Vertical high-speed cement colloid mixer

Abstract

The invention discloses a vertical high-speed cement colloid mixer comprising an agitation vat and a mixing motor, wherein the mixing motor is a vertical mixing motor; the mixing motor is arranged above the agitation vat; a rotating shaft of the mixing motor is connected with the upper end of a vertical shaft at the center position inside the agitation vat; a first mixing impeller is arranged at the middle section of the vertical shaft; a second mixing impeller is arranged at the bottom of the vertical shaft; and the bottom of the vertical shaft is arranged at the center position of a discharge hole at the lower part of the agitation vat. The vertical mixing motor is adopted to output rotary power; the two mixing impellers in the vertical direction are driven at the same time; the time-sharing stirring process is finished; and the probability of blocking of cement colloid at the discharge hole of the agitation vat is obviously reduced, so that the mixer can stably and efficiently run for a long period of time; the pulping time is shortened; and the construction cost is saved. The mixer disclosed by the invention has the advantages of being low in mixing water cement ratio, high in production efficiency, simple in structure and low in failure rate.

Description

technical field [0001] The invention relates to a high-speed cement colloid mixer, in particular to a vertical high-speed cement colloid mixer with a low stirring water-cement ratio and less prone to blockage. Background technique [0002] The high-speed cement colloid mixer commonly used in China is mainly the vortex pulper. According to the pulping principle, this type of pulper uses the helical blade on the stirring shaft to make the vortex generate the lift of the upper and lower structures, so that the cement particles are fully uniform. To achieve the pulping effect. However, with the enhancement of modern construction strength and the increase of construction scope, the requirements for the water-cement ratio of slurry are also getting higher and higher, and the defects of this type of pulping machine are becoming more and more obvious. It is difficult to mix pure cement slurry or cement mortar with a high gray ratio (above 0.4:1), and the cement colloid is often blo...

AI Technical Summary

Problems solved by technology

However, with the enhancement of modern construction strength and the increase of construction scope, the requirements for the water-cement ratio of slurry are also getting higher and higher, and the defects of this type of pulping machine are becoming more and more obvious. It is difficult to mix pure cement slurry or cement mortar with a high gray ratio (above 0.4:1), and the cement colloid is often blocked at the outlet of the mixer. These problems seriously restrict the efficient construction of modern grouting

[0003] The reason for the above-mentioned problems in the above-mentioned traditional vortex pulper is that the vortex pulper is a horizontal pulper, and the horizontal stirring motor drives the stirring shaft to rotate, and drives the stirring impeller on the stirring shaft to rotate. Vertical structure, the outlet is set at the bottom of the mixing tank, so there is only one mixing impeller, which is set at the outlet of the mixing tank, and the pressure of the cement colloid above it is very high. If the cement colloid (pure cement slurry or cement mixed Mortar) with a low water-cement ratio (below 0.4:1), or the power of the mixing motor is insufficient, it is likely to be blocked, which will stop the mixer, delay the construction period, and increase the construction cost
