High-purity silica powder dynamic immersion cleaning reaction kettle

Abstract

The invention discloses a high-purity silica powder dynamic immersion cleaning reaction kettle. The high-purity silica powder dynamic immersion cleaning reaction kettle comprises a tank body 2, a flange 3, a bearing pedestal assembly 4, a rotating shaft 5, a backrest connector 6 and a variable frequency motor 7, wherein the variable frequency motor 7 and the rotating shaft 5 are connected together through the backrest connector 6, the rotating shaft 5 is connected to the bearing pedestal assembly 4 and is in spline joint with the flange 3, the flange 3 is connected to the tank body 2 through a bolt, and the tank body 2 is in clearance fit and connected with a tank body cover 1. The high-purity silica powder dynamic immersion cleaning reaction kettle provided by the invention has the advantages that the electrodeless adjustment is realized by using the inherent variable frequency speed regulation and the stage speed regulation functions of a frequency converter, different rotating speeds are adopted in different reaction time periods, the full reaction and the energy conservation are realized, and the reaction time of materials is shortened.

Description

technical field [0001] The invention relates to the field of silicon production, in particular to a high-purity silicon micropowder dynamic soaking reaction kettle. Background technique [0002] At present, there are two types of high-purity silica powder leaching reaction devices: tank type and tank type, both of which are intermittent stirring leaching reactions at room temperature. During the process, the surface material on the upper part of the microsilica powder can be fully reacted, but the lower part cannot be fully reacted. The speed of the intermittent stirring reaction device cannot be adjusted, which consumes more energy. There is a phenomenon that the reaction is not complete when it is still. It takes 20 hours to react the material once. Due to the reaction at room temperature, the mobility of chemical liquid molecules is limited, and it often takes a long time to react the material once, and because of the stirring method, when the stirring rod is started inst...

[0002] At present, there are two types of high-purity silica powder leaching reaction devices: tank type and tank type, both of which are intermittent stirring leaching reactions at room temperature. During the process, the surface material on the upper part of the microsilica powder can be fully reacted, but the lower part cannot be fully reacted. The speed of the intermittent stirring reaction device cannot be adjusted, which consumes more energy. There is a phenomenon that the reaction is not complete when it is still. It takes 20 hours to react the material once. Due to the reaction at room temperature, the mobility of chemical liquid molecules is limited, and it often takes a long time to react the material once, and because of the stirring method, when the stirring rod is started instantly, the silicon micropowder has great resistance and friction to the stirring rod. , so that the protective material on the surface of the stirring rod will fall off every time, and the transmission device of the stirring rod will have mechanical powder and oil stains falling off, both of which will cause serious pollution to the silicon micropowder

When the material is cleaned, the material must be in a static state. Rinse it with a water pipe. Since the material is in a static state, the material deposits are very thick. No matter how to clean the ultrafine powder and impurities in the material, they cannot be completely cleaned. Since the washing depth and uniformity cannot be controlled manually, the loss of materials is also large. At the same time, because the water pipe is manually held and poured into the tank for cleaning, the lid cannot be closed, and the filling port is open for a long time. Cause certain external pollution and personal safety problems caused by operation
