Bottom-mounted high-speed dispersing device for preparing silicon mortar for concrete

Abstract

The invention provides a bottom-mounted high-speed dispersing device for preparing silicon mortar for concrete. The bottom-mounted high-speed dispersing device has the following beneficial effects that after improvement, the bottom-mounted high-speed dispersing device comprises a dispersing barrel, a mortar discharging pipe, supporting legs, a variable-frequency dispersing motor, a powder feedingopening, a dispersing liquid feeding opening, a high-speed dispersing disc, a flow guide ring hinge plate and a barrel upper cover; wherein the top of the dispersing barrel is connected with the barrel upper cover, the variable-frequency dispersing motor is fixed below the dispersing barrel through a high-speed motor flange plate, the variable-frequency dispersing motor is connected with the high-speed dispersing disc through a corresponding high-speed bearing and a shaft, and the high-speed shaft and the dispersing disc extend into the dispersing barrel from the bottom of the dispersing barrel and are close to the bottom of the dispersing barrel; and a discharge port electromagnetic valve and a slurry discharge pipe are arranged at the bottom of the dispersion barrel. The high-speed dispersion device is relatively simple in structure, can realize high-speed dispersion of silicon mortar through reasonable mechanical structure and system integration, has relatively high dispersion efficiency, and is easy for inspection and maintenance of dispersion blades.

Description

technical field [0001] The invention relates to the field of concrete silica mortar preparation, in particular to a bottom-mounted high-speed dispersion device for preparing silica mortar for concrete. Background technique [0002] Silica fume is a large amount of highly volatile S produced in submerged heat electric furnaces during the smelting of ferrosilicon and industrial silicon (metal silicon). i o 2 and S i Gas, after the gas is discharged, it is rapidly oxidized and condensed with the air and precipitated. The average particle size of silica fume is 0.1-1μm, which is 1 / 50-1 / 100 of ordinary cement particles, and the specific surface area is 15000-25000m2 / kg. The main component is amorphous silica, which accounts for more than 85%. The chemical composition and particle size of silica fume determine that silica fume is a highly active pozzolanic admixture, which has a great influence on the macroscopic mechanical properties and durability of cement and concrete.

Problems solved by technology

However, there is currently no special high-speed pre-dispersion equipment and control system for silica fume slurry. Most of the dispersion of silica fume slurry is dispersed by conventional low-speed stirring. The dispersion effect of silica fume in the dispersion liquid is limited. The activity of silica fume and the role of improving workability
