Fluidized bed mixing device for mortar production

Abstract

The invention discloses a fluidized bed mixing device for mortar production. The lower portion of a mixing chamber is in a cylinder shape, the upper portion of the mixing chamber is of a taper structure, an air chamber is fixed to the lower end of the mixing chamber, an air distributing plate is fixed between the mixing chamber and the air chamber and is provided with an air inlet hole, the mixingchamber communicates with the air chamber through the air inlet hole, a plurality of sets of feeding spiral conveyors are installed on the side wall of the lower portion of the mixing chamber, an annular air distributing sleeve is installed on the outer side of the middle portion of the mixing chamber, an inner cavity of the air distributing sleeve communicates with the mixing chamber through a through hole of the mixing chamber, the mixing chamber is connected with an inlet of a cyclone separator through a discharging pipe, an air outlet of the cyclone separator is connected with an air inlet of a bag-type dust collector, discharging openings of the cyclone separator and the bag-type dust collector are both connected with a finished product hopper through discharging pipes, and the discharging pipes are provided with star dischargers. The fluidized bed mixing device has the advantages of being clean, environment-friendly and good in mixing uniformity.

Description

technical field [0001] The invention belongs to the technical field of building material production, and in particular relates to a fluidized bed mixing device for mortar production. Background technique [0002] Inorganic thermal insulation mortar uses inorganic light aggregates (such as hydrophobic expanded perlite, vitrified microbeads, closed-cell perlite, expanded vermiculite, pottery sand, etc.) It is a building thermal insulation dry powder mortar mixed with high molecular polymer and functional additives. The mortar production process will involve a lot of mixing of materials and powders. The existing mixing technology is mainly through the mixer, and the stirring device is mostly driven by a motor. The existing mixing device mainly has poor mixing uniformity and poor operation stability. Defects, but also the defect that it is easy to generate dust. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficie...
