that the prior art, the publication number is CN213198202U, discloses a high-strength energy-saving concrete water reducer mixing device, including a shell, the top of the left side of the shell is bolted with a receiving hopper, the receiving hopper The center of the bottom is connected with a feed pipe, the bottom end of the feed pipe communicates with the inner cavity of the housing, the top of the housing is bolted with a fixed frame, and the center of the top of the fixed frame is bolted with a protective Cover; the utility model can speed up the uniform mixing speed of the water reducing agent through the arrangement of the shell, the fixed frame, the motor, the driving gear, the stirring shaft, the driven gear and the stirring blade, so that the water reducing agent and the concrete are evenly mixed , which can improve the mixing efficiency of concrete, and solve the problem that the existing water reducer mixing device will cause eddy currents in the material during the mixing process, which will affect the mixing effect of concrete and water reducer, and the materials cannot be mixed evenly, thus The problem of reducing the efficiency of concrete mixing

[0005] To sum up, in the actual use of the existing concrete water reducing agent mixing equipment, the raw materials of the concrete water reducing agent will have a certain degree of agglomeration before being put into the mixing equipment, and the agglomerated raw materials will be agglomerated after being put into the mixing equipment The blending equipment cannot be crushed, which leads to some agglomerated raw materials after blending, which reduces the effect of blending and affects the subsequent processing. In order to solve the above problems, the raw materials need to be ground, so that It is necessary to add additional grinding equipment to crush the agglomerated raw materials, but it will increase the operating cost of the enterprise, the actual production is not efficient enough, and the existing stirring blending equipment will accumulate materials near the drive shaft during operation , that is, the fluidity of the material around the drive shaft is lower than that of the material far away from the drive shaft, which greatly reduces the mixing uniformity of the material
