Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand, in particular to a vibrating screen for producing and processing fused quartz sand. Background Art

[0002] Fused silica sand is the product of quartz mineral precipitation after high-temperature smelting. It is a white, granular solid substance with a quartz content of up to 99%. Fused silica sand is a glassy material melted at high temperatures. It has many excellent physical and chemical properties, which has led to its widespread application in many fields.

[0003] The grit size of fused quartz sand is inconsistent during the production process. Particles of different sizes need to be further screened to select fused quartz sand of different qualities. Vibrating screens are needed in the selection process, but existing vibrating screens have the following problems:

[0004] First, when gravel is poured onto the vibrating screen, a sand pile is formed. The sand pile is very high but the screening area is small, which affects the screening efficiency. In addition, the gravel is easy to clump together, and some small-sized fused quartz sand in the agglomerate is easy to be carried out without being screened, resulting in incomplete screening.

[0025] In this embodiment, the conveying auger 3 conveys molten quartz sand, and the gravel can be discharged into the machine body 1 through the flexible joint 4 and the sand delivery pipe 5. During this process, the servo motor 8 drives the reciprocating screw 7 to rotate, which can control the cyclic swing of the sand delivery pipe 5 in the connecting sleeve 6. The gravel can be evenly laid on the screen, reducing the height of the gravel accumulation, increasing the gravel screening area, and improving the screening efficiency of the molten quartz sand.

[0026] Example 2, refer to Figure 4 A vibrating screen for the production and processing of fused quartz sand, wherein a first-stage screening box 10 and a second-stage screening box 11 are respectively provided at the top and bottom of the inner wall of the machine body 1, and main bars 12 distributed at equal distances are welded on the top of the screen of the first-stage screening box 10, and auxiliary bars 13 distributed at equal distances are provided between the two main bars 12.

[0027] In this embodiment, a plurality of main bars 12 and auxiliary bars 13 are respectively provided in the first-stage screening box 10 on the inner wall of the machine body 1. By utilizing the inverted triangle structure of the main bars 12 and the auxiliary bars 13, under vibration conditions, the agglomerated gravel is easily broken up when it contacts the main bars 12 and the auxiliary bars 13, thereby ensuring that the small particles of gravel can be fully screened and effectively improving the quality of the gravel.

Afterwards, the vibration motor 22 can drive the entire body 1 to vibrate, and the gravel will be screened in the first-level screening box 10. And using the inverted triangle structure of the main bar 12 and the auxiliary bar 13, under the condition of vibration, the agglomerated gravel is easily broken up when it contacts the main bar 12 and the auxiliary bar 13. The large-sized gravel will remain on the first-level screening box 10, and the small-sized gravel will fall into the second-level screening box 11. Finally, the first-level collecting barrel 23 and the second-level collecting barrel 24 collect molten quartz sand of different sizes respectively.
