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 make in a kind of glass microballoon segmentation spheroidizing process glass microballoon and pearl is few, crystallization is few,
The more uniform glass microballoon segmentation spheroidizing process of particle diameter distribution and nodularization rifle, category glass microballoon manufacture field.
Background technology
CN203333461U, title " glass microballoon burner " include delivery pipe, oxygen hose, Gas Pipe, feed opening, and it is special
Levy and be：Described feed opening is arranged at the end of delivery pipe and connects with conveying tube cavity, and described oxygen hose is arranged at
The bottom of conveying tube cavity, described oxygen tube head is more than described feed opening and delivery pipe with conveying bottom of the tube apart from A
Bottom apart from B, described Gas Pipe is arranged in the cavity wall of delivery pipe.Its weak point：Because Gas Pipe outlet is arranged on
On burner horn outlet skew wall, thus both cannot realize between combustion gas and oxygen it is uniform mix, also cannot realize to gaseous mixture
The rectification of body, causes combustion flame temperature constant, cause glass microballoon shaping quality it cannot be guaranteed that.
The content of the invention
Purpose of design：Avoid the weak point in background technology, design one kind can make glass microballoon and pearl is few, crystallize is existing
As less, particle diameter distribution more uniform glass microballoon segmentation spheroidizing process and nodularization rifle.
Design：In order to realize above-mentioned purpose of design.1st, the raw material for adopting is the material powder after segmentation, is pressed
Carry out the design of nodularization respectively according to carse, medium and small 3 particle diameter sections or thick, thin 2 particle diameter sections, be the present invention technical characteristic it
One.So design purpose be：If carse, medium and small or thick, fine grain section material powder is carried out into nodularization, work as glass
Microballon is in certain flame nodularization because coarse fodder and fines are mixed, it may appear that fines superfusion causes and pearl, coarse fodder ball
Change deficiency and cause the not good phenomenon of physical property, and the present invention carries out being segmented nodularization due to big by the material of nodularization to glass microballoon
It is little relatively uniform, superfusion phenomenon both will not occur, the not good phenomenon of nodularization physical property also will not occur.2nd, combustion gas in nodularization rifle
First mixing between oxygen, rear rectification, the design for spraying combustion technology scheme again, be the present invention technical characteristic two.So set
The purpose of meter is：Both realized between combustion gas and oxygen and uniformly mixed, and made combustion gas stream obtain rectification before combustion again, it is ensured that
The concordance of ignition temperature and the concordance of combustion gas stream, and then make the quality of nodularization glass microballoon obtain the raising of essence.
Technical scheme 1：A kind of glass microballoon is segmented spheroidizing process, using 10-100 μm of SiO2 or Al2O3Grinding bodies is pressed
According to 10-40 μm of particle diameter, 40-70 μm, being divided into three sections after 70-100 μm of segmentation carries out respectively nodularization, when using 10-40 μm of fines ball
During change, because specific surface area is less, nodularization flame is relatively small, continuous balling production when adjusting flame temperature 1500-1800 DEG C；
When coarse fodder nodularization in using 40-70 μm, because specific surface area is larger, nodularization flame is relatively large, adjusts flame temperature 1800-
2100 DEG C of continuous balling productions；When using 70-100 μm of coarse fodder nodularization, because specific surface area is larger, nodularization flame is relatively
Greatly, the production of flame temperature 2100-2500 DEG C continuous balling is adjusted.
Technical scheme 2：A kind of glass microballoon is segmented nodularization rifle, and gun body top is connected with blanking bin by blanking control valve,
Gun body tail end is respectively equipped with oxygen air inlet and gas inlet, and oxygen air inlet connects with the oxygen control valve being located in the middle part of gun body
Logical, gas inlet is connected with the gas control valve in the middle part of gun body, and gun barrel end is equipped with rifle mouth.
Compared with background technology, one is to solve cannot uniformly mix between the combustion gas of background technology presence and oxygen to the present invention
Close, cannot combustion flame temperature caused by rectification can not be constant, the glass microballoon shaping unwarrantable defect of quality caused by institute；
Two is to solve occur during glass microballoon nodularization and pearl and the unwarrantable defect of nodularization physical property.
