The transmission mechanism 5 includes a transmission belt 52 and two transmission rollers 51. The surface of the transmission belt 52 is provided with a water filter hole 521, and the diameter of the water filter hole 521 is smaller than the diameter of the hollow glass microbeads. A plurality of baffles 522 are arranged on the surface of the transmission belt 52. The collection frame 6 is located directly below one end of the transmission mechanism 5. A feed port 16 is arranged on the outer top of the screening frame 1, and two speed reduction plates 161 are hingedly matched on the inner wall of the feed port 16. An arc spring 162 is fixedly connected between the bottom of the two speed reduction plates 161 and the inner wall of the feed port 16, and a rotary feeder 163 is arranged at the bottom of the feed port 16.

[0030] During the use of the separation and bleaching equipment, the specific operation process of the equipment is: first, hollow glass beads are added to the feed port 16 set above the screening frame 1 to screen the raw materials, and then the raw materials of the beads fall onto the screening plate 11 set on the inner wall of the screening frame 1 for screening, and the cleaning plate 12 is started to clean the surface of the raw materials of the beads, and then the raw materials of the beads fall along the screening plate 11 into the cleaning trough frame 2 for secondary cleaning, and then the raw materials of the beads enter the mixing frame 3 along the lower hopper 203 to fully mix the raw materials of the beads and the water medium, and then the raw materials of the beads enter the stilling pool 4 along the channel between the mixing frame 3 and the stilling pool 4, and the beads with a specific gravity greater than that of the water medium are precipitated at the bottom of the water, while the beads with a specific gravity less than that of the water medium float on the water surface and pass through the baffle plate 42 directly above to enter the conveyor belt 52, and finally the beads are transmitted to the collection frame 6 set directly below the end of the transmission mechanism 5 through the conveyor belt 52.

[0031] Impurities in the water can affect buoyancy, mainly in the following aspects: First, change the density of water: when water contains impurities, its density will change. If the density of the impurities is greater than that of water, the overall density of water will increase; conversely, if the density of the impurities is less than that of water, the overall density of water will decrease. Second, the influence of the surface tension of the liquid: the presence of impurities may change the surface tension coefficient of water. Surface tension is a characteristic of the liquid surface, which has a certain influence on the buoyancy of objects on the liquid surface. Some impurities may reduce the surface tension of water, making it easier for objects to spread and float on the water surface, while other impurities may increase the surface tension of water, making it more difficult for objects to float on the water surface. Third, change the volume of water displaced by the object: impurities in the water may adhere to the surface of the object, thereby changing the volume of water displaced by the object. According to Archimedes' principle, the buoyancy of an object is equal to the gravity of the water it displaces, so changes in the volume of water displaced will cause changes in buoyancy. In summary, impurities in water affect the size of buoyancy in many ways. Therefore, in application scenarios involving buoyancy, it is necessary to fully consider the impact of impurities in water on hollow glass microspheres to ensure accurate understanding and prediction of changes in buoyancy.

[0032] In the present invention, it is not only necessary to clean the microbead raw material in the screening frame 1 and the cleaning tank frame 2 to reduce impurities on the surface of the microbead raw material and reduce the buoyancy change of the microbead raw material entering the static pool 4, but also it is necessary to add a water density meter in the static pool 4. When the water density does not meet 1±0.005g / cm³, the water in the static pool 4 is replaced in time.

[0033] The microbead raw material is added into the feed port 16, and the two deceleration plates 161 hingedly matched with the microbead raw material and the inner wall of the feed port 16 are in contact and squeezed with each other, so that the two deceleration plates 161 rotate downward at the same time and the arc spring 162 fixedly connected between the deceleration plate 161 and the inner wall of the feed port 16 is compressed, which produces an upward buffering force on the microbead raw material, which can slow down the falling of the microbeads and prevent the microbead raw material from falling directly on the screening plate 11 and causing damage due to excessive impact force. In addition, a rotary feeder 163 is arranged at the bottom of the feed port 16. The rotary feeder 163 is a rotor with several blades that rotates in a cylindrical casing. The material falls from the upper hopper and fills the space between the blades. It is discharged as the blades rotate to the bottom, which can feed evenly and continuously, and can evenly spread the microbead raw material to avoid accumulation in one place.

