Description
Technical field
The present invention relates to glass microballoon raw material sectioning and technique that a kind of glass microballoon raw material carry out segmentation screening collection, belong to glass microballoon and manufacture field.
Background technology
Existing glass microballoon spheroidizing process is on raw ore basis, carries out melt, material powder that shrend, pulverizing are formed afterwards, then carries out the handling processes such as flame nodularization, pickling or alkali cleaning, washing, annealing, screening.Due to existing glass microballoon material powder due to domain size distribution too wide, powder particle out-of-shape, be not easy to realize segmentation, there will be fines superfusion to cause and pearl when glass microballoon is in certain flame nodularization, coarse fodder nodularization deficiency causes physical property not good, and large pearl when simultaneously microballon uses, globule use amount seldom cause stock and melt down and the waste that causes for raw material carries out secondary.
Summary of the invention
Purpose of design: avoid the weak point in background technology, the material powder designing a kind of glass microballoon carries out glass microballoon raw material sectioning and the technique of segmentation screening by different-grain diameter scope.
Design: in order to realize above-mentioned purpose of design.The present invention is in structural design, under the prerequisite not having new wind to supplement, material powder enters in feed line by tremie pipe, hydrodynamics rule is presented at the end of feed line, namely maximum at pipe central authorities flow velocity, the flow velocity that pipe two is surveyed is zero, the fluid that it is zero that the meaning that its new wind supplements is to this flow velocity provides a flow velocity continued forward, otherwise what collect at nearest feed opening place will be the raw material that sized particles mixes, lose the meaning of raw material segmentation, this is the core realizing this device and technique.Secondly, whole stages process both can realize continued operation also can intermittently operated, not only easy to operate, and the uniform segmentation of raw material can be realized, if realize continued operation, the bottom of collecting box must ensure all have certain gradient at the left and right sides of discharging opening, ensures that the material powder after segmentation is flowed out by discharging opening smoothly.
Technical scheme 1: a kind of glass microballoon raw material sectioning, tremie pipe inserts in feed line and tremie pipe tube wall and feedstock transportation tube wall are sealed and matched, feed line one end is relative with conveying blower outlet, wind speed supplements pipe box on feedstock transportation tube wall and wind speed supplements inside pipe wall and feed line outer wall forms unidirectional wind-guiding air channel, airduct one end and wind speed supplement pipe and are communicated with, the other end is relative with blower outlet, material collection case Single port and wind speed supplement pipe and export tube wall and be tightly connected, bulky grain discharging opening is had bottom material collection case, in a material discharging opening and granule discharging opening.
Technical scheme 2: a kind of glass microballoon raw material stages process, raw material enter feed line by charge door and valve along tremie pipe, under the effect of conveying air blast air pressure, powder moves forward, new wind supplements and enters the supplementary pipe of wind speed by air blast along blower, the new wind supplemented provides energy to powder, make originally on hydrodynamics near pipe side speed be zero fluid have continuation speed forward, powder does fluid conveying forward under distinguished and admirable effect, after entering collecting box, bulky grain drops on large discharging opening nearby, middle particle drops on the middle particle discharging opening in large discharging opening front, granule drops on the discharging opening in middle particle discharging opening front, realize thus raw-material Fractional Collections.
The present invention is compared with background technology, one is achieve the raw-material segmentation screening of glass microballoon and collect, solve background technology exist due to powder particle out-of-shape, there will be fines superfusion to cause and pearl when glass microballoon is in certain flame nodularization, the phenomenon that coarse fodder nodularization deficiency causes physical property not good; Two is that point wind is effective, avoids the phenomenon that small size particle falls into large-size particles outlet, ensure that the relative uniformity of selection by winnowing particle size range; Three is be not only applicable to the reflective industry that refractive index is more than 1.93 and 2.5, is also applicable to the glass microballoon other industry of middle low-refraction.
