Method for preparing glass beads by using recovery of waste glass powder

Abstract

The invention discloses a method for preparing glass beads by using recovery of waste glass powder. The method takes waste glass powder or glass beads powder as a raw material, and comprises the following steps: 1) mixing waste glass powder or / and waste glass beads and a corresponding material to obtain a powder mixture; 2) passing the powder mixture through a material spraying port and performingspray gun combustion flame material production, forming beads at high temperature, collecting the beads by a collection device, and separating the beads by a cyclone separator to the glass beads water-quenching powder; and 3) drying the glass beads water-quenching powder, separating the material by the separator for several times, and introducing the material in a dedusting collection device forcollection to obtain the glass beads. The glass beads prepared by using waste glass powder or waste and old glass beads powder as the raw materials have high reflection performance, provides high visibility as a road sign, greatly reduces the production cost of the glass beads, and realizes energy saving and environmental protection.

Description

Technical field: [0001] The invention relates to a method and a device for preparing glass microspheres, in particular to a method and a device for preparing glass microspheres without recycling waste glass microsphere powder. Background technique: [0002] Glass beads are widely used in light industry, chemical industry, textile, transportation, shipping, precision machining and other industries. For example, reflective glass beads are currently used in traffic signs and art propaganda in the market. Due to the strong reflective effect and reflective function of glass beads, more and more attention is paid by the market, so the application of glass beads is becoming more and more extensive. The actual demand in the market is also increasing. [0003] At present, there are many methods for preparing glass beads on the market, such as powder method, melt method, flame flotation method, etc., but they are all prepared from glass powder or chemical raw materials. In the proc...

Problems solved by technology

[0003] At present, there are many methods for preparing glass microspheres on the market, such as powder method, melt method, flame flotation method, etc., but they are all prepared from glass powder or chemical raw materials. In the process of beading, a large number of glass beads with a diameter of less than 30um are often produced. The glass bead powder with a diameter of less than 30um is usually called waste glass powder or waste glass bead powder. Bead powder is usually treated as waste, which not only causes a waste of resources, but also increases the production cost of glass beads. Therefore, the utilization of this waste glass bead powder is placed in front of glass bead manufacturers. A most fundamental practical subject
