Description

Technical Field

[0001] The utility model relates to the relevant field of quartz sand processing, in particular to a fully automatic hydraulic grading device for fracturing quartz sand. Background Art

[0002] Fracturing sand is a kind of high-purity quartz sand, which is processed through the pure physical and zero-pollution production process of raw ore → pre-screening → scrubbing → desludging → coarse-grain classification → fine-grain classification → magnetic separation → concentration → dewatering screen → dryer → screening → finished product. It has super high compression resistance and extremely high roundness. It is mainly used in the oil and gas industry. Fracturing quartz sand usually needs to be automatically operated by a classifier when grading;

[0003] However, most of the quartz sand classifiers in the prior art do not have the ability to recycle wastewater. The wastewater generated by cleaning and grading quartz sand needs to be discharged to a designated area for treatment, which is troublesome. It not only consumes more costs but also easily causes waste of water resources. The existing classifier also has the problem of poor shock absorption. It is placed directly on the ground through a metal bracket-type base. The vibration generated when the motor is working directly acts on the bracket and the ground, which is prone to more friction and noise problems. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content
