A spheroidizing device for hollow microspheres

Abstract

The invention relates to a hollow microsphere spheroidization device, which comprises a spheroidization chamber (1), a solution tank (2) is arranged on the upper surface of the spheroidization chamber, and an outlet (2a) is arranged on the bottom of the solution tank. There is also a molten liquid (4) and an air inlet pipe (3), which are connected to the collector (13) on one side of the spheroidization chamber, and are characterized in that: the rotating shaft (7) is vertically connected in the spheroidizing chamber, and the upper and lower ends of the rotating shaft The cutter (8) and the motor (14) are respectively connected; the side air source (10) and the lower air source (11) are also included, and the side air source and the lower air source are respectively connected to the side air nozzle (5) and the lower air nozzle (6) , the side air nozzle and the down air nozzle are all set through the side wall of the spheroidizing chamber. Advantages of the present invention: when the device prepares large-diameter hollow microspheres, the hollow microspheres achieve a good spheroidization effect, and the hollow microspheres have the characteristics of uniform inner wall and uniform compressive strength, which greatly improves the performance of the hollow microspheres. physical properties and expand its application fields.

Description

technical field [0001] The invention relates to a spheroidizing device, in particular to a spheroidizing device for hollow microspheres. Background technique [0002] At present, the lightweight concrete and refractory concrete required in the construction, cement industry, and traditional lightweight aggregate industries in China basically use ceramic particles as lightweight aggregates. The process will bring some insurmountable difficulties, and lightweight concrete is a must for the construction industry. At present, according to the query of relevant information, the preparation process of large-diameter hollow glass microspheres mainly includes sintering method, melt blowing method and so on. The strength of the microspheres prepared by the sintering method is low, and the open-pore structure of the microspheres will be formed during the process, so that the water absorption rate will be large, etc. For the melt-blowing method, the microspheres will also lose weight d...
