Environmental protection and energy saving vortex pulverizer

Abstract

The invention discloses an environment-friendly and energy-saving eddy crusher. The environment-friendly and energy-saving eddy crusher comprises a grinding chamber surrounded with an outer cylinder body, a rotating body arranged in the grinding chamber, a motor which drives the rotating body to rotate, a plurality of inner grinding blocks, a plurality of outer grinding blocks, and an inner barrel body; the plurality of inner grinding blocks and outer grinding blocks are peripherally uniformly distributed on two axial sides of the rotating body; and the inner barrel body is arranged between the inner grinding blocks and the outer grinding blocks; one of the surfaces of the inner grinding blocks and the outer grinding blocks in the rotating direction is a positive pressing surface, and the other one of the surfaces is a negative pressing surface; the positive pressing surfaces of the inner grinding blocks and the outer grinding blocks are arranged in front, and the negative pressing surfaces are arranged at back, according to the rotating direction; a negative pressing plate is arranged on each of the negative pressing surfaces of the inner grinding blocks and the outer grinding blocks; and the surfaces of the negative pressing plates, relative to the negative pressing surfaces of the inner grinding blocks and the outer grinding blocks, are arranged at certain intervals with the negative pressing surfaces of the grinding blocks; a front density cover plate and a rear sealing cover plate are respectively arranged at the front end and rear end of the outer barrel body; discharging ports communicated with the grinding chamber are formed in the front density cover plate and the rear sealing cover plate; and feeding ports are formed in the grinding chamber. The environment-friendly and energy-saving eddy crusher has a good crushing effect, is low in energy consumption and applicable to a plurality of fields, and has few requirements on rotating speed.

AI Technical Summary

Problems solved by technology

There is also a fluidized bed jet mill of Beijing Sanhuan Powder High-tech Company of the Chinese Academy of Sciences, and the material fineness d50 can only reach 2-40 microns

In addition, according to "ultrafine crushing and grading technology" (China Light Industry Press, published in 2001) literature report: the jet mill has the following problems: 1, large energy consumption, low production efficiency

2. The output is less, generally no more than 100kg / h, most of which are less than 50kg / h

3. It is still difficult to prepare superfine powder

4. The structure of jet mill is complex and expensive

However, the double negative pressure worm gear needs a higher speed, so the requirements for the strength of the motor, blades, and impact tooth plate are very high, and the energy consumption is also high.

In addition, the structure of the double negative pressure worm gear is also relatively complicated.
