Vitrified micro-bead and Songmiwei platinum production equipment

Abstract

The invention relates to vitrified micro-bead and Songmiwei platinum production equipment. The production equipment comprises an expansion furnace and a preheating furnace, wherein the expansion furnace comprises a heat preservation layer, a fireproof layer and a high-temperature-resistant furnace pipe, the upper end of the high-temperature-resistant furnace pipe is connected with a feeding hopper, and a plurality of low-nitrogen combustors are further arranged on the side wall of the expansion furnace; the preheating furnace comprises an outer shell and a central rotary drum, a first spiral blade is arranged on the inner wall of the central rotary drum, a second spiral blade is arranged on the outer wall of the central rotary drum, and the rotating direction of the first spiral blade is opposite to that of the second spiral blade; one end of the central rotary drum is provided with a finished product feeding port, and the other end is connected with a finished product discharging port. One end of the outer shell is provided with a raw material preheating inlet and one end is provided with a raw material preheating outlet. Cooling of high-temperature finished product particles andpreheating of to-be-preheated raw material particles can be achieved at the same time, energy consumption in the expanded and vitrified micro bubble machining process can be effectively reduced, energy is saved, continuous production operation can be achieved, and the production efficiency is high.

Description

Technical field [0001] The invention relates to an expanded perlite production equipment, in particular to a production equipment for vitrified microbeads and pine-viplatin. Background technique [0002] Vitrified beads (closed-cell expanded perlite) is an inorganic vitreous mineral material. High-quality pine-dimensional platinum is also called pine-lime platinum; vitrified beads are perlite ore preheated and instantaneously roasted at high temperature After expansion, it is a white granular material with a honeycomb structure inside, which is irregular spherical particles, an internal porous cavity structure, a closed surface with vitrification, smooth luster, stable physical and chemical properties, light weight, heat insulation, Excellent characteristics such as fire resistance, high and low temperature resistance, aging resistance, low water absorption, etc., can replace the application of many traditional lightweight aggregates such as fly ash float beads, glass beads, expa...
