Description

Technical Field

[0001] The utility model relates to the technical field of alumina hollow sphere production, in particular to a diversion device for alumina hollow sphere production. Background Technique

[0002] Alumina hollow sphere is a new type of high-temperature heat insulation material, and its crystal form is a-A1203 microcrystal. With alumina hollow sphere as the main body, various shaped products can be made. The highest service temperature is 1800 degrees Celsius. The mechanical strength of the products is high, several times that of general light products, while the bulk density is only half of that of corundum products.

[0003] Alumina hollow spheres are generally produced by the melting and spraying method. The raw materials are directly melted in an electric arc furnace. After all the raw materials are melted, the furnace body is tilted, and the melted raw materials flow into the flow port from the diversion groove. At the same time, the air pressure valve is opened, and the liquid flow is blown into droplets by compressed air. Due to the action of melt viscosity and surface tension, the droplets quickly solidify during flight to form shell-shaped spheres, which are collected in the collection chamber, and then qualified finished products are obtained through sorting, screening or rinsing.

[0004] The existing diversion device for alumina hollow sphere production generally conducts diversion operations through a diversion groove. However, after the existing diversion groove is used for a long time, the inner wall of the diversion groove is prone to scale formed by melted raw materials, and the diversion groove needs to be cleaned. The existing cleaning method usually uses a scraper to scrape off the scale, and some hard scale deposits cannot be scraped off by the scraper, resulting in incomplete cleaning. Moreover, after the scraper is used, impurities may remain, which will also affect the production quality of alumina hollow spheres when mixed with the raw materials. Therefore, a diversion device for alumina hollow sphere production is proposed. Content of the Utility Model
