Summary of the invention
In order to solve in prior art the collision problem between microballoon and Pan Bi in microsphere surface coating process, microballoon.The utility model provides a kind of air-flotation type microballoon running gear.
The technical solution of the utility model is
Air-flotation type microballoon running gear of the present utility model, is characterized in, described device comprises microballoon dish, gas distribution cup, rubber buffer ring, air inlet rubber tubing, support, gas distribution cup tray.Wherein, described gas distribution cup contains the multipath gas outlet of multipath gas pipeline and correspondence, and gas distribution cup tray is provided with a circular hole, and circular hole is provided with rubber buffer ring.Its annexation is, described microballoon dish is fixedly connected with gas distribution cup upper end, microballoon dish is provided with the aperture corresponding with pneumatic outlet in gas distribution cup.Described gas distribution cup tray is fixedly connected with support by retaining screw, and gas distribution cup lower end is through the circular hole in gas distribution cup tray and air inlet rubber tubing nested encryptions.Gas distribution cup tray is fastenedly connected by the outer wall of rubber buffer ring and gas distribution cup lower end.
Gas piping in described gas distribution cup comprises four rows arranged along gas distribution cup inner periphery and becomes the pipeline of 30 ° of angles with vertical direction and arrange pipeline parallel to the vertical direction more.
In described gas distribution cup, pneumatic outlet aperture is 200 μm ~ 1000 μm.
The utility model adopts suitable outlet aperture according to different microsphere diameter, and microballoon dish is hemispherical.Four row's gas pipings of circumference outer and vertical direction are the angle of 30 °, ensure that microballoon not easily departs from gas and directly flows out region in resuspension procedure, thus maintain the suspended motion being about 2cm region from center of circle certain radius to produce centripetal air-flow.
The utility model utilizes working gas in gas piping or rare gas element as the carrier of microballoon suspension random motion, by the flow of adjustments of gas to adapt to the microballoon of different diameter, go out to make microballoon to be suspended in microballoon dish by gas stream, and with random spinning motion.The diameter of the height that microballoon suspends in microballoon dish and microballoon, the quality of microballoon are closely related, the rotational velocity of microballoon in microballoon dish and gas flow rate, microsphere diameter size are relevant with microspheres quality, the direction of microballoon rotation because of good concentricity, the evenness of wall thickness of microballoon, the small sample perturbations of gas flow rate or the flow direction and changing at random.
The utility model avoids collision between microballoon, between microballoon and sample disc or friction problem, effectively can reduce the problem of microsphere surface coating roughness.
