Description

Technical Field

[0001] This application relates to the technical field of conveying equipment, and specifically relates to a drying and conveying equipment for quartz sand. Background Art

[0002] Quartz sand for fracturing is a kind of quartz sand specially used for fracturing processes in fields such as oil and natural gas. In oil and gas exploration and development, fracturing technology is a commonly used production-increasing measure. By injecting high-pressure liquid into the formation, fractures are generated in the formation, thereby increasing the oil and gas flow channels and improving the oil and gas production. As the main proppant in the fracturing fluid, quartz sand has characteristics such as high hardness, good wear resistance, and stable chemical properties, and can effectively support the fractures and prevent the fractures from closing, thus ensuring the fracturing effect.

[0003] A prior patent (publication number: CN212314962U) discloses a conveying equipment with a shock-absorbing structure for quartz sand production, including a discharge tank, a lift pump, a first drive motor, a pressure sensor, and a second drive motor. The upper surface of the discharge tank is fixedly connected with a first box body. A second box body is arranged on the right side of the first box body. The rear surface of the outer shell is connected with a first drive motor welded on the second box body. The outer surface of the shaft rod is fixedly connected with a pressure sensor.

The lower surface of the connecting block is connected with an adjusting plate. The top end of the support plate is fixedly connected with a top plate welded to the second box body. This conveying equipment with a shock-absorbing structure for quartz sand production can, when discharging materials at the end of material conveying, reduce the vibration caused by the drive mechanism through the shock-absorbing structure, thereby preventing the materials from spilling to other places.
