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 dioxide, poses a great threat to human health. If the vibrating screen is not tightly sealed, the dust will fly around in the production area. At the same time, the sand after sorting needs to be further cleaned. Finally, due to During the sand sorting process, the sand and the sieve plate of the vibrating screen are constantly collided, which reduces the durability of the sieve plate and makes the sieve plate need to be replaced after a period of use
Therefore, the method of vibrating screening is only suitable for small batch production
[0003] However, the current conventional process flow of quartz sand needs to clean and dry the broken sand particles before sorting, which makes the production process longer and is not suitable for enterprises with large quartz sand production. Based on the above problems, the applicant developed Developed a sorting method that can shorten the production process of quartz sand

Embodiment 14

[0046] The difference with embodiment 1, as attached image 3 As described above, only the structure of the spray pan 8 used in the step B is different. Specifically, the water spray plate 8 is rotatably connected to the water supply pipe, and the water spray holes on the same water spray plate 8 are arranged obliquely along the same direction of the circumference of the water cavity. The water spray pan 8 is pushed by the counterclockwise (or counterclockwise) direction of the water flow, so as to rotate. 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 cleaning hole. The sand pipe 11 is a rubber pipe, and the outlet of the sand cleaning pipe 11 is towards the root of the water supply pipe.

Embodiment 7

[0053] In Embodiment 7 and Embodiment 8, the injection flow rate of the sand-water mixture is changed, that is, the component force in the horizontal direction is increased, the horizontal component force increases, and the quartz sand particles at the sand outlet gradually increase, and the horizontal component force affects the outlet. The particle size of the quartz sand in the sand port has a greater influence, and the particle size of the quartz sand in the sorting box 1 also increases.

Embodiment 8

[0054] In Examples 8 and 9, the injection rate of the sand-water mixture increases, the flow rate of clear water increases, and the particle size of the quartz sand particles in the sorting box 1 and the sand outlet increases. In summary, the screening of quartz sand particles is affected by horizontal force (injection flow rate of sand-water mixture) and vertical component force (clear water flow rate injected into sorting box 1).

[0055] In Example 10 to Example 13, the frequency of the ultrasonic generator was gradually increased, and it was found that the particle size of the quartz sand at the sand outlet was basically the same, and the particle size of the quartz sand in the sorting box 1 was also basically the same. From the sorting results of Example 14, it can be seen that after changing the structure of the water spray tray 8, the particle size of the sorting is not greatly affected, but after changing the structure of the water spray tray 8, when the sand particles ...

Abstract

The invention relates to the technical field of quartz sand processing, and discloses a water injection type quartz sand sorting method, which is sorted in a sorting box, comprising the following steps: step A, passing clean water into the sorting box, and continuously flowing clean water into the sorting box , the flow direction of clean water is facing upwards, and the flow rate of clean water is adjusted to 1T / H~100T / H; step B, feed the sand-water mixture, mix the quartz sand particles and clean water to form a sand-water mixture; the sand-water mixture is 100M 3 / H~300M 3 The flow rate of / H is passed into the sorting box from the side wall of the sorting box; step C, completing the sorting, after the sorting is completed, the quartz sand particles in the sorting box are discharged and collected. The invention has a simple structure and can quickly screen the quartz sand.
