Double-runner-wheel pressure-regulating lifting type mixing mill

Abstract

The invention relates to the field of refractory dry material mulling equipment, and discloses a double-runner-wheel pressure-regulating lifting type mixing mill which comprises a support; a supporting column is arranged at the top of the support; a lower carrier plate is arranged at the top of the supporting column; a lower barrel is fixedly connected to the outer edge of the top of the lower carrier plate; an upper carrier plate is fixedly connected to the top of the lower barrel; and the top of the upper carrier plate is fixedly connected with an upper barrel. According to the double-runner-wheel pressure-regulating lifting type mixing mill, through the structural design that a rotary charging barrel disc rotates relative to runner wheels and scrapers, compared with the mode that an existing mixing mill controls runner wheels to rotate for rolling, the problems that the runner wheels are heavy and rotate around respective horizontal shafts under the action of a material friction force, when the edge runner mill works, large centrifugal force is generated, vibration is large, especially when the two runner wheels are unbalanced, the phenomenon is more serious, consequently driving energy consumption is high, and damage is prone to occurring are solved.

Description

technical field [0001] The invention relates to the field of refractory dry material mixing and kneading equipment, in particular to a double-roller pressure-regulating lifting type kneading machine. Background technique [0002] Double roller mixer is a kind of mixing equipment that can mix dry materials and semi-dry materials, and can develop high-quality refractory materials according to actual needs. It is widely used in metallurgy, chemical industry, medicine, machinery, light industry, etc. field, the existing double roller kneader controls the rotation of the two rollers to crush the dry material on the tray, and additionally sets the stirring rotor and scraper between the two rollers. When feeding, the agglomerated materials are broken up and crushed, and the compacted materials are scooped up and rolled by the rollers again. [0003] However, when the existing double roller kneader is working, because the rollers have a relatively large weight, and the rollers rota...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing double roller kneader is working, because the rollers have a relatively large weight, and the rollers rotate around their respective horizontal axes under the action of material friction, this kind of roller mill produces a lot of energy during work. Large centrifugal force and large vibration, especially when the two rollers are unbalanced, resulting in high driving energy consumption and easy damage, and the existing mixer is fixed by the position of the scraper, which makes cleaning easier Raw materials are easy to accumulate in one place, resulting in poor rolling effect and low efficiency of raw materials
