Description

TECHNICAL FIELD

[0001] The utility model relates to transportation device technical field, concretely is a kind of automatic sand conveyor of oil drilling. BACKGROUND

[0002] A large amount of sand, i.e. drill cuttings, is generated during drilling. After being separated by a shale shaker, the sand naturally deposits on the edge of a sewage pool below the shale shaker. Because the flowability of the sand is poor, it is difficult to transport the sand to a remote location. Therefore, the sand falling from the shale shaker can be transported to a suitable location by a sand conveyor.

[0003] In related art, drill cuttings carried by drilling fluid are separated from liquid under the action of vibration by a sand shaker. The sand falls into a receiving hopper, and the sand in the receiving hopper enters a sand conveying device through a dropping pipeline. Under the driving of a conveyor belt, the sand is conveyed to a designated location. However, during the entire screening and sand conveying process, fine dust is continuously released into the air due to factors such as material stirring, impact of falling, friction of mechanical parts, and the like. These suspended dust not only causes serious pollution to the surrounding environment and destroys the ecological balance, but also contains harmful substances such as minerals and heavy metals. If workers at the work site inhale these substances into their bodies for a long time, they are likely to induce a series of serious occupational diseases such as pneumoconiosis and lung cancer, which poses a great threat to the health of workers and further poses a serious challenge to the sustainability of manpower for drilling operations.
