Background technique

In natural gas exploitation, a drilling machine is used to drill the bottom layer, and a drill bit is used for drilling. During the drilling process, a large amount of drilling fluid needs to be used. The drilling fluid is used to drive the drill bit to rotate at a high speed, and at the same time, a large amount of drilling fluid is returned to the well. Sewage, this kind of sewage contains a lot of mud and debris. If the sewage is directly discharged into the ditches, the debris and mud will block the river bed. In addition, the sewage will also cause a large number of deaths of aquatic products and vegetation in the ditches. Sewage needs to be treated. Studies have shown that the mud can be made into fertilizer for plant production after being recycled and matured, and the cuttings can be used as building materials. Therefore, people need to recycle the mud and cuttings. Because the mud and cuttings are mixed together, it is difficult to To separate the two, people currently use artificial salvaging of cuttings to fish out the cuttings. After salvage, the mud is allowed to settle and the upper layer liquid is pumped to complete the separation of the mud and cuttings.

The working process of the utility model is as follows: the worker turns on the sewage pump (3), and the sewage pump (3) pumps the sewage containing rock chips and mud into the separation cylinder (2) through the sewage pipe (9) and the elbow (10) in turn. ), the mud and liquid fall into the conical bin (5) through the filter hole (11), and the cuttings remain in the separation cylinder (2) because the particle size is larger than the diameter of the filter hole (11). , when a certain amount of sewage is discharged, the worker turns off the sewage pump (3), and turns on the motor A (13) at the same time. The motor A (13) drives the separation cylinder (2) to rotate, and under the action of centrifugal force, it adheres to the rock. The sludge on the cuttings is thrown off and enters the conical bin (5), thereby realizing the complete separation of sludge and cuttings, and at the same time improving the separation efficiency. After a period of time, the motor A (13) is turned off.

When the sludge in the conical silo (5) is left for a period of time, the sludge is completely deposited on the bottom of the conical silo (5), and the liquid floats on the upper layer of the mud. At this time, the worker opens the stop valve (8) first, The liquid is discharged from the shut-off valve (8) to the outside of the tank (4) through the overflow port (7). After the discharge, the worker opens the butterfly valve (6), and the sludge is discharged from the butterfly valve (6) under the action of gravity. After the worker closes the butterfly valve (6) and turns on the motor B (16), the motor B (16) drives the lead screw (18) to rotate, and the nut (17) on the lead screw (18) moves along the lead screw (18). When the cylinder (2) is outside the tank (4), the motor B (16) is turned off, and the worker injects hydraulic oil into the rodless cavity of the oil cylinder (12), and the piston rod extends downward. Loosen the screw (19) and remove the cover plate (15), the cuttings in the separation cylinder (2) roll out from the chip discharge port (14) along the slope at the bottom of the separation cylinder (2) to complete the collection of cuttings. Thus, the separation of sludge and cuttings is finally achieved. Therefore, the device replaces the original method of manually salvaging cuttings and sludge, greatly reducing the labor intensity of workers, while ensuring more thorough separation and improving separation efficiency.
