Inverted long-angle arc swirl anti-corrosion paddle and inverted long-angle arc swirl anti-corrosion stirring paddle

Abstract

The invention discloses an anti-corrosion impeller with an inverted long-angle arc swirl and an anti-corrosion stirring paddle with an inverted long-angle arc swirl. The technical point of the present invention is that the upper convex surface of the two sides of the arc-shaped blade is an inverted long angle, and together with the lower part of the two sides close to the right-angled side, the upper liquid entry surface and the lower opening liquid surface of the blade are formed, and the side of the upper liquid entry surface The sides are composed of two angled lines with similar lengths; the root of the convex surface of the arc-shaped blade is the part close to the stirring shaft, the middle part and the tail, that is, the cross-section of the part away from the stirring shaft is an arc surface formed by circles with different radii; the arc The cross-section of the root of the concave surface of the blade, that is, the part close to the stirring shaft, the middle part and the tail, that is, the part away from the stirring shaft is also an arc surface formed by circles with different radii. The invention provides an anti-corrosion paddle and a stirring paddle with an inverted long-angle arc swirl flow that can widen the extension force of the flow channel of the stirring paddle blade and the strong swirl force of several shapes, and has the effects of saving electricity, reducing consumption, increasing production, and has a long service life. .

Description

Technical field [0001] The invention belongs to the technical field of blades and stirring paddles, and particularly relates to a convex inverted long-angled arc-shaped swirling flow anticorrosive blade with strong invisible extending swirling force and an inverted long-angled arc-shaped swirling flow anticorrosive stirring paddle. The anti-corrosion stirring blade is a single-layer, four-bladed, double-layer, eight-bladed or a single-layer, three-bladed, double-layer, six-bladed, and is used for various anti-corrosion stirring in tanks and tanks equipped with mixing blades. Background technique [0002] Generally, in the electrochemical industry, due to the decrease in mineral resource content and the increase in leaching solid-to-liquid ratio, the process technology requirements of manganese dioxide, metal manganese, electrolytic copper and electrolytic aluminum are continuously improved, in order to adapt to its changeable advanced process technology , The technical requiremen...

AI Technical Summary

Problems solved by technology

The current design methods of agitating impellers are roughly divided into two categories: one is the traditional single-layer two or three impellers, double-layer two or three impellers and single-layer diversion agitating impellers, which generate small swirl force during operation , the multi-column force is not enough, the liquid mixing time is long, there is sediment at the bottom, and the stirring effect is poor

One is another patent of the applicant of the present invention "a large-scale anti-corrosion stirring paddle and its preparation method". Fluid principle distribution force technology, double-layer (bottom arc four paddles and upper straight board four paddles) eight paddles, three-layer (bottom straight board two paddles, middle arc four paddles, upper straight board four paddles) ten paddles, which belong to the system supporting multiple Several inventions, such as flow channel shape, paddle thickness, anti-corrosion strengthening of stirring shaft, integral seamless connection, mold design and preparation, several invention technologies and serial applications of active phenolic resin materials, the stirring effect is better than traditional 36 to 62 revolutions, double-layer eight paddles produce large swirl flow, multiple flow columns, extension force, invisible wave shape, strong force is not enough, applicable to various volume changes, there are limitations
