A control system for sorting quartz sand

Abstract

The invention relates to the technical field of automatic control, in particular to a control system for sorting quartz sand, which includes a control terminal, an overflow box and a sorting box. The overflow box is provided with a water inlet and its upper end is open. There is a sand inlet connected with the overflow box, and the height of the sand inlet is higher than the bottom of the overflow box. There is a row of sorting chambers in the sorting box, and the adjacent sorting chambers are separated by partitions. The selection box is equipped with a water supply mechanism that supplies water to each separation chamber respectively. The water supply mechanism includes a number of water spray holes, and the openings of the water spray holes are all facing upward. The water flow rate of the water supply mechanism and the water inlet, and the control terminal is also used to control the lifting of the partition according to the separation particle size of the quartz sand in each separation chamber. In this way, the separation efficiency of the quartz sand can be improved. This invention is mainly used in factories .

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control system for sorting 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.

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
