Disaggregating equipment

Abstract

The invention discloses disaggregating equipment, which comprises a shell. An upper bearing seat is arranged on the upper wall of the shell, and a lower bearing seat is arranged on the lower wall of the shell; an upper bearing is arranged in the upper bearing seat, and a lower bearing is arranged in the lower bearing seat; a spindle is mounted between the upper bearing and the lower bearing, an isolating chamber is formed in the top of the shell, and the upper part of the upper bearing seat is covered with the isolating chamber; a negative pressure chamber communicating with an inner cavity ofthe shell is formed in the periphery of the isolating chamber and used for outwards conveying materials in the inner cavity of the shell; an air inlet is formed in the upper wall of the isolating chamber, and an air guiding pipe is arranged on the side wall, adjacent to the negative pressure chamber, of the isolating chamber; a cascade ring and a dustproof bowl cover are sequentially arranged onthe position, above the lower bearing seat, outside the spindle in a sleeving mode, as for the cascade ring, the diameter of the upper section is smaller than that of the lower section, and the bottomface of the cascade ring is pressed on the lower bearing seat and the top face of the lower bearing; and a sunken table is arranged on the inner wall of the lower section of the dustproof bowl cover,the dustproof bowl cover sleeves the top of the cascade ring, and the upper section of the cascade ring is embedded into the sunken table. The upper bearing can be prevented from being too hot, and the lower bearing can also be prevented from being blocked by dust.

Description

technical field [0001] The present invention relates to the technical field of drying equipment, and more specifically relates to a depolymerization equipment. Background technique [0002] Ultrafine dispersion is one of the important ways to improve the quality of micropowder and nanoparticles, but with the ultrafine and nanonization of micropowder particles, the smaller the particle size and the more atoms on the surface, the higher the surface energy and the adsorption effect. The stronger it is, according to the principle of minimum energy, the particles will agglomerate with each other, so that they cannot be well dispersed in the polymer matrix. At present, there are many nano-calcium carbonate products on the domestic market. They have indeed reached the nanometer level when detected under a scanning electron microscope, but in practical applications, their effect is not better than that of fine calcium carbonate. The reason is that nano-calcium carbonate has no Afte...

Problems solved by technology

In actual design, since the radial size of the vertical depolymerization equipment should not be too large, the material outlet is often designed adjacent to the bearing seat, and the depolymerization equipment often generates a lot of heat during the material crushing process, and the heat passes through When the material is discharged, it is often conducted to the upper bearing through the bearing seat, and the bearing itself will generate a lot of heat during high-speed operation, so it is easy to cause overheating damage to the bearing; in addition, because the powder is generally relatively fine, so the powder Powder can easily enter the lower bearing. If things go on like this, the lower bearing will be easily jammed by the powder. In severe cases, the main shaft will not be able to rotate.
