Automatic sand separating device for shale gas exploitation

Abstract

The invention discloses an automatic sand separating device for shale gas exploitation, and relates to the technical field of shale gas exploitation, the automatic sand separating device comprises a separating box, a filtering water tank, a first screw conveyer and a second screw conveyer, and the feeding position of the first screw conveyer is communicated with the separating box. A toothed area and a smooth tooth area are arranged on a first sliding seat and a second sliding seat in the reciprocating driving mechanism, the toothed area and the smooth tooth area are distributed at different positions on the first sliding seat and the second sliding seat, the first sliding seat and the second sliding seat are connected through a connecting rod, and through the action of a sliding groove, the toothed area and the smooth tooth area can be separated from each other. The first sliding seat and the second sliding seat move back and forth, so that the discharging door opening and closing mechanism and the sealing cylinder transmission mechanism are driven in sequence, the sealing cylinder and the sealing door are controlled to be started and closed in a crossed mode in sequence, shale gas is prevented from overflowing from the discharging position in the intermittent discharging process of the equipment, and the discharging efficiency is improved. And the influence of leaked shale gas on the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of shale gas exploitation, in particular to an automatic sand separation device for shale gas exploitation. Background technique [0002] Shale gas is a new type of underground non-renewable resource. Under the action of the crustal movement, the dead bodies of animals and plants are buried deep in the ground, and shale layers are formed under the long-term environmental action, and shale exists in the shale. Pores are formed inside the rock formation. Through technical operations such as drilling and fracturing, the shale gas in the shale layer can be exported according to the needs of use, and the resources in the fields of chemical technology and other fields can be replaced. The exported shale gas is due to fracturing. and other operations, in which there will be miscellaneous parts of gravel and water, which need to be separated and removed to facilitate the normal use of shale gas. [0003] In the pri...

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide an automatic sand separation device for shale gas exploitation, to solve the problem of rock gas leakage caused by long-term use in the prior art, which has a great impact on the environment, and the push plate is in the During the moving process, the sandstone will be blocked, making it difficult for the sandstone to be discharged, resulting in the accumulation of sandstone, affecting the use of the equipment, and affecting the overall working efficiency of the equipment.
