Problems solved by technology

[0002] At present, the production process of quartz sand in China mainly includes: mining, crushing, cleaning, drying, sorting, etc., and the sorting is generally carried out by vibrating screening machines. Set the particle size for sub-sieving to obtain quartz sand with different particle sizes (mesh numbers), but there are many problems in this screening method. First, the particle size of the sorted quartz sand is not uniform, and it is easy to mix some particles into the larger sand particles. The fine particles make the standard sand after sieving have different mesh sizes, resulting in the problem that the particle size distribution of the finished sand is not up to standard; secondly, during the working process of the vibrating screening machine, due to the impact between the sand particles or between the sand particles and the sieve plate, a large amount of dust, and the main component of dust, silicon

Example Embodiment

[0056] Example 10

[0057] like figure 1 Shown: a method for sorting quartz sand, comprising the following steps:

[0058] A. Prepare equipment

[0059] Prepare a sorting box 1 with a length of 6.4m, a width of 1.5m, and a height of 1.5m. A sand inlet 3 is provided on the right side of the sorting box 1, and a sand outlet is opened on the left side of the sorting box 1. Prepare a plurality of dividing plates 4 with different heights to meet the requirements of different heights of dividing plates 4 in the present application. In this embodiment, a plurality of dividing plates 4 with a height of 1 m are installed in the sorting box 1 along the horizontal direction, i.e. dividing plates The height of 4 is 2 / 3 of the height of the sorting box 1, and the partition plate 4 is detachable and replaceable. Specifically, in this embodiment, a vertical slot is arranged in the sorting box 1, and the partition plate 4 is snapped into the slot Inside, it is convenient to replace the par...

Example Embodiment

[0072] Example 13

[0073] The parameters used in this embodiment are exactly the same as those in Embodiment 10. The difference between this embodiment and Embodiment 10 lies in the structure of the water spray plate used in step B. Specifically, such as image 3 and Figure 4 As shown, the water spray tray 8 is rotatably connected to the water supply pipe 7, and the water spray holes 10 on the same water spray tray 8 are all arranged obliquely along the same direction of the circumference of the water chamber 9, and the water flows from each water spray hole through the water chamber 9. While 10 is discharged, the water spray plate 8 is subjected to the counterclockwise (or anticlockwise) thrust of the water flow, thereby rotating. A sand cleaning hole is provided at the bottom of the water spray tray 8. In order to reduce the diversion of the sand cleaning hole, only one sand cleaning hole is provided in this embodiment, and a sand cleaning pipe 11 is bonded at the sand c...

Abstract

The invention belongs to the technical field of quartz sand processing, and specifically discloses a method for sorting quartz sand. The method comprises the following steps that clear water is continuously fed into a sorting box, and clear water flows upwards; quartz sand particles and clear water are mixed into a sand-water mixture, and the sand-water mixture is introduced into the sorting box from the side wall of the sorting box at a flow rate of 100 M<3>/H to 300 M<3>/H; ultrasonic force is applied to the quartz sand particles in the sorting box through an ultrasonic generator, and the frequency of the ultrasonic generator is 28 KHz to 42 KHz; and the quartz sand particles in the sorting box are discharged and collected after sorting is completed. By adopting the process, the quartz sand can be cleaned while being sorted, and the production process of quartz sand is shortened.
