By material: they can be divided into ordinary glass microspheres, borosilicate glass microspheres, quartz glass microspheres, etc. Different materials of glass microspheres have different performance characteristics to meet specific application requirements. By density: they are divided into low-density glass microspheres, medium-density glass microspheres, and high-density glass microspheres. Low-density glass microspheres are mainly used for weight reduction applications, while high-density glass microspheres can be used in some special applications requiring high-density materials. By use: there are reflective glass microspheres, heat-insulating glass microspheres, and abrasive glass microspheres, etc. Reflective glass microspheres are used in road markings, traffic safety facilities, etc., improving nighttime visibility; heat-insulating glass microspheres have good thermal insulation properties and are often used in insulation materials; abrasive glass microspheres are used in grinding, polishing, and other processes.

[0003] In the existing technology, grading sieves are usually used when producing glass microspheres. However, a large amount of dust may be adsorbed on the surface of the glass microspheres during production. Therefore, during screening, the dust may be adsorbed on the inner wall of the screening device. Due to the setting of the screen and other components inside the screening device, it is inconvenient for workers to clean, which increases the cleaning difficulty. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4 As shown, this utility model provides a multi-layer glass microsphere grading sieve, including a box body 8. Support grooves 18 are provided on both sides of the box body 8. Support plates 17 are slidably installed inside each of the two support grooves 18. Multiple evenly distributed collection frames 20 are arranged between the two support plates 17. Multiple evenly distributed through holes 21 are provided through the inner wall of each collection frame 20. A fixing frame 16 is fixedly installed on the top of each of the two support plates 17. Connecting plates 9 are fixedly installed on both sides of the outer side of the fixing frame 16. A storage groove 11 is provided on the outer wall of the connecting plate 9. A threaded hole 12 is provided through the inner wall of the storage groove 11. A threaded rod 13 is threadedly connected inside the threaded hole 12. A handle 14 is fixedly installed at one end of the threaded rod 13, and a connecting block 15 is movably connected to the end of the threaded rod 13 away from the handle 14. Connecting grooves 10 are provided on both sides of the outer side of the box body 8.

[0023] The effect achieved by the entire embodiment 1 is that when the screening is finished, the operator rotates the two handles 14, which drives the threaded rod 13 to rotate, so that the threaded rod 13 moves along the threaded hole 12, thereby driving the connecting block 15 away from the connecting groove 10. At this time, the operator pulls the two connecting plates 9, and the connecting plates 9 drive the two support plates 17 away from the box 8 through the fixed frame 16, thereby driving the collection frame 20 away from the box 8. In this way, it is convenient for the operator to clean the inner wall of the box 8 and improve the cleaning efficiency.

[0024] Example 2, as Figures 1-4 As shown, further, the outer wall of the support plate 17 is provided with a plurality of evenly distributed slots 22, and the outer sides of the collection frame 20 are fixedly installed with insert plates 23, and the top of the insert plates 23 is provided with slots 25.

[0025] Furthermore, a limiting groove 26 is provided inside the support plate 17. A second spring 27 is fixedly installed on the top surface inside the limiting groove 26. A lifting plate 28 is fixedly installed at the bottom of the second spring 27. An L-shaped groove 30 is provided through the inner side wall of the limiting groove 26 and multiple slots 22. An L-shaped plate 31 is fixedly installed at one end of the lifting plate 28 near the L-shaped groove 30. A moving rod 29 is fixedly installed on the top of the lifting plate 28. The tops of the two moving rods 29 pass through the support plate 17 and are fixedly installed with a pull frame 19.

[0026] Furthermore, a base 1 is provided on the outside of the box body 8. Two first springs 3 are fixedly connected between the outer sides of the box body 8 and the inner sides of the base 1, respectively. Limiting rods 4 are fixedly installed on both outer sides of the box body 8. One end of the limiting rod 4 is slidably inserted into the base 1. The limiting rod 4 is used to limit the box body 8 and prevent the box body 8 from tilting.

[0027] Furthermore, a fixing plate 5 is fixedly installed on the top of the base 1, and a motor 6 is fixedly installed on the outer wall of the fixing plate 5. The output end of the motor 6 passes through the fixing plate 5 and is fixedly installed with a cam 7.

[0028] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the base 1.

[0029] Furthermore, a discharge hopper 24 is fixedly installed at the bottom of the box 8.

[0030] The effect achieved by the entire embodiment 2 is that during collection, the staff pulls the pull frame 19, and the pull frame 19 drives the lifting plate 28 to rise through the two moving rods 29, thereby driving the L-shaped plate 31 to leave the slot 25. At this time, the staff can pull the insert plate 23 out of the slot 22, remove the collection frame 20, and collect and recycle the glass microspheres, which is convenient for disassembly.

[0031] Working principle: During use, the operator places the glass microspheres inside the housing 8. The operator then starts the motor 6, whose output drives the cam 7 to rotate. When the cam 7 contacts the housing 8, it pushes the housing 8 to move. The first spring 3 on one side of the housing 8 stretches, while the first spring 3 on the other side compresses. When the cam 7 no longer contacts the housing 8, the elastic force of the first spring 3 causes the housing 8 to return to its original position. This back-and-forth motion causes the housing 8 to shake continuously, increasing the screening efficiency. After being screened through multiple sets of different through-holes 21, the glass microspheres finally exit from the discharge hopper 24. At the end of screening, the operator rotates the two handles 14, which drive the threaded rod 13 to rotate, causing it to move along the threaded hole 12. This, in turn, moves the connecting block 15 away from the connecting groove 10. The operator then pulls the two connecting plates 9, which, through the fixed frame 16, move the two support plates 17 away from the housing 8, and consequently, the collection frame 20 away from the housing 8. This facilitates cleaning of the inner wall of the housing 8, improving cleaning efficiency. During collection, the staff pulls the pull frame 19, which drives the lifting plate 28 to rise through two moving rods 29, thereby causing the L-shaped plate 31 to leave the slot 25. At this time, the staff can pull the insert plate 23 out of the slot 22, remove the collection frame 20, and collect and recycle the glass microspheres, which is convenient for disassembly.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
