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 technological process of quartz sand needs to clean and dry the broken sand 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 The sorting method and sorting device of quartz sand have been studied, and this application focuses on the elaboration of the sorting device

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that the setting of the partition 9 is different, specifically, in combination with Figure 4 As shown, the partition 9 includes a fixed part 22 and a sliding part 21, the fixed part 22 and the sliding part 21 are plate-shaped, the fixed part 22 is welded in the sorting box 7, and the sliding part 21 is vertically slidably connected to the fixed part 22. On the right side, specifically, the side walls of the front and rear sides of the sorting box 7 are provided with chute, the fixed part 22 is slidably connected in the chute, and the top of the sorting box 7 is provided with a drive for driving the sliding part 21 to slide. Parts, in the present embodiment, the driving part is an air cylinder (not shown in the figure), and the output shaft of the air cylinder and the upper end of the sliding part 21 are fixed. In addition, the driving part can also choose the screw drive mode. Compared with the first embodimen...

Embodiment 3

[0056] The difference between this embodiment and Embodiment 1 is that the settings of the ultrasonic generator 20 are different, specifically, in combination with Figure 4 As shown, the number of ultrasonic generators 20 is 1 / 2 of the number of 8 sorting chambers, and the bottom of half of the sorting chambers 8 near the sand inlet 13 side is equipped with ultrasonic generators 20 correspondingly. The frequency of 20 is 33khz. During the implementation process, the sonotrode 20 is started intermittently, and the time interval between each start is 2-4s, and along the flow direction of the sand-water mixture, the start-up time interval of the sonotrode 20 is gradually increased.

[0057] Compared with Embodiment 1, in this embodiment, the frequency of the ultrasonic generators 20 is kept consistent, the number of ultrasonic generators 20 is reduced and the ultrasonic generators 20 are started intermittently, which can save energy to a certain extent. And supersonic generator...
