Abstract
The invention relates to a glass microbead segmentation spheroidizing process capable of being less in glass microbead combination, less in crystal separation phenomenon and uniform in particle diameter distribution, and a spheroidizing gun. The spheroidizing process comprises the following steps: segmenting smashed SiO2 or Al2O3 with the particle diameter of 10mu m to 100mu m into three segments according to the particle diameters of 10mu m to 40mu m, 40mu m to 70mu m and 70mu m to 100mu m and then spheroidizing, namely, carrying out continuous spheroidizing production by regulating a flame temperature within 1500 DEG C to 1800 DEG C due to a small specific surface area and a weak spheroidizing flame during the spheroidizing of the fine material with the particle diameter of 10mu m to 40mu m; carrying out the continuous spheroidizing production by regulating the flame temperature within 1800 DEG C to 2100 DEG C due to a large specific surface area and a relatively strong spheroidizing flame during the spheroidizing of the fine material with the particle diameter of 40mu m to 70mu m; carrying out the continuous spheroidizing production by regulating the flame temperature within 2100 DEG C to 2500 DEG C due to the large specific surface area and the relatively strong spheroidizing flame during the spheroidizing of the fine material with the particle diameter of 70mu m to 100mu m.
Description
Technical field
The present invention relates to can to make glass microballon in a kind of glass microballon segmentation spheriodizing technique and pearl is few, crystallization is few, size distribution glass microballon segmentation spheriodizing technique and nodularization rifle more uniformly, belong to glass microballon and manufacture field.
Background technology
CN203333461U, title " glass microballon burner " comprise transfer lime, oxygen hose, gas line, feed opening, it is characterized in that: described feed opening is arranged at the end of transfer lime and connects with transfer lime inner chamber, described oxygen hose is arranged at the bottom of transfer lime inner chamber, the distance A of described oxygen hose head and transfer lime bottom is greater than the distance B of described feed opening and transfer lime bottom, and described gas line is arranged in the chamber wall of transfer lime.Its weak point: because gas line outlet is arranged on burner loudspeaker outlet skew wall, therefore both cannot realize even mixing the between combustion gas and oxygen, also cannot realize the rectification to mixed gas, cause the combustion flame temperature can not be constant, cause glass microballon shaping quality not guarantee.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design and a kind ofly can make glass microballon and pearl is few, crystallization is few, size distribution glass microballon segmentation spheriodizing technique and nodularization rifle more uniformly.
Design: in order to realize above-mentioned purpose of design.1, the starting material that adopt are the material powders after segmentation, according to carse, medium and small 3 particle diameter sections or thick, thin 2 particle diameter sections, carry out respectively the design of nodularization, are one of technical characterictics of the present invention.The object of design is like this: if when material powder carse, medium and small or thick, fine grain size section is carried out to nodularization, when glass microballon during in certain flame nodularization because coarse fodder and fines mix, there will be fines superfusion to cause and pearl, coarse fodder nodularization deficiency causes the phenomenon that physicals is not good, and the present invention carries out segmentation nodularization because the material size by nodularization is relatively consistent to glass microballon,, can there is not the not good phenomenon of nodularization physicals in the phenomenon of neither can superfusing yet.2, first mixing between combustion gas and oxygen, rear rectification in nodularization rifle, spraying the design of combustion technology scheme, is two of technical characterictic of the present invention again.The object of design is like this: both realized between combustion gas and oxygen and evenly having mixed, make again gas-flow before burning, obtain rectification, guaranteed the consistence of temperature of combustion and the consistence of gas-flow, and then made the quality of nodularization glass microballon obtain the raising of essence.
Technical scheme 1: a kind of glass microballon segmentation spheriodizing technique, SiO2 or the Al of employing 10-100 μ m
2o
3pulverize body according to particle diameter 10-40 μ m, 40-70 μ m, is divided into three sections after 70-100 μ m segmentation and carries out respectively nodularization, when adopting the nodularization of 10-40 μ m fines, because specific surface area is less, nodularization flame is relatively little, and while regulating 1500-1800 ℃ of flame temperature, continuous balling is produced; In adopting 40-70 μ m, during coarse fodder nodularization, because specific surface area is larger, nodularization flame is relatively large, regulates 1800-2100 ℃ of continuous balling of flame temperature to produce; When adopting the nodularization of 70-100 μ m coarse fodder, because specific surface area is larger, nodularization flame is relatively large, regulates 2100-2500 ℃ of continuous balling of flame temperature to produce.
Technical scheme 2: a kind of glass microballon segmentation nodularization rifle, rifle body top is communicated with by blanking control valve with blanking bin, rifle body tail end is respectively equipped with oxygen inlet mouth and gas inlet, oxygen inlet mouth is communicated with the oxygen control valve that is positioned at rifle body middle part, gas inlet is communicated with the gas control valve that is positioned at rifle body middle part, and rifle mouth is equipped with in gun barrel end.
The present invention compares with background technology, and the one, solved cannot evenly mix between combustion gas that background technology exists and oxygen, cannot rectifier have caused the combustion flame temperature can not be constant, the unwarrantable defect of glass microballon shaping quality that causes; The 2nd, also pearl and the unwarrantable defect of nodularization physicals that while having solved glass microballon nodularization, have occurred.