[0034] The microbead raw material falls onto the screening plate 11 arranged on the inner wall of the screening frame 1 for screening, and the cleaning plate 12 is started to clean the surface of the microbead raw material. Specifically, by starting the servo motor 17 fixedly installed on the outer wall of the screening frame 1, the first central axis 115 fixedly connected to the output end of the servo motor 17 is driven to rotate, so that the second rotating plate 114 and the second fixed axis 113 rotate around the first central axis 115. Through the cooperation of the first rotating plate 112 and the second rotating plate 114, the first fixed axis 111 is driven to move up and down, and the screening plate 11 is driven to slide back and forth between the plurality of lifting slots 13, so that qualified microbeads are screened out through the screening plate 11, and the situation that some unqualified microbeads are mixed in the hollow glass microbeads with a specific gravity less than 1 and separated is reduced. Qualified microbeads are some microbeads with surface damage and breakage or microbeads smaller than normal size. The maximum diameter of unqualified microbeads is smaller than the aperture on the screening plate 11. They also pass through a number of water nozzles arranged at the bottom of the cleaning plate 12. When the screening plate 11 moves up and down, the screening plate 11 that moves up and down can turn the microbeads over in time, thereby improving the cleaning efficiency of the surface of the microbead raw material and avoiding the situation where impurities stick to the surface of the microbead raw material and the specific gravity is greater than the water medium 1, which is beneficial to the subsequent separation and rinsing in the static pool 4. The screening plate 11 that moves up and down also avoids the problem of blockage of the screening plate 11 by the microbeads. The dirty water and microbead fragments filtered during the screening process converge into the discharge trough 14 along the screening frame 1, and are then discharged from the second discharge valve 141 arranged at the bottom of the discharge trough 14.

[0035] The microbead raw material falls along the screening plate 11 into the cleaning trough frame 2 for secondary cleaning. The cleaning trough frame 2 is arranged in an arc shape, and the inner bottom is provided with water that can prevent the cleaning trough frame 2 from overflowing, thereby improving the cleanliness of the microbead raw material.

[0036] The microbead raw material enters the mixing and stirring frame 3, and the previously cleaned microbead raw material and the water medium in the mixing and stirring frame 3 are fully mixed to facilitate the subsequent separation and bleaching steps.

[0037] The microbead raw material enters the static pool 4. In addition to the hollow glass microbeads floating on the water surface, there are also some microbeads with a specific gravity greater than and close to 1 that sink below the water surface. After the length of the connecting rope 421 is selected according to the water surface height, the two ends of the connecting rope 421 are fixed with knots, and the two knots after fixation are respectively fixed to the bottom of the air bag 422 and the top of the baffle plate 42, so that the two connecting ropes 421 fixed on the top of the baffle plate 42 can be adjusted in length. Through the arrangement of the baffle plate 42, the connecting rope 421 with adjustable length and the air bag 422, the upper and lower positions of the baffle plate 42 can be automatically adjusted according to the liquid level. The baffle plate 42 can isolate the microbeads with a specific gravity close to 1 that float on one side of the static pool 4 and are located below the liquid surface. The structure is simple, and the bleaching efficiency of the microbeads is improved; and the microbeads with a specific gravity greater than 1 can sink to the bottom of the static pool 4.

[0038] After the microbeads pass through the top of the baffle plate 42, the conveyor belt 52, the filter holes 521 and the baffle plate 522 are arranged to drain the liquid on the surface of the microbeads and transfer the drained microbeads to the collection frame 6 for collection.

[0039] By integrating the screening, cleaning and bleaching of microbead raw materials, the separation and bleaching of hollow glass microbeads was finally achieved.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
