Embodiment 2

[0048] Cut-off structure for the drain outlet of the reflux tank, such as Figure 5 As shown, on the basis of Embodiment 1, the driving mechanism is a motor 12 whose output end is fixedly connected to the top of the transmission shaft 9 , and the motor 12 is installed through a bracket 13 erected on the top of the slot 3 . In this embodiment, the motor 12 is used as the driving mechanism, and the rotation direction of the motor is set in advance, so that when the rotating shaft passes over the surface of the gate, it moves towards the center of the discharge groove; image 3 and Figure 4 The rotating shaft in is illustrated as an example, that is, the image 3 The axis of rotation in the clockwise direction, Figure 4 The shaft in the shaft rotates counterclockwise.

Embodiment 3

[0050] On the basis of any of the above-mentioned embodiments, among the two thickened portions 6 in this embodiment, the side wall of the thickened portion 6 located in the upstream direction is connected to the first deflector block 7, and the side wall of the thickened portion 6 located in the downstream direction Connect the second deflector block 8, the first deflector block 7 and the second deflector block 8 are wedge-shaped blocks whose bottom is in contact with the bottom of the reflux tank, and whose top is equal to the height of the tank wall 1;

[0051] The first deflector block 7 is located on the side of the corresponding thickened portion 6 facing the inner direction of the reflux tank, and the thickness of the first deflector block 7 gradually increases along the flow direction of the liquid in the reflux tank;

[0052] The second deflector block 8 is located on the side of the corresponding thickened portion 6 facing the center of the discharge port 2 , and the ...

Abstract

The invention discloses a stopping structure used for a drainage port of a backflow groove. The stopping structure comprises a groove wall and the drainage port located in the groove wall, inserting grooves are formed in the groove walls of the two sides of the drainage port, notches are further formed in the groove walls of the two sides of the drainage port, the notches are communicated with theinserting grooves in the same sides of the drainage port, and the notches are located in the sides, facing the interior of the backflow groove, of the inserting grooves; a rotating shaft is arrangedin the notches, and the outer surface of the rotating shaft is tangent to the plane where the groove walls of the side faces of the drainage port are located and the plane where the side walls of thesides, adjacent to the notches, of the inserting grooves are located; and a driving mechanism used for driving the rotating shaft to rotate is further included. The invention aims to provide the stopping structure used for the drainage port of the backflow groove, so that the problems that the lifting difficulty of a flashboard at a drainage port of a vibrating screen is high and the tank wall iseasy to deformation and being damaged due to forced knocking in the prior art are solved, and the purposes of conveniently and quickly lifting the flashboard and simultaneously avoiding damage and deformation of the tank wall are achieved.

Description

technical field [0001] The invention relates to the field of well site circulation systems, in particular to a cut-off structure for a discharge port of a backflow tank. Background technique [0002] In the field of oil drilling, the circulation system is one of the eight systems in the well site, which is used for the circulation of drilling fluid and completion fluid on the ground. The ground part of the circulation system includes backflow tanks, sedimentation tanks, mud tanks and other structures. The drilling fluid returned from the well enters the backflow tank from the wellhead, and flows through the backflow tank to the vibrating screen in the solids control system to screen out cuttings. It is impossible for the well team to be equipped with only one vibrating screen, because the processing capacity of a single vibrating screen cannot meet the processing demand during large-volume drilling, which will cause a large amount of drilling fluid to run out. Therefore, t...
