Description

Technical Field

[0001] This utility model relates to the field of glass microsphere production technology, specifically a distributed air-induced ventilation device and a glass microsphere production device. Background Technology

[0002] Glass microspheres refer to solid or hollow glass beads with diameters ranging from a few micrometers to a few millimeters, and can be colorless or colored. Beads with a diameter of 0.8 mm or more are called fine beads; those with a diameter of less than 0.8 mm are called microspheres.

[0003] Glass microspheres are a novel silicate material characterized by transparency, adjustable refractive index, directional retroreflection, smooth surface, good flowability, electrical insulation, chemical stability, heat resistance, and high mechanical strength. High-strength solid microspheres are mainly used as grinding media, abrasive materials in machining, and reinforcing fillers. Reflective solid microspheres are primarily used in traffic signs, art and advertising, marine lifesaving equipment, performance costumes, and directional projection screens. Hollow microspheres are mainly used in solid buoyancy materials, cryogenic insulation materials, engineering plastics, and solid rocket fuel fillers. They are widely used in light industry, chemical industry, textile industry, transportation, shipping, and precision machining industries.

[0004] During the formation of glass microspheres, the glass beads soften upon heating at the bottom of the vertical diffusion chamber. As the airflow rises, they continue to soften upon heating, shrink and round under the influence of liquid surface tension, and gradually cool and solidify into glass beads. The air inlet at the top of a traditional vertical diffusion chamber is a common pipe located in the middle of the top. Due to the influence of the pipe, the airflow path is conical during the upward movement of the airflow.

[0005] This results in a slow gas flow rate in many spaces inside the diffusion chamber, making it impossible to effectively produce glass beads; at the same time, the uneven gas flow rate leads to uneven sphericity and particle size distribution of the glass beads, resulting in a low yield.

[0006] Solving the above problems is an urgent issue that needs to be addressed by those skilled in the art. Utility Model Content

[0011] Furthermore, in the distributed air duct, the diameter of the duct near the edge is larger than the diameter near the center.

[0012] Furthermore, the present invention also discloses a glass microsphere production apparatus, wherein the glass microsphere production distributed air extraction device is provided on the top.
