Problems solved by technology

Because the material is modified by filter cake, the water content is large, the modified additive consumes a lot and cannot be recycled; and the stirrer involved in the patented device cannot be in close contact with the inner wall of the reactor, due to the unique thixotropic thickening of nano-silica property, it will cause cake-shaped wall in the dead corner of stirring
Then there is uneven mixing of modified
It is neither economical nor environmentally friendly, and has obvious technical defects

Abstract

The invention discloses a nano silicon dioxide stirring modification method and a device thereof, which comprise a kettle body and an operation method thereof, and are characterized in that closed cones with conical structures are adopted at the two ends of the kettle body, wherein the inner wall of the kettle body is provided with flow guide baffles. The nano silicon dioxide stirring modification method and the device thereof have the beneficial effects that the kettle body has a double-cone structure, power for flowing all materials can be provided, a mixing process from centralization to decentralization and from decentralization to centralization can also be finished, eight oblique flow guide baffles are arranged in the kettle body, so that the material which flows in the kettle at a high speed flows in a given direction, and thus, the material can be uniformly mixed and fully reacted. The materials with high probability of being adhered to walls and forming stirring dead angles such as powder and filter cakes in the production field of the nano silicon dioxide can be equivalently effectively modified. The stirring mode is unique, complex stirring shape and high-speed operation are not required, the technical difficulty is low, the equipment machining cost and the operation cost are low, and large-scale industrialization is easy to realize.

Description

technical field [0001] The invention relates to a method for producing silicon dioxide, in particular to a nanometer silicon dioxide stirring modification method and a device thereof. Background technique [0002] Nano-silica is one of the extremely important high-tech ultra-fine inorganic new materials, because of its small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, electrical resistance And other aspects have specific performance, with its superior stability, reinforcement, thickening and thixotropy, unique characteristics in many disciplines and fields, has an irreplaceable role. Nano silica is commonly known as "ultrafine white carbon black", which is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, metal softness Polishing agent...
