Embodiment 4

[0048] A hydraulic separation method for improving the cleanliness of quartz sand, comprising the following steps:

[0049] A. Prepare equipment

[0050]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. Specifically, in this embodiment, a vertical draw-in slot is arranged in the sorting box 1, and the dividing plate 4 is clamped in the drawing-in groove, so that it is convenient to replace the dividing plate 4 . In addition, the partit...

Embodiment 10

[0066] The parameter setting of this embodiment is completely consistent with that of Embodiment 4, and the difference between this embodiment and Embodiment 4 lies in that the structure of the water spray tray 8 used in step B is different. 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...

Abstract

The invention belongs to the technical field of quartz sand processing, and specifically discloses a hydraulic sorting method for improving the cleanliness of quartz sand. Sorting in a sorting box includes the following steps: continuously pouring clean water into the sorting box, and clear water The direction of water flow is upward; mix quartz sand particles and clear water to form a sand-water mixture, and mix the sand-water mixture with 100M 3 / H‑300M 3 The flow rate of / H passes into the sorting box from the side wall of the sorting box; the ultrasonic force is given to the quartz sand particles in the sorting box through the ultrasonic generator, and the frequency of the ultrasonic generator is 28KHz-42KHz; after the sorting is completed , discharge and collect the quartz sand particles in the sorting box. By adopting the technology of the invention, the requirement of cleaning during the sorting of quartz sand can be met.

Description

technical field [0001] The invention belongs to the technical field of quartz sand processing, and in particular relates to a hydraulic separation method for improving the cleanliness of quartz sand. Background technique [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, d...
