The driving shaft on the driving paddle 5 is connected with a driving motor, the driving motor is arranged on the lower side of the bearing frame, and the bearing frame is fixed on the ground through foundation bolts. The bearing frame is of an inverted U-shaped structure. And the driving motor is fixed on the cross beam of the inverted U-shaped structure of the bearing frame.
Filling liquid is arranged in the flotation water tank 1, the filling liquid comprises colored liquids with different densities and incompatible colors, and the liquid level of the filling liquid is higher than the average height of the feeding side plate 2.
And the filling liquid selects colored liquid with corresponding density according to the hollow beads of the hollow glass beads and the relative density at different filling rates.

The blade A9 and the blade B10 are made of rubber.
The drive motor acts on the immersion cylinder 4 via the reduction mechanism to effect counter-clockwise rotation of the immersion cylinder 4.
By adopting the PP cotton cylinder, the economic cost is considered, the water permeability and the blocking efficiency to the hollow glass beads are considered, and the construction cost of the device is further reduced.
When flotation operation is carried out, the hollow glass bead raw materials are fed along the feeding side plate 2, and the hollow glass beads are poured onto the feeding side plate 2. On the feeding side plate 2, the hollow glass beads enter the filling liquid, the hollow glass beads are mixed with the redundant residues and waste particles produced by the hollow glass beads, and the ultrasonic generator 3 utilizes the high-frequency vibration of the vibration head to act on the surfaces of the hollow glass beads through the filling liquid, so that the surfaces of the hollow glass beads are cleaned.
The immersion grooves formed in the immersion roller 4 capture hollow glass beads, the immersion roller 4 rotates anticlockwise under the action of the driving motor through the speed reducing mechanism, and the hollow glass beads captured in the immersion grooves rotate downwards along with the immersion grooves until the hollow glass beads in the immersion grooves are completely immersed by the filling liquid. Then, along with the continuous rotation of the immersion roller 4, until the hollow glass beads are separated from the limit of the immersion groove, a large amount of filling liquid can be poured into the hollow glass beads with cracks and damages on the surface in the process, so that the dead weight of the hollow glass beads is increased and the hollow glass beads begin to sink.

When the driving motor arranged on the bearing frame runs, the driving paddle 5 is driven to rotate and separate. The interaction between the coaxial reverse blade A9 and the blade B10 arranged on the driving paddle 5 generates disordered and disordered relative fluid postures, and the purposes of fully separating and mixing the raw materials of the hollow glass microspheres are achieved. The phenomenon that due to the expansion of water, a large number of hollow glass microspheres are gathered into a cluster, and are suspended or floated in the flotation water tank 1, the densities of the microspheres are mutually influenced and cannot be identified, and the flotation efficiency and accuracy are influenced is avoided.
When the driving paddle 5 rotates, the hollow glass beads further move towards the guide groove partition plate 7 under the action of centrifugal force. Due to the blocking phenomenon of the baffle 7 of the diversion trench, the filling liquid tends to move stably at different heights in the flotation water tank 1 in the area far away from the driving paddle 5, and the hollow glass beads move to the height of the filling liquid with corresponding density according to the relative density of the hollow glass beads.
The fragments of the hollow glass beads pass through the screening net 11 under the action of sedimentation, so that the fragments of the hollow glass beads are selected.
When the hollow glass beads move to the height of the liquid level of the corresponding colored liquid, the propeller motor 8 is driven to operate, and the filling liquid is driven to act on the hollow glass beads to generate thrust to the hollow glass beads, so that the hollow glass beads move towards the direction of the collecting tank 6. Under the action of thrust, the hollow glass microspheres roll through the blocking triangular prism to realize the screening of the hollow glass microspheres. Under the action of the grid baffle 13, the hollow glass beads cannot pass through the grid baffle 13, so that the hollow glass beads and the filling liquid are separated, the filling liquid is acted on thrust generated by the hollow glass beads which are not collected by the driving propeller motor 8 again, and closed-loop motion of the filling liquid in the diversion trench partition plate 7 is realized. Because the hollow glass microballoons are obstructed by the obstruction and cannot move to the flotation water tank 1 again, the flotation of the hollow glass microballoons is realized.
And the collecting bin independently stores the glass hollow microspheres classified by flotation. Further improving the working efficiency of the collecting tank 6.
